Embodiment 1

[0025] Such as figure 1 As shown, a configuration method based on the satellite-borne equipment communication protocol provided by the present invention includes specific steps as follows:

[0026] Step a: select the on-board device simulator, and configure the general parameters of its corresponding communication protocol;

[0027] Wherein, the general parameters are different according to different communication protocols; the general parameters include channel number, baud rate, node number, parity bit, stop bit, response delay, frame interval delay and byte interval delay Any one or more of these times.

[0028] Step b: According to the data agreement between the on-board device simulator and other on-board devices, configure the sequence parameters of their corresponding communication protocols;

[0029] Wherein, the data agreement includes data format and data interaction mode, the data format is any one or more of the corresponding information represented by data leng...

Embodiment 2

[0034] Such as figure 2 As shown, a configuration method based on the satellite-borne equipment communication protocol provided by the present invention is roughly the same as Embodiment 1, and the main difference is that Embodiment 2 also includes the following steps:

[0035] Step d: Monitor the operation status of the corresponding data interaction between the on-board device simulator and other on-board devices, and save the data received and sent according to the corresponding communication protocol for query and analysis.

Embodiment 3

[0037] Embodiment 3 of the present invention provides a configuration method based on an on-board device communication protocol, which uses the serial port communication protocol as a specific embodiment to describe the technology in detail. According to the data interaction mode, the serial port communication protocol can be divided into two types: selection and response.

[0038] The data interaction method described above is that when selected, the onboard equipment simulator only sends data, and in a certain set period, according to the general parameters and sequence parameters, the data is sent through the communication interface according to the set timing.

[0039] The data interaction method is that when responding, the on-board device simulator receives the data and responds to the received correct data according to the communication protocol. The response data is included in the general parameters and sequence parameters. If wrong data is received, no response will...

Abstract

The invention relates to a configuration method based on a satellite-borne equipment communication protocol. The configuration method comprises the following steps of selecting a satellite-borne equipment simulator, configuring general parameters of a communication protocol corresponding to the satellite-borne equipment simulator, configuring sequential parameters of the communication protocol corresponding to the satellite-borne equipment simulator according to a data convention between the satellite-borne equipment simulator and other satellite-borne equipment, and allowing the satellite-borne equipment simulator to conduct corresponding data interaction with the other satellite-borne equipment according to the configured general parameters and the sequential parameters. The method has the advantages of good generality, low cost, convenience in realization and maintenance, and the like.

Description

technical field [0001] The invention relates to a configuration method of a communication protocol, in particular to a configuration method based on a satellite-borne device communication protocol. Background technique [0002] Information is transmitted between various spaceborne devices of the satellite through a set communication protocol, so multiple communication protocols may exist on the same satellite at the same time. Two or more spaceborne devices can choose different communication protocols according to the requirements of data interaction, and exchange information through the data agreement of the communication protocol between spaceborne devices on the basis of mature communication hardware interfaces. [0003] The communication protocols and data agreements adopted between different satellites or different spaceborne devices of the same satellite have their own characteristics, especially the format of the protocol is set according to their own needs. Due to t...
