Description

DETAILED DESCRIPTION OF THE INVENTION When centrally managing and controlling lighting equipment, etc. using remote control technology, if the control area becomes large and the control input section is only in one place on the control panel, the present invention Since requests cannot often be met, it is desirable to divide the control area appropriately, install a sub-control panel for each control area, input various control information at that location, and perform detailed control.

The present invention has been provided in view of the above-mentioned points, and consists of dividing a plurality of terminals into groups, installing a sub-control panel for each control area of the grouped terminals, and using the sub-control panel to control the plurality of terminals. The purpose of this invention is to provide a time-division remote control method that aims to collectively control devices and perform detailed control using control information.

The present invention will be explained in detail below with reference to Examples. In FIG. 1, reference numeral 1 denotes a control panel, which creates and sends control signals to each terminal 3 based on information sent from a sub-control panel 2. The terminal devices 3 are for controlling appliances such as lighting equipment, and are divided into groups as shown in the figure, and sub-control panels 2 are installed for each group. Each terminal device 3 and sub-control panel 2 has a unique address. The transmission signal sent from control panel 1 is
As shown in the figure, it consists of a start signal Ss, followed by a terminal device address signal SA and a control signal Sc, and further consists of a return signal time period TR from the terminal device 3. The control panel 1 sends an address signal SA and a control signal Sc to each sub-control panel 2 and terminal device 3 in a time-division cycle. In this embodiment, the transmission signal from the control panel 1 is constantly read by each sub-control panel 2, and when the signal matches the address uniquely set for the sub-control panel 2, a key is input to the sub-control panel 2. This signal is returned to the control panel 1 in the return signal time period TR, and the control signal Sc is transmitted from this control panel 1 to the terminal devices 3 grouped by the sub control panel 2. This is to centrally control the lighting equipment etc. connected to the terminal device 3. Here, the configuration and operation of the control panel 1 will be briefly explained.

The control panel 1 detects return signals from the sub-control panels 2... and monitors the input information of each sub-control panel 2.... The logic operation unit 21 shown in FIG. 3 calculates and changes the control data memory 24 based on the operation input from the operation input unit 22 and the information input to the sub-control panel 2 from the reception processing unit 29. Or display section 2
In addition to calculating and displaying the display signal at 3, the address signal and control signal to be transmitted are calculated and sent to the transmission signal generation section 25 in synchronization with the transmission signal of the transmission signal generation section 25. The transmission signal generation section 25 receives the address and control signal sent from the logic operation section 21. It converts the signal into a transmission waveform and sends it to the transmission section 26, and at the same time sends a synchronization signal to the logic operation section 21. The transmitting section 26 converts the signal sent from the transmitting signal generating section 25 into a transmitting signal and sends it to the sub control panel 2 . The reception processing unit 29 includes a reception signal detection unit 28 and a reception determination unit 27.
8 detects the return signal sent from the sub control panel 2,
It is sent to the reception determination section 27. The reception determining section 27 determines whether the returned signal is correct data, and if it is correct data, sends it to the logical operation section 21. Note that the terminal device address signal SA of the transmission signal is of a time-division cyclic type in which it is sent again from 1 after going from 1 to MAX. Here, the signal SB sent from the sub-control panel 2 to the control panel 1 is sent within the return signal time TR. Therefore, the next control signal Sc is given to the terminal 3 having the address indicated by the terminal address signal SA to control the appliance. In the present invention, the sub control panel 2 also takes an l address for the terminal 3 and sends control information input from the keyboard 4 to the control panel 1 during the return signal time period. Explain in detail.

In FIG. 4, the signal shown in FIG. 2 inputted from the signal line 5 is detected by the pulse width detection circuit 6, and the address register 7 and control signal register 8 are reset by the start signal Ss. Synchronize. Next, address signal S
receiving the Al control signal SO, address registers 7 and 7, respectively;
Write into control signal register 8. Next, switch SW, ~
If the address set by SW8 and the contents of address register 7 match, the output of AND gate 9 becomes 1, and the output of Q of counter 10 and AND gate 11 are ANDed, and if it becomes 1, the return signal drive circuit is activated. 12, and sends it out as a return signal in accordance with the output of the third register 13. When the return signal is sent out, a pulse CP is issued, and a clock is applied to the first register 15, second register 16, and third register 13 via the 0R gate 14 to shift data. The input signal from the keyboard 4 is the signal encoded by the keyboard encoder 17! At this time, key-input the terminal device number and then the control information 0N or 0FF.
For example, if it is 130N, 1 is stored in the third register 13,
Information of 3 is entered into the second register 16 and information of 0N is entered into the first register 15. If the input information is 130N as in the previous example, the information will be input to the first register 15, second register 16, and third register 13, and at the same time, the counter 10 will count 3 and output Q = 1. Become.

In this state, the address signal SA of the signal from the control panel 1 and the setting address of the sub control panel 2 (SWl~
8) match, the output Q of the counter 10 and the output of the AND gate 9 are ANDed by the AND gate 11,
The return signal is input to G of the drive circuit 12 to put this circuit into operation. As a result, the contents of the third register 13 are sent to the control panel 1 during the return signal time period. When the transmission of 4-bit data is completed, a CP pulse is issued, and the data is shifted through the 0R gate 14 to the first register 15, second register 16, and third register 13, respectively.

Next, when the addresses match, a signal is sent out in the same way as the previous time, and when the third sending is completed, the reception confirmation signal is sent from the control panel 1 as a control signal at the next same address, and this signal causes the AND gate 9 The counter 10 is reset by the AND gate 18, and the sub control panel 2 does not issue a return signal until information is input three times from the keyboard 4 and the output of the counter 10 becomes Q=1. A time chart of this relationship is shown in FIG. In the above configuration, when the control information is sent from the sub control panel 2 using the time chart shown in Figure 5, it takes a considerable amount of time to send from address 1 to address 255, so it takes several seconds from key input to completion of processing. , unchanged.

Therefore, as shown in Fig. 6, if key input information is set in the sub control panel 2 set to address i, a return signal of 1 is issued, and when the control panel 1 receives the return signal, the key input information is set to address i again. By transmitting one frame, and then transmitting the signal to address i in the same manner a total of four times, and proceeding to the next address i+1 after collecting the information stored in the sub control panel 2, the key The time from input to the completion of information transfer is short, and the time from key input to completion of the leg bracing operation (information transmission from the control panel 1 to the target terminal 3) can be shortened. As described above, the present invention divides a plurality of terminal devices into groups, and installs a sub-control panel that controls the grouped plurality of terminal devices in a single unit on the same level as the terminal device.
When the address signal of this sub-control panel is received from the transmission signal time-divisionally transmitted from the control panel after the address is given and the format of control information is established to control the terminal device input from the keyboard of the sub-control panel. In the return signal period following the control signal of the transmission signal, the control information inputted from the keyboard is returned to the control panel, and if the control information does not finish with one return, one return signal from the control panel
When the same address signal after the cycle is sent out, the remaining control information inputted by the key is sent back from the sub control panel to the control panel within the return signal time period, and the control panel receives the return signal sent back from the sub control panel. If it matches the control information format, the control panel transmits a reception confirmation signal to the sub control panel after one cycle, the control panel creates a control signal from this leg restraint information, and transmits the control signal. Since the information is transmitted from the control panel to the corresponding terminal device in a time-division manner, various control information can be entered for each control area using the sub-control panel to perform detailed control.
