In static detonation tests, there are many physical parameters needed to be tested, sensors are placed in a large area, and safe area is far away, which bring many difficulties to the usual down-lead electronic measurement system and the storage measurement system. A wireless measurement system based on WI-FI is developed, which is composed of data acquisition instruments and wireless networking equipments. The data acquisition instrument has the functions of signal conditioning, data acquisition and storage, wireless communication, high precision synchronization, and etc. The wireless networking equipment supports the 802.11n/ac protocol with a high transmission power and a high gain internal antenna inside. The whole system can be monitored and controlled remotely and wirelessly. Furthermore, it has the advantages of direct measurement for multiple parameters,synchronous trigger and acquisition of multiple channels and multiple equipments, wireless data transmission in high speed, and distributed layout in large scale, which greatly improve the test efficiency. The proposed system has been applied to several explosive effect tests and its high reliability has been verified.
