[0058] In the following, in conjunction with the accompanying drawings, a meter reading method, device, equipment and medium based on wireless Internet of Things communication technology provided by the embodiment of the present application are described in detail through specific embodiments and their application scenarios.

[0059] Embodiment 1

[0060] Figure 1 It is a flow chart of a meter reading method based on wireless Internet of Things communication technology provided in Example 1 of the present application.

[0061] like Figure 1 As shown, the specific steps include:

[0062] S101, determining the layout location of each smart water meter;

[0063] The application scenario of this solution can be the scenario of remote wireless meter reading of smart water meters in buildings.

[0064] Based on the above scenario, it can be understood that the executor of this scenario can be a server for managing the connection status of the smart water meter, such as a computer or software component that provides services in a network environment, etc., and no excessive limitations are made here.

[0065] Smart water meters are a new type of water meter that measures water consumption, transmits water consumption data, and settles transactions. The functions of smart water meters include recording and electronically displaying water consumption, controlling water consumption according to agreements, and automatically calculating water charges for tiered water prices. They also have the function of storing water consumption data.

[0066] The way to determine the layout position of each smart water meter can be to obtain the layout record of the water meters in the building, and extract the number information of each smart water meter and the layout position of each smart water meter in the building from the layout record.

[0067] S102, connecting the smart water meter to a gateway to establish a wireless network;

[0068] A gateway is a network interconnection device that realizes network interconnection above the network layer. It is only used to interconnect two networks with different high-level protocols. A gateway can be used for both wide area network interconnection and local area network interconnection.

[0069] Wireless network refers to a network that can interconnect various communication devices without wiring. Wireless network technology covers a wide range, including global voice and data networks that allow users to establish long-distance wireless connections, as well as infrared and radio frequency technologies that are optimized for short-distance wireless connections. Wireless networks are generally combined with telecommunications networks, and no cables are required to connect nodes to each other.

[0070] The way to build a wireless network is to connect all the smart water meters that need to be managed to the gateway in a building unit, and then connect the gateway to the management platform, so that the management platform can manage the smart water meters connected to the gateway by controlling the gateway.

[0071] S103, identifying the connection status of each smart water meter, taking the smart water meter with disconnected connection as the target smart water meter, and reading the layout position of the target smart water meter;

[0072] The method for identifying the connection status of each smart water meter is that the gateway sends a test signal to each smart water meter connected to it. After receiving the test signal, the smart water meter feeds back confirmation reception information to the gateway. The gateway counts the confirmation reception information and confirms the smart water meters that can receive the confirmation reception information as being able to connect, and confirms the smart water meters that cannot receive the confirmation reception information as having a disconnected connection.

[0073] The method for reading the location of the target smart water meter is to confirm that the smart water meter that cannot receive the confirmation reception information is disconnected, and the smart water meter serves as the target smart water meter, and reads the location of the target smart water meter from the pre-configured smart water meter information.

[0074] S104, determining at least one uninterruptedly connected smart water meter as a relay node according to the layout location of the target smart water meter, and connecting the target smart water meter to the relay node;

[0075] The relay node may not only be able to report meter reading information to the gateway, but also be able to receive meter reading information of a target smart water meter and forward the meter reading information to a smart water meter of the gateway that is not disconnected from the gateway.

[0076] The method of connecting the target smart water meter with the relay node can be to determine the smart water meter closest to the target smart water meter according to the layout location of the target smart water meter, use the smart water meter closest to the target smart water meter as the relay node, and establish a communication channel between the relay node and the target smart water meter according to the IP addresses of the relay node and the target smart water meter, thereby connecting the target smart water meter to the relay node.

[0077] S105, obtaining meter reading information of the target smart water meter through the relay node;

[0078] The method for obtaining the meter reading information of the target smart water meter through the relay node can be that the relay node sends a meter reading information acquisition instruction to the target smart water meter, and the target smart water meter counts the collected water use data according to the water use time, calculates the total water use amount and the corresponding water fee amount during the water use period, and sends the total water fee amount and the number information of the target smart water meter as the meter reading information to the relay node.

[0079] S106: Transmit the meter reading information of the target smart water meter to the management platform through the gateway.

[0080] The management platform can be a platform for uniformly managing and recording the connection status of each smart water meter and the collected meter reading data. Through the management platform, users can uniformly read the smart water meters, store and view the meter reading information, and monitor and manage the connection status of the smart water meters.

[0081] The method of transmitting the meter reading information to the management platform through the gateway can be that each smart water meter sends the meter reading information collected by itself and the meter reading information received from the target smart water meter to the gateway, and after receiving the information, the gateway arranges the meter reading information according to the arrangement position sequence or number information sequence of each smart water meter, for example, arranges the corresponding meter reading information in sequence according to the house number of the user recorded by the smart water meter, etc. The gateway sends the arranged meter reading information to the management platform.

[0082] Based on the above solution, optionally, the smart water meter is connected to a gateway to form a wireless network, including:

[0083] Determine the gateway installation location based on the layout of each smart water meter. If all smart water meters are concentrated in the same meter room, install the gateway in the meter room. If all smart water meters are distributed in meter rooms on each floor of the same building, install the gateway on the roof.

[0084] Entering the installation location and water meter number of the smart water meter into the gateway;

[0085] The gateway is connected to a management platform to form a wireless network.

[0086] The water meter number may be a number used to represent the unique identification information of the smart water meter, or may be an IP address of the smart water meter.

[0087] The method of determining the installation location of the gateway according to the layout location of each smart water meter can be to count the layout locations of each smart water meter. When the smart water meters are all distributed in the same meter room in the building, the gateway can be set in the meter room or on the outer wall of the meter room; when the smart water meters are distributed in the meter room on each floor of the building, or the smart water meters are distributed near the rooms of each household, the gateway can be set in the middle floor or the roof layer of the building, where the roof layer usually refers to the distance between the upper top surface and the lower top surface (ground) inside the building, which is usually not less than 4 meters and the area is not less than 10 square meters. Or it indicates the internal area of ​​the building with the top made of light-transmitting materials, generally referring to the roof part where people can go.

[0088] The way to enter the location of the smart water meter and the water meter number into the gateway is that the staff can log in to the local management page of the gateway through WIFI and enter the location of the smart water meter and the water meter number into the corresponding configuration column of the local management page.

[0089] The gateway can be connected to the management platform by the management platform establishing a communication channel through the MQTT (Message Queuing Telemetry Transport) domain name and port equal to the gateway. Based on the connection of the communication channel, the gateway and the management platform can communicate through the MQTT protocol.

[0090] The advantage of this solution is that by setting up a gateway in a building, full coverage of the smart water meters in the building can be achieved, and a wireless network can be established to facilitate the management platform to uniformly monitor and manage the smart water meters in multiple buildings.

[0091] Based on the above solution, optionally, after identifying the connection status of each smart water meter and taking the smart water meter with disconnected connection as the target smart water meter, the method further includes:

[0092] Reconnecting the target smart water meter to the gateway after a preset period;

[0093] If the gateway connection fails and the number of failures reaches a set threshold, the target smart water meter is adjusted to a low power consumption mode.

[0094] The preset period may be a pre-set time interval for reconnecting the target smart water meter whose connection is interrupted. For example, if the preset period is 24 hours, then 24 hours after determining that the target smart water meter connection is interrupted, the gateway resends a connection request to the target smart water meter.

[0095] The threshold value may be the minimum number of gateway connection failures for determining that the target smart water meter cannot be reconnected. For example, if the threshold value is set to 3 times, then after the gateway fails to reconnect to the target smart water meter 3 times, the target smart water meter will no longer be reconnected.

[0096] The method for connecting the target smart water meter to the gateway may be that after a preset period is reached, the gateway sends a connection request to the IP address of the target smart water meter. If a successful connection feedback from the target smart water meter is obtained, it is determined that the target smart water meter has restored the connection, and the data transmission with the target smart water meter is deleted in the relay node connected to the target smart water meter, so that the target smart water meter directly transmits the meter reading information to the gateway; if a successful connection feedback from the target smart water meter is not obtained, it is determined that the gateway connection has failed.

[0097] The target smart water meter can be adjusted to a low power consumption mode by accumulating the number of gateway connection failures. When the number reaches a set threshold, the next reconnection to the target smart water meter is stopped, and the mode of the target smart water meter is adjusted to a low power consumption mode, thereby preventing the target smart water meter from actively sending meter reading information to the gateway, and putting the target smart water meter into sleep mode until awakened by a wake-up command from the gateway.

[0098] The benefit of this setting of the scheme is that it can make the target smart water meter that has failed to connect multiple times enter a low power consumption mode, thereby reducing energy consumption, extending the battery life of the target smart water meter and reducing maintenance costs, and improving the stability and reliability of the system.

[0099] This solution provides a program code for determining the relay node and connecting the target smart water meter to the relay node for reference:

[0100]

[0101]

[0102] In the embodiment of the present application, the layout location of each smart water meter is determined; the smart water meter is connected to the gateway to form a wireless network; the connection status of each smart water meter is identified, the smart water meter with interrupted connection is used as the target smart water meter, and the layout location of the target smart water meter is read; at least one smart water meter with uninterrupted connection is determined as a relay node according to the layout location of the target smart water meter, and the target smart water meter is connected to the relay node; the meter reading information of the target smart water meter is obtained through the relay node; the meter reading information of the target smart water meter is transmitted to the management platform through the gateway. Through the above-mentioned meter reading method based on wireless Internet of Things communication technology, the smart water meter can be used as a relay node to connect the smart water meter with poor network environment, so as to achieve the purpose of self-service repair of the smart water meter when it is disconnected from the network, realize the high reliability of the smart water meter, and make the meter reading data more complete.

[0103] Embodiment 2

[0104] Figure 2 This is a flow chart of a meter reading method based on wireless Internet of Things communication technology provided in Example 2 of the present application. This solution makes a better improvement on the above-mentioned embodiment, and the specific improvement is: according to the layout location of the target smart water meter, at least one smart water meter with uninterrupted connection is determined as a relay node, including: taking the smart water meters with uninterrupted connection within a preset range of the layout location of the target smart water meter as candidate nodes; identifying the network status of the candidate nodes, and selecting the candidate node with the best network status as the relay node.

[0105] like Figure 2 As shown, specifically including the following:

[0106] S201, determining the layout location of each smart water meter;

[0107] S202, connecting the smart water meter to a gateway to establish a wireless network;

[0108] S203, identifying the connection status of each smart water meter, taking the smart water meter with disconnected connection as the target smart water meter, and reading the layout position of the target smart water meter;

[0109] S204: taking the uninterruptedly connected smart water meters within the preset range of the target smart water meter deployment location as candidate nodes;

[0110] The preset range may be the maximum search range of the target smart water meter for the relay node, which is determined in advance by the staff based on the communication range of the relay node.

[0111] The method of using smart water meters as candidate nodes is to determine the location of the target smart water meter, set the search range with the location as the center and the preset range as the radius, obtain all smart water meters with locations within the search range, and extract the smart water meters that have not been disconnected from the gateway as candidate nodes.

[0112] S205, identifying the network status of the candidate nodes, selecting the candidate node with the best network status as a relay node, and connecting the target smart water meter to the relay node;

[0113] The network status may include parameters such as the network fluctuation of the candidate node, information transmission rate, and information transmission accuracy. A candidate node with a better network status has a better information transmission capability.

[0114] The method of selecting a relay node may be to detect the network status of each candidate node, extract parameters with the smallest network fluctuation, the fastest information cycle rate, and the highest information transmission accuracy from the detection results, and then select the corresponding candidate node as a relay node.

[0115] S206, obtaining meter reading information of the target smart water meter through the relay node;

[0116] S207: Transmit the meter reading information of the target smart water meter to the management platform through the gateway.

[0117] The advantage of this setting is that by screening the network status of candidate nodes, within the range that can be connected to the target smart water meter, the candidate node with the best connection quality can be selected as the relay node to ensure the accuracy of the meter reading information subsequently sent to the management platform.

[0118] Embodiment 3

[0119] Figure 3 It is a flow chart of a meter reading method based on wireless Internet of Things communication technology provided in the third embodiment of the present application. This solution makes a better improvement on the above embodiment, and the specific improvement is: obtaining the meter reading information of the target smart water meter through the relay node, including: the management platform sends a meter reading instruction to each smart water meter through the gateway; after receiving the meter reading instruction, the relay node sends the meter reading instruction to the target smart water meter; accordingly, the meter reading information of each smart water meter is transmitted to the management platform through the gateway, and also includes: the target smart water meter sends the meter reading information to the relay node connected to it; the relay node sends its own meter reading information and the meter reading information of the target smart water meter to the gateway respectively.

[0120] like Figure 3 As shown, specifically including the following:

[0121] S301, determining the layout location of each smart water meter;

[0122] S302, connecting the smart water meter to a gateway to establish a wireless network;

[0123] S303, identifying the connection status of each smart water meter, taking the smart water meter with disconnected connection as the target smart water meter, and reading the layout position of the target smart water meter;

[0124] S304, determining at least one uninterruptedly connected smart water meter as a relay node according to the layout location of the target smart water meter, and connecting the target smart water meter to the relay node;

[0125] S305, the management platform sends meter reading instructions to each smart water meter through the gateway;

[0126] The meter reading instruction may be an instruction issued when the management platform needs to obtain the meter reading information of the smart water meter.

[0127] The management platform sends meter reading instructions to each smart water meter through the gateway. The staff can issue meter reading instructions to the corresponding gateway through the meter reading information acquisition option of the management platform, and the gateway forwards the meter reading instruction to the corresponding smart water meter. It is understandable that the staff can also set the meter reading time through the management platform. When the meter reading time is reached, the management platform can autonomously trigger the meter reading instruction sending task.

[0128] S306. After receiving the meter reading instruction, the relay node sends the meter reading instruction to the target smart water meter;

[0129] The method of sending the meter reading instruction to the target smart water meter is that after receiving the meter reading instruction from the gateway, the smart water meter detects whether it is connected to the target smart water meter, and if so, forwards the meter reading instruction to the target smart water meter.

[0130] S307, the target smart water meter sends the meter reading information to the relay node connected thereto;

[0131] The target smart water meter sends meter reading information by collating and counting the collected water usage data after receiving the meter reading instruction from the relay node, obtaining meter reading information, and sending the meter reading information to the relay node connected thereto.

[0132] S308. The relay node sends its own meter reading information and the meter reading information of the target smart water meter to the gateway respectively.

[0133] The relay node sends the meter reading information to the gateway in such a way that, upon receiving the meter reading instruction, the relay node forwards the instruction to the target smart water meter, and at the same time, organizes and counts the water consumption data collected by itself, obtains its own meter reading information, and sends the meter reading information to the gateway. After the relay node receives the meter reading information sent by the target smart water meter, the meter reading information of the target smart water meter is also sent to the gateway. The gateway organizes all the received meter reading information and uniformly uploads it to the management platform.

[0134] The benefit of this arrangement of the scheme is that the meter reading information can be forwarded to the target smart water meter that is disconnected from the gateway through the relay node, so as to achieve the purpose of self-service repair of the smart water meter when it is offline, thereby improving the reliability of the smart water meter.

This solution makes a better improvement on the above embodiment, and the specific improvement is: after the meter reading information of each smart water meter is transmitted to the management platform through the gateway, the method also includes: verifying the meter reading information received by the management platform, and counting whether it contains the uploaded data of all smart water meters; when it is detected that there is a missing uploaded data of the smart water meter, the missing data is supplemented; if the supplementary reading fails, the smart water meter with missing uploaded data is used as the target smart water meter.

[0137] like Figure 4 As shown, specifically including the following:

[0142] S405, obtaining meter reading information of the target smart water meter through the relay node;

[0143] S406, transmitting the meter reading information of the target smart water meter to the management platform through the gateway;

[0144] S407, verifying the meter reading information received by the management platform, and counting whether it contains the uploaded data of all smart water meters;

[0145] The method for verifying the meter reading information received by the management platform is to extract the number information of the smart water meter in each meter reading information after receiving the meter reading information uploaded by the gateway, and retrieve the basic information of the smart water meter pre-configured by the staff on the management platform, compare the number information with the basic information, and identify whether the number information contains all the smart water meter numbers in the basic information. If so, the meter reading information contains the uploaded data of all smart water meters; if not, the uploaded data of the smart water meters is missing in the meter reading information.

[0146] S408, when it is detected that there is missing data uploaded by the smart water meter, the missing data is copied;

[0147] The method for supplementing the missing data is to obtain the number information of the smart water meter corresponding to the missing data when it is detected that the data uploaded by the smart water meter is missing, send a meter reading instruction to the smart water meter with missing data according to the number information, and receive feedback data from the smart water meter.

[0148] S409: If the supplementary reading fails, the smart water meter with missing uploaded data is used as the target smart water meter.

[0149] The method of taking the smart water meter with missing uploaded data as the target smart water meter is that after sending the meter reading instruction to the smart water meter with missing data, if no feedback information from the smart water meter is received, it is determined that the supplementary reading has failed, and the smart water meter with missing data is taken as the target smart water meter, so that its meter reading information can be subsequently uploaded to the management platform through the relay node.

[0150] The advantage of this arrangement of the scheme is that after the management platform receives the exceeding-standard information, the integrity of the meter reading information can be verified, and the situation of disconnection of the smart water meter can be identified in time to avoid omissions in the meter reading information and unnecessary losses.

[0151] On the basis of the above scheme, optional supplementary copying of missing data is available, including:

[0152] When it is detected that there is a missing data uploaded by a smart water meter, the first round of supplementary copying is performed on the smart water meter with missing uploaded data;

[0153] If there are smart water meters that fail to make up the reading in the first round, the interval between the current time and the start time of the next cycle is calculated, half of the interval is taken, and a second round of make up the reading is performed on the smart water meters that failed to make up the reading in the first round;

[0154] Correspondingly, if the supplementary reading fails, the smart water meter with missing uploaded data will be used as the target smart water meter, including:

[0155] If there are still smart water meters that fail to read in the second round, they will be used as target smart water meters.

[0156] The first round of supplementary reading may be to supplement the smart water meters with missing data immediately after detecting that the uploaded data of the smart water meters are missing.

[0157] The second round of supplementary reading can be performed in such a way that, in the first round of supplementary reading, if there is a smart water meter that fails to be supplemented, then a meter reading instruction is sent to the smart water meter that fails to be supplemented again at the interval between the current time and half of the start of the next cycle, and a second round of supplementary reading is performed. For example, the smart water meter is set to be read at 24:00 every day, and missing data is found after the meter reading, and the first round of supplementary reading is performed. The time of the smart water meter that fails to be supplemented is 00:06, then the time interval between the current time and the start of the next cycle is 23 hours and 54 minutes, and half of the interval is 11 hours and 57 minutes, so the time of the second round of supplementary reading is 12:03.

[0158] The method for determining the target smart water meter is that when there are still smart water meters that failed to read in the second round of reading, the smart water meter can be used as the target smart water meter, and in the next meter reading process, it can be connected to the relay node to report the meter reading information through the relay node.

[0159] The advantage of this arrangement of the scheme is that when it is found that the meter reading information is missing, the missing smart water meter can be re-read twice, which is conducive to avoiding the problem of loss of meter reading data during transmission. The smart water meter that failed to re-read is connected to the relay node, and the problem of smart water meter connection interruption can be repaired in time to avoid causing greater losses.
