Fig. 1 is a schematic flowchart of a distance abnormality alarming method of a prison management system based on UWB positioning in an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a distance anomaly alarm method for a prison management system based on UWB positioning, where the method is applied to a positioning wearable device, the positioning wearable device is respectively connected to a positioning base station and a supervision platform, and the positioning wearable device may be a positioning bracelet, a foot ring, an arm ring, or another human body wearable device, and the method includes:
step 110: obtaining a first position of a first criminal person at a first time;
step 120: obtaining a second position of a second criminal person at said first time;
specifically, the distance abnormity warning method of the prison management system based on UWB positioning is applied to a positioning wearing device, and the positioning wearing device is respectively connected with a positioning base station and a supervision platform. The positioning wearing device adopts an ultra-wideband positioning technology and a GPS technology to establish a multifunctional personnel positioning system for recording the movement track of a wearing person in one day, and has a remote reading function and a positioning function. According to the pitch anomaly alarm method of the prison management system based on the UWB positioning, which is disclosed by the embodiment of the invention, prisoners in prisons are required to wear the positioning wearing device, the positioning base station is installed in a space in advance, the positioning wearing device emits UWB signals, the positioning base station obtains the positioning tags of the positioning wearing device after receiving the UWB signals and sends the positioning tags to the supervision platform, so that the personnel wearing the positioning wearing device can be tracked and positioned in real time, valuable real-time position information, condition early warning information and active warning information are provided for prison managers to further master the number and information of prisoners in each controlled area in prisons in real time, and the management level of the prisons is obviously improved. The method comprises the following steps: firstly, a first position of a first prisoner at a first time and a second position of a second prisoner at the first time are obtained, namely, whether the prisoners intentionally approach, get through messages or collude to break a prison or not is determined by obtaining different positions of different prisoners at the same time; the prisoner can also be determined whether any prisoner intentionally approaches or approaches the prisoner by obtaining different positions of the prisoner and the prisoner at the same time, so that the personal safety of the prisoner is prevented from being threatened.
Step 130: determining a first distance difference between the first location and the second location based on the first location and the second location;
step 140: judging whether the first distance difference is lower than a first preset threshold value or not;
step 150: and when the first distance difference is lower than the first preset threshold value, sending first alarm information to the supervision platform.
Specifically, according to the first position of the first prisoner at the first time and the second position of the second prisoner at the first time, a first distance difference between the first position and the second position is calculated, and then whether the first distance difference is lower than a first preset threshold is judged, wherein the first preset threshold is a distance threshold preset by the supervision platform for different prisoners at the same time, the numerical value of the first preset threshold is set according to regulations and requirements of prison management, whether different prisoners approach is judged according to the first preset threshold, namely when the first distance difference is lower than the first preset threshold, it is indicated that the first prisoner and the second prisoner approach too closely, a potential safety hazard exists, and then first alarm information is sent to the supervision platform, is used for reminding prison managers of finding abnormal conditions in time, taking precautionary measures as early as possible and not letting lucky molecules get hold of life.
Further, the method further comprises: obtaining a second time that said first criminal person is at said first location; obtaining a third time that said second criminal person is in said first position; determining a time difference between the second time and the third time according to the second time and the third time; judging whether the time difference is smaller than a second preset threshold value or not; and when the time difference is smaller than the second preset threshold value, sending second alarm information to the supervision platform.
Specifically, prisoners can freely move in a limited indoor and outdoor space, and according to the prison management regulations, the time interval between different prisoners arriving at the same position cannot be too short, so as to prevent the prisoners from transmitting information which is not beneficial to prisoner transformation by placing suspicious objects at the same position, such as the actions of crossing prisons, hurting the bodies of other people and even threatening the lives of other people, and therefore, by acquiring the second time of the first prisoner at the first position and the third time of the second prisoner at the first position, namely acquiring different time points of the different prisoners arriving at the same position, calculating the time difference between the second time and the third time, and then judging whether the time difference is smaller than a second preset threshold value, wherein, the second preset threshold is a time difference threshold of different prisoners at the same position preset by the supervision platform, the numerical value of the second preset threshold is set according to regulations and requirements of prison management, whether the time intervals of the different prisoners reaching the same position are too short is judged through the second preset threshold, when the time difference is smaller than the second preset threshold, the time intervals of the first prisoner and the second prisoner reaching the first position are too short, a potential safety hazard exists, and at the moment, a second alarm message is sent to the supervision platform to remind a prison manager to find abnormal conditions in time, precautionary measures are taken as early as possible, and serious consequences of prison crossing, prisoner fighting and even life threatening are avoided, so that the purpose of preventing prison is achieved.
Further, the method further comprises: obtaining a first area in which a first location of said first criminal person is located; obtaining a second area at which a second location of the second criminal person is located; judging whether the first area and the second area have an overlapping area; when a superposition area exists, judging whether the distance of the superposition area is larger than a third preset threshold value or not; and when the distance between the overlapped areas is larger than the third preset threshold value, sending third alarm information to the supervision platform.
Specifically, different types of criminals are located in different areas, for example, different criminals in a criminal case may be eschewed in different areas of a prison, and the monitoring platform may also set that the distance between the overlapping portions of two of the criminals cannot be too close, specifically, by obtaining a first area where a first position of the first criminal is located and a second area where a second position of the second criminal is located, and then determining whether there is an overlapping area between the first area and the second area, that is, by obtaining different areas where different criminals are located, determining whether there is an overlapping area between the different areas, and when there is an overlapping area between two different criminals, continuing to determine whether the distance between the overlapping areas is greater than a third preset threshold, wherein, the third preset threshold value is preset by the supervision platform to judge whether the distance between the overlapping areas of the areas where two prisoners are located meets the requirement, when the distance between the overlapping areas is larger than the third preset threshold value, the fact that the distance between the overlapping areas of the areas where the first prisoner and the second prisoner are located does not meet the requirement of the supervision platform is shown, namely, the areas where two different prisoners are located are too close to each other, third alarm information is sent to the supervision platform, and the third alarm information is used for reminding a prisoner manager that the two prisoners which are not too close to each other are approaching a server.
Further, the method further comprises: obtaining a third position of a third criminal person at said first time; determining a second distance difference between the first location and the third location; judging whether the second distance difference is lower than a fourth preset threshold value or not; and when the second distance difference is lower than a fourth preset threshold value, the third prisoner and the first prisoner are subjected to related grouping, and the third prisoner and the first prisoner are determined to belong to a first group.
Specifically, in prisons, prisoners or prison managers can group prisoners, so that the prisoners can participate in a series of labor reconstruction activities, supervise and urge each other, and the reconstruction purpose is achieved. Specifically, a third position of a third prisoner at the first time and a first position of a first prisoner at the first time are obtained, namely, positions of different prisoners at the same time are obtained, then a second distance difference between the first position and the third position is calculated, whether the second distance difference is lower than a fourth preset threshold is judged, the fourth preset threshold is a distance threshold of different prisoners at the same time and preset by a supervision platform, whether the distance between the third prisoner and the first prisoner at the first time is within a distance range of the same group of prisoners is judged by the fourth preset threshold, and when the second distance difference is lower than the fourth preset threshold, the distance difference between the third prisoner and the first prisoner is within a normal distance range of the same group of prisoners is shown, and thus, the third prisoner and the first prisoner are grouped in a related way, and then the third prisoner and the first prisoner are determined to belong to the same group by looking up the supervision platform. Furthermore, the technical effect of distinguishing the number and information of different groups of prisoners is achieved through real-time position tracking.
Further, said associatively grouping said third referring person with said first referring person, determining that said third referring person and said first referring person belong to a first group, comprises: obtaining first attribute information of said first criminal person; obtaining third attribute information of the third prisoner; judging whether the first prisoner and the third prisoner have a first incidence relation or not according to the first attribute information and the third attribute information; -when said first criminal person does not have a first associative relation with said third criminal person, -associatively grouping said third criminal person with said first criminal person.
Specifically, in the process of performing association grouping on different prisoners and determining which prisoners are in the same group, the specific grouping rule is as follows: first attribute information of the first person serving a criminal is obtained, wherein the first attribute information contains information such as sex, age, criminal service, starting service date and service duration of the first person serving a criminal, and third attribute information of the third person serving a criminal is obtained at the same time, and the third attribute information contains basic information such as sex, age, criminal service, starting service date and service duration of the third person serving a criminal; and then, judging whether the first prisoner and the third prisoner have a first association relationship according to the first attribute information and the third attribute information, for example, whether the first prisoner and the third prisoner are criminals in the same criminal case or not, or whether the first prisoner and the third prisoner are criminals of the same type, and when the first prisoner and the third prisoner do not have the first association relationship, performing association grouping on the third prisoner and the first prisoner, further identifying identity information of the prisoners in real time through the supervision platform, so that the prisoners of different types and different cases are distributed in the same group, the management difficulty of the prisoners is reduced, and the technical effect of improving the prison management level is achieved.
