Abstract

The invention provides a vacuum system field calibration method based on wireless transmission. The method includes the following steps: using one or more wireless vacuum gauges to measure the vacuumdegree at one or more positions in an environment to obtain vacuum data related to the vacuum degree of the environment; carrying out signal processing on the vacuum data to form a wireless signal suitable for wireless transmission; and receiving the wireless signal and inversely processing the wireless signal to obtain the vacuum data of the environment, so as to realize the monitoring of the vacuum degree of the environment. By using the method and the system of the invention, the technical advantages such as low cost, low power consumption, high transmission efficiency, simple software design and reliable machine communication stability can be achieved.

Description

technical field [0001] The present invention relates generally to the field of vacuum metering. More specifically, the present invention relates to systems and methods for vacuum-related monitoring of an environment. Background technique [0002] Vacuum metering has extensive and important applications in the aerospace industry or the nuclear industry. With the vigorous development of communication technology in our country, it has been rapidly applied in various industries. In the large-scale thermal vacuum test and vacuum heat treatment furnaces in the aerospace industry and in vacuum equipment such as high-energy physics accelerators, the online measurement of vacuum degree is an important environmental parameter. In addition, there are multiple parameters such as temperature, vibration, electromagnetic, voltage, current, and flow that need to be measured at the same time. This raises an important technical problem, that is, how to simplify the complexity of industrial...
