Jail locating node system based on wireless sensor network

Abstract

The invention discloses a jail locating node system based on a wireless sensor network. A wireless gateway is in wireless connection with locating nodes. A plurality of wireless routers and the locating nodes are adopted, and the wireless routers are in wireless connection with the locating nodes. Each locating node comprises an MCU processor, a storage device, a communication module, an acceleration speed sensor, a gravity sensor, a battery management unit, a loudspeaker, a microphone, a liquid crystal touch display screen and a camera, the storage devices, the communication modules, the acceleration speed sensors, the gravity sensors, the battery management units, the loudspeakers, the microphones, the liquid crystal touch display screens and the cameras are connected with the MCU processors, and the battery management units are connected with rechargeable batteries. According to the jail locating node system, the network locating and monitoring nodes based on the ZigBee communication technology are adopted, the advantages of being low in cost, low in power consumption, high in safety, long in work distance, rich in function and the like are achieved, and the good effect is obtained in jail monitoring activities.

Description

technical field [0001] The invention relates to the technical field of prison wireless positioning and monitoring, in particular to a prison positioning node system based on a wireless sensor network. Background technique [0002] With the gradual improvement of the prison management system and the continuous updating of monitoring facilities, the ability of the detention center to prevent and control various security incidents has been greatly enhanced. However, as the types of crimes and the composition of detainees become more and more complex, detainees will become more vengeful, cruel and cunning. If they are not careful, they will take reckless risks, wait for opportunities to take hostages, escape, commit suicide, homicide, and gang collusion. It has an extremely adverse impact on personal safety and the stable management of detention centers. At present, the methods of electronic access control, camera monitoring, and alarm systems adopted by criminal supervision pl...

However, as the types of crimes and the composition of detainees become more and more complex, detainees will become more vengeful, cruel and cunning. If they are not careful, they will take reckless risks, wait for opportunities to take hostages, escape, commit suicide, homicide, and gang collusion. extremely adverse impact on personal safety and stable management of detention centers

At present, the methods of electronic access control, camera monitoring, and alarm systems adopted by criminal supervision places in China are not effective enough in complex on-site situations. The limited police force cannot monitor the situation of each prisoner in real time through the lens, and the supervisors cannot grasp the situation of each prisoner in real time. The number and detailed information of the detainees in the control area, resulting in the emergence of some security risks
