Study And Design Of The Electric Current And Humiture Controller Which Is Monitored Remotely By Mobile Phone

Many control cabinets and power distribution cabinets need to monitor current value of the circuit. Some of them need to monitor humiture value of the cabinets to ensure the normal operation of equipment. Most of the monitoring electric current and humiture equipments are independent of each other in the market. They not only cost more money but also bad for maintenance of epuipment. Faced with these problems, this thesis designs a new type of equipment which can monitor electric current and humiture at the same time remotely. It has widespread application value.The equipment aims at collecting value of the electric current and humiture, displays the collected value through digital tube. It can be displayed on the mobile phone terminal in WIFI environment. Users can set the electric current and humiture safety limitation by the keys. The equipment lights the alarm lamp when the electric current and humiture exceed the safety limitation.The main contents in this thesis as follows:1. The application background, significance and present situation at home and abroad was summarized in the first part. This thesis also comes up with resrarch targets and content.2. According to the application environment of the monitoring instrument, this thesis analyses the demand of users, designs overall framework of the system.3. According to design idea of the system, the hardware system of electric current and humiture controller was built.(1)To contrast and select the chip of core device and humiture controller.(2)To draw the schematic diagram of each part, complete hardware system and realize the first generation prototype.4. According to demand and established hardware system of electric current humiture controller, embedded control code was developed to achieve the function of the controller.(1) The acquisition and display of electric current and humiture was completed.(2) To complete the set of electric current and humiture with buttons.(3) Alarm lamp was lighted when the electric current and humiture exceed safety limit.(4) Remote communication module program was developed to complete the remote monitering of electric current and humiture.5. PC software was developed to complete the remote monitoring of electric current and humiture controller.6. Mobile phone APP software was developed to complete the remote monitoring of electric current and humiture controller.STM32 series MCU is used for the core controller of the control system. The value of electric current and humiture was got through transformer and humiture senor. It can be displayed on digital tube. The paraments of the electric current and humiture can be set by four keys. The peripheral circuit of WIFI wireless module was built in this thesis, users can monitor the electric current and humiture by PC software and mobile phone APP software.
