Research Of Drilling Engineering Monitoring System Based On Embedded Platform And WSN

During the development of petroleum and natural gas, drilling well is the one of most important processes, and the safety is the most important element in the drilling engineering. Though there is rigorous drilling operating criterion, the drilling accidents has happened frequently. Analyzing the causes of the drilling accidents, the dominating reasons are that not finding the symptoms of the accidents in time and not resolving them exactly, so there are multifarious drilling monitoring systems attempting to deal with the problem, but most of them utilize oversimplified processor or IPC as the controller, use data bus to connect the sensors with wires, which resulte in unskillful system construct, complicated installation, intricate operation and costliness, so as to apply broadly hardly.In order to solve the problems of drilling monitoring system, the author has designed a drilling monitoring system based on embedded platform and WSN. Field controllers contain field server and field client; the controllers are based on ARM-Linux platform and the HMI has programmed with Qt/Embedded. Remote client controller is IPC, HMI has programmed with VB. The data requisition and control of the system are completed in WSN. According to the environment of drilling field, tree-type wireless network is set up, ZigBee protocol is used to marshal data and actualize control.Field server connects with the coordinator node of WSN by UART, the controller can achieve the core functions of the system. Field server extends field client with RS485 and extends remote client by Ethernet. When three controllers are used, the field server is used to monitor drilling state and alarm, the field client is used to auto-grout or monitor drilling parameters, the remote monitoring and controlling system can storage drilling parameters, data demand and export forms. The system can be installed and configured easily with WSN, based on ARM-Linux platform so as to compact system structure and high performance with low price. It is convenient for users to choose because of three controllers, set up perfect alarm model to ensure the safety of drilling well, and it offer great help for the operators and engineers.
