Machine global reliability.
Specifically, a kind of shown referring to Figures 1 and 2, statistics based on GNSS receiver dialing procedure provided by the invention
Method includes the following steps：
Step S1, the boot-strap circuit on all GNSS receiver mainboards to be measured is subjected to short circuit.Specially：First using interior
Hexagonal screwdriver comes loose 6 screws of GNSS receiver upper cover, and GNSS receiver upper casing is taken down, by boot-strap circuit on mainboard into
Row short circuit is then reinstalled GNSS receiver upper casing.
Step S2, firmware upgrade is carried out to all GNSS receivers to be measured.Use GNSS receiver serial port data line serial ports
Computer serial port is connected to, double-clicks and runs firmware upgrade procedure, after prompt message to appear, foot is filled in receiver bottom battery storehouse
Electronic power batteries are powered using Serial Port Line DC power supply ports, and Auto Power On, firmware upgrade procedure progress bar start to dodge receiver immediately
It is bright, after the completion of prompting upgrades, shutdown.
Step S3, the input terminal of tester connection U is turned into string equipment to produce multiple serial ports, and use can power respectively
Each serial ports that each GNSS receiver is turned string equipment by data line with U is connected.In an optional embodiment of the invention, tester
For computer；The data line that can power is the data line that can power in two generations.
Step S4, the power supply head for the data line that can power is connected respectively using attaching plug output terminal more than one point, and will be for
The feeder ear of the attaching plug of electric data line connects a programmable power supply output terminal, when setting the energization of a cycle by programmable power supply
Between and power-off time control the conduction time of each GNSS receiver and power-off time.One is enumerated with regard to this step below in detail to implement
Example is described in detail：
Programmable power supply is first turned on, clicks top Timer buttons, left side liquid crystal display clicks time set --- timing is joined
It counts, voltage 12V, electric current 5A in the keyboard setting sequence 0 of use right side, time 120S, voltage 0V in sequence 1, electric current 0A, the time
10S.Output group number is then clicked on, setting output group number is 2, then clicks 1/3 button and switches to lower one page, selects cycle group
Number inputs the group number of setup test, such as 100, save button is clicked after being provided with, and clicks browser, and selection preserves, and utilizes
Right side input through keyboard profile name, such as TEST20151218 are clicked and are preserved, and prompt Overwrite existing files, are selected " confirmation ",
After being provided with, Timer button timeing closing patterns, then electric bright Timer buttons opening timing pattern can be clicked directly on, again
Timer button is clicked, treats that " timing is opened will change channel output values to screen prompt, if continue", it clicks and confirms, subsequent point
Beating keyboard ON/OFF buttons, screen start countdown, and each output terminal starts normal power supply.Optionally, programmable power supply is direct current
Source, and programmable power supply device control unit point or whole GNSS receiver timing cycles open and close.
Step S5, PC ends are opened and receives statistical tool, connected GNSS receiver respectively and connect serial port, set test
