[0037] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the embodiments of the present invention, and not all structures.

[0038] Example 1

[0039] Figure 1 This is a block diagram of the module structure of the cable anti-theft alarm device provided in Embodiment 1 of the present invention, as shown below. Figure 1 As shown, the device specifically includes:

[0040] The target object recognition module 101 is configured to acquire image information of the anti-theft area through a camera, identify the target object in the image information, and obtain the displacement data to be registered.

[0041] The data comparison module 102 is configured to acquire the tension parameter data of the cable through a tension sensor and compare the movement data to be registered with the tension parameter data.

[0042] The matching alarm module 103 is configured to trigger a burglar alarm when the comparison result meets the matching alarm conditions.

[0043] In this embodiment, the application scenario is to automatically monitor for cable theft and promptly issue an alarm. Specifically, the system identifies the target object in the image information of the anti-theft area and obtains the displacement data to be registered. It also acquires the cable's tension parameters using a tension sensor, compares the above data, and if the comparison result meets the matching alarm conditions, triggers an anti-theft alarm.

[0044] Based on the above usage scenarios, it can be understood that the executing entity of this application embodiment can be an intelligent electronic device integrated with a cable anti-theft alarm device, such as a laptop, tablet computer or mobile phone, etc., and no specific limitation is made here.

[0045] In this embodiment, the anti-theft zone can be understood as the area requiring monitoring of cable equipment. It can be understood that the anti-theft zone can be a high-altitude area on the ground or a tunnel area where cable equipment is installed. The image information can be images of the anti-theft zone acquired by a camera at preset time intervals, or images extracted from video information of the anti-theft zone. The target object can be understood as a monitored object suspected of theft. The displacement data to be registered can be understood as data characterizing the movement trajectory of the target object.

[0046] In this embodiment, acquiring the image information of the anti-theft area via a camera can be achieved by the camera capturing images of the anti-theft area at preset time intervals. The time interval is preset by technicians according to actual needs. Alternatively, the anti-theft area can be captured as video information by a camera, and images can be extracted from it to obtain the image information of the anti-theft area. Identifying the target object in the image information to obtain the displacement data to be registered can be done by identifying the target object in multiple images based on the temporal sequence of the images to determine its movement trajectory.

[0047] In this embodiment, a camera positioned in the anti-theft area acquires image information of the anti-theft area based on a preset time interval or by capturing data from video information. It is understood that the camera is oriented towards the cable laying direction. The target object recognition module 101 identifies the image information based on the temporal sequence of the images to determine the target object and its movement trajectory.

[0048] In this embodiment, the tensile force can be understood as the deformation of an object under the action of an external force within its elastic limit, which is proportional to the external force. The deformation varies depending on the direction of the force, and the force that causes the object to extend. The tensile force parameter data can be understood as the tensile force value of the cable support on the cable when the cable is mounted on the cable bracket. The tensile force parameter data can be obtained by a tensile sensor installed on the cable.

[0049] In this embodiment, the method for acquiring the cable's tensile parameter data using a tension sensor can be that the elastic element of the tension sensor undergoes elastic deformation under external force, causing the resistance strain gauge attached to its surface to deform accordingly. The resistance value of the strain gauge changes with the deformation, and this resistance change is then converted into a measurable electrical signal by a measuring circuit, thereby acquiring the cable's tensile parameter data. The comparison between the movement data to be registered and the tensile parameter data can be understood as comparing the movement trajectory of the target object with the cable's tensile parameter value.

[0050] In this embodiment, a tension sensor disposed on the surface of the cable acquires the cable's tension parameter data in real time. Specifically, the elastic element of the tension sensor undergoes elastic deformation under external force, causing the resistance strain gauge attached to its surface to deform accordingly. The resistance value of the strain gauge changes with the deformation, and this resistance change is converted into a measurable electrical signal by a measuring circuit, thereby acquiring the cable's tension parameter data. Optionally, the tension sensor can also acquire the tension parameter data based on a preset time interval. The data comparison module 102 acquires the tension parameter data and the registration movement data, and compares them.

[0051] In this embodiment, the comparison result can be understood as the matching result of the tensile parameter data and the movement data to be registered. The matching alarm condition can be understood as a standard used to judge theft behavior. Meeting the matching alarm condition is understood as meeting the theft behavior standard. The anti-theft alarm can be understood as an alarm prompt for theft behavior. Specifically, the anti-theft alarm can be triggered by sending a data pop-up window or SMS containing theft behavior information to the client to promptly notify staff. Optionally, alarm prompts can also be broadcast in the anti-theft area and lights can be flashed to deter cable thieves.

[0052] In this embodiment, the matching alarm module 103 matches the comparison results of the tension parameter data and the movement data to be registered with the standards used to determine theft. If the comparison results meet the standards for theft, theft is confirmed. The matching alarm module 103 sends a data pop-up or SMS containing theft information to the client to promptly notify staff. Simultaneously, an alarm sound is broadcast and lights flash in the anti-theft area to deter cable thieves.

[0053] The technical solution provided in this embodiment includes a target object recognition module configured to acquire image information of the anti-theft area via a camera, identify target objects in the image information, and obtain displacement data to be registered; a data comparison module configured to acquire cable tension parameter data via a tension sensor, and compare the displacement data to be registered with the tension parameter data; and a matching alarm module configured to trigger an anti-theft alarm when the comparison result meets the matching alarm conditions. This solution solves the problems of poor monitoring accuracy and low efficiency in the existing technology for cable anti-theft, effectively improving cable monitoring efficiency, reducing false alarms, and achieving the technical effect of automatically monitoring cables and providing timely warnings, thereby improving the security of cable storage.

[0054] Example 2

[0055] Figure 2 This is a block diagram of the module structure of the cable anti-theft alarm device provided in Embodiment 1 of the present invention, as shown below. Figure 2 As shown, the device specifically includes:

[0056] The target object recognition module 201 is configured to recognize the target object based on a preset identifiable object in the image information, and to obtain the displacement data to be registered based on the displacement data of the target object in each different image in the image information.

[0057] In this embodiment, the preset identifiable object can be understood as an object that can exhibit cable behavior, pre-set by technicians. In this embodiment, a person is used as an example of the preset identifiable object. The displacement data can be understood as the positional information data of the target object in different images. Specifically, the displacement data can be the latitude and longitude data of the target object or the coordinate data of the target object in the coordinate system of the anti-theft area.

[0058] In this embodiment, identifying the target object based on a preset identifiable object in the image can be achieved by inputting image information into a pre-trained recognition model to determine the person in the image information. Obtaining the registration displacement data based on the displacement data of the target object in different images can be achieved by acquiring the position information of the person in multiple images in temporal order and determining the person's displacement trajectory based on changes in the position information.

[0059] In this embodiment, the target object recognition module 201 identifies people in the images of the anti-theft area using a pre-trained recognition model, obtains the position information of people in multiple images based on the time sequence of the images, and determines the displacement trajectory of people based on the changes in the position information.

[0060] In this embodiment, optionally, the data comparison module 202 is specifically configured as follows:

[0061] The trigger times and data parameter values ​​of the tension parameter data and the movement data to be registered are compared respectively.

[0062] In this embodiment, the data comparison module 202 compares the trigger times of the tension parameter data and the movement data to be registered. Specifically, the trigger time can be the time point corresponding to the change in the tension value. The trigger time of the movement data to be registered can be the image capture time point corresponding to the change in the displacement of the target object. The data comparison module 202 compares the trigger time of the tension parameter data and the trigger time of the movement data to be registered.

[0063] In this embodiment, optionally, the trigger time for the tension parameter data can be the time point corresponding to the tension value when the change in the tension parameter data value is greater than a preset change value. The trigger time for the movement data to be registered can be the time point at which the image corresponding to the position data of the target object is captured when the distance between the target object and the cable equipment is less than a preset distance. Specifically, comparison based on trigger time can be understood as comparing the tension parameter data and the movement data to be registered in association. The data parameter value can be understood as the value of the tension parameter data and the position coordinates representing the spatial position of the target object. Specifically, comparison based on data parameter value can be understood as comparing the tension parameter data and the movement data to be registered separately.

[0064] In this embodiment, the data comparison module 202 compares the trigger times of the tension parameter data and the movement data to be registered. Specifically, when the change in the cable tension value from the original tension value is greater than a preset change value, the time point corresponding to the current tension value is obtained and determined as the trigger time of the tension parameter data. The preset change value is derived by technicians based on multiple simulations of cable theft. Simultaneously, when the distance between the person and the cable is less than a preset distance, the time point of the image capture corresponding to the person's current spatial position is obtained and determined as the trigger time of the movement data to be registered. The trigger times of the tension parameter data and the movement data to be registered are then compared.

[0065] It is understandable that if the change in cable tension value from the original value is too small, it may be due to changes in cable tension value caused by external environmental factors. For example, wind or snowfall may cause cable swaying or changes in cable load, thus altering the cable tension value. Similarly, if a person appears in the image of the anti-theft area but is too far away from the cable equipment, it may simply be a passerby walking through the cable anti-theft area. By setting a preset change value, changes in cable pressure value caused by external environmental factors can be eliminated. By setting a preset distance, situations where passersby walking through the anti-theft area are mistakenly identified as thieves can be avoided. Through these settings, false accusations of theft can be prevented.

[0066] In this embodiment, the data comparison module 202 compares the data parameter values ​​of the tension parameter data and the movement data to be registered. Specifically, the data comparison module 202 compares the tension parameter data and the movement data to be registered respectively. This includes setting a preset tension threshold and comparing the current tension value with the preset tension threshold. The tension threshold is the minimum tension boundary value that satisfies the cable theft situation. Furthermore, a preset displacement relationship is obtained in advance through model learning and training. For example, multiple different cable theft scenarios are simulated to generate the displacement relationship of the target object, and the data comparison module 202 compares the current target object's displacement relationship with the preset displacement relationship. Specifically, this can be a comparison of displacement curves or discrete position points.

[0067] In this embodiment, optionally, the matching alarm module 203 is specifically configured as follows:

[0068] The triggering time of the tension parameter data and the registration movement data is consistent, and the data parameter value of the tension parameter data is determined to be greater than the preset tension threshold, and the data parameter value of the registration movement data satisfies the preset displacement relationship.

[0069] In this embodiment, if the matching alarm module 203 determines through comparison that the trigger time of the tension parameter data is consistent with the trigger time of the movement data to be registered, and the data parameter value of the tension parameter data is determined to be greater than a preset tension threshold, and the data parameter value of the movement data to be registered satisfies a preset displacement relationship, then the comparison result is determined to meet the matching alarm conditions, and an anti-theft alarm is triggered.

[0070] For example, the matching alarm module 203 determines, through comparison, that the trigger time of the tension parameter data and the trigger time of the movement data to be registered are both 17:00, and that the current tension value is 20 Newtons, which is greater than the preset tension threshold of 15 Newtons, and that the movement trajectory drawn based on the data parameter values ​​of the movement data to be registered is consistent with the movement trajectory of the preset displacement relationship. If the comparison result meets the matching alarm conditions, an anti-theft alarm is triggered.

[0071] In this embodiment, optionally, if the matching alarm module 203 determines through comparison that the trigger time of the tension parameter data and the trigger time interval of the movement data to be registered are less than a preset time difference, and the data parameter value of the tension parameter data is determined to be greater than a preset tension threshold, and the data parameter value of the movement data to be registered satisfies a preset displacement relationship, then an anti-theft alarm is triggered if the comparison result satisfies the matching alarm conditions.

[0072] The technical solution provided in this embodiment identifies the target object based on a preset identifiable object in the image information; and obtains the registration displacement data based on the displacement data of the target object in each different image in the image information. By pre-setting identifiable objects, misidentification of other objects is prevented during the entire process. The trigger time and data parameter values ​​of the tension parameter data and the registration displacement data are compared. If the trigger time of the tension parameter data and the registration displacement data are consistent, and the data parameter value of the tension parameter data is greater than a preset tension threshold, and the data parameter value of the registration displacement data satisfies a preset displacement relationship, then the comparison result is determined to meet the matching alarm conditions, and an anti-theft alarm is triggered. By using multi-dimensional information matching to determine cable theft behavior, the monitoring efficiency of cable theft behavior is improved, while the false positive rate of cable theft behavior is reduced.

[0077] S303. If the comparison result meets the matching alarm conditions, trigger the burglar alarm.

[0078] In this embodiment, optionally, the step of identifying the target object in the image information to obtain the displacement data to be registered includes:

[0079] The target object is obtained by identifying the image information based on a preset identifiable object;

[0080] The displacement data to be registered is obtained based on the displacement data of the target objects in each different image in the image information.
