Compared with the method that all devices connected with the current driving chip are configured in the device control instruction, the device identification of the device to be controlled is added into the device control instruction, so that the directional control of the designated device is realized, the redundant control of the device which does not need to be operated is avoided, and the data volume of transmission data is reduced.
Before determining the matched target lighting mode according to the instruction values of the first preset number of instruction data bits, constructing a target chip identifier according to the instruction values of the second preset number of instruction data bits, judging whether the target chip identifier is identical to the current driving chip identifier or not, and determining the matched target lighting mode according to the instruction values of the first preset number of instruction data bits, wherein if the target chip identifier is identical to the current driving chip identifier, continuing to determine the matched target lighting mode according to the instruction values of the first preset number of instruction data bits.

In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1A is a schematic diagram of a scenario suitable for the device control method provided by the embodiment of the present invention, as shown in fig. 1A, the driving chip is connected to the power supply through two power interfaces based on a non-polarity connection mode, that is, the two power interfaces are respectively connected to the power supply through wires with the same color and no identification, so that the power supply and the driving chip are connected in series (or in parallel) with each other, so that the driving chip can normally operate under forward and reverse voltages, and potential safety hazards caused by incorrect connection modes of the power supply can also be avoided. The voltage of the current flowing from one power interface to the other power interface is defined as positive voltage by the driving chip, and the voltage of the current flowing from the other current interface to the power interface is defined as negative voltage.
When the power supply externally supplies power, the energy storage device and the main control unit are powered by the power supply, when the power supply transmits data by changing the voltage direction, the power supply does not supply power to the driving chip at the moment in the interval time of the rising edge or the falling edge, the power supply supplies power to the main control unit, the power supply sends a device control instruction to the driving chip by changing the voltage direction, the driving chip controls the operation of target devices in a target lighting mode according to the obtained device control instruction, wherein the driving chip can be connected with one or more devices, in fig. 1A, the driving chip is connected with four devices, namely, the device A, the device B, the device C and the device D, and the device can comprise LED devices such as an LED screen or an LED lighting lamp.
Example 1
Fig. 1B is a flowchart of a device control method according to an embodiment of the present invention, where the method may be performed by a device control apparatus according to an embodiment of the present invention, the device control apparatus may be implemented in hardware and/or software, and the device control apparatus may be configured in a driver chip. As shown in fig. 1B, the method includes:
s101, detecting the voltage direction of a power supply in real time, and acquiring a first proportional relation between the duration of positive voltage and the duration of negative voltage in the current detection period.
The driving chip can configure one or more clock signals into one detection period and respectively detect the voltage direction of the power supply in each detection period, when the power supply supplies power normally, the power supply changes periodically with time due to the fact that the power supply is detected to meet the periodic change rule in the current detection period, the fact that transmission data do not exist in the current detection period is indicated, at the moment, the acquisition operation of a first proportion relation is not needed to be executed, and the fact that transmission data exist in the current detection period is indicated if the power supply is detected to not meet the periodic change rule in the current detection period.
As shown in FIG. 1C, in a detection period T, the power supply provides a positive voltage at time T1 and then provides a reverse voltage at time T2, the ratio of the duration of T1 to the duration of T2 is two to one, or the power supply provides a positive voltage at time T3 and then provides a reverse voltage at time T4, the ratio of the duration of T3 to the duration of T4 is one to two, in particular, in a detection period, the voltage direction of the power supply may be changed multiple times, for example, from positive voltage to negative voltage and then from negative voltage to positive voltage, so that in a detection period, the driving chip specifically records the ratio between the accumulated duration of the positive voltage and the accumulated duration of the negative voltage.
S102, determining the instruction value of the instruction data bit corresponding to the current detection period according to the first proportional relation.
Different proportional relations between positive voltage duration and negative voltage duration are configured as different instruction values in advance, the driving chip can acquire an instruction value corresponding to an instruction data bit in a detection period, for example, taking the power supply to transmit binary data to the driving chip as an example, for example, taking fig. 1C as an example, if the proportional relation between positive voltage duration and negative voltage duration is two-to-one, the instruction value of the current instruction data bit is "1", and if the proportional relation between positive voltage duration and negative voltage duration is one-to-two, the instruction value of the current instruction data bit is "0". The driving chip can determine the instruction value of the instruction data bit corresponding to the current detection period based on the mapping relation between the proportional relation and the instruction value according to the obtained first proportional relation.
In particular, when the power supply is controlling the voltage direction to change, there may be a control error, and when the driving chip is detecting the voltage direction to change, there may also be a detection error, so the first proportional relationship between the positive voltage duration and the negative voltage duration in the current detection period may not be exactly equal to two to one or one to two, but there may be a certain calculation error, and at this time, in the preconfigured proportional relationship, the instruction value corresponding to the proportional relationship closest to the first proportional relationship value is used as the instruction value obtained in the current detection period.
S103, determining a matched target lighting mode according to the instruction values of the first preset number of instruction data bits, and operating corresponding target equipment according to the target lighting mode.
The lighting pattern may comprise at least one of a brightness (e.g. of the order of 0 to 255, i.e. 256 total brightness levels), a color (e.g. red, orange, yellow, green, cyan, blue, violet or white, i.e. 8 total different colors) and a status (e.g. normally on and blinking, i.e. 2 total different status), the first preset number being related to the number of selectable parameters comprised by the lighting pattern, the larger the number of selectable parameters, the larger the number of first preset numbers, i.e. the lighting pattern requiring a larger number of data bits to fully characterize the device.
Taking the above technical solution as an example, 256 brightness levels may be represented by 8 data bits, 8 colors by 4 data bits, and states by 1 data bit, that is, a lighting manner of one device is represented by 13 data bits in total. If the driving chip is sequentially connected with four devices, then the complete device control instruction is obtained by sequentially obtaining the instruction values of 52 (i.e. 13×4=52) instruction data bits, and the operations of the devices are sequentially completed or completed in parallel accordingly.
Taking the technical scheme as an example, one possible device control flow includes setting the device A to be red light with 120-level brightness and displaying in a flickering state, setting the device B to be yellow light with 112-level brightness and displaying in a normally-on state, setting the device C to be green light with 150-level brightness and displaying in a flickering state, and setting the device D to be white light with 220-level brightness and displaying in a normally-on state for the device control instruction.
Optionally, in the embodiment of the present invention, the determining a matched target lighting mode according to the instruction values of the first preset number of instruction data bits and operating the corresponding target device according to the target lighting mode includes determining the matched target lighting mode and the target device according to the instruction values of the first preset number of instruction data bits and controlling the target device according to the target lighting mode.
Specifically, when the power supply sends out a device control instruction, the device identifier of the device to be controlled can be added into the device control instruction, so as to realize directional control of the specified device; taking the above technical solution as an example, if the driving chip is connected with four devices, the four devices can be distinguished by two data bits, and at this time, the directional control of the target device can be realized by 15 (i.e. 13+2=15) data bits, compared with the method that all devices connected with the current driving chip are configured in the device control instruction, the device identification of the device to be controlled is added into the device control instruction, so that the directional control of the designated device is realized, the redundant control of the device which does not need to be operated is avoided, and the data volume of transmission data is reduced.
Optionally, in the embodiment of the invention, after the voltage direction of the power supply is acquired in real time, the method further comprises the steps of acquiring a voltage waveform diagram of a current detection period and determining a matched target lighting mode according to the voltage waveform diagram. Specifically, due to the variety of voltage waveform changes, different voltage waveforms can be preconfigured for different lighting modes, the power supply can realize the transmission of equipment control instructions by continuously changing the voltage direction in one detection period, and after the driving chip acquires the voltage waveform diagram of the current detection period, the driving chip performs similarity comparison with each preconfigured voltage waveform, so that the equipment control instruction corresponding to the voltage waveform diagram can be determined.
For example, the two voltage waveforms in fig. 1D may be used to represent "red light of 120-level brightness" and "yellow light of 112-level brightness" in a blinking state and "normal-bright state", respectively; the matched target lighting mode is determined through the voltage waveform diagram, so that the transmission of the equipment control instruction is completed only in one detection period, and the data transmission efficiency between the power supply and the driving chip is greatly improved.
Optionally, in the embodiment of the invention, after the voltage direction of the power supply is obtained in real time, the method further comprises the steps of obtaining the voltage direction switching frequency in the current detection period, and determining the instruction value of the instruction data bit corresponding to the current detection period according to the voltage direction switching frequency. Specifically, the switching frequency of the voltage direction, that is, the frequency of converting from positive voltage to negative voltage or from negative voltage to positive voltage, may be compared with a preset frequency threshold. If the current voltage direction switching frequency is larger than or equal to a preset frequency threshold, determining that the instruction value of the instruction data bit corresponding to the current detection period is 1, and if the current voltage direction switching frequency is larger than or equal to the preset frequency threshold, determining that the instruction value of the instruction data bit corresponding to the current detection period is 0.
Referring to fig. 1E, if the preset frequency threshold is set to 3 times, the switching frequency of the voltages acquired in two detection periods in fig. 1E is 4 times and 2 times respectively, the command value corresponding to the former is "1", and the command value corresponding to the latter is "0". Compared with the duration time of detecting the positive voltage and the negative voltage, for detecting the voltage direction switching frequency, only the quantity of inflection points in the voltage change is required to be detected, so that the detection data quantity of the driving chip is greatly reduced, and the acquisition efficiency of the instruction value is improved.
According to the technical scheme provided by the embodiment of the invention, after the first proportional relation between the positive voltage duration and the negative voltage duration in the current detection period is obtained, the instruction value of the instruction data bit corresponding to the current detection period is determined according to the first proportional relation, the matched target lighting mode is further determined, and the corresponding target equipment is controlled to operate according to the target lighting mode, so that the driving chip realizes data transmission based on the change of the power supply voltage on the premise that the data transmission module is not required to be configured, the performance defect of the data transmission module is avoided, the problems of lower data transmission efficiency or higher data packet loss rate and the like are solved, the data transmission efficiency and the data transmission quality of the driving chip are improved, and the complexity of data transmission logic is reduced.
Example two
Fig. 2 is a flowchart of a device control method according to a second embodiment of the present invention, where, based on the first embodiment, the driver chip determines whether the driver chip is a receiving object of a control instruction sent by the power supply before determining a matched target lighting mode according to the instruction value of the first preset number of instruction data bits. As shown in fig. 2, the method includes:
s201, detecting the voltage direction of a power supply in real time, and acquiring a first proportional relation between the duration of positive voltage and the duration of negative voltage in the current detection period.
S202, determining the instruction value of the instruction data bit corresponding to the current detection period according to the first proportional relation.
S203, constructing a target chip identifier according to the instruction values of the second preset number of instruction data bits, and judging whether the target chip identifier is the same as the current driving chip identifier.
When the power supply is connected with a plurality of driving chips at the same time, the power supply can respectively send out equipment control instructions to different driving chips in turn in a polling mode, and can only send out equipment control instructions to part of the driving chips according to actual demands, at the moment, the power supply firstly sends out identification information of a target driving chip to be controlled, namely a target chip identification, through changing the voltage direction, the current driving chip firstly obtains the target chip identification according to a second preset number of instruction values and compares the target chip identification with the identification information of the current driving chip, wherein the second preset number is related to the number of the driving chips connected with the power supply, the more the number of the driving chips is, the larger the number of the second preset number is, namely a plurality of data bits are needed to distinguish different driving chips.
In particular, for the chip identifier and the lighting mode, the same instruction value may be configured as different proportional relationships, so that through the first proportional relationship obtained currently, it may also be determined whether the first proportional relationship represents the instruction value in the chip identifier or the instruction value in the lighting mode, for example, if the first proportional relationship is one to two, it represents that the instruction value corresponding to the current detection period is "1" and the instruction value is a data bit value in the lighting mode, if the first proportional relationship is two to one, it represents that the instruction value corresponding to the current detection period is "0" and the instruction value is a data bit value in the lighting mode, if the first proportional relationship is one to four, it represents that the instruction value corresponding to the current detection period is "1" and the instruction value is a data bit value in the chip identifier, and if the first proportional relationship is four to one, it represents that the instruction value corresponding to the current detection period is "0" and the instruction value is a data bit value in the chip identifier.
If the identification information of the target chip is different from the identification information of the current driving chip, the device control instruction sent by the power supply is irrelevant to the current driving chip, namely the current driving chip is not a receiving object of the control instruction sent by the power supply, at the moment, the current driving chip can suspend the voltage direction detection of the power supply in the next first preset number of detection periods so as to reduce the detection load of the driving chip, and after the first preset number of detection periods are passed, the detection of the voltage direction of the power supply is resumed.
S204, if the target chip identification is identical to the current driving chip identification, continuing to determine a matched target lighting mode according to the instruction values of the first preset number of instruction data bits.
And at the moment, the current driving chip continuously acquires a first proportional relation between the duration of the positive voltage and the duration of the negative voltage in each detection period, determines the instruction value of the instruction data bit corresponding to the current detection period according to the first proportional relation, and then determines a matched target lighting mode according to the instruction value of the first preset number of instruction data bits. Therefore, the directional control for the specific driving chip is realized, the consistency of the driving chip and the instruction sending object of the power supply is ensured, and the error response of the driving chip to the irrelevant instruction is avoided.
S205, running the corresponding target equipment according to the target lighting mode.
According to the technical scheme, before the driving chip determines the matched target lighting mode according to the instruction values of the first preset number of instruction data bits, the target chip identification is constructed according to the instruction values of the second preset number of instruction data bits, and when the target chip identification is identical to the current driving chip identification, the matched target lighting mode is continuously determined according to the instruction values of the first preset number of instruction data bits, so that the directional control of a specific driving chip is realized, the consistency of the driving chip and an instruction transmitting object of a power supply is ensured, and the error response of the driving chip to irrelevant instructions is avoided.
Example III
Fig. 3A is a flowchart of a device control method according to a third embodiment of the present invention, where, based on the first embodiment, a first numerical relationship between a positive voltage and a negative voltage is obtained while a first proportional relationship is obtained. As shown in fig. 3A, the method includes:
S301, detecting the voltage direction of a power supply in real time, and acquiring a first proportional relation between the duration of positive voltage and the duration of negative voltage in the current detection period and a first numerical relation between the positive voltage and the negative voltage.
The first numerical relationship may be a proportional relationship (i.e. a second proportional relationship) between a positive voltage value and a negative voltage value, or a magnitude relationship between a positive voltage value and a negative voltage value, for example, whether the positive voltage is equal to the negative voltage and both are 1V, and whether the positive voltage is equal to the negative voltage and both are 2V.
S302, determining the instruction value of the instruction data bit corresponding to the current detection period according to the first proportional relation.
S303, determining a matched target lighting mode according to the instruction values of the first preset number of instruction data bits, and determining matched target equipment according to the first numerical relation.
When determining a matched target lighting mode according to the instruction value of the first preset number of instruction data bits, if the identification information of the target device is added in the target lighting mode, a new instruction data bit needs to be added to record the identification information of the target device, as in the technical scheme above, the original lighting modes such as brightness, color and state can be represented by 13 data bits, but in order to distinguish different devices connected with the current driving chip, 2 data bits are added to represent different devices, namely, the directional control of the target device can be realized by 15 data bits.
In the embodiment of the invention, the identification information of the target device can be represented by a first numerical relation between positive voltage and negative voltage, as shown in fig. 3B, for example, -1V and +1v can be used for representing the device a, -2V and +2v can be used for representing the device B, -3V and +3v can be used for representing the device C, and-4V and +4v can be used for representing the device D, in fig. 3B, the proportional relation between the positive voltage duration and the negative voltage duration of the four devices is the same, the device a, the device B, the device C and the device D are in the same lighting mode, and when the driving chip acquires the first numerical relation between the positive voltage and the negative voltage in the current detection period, the device control command of the current device can be determined according to the first numerical relation, so that the directional control of different devices is realized while the command data bit is not increased, and the transmission efficiency of the device control command is improved.
S304, running the corresponding target equipment according to the target lighting mode.
Optionally, in the embodiment of the present invention, the determining the matched target lighting mode according to the instruction value of the first preset number of instruction data bits further includes determining a matched target data type according to the first numerical relation, and determining the matched target lighting mode according to the target data type and the instruction value of the first preset number of instruction data bits.
Specifically, the obtained first numerical relationship may also be used to represent different data types, as shown in fig. 3C, for example, binary data, octal data, decimal data, hexadecimal data, and the like. As described in the technical scheme, binary data can be represented by-1V and +1V, octal data can be represented by-2V and +2V, decimal data can be represented by-3V and +3V, hexadecimal data can be represented by-4V and +4V, and when a first numerical relation between positive voltage and negative voltage is obtained in a current detection period, a driving chip can determine the data type of instruction data of a current instruction data bit according to the first numerical relation.
In particular, under different data types, the number of possible instruction values of one instruction data bit is different, for example, the binary data only needs to configure two numerical relationships, namely, the numerical values of 0 and 1, respectively, while for decimal data, 10 numerical relationships, namely, the numerical values of 0 to 9, respectively, need to be configured.
