Abstract

PURPOSE:To process data together in the next handshake and to shorten the processing time of data by providing a system interface which processes the accumulated data together in and after the second handshake in a receiver. CONSTITUTION:When a system interface 9 receives data from a reception part 8 and the first data is handshake processed with a remote control system, the next continuous data D is executed in terms of the first handshake process and accumulates reception at the same time. And the data code D accumulated in and after the second handshake is processed together. For example, a transmitter 1 has four switches a-d and when they are sequentially pushed and from the transmitter 1 four packets such as a b c d are continuously transmitted in the same custom code C, in the reception part 8 of a system receiver 7 (a) data is executed in handshake with the remote control system by the system interface 9. During the handshake process, the data b c d is received and accumulated and the data b-d is processed together in the next handshake.

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

First, an optical wireless system using optical communication will be explained. FIG. 1 shows a schematic configuration diagram of the entire optical wireless system, and FIG. 9 shows a schematic configuration diagram of a part of the wireless system combined with a general time division multiplex transmission remote control device, which will be described later. It is. As shown in FIG. It is placed and used.

A plurality of satellite receivers 2 that receive the optical transmission hood from the transmitter 1 are installed on the ceiling 28, and a unique address is set for each of the 7 transmitters 1 in which a large number of lighting fixtures 29 to be controlled are arranged. Furthermore, for example, control data for controlling the lighting equipment 29 on and off is transmitted together with address data as an optical wireless signal as shown in FIG. 4(a) as a transmission hood. As shown in FIG. 5(a), the transmission code of this optical wireless signal includes a head pulse HP such as a start pulse, a custom code C1 consisting of address data, etc.1 a data hood D1 such as control data, a rest period S1 an inverted custom code. C1 inverted data hood D
It consists of The custom code C is composed of 10 bits C0 to C3 as shown in Fig. 5(b), and depending on whether the upper pitch hcs is 0 or 1, other system operations such as a vibration temperature control device for time division multiplex transmission are performed. The system allows users to choose whether to perform individual operations in the wireless system. The lower 9 bits) C0 to C8 are arbitrarily set, and are used to set the address of the transmitter 1, etc.

FIG. 5(c) shows a 7-dimensional signal Y of data code D, which is composed of 8 bits D0 to D7. This data code D is an arbitrary setting, and data such as on/off of the load, dimming control in the case of a lighting load, etc. is set. Specifically, as shown in FIG. 3, the transmitter 1 which has a plurality of operation switches includes an address setting section 17 that allows the address to be arbitrarily set, a signal processing section 18 that creates a transmission hood, and an optical wireless transmission hood. A device including a light emitting section 19 made of a light emitting diode or the like for transmitting a signal, and a satellite receiver 2 for receiving an optical wireless signal are constructed as follows. That is, as shown in FIG. 1, an optical receiver 3 receives an optical wireless signal from a transmitter 1 and is composed of a charging element such as a PIN diode.
Satellite reception from a tuning circuit 4 having a tuning circuit 4 having a tuning function for detecting a carrier wave of an output signal from a baseband converting section 5 that converts the output of the tuning circuit 4 into a baseband signal as shown in FIG. 4(b). A container 2 is configured.

The baseband signal from the satellite receiver 2 is sent out on a dedicated signal C6 and transmitted to the system receiver 7 and a plurality of individual receivers 11 connected to the signal line 6. The system receiver 7 receives the baseband signals from the satellite receivers 2 all at once, and as shown in FIG. The setting unit 10 selects the address data, ?, which is converted from the baseband signal into a binary parallel signal by the receiver atW8. , a system interface 9 to which control data is input, and the like. This system interface 9 is connected to the signal line 34 of the multiplex transmission control system, and is processed according to the procedure on the central control unit 31 side. The receiving unit 8 of the system receiver 7 extracts only the set signal 7t-MatsuF from the baseband signal, the setting unit 10 determines whether it is a system operation or an individual operation, and receives the received address data and control data. The unit 8 outputs the data to the system interface 9.

As shown in FIG. 1, the individual receiver 11 includes a receiving section 12 that receives a 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 etc. 15. Note that a series circuit of a relay contact 14a driven by the load interface 14 and a load 15 is connected in parallel to the power supply 16.

Thus, the optical wireless signal transmitted from the transmitter 1 is received by the nearest satellite receiver 2, and the tuning circuit 4
Only the signal of the frequency determined by is detected, converted into a baseband signal by the baseband converter 5, and transmitted as a wired signal #16 to each receiver 1q-1 and IC1.゛Wireless signal custom code C upper pitch) C
If s has selected 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 custom code C of the optical wireless signal from the transmitter 1 selects system operation, the system receiver 7 will respond. In other words, the address converted from the baseband signal to a binary parallel signal,
The control data (custom code C1 data hood D) is input to the system interface 9 and is processed according to the procedures of the multiplex transmission remote control system.

Here, the transmitter 1 via the system interface 9
A remote control system for time-division multiplex transmission in which a transmission code from a computer is input will be described.

10 and 11, FIG. 10 shows a schematic configuration diagram of the remote control system, and the central controller 3
1 and multiple monitoring terminals 3 with unique addresses set.
2 and the control terminal 33 are connected by a pair of signal lines 34. The transmission signal Vs sent from the central control device 31 to the signal line 341 includes a start pulse signal ST indicating the start of signal transmission, a mode data signal MD indicating the signal mode, and a terminal device, as shown in FIG. 32, 33
A bipolar signal (±24 cm) consisting of an address data signal AD to call, a control data signal CD to control the load 37, a checksum data signal O8, and a return standby signal WT to set the return signal period from the upper V terminal 32.33. ) is a time-division multiplexed signal in which data is transmitted using pulse width modulation.

When the address data of the transmission signal Vs received via the signal #I 34 matches its own unique address data, each terminal device 32, 33 takes in the control data of the transmission signal Vs, and returns the transmission signal Vs. Standby signal W
The monitoring data signal is converted into a current mode signal (signal #
The i34 open circuit is short-circuited through an appropriate low impedance and sent back as a signal).

Further, the central control II device 31 always sends out a dummy transmission signal Vs, and when an interrupt signal Vi as shown in FIG. 11(b) returned from any of the monitoring terminals 32 is received, an interrupt occurs. Interrupt processing is performed to detect the terminal device 32, access the terminal device 32, and return monitoring data.

- On the other hand, when the monitoring terminal 32 receives a monitoring input, it generates an interrupt signal Vi in synchronization with the start pulse signal ST of the dummy transmission signal Vs.
returns its own unique address data in synchronization with the return standby signal WT of the address confirmation mode transmission signal Vs from;
The central control device 31 is configured to return monitoring data corresponding to the monitoring input when the transmission signal Vs of the interrupt access mode in response to an interrupt is transmitted from the central control device 31, and Control device 31
Control data to be transmitted to the control terminal 33 is created based on the monitoring data sent back to the control terminal 33. Also,
The monitoring terminal 32 is provided with an individual operation switch 35 that individually controls the negative 1N 37 such as lighting. Therefore, the transmission signal Vs including control data from the monitoring terminal 32 is time-division multiplexed and transmitted to the corresponding control terminal 3.
3, control data is taken in and the remote control relay 36 is driven to control the load 37.

Next, a case will be described in which the optical wireless system and the above-mentioned remote control system for time division multiplex transmission, which is another system, are combined. FIG. 8 shows a block diagram of the main parts of the system interface 9 that connects both systems. In the case of system operation, the transmission code from the transmitter 1 is received by the satellite receiver 2, and the address data and control data converted from the baseband signal transmitted from the satellite receiver 2 into binary parallel signals are sent to the system interface. 9 is input. This entered custom code C
, the data hood D is stored in the storage unit 20, and the stored custom code C etc. is stored in the address setting $22.
It is regarded as the address of the terminal device as seen from the central control unit 31. In this embodiment, up to four pieces of address data transmitted from each transmitter 1 are sequentially stored. When four custom codes C, etc. are stored, they are canceled by the canceling means 21, and the custom code C, etc. for the next transmitter 1 is stored. In the address setting section 22, the storage section 2
Since the custom code C etc. stored as 0 is used as the address of the terminal device (system receiver 7) as described above, this system receiver 7 is set as a terminal device seen from the central control device 31@ in the address setting unit 22. By accessing the assigned address, normal remote control of time division multiplex transmission is performed. Therefore, the control data from the transmitter 1 is stored in the system interface 9, and when the system receiver 7 is accessed, the control data (data code D) is transmitted to the central control unit rIt3 within the waiting period for the return of the transmission signal.
1, and the central control device 31 sends the data back to the corresponding terminal device 33 based on the control data taken in from the system receiver 7.
The terminal device 33 drives the remote control relay 36 to control the illuminator 29.

FIG. 9 shows a configuration diagram combining a time division multiplex transmission system and an optical wireless system consisting of a transmitter 1, a satellite receiver 2, and a system receiver 7.

In FIG. 9, a central control device 31, a terminal device 33 having a remote control relay, a system receiver 7, etc. are housed in a distribution board 24. Further, a transformer 23 for supplying power to the terminal device 33 is also arranged. Therefore, the optical wireless signal transmitted from the transmitter 1 is received by the satellite receiver 2, converted into a baseband signal by the satellite receiver 2, and transmitted to the system receiver 7 as a signal #a6.

Then, the custom code C etc. of the transmitter 1 is stored in the system receiver 7, which becomes the address of the terminal device 32, and the system receiver 7 is accessed by the central controller 31. It will be processed according to the normal procedures of the side.

Next, data processing when a remote control system and a wireless system are combined, which is the gist of the present invention, will be explained.Normally, data is exchanged between the remote control system and the system receiver 7 of the wireless system by handshaking. In particular, the present invention is characterized by its data processing. FIG. 2 shows 70-, which is the gist of the present invention, and the operation will be explained based on this FIG. Incidentally, since the basic operation is the same as described above, only the gist will be explained. First, there is a case where the wireless signal from the transmitter 1 is a data code D that sequentially operates the same custom code C. The data hood D is multi-coded so that it can be determined by a pause period S and a custom code C.

The system interface 9 receives and receives data from the receiving unit 8, first performs handshake processing on the first data with the remote control system, and simultaneously performs the first handshake processing on the following M consecutive data codes D. Perform reception accumulation. Then, data codes D accumulated in the second and subsequent handshakes are collectively processed. For example, transmitter 1 has switch 11b and eyd is 4.
If the four switches atbteld are pressed in sequence and four packets a-4b-4c-4d are transmitted from the transmitter 1 in succession with the same custom code C, the receiving section 8 of the system receiver 7 will: Handshake the insect a data with the remote control system through the system interface 9. During this handshake process, the data of b-40-4d is received and accumulated, and in the next handshake, b,
eyd is processed using the aggregated data. In other words, when the custom code C of the wireless signal is the same but the data (data code D) is different, and the mark signal (pause time between packets) which is sequential data is received, the data is summarized and the next This is a system processing method using handshakes.

By the way, as shown in Fig. fIIJ1, a light emitting diode display 8a is provided in the receiving section 8 of the system receiver 7, and when a signal for performing a system operation is received, the display 8a indicates the reception.

The upper bits of the custom code C of the transmitter 1 and the system receiver 7 are fixed by hardware, and in this embodiment, the upper two bits of the custom code C of the transmitter 1 and the system receiver 7 are combined (.

Further, if the packet format such as the number of pulses of the transmission hood, the pulse width, and the code inversion-match match, reception is displayed. Figure 7 shows 70- in this case, first, the baseband signal of the transmission hood is received, the upper two bits of the custom code C are compared with the setting value of the system receiver 7, and then the packet 7 is When the format is correct, the display 8a displays the reception. Therefore, after operating the transmitter 1, the display 8
By checking whether or not a is displayed, you can discover a switch code setting error on the transmitter 1 side. That is, the normal operation of the transmitter 1 is confirmed by the indicator 8a lighting up, but if the load is not operating, it can be determined that the switch code of the transmitter 1 is set incorrectly.

In such a case, it is effective when there are a wide variety of transmitters 1 and system receivers 7, such as in a remote control system.

Further, similarly to the above, in the case of the individual receiver 11 as well, the display 12a of the receiving section 12 displays reception. In this case, if all the bits of the custom code C to the individual receiver 11 match and the packet format matches, the reception section 12 of the individual receiver 11 will display the reception.
Since there are many individual types of individual control for individual receivers 11, custom code C is often fixed in hardware, and data code D is usually set to the switch of transmitter 1, as described above. Similarly, it is possible to determine a switch code setting error on the transmitter 1 side or a setting error due to load non-operation.

Further, FIG. 6 shows a system 70- that resets the reception process in the system receiver 7 when the waiting time due to the handshake process with the remote control system side when the transmitter 1 is operated exceeds a certain period of time. It shows. That is, as mentioned above, data handshaking is performed between the system receiver 7 of the wireless system and the remote control system, but the allowable operation time for the switch operation of the transmitter 1 (human intuitive) ), when the handshake is reversed due to the remote control system, the base spanned signal reception processing in the reception g8 of the system receiver 7 is reset in order to make the operation of the wireless system appear to be normal. This is what I did. That is, when a certain period of handshake time has elapsed, the receiving section 8 outputs a handshake reset signal to the system interface 9. Therefore, for example, there will be no sense of discomfort such as delays caused by the system operation time (which varies depending on handshake processing traffic, etc.) caused by the operation of the transmitter 1 configured like a wall switch. It is something that can make you feel uncomfortable.

[Effects of the Invention 1] As described above, in the wireless remote control system of the present invention, when the wireless signals sequentially transmitted from the transmitter are operation data of the same custom code, only the first data is transferred to the remote control system side. The receiver is provided with a system interface that performs shake processing, receives and accumulates successive data in parallel while performing first handshake processing, and processes the accumulated data collectively in the second and subsequent handshakes. Therefore, when the wireless signals sequentially transmitted from the transmitter by the system interface are operation data of the same custom code, only the first data is handshaked (with the remote control system side), and the subsequent consecutive By receiving and accumulating data in parallel while performing the first handshake process, and processing the accumulated data all at once during the second and subsequent handshakes, this method differs from handshake processing for each piece of data. Since the data is collectively processed in the next handshake, the data processing time is reduced.
