Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0016] The term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "inner", "lower", etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may include one or more of the features explicitly or implicitly.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0017] In order to solve the problems existing in the prior art, an automatic test system for a fuze firing control component is disclosed. The system comprises a computer master control module, a test module, a component assembly module to be tested and a voltage-stabilized power supply. The computer master control module comprises a multi-function card, and the multi-function card comprises a plurality of signal acquisition units, and the plurality of signal acquisition units are at least used to collect current signals, voltage signals and explosion height information of the component to be tested; the test module is electrically connected to the component assembly module to achieve performance testing of the component to be tested under test conditions, and the test module comprises a relay board, a cable terminal and a terminal board. One end of the relay board is controlled by the computer master control module to switch a test circuit to meet corresponding test conditions, and the other end of the relay board is electrically connected to the cable terminal and the terminal board respectively, and the other end of the cable terminal is electrically connected to the component to be tested or communicates with the component to be tested through an input antenna, and the other end of the terminal board is electrically connected to the multi-function card; the component to be tested is a fuze firing control component under a target application environment, and the voltage-stabilized power supply is used to provide a test voltage for the test system.

[0018] Among them, when the test module needs to test the current signal and voltage signal of the component to be tested, it is electrically connected to the component to be tested through the cable terminal to collect the current and voltage signals of the component to be tested and transmit them back to the multi-function card. Further, when the test module needs to test the explosion height information of the component to be tested, the multi-function card outputs a simulation signal, which can be a simulated height signal or an environmental signal. For example, it can be a numerical value representing a specific height or atmospheric pressure, or a signal simulating environmental conditions at a specific height. On the ground, the atmospheric pressure is high, and as the height increases, the atmospheric pressure will gradually decrease. Therefore, this simulation signal may simulate the change of this atmospheric pressure to simulate different height conditions. During the test, the multi-function card will send this simulation signal to the component to be tested through the antenna. The component to be tested will adjust its state according to this signal, thereby simulating the working state at different heights. Then, the multi-function card will collect the current signal, voltage signal, etc. of the component to be tested in this state to evaluate the performance of the component to be tested at different heights. Finally, the test performance that meets the target performance requirements is selected, and the height corresponding to the test performance that meets the target performance requirements is used as the explosion height of the component to be tested (fuze ignition control component), so that at this height, other influencing data that can achieve the explosion height, such as current, resistance, etc., can be adjusted.

[0019] It can be understood that the functional card of this scheme integrates multiple signal acquisition units, which can realize the acquisition and testing of various information such as current signal, voltage signal and explosion height information of the component to be tested, and meet the complex testing requirements of the fuse ignition control component; further, through the coordinated work of the computer master control module and the test module, the system can automatically complete the performance test of the component to be tested (fuze ignition control component), improve the test efficiency, and reduce the time and labor cost required for manual testing; further, through the design of the relay board, the test circuit can be flexibly switched to meet different test conditions. Through the control of the computer master control module, the test parameters and test process can be easily adjusted, which enhances the flexibility and controllability of the test; further, the electrical connection or communication with the component to be tested is realized through the cable terminal and the terminal board, ensuring the accurate transmission and reception of the test signal. At the same time, the stabilized power supply provides a stable test voltage for the test system, further ensuring the accuracy and reliability of the test results; further, by integrating the computer master control module, the test module, the component assembly module to be tested and the stabilized power supply and other components into a system, a compact and efficient test system is formed. This highly integrated design makes the system easier to deploy, maintain and use.

By controlling and adjusting the position and state of the input antenna, the antenna driving board can ensure the stable transmission of wireless communication signals, improve the flexibility and accuracy of communication, and thus improve the accuracy and reliability of the test results.

The power terminal is used as a key component to connect the relay board and the voltage-stabilized power supply, thereby ensuring that the fuse firing control component can obtain a stable and reliable power supply during the test process.

[0024] In some embodiments, the regulated power supply is connected to the computer master control module via a serial interface.

[0025] In some embodiments, the test module further includes a resistance box, one end of which is electrically connected to the cable terminal, and the other end of which is electrically connected to the relay board, and the resistance box is used to adjust the resistance of the test circuit.
