Abstract
Abstract—with the urgent requirements on the transient pressure test in explosion field, the number of test node is increasing, which puts forward higher requirements on centralized management, controlling and process monitoring. The distributed measuring system based on wireless communication technology can manage and control all test nodes scattered in the testing area through wireless network, realizing scatter operation, collaboration and centralized control, and thus 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 the pressure measurement of the explosion field. The control central can realize a long-distance management, controlling and monitoring on many test nodes through the wireless local network, including the working parameter configuration of the each node in the testing prepared stage; the working state monitoring reset of each, node in the waiting explosion stage and so on; and the real-time transmission of the testing data.

There is large amount of test data to gather in an explosion, so to improve transmission efficiency, a WLAN-based distributed measurement system using a star network topologic structure that consists of a data management center, field test nodes, and communication network was established
Summary
In the damage effectiveness evaluation of a weapon system, the transient pressure of the shock wave is an important method to directly test the blast effect, which is of great importance to the study of damage effect and personal protection [1]. To better complete the data transmission and node control of the distributed testing of a recent explosion area, the researchers at home started to integrate wireless communication technology into the distributed testing design [4]. The system adopts Wireless LAN technology to connect all the testing nodes to the wireless local area network and realizes the monitoring, control and management in real-time, which makes it suitable for testing the complex field signal and competent for complex signal tests. There is large amount of test data to gather in an explosion, so to improve transmission efficiency, a WLAN-based distributed measurement system using a star network topologic structure that consists of a data management center, field test nodes, and communication network was established
