A Distributed Remote Real-time Pressure Measuring System Based on Wireless Communication Technology

With urgent requirements on the transient pressure test in the explosion field, the number of test nodes is increasing, which puts higher requirements on centralized management and control as well as process monitoring. A distributed measuring system, based on wireless communication technology, can manage and control all test nodes scattered in the testing area through a wireless network, realizing scatter operation, collaboration and centralized control, and thus is a key research point in today's distributed measuring field. Based on the basic principles of the distributed testing, this paper designs a wireless distributed measuring system used for pressure measurement of explosion fields. The central control can realize long-distance management, controlling and monitoring of many test nodes through a wireless local network, including the working parameter configuration of the each node in the testing preparation stage; the working state monitoring reset of each node in the waiting for explosion stage and so on; and the real-time transmission of the testing data.
