Abstract

PURPOSE:To process in the same duration when an operation switch is operated with one switch and to improve the answering quality of action by composing data corresponding to the respective operation switches of a transmitter operated in a certain period and providing a composition transmission means which makes the composed wireless signal transmit in the transmitter. CONSTITUTION:When operation switches are sequentially operates in order such as 1a, 1c, 1b and 1d, in a data composition part 2 each bit of a data code is set 1 so as to compose the data. As the operation switch 1a is operated first, the bit data in a data composition part 20 is 0001 and if the operation switch 1c(0100) is operated next, the bit data is 0101. In the same way when the operation switch 1b is operated it is 0111, when the operation switch 1d is operated it is 1111. Therefore the bit data composed in the data composition part 20 becomes a composition signal setting 1 to each bit which is shown in figure (e), so that the address data and the composition signal are set to be transmitted from the luminous part 19 of a transmitter 1. In the meantime a load is controlled based on the bit data set 1 of data code in an individual receiver.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a wireless system using optical wireless signals.

[Background Art] A transmitter includes a transmitter having a plurality of operation switches, each having a unique address, and a plurality of receivers that receive wireless signals consisting of the address data, control data for load control, etc. from the transmitter. Conventionally, in a wireless system in which a receiver that receives a time-division multiplexed wireless signal from a transmitter and has a matching address controls the load based on control data following the address data, the following problems have conventionally been encountered. had. That is, when a wireless system is deployed together with a lighting device, the transmitter is also used as a wall switch, and in this case, in an office or the like, there are two or more transmitters. Therefore, when fabricating two or more transmitters, it is more likely that they will be operated at the same time (sometimes they will be made one at a time, and others will be operated at the same time). The transmitter has a plurality of operation switches in order to control, for example, on/off of the lighting load, dimming, etc., and the data of each operation switch is a combination of signals where each bit is 0 and 1. In order to enable simultaneous operation of each operation switch, a system was adopted in which data corresponding to each operation switch was output in sequence. However, in this method, the time it takes to output the final data is the signal output time per packet multiplied by the number of operated switches. In this case, the following problems arise. First, there is a time lag between the operation of the transmitter's operation switch and the actual signal output. That is, although the operation switches are operated one after another or simultaneously, the data corresponding to these operation switches is temporarily stored in the transmitter, and the stored data is sequentially output (transmitted). Therefore, if the transmitter is portable, after repeatedly operating the operation switch, the transmitter may think that the signal transmission has finished and may place it in a place where the optical axis to the receiver is not aligned. data received may not be received. Next, since data is sent out sequentially, the operation time of a channel that is operated later is longer. Furthermore, when using multiple transmitters in the same space,
The signal transmission time from each transmitter increases, the possibility of simultaneous operation of multiple transmitters increases, and the probability of non-operation increases. Furthermore, when the amount of data increases, the operating time becomes longer and the life of the battery that powers the transmitter also becomes shorter.

[Object of the Invention] The present invention has been provided in view of the above-mentioned points, and even when operating the repeating switches of the transmitter at the same time, the processing can be performed in the same time as when operating one repeating switch. In addition, we aim to improve operational response, reduce current consumption of the transmitter, and improve transmission reliability when using directional transmission media such as infrared rays. ) This provides a wireless system that aims to improve transmission reliability by reducing the amount of roughness.

[Disclosure of the Invention] (Structure &) The present invention provides a wireless signal consisting of a transmitter having a plurality of operation switches, each having a unique address, and the above-mentioned address data from the transmitter, control data for load control, etc. The receiver is equipped with a plurality of receivers that receive time-division multiplexed wireless signals from the transmitter, and the receivers whose addresses match control the load based on the control data following the address data. In the system, the transmitter is provided with a composite transmitting means for synthesizing data corresponding to each operating switch of the transmitter operated within a certain period of time and transmitting the composite wireless signal,
The present invention is characterized in that data corresponding to each operation switch of the transmitter that is operated within a certain period of time is synthesized, and the synthesized data is sent out as a wireless signal.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

First, a wireless system using optical communication such as infrared rays will be explained. FIG. 6 shows a schematic diagram of the entire wireless system, in which a plurality of transmitters 1 for transmitting optical signals are provided. A plurality of satellite receivers 2 for receiving the optical transmission code (wireless signal) from the transmitter 1 are also provided. A unique address is set for each transmitter 1, and an optical wireless signal as shown in FIG. 7 (IL) is transmitted as a transmission code together with the address data, for example, control data for controlling on/off of illuminators. Ru.

As shown in FIG. 8, this optical wireless signal transmission hood consists of address data ΔD1 and control data CD. Here, the mode data SI preceding the address data AD is a mode for selecting whether to perform another system operation such as a remote control device for time division multiplex transmission, or to perform an individual operation in the wireless system.

Specifically, as shown in the fjIJ1 diagram, the transmitter 1 includes an address setting section 17 that allows addresses to be set arbitrarily, a signal processing g18 that creates transmission codes corresponding to the operation switches 1a to 1d, and operation switches 1a to 1d. When 1d is operated within a certain period of time, a data synthesis section 20 synthesizes data, and a light emitting section consisting of a light emitting diode or the like that transmits the synthesized data from the data synthesis section 20 or a single code as an optical wireless signal. It is composed of 19 mag. Incidentally, the data combining section 20 and the light emitting section 19 constitute a composite transmitting means.

On the other hand, a satellite receiver 2 that receives optical wireless signals
is structured as follows. That is, as shown in FIG. 6, the optical wireless signal from the transmitter 1 is received and the PI
An optical receiver 3 consisting of a photoelectric element such as an N diode, a tuning circuit 4 having the same side function for detecting a carrier wave of an output signal from this optical receiver 3, and an output of the tuning circuit 4 are shown in FIG.
The satellite receiver 2 includes a baseband conversion section 5 that converts into a baseband signal as shown in b).

The baseband IT from the satellite receiver 2 is sent out on a dedicated signal fiS and transmitted to the system receiver 7 and the plurality of individual receivers 11 connected to the signal A16. The system receiver 7 receives the baseband signals from the satellite receivers 2 all at once, and as shown in FIG. A system interface 9 and the like are input with address data and control data obtained by converting a baseband signal into a binary parallel signal in the receiving section 8. This system interface 9 is connected to the signal filter 34 of the multiplex transmission control system, and is connected to the central control unit 31fl.
It is processed according to the procedure of ll. The receiving unit 8 of the system receiver 7 extracts only the set signal 7 format from the baseband signal, the setting unit 10 determines whether it is a system operation or an individual operation, and the received address data and control data are sent to the receiving unit 8. output to the system interface 9.

As shown in Figure @6, the individual receiver 11 includes a receiving section 12 that receives the baseband signal from the satellite receiver 2;
Address setting section 1 for setting each unique address
3, and a load interface 14 that drives a load control relay and the like based on control data. That is, this individual receiver 11 compares the baseband signal with the set address of each individual receiver 11, and if they match, the load interface 14 drives a load control relay or the like, and the load 15 such as the lighting equipment is activated. It controls the Incidentally, a series circuit of a relay contact 14a driven by the load interface 14 and a load 15 is connected in parallel to a power source 16.

The operation when only one operation switch 1a of the transmitter 1 is operated will be explained. When the operation switch 1a is operated,
The data corresponding to the operation switch 1a is transmitted to the signal processing unit 1.
8, the data passes through the data synthesis section 20 as it is, and the data code is sent out as a wireless signal from the light emitting section 19. The optical wireless signal transmitted from the transmitter 1 is received by the nearest satellite receiver 2,
Only a signal of a determined frequency is detected by the tuning circuit 1184, converted to a baseband signal by baseband conversion gs, and transmitted to each receiver 91, 11 via a wired signal line 6. If the mode data SI of the transmission hood selects individual operation, the system receiver 7 does not respond and the individual receiver 11 becomes the target.

The address of the baseband signal is checked in each individual receiver 11, and if it matches the set address, the load interface 14 drives the relay based on the control data to control the load 15. Here, if the mode data SI of the optical wireless signal from the transmitter 1 selects system operation, the system receiver 7 will respond. That is, the address and control data obtained by converting the baseband signal into a binary parallel signal are input to the system interface 9, and are processed according to the procedures of the remote control system for multiplex transmission.

Next, the main points of the present invention will be explained. As shown in FIG. 1, the transmitter 1 is provided with, for example, four operation switches 18 to 1d, and these operation switches 1a to 1d.
1d is! @3 D0 of the data code as shown in Figure (a)
~D.

Therefore, when the operation switch 1aii:fi of the transmitter 1 is activated (depressed), the data 0001 shown in FIG. 3(b) is transmitted after the address data. Other operation switch 1
b to 1d correspond to PIS3 diagrams (c) to (e), respectively.

Each operation switch I11-1d has a different function, and each function may be controlled with respect to the load, and each operation switch 18-1d may be operated almost simultaneously. Now, as shown in FIG. 2, when each of the operation switches 1a to 1d is operated within a certain period of time T, conventionally, the data is temporarily stored in the order in which the operation switches 18 to 1d are operated and then sent out sequentially. was. Therefore, the present invention provides for each operation switch 1a to 1 in the data synthesis section 20 shown in FIG.
1dl:N corresponding data are synthesized.

As shown in FIG. 2, the operation switches are la and lc.

When lb and ld are operated in order, the data synthesis section 20 sets each bit of the data code to 1 and synthesizes the data. In this example, since the operation switch 1a is operated first, the bit data in the data synthesis unit 20 becomes oooi, and then when the operation switch 1c (0100) is operated,
It becomes 0101. When the repetition switch 1b is operated, 0
111, and when the reproducing switch 1d is operated, 11
It becomes 11. Therefore, the bit data created by the data synthesis section 20 becomes a composite signal in which each bit is set to 1 as shown in FIG. It will be sent.

- On the other hand, for example, in the individual receiver 11, the load is controlled based on the bit data in which 1 is set in the data code, which is control data as a composite signal following the address data. In other words, on the individual receiver 11 side, each bit of the data code corresponds to the control content, so when reading which bit data D0 to D is set to 1, the load is controlled based on that pitch data. It is something to do. Note that the data to be synthesized is data within a certain period of time T, and the data after that is synthesized anew. Furthermore, if there is only one piece of data within time T, only that piece of data will be transmitted. Therefore, compared to the case where the address data and control data corresponding to each operation switch 1a to 1d are sent sequentially, since the control data is sent in combination, it takes the same time as when repeating one operation switch. This means that the processing can be performed in a number of steps, improving operational responsiveness. It should be noted that the number of operation switches is not limited to four, and it goes without saying that the number of operation switches can be n.

By the way, when repeating multiple production switches at the same time,
From the perspective of the operator, even if he or she intended to operate multiple units at the same time, electrically, it appears as though they were being operated at the same time. Therefore, in the past, chattering was removed by switching the number of operation switches.1For example, when using a CPU, the number of steps increases, so if a CPU with a small capacity of 4 bits is used to reduce costs, There may be cases where it does not fit. Furthermore, when configuring it in terms of hardware, the circuit becomes complicated. Therefore, in order to eliminate the negative effects of
The method shown in Fig. 5 is adopted. That is, from the time t1 when the operation switch 1a is operated now to t2
After the chattering removal time 1' has elapsed, that is, from time t2 to t,
The operation state of the other operation switches 1b to 1d is checked during the judgment time T2, and all the operation switches being operated at that time are considered to have been operated at the same time. FIG. 5 shows the diagram 70-.

In the example of FIG. 4, the operation switches 1b to 1b within the determination time T2
Since 1d is being operated, the four repetition switches 1a~
It is assumed that 1d is being repeated simultaneously.

There is no need to perform processing on the input section of the operation switch, which simplifies the processing of the input section of the operation switch and reduces costs. Moreover, it is possible to perform chattering processing on an individual basis and perform processing with less effect similar to that in the case of inputting.

[Effect of the Invention 1] As described above, the present invention includes a transmitter having a plurality of operation switches, each having a unique address, and a wireless signal consisting of the address data, control data for load control, etc. from the transmitter. A wireless system comprising a plurality of receivers that receive time-division multiplexed wireless signals from a transmitter, and the receivers whose addresses match control the load based on control data following the address data. In this case, the transmitter is provided with a composite transmitting means for synthesizing data corresponding to each operation switch of the transmitter operated within a certain period of time and transmitting the composite wireless signal. By combining the data corresponding to each operating switch of the transmitter operated within a certain period of time, and transmitting the combined wireless signal, conventionally, data corresponding to each scratching switch is transmitted separately. Compared to previous models, the data corresponding to each operation switch is combined and sent, so processing can be performed in the same time as when operating a single operation switch, improving operational responsiveness. When multiple transmitters are used in a space, the signal transmission time from each transmitter is shortened, the possibility of simultaneous operation of multiple transmitters is reduced, and the probability of non-operation is reduced. This improves transmission reliability by reducing the amount of traffic within the same space, and also improves transmission reliability when using a directional transmission medium. Furthermore, when the power source of the transmitter is a battery, the transmission time of the wireless signal is shortened, so that current consumption can be reduced and the life of the battery can be extended.
