Mini intelligent controller for vacuum eliminator

Abstract

The invention discloses a mini intelligent controller for a vacuum eliminator. The controller is mainly composed of an input unit, a CPU control unit, a storage unit, a communication interface, a liquid crystal screen and an output unit, wherein the CPU control unit is connected with the input unit, the storage unit and the output unit. The input unit is connected with a primary water level sealing detection unit, a secondary water level sealing detection unit, a negative pressure monitoring unit, an electric execution unit and a fault detection unit to collect information including the primary water level, the secondary water level, the negative pressure, electric execution information and fault information of the vacuum eliminator and transmit the information to the CPU control unit accurately and timely. The mini intelligent controller of an integrated structure is small in size, complete in functions, accurate in control, timely in motions, stable in performance and high in adaptability, can conveniently control and monitor the vacuum eliminator in a full-automatic manner, is highly practical, and has high popularization values.

Description

technical field [0001] The invention relates to the technical field of electrical control, in particular to a micro-intelligent controller for a vacuum eliminating device. Background technique [0002] At present, the vacuum elimination devices used in the direct serial water supply mode on the market include mechanical and electric types. Mechanical vacuum elimination devices are more and more popular due to problems such as poor sensitivity, low reliability, large volume, heavy weight, and inconvenient installation. Therefore, most of the vacuum elimination devices adopt electric structure, but the protection function of the existing electric vacuum elimination devices is not satisfactory, and there is no dedicated controller, and its control is often completed through the control cabinet. There are slow response, distorted information, inconvenient professional control and management, and low safety and reliability. When the control cabinet fails, it will affect the norma...
