Abstract

The invention discloses a Beidou data transmission method based on confirmation mode, wherein a special data encoding method and communication sequential control are adopted, an announcement call function included by a Beidou command terminal is combined, and confirmation for the self-reported data of all telemetering stations in a system is realized in a Beidou data message, so as to avoid the problem of increase for the power consumption of the telemetering stations due to too large time delay caused by a point-to-point confirmation mode; and moreover, communication expense can be greatly saved.

Description

technical field

[0001] The invention relates to a Beidou data transmission method, which belongs to the technical field of Beidou communication. Background technique

[0002] The Beidou satellite system was originally designed for navigation and positioning services, but the system also includes certain data communication functions. Due to the small transmission delay and lower communication costs than other satellite systems, Beidou satellites have been widely used in mountain torrent disaster monitoring and early warning, In real-time information telemetry systems such as automatic water regime forecasting, automatic weather monitoring, and ocean monitoring and early warning. These telemetry systems are generally composed of multiple telemetry stations responsible for information collection and a data receiving central station. The data collection terminal included in the telemetry station collects information regularly, and sends information to the central station through...

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] The present invention adopts a special data encoding method and communication timing control, combined with the broadcast function contained in the Beidou command terminal, realizes the confirmation of the self-reported data of all telemetry stations in the system in a Beidou data message, so as to avoid point-to-point The excessive delay caused by the confirmation method leads to the problem of increasing the power consumption of the telemetry station, and can greatly save communication costs.

[0029] A Beidou data transmission method based on confirmation mode, comprising the following steps:

[0030] 1) In an information collection system consisting of several telemetering stations responsible for data collection and a data receiving central station, the telemetry station and the data receiving center transmit data through the Beidou satellite ( figure 1 sh...
