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

A communication fault simulation device and method for a box bomb simulator, relating to the communication field. It satisfies the requirement of simulating normal working state and fault state at the same time. The RS422 communication circuit receives the control / test command conforming to the RS422 level standard of the emission control system, and sends the control / test command conforming to the RS422 level standard to the protocol processing circuit; The generated fault code level signal is converted into an additional protocol conversion reference according to the generated fault code level signal, and sent to the protocol conversion circuit; the protocol processing circuit searches for the agreed command based on the fault monitoring code monitored by the received fault code monitoring circuit Response table, and output the command response code corresponding to the fault monitoring code to the RS422 communication circuit according to the command response table, and then output to the launch control system after passing through the RS422 communication circuit. The invention is suitable for communication simulation.

Description

technical field [0001] The invention relates to the communication field, in particular to a fault simulation device and method for digital communication. Background technique [0002] The box bomb simulator is the 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, it is necessary to test and control the box bomb simulator in advance. To verify the functional correctness of the box bomb launch control system and ensure the successful completion of the launch mission. Since the box bomb simulator has the ability to completely simulate the various electrical properties of the box bomb, it is also used as a tool for early debugging of the launch control system. The launch control system can verify its softness, Functional correctness of the hardware. [0003] Existing box bomb simulators are usually designed to be completely consis...
