Pre-mistake and mistake-proof detection device of anti-surge adjusting control system

Abstract

The invention relates to a pre-mistake and mistake-proof detection device of an anti-surge adjusting control system. The detection device comprises a DCS control system input and output interface, a valve position transmitter, a feedback signal cable, a first voltage comparator, a second voltage comparator, a valve positioner, a vibration detector, an air release pipeline, an anti-surge valve body, a control solenoid valve, a voltage comparator, a power signal cable, a temperature detection element and a control signal cable. The DCS control system input and output interface is arranged in anelectronic chamber of a safe area, the anti-surge valve body is installed on the air release pipeline, the valve position transmitter is fixedly connected with a butterfly valve plate output rod contained by the anti-surge valve body, the valve positioner is installed on the anti-surge valve body, and the control electromagnetic valve is installed on the anti-surge valve body. According to the scheme, the temperature and vibration detection elements are additionally arranged on site and a voltage abnormal change detection circuit is additionally arranged, timely early warning and advanced intervention are conducted on the fault degradation tendency of the control system before thorough paralysis, so that stable work of the control system is guaranteed.

Description

technical field [0001] The invention relates to a detection device, in particular to a fault prevention detection device for an anti-breath adjustment control system, which belongs to the technical field of electric instrument detection. Background technique [0002] The control and adjustment system is an indispensable element in the industrial automation environment. It is to realize the program set by the DCS or PLC to drive the action of the controlled object on site according to the instructions, and to control and adjust the pressure, temperature, flow and other industrial purposes. However, there is currently a lack of corresponding monitoring and detection means for the control signal cables, power drive cables, connector terminals, and control equipment contained in the control system itself. The resulting problem is that once a certain component or link in the control system fails, it will directly lead to the failure of the entire control system, out of control, a...

Problems solved by technology

However, at present, there is a lack of corresponding monitoring and detection methods for the control signal cables, power drive cables, connector terminals, and control equipment contained in the control system itself.

The resulting problem is that once a certain component or link in the control system fails, it will directly lead to the failure of the entire control system, out of control, and seriously threaten the stability of industrial production.
