Abstract
The present invention relates to a mileage counting method of a mobile network intelligent automatic path test apparatus. The method comprises the following procedures: (1) test data inputting: transmitting the test data to a TA system namely an intelligent automatic path test apparatus of the Ericsson corporation with a LOG file form by a foreground test terminal of the automatic path measuring system, and inputting into the TA system data base; and (2) confirming a test time period and a running mileage of the tested vehicle. Each test sampling point is corresponding to a test time and a latitude and longitude coordinate of this point. Each test sampling point time is in series connected to form a whole test time period of a foreground test terminal of the automatic path test apparatus. When the latitude and longitude corresponding two adjacent test sampling points are converted to distance, the running mileage is obtained by adding the distances in sequence. The invention possesses the beneficial effect that the TA test mileage can be quickly and accurately counted and the accurate measurement to network indexes of ''mileage voice missing ratio'' and the like is provided with scientific criterions.
Description
Technical field
The present invention relates to a kind of intelligent automatic road measuring device mileage statistical method in mobile network, be applicable to testing vehicle management and mobile network indicator-specific statistics, belong to test statistics method and technology field.
Background technology
The intelligent automatic road measuring device of Ericsson (TEMS AUTOMATIC abbreviates TA as) can be tested automatically, and test result is goed deep into statistics and analysis GSM, GPRS, CDMA, CDMA1x network quality.
The automatic road measuring system foreground test terminal (MTU of Ericsson, Mobile Test Unit) need be installed in and carry out the mobile network on the testing vehicle and test automatically, the rent of testing vehicle need be by the payment of test mileage number, for people under preventing testing vehicle makes a false report the rent that mileage number is gained testing vehicle by cheating, test the mileage statistics accurately with most important.
At present, add up automatic road measuring system foreground test terminal (MTU by record testing vehicle mileometer with by GIS (Electronic Map Information System) map hand dipping instrument, MobileTest Unit) promptly science is not lack of standardization yet for distance travelled, and statistics mileage number error is bigger, can not effectively manage testing vehicle.
In order to improve mobile network's network service quality, accurately measuring network indexes such as " mileage call drop ratios " will be particularly crucial, so accurate statistics automatic road measuring system foreground test terminal (MTU of Ericsson, Mobile Test Unit) distance travelled can effectively be managed testing vehicle, and can measure mobile network's indexs such as " mileage call drops than " and reflect mobile network's service quality.

Technical problem to be solved by this invention provides a kind of TA that can count fast and accurately and tests mileage, provides the intelligent automatic road measuring device mileage statistical method in mobile network of scientific basis for accurately measuring network indexes such as " mileage call drop ratios ".
The technical solution adopted for the present invention to solve the technical problems:
Method step of the present invention is as follows:
(1) test data typing:
Utilize test terminal, automatic road measuring system foreground that test data is uploaded to the intelligent automatic road measuring device that the TA system is an Ericsson with the LOG document form, and typing TA system database;
(2) determine testing time section and testing vehicle distance travelled:
Promptly being split into the test sample point behind each LOG file typing TA system database is stored in the TA system database Tsample table, each test sample point be to should there being the latitude and longitude coordinates of testing time and this point, with the contact testing time section of test terminal, the whole automatic road measuring of formation system foreground of each test sample point time; The longitude and latitude that adjacent two test sample points are corresponding is converted into after the distance distance travelled number that addition successively obtains testing vehicle again.
Spherical distance between described adjacent two test sample point A, the B calculates by following formula (A):
Arc length AB=R * ∠ AOB/ π
＝R/π×arccos[(siny
1×siny
2)+(cosy

Fig. 2 is A on the earth sphere, B point-to-point transmission odometer nomogram.
Embodiment
According to the technical scheme in the foregoing invention content part, in conjunction with software module (as shown in Figure 1), the statistician finishes on PC by mileage again.
The longitude and latitude of two adjacent test point A, B on the known earth sphere, the method following (referring to Fig. 2) of calculating sphere distance therebetween:
(1) at first in earth spherical diagram, make boost line:
A, make the limit line L of arctic point to Geophysical South Pole, limit line L passes centre of sphere O point;
B, cross vertical line AC and the BD that A, B point is made limit line L respectively, vertical point is respectively C, D;
The parallel lines that c, mistake B, C point are made CD, BD respectively meet at the E point, and get rectangle BDCE;
(2) known A, B point longitude and latitude, the length of calculating arc AB by following formula (1) are the spherical distance between A, B point:
Arc length AB=R * ∠ AOB/ π (1)
In the formula: R: the mean radius of the earth, its value is 6371Km, π: circumference ratio;
A, ask the value of the ∠ AOB in the following formula (1):
In Δ AOB, cos ∠ AOB=(OB
2+ OA
2-AB
2)/2 * OB * OA
Because OA=OB=R gets OA=OB=R substitution following formula:
cos?∠AOB＝(2R
2-AB
2)/2R
2 (2)
B, ask the AB in the following formula (2)
2:
Because plane ACE is vertical with plane AEB, so Δ ABE is a right-angled triangle,
In Δ ABE, AB
2=AE
2+ BE

Because BE=CD=OD+OC gets BE=OD+OC substitution following formula:
AB
2＝AE
2+(OD+OC)
