Embodiment 2
The embodiment of the invention provides a kind of method of testing of dynamic traffic information broadcasting system; When said dynamic traffic information broadcasting system is tested; Generally comprise: to the test of the concrete operations of the key data of the broadcast singal quality of said dynamic traffic information broadcasting system, the data traffic of traffic information broadcasting transmitting terminal, the data volume of said dynamic traffic information broadcasting system, said dynamic traffic information broadcasting system and said dynamic traffic information broadcasting system; Whether the broadcast singal relationship between quality can be received by automatic navigator to the data of broadcasting; The success or failure of dynamic traffic information broadcasting system have been determined; The embodiment of the invention is at first tested the broadcast singal quality of said dynamic traffic information broadcasting system and is set forth, and as shown in Figure 3, this method comprises:
301, receive traffic information broadcasting data that said dynamic traffic information broadcasting system sends by automatic navigator and with the frequency domain audio data.
302, said traffic information broadcasting data that said automatic navigator received and analyze with the frequency domain audio data;
303, obtain the result of broadcast singal quality test according to the result of said analysis and preset broadcast singal quality test standard.
Wherein, Said preset broadcast singal quality test standard can be divided into 4 grades; But the embodiment of the invention does not limit this: when being divided into 4 grades, said preset broadcast singal quality test standard can comprise: Data Receiving is normal and broadcast singal is good, Data Receiving normal but broadcast singal has noise, data to receive but broadcast singal arranged and do not have broadcast singal.
When the practical implementation embodiment of the invention; Can be with the result of said analysis; Compare with above-mentioned 4 grades; Confirm which grade is the said traffic information broadcasting data that receive belong to, and just confirmed the test result to the broadcast singal quality of said dynamic traffic information broadcasting system, obtained the broadcast singal quality of said dynamic traffic information broadcasting system.
DARC has fixing bandwidth when carrying out the transmission of traffic information broadcasting data, for example 16kbps if the traffic information broadcasting data sending terminal does not carry out the control of active data flow, can cause bandwidth waste or loss of data.For preventing bandwidth waste or loss of data, the present invention is the test that strength also provides a kind of data traffic of the traffic information broadcasting transmitting terminal to said dynamic traffic information broadcasting system, and as shown in Figure 4, this method comprises:
401, receive the traffic information broadcasting data flow that said traffic information broadcasting transmitting terminal sends in the given time.
Wherein, In order to realize test to the data traffic of the traffic information broadcasting transmitting terminal of said dynamic traffic information broadcasting system; Said transmitting terminal can be in the bandwidth for transmission traffic information broadcasting data of preset time through acquiescence; And will send the said used time of traffic information broadcasting data and send to said data receiver, so that accomplish test to the data traffic of the traffic information broadcasting transmitting terminal of said dynamic traffic information broadcasting system.
402, calculate the data volume of the said traffic information broadcasting data flow that in the said scheduled time, receives.
403, according to said data volume and preset data volume standard; Confirm the test result of the data traffic of said traffic information broadcasting transmitting terminal; So that the result according to said test obtains the actual at present bandwidth of said dynamic traffic information broadcasting system; So that the related personnel adjusts said data transfer bandwidth, avoid bandwidth waste or loss of data.
Further, when the data volume of said dynamic traffic information broadcasting system was tested, the embodiment of the invention also provides a kind of method of testing, and was as shown in Figure 5, and this method comprises:
501, the output data quantity in the said dynamic traffic information broadcasting system scheduled time of statistics.
Wherein, said dynamic traffic information broadcasting system is when the input data, and the data volume that is generally a data transfer cycle average transmission is 57kb; When output data quantity; If dynamic traffic information broadcasting system all sends all RTIC, data volume is about 25KB, and maximum is about 28.75KB.
502, the output data quantity threshold value compares in the output data quantity that said statistics is obtained and preset said scheduled time, obtains the result to the data volume test of said dynamic traffic information broadcasting system.
Wherein, the empirical value that the output data quantity threshold value can set up on their own for the user in the said scheduled time, the embodiment of the invention does not limit this, can specifically be provided with as the case may be in the specific implementation.
Wherein, When the output data quantity threshold value compares in the output data quantity that said statistics is obtained and preset said scheduled time; Because Floating Car can not cover all RTIC in per 5 minutes; The actual data of sending should be less than 23.34KB and 26.841KB, if be less than above-mentioned two values, show that then the traffic information broadcasting data possibly go wrong in the process of sending.
Further, in the time need testing the data key of said dynamic traffic information broadcasting system, the embodiment of the invention generally adopts following method, comprising: the byte number that obtains key data; The byte number of the said key data that obtains divided by a byte number that key comprised, is obtained the key number of said dynamic traffic information broadcasting system, thereby realize test the key data of said dynamic traffic information broadcasting system.For example, 8 bytes of each key, if obtain the byte number of said key data, then the number of decidable key is: key number=byte number/8.
