Problems solved by technology

[0004] The domestic detection system can only initially realize the automatic collection and processing of data. The pressure control is mainly manual control, which cannot realize automatic pressure control. The pressure fluctuation range is too large during the test and cannot be accurately controlled; the gas consumption data is obtained by reading the flow meter The number of scales and the method of recording environmental conditions on site are determined by manually calculating the gas consumption at a certain point in the data based on the measured ambient temperature, humidity, local air pressure and the scale number of the flowmeter, and the final gas consumption needs to be determined by averaging the values ​​at several time points; The calculation speed of the data processing system is relatively slow, and the system only has the data input terminal to process the collected data, but only passively accepts the collected data, and cannot realize intelligent control
The whole test process is inefficient, the data accuracy is poor, and the real-time performance is not strong
