In recent years, with the rapid growth of my country's social economy and the significant improvement of people's living standards, various power users have put forward higher requirements for the reliability of power supply and distribution and the quality of power supply. As a crucial link in the power system that is directly connected to users and distributes electrical energy to them, the normal and stable operation of the power distribution system directly affects all aspects of people's daily production and life. Therefore, intelligent monitoring of the power distribution system is of great significance. With the continuous development of technology, people's requirements for the manufacturing process of the integrated monitoring device for the power distribution room of a coal preparation plant are also getting higher and higher.

[0003] Existing monitoring devices for coal preparation plant power distribution rooms have certain drawbacks. First, they cannot effectively monitor the power distribution system intelligently, nor can they guarantee its stability, which is detrimental to user experience. Furthermore, the power supply quality in the power distribution room cannot be quickly assessed, reducing the effectiveness of power distribution and negatively impacting actual use. Therefore, we propose an intelligent integrated monitoring device for coal preparation plant power distribution rooms. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an intelligent integrated monitoring device for the power distribution room of a coal preparation plant. Through various sensors, acquisition and communication devices distributed in the power distribution room, it transmits various electrical signals, operating parameters and environmental data to an intelligent operation and maintenance monitoring platform, enabling remote, centralized and real-time monitoring of the user's power distribution room.

It enables remote, centralized, and real-time monitoring of the user's power distribution room, achieving unmanned or minimally staffed operation. When setting up a mobile operation platform for power outage and restoration applications, the mobile management platform should conduct power outage and restoration applications and process monitoring in both the power outage / restoration unit and its WeChat enterprise account. This operation platform requires not only application through the unit's mobile WeChat enterprise account, but also allows the power outage / restoration application unit to contact the dispatcher via telephone or other means, ensuring that the dispatcher can write the power outage / restoration application on the dispatch approval host computer.

[0017] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0018] like Figure 1-4 As shown, an intelligent coal preparation plant power distribution room integrated monitoring device includes a monitoring host 5, a fiber optic ring network mechanism 3, and an integrated monitoring device 1. The integrated monitoring device 1 is connected to a switch 2 and a bus 6. The switch 2 is installed on the fiber optic ring network mechanism 3, and multiple sets of switches 2 are installed. The fiber optic ring network mechanism 3 is connected to a core switch 4, which is connected to the monitoring host 5. The bus 6 is connected to a remote power outage and restoration mechanism 7, an intelligent power outage and restoration management mechanism 8, an environmental monitoring and sensing mechanism 9, an intelligent access control mechanism 10, and an inspection robot mechanism 11. Through various sensors, acquisition and communication devices distributed in the power distribution room, various electrical signals, operating parameters, and environmental data are transmitted to the intelligent operation and maintenance monitoring platform to remotely, centrally, and in real time monitor the user's power distribution room, realizing unmanned or minimally staffed operation of the power distribution room.

[0019] One end of the environmental monitoring sensor mechanism 9 is connected to a temperature sensor 13, a humidity sensor 14, a smoke sensor 15, an illegal intrusion detector 16, and a water leakage detector 17, and the other end of the environmental monitoring sensor mechanism 9 is connected to a fan control box 12.

[0020] The intelligent access control mechanism 10 is connected to a meter recognition monitor 18, a thermal imaging monitor 19, and an image recognition monitor 20.

[0021] The input terminal of the environmental monitoring sensor 9 is electrically connected to the output terminals of the temperature sensor 13, humidity sensor 14, smoke sensor 15, illegal intrusion detector 16, and water leakage detector 17, and the output terminal of the environmental monitoring sensor 9 is electrically connected to the input terminal of the fan control box 12.

[0022] The intelligent access control mechanism 10 is bidirectionally electrically connected to the meter identification monitor 18, the thermal imaging monitor 19, and the image recognition monitor 20.

[0023] The output terminals of the remote power outage and restoration mechanism 7, the intelligent power outage and restoration management mechanism 8, the environmental monitoring and sensing mechanism 9, the intelligent access control mechanism 10, and the inspection robot mechanism 11 transmit data to the integrated monitoring equipment 1 via the bus 6. The monitoring host 5 is connected to the integrated monitoring equipment 1 via the core switch 4, the fiber optic ring network mechanism 3, and the switch 2.

[0024] Example:

[0025] By monitoring various parameters, the on / off status of each distribution circuit, and relevant fault and alarm signals in real time, the intelligent power supply system of the coal preparation plant can be monitored online. This allows for timely notification of power distribution room management personnel to eliminate potential hazards and ensure electrical safety during unattended operation. It has the following functions:

[0026] The host computer interface should display the energized status of the power distribution cabinet unit; alarm signals collected by the integrated protection system should be displayed in a pop-up window when activated; current data of each device should be displayed in real time on the system diagram, and historical curves should be generated on a separate screen; a current report should be generated daily at a specified time (the time can be set); a remote / local switching function button should be provided. After the power outage application, approval, and execution process is completed, an electronic power outage application form should be automatically generated (including time, device name and number, applicant unit and personnel, approving unit and personnel, executing unit and personnel, reason for power outage application, etc.); after the host computer executes the power outage, feedback should be provided to the applicant, approver, and dispatcher's host computers; the de-energized equipment on the system diagram should have a tagging function, and multiple applicant units should apply for power outages, with the number of tags displayed. Power restoration can only be performed after all applicant units have applied for power restoration and all power outage tags have been removed.

[0027] Develop mobile and PC-based power outage and restoration management software to truly achieve paperless office operations for power outage and restoration processes, thereby improving efficiency and safety.

[0028] High and low voltage power distribution rooms should be unattended and equipped with temperature, humidity, and smoke monitoring and control systems.

[0029] It has basic functions such as measurement accumulation, statistical analysis, and automatic reporting.

[0030] The online current interruption procedure is designed as follows:

[0031] Request a power outage

[0032] Applicants for power outages fill out a power outage application form via a mobile app. When applying for a power outage, identity verification is required via facial recognition. A second facial recognition verification is performed when applying for power restoration to ensure consistency between the applicants and prevent production or electromechanical accidents caused by erroneous power restoration applications.

[0033] The system supports various types of power outage and restoration applications, including normal maintenance outages and restorations, temporary maintenance outages and restorations, high-voltage outages and restorations, long-term outages and restorations, and outsourced outages and restorations. The processing procedures differ for different types of power outages and restorations, and these procedures can be configured in the system's backend management module to meet specific business needs.

[0034] The system supports automatic identification of upstream and downstream related equipment for power outage requests, avoiding omissions in power outage and restoration work for related equipment due to human error.

[0035] Dispatch Approval

[0036] After a power outage application is submitted, the system automatically sends an application message to the dispatcher, reminding them to approve it promptly. The system provides dispatchers with a web-based power outage / restoration application approval function. The web interface displays comprehensive information about the application, including equipment information, related equipment information, affected systems, outage maintenance information, and outage / restoration time. If the outage / restoration type is high-voltage, it will also display the high-voltage ticket information and its approval status; unapproved high-voltage tickets cannot be approved for power outage / restoration. Dispatchers can filter and approve power outage applications by system, equipment, or ticket number. When a dispatcher performs an approval action, the system automatically communicates with the equipment's PLC module to obtain real-time equipment status information. Approval is only granted when the equipment is stopped and in its local state; for equipment in operation, the system automatically intercepts the dispatcher's approval action.

[0037] Power outage

[0038] Once a power outage / restoration request is approved by the dispatcher, regardless of whether it involves the main equipment or related equipment, the system will automatically send a power outage task reminder to the electrician on a per-equipment basis. If the dispatcher approves multiple power outage / restoration requests related to the same equipment at the same time, the system will only send a power outage / restoration task reminder to the electrician once. The electrician will then carry out the power outage work according to the task, preventing work chaos caused by multiple requests for equipment power outages.

[0039] Electricians can perform power-off operations on equipment in the corresponding power distribution room based on task prompts. The power distribution room is connected to an external access control system and an internal video surveillance system. Electricians must enter the power distribution room via facial recognition; unauthorized personnel are not allowed entry, ensuring the safety of the power distribution room. The system automatically records access control information and allows for real-time viewing of video surveillance data for easy tracking and investigation.

[0040] After entering the power distribution room, electricians can view the current power outage and restoration tasks on the touch-screen management platform. The platform intuitively displays the distribution cabinets where the power is being cut off and the operating status of the equipment. After performing a power-off operation, the electrician must confirm the power outage on the touch-screen terminal or via a mobile app. Facial recognition verification is required for power outage confirmation to ensure the reliability of power outage and restoration records. Simultaneously, the system automatically detects the PLC status of the equipment; power outage confirmation is not permitted if the equipment is not powered off, preventing safety hazards caused by electrician misoperation.

[0041] Electricity testing

[0042] After a power outage, the system automatically sends a power outage notification to the applicant, reminding them to verify and inspect the equipment. The applicant can confirm the verification via a mobile app. During verification, the applicant can view video monitoring of the control switches in the power distribution room via their mobile phone for secondary confirmation. After verification, the system automatically adds an electronic lock to the equipment being tested, and the electrician can view the number of locks on the touch terminal in the power distribution room. Electronic locks are a crucial factor in ensuring safe power supply.

[0043] Overhaul

[0044] After the power outage applicant completes the power verification, the system automatically sends a reminder to the construction participants to start the maintenance, ensuring that the maintenance work starts in a timely manner, saving time and costs, and improving personnel efficiency.

[0045] Request power supply / test run

[0046] After maintenance is completed, the applicant for power outage must apply for power restoration or test run via a mobile app. During the application process, facial recognition verification is required to confirm that the applicant matches the applicant for power restoration, ensuring operational safety. After the power restoration or test run application is submitted, the system automatically reduces the number of electronic locks.

[0047] In maintenance work, commissioning is a common but complex process, which may involve multiple commissioning runs and repeated maintenance. The system automatically records the commissioning process, performs automatic business logic judgment on power outage and restoration requests during commissioning, monitors effectively, and accurately pushes outage and restoration tasks. This ensures that all power outage requests for relevant equipment are submitted for power restoration or that power is restored during commissioning, and that power outages are initiated after commissioning. It prevents erroneous execution of power outage and restoration tasks due to human error in missing judgment of requests.

[0048] Electrician energizing

[0049] The system determines the legality of power supply based on the number of electronic locks. When the number of electronic locks is 0, power supply is permitted, and the system automatically sends a power supply task reminder to the electrician. If multiple people simultaneously apply for power supply to the same device, only one power supply task is generated, and only one power supply task reminder is sent. The electrician performs the power supply work according to the task, preventing work chaos caused by multiple applications for device power supply.

[0050] After entering the power distribution room, electricians can view the current power outage and restoration tasks on the touch-screen management platform. The platform intuitively displays the distribution cabinets where the equipment is located and its operating status. After performing a power outage operation, the electrician must confirm the power restoration on the touch-screen terminal or via a mobile app. During power restoration confirmation, facial recognition verification is required to ensure the reliability of power outage and restoration records. Simultaneously, the system automatically detects the PLC status of the equipment; power restoration confirmation is not allowed if the equipment is not energized, preventing safety hazards caused by electrician misoperation.

[0051] Ensure normal high-voltage backend communication and data transmission for lump coal and fine coal, and that current and other data can be communicated to the centralized control system of the coal preparation plant for display. Electricians can view the high-voltage work order online and execute high-voltage power outage and restoration tasks according to the high-voltage operation order.

[0052] Resumption of production

[0053] Once all maintenance work on the equipment is completed, the system automatically sends a completion reminder to the dispatcher. The dispatcher then sets the centralized / local control status of the equipment based on the production tasks and arranges production accordingly.

[0054] Working Principle: This utility model includes an integrated monitoring device 1, a switch 2, a fiber optic ring network mechanism 3, a core switch 4, a monitoring host 5, a bus 6, a remote power outage and restoration mechanism 7, an intelligent power outage and restoration management mechanism 8, an environmental monitoring sensor mechanism 9, an intelligent access control mechanism 10, an inspection robot mechanism 11, a fan control box 12, a temperature sensor 13, a humidity sensor 14, a smoke sensor 15, an illegal intrusion detector 16, a water leakage detector 17, a meter identification detector 18, a thermal imaging detector 19, and an image recognition detector 20. Through various sensors, acquisition and communication devices distributed in the power distribution room, various electrical signals, operating parameters and environmental data are transmitted to the intelligent operation and maintenance monitoring platform to remotely, centrally and in real time monitor the user's power distribution room, realizing unmanned or minimally staffed operation of the power distribution room.

[0055] A remote power outage and restoration system is set up, with an operating structure installed in the power distribution circuit of the low-voltage distribution cabinet, a PLC control substation installed in the power distribution room, and the control substation connected to the centralized control system. At the same time, a host monitoring computer is set up in the dispatch room to realize independent monitoring of the power outage and restoration process.

[0056] Set up an intelligent power outage and restoration management system and develop an intelligent power outage and restoration APP to make the power outage and restoration process more information-based and intelligent, realize the automatic process management of power outage and restoration business, and realize electronic power outage signs, electronic records, and paperless power outage and restoration operations.

[0057] Environmental monitoring sensors are installed in the power distribution room to monitor environmental parameters such as temperature, humidity, smoke, unauthorized intrusion, and water leakage in real time. By setting alarm thresholds, equipment such as fans in the power distribution room will be automatically turned on or off when the temperature or humidity exceeds the set values.

[0058] A smart access control system is set up for the power distribution room. When staff enter the power distribution room, they need to compare their information through facial recognition on a smart terminal. Only authorized personnel can open the power distribution room. At the same time, the facial information collected at the front end is recorded and stored.

[0059] The installation of power distribution room inspection robots replaces the original manual inspection mode, realizing unmanned operation of the low-voltage power distribution room in the coal preparation plant. Through technologies such as meter identification, thermal imaging, and image recognition, it can mutually confirm power outage and restoration operations with the intelligent power outage and restoration system, ensuring the safety of personnel, equipment, and production.

[0060] Remote power outage and restoration system for low-voltage power distribution rooms

[0061] Remote power outage and restoration of high and low voltage switchgear in the power distribution room is an essential part of intelligent operation in coal preparation plants. To achieve remote power outage and restoration of high and low voltage, an operating structure is set up for each circuit of the high and low voltage switchgear, a PLC control substation is set up in the power distribution room and connected to the centralized control system, and a host monitoring computer is set up in the dispatch room to achieve independent monitoring of the power outage and restoration process.

[0062] The remote power outage and restoration system for high and low voltage switchgear mainly includes: back-end platform software and back-end operation terminals installed in the central control room / control room; PLC control modules and electrical operating mechanisms for some power distribution circuits installed in the power distribution room.

[0063] Intelligent power outage and restoration management system

[0064] The intelligent power outage and restoration management system supports the entire process of power outage and restoration, including approval, contact person application, commissioning, and electrical distribution operations. Power outage and restoration management utilizes mobile communication terminals to digitize and intelligently manage the process, achieving automated and streamlined management of power outage and restoration operations, and enabling electronic power outage signs, electronic records, and paperless power outage and restoration work.

[0065] The power outage and restoration management module supports the formulation of intelligent power outage and restoration management logic based on the logical relationships between equipment and production connections, enabling automatic judgment and functional approval, and reducing human error and oversight.

[0066] The specific procedures for power outages and restorations are as follows:

[0067] Applying for a power outage: Applicants for power outages or restorations fill out a power outage application form after facial recognition on a mobile app;

[0068] Dispatch Approval: The system provides dispatchers with a web-based power outage and restoration application approval function. When the dispatcher performs the approval action, the system automatically communicates with the PLC module to obtain the real-time status information of the equipment. The approval can only be approved when the equipment is stopped and in the local state. The system will automatically intercept the approval action for equipment that is in production operation.

[0069] Remote Power Outage / Restoration: After power outage confirmation, the system automatically sends a power outage command to the host computer. After the host computer completes the remote power outage, it sends a command completion receipt back to the system. After the applicant verifies and confirms the power supply online, equipment maintenance work begins. Upon completion of the work, the applicant can apply for power restoration online, and the system automatically sends a power restoration command to the host computer. After the host computer performs the remote control operation, it sends a command completion receipt back to the system, thus completing the power outage / restoration process.

[0070] Power outage for electricians: After the dispatcher approves the power outage / restoration request, the system sends a power outage / restoration task reminder to the electrician. The electrician then proceeds to the corresponding power distribution room to disconnect the equipment according to the task reminder. After the equipment disconnection is completed, the electrician must confirm the power outage using facial recognition on the mobile app.

[0071] Power verification: After a power outage, the system automatically sends a power outage notification to the applicant, reminding them to verify and inspect the equipment. The applicant can confirm the power verification via a mobile app. After verification, the system automatically adds an electronic lock to the equipment to ensure safe power restoration.

[0072] Maintenance: After the power outage applicant completes the power verification, the system automatically sends a reminder to the construction worker to start maintenance, ensuring that maintenance work starts in a timely manner, thereby saving time and improving personnel efficiency.

[0073] Requesting Power Restoration / Test Run: After maintenance is completed, the applicant for power outage must apply for power restoration or test run via the mobile app. During the application process, facial recognition verification is required to confirm that the applicant matches the applicant, ensuring operational safety. After a power restoration or test run application is submitted, the system automatically reduces the number of electronic locks.

[0074] Electrician power supply: The system determines the legality of power supply based on the number of electronic locks. When the number of electronic locks is 0, power supply is permitted. The electrician then performs the power supply work according to the task.

[0075] Production resumption: Once all maintenance work on the equipment is completed, the system automatically sends a completion reminder to the dispatcher. The dispatcher then sets the centralized / local control status of the equipment based on the production tasks and arranges production accordingly.

[0081] The system can determine the current status of the equipment. Before confirming power supply, the system determines whether the equipment meets the conditions for power supply to avoid human error.

[0082] The system verifies the identities of both the power outage applicant and the power restoration applicant to ensure the principle of "whoever cuts the power, restores the power";

[0083] The dispatch confirmation and leadership approval of power outage and restoration application forms can be performed not only through the APP but also through the WEB.

[0084] The system is equipped with an access control system and a video surveillance system, which improves operational safety and allows for effective monitoring of the operational process.

[0085] Power Distribution Room Environmental Monitoring System

[0086] The power distribution room is the power hub of a coal preparation plant. The normal operation of the power distribution system is a prerequisite for ensuring the normal operation of on-site production equipment. Environmental factors in the power distribution room directly determine the operating status of the power distribution system. Therefore, setting up a power distribution room environmental monitoring system can ensure the normal operation of the power distribution system, provide early warnings of abnormal conditions when necessary, and promptly handle abnormal accidents to avoid production losses caused by the escalation of accidents.
