Abstract

The invention discloses an OPC (OLE for process control) based electromagnet performance test system. The system comprises a data acquisition unit, a program control power source, a core control board, a control PC (personal computer) and a remote monitoring PC. The output end of the data acquisition unit is connected with the core control board; the program control power source is connected with an electromagnet and the core control board; the core control board is connected with the control PC through a serial bus. The control PC is connected with the remote monitoring PC through a network interface via the OPC function. The data acquisition unit acquires pressure and displacement signals of the electromagnet in real time; the program control power source acquires voltage and current signals and transmit them to the core control board; the core control board processes the acquired data and transmits it to the control PC; the control PC displays, stores and prints test results according to the data input by the core control board; thus, automatic testing of electromagnet performance is achieved, and test efficiency and test precision are greatly improved.

Description

technical field [0001] The invention relates to an OPC-based electromagnet performance testing system. Background technique [0002] At present, the application of electromagnets has penetrated into many engineering automation fields, and the test scheme for its performance has gradually developed from the traditional "sensor + data record" mode to a semi-automatic test system based on computer technology. However, due to the unreasonable design of the test scheme or hardware unit, the system function is too simple, the degree of automation is not high, or the system structure is complex, the test accuracy is not high, and remote control cannot be realized. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides an OPC-based electromagnet performance testing system with simple structure, high testing efficiency and precision, high degree of automation, and capable of remote monitoring. [0004] The techni...
