The satellite-signal of CMMB uses S-band 2.635～2.660GHz to cover, and the urban ground signal uses U wave band 470～798MHz to cover, and CMMB is covered as the master with the urban ground signal at present.For MBMS service is provided better, all need system is carried out a series of test at construction and the run duration of CMMB, such as signal coverage rate and signal strength signal intensity etc. are measured, and improve based on test result.
At present, the terminal equipment that adopts in CMMB signal testing process has following defective:
At first, the testing equipment complex structure usually need be by testing after PC or the notebook install software; Secondly, waste of manpower needs two people usually at least when carrying out drive test, and a people drives, and a people does test; Once more, higher to tester's competency profiling, need do the training of software operation, the driver also needs test segment familiar; At last, test result need be drawn coverage diagram, complicated operation in conjunction with third party's map datum.
Summary of the invention
In order to solve the problem that runs in the current C MMB signal testing process mentioned above, the present invention designs on the hardware foundation of existing portable GPS navigation instrument again, and a kind of portable mobile multimedia signal-testing apparatus is provided.
The technical solution used in the present invention can be described as:
A kind of portable Mobile Multimedia Broadcasting testing apparatus, comprise housing, be arranged on the liquid crystal touch screen on the housing, and be installed in circuit part in the housing, wherein circuit part comprises microprocessor module, and the memory module that is connected with described microprocessor module, driver module, signal acquisition module and GPS module, wherein signal acquisition module gathers and analyzes the signal strength signal intensity of Mobile Multimedia Broadcasting in real time, the real-time gathering geographic position information of described GPS module, the output information of described microprocessor module received signal acquisition module and GPS module is also used analysis-by-synthesis software and the engine map be stored in the memory module, by driver module at the signal strength values that shows the present position on the liquid crystal touch screen in real time and simultaneously at the punctuate that on map, carries out different colours according to signal strength values.
As a kind of improvement of above technical scheme, this system uses WinCE 6.0 operating systems.
As a kind of improvement of above technical scheme, this device files the data of test automatically, is directly drawing CMMB signal coverage diagram on the map and is preserving image file in storage module in conjunction with test path and test data simultaneously.
The invention has the beneficial effects as follows:
The present invention runs on the WinCE platform on the microprocessor in that a kind of portable Mobile Multimedia Broadcasting testing apparatus is provided, and built-in navigation system uses software that the mobile multimedia signal is carried out sample analysis, will bring following benefit thus:
A) testing equipment is portable, need not just can build test environment by extra hardware device;
B) level of integrated system height, test operation is simple, and training that need not be special just can begin test job by specification in 2 minutes;
C) because the convenience of operation only needs a people to drive away just can test, saved manpower;
D) can carry out path planning by navigator for remote districts, also not influence test even the driver is unfamiliar with the highway section;
E) the test coverage diagram is directly drawn on the map of navigation, need not manually synthesize, and is directly perceived, convenient, comes into plain view.
Description of drawings
Fig. 1 is a schematic diagram of the present invention;
Fig. 2 is the structural representation of one embodiment of the present of invention.
Embodiment
As illustrated in fig. 1 and 2, a kind of portable Mobile Multimedia Broadcasting testing apparatus proposed by the invention, it comprises housing, be arranged on the touch-screen on the housing and be installed in the interior circuit part of housing, described circuit part comprises microprocessor module 1 and the memory module 2 that is connected with microprocessor module 1, driver module 3, signal acquisition module 4 and GPS module 5, wherein signal acquisition module 4 gathers and analyzes the signal strength signal intensity of Mobile Multimedia Broadcasting in real time, and the result is input to microprocessor module 1; GPS module 5 real-time gathering geographic position information, and equally the result is input to microprocessor module 1.The object information of microprocessor module 1 received signal acquisition module 4 and GPS module 5 and combination are stored in analysis-by-synthesis software and the engine map on the memory module 2, by driver module 3 real-time signal strength signal intensity and cartographic information that shows the present position on liquid crystal touch screen, and simultaneously at the punctuate that on map, carries out different colours according to signal strength values.This system operates on the embedded OS WinCE 6.0, and after test is finished, automatically the data of this test are filed, directly drawing CMMB signal coverage diagram on the map and preserving image file in storage module 2 in conjunction with test path and test result simultaneously.
Wherein microprocessor module 1 and the operating system, analysis-by-synthesis software and the engine map that are stored in the memory module 2 have been formed core of the present invention-analysis-by-synthesis module.
Consider and exist the portable GPS navigation solution that operates in a large number on WinCE 6.0 operating systems on the present market, in the present invention, this portable Mobile Multimedia Broadcasting testing apparatus serves as the basis and is improved that with the solution of portable GPS the Atlas-IV solution of the U.S. SiRF company of the market mainstream just becomes the first-selection of present embodiment like this.Described Atlas-IV chip has been integrated with GPS baseband chip and rear end main control chip, and official's firmware is provided, and only needs to add the GPS radio-frequency front-end and has just formed complete hardware and firmware GPS solution.Its rear end main control chip adopts ARM11 dual core processor framework, supports the smoothness operation of WinCE6.0.In addition, consider portability and resolution, display module has in the present embodiment been selected one 4.8 inches liquid crystal display screen for use, considers the specificity of cost and this equipment, memory module is selected the built-in Flash storage of 2G for use, and external micro SD memory card interface is provided simultaneously.Certainly, it is also indispensable to be used for being connected with computer the USB interface of upgrade-system and software.In sum, this device can be considered as adding based on existing portable GPS navigation instrument a kind of improvement of CMMB signal acquisition module and related software on certain angle.
