It should be noted that the simulation device for engineering field application described in the device embodiment corresponds to the above method embodiment, and its specific implementation process has been described in detail in the method embodiment, and will not be repeated here.

The implementation process of the above-mentioned embodiments will be described in detail below in conjunction with preferred embodiments and accompanying drawings.

Preferred embodiment one

This embodiment provides an automated method for accurately simulating engineering field applications to solve the problems of manual simulation that varies from person to person, huge and cumbersome workload, low efficiency, and high cost. The method includes the following steps:

Step 1, set a time period, and automatically collect and backup the basic situation of the live network (ie, the scale identification information of the live network) and engineering application conditions within the time period.

In the specific implementation process, the automatic collection and backup of the basic information of the existing network may include: in the engineering application process of the system, determine a general and representative time period, the system runs stably during this time period, and automatically collect the scale of the existing network. (that is, the type and quantity of equipment, the average number of alarms in the entire network, and the average performance data of equipment, etc.) and back up the basic information. The content of specific statistics can be selected according to different network applications.

Preferably, the automatic collection of engineering application conditions may include: automatically writing each function and operation time of the system called by operation within the time period into a file.

Step 2, according to the engineering application situation, write the automation script. For example, automation scripts can be written based on the collected engineering application files. Write the automation script once and use it for all subsequent releases, once and for all.

Step 3, build a simulation environment equivalent to the live network, run scripts, and truly simulate engineering applications.

In the specific implementation process, step 3 can be divided into two processes: (1) building a simulation environment equivalent to the engineering application; (2) running an automation script for simulating the engineering application.

Preferably, building a simulation environment equivalent to engineering applications may include: building the same network environment by restoring the backup data of the basic situation of the current network, and then using the equipment simulation platform to simulate all online equipment and generate the same number of alarms and performance data. For example, each equipment supplier has a development equipment simulation platform, which can be used to simulate real equipment and dynamically generate alarm performance data.

Preferably, run the automation script for simulating the engineering application: after setting up a simulation environment equivalent to the project, run the automation script to automatically simulate the functions called during the engineering application process and the calling time interval. During the specific implementation process, the automated script can be run cyclically as needed and run continuously for a long time. In the process of simulating engineering applications, monitor the operating status of the system, identify risks and find problems in advance.

It can be seen that the preferred embodiment of the present invention provides a technical solution for automatically simulating the engineering site application, which accurately simulates the engineering site, realizes automation, overcomes the problems that vary from person to person and the workload is huge and cumbersome during manual simulation, and improves the work efficiency. Moreover, this technical solution can identify serious problems and risks in the system in advance, solve them early to avoid being lost to the project site, reduce the passive situation of fire fighting everywhere, save costs, and improve user satisfaction.

Preferred embodiment two

Fig. 4 is the flow chart of the simulation method of engineering field application according to preferred embodiment 2 of the present invention, and this method may comprise the following steps:

Step S402, automatically counting and backing up the basic situation of the live network. In the process of engineering application of the system, first determine a time period according to the needs, and the operation in this time period is relatively stable and representative, for example, one week or one month. The system automatically counts and backs up the basic information such as the scale of the existing network during this period, that is, the type and quantity of equipment, the average number of alarms on the entire network, and the average performance data of equipment. It should be noted that the content of specific statistics can be selected according to different live network applications. Taking the bearer network as an example, a typical live network is as follows: the network scale (number of devices) is 3,000; the average number of alarms in the entire network is about 600; the number of performance alarms per 15 minutes for each device is about 50.

Step S404, automatically collect engineering application conditions within the time period. That is, each function and operation time of the system called by the user within the time period are automatically written into a file. When the time period is reached, stop writing. For example, the call function file generated by northbound CORBA (Common Object Request Broker Architecture) software is as follows, in which each function has specific parameter input (due to different application scenarios, the input parameters are also different, so this article will not describe in detail here):

2010.6.68:53:09getEmsInfo()//Get network management information

2010.6.68:53:11getAllNodes()//Get all network element information

2010.6.68:53:12getoneNode()//Get the information of a single network element

2010.6.68:53:17getLinks()//Get all topology connections

2010.6.68:53:21getBoards()//Get board information

2010.6.68:53:23getAllCC()//Get all cross connections

2010.6.68:53:31getcurEMSalarms()//Get all current alarms

Step S406, writing an automation script for simulating engineering applications. That is, according to the file generated in step S404, an automation script is written, and this article takes JAVA language as an example for illustration. Usually each software will provide some external interface methods for other software to call. For example, the northbound CORBA interface software provides IDL (standardized interface definition language, Interface Definition Language) for the docking call of the integrated network management of the third manufacturer.

In the specific implementation process, the specific steps of writing the automation script can be as follows: firstly, each function called by the user is realized by the method provided by the system; then, the main function is written, and in the main function, according to step S404 the user The sequence of calling each function is called, and the operation interval between two functions can be replaced by some waiting functions or output functions; finally, an automation script for simulating engineering applications is generated, which is completely consistent with the file generated in step S404.

The getEmsInfa function (other functions called in step S404 are implemented in a similar way) and the main function are used as examples below:

public static void getEmsInfa() throws Exception{

System.out.println("Get Emsinfo starting.......");

EMS_THolder emsinfo = new EMS_THolder();

try{

emsMgr.getEMS(emsinfo);

System.out.println(″ems info is:″+

emsinfo.value.nativeEMSName);

System.out.println(″ems info is:″+

emsinfo.value.userLabel);

}catch(Exception e)

{

System.out.println("Error:"+e);

}

System.out.println("getemsinfo is done.");

}

//The following is the process of completely simulating the application of A project using the main function

public static void main(String[]args)

{

for(int k=1; k<=A; k++)//A is the number of simulation engineering applications

{

      getEmsInfo();//Get network management information

`` Thread.sleep(2000);//sleep 5sec

GetAllNodes();//Get all network element information

Thread. sleep(1000);

GetoneNode();//Get the information of a single network element

Thread. sleep(5000);

GetLinks();//Get all topological connections

Thread. sleep(4000);

GetBoards();//Get board information

Thread. sleep(2000);

GetAllCC();//Get all cross connections

Thread. sleep(8000);

GetcurEMSalarms();//Get all current alarms

System.out.println("Completely simulate an engineering application");

Thread.sleep(60000);//sleep 5sec

}

System.out.println("Simulation Engineering Application End");

}

Among them, the variable A in the main function is the number of simulation engineering applications, which can be set as required.

It should be noted that the automation script for this simulation engineering application only needs to be written once, and it can be used for any version of the system. When the called function changes, only the script of the corresponding function needs to be modified.

Step S408, building a simulated online environment equivalent to the live network. That is, restore the backup data in step S402, build a network environment exactly the same as the current network, and then use the device simulation platform to simulate all devices to make them online, and generate the same number of alarms and performance data as the current network. For example, each equipment supplier has a development equipment simulation platform, which can be used to simulate any kind of equipment of the manufacturer, and can dynamically generate alarm performance data, etc. This method is relatively mature and has been widely used, and the specific details will not be repeated here.

Step S410, running the automation script to actually simulate the engineering application. For example, if the automation script is written in the JAVA language, it is first necessary to ensure that the JDK has been successfully installed on the computer. Secondly, choose a development environment (also called a compilation platform). For example, the JAVA compilation platform can be tools such as jcreater, jbuilder, and eclipse. This article takes the most widely used and free eclipse development platform as an example to elaborate in detail.

Fig. 5 is a schematic diagram of the application of the automation script simulation project according to the second preferred embodiment of the present invention. As shown in Fig. 5, first, the IDL file provided by the northbound CORBA software is compiled on eclipse to generate a specific .class class file And .java source code, these files provide the concrete implementation of all external interface methods.

Secondly, run the automation script of the simulation engineering application written in step S406 on the eclipse, and the method in each function written in the script is covered in the external interface method generated by compiling the IDL. That is to say, the northbound interface CORBA software can recognize every function written in the automation script and respond to every function called in the automation script. The process of running the automation script on eclipse is equivalent to the process of the northbound CORBA interface being operated by the user in the project, achieving the purpose of actually simulating the field application of the project.

It should be noted that the number of simulations can be set in the automation script, and the number of times can be set as needed before running the automation script, so that the purpose of automatically and continuously simulating engineering applications can be achieved.

In summary, in the process of engineering application, the automatic simulation system in the embodiment of the present invention uses some tools to monitor the function of the system in real time and the abnormal situation of the process, the abnormal situation of CPU memory resource occupation and thread blocking, etc., in the laboratory Automatically and accurately simulate the engineering field application, identify major problems and risks of the system in engineering application in advance, detect and solve problems early, avoid problems from flowing to the engineering field, and improve the quality of the system version and user satisfaction. Moreover, this method of writing automated scripts avoids tedious and inaccurate manual operations, and can be reused in multiple versions, improving work efficiency.
