With the development of computer technology, network communication technology and field bus technology, power dispatching gradually tends to be automatic in the development process of the power dispatching, dispatching between a local side central station and each remote side station is also more and more perfect, in the automatic power dispatching process, in order to ensure communication between the remote side station and the local side central station, power dispatching between the local side central station and the remote side station is usually realized based on a power communication private network and further adopts a proper dispatching number-placing mode, dispatching telephone is used as the most direct means of power dispatching command, high reliability of access operation between the local side central station and the remote side station is required, and in many cases, because the remote side station terminal equipment can only find faults when in use, workers cannot control the power dispatching telephone in time. Therefore, the remote site is comprehensively managed, the running state of the remote site is monitored on line, faults or anomalies of the running of the terminal equipment of the remote site are timely found, and the method is very important for guaranteeing the high reliability of power dispatching realized by applying a dispatching number-placing mode between the central station of the local side and the remote site.

Example 1
In order to solve the problem that in power dispatching, remote sites are difficult to monitor and manage on line due to dispersion, wide range and remote positions, in this embodiment, a method for monitoring the topological on-line state of the remote sites facing the power dispatching is provided, and the flow chart of the method is shown in fig. 1, and as shown in fig. 1, the method comprises the following steps:
s1, primarily dividing a remote site into different initial site groups;
S2, further screening remote sites in the same initial site group to obtain a final site group;
s3, selecting a master remote site from the final site group, taking a remote site outside the master remote site as a slave remote site, connecting the master remote site with a local central station, and connecting the master remote site with the slave remote site in each final site group;
S4, respectively confirming the link conditions between the main remote site and the central site monitoring platform of the local side in each final site group and between the main remote site and the slave remote site in each final site group in a form of scheduling and number-placing response;
S5, each main remote site transmits topology connection data of the remote sites in the final site group to a local side central site monitoring platform, and the local side central site monitoring platform images the topology connection data of each remote site to form a topology connection mapping image;
S6, determining normal operation indexes of each remote site and terminal access equipment thereof, endowing reference standards for each operation index of each remote site and terminal access equipment thereof after imaging, and setting reference threshold errors of each index;
S7, starting running of a central station of the local side, a remote station and terminal access equipment of the remote station, packaging and sending own running logs to a main remote station by a slave remote station of each final station group, packaging and sending own running logs to a central station monitoring platform of the local side by the main remote station together with the running log packages transmitted by each slave remote station;
S8, the central office site monitoring platform receives and analyzes the packed operation logs, compares each operation index in the operation log of each remote site with a reference standard respectively, and judges whether the distances between each operation index and the reference standard respectively do not exceed the reference threshold errors of each index, if so, the operation state of the remote site is normal; otherwise, the abnormal site is operated, and the index with the distance exceeding the reference threshold error of the corresponding index and the corresponding remote site are screened out from the topological connection mapping image to serve as the abnormal site.
Based on the technical process described in steps S1-S8, the disassembly of all remote sites is realized in a group mode, the remote sites of the group are further subjected to refined screening, final site groups are divided, a main remote site is selected to be connected with a local central station in the final site groups, the main remote site is connected with a slave remote site in each final site group, the main remote site is used as a relay, the communication pressure of the local central station directly connected with each remote site is reduced, and the communication reliability is improved; then, the link conditions between the master remote site and the central office site and the link conditions between the master remote site and the slave remote site in each final site group are confirmed, and two layers are divided: firstly, topology connection data of remote sites are transmitted to form a topology connection mapping image, secondly, after standard operation indexes of each remote site and terminal access equipment thereof are defined, the remote sites package and send own operation logs to a local center site monitoring platform, the local center site monitoring platform analyzes and compares the operation logs, indexes with the distance exceeding a corresponding index reference threshold error with a reference standard and corresponding remote sites are screened out from the topology connection mapping image to serve as abnormal sites, and on the premise of overall management of the remote sites, the operation states of the remote sites are monitored on line.
In this embodiment, when the remote sites are disassembled in a group manner, firstly, the remote sites are divided in a group manner from a macroscopic physical distance by taking the physical distance as a threshold standard, so that overall management is convenient for the remote sites which are scattered, wide in range and far away from each other, and specifically, in step S1, the process of primarily dividing the remote sites into different initial site groups is shown in a flowchart shown in fig. 2, and the process is as follows:
s11, setting a distance dividing threshold epsilon, and determining the physical distance between any one of the remote sites and other remote sites;
S12, primarily dividing the remote sites with the physical distances not exceeding epsilon with other remote sites into different initial site groups by taking the distance dividing threshold epsilon as a reference, and obtaining different initial site groups.
And then, on the premise of dividing the macroscopic physical distance angle, further refining the attribution relation of the remote site on the basis of message transmission. If the message receiving interfaces of the remote stations in the same initial station group can receive the messages sent by other remote stations except the message receiving interfaces, the remote stations receiving the messages sent by other remote stations except the message receiving interfaces belong to the same final station group; if the message receiving interfaces of the remote sites in the same initial site group can not receive the messages sent by any other remote sites except the message receiving interfaces, the remote sites are isolated remote sites, and the remote sites are reserved independently;
If the message receiving interfaces of the remote stations in the same initial station group can receive the messages sent by other remote stations except the message receiving interfaces, the remote stations which receive the messages sent by other remote stations except the message receiving interfaces are reserved, and the following processing is performed:
For mutual messages between any one of the reserved remote stations and other remote stations except the remote station, if a message receiving interface can receive messages sent by the other remote stations except the remote station, the remote stations which receive the messages sent by the other remote stations except the remote station belong to the same final station group; if the message receiving interface can not receive the messages sent by other remote sites except the message receiving interface or can only receive the messages sent by partial other remote sites except the message receiving interface, the remote sites are isolated remote sites, and the remote sites are reserved independently;
Finally, the same initial site group may be divided into a number of final site groups and/or a number of isolated remote sites.
In the whole, if a certain remote site can receive messages sent by other remote sites except the remote site during division screening, the communication with other remote sites is not problematic, and the remote sites are classified into the same final site group, so that the subsequent overall management is facilitated; the remote sites which cannot receive the messages sent by the remote sites except the remote sites are isolated, if the remote sites are forced to be classified into the same final site group with other remote sites, the response or transmission of the messages is adversely affected in the follow-up overall management, and the reliability of power dispatching cannot be guaranteed; for the remote sites when the further reserved remote sites are screened in the form of message mutual transmission, the method is equivalent to dividing one final site group again on the premise of dividing the macroscopic physical distance angle, namely the same initial site group is possibly divided into a plurality of final site groups, or divided into a plurality of final site groups and a plurality of isolated remote sites, or completely divided into the isolated remote sites due to improper macroscopic physical distance basis.
After the attribution relation of the remote sites is further refined, from the viewpoint of communication pressure, master and slave relations are screened and divided, if a certain remote site is used as a master site, the remote site must have the performance of being used as a relay, the response speed is high firstly, and for the remote sites which are already divided into a certain final site group, the requirement that messages sent by other remote sites except the remote sites can be received is met, but in order to consider the transmission delay among the sites, the remote site with the highest response speed is selected as the master remote site in the final site group, so that the quality of communication is considered. Therefore, in this embodiment, when a master remote site is selected from a final site group, messages are mutually sent between remote sites in the same final site group, and a message receiving interface of each remote site receives and responds to a message sent by some other remote sites except the message receiving interface, and a remote site with the highest response speed is selected as the master remote site in the final site group.
