Abstract

The invention provides a three-system network data communication module. The three-system network data communication module is characterized in that in an embedded board card and a real-time Linux operating system, three 3G communication modules and three built-in high gain antennas corresponding to three-system communication networks are embedded, wherein the three 3G communication modules include TD-SCDMA, WCDMA and CDMA2000; the three 3G communication modules are connected with the embedded board card through a high speed USB bus. By the application of the three-system network data communication module, the problems that in the mobile communication application process, due to the fact that relay signals with different systems can hardly cover the whole process of transmitting mobile application real-time data, the real-time communication process can be interrupted unpredictably, and the defects of actual application are caused can be solved.

Description

3G tri-standard 3 passage TCP network data Intelligent communication modules

Technical field:

The present invention relates to the communications field, relate in particular to the moving communicating field of WCDMA, TD-SCDMA, CDMA2000.

Background technology:

At present, the mode based on 3G network communication concentrates on a certain standard (TD-SCDMA or WCDMA or CDMA2000) of three kinds of 3G standards.For mobile application, because the repeating signal of different systems is difficult to cover the whole mobile transmitting procedure of applying real time data, can cause unpredictable interruption in real-time communication process, cause the defect of practical application.

For example, in the time adopting single mode 3G as WCDMA mode, inevitably can run into the signal blind zone of WCDMA, even if now there is other 3G mode signal to cover (as TD-SCDMA or CDMA2000), still can produce because of not having network to connect the Transmission of real time data.

Summary of the invention:

In view of this, object of the present invention is to utilize the different field intensity of multi-modulation scheme 3G to cover, a kind of brand-new 3G tri-moulds (standard) stand-by heat TCP Data Communication in Computer Networks module is provided, by setting up the real-time connection of multiple 3G, and provide multiple preference policy, thereby in real time uninterrupted communication is provided, and meets the demand to low-power consumption in Portable movable transfer of data situation.

Another object of the present invention proposes a kind of three standard network data communication methods exactly, when mobile terminal is in the time carrying out transfer of data, mobile terminal can, according to the standard of speed, rate situation and the user preset of the 3G network real-time signal strength under the standard of three kinds of regions, the test of Ping bag, preferably be selected a 3G network and carry out communication in real time.

To achieve the object of the present invention, the invention provides under the embedded board of high-performance low-power-consumption technical grade and real-time Linux operating system embedded 3 kinds of 3G communication modules (TD-SCDMA+WCDMA+CDMA2000), and corresponding 3 built-in high-gain aerials.3 3G communication modules are linked and are connect by high speed USB bus and embedded board.

The unified api interface of realizing 3 3G modules calls, and utilizes 3G network communication function, sets up in real time TCP separately, and in stand-by heat mode of operation.

Realize the optimization algorithm that different networks connects and switches, select the most stable, the most efficient real-time network transmission channel.

Realize external power supply and carry two kinds of supply power modes of large-capacity polymer battery, meeting the long-term current demand using of portable low power-consumption.

Embodiment:

For making object of the present invention, technical scheme and technique effect clearer, below in conjunction with the accompanying drawings and the specific embodiments this aspect is described in further detail.

Fig. 1 tri-mode mobile terminal schematic diagrames.Referring to Fig. 1, known:

Three mode mobile terminals embed TD-SCDMA, WCDMA, tri-kinds of communication modules of CDMA2000.

Fig. 2 is the schematic diagrames of three mode mobile terminals under the real net environment of 3 kinds of standards.Referring to Fig. 2, known, for mobile application, because the repeating signal of different systems is difficult to cover the whole mobile transmitting procedure of applying real time data, if while at this moment adopting single mode 3G as WCDMA mode, inevitably can run into the signal blind zone of WCDMA, even if now there is other 3G mode signal to cover (as TD-SCDMA or CDMA2000), still can produce because of not having network to connect the Transmission of real time data, can cause unpredictable interruption in real-time communication process, cause the defect of practical application.Same while adopting other single modes 3G as the mode of TD-SCDMA or CDMA2000, also can run into the identical problem because of affiliated standard signal blind area, cause the interruption of transfer of data in the time carrying out real-time Data Transmission.

Fig. 3 is three mode mobile terminal workflow diagrams.As shown in Figure 3, in the time that three mode mobile terminal systems start, mobile terminal can be set up WCDMA simultaneously, TD-SCDMA, CDMA2000TCP network connects, and record connection status, according to the real-time signal strength of different systems 3G, the corresponding speed of Ping bag test, the preferred standard of rate situation and user preset, the 3G channel selecting of different priorities is provided in real time, when using according to reality, terminal use need to carry out the selection of data communication standard, under preferred standard, carry out data communication, if user demand does not change, user can use selected preferred standard to select always.If during disconnecting, three mode mobile terminals can re-establish connection, until connect re-establish; If during, user needs prepreerence standard that change has occurred, and three mode mobile terminals can re-start selection, preferably connect.So far, three mode mobile terminals can remain the optimum state that network data connects.

Fig. 4 is three mode mobile terminal module frame charts.As seen from Figure 4, mobile terminal is by embedded industry control CPU, display screen, internal memory, the solid state hard disc of SATA interface, SD card, battery/power source duplicate supply system, GPS, camera, WIFI, scanner, bluetooth, infrared, RFID, Ethernet interface, the functional module compositions such as RFID, TD-SCDMA, WCDMA, the performance parameter that CDMA2000 module connects to embedded industry control CPU transmission data network by usb bus interface, embedded industry control CPU is according to receiving to obtain the real-time signal strength of different systems 3G, the corresponding speed of Ping bag test, according to the preferred standard of rate situation and user preset, the data of network are connected and carried out preferably, and feed back to terminal use by display screen and select.

Known according to Fig. 5, after patient calls for help, hospital receives 120 notice, send ambulance, ambulance is received after patient, measures as required patient's vital sign data, in ambulance driving process, Medical mobile data collection station collects vital sign data from custodial care facility, sends in real time share service device by 3G network, and hospital's Emergency Medical Dept. receives the real-time vital sign data of patient on ambulance by network from share service device; Can carry out the communications such as voice and video by 3G network and Emergency Medical Dept. doctor with Medical mobile data collection station with Che doctor simultaneously.

The foregoing is only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of doing, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
