Description

Technical Field

[0001] The present invention relates to the technical field of electric meter communication, and in particular to an electric meter communication method and a system thereof based on WIZE technology. Background Art

[0002] The WIZE module is a wireless communication module based on the Zigbee protocol, and its full name is Wireless Infrastructure for Zigbee based Energy management systems. The WIZE module has the characteristics of low power consumption, long-distance transmission support, high reliability and security.

[0003] like Figure 1 The figure shows the communication mode of the existing WIZE module, where the time period a corresponds to the sleep state, b is the data sending state, c is the sleep state, d is the receiving state, and e is the sleep state. It can be seen that the existing WIZE module does not have the real-time online function, and it only supports opening the downlink receiving window for a certain period of time when there is an uplink.

[0004] Based on the short-time online and long-time sleep functions of the WIZE module, the current WIZE technology is mostly used in the field of gas meters and water meters. This is because gas meters and water meters are both battery-powered and have low-power communication requirements; at the same time, for gas meter and electricity meter users, there is no need to obtain gas meter data and water meter data at any time. Therefore, although the existing WIZE module does not have real-time communication functions, it can well meet the needs of gas meters and water meters.

[0005] Obviously, the existing WIZE module cannot be used in the field of meter reading and communication, because in the field of meter reading and communication, users have a rigid real-time reading requirement for the meter, and the existing WIZE module does not have the real-time online communication function, so it cannot but support the real-time reading function. Summary of the invention

[0006] The present invention aims to solve at least one of the technical problems in the above-mentioned technology to a certain extent. To this end, one object of the present invention is to propose an electric meter communication method based on WIZE technology, which can support real-time meter reading function.

[0009] The WIZE protocol of the WIZE module is updated, and the updated WIZE protocol includes a real-time communication mode, wherein the real-time communication mode is in a receiving state except for a sending state;

[0010] After the WIZE module is connected to the meter, it sends a specific flag to the gateway and changes its communication mode to real-time communication mode;

[0011] The gateway identifies the specific flag bit and modifies the communication mode between itself and the NS server to a real-time communication mode.

[0012] According to an embodiment of the present invention, a meter communication method based on WIZE technology is provided. By adding a real-time communication mode in the WIZE protocol, when the WIZE module recognizes that the meter is connected, it modifies its own communication mode to the real-time communication mode to ensure that the WIZE module can receive messages in real time; at the same time, the WIZE module will also send the flag of the corresponding meter to the gateway, so that the gateway can synchronously modify its communication mode with the NS server to the real-time communication mode to ensure that the gateway can receive messages from the NS server in real time. In this way, a real-time online meter communication link based on WIZE technology is constructed, which can realize real-time meter data reading based on WIZE technology and meet user needs.

[0015] Optionally, the updated WIZE protocol adds a flag corresponding to the electric meter in its device identification flag table, and the updated device identification flag table is pre-stored in the gateway.

[0016] Optionally, after the WIZE module is connected to the electric meter, it sends a specific flag to the gateway, including:

[0017] After the WIZE module is connected to the device, it interacts with the device through synchronization frames to identify the device;

[0018] If the WIZE module identifies the device as an electric meter;

[0019] The flag bit of the corresponding electric meter is enabled, and a pingpong frame with the specific flag bit is sent to the gateway.

[0020] Optionally, the modifying the communication mode between the NS server and the NS server to a real-time communication mode includes:

[0021] The gateway changes its communication mode with the NS server to a real-time communication mode by increasing the frequency of interaction with the NS server.

[0043] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0044] By updating the WIZE protocol, the WIZE module can be modified to real-time communication mode when it recognizes that the access is to an electric meter, ensuring real-time receipt of information; the communication mode between the gateway and the NS server will also be synchronously modified to real-time communication mode, thereby building a real-time online electric meter communication link based on WIZE technology and realizing real-time reading of electric meter data based on WIZE technology.

[0045] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0046] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0047] The existing WIZE technology communication mode specified by the WIZE protocol is as follows: Figure 1 As shown in the figure, it is in a dormant state in most of the time to reduce power consumption, and only supports opening a downlink receiving window for a certain period of time when there is an uplink. Therefore, the system end composed of the existing WIZE module configured on the meter will not be able to operate the meter in real time, nor can it send data to the gateway in real time, that is, it cannot realize real-time meter reading.

[0048] Figure 2 A flow chart of an electric meter communication method based on WIZE technology provided in an embodiment of the present invention; Figure 3 Schematic diagram of the real-time communication mode in the updated WIZE protocol in an embodiment of the present invention.

[0049] See also Figure 2 , an embodiment of the present invention provides an electric meter communication method based on WIZE technology, which at least includes the following steps S1 to S3.

[0050] In step S1, the WIZE protocol of the WIZE module is updated, and the updated WIZE protocol includes a real-time communication mode, wherein the real-time communication mode is in a receiving state except for a sending state.

[0051] like Figure 3 As shown, the real-time communication mode refers to the state except the transmitting state (corresponding to Figure 3 Except for the black time period, the rest of the time is in the normal receiving state.

[0052] In some specific implementations, the operating rules of the real-time communication mode are:

[0053] After the WIZE module enters the real-time communication mode, the control removes all sleep functions and its MCU is always in the awakened state; at the same time, after the data frame is sent, the control enables its PA (power amplifier of the RF front end) to be in the receiving mode; in addition, if the control receives the WIZE data frame sent by the gateway during the time other than sending the data frame, it will immediately forward it to its application layer for processing.

[0054] It can be seen that the WIZE module of this embodiment is based on the updated WIZE protocol, and the newly added configuration is especially applied to the real-time communication mode in the field of electric meters, so that the WIZE module on the electric meter that communicates with the outside world can be online in real time, and can receive and process messages from the system at any time, and can also provide instant feedback.

[0055] In step S2, after the WIZE module is connected to the electric meter, it sends a specific flag to the gateway and modifies its own communication mode to the real-time communication mode.

[0056] In this embodiment, the real-time communication mode newly configured in the updated WIZE protocol will only be entered when the WIZE module confirms that the currently connected device is an electric meter. That is, the newly added real-time communication mode is dedicated to electric meters. Therefore, after the WIZE module accesses the device, it is necessary to identify the currently connected device to confirm whether it is necessary to modify the communication mode.

[0057] In some specific implementations, the process of the WIZE module identifying a device includes:

[0058] S2a: The updated WIZE protocol adds a specific flag corresponding to the electric meter in its device identification flag table, obtains an updated device identification flag table, and the updated device identification flag table is pre-stored in the gateway;

[0059] Here, the updated identification flag table contains at least a specific flag corresponding to the electricity meter, such as the flag corresponding to the device "electricity meter" is a specific value "2". Optionally, it also includes flags corresponding to water meters and gas meters, such as the flag values ​​0 / 1 correspond to water / gas meters respectively. It can be understood that the gateway and the WIZE module jointly maintain an identification flag table for identifying devices, which is used to identify what device WIZE is connected to, whether it is a water meter, a gas meter or an electricity meter.

[0060] S2b: After the WIZE module is connected to the device, it identifies the device by exchanging synchronization frames with the device;

[0061] Here, the WIZE module polls the serial port baud rate, first sends a general ACK frame to the device, and waits for hundreds of milliseconds. If the device's response frame is not received, the module switches the baud rate until the WIZE module receives the device's general response frame; then the WIZE module obtains the device's version number, device time, device type and other information through the serial port, and passes the WIZE module's information to the device.

[0062] S2c: If the WIZE module recognizes that the currently connected device is a gas meter or water meter, the default communication mode is used;

[0063] S2d: If the WIZE module recognizes that the currently connected device is an electric meter, it executes:

[0064] (1) Enable the specific flag bit of the corresponding electric meter, and then send a pingpong frame with the specific flag bit to the gateway. The purpose of this is to inform the gateway that the device connected this time is an electric meter; and the gateway is informed by a specific network access frame, that is, a pingpong frame, one is to tell the gateway that a new device is online, and the other is to upload the type and model of the device to the gateway and then transmit it to the system.

[0065] As a preferred example, the WIZE module can enable the L6NetwId flag to a specific value, such as "2"; and then send a pingpong frame carrying "L6NetwId flag is 2" to the gateway, thereby informing the gateway that the current WIZE module is connected to an electricity meter.

[0066] (2) The WIZE module changes its communication mode to real-time communication mode. This can also be understood as controlling the execution of the operating rules of the above real-time communication mode. The purpose of this is to ensure that the WIZE module is online in real time and can receive and process messages from the system at any time.

[0067] In step S3, the gateway identifies the specific flag bit and modifies the communication mode between itself and the NS server to a real-time communication mode.

[0068] Corresponding to the above specific implementation, after receiving the specific flag, the gateway will parse it, that is, confirm the corresponding device according to the preset device identification flag table, and recognize that the WIZE module is connected to the electric meter.

[0069] In this embodiment, after the gateway confirms through the specific flag bit that the WIZE module is currently connected to the electricity meter, the interactive communication mode between the gateway and the NS server is modified to the real-time communication mode.

[0070] In some specific implementations, since the communication connection between the gateway and the NS server is based on technologies such as 4G, the communication mode between itself and the NS server is modified to a real-time communication mode. The gateway only needs to increase the interaction frequency with the NS server, such as changing the original interaction time of 15 minutes to real-time, to change the original communication mode between the gateway and the NS server from once every 15 minutes to a real-time communication mode.

[0071] As can be seen from the above, this embodiment updates the WIZE protocol of the WIZE module so that the WIZE module connected to the meter can be online in real time, so as to have the function of receiving meter reading instructions and sending meter reading data in real time; accordingly, the gateway and the NS server will also maintain real-time communication interaction. In this way, a real-time communication interaction link between the NS server-gateway-WIZE module-meter based on the WIZE technology is realized, and the user can remotely operate the meter at any time and get feedback in time, thereby realizing real-time meter reading based on the WIZE technology to meet the needs of users.

[0072] Figure 4 A complete flow chart of an electric meter communication method based on WIZE technology provided in an embodiment of the present invention.

[0073] See also Figure 4 The embodiment of the present invention is based on Figure 2 The embodiment is further extended, and the complete process of the electric meter communication method based on WIZE technology includes: Figure 2 The steps S1-S3 of the embodiment further include the following steps S4-S8.

[0074] In step S4, the user controls the NS server to send a data frame instruction to the gateway through the POC, and the data frame instruction carries the meter reading number.

[0075] Here, the POC refers to the mediator between the system and the NS server, which has a visual interface and is used to display information from the NS server or information to be sent to the NS server in the form of a visual interface. Users can use the system to operate the POC to view information from the NS server or send information to the NS server. That is, the POC provides users with a visual control function for meter reading services.

[0076] Here, the data frame instruction refers to an instruction for reading specific meter data of a specific meter, such as an instruction for reading a data item of total power of a certain meter.

[0077] Here, the data frame instruction sent by the POC to the NS server is a downlink data frame, carrying the meter number to be read, that is, the meter reading number; and the NS server has the function of remembering which gateway the uplink data also carrying the meter reading number is sent from; therefore, after the NS server receives the downlink data frame instruction, it can confirm the corresponding gateway based on the meter reading number it carries; in particular, since the NS server and the gateway are in real-time communication mode, the NS server will immediately send the data frame instruction to the confirmed gateway after receiving the data frame instruction.

[0078] In step S5, after receiving the data frame instruction sent by the NS server, the gateway immediately forwards the data frame instruction to the WIZE module.

[0079] Here, after receiving the data frame instruction, the gateway will immediately send the data frame instruction to the WIZE module of the corresponding meter according to the meter reading number it carries. In particular, since the WIZE module of this embodiment is already in real-time online mode, it can immediately receive the data frame instruction sent by the gateway.

[0080] In step S6, the WIZE module forwards the data frame instruction to the corresponding electricity meter.

[0081] Here, based on the real-time online status of the WIZE module, the forwarding behavior of the WIZE module is also executed immediately, thereby ensuring that the electric meter can immediately receive the data frame instruction sent by the gateway.

[0082] Here, the electric meter will process the received data frame instruction to obtain a corresponding reply frame. For example, a data frame instruction corresponding to reading the total power of the electric meter will generate a reply frame carrying the current total power of the electric meter.

[0083] In step S7, the electric meter sends a reply frame corresponding to the data frame instruction to the gateway through the WIZE module.

[0084] Here, also based on the real-time online status of the WIZE module, the WIZE module will immediately send the reply frame after receiving it, so as to ensure that the system end user receives the meter reading data in real time.

[0085] In step S8, the gateway immediately forwards the received reply frame to the NS server.

[0086] Here, the gateway will immediately receive the reply frame sent by the WIZE module, and based on the real-time communication status maintained between itself and the NS server, it can immediately send the reply frame to the NS server; and the NS server will also immediately forward it to the POC interface for system end users to view.

[0087] In some specific implementations, if there are multiple gateways in the system, multiple gateways will receive the reply frame; accordingly, the NS server will also receive the reply frames sent by multiple gateways at the same time. Here, the NS server will take the reply frame with the best signal strength among the uplink reply frames as the final reception result.

[0088] In the electric meter communication method based on WIZE technology of this embodiment, the WIZE module works in real-time communication mode and can receive messages from the gateway (sent by the system end) at any time; the NS server and the gateway also work in real-time communication mode and can instantly transmit the messages sent by the user through the system end to the WIZE module at any time. Therefore, the user can remotely operate the electric meter at any time and get real-time feedback, thereby meeting the user's real-time meter reading needs.

[0089] See also Figure 5 , Figure 5 A schematic diagram of the framework structure of an electric meter communication system based on WIZE technology provided by an embodiment of the present invention.

[0095] In some specific embodiments, Figure 5 As shown, the electric meter communication system further includes a POC 5; the POC is connected to the NS server;

[0096] The POC is configured to display messages from the NS server and information to be sent to the NS server in the form of a visual interface.

[0097] The electric meter communication system based on WIZE technology in this embodiment updates the WIZE protocol in the WIZE module. When it is identified that the access is to an electric meter, it works in real-time communication mode, so that the WIZE module has a real-time receiving function; at the same time, the WIZE module will also send a specific flag bit of the corresponding electric meter to the gateway, so that the gateway and the NS server also work in real-time communication mode, so that the gateway has a real-time receiving function. Thus, a real-time online electric meter communication system based on WIZE technology is constructed, which can realize real-time reading of electric meter data based on WIZE technology to meet user needs.

[0098] In summary, the electric meter communication method and system based on WIZE technology provided by the present invention, by adding a real-time communication mode in the WIZE protocol, when the WIZE module recognizes that the access is to an electric meter, it will work in the real-time communication mode to ensure that messages from the gateway (sent by the system end) can be received at any time; at the same time, the NS server and the gateway will also be controlled to work in the real-time communication mode to ensure that the messages sent by the user through the system end can be transmitted to the WIZE module in real time at any time. Therefore, real-time meter reading based on WIZE technology can be realized, and the user can remotely operate the electric meter at any time and get feedback in real time; thereby meeting the user's real-time meter reading needs.
