[0031] Through the above technical scheme, the water meter reading system can integrate mobile meter reading equipment and fixed meter reading equipment, not only support manual and automatic meter reading, but also enable data to verify each other, thereby improving the accuracy and tamper-proof of data. By uploading data to the data center for analysis and processing to detect abnormalities, the optional communication connection between the mobile meter reading equipment and the fixed meter reading equipment provides additional flexibility, which can be adjusted according to actual needs, thereby optimizing resource utilization and improving work efficiency. In addition, the location of the meter reader can be determined through the positioning module to monitor his work efficiency.

[0032] Furthermore, the water meter reading system also includes a meter reading strategy, including the following steps: A1, the data center 30 communicates with each of the fixed meter reading devices 20 at a preset operation monitoring time every day and generates a list of hardware abnormal devices; The operation monitoring time is a preset time, which can be set manually, and is used to detect the communication status of all the fixed meter reading devices 20 at a fixed time every day to find out whether there is an abnormality in the communication hardware. For example, the operation monitoring time can be set before the staff goes to work, so that the staff can technically repair the abnormal equipment after work; The hardware abnormal device list is an information list of each of the fixed meter reading devices 20 with communication abnormalities, which may include the device number, address information, location information and corresponding user information of the hardware abnormal device 20, so as to facilitate identification and maintenance by the staff; There are many ways to monitor whether there is communication anomaly in each of the fixed meter reading devices 20. The data center 30 can send a detection data packet to each of the fixed meter reading devices 20 and wait to receive its return data, and judge whether its communication is smooth based on the time difference between sending and returning. It can also be set that each of the fixed meter reading devices 20 sends a detection data packet at a fixed time, and judge its communication status based on the time of receipt.

[0033] A2, each of the fixed meter reading devices 20 sends the corresponding daily metering data to the data center 30 at a preset data sending time every day; The data transmission time is a pre-selected time, which is used to enable each of the fixed meter reading devices 20 to send corresponding metering data to the data center 30 at a fixed time every day for analysis and archiving; The daily metering data is the water consumption data collected by each of the fixed meter reading devices 20 within one day before the data sending time.

[0034] A3, the data center 30 generates a list of abnormal metering devices according to the daily metering data of each fixed meter reading device 20; The abnormal metering equipment list is an information list of each of the fixed meter reading equipment 20 having suspicious metering conditions; By analyzing the daily metering data and the corresponding historical metering data of each of the fixed meter reading devices 20, it is possible to determine the fixed meter reading devices 20 that may have metering anomalies, so as to perform manual investigation; A variety of statistical methods can be used to determine whether there are abnormalities in the current day's metering data. For example, the historical weighted average can be used to determine whether the current day's metering data deviates too much, and the confidence interval algorithm can be used to determine whether the current metering data is outside the confidence interval. Both methods can be used to determine abnormal values ​​and then identify abnormal equipment.

[0035] A4, the data center 30 generates a list of devices to be checked based on the hardware abnormality device list and the metering abnormality device list; The list of equipment to be checked is a collection of the list of equipment with hardware abnormalities and the list of equipment with measurement abnormalities, so that staff can conduct equipment inspections based on the list.

[0036] A5, the data center 30 determines the corresponding meter reading group positioning information according to the preset meter reading partition information and the positioning information corresponding to each of the fixed meter reading devices 20; Meter reading partition information is the geographical division area information of the pre-set management area, which is used to determine the corresponding work areas of different staff members and can be manually set according to needs and actual conditions; The meter reading group positioning information is group information determined based on the positioning information corresponding to each of the fixed meter reading devices 20 and the meter reading partition information, that is, if the positioning information corresponding to the fixed meter reading device 20 is located in a partition in the meter reading partition information, it is allocated to the group corresponding to the partition.

[0037] A6, the data center 30 sends the location information of each meter reading group to the corresponding mobile meter reading device 10; The meter reading group positioning information is sent to the mobile meter reading device 10 held by the corresponding staff, so that the staff can perform manual meter reading operations on each fixed meter reading device 20 in the meter reading group positioning information according to the meter reading group positioning information.

[0038] A7, the mobile meter reading device 10 generates meter reading route information according to its own mobile device positioning information and corresponding meter reading group positioning information; The mobile device positioning information is positioning data acquired by the mobile meter reading device 10 through its own mobile device positioning module 12 to reflect the current positioning information of the staff; According to the mobile device positioning information, i.e., the current positioning of the staff and the positioning information of each fixed meter reading device 20 in the meter reading group positioning information, a reasonable moving path can be generated through a variety of algorithms to minimize the moving distance of the staff and improve work efficiency; There are many algorithms that can be used to calculate a more reasonable moving path, for example, the nearest neighbor algorithm (Nearest Neighbor Algorithm), the minimum spanning tree (Prim or Kruskal algorithm), the genetic algorithm, etc.

[0039] A8, the staff carries the corresponding mobile meter reading device 10 according to the meter reading route information in turn for each of the fixed meter reading devices 20 in the meter reading group positioning information to perform meter reading operations; The staff reads the meter of the fixed meter reading device 20 in sequence according to the meter reading route information.

[0040] A9, if each of the fixed meter reading devices 20 in the meter reading group positioning information exists in the list of devices to be checked, the staff performs maintenance work on the fixed meter reading device 20; For each of the fixed meter reading devices 20 in the list of devices to be checked, the staff performs inspection and maintenance while performing the meter reading operation, and attempts to determine or eliminate the abnormal situation.

[0041] Through the above steps, the water meter reading system can timely identify and list hardware anomalies and metering abnormalities through daily data collection and abnormality monitoring, so as to accurately locate the equipment that needs maintenance. In addition, the data center can intelligently generate meter reading routes based on the geographical location information of each meter reading device, optimize the meter reading routes of the staff, and check and repair the abnormal fixed meter reading equipment while the staff is reading the meter, so as to ensure the efficiency and systematicness of meter reading and maintenance work.

[0042] Furthermore, the meter reading strategy also includes the following steps for generating a list of hardware abnormal devices: B1, obtaining the data communication address corresponding to each of the fixed meter reading devices 20 from a preset water meter information database; The water meter information database is a pre-set database used to store various relevant data; The data communication address is the data communication address of each of the fixed meter reading devices 20, such as an IP address, etc. There may be different communication address formats for communication protocols of different communication hardware.

[0043] B2, sending preset detection information to the data communication address of each of the fixed meter reading devices 20, and recording the corresponding sending time; The detection information is a pre-set information data packet with identification. For example, the detection information is a specific content. After receiving the detection information, the fixed device communication module 26 of the fixed meter reading device 20 will send a specific data packet back to the data center 30 to confirm that it has received the detection information. The sending time is the time when the data center 30 sends the detection information to the fixed meter reading device 20 .

[0044] B3, waiting for and receiving the response information returned by the data communication address of each of the fixed meter reading devices 20, and recording the corresponding receiving time; The response information is a pre-set information data packet with identification, which is used to be sent back to the data center 30 to confirm that the fixed meter reading device 20 has received the detection information; The receiving time is the time when the data center 30 receives the response information.

[0045] B4, determining the corresponding information round-trip delay according to the corresponding sending time and receiving time of each of the fixed meter reading devices 20; The round-trip delay of information is the time between the time it is sent and the time it is received.

[0046] B5, determining a corresponding communication distance according to the positioning information of each of the fixed meter reading devices 20 and the positioning information of the data center 30; The communication distance is the geographical distance between the fixed meter reading device 20 and the data center 30, which can be determined by calculating the respective positioning information.

[0047] B6, calculating the corresponding response speed according to the round-trip delay and communication distance corresponding to each of the fixed meter reading devices 20; The response speed is the data transmission speed between the fixed meter reading device 20 and the data center 30. If there is an abnormality in the communication hardware, the response speed may be affected. The response speed can be determined by dividing twice the communication distance by the round-trip delay.

[0048] B7, if the response speed of the fixed meter reading device 20 is less than a preset response speed threshold, generating corresponding hardware abnormal device information according to the identification information and positioning information of the fixed meter reading device 20; The response speed threshold is a preset reference value used to determine whether the response speed of the fixed meter reading device 20 is abnormal; The identification information is the identification information of the fixed meter reading device 20, which is used for unique identification; The hardware abnormality device information is the device information of the fixed meter reading device 20 with an abnormality, which is a collection of identification information and positioning information.

[0049] B8, generates a hardware abnormal device list based on all abnormal device information.

[0050] Combine all abnormal device information to generate a hardware abnormal device list.

[0051] Through the above steps, the water meter reading system can evaluate the equipment performance by combining the positioning information of the fixed meter reading equipment and calculating the information round-trip delay and communication distance to find equipment with hardware abnormalities, so as to carry out maintenance in advance, prevent data loss and service interruption, ensure the stable operation and data accuracy of the entire water meter system, and improve the reliability and maintenance efficiency of the water meter reading system.

[0052] Furthermore, the meter reading strategy further includes the following steps for generating a list of abnormal metering devices: C1, obtaining historical daily metering data corresponding to each of the fixed meter reading devices 20 from the water meter information database; The historical daily metering data is the daily metering data collected by the fixed meter reading device 20 in the past.

[0053] C2, obtaining corresponding review day metering data from the historical daily metering data corresponding to each of the fixed meter reading devices according to a preset data review cycle; The data review period is a pre-set duration used to determine the corresponding data range. For example, the data review period can be set to 30 days, and the historical daily measurement data within these 30 days will be used as the basis for analysis; The review daily measurement data refers to the data within the data review period of the historical daily measurement data.

[0054] C3, calculate the daily measurement mean based on the average of the reviewed daily measurement data; The daily measurement mean is the mean of the retrospective daily measurement data.

[0055] C4, calculate the daily measurement standard deviation based on the reviewed daily measurement data and the daily measurement mean; The daily measurement standard deviation is the standard deviation of the daily measurement data.

[0056] C5, calculate the corresponding reasonable daily water consumption range based on the daily measurement mean and daily measurement standard deviation; The reasonable daily water consumption range is the corresponding reasonable data range determined based on the review daily metering data; The reasonable daily water consumption range can be determined by calculating the confidence interval based on the daily measurement mean and daily measurement standard deviation; The corresponding normal distribution probability range can also be calculated based on the daily measurement mean and daily measurement standard deviation to determine the reasonable daily water consumption range. For example, based on the normal distribution, about 95% of the data fall within the range of plus or minus two times the standard deviation of the mean, that is, [𝜇−2𝜎,𝜇+2𝜎], or about 99.7% of the data fall within the range of plus or minus three times the standard deviation of the mean, that is, [𝜇−3𝜎,𝜇+3𝜎], where 𝜇 is the mean and 𝜎 is the standard deviation; Based on the above methods and other feasible statistical methods, the corresponding data range can be calculated as a basis for judgment.

[0057] C6, if the daily water consumption is not within the reasonable daily water consumption range, then generate corresponding abnormal metering device information according to the identification information and positioning information of the fixed meter reading device 20; The abnormal metering device information is the device information of the fixed meter reading device 20 with abnormal metering data, which is a collection of identification information and positioning information. C7, generates a list of measurement abnormal equipment based on all measurement abnormal equipment information.

[0058] The abnormal metering equipment list is a collection of all abnormal metering equipment information.

[0059] Through the above steps, the water meter reading system can analyze the historical daily metering data and the current day metering data of the fixed meter reading equipment, and define a reasonable daily water consumption range based on this to determine whether the fixed meter reading equipment may have metering anomalies, and record the detailed information of the equipment for further investigation, so as to quickly identify possible metering problems, so as to carry out maintenance or adjustments in time to prevent the accumulation of data errors from affecting the operation of the entire water meter system.

[0060] Furthermore, the meter reading strategy further includes the following steps for the mobile meter reading device to perform meter reading operations: D1, the staff uses the mobile meter reading device 10 to shoot the appearance of the fixed meter reading device 20 to obtain device appearance video data; The device appearance video data is an appearance video of the fixed meter reading device 20. The staff operates the mobile meter reading device 10 and collects and generates the data through the camera module 11 of the mobile meter reading device 10, and uploads it to the data center 30 for archiving and future reference. Through the appearance image, the background staff or a specific algorithm program can perform a preliminary screening based on the appearance image to determine whether there is any abnormality in the fixed meter reading device 20, or compare it with historical images to find abnormalities.

[0061] D2, the staff uses the mobile meter reading device 10 to photograph the identification module 22 and the reading module 23 of the fixed meter reading device 20 to obtain corresponding identification images and meter display reading images; The identification image is image information set on the identification module 22, which is used to identify the mobile meter reading device 10, such as a number, etc. The identification image can be a unique barcode, a two-dimensional code, etc., which is used to determine the relationship between the corresponding fixed meter reading device 20 and the user. The identification image can be encrypted to prevent the number from being leaked and the metering data from being tampered with in a targeted manner; The image showing the reading is image data of the reading displayed by the fixed meter reading device 20, and is used to be uploaded to the data center 30 for archiving and future reference.

[0062] D3, the mobile meter reading device 10 obtains corresponding identification information through identification image recognition and defines it as current water meter identification information; The current water meter identification information is the identification information of the fixed meter reading device 20 corresponding to the current meter reading operation. By parsing or decrypting the identification image, the corresponding identification information can be matched with the water meter information database.

[0063] D4, obtaining the data communication address corresponding to the fixed meter reading device 20 from the water meter information database according to the current water meter identification information and defining it as the current water meter communication address; The current water meter communication address is the data communication address corresponding to the fixed meter reading device 20 corresponding to the current meter reading operation.

[0064] D5, establishing a communication connection with the fixed device communication module 26 of the fixed meter reading device 20 through the mobile device communication module 14 of the mobile meter reading device 10 according to the current water meter communication address to obtain on-site collected metering data; The metering data collected on-site is metering data obtained by direct communication between the mobile meter reading device 10 and the fixed meter reading device 20, which can reduce or avoid errors or mistakes caused by data forwarding.

[0065] D6, the mobile meter reading device 10 obtains the mobile device positioning information corresponding to the current position and defines it as the current meter reading positioning information; The current meter reading location information is location information when the staff operates the mobile meter reading device 10 to perform meter reading operations.

[0066] D7, adding on-site collected metering data and current meter reading location information to the meter display reading image; By adding the metering data collected on site and the current meter reading location information to the meter display reading image, the subsequent manual comparison of metering data and meter display data becomes intuitive, and the algorithm or program can also easily identify and read the corresponding metering data and location information directly from the image. Secondly, the content added to the image is also difficult to be modified, ensuring the authenticity of the data; Among them, the metering data collected on-site and the current meter reading location information can be added to the meter reading image in the form of a text watermark, or it can be some kind of encrypted image, such as an encrypted QR code, encrypted barcode, etc., which can further improve the data's anti-tampering performance.

[0067] D8, generating meter reading media data based on the combination of appearance video data and meter display reading image; The meter reading media data is a collection of appearance video data and meter display reading images, and may be compressed or encrypted data to prevent data leakage.

[0068] D9, sending the current water meter identification information and the corresponding meter reading media data to the data center 30 through the mobile meter reading device 10.

[0069] The current water meter identification information and the corresponding meter reading media number are matched and sent to the data center 30 so that the data can be correctly stored accordingly.

[0070] Through the above steps, the water meter reading system can combine the metering data obtained by direct communication between the mobile meter reading device and the fixed meter reading device with the meter display reading image, so as to ensure the integrity of the meter reading data, and can also automatically identify and record the identification information of the water meter through image recognition technology, match the data to the correct corresponding water meter, reduce manual entry errors, optimize the meter reading process, reduce the burden on staff, and improve the reliability of the service.

[0071] Furthermore, the meter reading strategy further includes the following steps for sending the meter reading media data to the data center 30: E1, the mobile meter reading device 10 generates a corresponding original data summary field using a preset summary algorithm according to the meter reading media data corresponding to the current water meter identification information; The digest algorithm is a pre-set algorithm used to generate a corresponding irreversible data digest based on the data. The data digest generated by the previous and next data can be compared to determine whether the data has been modified. The existing digest algorithms include MD5, SHA, MAC, etc., which can generate corresponding data digests. The original data summary field is a summary data field generated corresponding to the meter reading media data through a summary algorithm.

[0072] E2, combining the current water meter identification information and the original data summary field and sending them to the data center 30; After the original data summary field is generated, it is immediately matched with the current water meter identification information and sent to the data center 30, so that the data center 30 can immediately determine the data summary corresponding to the subsequent meter reading media data to be sent. On the one hand, it can prevent abnormalities in data transmission, and on the other hand, it can also prevent data from being tampered with. In addition, the amount of data summary is usually very small, and can be quickly transmitted to the data center 30, and it is not easy to make errors.

[0073] E3, generating meter reading ciphertext data according to the meter reading media data using a preset encryption algorithm; The encryption algorithm is a pre-selected algorithm used to encrypt data to prevent data leakage and tampering; The meter reading ciphertext data is the meter reading media data generated through encryption.

[0074] E4, generating a plurality of meter reading ciphertext data blocks according to the meter reading ciphertext data by using a preset data block algorithm; The data block algorithm is a pre-set algorithm used to divide the enlarged data into blocks to facilitate subsequent data transmission; The meter reading ciphertext data blocks are data blocks generated after the meter reading ciphertext data is processed through a block algorithm.

[0075] E5, sending each meter reading encrypted data block to the data center 30 in sequence; Block transmission can reduce the pressure on the communication bandwidth of the data center 30, especially when multiple workers are performing meter reading operations, sending large-volume video data will occupy more bandwidth.

[0076] E6, the data center 30 generates meter reading media recovery data by combining and decrypting each meter reading ciphertext data block; The meter reading medium recovery data is data generated by the data center 30 according to the received data block combination and decryption.

[0077] E7, generating a summary field of restored data by using a summary algorithm according to the restored data from the meter reading media; The restored data summary field is a summary data field corresponding to the meter reading media restored data.

[0078] E8, if the original data summary field and the restored data summary field are consistent, the meter reading media restored data is retained.

[0079] If the restored data summary field is consistent with the previously received original data summary field, it means that the received data is consistent with the sent data, and it can be determined as accurate data and stored; If the restored data summary field is inconsistent with the previously received original data summary field, it means that the received data may be erroneous or tampered with, and the received data should be discarded and retransmitted.

[0080] Through the above steps, the water meter reading system can ensure that the data has not been tampered with during transmission by verifying the consistency between the original data summary field and the restored data summary field of the meter reading media data, thereby ensuring the integrity and reliability of the data, improving the security standard of data processing, ensuring the accuracy and trustworthiness of the meter reading data, and providing data security support for the water meter reading system.

[0081] Furthermore, the meter reading strategy further comprises the following steps: F1, after the meter reading operation is completed, the mobile meter reading device 10 determines the next meter reading location information according to the meter reading route information; The next meter reading location information is the location information of the next fixed meter reading device 20 that needs to perform a meter reading operation, which is determined according to the meter reading route information.

[0082] F2, the mobile meter reading device 20 continuously obtains the current location information of the mobile device; The current positioning information of the mobile device is the real-time positioning information of the mobile meter reading device 20 to reflect the current position of the mobile meter reading device 20, that is, the current position of the staff.

[0083] F3, calculating the corresponding departure distance according to the current positioning information of the mobile device and the current meter reading positioning information; The departure distance is the distance between the fixed meter reading device 20 and the mobile meter reading device 20 corresponding to the current meter reading operation, and can be calculated based on the positioning data of the two.

[0084] F4, if the distance is greater than the preset device distance threshold, the mobile meter reading device 10 sends each meter reading ciphertext data block and the current location information of the mobile device to the data center in sequence at a preset sending interval; The device distance threshold is a preset reference distance value, which is used to determine whether the staff has completed the meter reading operation and left the current fixed meter reading device 20. The device distance threshold can be manually set based on experience or device error; The sending interval is a preset time interval, which is used to determine the time interval between sending two meter reading ciphertext data blocks, and can be set manually based on experience or based on the bandwidth load of the data center 30; When the departure distance is greater than the device distance threshold, that is, the staff is judged to have completed the current meter reading operation and may be heading to the location of the next meter reading operation, it indicates that the mobile meter reading device 10 is in a certain idle state, and the meter reading ciphertext data blocks can be sent at this time, and the current positioning information and the meter reading ciphertext data blocks can be obtained and sent in combination at the same time. The positioning data can be used for staff tracking at the same time, and additional feature quantities can be added to the meter reading ciphertext data blocks to facilitate data tracing.

[0085] F5, if the distance is greater than the preset device distance threshold, and the encrypted data of each meter reading has been sent in blocks, the current location information of the mobile device is sent to the data center 30 at a sending interval; If all the encrypted data blocks of meter reading have been sent, only the positioning data is sent to the data center 30 for tracking of the staff.

[0086] F6, calculating the corresponding approach distance according to the current positioning information of the mobile device and the positioning information of the next meter reading; The approach distance is the distance between the mobile meter reading device 10 and the next fixed meter reading device 20 that needs to perform a meter reading operation.

[0087] F7, if the approach distance is less than the device distance threshold, the mobile meter reading device 10 stops sending the meter reading ciphertext data blocks and the current location information of the mobile device to the data center 30; When the departure distance is less than the device distance threshold, that is, the staff is about to arrive at the corresponding next fixed meter reading device 20 to perform meter reading operations, the mobile meter reading device 10 stops sending meter reading ciphertext data blocks and positioning information to release corresponding computing resources for the next meter reading operation.

[0088] F8, the data center 30 generates corresponding staff movement trajectories according to the current positioning information of all received mobile devices and the corresponding receiving times; The staff movement trajectory is the movement trajectory of the mobile meter reading device 10, which can be regarded as the movement trajectory of the staff when reading the meter of each fixed meter reading device 20; A corresponding movement trajectory can be generated according to the current positioning information of the mobile device and the corresponding receiving time, so as to monitor the work efficiency of the staff.

[0089] F9, manage and evaluate staff based on their movement trajectory and meter reading route information.

[0090] The work status of the staff can be evaluated based on the matching degree between the staff's movement trajectory and the meter reading route information.

[0091] Through the above steps, the water meter reading system can ensure the timeliness of data transmission by automatically sending data when the staff leaves a specific area, optimize resource allocation, and generate movement trajectories by continuously tracking the location information of the staff, thereby monitoring and evaluating the efficiency of the staff and compliance with the meter reading route in real time.

If each of the fixed meter reading devices in the meter reading group positioning information exists in the list of devices to be checked, the staff will perform maintenance work on the fixed meter reading devices.

[0093] Through the above steps, the water meter reading method can timely identify and list hardware anomalies and metering abnormal devices through daily data collection and abnormality monitoring, so as to accurately locate the equipment that needs to be repaired. In addition, the data center can intelligently generate meter reading routes according to the geographical location information of each meter reading device, optimize the meter reading routes of the staff, and check and repair the abnormal fixed meter reading equipment while the staff is reading the meter, so as to ensure the efficiency and systematicness of the meter reading and maintenance work.
