[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and should not be construed as limiting the scope of this invention.
[0029] It should be noted that although functional modules are divided in the diagram, in some cases, the modules can be divided differently from those in the system.
[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution. If terms such as "first" or "second" are used in the description, they are only for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.
[0031] Reference Figure 2 , Figure 3 , Figure 4 In some embodiments of this utility model, a training device for simulating aviation CVR system malfunctions includes:
[0032] Main control module and fault simulation circuit module; The main control module is connected to the fault simulation circuit module and is used to send signals to the fault simulation circuit module and control the fault simulation of the fault simulation circuit module.
[0033] The fault simulation circuit module includes a basic simulation circuit and a relay KAn;
[0034] A basic analog circuit, connected to relay KAn, used to simulate an aviation CVR system.
[0035] The relay KaN has its normally closed terminal connected to the simulated fault point in the basic analog circuit, its normally open terminal open, and its coil terminal connected to the main control module. It is used to receive signals sent by the main control module and control the closing of the circuit accordingly.
[0036] Users issue simulated fault commands through the main control module. The main control module, based on these commands, short-circuit or open-circuit the basic simulation circuit via relay KAn, thereby controlling the fault simulation circuit module to simulate the fault. Specifically, when simulating maintenance or requiring normal operation of the CVR system circuit, the main control module does not send a signal to relay KAn, which remains normally closed, and the basic simulation circuit operates normally. When simulating a fault, the main control module sends a signal to relay KAn, which becomes normally open. A short circuit or open circuit in the basic simulation circuit is then considered a fault at that point, thus simulating a specific fault point in the CVR system circuit and helping users enhance their training on aviation CVR system faults. This invention dynamically simulates aviation CVR system faults through the dynamic control of relay KAn by the main control module, dynamically switching fault points in real time to enhance training effectiveness.

One end of the broken circuit is connected to one end of the normally closed terminal of relay KAn, and the other end of the broken circuit is connected to the other end of the normally closed terminal of relay KAn. When relay KAn is normally closed, the basic analog circuit can operate normally at the simulated fault point through relay KAn. When relay KAn is normally open, the basic analog circuit breaks the circuit at the simulated fault point through relay KAn.
[0040] Reference Figure 2 In some embodiments of this invention, the relay KAn is a six-pin relay. One normally closed terminal is connected to one end of the simulated fault point in the basic analog circuit, and the other normally closed terminal is connected to the other end of the simulated fault point in the basic analog circuit. One end of the coil is connected to the main control module, and the other end of the coil is grounded. Both ends of the normally open terminal are open-circuited. When the main control module sends a high-level signal, the coil of the relay KAn generates current, the normally closed terminal of the relay KAn opens, and the simulated fault point in the basic analog circuit is disconnected.

That is, the normally closed terminal of relay KA1 (number 1) is C1 at one end and NC1 at the other; the normally closed terminal of relay KA2 (number 2) is C2 at one end and NC2 at the other… and the normally closed terminal of relay KA28 (number 28) is C28 at one end and NC28 at the other.
