Description

Technical Field

[0001] The present application relates to the technical field of manhole cover monitoring, and in particular to an intelligent manhole cover monitoring method, device and electronic device based on an operation and maintenance terminal. Background Art

[0002] Currently, the methods for preventing unauthorized wiring in manhole covers mostly adopt enhanced physical protection, that is, using special manhole covers with anti-theft locks (such as rust-proof alloy materials), which require special keys to open and the integrity of the locks needs to be checked regularly; or installing internal barrier devices, that is, setting barbed protection nets or metal gratings between the cables and the manhole covers to increase the difficulty of unauthorized wiring operations. However, the installation complexity and the required installation costs of these methods are relatively high. To solve these problems, the existing method for preventing unauthorized wiring in manhole covers is to set sensors in the manhole covers, and monitor the abnormal movement of the manhole covers through the sensors to achieve real-time detection and alarm of the abnormal movement of the manhole covers.

[0003] However, when operation and maintenance staff such as repair or maintenance workers have to move the manhole cover when checking or repairing the cables in the intelligent manhole cover, the above-mentioned manhole cover monitoring method using sensors is prone to misjudgment of the abnormal position alarm, and the monitoring accuracy of the real abnormal movement (rather than normal maintenance by staff, etc.) of the manhole cover abnormal position alarm function is relatively low, resulting in false alarms of the manhole cover abnormal position alarm, and the false alarm rate of the abnormal movement monitoring of the manhole cover abnormal position alarm function is relatively high.

[0034] Second aspect, the present application provides an intelligent manhole cover monitoring device based on an operation and maintenance terminal, which is controlled by a designated user operation of an operation and maintenance staff member. A speaker with a designated frequency is provided on the operation and maintenance terminal, and at least one designated frequency corresponds to each operation and maintenance staff member. The designated frequency is in the form of high-frequency ultrasonic waves higher than and outside the human ear's hearing range or low-frequency ultrasonic waves lower than and outside the human ear's hearing range.

[0038] Third aspect, the present application further provides an electronic device, including a memory and a processor.

[0039] Fourth aspect, the present application further provides a computer-readable storage medium, which stores computer-executable instructions. When the computer-executable instructions are called and run by a processor, the computer-executable instructions cause the processor to run the method described in the first aspect above.

[0040] The present application brings the following beneficial effects:

[0041] An intelligent manhole cover monitoring method, device and electronic device provided by the present application, the operation and maintenance terminal is controlled by the specified user operation of the operation and maintenance staff, a loudspeaker with a specified frequency is arranged on the operation and maintenance terminal, and at least one specified frequency corresponds to each operation and maintenance staff. The specified frequency is in the form of high-frequency ultrasonic waves higher than and outside the human ear hearing range or low-frequency ultrasonic waves lower than and outside the human ear hearing range. The loudspeaker is used to emit ultrasonic waves of the corresponding specified frequency; an audio receiver for the specified frequency is arranged in the intelligent manhole cover, and each intelligent manhole cover corresponds to a white list of authorized operation and maintenance staff; the method can respond to detecting that the outer cover of the first intelligent manhole cover moves, and judge whether the audio receiver arranged in the first intelligent manhole cover receives the ultrasonic wave of the specified frequency; if it is determined that the audio receiver receives the ultrasonic wave of the first specified frequency, it is determined that the event of the outer cover moving is caused by the operation of the first operation and maintenance staff corresponding to the first specified frequency, and it is judged whether the first operation and maintenance staff is included in the first white list of authorized operation and maintenance staff corresponding to the first intelligent manhole cover; if it is determined that the first operation and maintenance staff is included in the first white list of authorized operation and maintenance staff, the triggering action of the abnormal movement alarm for the first intelligent manhole cover is controlled to be cancelled. In this solution, a loudspeaker with a specified frequency is arranged on the operation and maintenance terminal, and the sound emitted by the loudspeaker exists in the form of high-frequency or low-frequency ultrasonic waves outside the frequency range heard by the human ear (that is, inaudible to the human ear). When the intelligent manhole cover moves and the audio receiver in the intelligent manhole cover detects the ultrasonic wave of the specified frequency at the same time, it is determined that the object of the currently moving intelligent manhole cover is the operation and maintenance staff. If the current operation and maintenance staff meets the authorized personnel in the white list of authorized operation and maintenance staff, the triggering action of the abnormal movement alarm is cancelled. Therefore, for the situation where the operation and maintenance staff has to move the manhole cover when checking, maintaining or repairing the cables in the intelligent manhole cover, this solution can avoid the misjudgment of the abnormal position alarm caused by this situation, improve the monitoring accuracy of the actual abnormal movement (rather than the normal maintenance of the staff, etc.) of the manhole cover abnormal position alarm function, prevent the false alarm of the manhole cover abnormal position alarm caused by this situation, improve the reliability of the manhole cover abnormal position alarm, and reduce the false alarm rate of the abnormal movement monitoring of the manhole cover abnormal position alarm function.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions of the present application with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0049] 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.

[0050] Currently, the false alarm rate of the abnormal monitoring of the manhole cover displacement alarm function is relatively high. Based on this, the embodiments of the present application provide an intelligent manhole cover monitoring method, device, and electronic device based on the operation and maintenance terminal. Through this method, the technical problem of the relatively high false alarm rate of the abnormal monitoring of the manhole cover displacement alarm function can be solved.

[0051] The following further introduces the embodiments of the present invention with reference to the accompanying drawings.

[0052] Figure 1Schematic flowchart of an intelligent manhole cover monitoring method provided by an embodiment of this application. The operation and maintenance terminal is controlled by the designated user operation of the operation and maintenance staff. A speaker with a designated frequency is set on the operation and maintenance terminal. Each operation and maintenance staff corresponds to at least one designated frequency, and the designated frequency is in the form of high-frequency ultrasonic waves higher than and outside the audible range of the human ear or low-frequency ultrasonic waves lower than and outside the audible range of the human ear. The speaker is used to emit ultrasonic waves of the corresponding designated frequency; an audio receiver for the designated frequency is set in the intelligent manhole cover, and each intelligent manhole cover corresponds to a white list of authorized operation and maintenance staff. As Figure 1 shown, the method includes:

[0053] Step S110, in response to detecting that the outer cover of the first intelligent manhole cover moves, determine whether the audio receiver set in the first intelligent manhole cover receives ultrasonic waves of a designated frequency.

[0054] In an embodiment of this application, a speaker with a designated frequency is set on the operation and maintenance terminal. The sound emitted by the speaker exists in the form of high-frequency or low-frequency ultrasonic waves that exceed the audible frequency range of the human ear (that is, inaudible to the human ear) to avoid causing noise interference to the surrounding environment.

[0055] In a possible implementation manner, the above operation and maintenance terminal includes any one or more of the following: intelligent maintenance tool equipment, operation and maintenance detection equipment, and an intelligent chip set in the operation and maintenance staff's work certificate.

[0056] Step S120, if it is determined that the audio receiver receives ultrasonic waves of the first designated frequency, determine that the event of the outer cover moving is caused by the operation of the first operation and maintenance staff corresponding to the first designated frequency, and determine whether the first operation and maintenance staff is included in the first white list of authorized operation and maintenance staff corresponding to the first intelligent manhole cover.

[0057] When the intelligent manhole cover moves and at the same time the audio receiver in the intelligent manhole cover detects ultrasonic waves of a designated frequency, determine that the object moving the current intelligent manhole cover is an operation and maintenance staff, such as an authorized person in the white list of authorized operation and maintenance staff.

[0058] As an optional implementation manner, each intelligent manhole cover corresponds to an image acquisition device, and the image acquisition device is used to acquire image data of the intelligent manhole cover and its surroundings; after the above determination that the event of the outer cover moving is caused by the operation of the first operation and maintenance staff corresponding to the first designated frequency, the method may further include the following steps:

[0059] Obtain the first image data collected by the first image acquisition device corresponding to the first intelligent manhole cover; the first image data includes images of the first operation and maintenance staff performing actions; based on the images of the first operation and maintenance staff performing actions, identify the first operation and maintenance operation content of the first intelligent manhole cover by the first operation and maintenance staff; detect the disconnection and connection conditions of the lines in the intelligent manhole cover, and analyze the second operation and maintenance operation content of the first intelligent manhole cover by the first operation and maintenance staff according to the disconnection and connection conditions of the lines;

[0060] Based on the first operation and maintenance operation content and the second operation and maintenance operation content, conduct comparison and verification, and perform data aggregation processing on the comparison and verification results to obtain the comprehensive operation and maintenance operation content of the first intelligent manhole cover by the first operation and maintenance staff; generate an operation and maintenance process record log of the first intelligent manhole cover by the first operation and maintenance staff according to the comprehensive operation and maintenance operation content, and send the operation and maintenance process record log to the monitoring end corresponding to the first intelligent manhole cover.

[0061] In the embodiments of the present application, the operation and maintenance (maintenance or repair) process of the intelligent manhole cover for the current time can also be recorded. Through this processing method, a more comprehensive and accurate operation and maintenance operation record log of the intelligent manhole cover can be determined, which is convenient for subsequent traceability.

[0062] In an optional implementation manner, each authorized operation and maintenance staff in the white list of authorized operation and maintenance staff corresponds to an authorized operation and maintenance operation content range; the specified frequency is used to represent the identity identifier of the operation and maintenance staff; as Figure 2 shown, the method may further include the following steps:

[0063] Step S210, determine the identity identifier of the first operation and maintenance staff according to the ultrasonic wave of the first specified frequency received by the audio receiver;

[0064] Step S220, determine the first authorized operation and maintenance operation content range corresponding to the first operation and maintenance staff in the white list of authorized operation and maintenance staff;

[0065] Step S230, judge whether the actual operation content of the first operation and maintenance staff exceeds the first authorized operation and maintenance operation content range according to the first operation and maintenance operation content and the second operation and maintenance operation content;

[0066] Step S240, if the actual operation content of the first operation and maintenance staff exceeds the first authorized operation and maintenance operation content range, control to activate the abnormal alarm trigger action for the first intelligent manhole cover.

[0067] Among them, the authorized operation and maintenance operation content range includes any one or more of the following: opening the intelligent manhole cover to view the cables, disconnecting the circuit in the intelligent manhole cover, connecting the circuit in the intelligent manhole cover, deleting the circuit in the intelligent manhole cover, and adding the circuit in the intelligent manhole cover.

[0068] Exemplarily, different specified frequencies correspond to different authorization permissions of authorized personnel. For example, the first specified frequency (such as 400 Hz) corresponds to the first authorization permission of the authorized personnel, which is only able to open the intelligent manhole cover for viewing and has no permission to modify the induction trigger circuit on the intelligent manhole cover; the second specified frequency (such as 600 Hz) corresponds to the second authorization permission of the authorized personnel, which is not only able to open the intelligent manhole cover for viewing, but also has the permission to modify and repair the induction trigger circuit on the intelligent manhole cover.

[0069] In the embodiments of the present application, different staff members correspond to different intelligent manhole cover control permissions. Through the above processing method, different staff members can be finely distinguished corresponding to different intelligent manhole cover control permissions, avoiding the operation of certain permissions by staff members without such permissions.

[0070] In step S130, if it is determined that the first operation and maintenance staff member is included in the white list of the first authorized operation and maintenance staff members, then control is performed to cancel the triggering action of the abnormal movement alarm for the first intelligent manhole cover.

[0071] In a possible implementation manner, when the audio receiver in the intelligent manhole cover detects ultrasonic waves of a specified frequency, it is determined that the object moving the intelligent manhole cover currently is an authorized person in the white list, thereby canceling the triggering action of the abnormal movement alarm.

[0072] As an example, the number of different numerical frequencies included in the ultrasonic waves is multiple, and the switching sequence logic between different numerical frequencies is used to represent the operation and maintenance operation content request password of the operation and maintenance staff sent by the operation and maintenance end for the first intelligent manhole cover; the white list of the first authorized operation and maintenance staff members includes multiple specified frequency switching sequence logics, and each specified frequency switching sequence logic is used to represent the correct password corresponding to a range of authorized operation and maintenance operation contents; all the specified frequency switching sequence logics in the white list of the first authorized operation and maintenance staff members are stored in the audio receiver; the specific steps for determining the first authorized operation and maintenance operation content range corresponding to the first operation and maintenance staff member in the white list of the authorized operation and maintenance staff members may include the following:

[0073] Judge whether the actual frequency switching sequence logic in the ultrasonic waves received by the audio receiver set in the first intelligent manhole cover conforms to any one or more of all the specified frequency switching sequence logics; if the actual frequency switching sequence logic conforms to the first specified frequency switching sequence logic in all the specified frequency switching sequence logics in the white list of the first authorized operation and maintenance staff members, it is determined that the operation and maintenance request password sent by the operation and maintenance end belongs to the first correct password corresponding to the first specified frequency switching sequence logic, and it is determined that the range of authorized operation and maintenance operation contents corresponding to the first operation and maintenance staff member is the first authorized operation and maintenance operation content range corresponding to the first correct password.

[0074] Exemplarily, the sound waves emitted by the operation and maintenance terminal can also be switched between multiple different frequencies to implement passwords formed by various different frequency ultrasonic wave forms. An instruction frequency switching sequence logic is set in the audio receiver in the intelligent manhole cover. When the actual sequence of the ultrasonic wave frequency switching emitted by the operation and maintenance terminal conforms to the instruction frequency switching sequence logic set in the audio receiver, it is determined that the password is correct, and then it can be determined that the current operator of the intelligent manhole cover conforms to the permissions corresponding to the password. For example, 100 Hz represents the number 1, 200 Hz represents the number 2, 300 Hz represents the number 3... and so on. When the acoustic wave password (switched from 200 Hz to 600 Hz and then to 500 Hz) emitted by the operation and maintenance terminal conforms to the specified password (265), it is determined that the current operator of the intelligent manhole cover conforms to the specified permissions corresponding to the 265 password. For example, some permissions allow both opening the intelligent manhole cover for viewing and modifying and maintaining the induction trigger circuit on the intelligent manhole cover.

[0075] Through the above-mentioned processing method, different staff can be more precisely distinguished corresponding to different intelligent manhole cover control permission ranges through different passwords, avoiding operations of certain permissions by staff without such permissions.

[0076] In the embodiments of the present application, a specified frequency speaker is set on the operation and maintenance terminal. The sound emitted by the speaker exists in the form of high-frequency or low-frequency ultrasonic waves that exceed the frequency range audible to the human ear (that is, inaudible to the human ear). When the intelligent manhole cover moves and at the same time the audio receiver in the intelligent manhole cover detects the ultrasonic waves of the specified frequency, it is determined that the object moving the intelligent manhole cover is the operation and maintenance staff. If the current operation and maintenance staff conforms to the authorized personnel in the white list of authorized operation and maintenance staff, the triggering action of the abnormal movement alarm is cancelled. Therefore, for the situation where the operation and maintenance staff have to move the manhole cover when inspecting, maintaining or repairing the cables in the intelligent manhole cover, this solution can avoid misjudgment of the abnormal position alarm caused by this situation, improve the monitoring accuracy of the real abnormal movement (rather than normal maintenance by staff, etc.) of the intelligent manhole cover abnormal position alarm function, prevent false alarms of the manhole cover abnormal position alarm caused by this situation, improve the reliability of the manhole cover abnormal position alarm, and reduce the false alarm rate of the abnormal movement monitoring of the manhole cover abnormal position alarm function.

[0077] In some embodiments, a permanent magnet structure is provided on the outer side of the inner cover of the first intelligent manhole cover, and a magnetic induction coil is provided on the inner side of the outer cover of the first intelligent manhole cover; the magnetic induction coil is connected to the induction circuit, and the circuit in the induction circuit is in an open state. A power module and a communication module are also provided in the induction circuit; before the above step S110, the method may further include the following steps:

[0078] In response to electromagnetic induction generated between the permanent magnet structure and the magnetic induction coil, the circuit in the induction circuit is triggered to close through 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 first intelligent manhole cover has moved;

[0079] If it is determined that the first operation and maintenance staff is included in the white list of the first authorized operation and maintenance staff, the triggering action of the abnormal movement alarm for the first intelligent manhole cover is controlled to be cancelled, which may specifically include the following steps: the communication module that has formed a loop with the power supply module sends the abnormal movement information to the monitoring end corresponding to the first intelligent manhole cover, so that the monitoring end executes the abnormal position alarm for the intelligent manhole cover based on the abnormal movement information; among them, the abnormal movement information includes the event that the outer cover of the intelligent manhole cover has moved; if it is determined that the first operation and maintenance staff is included in the white list of the first authorized operation and maintenance staff, the abnormal movement information sent by the communication module to the monitoring end is intercepted to cancel the triggering action of the abnormal movement alarm for the first intelligent manhole cover.

[0080] In the embodiment of the present application, the positions of the permanent magnet structure and the magnetic induction coil can also be replaced with each other, that is, a magnetic induction coil is arranged on the outer side of the inner cover of the intelligent manhole cover, and a permanent magnet structure is arranged on the inner side of the outer cover of the intelligent manhole cover, so as to realize more induction forms. When the intelligent manhole cover does not move, the 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 induction circuit, 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 induction circuit, the circuit in the induction circuit is triggered to close by using the electromagnetic induction of this morphological change, so that the power supply module can supply power to the communication module. Through this triggering method of power supply for the communication module in the induction circuit, the realization process of the self-excited circuit is achieved. Through the above electromagnetic induction triggering method, the continuous operation of the power supply of the sensor can be avoided, and the required power for triggering is extremely small, which can extend the effective working time of the sensor power supply and avoid affecting the settings inside the manhole cover and a large amount of labor costs caused by replacing the battery multiple times.
