Configurable Remote Control Telemetry Simulator with Monitoring Function and Control Test Method

Abstract

The invention discloses a configurable remote control telemetry simulator with a monitoring function, which includes a remote command control module, a telemetry acquisition module and a 1553B control module. The remote command control module includes a remote control communication module, a command sending module, a command monitoring module and a command switching module ;The host controller transmits the instruction information to the remote communication module, and the remote communication module analyzes the instruction information and outputs the instruction signal to the star through the instruction sending module; the instruction monitoring module collects the instruction signal and compares it with the instruction information, if the instruction If the signal does not match the command information, the command signal output is cut off; if the command signal is consistent with the command information, the command signal is normally output to the star; the command switching module realizes the match between the configurable interface circuit of the command sending module and the interface on the star. Each functional module of the invention is independent, easy to transplant, high in maintainability, and can meet the processing requirements of remote control and telemetry input and output signals.

Description

technical field [0001] The invention relates to a configurable remote control telemetering simulator with a monitoring function and a control test method, which are suitable for ground test verification of a spacecraft control system. Background technique [0002] The remote control telemetry simulator is a necessary equipment before the test of the aerospace control subsystem. The reliability of the remote control telemetry simulator is very important for the test of the control subsystem. [0003] The current remote control telemetry simulator adopts the CPCI architecture, and uses boards such as IO, A / D, and D / A based on the CPCI bus. The remote control telemetry simulator needs to be equipped with special IO boards, A / D, D / A, serial boards, etc. There are many types of boards, difficult to maintain, and inconvenient to use. [0004] When there are functional requirements such as I / O and A / D at the same time, the system must be configured with different types of boards t...

AI Technical Summary

Problems solved by technology

When the logical timing between the IO board and the A / D board is related, it can only be processed by the software of the host computer, but cannot be completed at the hardware level of the control board, which increases the complexity of software implementation

[0005] At the same time, the logic addresses of the upper computer and the bottom board of the existing remote control telemetry simulator are fixed and cannot be changed. The hardware system registers and variables cannot be changed through the upper computer. They are only suitable for specific functional requirements and are not easy to transplant

[0006] The existing remote control telemetry simulator does not monitor the commands sent out, whether the command timing is correct, whether the pulse width length is correct, and the execution status cannot be judged

It is also impossible to compare and verify the instructions and program block data sent by the 1553B bus

[0007] Due to the specialization of equipment, there are some restrictions on portability, and the lack of monitoring and configurability capabilities, there are deficiencies in the application of other aerospace models
