Problems solved by technology

[0004] However, this kind of box bomb simulator can only simulate the completely correct electrical properties of the box bomb, and does not simulate some errors that may occur in actual operation. Although this can test the normal process of software and hardware in the launch control system, it cannot Verify the launch control system's process handling in the event of an error
If some errors occur during the actual launch, and there is a problem with the launch control system's handling of the error process, the consequences cannot be estimated

Abstract

The invention provides a communication fault simulating device and method of a box simulator, relates to the field of communication, and satisfies requirements of simulating normal work state and fault state simultaneously. An RS422 communication circuit receives control / test command, satisfying the RS422 level standard, of an emission control system, and sends the satisfied control / test command to a protocol processing circuit; a fault code monitoring circuit monitors a fault code level signal generated by a dial switch via a toggle switch in a cyclic manner, converts the fault code level signal into an extra protocol conversion reference, and transmits the reference to a protocol conversion circuit; the protocol processing circuit searches for a stipulated command answer sheet according to the received fault monitoring code which is monitored by the fault code monitoring circuit, and outputs a corresponding command answer code of the fault monitoring code to the RS422 communication circuit via the command answer sheet, and the RS422 communication circuit outputs the corresponding command answer code to the emission control system. The device and method are suitable for communication simulation.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a fault simulation device and method for digital communication. Background technique [0002] The box bomb simulator is a supporting equipment in the box bomb launch control system. In order to ensure that all the software and hardware of the box bomb launch control system can work normally and stably before launching, the box bomb simulator needs to be tested and controlled in advance. To verify the functional correctness of the box bomb launch control system, to ensure that the launch task can be successfully completed. Because the box bomb simulator has the ability to fully simulate the electrical properties of the box bomb, it is also used as a tool for the early debugging of the launch control system. The launch control system can be docked with the box bomb simulator to verify its soft, The functional correctness of the hardware. [0003] Existing box bomb simulators are usu...
