Fault detection system and method for a concrete mixing plant

Abstract

The invention discloses a breakdown detection system and a method for a concrete mixing plant. According to the breakdown detection system and the method for the concrete mixing plant, an information obtaining device is used for obtaining an operation starting signal and an operation achieving signal sent from the equipment of the concrete mixing plant and generating into an operating production sequence; a breakdown detection device is used for comparing the operating production sequence with a preset operating standard sequence; when the error between the operating production sequence and the preset operating standard sequence is larger than a preset breakdown threshold value, the device is judged to be broken down. The breakdown detection system and the method for the concrete mixing plant can generate into the production sequence, dynamically compare the production sequence with the standard sequence, warns potential breakdowns and displays occurred breakdowns by working out the error between the production sequence and the standard sequence, enable the breakdowns to be conveniently judged and enable the production sequence to be visually observed.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a fault detection system and method for a concrete mixing plant. Background technique [0002] During the production process of the concrete mixing station, the start and stop of each equipment and the opening and closing of the material door are controlled by the control system or controller. For example, the controller is PLC, and the PLC controls when the equipment starts and stops and when the material door opens and closes. , and the length of the door opening time, the control sequence diagram of the mixing plant is formed by taking the time as the axis. The mixing station has the operation sequence diagram of each equipment, but in the actual production process, due to the poor production conditions of the mixing station and many uncertain factors, the control timing during actual production often has a certain deviation from the design timing. There is a ce...

Problems solved by technology

In the production process, a large amount of timing data and related production data will be generated. The efficiency of manual search is low, and the control timing has a certain tolerance range of error. Difficult to distinguish, not easy to find the fault location
