Definitions

  • SUBSTANCE invention relates to a monitoring system and a portable device designed to detect and track the movement of offenders in a restraining order program established by a court in order to prevent offenders from violating restrictions and/or approaching a victim.
  • the system can be used both in the case of "house arrest” and in other areas of economic activity that require the location of controlled objects.
  • Known automated tracking system which describes a method and device for tracking the location of assets and people.
  • location information is periodically provided to a central monitoring station.
  • the central monitoring station uses the software to analyze the information received remotely and to determine the appropriate actions to be taken with respect to this information.
  • the central monitoring station should periodically notify authorized users of the location and status of the monitored person or asset.
  • the central monitoring station works without the need for the object to analyze the information received remotely.
  • the use of aperiodic transmission of information to the central monitoring station and the use of software at the central monitoring station allows the present invention to efficiently process information received from a large number of remote devices.
  • a portable tracking device which includes a connector for attaching the device to the body of a tracked object, a location module used to determine the location of a portable tracking device, a short-range wireless communication module that communicates with the base monitor and a wireless communication module long range, which in turn communicates with the main system monitoring; a control module that monitors the operation of the portable tracking device.
  • the disadvantage of this system is that the base monitoring device is stationary, located inside the room for which the GPS positioning coordinates are set, and situations often arise when the base monitor does not “see” the GPS satellites. Another disadvantage is the increased consumption of energy to maintain constant communication with these satellites. Another drawback is that the system only tracks the object that should be tracked, while not tracking the victim.
  • a warning system about the presence of the offender which includes: a tracking device securely attached to the arm or leg of the offender, which contains a GPS receiver and a wireless modem, a radio frequency transceiver designed to transmit radio frequency signals at certain intervals. And the victim has a transceiver that receives signals from the offender's tracking device when he is in close proximity to the victim. The victim's device, in response to the RF signals received from the tracking device, generates an alert signal to alert the victim to the presence of the perpetrator, and automatically transmits the RF signal to the perpetrator's tracking device, which, upon receiving this RF signal, generates an alarm alerting the perpetrator that he is too close to the victim.
  • the criminal tracking device sends a signal to the monitoring station, which contains both information about the identifier (ID) of the offender and the identifier (ID) of the victim's device, and at the same time location information with GPS positioning coordinates.
  • the disadvantage of this system is that the monitoring of all nodes of the system is based only on their uninterrupted interaction with the GPS satellites and, as a result, excessive power consumption of power sources, which can lead to incorrect determination of the location of the observed persons and reduce the autonomy of their use.
  • the technical problem solved by the invention is to implement an object monitoring system that would allow to increase the period of use of the power sources of the system units without recharging, to improve the accuracy of transmitted and received data from system blocks, increase the number of monitoring objects, creating a reliable bracelet device, protected from any interference.
  • the personal monitoring system in accordance with the invention eliminates the above-mentioned disadvantages by the fact that it contains: a tracking bracelet device securely attached to the leg or arm of the observed object, containing: a rechargeable battery, a microcontroller with a unique ID and an RF transceiver designed to transmit unique coded low-power short-range RF signals at programmed time intervals, antenna, motion sensor module, proximity sensor, bracelet integrity monitoring, LED indicator; main portable device placed permanently inside the controlled person's premises or carried by him when he leaves the premises, and containing: a battery for supplying power to the specified main device, a charge or discharge controller, a microcontroller with a unique ID, a multi-standard GNSS module with a built-in antenna, RF transceiver with antenna, GSM/LTE communication module with antenna, memory chip, LED indicator and sound source, motion sensor module, integrity control of the main device; portable warning device of a third party, located permanently inside the premises of a third party or carried when it leaves the premises and containing:

  • the advantages of the present invention are due to the separated functions of the main unit and the bracelet device for tracking the offender, which achieves compactness and long-term autonomy of the latter, since the main consumers of energy are GPS navigation and server communication devices.
  • the system can track in addition to the offender and a group of up to 5 victims (third parties).
  • the system allows you to operate bracelets autonomously for 1 year, and the main unit in autonomous mode - up to 4 days.

  • the system consists of the radio bracelet 2 itself, fixed on the observed offender (foot, arm), the transceiver unit (base) 3, installed in the visibility zone of the radio bracelet 2 (for example, in an apartment), the server 4 of the monitoring center and the control room software .
  • Base 3 In stationary mode, base 3 must be connected to a power source via a charger adapter, while it has a built-in battery for autonomous operation up to - 3-4 days. Data transmission from the base 3 to the central server 4 is carried out via GSM/WCDMA/LTE cellular channels. All information from all monitoring objects is transmitted to the central server 4 and stored for further analysis.

  • Base 3 can be programmed to track one radio bracelet 2 and/or up to five radio bracelets or for multiple ID identification, which may be required in the case of monitoring a limited group of bracelet wearers at the same time.
  • Another use case is programming the base for the IDs of other real bracelets (as victims), when it is necessary to limit the meeting of bracelet wearers among themselves (up to 5 objects).
  • the radio bracelets register opposite to each other, as in the case of the victims, except that the SMS signal and the call are made to the service operator in the control room.
  • the main operating situations of the system are as follows:
  • base 3 Normal behavior of the owner of the bracelet - base 3 receives signals from his bracelet 2, receives signals from GPS satellites, the battery charge of base 3 and the network signal level are normal, base 3 does not “see” the signals of key fobs 5 (victims or other objects registered in it) approximately within a radius of 50 m ... 100 m.
  • any of the above parameters is violated - the operator receives an alarm signal (SMS and, if necessary, a call with a voice message). Intentional minor deviations from the norm are usually monitored.
  • Base 3 in this case emits appropriate beeps, with which the wearer of the bracelet can correct the situation.
  • the base 3 upon detecting the radio signal emitted by the victim's key fob 5, the base 3 immediately turns on the sound signal, transmits this fact to the server 4, sends an SMS and calls the victim's mobile phone, warning him of the danger.
