The Research Of Delay Related Sound Trigger And Remote Monitoring Technology

The detective instrument of high-precision is taken and distributed in different testing points, which would test the weapon whether it could complement the requirement of checking standard according to the instrument of high-precision in the weapon proving range of routine testing. The uniform trigger signal which is distributed from several testing equipments in the range can obtain the accurate and real-time information of bullet to evaluate performance index of the weapon in testing. The method of delaying wave filtering is proposed in order to complement the above issue. The voice equipment of trigger signal is equipped in the front of gun, which would offer the real-time and accurate trigger signal according to relay system of trigger network in the weapon testing. According to the remote observed technique, the testing equipment status and trigger situation or delay time are controlled in the weapon giving range.The method of delaying wave filtering is designed to capture the accurate information of bullet, which is the key work in this paper. The specific work will be described as bellows.(1)The model system is built by that the echoed signal is processed by the method of delaying wave filtering, which based on the analysis of gunpoint information and the principle of voice spreading in the indoor.(2)The system of delaying wave filtering is built by the simulation. And also, the bullet data will be gathered by the uniform signal which is triggered by triggered network.(3)The remote spying system is designed to complement temperate scene control and the trigger situation or delay time control.According to a large amount of experimental results and statistics, the method mentioned in the research is proved to precisely capture the gunpoint information and observe the trigger status and environment temperate by remote real-time supervision. Meanwhile, it also illustrates the validity and feasibility of the method.
