Design on Device for Remote Realtime Monitoring Measuring the Burst Point Time
Aiming at the existent burst point time measurement device was unable to show the burst point time measurement situation and had a big measurement error, avalanche photodiodes (APD) were used as photoelectric detectors, wireless data transmission modules were applied to transmit burst signal timely and directly timed by PC instead of traditional timing circuits to improve timing accuracy. The amplifying circuit based on APD was designed, photoelectric receiver module was built, and the falling edge width of the output pulse signal was less than 25 ns. Of the wireless data transmission module, the transmitter was contacted to photoelectric receiver module, and the receiver connected with PC. Through the wireless communication between the transmitter and the receiver, the pulse signal when the ammo was outing of the muzzle and exploding was passed on to the PC that was 1~3 km away. The measurement situation was monitored realtimely, the burst point time was read intuitively, and interference signals could be artificially filtered. Measuring the burst point time of a test bomb, which was 124.056 ms, the results of the test experiment shows that the device is able to effectively realize remote realtime monitor the burst point time with high measuring accuracy. This design can provide a reference for the optimization and improvement of the burst point time measuring device.
