Electrical control system

Abstract

The invention discloses an electrical control system in the technical field of electrical device control. The electrical control system comprises an input unit; the input unit is connected with a data analysis unit in an electric output mode; the data analysis unit is connected with a PLC hierarchical control system in an electric output mode; the PLC hierarchical control system is connected with a communication unit and an automatic switching unit in an electric output mode; and an operator terminal and a local display terminal are both connected with a control printing circuit in an electric output mode. Through matched use between the operator terminal and the local display terminal, when a large electrical device is operated, operation and electrical device instrument reading can be both considered, fault classification notification and early warning state indication are realized, the control instruction information can be printed in real time, a distributed storage system is adopted, the information storage ability of the main system is greatly enhanced, and a historical information database and a real-time database are set, and query by the operator is facilitated.

Description

technical field [0001] The invention relates to the technical field of electrical equipment control, in particular to an electrical control system. Background technique [0002] The electrical control system is generally called the secondary control loop of electrical equipment. Different equipment has different control loops, and the control methods of high-voltage electrical equipment and low-voltage electrical equipment are also different. In equipment operation and monitoring, most of the traditional operating components, control appliances, instruments and signals can be replaced by computer control systems and electronic components, but there is still a certain range of applications in small equipment and local local control circuits . This is also the basis for the circuit to realize the automatic control of the microcomputer. [0003] Existing electrical control systems mostly use electrical control cabinets for centralized power supply, control, monitoring and mea...
