Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a t-co remote control and monitoring system using a time division multiplex transmission method.

[Background technology]

An example of the configuration of a remote control and monitoring system using a conventional time division multiplex transmission method is shown in FIG. In such a system, a plurality of monitoring input terminals (1) and negative MT ili control terminals (2) are connected to the main operating unit (
4) is connected. Each terminal (]) (2) has a unique terminal address, and when the address data included in the transmission signal from the main operation unit (4) matches the terminal address of the own station, the terminal for load control - The device (2) is the main operation section (
4) outputs a control output according to the control data, and the monitoring input terminal (1) returns monitoring inputs from input switches (5a) to (5c), etc. as monitoring signals to the main operation unit (4). . (5a) to (5C) are Irukasui Sochi,
The monitoring input to be sent back to the main operation section (4) is set. In addition, (6a), (6d), etc. are relay contacts operated by the control output of the load control terminal (2).
When the relay contacts (6a), (6d), etc. are turned on, the load (7a), (7d), etc. is driven by the commercial power supply (8), and the load is controlled by the input from the monitoring input terminal (1). The operation when controlling the terminal device (2) will be explained as follows. First, the main operation section (4) accesses the monitoring input terminal (1). That is, the address data included in the transmission signal is matched with the unique terminal address of the monitoring input terminal (1). At this time, the monitoring input terminal (1) returns a monitoring signal indicating that the input switch (6a) is on.

When the main operation section (4) receives the above-mentioned monitoring signal, the main operation section (4) uses the process registered in advance in the main operation section (4) to send a message to the load control terminal corresponding to the input switch (5a).
2), then find the address of the load control terminal (
2) Create the control data and load control terminal (2)
access. The load control terminal (2) accessed by the transmission signal from the main operation unit (4) turns on the relay contact (6a) according to the control eater, and turns on the load (γa) corresponding to the input switch (5a). On control. At this time, there is not only one load (7) that is oscill-off controlled in response to the operation of the input switches (5a) and (5b), etc.
There may be more than one.

The general method of accessing each terminal device (1) (2) by the main operation unit (4) is to access all the terminal devices (1) (2) sequentially and cyclically. A method may be used in which monitoring terminals (1) within a specific address range are accessed centrally in response to an interrupt signal from an input terminal (1).

By the way, in such a system, the terminal address of each monitoring input terminal (1) and the monitoring input terminal (1)
The load control terminal (
It has a control area storage unit (4a) that stores the correspondence relationship with the terminal address of 2), and by changing the storage contents of the control area storage unit (4a) in the main operation unit (4), each monitoring The address range of the load control terminal (2) that can be controlled by the input terminal (1) can be changed. Normally, the input terminal (5) of the monitoring input terminal (1) is mounted on the wall as a wall switch, and the load (5) corresponding to this input switch (5) is
7) is assigned as a lighting load in the same room as the above-mentioned wall switch, for example. However, whether or not the correspondence between the monitoring input terminal (1) and the load control terminal (2) is appropriate can be determined by visiting the site where the terminals (1) and (2) are installed. In many cases, it cannot be determined until the main operation unit (4) is used to set the control area storage unit (4a), but when operated on site, the correspondence may not be very good. In such a case, there is a problem in that it is necessary to return to the location where the main operation section (4) is installed and reconfigure the control area storage section (4a).

The person operating the monitoring input terminal (1) confirms that the access indicator α→ is lit, and then operates the monitoring input terminal (1).
The terminal address of the load control terminal (2) to be controlled is set by the data setting switch OB. While waiting in this state, the monitoring input terminal (1) is accessed again from the main operation section (4), and the terminal address set by the data setting switch (11) is displayed on the main operation section.

When the specified terminal address has been returned, the end code is set using the data setting switch 01), and after confirming that the access indicator light [f4] lights up (M+If), the changeover switch 03 is turned off. be. Note that from the time the main operation unit (4) receives the start code until the end code is received, the access interval of the main operation unit (4) to the monitoring input terminal (1) is determined by the TV setting switch.・Sochi 0]) should be set at intervals that allow enough time to operate.
