A method to reduce the false alarm rate of cross-border judicial community correction management system
A management system and community correction technology, applied in the fields of electronics and communications, can solve problems such as waste of manpower and material resources, misjudgment of spatial location, affecting the normal social life of correction subjects, etc., to reduce the consumption of manpower and material resources, reduce the rate of false alarms, avoid The effect of not alarming when crossing the boundary

Embodiment 1
[0027] Such as Figure 1 to Figure 3 A method for reducing the false alarm rate of crossing the boundary of the judicial community correction management system is shown, including the following steps:
[0028] First, establish a directional subdivision model for the area to which the corrected individual with a high false positive rate belongs, and the specific steps are as follows:
[0029] Judging the active area to which the corrected object belongs, using software to reconstruct or collect the existing map graphics including at least the boundary line information of the area from the network or control platform database, within the scope of the area boundary line on the map graphics Select a central origin at the position of the central origin, divide the map graphics into eight directions through a plurality of rays or line segments starting from the central origin, and establish a directional division model including eight equal unit divisions, such as figure 2 shown. ...
Embodiment 2
[0036] Its implementation steps are the same as in Embodiment 1, assuming that the false alarm occurrence point or the reasonable activity range of the corrected object near the boundary crosses the fourth and fifth unit divisions, such as Figure 4 As shown, the expanded boundary line is as follows Figure 5 shown.
Embodiment 3
[0038] A method for reducing the cross-border false alarm rate of the judicial community correction management system, comprising the following steps:
[0039] Judging the active area where the corrected object whose cross-border false alarm rate is higher than the set standard belongs to, construct or collect a map graphic that includes at least the boundary line information of the area, and select a center origin within the area boundary line on the map graphic ;
[0040] According to the location data collected by the positioning equipment of the management system or the information collected by the manager, mark the occurrence point of the false alarm in the map graphic or circle the reasonable range of activities where the corrected object generates a false alarm near the boundary;
[0041] Judging and selecting the two false alarm occurrence points with the largest angle with the center origin connection line, or finding the two ends with the largest angle with the cente...
