A testing system conforming to the standard GB/T 19155—2017 for the hoist used for temporarily installed suspended access equipment was designed. The system includes the host computer unit, lower control unit, sensors and data acquisition unit, mechanical structure unit. The main control program was developed by using Visual Basic language and the cooperative control method between the host computer software and the PLC was proposed. The status of PLC ports were monitored in real time and the PLC internal auxiliary relay channels’ value could be changed by the software to control output in order to perform different detection processes according to the testing items and parameters set by the inspector; the test data was stored in the MySQL database and the detection report was automatically generated. The results show that the designed system is highly automated, stable and reliable.
