Problems solved by technology
However, the air conditioner in the rescue cabin is only in operation when a mine disaster occurs, and it is not in operation for a long time at other times, which is likely to cause damage to parts. Regular diagnosis of air conditioning system failures is very important
When the air-conditioning system fails, the number of faulty components and fault sources cannot be determined, so using existing instruments to diagnose air-conditioning system faults requires complicated steps, high requirements for the test environment and many and precise instruments
It is also difficult to self-adaptively diagnose the faults of the system using the traditional blind separation algorithm

The invention discloses a blind-separation-technology-based detection system for diagnosing a CO2 air conditioner fault of a rescue capsule. The system comprises a detection system body consisting of a vibration signal analysis module, a noise signal analysis module, a signal acquisition module, a control module, a storage module, an intelligent fault self-diagnosis module, an alarm module, an underdetermined blind separation calculation module, an underdetermined blind separation experiment module and a display module. The output terminals of the vibration signal analysis module and the noise signal analysis module are connected with the input terminal of the signal acquisition module electrically; the output terminal of the signal acquisition module is connected with the input terminal of the control module electrically; and the output terminal of the control module is connected with the input terminals of the storage module and the intelligent fault self-diagnosis module electrically. According to the invention, compared with the traditional diagnosis fault device, the provided system for diagnosing a CO2 air conditioner system fault based on blind separation is verified to have advantages of low testing requirement, reduced testing device number, and reliable testing.
Description
technical field [0001] The invention relates to the technical field of air-conditioning fault detection systems, in particular to a method for diagnosing rescue cabin CO based on blind separation technology. 2 Air conditioner fault detection system. Background technique [0002] Mine rescue cabin air conditioning is an important part of the life support system of the mine rescue cabin. There are currently several types of mine rescue cabin air conditioning technologies: ice storage refrigeration, electric anti-riot air conditioning refrigeration and high-pressure gas expansion refrigeration. Ice storage refrigeration requires an external power supply, and the maintenance costs are usually high, and the power supply must be cut off in the event of a mining disaster. Electric anti-riot air-conditioning refrigeration must be equipped with large-capacity batteries or external high-power power supply, which may easily cause gas explosions in coal mines, and at the same time comp...
