Abstract

PURPOSE:To perform control without requiring a central controller/monitor or full knowledge of operational sequence and prohibition items by producing a control command from each terminal controller/monitor and transmitting the control command to another terminal controller/monitor thereby filling the role of a central controller/monitor. CONSTITUTION:An input section 30e of a terminal controller/monitor 30 detects the ON operation of an electrical machinery to be controlled and monitored and provides a detection signal to a monitor information producing section 30f, which then produces a command word. A transmitting/receiving section 30a adds the self address stored in a self address memory section 30j to the command word which is then fed to a terminal controller/monitor 3A. The terminal controller/monitor 30 receives a 'response command' from the terminal controller/monitor 3A. When the counterpart address is identical to the address stored in the self address memory section 30j, the transmitting/receiving section 30a passes the command word to a control signal producing section 30c. The control signal producing section 30c produces a control signal for operating the electrical machinery to be monitored and provides the control signal to a drive signal output section 30d.

[Problems to be Solved by the Invention] The conventional power distribution equipment control and monitoring device as described above has the following problems.

(a) Even when building a small system, a central control and monitoring device was required, making the entire system expensive and requiring a large installation space.

(b) When preparing control and monitoring procedures for the central control and monitoring equipment, it was necessary to thoroughly understand the vast and complicated operating procedures and prohibitions regarding the operation of all connected power distribution equipment.

(1) Since the minimum unit of control and monitoring consists of contact inputs, relay contact outputs, etc., the central control and monitoring device controls and monitors each networked power distribution device using an algorithm that follows its own control and monitoring procedures. It is necessary to output commands, and therefore the number of control/monitoring procedures within the central control and monitoring device becomes enormous. This increases the processing time to complete one control/monitoring command, making the use of signal transmission lines extremely inefficient. It was bad.

(1) Since the self-address and the other party's address were fixed, it was not possible to flexibly respond to expansions and changes in the power distribution equipment control and monitoring system due to the addition of terminal control and monitoring devices.

(e) It was not possible to control and monitor various power distribution equipment using the 1M class terminal 11 control and monitoring equipment.

This invention was made to solve the above-mentioned problems, and it eliminates the need for a central control and monitoring device, eliminates the need for familiarity with operating procedures and prohibitions for controlling and monitoring various power distribution equipment, and is simple and simple.
