Based on the above-described prison security protection system, please refer to FIG. 1-2, which is a schematic flowchart diagram of a first embodiment of a method for preventing escape from a prison protection wall based on the Internet of Things according to an embodiment of the present invention. The method for preventing escape from the Internet of Things-based prison wall described in this embodiment includes the following steps:

101. The gateway acquires first vibration data for the protection wall by using multiple sensors, and the plurality of sensors are distributed on the protection wall. Surface or interior.

The sensor may be a vibration sensor, and a plurality of vibration sensors may be disposed on the surface or inside the protective wall. The plurality of sensors are respectively located in different areas of the protective wall. When the protective wall is attacked by the outside world, for example, the external attack may be a prisoner. When you escape from prison, climb, hit the protective wall, or dig holes in the protective wall, the bottom of the protective wall, etc., no matter how the prisoner attacks the protective wall, the protective wall will have severe vibration, and the gateway can pass more The sensors acquire first vibration data for the protective wall.

Optionally, the foregoing step 101 may include the following steps:

11) acquiring the plurality of vibration data from the plurality of sensors;

12) determining, according to the plurality of vibration data, the vibration source position;

13) selecting at least one sensor closest to the position of the vibration source as the target vibration sensor, and using the vibration data as the first vibration data.

Optionally, since the protection wall is provided with a plurality of sensors, vibration data of various parts of the protection wall can be obtained from the plurality of sensors, and the position of the vibration source can be determined according to the plurality of vibration data. Because when the protective wall is attacked by the outside world, the external attack is concentrated in an area of the protective wall. When the vibration data in the vibration sensor in this area is not attacked, the change is larger and can be more realistic. The vibration of the ground reaction wall. Since the variation of the vibration data in the vibration sensor farther from this region is smaller, the change of the vibration data closer to the vibration source is more remarkable, and therefore the position of the vibration source can be determined based on the vibration data. After determining the position of the vibration source, at least one vibration sensor closest to the vibration source is used as the target sensor, and the vibration data acquired from the target sensor may be used as the first vibration data.

102. The gateway compares the first vibration data with the second vibration data.

Wherein, the first vibration data and the second vibration data are compared, and if the comparison is successful, the alarm system may be triggered to issue an alarm, thereby informing the prison police that someone may be attacking the protective wall at this time.

Optionally, the foregoing step 102 may include the following steps:

21) converting the first vibration data into a vibration trajectory;

22) extracting a total time in which the vibration amplitude is greater than a first preset threshold;

23) determining whether the total time is greater than a second preset threshold, and confirming that the first vibration data and the second vibration data are successfully compared when the total time is greater than the second preset threshold.

Alternatively, when the first vibration data and the second vibration data are compared, the first vibration data may be first converted into a vibration trajectory. The vibration trajectory may be a vibration image, and the vibration amplitude of the protection wall with the vibration time may be known from the vibration image, and the total time of the vibration amplitude greater than the first preset threshold is obtained from the vibration trajectory, and whether the total time is greater than the second pre-determination Set the threshold, the total time is greater than the second preset At the threshold, it is confirmed that the first vibration data and the second vibration data are successfully aligned.

Optionally, when the vibration amplitude is greater than the first preset threshold, the vibration of the protective wall is severe at this time. When the total time of the vibration amplitude greater than the first preset threshold is greater than the second preset threshold, the protective wall not only has a severe vibration, And the time of violent vibration is still very long. At this time, it can be judged that someone may be attacking the protective wall. For example, when a prisoner is climbing a protective wall, it takes a certain time, so the protective wall not only has severe vibration but also vibration. Time will also be on the scene. According to the vibration amplitude and vibration time of the protective wall, it is judged that some accidents are avoided, such as someone accidentally hitting the protective wall, something falling on the protective wall, etc., which is mistakenly determined as a human attack.

Optionally, the first vibration data is converted into a vibration trajectory, and the sampling time of the first vibration data may be determined according to the stability of the first vibration data, and the stability of the first vibration data is higher, and the corresponding first vibration data is The longer the sampling time can be. The first vibration data is sampled in units of sampling time, thereby obtaining a plurality of time-sampling vibration data, wherein the plurality of time-sampling vibration data includes a vibration time and a vibration amplitude, and the vibration time is sampled according to the plurality of times, and the vibration time is The X-axis, the vibration amplitude is the Y-axis, the vibration trajectory of the plurality of time-sampling vibration data is plotted, and the vibration trajectory of the first vibration data is determined according to the vibration trajectory of the plurality of time-sampling vibration data.

103. The gateway triggers an alarm system to issue an alarm when the comparison between the first vibration data and the second vibration data is successful.

Wherein, when the first vibration data and the second vibration data are successfully matched, the gateway can confirm that the protection wall has received an attack, and can trigger the alarm system to issue an alarm. The alarm system can include a variety of alarm devices in the prison, such as alarm bells, broadcasts, warning lights, horns, and the like.

Optionally, the foregoing step 103 may include the following steps:

31) determining an alarm level corresponding to the total time according to a total time when the vibration amplitude is greater than the first preset threshold in the vibration trajectory;

32) determining, according to the alarm level, an alarm device identifier in the alarm system corresponding to the alarm level;

33) determining an alarm device that issues an alarm in the alarm system according to the alarm device identifier, and controlling the alarm device to issue an alarm.

Wherein, the level of the alarm may be determined according to the total time of the vibration trajectory in which the vibration amplitude is greater than the first preset threshold. The longer the total time, the higher the level of the alarm should be. Because the longer the total time, the closer the prisoner may escape from the prison through the protective wall, the more urgent it is. Therefore, the alarm level can be increased by one level for every ten minutes of total time increase, and the police officer can be urged to speed up the action by increasing the alarm level.

Optionally, different alarm levels may have different alarm devices in the alarm system, and corresponding alarm devices may issue alarms. Therefore, different alarm levels are required to correspond to different alarm device identifiers, and the current alarm level is determined. Then, according to the alarm device identifier corresponding to the alarm level, the alarm device corresponding to the control alarm device identifier issues an alarm. For example, the current alarm level is 1 level, indicating that the situation has not reached a very serious level. In order to avoid causing panic in the prison, it is only possible to use the warning light to report the alarm, without broadcasting through the radio or the horn. When the alarm level is 1 level, it corresponds to the identifier of the alarm light device, and the gateway controls the alarm according to the identification of the alarm light device. The light flashes, so you can notify the police officer that an emergency has occurred.

It can be seen that, by using the plurality of sensors, the first vibration data for the protection wall is distributed by the plurality of sensors, the plurality of sensors being distributed on the surface or the inside of the protection wall; and the first vibration data and the second The vibration data is compared; when the first vibration data is successfully aligned with the second vibration data, the alarm system is triggered to issue an alarm. Therefore, the probability of prisoners serving prisoners escaping from prison through the protective wall can be reduced, and the safety of the prison protective wall can be improved.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart diagram of a second embodiment of a method for preventing escape from a prison wall based on the Internet of Things according to an embodiment of the present invention. As shown in FIG. 2, a method for preventing escape from a prison wall based on the Internet of Things provided by the embodiment of the present invention may include:

201. The gateway sends a first vibration data acquisition request to the sensor.

The first vibration data acquisition request carries a sensor number or serial number information, a gateway number or serial number information. When the sensor number or serial number information in the first vibration data acquisition request matches the number or serial number information of the sensor itself, the sensor receives the first vibration data acquisition request sent by the gateway, and the gateway number or serial number information is used. Identify the identity of the gateway.

Optionally, in some possible implementation manners of the present invention, the gateway may determine, according to a current time, a frequency of sending the first vibration data acquisition request to the sensor. The frequency of transmitting the first vibration data acquisition request to the sensor may be increased within a preset time period, or the frequency of transmitting the first vibration data acquisition request to the sensor may be reduced. For example, every day from 12 noon to 2 o'clock in the afternoon, the lunch break for the prisoners, during this time period everyone is in the lunch break, relatively lax, the prisoners to implement the escape plan is more frequent, or, at night Sleep time, from 10:00 pm to 6:00 am, is also the high frequency period of the escape event, which can be set to the preset time. When the gateway determines that the current time belongs to the preset time, the frequency of sending the first vibration data acquisition request to the sensor may be increased, thereby enhancing the security detection of the prison protection wall; and when the gateway determines that the current time does not belong to the preset time, the gateway may be reduced. The frequency of the first vibration data acquisition request is sent to the sensor, thus reducing the workload of the gateway and the sensor.

Optionally, after sending the first vibration data acquisition request to the sensor, the gateway waits for the sensor to send the first vibration data, and the waiting time is within a preset duration. If the first vibration data sent by the sensor is not received within the preset duration, The gateway will perform a first vibration data acquisition request to the sensor again.

Alternatively, the preset duration may be 1 second, 2 seconds, 3 seconds, 4 seconds, 5 seconds, or other time.

202. After receiving the first vibration data acquisition request, the sensor acquires first vibration data for the protection wall.

When receiving the first vibration data acquisition request, the sensor may determine whether to receive the first vibration data acquisition request according to the sensor number or serial number information carried in the first vibration data acquisition request, and according to the first vibration data. Obtain the gateway number or serial number information carried in the request, and determine whether to send the first vibration data to the gateway.

Optionally, the sensor may first send a first vibration data acquisition response to the gateway, and the first vibration sent by the gateway is received to the gateway surface. The data acquisition request, or the sensor can send the first vibration data directly to the gateway.

203. The sensor sends the first vibration data to the gateway.

After acquiring the first vibration data for the protection wall, the sensor may send the first vibration data to the gateway, and before the sensor sends the first vibration data to the gateway, the current load value of the gateway may be obtained first, and the current load value of the gateway. When the preset load value is greater than the gateway, the sensor can wait in a queue. When the current load value of the gateway is less than the preset load value, the first vibration data is sent to the gateway.

204. The gateway acquires first vibration data sent by a sensor for a protective wall.

The first vibration data may be more than one, and may be multiple.

205. The gateway compares the first vibration data with the second vibration data.

The gateway compares the first vibration data with the second vibration data. If the comparison is successful, the alarm system may be triggered to issue an alarm, thereby informing the prison police that someone may be attacking the protective wall at this time.

Optionally, when the gateway compares the first vibration data and the second vibration data, the first vibration data may be first converted into a vibration trajectory. The vibration trajectory may be a vibration image, and the vibration amplitude of the protection wall with the vibration time may be known from the vibration image, and the total time of the vibration amplitude greater than the first preset threshold is obtained from the vibration trajectory, and whether the total time is greater than the second pre-determination A threshold is set, and when the total time is greater than the second preset threshold, it is confirmed that the first vibration data and the second vibration data are successfully aligned.

Optionally, converting the first vibration data into a vibration trajectory, and sampling the first vibration data in time, obtaining a plurality of time-sampling vibration data, and sampling the vibration data according to the plurality of times to obtain a wall of the protective wall The vibrational trajectory of the body.

206. The gateway triggers an alarm system to issue an alarm when the comparison between the first vibration data and the second vibration data is successful.

Wherein, when the gateway compares the first vibration data and the second vibration data successfully, the gateway can confirm that the protection wall receives the attack, and can trigger the alarm system to issue an alarm. The alarm system can include a variety of alarm devices in the prison, such as alarm bells, broadcasts, warning lights, horns, and the like.

Optionally, the level of the alarm may be determined according to a total time in the vibration trajectory where the vibration amplitude is greater than the first preset threshold. The longer the total time, the higher the level of the alarm should be. Because the longer the total time, the closer the prisoner may escape from the prison through the protective wall, the more urgent it is. Therefore, the alarm level can be increased by one level for every ten minutes of total time increase, and the police officer can be urged to speed up the action by increasing the alarm level.

Optionally, different alarm levels may have different alarm devices in the alarm system, and corresponding alarm devices may issue alarms. Therefore, different alarm levels are required to correspond to different alarm device identifiers, and the current alarm level is determined. Then, according to the alarm device identifier corresponding to the alarm level, the alarm device corresponding to the control alarm device identifier issues an alarm. For example, the current alarm level is 1 level, indicating that the situation has not reached a very serious level. In order to avoid causing panic in the prison, it is only possible to use the warning light to report the alarm, without broadcasting through the radio or the horn. When the alarm level is 1 level, it corresponds to the identifier of the alarm light device. The gateway controls the alarm light to flash according to the identification of the alarm light device. In this way, the police officer can be notified that an emergency situation occurs at this time.

207. The gateway determines M cameras within a preset range with the vibration source position as an origin according to a vibration source position, where the M is an integer greater than 1.

Among them, in the vicinity of the prison protective wall, multiple cameras can be set up, so that the situation near the prison protective wall can be monitored, but only through the camera monitoring, it can not effectively ensure that there is a prisoner attacking the protective wall in time because The camera has a blind corner area, and at night, or when the weather is bad, the surrounding area of the protective wall cannot be clearly captured. Therefore, when it is determined that a person may be attacking the protective wall, the gateway determines the M cameras within a preset range whose origin is the origin of the vibration source position according to the vibration source position.

208. The gateway instructs the M cameras to perform a photographing operation respectively.

Wherein, after determining M cameras within a preset range whose origin is the origin of the vibration source position, the gateway may instruct the M cameras to perform a photographing operation.

209. The M cameras perform a photographing operation, and send the photographed K photos to the gateway, where K is an integer greater than the M.

Among them, M cameras can take K photos, K can be an integer greater than M, because a camera can take more than one photo, can take multiple photos, and thus get K photos.

210. The gateway acquires K photos taken by the M cameras.

After obtaining the K photos, the gateway can detect the sharpness of the K photos, compare the sharpness of the K photos with the third preset threshold, and select the sharpness from the K photos to be greater than the third preset threshold. N photos.

211. The gateway selects, in the K photos, N photos whose resolution is greater than a third preset threshold, where N is an integer smaller than the K, and compresses the N photos, and then compresses the N photos. The N photos are sent to the designated mobile terminal.

Optionally, after the gateway selects N photos with a resolution greater than a third preset threshold from the K photos, the gateway may send the N photos to the designated mobile terminal.

Optionally, the gateway may compress the N photos and send them to the designated mobile terminal, because the resolution of the N photos is high, because Therefore, after the compression, the captured content can be seen more clearly. After the mobile terminal receives the compressed N photos, it can also change the original photo to view the original image.

Optionally, the designated mobile terminal is carried by the police officer of the prison. After the gateway sends the N photos to the designated mobile terminal through the server, after the police officer hears the alarm, the police officer can view the photo on the mobile terminal to determine the current alarm system. Is it a false alarm?

It can be seen that, by using the embodiment of the present invention, the gateway sends a first vibration data acquisition request to the sensor; after receiving the first vibration data acquisition request, the sensor acquires first vibration data for the protection wall; the sensor Transmitting the first vibration data to the gateway; the gateway acquiring first vibration data sent by a sensor for a protective wall; the gateway comparing the first vibration data with second vibration data; The gateway triggers the alarm system to issue an alarm when the first vibration data and the second vibration data are successfully matched; the gateway determines, according to the vibration source position, the M in the preset range with the vibration source position as the origin. a camera, the M is an integer greater than 1; the gateway instructs the M cameras to perform a photographing operation respectively; the M cameras perform a photographing operation, and send the photographed K photos to the gateway, the K An integer greater than the M; the gateway acquires K photos taken by the M cameras; the gateway selects a resolution greater than a third preset in the K photos Photos value N, the N is an integer less than the K, and the N pictures is compressed, the compressed pictures N to a given mobile terminal. Therefore, the probability of prisoners serving prisoners escaping from prison through the protective wall can be reduced, and the safety of the prison protective wall can be improved.
