Pressure meter and pressure test method

Abstract

An embodiment of the invention discloses a pressure meter and a pressure test method. The pressure meter comprises a signal transmission module and a timing module. The signal transmission module can receive a signal for starting to detect a detection point to be detected, and meanwhile, clock signals enable time points corresponding to each pressure value to be stored to a storage module; and a data processing module processes the pressure value and the time points to obtain a test result. According to the pressure meter, a detection function of the pressure meter is started through the signal transmission module, measuring time of each pressure value is recorded through the timing module, and display is realized through a human-computer interaction interface, thereby realizing automatic control of the pressure meter, improving data integrity through record of the time points, realizing automatic recording, storage and processing of the data through the storage module, the data processing module and the human-computer interaction interface without manual record of the test data, preventing errors due to manual operation, and improving accuracy of the test result; and the automation degree is high.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a pressure gauge and a pressure testing method. Background technique [0002] Existing EMU brake valve tests use common air pressure gauges or use two air pressure gauges for comparison. Traditional barometers only have the basic function of measuring with a single data source, relying on manual reading, the accuracy is greatly affected by the level of operating skills. When special valves (for example, relief valves) need to compare two air pressure gauges for experimental testing, the accuracy is greatly affected by the skill level of the workers by manually reading the corresponding changes, and the efficiency is not high. It cannot be automatically written into the system, and it is difficult to complete data interaction. [0003] In the process of realizing the embodiment of the present invention, the inventor found that the existing pressure gauge needs to ...
