Realization of 4~20mA Current A/D Conversion Module in the Water Pollution Source Online Monitoring Instrument under the Remote Metrology

Abstract:

In order to improve the efficiency of water pollution source online monitoring instrument under remote metrology and reduce the intensity of labor operation. 3G technology has been used to connect the instrument with the client's network through the STM32 microprocessor and A/D conversion. Current A/D conversion and 3G module have been used to complete the testing data transmission. In order to get the data, the software of server and client has been programed. Field experiments show that the system is stable and reliable, which can effectively meet the demand of the measurement.
