Description

technical field [0001] The invention relates to the technical field of data acquisition, in particular to a remote data acquisition device used for a pressure regulating device. Background technique [0002] At present, in the data acquisition devices used for pressure regulating devices on the market, the data acquisition module inside the data acquisition device is used as the main control unit to collect important parameters such as pressure, temperature and flow of the pressure regulating device, and through the external GPRS communication module, link To the server, periodically upload the data collected on-site, so as to realize the collection of on-site working parameters. The existing data acquisition device has low product integration and high cost. It is necessary to purchase an additional GPRS communication module. The design is complex and the cost is high, so it cannot meet the requirements of relatively high cost applications. During configuration, engineers n...
