Control device for multi-channel electromagnetic valve

Abstract

The invention provides a control device for a multi-channel electromagnetic valve. The device comprises an assembly part on a shell of the device as well as an internal circuit part. During an experiment, the multi-channel electromagnetic valve which is connected to the device via an electromagnetic valve insertion part is detected by a current sensor and relevant circuits at first; and if detection results are correct, an instruction sent by an external computer is received by a communication module, or functions such as control of actions of the multi-channel electromagnetic valve are carried out according to programs set in a CPU. During normal implementation of the experiment, an operation state of the device can be displayed by a liquid crystal display screen in real time; if an operation indication lamp displays a normal state, a signal collection insertion part can output a control signal of the multi-channel electromagnetic valve, so that the signal can be collected by collection equipment; and if the device works abnormally, a fault indication lamp flickers and a buzzer rings to send out a prompt. The device has the advantages that use requirements of multiple ground experiments in solid propulsion technologies can be satisfied; hidden safety dangers can be reduced; and safety and reliability of the experiments can be enhanced.

Description

technical field [0001] The invention relates to the technical field of solid propulsion, in particular to a multi-channel electromagnetic valve control device in the cold test, hot test and combined debugging test of the solid propulsion technology. Background technique [0002] In the process of solid propulsion technology research, testing is an indispensable link. Solid propulsion device tests mainly include ground cold tests and ignition hot tests, etc. Both cold tests and hot tests involve the application of electronic equipment, such as acquisition Analyze various signals, control the coordinated action of multiple solenoid valves, etc. At present, solid propulsion technology test equipment is constantly being updated to meet different test tasks. Whether the control device and acquisition device in the test can work stably is related to the success or failure of the entire test. Therefore, electronic test equipment or devices in solid propulsion technology The stabil...

Problems solved by technology

[0003] The original test equipment for controlling multi-channel solenoid valves is bulky and the built-in drive power is heavy; testers need on-site wiring, the operation is complicated, and the reliability is not high. Before the test, the equipment will not check whether the solenoid valves are connected correctly and in good condition , after a fault occurs, it takes a long time to troubleshoot the fault
