Problems solved by technology
[0005] 1. The versatility is not enough, and the function is relatively single. It is only suitable for a single type of pressure measuring instrument such as a pressure sensor with a voltage output.
[0006] 2. The standard is solidified in the system, the cost is high, the measurement range is limited and the scalability is not enough
[0007] 3. The detection process setting and data processing method are mainly for the convenience of production. They are not based on the national verification regulations, and the certificate report cannot be automatically generated, which is not conducive to the application of laboratory measurement and detection.

Embodiment Construction
[0024] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0025] Example figure 1 , figure 2 with image 3 As shown, this embodiment provides an automatic pressure detection device, which includes a host computer, a data acquisition card, multiple signal communication cables and standard instruments. The data acquisition card is built in the host computer, and the signal communication cable interface is divided into two types: GPIB and RS232, including one GPIB data cable and four RS232 data cables. The standard instrument adopts an independent setting method and is not integrated with the automatic pressure detection device. set up.
[0026] Two databases are set in the host computer, one is the basic information database, which mainly stores the communication port settings, control functions and reading functions of the standard device and the communication port settings and reading functions o...

The invention provides a pressure instrument automatic detection device and detection method thereof. The pressure instrument automatic detection device includes a computer host, a data acquisition card, and a standard instrument, the computer host controls the standard instrument to detect the instrument to be detected through the data acquisition card and performs the data transmission, the computer host is provided with a basic information database and a process control database, and the basic information database stores the communication port setting and control functions and the reading function of the standard instrument and the communication port setting and reading functions of the instrument to be detected. The pressure instrument automatic detection device is wide in applicability, the system doesn't force the integration of the standard instrument, the cost is low, the system extension property is good, the automatic detection device is suitable for the instruments on the present market, and for the further marketing instruments, the device provided can support the instruments only if the instruments have unified data ports, the device also can support electronic and flow instruments, the system has the self-checking function in operation, the immediate warning can be sent to ultra-poor instruments, and the waste of a lot of detection time can be prevented.
Description
technical field [0001] The invention belongs to the technical field of measurement and testing, in particular a universal testing device suitable for automatic testing of various types of pressure measuring instruments in a laboratory. The invention also provides a testing method using the testing device. Background technique [0002] Pressure measuring instruments such as pressure sensors, pressure transmitters, pressure controllers, and digital pressure gauges are widely used in aerospace, remote sensing measurement, environmental monitoring, medical equipment, and industrial production to measure pressure values in the environment. It is a very important control measuring instrument, and its accuracy and reliability directly affect the performance of the measuring device. In order to ensure that the pressure measuring instruments in actual use can accurately transmit information, they need to be verified or calibrated regularly according to the national verification reg...
