Ship target damage effect evaluation test device

Abstract

The invention discloses a ship target damage effect evaluation test device, which combines a wireless data transmission technology with a black box test technology to construct an upper and lower computer wireless communication network. The upper computer carries out data acquisition, storage and transmission through wirelessly and remotely controlling the lower computer, and collects data of thelower computer test black box and damage effect evaluation software to carry out seamless interface; the lower computer test black box can wirelessly transmit test data to the upper computer within alimited time from the end of an explosion test to the front of ship sinking, and can salvage and recover the black box through the recovery positioning device after the ship body sinks, and then perform secondary data read-back. According to the device, a wireless transmission and secondary storage dual-data backup scheme is adopted, so that a function of immediately displaying data after a test can be realized, and reliable acquisition of the data in an extreme environment can also be ensured; the device and the related technology are particularly suitable for dynamic and transient test of weapon systems in sea, lake and conventional severe environments.

Description

technical field [0001] The invention belongs to the technical field of dynamic / transient shooting range testing, and in particular relates to a damage effect evaluation testing device of a ship target. Background technique [0002] The damage effect test of ship target has increasingly become a hot spot in the current maritime weapon performance evaluation research. By testing the structural dynamics and transient acceleration, strain, shock wave overpressure, temperature and other response signals of the ship target under the environment of explosive explosion impact and high-speed collision impact, the measured parameters are provided to the damage effect evaluation system of the ship target, and the damage effect It is of great significance to verify and improve the evaluation model to provide data support and improve the accuracy of weapon battlefield performance evaluation. [0003] At present, there are two main methods of sea state test for ships: [0004] The first...

Problems solved by technology

[0004] The first type: arrange various types of sensors in various parts of the ship, and lead their signals from the test part to the ground measurement and control room several kilometers away or the centralized test system on the remote command ship for data collection, storage, analysis and processing through long-term transmission. This technology test is relatively intuitive, and the test data can be displayed synchronously during the test, but it also has certain defects: due to the long distance between the test sensor and the test system, the anti-interference ability of the test signal is poor, and the signal inevitably has long-term attenuation problems. At the same time, the test wiring of multi-channel signals is difficult, and the test cables require waterproof and bundled treatment, etc., resulting in low test work efficiency

But there are also some defects: the bus-type test system is bulky and the design of the protective structure is difficult; in addition, the acquisition of different types of signals generally corresponds to different test systems, resulting in a wide variety of test systems used in the test, various formats of test data, and multiple sets. The acquisition and synchronization of the test system are relatively difficult, and the bus-type test instruments are expensive, and once they are damaged during the test, the loss will be large

Considering that the damage effect test of the ship target is carried out in a specific environment at sea, there are certain risks in the test, mainly because the test personnel cannot operate the test system on the ship at close range and in real time for testing in the environment of the first explosion impact, and there is a risk of personnel safety. risk; after the second explosion test, the ship target may sink in seawater, resulting in damage to the test device, and the test data cannot be obtained reliably; third, in the case of an abnormally large number of measurement points, the sensor signal is transmitted on the ship through long-term transmission It is quite difficult to implement the technical solution of transmitting to the measurement and control room several kilometers away for wired testing
