Kindergarten school bus anti-omission device based on RFID

Abstract

The invention provides a kindergarten school bus anti-omission device based on RFID. The kindergarten school bus anti-omission device includes an in-car detection subsystem and a remote monitoring subsystem connected with the in-car detection subsystem. According to the kindergarten school bus anti-omission device based on the RFID, whether children miss in a school bus and the number of the missing children can be accurately detected, school bus shut down and whether the bus door is closed can be accurately detected, the information is transmitted to the remote monitoring subsystem, management personnel can see the situation of the children in the school bus at any time through a remote monitoring center, when children miss in the car, the remote control center sends out sound and light to alarm and displays bus information and names, classed and other information of the missing children in the bus, the safety hidden danger caused by the children left in the school bus is effectivelyavoided, safety is greatly improved, and the kindergarten school bus anti-omission device based on the RFID has the advantages of high reliability, being convenient to use, remote monitoring, and remote query.

Description

technical field [0001] The invention belongs to the technical field of automotive electronic security, and in particular relates to an RFID-based kindergarten school bus anti-missing device. Background technique [0002] In recent years, tragedies of missing children on the kindergarten school bus have occurred from time to time, and the kindergarten school bus has brought a lot of convenience to the parents. However, it has brought safety problems. Because the children are young and lack Self-protection awareness, once it is missed in the car, if it cannot be discovered in time, it will bring irreparable and terrible consequences. At present, kindergarten school buses lack necessary detection devices, and it is difficult to guarantee that similar tragedies will not happen again only by human detection. [0003] Since such tragedies happen every year, some people also conduct research on this. The usual method is: when it is detected that the car is turned off and the door ...

AI Technical Summary

Problems solved by technology

[0004] 1. Use the human pyroelectric infrared sensor to detect whether there is a child in the car, but the human pyroelectric will be interfered by the surrounding human body, animals, heat sources, and electromagnetic waves. It is difficult to accurately detect when the child is in a static state such as sleep. The reliability of the method is not high, there are false positives and negative negatives, and it is difficult to meet the practical requirements;

[0005] 2. Detect whether there is a child in the car through infrared transmission and reception. When the child is in the car, it will block the infrared light and trigger an alarm. However, if there are goods or objects in the car that block the infrared rays and cause false alarms, or the interference of infrared rays outside the car, etc., the same It will cause false positives or false negatives, and the reliability is not high;

[0006] 3. Use the pressure sensor to detect whether there is a child in the car, but: there is the possibility of false alarms caused by objects placed in the car, or the child may stand up or not sit within the effective detection range of the pressure sensor, causing false alarms. low level problem
