In the air-driven hydraulic pressure test method provided by the second embodiment, the air-driven hydraulic pressure test device in the first embodiment is adopted, wherein T1, T2, T3 and T4 are respectively 10 minutes, 20 minutes and 10 minutes, and the humidity difference between the air inside the first water tank 101 and the air inside the second water tank 102 can be reduced by keeping standing, so that the interference of the air humidity difference on the test can be reduced. The first air humidity sensor and the second air humidity sensor are arranged in the vertical direction, and in the first embodiment, the average value of the humidity of the upper, middle and lower positions is calculated, so that the air humidity in the first water tank 101 and the air humidity in the second water tank 102 can be obtained more accurately, and the air pressure values detected by the first air pressure sensor 104 and the second air pressure sensor 106 are more accurate due to the interference of the discharged air humidity on the air pressure.

Taking the single detection of the water pressure in the first water tank 101 as an example, the first distance sensor 105 and the second distance sensor 107 can respectively and accurately detect the liquid level in the first water tank 101 and the liquid level in the second water tank 102, so as to calculate the air volume in the space above the liquid level in the first water tank 101 and the air volume above the liquid level in the second water tank 102, the host 118 analyzes and calculates the values detected by the first air pressure sensor 104 and the first water pressure sensor 108, so as to obtain the water pressure value of the first water pressure sensor 108 in the pressure maintaining state (adding air pressure) and the water pressure value of the first water pressure sensor 108 in the non-pressure maintaining state (after the air pressure is removed after the third valve 119 is opened), the water pressure value in the pressure maintaining state is used for assisting in verifying the precision of the first water pressure sensor 108, and when the relation curve between the water pressure value in the pressure maintaining state and the water pressure preset in the host 118 is not correct, it is interpreted that the accuracy or sensitivity of the first water pressure sensor 108 is insufficient, i.e., the quality of the first water pressure sensor 108 is not qualified. After the pressure maintaining test, the reliability of the first water pressure sensor 108 is high, and the next test can be performed, and the test and the water pressure test in the second water tank 102 are performed in a cooperative detection mode, wherein the method for separately detecting the water pressure in the second water tank 102 is the same as the method for separately detecting the water pressure in the first water tank 101, and is not repeated.

The first water tank 101 and the second water tank 102 cooperatively detect, that is, the first valve 112 and the second valve 113 are opened simultaneously, the water pressure in the first water tank 101 and the water pressure in the second water tank 102 are kept consistent after standing, at this time, the value of the first water pressure sensor 108 and the value of the second water pressure sensor 109 are observed, if the difference between the value of the first water pressure sensor 108 and the value of the second water pressure sensor 109 is within a preset range, it is indicated that the accuracy of the first water pressure sensor 108 and the accuracy of the second water pressure sensor 109 are both high in reliability, otherwise, the smaller difference between the value of the first water pressure sensor 108 and the preset water pressure value is taken as a final detection value, for example, the difference between the water pressure value detected by the first water tank 101 and the preset water pressure value is smaller than the difference between the water pressure value detected by the second water tank 102 and the preset water pressure value, and the water pressure value detected by the first water tank 101 is taken as a final detection value.

As described in step S610, the test is finally performed in the non-pressure maintaining state, the third valve 119 and the fourth valve 120 are opened, and the average value of the water pressure value detected by the first water pressure sensor 108 and the water pressure value detected by the second water pressure sensor 109 in the tenth array is used as the detected water pressure value, where the detected water pressure value is the final detected water pressure value.

Adopt atmospheric pressure in this application, air humidity and water pressure three are synthesized and are compared, and adopt independent pressurize in proper order, cooperate pressurize (under the state of first water tank 101 and second water tank 102 intercommunication) and cooperate non-pressurize (under the state of opening third valve 119 and fourth valve 120), the required precision is by high to low, and through keeping stewing, reduce rivers to hydraulic interference, through the detection precision of air humidity and supplementary check-up first water pressure sensor 108 of atmospheric pressure and second water pressure sensor 109, obtain ultimate water pressure detected value, the problem that among the prior art water pressure detection process rivers influence water pressure detected value precision has been solved.
