Design and Implementation of an Automatic Emulsion Dispensing and Remote Monitoring System Based on IoT Platform

In order to realize the automatic dispensing and remote monitoring of emulsions in the coal mine production process and improve the efficiency and safety of coal mine production, an automatic dispensing and remote monitoring system of emulsions based on the IoT platform was built. The APRUS X industrial network management adapter in this system is the upper computer of Siemens S7-200SMART PLC and the data transmission hub between the dispensing system and the MixIOT cloud platform, while the MixIOT cloud platform realizes the functions of data visualization and remote control terminal; the PLC acts as the control core and monitors the weight sensors, solenoid valves, DC brushless booster pumps, agitators and other equipment at the same time. The data collected by the sensors are uploaded to the cloud through IOT technology and combined with real-time data to realize automatic dispensing and remote control of emulsion. Meanwhile, remote monitoring is realized through Web page and apps, which is convenient for managers to monitor the production site in real time and realize intelligent production. There are 27 groups of liquid dispensing experiments, and the average relative error of emulsion concentration ratio obtained after 27 groups of tests is 4.8%, and the accuracy requirement meets the actual engineering needs. The research results are of great significance to promote the intelligent production of coal mines and the application of industrial IOT technology, and provide specific reference and references for the research and application in related fields.
