[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control relay unit for remotely controlling the opening and closing of contacts of a relay that controls a load.

[0002]

2. Description of the Related Art Conventionally, a load control system has been proposed in which a contact of a relay is inserted in a power supply path of a load, and an instruction device provided at a place different from the relay instructs opening and closing of the contact of the relay. There is. In this type of load control system, if the indicator and each relay are directly connected, the wiring becomes very complicated.Therefore, connect each terminal with an address set to each relay, and connect the indicator and the terminal. It is conceivable that, between the terminals, control data with address data is transmitted and received, and the terminal device that has received the control data from the instruction device controls each relay by giving a load control signal to the relay. In other words, while using the address to identify each terminal connected to each relay individually, it is possible to multiplex and use the transmission line connecting between the indicating device and each terminal, and It is greatly reduced.

For example, in the example shown in FIG. 20, a plurality of relay control terminals 51 are branch-connected (or bus-connected) to a transmission processing device 50 via a two-wire transmission line Ls to control each relay. The terminal 51 controls the opening and closing of the contacts of the relay 52. Each relay control terminal 51 is configured to be able to individually control up to four relays 52. That is, the transmission processing device 50
In addition to the address data for identifying each relay control terminal 51, the transmission signal transmitted between the relay control terminal 51 and up to four relay control terminals 51 connectable to one relay control terminal 51 The load number for identifying the relay 52 is included. As an instruction device for instructing opening / closing of the contact of the relay 52, an operation terminal device (not shown) with a switch branched and connected to the transmission line Ls can be used. In this type of operation terminal device, operation data is transmitted to the transmission processing device 50 by operating a switch, and the transmission processing device 5
In the case of 0, the transmission signal is transmitted to the relay control terminal 51 having the address which has a preset correspondence with the address set in the operation terminal to control the relay 52. Further, the transmission signal may be transmitted to the relay control terminal device 51 according to a program registered in advance in the transmission processing device 50 or the like. That is, in this case, the transmission processing tank 50 serves as an indicating device.

Further, a power transformer 53 for stepping down commercial power is provided, and the power transformer 53 and the relay control terminal 5 are provided.
By connecting 1 and the relay 52 via the power supply line Lp, the output of the power supply transformer 53 is used for driving the relay 52.

[0005]

As described above, if the relay 52 is controlled by using the relay control terminal 51, the number of wires is greatly reduced as compared with the case where the indicating device and the relay 52 are directly connected. However, since it is necessary to connect the power supply line Lp from the power transformer 53 to each relay control terminal 51 and each relay 52, it is not possible to sufficiently reduce the number of wires and it takes time to construct. It is such a thing. Further, if the relays 52 are arranged in a distributed manner, the power supply line Lp connected to the relays 52 will be routed, which makes the wiring work even more troublesome. Further, since the relay control terminal 51 and the relay 52 are separate bodies and the power transformer 53 is required, there is a problem that the occupied space becomes large.

BEST MODE FOR CARRYING OUT THE INVENTION An example of a load control system that can use the remote control relay unit of each embodiment will be described below. In the load control system shown in FIG.
Illumination load L is illustrated as a load, and a maximum of four illumination loads L can be individually controlled by one terminal processing block 30. That is, in addition to the address individually given to each terminal processing block 30, a 2-bit load number is set in each terminal processing block 30,
It is possible to select which lighting load L is controlled by designating the load number. Further, each lighting load L can be controlled only to be turned on / off here, and the opening / closing of the contacts of the latching relay 20 is controlled by a load control signal output from the terminal processing block 30. By inserting the contact point into the power feeding path to the lighting load L, the lighting load L can be controlled to be turned on and off. The operation terminal device 54 is provided with a maximum of four switches S, and each lighting load L is individually controlled by using a load number as in the terminal processing block 30.

A plurality of operating terminals 54 and a plurality of terminal processing blocks 30 are provided, and are connected to the transmission processing device 50 via a two-wire transmission line Ls. Operation terminal 5
4 and the terminal processing block 30 are respectively set with individual addresses, and the transmission processing device 50 individually recognizes the operating terminal 54 and the terminal processing block 30 by using these addresses.

The transmission processing device 50 is connected to the transmission line Ls by
The transmission signal Vs having the format shown in FIG. 19A is transmitted. That is, the synchronization signal SY indicating the start of signal transmission, the mode data MD indicating the mode of the transmission signal Vs, the address data (including the load number) AD for individually calling the operation terminal 54 and the terminal processing block 30, the lighting load. L
A control data CD for controlling the transmission, a checksum data CS for detecting a transmission error, a bipolar signal transmission period WT which is a time slot for receiving a return signal from the operation terminal 54 or the terminal processing block 30, and a bipolar (± 24V) time division multiplexed signal, and data is transmitted by pulse width modulation (FIG. 19 (b)). In each of the operation terminals 54 and each of the terminal processing blocks 30, when the address data AD transmitted by the transmission signal Vs received via the transmission line Ls matches the preset address, the control signal CD is transmitted from the transmission signal Vs. Of the transmission signal Vs and returns the data as a current mode signal (a signal sent by short-circuiting the transmission line Ls via an appropriate low impedance) during the signal return period WT of the transmission signal Vs.

When data is transmitted from the transmission processing device 50 to the desired operation terminal 54 or the terminal processing block 30, the mode data MD is set to the control mode and the address of the operation terminal 54 or the terminal processing block 30 is set. If the transmission signal Vs used as the address data AD is transmitted and this transmission signal Vs is transmitted to the transmission line Ls, the operation terminal 54 or the terminal processing block 30 that matches the address data AD.
Receives the control data CD and returns a signal obtained by adding a parity bit to the control data CD in the signal return period WT. In the transmission processing device 50, when the transmitted signal matches the received signal in the signal return period WT, the control data CD
Is the desired operation terminal 54 or terminal processing block 30
Confirm that it was transmitted to. Further, the terminal processing block 30 controls the load according to the received control data CD (the operation terminal 54 displays the operation confirmation of the lighting load L according to the received control data CD).

On the other hand, the transmission processing device 50 always sends out the transmission signal Vs in which the mode data MD is in the dummy mode at regular time intervals, and the operation terminal device 54 / terminal processing block 30 sends the transmission signal Vs to the transmission processing device 50. When transmitting some information by using the dummy mode transmission signal Vs
19C, an interrupt signal as shown in FIG. 19C is generated in synchronization with the synchronization signal SY. At this time, the operation terminal device 54 and the terminal processing block 30 set an interrupt flag to prepare for the subsequent information exchange with the transmission processing device 50. When the transmission processing device 50 receives the interrupt signal, it sets the mode data MD to the interrupt polling mode and sequentially increases the upper half bits of the address data AD (upper 4 bits if the address data AD is 8 bits). In the operation terminal 54 / terminal processing block 30 which has transmitted the transmission signal and generated the interrupt signal, the upper 4 bits of the address data AD of the transmission signal in the interrupt polling mode are the operation terminal 54 / terminal processing block 30. When it matches the upper 4 bits of the address set to, the lower half bits of the address are returned to the transmission processing device 50 during the signal return period WT. In this way, the transmission processing device 50 collectively searches for 16 operation terminals 54 / terminal processing blocks 30 that have generated an interrupt signal, so that the operation terminals 54 / terminal processing block 30 can be searched in a relatively short time. Can be found. When the transmission processing device 50 acquires the address of the operation terminal device 54 / terminal processing block 30 that generated the interrupt signal, the mode data MD is set to the monitoring mode, and the transmission signal having the acquired address data AD is sent to the transmission line Ls. In response to this, the operation terminal 54 and the terminal processing block 30 return the information to be transmitted during the signal return period WT. Finally, the transmission processing device 50 sends a signal for instructing an interrupt reset to the operating terminal 54 / terminal processing block 30 that generated the interrupt signal, and the operating terminal 54 / terminal processing block 30 interrupts. Clear the inclusion flag. As described above, information transmission from the operation terminal device 54 / terminal processing block 30 to the transmission processing device 50 is performed four times by the signal transmission from the transmission processing device 50 to the operation terminal device 54 / terminal processing block 30. Dummy mode, interrupt polling mode, monitoring mode, interrupt reset). Transmission processor 5
When 0 wants to know the operating state of the desired operation terminal 54 / terminal processing block 30, it suffices to send a transmission signal using the mode data MD as the monitoring data.

As is apparent from the above-mentioned operation, in the transmission processing device 50, the switch S provided on the operation terminal 54 is used.
Is operated, the control data to be transmitted to the terminal processing block 30 to which the lighting load L having the correspondence with the switch S is connected is generated based on the operation data returned from the operation terminal 54. Then, the transmission signal Vs including the control data is transmitted to the transmission line Ls, the control data is transmitted to the corresponding terminal processing block 30, and the lighting load L is transmitted.
Control.

In this type of remote monitoring control system, the individual control is performed so that the lighting load L corresponds to the switch S in a one-to-one correspondence, and the plural lighting loads L are associated with one switch S and collectively controlled. It is possible to control. further,
As for the collective control, it is possible to perform group control for controlling the plurality of lighting loads L to the same state and pattern control for setting the plurality of lighting loads L individually in a preset control state. In this way, each switch S is individually controlled,
The lighting load L is controlled by either the group control or the pattern control. The correspondence between addresses including the load numbers of the operation terminal 54 and the terminal processing block 30 is one-to-one correspondence in the individual control, and one-to-many correspondence in the group control and the pattern control. Also,
Such correspondence is registered in the transmission processing device 50 as a correspondence table.

The operation terminal 54 and the terminal processing block 30
The internal power source of the transmission signal V is transmitted through the transmission line Ls.
It is obtained by full-wave rectifying and stabilizing s. In other words, since the transmission signal Vs is bipolar and is always transmitted from the transmission processing device 50 to the transmission line Ls including the one in the dummy mode, full-wave rectification of the transmission signal Vs can be used to obtain the power source of the internal circuit. You can Further, since the terminal processing block 30 controls the latching relay 20 by the load control signal, and the latching relay 20 needs to flow the current only when switching the opening and closing of the contact, the transmission signal Vs is used from the transmission processing device 50. It is possible to drive the latching relay with the electric power that is supplied to the latching relay. Here, as the latching relay 20, one having a contact capacity of about 20 A is used.
