BeiDou terminal control system for reliable transmission of BeiDou short message

Abstract

The invention discloses a BeiDou terminal control system for reliable transmission of a BeiDou short message. The BeiDou terminal control system comprises a main chip processing module, a BeiDou positioning module, a BeiDou short message module and a Bluetooth module, wherein the main chip processing module is used for processing working information of each functional modules; the BeiDou positioning module is connected to the main chip processing module and is used for communicating with a BeiDou satellite; the BeiDou short message module is connected to the main chip processing module and isused for being connected to a BeiDou RD control center as a transfer forwarding station when the BeiDou short message is transmitted, carrying out logic judgment and secondary processing on short message data through the BeiDou RD control center, carrying out short message transmission, and sending the short message data to other receiving terminals through the BeiDou satellite; and the Bluetoothmodule is connected to the main chip processing module and is used for communicating with intelligent equipment and controlling the main chip processing module after receiving an instruction. According to the BeiDou terminal control system, the effectiveness, the reliability and the stability of BeiDou short message transmission are improved, operation is carried out through the intelligent equipment, and the functions of positioning and navigation and the like can be realized.

Description

technical field [0001] The invention belongs to the technical field of Beidou navigation equipment control, and in particular relates to a Beidou terminal control system for reliable transmission of Beidou short messages. Background technique [0002] China's BeiDou Navigation Satellite System (BDS) is a global satellite navigation system developed by China itself. It can provide all kinds of users with high-precision, high-reliability positioning, navigation, and timing services around the clock and around the world, and has short message communication capabilities. The Beidou terminal refers to the use of the Beidou satellite navigation system for positioning and navigation. Terminal Equipment.

Problems solved by technology

With the country's strong support for the Beidou system's military-to-civilian technology, GPS is no longer the only choice for everyone. There are more and more multi-functional terminal devices based on the Beidou system on the market, but the existing Beidou terminal The control method is basically based on hardware control. This control method has high hardware requirements for terminal equipment, high cost, no separate control terminal, unfriendly interface, and because of hardware control, high power consumption and low efficiency; And due to various interference, suppression and other uncertain environmental factors, data loss during Beidou short message transmission
