Contact fuse with redundant design of sensor

Abstract

The invention provides a contact fuse with a redundant design of a sensor. The contact fuse comprises a safety control assembly, a commutation triggering assembly, a detonation assembly, a sensor and signal processing assembly, an input/output port and a power assembly, wherein the safety control assembly is electrically connected with the input/output port, the sensor and signal processing assembly and the commutation triggering assembly; the sensor and signal processing assembly is electrically connected with the commutation triggering assembly; the commutation triggering assembly is further electrically connected with the detonation assembly; and the power assembly is connected with all the assemblies. According to the contact fuse, a contact switch and a piezoelectric sensor are comprehensively applied to generating a fuse detonation signal which is transmitted to the commutation triggering assembly in the fuse, and an energy storage capacitor in the control assembly outputs energy to an electric detonator in the detonation assembly, so that detonation operation is realized, and detonation energy can be output to the outside.

Description

technical field [0001] The invention relates to a detonation fuze for a blasting device, in particular to a trigger fuze with redundant sensor design. Background technique [0002] The fuze is an important part of the weapon system. It uses target and environmental information to detonate or ignite the charge of the warhead of the ammunition under predetermined conditions. It is usually installed on ammunition such as rockets, missiles, and torpedoes. The trigger fuze (impact fuze) is a fuze that uses the information of hitting the target to ignite. Specifically divided into prompt fuze and inertial trigger fuze. The prompt trigger fuze is a fuze that uses the reaction force of the target to ignite, and the inertial trigger fuze is a fuze that uses the forward momentum generated by the deceleration of the projectile when it hits the target. [0003] The explosion switch The explosion switch is composed of a shell, an explosion lever, an explosion safety spring, an insulati...

Problems solved by technology

Li Haojie and others from Nanjing University of Science and Technology published a paper on the application of piezoelectric ceramics in fuze surface differential pressure sensors, discussing the use of piezoelectric sensors for the identification of fuze flight environments, but did not discuss the use of piezoelectric sensors in fuzes. A detonation signal is generated in the trigger fuze

Huo Mingzhou and others from the 705th Research Institute published a paper on the torpedo piezoelectric inertial fuze, discussing the design idea of ​​using a single piezoelectric sensor to generate a detonation signal in the trigger fuze, but did not consider using a bump switch to make up for the deficiency of the piezoelectric sensor

At present, there is no public report on the comprehensive application of the detonation switch and the piezoelectric sensor to generate the detonation signal of the fuze
