Saline-alkali soil aqueous salt dynamic Internet of Things synchronous automatic detecting system

The invention discloses a saline-alkali soil aqueous salt dynamic Internet of Things (IOT) synchronous automatic detecting system, comprising a lower computer information collection terminal and a server host computer system, and characterized in that the lower computer information collection terminal and the server host computer system are in communication connection through a GPRS-Internet network; the lower computer information collection terminal employs an intermittent power supply scheme, and receives instructions of the server host computer system to perform sensor power supply preheating, data collection and information transmission; after collection, the sensor automatically cuts power off to reduce the harm of electrochemical corrosion and prolong the service life of the sensor; after receiving the data uploaded by the lower computer information collection terminal, the server host computer system stores and analyzes the data. The system has the characteristics of simple and reliable structure, synchronous, automatic and stable information detection, reasonable cost and easy layout, and can be used for saline-alkali soil aqueous salt information detection, transmission and analysis display.
