A telemetry and remote control data transmission device between 1553b bus and intra-satellite equipment bus

Abstract

A device for transmitting telemetric and telecontrolled data between a 1553B bus and a satellite interior equipment bus comprises a 1553B bus module, a singlechip module and a satellite equipment bus management module. The satellite interior equipment bus management module is not used in the traditional design method, and telemetric and telecontrolled management of satellite interior equipment is realized by using a singlechip only; along with increasing of the number of satellite-borne equipment, the complexity of control logic of the singlechip is increased, and the reliability of a system is affected; and moreover, because the singlechip works in a serial mode, the singlechip only can acquire and process one telemetric parameter every time, the updating period of the telemetric parameters of the whole satellite is longer and longer, and detection and isolation of faults are affected. The device can overcome the shortcomings; the design of a singlechip system is simplified by the satellite interior equipment bus management module, and the control and management capability of the system on telemetry and telecontrol to the satellite equipment is improved.

Description

technical field [0001] The invention relates to a telemetry and remote control data transmission device between different satellite-borne equipment buses, in particular to the data transmission between the 1553B bus and the intra-satellite equipment bus. Background technique [0002] The 1553B bus is the first-level bus of the satellite system, which is responsible for the transmission of the remote control and telemetry data of the whole satellite. The intra-satellite equipment bus is the second-level bus of the satellite system, responsible for the transmission of remote control and telemetry data of specific equipment. [0003] The management of data such as telemetry and remote control in the star is realized through the network of the 1553B bus and the device bus in the star. In the traditional design, the data conversion between the 1553B bus and the intra-satellite device bus is realized by the single-chip microcomputer module. With the increase of on-board equipmen...

AI Technical Summary

Problems solved by technology

With the increase of space-borne equipment, the control logic surrounding the single-chip microcomputer becomes more and more complex, and the reliability of the equipment is also affected

Due to the serial working mode of the single-chip microcomputer, only one telemetry parameter can be collected and processed at a time, and the update cycle of the telemetry parameters of the whole star is long, which is not conducive to the fault detection and isolation of the system
