Description

Technical Field

[0001] The present invention relates to the technical field of relay protection and detection devices, and in particular to a complete automatic upgrading method and system for relay protection and detection devices of different voltage levels. Background Art

[0002] Relay protection and control devices are equipment used to protect power systems. Their main function is to detect abnormal conditions in the power system and isolate faults and protect the stable operation of the system by controlling switches, circuit breakers and other equipment in the power system. Relay protection and control devices play a vital role in the safe operation of the power system. They ensure the stable operation of the power system, reduce fault losses, and improve the reliability and availability of the power system.

[0003] Due to the complexity of the architecture of the relay protection and control devices themselves and the requirements for operational stability, the following problems arise.

[0004] (1) There are many steps to upgrade relay protection and control devices, usually including more than a dozen steps, such as connecting the device, opening the upgrade package, upgrading the HMI plug-in BSP, restarting the device, upgrading the CPU plug-in BSP, restarting the device, upgrading the CPU application, upgrading the HMI application, restarting the device, version synchronization, initializing the setting area, and solidifying the setting area.

[0005] (2) The interface operations of the relay protection and control device upgrade steps are relatively complicated. For example, many options need to be selected to complete the operation of the current step, such as communication connection, version synchronization, initialization of setting area and solidification of setting area.

[0006] (3) The hardware structures of high, medium and low voltage relay protection and control devices are different, resulting in different upgrade methods for different devices. Usually, low voltage protection devices use a single plug-in dual computing chip hardware structure, while high and medium voltage devices use a multi-plug-in hardware structure, but each plug-in has only one computing chip. The hardware structures of different devices lead to inconsistent upgrade methods, which increases the threshold and complexity of device upgrades.

[0007] (4) The interface usability and human-computer interaction capabilities of traditional relay protection and control device upgrade tools are relatively poor.

[0008] (5) Traditional relay protection and control device upgrade tools do not support cross-platform and have poor compatibility. Summary of the invention

[0024] The whole machine upgrade is completed by setting a whole machine upgrade tool for automatically connecting, disconnecting and switching connections with different plug-ins of the relay protection device.

[0025] According to one aspect of the present invention, the communication adaptation of different upgrade steps with high voltage, medium voltage and low voltage relay protection devices respectively according to physical characteristics and hardware differences includes:

[0026] Autonomously adapt different upgrade steps to different hardware structures in high-voltage, medium-voltage and low-voltage relay protection devices, and interact with each hardware structure for all upgrade service communication messages;

[0027] Among them, the upgrade service includes communication Socket connection, file reading, file writing, upgrade verification, status update, device restart, version synchronization and fixed value area solidification.

[0035] The present invention can realize autonomous identification and adaptation of the hardware structure of high, medium and low voltage relay protection devices. Because the business logic of the high and medium voltage relay protection device is composed of 3 CPU plug-ins, each plug-in contains only one CPU chip, one of which is used to run the human-computer interaction interface (also called HMI plug-in), and the other two CPU plug-ins are responsible for business logic operations; the business logic of the low voltage relay protection device is composed of a CPU plug-in, but this CPU plug-in contains 2 CPU chips, one of which is used to run the human-computer interaction interface, and the other CPU chip is responsible for business logic operations. It can be seen that the hardware structure of different devices leads to inconsistent upgrade methods, which increases the threshold and complexity of device upgrades. The present invention can solve the problems of high threshold and complexity, help the device upgrade tool no longer distinguish the hardware structure of high, medium and low voltage relay protection devices, can perfectly adapt and connect high, medium and low voltage relay protection devices, and realize the unification of the connection method of high, medium and low voltage relay protection devices, which greatly simplifies the operation difficulty and reduces the learning cost and operation and maintenance cost.

[0080] The present invention simplifies some complicated interface operations of the relay protection device.

[0081] The present invention can realize autonomous identification and adaptation of the hardware structure of high, medium and low voltage relay protection devices.

[0082] Furthermore, based on the above solution, the solution of the present invention is described in detail in the following in conjunction with the accompanying drawings in the form of a specific embodiment.

[0083] Example 1

[0084] The whole machine automatic upgrade system of relay protection and measurement devices of different voltage levels includes: a human-computer interaction module, an automatic upgrade module and a communication agent module developed based on C++ and XML languages.

[0085] The human-computer interaction module is mainly used to provide users with a humanized operation interface to automatically upgrade the relay protection device. In this embodiment, the module mainly improves the usability, stability and work efficiency through the following aspects.

[0086] Reduce the operation steps of complex operation interfaces. The traditional communication connection interface requires the user to select a drop-down box and an input box, which reduces the previous ten or so information inputs to three. The traditional single-step device upgrade tool connection operation requires input of the device name, device IP, device port, device type, plug-in type, slave serial number, encryption, login password, whether to delete temporary files, and whether to display component information. After logic integration and interface optimization in this embodiment, the whole machine automatic upgrade tool reduces the input to 3: device IP, device port, device type, and login password.

[0087] This embodiment adds a drop-down box linkage on the communication connection interface, and after logic integration and interface optimization, the input information and device type are automatically associated and selected, and the user no longer needs to manually select and input this information.

[0088] This embodiment adds a scheduling interface to perform a global scheduling display and tracking of all upgrade steps involved in the medium and high voltage relay protection devices, allowing users to understand the progress of the current step in the entire upgrade process and the specific execution status of each upgrade step in real time. Figure 2 As shown in the figure, in the scheduling interface, users can see that the entire upgrade process is divided into multiple steps, and each step has a corresponding progress bar and status indicator. When a step is completed, the progress bar will automatically move forward and display the execution result of the step. If a step fails, the progress bar will stop at the step and display an error message so that users can handle it in time. In addition, the scheduling interface also provides some other functions, such as pausing / resuming the upgrade, rolling back to the previous step, viewing the upgrade log, etc., to facilitate users to manage and control the upgrade process. By adding a scheduling interface, users can more intuitively understand the progress and execution of the upgrade process, thereby improving the transparency and controllability of the upgrade process. At the same time, users can also manage and control the upgrade process more conveniently, improving the reliability and stability of the upgrade process.

[0089] Automatic upgrade module, which mainly integrates all key upgrade steps of high, medium and low voltage relay protection devices to achieve the goal of automatic whole machine upgrade. These key steps include but are not limited to HMI plug-in BSP upgrade, restart device, CPU plug-in BSP upgrade, restart device again, CPU application upgrade, HMI application upgrade, restart device again, version synchronization, initialization of fixed value area and solidification of fixed value area, etc.

[0090] In this embodiment, it is analyzed that the upgrade of the low-voltage protection device needs to go through 12 steps, including communication connection, opening the upgrade package, HMI plug-in BSP upgrade, restart device, CPU plug-in BSP upgrade, restart device, CPU application upgrade, HMI application upgrade, restart device, version synchronization, initialization of fixed value area and solidification of fixed value area. The upgrade of medium and high voltage devices requires 15 steps, specifically communication connection, opening the upgrade package, HMI plug-in BSP upgrade, restart device, upgrade HMI application, BSP upgrade of CPU plug-in 1, restart device, application upgrade of CPU plug-in 1, BSP upgrade of CPU plug-in 2, restart device, application upgrade of CPU plug-in 2, restart device, version synchronization, initialization of fixed value area and solidification of fixed value area. Moreover, these steps need to be completed manually one by one, which is not only extremely time-consuming and labor-intensive, but also quite inefficient.

[0091] The excellence of the automatic upgrade module is that it successfully simplifies the 12 steps of low-voltage protection upgrade to only 3 steps: communication connection, opening the upgrade package, and upgrading the whole machine. Similarly, the 15 steps of medium and high voltage device upgrades have also been simplified to 3 steps: communication connection, opening the upgrade package, and upgrading the whole machine, thus greatly improving work efficiency.

[0092] Automated tools have replaced manual operations, which not only reduces the probability of operational errors, but also reduces the time required for operations. While work efficiency has been greatly improved, labor costs have also been significantly reduced.

[0093] The implementation principle is that after in-depth logical analysis and comprehensive summary, the device upgrade tool optimizes the upgrade steps into three core steps: communication connection, opening the upgrade package and upgrading the whole device. The upgrade steps for the low-voltage relay protection device include the previous HMI plug-in BSP upgrade, restarting the device, CPU plug-in BSP upgrade, restarting the device, CPU application upgrade, HMI application upgrade, restarting the device, version synchronization, initialization of the fixed value area and solidification of the fixed value area. The upgrade steps for the medium and high voltage relay protection device include the previous HMI plug-in BSP upgrade, restarting the device, upgrading the HMI application, CPU plug-in 1 BSP upgrade, restarting the device, CPU plug-in 1 application upgrade, CPU plug-in 2 BSP upgrade, restarting the device, CPU plug-in 2 application upgrade, restarting the device, version synchronization, initialization of the fixed value area and solidification of the fixed value area. The device upgrade tool successfully realizes the automatic connection, disconnection and switching connection between the device upgrade tool and different device plug-ins by encapsulating the business logic and realizing the switching management of the communication connection. As a result, the device upgrade tool can display a series of steps such as HMI plug-in BSP upgrade, restart device, CPU plug-in BSP upgrade, restart device, CPU application upgrade, HMI application upgrade, restart device, version synchronization, initialization of fixed value area and solidification of fixed value area as a unified step - whole machine upgrade. In terms of implementation effect, practical results show that after adopting the present invention, the upgrade efficiency of the production center production line device is improved by 30%, and it also helps to improve the efficiency of on-site engineering operation and maintenance by 25%.

[0094] The communication agent module is mainly used for the automatic upgrade module to autonomously adapt to the different hardware structures of high, medium and low voltage relay protection devices, and to interact with them through communication messages for all services. These services include communication socket connection, file reading, file writing, upgrade verification, status update, device restart, version synchronization, constant value area solidification, etc. At present, the hardware structures of mainstream medium and high voltage relay protection devices and low voltage relay protection devices are different. The business logic of medium and high voltage relay protection devices is composed of 3 CPU plug-ins, each of which contains only one CPU chip, one of which is used to run the human-computer interaction interface, and the other two CPU plug-ins are responsible for business logic operations; the business logic of low voltage relay protection devices is composed of a CPU plug-in, but this CPU plug-in contains 2 CPU chips, one of which is used to run the human-computer interaction interface, and the other is responsible for business logic operations.

[0095] Due to the hardware differences between low-voltage protection devices and medium- and high-voltage devices, the connection methods between tools and devices are also very different, resulting in higher learning costs and operating thresholds.

[0096] Implementation principle: Figure 3 As shown, the automatic upgrade module and the communication agent module interact with each other through the Socket method.

[0097] The communication agent module configures the IP mapping relationship inside the device through the link_setting.xml file, thereby ensuring that the automatic upgrade module can connect to plug-ins with different hardware structures inside the device (HMI plug-in, CPU1 plug-in, CPU2 plug-in, CPU plug-in core 0 and CPU plug-in core 1) through a network port. The link_setting.xml file structure is shown below, where Links is the root directory tag and Link is the connection mapping tag. Key attributes id (connection sequence number), sAddr (IP address of the network port of the automatic upgrade module connected to the device), sPort (port number of the network port of the automatic upgrade module connected to the device), cAddr (IP address mapped by the communication agent module), cPort (port number mapped by the communication agent module).

[0098] Through the IP address mapping and forwarding of the link_setting.xml file, the automatic upgrade module can connect to the required IP addresses of different hardware structures inside the device through one network port. Implementation effect: The communication agent module helps the device upgrade tool to no longer distinguish the hardware structure of high, medium and low voltage devices, and can perfectly adapt and connect high, medium and low voltage relay protection devices, realizing the unification of the connection method of high, medium and low voltage relay protection devices, greatly simplifying the operation difficulty and reducing the learning cost and operation and maintenance cost.
