Detailed description of the invention
Fig. 1 is Dynamic Host Configuration Protocol server Establishing process figure in electric power acquisition terminal network interface detection method of the present invention.
Fig. 2 is the overhaul flow chart of electric power acquisition terminal in electric power acquisition terminal network interface detection method of the present invention.
Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
Fig. 1-2 shows the flow diagram of the application electric power acquisition terminal network interface detection method.This method includes,
Step 1 builds dhcp client；
Step 2 receives the detection network interface order from main website, according to random number dynamic generation MAC Address, sends IP address
To Dynamic Host Configuration Protocol server, the Dynamic Host Configuration Protocol server is built on the router for application, the Dynamic Host Configuration Protocol server limitation distribution IP network section, if
Set address lease；
Step 3 judges whether the IP address obtained is legal IP in step 1 in IP network section, if so, record test knot
Fruit success, network interface is working properly, executes step 4, if it is not, then recording test result failure, executes step 4；
Test result is written in file system step 4.
In this application, to guarantee that router does not conflict with LAN IP generation, the router is only whole with electric power acquisition
End connection；Meanwhile the electric power acquisition terminal in step 2 is linked into the router for successfully building Dynamic Host Configuration Protocol server, and will be described
The debugging serial ports of electric power acquisition terminal is linked into the hyper terminal of PC main website, and network interface order is tested being assigned by main website.
Specific to the present embodiment, which passes through the lan address of PC machine access router on web, and opens
The DHCP function of opening router is established, meanwhile, the pond the IP range of router is changed to single network segment, i.e., can be accommodated simultaneously
255 electric power acquisition terminals are tested simultaneously, to improve testing efficiency.Certainly, the electric power acquisition accessed when same batch is tested
Terminal number can determine according to actual needs.To guarantee that Dynamic Host Configuration Protocol server has enough IP that can be used to distribute, in the step 2
The router address rental period be 5min, i.e. 5min after distribution IP can recycle IP, guarantee that next round test has enough IP
For distribution.
In the application, judge whether the IP address obtained is legal IP in step 1 in IP network section in the step 3, if
It is then to record test result success, network interface is working properly, it specifically includes:
Step 31 judges whether there is IP address return, if so, step 32 is executed, if it is not, executing step 33；
Step 32 judges whether the IP address is legal IP in step 1 in IP network section, if so, executing step 34；
Step 33 judges whether request timed out, and carries out respective operations；
Step 34 judges whether to have applied for n times, if so, record test result success, network interface work normally, conversely,
Jump the application IP address and step 3 executed in step 2.The value of the N, time-out time setting determine as needed.In this reality
It applies in example, the N value is 3, and time-out time is set as 10S.
In specific deterministic process, judges whether request timed out in the step 33, and carry out respective operations, is corresponding with:
Judge request timed out, then follow the steps 4, executes step 31 conversely, jumping.
To guarantee to conflict with batch MAC Address of the electric power acquisition terminal of test, the electric power acquisition terminal is according to end
The unique sequence numbers and current system time of ESAM security module generate random number as random number seed respectively in holding, by this
Two random numbers are combined into MAC Address, specifically, in the step 2 according to random number dynamic generation MAC Address, it is corresponding
Are as follows:
Step 21, the electric power acquisition terminal generate one at random according to built-in ESAM security module unique sequence numbers
Number；
Step 22, the electric power acquisition terminal generate a random number according to the current time in system；
Random number obtained in step 21 and step 22 is formed MAC Address immediately by step 23, the electric power acquisition terminal,
And Ethernet driving is written.The fixed write-in number 2 of first of the MAC Address, what the second to four write-ins were generated by step 22
Random number, the five to six write-in is by random number that step 21 generates to generate random MAC address.
To guarantee that test process does not influence the ether network parameters of electric power acquisition terminal, execute basis in the step 2 with
Before machine number dynamic generation MAC Address, following operation has also been carried out:
Ether network parameters are stored and are caused in file system by S20, the electric power acquisition terminal.
Meanwhile before executing the application IP address in the step 2, following respective operations have also been carried out:
Illegal value is written in itself current IP by S24, the electric power acquisition terminal, and the illegal value is not belonging in step 2
IP in IP network section, and itself current IP is written in Ethernet driving.It can prevent the Ethernet of electric power acquisition terminal from driving in this way
There are legal IP to cause to judge by accident in dynamic, it is ensured that as long as electric power acquisition terminal obtains IP address, which must come from DHCP
Router.
The present processes have also carried out following operation after executing the step 4:
The ether network parameters that S5, the electric power acquisition terminal are stored into file system after the completion of test are written back to terminal
In trawl performance；
3 test results being written in file system are uploaded to master by debugging serial ports by S6, the electric power acquisition terminal
It stands.
The application is correspondingly arranged Dynamic Host Configuration Protocol server and dhcp client in router and electric power acquisition terminal room, is adopted by electric power
It is leading to collect terminal, by DHCP protocol to Dynamic Host Configuration Protocol server dynamic application IP, can ensure that the IP that each terminal obtains is different, and energy
Multiple electric power acquisition terminals are tested in the same time, liberate main website pressure, it is made to be only used for issuing detection network interface order,
Improve automatic test efficiency；Using the unique sequence numbers of terminal ESAM security module and present system time as random number
Seed generates random number respectively, it can be ensured that each terminal has different MAC Address, it is ensured that MAC Address does not conflict, and further protects
Hinder the high efficiency of test；IP address cleverly can be received using network interface, then it represents that network interface can work normally, it is on the contrary then cannot
Mode easily solves network interface detection problem, without in addition setting terminal parameter, is not necessarily to manual intervention, operating in a key is convenient
Fast, time saving and energy saving province's process, substantially increases detection efficiency.
Other than above-mentioned improvement, other similar improvement are also contained in improvement threshold of the invention, herein just no longer
It repeats.Although an embodiment of the present invention has been shown and described, it will be appreciated by those skilled in the art that: do not departing from the present invention
Principle and objective in the case where can to these embodiments carry out it is a variety of variation, modification, replacement and deformation.
