Research And Design Of ZigBee Wireless Pressure Meter

With the development of digital wireless communication technology, the application of wireless data transmission is more and more widely, in the field of industry, wireless data acquisition and wireless data communication of a typical application. In the field of oil drilling, due to the changing environment, many oilfields are distributed in the wild, distribution, and for oil drilling industry instrumentation data are adopted the way of artificial patrol record. Manual record way faults obviously, big workload, low efficiency, easy to be affected by the weather, and geographical environment factors. As information technology in oilfield application gradually popular, wireless data communication technology also gradually obtained the application in the field of oil field.In order to change the way by manual record before work, improve the management level of oil field, improve work efficiency, this topic for oilfield pressure between the valve groups put forward a set of digital data acquisition application pressure data wireless transmission system. The core of the system is pressure wireless data acquisition device, the function of the device is to replace the traditional pointer type pressure gauge, pressure data by sensors, through the ZigBee wireless network transmission to the special wireless communication converter, the pressure of the converter will receive data remote transmission through GPRS cellular mobile communication network to the duty room, and displayed on the office computer.The device of control core by MSP430 single chip microcomputer with ultra-low power consumption characteristics, wireless communication part chose for wireless sensor network application launch ZigBee wireless communication technology, has the characteristics of low power consumption, high reliability, long-life li-ion battery power supply for the whole device.Device of in certain oilfield test site selection of the valve between groups, from the point of the actual test, the design scheme of wireless pressure operation of data acquisition device is stable and reliable, and can collect real-time pipeline pressure data between valve group, and the transmission of data to the office to monitor computer, has reached the design requirements.
