However, when building a remote control system horizontally, it is necessary to set addresses to the operation terminal 2a and the control terminal 2b. Conventionally, addresses were set using dip switches provided as address setting sections on each operating terminal 2a and control terminal 2b.

[Problem to be solved by the invention]

In the above conventional configuration, the installer has to operate the dip switch for setting the address on site, so it is easy to make mistakes in setting the address, resulting in duplicate addresses being set or addresses that should be set being omitted. I had something to do. If there is such an error in address setting, accidents such as abnormal operation of the remote control system are likely to occur. Therefore, the work of setting the address has become a factor that imposes a great burden on the constructor. The present invention aims to solve the above problems and provides a remote control system that does not require address setting on the user side and prevents addresses from being duplicated or missing. [Means for Solving the Problems] In the present invention, in order to achieve the above object, a plurality of operation terminals each having an operation switch and a plurality of control terminals connected to a load are connected to a signal line. When the operation switch of each operation terminal device is operated, a transmission signal is sent from the main control device that specifies the address set individually for each operation terminal device and each control terminal device. transmit,

This prevents them from being allocated or missing. In addition, since a serial number is set for each operation terminal and control terminal, the serial number can be used in place of the serial number, and if a reader is used to read the contents of the storage unit, the manufacturing date etc. can be determined in the event of a failure. It is easy to know.

【Example】

The basic system is similar to the remote control system explained in the section of the prior art, and as shown in FIG. The terminal device 2b is connected to the main controller 1 via a signal line r consisting of two lines. A correspondence relationship is set in advance between the operation terminal device 2a and the control terminal device 2b, and when the operation switch S is operated, the corresponding load is turned on and off. A transmission signal having a predetermined format is transmitted between the main control device 1 and the operation terminal 2a and the control terminal 2b using a time division multiplex transmission method. The format of the transmission signal includes, for example, a start signal indicating the start of signal transmission, a mode data signal indicating the mode, an address data signal specifying the operating terminal 2a and the controlling terminal 2b individually by address, and an operating terminal. A control data signal for transmitting control data for controlling the load connected to terminal 2b, a checksum data signal, and a signal return period for setting the data return period from the operation terminal 2a and the control terminal 2b. A configuration in which they are connected in sequence may be used. When performing time division multiplex transmission using such a format of transmission signal, the following operations may be performed. That is,
In the operation terminal device 2a and the control terminal device 2b, the address data of the transmission signal transmitted through the signal line l matches the address set individually in the operation terminal device 2a and the control terminal device 2b. At that time, the transmission signal is taken in, and data representing the status of the operation terminal 2a and the control terminal 2b is returned to the main control device 1 in synchronization with the signal return period of the transmission signal. However, the main controller 1 normally generates a transmission signal in which the mode data signal is a dummy mode, and the operation terminal 2a generates an interrupt signal when the operation switch S is operated. . When the main control device 1 receives an interrupt signal, it accesses the operation terminal 2a that generated the interrupt, detects the on/off state of the operation switch S in synchronization with the signal return period, and detects the operation terminal 2a. device 2a and control terminal device 2
The control data is transmitted by referring to a table set in the main control device 1 so as to associate the data with the control terminal 2b and accessing the corresponding control terminal 2b. By performing the above-described operations, the load can be controlled on and off in accordance with the operation switch S. The load connected to the control terminal 2b is turned on and off in response to the on/off of the operation switch S on the operation terminal 2a.
In addition to the above-mentioned method, there are also the following methods to turn it off. That is, the main control device 1 calls the operation terminal 2a and the control terminal 2b cyclically using each address, and returns a signal indicating that an on/off operation is being performed on the operation terminal 2a. When the data returned during the period is confirmed, the corresponding control terminal 2b is turned on.
It may also be controlled to turn off. By the way, as shown in FIG. 2, the main control device 1 includes a control section 11 consisting of a microprocessor, a first storage section 12 consisting of a RAM, a second storage section 13 consisting of an E2PROM,
It includes a transmitting/receiving circuit 14 serving as an interface for connecting the control unit 11 to the signal Iil. The first storage unit 12 stores information that changes from time to time, such as the status of the operation terminal 2a and the control terminal 2b when exchanging data with the operation terminal 2a and the control terminal 2b. stored,
The second storage unit 13 stores a program for operating the main controller 1 and a table representing the correspondence between the operation terminal 2a and the control terminal 2b. Further, the main control bag W, 1 is provided with a reset circuit 15 for returning to the initial state, and a power supply circuit 16 for supplying power to each part of the main control device 1. On the other hand, as shown in FIG. 3, each control terminal 2b includes a terminal processing section 21 consisting of a microprocessor, and a transmitting/receiving circuit 22 as an interface is provided between the terminal processing section 21 and the transmission line l. ing. Further, the power for the control terminal 2b is obtained by rectifying and stabilizing the transmission signal, and includes a power supply circuit 23 connected to the signal line r. The terminal processing unit 21 has an E2F
A storage section 24 consisting of a ROM, a relay control circuit 25 for controlling a relay connected to a load, a reset circuit 26 for initialization, and the like are connected. The programs for operating the terminal processing section 21 and the serial numbers individually set for each control terminal device 2b are stored in the storage section 24. For example, 6 serial numbers are stored in the storage section 24 as 20 bits of data.
The serial number is set at the time of manufacturing or shipping the control terminal 2b. The serial number is
A different value is set for each product, and with 20 bits, different serial numbers can be set for about 1,050,000 pieces (ζ220). If the serial number exceeds the upper limit, it is set again from 0. Even in this case, there is almost no possibility that control terminals 2b having the same serial number will be included in one remote control system. Note that if there is a possibility that serial numbers will be duplicated in one remote control system, the number of bits in the serial number may be increased (for example, it may be 25 bits or 30 bits). Here, the serial number is also used as the address of the control terminal 2b. The operation terminal 2a has the same configuration as the control terminal 2b except that the relay control circuit 25 as an output is not connected to the terminal processing section 21, but the operation switch S is connected as an input. are doing. When constructing a remote control system using the main control unit W1.14 operating terminal 2a and control terminal 2b configured as above, the address setting device 3 is used to connect the operation terminal 2a and the control terminal 2a. It is necessary to create a table in the main controller in which the correspondence relationship with the terminal device 2b is set. The address setting device 3 uses a signal line! when setting an address. The fourth
As shown in the figure, it includes an operation section 3], a setting processing section 32, a transmitting/receiving circuit 33, a power supply circuit 34, and the like. Operation unit 31
is equipped with a start switch that instructs the main control unit 1 to start setting the address, an address selection switch consisting of a numeric keypad (or numeric keys) that specifies the address, a changeover switch that specifies whether the load is on or off, etc. . FIG. 5 shows an example of the external appearance of the address setting device 3,
Here, the power switch 35 also serves as the start switch, and the address is specified using the address selection switch 36. In addition to specifying on/off using the changeover switch 37, the switching may be alternately performed each time the address selection switch 36 for specifying an address is operated. The address setting operation is performed as follows. That is, as shown in FIG. 1, when the address setting device 3 is connected to the signal line l and the address setting device 3 is operated, the main controller 1 3, enters the address setting mode, and requests the operation terminal 2a and control terminal 2b to return serial numbers. That is, if the address data transmitted from the main control device 1 and the serial number match, data indicating the match is returned to the main control device 1 during the signal return period. Note that if you set the serial number to 20 bits, if you check each one individually, you will end up transmitting up to 50,000 transmission signals, which will take a very long time, so set the offset value and check. It is desirable to shorten the search time for serial numbers by limiting the range or dividing it into upper bits and lower bits. As described above, the operation terminal 2a and the control terminal 2b are
When the serial number stored in the main controller 1 is stored in the main controller 1, the serial number stored in the main controller ]- is transferred to the address setting device 3 and stored in the setting processing section 32. In the address setting device 3, selection values of 1°2, . For example, 12345.12401, 12355.
When the control terminal 2b with the serial number 12350°12408 is connected, 12345→1,12
350 → 2,12355 → 3.12401 → 4,124
The correspondence relationship 08-5 is set. The operation terminal 2a and the control terminal 2b are given selection values for each type, and a type code set separately from the serial number is used to identify the type. In this way, each of the two repetition terminals 2a and the control terminal 2
After the serial number with b is stored in the main controller 1 and the correspondence with the selected value is set in the address setting device 3, the main controller 1 assigns a load to each control terminal 2b. Transmits control data to turn off and turns off all loads. In this state, when a selection value is selected using the address selection key 36 of the address setting device 3,
The main control device 1 transmits control data for turning on the load to the control terminal 2b having a serial number corresponding to the selected value, thereby turning on the load. In this state, the operation terminal 2 that you want to adapt to the load
When the operation switch S of a is operated, the main controller 1:
The correspondence between the serial numbers of the operation terminal 2a and the control terminal 2b is registered in a table provided in the second storage section 13. Any load that was on at this point will be turned off. In addition, when one load corresponds to a plurality of operation switches S, it is only necessary to turn on the load by the address setting device 3 and operate each operation switch S in order. When making the switch S correspond to a plurality of loads, with the address setting device 3 selecting a plurality of selection values in order and turning on the desired load,
All you have to do is operate the corresponding operation switch S. Furthermore, if the load turned on by the address setting device 3 is not the desired load, the changeover switch 37 may be operated to turn off the load. Below is an example of address setting operation, with 1 as the load.
It is assumed that two lighting loads L1 to L12 are provided, and are caused to blink by four operation switches 81 to S4 according to the following correspondence. (S1 → L 1 ), (S 2 → L
5. L6. L7. L8), (S3→L9, LIO), (
S4→Lll, L12), in this case, first, the address setting device 3 turns on the lighting load L1, and then operates the operation switch s1, and then the address setting device 3 turns on the lighting load L5, L. 6, L 7, L
8 is lit, operate the operation switch S2. Similarly, lighting load L9. With LIO turned on, operate the operation switch S3 to set the lighting loads Lll and L1.
All you have to do is operate the operation switch S4 with 2 turned on. After address setting by the address setting devices W and 3 is completed, if the address setting device 3 is removed from the signal line 1, the address setting mode is canceled, and each operating terminal 2a and each control terminal 2b has a memory. The address data stored in the section 24 is used as an address for each plane, and normal signal transmission is performed. According to the above configuration, although the serial number set at the time of manufacturing is used as an address, there is no need for the installer or user to set the address, and it is possible to prevent duplicate allocation or missing addresses. It is. Further, since a serial number is set for each operating terminal 2a and control terminal 2b, the serial number can be used as a manufacturing number, and the manufacturing date can be easily known in the event of a failure. Further, since the serial number is stored in the storage unit 24, it is necessary to use a reader to confirm the serial number, but there is an advantage that the serial number can be prevented from being changed by the user.

【Effect of the invention】

As described above, in the present invention, each operation terminal device and each control terminal device is provided with a storage section storing a serial number set at the time of manufacture, and the main control device Since the serial number of the machine is recognized as an address, there is no need for the user to set an address on each operation terminal or control terminal, and the serial number set at the time of manufacturing becomes the address. This has the advantage that it is possible to prevent addresses from being duplicated or missing. In addition, although serial numbers are set for each operation terminal and control terminal,
The serial number can be used in place of the manufacturing number, and by using a reading device that reads the contents of the storage section, the manufacturing date can be easily determined in the event of a failure.
