As an example, first, the data transmission module 4 described above may transmit data to the lora gateway. Next, the lora gateway may send the received data to an MQTT (Message Queuing Telemetry Transport) server through a router. Then, the MQTT server may transmit the received data to a WEB (global wide area network) server. Finally, the WEB server may store the received data. The WEB server may also send information for starting defense deployment monitoring to the data transmission module 4 through the MQTT server, the router, and the lora gateway in sequence. The storage module may be a module for storing data. For example, the memory module may be a memory chip. The battery module 5 may be a module for supplying power to the burglar alarm device without being connected to an external power source. For example, the battery module 5 may be a lithium battery.

Therefore, the data transmission module can transmit the relevant data of the anti-theft alarm device to other devices. The storage module can be used for storing the related data of the anti-theft alarm device. The battery module can supply power to the anti-theft alarm device under the condition of not being connected with an external power supply.
With continued reference to fig. 3, a flow 300 of some embodiments of a weighing-based burglar alarm method according to the present disclosure is shown. The anti-theft alarm method based on weighing comprises the following steps:
In some embodiments, an enforcement agent of the weight-based burglar alarm method (e.g., the weight-based burglar alarm device shown in fig. 1) may determine an initial item weight of a target item carried by the above-described burglar alarm device as well as indicator light status information. Wherein, the state information of the indicator light comprises defense deployment monitoring state information. The initial article weight may be article weight information previously stored by the burglar alarm arrangement. The initial article weight may be a weight detected by an associated high-precision weighing sensor when the target article is initially placed on the burglar alarm. The status information of the indicator light can represent the status of the anti-theft alarm device. The status information of the indicator light may include a defense monitoring status information. The arming monitoring state information may be information representing whether the anti-theft alarm device starts arming monitoring. For example, the defense deployment monitoring state information may be "defense deployment monitoring, open".
And 302, detecting the object weight of the target object through a high-precision weighing sensor included in the anti-theft alarm device.
In some embodiments, the execution body may detect the object weight of the target object by a high-precision load cell included in the burglar alarm apparatus.
In some embodiments, the execution agent may determine item weight change information based on the initial item weight and the item weight. In practice, the execution body may determine an absolute value of a difference between the initial article weight and the article weight as the article weight change information.
And 304, in response to the fact that the weight change information of the article meets the preset weight change threshold value condition and the defense deployment monitoring state information represents the defense deployment monitoring starting, controlling an alarm indicator lamp module included in the anti-theft alarm device to execute anti-theft alarm operation.
In some embodiments, the executing body may control an alarm indicator light module included in the burglar alarm device to execute an antitheft alarm operation in response to determining that the weight change information of the article meets a preset weight change threshold condition and the arming monitoring state information indicates that arming monitoring is on. The preset weight change threshold condition may be that an article weight change value corresponding to the article weight change information is greater than a preset weight change threshold. As an example, in response to determining that the article weight change information satisfies a preset weight change threshold condition and that the arming monitoring state information indicates that arming monitoring is on, the execution main body may control an indicator light corresponding to an alarm indicator light module included in the burglar alarm device to emit red light.
Optionally, the indicator light status information may further include alarm status information. The alarm state information may be information indicating whether the burglar alarm device is in the process of performing an burglar alarm operation. For example, when the burglar alarm device is in the process of performing burglar alarm operation, the alarm state information may be "alarm, turned on". When the anti-theft alarm device is not in the process of executing anti-theft alarm operation, the alarm state information can be 'alarm and not started'. And
optionally, the executing main body may further update the alarm state information to a state identifier representing that an anti-theft alarm operation is executed in response to determining that the article weight change information satisfies the preset weight change threshold condition and that the arming monitoring state information represents that arming monitoring is started. The status flag may be a flag indicating whether the burglar alarm device is performing an burglar alarm operation. For example, when the burglar alarm device is performing a burglar alarm operation, the state flag may be "0". When the burglar alarm device does not perform a burglar alarm operation, the state flag may be "1". As an example, the execution body may update the alarm state information to "0".
Optionally, the indicator light status information may further include network status information. The anti-theft alarm device also comprises a data transmission module and a storage module. The network state information may be information representing whether the burglar alarm apparatus is connected to a network. For example, when the burglar alarm device is connected to a network, the network status information may be "network, connected". When the anti-theft alarm device is not connected with the network, the network state information can be 'network, unconnected'. And
optionally, the executing body may further execute the following steps:
the first step, in response to the fact that the network state information represents that the anti-theft alarm device is connected with the network and the alarm state information meets the preset transmission condition, target transmission data are sent to the associated server through the data transmission module. Wherein, the target transmission data comprises the weight change information of the article, the defense deployment monitoring state information and the alarm state information. The preset transmission condition may represent that the burglar alarm device is in the operation of performing burglar alarm for the alarm state information.
And a second step of storing the target transmission data in the storage module in response to detection of transmission failure information corresponding to the target transmission data. The transmission failure information may be information indicating that the target transmission data is failed to be transmitted. For example, the transmission failure information may be "transmission failure of target transmission data". Specifically, the transmission failure information may be information generated by the execution agent when the target transmission data is not successfully transmitted. The transmission failure information may be information transmitted by the server when the target transmission data is successfully transmitted but the server does not successfully receive the target transmission data.
Optionally, the executing body may further store the target transmission data in the storage module in response to determining that the network state information indicates that the burglar alarm device is not connected to a network and that the alarm state information satisfies the preset transmission condition.
Optionally, the burglar alarm arrangement may further comprise an audible alarm. The sound alarm can be an alarm device which gives an alarm through sound signals. For example, the audible alarm may be a buzzer.
Optionally, the executing body may further control the acoustic alarm to execute an anti-theft acoustic alarm operation in response to determining that the article weight change information satisfies the preset weight change threshold condition and that the arming monitoring state information represents arming monitoring start. In practice, the execution main body can control the sound alarm to give out an alarm sound.
Optionally, the anti-theft alarm device may further include a camera, at least one first proximity sensor, and at least one second proximity sensor. And each first proximity sensor and each second proximity sensor are in communication connection with the camera device. The first proximity sensor may be a proximity sensor having a detection range within a first target range. The second proximity sensor may be a proximity sensor having a detection range within a second target range. Here, the specific type of the proximity sensor is not limited. Both the first target range and the second target range may be ranges preset around the burglar alarm device. For example, the first target range may be a range of 1 meter from the burglar alarm device. The second target range may be a range of 0.5 m from the burglar alarm device.
Optionally, the executing body may further execute the following steps:
the method comprises the steps of firstly, in response to the fact that any one of the at least one first proximity sensor detects that an obstacle exists in a first target range, controlling the camera device to shoot a scene in the first target range to obtain an obstacle image. The obstacle may be an object or a person.
And secondly, transmitting the obstacle image to an associated terminal. The terminal can be an intelligent device in communication connection with the anti-theft alarm device. For example, the terminal may be a smart phone.
And thirdly, controlling the alarm indicator lamp module to execute an anti-theft alarm operation in response to the fact that any second proximity sensor in the at least one second proximity sensor detects that an obstacle exists in a second target range. Wherein the second target range is smaller than the first target range. As an example, in response to determining that the article weight change information satisfies a preset weight change threshold condition and that the arming monitoring state information indicates that arming monitoring is on, the execution main body may control an indicator light corresponding to an alarm indicator light module included in the burglar alarm device to emit red light.
The first step to the third step are taken as an inventive point of the embodiment of the present disclosure, and a second technical problem mentioned in the background art that "it is impossible to detect whether a person approaches a protected object, which results in low security of the protected object" is solved. The reason for the low security of the article is as follows: it is not possible to detect whether a person is approaching the protected article. If the above factors are solved, the security of the article can be improved. In order to achieve the effect, the present disclosure first controls the image capturing device to capture a scene in a first target range to obtain an image of an obstacle in response to determining that any first proximity sensor of the at least one first proximity sensor detects that the obstacle exists in the first target range. Next, the above-described obstacle image is transmitted to the associated terminal. The terminal can be an intelligent device. And finally, in response to the fact that any second proximity sensor in the at least one second proximity sensor detects that an obstacle exists in the second target range, controlling the alarm indicator lamp module to execute anti-theft alarm operation. Wherein the second target range is smaller than the first target range. Therefore, when a person enters the first target range, the first target range can be shot and the image can be sent to the terminal of the worker. When personnel enter the second target range, the alarm can be given through the alarm indicator lamp module. Therefore, hierarchical monitoring can be realized, and the safety of the articles is improved.
Alternatively, the image pickup apparatus may include an image pickup assembly and a moving mechanism configured to control the image pickup assembly to move.
In some optional implementations of some embodiments, the executing body may control the image capturing device to capture the scene of the first target range by performing the following steps: and moving the camera assembly through the moving mechanism so as to control the camera assembly to shoot the target proximity area corresponding to any first proximity sensor. Wherein the target approaching area is located within the first target range. The target proximity region may be a region that can be sensed by the first proximity sensor.
The above steps are taken as an invention point of the embodiment of the present disclosure, and the technical problem mentioned in the background art is solved, namely, the third technical problem that people approaching the protected object cannot be accurately shot, thereby further causing the safety of the protected object to be low. The reason for further causing the low security of the article is as follows: people approaching the protected article cannot be accurately photographed. If the above factors are solved, the security of the article can be further improved. In order to achieve the above effect, the present disclosure moves the image pickup assembly through the moving mechanism to control the image pickup assembly to photograph a target proximity area corresponding to any of the first proximity sensors, wherein the target proximity area is located within the first target range. Therefore, when a person enters the target area, the camera shooting assembly can move and shoot the target area. Therefore, people close to the article can be shot accurately, and the safety of the article is further improved.
Optionally, the executing body may further execute the following steps:
the method comprises the following steps that firstly, in a preset time period, a target area is shot at intervals of preset duration through a related camera device, and a target area image set is obtained. Here, the specific settings of the preset time period, the interval preset time period, and the target area are not limited. As an example, the execution subject may capture an area of 2 meters around the burglar alarm apparatus at 7 to 12 points per day by the imaging device at intervals of 1 second, to obtain a target area image set.
And secondly, inputting each target area image in the target area image set into a pre-trained human body recognition model to obtain a human body recognition result set. Each human body recognition result in the human body recognition result set comprises a human body identification group. The human body recognition model may be a neural network model in which each target area image is used as input data and a human body recognition result set is used as output data. For example, the neural network model may be a convolutional neural network model or a deep neural network model. The human body recognition result may be a result including a mark corresponding to a human body image existing in the target area image. The human body identifier group may be a set of human body identifiers corresponding to human body images existing in each target area image.
