Description

Technical Field

[0001] The present invention relates to the technical field of equipment management, and in particular to a communication management method, device, equipment, medium and product for an intelligent meter. Background Art

[0002] The Highway Addressable Remote Transducer (HART) protocol uses frequency shift keying technology to allow digital and analog signals to be transmitted simultaneously without interfering with each other, making it a standard communication protocol widely used in smart instrument applications. In the actual transmission process, the existing HART protocol parses the required parameters into several commands based on the parameter information defined in the smart instrument device description file DD, and completes the data communication with a smart instrument through a question-and-answer mechanism, that is, the number of communication interactions required is the number of required parameters.

[0003] However, as smart meters become increasingly complex, a single smart meter may contain hundreds of parameters, so a complete data reading may require at least hundreds of communication interactions. On the other hand, for the sake of data security and the correctness of the interaction logic, the existing communication management solutions for smart meters do not support concurrent communication between a single communication device and multiple smart meters connected to it, that is, after the management device controls a communication device to communicate data with a smart meter connected to the communication device, it cannot communicate with other smart meters under the communication device before the data communication of the meter is completed or all communication interactions defined by the DD are completed.

[0004] This results in problems such as low communication efficiency, long response time, poor availability, and untimely data updates if the management device needs to parse or process the smart meter communication data, or perform user interaction or logical processing on the smart meter communication data according to the methods in the DD, which affects the user experience. Summary of the invention

[0028] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] It should be noted that due to the increasing complexity of smart meters, a single smart meter may contain hundreds of commands, so a complete data reading may require at least hundreds of communication interactions; in addition, for the sake of data security and the correctness of the interaction logic, the existing communication management solutions for smart meters do not support concurrent communication between a single communication device and multiple smart meters connected to it, so that especially when it is necessary to parse or process the communication data of the smart meter, or to perform user interaction operations or logical processing on the communication data of the smart meter according to the methods in the DD, the existing communication management solutions for smart meters have problems such as low communication efficiency, long response time, poor availability and untimely data updates.

[0031] Based on this, an embodiment of the present invention provides a communication management method for a smart meter, which is applied to an electronic device, wherein the electronic device is connected to at least one communication device, each communication device includes at least one external interface, and at least one smart meter establishes a communication connection with the electronic device through an external interface of the communication device.

[0032] It should be noted that the communication connections established between the same communication device and different smart meters are independent of each other to ensure the correctness of communication. The communication between the communication device and the smart meter complies with the HART protocol.

[0033] Figure 1 A flow chart of a communication management method for a smart meter provided in an embodiment of the present invention. The embodiment of the present invention can be applied to scenarios where electronic devices communicate with smart meters in the fields of industrial automation, energy management, environmental monitoring, etc. The method can be executed by a communication management device for a smart meter, which can be implemented in the form of software and / or hardware. Optionally, it can be implemented by an electronic device, which is preferably a mobile terminal, a desktop computer, a laptop computer, a server, etc.

[0034] like Figure 1 As shown, the communication management method of the smart meter provided in the embodiment of the present invention may specifically include:

[0035] S101, acquiring at least one instrument communication task generated after satisfying a task initiation condition, and determining a first smart instrument corresponding to each instrument communication task.

[0036] Among them, the instrument communication task can be understood as the task of data exchange and communication between electronic equipment (such as monitoring equipment, control equipment, etc.) and intelligent instrument equipment, such as reading the real-time data of the intelligent instrument, setting the parameters of the intelligent instrument, controlling the output of the intelligent instrument, etc. The first intelligent instrument can be understood as an intelligent instrument corresponding to each instrument communication task one by one, that is, an intelligent instrument that needs to be used under the current instrument communication task. The intelligent instrument can include temperature meters, pressure meters, flow meters, analyzers, etc.

[0037] In this embodiment, when the electronic device obtains an operation task for a smart meter and performs a corresponding operation on the smart meter according to the operation task, such as starting inspection and parameter reading and writing of the whole plant (or multiple) smart meters, it is considered that the task initiation condition is met, and an instrument communication task corresponding to the executed operation is generated. After the generated instrument communication tasks are obtained in real time, the first smart meter corresponding to each instrument communication task is determined.

[0038] Exemplarily, the electronic device may obtain the operation task for the smart meter by receiving one or more operation tasks determined by the user through a drop-down list, a search box, an editable text box, or a file upload on a display interface; it may also be an operation task preset in the electronic device to be started at a scheduled time or performed in real time, etc. The operation task may be reading parameters, status monitoring, or scheduled communication, etc.

[0039] S102: Determine, according to the pre-constructed tree-like communication information, the first communication devices to which the first smart meters are respectively connected.

[0040] In this embodiment, a tree-like communication structure is constructed in advance according to the communication devices and smart meters that need to be serialized through configuration, system scanning and other operations. For example, the tree-like communication information can use the electronic device as the root node, each communication device as the parent node, and each smart meter as the child node. By analyzing the pre-constructed tree-like communication information, the communication path of each first smart meter can be determined, and the first communication device connected to each first smart meter can be determined according to the node information and the communication path. The first communication device can be a HART cat, a controller, a multiplexer, etc.

[0041] S103: When the number of first smart meters connected to the first communication device is 1, directly send an associated meter communication task to the connected first smart meter through the first communication device.

[0042] In this embodiment, for the case where the number of first smart meters connected to the first communication device is 1, that is, no other first smart meters are connected to the first communication device, the communication state of the first communication device is always idle, and the associated meter communication task is directly sent to the connected first smart meter through the first communication device. It can be understood that in the case, the method of sending the associated meter communication task to the connected first smart meter through the first communication device can be parallel communication, that is, sending the associated meter communication task to the corresponding first smart meter through each first communication device in parallel.

[0043] The method of sending the associated instrument communication task to the connected first smart meter through the first communication device can be to use a task parsing thread to decompose different instrument communication tasks into corresponding communication commands according to the smart meter device description file, encapsulate the communication commands according to the set communication protocol (i.e., the open communication HART protocol for highway addressable remote sensors) to form a communication command data packet, and send the communication command data packet to different first smart meters through the first communication device.

[0044] S104: When the number of first smart meters connected to the first communication device is greater than 1, the first communication device polls and sends associated meter communication tasks to each of the first smart meters connected according to a set task scheduling method.

[0045] In this embodiment, when the number of first smart meters connected to the first communication device is greater than 1, that is, multiple first smart meters need to send corresponding meter communication tasks to the same first communication device. At this time, according to the set task scheduling method, each first communication device polls and sends the associated meter communication tasks to each connected first smart meter.

[0046] Exemplarily, the method of polling and sending associated instrument communication tasks to each connected first smart meter according to the set task scheduling method may be that, for the instrument communication tasks corresponding to the first smart meters connected to the same first communication device, the instrument communication tasks are prioritized in real time according to a preset sorting scheme such as the urgency, importance, and / or arrival order of the instrument communication tasks, and they are decomposed into corresponding communication commands in the corresponding data parsing threads of different smart meters in sequence, and each communication command is encapsulated according to the set communication protocol (HART protocol) to form each communication command data packet, and each communication command data packet is sent to the associated first smart meter through the first communication device according to the sorting.

[0047] It should be noted that when the first communication device has sent a communication command data packet and has not received a return data packet from the smart meter, it is considered that the first communication device is in a busy state and cannot send other communication command data packets at this time. When the first communication device is not waiting to receive a return data packet returned by the smart meter, such as when the first communication device has not started to send a communication command data packet, or when the first communication device has sent a return data packet to the electronic device and has not sent a new communication command data packet, it is considered that the first communication device is in an idle state, and the communication command data packet ranked first at this time can be sent to the corresponding first smart meter through the first communication device. The first smart meter can respond to a specific command in the communication command data packet according to a preset rule, and feedback an information data packet to the first communication device, and the information data packet can include the required data or information returned according to the communication command data packet, such as diagnostic data, calibration data, troubleshooting information, and transmitter readings.

[0048] A communication management method for a smart meter provided in an embodiment of the present invention obtains at least one meter communication task generated after a task initiation condition is met, and determines the first smart meter corresponding to each meter communication task; determines the first communication devices connected to each first smart meter according to pre-constructed tree communication information; in the case where the number of first smart meters connected to the first communication device is 1, directly sends the associated meter communication tasks to the connected first smart meters through the first communication device; in the case where the number of first smart meters connected to the first communication device is greater than 1, polls and sends the associated meter communication tasks to each connected first smart meter according to a set task scheduling method. The method determines the number of first smart meters connected to the first communication device. When the number of connected first smart meters is greater than 1, the method polls and sends associated meter communication tasks to the connected first smart meters when the first communication device is idle according to a set task scheduling method, thereby maximizing the use of communication resources between the first communication device and the smart meters and improving communication efficiency. In addition, when the number of first smart meters connected to the first communication device is 1, the method directly sends meter communication tasks in parallel to the first smart meters uniquely corresponding to each first communication device, thereby significantly improving the problems of long response time, poor availability and untimely data update of electronic equipment, thereby improving user experience.

[0049] As a first optional embodiment of this embodiment, based on the above embodiment, the construction of the tree-like communication structure information can be concretized into the following steps:

[0050] a1) According to the configuration information, determine the associated intelligent instrument connected to each communication device.

[0051] In this embodiment, the associated smart meter connected to each communication device is determined according to the configuration information defining the association relationship between the communication device and the smart meter.

[0052] b1) For each communication device, the communication device is determined as a parent node, each of the associated smart meters is determined as a child node of the communication device, and a child communication tree corresponding to the communication device is constructed.

[0053] In this embodiment, each communication device is taken as a parent node, and the smart meter associated with the communication device is taken as a child node of the communication device, so that each communication device and the smart meter associated with it constitute a sub-communication tree.

[0054] c1) Taking the electronic device as a root node, connecting each of the sub-communication trees to form a communication tree.

[0055] In this embodiment, the electronic device is used as the root node of the entire communication network, and all sub-communication trees are connected to the root node, thereby forming a complete communication tree, which includes all communication devices and smart meters.

[0056] d1) generating tree-like communication information of the communication tree based on the node information of each node in the communication tree.

[0057] In this embodiment, based on the node information (such as node status, node device identification information, etc.) of each node in the communication tree (whether it is a root node, a parent node or a child node), tree-like communication information of the communication tree is generated to monitor and manage the communication network.

[0058] The above technical scheme of this embodiment constructs a sub-communication tree by utilizing the connection relationship between the communication device and the smart meter, and connects each sub-communication tree to the root node electronic device to form a communication tree with a clear hierarchical structure. Based on the node information of each node in the communication tree, the tree-like communication information of the communication tree is generated to facilitate the subsequent determination of whether each smart device uses the communication resources of the same communication device, thereby determining the method of sending the instrument communication task, effectively improving the communication efficiency and the utilization rate of communication resources.

[0059] As a second optional embodiment of this embodiment, the steps of determining the first communication devices to which the first smart meters are respectively connected according to the pre-built tree-like communication information may be specifically optimized into the following steps:

[0060] a2) For each first smart meter, obtain meter identification information of the first smart meter.

[0061] In this embodiment, for each first smart meter, the meter identification information of the first smart meter is acquired, and the meter identification information may be a unique serial number, an IP address, a MAC address, or other information that can uniquely identify the smart meter.

[0062] b2) comparing the meter identification information with each node information in the tree-like communication information to determine first node information matching the meter identification information.

[0063] The first node information may be understood as node information matching the meter identification information, and is used to further determine the position and connection relationship of the first smart meter in the communication tree.

[0064] In this embodiment, the acquired instrument identification information is compared with each node information in the tree communication information, and the node information matching the instrument identification information is determined as the first node information.

[0065] c2) traversing the communication tree corresponding to the tree-like communication information, and determining a first node corresponding to the first node information in the communication tree.

[0066] The first node may be understood as a node representing the first smart meter in the communication tree.

[0067] In this embodiment, each node in the communication tree corresponding to the tree-like communication information is traversed and accessed, a specific node corresponding to the first node information is determined from the entire communication tree, and the specific node is determined as the first node.

[0068] d2) determining the parent node of the first node as the first communication device connected to the first smart meter.

[0069] In this embodiment, the parent node of the first node is searched in the communication tree, and the parent node represents the first communication device connected to the first smart meter.

[0070] The above technical scheme of this embodiment obtains the instrument identification information of the first smart meter, determines the first node information matching the instrument identification information from the tree communication information, and determines the corresponding first node in the communication tree according to the first node information, and then determines the parent node of the first node to achieve rapid and accurate positioning of the first communication device connected to the first smart meter, ensures accurate determination of the number of first smart meters connected to the first communication device, and provides strong support for the subsequent determination of the specific method for sending the instrument communication task.

[0071] As a second optional embodiment of this embodiment, based on the above embodiment, in the case where the number of first smart meters connected to the first communication device is greater than 1, the associated meter communication tasks are sent to each connected first smart meter in a polling manner according to a set task scheduling method, which can be specifically implemented as the following steps:

[0072] a3) The first communication device to which the number of first smart meters connected is greater than 1 is recorded as the second communication device.

[0073] In this embodiment, if it is determined that different first smart meters to be accessed are connected to the same first communication device, the first communication device is recorded as a second communication device to distinguish it from a communication device connected to only one first smart meter.

[0074] b3) For each second communication device, each first smart meter connected to the second communication device is recorded as a second smart meter, and each meter communication task associated with each second smart meter is recorded as a target communication task.

[0075] In this embodiment, for each second communication device, the first smart meter connected to the second communication device is recorded as a second smart meter, which means that the first smart meter is connected to the same second communication device, and the instrument communication tasks associated with each second smart meter are respectively recorded as target communication tasks, wherein the target communication task can be understood as a task with scheduling requirements, which can be a task such as data collection and control command issuance.

[0076] c3) determining the task priority of each of the target communication tasks, and adding the corresponding target communication tasks to a set one-dimensional communication array according to the priority from high to low.

[0077] In this embodiment, for each target communication task corresponding to the same second communication device, the task priority of each target communication task is determined. The task priority can be set according to the urgency, importance or predetermined rules of the task, and the corresponding target communication task is added to the set one-dimensional communication array in order from high to low priority for subsequent task scheduling and execution.

[0078] It should be noted that target communication tasks of the same priority level can be added to the set one-dimensional communication array in a random order.

[0079] As one implementation manner, this optional embodiment may further specify the task priority of each target communication task as follows:

[0080] c31) For each target communication task, analyzing the task attribute information to which the target communication task belongs.

[0081] In this embodiment, for each target communication task, the task attribute information described in the target communication task is analyzed to determine the type of task, such as manually initiated tasks (i.e., tasks initiated by users), monitoring tasks (i.e., tasks that require continuous monitoring or regular inspections), or timed initiated tasks (i.e., tasks that are automatically triggered according to a predetermined time). Exemplarily, the task attribute information may include task initiator information, that is, if there is a clear user identifier or operator information in the task attribute information, the corresponding target communication task can be considered to be a manually initiated task; the task attribute information may also include specific tags or classifications to directly indicate the type of task; the task attribute information may also include scheduling information such as a predetermined time and a repetition period.

[0082] c32) If the task attribute information indicates that the target communication task is a manually initiated task, determining the task priority of the target communication task to be the highest priority.

[0083] In this embodiment, if the task attribute information indicates that the target communication task is a manually initiated task, the task priority of the target communication task is determined to be the highest priority, that is, it is processed first.

[0084] c33) If the task attribute information indicates that the target communication task is a monitoring task, the target communication task is determined as the second highest priority.

[0085] In this embodiment, if the task attribute information indicates that the target communication task is a monitoring task, the task priority of the target communication task is determined to be the highest priority, that is, it is processed only after the task is manually initiated.

[0086] c34) If the task attribute information indicates that the target communication task is a timed initiation task, the task priority of the target communication task is determined to be the lowest priority.

[0087] In this embodiment, if the target communication task is characterized as a timed initiation task in the task attribute information, the task priority of the target communication task is determined to be the lowest priority, that is, it is processed last.

[0088] In the above technical scheme of the present embodiment, the priority order of tasks is determined according to the task types represented in the task attribute information, and manually initiated tasks are determined as the highest priority, thereby ensuring that the tasks with the most urgent needs or the most likely to require human participation receive the fastest response, thereby reducing the time waiting for a response after a user operation. At the same time, if human participation is required for time-consuming operations such as data processing on the data returned by the second smart device, the idle communication resources of the second communication device can be used more efficiently, thereby improving user experience and communication efficiency.

[0089] d3) When it is detected that the second communication device is in an idle state, the first target communication task in the one-dimensional communication array is sent to the associated second smart meter through the second communication device.

[0090] In this embodiment, when it is detected that the second communication device is in an idle state, the first target communication task in the one-dimensional communication array is immediately sent to the second smart meter associated with the first target communication task through the second communication device.

[0091] It should be noted that when the second communication device does not receive the target communication task to be sent to the second smart meter, or sends the received information data packet fed back by the second smart meter after responding to the target communication task to the electronic device, the second communication device is in an idle state. In addition, the first target communication task will disappear in the one-dimensional communication array after being issued, that is, the original second target communication task will become the first target communication task at this time.

[0092] The above technical scheme of this embodiment adds the corresponding target communication tasks to the set one-dimensional communication array according to the task priority of each target communication task. When it is detected that the second communication device is in an idle state, the first target communication task in the one-dimensional communication array is immediately issued, ensuring that the corresponding target communication task is issued to only one second smart meter at a time, ensuring the correctness of the data, and making full use of the idle communication resources of the second communication device, so that multiple second smart meters can communicate alternately (i.e., issue target communication tasks) using the same second communication device, greatly reducing the total communication time and the unresponsive time of user operations.

[0093] As one implementation manner, this optional embodiment may send the first target communication task in the one-dimensional communication array to the associated second smart meter through the second communication device, which is further embodied as follows:

[0094] d31) obtaining the first target communication task in the one-dimensional communication array, and using a task parsing thread to decompose the target communication task into corresponding communication commands.

[0095] In this embodiment, the first target communication task in the one-dimensional communication array is obtained, and the target communication task is decomposed into corresponding communication commands according to the intelligent meter device description file using a task parsing thread.

[0096] For example, if the target communication task is to obtain certain parameter information of the second smart meter, the target communication task is decomposed by the task parsing thread to obtain a corresponding communication command; if the target communication task is to obtain all status parameter information of the second smart meter, the target communication task is decomposed by the task parsing thread to obtain hundreds of corresponding communication commands.

[0097] d32) Encapsulating the communication command according to the set communication protocol to form a communication command data packet, and sending the communication command data packet to the associated second smart meter through the second communication device.

[0098] In this embodiment, the decomposed communication command is encapsulated according to the set communication protocol (i.e., the HART protocol) to form a communication command data packet containing all necessary information and instructions. The encapsulation process may include adding a start bit, a check bit, an end bit, etc., and the communication command data packet is sent to the associated second smart meter through the second communication device.

[0099] Exemplarily, if there is one communication command, the communication command can be directly encapsulated according to the set communication protocol to form a communication command data packet, and the communication command data packet can be sent to the associated second smart meter through the second communication device; if there are multiple communication commands, each communication command is encapsulated according to the set communication protocol to form each communication command data packet, and the second communication device can send the corresponding communication command data packet to the associated second smart meter according to the preset rules in the HART protocol.

[0100] The above technical solution of this embodiment uses a task parsing thread to decompose the first target communication task into corresponding communication commands, and encapsulates them according to the set communication protocol to form a communication command data packet that can be sent to the associated second smart meter through the second communication device, thereby ensuring effective communication between the electronic device and the smart meter.

[0101] As one implementation manner, after sending the first target communication task in the one-dimensional communication array to the associated second smart meter through the second communication device, the method further includes:

[0102] a4) receiving, through the second communication device, an information data packet fed back by the associated second smart meter after responding to the target communication task, so as to participate in related execution logic according to the information data packet.

[0103] The information data packet may be understood as a data packet returned by the second smart meter after receiving and processing the target communication task, and may include execution results, status information, error codes, and the like.

[0104] In this embodiment, the second communication device receives the feedback information data packet of the associated second smart meter after responding to the target communication task, and sends the information data packet to the electronic device. At the same time, the communication state of the second communication device can be determined as an idle state. After receiving the information data packet, the electronic device participates in the relevant execution logic according to the information data packet, such as performing secondary processing of the data or continuing to send it to the user interaction interface for user interaction. Exemplarily, the relevant execution logic may include data parsing, result verification (i.e., checking whether the feedback information indicates that the task is successfully executed), error handling (i.e., if the information data packet indicates an error or abnormality, error recovery or alarm logic may be executed), status update (i.e., updating the data recorded by the electronic device, the status of the smart meter, etc. according to the information data packet), subsequent operations (i.e., determining whether it is necessary to send more communication commands or perform other tasks according to the information data packet) and user notification (i.e., notifying the user of the execution result of the task), etc. If it is necessary to interact with the user, the parsed data can also be displayed in the user interaction interface of the electronic device.

[0105] It should be noted that at this time, the second communication device can execute the operation of sending the target communication task to the remaining second smart meters, and no longer execute the remaining operations on the current second smart meter (i.e., the second smart meter that currently feeds back the information data packet), so it is not affected by the relevant execution logic such as data processing or interaction. After the relevant execution logic is completed and the target communication task for the current second smart meter is prepared again, the processing will continue according to the preset rules.

[0106] The above technical solution of this embodiment receives, through the second communication device, an information data packet fed back by the associated second smart meter after responding to the target communication task, and executes relevant logic according to the information data packet to ensure that the electronic device can achieve effective behavior adjustment and data management according to the response of the second smart meter.

[0107] As another implementation method, the following is also included:

[0108] a5) If it is detected that a new meter communication task is generated for any second smart meter, the new meter communication task is recorded as a new target communication task.

[0109] In this embodiment, if it is detected that a new meter communication task is generated for any second smart meter, the new meter communication task is recorded as a new target communication task to participate in task scheduling.

[0110] Exemplarily, the new meter communication task may be a meter communication task regenerated after the electronic device executes relevant logic on the information data packet fed back by the second smart meter.

[0111] b5) determining the task priority of the new target communication task, and inserting the new target communication task into the one-dimensional communication array according to the task priority.

[0112] Exemplarily, a specific method of determining the task priority of a new target communication task and inserting the new target communication task into a one-dimensional communication array according to the task priority may be to analyze the task attribute information of the new target communication task to determine whether the new target communication task is a manually initiated task, a monitoring task, or a timed initiated task, thereby determining the task priority of the new target communication task; then inserting the new target communication task into the end of the same task priority in the one-dimensional communication array. If the new target communication task is a manually initiated task, the task priority is the highest priority. In this case, the new target communication task is inserted behind the last highest priority target communication task in the one-dimensional communication array; or when there is no target communication task with the same task priority in the one-dimensional communication array, the new target communication task is inserted into the corresponding position according to the task priority. If the new target communication task is a manually initiated task with the highest priority, and there is no target communication task with the highest priority in the one-dimensional communication array, the new target communication task is inserted into the first target communication task in the one-dimensional communication array, waiting to be processed first when the second communication device is in an idle state.

[0113] The above technical solution of this embodiment, by inserting the new instrument communication task generated for any second smart meter into the one-dimensional communication data group according to the task priority, ensures that high-priority tasks can be processed first and continuously, and improves the fastest response to the tasks with the most urgent needs or the most likely to require human participation, thereby further improving user experience and communication efficiency.
