Description

Technical Field

[0001] This invention relates to the field of pipeline planning technology in the building design process, and in particular to an intelligent manhole cover and an intelligent manhole cover monitoring system. Background Technology

[0002] Manhole covers are an important component of urban infrastructure, primarily used to cover underground pipes, cables, and other facilities, ensuring road safety and pedestrian passage. Traditional manhole covers are typically made of cast iron, concrete, or composite materials, providing only basic load-bearing and protective functions, lacking intelligent, interactive, and cultural attributes. With the development of smart cities and the cultural tourism industry, the limitations of traditional manhole covers are becoming increasingly apparent. They are only used for physical coverage and cannot be integrated with urban management or visitor interaction.

[0003] In recent years, some smart manhole covers have upgraded their functionality by integrating sensors and communication modules. Examples include: status monitoring: detecting manhole cover displacement or theft using tilt sensors and GPS positioning (such as municipal manhole covers in some Chinese cities); environmental monitoring: equipped with temperature, humidity, and gas sensors for urban environmental data collection; and anti-theft alarms: triggering alarms based on vibration sensors.

[0004] However, existing technologies still have the following problems: Insufficient interactivity: The functions are concentrated on urban management and do not form effective interactions with pedestrians or tourists. Limited triggering methods: Relying on electronic tags (such as QR codes and NFC), users need to actively operate their mobile phones, resulting in a passive experience. Furthermore, since tourist check-ins are only done by scanning QR codes or using NPCs, it cannot be confirmed whether the mobile device associated with the tourist's account is operated by the person in question. This could lead to situations where someone else checks in on behalf of the tourist or where a QR code can be scanned even if the area is not in the corresponding region, thus raising questions about the authenticity of the check-ins. Summary of the Invention

[0005] The purpose of this invention is to provide a smart manhole cover that enhances the authenticity of tourist photo-taking experiences.

[0006] The above-mentioned objective of this invention is achieved through the following technical solution: A smart manhole cover includes: a stepping layer, which is used to detect the weight of objects acting on the stepping layer, generate a stepping weight value, detect pairing information of surrounding mobile devices, and receive one-to-one pairing information and user weight values; when the stepping layer detects that the stepping weight value is close to the user weight value, the stepping layer starts to detect the pairing information of surrounding mobile devices. If there is a pairing information corresponding to the user weight value that is close to the stepping weight value, the stepping layer sends a check-in information to the mobile device corresponding to the pairing information; and a support layer, located below the stepping layer, for supporting the stepping layer.

[0007] The present invention is further configured such that: a prompting component is provided on the stepping layer, the prompting component being used to indicate that the check-in information has been sent to the mobile device.

[0008] The present invention is further configured such that: the prompting component is a ring-shaped light strip, and the ring-shaped light strip is circumferentially disposed at the edge of the stepping layer.

[0009] The present invention is further configured such that: the stepping layer includes a pressure sensor, the pressure sensor is disposed on the bottom surface of the stepping layer, and the pressure sensor is covered with a flexible cover.

[0010] The present invention is further configured such that: the upper end surface of the support layer is provided with a groove for accommodating the pressure sensor.

[0011] The present invention is further configured such that: the bottom surface of the stepping layer is provided with a limiting post, and the supporting layer is provided with a limiting groove that cooperates with the limiting post.

[0012] The present invention is further configured such that: a controller is provided inside the side step layer, the controller including a control module, a remote communication module and a near-end communication module, the control module being connected to the remote communication module and the near-end communication module, the control module being used to acquire the one-to-one matching information and user weight value received by the remote communication module, and when the detected stepping weight value is close to the user weight value, the control module controls the near-end communication module to detect the matching information of surrounding mobile devices, if there is matching information corresponding to the user weight value close to the stepping weight value, the control module controls the near-end communication module to send check-in information to the mobile device corresponding to the matching information.

[0013] The present invention is further configured such that: the pressure sensor is connected to the control module, and the control module generates the weight value based on the electrical signal returned by the pressure sensor.

[0014] The second objective of this invention is to provide an intelligent manhole cover monitoring system.

[0015] The second objective of this invention is achieved through the following technical solution: A smart manhole cover monitoring system, wherein the smart manhole cover further includes: a mobile device for receiving check-in information; The cloud server is used to store, send, and receive one-to-one matching information and weight values; The smart manhole cover is used to detect the weight of objects acting on the stepping layer, generate a weight value, detect the pairing information of surrounding mobile devices, and receive one-to-one pairing information and weight value from the cloud server. When the smart manhole cover detects a weight value, it starts to detect the pairing information of surrounding mobile devices. If there is a pairing information corresponding to the weight value, the stepping layer sends check-in information to the mobile device corresponding to the pairing information.

[0016] In summary, the beneficial technical effects of the present invention are as follows: 1. By detecting the weight value of the stepping layer and the pairing information of surrounding mobile devices, it can determine that the visitor holding the corresponding mobile device is above the stepping layer, thereby avoiding the situation where the visitor can check in with the mobile device simply by passing through without being present, and improving the visitor's sense of participation; 2. After the check-in information is sent, the ring light strip lights up to indicate that the visitor has successfully checked in, which increases the fun of the check-in process; 3. By detecting the tourist's weight and whether the tourist's paired mobile device is nearby, the system can determine whether the user is located at the smart manhole cover. This differs from the conventional method of checking in using mobile device location, and can improve the authenticity and effectiveness of tourist check-ins. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Manhole covers are an important component of urban infrastructure, primarily used to cover underground pipes, cables, and other facilities, ensuring road safety and pedestrian passage. Traditional manhole covers are typically made of cast iron, concrete, or composite materials, providing only basic load-bearing and protective functions, lacking intelligent, interactive, and cultural attributes. With the development of smart cities and the cultural tourism industry, the limitations of traditional manhole covers are becoming increasingly apparent. They are only used for physical coverage and cannot be integrated with urban management or visitor interaction.

[0021] In recent years, some smart manhole covers have upgraded their functionality by integrating sensors and communication modules. Examples include: status monitoring: detecting manhole cover displacement or theft using tilt sensors and GPS positioning (such as municipal manhole covers in some Chinese cities); environmental monitoring: equipped with temperature, humidity, and gas sensors for urban environmental data collection; and anti-theft alarms: triggering alarms based on vibration sensors.

[0022] However, existing technologies still have the following problems: Insufficient interactivity: The functions are concentrated on urban management and do not form effective interactions with pedestrians or tourists. Limited triggering methods: Relying on electronic tags (such as QR codes and NFC), users need to actively operate their mobile phones, resulting in a passive experience. Furthermore, since tourist check-ins are only done by scanning QR codes or using NPCs, it cannot be confirmed whether the mobile device associated with the tourist's account is operated by the person in question. This could lead to situations where someone else checks in on behalf of the tourist or where a QR code can be scanned even if the area is not in the corresponding region, thus raising questions about the authenticity of the check-ins.

[0023] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, in a first aspect, this application provides a smart manhole cover, which includes a stepping layer 1. The stepping layer 1 is used to detect the weight of an object acting on the stepping layer 1, generate a stepping weight value, detect pairing information of surrounding mobile devices, and also to receive one-to-one pairing information and user weight value.

[0025] In this embodiment, the stepping layer 1 can detect the force exerted by an object on its upper surface and convert this force into a stepping weight value through calculations using sensors. This stepping weight value is the weight acting on the stepping layer 1. The stepping layer 1 can also detect pairing information of surrounding mobile devices. This pairing information is a unique identification information distinguishing the corresponding mobile device. In this embodiment, the pairing information includes the mobile device's Bluetooth connection key and device identification information. The device identification information includes the Bluetooth address, name, and device type. The Bluetooth connection key is used for the connection between the stepping layer 1 and the mobile device, while the device identification information is used for the stepping layer 1 to identify the device. The mobile device can be an electronic device such as a mobile phone or tablet. The user weight value refers to the weight of the mobile device user. This user weight value is obtained as follows: When a visitor checks in for the first time, they connect their mobile device to the smart manhole cover via Bluetooth. The visitor stands on the smart manhole cover and their weight is collected by stepping on the cover. The smart manhole cover records the pairing information of the paired mobile device, namely the Bluetooth connection key and device identification information. The initially recorded weight is used as the user weight value and matched with the pairing information to generate a one-to-one pairing information and user weight value. The first time the smart manhole cover is opened, it sends the corresponding pairing information and user weight value to the cloud server, which then sends it to other smart manhole covers.

[0026] When the stepping layer 1 detects that the stepping weight value is close to the user's weight value, the stepping layer 1 starts to detect the pairing information of the surrounding mobile devices. If there is a pairing information corresponding to the user's weight value that is close to the stepping weight value, the stepping layer 1 sends the check-in information to the mobile device corresponding to the pairing information.

[0027] In the embodiments of this application, "the stepping weight value is close to the user's weight value" means that the stepping weight value is within a preset range fluctuating above and below the user's weight value. For example, if the stepping weight value is 50kg and the user's weight value is 49.5kg, the preset range is ±1kg, meaning 50kg is within the range of 49.5kg ± 1kg. In the embodiments of this application, the next action of the stepping layer 1 is triggered only when the stepping weight value is close to the user's weight value: detecting the pairing information of surrounding mobile devices. The technical effect of this sequential triggering of actions is that it reduces device power consumption compared to the stepping layer 1 detecting mobile devices as soon as weight is detected. If there is pairing information corresponding to a user's weight value close to the stepping weight value, it means that the user's weight value and the corresponding pairing information indicate that the tourist is already on the stepping layer 1 where their weight is detected. At this time, the stepping layer 1 sends check-in information to the mobile device corresponding to the pairing information, that is, the stepping layer 1 sends check-in information to the corresponding tourist's mobile device. Before sending, the Bluetooth of the stepping layer 1 and the tourist's mobile device can be paired without further verification. The reason pairing can be done without verification is that the pairing information shared by the cloud service includes the Bluetooth key and device identification information. In other words, the Bluetooth key and Bluetooth identification information are shared, so even if it's not the first step (step 1) that has already been paired with a mobile device, it can still be directly paired with the mobile device.

[0028] Support layer 2, located below step layer 1, is used to support step layer 1.

[0029] Reference Figure 1 The stepping layer 1 is equipped with a prompting component 3, which is used to indicate that the check-in information has been sent to the mobile device.

[0030] In this embodiment, not only can the user's mobile device display a check-in interface on the corresponding application after receiving the check-in information, but the prompt component 3 on the stepping layer 1 will also provide a corresponding prompt, thus giving the user a better interactive experience. The corresponding prompts can be sound, light effects, vibration, etc.

[0031] Reference Figure 1 As an optional implementation, the prompt component 3 is a ring-shaped light strip, which is circumferentially located at the edge of the stepping layer 1.

[0032] In the embodiments of this application, the lighting effect of a ring-shaped light strip is used to indicate to visitors that they have successfully checked in. Specifically, the lighting effect could be that after successful check-in, the ring-shaped light strip changes from a dark state to an illuminated state. To further enhance the interactive experience, the ring-shaped light strip could gradually illuminate from a single point in one direction, or other lighting effects could be used.

[0033] Reference Figure 2 The stepping layer 1 includes a pressure sensor 4, which is located on the bottom surface of the stepping layer 1 and is covered with a flexible cover 5.

[0034] In the embodiments of this application, the pressure sensor 4 is in direct contact with the upper surface of the support layer 2. When the pressure sensor 4 is in contact with the support layer 2, there is a gap between the bottom surface of the stepping layer 1 and the upper surface of the support layer 2, thereby preventing the upper surface of the support layer 2 from contacting the bottom surface of the stepping layer 1 and reducing the weight collected by the pressure sensor 4. When there is weight on the stepping layer 1, the gap between the bottom surface of the stepping layer 1 and the upper surface of the support layer 2 can still be maintained, or the gap can be reduced but not contacted. The flexible cover 5 can prevent the pressure sensor 4 from malfunctioning due to water ingress, thus protecting the pressure sensor 4. The flexible cover 5 is installed on the bottom surface of the stepping layer 1 and covers the pressure sensor 4. Specifically, a protruding ring can be provided on the edge of the flexible cover 5, and an annular groove that mates with the protruding ring can be provided on the bottom surface of the stepping layer 1. The protruding ring and the annular groove are matched to achieve installation. (Not shown in the figure). The connection method of the flexible cover 5 is a conventional means, or other conventional connection methods can be used. The flexible cover 5 is made of rubber. Since there is a certain gap between the support layer 2 and the stepping layer 1, in order to prevent dust and other impurities from entering the gap and interfering with the detection of the stepping weight value, the support layer 2 and the stepping layer 1 need to be dustproofed. The dustproof structure is not shown in the diagram.

[0035] Reference Figure 3 In some embodiments, the upper surface of the support layer 2 is provided with a groove 6 for accommodating the pressure sensor 4.

[0036] In the embodiments of this application, the pressure sensor 4 specifically adopts a strain gauge load cell. The strain gauge load cell detects deformation through metal strain gauges (attached to an elastic body). When a visitor stands on the stepping layer 1, gravity causes slight deformation of the elastic body, and the resistance value of the strain gauge changes accordingly. This change is converted into an electrical signal, which is then used to calculate the weight of the step. There are four strain gauge load cells, located at the four corners of a square to ensure even force distribution. The four strain gauges form a Wheatstone bridge to improve measurement sensitivity. After the pressure sensor 4 is located within the groove 6, since the bottom surface of the groove 6 is lower than the upper surface of the support layer 2, the gap between the bottom surface of the stepping layer 1 and the upper surface of the support layer 2 before stepping is achieved can be reduced. The travel of this gap is the weighing limit of the strain gauge load cell. When the weight on the footrest layer 1 becomes excessive, the strain gauge deforms and the footrest layer 1 descends until its bottom surface contacts the upper surface of the support layer 2. At this point, the strain gauge is no longer subjected to further weight and will not deform further, reaching its load-bearing limit. This limit will not be lower than the theoretical maximum weight of the visitor. The strain gauge will not deform excessively or become damaged due to excessive weight.

[0037] Combination Figure 2 and Figure 3 The bottom surface of the stepping layer 1 is provided with a limiting post 7, and the support layer 2 is provided with a limiting groove 8 that cooperates with the limiting post 7.

[0038] In this embodiment, the limiting post 7 cooperates with the limiting groove 8 to limit the stepping layer 1 and prevent the stepping layer 1 from rotating.

[0039] Reference Figure 4 A controller (not shown in the figure) is installed inside the side step layer. The controller includes a control module, a remote communication module, and a near-end communication module. The control module is connected to the remote communication module and the near-end communication module. The control module is used to obtain the one-to-one matching information and user weight value received by the remote communication module, and when it detects that the stepping weight value is close to the user weight value, it controls the near-end communication module to detect the matching information of the surrounding mobile devices. If there is matching information corresponding to the user weight value that is close to the stepping weight value, it controls the near-end communication module to send the check-in information to the mobile device corresponding to the matching information.

[0040] In the embodiments of this application, the near-end communication module is a Bluetooth module, and the far-end communication module communicates with the cloud server and can be a baseband chip. The baseband chip communicates with the cloud server through a cellular mobile network.

[0041] Reference Figure 4 Pressure sensor 4 is connected to the control module, and the control module generates the pedaling weight value based on the data returned by pressure sensor 4.

[0042] In the embodiments of this application, the pressure sensor 4 is specifically a strain gauge load cell. The strain gauge load cell detects deformation through a metal strain gauge (attached to an elastic body). When a tourist stands on the stepping layer 1, gravity causes slight deformation of the elastic body, and the resistance value of the strain gauge changes accordingly. This change is converted into an electrical signal, which is then used to calculate the weight of the person stepping on the layer.

[0043] The prompt component 3 is also connected to the control module, which controls the display effect of the prompt component 3, i.e., the ring light strip.

[0044] Secondly, embodiments of this application provide an intelligent manhole cover monitoring system, including the aforementioned intelligent manhole cover, and further comprising: Mobile device used to receive attendance information; The cloud server is used to store, send, and receive one-to-one matching information and weight values; The smart manhole cover is used to detect the weight of objects acting on the stepping layer 1, generate weight values, detect the pairing information of surrounding mobile devices, and also to receive one-to-one pairing information and weight values ​​from the cloud server. When the smart manhole cover detects a weight value, it starts to detect the pairing information of surrounding mobile devices. If there is a pairing information corresponding to the weight value, the stepping layer 1 sends check-in information to the mobile device corresponding to the pairing information.
