DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relay terminal used for a remote control monitoring system.

[0002]

2. Description of the Related Art FIG. 43 shows a basic schematic configuration of this remote control monitoring system. In this conventional example, a control terminal 1 and an operation terminal 2 are connected to two signal lines 3. The operation terminal 2 and the control terminal 1 are connected to the transmission unit 4, and the operation terminal 2 and the control terminal 1 are respectively set with respective addresses. The transmission unit 4 controls the operation terminal 2 and the control terminal 1 by the address. Recognize individually. The operation terminal 2 includes switches SW1... And transmits an interrupt signal generated by operating the switches SW1. Upon receiving the interrupt signal, the transmission unit 4 searches for the operating terminal 2 requesting the interrupt, and further sends the searched operating terminal 2 to the control terminal 1 whose correspondence is set in advance by an address. The control data is transmitted. In the control terminal 1 receiving the control data, the connected magnetic holding type latching relay 5 is switched to the switch SW1.
.. Are driven in accordance with the operation of the point, and the load connected to the power supply is turned on or off through the main switching contact of the relay 5.

[0003] Here, the transmission unit 4 sends out a time division multiplexed transmission signal (hereinafter referred to as a transmission signal) Vs in the format shown in FIG. That is, control for controlling the synchronization signal SY indicating the start of signal transmission, mode data MD indicating the mode of the transmission signal Vs, address data AD for separately calling the terminals 1 and 2, and the load (relay 5 in FIG. 43). A bipolar (± 24V) time-division multiplexed signal comprising a data CD, checksum data CS for detecting a transmission error, and a return signal return period WT which is a time slot for receiving return signals from the terminals 1 and 2. Yes, data is transmitted by pulse width modulation (FIG. 44B). When the address data AD transmitted by the transmission signal Vs received via the signal line 3 matches the preset address, the terminals 1 and 2 fetch the control data CD from the transmission signal Vs and transmit the control data CD from the transmission signal Vs. The data is returned as a current mode signal (a signal transmitted by short-circuiting the signal line 3 via an appropriate low impedance) during the signal return period WT of Vs.

When data is transmitted from the transmission unit 4 to desired terminals 1 and 2, the mode data MD is set to the control mode, and the address of the terminals 1 and 2 is set to the address data A.
D, and transmits the transmission signal Vs to the signal line 3, the terminals 1 and 2 corresponding to the address data AD receive the control data CD and the control data C
A signal in which a parity bit is added to D is used for a signal return period WT.
Reply to. The transmission unit 4 confirms that the control data CD has been transmitted to the desired terminals 1 and 2 by matching the transmitted signal with the received signal in the signal return period WT. The control terminal 1 and the operation terminal 2 perform control operations according to the received control data CD.

On the other hand, the transmission unit 4 always sends the transmission data Vs to the dummy address or to the addresses of all the connected terminals at regular time intervals with the mode data MD in the dummy mode or in the constant polling mode. When the terminals 1 and 2 try to transmit some information to the transmission unit 4, they are synchronized with the synchronizing signal SY of the transmission signal Vs during the dummy mode or polling, and the interruption signal as shown in FIG. Generate. At this time, the terminals 1 and 2 set the interrupt flag to prepare for the subsequent information exchange with the transmission unit 4. When receiving the interrupt signal, the transmission unit 4 sets the mode data MD in the interrupt polling mode and transmits the data while sequentially increasing the upper half of the address data AD (the upper 4 bits if the address data AD is 8 bits). In the terminals 1 and 2 that transmitted the 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 replaced with the upper 4 bits of the address set in the terminals 1 and 2. When they match, the lower half bits of the address are returned to the transmission unit 4 during the signal return period WT. in this way,
The transmission unit 4 sets the terminals 1 and 2 that generated the interrupt signal to 1
Since the six terminals are collectively searched, the terminals 1 and 2 can be found in a relatively short time. When the transmission unit 4 acquires the addresses of the terminals 1 and 2 that generated the interrupt signal,
The mode data MD is set to the monitoring mode, and a transmission signal having the acquired address data AD is transmitted to the signal line 3, and the terminals 1 and 2 return information to be transmitted in the signal return period WT. . Finally, transmission unit 4
Sends a signal instructing an interrupt reset to the terminals 1 and 2 that have generated the interrupt signal, and releases the interrupt flags of the terminals 1 and 2. As described above, information transmission from the terminals 1 and 2 to the transmission unit 4 is performed by four signal transmissions from the transmission unit 4 to the terminals 1 and 2 (dummy mode, interrupt polling mode, monitoring mode, Reset). When the transmission unit 4 wants to know the desired operation state of the terminals 1 and 2, it is only necessary to transmit a transmission signal using the mode data MD as monitoring data.

In the transmission unit 4, when the switch SW1 provided on the operation terminal 2 is operated, the correspondence with the switch Sb is determined based on the monitoring data returned from the operation terminal 2. It generates control data to be transmitted to the preset control terminal 1, transmits a transmission signal Vs including the control data CD to the signal line 3, and transmits the control data CD to the corresponding control terminal 1. By driving the relay 5 of the load number corresponding to the switch SW1 included in the control data CD, and turning on or off the main switching contact, the load is turned on or off. When another operation switch SW2 provided on the operation terminal device 2 is operated, an interrupt signal is transmitted in the same manner as when the switch SW1 is operated, and the address is transmitted in response to the interrupt polling of the transmission unit 4. A reply is sent, and the operation data of the operation switch SW2 is returned to the transmission unit 4 as monitoring data in response to the access of the interrupt request monitoring from the transmission unit 4.

After the interrupt processing, the transmission unit 4 accesses the corresponding control terminal 1 and transmits the control data CD corresponding to the load number corresponding to the switch SW1. When receiving the control data CD in the standby state, the control terminal 1 drives a relay (not shown) corresponding to the load number of the control data in the same manner as described above.

Here, for example, 4
If four load numbers can be set, four switches can be controlled and driven by four switches, and in the case of FIG. 43, four relays 5 can be driven.

The control terminal 1 returns monitoring data indicating the operation state of the relay 5 to the transmission unit 4, and the transmission unit 4 transmits the monitoring data to the corresponding operation terminal 2 based on the monitoring data. On the other hand, the operation terminal 2 that has transmitted control data CD for turning on / off the operation monitoring LED 1 or LED 2 attached to the switches SW1... Corresponding to the load number of the relay 5 and received the control data CD The operating state of the corresponding relay 5, that is, the on or off state, is displayed by turning on or off the operation monitoring LED 1 or LED 2 attached to the switch of the corresponding load number based on the control data.

In the remote monitoring and control system shown in FIG. 43, each terminal 1, 2,
Of each terminal device 1, 2 by rectifying the multi-polar transmission signal Vs in each terminal device 1, 2.
It is designed to obtain the operating power inside. On the other hand, the relay 5 obtains power from the external transformer 6.

[0011]

As described above, in the control terminal 1, since the power for driving the relay 5 is obtained by the transformer 6, the control terminal 1, the relay 5 and the transformer 5 are separated. However, when these are arranged in the distribution board, there is a problem that securing a mounting space and connecting wires for connecting them are complicated.
