A trigger acquisition control method for explosion effect wireless test network

Abstract

The invention relates to a trigger acquisition control method for an explosion effect wireless test network. By setting a satellite receiver module in the wireless test equipment in the wireless test network, the precise positioning of the measuring point and the high-precision time synchronization between the equipment can be realized; in the wireless test The LORA wireless communication module is set in the wireless test equipment of the network, and the wireless remote transmission capability based on the LORA standard can be used to realize the long-distance ultra-low delay (only delay electromagnetic wave propagation time) communication of the equipment in the network; the broadcast notification method based on LORA is adopted, Reliable triggering of multiple devices in the network can be realized; the trigger control technology that determines the trigger delay based on the distance between computing nodes can be used to realize the effective collection of signals at the measuring points. The invention can ensure reliable triggering and effective data collection of a plurality of wireless testing devices within a large range of explosion effects.
