step S11, a password target tracking device is worn for the criminal suspect, the target tracking device collects the biological characteristics and the action characteristics of the criminal suspect according to the appointed time interval, and the biological rules and the action rules of the criminal suspect in each time period every day are obtained through statistical analysis.
Specifically, the functions of the target tracking device are divided into two categories, one is to collect biological characteristics of a criminal suspect, such as blood pressure, pulse, respiration, voice, body temperature, and the like; another type is to collect the action characteristics of the criminal suspect, such as geographic location, speed, acceleration, direction of action, etc. By combining the two types of characteristics, a data base can be provided for predicting the current state of the criminal suspect.
In addition, the biological characteristics and the action characteristics of the criminal suspect can be analyzed by adopting a time series analysis algorithm to obtain the biological rules and the action rules of the criminal suspect in each time period. For example, it is found through analysis that a criminal suspect runs around a cell at 6 am, the average pulse is 120, and on the basis of the rule, if the criminal suspect is not moving around the cell and has only 60 pulses on a certain day, the criminal suspect may escape, and a warning should be given to a supervisor.
In one embodiment, the acquiring, by the target tracking device, the biological characteristics and the behavior characteristics of the criminal suspect at specified time intervals, and obtaining the biological rules and the behavior rules of the criminal suspect in each time period every day through statistical analysis includes:

and collecting the geographical position of the criminal suspect every 10 minutes by taking 24 hours as a period, and carrying out cluster analysis on the geographical position collected every time to obtain the action rule.
And S12, when the criminal suspect moves, the target tracking device searches for public security points within a specified distance range through broadcasting, and sends the biological characteristics and the action characteristics to at least two public security points in the public security points according to specified time intervals.
For example, when only a single public security network performs target tracking, on one hand, communication may fail and tracking of a criminal suspect will be unstable; on the other hand, two or more public security points track the criminal suspect together, and can carry out data calibration, thereby making the monitoring data more accurate.
In one embodiment, the target tracking device searches for public security sites within a specified distance range by broadcasting, and transmits the biometric characteristic and the action characteristic at specified time intervals with at least two public security sites of the public security sites, including:
the first public security point obtains the position of a first criminal suspect through communication with the tracking equipment;
the second public security network obtains the position of a second criminal suspect through communication with the tracking equipment;
the first security website is communicated with the second security website, the position of the first criminal suspect and the position of the second criminal suspect are calibrated, and the geographic position of the criminal is obtained.

In particular, in the judicial view, the fact that a supervisor should have sufficient evidence to prove if a criminal suspect escapes, makes it necessary to record and evidence the environment around the criminal suspect. The recording may be performed by a microphone and camera mounted on the wearable device. The camera can rotate in a self-adaptive mode, or the angle is controlled remotely by a supervisory person to obtain the optimal angle for evidence shooting. The microphones may also be adaptively adjusted or remotely adjusted by a supervisory person to obtain the best sound effects for forensic recording.
In one embodiment, the forensic of the criminal suspect's surroundings comprises:
carrying out evidence obtaining shooting on the surrounding environment of the criminal suspect;
and carrying out evidence obtaining and recording on the surrounding environment of the criminal suspect.
And step S14, starting a whistle function and sending out alarm notice to all public security points in a circular area taking the criminal suspect as a circle center and a preset alarm distance as a radius under the condition that the action characteristics deviate from the action rule.
In one embodiment, in the case that the action characteristic deviates from the action rule, activating a whistle function includes:
when the geographic position of the criminal suspect exceeds a specified activity range or the deviation of the geographic position of the criminal suspect from the activity range of the geographic position in the action rule exceeds a preset threshold value, judging that the geographic position deviates from the action rule;
the whistle function includes playing warnings of surrounding people and counseling criminal suspects.
For example, it is specified that a criminal suspect can only act in the western city of beijing city, and if the geographical location of the criminal suspect is found to exceed the administrative division of the western city of beijing city, the criminal suspect is determined to be illegal and should immediately whistle.
In one embodiment, the method for issuing an alarm notification to all public security points in a circular area with the preset alarm distance as the radius and the circle center of the criminal suspect comprises the following steps:
to the circle center of the criminal suspect and the direction angle plus or minus
The sector area with the radius of (5 + v) km as the direction angle sends the alarm condition report;
wherein v is the current moving speed of the criminal suspect, v max The maximum moving speed of the criminal suspect.
By the formula, the direction angle and the alarm notification radius are flexibly set, so that irrelevant public security points can be prevented from being influenced, and the workload of the public security points is reduced.

and S15, under the condition that the action characteristics deviate from the action rule, sending an interception instruction to all public transport facilities in a circular area with the circle center of the criminal suspect and the preset interception distance as the radius.
In particular, if a criminal suspect takes a public transportation means to escape, on the one hand, public safety may be endangered, and on the other hand, the criminal suspect may quickly get away from a monitored area and lose a tracking target. Therefore, the public transportation facility refuses to carry the criminal suspect by issuing the interception instruction to the public transportation facility. Even, the passage of the public transport means can be closed, and the criminal suspect can be controlled to continuously escape.
And S16, sending an alarm to an adjacent public security website under the condition that the public transport facilities find the criminal suspect.
