Embodiment 1

[0030] Such as figure 1 As shown, the data encoding transmission method based on Beidou communication according to the embodiment of the present invention includes the following steps:

[0031] A10: Encapsulate the data to be transmitted into a frame, the data to be transmitted includes power data and / or upgrade data, where each frame of data includes a frame information area and a data area, and the information capacity of each frame of data is the same as the frame required by the Beidou RDSS IC card The data length is consistent; the data area records the data to be transmitted; the frame information area includes the first information area and the second information area, and the first information area records the frame type information of the current frame;

[0032] A20: According to different frame types, the second information area records different information;

[0033] A30: Send the frame data to the Beidou satellite.

[0034] It should be noted that the Beidou commun...

Embodiment 2

[0053] Such as Figure 5 As shown, the Beidou communication device for power metering according to another embodiment of the present invention includes: a data processing module and an RDSS communication module. The data processing module is used to encapsulate the data to be transmitted into a frame, the data to be transmitted includes power data and / or upgrade data, wherein each frame of data includes a frame information area and a data area, and the information capacity of each frame of data is the same as that of the Beidou RDSS IC card The required frame data length is consistent; the data area records the data to be transmitted; the frame information area includes the first information area and the second information area, the first information area records the frame type information of the current frame; according to different frame types, the second information area Record different information. The RDSS communication module obtains the frame data of the data processi...

Embodiment 3

[0062] Such as Figure 6 As shown, the power metering terminal according to another embodiment of the present invention includes: a Beidou communication device and a power metering terminal body, and the Beidou communication device is the Beidou communication device for power metering described in the above embodiments. The power metering terminal body establishes a signal connection with the Beidou communication device, and the power metering terminal body transmits the data to be transmitted to the Beidou communication device.

Abstract

The invention discloses a data encoding transmission method, terminal and system based on Beidou communication. The method includes the following steps, each of which is in no particular order: S10: Encapsulate the data to be transmitted into a frame, and the data to be transmitted includes power data and / or upgrade data, wherein each frame of data includes a frame information area and a data area, and the information capacity of each frame of data is consistent with the frame data length required by the Beidou RDSS IC card; the data area records the data to be transmitted; the The frame information area includes a first information area and a second information area, the first information area records the frame type information of the current frame; S20: according to different frame types, the second information area records different information; S30: the The frame data is sent to the Beidou satellite. It is used to solve the long-standing problem of low transmission space utilization in the Beidou communication data transmission process in the prior art.

Description

technical field [0001] The present invention relates to the field of Beidou data transmission, in particular to a data coding transmission method, terminal and system based on Beidou communication. Background technique [0002] The Beidou satellite navigation system is a global satellite navigation system independently developed by China. It consists of three parts: the space segment, the ground segment and the user segment. , timing service, and short-message communication capability. It has preliminary regional navigation, positioning and timing capabilities, with a positioning accuracy of 10 meters, a velocity measurement accuracy of 0.2 m / s, and a timing accuracy of 10 nanoseconds. [0003] The Beidou short message function can be regarded as the "short message" that people usually use. The two-way briefing digital communication between users can be realized through the two-way communication function of Beidou. At present, the message communication that Beidou card can s...
