Description

Technical Field

[0001] The invention relates to the technical field of adding multiple sensors to all-weather hidden danger monitoring of power transmission lines, and in particular to an online monitoring device for power transmission icing with an integrated tension sensor. Background Art

[0002] Existing online monitoring equipment for power transmission icing generally uses images to take pictures of icing on transmission lines and then performs image analysis on the obtained images to obtain the approximate thickness of the icing. Some online icing detection products integrate a single tension sensor device to detect the thickness of the icing. Independent meteorological sensors are used to predict the environmental climate to obtain the icing conditions, and then other sensors are linked for confirmation. Online monitoring equipment for power transmission icing relies on image analysis methods, which has poor accuracy and cannot obtain accurate icing values. However, in the prior art, image equipment is easily covered with ice during the icing season, resulting in the inability to take pictures normally, making it impossible to obtain effective information through image analysis methods. Simply using the number of tension sensors to judge the thickness of the icing may result in the possibility of misjudgment. Independent installation of image monitoring equipment and multi-factor meteorological sensors is complex and costly. Summary of the invention

[0003] In view of this, an object of the present invention is to provide an online monitoring device for power transmission icing with an integrated tension sensor to improve the accuracy of icing values.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an online monitoring device for power transmission icing with an integrated tension sensor, comprising a main control module, a tension sensor module, a micro-meteorological sensor module, an image monitoring module and a power supply module; the micro-meteorological sensor module is connected to the main control module via a wired interface to provide the main control module with real-time external environmental meteorological information; the tension sensor communicates with the main control module via a wireless transmission interface to provide the main control module with accurate wire tension information, and the main control module accurately converts this information into icing thickness information; the image monitoring module comprises a daytime camera module and a night vision camera group to provide the main control module with effective and accurate image information; the main control module is provided with a heated glass and a wiper device; when icing occurs, the main control module controls the heating of the heated glass, and the wiper device washes the generated water.

[0005] In a preferred embodiment, the daytime camera module adopts a high-pixel, small-aperture module for daytime photography and video information collection.

[0006] In a preferred embodiment, the night vision camera group uses a large aperture and large target area sensor module to monitor the line in a dark light scene.

[0007] In a preferred embodiment, the micro-meteorological sensor module includes a housing assembly, a wind direction and speed sensor, a rainfall sensor, and a light radiation sensor.

[0008] In a preferred embodiment, the wind direction and speed sensor, the rainfall sensor and the optical radiation sensor are placed in the housing assembly.

[0009] In a preferred embodiment, the main control module acquires meteorological data, tension sensor and image information in a time-sharing manner, analyzes the three information, and when abnormal meteorological conditions occur, determines the type of abnormal weather. The main control module links the image monitoring module to collect images, and performs image analysis on the taken pictures to determine whether there are hidden dangers and the types of hidden dangers. If there are hidden dangers, the pictures with hidden dangers are uploaded to the monitoring platform and an alarm is issued, so that the monitoring personnel can view and handle them; if there are no hidden dangers, the pictures with meteorological information are uploaded to the monitoring platform for storage. If it is confirmed that it is abnormal icing weather, the tension sensor data information is collected at the same time, compared with the correct value, and the ice coverage value of the wire at that time is calculated. If the data is confirmed to exceed the set threshold value, the main control reports to the platform and an alarm is issued.

[0010] In a preferred embodiment, the main control module and the micro-meteorological sensor module communicate using RS-485.

[0011] In a preferred embodiment, the main control module and the image monitoring module communicate using IIC.

[0012] In a preferred embodiment, the main control module communicates with the tension sensor via a wireless protocol.

[0013] In a preferred embodiment, the power module uses a photovoltaic panel and a lithium iron phosphate rechargeable battery.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The host uses the integrated micro-meteorological sensor to predict the icing environment after receiving the information from the micro-meteorological sensor, thereby working in conjunction with the tension sensor and image sensor. The prediction is not made through a single sensor. The integrated tension sensor can accurately obtain the ice thickness value. The anti-icing design of the image sensor can obtain clear images in real time even in the icing season. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] refer to Figure 1-5 The power transmission icing online monitoring device with integrated tension sensor integrates: tension sensor, micro-meteorological sensor, image monitoring module, power module and main control module. The multi-factor meteorological sensor device is connected to the host through a wired interface to provide the host with real-time external environmental meteorological information; the tension sensor uses a wireless transmission interface to communicate with the host, providing the host with accurate wire tension information, and the host can accurately convert this information into ice thickness information; the image monitoring module uses two specifications of camera modules, daytime + night vision, which can meet the host's all-weather real-time image transmission and provide the host with effective and accurate image information; the power module is a photovoltaic panel + rechargeable battery to provide the host with necessary working energy; the lens of the host is heated glass, and it is also equipped with a wiper device. When the host lens is covered with ice, the lens can be de-iced in time to ensure the effectiveness of the host's photography; in addition, the housing above the host lens adopts a brimless design to ensure that the liquid actively flows down when the ice and snow melt, reducing adhesion on the periphery of the lens; the equipment integrates tension sensor monitoring, micro-meteorological monitoring, and image acquisition, which can realize multi-information integrated monitoring, data visualization, and equipment linkage, and through the linkage between modules, timely judgment and alarm are made when abnormal icing weather that threatens the safety of the line occurs.

[0020] The power module supplies power to the main control module, multi-factor meteorological sensor, and image monitoring module; The tension sensor module is powered separately; The main control module allocates power supply time periods according to monitoring requirements; the main control module communicates with the multi-element meteorological sensor using RS-485, communicates with the image module using IIC, communicates with the monitoring platform using 4G, and communicates with the tension sensor through wireless protocol; controls the linkage of the tension sensor, multi-element meteorological sensor and image monitoring module; The tension sensor includes: a sensor body, a power module, and a communication module; The power module uses photovoltaic panels + lithium iron phosphate rechargeable batteries to provide the tension sensor with the energy required for operation; The sensor body accurately measures the line tension; Communication module The multi-factor meteorological monitoring module includes a shell assembly, a wind direction and speed sensor, a rainfall sensor, and a light radiation sensor.

[0021] When the ambient weather conditions reach the point where the camera in the image monitoring module fogs up, the main control module turns on the defog mode (turns on the lens heating and the wipers at the same time) to ensure the reliability of the image monitoring module.

[0022] When the weather information reaches the freezing conditions, the main control module actively turns on the lens heating component to prevent the host lens component from being covered with ice, resulting in invalid information when taking photos.

[0023] The image monitoring module includes a first camera component and a second camera component. The first camera adopts a high-pixel, small-aperture module for taking photos and collecting video information during the day; the second camera component adopts a large-aperture, large-target sensor module to monitor the line in dark light scenes.

[0024] The main control module obtains meteorological data, tension sensor and image information in a time-sharing manner, analyzes the three information, and when abnormal meteorological conditions (low temperature, high temperature, ice and snow, fog, etc.) occur, the type of abnormal weather is determined. The main control module links the image monitoring module to collect images and analyze the taken pictures to determine whether there are any hidden dangers and the types of hidden dangers. If there are hidden dangers, the pictures with hidden dangers will be uploaded to the monitoring platform and an alarm will be issued for the monitoring personnel to view and handle them. If there are no hidden dangers, the pictures with meteorological information will be uploaded to the monitoring platform for storage. If it is confirmed to be abnormal icing weather, the tension sensor data information should be collected at the same time, compared with the correct value, and the ice coverage value of the wire at that time should be calculated. If the data is confirmed to exceed the set threshold value, the main control will report to the platform and issue an alarm.
