Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a terminal device for setting pattern control data for collectively pattern controlling a plurality of loads in a remote monitoring control device.

[Prior Art] Conventionally, a central control unit accesses a monitoring terminal device for monitoring a switch and a control terminal device for controlling a load, time-division multiplex-transmits monitoring data and control data, and responds by operating a switch. There was a remote monitoring and control device that controlled the load remotely. By the way, in such a remote monitoring control system, when performing pattern control of a plurality of loads by a pattern control switch at a time, it is necessary to have a device for setting the pattern control data corresponding to each pattern control switch. Provided near the control switch is a pattern setting terminal device in which a large number of switch monitoring terminals for individually controlling loads (each set a unique address corresponding to the load controlling terminal) are arranged. The control data to be controlled by the switch operation and the selection data (unique address and load number) of the load connected to the control terminal are sequentially input to set the pattern control data.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional example, when a large number of loads exist, a large number of monitoring terminals corresponding to the control terminals to which the respective loads are connected. The pattern setting terminal device must be integrated to form the pattern setting terminal device, and there is a problem that the configuration of the pattern setting terminal device becomes complicated and large, and the cost increases. Therefore, by appropriately changing the unique address by the address setting switch of one switch monitoring terminal, it can be used as a plurality of switch monitoring terminals, and the pattern control data can be sequentially changed by the address setting switch. It is also possible to enter. However, since the address setting switch provided in the conventional monitoring terminal is not operated much except during construction, it is formed by a mechanically weak small dip switch. If it is frequently operated when setting, there is a problem that a failure is likely to occur. In addition, the address setting switch composed of this DIP switch is arranged at a position on the back or side of the terminal case that is difficult to operate so as not to be erroneously operated, so that the setting operation of the pattern control data is troublesome. was there.

The present invention has been made in view of the above points, and an object of the present invention is to reduce the size and cost, to prevent a failure, and to easily set the pattern control data. Another object is to provide a terminal for pattern setting.

[Means for Solving the Problems] A pattern setting terminal of the present invention is a signal for a central control unit, a monitoring terminal for monitoring a switch with a unique address set, and a control terminal for controlling a load. Connect with wires,
It is a terminal device that sets pattern control data for collectively pattern controlling multiple loads in a remote monitoring control device that accesses each terminal device from the central control device and transmits monitoring data and control data by time division multiplexing. A load selection section in which a load selection switch for selecting a plurality of loads connected to the control terminal is arranged, and a predetermined number of slide switches for inputting each bit data of the unique address of the control terminal. The address setting section with the address setting switch is lined up on the front of the terminal case,
The load which is collectively controlled by the load selection switch and the address setting switch is sequentially set and the pattern control data is input.

[Operation] The present invention is configured as described above, and in a pattern setting terminal for setting pattern control data for collectively pattern controlling a plurality of loads, a plurality of terminals connected to the control terminal are connected. Address selection section in which a load selection switch for selecting the load of the control terminal and a set number of slide switches for inputting each bit data of the unique address of the control terminal are input in the address setting section. Is installed on the front of the terminal case, and the pattern control data is input by sequentially setting the loads collectively controlled by the load selection switch and the address setting switch. The configuration is simpler and smaller than the conventional pattern setting terminal device formed by using a large number of monitoring terminals. In addition, the cost can be reduced and the address setting switch that sets each bit of the unique address is set with a mechanically stronger slide switch than the DIP switch, so it is operated frequently. Failures are less likely to occur when setting the pattern control data, and since the load selection switch and address setting switch are also provided on the front of the terminal case, the pattern control data setting work can be done easily. .
