Full-electronic fuze tester with double redundant designs and testing method using the same

Abstract

The invention provides a full-electronic fuze tester with double redundant designs and a testing method using the same. The full-electronic fuze tester comprises an AC-DC power supply, a voltage converter, a single chip microcomputer, an indicator lamp, a first CPLD, a second CPLD, a driving circuit, a connector and a relay. The single chip microcomputer is electrically connected to the first CPLD, the second CPLD, the voltage converter, the connector, the relay and the indicator lamp. The AC-DC power supply is electrically connected to the voltage converter and the relay. The voltage converter is electrically connected to the first CPLD, the second CPLD and the single chip microcomputer. The driving circuit is electrically connected to the first CPLD, the second CPLD and the connector. The tester can respectively detect double function modules in a fuze, also can simultaneously detect the double function modules and can guarantee the completeness of the full electronic fuze testing with double redundant designs. According to the detection result, the initial fault location of the faulty fuse in the inner functional module is convenient.

Description

technical field [0001] The invention relates to the field of fuze detection, in particular to a double-set redundant design fully electronic fuze tester and a test method thereof. Background technique [0002] The fuze is the detonating device on the missile weapon system and is an important part of the entire weapon system. With the development of targets, warheads, combat methods and science and technology, the functions of the fuze are also constantly improving. In order to ensure the safety and reliability of the fuze, the functional modules inside the fuze can adopt a redundant design of double backup, which can ensure that when one of the functional modules of the fuze fails, the fuze can still work normally Work. The fuze test device is an important tool to evaluate the performance of the fuze, and its test results can directly reflect the quality of the fuze. For the fully electronic fuze with dual backup redundant design, it is extremely important to be able to f...

Problems solved by technology

[0005] If the all-electronic fuze tester can only provide one set of release and reset signals, then for the full-electronic fuze with dual redundant design, when sending the release signal and reset signal, the dual sets of functional modules inside the fuze receive the signal at the same time , Return the feedback signal, if the internal functional module is faulty, the fuze detection result provided by the full electronic fuze tester can only show that the tested fuze is abnormal, and cannot perform preliminary positioning on the faulty functional module of the fuze
