Description

Technical Field

[0001] The present invention relates to the technical field of remote upgrade systems for electric power meter reading concentrators, and in particular to a remote upgrade system and method for electric power meter reading concentrators based on a 4G communication module. Background Art

[0002] With the rapid development of smart grid technology, the importance of power meter reading system as an important part of power grid operation monitoring and management is becoming increasingly prominent. Traditional power meter reading system usually uses manual meter reading or low-speed wired communication for data transmission. This method has problems such as low data collection efficiency, poor real-time performance, and high maintenance cost, which makes it difficult to meet the needs of modern smart grids. In order to solve these problems, power companies have gradually introduced remote meter reading systems based on wireless communication technology, in which concentrators play a key role in meter reading systems.

[0003] The power meter reading concentrator (hereinafter referred to as the concentrator) is a device used to collect, aggregate and forward the meter data of power users. It is usually installed in areas where power users are concentrated. By communicating with multiple meters, it centrally obtains user power consumption information and transmits this information to the power company's backend system. With the widespread deployment of smart meters, the functions of the concentrator are gradually enhanced, including but not limited to data collection, storage, forwarding and equipment management. However, with the continuous increase in the number of concentrators and the complexity of their application environment, remote management and software upgrades of concentrators have become an increasingly important issue.

[0004] 1. Challenges in upgrading traditional electricity meter reading systems

[0005] In traditional power meter reading systems, firmware or software upgrades of concentrators usually require technicians to go on-site to perform operations. This method not only consumes a lot of manpower and time, but also faces many difficulties in actual operation. For example:

[0006] Complex on-site operations: Since the concentrators are widely distributed, technicians need to go to each installation site to perform on-site upgrade operations, which is a complex and time-consuming operation.

[0007] High maintenance cost: On-site upgrades require a lot of manpower and equipment investment, especially when the concentrators are located in remote areas or harsh environments, the maintenance cost increases significantly.

[0008] Low upgrade efficiency: On-site upgrades are affected by uncontrollable factors such as personnel arrangements and weather, resulting in low upgrade efficiency and an inability to quickly respond to system requirements.

[0009] Security and consistency are difficult to guarantee: During on-site operations, human error or equipment failure may lead to upgrade failure, or even data loss or equipment damage. In addition, the upgrade progress and versions in different regions may be inconsistent, affecting the overall performance and security of the system.

[0010] With the development of smart grids and the increase in demand, traditional on-site upgrade methods can no longer meet the requirements of modern power systems. How to achieve remote upgrades of concentrators has become an urgent problem that power companies need to solve.

[0011] 2. Necessity and challenges of remote upgrade

[0012] In order to solve the shortcomings of traditional methods, remote upgrade technology came into being. Remote upgrade refers to the transmission of upgrade packages or patch files from the server to the concentrator through remote communication, and the concentrator automatically completes the software or firmware upgrade. Compared with the traditional on-site upgrade method, remote upgrade has the following advantages:

[0013] Reduce maintenance costs: Remote upgrades do not require technicians to be on-site for operation, which reduces labor and equipment investment and significantly reduces maintenance costs.

[0014] Improve upgrade efficiency: Through remote upgrade, batch upgrades of large-scale concentrators can be completed in a short time, significantly improving upgrade efficiency.

[0015] Enhanced system security: Through centralized management and automated operations, remote upgrades can effectively reduce the risk of human operational errors and ensure the security and reliability of the upgrade process.

[0016] Improve system consistency: Remote upgrade can achieve unified management and version control of all concentrators, ensure the consistency of software versions of various parts of the system, and optimize system performance.

[0017] However, remote upgrades also face some challenges in practical applications, mainly including the following aspects:

[0018] Stability of the communication network: Concentrators are usually installed in different geographical locations with complex environments, and the coverage and signal strength of 4G networks may vary. How to ensure reliable transmission of upgrade packages in an environment with unstable networks or poor signals is an important issue facing remote upgrades.

[0019] Security of data transmission: During the remote upgrade process, the upgrade package needs to be transmitted through a public communication network (such as a 4G network), which poses the risk of data being intercepted, tampered with, or forged. How to ensure the confidentiality, integrity, and authenticity of data during transmission is an important consideration for remote upgrade technology.

[0020] Equipment compatibility and fault tolerance: The models, hardware configurations, and operating environments of concentrators vary. How to ensure that the upgrade package is compatible with the hardware and software environments of different devices, and handle unexpected situations (such as power outages, network interruptions) during the upgrade process without damaging the normal operation of the equipment, is a problem that must be solved by remote upgrades.

[0021] Controllability and manageability of the upgrade process: Remote upgrade involves the parallel operation of multiple devices. How to monitor and manage the upgrade progress, status and results of each device, timely discover and handle abnormal situations, and ensure the controllability and reliability of the entire upgrade process are the key to the design of the remote upgrade system.

[0022] 3. Shortcomings of existing remote upgrade technology

[0023] Although some remote upgrade technologies based on wireless communication have been applied to power meter reading systems, there are still some shortcomings in practical applications:

[0024] Poor network adaptability: When the network quality is poor, some remote upgrade systems are prone to data transmission failure, upgrade interruption and other problems. The lack of effective breakpoint resumption and automatic recovery mechanisms leads to low upgrade efficiency.

[0025] Insufficient security protection: Some systems lack a complete data encryption and security authentication mechanism. Data can be easily intercepted or tampered with during transmission, posing a major security risk.

[0026] Poor compatibility and versatility: Due to the diversity of hardware platforms and software environments, existing upgrade solutions lack good compatibility between different types of concentrators, making them difficult to promote and popularize.

[0027] Lack of a unified management platform: Most existing remote upgrade solutions lack a unified management platform, making it difficult to centrally monitor and manage the concentrator, and the operation and maintenance are complex. Summary of the invention

[0028] The object of the present invention is to provide a remote upgrade system for a power meter reading concentrator based on a 4G communication module, the system comprising:

[0029] Electricity meter reading concentrator: It has a built-in 4G communication module, which establishes a communication connection with the remote server through the 4G network to receive and install upgrade packages from the server;

[0030] Remote server: used to store and manage the upgrade packages of the concentrator, receive connection requests from the concentrator, and push the latest upgrade packages to it according to the version information of the concentrator;

[0031] Management terminal: used by operators to issue remote upgrade instructions and monitor the status and upgrade progress of the concentrator in real time;

[0032] Security authentication module: used to perform two-way authentication on the communication between the concentrator and the server, preventing unauthorized devices from participating in the upgrade process and ensuring the security and integrity of data transmission.

[0033] As a preferred technical solution of the present invention, the 4G communication module is further configured to support multiple communication protocols, including TCP / IP, UDP, HTTP / HTTPS and other protocols, to adapt to different network environments and data transmission requirements, and to achieve encrypted data transmission through the SSL / TLS encryption protocol to prevent data from being intercepted or tampered with during transmission.

[0034] As a preferred technical solution of the present invention, the power meter reading concentrator comprises:

[0035] Storage unit: used to store received upgrade packages, currently running firmware versions, and historical version data;

[0036] Processing unit: configured to parse the upgrade package, perform the upgrade operation, and roll back to the previous version when the upgrade fails;

[0037] Status monitoring module: used to monitor the status information of the upgrade process in real time, including network connection status, data transmission rate, integrity of received data, and abnormal conditions in the upgrade process.

[0038] As a preferred technical solution of the present invention, the system has a breakpoint resume function. When the network is interrupted or the data transmission fails, the data transmission between the server and the concentrator will be automatically suspended. After the network is restored or the error is repaired, the system will continue the data transmission from the position where the last transmission was interrupted, ensuring the continuity and integrity of the upgrade process. The algorithm of breakpoint resume is as follows:

[0039] Position marker = sequence number of the last received data packet.

[0040] As a preferred technical solution of the present invention, the remote server is configured to update the power meter concentrator according to the unique identifier ID and the current version number V current Perform authentication and version comparison to determine whether the concentrator needs to be upgraded, and determine whether to push the upgrade package based on the comparison results. The judgment formula is as follows:

[0041]

[0042] Among them, V new The latest version number stored on the server.

[0043] As a preferred technical solution of the present invention, the power meter reading concentrator uses a CRC check algorithm to verify the integrity of the data packet when receiving each data block to ensure that the data packet is not damaged or tampered with during transmission. The CRC check value calculation formula is as follows:

[0044] CRC result =CRC(D)

[0045] Where D is the received data packet and CRC() is the cyclic redundancy check function.

[0046] As a preferred technical solution of the present invention, after installing the upgrade package, the power meter reading concentrator automatically executes a self-test program to detect the correctness and integrity of the upgraded firmware. The self-test includes but is not limited to system startup test, core module function test, and communication module connection stability test. If the test result meets the set safety conditions, the concentrator resumes normal operation; if the test fails, the system automatically rolls back to the version before the upgrade and generates a fault report.

[0047] The present invention also proposes a remote upgrade method for an electric power meter reading concentrator based on a 4G communication module, comprising the following steps:

[0048] S1: The power meter reading concentrator establishes a communication connection with the remote server through the 4G communication module, and sends the current version information and upgrade request to the server;

[0049] S2: The remote server verifies the identity and version information of the concentrator and determines whether the concentrator needs to be upgraded;

[0050] S3: If the server determines that an upgrade is needed, it sends the upgrade package in blocks to the concentrator, which receives the data block by block and verifies the integrity of each data block;

[0051] S4: After receiving the entire upgrade package, the concentrator parses the upgrade package and performs the upgrade operation, and monitors the data integrity and system status in real time during the upgrade process;

[0052] S5: After the upgrade is completed, the concentrator performs a self-check procedure. If the self-check passes, the concentrator enters normal operation. If the self-check fails, a rollback operation is performed to restore the system to the state before the upgrade, and the server is notified of the specific reasons for the upgrade failure.

[0053] As a preferred technical solution of the present invention, in step S3, the server dynamically adjusts the size and transmission speed of the data block according to the current network status and data transmission rate to ensure that the upgrade package can be stably transmitted even when the network quality is poor. The data block size adjustment formula is as follows:

[0054] Data block size = (network bandwidth, packet loss rate, delay)

[0055] Where f() is an adaptive function based on the real-time network status.

[0056] As a preferred technical solution of the present invention, in step S5, when the self-test program of the concentrator detects that there is a problem with the upgraded system, the concentrator will automatically trigger the fault diagnosis program, record detailed error logs and system status information, and feed back this information to the remote server through the 4G communication module for subsequent analysis and processing. The diagnostic information includes but is not limited to error codes, verification information of the upgrade package, system operation logs and hardware status reports.

[0057] Compared with the prior art, the beneficial effects of the present invention are as follows:

BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Figure 1This is a system block diagram of a remote upgrade system for an electric power meter reading concentrator based on a 4G communication module proposed by the present invention. DETAILED DESCRIPTION

[0065] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 are within the scope of protection of the present invention.

[0066] The present invention relates to a remote upgrade system and method for an electric power meter reading concentrator based on a 4G communication module. The system communicates data with a remote server through an electric power meter reading concentrator with a built-in 4G communication module to achieve remote management and software upgrade. The following is a detailed description of a specific implementation method.

[0067] Implementation 1: System architecture and component description

[0068] Electricity meter reading concentrator:

[0069] The concentrator has a built-in 4G communication module, which can communicate with the remote server via the 4G network. The 4G module supports multiple communication protocols, such as TCP / IP, UDP, HTTP / HTTPS, etc., ensuring stable communication in different network environments.

[0070] The concentrator includes a storage unit and a processing unit. The storage unit is used to store received upgrade packages, the currently running firmware version, and historical version data. The processing unit is responsible for parsing and installing the upgrade package, and rolling back to the previous version when the upgrade fails.

[0071] The concentrator also integrates a status monitoring module to monitor the network connection status, data transmission rate, integrity of received data, abnormal conditions during the upgrade process, etc. in real time to ensure the stability of the entire upgrade process.

[0072] Remote Server:

[0073] The server is used to store and manage the upgrade package of the power meter reading concentrator. When the concentrator initiates an upgrade request, the server verifies the identity of the concentrator and determines whether an upgrade is required based on the version information of the concentrator.

[0074] The server is also responsible for sending the upgrade package to the concentrator in blocks. Block transmission can effectively avoid data loss or transmission failure during large file transmission.

[0075] Management terminal:

[0076] The management terminal is an interface for operators to use, which can remotely issue upgrade instructions, monitor the upgrade process, view real-time status information, and intervene when necessary.

[0077] Security authentication module:

[0078] This module is used to establish two-way authentication between the concentrator and the server. By adopting the SSL / TLS encryption protocol, it ensures that the upgrade package will not be intercepted or tampered with during transmission.

[0079] The concentrator and server use a two-way authentication mechanism to ensure that only authenticated devices can participate in the upgrade process.

[0080] Implementation Method 2: System Workflow

[0081] Establish a communication connection:

[0082] After the concentrator is started, it establishes a connection with the remote server through the 4G communication module. When the connection is established, both parties authenticate their identities through the security authentication module. After the authentication is passed, the concentrator sends the current firmware version number V current and the device's unique identifier ID to the server.

[0083] Determine whether an upgrade is needed

[0084] After receiving the version information sent by the concentrator, the server queries the latest firmware version number V stored in its own database new .Pass

[0085] Over comparison V new With V current , determine whether the concentrator needs to be upgraded.

[0086] The judgment formula is as follows:

[0087]

[0088] Block transfer upgrade package:

[0089] If an upgrade is required, the server will prepare an upgrade package for transmission; otherwise, the upgrade process ends. The server adaptively selects the data block size based on the network conditions and sends the upgrade package to the concentrator in blocks. The size of each data block is adjusted according to the real-time network bandwidth, packet loss rate and delay. The calculation formula is as follows:

[0090] Data block size = f (network bandwidth, packet loss rate, delay) After receiving each data block, the concentrator immediately performs a CRC check to ensure the integrity of data transmission. The check formula is as follows:

[0091] CRC result =CRC(D)

[0092] Wherein, D is the received data block, and CRC() is the cyclic redundancy check function.

[0093] Perform the upgrade operation:

[0094] When the concentrator receives the complete upgrade package, the processing unit parses the upgrade package content and starts to perform the upgrade operation. During the upgrade process, the status monitoring module monitors the upgrade process in real time to ensure the integrity of the data and the stability of the system.

[0095] If a network anomaly or data transmission error is detected during the upgrade process, the system will automatically pause the upgrade and try to resume the upgrade after the network is restored.

[0096] Self-check and rollback:

[0097] After the upgrade is completed, the concentrator automatically performs a self-test program to check the correctness and integrity of the new firmware. The self-test includes system startup test, core module function test, communication module connection stability test, etc.

[0098] If the self-test passes, the concentrator resumes normal operation and sends a success confirmation message to the server; if the self-test fails, the concentrator automatically rolls back to the version before the upgrade and sends a fault report to the server.

[0099] Troubleshooting and logging:

[0100] If the self-check fails or an abnormality occurs during the upgrade process, the concentrator will automatically trigger the fault diagnosis program and record detailed error logs and system status information. This information includes error codes, upgrade package verification information, system operation logs, and hardware status reports.

[0101] Fault information is fed back to the server through the 4G communication module for operators to analyze and process.

[0102] Implementation method 3: breakpoint resume mechanism

[0103] During the upgrade process, if the network is interrupted or data transmission fails, the concentrator and server will automatically enable the breakpoint resume function. The server will record the last successful data block sequence number of each transmission, and the concentrator will mark the location of the transmission interruption based on the reception situation.

[0104] Once the network is restored, the server and concentrator will continue data transmission from the point where the last transmission was interrupted. This mechanism effectively avoids repeated data transmission, reduces bandwidth waste and time delay.

[0105] Implementation method 4: security authentication and data encryption

[0106] The system uses SSL / TLS encryption protocol throughout the upgrade process to ensure that data is not intercepted or tampered with during transmission. All transmitted data blocks are encrypted and can only be decrypted by authenticated concentrators and servers.

[0107] The security authentication module establishes a two-way authentication mechanism between the concentrator and the server. The server checks the concentrator's device identifier ID and authentication certificate to ensure that only legitimate devices participate in the upgrade process. Similarly, the concentrator verifies the server's identity to prevent malicious servers from pushing unsafe upgrade packages.

[0108] Implementation method 5: Remote management and upgrade monitoring

[0109] The management terminal provides a user-friendly interface for operators to remotely monitor the upgrade status of the concentrator. Operators can view the concentrator's connection status, data transmission rate, upgrade progress, and possible abnormal situations in real time.

[0110] When necessary, the management terminal can terminate the upgrade process, restart the system, or change the upgrade strategy, such as adjusting the data block size and transmission speed, to adapt to changes in the current network environment.

[0111] Implementation method 6: Upgrade package optimization and transmission strategy

[0112] The upgrade package uses differential upgrade technology, that is, only the difference between the old version and the new version is transmitted, reducing the amount of transmitted data and improving transmission efficiency. The server generates a differential package by analyzing the current version and target version of the concentrator and transmits it in blocks.

[0113] After the differential data packets are transmitted to the concentrator via the 4G network, the concentrator re-synthesizes the complete upgrade package locally for installation and update operations. This method significantly reduces the time and bandwidth resources required for the upgrade.

[0114] in conclusion

[0115] Through the above specific implementation methods, the electric power meter reading concentrator remote upgrade system and method based on 4G communication module of the present invention realizes efficient, stable and safe remote upgrade of the electric power meter reading concentrator. The use of 4G communication technology and multi-level security mechanism ensures the security of data transmission and the reliability of system upgrade. The combination of breakpoint resume, differential upgrade and remote monitoring technologies significantly improves the upgrade efficiency and operation stability of the system, and provides reliable technical support for the intelligent management of the electric power meter reading system.
