Reinforced type data acquisition system

Abstract

The invention provides a reinforced type data acquisition system which comprises a portable data acquisition system body and a handheld data acquisition system body. A case which is formed through integrated forging and pressing of aluminum alloy is sealed by aluminum alloy panels. Reinforcing ribs are arranged on the inner wall of the case, and heat radiating grooves are formed in the outer wall of the case. A circuit module in the portable data acquisition system body is fixedly connected with the case in an inserting-connection mode and fastened through locking bars. Circuit modules in the handheld data acquisition system body are stacked in the case, and a power source module supplies power to the circuit modules. The reinforced type data acquisition system is suitable for acquisition of testing data of a large-equivalent-weight static explosion test, and the reinforced and miniaturized design is adopted, so that the requirements for dust prevention, vibration prevention, strong electromagnetic interference resistance and portability are met.

Description

technical field [0001] The invention belongs to the technical field of shooting range test and test, and relates to a test system for collecting and recording electrical signals such as shock waves and fragment velocities. Background technique [0002] The static explosion test power parameter test is a very important link in the ammunition development process. Through the static explosion test power parameter test, the explosive power of the ammunition can be assessed, and the necessary test data can be obtained to provide test data support for the design improvement and effectiveness evaluation of the ammunition. With the development of the large-equivalent warhead power test, compared with the ordinary warhead static explosion test, the shock vibration generated by the warhead explosion is greater, and the destructive effect is much greater than that of ordinary explosives. It is necessary to reliably collect shock waves, For data such as fragments, it is required that th...

Problems solved by technology

In the process of using and transporting this kind of structure, the board card is very easy to loosen and oxidize, so that the board card cannot be detected after starting up, which affects the collection of test data, and because there are a large number of cooling holes on the chassis, the dustproof effect is poor. During the field test, dust and sand can easily enter the chassis and affect the performance of the equipment. In ordinary small equivalent static explosion tests, sponges are generally used to wrap the chassis around for vibration reduction and dust prevention. In large equivalent static explosion tests, Due to the strong vibration and shock generated when the warhead explodes, the case shell of the data acquisition equipment may be cracked, causing the board slot to become loose, and data such as shock waves and fragments cannot be collected, which will affect the evaluation of the test results. Therefore, it is urgently needed Develop a new data acquisition system with ruggedized and dust-proof functions to meet the test requirements of large-equivalent static explosion tests for new ammunition weapon systems
