(11) otherwise, system directly returns above-mentioned steps (6).
In the middle of reality is used, centralized for realizing, program adopts and hairdo is carried out, main solution is according to the starting symbol of setting in advance and finishes number to generate a plurality of processes, each process is all carried out similar concrete test code, and shared data between the whole process and employing synchronously is that the mode that the V of system memory shared and file are locked realizes.A problem is that every computer has only one or two network interface cards, should how to connect the good PC of management of many Modem and rational and orderly and the communication between each Modem simultaneously? solution is exactly that each VLAN mouth of Modem and switch is linked to each other.Program then links to each other with the VLAN mouth of switch by each virtual network port of Linux.Since whole system need test that up-downgoing speed function under each distance and indication test finish display result, so increased a bright dark situation that controller board comes the simulation of command range and the LED lamp that control shows test results.Concrete production test procedure is made an executable file separately, is called by sh by principal function and carries out concrete production test module.After program brought into operation, program can each variable of initialization.The for example number of beginning, finish number, control order that each process is shared or the like.These essential informations are that the form with file is kept under the respective directories, and file content is read when program initialization, is read into behind the end of run.According to the beginning that obtains number with finish number for each number plays a process, each process is called corresponding test module by sh then.
The command format that calls test module is as follows:
./test <interface><ftp_ip><filename> <macaddr> <current?pid>。
This time, each subprocess was carried out program separately, and test process is to communicate by letter with host process by the mode of file with the result.Host process judges that by reading separately corresponding fileinfo thereby the testing procedure of each subprocess and test result make corresponding action.The mode that may transmit has Post, Put etc.Socket programming under the linux system and the curl class libraries under the linux system can be finished this requirement, and this submodule can be write detecting information in the specific file in real time.The following up-downgoing rate verification of the logical packet loss test of checking, ping, each distance that test module mainly contains the software essential information, the download of the ftp under the specific range etc.Relatively independent between each testing procedure, and wherein any one test does not just think that no longer this machine is defective by sundry item.Its basic principle and other two module class like but need to prove that controller will control simultaneously that the distance of all Modem is switched and the state of LED lamp, must can not influence each other between them, otherwise lose the meaning of distance switching and the demonstration of LED lamp.Just need be in order to finish this purpose the order that sends as global variable and be set to critical variable and be the variable that all processes can both be visited, guarantee all when this order being made amendment that other subprocesss can not make amendment to it at every turn.What this invention was adopted is to realize having only a process that this global variable is made amendment with the mode that file is locked at every turn, adopts the mode of the V of system memory shared to realize all processes sharing this order.The concrete use of this order is such: after testing software finishes logical packet loss test of ping and software verification, give an order by PC and to allow controller that the range simulation device is switched to zero kilometer, wait for that then Modem is connected to local side, obtain the up-downgoing rate value judge whether by, PC sends the order that switches to three kilometers and must be worth judgement if test so by zero kilometer.After waiting each distance performance test down to finish, thus carry out under Modem ins succession the situation of outside line that ftp downloads and according to downloaded files size and the speed of downloading used Time Calculation ftp download judge whether by.So will obtain signal and allow the still green light that sends out a warning such as LED according to the test result that obtains Deng host process behind the subprocess EOT.
The realization of instant inserted and instant using type is by circulation and each test process is provided with a marker bit flagarry[n] [1] to write down Modem be in test or EOT.Each subprocess in the process of implementation testing procedure and test result all can be real-time write in the detecting information file, when each subprocess in running, host process also begins these detecting information files of poll, and according to real-time refresh testing step of test file and the necessary data that obtains, when obtaining test result for failure or after successfully finishing, except on state to show test results and bright LED lamp, this time, the flag bit of this machine of EOT also can be changed to 1, it is 0 in the test process, if host process can be to go also to judge that this value of value of this flag bit has been 1 at poll detecting information file, next step just begins to have prepared for next machine test so.This is just in a door being set for the process number of each Modem correspondence, host process in test, can go to inquire about this be close or hold, this closes at ordinary times, what this was exactly out behind EOT at that time, host process just began to do production test for next machine of this port and prepared this time.First following step judges exactly when Modem is changed, because the MAC Address of two machines that will dispatch from the factory is unique, go so when subprocess is tested, can record the MAC Address of the machine of working as Pretesting in the specific file automatically, judgement is that same machine compares according to this address and current MAC Address exactly, if also being changed, identical then machine can not begin new test, when can not get the current address then is to change planes in the device process, then is familiar with machine and is changed when the MAC Address that obtains and current address are inequality.This time is according to the above-mentioned command format that provides, configuration parameter and to generate the new subprocess of new production test just passable.
