Implement.In other examples, in order to avoid confusion with the present invention, for some technical characteristics well known in the art not into
Row description.
In order to thoroughly understand the present invention, detailed step and detailed structure will be proposed in following description, so as to
Illustrate technical solution of the present invention.Presently preferred embodiments of the present invention is described in detail as follows, however other than these detailed descriptions, this
Invention can also have other embodiments.
Shown in referring to Fig.1, the present invention provides a kind of test method for changing frequency based on GNSS receiver radio station, mainly for
Radio station changes the automatic Verification of frequency success or not, and manual setting receiver is radio station mode, passes through receiver under the mode of radio station
Order write-in frequency of radio station, after being written successfully, leads directly to radio station plate, directly acquires radio station parameter by the order in radio station itself, look into
See whether the frequency of the frequency and setting that get is consistent.Test method provided by the present invention includes the following steps:
Step 1 carries out hardware modifications to GNSS receiver, specially is adapted as powering on automatically by GNSS receiver hardware,
When GNSS receiver receives the electric current of external equipment output, GNSS receiver Auto Power On.It is optional real in the present invention one
It applies in example, which is programmable power supply.Further, the programmable power supply of direct current can be selected.
It will be connected to the external equipment with timed startup/shutdown function with GNSS receiver, external equipment time switch be set
The machine time simultaneously powers to GNSS receiver, after external equipment booting, GNSS receiver Auto Power On；
Step 2 carries out test environmental structure.Specifically: one end of a test device is connected by serial server
GNSS receiver, the other end are connected with the end PC, and pass through serial port setting radio station parameter.Here, we can be by programmable power supply
It is connected with GNSS receiver, and the programmable power supply timed power on/off time is set at the end PC, powers to GNSS receiver, work as program-controlled electric
After the booting of source, GNSS Auto Power On.
Step 3, radio station module initialization setting.Specifically: after GNSS receiver booting, the starting of radio station module, test dress
After setting starting, the time of the test device energy automatic identification radio station module initialization, and can be carried out corresponding judgement, when radio station module
After initializing successfully, it can be carried out radio station and write frequency operation, continue to judge in next step；When radio station module initialization failure, energy
It is restarted automatically, and the information of radio station module initialization failure is saved.
Step 4, receiver order write frequency.Specifically: one station list (1-9 channel) of setting receives toward GNSS
Given frequency of radio station is written in machine one by one, test device sends the order for changing frequency to GNSS receiver, when radio station receives this
After order, corresponding frequency modification operation is carried out, and after write frequency, function must be obtained using test device and obtain frequency
Whether rate is written success: when getting frequency of radio station, test device can judge automatically into next step, when acquisition is less than radio station
When frequency, it is restarted automatically and saves the acquisition information.
Step 5, radio station order obtain radio station parameter.After completing step 4 and pass through GNSS receiver order write-in electricity
After platform frequency, test device can send the order of straight-through radio station plate, and under the direct mode operation of radio station, test device is called inside radio station
Order obtain current frequency of radio station information, when the frequency of radio station got is consistent with the frequency of radio station of setting, test dress
Set and counted: when the frequency of radio station of the frequency of radio station and setting that get is inconsistent, test device can make warning note,
Then it is restarted automatically and saves acquisition information.
Step 6, export test report.Repeated switching is multiple, and test device constantly repeats to write frequency, reads frequency operation,
And the information operated every time is saved in real time；After test device end of run, in the test device programming count test process
Radio station module initialization failure ratio, receiver order write-in failure ratio, radio station order obtain success rate and/or radio station order
Obtain failure ratio.In the present invention, in order to guarantee the accuracy of test data, we have repeated switching at least 80 times, such as instead
Multiple switching on and shutting down 100 times, software constantly carries out writing frequency, reads frequency operation, and saves the information operated every time in real time, when software is run
After, in software meeting programming count test process, radio station module initialization failure ratio, receiver order write-in is unsuccessfully compared
Example, radio station order obtain success rate, and radio station order obtains failure ratio.
It is proposed of the invention largely solves test radio station and changes the difficult method of frequency, can be automatic by the software
The frequency of radio station provided is read and write, and is judged.In a large amount of switching on and shutting down test, software, which can automatically analyze, changes frequency success rate.
It, can cracking differentiation radio station module performance quality by means of the partial data.This brings great convenience to tester.
Presently preferred embodiments of the present invention is described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, devices and structures not described in detail herein should be understood as gives reality with the common mode in this field
