All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
And (3) Android operating system: in 11 months 2007, Google introduced the mobile operating system Android, and stated that Android is the first truly open and complete mobile operating system created for mobile terminals. Since then, mobile phones and tablet computers based on the Android system appear in succession, and the open source advantage of the Android system is increasingly highlighted. The Android system is composed of a Linux kernel, a system running library, an application program frame and an application program. In China, more and more systems are designed and developed based on the Android platform, and meanwhile, more and more users prefer the systems.
Beidou satellite navigation system: the Beidou second satellite navigation system is a global satellite navigation system independently developed in China, and mainly provides three functions: short message communication, positioning navigation and time service.
The Beidou satellite navigation system comprises an RDSS system and an RNSS system and serves satellite radio services determined by user positions. In satellite navigation positioning, by receiving navigation signals under an RNSS system, position, navigation speed and navigation parameter calculation is automatically completed, and passive positioning is realized; the functions of positioning, communication, position reporting and the like of the user are realized by receiving signals under an RDSS system.
The RNSS is a Radio Navigation Satellite service, which is used for autonomously completing the distance measurement of at least 4 satellites and calculating the position, the speed and the Navigation parameters of a user.
RDSS is another Satellite Radio measurement Service, and distance measurement and position calculation from a user to a Satellite cannot be independently completed by the user, and must be completed by an external system through the response of the user. The method is characterized in that the user response is used for completing the positioning and the user position report to an external system, and the integration of the positioning and the communication can be realized, so that the NAVCOMM integration in the same system is realized.
At present, the application of the Beidou navigation system is mainly in the aspect of a special system, the Beidou navigation system is used for an Android system, and data processing of Beidou navigation is also realized in special app. For general map software and navigation software, the positioning by using the Beidou satellite navigation system is basically impossible.
The embodiment of the invention provides a Beidou data communication system based on an Android operating system, which realizes the capability of ensuring positioning communication in a special environment, and adopts the following technical scheme:
a serial port communication mode is adopted between the Beidou host and the Android operating system, and the Android operating system receives the Beidou data, performs subpackage processing and distinguishes RNSS data and RDSS data. The positioning service is used for providing Android internal system service and directly providing an interface for an Android application layer for related application programs; and the communication data of the RDSS is registered to the system broadcast through the newly-added Beidou communication service. The application program needing to use the RDSS only needs to create a system broadcast receiver, and the RDSS data can be received and further analyzed. When the application program needs to autonomously acquire Beidou data, after the Beidou protocol is spliced in application software, the Beidou communication service is directly called to send the data to the bottom layer Beidou host. The integral framework of the Android operating system-based Beidou data communication system is shown in fig. 1.
In the RNSS data channel, the navigation data is analyzed and extracted to be sent to positioning service, any application program developed by using the general Android SDK, such as Baidu maps, Gaode maps and other software, can be directly installed, and then the Beidou positioning navigation data can be used for completing positioning and navigation functions.
