Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

The invention provides a remote check method for the configuration information of the guaranteed substation, constructs the data model of the configuration information of the guaranteed substation, establishes the message communication mechanism between the guaranteed substation and the terminal, and realizes the online verification of the configuration information of the guaranteed substation. Visually display the difference of configuration information, generate a difference report of configuration information, and effectively realize the rapid verification of configuration information of Baoxin substation. An example is given below.

The technical scheme adopted in this embodiment is as follows:

First, according to the characteristics of the configuration information of Baoxin substations, a five-layer data model of substations, devices, CPUs, groups, and entries is designed. The substation layer includes the number of devices and device arrays, and the device layer includes device addresses, CPU numbers, and CPU arrays. , the CPU layer contains the CPU number, group number and group array, the group layer contains the group number, group type, group title, entry quantity and entry array, and the entry layer contains the entry number and entry attributes.

Then, in order to transfer the configuration information data between the terminal and the sub-station, it is necessary to establish a message communication mechanism between the terminal and the sub-station. The message communication mechanism mainly includes message information definition and message processing mechanism. The terminal mainly defines two messages of check start and check stop. Baoxin sub-station mainly defines three messages of device group title, device item attribute and configuration information sending completed.

After the terminal starts the check, it sends a check start message to the network. After receiving the check start message, the Baoxin sub-station sends the device group title and device item attribute message in sequence. The device group title information includes device address, CPU number, group No., group title, device entry attribute message includes fields such as device address, CPU number, group number, entry number, and entry attribute. After receiving the device group title message and the device item attribute message, the terminal compares the data in the established substation configuration data model based on the device address, CPU number, group number, item number and other information in the message. During the checking process, the substation can send a checking stop message to stop the checking process of the current configuration information. After the substation of Baoxin has sent all the configurations of the substation, it will send a message that the configuration information has been sent, prompting the terminal that all the configuration information has been sent.

Then, the terminal establishes a connection with the Baoxin substation, and performs data interaction according to the previously established data model and the designed message communication mechanism; in the process of substation configuration online verification, after the terminal receives the device group title or device item attribute message , analyze the content of the message; and then search in the data model according to the device address, CPU number, group number, item number and other information in the message data, and compare the group title information or item attribute information.

During the online verification of the configuration information of Baoxin substations, if there are differences in the group title information or item attribute information in the configuration information, the terminal can configure the editing tool software in the substation based on information such as device address, CPU number, group number, and item number. Find the display position of the corresponding information on the website, and change the display color of the group title information or item attribute information to indicate that there is a difference in the corresponding configuration information.

Finally, after the entire verification is completed, the terminal generates a configuration information difference report according to the configuration difference information stored during the verification process. The reported items include device address, CPU number, group number, item number, difference attribute, terminal machine value , Baoxin substation value and other fields, if there is a difference in the group title, the entry number field is set to the default value of 0. The naming rule for generating the Baoxin substation difference report document is terminal name_baoxin substation name_check time.

Shown in Fig. 1 is the flowchart of method of the present invention, comprises:

After the terminal starts the check, it sends a check start message to the network;

After the Baoxin substation receives the check start, it parses the message, and sends the device group title and device item attribute messages to the network in sequence;

After receiving the device group title and device item attribute messages, the terminal checks whether the corresponding group title information and attribute information are consistent;

After the terminal receives the check suspension command during the check process, it stops the check, and then sends a check stop message to the network;

After Baoxin sub-station receives the verification suspension message, it stops sending the message;

After the configuration information of the Baoxin substation is sent, it sends a configuration information sending complete message to the network;

After the terminal receives the message that the configuration information has been sent, it terminates the verification;

After the verification is completed, a configuration information difference report document is generated according to the difference information.

Fig. 2 is a 5-layer data model including substations, devices, CPUs, groups, and entries constructed according to the configuration information of the guaranteed substations in this embodiment. Among them, the substation layer includes the number of devices, device 1, device 2, device 3, etc.; the device layer includes device address, CPU quantity, CPU1, CPU2, etc.; the CPU layer includes CPU number, group number, group 1, group 2, etc.; group layer Contains group number, group type, group title, number of entries, entry 1, entry 2, etc.; entry layer contains entry number, attribute 1, attribute 2, attribute 3, etc.

Fig. 3 is a structural diagram of the information definition of the terminal and the sub-station. Information definition includes message type and message body, where message type includes check start, check stop, group title, item attribute and send completed; message body includes group title message body and item attribute message body; group title message body includes device address , CPU number, group number and group title; the entry attribute message body includes device address, group number, CPU number, entry number, attribute 1, attribute 2, etc.

Figure 4 is the display interface of the configuration editing tool during the online calibration process. It can be seen from the figure that the group title with the device address 1, the CPU number 2, and the group number 22 displays an alarm; This title is inconsistent with the group title of the device whose address is 1, CPU number is 2, and group number is 22 running in Baoxin substation. At the same time, the alarm font can also display a specific color, such as red.

Figure 5 is the configuration information difference document generated after the verification. It can be seen from it that in the Baoxin substation, the title of the group whose device address is 1, CPU number is 2, and group number is 22 is "self-inspection information". In the terminal configuration tool, it is "Alarm".
