The light sensing component 11, the first memory 12, the indicator 14 and the first wireless transceiver 15 are all signally connected to the first processor 13, and the battery 16 is used to supply power (and form an electrical connection) to the light sensing device 10 Other power-consuming components include but not limited to the light sensing component 11 , the first memory 12 , the first processor 13 , the indicator 14 and the first wireless transceiver 15 . In other possible embodiments, the light sensing device may not include a battery, and may be externally connected to a commercial power source as its power source.

The light sensing component 11 is used to sense the illuminance or color temperature of the surrounding environment and send out a light sensing signal. Preferably, the light sensing signal is converted from an analog signal to a digital signal through an analog-to-digital converter.

The first memory 12, the first processor 13, the indicator 14, the first wireless transceiver 15 and the battery 16 can be but not limited to be integrated into a programmable logic controller (Programmable Logic Controller, PLC), and the indicator 14 can be at least A light-emitting component (such as LED) or at least one buzzer or a combination of a light-emitting component and a buzzer, the indicator 14 can be used to emit light or sound and other indication signals. In a preferred embodiment, the first processor 13 can sense the remaining power of the battery 16 and generate a remaining power signal.

The smart mobile device 20 can be but not limited to a smart phone, PDA or tablet computer, which includes a man-machine interface 21, a second memory 22, a second processor 23, a second wireless transceiver 24 and a battery 25. The man-machine interface 21, the second memory 22, and the second wireless transceiver 24 are all signally connected to the second processor 23, and the battery 25 is used to supply power to other power-consuming components in the smart mobile device 20, including but not limited to the man-machine An interface 21 , a second memory 22 , a second processor 23 and a second wireless transceiver 24 . Likewise, in other possible embodiments, the smart mobile device may not include a battery, and may be externally connected to a commercial power source as its power source.

The user can operate the smart mobile device 20 through the man-machine interface 21. The man-machine interface 21 usually includes a screen and an input component. function of the reader. In other possible implementation manners, the input component may be but not limited to other physical keys, keyboard or mouse.

The second memory 22 contains at least one of the upper limit and the lower limit of optical information (such as illuminance or color temperature) applicable to different usage scenarios. In a preferred embodiment, the optical information stored in the second memory 22 generally includes both the upper limit and the lower limit; in other possible embodiments, part of the optical information stored in the second memory 22 only includes the upper limit value or only the lower limit value.

As shown in Figure 2, the human-machine interface 21 allows the user to select one of the usage scenarios. In this embodiment, the selection panel of the usage scenario includes the location options 211 (such as "home", "office", "outdoor", etc. ) and action options 212 (such as "writing", "reading", "watching TV", etc.), when the user selects the location option and action option, in other words, when a specific use situation is selected, it will be corresponding to the second memory 22 Corresponding upper and lower limits of optical information.

In this embodiment, when the man-machine interface 21 is in a detection mode and the user has selected a specific use situation, as shown in FIG. The first wireless transceiver 15 and the second wireless transceiver 16 transmit to the second processor 23, and the light sensing signal received by the second processor 23 is displayed on the man-machine interface 21. At this time, the man-machine interface 21 is for example It can display the current use situation 213, the upper and lower limit values 214 of the optical information corresponding to the use situation 213, and the current light sensing signal value 215. At the same time, the second processor 23 can also determine whether the light sensing signal value is between Between the upper and lower limits, and according to the judgment result, a brief comment message 216 (such as "good" or "not good") is displayed on the man-machine interface 21 .

In addition, the smart mobile device 20 also feeds back the user's selection result of the usage scenario to the light sensing device 10 . At this time, the second processor 23 will sequentially transmit and store at least one of the upper and lower limit values of the optical information corresponding to the usage scenario selected by the user via the second wireless transceiver 24 and the first wireless transceiver 15 in the first memory 12, and then the first processor 13 can compare the light sensing signal sensed by the light sensing element 11 with at least one of the upper and lower limit values of the optical information stored in the first memory 12, and According to the result of the comparison, the indicator 14 is controlled to send a corresponding indication signal.

For example, when the first processor 13 judges that the illuminance value sensed by the light sensing component 11 is between the upper and lower limits of illuminance corresponding to the usage situation selected by the user, the first processor 13 can control the indicator 14 to emit Green light indicates that the current lighting environment is suitable for the use situation. In contrast, when the first processor 13 judges that the illuminance value sensed by the light sensing component 11 is higher than the upper limit or lower than the lower limit, it can control the indicator 14 to change to red light, indicating that the current lighting environment is not suitable. The context of use.

It should be noted that each time when the user selects a specific use situation, the corresponding upper and lower limit values of the optical information can be transmitted through the first and second wireless transceivers 15 and 24 and "stored" in the first The advantage of the memory 12 is that before the user changes another usage scenario, the light sensing device 10 can directly access the upper and lower limit values corresponding to the usage scenario as a basis for judgment, and the smart mobile device 20 The light sensing device 10 can also operate independently and send out corresponding indication signals without being placed near the light sensing device 10 at any time or maintaining wireless communication with it.

In this preferred embodiment, the working modes that can be selected by the user are not limited to the detection mode. For example, in FIG. 4, the human-machine interface 21 shows a control panel that includes a variety of operating modes for the user to switch between these operating modes, including but not limited to detection mode 217, battery status 218, lighting Mode 219 and night lighting mode 220 , after the user selects different working modes, the intelligent light sensing system will have different working performances.

For example, if the user clicks the "battery status" option, the first processor 13 will sequentially transmit and store the remaining power signal of the battery through the first wireless transceiver 15 and the second wireless transceiver 16 in the second memory 22, and then The second processor 23 can display the remaining power signal on the man-machine interface 21 .

When the user needs more lighting light, the user can click the "lighting mode" option, and the second processor 23 will send a lighting signal to the light through the second wireless transceiver 24 and the first wireless transceiver 15 in sequence. The sensing device 10 causes the indicator 14 to continuously emit light.

If the light-sensing component 11 is used to sense the illuminance of the surrounding environment, the user can also click on the "Night Lighting Mode" option. The device 15 sends a night lighting control signal to the first processor 14, and then the first processor 14 judges whether the light sensing signal (ie, the illuminance value) sensed by the light sensing element 11 is smaller than the night lighting stored in the first memory 12 If the starting value is 15 lux, if so, the first processor 14 sends a control signal to control the indicator 14 to emit light, so as to realize the function of actively providing night lighting.

In addition, please refer to Fig. 5, in this embodiment, the man-machine interface 21 also allows the user to select different user identifications 221, such as adults, elderly people and children, and the second memory 22 is loaded with corresponding to different user identifications. For example, the weighting parameter corresponding to "adult" may be 1, the weighting parameter corresponding to "elderly" may be 1.3, and the weighting parameter corresponding to "children" may be 0.8. When the man-machine interface 21 is in the detection mode and the user selects a specific user identification, the second processor 22 will multiply at least one of the upper and lower limit values of the optical information corresponding to the usage situation selected by the user by The weighting parameter corresponding to the user identification selected by the user, and the upper and lower limit values of the weighted optical information are sequentially transmitted through the second wireless transceiver 24 and the first wireless transceiver 15 and stored in the first memory 12 , the first processor 13 compares the light sensing signal sensed by the light sensing element 11 with at least one of the upper and lower limit values of the weighted optical information stored in the first memory 12, and according to the comparison result The control indicator 14 sends a corresponding indication signal.

Taking "elderly people" as an example, when the user selects "elderly people", the user identifies and selects the usage scenario of "watching TV at home", the second processor 23 will convert the optical data corresponding to "watching TV at home". Information (such as illuminance) lower limit value 150 lux is multiplied by the weighting parameter 1.3 corresponding to the user identification of "elderly" to obtain the weighted illuminance lower limit value 195 lux; similarly, the second processor 23 can also The illuminance upper limit corresponding to "watching TV at home" is multiplied by the weighting parameter 1.3 to obtain an illuminance upper limit of 390 lux suitable for "elderly people". The weighted upper and lower illuminance limits are passed through the second wireless transceiver 24 And the first wireless transceiver 15 transmits and stores in the first memory 12, so that the first processor 13 can compare accordingly to control the indicator 14 to send a corresponding indication signal.

In other possible implementation manners, the selection method of user identification may be to input age, gender or other identification information, and the second processor 23 may identify the corresponding user according to the input information such as age and gender.

Please refer to FIG. 6 , in addition to illuminance, the intelligent light sensing system of the present invention can also be applied to sensing technologies related to color temperature, and its working method is similar to that described above. In other possible embodiments, the photo-sensing device can also be built-in a photo-sensing component that can sense illuminance and a photo-sensing component that can sense color temperature, that is, it can be used for sensing both illuminance and color temperature. measure demand.
