DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it can be understood by those skilled in the art that in the embodiments of the present invention, many technical details are provided to enable readers to better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present invention can be implemented.

[0024] Although the monitoring system in the prior art has comprehensive functions and monitored contents, it has certain deficiencies in terms of video monitoring. Since substations generally occupy a large area and volume, monitoring cameras generally need to be deployed in multiple locations to ensure that there are no blind spots. Therefore, the background video display needs to have multiple windows, and each window needs to correspond to a camera. This makes the observer dazzled and unable to intuitively and timely find the area that needs to be observed and understood. The adaptability is poor, and if the camera lens is covered with dust or other impurities, the video will be unclear, thereby affecting the monitoring.

[0025] Embodiment 1:

[0026] The embodiment of the present invention is a three-dimensional monitoring system for a railway substation, characterized by comprising: a plurality of self-cleaning monitoring devices 100 and a monitoring platform arranged at various locations in the substation.

[0027] The self-cleaning monitoring device 100 is communicatively connected to the monitoring platform.

[0028] The monitoring platform includes: a BIM three-dimensional display module 24, a monitoring data projection module 23, a virtual camera module 22 and a monitoring data detection module 21. The BIM three-dimensional display module is used to display the BIM model of the substation. The monitoring data detection module 21 is connected to each of the self-cleaning monitoring devices 100 for communication, and is used to obtain the monitoring screens sent back by each of the self-cleaning monitoring devices 100, and to judge the clarity of the monitoring screens. When the clarity of the monitoring screens is less than a preset threshold, a self-cleaning instruction is issued to the self-cleaning monitoring device 100 that provides the monitoring screens. The number of the virtual camera modules 22 corresponds to the number of the self-cleaning monitoring devices 100, and is used to obtain the monitoring screens provided by the corresponding self-cleaning monitoring devices 100. The setting position of each of the virtual camera modules 22 on the BIM model is the same as the actual installation position of the corresponding self-cleaning monitoring device 100. The monitoring data projection module 23 is connected to each of the virtual camera modules 22, and is used to project the monitoring screens obtained by each of the virtual camera modules 11 on the corresponding area of ​​the BIM model.

[0029] The BIM 3D display module includes: a 3D rotation module 26 and a 3D scaling module 25. The 3D rotation module 26 is used to rotate the BIM model to change the display direction of the BIM model. The 3D scaling module 25 is used to scale the BIM model to change the size of the focus area.

[0030] The BIM-based railway substation monitoring system presents the BIM model of the substation by setting a BIM three-dimensional data model in the control system for data presentation of the three-dimensional data module of the substation, and deploying a virtual camera module on the BIM model that is the same as the actual position of the monitoring camera 11. By rotating the three-dimensional rotation module 26 and zooming the three-dimensional zoom module 25, the area of ​​the substation that needs to be observed and understood can be found intuitively and quickly, and the corresponding camera 11 can be selected on the BIM model, which improves efficiency and can also be understood in real time through a mobile terminal. Moreover, the monitoring data detection module 21 in the system can timely discover the camera 11 that affects the video clarity due to dust accumulation, and then timely clean the dusty camera 11 to ensure the safety of the monitored area and avoid monitoring practices caused by insufficient clarity of the monitoring picture due to dust accumulation on the camera 11. The monitoring data detection module 21 in the present application can directly obtain the clarity of each monitoring video, while also taking into account the influence of weather and the clarity of other monitoring videos. When it is found that the clarity of the monitoring video has not changed much after cleaning, and the outside weather is foggy or light rain, etc., which may affect the monitoring screen, the self-cleaning monitoring device 100 will no longer be controlled to perform self-cleaning operations.

[0031] In some embodiments, the self-cleaning monitoring device 100 includes: a camera 11, a protective cover 12, a self-cleaning component, a mounting bracket 13 and a control module.

[0032] The control module is connected to the monitoring data detection module 21, and is used to control the self-cleaning component to clean the lens 111 according to the self-cleaning instruction of the monitoring data detection module 21. The shield 12 is installed on the top of the camera 11 and is rotatably connected to the camera 11. The mounting frame 13 is rotatably connected to the shield 12, and is used to fix the self-cleaning monitoring device 100 at a specified position. A first motor 121 is arranged between the mounting frame 13 and the shield 12, and the first motor 121 is used to control the horizontal rotation of the camera 11. A second motor 123 is arranged between the shield 12 and the camera 11, and the second motor 123 is used to control the vertical rotation of the camera 11. The first motor 121 and the second motor 123 are both electrically connected to the control module.

[0033] In the present application, the presence of the first motor 121 and the second motor 123 enables the camera 11 to achieve all-round monitoring, thereby ensuring the monitoring effect.

[0034] The self-cleaning component is fixedly mounted on the mounting frame 13, electrically connected to the control module, and is used to clean the lens 111. The self-cleaning component includes a water storage box 14 and a telescopic cleaner.

[0035] The water storage box 14 is fixedly mounted on the top of the mounting frame and is used to store water for cleaning the camera 11. The water storage box 14 includes: a leaking pipe 153, a cover plate 141, an inclined plate 142 and a filter. A cover plate 141 is arranged on the top of the water storage box 14, and one end of the cover plate 141 is aligned with the end of the water storage box 14 close to the lens 111, which is used to prevent foreign matter from entering the water storage box 14. An inclined plate 142 is arranged obliquely on the other end of the top of the water storage box 14, and an overflow port is formed between the inclined plate 142 and the cover plate 141. The inclined plate 142 is used to collect rainwater, and the collected rainwater enters the water storage box 14 through the overflow port. A filter is installed in the overflow port to filter debris. One end of the leaking pipe 153 is connected to the water storage box 14, and the other end is connected to the telescopic cleaner, which is used to pour the water in the water storage box 14 into the telescopic cleaner.

[0036] Since the camera 11 is usually set at a high position, it is difficult to directly add cleaning water to the self-cleaning component of the camera 11, so rainwater is used as cleaning water in this application, so the water storage box 14 in this application needs to involve the collection and storage of rainwater, and the position of rainwater collection prevents foreign matter from entering the water storage box 14 to affect the use of rainwater, so it is necessary to set an inclined plate 142 for rainwater precipitation on the top of the water storage box 14, and the end of the inclined plate 142 away from the cover plate 141 is downward, so that the inclined plate 142 and the water storage box are aligned. 14 forms a temporary water storage area. When the rainwater in the temporary water storage area is full, it will flow into the water storage box 14 through the overflow port. The collected rainwater can have a short sedimentation effect in the temporary water storage area to prevent fallen leaves caused by raindrops or dust attached to the inclined plate 142 from being washed into the water storage box 14 by rainwater. At the same time, in order to prevent impurities floating on the water surface from entering the water storage box 14, a filter net is also set at the overflow port to filter out debris in the rainwater, so as to ensure that the water storage box 14 can discharge water smoothly.

[0037] One end of the telescopic cleaner is connected to one end of the mounting frame close to the lens 111 of the camera 11, and is connected to the water storage box 14 and electrically connected to the control module. The other end of the telescopic cleaner can be freely extended and used to clean the lens 111 with water in the water storage box 14.

[0038] The telescopic cleaner includes a water receiving box 154 , a cleaning plate 152 and a telescopic rod 151 .

[0039] One end of the telescopic rod 151 is fixedly connected to one end of the mounting frame close to the lens 111, and the other end is fixedly connected to one end of the water receiving box 154, and is used to adjust the positional relationship between the telescopic cleaner and the lens 111, and is electrically connected to the control module. The water receiving box 154 is in communication with the water leakage pipe 153, and is used to carry water from the water leakage pipe 153.

[0040] The cleaning plate 152 is a hollow structure, one end of which is connected to the water receiving box 154, and is used to clean the lens 111. The cleaning plate 152 includes: a water outlet hole 1521, a first sponge bar 1522 and a second sponge bar 1523.

[0041] The water outlet hole 1521 is provided on a side of the cleaning plate 152 facing the lens 111. A first sponge bar 1522 is provided at the location of the water outlet hole 1521. The second sponge bar 1523 and the first sponge bar 1522 are both provided on the same side of the cleaning plate 152, and the height of the second sponge bar 1523 is lower than that of the first sponge bar 1522.

[0042] The protective cover 12 is provided with a cleaning groove 122, so that the telescopic cleaner can pass through the cleaning groove 122 to clean the lens 111. A sealing block and a return spring are arranged in the cleaning groove 122. One end of the return spring is connected to the side wall of the protective cover 12, and the other end is connected to the sealing block. One end of the sealing block is rotatably connected to the side wall of the cleaning groove 122, and the other end is in contact with the side wall of the cleaning groove 122.

[0043] The telescopic cleaner in the present application is mainly used to clean the lens 111 of the camera 11. During the cleaning process, considering the complexity of the cleaning action and the stability of the device, the telescopic cleaner is arranged directly above the lens 111, and the lens 111 is cleaned by controlling the up and down movement of the telescopic cleaner. However, at this time, the protective cover 12 will block the telescopic cleaner from cleaning the lens 111, so a cleaning groove for the telescopic cleaner to pass through is provided on the protective cover 12, and a sealing block is provided in the cleaning groove, so that when cleaning is performed, the sealing block will be opened under the push of the telescopic cleaner, so that the cleaning plate 152 can reach the position of the lens 111, and when the cleaning is completed, the cleaning groove 122 can be closed again to reduce the dust accumulation speed on the surface of the lens 111.

[0044] During the cleaning process, rainwater in the water storage box 14 will enter the water receiving box 154 and flow into the cleaning plate 152 through the water pipe. At the same time, the telescopic rod 151 will extend, so that the cleaning plate 152 pushes the sealing block through the cleaning tank 122 to reach the position of the lens 111. The rainwater entering the cleaning plate 152 will pass through the water outlet hole 1521 to soak the first sponge bar 1522. Through the movement of the telescopic rod 151 within a certain range, the first sponge bar 1522 and the second sponge bar 1523 reciprocate to wipe the lens 111. Since the second sponge bar 1523 is installed at a position below the first sponge bar 1522, the second sponge bar 1523 is a dry sponge bar, so the second sponge bar 1523 can clean the water stains on the lens 111. After the cleaning is completed, when the cleaning plate 152 is retracted, the second sponge bar 1523 will wipe the lens 111 for the last time to ensure the cleanliness of the lens 111.

[0045] Moreover, in the present application, the cleaning plate 152 is set as an inverted triangle structure, which makes the process of opening the sealing block easier. When the telescopic cleaner is recovered, the sealing block will press the first sponge bar 1522 and the second sponge bar 1523, so that the dirty water and surface stains in the first sponge bar 1522 and the second sponge bar 1523 are cleared, thereby ensuring the cleaning effect of the first sponge bar 1522 and the second sponge bar 1523.

[0046] Since the camera 11 in the present application can rotate, while the mounting frame cannot rotate, that is, the position of the telescopic cleaner is fixed, in order to ensure that the lens 111 can be well cleaned during cleaning, it is necessary to determine whether the lens 111 has reached the preset cleaning position before cleaning. The determination of whether the cleaning position has been reached can be determined by controlling the rotor positions of the first motor 121 and the second motor 123. Of course, it can also be determined by comparing the shooting picture of the camera 11 to determine whether the camera 11 has reached the preset cleaning position.

[0047] The monitoring system of the present application can solve the problem that the background video display needs to have multiple windows, and each window needs to correspond to a camera. This will cause confusion to the observer, and he will not be able to find the area that needs to be observed and understood intuitively and in a timely manner. The adaptability is poor, and if the camera lens is covered with dust and other impurities, the video will be unclear, thus affecting the monitoring problem. It realizes the simultaneous observation of multiple areas on the BIM model, and can also realize self-cleaning of the camera, thereby ensuring the quality of the monitoring video and improving the security of the monitoring.

[0048] It should be understood that the expressions "mechanism", "device", "component" and the like used in this application are only a method for distinguishing different components, elements, parts, portions or assemblies at different levels. However, if other words can achieve the same purpose, the word can be replaced by other expressions.

[0049] Those skilled in the art can understand that the above-mentioned embodiments are specific examples for realizing the present invention, and in practical applications, the technical features of the above-mentioned embodiments can be arbitrarily combined. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification, and various changes can be made in form and details without departing from the spirit and scope of the present invention.
