Electrical signal control device

Abstract

The invention discloses an electrical signal control device which comprises a first instrument installed on a steam engine control chamber instrument panel, and a second instrument installed on a control cabinet of an electric main control chamber. The first instrument comprises a first single-chip microcomputer and a first instrument power supply. The input end of the first single-chip microcomputer is connected with a first function button module, the output end of the first single-chip microcomputer is connected with a plurality of first LEDs, a plurality of first LED indicating lamps and a first buzzer, and the first single-chip microcomputer is connected with a first serial interface. The second instrument comprises a second single-chip microcomputer and a second instrument power supply. The input end of the second single-chip microcomputer is connected with a second function button module, the output end of the second single-chip microcomputer is connected with a plurality of second LEDs, a plurality of second LED indicating lamps and a second buzzer, and the second single-chip microcomputer is connected with a second serial interface which performs bidirectional communication with the first serial interface. The first single-chip microcomputer and the second single-chip microcomputer are respectively provided with a standby contact. The electrical signal control device has the advantages of simple and convenient use, high flexibility, complete functions, high stability, high reliability and convenient popularization and use.

Description

technical field [0001] The invention relates to an electrical signal control device. Background technique [0002] At present, in thermal power plants, thermal power plants, and self-contained thermal power plants composed of steam turbine generator sets, there is a certain distance between the steam turbine control room and the electrical main control room, so during the operation of the equipment, corresponding operations must be carried out. Signal contact. In the past, due to the limitation of technical conditions, the communication system usually consisted of optical nameplates and self-holding buttons, installed on the corresponding control cabinets, and connected by multi-core cables between the two places. Due to the heat dissipation problem in the structure of the light plate, the phenomenon of excessive heat and self-explosion of the bulb often occurs, and the bulb needs to be replaced frequently, which affects the normal operation of the system and increases the ...

Problems solved by technology

Due to the heat dissipation problem in the structure of the light plate, the bulb often explodes due to excessive heat, and the bulb needs to be replaced frequently, which affects the normal operation of the system and increases the workload of the maintenance workers.

With the rapid development of technology, some domestic instrument manufacturers began to gradually combine the original system scheme principles into a set of generator control signal devices, but this combination has not yet been able to integrate the system
