Abstract

The invention discloses a low-voltage control cabinet computer control system comprising a controller, a signal input unit, a signal output unit, and a host computer. The signal input unit comprises multiple sampling signal inputs which are connected with the sampling signal input ends of the controller via sampling signal processing circuits. The signal output unit comprises multiple relays. The signal output end of the controller is connected with the relays via drivers. The controller is connected with the host computer via a serial interface. The signal input unit also comprises multiple manual control inputs. The signal output unit also comprises multiple indicating lamps. The signal output end of the controller is connected with the indicating lamps. The low-voltage control cabinet computer control system has beneficial effects of replacing conventional control elements by a computer system so as to greatly reduce components, decrease size, and save cost, simplify a complex control circuit, facilitate repair, support remote data transmission, and achieve remote networking.

Description

technical field [0001] The invention relates to a computer control system of a low-voltage control cabinet. Background technique [0002] The traditional low-voltage control cabinet control system is composed of control components such as time relays, intermediate relays, transfer switches, buttons, and indicator lights. Some control systems also include contactors, circuit breakers, fuses, and isolating switches of the main circuit as needed. and dual power supplies etc. The disadvantage of this traditional control method is that it uses many components, the control circuit is complex, and the cost is high. The more components used, the higher the failure rate, poor reliability, and complicated maintenance. In particular, the more control points, the more complex the control circuit. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a new type of computer control system for low-voltage co...
