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

The invention relates to a verification method for a payload subsystem data transmission bus. The method comprises the following steps: first simulating the on-board payload device and the bus master,generate a payload control command and send it to the corresponding on-board payload device. When the payload control command is received, the telemetry data is generated and sent to the bus test computer, and then the data on the payload transfer bus is monitored. The monitored data will be transmitted back to the bus test computer in real time, and finally the control bus test computer will monitor the data and the received telemetry data according to the real time. The analysis of the correctness of the payload transmission bus data transmission can be completed. The test content is comprehensive and effective, and the software and hardware interfaces are exactly the same as those on the star. The method can represent the true star payload and its main control terminal for full coverage test of the function and performance of the data transmission bus with 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 ...
