Abstract
The invention discloses a mobile digital television with a navigation system, which comprises a mobile digital television receiver. The mobile digital television with the navigation system is characterized in that: a circuit board of the mobile digital television receiver is provided with a receiving module, a transmitting module, an unlimited electric tuning converter, a control module, a calculating module and a storage module of the information and the data of a Galileo system, wherein the storage module stores an electronic map; the receiving module receives the data and the information appointed by a satellite under the control of the control module; the data information generated after the calculating module calculates is stored in the storage module; and then an electronic map is generated and can be displayed on the mobile digital television receiver. The mobile digital television with the navigation system has the advantages of combining the navigation system and the mobile digital television integrally without limitation to a GPS, strong navigation signal and high positioning accuracy.
Description
Technical field
The present invention relates to a kind of mobile digital television with navigation system.
Background technology
At present, people are at bus, often all a mobile digital television can be installed on the taxi, also can be equipped with GPS band guider onboard, the two generally all separates, so both wasted system equipment resource, also to take certain space, and gps system is that military use is done in design, keep the signal strength signal intensity that can limit GPS because of the U.S., accuracy, and the power that whole group system is closed, therefore when the U.S. gets involved certain great war, among the peoplely might can't use GPS, also have U.S. government just to begin to relax the restriction of use gps system among the people, so be subject to many limitations in the use in 2000.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of this invention is to provide and a kind of navigation system and mobile digital television are united two into one, and be not subjected to the restriction of gps system, navigation signal intensity is strong, the mobile digital television that positional accuracy is high.
Purpose of the present invention is achieved through the following technical solutions.
A kind of mobile digital television with navigation system, comprise the reception of Mobile Digital TV machine, it is characterized in that: the circuit board of described reception of Mobile Digital TV machine is provided with the receiver module of Galileo system information and date, transmitter module, unlimited electric tuning transducer, control module, computing module, storage module, receiver module is electrically connected with control module by unlimited electric tuning transducer, computing module, storage module is electrically connected with control module, receiver module is electrically connected with computing module by storage module, wherein unlimited electric tuning transducer is used to change the reception and the tranmitting frequency of antenna, the storage module internal memory contains electronic chart, receiver module receives satellite data designated and information under the control of control module, module is calculated the longitude that the back produces as calculated, latitude, time and related data information are stored in the storage module, produce one then and mark the reception of Mobile Digital TV machine at electronic chart the map picture and the map picture of positional information can show in the reception of Mobile Digital TV machine at that time.
Describedly contain alert audio information at the storage module internal memory, in the mobile digital television of band navigation system, also be provided with alarm switch, under the alarm switch open mode, the reception of Mobile Digital TV machine sends alarm sound, under the control module effect map picture is sent to another terminal through transmitter module simultaneously.
The panel of described mobile digital television is provided with alarm button, switching button and navigation function button.
The present invention compared with prior art has the following advantages:
The present invention is owing to be provided with the receiver module of Galileo system information and date on the circuit board of reception of Mobile Digital TV machine, transmitter module, unlimited electric tuning transducer, control module, computing module, storage module, receiver module is electrically connected with control module by unlimited electric tuning transducer, computing module, storage module is electrically connected with control module, receiver module is electrically connected with computing module by storage module, wherein unlimited electric tuning transducer is used to change the reception and the tranmitting frequency of antenna, the storage module internal memory contains electronic chart, receiver module receives satellite data designated and information under the control of control module, module is calculated the longitude that the back produces as calculated, latitude, time and related data information are stored in the storage module, producing one then marks display device at electronic chart the map picture and the map picture of positional information can show in display device at that time, therefore navigation system and mobile digital television are united two into one, like this, television set not only has the function that televiews, also with navigation function.Galileo system mainly is for civilian in addition, the gps system of doing military use with design is different, because of the U.S. keeps signal strength signal intensity, the accuracy can limit GPS, and the power that whole group system is closed, therefore get involved certain great war when the U.S., among the peoplely might can't use GPS.Also have, U.S. government is the restriction that just began to relax use gps system among the people in 2000.In theory, the Galileo system in Europe is can all not smoke system resource to do military use, and can provide result more accurately than GPS, complete when open to system, will open the army and the people that give the whole world uses jointly, adopt in the gal and slightly can not disturb with gps system as sideband (sideband) signal, in fact be that complementarity is higher than competitiveness between the mobile digital television of two satellite band navigation system, Galileo system uses 30 satellites at 3 orbit planes, sends signal with gps system is the same in the L1 frequency range.China adds " Galileo plan " in September, 2003, therefore no longer is subject to many limitations in the use, makes signal strength signal intensity stronger, and positional accuracy is higher.Therefore, in case somewhere go wrong, the user just can send signal to platform by Galileo system, and the people who rescues like that just can in time implement rescue by the position that shows on the platform.
