An Encoder Detection System of a Tower Pumping Unit

Abstract

The invention discloses a tower type pumping unit encoder detecting system. The tower type pumping unit encoder detecting system comprises a PLC, a touch screen controller, a power supply and a cable, wherein the cable is connected with a pumping unit encoder. Four paths of high-speed acquisition ports are arranged on the PLC, connected with the cable of the pumping unit encoder, and used for acquiring pulse data of the A phase, the B phase and the Z phase of the encoder, and the PLC is communicated with the touch screen controller through an industrial data bus. Compared with an existing detecting device, the tower type pumping unit encoder detecting system is portable in design, interfaces are customized, the plug and play function is achieved, a large amount of disassembly, assembly and aloft work is avoided, an instrument display interface is simple, a conclusion can be directly acquired through one-button operation, all analysis, calculation and judgment are completed by professional software, the requirement for quality of operation staff is low, detecting speed is high, state judgment is accurate, and due to specific functions, the tower type pumping unit encoder detecting system is suitable for encoder detection in the whole production and debugging processes of a tower type pumping unit control system and convenient and quick to use.

Description

technical field [0001] The invention relates to an encoder detection device, in particular to a tower type pumping unit encoder detection system. Background technique [0002] At present, the pulse counting encoder is mostly used as the state feedback element in the tower pumping unit, and the failure of the encoder will cause the abnormal operation of the control system of the pumping unit. The commonly used detection method is to run the pumping unit to move the sucker rod for a certain distance. During this process, an oscilloscope or other special pulse counting device is used to collect data, and then the designer of the pumping unit control system conducts data analysis to determine whether there is a problem. . Then according to the analysis results, or judge that the encoder is damaged, replace it, or calibrate the stroke coefficient of the control system software. [0003] The conventional detection method of the tower pumping unit encoder has the following defect...

Problems solved by technology

[0003] The conventional detection method of the tower pumping unit encoder has the following defects: First, due to the mechanical structure of the pumping unit, there are a lot of high-altitude operations in the conventional detection method, which has certain safety hazards; second, professional and technical personnel are required for data collection , analysis, higher personnel quality requirements, increased product maintenance costs; third, the encoder failure will directly cause the abnormal operation of the entire control system, but there may be many reasons for the abnormal operation of the system, which are highly concealed and have no obvious features , the conventional detection method has no positioning means, and can only be checked one by one
