[0061] In the embodiment, the power device and the controller are embedded in the main body, so that the track industrial robot has the ability of independent operation, and the self-sufficiency of the system is improved. The power device can be adjusted by the controller, or the upper computer control platform can control and adjust the power device through the controller, so as to ensure the stable operation of the track industrial robot. The track industrial robot integrates the image acquisition assembly and the alarm device on the mounting platform, reduces the demand for other external devices, and enhances the independent working ability of the robot. The upper computer control platform in the embodiment is connected with the signals of the sensor equipment, the image acquisition assembly, the track robot monitoring device and the like, so as to ensure the smoothness and timeliness of information transmission. Through the control platform, the user can view the device state and the monitoring picture in real time, and receive the alarm information, so as to avoid information transmission delay or loss.

[0062] Specifically, the sensor equipment 2 includes a temperature sensor, a gas sensor, a smoke sensor, a humidity sensor, and a micro-vibration sensor arranged on a pipeline in the thermal power plant. In the embodiment, the sensor equipment 2 includes multiple sensors, so that the system can comprehensively monitor various environments and device states in the thermal power plant, covers multiple monitoring dimensions such as temperature, gas, humidity, vibration, and can timely discover and prewarn device abnormalities, environmental changes or potential dangers (such as fire, gas leakage and the like).

[0063] In the actual application of the embodiment, the high-definition camera assembly 3 includes multiple high-definition cameras, multiple dual-spectrum imaging devices and multiple low-light cameras arranged in the thermal power plant.

[0064] Each high-definition camera, each dual-spectrum imaging device and each low-light camera are connected with the upper computer control platform 1.

[0065] All high-definition cameras, dual-spectrum imaging devices and low-light cameras in this embodiment are connected with the upper computer control platform 1, realizing data transmission and integration. Through such hardware connection, the data of all devices can be centrally collected and managed, greatly improving the efficiency of data processing. After real-time image information is transmitted to the upper computer control platform, it can be displayed, analyzed and processed, so that the monitoring personnel can view real-time video from different areas through the display device. Moreover, various camera devices are connected to the upper computer control platform, so that the monitoring system has the functions of centralized management and unified control. Through the upper computer control platform, users can easily retrieve data of different camera devices, switch camera angles, set device parameters, etc., which makes monitoring more convenient and efficient. Through integrated hardware connection, the system can display multiple monitoring angles on a unified operation interface, which is convenient for users to view in real time. At the same time, the use of multiple types of camera devices (high-definition, dual-spectrum, low-light) can ensure that the monitoring system can function in various environmental conditions.

[0066] In this embodiment, the first alarm device 6 includes M audible and visual alarms and N voice alarms.

[0067] Wherein, M is greater than or equal to 1, and N is greater than or equal to 1.

[0068] Specifically, through the setting of M audible and visual alarms and N voice alarms, the actual situation of the factory area can be flexibly arranged.

[0069] In this embodiment, the image acquisition assembly 44 includes an intelligent pan-tilt, a super-definition camera and a multi-degree-of-freedom transformation shaft. The super-definition camera is arranged at the upper part of the intelligent pan-tilt, and the intelligent pan-tilt is installed on the mounting platform through the multi-degree-of-freedom transformation shaft. The linkage of the intelligent pan-tilt and the multi-degree-of-freedom transformation shaft can be adjusted through a centralized control signal. This hardware connection method enables the system to quickly adjust the angle of view of the camera according to actual needs, and remotely operates through the upper computer control platform, reducing manual intervention. Especially, the multi-degree-of-freedom transformation shaft can provide more accurate positioning, ensuring that the camera obtains the most ideal image acquisition angle.

[0070] Since the camera can freely rotate and tilt through the pan-tilt and the transformation shaft, the system can realize 360-degree omnidirectional monitoring, reducing the blind area or dead angle problem between devices. Such hardware connection relationship makes the image acquisition system have stronger adaptability, which can effectively monitor different areas and obtain comprehensive monitoring information.

[0071] In this embodiment, the second alarm device 45 is a voice alarm.

[0072] Specifically, the surface of the work site track 42, the mounting platform, the sensor device 2, and the high-definition camera assembly 3 is provided with an anti-corrosion coating.

[0073] The anti-corrosion coating is an epoxy resin coating.

[0074] In this embodiment, the surfaces of the work site track, the mounting platform, the sensor device, and the high-definition camera assembly are coated with epoxy resin, which can effectively prevent these hardware from being corroded and causing problems such as loose connection or poor contact during long-term operation. In particular, for electrical connection parts, corrosion can cause signal interference, current interruption, or equipment damage, and the anti-corrosion coating effectively prevents these problems from occurring.

[0075] In this embodiment, the display device 5 is connected in communication with the upper computer control platform 1 through HDMI and RS-232 interfaces.

[0076] The display device 5 is a touch display.

[0077] In this embodiment, the HDMI interface has high bandwidth and high-definition video transmission capability, enabling the display device to stably and clearly display image content, meeting the high-definition display requirements. On the other hand, the RS-232 interface, as a low-speed and reliable serial communication protocol, can provide stable data transmission, especially in cases of high interference or long distances, ensuring stable signal transmission. The two interfaces complement each other, improving the flexibility and reliability of hardware connection.

[0078] Preferably, referring to Figure 3 , the system further comprises a positioning and navigation system 7; the positioning and navigation system 7 comprises a laser radar and an ultrasonic sensor mounted on the mounting platform of the track-type industrial robot 41; the laser radar and the ultrasonic sensor are connected with the controller 43 through CAN bus interfaces respectively.

[0079] In this embodiment, the laser radar and the ultrasonic sensor are integrated in the track-type industrial robot and connected through the CAN bus interface, which not only improves the navigation and positioning accuracy of the system, but also ensures the reliability and expandability of the hardware. This structure enables the system to work efficiently and flexibly in complex working conditions, while simplifying data transmission through the CAN bus interface, improving the stability and reliability of the system, and enhancing the safety and efficiency of the robot in industrial environments.

[0080] In the practical application of this embodiment, the number of high-definition cameras is 4; M is 4 and N is 2; the thickness of the anti-corrosion coating is 150 microns; and the dual-spectrum imaging device is a dual-spectrum thermal imaging camera.

[0081] In this embodiment, the configuration of 4 high-definition cameras can provide more comprehensive monitoring angles for the power plant. Each camera can cover different areas, ensuring no dead angle monitoring, real-time grasp of the operation status inside the plant, especially the monitoring of key equipment and important areas, which can quickly discover potential safety hazards or fault points.

[0082] The configuration of the sound and light alarm and the voice alarm can provide different alarm modes according to the situation. The sound and light alarm is used to attract the attention of the on-site personnel, while the voice alarm can provide more specific warning information (such as equipment failure, fire alarm, etc.). The diverse alarm forms can ensure that the operating personnel can timely receive warning information whether in a noisy environment or at a distance.

[0083] In such a harsh environment as a thermal power plant, the application of anti-corrosion coating is crucial. The coating thickness of 150 microns means that it has strong protective effect and can effectively prevent the surface of the equipment from being oxidized, corroded and worn. The moderately thick anti-corrosion coating helps to maintain the long-term stability of the appearance and structure of the equipment, reducing maintenance costs and downtime.

[0084] The dual-spectrum thermal imaging camera can capture visible light and thermal images simultaneously, enabling the system to identify temperature anomalies, fire hazards, and overheating of electrical equipment in normal lighting conditions as well as low-light or no-light environments. This allows timely detection of potential safety hazards and improves the response speed of fire and safety management. The dual-spectrum imaging device makes image acquisition more precise and accurate, enabling real-time temperature distribution monitoring and helping operators quickly locate problem areas, especially for areas with temperature changes such as electrical equipment and pipelines, allowing accurate detection of abnormal conditions.

[0085] The connection of the high-definition camera with the upper computer control platform enables the video signals captured by the camera to be transmitted to the upper computer control platform in real time for processing and monitoring. In this way, operators can view the plant's status in real time through the display device, identify abnormal conditions and respond. The distribution of multiple cameras ensures comprehensive image acquisition and monitoring.

[0086] Through the unified scheduling of the upper computer control platform, multiple cameras can work cooperatively to provide real-time dynamic monitoring, and even through intelligent algorithm analysis of images from different angles, automatic identification and alarm can be achieved, improving monitoring efficiency.

[0087] The power plant centralized control auxiliary early warning system in this embodiment is a physical hardware connection. This embodiment does not involve any improvement and use of computer programs and software technology, but only provides the connection relationship between the devices in the power plant centralized control auxiliary early warning system.

[0088] The industrial robot in the power plant centralized control auxiliary early warning system in the embodiment moves autonomously on the site track and collects data of different areas of the power plant in real time. This mode makes up for the deficiency of the traditional manual inspection. The robot can cover multiple key areas through inspection, reduces the time interval of manual inspection, and improves the real-time performance of data collection. Temperature sensors, humidity sensors, gas sensors, and micro-vibration sensors and other devices acquire temperature, humidity, harmful gas concentration, and equipment vibration conditions in real time. The deployment of these sensors at key positions enables the system to continuously collect equipment operation data for 24 hours, forming comprehensive monitoring covering various operating states. At the same time, high-definition cameras, dual-spectrum imaging devices, and low-light cameras and other multi-type camera devices are configured, which can continuously provide clear pictures in the daytime, at night, and in harsh environments. These devices can monitor the operation of the power plant, monitor the surface temperature of the equipment and environmental changes, and greatly improve the accuracy of fault monitoring of the power plant. The dual-spectrum thermal imaging device can realize real-time detection of the surface temperature of the equipment through infrared thermal imaging, quickly identify the overheating condition of the equipment, and timely discover hidden dangers that may cause equipment failure. The various alarm devices configured can issue sound and light alarms or voice alarms according to specific conditions, and immediately remind the on-site staff when the system detects abnormal temperature, gas, vibration, and other indicators. At the same time, the diversity of the alarm devices ensures that the alarm information can be conveyed in time and effectively even in complex and noisy environments.

[0089] The technical principles of the utility model are described above in combination with specific embodiments, and these descriptions are only for explaining the principles of the utility model and cannot be interpreted in any way as a limitation on the protection scope of the utility model. Based on the explanation here, those skilled in the art can think of other specific embodiments of the utility model without creative labor, and these embodiments will all fall within the protection scope of the utility model.
