Fig. 1 is a schematic diagram of an application scenario of a method for identifying a region according to an embodiment of the present invention. As shown in fig. 1, the method for identifying a station area in the embodiment of the present invention at least involves two station areas, wherein stations actually included in the station area a are STA1-11 to STA1-24, stations actually included in the station area B are STA2-11 to STA2-24, however, in the history networking or the file relationship recorded in each station area, the stations STA1-24 are wrongly assigned to the station area B, and the stations STA2-21 are wrongly assigned to the station area a, which causes abnormal user-change relationship, so that the file of the station area is disordered.
In the process of identifying the station area, the CCO1 of the station area a and the CCO2 of the station area B can respectively initiate networking to form communication networks corresponding to the station area a and the station area B, further, the CCO1 and the CCO2 respectively broadcast station area characteristic acquisition commands according to respective periods, acquire and broadcast respective CCO zero crossing data according to respective station area characteristic acquisition commands, each station acquires respective STA zero crossing data according to the received station area characteristic acquisition commands, and generates zero crossing point deviation corresponding to the station area characteristic acquisition commands according to the corresponding CCO zero crossing data and the STA zero crossing point data, wherein the received plurality of station area characteristic acquisition commands of one station correspond to a plurality of groups of zero crossing point deviation to form a zero crossing point deviation set of the station, and each station judges a station area identification result according to the respective zero crossing point deviation set and reports the station area identification result to the CCO corresponding to the respective communication network. And the CCO1 and the CCO2 respectively judge whether the station area identification results of all stations in the communication network are received or not, if so, the respective station area identification results are reported to the master station through the concentrator of the respective station area, if not, the station area characteristic acquisition command is continuously sent according to the respective period, and the acquisition and identification work of the station area characteristics of the next period is continuously started. Optionally, after receiving the zone identification results of CCO1 and CCO2, the master station issues a zone identification stop command, and after receiving the zone identification stop command, CCO1 and CCO2 stop the zone identification task.
In an optional implementation manner, in the networking process, the whitelists corresponding to the respective whitelists can be generated through the archive communication domains recorded by the station area A and the station area B, and the CCO1 and the CCO2 are used for networking the stations according to the whitelists. Alternatively, networking may be performed according to other manners, for example, the sites of each station area may be configured according to the received networking signal to form a communication network corresponding to each station area, which is not limited in the embodiment of the present invention.
In the embodiment of the invention, the above-mentioned platform region characteristic acquisition command includes acquisition information, which is used for specifying acquisition time and acquisition quantity, so that the CCO sending the platform region characteristic acquisition command and the STA receiving the platform region characteristic acquisition command can acquire respective zero crossing point data in the same time period according to the acquisition time.

The area identification process of the embodiment of the invention relates to two adjacent areas, and in the actual application scene, the abnormal areas are not limited to the two areas, and the area identification method of the embodiment of the invention can be applied to a plurality of areas causing the confusion of the area relation. Optionally, according to different actual requirements, the master station may use the to-be-identified area as a target area, where the target area may be one or multiple, and the master station stops the area identification after receiving the area identification result reported by the target area, for example, uses the area a as the target area, and issues an area identification stop command to stop the area identification of the area a and the area B after receiving the area identification result of the area a. The area identification may be stopped after receiving the area identification results of the plurality of areas causing the confusion of the area relationship, for example, the area a and the area B may be used as target areas, and after receiving the area identification results of the area a and the area B, an area identification stop command may be issued to stop the area identification of the area a and the area B.
Fig. 2 is a flowchart of a method for identifying a station area according to an embodiment of the present invention, and as shown in fig. 2, the method for identifying a station area according to an embodiment of the present invention includes the following steps:
in step S210, the CCO of the target zone and the associated zone periodically broadcasts a zone feature acquisition command based on the corresponding periodicity, where the zone feature acquisition command includes acquisition information.
In the embodiment of the invention, the target area is the area to be subjected to the area identification service currently, the associated area is one or more areas which possibly influence the area identification result and are within a preset range from the target area, roles of the target area and the associated area can be mutually converted according to different actual requirements, and if the area identification result of the adjacent areas is to be determined, the adjacent areas can be regarded as targets to determine the corresponding area identification result.
In an alternative implementation, before performing the area identification, the method further includes: the CCO of the target station area networks the stations in the corresponding communication domain to form a communication network corresponding to the target station area. Optionally, the sites of the target area and the associated area may be networked to form communication networks corresponding to the different areas.
Optionally, when the CCO of the target area and the associated area performs networking, networking is performed according to the whitelist issued by each concentrator, so that the CCO of each area can quickly and accurately complete networking of each station into the network.
After the completion of the CCO confirmation networking of each zone, the zone feature collection command starts to be sent, and because there may be a difference in networking time of CCO of different zones, the time for the CCO of each zone to send the zone feature collection command may be different, but is generally within a predetermined duration, that is, after the zone identification task starts for a period of time, each station may determine, based on all the zone feature collection commands received by the station, CCO of all the zones that can be detected by itself in the zone identification task.
However, the collection time in the region feature collection command sent by the CCO of each region may be greatly different due to different equipment manufacturers or region settings, so that certain sites can only receive the region feature information of the CCO of part of the regions within a certain period of time and cannot give a correct region identification result.
Step S220, the CCOs of the target station area and the associated station area collect and broadcast the CCO zero crossing data of the target station area and the associated station area according to the corresponding collected information.
After CCOs of the target station area and the associated station areas send station area characteristic acquisition commands, acquiring power frequency zero crossing data of the target station area and the associated station areas according to acquired information in the respective sent station area characteristic acquisition commands to form CCO zero crossing data of each station area, and broadcasting the acquired CCO zero crossing data to each station.
Step S230, the CCO of the target station area receives the station area identification result sent by the station in the corresponding communication network, and updates the station area identification result set.
The station area identification method in the embodiment of the invention is a distributed identification method, namely, each station determines own station area, each station can determine zero crossing point deviation based on own zero crossing point data and the received zero crossing point data of all station areas, the corresponding station area with the smallest zero crossing point deviation value is determined as the own station area, and the own station area identification result is reported to the CCO of the communication network corresponding to the station or to the CCO of each station area which can be detected by the station.
The CCO of the target station receives the station identification results of each station to form a station identification result set, and optionally, the target station may receive the station identification results of the stations of the present communication network, or may receive the station identification results of the stations of other communication networks.
Step S240, the CCO of the target station determines a station identification result of the target station in response to the station identification result set including station identification results of all stations in the corresponding communication network.
Taking the application scenario shown in fig. 1 as an example, when the area a is taken as the target area, if the area identification result set of the CCO1 includes the area identification results of all the stations in the corresponding communication network, the area identification result of the area a may be determined based on the area identification result, and it is determined that the stations STA2-21 in the corresponding communication network do not belong to the own area and belong to the area B.
Further, the station area B may determine the station area identification result of the station area B based on the same method, and determine that the stations STA1-24 in the corresponding communication network do not belong to the own station area and belong to the station area a.
Optionally, the method for identifying a station area according to the embodiment of the present invention further includes: and the CCO of the target station area and the associated station area receives a station area identification stop command, and stops station area identification operation. In an alternative implementation manner, after the target area and the associated area determine the corresponding area identification result, reporting the area identification result to the corresponding concentrator and then to the master station, after the master station receives the area identification results of the target area and the associated area, determining that the stations of the corresponding area have the area identification result, issuing an area identification stop command, and stopping area identification after CCO of each station receives the area identification stop command.
The CCO of each station area of the embodiment of the invention periodically sends the station area feature acquisition command, so that each station receives the CCO zero crossing data of all stations which can be received by the station in a certain period of time under the multi-manufacturer multi-environment application scene, and gives a more accurate identification result based on the data, and the accuracy of the station area identification result is improved under the condition of compatibility, taking the application scene shown in fig. 1 as an example: if the acquisition time corresponding to the station characteristic acquisition command sent by the CCO1 is t1-t2, and the acquisition time corresponding to the station characteristic acquisition command sent by the CCO2 is t3-t4, where t1-t2 is before t3-t4 and the time interval between them is longer, the STA2-21 may give an erroneous recognition result after receiving the CCO zero-crossing data sent by the CCO1 and not receiving the CCO zero-crossing data from the CCO2 for a long time, or the STA2-21 receives the CCO zero-crossing data from the CCO1 and the CCO2, but the recognition result is inaccurate due to the large difference in the acquisition time. In the embodiment of the invention, after the CCO sends the region characteristic acquisition command and completes one round of region identification action, if the region identification stop command is not received, the region identification action of the next round is continued to be started, so that some stations can acquire CCO zero-crossing data of a plurality of regions which can be detected by the stations in the same time period, and a more accurate identification result is given.
Fig. 3 is a flowchart of a method for identifying a station area of an embodiment of the present invention, where a process of receiving a station area feature collection command by a station is taken as an example to describe an identifying process of the method for identifying a station area of the embodiment of the present invention, and as shown in fig. 3, the method for identifying a station area of the embodiment of the present invention includes the following steps:
step S310, receiving a district character collecting command broadcasted by the CCO, wherein the district character collecting command comprises collecting information.
Optionally, the collected information includes a combination of one or more of: the CCO identification, the CCO reference time, the acquisition starting time, the acquisition time and the acquisition period in the acquisition time can be acquired according to the actual situation and the acquisition information in the characteristic acquisition command of each station when each station and the CCO acquire zero crossing point data.
And step 320, acquiring the STA zero-crossing data of the current station according to the acquired information.
In the embodiment of the invention, some stations can receive the station area characteristic acquisition command sent by the CCO in the communication network where the stations are located and also can receive the station area characteristic acquisition command sent by the CCO of other stations, and when each station processes the received station area characteristic acquisition command, the stations acquire the STA zero crossing point data according to specific application scenes and acquisition information. For example, in some cases, when the station collects STA zero-crossing data of itself, the station may first check and adjust its own clock based on the collecting CCO reference time, and then collect the power frequency zero-crossing data of itself according to the collecting time in the collecting information, so as to obtain the corresponding STA zero-crossing data.
Optionally, if the acquisition times corresponding to the plurality of station region feature acquisition commands received by the station overlap, the station may acquire STA zero crossing data of the station itself in the same period of time, and then process the acquired STA zero crossing data according to the acquisition information in the plurality of station region feature acquisition commands, so as to form STA zero crossing data corresponding to each of the plurality of station region feature acquisition commands.
Step S330, receiving CCO zero crossing data corresponding to the platform region characteristic acquisition command.
In the embodiment of the invention, the CCO zero crossing data and the STA zero crossing data of the same station characteristic acquisition command correspond to the same sampling time, the sampling period and the sampling number, namely the CCO zero crossing data and the STA zero crossing data corresponding to the same station characteristic acquisition command are the same, the zero crossing time may have deviation, the deviation of the zero crossing points of the CCO and the station in the same station is smaller, the deviation of the zero crossing points of the CCO and the station in different stations is relatively larger, and if the station can receive the CCO zero crossing data of different stations, the station can determine the station based on the deviation value of the zero crossing points of the station relative to the different stations.
And step 340, determining zero crossing point deviation corresponding to the station region characteristic acquisition command according to the CCO zero crossing point data and the STA zero crossing point data.
Fig. 4 is a schematic diagram of a calculation flow of a zero crossing point deviation corresponding to a station characteristic acquisition command according to an embodiment of the present invention, in an alternative implementation manner, the acquisition information includes an acquisition time, where the acquisition time includes one or more acquisition periods, and as shown in fig. 4, the determining, by the current station, the zero crossing point deviation corresponding to the station characteristic acquisition command according to the CCO zero crossing point data and the STA zero crossing point data includes:
step S410, respectively calculating time deviations of the CCO zero-crossing points in each acquisition period and the multiple zero-crossing points of the STA zero-crossing points in the corresponding order.
Optionally, if the acquisition time includes one acquisition period, calculating time deviations of the CCO zero-crossing points in the acquisition period and the multiple zero-crossing points of the STA zero-crossing points in the corresponding order, and if the acquisition time includes multiple acquisition periods, calculating time deviations of the CCO zero-crossing points in each acquisition period and the multiple zero-crossing points of the STA zero-crossing points in the corresponding order.
Step S420, respectively calculating the average value of the time deviations of the zero crossings in each acquisition period, and obtaining the time parameters corresponding to each acquisition period.
Optionally, if the acquisition time includes one acquisition period, calculating the average value of the time deviations of the zero crossings in the acquisition period, acquiring the time parameter corresponding to the period, determining the time parameter corresponding to the period as the zero crossing deviation of the current platform region characteristic acquisition command, and if the acquisition time includes a plurality of acquisition periods, calculating the average value of the time deviations of the zero crossings in each acquisition period, and taking the average value as the time parameter corresponding to each period.
Step S430, determining the average value of the time parameters with the largest preset number of values in the acquisition time as the zero crossing point deviation of the corresponding platform region characteristic acquisition command.
Optionally, the predetermined number is preconfigured according to a number of cycles included in the acquisition time, and the predetermined number is smaller than or equal to the number of cycles included in the acquisition time.
For example, if the collection time specified by one station area feature collection command includes 5 periods, namely T1-T5, and each period includes 10 zero crossings, the preset number of calculated station area feature collection command zero crossing deviations is 3. Then first calculate 10 CCO zero crossings t in each cycle CCOi And corresponding sequence of STA zero-crossing points t STAi Time offset Δti= |t of (a) CCOi -t STAi And calculating the average value delta tmean of the time deviations of 10 zero crossings in each period, and if delta tmean corresponding to 5 periods of T1-T5 is 0.05, 0.06, 0.07, 0.08 and 0.06 respectively, taking the average value delta tmean corresponding to T2, T3 and T4 as the zero crossing point deviation of the station characteristic acquisition command, and obtaining the zero crossing point deviation of the station characteristic acquisition command to be 0.07 millisecond.
And step S350, determining a station identification result of the current station according to the zero crossing point deviation set in response to the zero crossing point deviation set meeting a preset condition.

For example, if the current station receives the station characteristic acquisition commands sent by the station a, the station B and the station C within a period of time after the station identification task is started, determining that the relevant station of the current station is the station a, the station B and the station C, where the predetermined condition may be zero crossing point deviation of the station characteristic acquisition commands of at least the 3 stations in the zero crossing point deviation set corresponding to the current station.
In an optional implementation manner, the determining, by the current station, the zone identification result of the current station according to the zero-crossing deviation set in response to the zero-crossing deviation set meeting a predetermined condition includes: responding to zero crossing point deviation corresponding to a platform region characteristic acquisition command of CCO only comprising a target platform region in a zero crossing point deviation set, and determining one platform region corresponding to the zero crossing point deviation set as a self affiliated platform region; and responding to the zero crossing point deviation corresponding to the region characteristic acquisition command of the CCO comprising a plurality of regions in the zero crossing point deviation set, and determining the region to which the current station belongs based on the plurality of regions.
In an optional implementation manner, the determining, based on the plurality of zones, the zone to which the current station belongs in response to the zero-crossing point deviation corresponding to the zone feature acquisition command of the CCO including the plurality of zones in the zero-crossing point deviation set includes: taking zero crossing point deviation corresponding to a district characteristic acquisition command transmitted by CCOs of the districts for the last time as a comparison sample, and determining a district corresponding to the district characteristic acquisition command corresponding to the smallest zero crossing point deviation in the comparison sample as a district to which the district belongs. According to the embodiment of the invention, the zero crossing point deviation corresponding to the region characteristic acquisition command transmitted by the CCO of each region for the last time is compared, so that the zero crossing point deviation compared by each region is in a similar time period, and the accuracy of the region identification result is enhanced.

In an alternative implementation manner, after determining the own station area identification result, the station may automatically send the own station area identification result to the CCO of the located communication network, or alternatively, may send the own station area identification result to the CCO of the relevant station area.
In another alternative implementation manner, after the CCO broadcasts the CCO zero crossing data of the CCO, a station identification result query signal may be sent to the station in the corresponding communication network, and after the station receives the station identification result query signal, the station sends the determined own station identification result to the corresponding CCO.
In the embodiment of the invention, the station receives the station characteristic acquisition command periodically sent by the CCO of each station, determines own relevant station based on the CCO corresponding to the received station characteristic acquisition command, further determines the zero crossing point deviation corresponding to each station characteristic acquisition command, and determines own station identification result after determining the zero crossing point deviation of the station characteristic acquisition command of all relevant stations.
