A method, system and device for monitoring and early warning of activity tracks of community correction objects

Abstract

The invention discloses a method, system and device for supervising and early warning of the activity trajectory of a community correction object. By collecting relevant information of the community correction object, multiple preset activity trajectories are formed, and then the actual activity trajectory of the community correction object is obtained through the Beidou positioning system. According to the similarity between the preset activity trajectory and the actual activity trajectory; traverse the location parameters and corresponding time length parameters in the actual activity trajectory of the community correction object that coincides with the bus station, railway station, airport, high-speed entrance, etc., and calculate the specific site calibration coefficient ; Obtain the virtual trajectory line by calculating the change trend of the actual activity trajectory, calculate the distance between the end point of the actual activity trajectory and the intersection point of the virtual trajectory line and the safety fence, and determine whether it is abnormal by setting the corresponding threshold. The invention also discloses a system and a device for realizing the method. The invention can predict in advance whether the activity trajectory of the community correction object is abnormal, and the calculation accuracy is high and the calculation is simple.

Description

Technical field [0001] The present invention relates to the field of intelligent monitoring, and specific relates to community correction target active trajectory prevention methods, systems and devices. Background technique [0002] In my country, community correction refers to non-supervision criminal implementation activities implemented by the four criminal acts of criminal acts that have been sentenced to control, probation, probation, rulers, and temporarily carry out foreign criminal activities, according to the crime of community correction objects. The activities of the community correction object are different. According to Article 26 of the Community Correction Law, Article 26 of the "Measures for Community Correction", community correction objects shall not leave the living market without approval. county. Any behavior that has not been approved to leave specific ranges is illegal. [0003] With the promulgation of community correction, the supervision of the strength...
