Description

Technical Field

[0001] This invention relates to the field of safety management technology for unattended power plants, and more specifically, to a safety management system for unattended power plants. Background Technology

[0002] With the continuous improvement of industrial automation, unmanned power plants are increasingly widely used in power, water conservancy, and energy sectors. These power plants are typically located in remote and complex environments, and contain various critical equipment such as circuit breakers, water pumps, and fans, making their stable operation crucial. Currently, the management of many power plants still relies on the traditional model of local monitoring combined with regular manual inspections. This model suffers from problems such as slow response times, high labor costs, and the inability to monitor equipment status and environmental parameters in real time.

[0003] While some existing remote management systems have achieved data collection to a certain extent, they generally suffer from the following defects: First, the system integration is low, and each subsystem (such as environmental monitoring, equipment control, and video management) often operates independently, forming "information silos" that are difficult to coordinate and centrally manage. Summary of the Invention

[0004] The purpose of this invention is to provide an unattended power plant safety management system to improve the above-mentioned technical problems.

[0005] To achieve the above objectives, the embodiments of this application provide the following technical solutions: This application provides an unattended power plant safety management system. The system includes: a host computer software module deployed on a remote server, used to centrally manage multiple controller modules and display the real-time operating status of power plant equipment, surrounding environmental data, and abnormal equipment operation information; supporting voice broadcasting, equipment status visualization, alarm mechanisms, and remote desktop access; and multiple controller modules connected to the host computer software module via Ethernet. Responding to data reading commands sent by the host computer software module, these controller modules collect power plant equipment status data and surrounding environmental temperature and humidity data, package them, and transmit them back to the host computer software module. The temperature accuracy is ±1℃, the humidity accuracy is ±5%RH, and the data collection frequency is 2 times / second.

[0010] Optionally, the host computer software module sends a heartbeat packet to the controller module every 30 seconds.

At the same time, the host computer software module's interface displays the offline status.

[0011] Optionally, the input / output interface submodule includes multiple digital input channels and relay output channels. The digital input channels are connected to ambient temperature and humidity sensors and power plant equipment current monitoring sensors, while the relay output channels are connected to circuit breakers, water pumps, and fans to achieve precise control of the switching status of power plant equipment.

[0012] Optionally, the power supply submodule adopts a dual-redundancy design, with the main power supply and the backup power supply connected in parallel through isolation diodes.

[0023] like Figure 1-2 As shown in the figure, this embodiment provides an unattended power plant safety management system, the system including: The host computer software module, deployed on a remote server, is used to centrally manage multiple controller modules and display the real-time operating status of power plant equipment, data of the surrounding environment of the power plant, and abnormal equipment operation information. It supports voice broadcast, equipment status visualization, alarm mechanism, and remote desktop jump. Multiple controller modules are connected to the host computer software module via Ethernet. In response to the data reading command sent by the host computer software module, they collect power station equipment status data and ambient temperature and humidity data of the power station, and package and transmit them back to the host computer software module. The temperature accuracy is ±1℃, the humidity accuracy is ±5%RH, and the acquisition frequency is 2 times / second. The controller module includes: The main control submodule is used for data processing, logic control and command sending. It adopts the domestic GD32 microcontroller to ensure system stability. The communication submodule includes an RS485 communication interface, two Ethernet communication interfaces, and a USB interface, enabling the main control submodule to establish data transmission links with the power station equipment, the TTS voice module, the IPKVM submodule, and the host computer software. The RS485 communication interface in the communication submodule is used to establish a data transmission link between the main control submodule and the TTS voice module, and the Ethernet communication interface in the communication submodule is used to build a data transmission link between the main control submodule and the host computer software.

[0024] The input / output interface submodule is configured on the main control submodule and connects to environmental monitoring sensors, equipment status sensors and control actuators to realize real-time monitoring and control of power plant equipment. It supports 8 channels of analog / digital input / output. The power plant equipment includes circuit breakers, water pumps, fans, environmental monitoring equipment and security alarm devices. The IPKVM submodule includes two HDMI ports and one USB port, which connect to the power plant's industrial control computer and connect to the Ethernet communication interface. Through IP-based KVM, it integrates remote management of the keyboard, video, and mouse, thereby enabling remote display of the power plant's industrial control computer's operating desktop and supporting synchronous control of the mouse and keyboard.

[0025] Secondly, in this embodiment, the controller module also includes a power supply submodule, which provides multiple regulated outputs, integrates overvoltage protection and external isolation functions, and ensures that the controller module is stably powered in complex environments.

[0026] When the host computer software module sends equipment control commands, the controller module parses the commands and drives the specified power station equipment through the input / output interface submodule. When abnormal device operation information is detected, the controller module packages the abnormal device operation information and sends it to the host computer software module, so that the host computer software module triggers the pop-up prompt and voice broadcast process, and the host computer software module sends voice commands to the TTS voice module for broadcast.

[0027] Secondly, the host computer software module sends a heartbeat packet to the controller module every 30 seconds. If there is no response for a total of 3 times, the controller module is determined to be offline and a reconnection mechanism is triggered. At the same time, the host computer software module's interface displays the offline status. The heartbeat packet mechanism includes dynamic timeout threshold adjustment, optimizing the heartbeat interval based on historical network latency data, reducing the false judgment rate, and improving the stability of the communication link.

[0028] The input / output interface submodule includes multiple digital input channels and relay output channels. The digital input channels are connected to environmental temperature and humidity sensors and power plant equipment current monitoring sensors, while the relay output channels are connected to circuit breakers, water pumps, and fans to achieve precise control of the switching status of power plant equipment.

[0029] The power supply submodule adopts a dual-redundancy design, with the main power supply and the backup power supply connected in parallel through isolation diodes. When the main power supply fails, it automatically switches to the backup power supply to ensure uninterrupted operation of the controller.

[0030] The host computer software module integrates equipment fault early warning function. By analyzing equipment power consumption data and running time, it predicts potential faults and generates maintenance plans to reduce the risk of equipment downtime. The main control submodule has a built-in data cache area for temporarily storing environmental data and device status data. It maintains local data processing capabilities when the network is interrupted and synchronizes the data to the host computer software after communication is restored.

[0031] This embodiment provides an unattended power plant safety management system that, through the collaboration of the host computer software module and the distributed controller module, unifies the status of dispersed power plant equipment, environmental parameters, and abnormal information to a remote central platform and displays them in real time with a visual interface. This completely breaks down "information silos," enabling managers to have a comprehensive and intuitive grasp of the entire operation of the power plant and greatly improving management efficiency. Secondly, the system uses Ethernet as the backbone, combined with multi-interface communication submodules such as RS485, ensuring the diversity and stability of data transmission. Its unique dynamic heartbeat and reconnection mechanisms effectively cope with network fluctuations, reduce false alarm rates, and guarantee uninterrupted and reliable transmission of control commands and status data, laying a solid foundation for remote and precise control.

[0032] The system's integrated equipment fault early warning function, by analyzing equipment power consumption and runtime data, can predict potential faults in advance and generate maintenance plans, transforming passive maintenance into proactive maintenance and significantly reducing the risk of equipment downtime. Meanwhile, the data buffer design of the main control submodule and the dual-redundancy automatic switching design of the power supply submodule jointly ensure that the system's local processing and control functions remain uninterrupted in abnormal situations such as network interruptions or main power failures, greatly enhancing the system's robustness in complex environments.

[0033] The input / output interface submodule, configured on the main control submodule, connects to environmental monitoring sensors, equipment status sensors, and control actuators to achieve real-time monitoring and control of the power plant equipment, including: The power station equipment includes an electric fence installed at the power station gate. The environmental monitoring sensors include a first camera and a second camera installed at the power station gate. When an abnormal vehicle is detected approaching the power station gate, the controller module packages the lane information at the power station gate and sends it to the host computer software module. This causes the host computer software module to trigger a pop-up prompt and voice broadcast process. The host computer software module then sends a voice command to the TTS voice module for broadcast. The specific implementation method can be as follows: When a vehicle approaches, a preset shape-based image recognition algorithm is used to detect the fixed area (license plate hanging area) of the target vehicle and check whether the vehicle has a license plate. If it does not exist, the power station-specific temporary license plate detection process is initiated, and the temporary license plate detection process is announced to the driver via a TTS voice module. At the same time, the power station-specific temporary license plate information and vehicle color information are obtained through the first camera and the second camera, respectively, and the consistency between the power station-specific temporary license plate and the vehicle color information is compared. If they are inconsistent, the entry video corresponding to the current vehicle is retrieved, and the video of the target vehicle from the first preset position to the second preset position is captured and recorded as the first video. The video is divided into multiple time points based on the average duration of the first video. The consistency between the vehicle color information and the temporary license plate information in each video screenshot is evaluated, and a consistency score is calculated using a weighted algorithm. If the consistency score is passed, the gate opening operation is executed.

[0034] Among them, ensuring the consistency between the specific temporary license plate of the power station and the vehicle color information includes: retrieving the vehicle's registration information based on the temporary license plate information, wherein the registration information includes the vehicle's color information, and setting a corresponding first RGB range threshold based on the color information; The system detects the area ratio of the region whose color value is within the first RGB range threshold in the vehicle color information, calculates a consistency estimate based on the area ratio, and determines that the vehicle color information and temporary license plate information are inconsistent if the consistency estimate is less than a preset threshold.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
