Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and in particular to a water level monitoring method, a water level monitoring device, an electronic device, and a storage medium. Background Technology

[0002] There are many factors that affect the construction of urban subway lines. The construction cycle of a subway line is generally 5 to 6 years. It takes a certain amount of time from preliminary planning and feasibility study to the design stage. It also takes a certain amount of time from design to construction. During the construction stage, it is also affected by ground buildings, roads, hydrogeology, funding, etc. Overall, the construction period is very tight. When the communication and signaling system is being constructed, the site environment and building construction are not yet fully completed, and the pipelines and drainage structures are not being used effectively. Once drainage failures or heavy rain occur, water accumulation in the tunnel is very likely to occur.

[0003] The signal system's switch machine equipment is installed in a reserved tunnel pit, which is low-lying and prone to water accumulation. Therefore, when the site environment is harsh, water accumulation in the switch machine pit can be very serious. The switch machine is a critical trackside device in the signal system, used for switching the turnout's position and controlling the train's path. If the water in the pit submerges the switch machine and is not drained in time, it will cause the switch machine to malfunction, making it unable to switch the turnout's position and unable to accurately display the turnout's position status. In severe cases, this can affect train operation safety.

[0004] The existing subway lines do not monitor water accumulation in the switch machine pits, requiring engineers to conduct regular line inspections and use water pumps to remove water. However, visibility in the tunnels is low, and train testing is conducted, significantly impacting personnel safety and on-site operations. The complex on-site environment necessitates periodic inspections; sometimes, the pit is dry immediately after an inspection, but water accumulates later during train testing due to drainage issues, wasting considerable manpower and resources without effectively resolving the problem. Furthermore, submerging the switch machine in water causes equipment damage and high replacement costs.

[0005] A subway line can be tens of kilometers long. If personnel are arranged to patrol it regularly, multiple groups of people are needed. This can lead to staff frustration and affect the efficiency of train testing. In the end, the patrols may fail to find any problems, the switch machines may break down, the testing efficiency may be low, and human, time, and material costs may be wasted.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0039] Figure 1 This is a schematic flowchart of the water level monitoring method provided by the present invention. (Refer to...) Figure 1 The water level monitoring method provided by the present invention includes steps 110, 120 and 130.

[0040] Step 110: Obtain water level monitoring images of the switch machine pit;

[0041] Step 120: Determine the water level value of the switch machine pit based on the water level monitoring image;

[0042] Step 130: If the water level exceeds the alarm threshold, trigger an alarm.

[0043] It should be noted that the executing entity of the water level monitoring method provided by this invention can be an electronic device, a component in an electronic device, an integrated circuit, or a chip. The electronic device can be a mobile electronic device or a non-mobile electronic device. For example, mobile electronic devices can be mobile phones, tablets, laptops, PDAs, in-vehicle electronic devices, wearable devices, ultra-mobile personal computers (UMPCs), netbooks, or personal digital assistants (PDAs), etc., while non-mobile electronic devices can be servers, network-attached storage (NAS), personal computers (PCs), televisions (TVs), ATMs, or self-service machines, etc. This invention does not impose specific limitations.

[0044] The technical solution of this invention will be described in detail below using the example of a computer executing the water level monitoring method provided by this invention.

[0045] In step 110, the water level monitoring image of the switch machine pit can be acquired through the image acquisition device on the outer wall of the switch machine. The water level monitoring image can be image data acquired from the bottom of the pit or from the perimeter of the pit.

[0046] The image acquisition device can be an electronic device with shooting or recording functions. For example, it can include an industrial camera or webcam. Preferably, an image acquisition device suitable for underwater or underground environments can be selected.

[0047] It is understandable that the image acquisition device can acquire water level monitoring images in real time, or it can start acquiring images when the water level in the switch machine pit reaches the warning value; no specific limitation is made here.

[0048] In step 120, the collected water level monitoring images are identified and analyzed to obtain information such as the shooting parameters of the water level monitoring images, the actual scene information of the switch machine pit, or the water level edge line. Based on the above information, the water level value of the switch machine pit can be calculated.

[0049] In step 130, if the water level does not exceed the alarm threshold, the water accumulation in the switch machine pit continues to be monitored.

[0050] The system will automatically sound an alarm if the water level exceeds the alarm threshold, and the alarm can only be turned off after the water accumulation has been cleared.

[0051] The alarm threshold can be set according to actual needs.

[0052] The water level monitoring method provided by this invention can remotely monitor the water level of the switch machine pit by acquiring water level monitoring images of the pit. When the calculated water level reaches a certain level, an alarm is triggered to achieve automatic alarm, thereby ensuring the integrity of the switch machine equipment and eliminating potential traffic hazards.

[0053] In some embodiments, determining the water level of the switch machine pit based on water level monitoring images includes:

[0054] Based on the water level monitoring images, the corresponding shooting parameters for the water level monitoring images are determined. The shooting parameters are automatically adjusted according to changes in water level.

[0055] The water level value is determined based on the shooting parameters.

[0056] In practice, the imaging parameters corresponding to the focal point in the water level monitoring image can be obtained. Since the image acquisition device can adjust the imaging parameters according to changes in water level during the shooting process, the imaging parameter settings corresponding to the focal point in the water level monitoring image are different for different water levels, and different imaging parameters have a mapping relationship with different water levels.

[0057] Shooting parameters may include: lens focal length, magnification, field of view, or image size.

[0058] It is understandable that the mapping relationship between shooting parameters and different water levels can be determined in advance, so that the water level value can be directly determined after the water level monitoring images are collected.

[0059] The water level monitoring method provided by this invention can determine the water level of the switch machine pit in real time, eliminating the need for manpower to inspect the pit and improving the efficiency of water level monitoring.

[0060] In some embodiments, determining the water level value based on the shooting parameters includes:

[0061] Based on preset image algorithms and shooting parameters, the relative distance between the image acquisition device and the water surface corresponding to the water level monitoring image is determined.

[0062] The water level value is determined based on the relative distance.

[0063] In practice, after determining the shooting parameters of the water level monitoring image, a preset image algorithm can be used to determine the relative distance between the image acquisition device and the water surface.

[0064] The preset image algorithm can use a deep learning model, such as the YOLO network model or the U-net convolutional neural network model.

[0065] By inputting the water level monitoring images and corresponding shooting parameters into the trained deep learning model, the relative distance between the image acquisition device and the water surface can be determined.

[0066] After determining the relative distance, the water level in the switch machine pit can be determined based on the location of the image acquisition device.

[0067] The water level monitoring method provided by this invention can determine the water level of the switch machine pit in real time, eliminating the need for manpower to inspect the pit and improving the efficiency of water level monitoring.

[0068] In some embodiments, determining the water level of the switch machine pit based on water level monitoring images includes:

[0069] Based on a preset image algorithm and water level monitoring images, the water level edge line is determined;

[0070] Determine the water level value based on the water level boundary line.

[0071] Understandably, water level monitoring images can directly reflect the water accumulation around the switch machine.

[0072] Based on a preset image algorithm, the water level edge line can be determined in the water level monitoring image. The water level edge line is used to indicate the boundary between the water surface and the pit wall, and can directly reflect the water level value.

[0073] The preset image algorithm can use a deep learning model, such as the YOLO network model or the U-net convolutional neural network model.

[0074] By inputting water level monitoring images into a trained deep learning model, the water level edge line can be determined.

[0075] It should be noted that users can also directly determine the current water accumulation in the switch machine pit based on the water level monitoring images.

[0076] The water level monitoring method provided by this invention can determine the water level of the switch machine pit in real time, eliminating the need for manpower to inspect the pit and improving the efficiency of water level monitoring.

[0077] Figure 2 This is one of the structural schematic diagrams of the water level monitoring device provided by the present invention. (Refer to...) Figure 2 The water level monitoring device provided by the present invention includes: an image sensor 220 and a monitoring terminal 230.

[0078] Image sensor 220 is installed on the bottom of the outer wall of switch machine 210. The image sensor is used to collect water level monitoring images of the switch machine pit.

[0079] The monitoring terminal 230 is communicatively connected to the image sensor 220, and the monitoring terminal is used to display water level monitoring images.

[0080] An image sensor 220 is installed at the bottom of the outer wall of the switch machine 210. The water level monitoring image monitored by the image sensor 220 is transmitted back to the indoor monitoring terminal 230 via cable. The monitoring terminal 230 can open the corresponding interface and click on the corresponding switch machine pit to view the water accumulation situation.

[0081] The image sensor 220 can be an image sensor from different types of cameras. The monitoring terminal 230 can be an electronic device including a display device.

[0082] The monitoring terminal 230 can monitor the water accumulation in the foundation pits of different switch machines, enabling unified management.

[0083] The water level monitoring device provided by this invention can remotely monitor the water level of the switch machine foundation pit, making it convenient for staff to understand the water level of the switch machine foundation pit in real time.

[0084] In some embodiments, the monitoring terminal 230 is also used to receive water level monitoring images sent by the image sensor 220, determine the water level value of the switch machine pit, and determine whether to issue an alarm based on the water level value.

[0085] In actual operation, after receiving the water level monitoring image, the monitoring terminal 230 uses a preset image algorithm to calculate the water level value of the switch machine pit.

[0086] If the water level does not exceed the alarm threshold, the monitoring terminal 230 continues to monitor the water accumulation in the switch machine pit.

[0087] If the water level exceeds the alarm threshold, the monitoring terminal 230 will automatically sound an alarm, which can only be turned off after the water accumulation has been cleared.

[0088] The monitoring terminal 230 can send an alarm to the person responsible for the current switch machine via telephone or send an alarm message to the person's terminal, facilitating timely handling by the person in charge. Alarm methods include, but are not limited to, the implementation methods described above, and are not specifically limited here.

[0089] In some embodiments, the water level in the switch machine pit can be used for graded alarms to further refine the alarm process. The higher the water level, the wider the alarm range and the more personnel can receive the alarm information.

[0090] The water level monitoring device provided by this invention can realize automatic alarm, thereby achieving intelligent water level monitoring.

[0091] In some embodiments, the image sensor 220 may include an infrared camera, and an infrared light source is arranged at the bottom of the pit. The infrared light passes through the water and is acquired by the infrared camera. The light intensity attenuation is obtained through image processing, and the distance through the water is calculated. This distance is then converted into the water level value.

[0092] The water level monitoring method provided by this invention can achieve real-time dynamic water level measurement by utilizing the attenuation of infrared light.

[0093] Figure 3 This is a schematic flowchart illustrating the water level monitoring method using the water level monitoring device provided by the present invention. (Refer to...) Figure 3 The water level monitoring method provided by the present invention includes steps 310, 320, 330, 340, 350 and 360.

[0094] Step 310: The image sensor uploads water level monitoring images to the indoor host unit.

[0095] Step 320: After receiving the water level monitoring image, the host performs image recognition and analysis.

[0096] Step 330: Calculate the water level value of the switch machine pit.

[0097] Step 340: Determine if the water level has reached the alarm point. If it has, proceed to step 350. If it has not reached the alarm point, continue monitoring the water level in the switch machine pit.

[0098] Step 350: Issue relevant alarm prompts.

[0099] Step 360: After the personnel have dealt with the water accumulation in the switch machine pit, they should turn off the alarm.

[0100] This invention, by determining the water level in the switch machine pit in real time, can reduce the equipment damage rate by promptly alerting relevant personnel to handle water accumulation and solving the problem of switch machine damage caused by immersion. It can also save the cost and time of manual inspections, reducing aimless patrols and improving staff efficiency. Furthermore, it can improve driving safety by automatically and accurately alarming to ensure the integrity of the switch machine equipment and eliminate potential driving hazards.
