Problems solved by technology
Due to the large number of plugs for the input and output cables of the connector, there are many manufacturers and specifications of the plugs, and some plugs do not have the function of blind insertion. In the process of manual disassembly and assembly of the plugs, there may be problems of wrong connection and improper insertion, resulting in signal failure. decline in quality
Once a problem occurs, it takes a lot of time and manpower to troubleshoot the fault, reducing work efficiency

The invention belongs to aero-engine testing technology, and relates to a device for switching between an analog temperature measurement and control system and a digital temperature measurement and control system. The device is characterized in that a change-over switch unit (6) which is a six-way switch consisting of six double-pole double-throw switches. The invention proposes the device for switching between an analog temperature measurement and control system and a digital temperature measurement and control system, omits the work of manually dismounting a plug, conveniently and rapidly realizes switching between the analog temperature measurement and control system and the digital temperature measurement and control system, completely eradicates the problems of wrong connection and not-in-place insertion and connection due to manual dismounting of the plug, ensures signal quality, and improves work efficiency.
Description
technical field [0001] The invention belongs to the testing technology of aero-engine, and relates to a conversion device of an analog temperature measurement and control system and a digital temperature measurement and control system. Background technique [0002] Some of the current turbofan engines use an analog temperature control system, and some use a digital temperature control system. During the test run of the turbofan engine, it needs to be completed by manually disassembling the plug according to the different types of the temperature control system of the turbofan engine. Conversion of analog temperature control system and digital temperature control system. Due to the large number of plugs for the input and output cables of the connector, there are many manufacturers and specifications of the plugs, and some plugs do not have the function of blind insertion. In the process of manual disassembly and assembly of the plugs, there may be problems of wrong connection...
