Research And Development Of Electrically Controlled Water Distribution Which Is Injected With Seperated Layer Water Under Abnormal High Pressure Difference

The research content of abnormal pressure differential multi- layer sepearate injection electronic control of the water distribution system is to achieve Inoueennryou-underground communication in injection wells, by the underground control circuit detect the the underground temperature, pressure and other dynamic parameters to,meanwhile control the motor and transform the channel, Finally the feedback information is given to the Inoueennryou control computer.This paper mian work is the project of multi-point injection pressure differential abnormal electrical control distribution system, including following aspects:1.Research in-well wireless communication system,and analyse the feasibility of underground acoustic communication;2. Designed abnormal pressure differential multi-layer sepearate injection electronic control of the water distribution system, according to system requirement for the selection of related devices, design pressure sensor circuit, temperature sensor circuit, detailed discussion of motor control process, design motor control circuit, motor position detection circuit3. Complete the communication control chip choice, Finally, select American Microchip company's PIC18F1220 chip of PIC microcontroller series, detailedly introduce PIC18F1220 chip,design the whole system connection circuit;4. Use MCC18 compiler, write and debug the communication control program in MPLAB IDE integrated development environment;5. Completed the system laboratory testing .
