Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] The present invention adopts following technical scheme as:

[0026] Install the virtual user machine software on any computer, and the computer becomes a virtual user machine, and the Beidou user terminal is connected to the virtual user machine through a serial port or a network port to form a RDSS communication resource pool.

[0027] The virtual client computer software includes a user terminal interface module, a user terminal resource management module, a user terminal state management module, a communication message sending control module, and a long message splitting control module.

[0028] 1. User terminal interface module

[0029] The virtual user machine is connected to the real Beidou user equipment through network communication or serial port communication protocol, and uses the scalable protocol processing framework to package the current main Be...

Abstract

The invention discloses a Beidou user terminal communication resource sharing system. Virtual client software is installed on a computer; the virtual client software includes a user terminal interface module, which is connected to the Beidou user terminal through network communication or serial port communication protocol; the user terminal The resource management module uses the dynamic linked list to record and manage the connected Beidou user terminal resources; the user terminal status management module obtains the sending status of the user equipment; the communication message sending control module realizes the interaction with the user or the upper application system; the long message splitting control The module splits the long message sent by the user, and the split communication message is transmitted to the corresponding user terminal according to the interface protocol of the user terminal recorded in the resource link list to complete the sending. The invention can shorten the time interval of sending messages, increase the length of sending messages, and realize high-frequency and long sending of messages by users.

Description

technical field [0001] The present invention relates to global navigation satellite systems In the field of application technology, it particularly relates to a system for sharing communication resources of Beidou user terminals based on the Beidou RDSS (Radio Determination of Satellite Service) system. Background technique [0002] Beidou short message communication is a unique function of the Beidou system RDSS service system, and it is also an important feature that distinguishes Beidou from the GPS system. The advantages of being wide and free from environmental and geographical restrictions have become the first choice for users in areas where ground communication networks cannot cover areas such as civil secret-related industries, key areas, remote and maritime areas, especially when performing tasks such as emergency rescue and disaster relief, stability maintenance and emergency management, and border control. , using Beidou communication as the main means of emerg...
