Description

Technical Field

[0001] The present invention relates to the technical field of power system substation equipment, and in particular to a substation equipment panel cabinet management system. Background Art

[0002] In the substation of the power system, the correct operation and management of substation equipment is crucial to ensure the reliable transmission of electricity. However, the current on-site operation mode faces many challenges, especially in the environment of multi-professional and multi-trade cross-operation. These problems not only affect work efficiency, but also may bring safety hazards. The following is a further specific description of the above problems:

[0003] 1. "Working Here" logo on different devices:

[0004] In substations, the "Work Here" signs on different equipment are often of the same style, which makes it difficult for operators to quickly determine which areas are allowed to work and which areas are prohibited when checking the signs.

[0005] Because the signs cannot be distinguished intuitively, operators may mistakenly enter unauthorized areas or areas where other operations are in progress, which increases the risk of mistakes and may interfere with ongoing work or even cause safety accidents.

[0006] 2. Universality of cabinet keys:

[0007] The cabinet keys used in substations are often universal, which may result in operators who are unfamiliar with the on-site environment opening cabinets outside the working location without authorization.

[0008] This situation may not only lead to information leakage and equipment misoperation, but also increase safety risks. For example, mistakenly turning on certain electrical equipment may cause equipment damage or unstable output, posing a threat to the stability of the entire power system.

[0009] 3. Conflict between work permit and safety measures:

[0010] In substation operations, the safety measures required by each work ticket often conflict, which requires frequent adjustments and notes on each work ticket, and constant communication with the relevant work leaders to ensure safety.

[0011] Such frequent adjustments not only waste time, but may also cause confusion among operators about the understanding and implementation of safety measures, thus affecting the safety and efficiency of operations.

[0012] 4. Complexity of sign layout

[0013] At large-scale maintenance or technical transformation sites, hundreds of signboards are required to guide operations in substations. However, the verification and installation of signboards are cumbersome and can easily lead to mixing or mis-installation.

[0014] Incorrect sign placement may mislead workers into entering live compartments, leading to high-level violations and even serious accidents. This situation highlights the urgent need for sign management and personnel training. Summary of the invention

Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0091] Example 1

[0092] In view of the equipment cabinet management in the substation, this embodiment provides a substation equipment cabinet management system. The substation equipment cabinet management system is based on a number of substation equipment cabinets. Each electrical equipment cabinet is equipped with an intelligent lock. The intelligent lock adopts a small and ultra-thin intelligent lock that matches the equipment cabinet door purchased on the market, and has a built-in battery and sound and light alarm. The intelligent lock is equipped with a door card and a mechanical key. The intelligent lock is wirelessly connected to the background terminal through a wireless signal transmitter. The background terminal includes a PC, an office computer, and a card reader. The PC, the office computer, and the card reader are connected to the computer server and connected to the wireless signal transmitter through a computer service. The background terminal is located in the substation control room, and the background terminal is wirelessly connected to the distributed display device through a wireless signal transmitter. The distributed display device is arranged on the front and rear doors of each group of equipment cabinets. The distributed display device is an independent unit, which adopts an ultra-low power color electronic ink screen. The distributed display device displays text and images according to the instructions of the background terminal, and dynamically updates the size, color, and refresh frequency of the text and image. The smart lock is equipped with a door card that the operator carries with him; the door card uses an NFC chip, and the NFC chip is placed in a sealed shell with good waterproof, dustproof, vibration-proof and electromagnetic compatibility properties.

[0093] The wireless signal transmitter can send background terminal instructions to the distributed display device and the smart lock, and feed back the distributed display device and the smart lock to the background terminal; the wireless signal transmitter performs networking communication via Bluetooth or a 2.4GHz local area network.

[0094] In addition, the substation cabinet management system also includes monitoring equipment, which includes temperature and humidity sensors, current sensors, and voltage sensors installed in each electrical equipment cabinet. The monitoring equipment is connected to the distributed display device and the wireless signal transmitter through the collector.

[0095] The background terminal of the substation cabinet management system is the core of the system, including PCs, office computers, card readers and writers, and application software. The software is written in C++ with a visual window, supports offline upgrades, and has functions such as viewing, editing, setting, master control, statistics, and alarms. In C++, programs with visual windows (also called graphical user interfaces, GUIs) are usually implemented through some specific graphics libraries, which provide functions for creating user interface components such as windows, buttons, and text boxes; commonly used graphics libraries include Qt, wxWidgets, SFML, and GTKmm. Qt is a cross-platform C++ library that is widely used in the development of GUI applications. It provides rich functions and components, can create complex user interfaces, and can be developed through QtCreator; wxWidgets is another cross-platform C++ library that provides a localized user interface and supports multiple operating systems, including Windows, macOS, and Linux; SFML (Simple and Fast Multimedia GTKmm is a C++ interface of GTK+, which is used to create GUI applications and is mainly used in Linux environment. It is used to view the real-time opening / locking status of all cabinet doors and verify the settings of cabinet warning signs with one click. It can edit the text, graphics, size, color, refresh rate and other parameters required for each cabinet and update them dynamically. It can set the cabinet signs of station equipment with one click. It can remotely open the cabinet door locks or authorize the staff to open the cabinet door locks in the specified time period through door card authorization. It can also provide statistics on the number of cabinet warning signs, unlocking time, personnel authorization and other information. It can also provide abnormal alarm prompts such as wrong access card swipe, unauthorized intrusion of door locks, device failure, communication interruption, low battery and so on.

[0096] The wireless signal transmitter is used to send the backend terminal instructions to the display device and smart lock for execution, and feed back the collected device status to the backend terminal. It adopts the mature Bluetooth or 2.4GHz local area short-range wireless communication transmission with low power consumption and low electromagnetic interference. The following is the signal transmission process from the backend terminal to the display device: First, the instruction is generated. The backend terminal receives information from user input or other data sources (such as databases, sensors, etc.). The terminal processes the input information according to logic and needs and generates instructions to be sent. These instructions can include text, images or other information formats. The instructions are converted into a format suitable for wireless transmission. Usually a specific encoding protocol (such as JSON, XML, etc.) is used. In order to save bandwidth, the data may be compressed. Then, a suitable wireless communication protocol is selected, such as Wi-Fi, Bluetooth, Zigbee, etc. The selection of different protocols will affect the transmission distance, speed and energy consumption. The wireless signal transmitter sends the encoded instructions through wireless signals. The display device is equipped with a wireless receiving module that can capture the transmitted signal. The receiving module decodes the received signal and converts it back to the original instruction format. The decoded instruction is transmitted to the processing unit of the display device. The processing unit of the display device will render the corresponding content according to the instruction and display it on the screen.

[0097] Distributed display devices are arranged on the front and rear doors of each group of equipment cabinets. Each display device is an independent unit, using ultra-low power consumption color electronic ink screens to reduce maintenance frequency, while meeting color, resolution, backlight, viewing angle, refresh rate and other parameter requirements. Distributed display devices include multiple display screens (such as LED screens, LCD screens, etc.), which can display content independently or synchronously. Distributed display devices usually include one or more controllers for managing and coordinating the content and working status of each display screen. The display devices and the control system are connected through wired or wireless networks to transmit data and instructions. The information content can come from the background database, server, sensor or other data source. Content sources (such as databases, content management systems, sensors, etc.) collect and process data to generate content to be displayed. Then, using content management software, you can select and arrange the information to be displayed, set the time, location and format, and encode the generated content in a specific format (such as JSON, XML, video stream, etc.) for transmission on the network. The content is sent to the control system through an appropriate network protocol (such as HTTP, MQTT, WebSocket, etc.). The control system receives data from the content source; then, according to the layout and needs of the display screen, the data is allocated to different display screens. The control system can realize synchronous display or independent display, and send the processed instructions to each display device through the network. The receiving module of each display device receives the instruction from the control system. The display device renders the content on the screen according to the received instruction to realize information display.

[0098] The smart lock adopts a miniaturized ultra-thin design and matches the device screen cabinet door. It has a mechanical key and a door card dual opening function, and an audio and visual prompt when the built-in battery is low. The door card can be set in the bracelet. The door card uses NFC near-field communication and does not require an additional power supply. The chip is sealed with good waterproof, dustproof, vibration-proof and electromagnetic compatibility, and can be used for a long time in a weak electric field environment. The NFC device generates a radio frequency field through the antenna. When the door card set in the bracelet approaches the smart lock, the door card generates an electromagnetic field. When the door card is close to the smart lock, the electromagnetic field activates the power supply of the smart lock (through electromagnetic induction), enabling it to respond to the door card's request. The door card and the smart lock exchange data through the NFC protocol. This process usually includes: the door card sends a request to the smart lock to inquire about its identity and the information it can provide; the smart lock responds to the request and provides the necessary data; in some cases, the door card needs to confirm the received data. Once the data exchange is completed, the communication between the devices will be automatically interrupted. When the door card leaves the effective range of the smart lock, the communication will stop.

[0099] The system of the backend terminal includes hardware and software. The hardware part includes monitoring equipment, data collectors and computer servers. The monitoring equipment includes temperature and humidity sensors, current sensors, voltage sensors, etc., which are used to monitor the status of the equipment in real time; the data collector is used to upload the monitoring data to the management system; the computer server is used to store and process data and run the management software. The software part includes a management platform and a database. The management platform is used to provide a user interface to facilitate management personnel to view the status of the equipment, conduct data analysis and generate reports; the database is used to store equipment information, historical data, fault records, etc. In addition, the software can use JavaSeript to compile mobile APPs. JavaScript is combined with HTML and CSS in mobile application development to create enterprise management websites. First, create an information architecture diagram of the application, plan the content and functional layout, draw a wireframe diagram, and display the basic layout of each interface to facilitate the operation of smart locks. At the same time, design the user interface (UI) and user experience (UX) to ensure that the APP visual effects are attractive and easy to use, and then use React to build a cross-platform APP that supports iOS and Android; Ionic: Use HTML, CSS and JavaScript to build hybrid applications, suitable for rapid development; Flutter builds high-performance cross-platform applications; design Set up a development environment, including Node.js, npm, and the corresponding development framework, use the CLI tool of the development framework to create a new project, use JavaScript and the corresponding framework to develop the user interface, and build back-end services if necessary. You can use Node.js or other technology stacks, select a suitable database (such as Firebase, MongoDB, etc.), and connect to it; after development, write unit tests for each functional module to ensure its normal operation, test the interaction between modules, ensure the overall function of the system is normal, and invite target users to conduct experience tests and collect feedback; finally, select the release channel (that is, the created corporate website) according to the target platform, use the corresponding packaging tool to package the application, and upload it to the website.

[0100] The system functions of the backend terminal include equipment management, data collection and analysis, maintenance management, alarm and notification, and reports and statistics. The equipment management includes asset management and status monitoring; asset management: recording the basic information of all substation equipment and cabinets, including model, specification, installation location, manufacturer, etc.; status monitoring: real-time monitoring of equipment operation status, such as current, voltage, temperature, humidity, etc., to detect abnormal conditions in time; the data collection and analysis includes data collection and data analysis; data collection: automatic collection of operation data through sensors and monitoring equipment; data analysis: analysis of the collected data to generate equipment operation reports, fault analysis reports and maintenance suggestions; the maintenance management includes maintenance plans and fault recording and processing; Maintenance plan: formulate regular maintenance and overhaul plans, and remind maintenance personnel to perform relevant operations; fault recording and handling: record the time, cause, handling process and results of the fault, and form a complete fault management file; the alarm and notification include real-time alarm and notification mechanism; real-time alarm: when the equipment has abnormal conditions (such as over-limit, fault, etc.), the system can issue an alarm notification in time; notification mechanism: notify relevant personnel through SMS, email, etc. to ensure rapid response; the reports and statistics include report generation and statistical analysis; report generation: regularly generate various reports, including equipment status, maintenance records, fault statistics, etc., to facilitate management decision-making; statistical analysis: analyze equipment failure rate, maintenance cost, etc., to help optimize equipment management.
