Description
Technical field
The present invention relates to onboard satellite communication system.Belong to the communications field.
Background technology
Car-mounted terminal is that current Ministry of Communications carries out with all strength, the monitoring device must installed on " two visitor one danger " vehicle.It
Can the real-time longitude and latitude of vehicle, speed, course, various warning amount and picture voice data be uploaded on supervising platform,
By supervising platform, vehicle is carried out management and control.
It is by GPRS network that data report supervising platform, but when driving, vehicle travels and covers in GPRS network
Cover less than regional rural, hill path, the area such as desert, just cannot be by information reporting to supervising platform.
The solution of main flow in the market is:
To store without the data in network's coverage area, wait to drive to the region of network
Data are uploaded in the lump.
Do so brings two problems:
1, data delay.Critical data can not be uploaded to manage platform in time, such as collides, rollover etc., affects rescue adversely.
Travelling in the region not having the network coverage for a long time, can preserve mass data, data are easily lost；Or when batch is uploaded
Between long, data volume is excessive, causes this month flow to be uprushed.
Summary of the invention
The present invention is to solve existing vehicle without under GPRS communication network, affecting data and upload in real time and vehicle data
The problem lost.Now provide without the onboard satellite communication system under GPRS communication network.
Onboard satellite communication system under communication network without GPRS, it includes that vehicle-mounted terminal system, big-dipper satellite, ESD protect
Protect unit, SD card, voice-output unit and display unit,
Vehicle-mounted terminal system uses processor to realize,
The signal of communication input/output terminal of vehicle-mounted terminal system connects the signal of communication input/output end of big-dipper satellite,
The protection signal input/output terminal of vehicle-mounted terminal system connects the protection signal input/output end of ESD protected location,
The storage signal input/output terminal of vehicle-mounted terminal system connects the storage signal input/output end of SD card,
The voice signal input/output terminal of vehicle-mounted terminal system connects the voice signal input/output end of voice-output unit,
The display signal input/output terminal of vehicle-mounted terminal system connects the display signal input/output end of display unit.
According to without the onboard satellite communication system under GPRS communication network, being embedded with control software inside processor, this control is soft
The flow process of part is:
Step one, judge whether vehicle can detect and receive GPRS signal, if it is, perform step 2, if
No, then perform step 3；
Step 2, vehicle carry out GPRS communication；
Step 3, use big-dipper satellite to communicate, when big-dipper satellite set up with vehicle port signal be connected time, vehicle passes through
Big-dipper satellite, it is thus achieved that the data in the course of the longitude and latitude of vehicle, the speed of vehicle and vehicle, and resolve；The number that will have resolved
According to being sent to big-dipper satellite, perform step 4；
Step 4, by big-dipper satellite by satellite-signal by the data in the course of the longitude and latitude of vehicle, the speed of vehicle and vehicle
It is sent to display unit show, provides voice message to voice-output unit simultaneously, and information of vehicles real-time storage is existed
In SD card.
Beneficial effects of the present invention: use big-dipper satellite to communicate with vehicle-mounted terminal system, uses ESD protected location simultaneously
Carry out ESD antistatic protection, big-dipper satellite can Real-time Collection current time and information of vehicles, by real-time for this signals of vehicles
It is sent to manage platform carry out showing and voice message, uses which to carry out in real time with collecting vehicle information, the data of collection
Store in SD card, and data will not be lost, it is possible to grasp the state of vehicle in real time.
