BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring control system capable of controlling a plurality of loads by one signal line by time-division multiplexing and transmitting control data to the signal line via an integrated unit. The present invention relates to a remote monitoring control device integrated with a plurality of devices.

[0002]

2. Description of the Related Art Conventionally, as a remote monitoring control system of this type, there is a system as shown in FIG. In the figure, a maximum of four loads L can be individually controlled by one control terminal 12. That is, a 2-bit load number is set in each control terminal device 12 in addition to the control address individually given to each control terminal device 12, and which load L is controlled by designating the load number. It is configured so that it can be selected. Similar to the control terminal device 12, the operation terminal device 11 has an operation address and a load number set therein, and a maximum of four operation switches S can be connected to one operation terminal device 11.

A plurality of operation terminals 11 and control terminals 12 are provided, and are connected to the transmission control device 10 via a two-wire signal line L _S. Since each operation terminal device 11 is set with an individual operation address and each control terminal device 12 is set with an individual control address, the transmission control device 10 uses the operation address and the control address. The operation terminal 11 and the control terminal 12 are individually recognized using the address.

The transmission control device 10 controls the signal line L _S by
The transmission signal V _S having the format shown in FIG. 9A 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 V _S , the address data (including the load number) AD for individually calling the operation terminal device 11 and the control terminal device 12, and the load L. Control data CD for controlling the transmission, checksum data CS for detecting a transmission error, and a signal return period WT which is a time slot for receiving a return signal from the operation terminal 11 or the control terminal 12.
Is a bipolar (± 24 V) time-division multiplexed signal consisting of
Data is transmitted by pulse width modulation (FIG. 9 (b)). In each operation terminal device 11 and each control terminal device 12, the transmission signal V received via the signal line L _S
To match the transmitted address data AD is preset action being address or control address by _S, it fetches control data CD from the transmission signal V _S, the monitoring data to the signal return period WT of the transmission signal V _S It is returned as a current mode signal (a signal emitted by shorting the signal line L _S via a suitable low impedance).

From the transmission controller 10 to the desired operation terminal 1
When transmitting data to 1 and the control terminal 12, the transmission signal V _S to the mode data MD as a control mode, the operating address or control address of the operation terminal 11 or the control terminal 12 as the address data AD Is transmitted and this transmission signal V _S is transmitted to the signal line L _S , the operation terminal device 11 or the control terminal device 1 matching the address data AD
2 receives the control data CD and returns the monitoring data during the signal returning period WT. In the transmission controller 10, the control data CD is the desired operation terminal device 1 depending on the relationship between the sent control data CD and the monitoring data received during the signal return period WT.
1 or the control terminal 12 confirms that the data has been transmitted.
Further, the control terminal device 12 outputs a load control signal for controlling the load L according to the received control data CD, and the operation terminal device 11 outputs a monitoring signal for performing an operation confirmation display of the load L according to the received control data CD. Is output. Here, the control terminal device 12 can receive a load monitoring input from the load L. Control terminal 12
Then, the monitoring data is generated based on the load monitoring input and is sent during the signal return period WT.

On the other hand, the transmission control device 10 always sends out the transmission signal V _{S in} which the mode data MD is in the dummy mode at a constant time interval, and the operation terminal device 11 causes the transmission control device 1 to operate.
When trying to transmit some information to 0,
An interrupt signal as shown in FIG. 9C is generated in synchronization with the synchronization signal SY of the dummy mode transmission signal V _S. At this time, the operation terminal device 11 sets an interrupt flag to prepare for the subsequent information exchange with the transmission control device 10. Transmission control device 10
Then, when the interrupt signal is received, the mode data MD is set to the interrupt polling mode and the transmission signal is transmitted while sequentially increasing the upper half bits of the address data AD (upper 4 bits when the address data AD is 8 bits). Then
In the operation terminal device 11 which has generated the interrupt signal, when the upper 4 bits of the address data AD of the transmission signal in the interrupt polling mode match the upper 4 bits of the operation address set in the operation terminal device 11, During the signal return period WT, the lower half bits of the operation address are transferred to the transmission controller 10
Return to. Since the transmission control device 10 collectively searches for 16 operation terminals 11 that have generated an interrupt signal, the operation terminals 11 can be found in a relatively short time. When the transmission control device 10 acquires the operation address of the operation terminal device 11 which has generated the interrupt signal in this way, the mode data MD is set to the monitoring mode, and the acquired address data AD
Is transmitted to the signal line L _S, and the operation terminal device 11 returns the information to be transmitted in response to this transmission signal in the signal return period WT. Finally,
The transmission control device 10 operates the operation terminal device 11 that has generated the interrupt signal.
A signal for instructing an interrupt reset is sent to cancel the interrupt flag of the operation terminal device 11. As described above,
Information transmission from the operation terminal device 11 to the transmission control device 10 is
This is completed by four signal transmissions (dummy mode, interrupt polling mode, monitoring mode, interrupt reset) from the transmission control device 10 to the operation terminal device 11. Transmission control device 1
When 0 wants to know the desired operating state of the control terminal device 12, it suffices to send a transmission signal using the mode data MD as the monitoring data.

As is apparent from the above-described operation, in the transmission control device 10, when the switch S provided in the operation terminal device 11 is operated, the switch S and the switch S are returned based on the operation data returned from the operation terminal device 11. The control data to be transmitted to the control terminal 12 to which the load L having the preset correspondence relationship is connected is generated, the transmission signal V _S including the control data is transmitted to the signal line L _S , and the corresponding control terminal is generated. Control data is transmitted to 12 to control the load L.

Therefore, the operation address and the control address also represent the types of the operation terminal device 11 and the control terminal device 12. To briefly summarize the above operations, if there is an operation input by the switch S to the operation terminal device 11,
When the transmission control device 10 transmits control data CD to the control terminal device 12 by returning the monitoring data corresponding to the operation input to the transmission control device 10, the control terminal device 12 outputs a load control signal to operate the relay 13. This means that the load L is controlled. Here, since the load monitoring input is given to the control terminal 12 by the operation of the relay 13,
The transmission control device 10 transmits monitoring data corresponding to the load monitoring input.
Then, the returned monitoring data is transmitted to the operation terminal device 11. The operation terminal 11 outputs a monitoring signal according to this transmission signal. The monitoring output is normally used to turn on and off the operation confirmation lamp, which is a light emitting diode.

By the way, the above-mentioned remote monitoring control system
Is called 1 system for 1 partition for management reasons.
Since it is arranged like this, it can be spread over multiple systems.

By the way, in the ordinary operation terminal device 11 and control terminal device 12, one operation address or control address is set, and conventionally, a mechanical switch such as a DIP switch is used. Although the operation address and the control address were set by using, the operation is troublesome with the mechanical switch. Therefore, recently, an address storage unit made of a semiconductor memory is provided to set the operation address and the control address. Is starting to appear. An external setting device is used to set an operation address and a control address in such an address storage unit.
Since four load numbers are added to each operation address or each control address, a setter for setting the operation address or control address can perform four circuits at a time (that is, load number It is possible to set the number of pieces).

In the integrated unit 14 as well, since it is necessary to set the control address and the operation address of the first terminal section 12a and the second terminal section 11a in association with each other, the address storage section 15 composed of a semiconductor memory. Is provided. Here, in order to set a control address and an operation address in the address storage unit 15, the operation terminal device 11
Since it is inconvenient to use a setting device different from the control terminal device 12 and the control terminal device 12, it is desirable to share the same setting device with the operation terminal device 11 and the control terminal device 12.

On the other hand, in the integrated unit 14 shown in FIGS. 10 and 11, one lower system B _{1 to} B ₄ can be connected to one upper system A. For example, each lower system B ₁ to B ₄ can be connected. if ₄ for attempting to control the control terminal 12 of each eight, 8 × 4 = 32 integrates the control address of the circuit component and operating the address unit 14
Need to correspond. The integrated unit 14 is provided with an address setting unit 16 for writing data from the setting unit into the address storage unit 15.
Since it has the same configuration as the address setting unit used in the control terminal 12 and the control terminal 12, the number of circuits that can be handled at one time is four, and as described above, the control address and the operation address for 32 circuits can be set. Requires the provision of eight address setting units 16. If such a configuration is adopted, there arises a problem that the cost is increased and the mounting space is enlarged.

The present invention has been made in view of the above reasons, and an object thereof is to increase the size and cost even when setting the operation addresses and control addresses of a relatively large number of circuits in the integrated unit. It is to provide a remote monitoring control device that can be suppressed.

[0015]

According to a first aspect of the present invention, the address data included in a transmission signal which has a control address set for each and is time-division multiplexed on a signal line and transmitted is the above-mentioned control.

Any one of the connectable signal lines and the operation terminal is connected to the upper signal line, and the remaining signal line connected to the control terminal is connected to the lower signal line. The integrated unit is connected between the signal line and the lower signal line and converts the transmission signal between the upper signal line and the lower signal line, and the integrated unit sets the control address used in the upper signal line.

A terminal unit, an address storage unit that stores a plurality of control addresses and operation addresses corresponding to each other, and a control address and an operation address are set in the address storage unit using an external setting device. When the address setting unit and the control address and the operation address are set in the address storage unit, the storage area of the address storage unit is divided into a specified number of control addresses and In which and a selection switch for selectively connected to address setting unit each divided region in the state where the action address is divided into storable size. According to this configuration, by providing the address storage section having the storage area of a desired size, the operation terminal connected to the upper signal line and the control terminal connected to the lower signal line are made many-to-many. Even though they are associated with each other, when setting a control address or an operation address in the address storage unit, the address storage unit is divided by using a selection switch and connected to the address setting unit, which is conventionally provided. It is possible to set a control address and an operation address in the address storage section without using a plurality of address setting sections by using the setter. That is, since one address setting unit can be shared for setting control addresses or operation addresses of multiple circuits, it is possible to prevent the integrated unit for multiple circuits from increasing in size and cost.

According to a second aspect of the present invention, in the first aspect of the invention, the address storage unit is a rewritable nonvolatile memory. According to this configuration, even if the power is cut off after setting the control address and the operation address, the control address and the operation address are not lost, and can be used in the original state when the power is restored. . Moreover, since the control address and the operation address can be electrically written and rewritten, it is possible to easily set the control address and the operation address according to the layout of the load in the field, and the load address. The layout can be easily changed.

According to a third aspect of the present invention, in the second aspect of the present invention, the address setting section receives the optical wireless signal including the control address or the operation address transmitted from the setting device, and A wireless signal receiving means for extracting a control address or an operation address from the optical wireless signal received by the light receiving element and writing the extracted address in the address storage unit. According to this configuration,
Since the optical wireless signal is used for writing the control address and the operation address in the address storage unit, wiring work and the like are not required when setting the control address and the operation address, and the setting work becomes easier.

According to a fourth aspect of the present invention, in the third aspect of the present invention, the address setting section separately receives an optical wireless signal including a control address and an optical wireless signal including an operation address. It is provided with an element. According to this configuration, since the light receiving element used for setting the control address and the light receiving element used for setting the operation address are separated, the control address and the operation address can be managed individually, and Since the signal line and the lower signal line are separately set, the possibility of erroneous setting is reduced.

According to a fifth aspect of the invention, in the first to fourth aspects of the invention, the selection switch is a rotary switch. This configuration is a preferred embodiment, and since the selection switch is a rotary switch, it is possible to clearly indicate which divided area of the address storage area is selected by comparing it with a dip switch or the like, and save space. Can be built in.
