All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the examples of the present application, with regard to the explanation of the concentrator and the electric energy meter described:
the concentrator is a device which collects data of each electric energy meter, processes and stores the data, and can exchange data with a master station or a handheld device.
The electric energy meter is used for metering electric energy of low-voltage users and can generate various electric energy data. The electric energy meter for charging is also installed at a low-voltage user, and is different from various non-charging electric energy meters installed under a low-voltage platform area, and is also called as a user meter; the electric energy meters which are installed at low-voltage outgoing lines, branch lines, meter box inlets and the like in a low-voltage distribution room and can measure and communicate, but do not participate in charging are respectively called as line terminals, branch terminals, meter box terminals and the like which are collectively called as non-user meters.
The carrier module is a single-phase power line communication modem and transmits data signals by using a power grid.
In daily operation, the change of information of measurement points of the electric energy meter (such as expansion and capacity increase, meter removal and sales, temporary removal, meter movement and the like) and the load cutting and connecting and other services can cause the change of the electric energy meter files of users in the centralized meter reading system.
At present, the change of the information of a measuring point of an electric energy meter relates to the adoption of electric energy meter archives of manual change users in the background technology, and in the research process of how to timely, accurately and conveniently obtain and process archive change information and reduce the workload of workers, the problem that the concentrator and the electric energy meter module integrate the sending and receiving functions of zone identification signals in the zones of the electric energy meter provided with the concentrator of the carrier module and the carrier module through the zone identification technology of broadband carrier waves is found, the concentrator periodically initiates a zone identification process, identifies the electric energy meter in the zone, finds the change condition and reports the change condition to a master station through an alarm event. However, the change alarm of the technology is only to report the newly added unknown electric meters in the local area. The method can not effectively feed back and process 2 associated operations of newly increasing and removing the power station area caused by the removal and the load cutting of the electric energy meter. The existing problem is that the concentrator only compares the internal file of the concentrator, and in reality, another concentrator (the concentrator can belong to the local area or a non-local area) may exist in the file, and the data obtained by changing the information of the measuring point of the electric energy meter is inaccurate, so that the actual attribution of the electric energy meter cannot be accurately judged, and the data accuracy of meter reading of the meter reading system is influenced.
Therefore, the embodiment of the application provides a processing method and device for collecting and copying system equipment change information and computer equipment, based on the function of data transmission of a carrier module, the information of the electric energy meter about the measurement point of the newly added or removed electric energy meter is transmitted to a concentrator, and then a master station informs workers, so that the electric energy meter file accuracy of users is improved; and the master station sends an instruction to the concentrator to execute filing or remove files according to the address of the inquiry concentrator for the information of the measuring points of the newly added or removed electric energy meter, manual filing is not needed, the workload of workers is reduced, and the technical problems that the existing centralized copying system needs the workers to update, process and check the information under the condition of changing the electric energy meter files, the workload is large, and the accuracy and the timeliness cannot be guaranteed are solved.
The first embodiment is as follows:
fig. 1 is a flowchart illustrating steps of a method for processing change information of a centralized meter reading system according to an embodiment of the present invention. In the embodiments of the present application, the measurement point information after the change of the electric energy meter information is exemplified as the change of the electric energy meter archive confidence. The electric energy meter and the concentrator all comprise carrier modules.
As shown in fig. 1, an embodiment of the present invention provides a method for processing device change information of a centralized meter reading system, which is applied to the centralized meter reading system, and includes the following steps:
s1, a concentrator of a centralized meter reading system identifies a topological relation of a low-voltage power grid, the concentrator generates abstract information of the topological relation, the abstract information is changed compared with the abstract information of the concentrator at the last time, and a changed electric energy meter is inquired according to the topological relation of the low-voltage power grid of the concentrator and the changed abstract information;
s2, the concentrator acquires the changed measuring point information of the electric energy meter, and generates reported measuring point change warning information and a second address corresponding to the measuring point change warning information in the concentrator;
s3, the concentrator inquires a first address of a last concentrator meter reading of the electric energy meter, and a second address of the concentrator is compared with the first address of the last concentrator;
s4, if the first address is inconsistent with the second address, the concentrator reports the change warning information of the measuring point to a master station, meanwhile, the concentrator inquires the master station of the previous concentrator to acquire the measuring point information of the previous concentrator, and reports the measuring point information to the master station;
and S5, if the user of the measuring point information is a non-user meter, the master station issues an electric energy meter file adding operation instruction to the concentrator and an electric energy meter file deleting operation instruction to the previous concentrator according to the measuring point change alarm information and the measuring point information.
In an embodiment of the invention, the concentrator identifies the low voltage power grid topology periodically (e.g. one day), and the concentrator stores thereon summary information of the low voltage power grid topology and the relationship of the low voltage power grid topology. In the summary information, as long as a certain device of the structure of the low-voltage power grid topology changes, the summary information in the concentrator also changes. And comparing the abstract of the concentrator with the abstract information generated by identifying the low-voltage power grid topology by the concentrator last time, and if the abstract of the concentrator is not consistent with the abstract information, indicating that the low-voltage power grid topology is changed or has other abnormalities. For example: fig. 2 is a low-voltage power grid topological diagram, and fig. 3 is a low-voltage power grid topological diagram after information change; as shown in fig. 2 and 3, numerals 1, 2, 3, 4, 5, 6, and 7 are power devices in a low voltage power grid, respectively, if 4, 5, 6, and 7 are power meters, the power meters 5 and 6 in the low voltage power grid topology are shifted in position, and thus the summary information generated by the concentrator identifying the low voltage power grid topology in fig. 3 is different from the summary information generated by the concentrator identifying the low voltage power grid topology in fig. 2. And then the concentrator queries the changed electric energy meter in the low-voltage power grid topology according to the low-voltage power grid topology relation and the changed abstract information.
It should be noted that the low-voltage power grid topology refers to a grid structure of the low-voltage power grid, and the electric energy meter is also located on the grid structure of the low-voltage power grid topology. The summary information is calculated by a CRC32 method, a CRC utility library is in the fields of data storage and data communication, and in order to ensure the correctness of data, an error detection means has to be adopted, and CRC is called cyclic redundancy check.
In an embodiment of the present invention, if the measurement point information of the electric energy meter of the low-voltage power grid topology changes, that is, the measurement point information of the electric energy meter changes, the carrier module in the concentrator receives the measurement point information sent by the carrier module in the electric energy meter, and generates, in the concentrator, the measurement point change alarm information corresponding to the measurement point information and an address corresponding to the measurement point change alarm information, where the address is denoted as a second address. And inquiring the address of the electric energy meter which is read by the concentrator after the information is changed from the concentrator by the master station according to the change alarm information of the measuring point, wherein the address is marked as a first address. Comparing the second address of the concentrator with the first address of the previous concentrator, there are three cases:
the first address is consistent with the second address, that is, the first address is the same as the second address, the concentrator does not report the measurement point change alarm information to the master station, that is, the concentrator does not report the electric energy meter with changed information to the master station, which indicates that an electric energy meter file of the electric energy meter with changed information already exists, and the measurement point information of the electric energy meter with changed information is collected and stored by the previous concentrator. It should be noted that the energy meter is an old meter, which may be moved within a district and/or within the concentrator, i.e. the energy meter of one branch of the low voltage network topology is moved to another branch. A transformer area refers to the power supply range or area of a (single) transformer.
And secondly, the first address and the second address are both empty, that is, neither the first address nor the second address exists, the concentrator does not report the measurement point change alarm information to the master station, and the concentrator does not report the electric energy meter with changed information to the master station, which indicates that the electric energy meter with changed information is a new meter. It should be noted that the electric energy meter after the change of the description information is not collected by any concentrator before.
And thirdly, the first address is inconsistent with the second address, namely the first address is different from the second address, the concentrator reports the change alarm information of the measuring point to the master station, namely the concentrator reports the electric energy meter with changed information to the master station, meanwhile, the concentrator inquires the master station of the last concentrator to acquire the information of the measuring point of the last concentrator and reports the information of the measuring point to the master station, which indicates that the last concentrator collects measuring point information data of the electric energy meter with changed information. The situation that the electric energy meter archive of the electric energy meter after information change does not exist is explained, the measuring point information of the electric energy meter after information change is not collected by the previous concentrator, and the electric energy meter data collected by the previous concentrator does not contain the electric energy meter after information change, namely the electric energy meter archive in the previous concentrator is inconsistent with the field electric energy meter equipment, so that the data collected by the centralized meter reading system is inaccurate. And the master station establishes the electric energy meter file according to whether the electric energy meter after the information change is a user meter.
It should be noted that, if the first address is not consistent with the second address, the low-voltage power grid topology is changed, for example: the transformer power supply is replaced.
In the embodiment of the invention, the electric energy meter after information change has two situations, one is that the electric energy meter after information change is a non-user meter, the master station issues an electric energy meter file operation instruction of the electric energy meter after information change to the concentrator, the master station deletes the electric energy meter file operation instruction of the previous concentrator from the previous concentrator, and the electric energy meter measuring point information after information change is executed in the concentrator and the electric energy meter file obtained by the previous concentrator is deleted, so that the electric energy meter file of the user in the concentrator can be automatically changed. And secondly, the electric energy meter after the information change is a user meter, the master station sends out a warning to inform a master station worker, and the worker operates the information of the measuring point.
The processing method for the equipment change information of the centralized meter reading system provided by the invention inquires the changed electric energy meter and transmits the changed electric energy meter information to the concentrator through the topological relation of the low-voltage power grid of the concentrator and the changed abstract information; the concentrator receives the electric energy meter information and generates reported measuring point change warning information and a second address corresponding to the reported measuring point change warning information; based on the reported change alarm information of the measuring point, the master station inquires the concentrator about a first address of the electric energy meter read by the last concentrator, and compares a second address of the concentrator with the first address of the last concentrator; if the first address is inconsistent with the second address, the concentrator reports measurement point change alarm information to the master station, meanwhile, the concentrator inquires the master station of the previous concentrator to acquire the measurement point information of the previous concentrator and reports the measurement point information to the master station, and if a user of the measurement point information is an unused meter, the master station sends a file operation instruction for adding the measurement point information to the concentrator and sends a file operation instruction for deleting the stored electric energy meter to the previous concentrator according to the reported measurement point change alarm information and the measurement point information. According to the processing method for the change information of the centralized meter reading system equipment, the main station sends an instruction to the concentrator to execute file creation or remove files according to the address of the inquiry concentrator for the measurement point information of the newly added or removed electric energy meter, manual file creation is not needed, and the workload of workers is reduced; and the automatic processing mode is directly adopted by the master station for the non-user meters, and the meter change information is timely reminded for the user meters, so that the information processing efficiency of the electric energy meter equipment after the change is improved. The technical problems that under the condition that the electric energy meter files are changed, a worker needs to complete information updating processing and checking, the workload is large, and the accuracy and the timeliness cannot be guaranteed in the conventional centralized meter reading system are solved.
In one embodiment of the invention, the measurement point information of the electric energy meter is transmitted to the carrier module of the concentrator through the carrier module of the electric energy meter.
Example two:
fig. 4 is a block diagram of a processing device for collecting change information of system devices according to an embodiment of the present invention.
As shown in fig. 4, an embodiment of the present invention provides a device for processing device change information of a centralized meter reading system, which is applied to the centralized meter reading system, and includes:
the information transmission unit 10 is configured to identify a topological relation of a low-voltage power grid by using a concentrator of a centralized meter reading system, generate abstract information of the topological relation by using the concentrator, change the abstract information compared with the abstract information of the concentrator at the last time, and query a changed electric energy meter according to the topological relation of the low-voltage power grid of the concentrator and the changed abstract information;

and a second control unit 50, configured to control the master station to issue an electric energy meter file operation instruction to the concentrator and to issue an electric energy meter file deletion operation instruction to the previous concentrator according to the measurement point information, the measurement point change alarm information, and the measurement point information if the user of the measurement point information is a non-user meter.
In this embodiment of the present invention, the second control unit 50 is further configured to control the concentrator not to report the measurement point change alarm information to the master station according to a comparison result between the first address and the second address, where the comparison result indicates that the first address is consistent with the second address.
In the embodiment of the present invention, in the address query unit 30, if the queried first address and second address are both empty, the second control unit 50 is further configured to control the concentrator not to report the measurement point change alarm information to the master station.
In an embodiment of the present invention, the first control unit 40 is further configured to control the master station to send an alert to notify a master station staff member according to the fact that the user of the measurement point information is a user table, and the staff member operates the measurement point information.
It should be noted that, in the information transmission unit 10, the electric energy meter is an electric energy meter with changed information, the measurement point information of the electric energy meter changes, and the carrier module in the concentrator receives the measurement point information sent by the carrier module in the electric energy meter. In the reported information obtaining unit 20, the measurement point change warning information corresponding to the registration node and an address corresponding to the measurement point change warning information are generated in the concentrator, and the address is marked as a second address. In the address query unit 30, according to the measurement point change alarm information, the master station queries the concentrator for an address of the concentrator meter reading of the electric energy meter after the information change, and the address is recorded as a first address. Comparing the second address of the concentrator with the first address of the previous concentrator, there are three cases:
the first address is the same as the second address, that is, the first address is the same as the second address, the first control unit 40 controls the concentrator not to report the measurement point change alarm information to the master station, that is, the concentrator does not report the electric energy meter after information change to the master station, which indicates that an electric energy meter file of the electric energy meter after information change already exists, and the measurement point information of the electric energy meter after information change is collected and stored by the previous concentrator. It should be noted that the energy meter is an old meter, which may be moved within a district and/or within the concentrator, i.e. the energy meter of one branch of the low voltage network topology is moved to another branch. A transformer area refers to the power supply range or area of a (single) transformer.
The second is that the first address and the second address are both null, that is, neither the first address nor the second address exists, the first control unit 40 controls the concentrator not to report the measurement point change alarm information to the master station, and also the concentrator does not report the electric energy meter after information change to the master station, which indicates that the electric energy meter after information change is a new meter. It should be noted that the electric energy meter after the change of the description information is not collected by any concentrator before.
Thirdly, the first address is not consistent with the second address, that is, the first address is different from the second address, the first control unit 40 controls the concentrator to report the measurement point change alarm information to the master station, that is, the concentrator reports the electric energy meter with changed information to the master station, and meanwhile, the concentrator queries the master station to acquire the measurement point information of the previous concentrator and reports the measurement point information to the master station, which indicates that the previous concentrator collects measurement point information data of the electric energy meter with changed information. The situation that the electric energy meter archive of the electric energy meter after information change does not exist is explained, the measuring point information of the electric energy meter after information change is not collected by the previous concentrator, and the electric energy meter data collected by the previous concentrator does not contain the electric energy meter after information change, namely the electric energy meter archive in the previous concentrator is inconsistent with the field electric energy meter equipment, so that the data collected by the centralized meter reading system is inaccurate. And the master station establishes the electric energy meter file according to whether the electric energy meter after the information change is a user meter.
It should be noted that, if the first address is not consistent with the second address, the low-voltage power grid topology is changed, for example: the transformer power supply is replaced.
In the embodiment of the present invention, in the second control unit 50, the electric energy meter after information change has two situations, one is that the electric energy meter after information change is a non-user meter, the second control unit 50 controls the master station to issue an electric energy meter file operation instruction of the electric energy meter after information change to the concentrator, controls the master station to delete an electric energy meter file operation instruction of the previous concentrator from the previous concentrator, and executes the electric energy meter measurement point information after information change in the concentrator and deletes the electric energy meter file acquired by the previous concentrator, thereby implementing automatic change of the electric energy meter file of the user in the concentrator. And secondly, the electric energy meter after the information change is a user meter, the master station sends out a warning to inform a master station worker, and the worker operates the information of the measuring point.
According to the processing device for the change information of the centralized meter reading system equipment, provided by the invention, the second control unit is adopted to realize the measurement point information of the newly added or removed electric energy meter, and the second control unit controls the master station to send an instruction to the concentrator to execute the filing or remove the file according to the address of the concentrator inquired by the address inquiry unit, so that the manual filing is not needed, and the workload of workers is reduced; and the master station is controlled by the second control unit to directly adopt an automatic processing mode for the non-user meters, so that the user meters are timely reminded of meter change information, and the information processing efficiency of the electric energy meter equipment after change is improved. The technical problems that under the condition that the electric energy meter files are changed, a worker needs to complete information updating processing and checking, the workload is large, and the accuracy and the timeliness cannot be guaranteed in the conventional centralized meter reading system are solved.
