Control device for hail impact test and operation method thereof

Abstract

The invention discloses a control device for hail impact test and an operation method thereof. The control device comprises an upper computer and a lower computer; wherein the upper computer comprises an LED velocity indicator, a first microprocessor, a first controller, an optoelectronic isolator, a first communication module, a control valve, a switch and a boost controller; the lower computer comprises a first photoelectric sensor, a second photoelectric sensor, a second microprocessor, a second controller and a second communication module; the operation method comprises the following steps: by utilizing the boost signal and the sending signal of the first controller, respectively starting an air booster pump and sending hail balls through the first microprocessor and the optoelectronic isolator, the hail balls respectively passing through the first photoelectric sensor and the second photoelectric sensor to obtaining an interrupt signal, calculating the hail ball velocity signal through the second microprocessor, and sending the hail ball velocity signal to the LED velocity indicator via the communication module and the first microprocessor. The invention realizes the requirement on multiple sending in hail tests in a short period of time, and ensures the sending conformity and data accuracy.

Description

technical field [0001] The invention relates to a hail emission control device and a working method for the hail impact reliability test, and is also suitable for other small particle impact tests. Background technique [0002] At present, there are no relevant reports on the hail impact test in China. There are relevant test standards in the United States abroad, but there are no detailed elaborations and requirements for the launch process and launch system of hail. For the domestic bird strike test carried out on the same principle as the hail impact test, the test process and control are all manually controlled, and the membrane-rupturing method is generally used. The disadvantage of the membrane-breaking manual launch control is that the launch time cannot be accurately controlled, and each launch time has a large change. At the same time, the launch time cannot reach the microsecond level standard, and the preparation time for a single launch is long. (1 minute) Conti...
