Description

Technical Field

[0001] The present invention relates to the technical field of household meter management, and in particular to a preinstalled household meter acceptance device. Background Art

[0002] With the acceleration of urbanization, the number of newly built residential areas is increasing. In order to ensure the power supply quality and power safety of newly built residential areas, it is necessary to check the correspondence between "meter box and household meter location", "household meter location and house number", and "household meter and transformer" before the completion and acceptance of the residential power supply project.

[0003] At present, there is a new residential area acceptance control device and solution (Chinese invention patent CN202011193835.5), which uses the existing data collection system of the power supply company to test and accept the relationship between the household meter and the household transformer in the new residential area, and effectively controls the acceptance process. However, this method requires testing and accepting each user one by one after the residential area is powered on, which is a large workload.

[0004] In principle, the acceptance of the community should be carried out by the power supply company on the basis of the developer's self-inspection. However, before the power is turned on, the power supply company cannot effectively control the acceptance process of the developer, resulting in frequent cross-household phenomena after the power is turned on. At this time, the power supply company personnel need to conduct a comprehensive inspection of the entire community, which not only increases the workload but also reduces efficiency.

[0005] Therefore, there is an urgent need for an acceptance tool and means that can be pre-installed by the developer before power is turned on, so that the power supply company can directly determine the inter-household situation after power is turned on. Summary of the invention

[0006] In view of the above problems, the present invention proposes a pre-installed household meter acceptance device, which can be installed before the community is powered on. After power is turned on, the household meter connection situation can be quickly and accurately determined, thereby reducing the acceptance workload and improving the acceptance efficiency and reliability.

[0007] The technical solution adopted by the present invention is as follows: The pre-installed household meter acceptance device includes multiple test terminals, a system master station and at least one mobile terminal. The test terminal is pre-hook in the home of each user to be tested to generate a load signal. The system master station includes a concentrator and a smart meter, which can control the test terminal to generate a load at a specified time, and obtain the subordinate smart meter data through the concentrator, analyze and process the received data, and automatically determine the household meter correspondence. The mobile terminal is used to receive the test sequence and user information issued by the system master station for the test personnel to use on-site.

[0008] After importing the substation archive, the system master station automatically generates a test sequence based on the address, and sends this sequence information and related user information to the mobile terminal. Testers go to the site one by one according to the sequence and information displayed on the mobile terminal, and scan the test terminal with the user through the mobile terminal to bind it. After all the test terminals are bound and hung in the designated user's home, the system master station controls each test terminal to generate a load signal at the specified time according to the generated test sequence table, and obtains the power consumption data of the corresponding meter through the concentrator to further verify the binding relationship between the user and the terminal.

[0009] The test terminal includes a load module, a communication module, a display module and a control module. The load module is used to generate a simulated load, the communication module is used to communicate with the system master station, the display module is used to display the current terminal number and bound user information, and the control module is used to control the working status of the load module. The display module of the test terminal can display at least one of the user address, user house number, user meter number and user account number. The data of the subordinate smart meter obtained by the concentrator may include at least one of the current, active power, reactive power and over-limit events.

[0010] The present invention also provides a method for acceptance of a pre-installed household meter, the main steps of which are as follows: Step S1, import the area file, the system master station automatically generates the test sequence according to the user address, and sends the test user sequence to the mobile terminal; Step S2: The tester goes to the homes of the users to be tested one by one according to the test sequence displayed on the mobile terminal, completes the binding between the terminal and the user by scanning the test terminal, and then attaches the test terminal to the user's home; Step S3, the system master station controls each test terminal to generate a load signal at a specified time according to the load signal schedule; Step S4, the system master station obtains the electricity consumption data of the corresponding smart meter through the concentrator; Step S5: The system master station analyzes and processes the smart meter data to determine whether it is consistent with the test terminal data; Step S6: If the meter data is consistent with the test terminal data, it is determined that the user's household-meter relationship is correct; if not, the system master station controls the concentrator to obtain other meter data from the same centralized meter box until a meter with consistent data is found, and marks the actual household-meter correspondence of the user; Step S7, repeat steps S3 to S6 until the household table relationship of all users is verified.

[0011] In addition, the present invention also has the following preferred embodiment: In step S2, the tester scans the unique identification code on the test terminal through the mobile terminal, and the system main station receives the identification code and establishes an association with the current user to be bound, thereby completing the binding operation between the test terminal and the user conveniently and quickly.

[0012] The system master station automatically plans the optimal test path based on the geographic information in the station area archive, and sends the path to the tester as the test sequence, thereby improving the test efficiency and reducing the workload of the tester.

[0013] After the acceptance is completed, the system master station automatically updates the household-meter relationship information in the substation archives based on the verification results to ensure the accuracy and timeliness of the archive data.

[0014] The beneficial effects of the present invention are: by pre-installing the test terminal in the user's home, and the system master station automatically controls the test terminal to generate load, read the meter data, and analyze and judge the household-meter relationship, the household meter acceptance process is automated and intelligent, greatly improving the acceptance efficiency and accuracy. At the same time, the system master station simplifies the terminal bundling process according to preset rules, solves the cumbersome problems of terminal allocation and on-site search for matching terminals in traditional methods, and further improves work efficiency.

[0015] In addition, the pre-installation test terminal process of the present invention can be completed by the developer, but in fact, the acceptance work should be the responsibility of the developer. After the developer pre-installs the test terminal in the user's home, the power supply company can directly determine the inter-household situation after power is turned on, without additional intervention, which greatly simplifies the acceptance work. At the same time, the power supply company can effectively control the self-inspection process of the developer, prompting it to complete the self-inspection work before power is turned on, thereby providing convenient and efficient support for the subsequent acceptance of the power supply company.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] In the description of the present application, it should be noted that the terms used herein are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings. Example 1

[0025] like Figure 1 As shown, this embodiment provides a preinstalled household meter acceptance device, including multiple test terminals, a system master station and at least one mobile terminal.

[0026] The test terminal is used to generate a load signal and is pre-connected to the home of each user to be tested.

[0027] The system master station includes a concentrator and a smart meter, which can control the test terminal to generate a load signal at a specified time. At the same time, it obtains the power consumption data of the subordinate smart meters through the concentrator, analyzes and processes the received data, and automatically determines the correspondence between the household meter and the user.

[0028] Specifically, after importing the substation archive, the system master station automatically generates a test sequence based on the address, and sends this sequence information and related user information to the mobile terminal. The tester goes to the site one by one according to the sequence and information displayed on the mobile terminal, and scans the test terminal through the mobile terminal to bind it with the user to form a corresponding relationship. The system master station generates a load signal schedule for each test terminal. When all the test terminals are connected to the corresponding user's home, the system master station controls each test terminal to generate a load signal at the specified time according to the signal schedule.

[0029] Furthermore, when importing the substation files, the system master station can import the geographical location distribution map and residential building distribution map of the substation area as needed, and the system master station automatically generates the optimal test path and sends the path to the mobile terminal. The tester can perform on-site testing based on the optimal path.

[0030] For example, this test task is for the XX substation in the XX community. According to the substation archive, buildings 7, 8, and 9 are involved. Combined with the geographical distribution map, it is known that building 7 is near the north gate of the community, building 9 is located in the southeast corner, and building 8 is between buildings 7 and 9. Therefore, the test path planned by the system master station is building 7-8-9.

[0031] At the same time, based on the installation distribution map of residential building user electricity meters, it can be seen that buildings 7, 8, and 9 are all 18 stories high, with 4 households on each floor. Therefore, the system master station plans the route in order from low to high floors, and buildings 7 are arranged in an S shape from the 1st floor to the 18th floor, for example: Building 7 101 - Building 7 102 - Building 7 103 - Building 7 104 - Building 7 204 - Building 7 203 - Building 7 202 - Building 7 201 - ... Building 7 1801, and buildings 8 and 9 follow the same path.

[0032] Furthermore, when multiple testers are testing in the same area at the same time, the system master station will generate two independent optimal test paths based on the geographical location of the area and the distribution map of residential buildings, and send them to the mobile terminals of the corresponding testers to avoid interference. In this example, the test path of Building 7 is sent to Tester No. 1, and the test paths of Buildings 8 and 9 are sent to Tester No. 2.

[0033] The mobile terminal is used to receive the test sequence and user information sent by the system master station, and is used by testers for on-site operation.

[0034] At the same time, the system master station reads the power consumption data of the corresponding smart meter through the concentrator. The data of the subordinate smart meter obtained by the concentrator includes but is not limited to current, active power, reactive power, over-limit events, etc., which are used for comparison and analysis with the load signal of the test terminal; If the meter data is consistent with the test terminal data, it means that there is no cross-user relationship and the correspondence between the household meter and the user is correct; if they are inconsistent, the system master station controls the concentrator to read the data of other meters marked as the same centralized meter box in the file until a meter with consistent data is found. The meter can be determined to be the correct household-meter relationship and the correspondence between the meter and the test terminal can be re-bound.

[0035] In this embodiment, the test terminal includes a load module, a communication module, a display module and a control module. The load module is used to generate a simulated load, that is, to generate a load signal under the control of the system master station, and the simulated signal includes characteristic current, active power, reactive power, etc.

[0036] The communication module is used to communicate with the system master station, receive load control instructions and bound user information, and the communication module adopts one of the mobile communications such as Bluetooth, Lora, small wireless, 4G / 5G, etc.

[0037] The display module is used to display the number of the current test terminal and the bound user information, such as user address, house number, meter number, household number, etc. The tester goes to the designated location for installation according to the user information displayed on the display module.

[0038] The control module controls the operation of the load module according to the load control instruction issued by the master station, and controls the load module to generate corresponding load signals within a specified time period.

[0039] Furthermore, each test terminal includes a unique identification code, through which the tester confirms the identity information of the test terminal and associates and binds it with the corresponding installation user information by scanning the code, manual input or fuzzy matching during the test.

[0040] Through the above device, the corresponding relationship between the household table and the user can be automatically and efficiently verified, solving the problems existing in the prior art. Example 2

[0041] This embodiment provides a pre-installed household meter acceptance method, such as Figure 3 As shown, the following steps are included: Step S1, import the area file, the system main station automatically generates a test sequence according to the user address, and sends each test user sequence to the mobile terminal.

[0042] Take the partial file of No. 1 public transformer in XX District as an example. This file contains the household names, meter numbers, house numbers and other related information of 8 users. After importing the file, the system master station automatically identifies the file address, arranges it in the order of 101-104, 201-204, and sends the arrangement order to the mobile terminal; Step S2: The tester goes to the homes of the users to be tested one by one according to the test sequence displayed on the mobile terminal, completes the binding between the terminal and the user by scanning the test terminal, and hangs the test terminal at the user's home; According to the test sequence of mobile terminal line loss, the tester first came to the door of user 101, randomly took out a test terminal and scanned it, and bound it to user 101. Figure 5 As shown, at this time, a binding relationship is established between the 1101 device and the 101 user, and the test terminal displays the received information on the display module. The displayed content includes the household name, meter number, and house number, etc. Due to the size limitation of the test terminal and the display module, the displayed information can be displayed in a carousel; Go to 102-104, 201-204 in the test order, repeat the above steps, and establish binding relationships with their respective test terminals.

[0043] Since a pre-installed household meter acceptance device needs to install multiple test terminals for one test, the bundling method can randomly select a test terminal for bundling, thereby solving the problem of difficulty in finding numbers or mis-numbering when installing multiple test terminals.

[0044] Step S3: The system master station controls each test terminal to generate a load signal at a specified time according to the load signal schedule; When all test terminals are installed, the master station starts the acceptance task and controls each test terminal to generate load at a specified time, such as Figure 4 As shown, the test terminal 1101 generates a load at 0:05, the test terminal 1102 generates a load at 0:10, and so on, the test terminal 1108 generates a load at 0:40; Considering that the test terminal generates load for a short time, it is necessary to control the concentrator to read the current data of the smart meter during the load duration, which has high requirements for time synchronization and data reading network signal. As a preferred solution, the concentrator can be used to set the smart meter's over-limit event threshold to be less than the load signal strength generated by the test terminal; At this time, when the test terminal generates a load, the corresponding smart meter recognizes a signal higher than the threshold of the over-limit event and automatically generates an over-limit event. Furthermore, the event includes the occurrence time, signal amplitude, and end time; Step S4: The system master station reads the corresponding smart meter over-limit event through the concentrator.

[0045] At this time, since the over-limit events of the electric meter are stored in the smart meter, the concentrator can generate a round of load signals at all test terminals to uniformly read the over-limit events of all smart meters; Step S5: The system master station analyzes and processes the data of the smart meter to determine whether it is consistent with the test terminal data; At this time, the master station only needs to compare the time point at which the load signal occurs at each test terminal in the load signal time table to see if there is an over-limit event in the corresponding smart meter; Step S6: If the load generation time of the test terminal is consistent with the time of the over-limit event of the corresponding smart meter, the household-meter relationship is correct; if not, find other smart meters with over-limit events at the time node and bind them to the corresponding relationship; like Figure 1 As shown, according to the household meter situation in this area, the over-limit event time of the smart meter corresponding to the 1101 / 1105 / 1106 / 1107 / 1108 test terminals corresponds to the load generation time of the five test terminals, so the relationship between the five user meters is correct; The load time generated by the 1102 test terminal is 0:10 minutes. The over-limit event of the corresponding user 2 smart meter is not 0:10 minutes, so the user-meter relationship is abnormal. At this time, the over-limit event time of other smart meters is checked in turn. It is found that the over-limit event time of the smart meter corresponding to user 4 is 0:10 minutes. Therefore, the actual corresponding smart meter of user 2 is 04, and the corresponding relationship is re-bound; Similarly, rebind user 3 to smart meter 02; user 4 to smart meter 03.

[0046] Step S7: Repeat steps S3 to S6 until the household-table relationships of all users are verified to be correct.

[0047] Step S8: Automatically update the household-table relationship information in the substation archive according to the verification result.

[0048] Through the above method, the household meter acceptance work can be completed automatically and efficiently, the work efficiency can be improved, and at the same time, the problems of the trouble of allocating terminals and the trouble of finding corresponding terminals on site in the prior art can be solved. Example 3

[0049] The mobile terminal can also set the test order from bottom to top, from top to bottom, priority to a certain building, or priority to a certain unit as needed. The system master station automatically switches to a certain building, a certain unit, from bottom to top, or from top to bottom according to the file. At this time, the installation of the test terminal can be carried out along the most convenient trajectory for the staff.

[0050] For example, the archives of a certain area show that there are 2 buildings, each with 3 independent units and 10 floors, and the unit numbers are 101~106 to 1001~1006. At this time, the staff can choose to prioritize building 1 and unit 1 from bottom to top, then unit 2 from top to bottom, and unit 3 from bottom to top on the mobile terminal according to their location. At this time, the staff can conveniently install the test terminal along their own trajectory, from 101~102 to 1001~1002 in unit 1 of building 1, then from 1003~1004 to 103~104 in unit 2 of building 1, and then from 105~106 to 1005~1006 in unit 1 of building 1.

[0051] When multiple people are testing, different operators can choose a building or unit to install, thereby improving efficiency.

It should be pointed out that for those skilled in the art, it is still possible to modify the technical solutions recorded in the above-mentioned embodiments, or to replace some of the technical features therein with equivalents.
