Description

Technical Field

[0001] The present invention relates to the technical field of electric power monitoring, and in particular to a household-to-household testing device and a testing method in a station-to-station environment. Background Art

[0002] With the rapid economic development and the growing demand for electricity in society, the scale of the power system is constantly expanding. The HPLC acquisition method currently accounts for more than 90% of the low-voltage acquisition coverage of the State Grid. The HPLC acquisition method is applied differently in different provinces. For example, the plug-and-play method commonly used in Zhejiang Province, when the meter is collected, the reporting concentrator is not fixed, and the current channel with better signals is used for networking. In the subsequent networking process, due to the instability of the network channel, there may be a situation where the reporting channel is changed, that is, the belonging concentrator is changed. This situation is called HPLC serial area. Other provinces use the whitelist method to send the concentrator, that is, the area file is sent to the concentrator as a concentrator file. When based on HPLC application, these two modes need to be compatible.

[0003] Household-meter relationship: refers to the correspondence between each centrally installed meter and each household after the meter boxes for urban and town residents are centrally installed. Cross-household refers to the error in the correspondence between the household and the meter, which will cause the user to pay the wrong fee. In the actual environment, the line behind the meter is generally connected to the user's home by burying the wall. At this time, due to incorrect identification or failure to accept effective means, there is a certain probability of household-meter relationship error. When the household-meter relationship is wrong, the electricity bill used by the user will be measured on the meter of other users, which is easy to cause disputes.

[0004] Existing acceptance methods for household-to-household connections: Traditionally, the method is to confirm by pulling the switch one by one, which brings inconvenience to users' lives, and the test workload is large and easy to miss. The prior art discloses "Patent No. CN201510606891.X A household-meter relationship identification device and method", which realizes household meter identification by identifying the host, identifying the slave, forwarding device, receiving device, and background equipment. This technology applies many types of equipment, the operation is complicated, and the test efficiency is still not high. However, there are many users in the low-voltage area, and one person has a large workload for household testing, is prone to fatigue and errors, and multiple people are required to test together to improve the acceptance efficiency. "Patent No. CN202310044977.2 A household-meter relationship identification method and identification device" discloses a description of the test method for collecting household meters in the electricity meter connection area, but it is necessary to simultaneously mount the management terminal on multiple concentrators, which is cumbersome to mount, has a large workload, and requires high equipment cost support. Summary of the invention

[0005] The purpose of the present invention is to provide a test device and method for household-to-household cross-station environment, which can realize the identification of household-to-household cross-station in low-voltage station area. For the HPLC household-to-household cross-station problem, one terminal can realize the test without the need for multiple station area mounting equipment.

[0006] To achieve the above object, the present invention adopts the following technical solutions: The present invention provides a household-to-household test device in a station-to-station area environment, comprising a master station system, a copy control terminal, and a test terminal: The master station system includes: a master station system recording module, a master station system control module, a master station system analysis module, and a master station system communication module; The copy control terminal includes: a copy control terminal monitoring module, a copy control terminal reading module, and a copy control terminal communication module; The test terminal includes: a test terminal test module and a test terminal communication module; The communication module of the copy control terminal and the communication module of the test terminal are connected to the communication module of the main station system respectively. The copy control terminal is mounted on the power line of the new substation area. The monitoring module of the copy control terminal monitors the power line carrier communication information and reports it to the recording module of the main station system. During the household test, the control module of the main station system issues instructions to control the start and stop of the copy control terminal test module. At the same time, the control module of the main station system issues instructions to the copy control terminal reading module to read the real-time power data of the electric energy meter according to the power line carrier communication information recorded by the recording module of the main station system, and report it to the analysis module of the main station system. The analysis module of the main station system determines whether the corresponding relationship between the household and the meter is correct according to the real-time power data of the electric energy meter when the copy control terminal test module is started and stopped.

[0007] Furthermore, the monitoring module of the copy control terminal monitors the power line carrier communication information, including the number of CCO information and carrier frequency band information on the power line; when the copy control terminal reading module reads the electric energy meter, it automatically switches the CCO information and the carrier frequency band information to read the electric energy meter, ensuring that when the HPLC signal is connected to the substation area, the electric energy meter is read successfully without the need to install equipment in other substation areas.

[0008] Furthermore, when the test module of the test terminal is started, a specified active load occurs, and when it is shut down, the active load is shut down.

[0009] Furthermore, when the electricity meters under the substation are connected to the substation and the data is collected by the concentrators in other substations, the reading module of the meter reading terminal can still read the electricity meters without installing equipment in other substations. The meter reading terminal automatically switches the CCO information of different concentrators to ensure the success rate of meter reading.

[0010] On the other hand, the present invention also provides a method for testing household-to-household communication in a station-to-station environment, comprising the following steps: A. The master station system imports the low-voltage area user file list into the recording module. The file list contains the user address and electric energy meter asset information. The file list is provided by the power supply company. When the user's electricity bill is read and paid, and the corresponding relationship between the household and the meter is checked, this list shall prevail; B. The copy control terminal is mounted on the power line of the test area, and the master station system control module sends instructions to the copy control terminal monitoring module to monitor the communication protocol on the power line, obtain the concentrator information and corresponding meter information on the power line, and report them to the master station system recording module; C. The test terminal is connected to the corresponding user's home according to the user address shown in the user file list of the station area in the main station system recording module; D. The master station system controls the test terminal to generate a specific load, and at the same time controls the reading module of the reading control terminal to disguise as the concentrator information to read the meter, and obtain the corresponding meter power change; E. The main station system analysis module determines whether the household-meter correspondence is consistent according to the meter power change; if it is consistent, it means that the household-meter correspondence is correct; if it is inconsistent, the main station system controls the reading module of the reading control terminal to read other meters in the same meter box and determines whether the power change is consistent. If it is consistent, there is an inconsistency in the household-meter correspondence, and gives the real meter information corresponding to the household address; F. The main station system analysis module determines whether the meter has reverse connection of the input and output lines based on the positive and negative values ​​of the instantaneous active power of the meter. If the instantaneous active power is negative, the input and output lines are reversed.

[0011] After adopting the above technical solution, the beneficial effects of the present invention compared with the prior art are: When checking the inter-household connection, the operator of the present invention only needs to install the meter reading and control terminal in the required test area, and the main station system automatically obtains the electric energy meter belonging to the concentrator file according to the meter reading and control terminal to form a record of the electric energy meter belonging to the concentrator, ensuring that the household-meter correspondence relationship can be checked in the HPLC collection inter-station area scenario. At the same time, a single station area only needs to install one device to complete the household-meter correspondence verification of the entire station area, and there is no need to install equipment on the HPLC inter-station area side, which improves the troubleshooting efficiency, simplifies the test process, and saves manpower and material costs.

[0014] Figure 2 It is a schematic diagram of various modules of a household-to-household testing device in a station-to-station environment in the present invention. DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figure 1-2 As shown, the present invention provides a household-to-household test device in a station-to-station area environment, comprising: a master station system, a copy control terminal, and a test terminal; The master station system includes: a master station system recording module, a master station system control module, a master station system analysis module, and a master station system communication module; The copy control terminal includes: a copy control terminal monitoring module, a copy control terminal reading module, and a copy control terminal communication module; The test terminal includes: a test terminal test module and a test terminal communication module; The communication module of the copy control terminal and the communication module of the test terminal are connected to the communication module of the main station system respectively. The copy control terminal is mounted on the power line of the new substation area. The monitoring module of the copy control terminal monitors the power line carrier communication information and reports it to the recording module of the main station system. During the household test, the control module of the main station system issues instructions to control the start and stop of the copy control terminal test module. At the same time, the control module of the main station system issues instructions to the copy control terminal reading module to read the real-time power data of the electric energy meter according to the power line carrier communication information recorded by the recording module of the main station system, and report it to the analysis module of the main station system. The analysis module of the main station system determines whether the corresponding relationship between the household and the meter is correct according to the real-time power data of the electric energy meter when the copy control terminal test module is started and stopped.

[0017] The monitoring module of the copy control terminal monitors the power line carrier communication information, including the number of CCO information and carrier frequency band information on the power line; when the copy control terminal reads the electric energy meter, the CCO information and carrier frequency band information are automatically switched to read the electric energy meter, ensuring that when the HPLC signal is connected to the substation area, the electric energy meter is read successfully without the need to install equipment in other substation areas.

[0018] When the test module of the test terminal is started, the specified active load occurs, and when it is shut down, the active load is shut down.

[0019] When the electric meters under the substation are connected to the substation and the data is collected by the concentrators in other substations, the reading module of the meter reading terminal can still read the electric meters without installing equipment in other substations. The meter reading terminal automatically switches the CCO information of different concentrators to ensure the success rate of meter reading.

[0020] A method for testing household connections in a cross-station area environment comprises the following steps: A. The master station system imports the low-voltage area user file list into the record module. The file list contains the user address and electric energy meter asset information. The file list is provided by the power supply company. When the user's electricity bill is read and paid, and the corresponding relationship between the household and the meter is checked, this list shall prevail; B. The copy control terminal is mounted on the power line of the test area, and the master station system control module sends instructions to the copy control terminal monitoring module to monitor the communication protocol on the power line, obtain the concentrator information and corresponding meter information on the power line, and report them to the master station system recording module; C. The test terminal is connected to the corresponding user's home according to the user address shown in the user file list of the station area in the main station system recording module; D. The master station system controls the test terminal to generate a specific load, and at the same time controls the reading module of the reading control terminal to disguise as the concentrator information to read the meter, and obtain the corresponding meter power change; E. The main station system analysis module determines whether the household-meter correspondence is consistent according to the meter power change; if it is consistent, it means that the household-meter correspondence is correct; if it is inconsistent, the main station system controls the reading module of the reading control terminal to read other meters in the same meter box and determines whether the power change is consistent. If it is consistent, there is an inconsistency in the household-meter correspondence, and gives the real meter information corresponding to the household address; F. The main station system analysis module determines whether the meter has reverse connection of the input and output lines based on the positive and negative values ​​of the instantaneous active power of the meter. If the instantaneous active power is negative, the input and output lines are reversed.

[0021] In order to more clearly illustrate the above technical solution, the following example is given: When checking the correspondence between the household and the meter, the staff will go to the designated area to install the reading and control terminal of the household-meter correspondence test device. The transformer side of the area is the midpoint of the entire area, where the relative HPLC signal is the best. As a preferred choice, the reading and control terminal of the household-meter correspondence test device is installed here. After the installation is completed, the reading and control terminal automatically goes online, completes communication with the main station system through the communication module, and automatically turns on the monitoring module to monitor the communication data on the power line, including the meter reporting data and the concentrator sending instruction data. For example, the minute freezing data reported by the current meter contains the meter asset number and the corresponding concentrator logical address data. After the reading and control terminal obtains the concentrator logical address corresponding to the electric energy meter, it reports to the main station system recording module to record the meter corresponding to the concentrator list.

[0022] like Figure 1As shown, when a cross-station area occurs, there are 100 electric energy meters in the area, and 4 of them have HPLC cross-station area. The 097-100 meters are collected by the second concentrator 12. At this time, the recording terminal records the logical addresses of the 100 meters corresponding to the concentrator, that is, the 001-096 meters correspond to the logical address of the first concentrator 11, and the 097-100 meters correspond to the logical address of the second concentrator 12. The tester enters the user concentration for testing according to the instructions of the master station system, and inserts the test terminal into the socket of the user's home. At this time, the master station system automatically sends instructions to the test terminal to control the test module to generate specific loads and shut down specific loads. At the same time, the master station system sends instructions to the reading control terminal according to the recorded meter belonging to the concentrator information, and controls the reading control terminal to read the instantaneous active power of the meter according to the corresponding concentrator logical address. After obtaining the instantaneous active power of the meter, it reports to the master station system. The master station system compares the instantaneous active power change value to determine whether the household meter relationship is consistent.

[0023] like Figure 1 After inserting the test terminal in the home of user 101, the master station system sets the test terminal test module to generate a specified load, and reads the corresponding meter 001 in the 101 file to see if the power change is consistent. If it is consistent, the household-meter relationship is correct; if the power change is inconsistent, the household-meter relationship is wrong. At this time, the master station system controls the test terminal test module to generate a specific load again, and controls the reading module of the reading control terminal to read other meters in the meter box. At this time, the instantaneous active power change of meter 002 is consistent with the load change of the test terminal test module, then it is determined that the household-meter relationship between users 101 and 102 is wrong. The correct relationship should be that user 101 corresponds to meter 002, and user 102 corresponds to meter 001. At the same time, according to the positive and negative values ​​of the instantaneous active power of each meter, it is judged whether there is a reverse connection of the input and output lines of the electric energy meter. If the instantaneous active power of meter 001 is negative, it is judged that the meter has a reverse connection of the input and output lines.

[0024] After the installation of meters in a new community is completed, the power supply company generally relies on traditional power off or concentrator-based meter reading methods to verify the household-meter correspondence and the reverse connection of the meter input and output lines. However, there are generally difficulties in the investigation of the cross-station area problem existing in HPLC, and it is often necessary to invest in multiple devices for verification. The present invention provides a household-to-household test device and test method in a cross-station area environment, which does not require multiple stations to install equipment, monitors the meter cross-station area situation in real time, simplifies the household-meter correspondence investigation process, improves the investigation efficiency, and saves manpower and material resources.

[0025] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
