The following describes methods of use according to embodiments of the present application with reference to the accompanying drawings.

Referring to fig. 2, a method for predicting behavior based on signal detection according to an embodiment of the present application is applied to a server of a management platform of a system for predicting behavior based on signal detection, where the system may include a code detection device, a ship monitoring device, and a management platform, where the management platform is communicatively connected to the code detection device and the ship monitoring device, and the method may include the following steps:

S201, controlling the code detection equipment to collect the user identification codes of the mobile terminals in a first preset range according to a first preset period.

Specifically, a worker (or a user) may use the management platform through the user terminal, and set a specific value of the first preset period on the management platform. More, the staff (or the user) can also directly set the specific value of the first preset value period on the detecting device. A user terminal may also be referred to as a terminal device, and may be stationary or mobile. The specific form of the mobile phone can be a mobile phone (mobile phone), a tablet personal computer (Pad), a computer with a wireless receiving and transmitting function or a wearable terminal device. The operating system of the terminal equipment at the PC end, such as an all-in-one machine, may include, but is not limited to, an operating system such as a Linux system, a Unix system, a Windows series system (e.g., windows xp or Windows 7, etc.), or a Mac OS X system (operating system of an apple computer). The operating system of the terminal device of the mobile terminal, such as a smart phone, may include, but is not limited to, an operating system such as an android system, an IOS (operating system of an apple phone), or a Window system.

For example, if the staff (or the user) sets the first preset period to 1 second on the management platform through the user terminal, the management platform will send a data acquisition instruction (for instructing the detection code device to acquire the user identification code of the mobile terminal) to the detection code device every 1 second, and receive the data returned by the detection code device (such as the user identification code of the mobile terminal). Or, the management platform may send the value of the first preset period (i.e. 1 second) to the code detection device, where the code detection device may collect the user identification code of the mobile terminal in the first preset range once every 1 second, and send the user identification code to the management platform.

More, the first preset range is related to an operation mode of the code detection device, and the operation mode of the code detection device may include a high power consumption mode and a low power consumption mode, where a detection range covered by the high power consumption mode (i.e., the first preset range) is greater than a detection range covered by the low power consumption mode (i.e., the first preset range), and/or a first preset period corresponding to the high power consumption mode is less than a first preset period corresponding to the low power consumption mode. The first preset range corresponding to the low power consumption mode may be a circular area with the detection device as a center and a diameter of 10 km, and the first preset range corresponding to the high power consumption mode may be a circular area with the detection device as a center and a diameter of 20 km; or, if the first preset period corresponding to the low power consumption mode is 1 minute, the first preset period corresponding to the high power consumption mode may be 30 seconds.

S202, judging whether a target terminal exists according to the user identification code, wherein the target terminal is a terminal of which the user identification code does not belong to a mobile terminal white list.

It should be noted that the target terminal may be a terminal whose user identification code does not belong to the mobile terminal whitelist. The whitelist may be set by a worker and saved in the management platform.

For example, if the code detection device collects the user identification codes of the first mobile terminal, the second mobile terminal and the third mobile terminal in the first preset range, and can query the user identification codes of the first mobile terminal and the third mobile terminal in the mobile terminal white list, it can be determined that the second mobile terminal is the target terminal.

And S203, if the target terminal exists, calculating a first distance between the position of the target terminal and the target position.

The management platform can calculate or determine the position of the target terminal according to the signal intensity of the target terminal acquired by the detection code device, and the data corresponding to the user identification code of the target terminal sent to the management platform by the detection code device can contain the information of the signal intensity of the target terminal.

More, the target position may be the position of the code detection device, or may be the center point of a preset area (such as a cultivation water area), etc.

And S204, when the first distance is larger than a first preset value, controlling the ship monitoring equipment to acquire ship information in a preset area.

It should be noted that the ship information may include the position of the ship and the identity information of the ship, and may also include the number of ships. The collection of ship information may be implemented based on an automatic ship identification system (Automatic Identification System, abbreviated as AIS system).

For example, when the first distance is greater than the first preset value, it may indicate that the suspicious person (i.e. the owner of the target terminal) is in the open sea water area, and then the suspicious person may have the ship to travel to the preset area (i.e. the cultivation water area) to perform suspected theft, so that the ship information in the preset area is collected, which is helpful to more timely and accurately detect the suspicious person and the suspicious ship, and further improves the anti-theft efficiency.

S205, judging whether a target ship exists according to the ship information.

It should be noted that the target ship may be a ship whose identity information does not belong to the ship whitelist. The whitelist may be set by a worker and saved in the management platform.

For example, if the ship monitoring device collects the ship information of the first ship, the second ship and the third ship in the preset area, and can inquire the identity information of the second ship and the third ship in the ship white list, it may be determined that the first ship is the target ship.

S206, if a target ship exists and the positions of the target ship and the target terminal are the same, controlling the ship monitoring equipment to monitor the moving state of the target ship according to a second preset period, controlling the code detection equipment to collect the user identification code of the target terminal according to the second preset period, and calculating the moving state of the target terminal according to the user identification code of the target terminal.

The movement state includes a movement direction and a movement speed.

More, in view of the error problem of the positioning technology, when the target ship exists and the distance between the target ship and the target terminal is kept within a certain range, the ship monitoring device can be controlled to monitor the moving state of the target ship according to the second preset period, the detecting device can be controlled to collect the user identification code of the target terminal according to the second preset period, and the moving state of the target terminal can be calculated according to the user identification code of the target terminal.

Exemplary, case one: in the preset area, a first target ship and a first target terminal exist, and the positions of the first target ship and the first target terminal relative to the target position are the same, for example, the first target ship and the first target terminal are both positioned at the position which is 20 degrees in the southwest direction of the target position and 8 kilometers away from the target position; or the longitude and latitude coordinates of the first target ship and the first target terminal are the same. And a second case: in the preset area, a second target ship and a second target terminal are arranged, wherein the second target ship and the second target terminal are both positioned in the direction of 20 degrees in the southwest of the target position, but the second target ship is 7 kilometers away from the target position and the second target terminal is 6.95 kilometers away from the target position, and the positions of the second target ship and the second target terminal are considered to be the same under the condition that the distances between the second target ship and the second target terminal are only 50 meters; or the second target ship is located in the 19-degree southwest direction of the target position, the second target terminal is located in the 20-degree southwest direction of the target position, the second target ship is 7 km away from the target position, the second target terminal is 7 km away from the target position, and only a slight difference exists between the second target ship and the target position in the direction, and the positions of the second target ship and the second target terminal can be considered to be the same in the case; or the second target ship is positioned in the 19-degree direction of the southwest of the target position, the second target terminal is positioned in the 20-degree direction of the southwest of the target position, the second target ship is 7 kilometers away from the target position, the second target terminal is 6.97 kilometers away from the target position, and the distance difference and the direction difference between the second target ship and the second target terminal are smaller, so that the second target ship and the second target terminal can be considered to be the same in position; alternatively, the difference between the longitude and latitude coordinates of the second target ship and the second target terminal is also within a certain range. It should be noted that, the position error range (including the difference of the distance and the difference of the direction) of the target ship and the target terminal is set by a technician and/or a staff, and the embodiment of the present application only describes the method of the embodiment of the present application in more detail, and the above examples of the position and the direction should not limit the present application.

And S207, when the target ship and the target terminal stop moving at the same time and the time for stopping moving is larger than a second preset value, determining that suspected theft exists.

Possibly, if the target ship stops moving and the target terminal keeps moving all the time, but the distance between the target terminal and the target ship is kept within a certain range when the target terminal moves, after determining that the time for stopping moving the target ship is greater than a second preset value, the suspected theft can be determined.

For example, if the third target ship and the third target terminal are present, it is monitored that the third target ship has not moved for more than 8 minutes (the second preset value is set to 5 minutes), but the third target terminal is always in a moving state, and the moving range of the third target terminal does not exceed 20 meters of the square circle of the third target ship, the third target terminal may be considered to be moving on the third target ship, and suspected theft may be considered to exist. The "square and round 20 meters" is not true, and indicates that the movable range provided by the third target ship to the third target terminal is greater than or equal to 20 meters, which is a corresponding determination range given by considering the positioning error and the ship size (used for assisting in determining whether there is suspected theft), and the moving atmosphere of the target terminal may be set by a technician and/or a staff according to the actual situation, and the "20 meters" is only for illustrating the method of the embodiment of the present application in more detail, and should not be limited.

Referring to fig. 3, a schematic diagram of a scenario for determining a target ship and a target terminal according to an embodiment of the present application is shown. As shown in fig. 3, there are a ship 1, a ship 2, and a ship 3 in the target area 310, and there are a mobile terminal 1, a mobile terminal 2, and a mobile terminal 3. Let the distance between the ship 1, the ship 2, the mobile terminal 1 and the mobile terminal 2 be smaller than the above-mentioned judgment range (i.e., the distance range related to the positioning error, as above, "square circle of 20 m" between the target terminal 3 and the target ship 3 is a judgment range), the ship 1 moves to the east, the ship 2 moves to the west, the ship 3 moves to the east, the mobile terminal 1 moves to the east, the mobile terminal 2 moves to the west, and the mobile terminal 3 moves to the east. By analyzing the moving states of the ship and the mobile terminal, the corresponding relationship between the mobile terminal 1 and the ship 1, the corresponding relationship between the mobile terminal 2 and the ship 2, and the corresponding relationship between the mobile terminal 3 and the ship 3 can be obtained by taking the mobile terminal 1 and the mobile terminal 2 as target terminals and taking the ship 1 and the ship 3 as target ships. Since the mobile terminal 3 is not the target terminal, monitoring of the ship 3 can be canceled according to the correspondence; since the ship 2 is not the target ship, the monitoring of the mobile terminal 2 can be canceled according to the correspondence; since the mobile terminal 1 belongs to the target terminal and the ship 1 is the target ship, the mobile terminal 1 and the ship 1 need to be continuously monitored.

It should be noted that, there may be a case where two or more target terminals exist in the same target ship, and for this case, the process of determining the target ship and the target terminal may refer to the process described in fig. 3, which is not described herein. S208, generating first warning information and sending the first warning information to the target ship and/or the target terminal.

It should be noted that, the first warning information may be used to inform the target terminal and/or the person corresponding to the target ship to leave the preset area.

The first warning message may be, for example, a message similar to "this area belongs to a private aquaculture area, you are now monitoring for a stay time in this area of more than 10 minutes, you leave this area westernly".

Furthermore, the management platform can also control the warning device (such as a laser lamp, a loudspeaker and the like) to take warning measures. For example, a laser lamp is irradiated to the position (or direction) where the target terminal and/or the target ship are/is located, or a loud speaker is used for broadcasting the first warning information so as to achieve the purpose of driving suspected thieves.

S209, generating first alarm information and sending the first alarm information to staff.

It should be noted that, the first alarm information may include identity information and location information of the target ship, and/or user identification code and location information of the target terminal, and the first alarm information may be used to inform a worker that there is a suspected theft in the preset area.

By way of example, the first alert message may be similar to "there is suspected theft 15 ° north west from the target location, ship number xxx". Wherein, the management terminal can achieve the alarm purpose by sending alarm information to the user terminal of the staff (or the user).

Further, the management platform may also send the first alert information to a preset public security authority (which may be a nearest dispatch office or the like from the target location). For example, when there is a fourth target terminal and a fourth target ship at a position 30 ° in the west of the target position, an alarm message similar to "there is a fourth target terminal (user identification code is xxxx) and a fourth target ship (ship code is xxx) at a position 30 ° in the west of the target position is being subjected to suspected theft, please go to a stop" may be transmitted to the first dispatch place (the dispatch place closest to the target position is set as the first dispatch place).

It can be seen that the embodiment of the application can provide diversified warning/warning means, and is helpful to improve the efficiency and effect of preventing suspected theft.

Specifically, when the first distance is smaller than or equal to the first preset value, it may be indicated that the suspicious person (i.e. the owner of the target terminal) is in the offshore water area, and then the suspicious person may drive or ride a vehicle similar to a motorcycle to go to the target area (i.e. the aquaculture water area), and then suspected theft is implemented, so that the moving state of the target terminal needs to be continuously monitored, and whether the suspected theft exists in the owner of the target terminal is further determined, which is helpful for improving the accuracy and timeliness of the theft judgment and providing more reliable theft protection for the aquaculture water area.

Further, when it is determined that the target terminal exists, a second preset period smaller than the first preset period may be selected. For example, if the first preset period is 1 second, the second preset period may be set to 0.5 second, which is helpful for obtaining the movement information of the target terminal more timely. The setting manner of the second preset period may refer to the setting manner of the first preset period, which is not described herein.

The calculation and/or determination of the position and the movement state of the target terminal are the same as those described in steps S203 to S207 and the embodiments thereof, and are not described herein. More, the content and the receiving object of the second alarm and the second alarm are the same as those in steps S208 to S209 and related embodiments, and are not described herein.

In one possible implementation manner, after the control code detecting device obtains the user identification code of the target terminal according to the second preset period when the first distance is smaller than or equal to the first preset value, the method may further include the following steps:

For example, if the target terminal is kept moving all the time, it may be considered that the user of the target terminal does not perform suspected theft, so that the monitoring of the target terminal may be released after the first distance is greater than the first preset value; if the target terminal stops moving at a position within the first preset range and the stop time is 6 minutes, the second preset value is set to 10 (minutes), the user of the target terminal may be considered to have not performed suspected theft, and thus the monitoring of the target terminal may be released after the first distance is greater than the first preset value.

Fig. 4 is a schematic diagram of a scenario for determining a target terminal according to an embodiment of the present application. As shown in fig. 4, there are mobile terminal 4 (distance from target position 420 is 2 km), mobile terminal 5 (distance from target position 420 is 2 km), and mobile terminal 6 (distance from target position 420 is 1 km) within first range 410, wherein mobile terminal 4 is kept stationary for 30 minutes (set to a second preset value of 5 minutes), mobile terminal 5 is kept moving straight at a uniform velocity in the south, mobile terminal 6 is stationary for 3 minutes and then moves at a uniform velocity in the east. If the first preset value is set to be 3 km, the management platform queries whether the user identification codes of the mobile terminal 4, the mobile terminal 5 and the mobile terminal 6 acquired by the code detection device exist and move the white list, and if only the user identification codes of the mobile terminal 4 exist and move the white list of the mobile terminal, the mobile terminal 5 and the mobile terminal 6 are judged to be target terminals. If the mobile terminal 5 is found to keep moving until the distance from the target position 420 is more than 3 km through monitoring, the monitoring of the mobile terminal 5 is released after the distance from the mobile terminal 5 to the target position 420 is more than 3 km; if it is found by monitoring that the mobile terminal 6 has been moved south to a position more than 3 km away from the target position 420 after being kept stationary for 3 minutes, the monitoring of the mobile terminal 6 can be released after the mobile terminal 6 is more than 3 km away from the target position 420.

Further, the above-mentioned two different monitoring modes (or means) for the case where the first distance is greater than the first preset value and the first distance is less than or equal to the first preset value may be performed simultaneously, and the two monitoring modes (or means) do not conflict.

It can be seen that when the first distance is smaller than or equal to the first preset value, different monitoring means are adopted in the embodiment of the application, so that the pertinence of monitoring is stronger, and the accuracy of identifying suspected theft is improved.

In one possible implementation manner, the method according to the embodiment of the present application may further include the following steps:

Further, the suspected theft information may further include identity information of the target ship corresponding to the suspected theft.

In particular, the suspected theft function may be used to represent the probability of suspected theft occurring at various times of the day.

In another possible implementation manner, the method according to the embodiment of the present application may further include the following steps:

More, the working modes of the code detection device may further include a middle power consumption mode, a detection range covered by the middle power consumption mode is located between a detection range covered by the high power consumption mode and a detection range covered by the low power consumption mode, and/or a first preset period corresponding to the middle power consumption mode is located between a first preset period corresponding to the low power consumption mode and a first preset period corresponding to the high power consumption mode. For example, if the detection range covered by the high power consumption mode is an area with a diameter of 20 km centered on the target position, and the detection range covered by the low power consumption mode is an area with a diameter of 5 km centered on the target position, the detection range covered by the medium power consumption mode may be an area with a diameter of 10 km centered on the target position; or, if the first preset period corresponding to the high power consumption mode is set to be 30 seconds and the first preset period corresponding to the low power consumption mode is set to be 1 minute, the first preset period corresponding to the medium power consumption mode may be 45 seconds.

By way of example, if the theft function is displayed at 21 per day: the probability of suspected theft occurring between 00 and 2:00 of the next day was 70%, at 6: the probability of suspected theft during the period of 00 to 12:00 is 5%, at 13: the probability of suspected theft in the time of 00 to 14:00 is 20 percent, and the probability can be 21 percent per day: the detection device is put into a high power consumption mode for a period of 00 to 2:00 of the next day, at 6: the 00-12:00 period enables the code detection device to be in a low power consumption mode, and the code detection device is in a 13:00 to 14:00 places the detection device in a medium power mode.

It should be noted that, the foregoing examples of the detection ranges and/or the first preset periods of the coverage of the high power consumption mode, the middle power consumption mode and the low power consumption mode and the occurrence probability of the suspected theft in different periods are only for more vividly describing the method of the embodiment of the present application, and should not limit the present application, and the specific relevant coverage detection ranges are set by technicians and/or staff according to actual situations, which is not limited herein.

It can be seen that the embodiment of the application can adjust the working efficiency of the code detection equipment according to the probability of suspected theft in different time periods, and reduces the anti-theft cost while not affecting the accuracy of the theft identification.

and sending the third alarm information to the staff member.

The management platform may send the third alarm information to the staff and/or the public security mechanism and/or use other alarm means when the detection device detects that the fifth mobile terminal is in the first preset range; if the identity information of the fifth ship exists in the ship blacklist, the management platform can send third alarm information to staff and/or public security institutions and/or adopt other alarm means when the ship monitoring equipment monitors that the fifth ship appears in the first preset range. The content of the third alarm information and the receiver may refer to the related content of the first alarm information and the second alarm information, which are not described herein.

Further, after receiving the third alarm information, the worker may choose to ignore the third alarm information according to the actual situation. For example, after confirming that the user (or owner) of the fifth mobile terminal is currently a trusted person, the staff member may manually release the alarm, or may save the identity information of the fifth mobile terminal in the mobile terminal whitelist. Similarly, the staff can confirm that the personnel on the fifth ship are all trusted personnel, so that the alarm can be manually released, and the identity information of the fifth ship can be stored in the ship white list.

It can be seen that the method of the embodiment of the application can adopt different anti-theft monitoring means according to different suspicious conditions, so that the monitoring is more targeted, the accuracy of anti-theft identification is improved, and a better anti-theft effect is obtained. The embodiment of the application can also obtain a more scientific suspected theft function by analyzing the suspected theft data, thereby being beneficial to adopting the equipment working efficiency which is more in line with the actual situation, reducing the theft-proof cost and simultaneously keeping a better theft-proof effect. More, the embodiment of the application can also utilize the blacklist (the blacklist of the mobile terminal and/or the blacklist of the ship) to carry out quick judgment, thereby being beneficial to shortening the identification time of suspected theft and enabling the theft to be more efficient.
