Embodiment Construction

[0035] A verification system for the data transmission bus of the payload subsystem, consisting of a bus test computer (001), a bus terminal equivalent (002), a bus monitor (003), a bus controller (004), and 2 payloads Composed of transmission bus (master / standby) and 1 CAN bus.

[0036] The bus terminal equivalent (002) receives the command from the bus controller (004), simulates the behavior of the payload equipment on the star, and receives the data of the CAN bus, and changes the terminal equivalent according to the command of the bus test computer (001). telemetry value. The number of bus terminators (002) can be extended to 31.

[0037] The bus monitor (003) is used to monitor the data on the payload transmission bus, and transmit the data back to the bus test computer (001) through the CAN bus.

[0038] The bus controller (004) completes the simulation of the behavior of the master control end of the payload transmission bus, sends instructions to the payload device ...

Abstract

A verification method for the data transmission bus of the payload subsystem. First, the payload device on the star and the bus master are simulated, and the payload control command is generated and sent to the corresponding payload device on the star. When receiving the payload control command, and then generate telemetry data and send it to the bus test computer, then monitor the data on the payload transmission bus, and return the monitored data to the bus test computer in real time, and finally control the bus test computer according to the real-time monitoring data and received The telemetry data is used to complete the correctness analysis of the payload transmission bus data transmission. The test content of the present invention is comprehensive and effective, and the software and hardware interfaces are exactly the same as those on the star. It can represent the payload of the real star and its main control terminal to conduct a full-coverage test on the function and performance of the data transmission bus, and has good use value.

Description

technical field [0001] The invention relates to the technical field of satellite bus systems, in particular to a verification system and method for a payload subsystem data transmission bus. Background technique [0002] Communication satellite payload system equipment mainly includes traveling wave tube amplifier (TWTA) multi-functional components, frequency converters, receivers, etc. The demand for telemetry and remote control of these load demand is also increasing. The foreign advanced large-capacity communication satellite platform SB4000 and E3000 platform both use the form of the bus to realize the remote control and telemetry of the load equipment. Domestic communication satellites have also begun to use the bus form to meet the telemetry and remote control requirements of the load compartment equipment. In the utility model patent "A Bus for Data Transmission of Payload Subsystems" (CN201120326416), a bus for payload distribution is disclosed. The bus for system ...
