A programmable timing controller has been introduced to complete the experimental sequence control function. Programmable timing controller is used to control equipment related to the test timing, with an accuracy higher than+/-2ms. Adopting products from Nicolet Company in the United States, the entire system hardware is centrally arranged in the control cabinet, and the information exchange with the programmable controller is a passive contact. The channel parameters can be set and displayed through the human-machine interface, including the channel output start time, channel output duration, etc. The safety interlocking system is divided into two parts: software and hardware. The software part is included in the monitoring software, which automatically determines whether the conditions for the test are met based on the information obtained from the PLC by the monitoring software. The hardware part is composed of four parts: serial dry nodes, safety door locks, safety modules, and time current protection units. The serial trunk node is about to connect the auxiliary contacts of the equipment that needs to be interlocked with the operating circuit of the equipment that is restricted by the interlocking conditions, in order to achieve hardware interlocking between the equipment; The safety door lock adopts a safety lock system imported from France. Only when the safety conditions are met can the key be taken from the keybox of the control panel to open the door. If a door is opened, the test cannot be conducted, further ensuring the personal safety of the test personnel; The security module adopts the Modicon safety module module, providing another layer of hardware protection independent of the above parts; The time current unit is used to disconnect the system in a timely manner when problems are found during the testing process, ensuring equipment safety,
