[0002] Currently, the existing method for preventing unauthorized wiring in manhole covers is to install sensors inside the manhole covers to detect any abnormal movement of the manhole covers, so as to achieve real-time detection and alarm of abnormal movement of the manhole covers. However, sensors consume a relatively large amount of power during operation, resulting in a relatively short battery life for the sensors, that is, a short service life, which forces workers to often open the manhole covers to replace the batteries of the sensors installed inside the manhole covers. Therefore, due to the short battery life of traditional sensors, the cost of large-scale replacement of sensor batteries is relatively high. Summary of the Invention

[0015] The present application brings the following beneficial effects: An intelligent manhole cover monitoring method, device and electronic device based on an induction loop are provided in this application. A permanent magnet structure is arranged at a first position of the intelligent manhole cover, and a magnetic induction coil is arranged at a second position of the intelligent manhole cover. The first position is the outer side of the inner cover of the intelligent manhole cover and the second position is the inner side of the outer cover of the intelligent manhole cover, or the first position is the inner side of the outer cover of the intelligent manhole cover and the second position is the outer side of the inner cover of the intelligent manhole cover. The magnetic induction coil is connected to an electromagnetic induction loop, and the circuit in the electromagnetic induction loop is in an open state. A power supply module and a communication module are also arranged in the electromagnetic induction loop. This method can respond to the electromagnetic induction generated between the permanent magnet structure and the magnetic induction coil, trigger the closing of the circuit in the electromagnetic induction loop through the electromagnetic induction, so that the power supply module and the communication module form a loop. In response to the power supply module and the communication module forming a loop, it is determined that a displacement occurs between the permanent magnet structure and the magnetic induction coil, and based on the displacement that occurs between the permanent magnet structure and the magnetic induction coil, it is determined that the outer cover of the intelligent manhole cover has moved. A movement monitoring message is sent through the communication module that has formed a loop with the power supply module, so that the monitoring terminal performs an out-of-position alarm action for the intelligent manhole cover based on the movement monitoring message. Among them, the movement monitoring message contains the event that the outer cover of the intelligent manhole cover has moved. In this solution, the electromagnetic induction circuit is in an open state when the intelligent manhole cover does not move. When the outer cover of the intelligent manhole cover moves, a displacement occurs between the permanent magnet and the magnetic induction coil, and then electromagnetic induction is generated. The electromagnetic induction closes the circuit in the electromagnetic induction loop, and the power supply module and the remote communication module form a loop. That is, through the morphological change between the permanent magnet structure and the magnetic induction coil in the electromagnetic induction loop, the morphological change of the electromagnetic induction is used to trigger the closing of the circuit in the electromagnetic induction loop, so that the power supply module can supply power to the communication module. Through this way of triggering the power supply of the communication module in the electromagnetic induction loop, the realization process of the self-excited circuit is achieved. Through the above electromagnetic induction triggering method, it is possible to avoid the continuous operation of the power supply of the sensor, and the required power for triggering is extremely small, which can extend the effective working time of the sensor power supply, avoid the influence on the manhole cover setting caused by replacing the battery multiple times and a large amount of labor costs, and solve the technical problem of the high cost of replacing the battery corresponding to the sensor.

[0016] To make the above objects, features, and advantages of this application more obvious and understandable, the following specifically gives preferred embodiments and, in conjunction with the accompanying drawings, makes a detailed description as follows. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to more clearly illustrate the specific embodiments of this application or the technical solutions in the prior art, the following will briefly introduce the drawings required for use in the description of the specific embodiments or the prior art. Obviously, the drawings below are some embodiments of this application. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

Detailed implementation manners

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0020] The terms "including" and "having" and any variations thereof mentioned in the embodiments of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes other steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0021] Currently, the methods for monitoring the movement of manhole covers include: increasing the intensity of manual inspections, which requires a large amount of labor costs and round-the-clock inspections; using sensor solutions such as vibration / light / tilt, etc. The power supply of the sensors works continuously, and it is difficult for the service life to reach the expected value. The cost of large-scale replacement and frequent replacement is too high. Therefore, the working life of the power supply set in the induction loop is short, resulting in multiple battery replacements affecting the settings inside the manhole cover. Moreover, when the outer cover moves, the sensitivity of the abnormal movement monitoring of the manhole cover abnormal alarm function is low, that is, the sensitivity of abnormal movement detection for manhole cover monitoring through sensors is low.

[0022] Based on this, the embodiments of the present application provide an intelligent manhole cover monitoring method, device and electronic device based on an induction loop, and through this method, technical problems such as the high cost of replacing the battery corresponding to the sensor can be solved.

[0023] The embodiments of the present invention will be further introduced below with reference to the accompanying drawings.

[0024] Figure 1Schematic diagram of a method for monitoring intelligent manhole covers based on an induction loop provided by an embodiment of the present application. Among them, a permanent magnet structure is provided at a first position of the intelligent manhole cover, and a magnetic induction coil is provided at a second position of the intelligent manhole cover; the first position is the outer side of the inner cover of the intelligent manhole cover and the second position is the inner side of the outer cover of the intelligent manhole cover, or the first position is the inner side of the outer cover of the intelligent manhole cover and the second position is the outer side of the inner cover of the intelligent manhole cover (when the first position is the outer side of the inner cover of the intelligent manhole cover and the second position is the inner side of the outer cover of the intelligent manhole cover, the electromagnetic induction loop is provided on the outer cover of the intelligent manhole cover); the magnetic induction coil is connected to the electromagnetic induction loop, the circuit in the electromagnetic induction loop is in an open state, and a power supply module and a communication module are also provided in the electromagnetic induction loop. As Figure 1 shown, the method includes: Step S110, in response to electromagnetic induction generated between the permanent magnet structure and the magnetic induction coil, triggering the circuit in the electromagnetic induction loop to close through electromagnetic induction, so that the power supply module and the communication module form a loop.

[0025] For the hardware structure of the induction part in the intelligent manhole cover, for example, as Figure 2 shown, a permanent magnet structure is provided on the outer side of the inner cover, and a magnetic induction coil is provided on the inner side of the outer cover. The magnetic induction coil is connected to the electromagnetic induction loop provided on the outer cover, and a power supply module and a communication module with a long-term (such as 10 years) working life are provided in the induction loop, such as a power supply and a communication module with a shelf life of ten years are provided in the induction loop. When the outer cover of the intelligent manhole cover moves, a displacement is generated between the permanent magnet and the magnetic induction coil, and then electromagnetic induction is generated. The electromagnetic induction causes the circuit in the electromagnetic induction loop to close, and the power supply module and the remote communication module form a loop. Through the above trigger circuit method of the induction circuit, the realization process of the self-excited circuit is achieved.

[0026] As an optional implementation manner, the above electromagnetic induction loop can be automatically reset after completing the above trigger process. For example, a triode switch device is correspondingly provided at the open position in the electromagnetic induction loop, and the triode switch device is in an open state when the electromagnetic induction loop is in an open state; the above response to electromagnetic induction generated between the permanent magnet structure and the magnetic induction coil, triggering the circuit in the electromagnetic induction loop to close through electromagnetic induction, may specifically include the following steps: In response to electromagnetic induction generated between the permanent magnet structure and the magnetic induction coil, triggering the triode in the triode switch device to conduct through the self-excited current generated by the electromagnetic induction, so that the triode switch device is switched from the open state to the closed state; the current value of the self-excited current is less than the specified current value; In response to the disappearance of the self-excited current in the electromagnetic induction loop, the triode in the triode switch device automatically resets to the off state, so that the triode switch device is automatically switched from the closed state to the open state.

[0027] Through the automatic reset process of the above triode switch device after completing the above triggering process, the process of controlling its reset through external protocol instructions can be saved, and further the monitoring cost of the intelligent manhole cover can be saved.

[0028] Step S120: In response to the power supply module and the communication module forming a loop, determine that a displacement occurs between the permanent magnet structure and the magnetic induction coil, and determine that the outer cover of the intelligent manhole cover moves based on the displacement that occurs between the permanent magnet structure and the magnetic induction coil.

[0029] In practical applications, only when the outer cover of the intelligent manhole cover moves, a displacement will occur between the permanent magnet and the magnetic induction coil, and then electromagnetic induction will be generated. The electromagnetic induction closes the circuit in the electromagnetic induction loop, so that the power supply and the remote communication module form a loop.

[0030] Step S130: Send a movement monitoring message through the communication module that has formed a loop with the power supply module, so that the monitoring terminal performs an out-of-position alarm action for the intelligent manhole cover based on the movement monitoring message.

[0031] Among them, the movement monitoring message includes the event that the outer cover of the intelligent manhole cover moves. When the power supply module and the remote communication module form a loop, the power supply module can provide power for the remote communication module, so that the remote communication module can send out communication information, thereby realizing the manhole cover out-of-position alarm function and improving the sensitivity of the movement monitoring of the manhole cover out-of-position alarm function.

[0032] In a possible implementation manner, data reporting can be implemented through the communication module, such as remotely transmitting the reported data after summarizing and processing through the intelligent lamp post. As an example, a smart lamp post device is correspondingly set for several intelligent manhole covers, and the distance between the installation position of the smart lamp post device and the corresponding several intelligent manhole covers is less than a specified distance; a positioning device and an image acquisition device are arranged on the smart lamp post device, and the image acquisition direction of the image acquisition device faces the intelligent manhole cover; this step S130 may specifically include the following steps: Send the movement monitoring message to the smart lamp post device through the communication module that has formed a loop with the power supply module; collect and summarize the position information of several intelligent manhole covers and the movement monitoring messages correspondingly sent by several intelligent manhole covers through the smart lamp post device to obtain summary manhole cover monitoring information corresponding to several intelligent manhole covers, and report the summary manhole cover monitoring information to the monitoring terminal by means of wireless communication; The monitoring terminal screens out false alarm information from the summary manhole cover monitoring information according to the surrounding images of the intelligent manhole cover collected by the image acquisition device to obtain the final manhole cover monitoring information after false alarm information screening, and determines whether to perform an out-of-position alarm action for the intelligent manhole cover based on the final manhole cover monitoring information.

[0033] The remote data (i.e., the aggregated monitoring information of the manhole cover) is reported through the communication module and the intelligent lamp post device, and then the false alarm information in the remote data is screened by the monitoring terminal, achieving a more accurate anti-false alarm effect for the induction circuit.

[0034] In the embodiment of the present application, when the intelligent manhole cover does not move, the electromagnetic induction circuit is in an open state. When the outer cover of the intelligent manhole cover moves, a displacement occurs between the permanent magnet and the magnetic induction coil, and then electromagnetic induction is generated. The electromagnetic induction closes the circuit in the electromagnetic induction loop, and the power supply module and the remote communication module form a loop. That is, through the morphological change between the permanent magnet structure and the magnetic induction coil in the electromagnetic induction loop, the morphological change of electromagnetic induction is used to trigger the closing of the circuit in the electromagnetic induction loop, enabling the power supply module to supply power to the communication module. Through this power supply triggering method of the communication module in the electromagnetic induction loop, the realization process of the self-excited circuit is achieved, improving the sensitivity and accuracy of the displacement monitoring of the manhole cover. Moreover, through the above electromagnetic induction triggering method, the continuous operation of the sensor power supply can be avoided, and the required power for triggering is extremely small, which can extend the effective working time of the sensor power supply, avoid affecting the internal settings of the manhole cover and incurring a large amount of labor costs due to multiple battery replacements, and also avoid affecting the internal settings of the manhole cover due to frequent battery replacements.

[0035] In some embodiments, an RL-type multiple filtering circuit is provided in the electromagnetic induction loop. The method may further include the following steps: The RL-type multiple filtering circuit excludes the situation where the outer cover vibrates due to a vehicle passing by during the movement of the outer cover by filtering the short voltage, and obtains the final movement monitoring information after excluding the vibration situation; The final movement monitoring information is sent through the communication module, so that the monitoring terminal determines whether to execute an out-of-position alarm action for the intelligent manhole cover based on the final movement monitoring information.

[0036] It should be noted that the RL-type multiple filtering circuit can be a resistor-inductor circuit (Resistor-inductor circuit, RL circuit), that is, an RL filter or an RL network, which is an infinite impulse response electronic filter composed of a resistor and an inductor element in series or parallel and driven by a voltage source. Passive linear elements such as resistors (R), capacitors (C), and inductor elements (L) can be used to form 4 different circuits: RC circuits, RL circuits, LC circuits, and RLC circuits, all of which can be used as passive filters. By using the RL-type multiple filtering circuit to filter the short voltage to exclude the situation where the outer cover vibrates due to a vehicle passing by during the movement of the outer cover, the anti-false alarm effect of the induction circuit can be further achieved.

[0037] In some embodiments, there can be various variation forms in the misalignment process and assembly process of the manhole cover. The relative movement method can take into account various movement trajectories, distances, directions, and times, etc. In terms of hardware, there are contactable and non-contactable ones. The contactable ones are divided into assemblable and non-assemblable ones. The setting of the permanent magnet and the setting of the coil can be in the form of induction lines, induction surfaces, and induction regions. As an example, there are various relative assembly positions between the permanent magnet structure and the magnetic induction coil, and each relative assembly position corresponds to a relative movement method with a movement variation form. Among them, the relative movement method includes a relative movement trajectory, a relative movement distance, a relative movement direction, and a relative movement time.

[0038] Based on this, the step of determining the displacement between the permanent magnet structure and the magnetic induction coil in response to the electromagnetic induction generated between them in the above step S110 can specifically include the following steps: In response to the electromagnetic induction generated between the permanent magnet structure and the magnetic induction coil, according to the induction information of the electromagnetic induction, determine the actual relative movement trajectory, actual relative movement distance, actual relative movement frequency, actual relative movement direction, and actual relative movement time between the permanent magnet structure and the magnetic induction coil; where the induction information includes induction line information, induction surface information, induction region form, induction effect magnitude, and induction effect time; If the actual relative movement trajectory conforms to the specified operation and maintenance movement trajectory, the actual relative movement distance conforms to the specified operation and maintenance movement distance, the actual relative movement direction conforms to the specified operation and maintenance movement direction, the actual relative movement frequency conforms to the specified operation and maintenance movement frequency, and the actual relative movement time conforms to the specified operation and maintenance movement time, then determine that the displacement occurring between the permanent magnet structure and the magnetic induction coil belongs to the displacement of the normal operation and maintenance type; If the actual relative movement trajectory conforms to the specified normal vibration trajectory, the actual relative movement distance conforms to the specified normal vibration distance, the actual relative movement direction conforms to the specified normal vibration direction, the actual relative movement frequency conforms to the specified normal vibration frequency, and the actual relative movement time conforms to the specified normal vibration time, then determine that the displacement occurring between the permanent magnet structure and the magnetic induction coil belongs to the displacement of the normal vibration type; If the actual relative movement trajectory does not conform to the specified operation and maintenance movement trajectory and the specified normal vibration trajectory, the actual relative movement distance does not conform to the specified operation and maintenance movement distance and the specified normal vibration distance, the actual relative movement frequency conforms to the specified operation and maintenance movement frequency and the specified normal vibration frequency, or the actual relative movement direction does not conform to the specified operation and maintenance movement direction and the specified normal vibration direction, or the actual relative movement time does not conform to the specified operation and maintenance movement time and the specified normal vibration time, then determine that the displacement occurring between the permanent magnet structure and the magnetic induction coil belongs to the displacement of the abnormal movement type other than the displacement of the normal operation and maintenance type and the displacement of the normal vibration type.

[0039] Through the above processing method, it is possible to accurately distinguish among three situations: the abnormal movement of the manhole cover, the normal vibration of the manhole cover caused by the passing of regular vehicles, and the normal movement of the manhole cover caused by the regular operation and maintenance process of the staff, making the monitoring of the manhole cover more accurate and comprehensive.

[0040] In some embodiments, the above step S130 may specifically include the following steps: in response to the power module and the communication module forming a loop, trigger the power module to supply power to the communication module; If the displacement between the permanent magnet structure and the magnetic induction coil belongs to the displacement of the abnormal movement type, send out the abnormal movement monitoring information through the communication module that has been supplied with power by the power module, so that the monitoring terminal performs the abnormal position alarm action for the intelligent manhole cover based on the abnormal movement monitoring information; If the displacement between the permanent magnet structure and the magnetic induction coil belongs to the displacement of the regular operation and maintenance type, send out the operation and maintenance monitoring information through the communication module that has been supplied with power by the power module, so that the monitoring terminal performs the operation and maintenance monitoring action for the intelligent manhole cover based on the operation and maintenance monitoring information; If the displacement between the permanent magnet structure and the magnetic induction coil belongs to the displacement of the regular vibration type, determine the event that the outer cover of the intelligent manhole cover moves as the event that the intelligent manhole cover vibrates caused by the passing of a vehicle, and control the communication module to stop sending the movement monitoring information to prevent false alarms of the induction circuit.

[0041] Through the above processing method, it is possible to perform action feedback of different processing methods corresponding to the three situations of the abnormal movement of the manhole cover, the normal vibration of the manhole cover caused by the passing of regular vehicles, and the normal movement of the manhole cover caused by the regular operation and maintenance process of the staff, making the monitoring of the manhole cover more comprehensive and efficient.
