Description

Technical Field

[0001] The present invention relates to the technical field of data collection, and in particular to a method for collecting electricity consumption data based on a shared electricity meter. Background Art

[0002] In the power network, the power meter reading concentrator is usually used as the master node, and the power meter equipped with the communication module is used as the slave node to form a communication network to obtain data from each power meter. However, the above communication structure has the following disadvantages in data collection:

[0003] 1) There are too many communication lines. The concentrator needs to establish communication handshakes with all the meters in turn to collect the electricity consumption data on the meters. Therefore, the time for collecting data is greatly affected by the number of meters.

[0004] 2) The collection time is greatly affected by poor communication lines. When some meters have difficulty in exchanging information with the concentrator due to aging hardware or the influence of the surrounding environment, the concentrator needs to wait for a preset time period before it can skip the faulty meter and proceed to collect information from the next meter, which takes a long time.

[0005] Currently, there is no electricity consumption data collection method that has high collection efficiency and will not be affected by too many collection lines and thus affect the data collection efficiency. Summary of the invention

[0006] The content of the present invention is used to introduce the concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of the present invention is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0007] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present invention provide a method for collecting electricity consumption data based on a shared electricity meter, including:

[0008] SO1: The shared meter collects user data and sends it to the storage device for storage;

[0009] SO2: The concentrator visits the shared meters in turn to find the communication lines from the concentrator to the shared meters and from the shared meters to the storage;

[0010] S03: After receiving the instruction to collect power consumption data from the server, the concentrator determines whether the communication line tested in SO2 is unobstructed;

[0011] S04: The concentrator selects the most efficient communication line among the unblocked communication lines to collect the power consumption data in the storage device, thereby completing the power consumption data collection.

[0012] The electricity consumption data collection method provided by the present invention relies on the existing technology of shared electricity meters, such as the patent "Smart meter system with shared storage and display device and sharing method thereof", patent number ZL202110770855.2. With the characteristics that all electricity consumption data on the shared electricity meter are stored in the storage device; when the concentrator needs to collect electricity consumption data, it only needs to find a complete communication line to collect all electricity consumption data; the entire data collection process does not require the establishment of communication lines with all shared electricity meters, which can avoid the time spent on establishing communication handshakes with all shared electricity meters, and can also reduce the waiting time required due to poor communication of some communication lines, thereby increasing the efficiency of the concentrator in collecting electricity consumption data.

[0013] Furthermore, SO2 also includes measuring the communication quality of all the communication lines from the concentrator to the shared electricity meter and from the shared electricity meter to the storage, and making a shared electricity meter information transmission sequence table according to the order of communication quality from high to low.

[0014] Furthermore, SO3 sends an instruction to collect electricity consumption data to the shared electricity meter with the highest communication efficiency according to the arrangement order of the shared electricity meters recorded in the shared electricity meter information transmission sequence table.

[0015] Furthermore, during the period when the concentrator does not receive the collected power consumption data sent by the server, it periodically completes SO2 to update the shared meter information transmission sequence table.

[0016] Furthermore, in SO2, the shared electricity meter information transmission sequence table only records the first three shared electricity meters according to the communication quality.

[0017] Furthermore, in S03, if no smooth communication line is obtained after testing the communication links represented by the three shared meters recorded in the shared meter information transmission sequence table, the communication quality of the communication lines represented by all shared meters is retested to obtain a new shared meter information transmission sequence table, and the new shared meter information transmission sequence table is used to test in turn whether the communication lines represented by the shared meters are smooth.

[0018] Furthermore, the method for ranking the communication quality of the communication lines represented by the shared electricity meter in SO2 includes:

[0019] The concentrator sends a fixed information code to the storage via the communication line represented by the shared meter;

[0020] The storage device compares the received information code with the fixed code sent by the concentrator and evaluates the communication quality through the bit error rate.

[0021] Furthermore, SO4 also includes:

[0022] The storage is divided into a compressed storage area and a normal storage area, wherein the information transmitted from the shared meter to the storage is first stored in the normal storage area, and then after being collected by the concentrator, the information in the normal storage area is saved in the compressed storage area, and the data in the normal storage area is deleted.

[0023] Furthermore, data stored in the normal storage area and sent to the compression storage area needs to be compressed.

[0024] The beneficial effect of the present invention is that it provides a method for collecting electricity data with high collection efficiency and which will not be affected by too many collection lines and thus reduce the data collection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0035] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0036] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0037] refer to Figure 1 :In the power network system, the concentrator is the main node for meter data collection, and the meter is the sub-node for data collection. When the power company's server needs to collect power consumption data, it sends a command to the concentrator, and then the concentrator sends a command to collect data to the meter, and then the meter sends the corresponding data to the concentrator in sequence or at the same time. In this mode, the following situations will occur:

[0038] 1. There are too many meters. The meters and concentrators need to perform identity authentication and complete communication handshake every time, so the meter reading time is long. When all meters upload data to the concentrator at the same time, it is easy to cause data congestion and communication delay.

[0039] 2. When the communication between some meters and the concentrator is blocked due to hardware problems or environmental reasons, such as hardware aging or the appearance of new electromagnetic devices around the meters, the concentrator needs to wait for the communication with the meter to be completed or for a preset time to be reached before it can establish a communication connection with the next meter to collect the required data. Therefore, the meter reading time is very long.

[0040] Embodiment 1:

[0041] To this end, the present invention constructs a method for collecting electricity consumption data using a shared electricity meter as an electricity meter system, wherein the shared electricity meter is an existing technology, which can refer to the smart meter system described in Chinese patent document: CN113406375B smart meter system with shared storage and display device and its sharing method.

[0042] A shared electricity meter is a device in which multiple electricity meters share a display and storage. The storage is used to store the user's electricity usage information, and the display is used to display the user's electricity usage information after obtaining permission, thus preventing criminals from obtaining electricity usage information.

[0043] To this end, the present invention designs a method for information connection between the storage and the concentrator based on the characteristic that the shared electricity meter has a common storage, so as to reduce the number of information connections between the concentrator and the shared electricity meter when the concentrator collects meter data.

[0044] The initial idea of ​​this method is to connect the storage and concentrator of a smaller number of shared electricity meters to each other, which can increase the communication efficiency. However, if the storage and concentrator are directly connected for signal connection, the following problems will arise:

[0045] 1. Increased cost: It is necessary to add a device to the storage device that can connect the signal to the concentrator. The device needs to have good stability, which will lead to increased costs.

[0046] 2. The risk of line breakage increases, because the shared meters under the same storage are directly transmitted to the concentrator through the storage. After the communication line between the storage and the concentrator is disconnected, it will inevitably lead to the data of all shared meters under the storage being unable to be uploaded to the storage normally.

[0047] The structural diagram of the concentrator, the shared meter and the storage of the shared meter set up on the basis of the shared meter technology is as follows Figure 2 shown.

[0048] refer to Figure 3 , the meter data collection method based on the shared meter includes:

[0049] S1: storage collects and stores shared meter data;

[0050] The shared electricity meter sends the electricity consumption data to the storage device, and the storage device receives and stores the data sent by the shared electricity meter;

[0051] S2: The concentrator searches for a communication line;

[0052] The concentrators share the meters one by one, and look for communication lines from the concentrator to the shared meters and from the shared meters to the storage;

[0053] S3: The concentrator determines whether the communication line is unobstructed;

[0054] After receiving the instruction to collect power consumption data from the server, the concentrator determines whether the communication line tested in SO2 is unobstructed;

[0055] The shared meter that receives the electricity consumption data collected by the concentrator sends an information access instruction to the storage. If the shared meter receives the access permission signal sent by the storage, the shared meter sends a signal that the communication line is normal to the concentrator; if the concentrator receives the signal that the communication line is normal, the next step is executed. If the concentrator does not receive the signal that the communication line is normal, the shared meter is recorded and S2 is executed again to ensure that the concentrator receives the signal that the communication line is normal from at least one shared meter.

[0056] S4: Establish signal lines from the concentrator to the shared meter and from the shared meter to the storage to complete data transmission;

[0057] After the concentrator obtains the signal that the communication line from the concentrator to the shared meter and from the shared meter to the storage is normal, the concentrator uses the communication line to establish a signal connection with the storage, and then collects the electricity consumption data of all the shared meters stored in the storage.

[0058] To this end, the method designed by the present invention has the following advantages:

[0059] (1) When the concentrator collects data from the smart meter, the communication line between the smart meter and the concentrator can be used to transmit data between the storage and the concentrator. There is no need to set up additional communication equipment and communication lines between the concentrator and the storage, which saves costs.

[0060] (2) It avoids the problem of low communication efficiency caused by multiple signal transmission lines between traditional electricity meters and concentrators;

[0061] (3) It avoids the problem of a single communication line caused by directly adopting a signal connection between the storage and the concentrator, and prevents the problem that after the communication line between the storage and the concentrator is disconnected, the power consumption data of the shared electricity meter under the storage is difficult to be transmitted to the concentrator.

[0062] Furthermore, in practice, a shared electric meter that records an incomplete signal connection can be recorded as a faulty device, and specialized personnel can be scheduled to perform maintenance at regular intervals.

[0063] Embodiment 2:

[0064] The communication connection between the shared meter and the concentrator is not stable. Due to the influence of hardware quality, installation method, and surrounding environment, the stability of the signal connection between the shared meter and the concentrator is not the same. Therefore, there is a gap in the efficiency of information transmission and communication quality between different concentrators and shared meters.

[0065] To this end, in response to this situation, Example 2, based on Example 1, compares the communication lines from the concentrator to the shared electricity meter and from the shared electricity meter to the storage, and selects the most efficient communication lines from the concentrator to the shared electricity meter and from the shared electricity meter to the storage. When the concentrator receives an instruction from the server to collect electricity consumption data, the electricity consumption data of all shared electricity meters stored in the storage are collected through the selected most efficient communication lines.

[0066] refer to Figure 4 , the meter data collection method based on the shared meter includes:

[0067] S1: storage collects and stores meter data;

[0068] The shared electricity meter collects user data and sends it to the storage device for storage;

[0069] S2: The concentrator makes a transmission sequence table of shared meter information;

[0070] During the non-information collection time when the concentrator does not receive the collected power consumption data sent by the server, the concentrator measures the communication quality of all the communication lines from the concentrator to the shared meter and from the shared meter to the storage, and makes a shared meter information transmission sequence table based on the order of communication quality from high to low;

[0071] For example, the concentrator measures that the communication quality of all meters 1 to k under the storage is meter 3, meter 2, meter 3, etc. from high to low, and then creates a shared meter information transmission sequence table in this order, as shown in the following table:

[0072] Electricity meter sequence Communication quality Electricity meter 3 Electricity Meter 2 Electricity meter 1 …… ……

[0073] S3: Update the shared meter information transmission sequence table;

[0074] During the non-information collection time when the concentrator does not receive the collected electricity consumption data sent by the server, it periodically repeats S2 to periodically update the above-mentioned shared meter information transmission sequence table;

[0075] S4: The concentrator searches for the optimal communication line;

[0076] The concentrator selects the most efficient communication line among the unobstructed communication lines to collect the power consumption data in the storage device, thereby completing the power consumption data collection.

[0077] After receiving the instruction to collect meter data from the server, the concentrator sends the instruction to collect electricity data to the shared meter with the highest communication efficiency according to the arrangement order of the shared meters recorded in the latest shared meter information transmission sequence table;

[0078] S5: The concentrator determines whether the communication line is on or off;

[0079] After the shared electricity meter receives the instruction for collecting electricity consumption data sent by the concentrator, the shared electricity meter sends an information access instruction to the storage. After the shared electricity meter obtains the instruction for allowing access fed back by the storage, the shared electricity meter feeds back a signal that the communication line is normal to the concentrator. If the concentrator receives the signal that the communication line is normal, the next step is executed. If the concentrator does not receive the signal that the communication line is normal, S4 is re-executed, and then according to the arrangement order of the shared electricity meters recorded in the selected shared electricity meter information transmission sequence table, the concentrator sends the instruction for collecting electricity consumption data to the shared electricity meter, thereby ensuring that the concentrator receives the signal that the communication line is normal from at least one shared electricity meter.

[0080] For example, the concentrator sends an instruction to collect electricity usage data to the first shared meter in the order of the shared meters recorded in the shared meter information transmission sequence table. After receiving the instruction to collect electricity usage data sent by the concentrator, the first shared meter sends an information access instruction to the storage. After the shared meter obtains the instruction to allow access fed back by the storage, if the concentrator does not receive the signal from the first shared meter indicating that the communication line is normal; the concentrator sends the instruction to collect electricity usage data to the second shared meter in the order of the shared meters recorded in the shared meter information transmission sequence table. If the concentrator still does not receive the signal from the second shared meter indicating that the access is allowed, the concentrator sends the instruction to collect electricity usage data to the third shared meter, and so on, until the concentrator receives a signal from a shared meter indicating that the communication line is normal.

[0081] S6: Transmit electricity consumption data;

[0082] After receiving a signal indicating that the communication line is normal, the concentrator uses the communication line to establish a signal connection with the storage device, and then collects the electricity consumption data of all shared electricity meters stored in the storage device.

[0083] Furthermore, the method for measuring communication quality in S2 is:

[0084] Step 1: The concentrator sends a fixed information code to the storage through the communication line represented by the shared meter;

[0085] Step 2: The storage device compares the received information code with the fixed code sent by the concentrator, and evaluates the communication quality through the bit error rate.

[0086] For example, the concentrator sends 1000 strings of information codes to the storage through the communication line represented by the shared electricity meter 1, and the storage only receives 980 correct information codes.

[0087] Then the concentrator sends 1000 strings of information codes to the storage through the communication represented by shared meter 2. The storage only receives 950 correct information codes. Therefore, the communication quality of the communication line represented by shared meter 2 is lower than the communication quality of the communication line represented by shared meter 1.

[0088] Embodiment three:

[0089] In practice, the storage device usually has multiple shared meters under its jurisdiction. If the communication quality of the communication lines represented by all the shared meters is tested, it is usually not necessary to consider the communication efficiency of the shared meters that exceed a certain ranking. Therefore, in this embodiment, the shared meter information transmission sequence table only records the first three digits. In addition, it can be foreseen that when the server issues information instructions to collect the shared meters stored in the storage device, if the on / off of the communication lines represented by the shared meters are measured in sequence according to the order of the shared meter information transmission sequence table, and the communication lines are found to be disconnected, it is possible to suspect that the shared meter information transmission sequence table obtained by the concentrator in the latest measurement is incorrect. At this time, it is necessary to restart the measurement of the communication quality of the communication lines represented by all the shared meters to form a new shared meter information transmission sequence table, and re-judge the on / off of the communication lines in sequence according to the new shared meter information transmission sequence table.

[0090] Specific:

[0091] S1: storage collects and stores meter data;

[0092] The shared electricity meter sends the electricity usage data to the storage device for storage;

[0093] S2: The concentrator makes a transmission sequence table of shared meter information;

[0094] During the non-information collection time when the concentrator does not receive the collected power consumption data sent by the server, it measures the communication quality of all the communication lines from the concentrator to the shared meter and from the shared meter to the storage, and makes a shared meter information transmission sequence table according to the order of communication quality from high to low. The shared meter information transmission sequence table only records the first three shared meters according to the communication quality.

[0095] S3: Update the shared meter information transmission sequence table;

[0096] During the non-information collection time when the concentrator does not receive the collected electricity consumption data sent by the server, it periodically repeats S2 to periodically update the above-mentioned shared meter information transmission sequence table;

[0097] S4: The concentrator searches for the optimal communication line;

[0098] After receiving the instruction to collect meter data from the server, the concentrator sends the instruction to collect electricity data to the shared meter with the highest communication efficiency according to the arrangement order of the shared meters recorded in the latest shared meter information transmission sequence table;

[0099] S5: The concentrator measures the communication lines represented by the shared meters in sequence according to the shared meter information transmission sequence table, and determines whether the communication lines are connected or disconnected;

[0100] After the shared electricity meter receives the instruction for collecting electricity consumption data issued by the concentrator, the shared electricity meter sends an information access instruction to the storage. After obtaining the instruction allowing access fed back by the storage, the shared electricity meter feeds back a signal that the communication line is normal to the concentrator. If the concentrator receives the signal that the communication line is normal, S7 is executed. If the concentrator does not receive the signal that the communication line is normal, the concentrator sends the instruction for collecting electricity consumption data to the next shared electricity meter with the highest communication efficiency according to the arrangement order of the shared electricity meters recorded in the selected shared electricity meter information transmission sequence table. If after testing the communication links represented by the three shared electricity meters recorded in the shared electricity meter information transmission sequence table, no smooth communication line is obtained, S6 is executed.

[0101] S6: The concentrator executes step S2, that is, retests the communication quality of the communication lines represented by all shared meters to obtain a new shared meter information transmission sequence table, and uses the new shared meter information transmission sequence table to test whether the communication lines represented by the shared meters are unobstructed in turn to obtain the latest shared meter information transmission sequence table, and then repeats step S4 according to the latest shared meter information transmission signal table until the concentrator receives a signal from a shared meter that the communication line is normal.

[0102] For example, when executing S5, the concentrator measures the communication lines represented by all shared meters in sequence according to the order of the shared information transmission sequence table. After not receiving feedback that the communication lines are normal, the concentrator executes step 2 to update a new shared meter information transmission sequence table. Then, according to the order of the shared meters recorded on the new shared meter information transmission sequence table, the concentrator measures whether the communication lines represented by the shared meters are on or off in sequence, so as to find out whether the lines from the concentrator to the shared meters and from the shared meters to the storage are normal.

[0103] S7: Transmit electricity consumption data;

[0104] After receiving a signal indicating that the communication line is normal, the concentrator uses the communication line to establish a signal connection with the storage device, and then collects the electricity consumption data of all shared electricity meters stored in the storage device.

[0105] refer to Figure 6: In a more specific embodiment, in order to further increase the signal transmission rate, the storage is divided into a normal storage area and a compressed storage area, wherein the information transmitted from the shared meter to the storage is first stored in the normal storage area, and then collected by the concentrator, saved in the compressed storage area, and the data in the normal storage area is deleted, and the data stored in the normal storage area and sent to the compressed storage area needs to be compressed.

[0106] Therefore, the compressed storage area stores the electricity consumption data of the shared meter that the concentrator has collected once. These electricity consumption data are stored in the storage module of the storage in a compressed manner. The normal storage records the data sent to the storage by the shared meter. When the concentrator does not collect the data recorded in the normal storage area, the data in the normal storage area is always stored in this area. After the concentrator collects part or all of the data in the normal storage area, the data collected by the concentrator in the normal storage is compressed and stored in the compressed storage area of ​​the storage, and the data collected by the concentrator in the normal storage area is deleted. Therefore, when this solution is adopted, when the concentrator collects information in the storage, it does not need to decompress the information received from the storage, which can increase the transmission efficiency.

[0107] The electric meter data collection method based on shared electric meter provided by the present invention has the following advantages:

[0108] (1) During non-data collection time, the concentrator measures the communication lines from the concentrator to the shared meter and from the shared meter to the storage in turn, and selects the communication line with the highest communication efficiency; in this way, the signal transmission efficiency can be increased to the maximum extent.

[0109] (2) During non-data collection periods, the shared meter data transmission table is periodically updated to ensure the timeliness of the shared meter data transmission table. This can prevent the shared meter with high transmission efficiency from becoming a shared meter with low transmission efficiency due to changes in the surrounding environment of the shared meter or aging or sudden damage of the internal components of the shared meter, and the communication line is not changed in time, resulting in low transmission efficiency.

[0110] (3) When screening communication lines, the concentrator selects different communication lines to send the same information code, and the quality of the communication line is judged by the received information code, so the line with the best communication quality can be screened out.

[0111] (4) The shared information transmission sequence table only records the first three shared meters, which can timely trigger the matrix of updating the shared information transmission sequence table. When performing the continuity test of the communication line, if the communication lines indicated by the first three shared meters cannot communicate normally, it means that there must be a problem with the latest shared information transmission sequence table, so the communication lines represented by all shared meters can be tested in a timely manner.

[0112] (5) Dividing the storage into a normalized storage area and a compressed storage area can increase the efficiency of information transmission. When the concentrator collects data in the normalized storage area, it does not need to perform additional decompression work, so the information transmission efficiency is higher.
