Liquid level control device and data processing

Abstract

The invention relates to a liquid level control device and data processing. A power supply unit is connected with a main CPU (Central Processing Unit) control unit, a display control unit, a switch-in and switch-out unit, an analog quantity unit and a measuring and protecting unit through a link unit, wherein the main CPU control unit, the display control unit, the switch-in and switch-out unit, the analog quantity unit and the measuring and protecting unit are communicated through a serial bus according to the default protocol, and the power supply unit is connected with other units through link units for providing a working power supply for the liquid level control device. The liquid level control device and the data processing overcome the fault of the traditional liquid level control system, are of an independent modular design, are reliable in performance, bring convenience for maintenance, have a remote control function, and can realize that a main serial port of the main CPU control unit is remotely controlled; due to the continuous self detection of hardware and software, real-time measurement, intelligent control and bus communication are integrated into a whole, and an effective protection effect is achieved on a water pump and other relevant equipment in the industrial production life.

Description

technical field [0001] The invention relates to a liquid level control device and data processing, which integrates real-time measurement, intelligent control and bus communication, controls the liquid water level in industrial production and life, and can realize the protection of related equipment such as water pumps. It belongs to the technical field of electric power system intelligent control. Background technique [0002] Most of the existing liquid level control devices use simple sensors and auxiliary equipment to control the water pump to realize the liquid level control function. Most of them are control devices like PLC, but the cost of such a structure is huge, and the control The speed and accuracy cannot be well guaranteed, and there is no effective protection function for the water pump on site, so it can no longer adapt to the increasingly strict functional requirements in industrial production and life. The existing liquid level controller has complex logic...
