Detecting and warning device for school bus

Abstract

The invention relates to a detecting and warning device for a school bus. The detecting and warning device comprises a power module, a single chip microcomputer (SCM) control module, a detecting module and a warning module, wherein the power module is composed of a main power supply circuit supplied by an automobile power supply and an auxiliary power supply circuit connected with the main power supply circuit in parallel; the SCM control module is used for receiving data information acquired and detected by the detecting module and sending the data to the warning module after analysis and processing; the detecting module is composed of a sound detecting module and a microwave detecting module and used for acquiring and detecting data information about infrared rays in human bodies and sound respectively; and the warning module comprises an automatic bus door opening module, a sound reminding module and a global system for mobile communications (GSM) short message warning module and is used for executing the data information sent by the SCM control module. The detecting and warning device for the school bus overcomes the shortcomings such as weak self-rescue awareness of children,carelessness of people in charge and the like, and can detect children left in automobiles and inform drivers and other related people timely, therefore accidents of smothered children left in automobiles are prevented.

Description

technical field [0001] The invention belongs to the technical field of electronic detection, and in particular relates to a detection and alarm device for children on a school bus, which is installed in the vehicle as auxiliary equipment. Background technique [0002] On July 31, 2011, a tragedy occurred in a kindergarten in Xi'an City. A two-year-old girl was forgotten in the school bus that picked up the child and died. The death certificate issued by the hospital stated that the cause of death was "suffocation". The current children's school bus lacks the necessary detection and alarm devices, which makes the tragedy of children being forgotten in the car and eventually suffocated to death again and again; [0003] The current similar products also have their defects. First of all, in terms of detection, they mainly collect changes in environmental factors such as light, air, and temperature to judge whether there are children stranded. We know that children’s activities ...

Problems solved by technology

The current children's school bus lacks the necessary detection and alarm devices, which makes the tragedy of children being forgotten in the car and eventually suffocated to death again and again;

[0003] The current similar products also have their shortcomings. First of all, in terms of detection, they mainly collect changes in environmental factors such as light, air, and temperature to judge whether there are children stranded. We know that children’s activities cause relatively little environmental changes. Therefore, the detection effect must be unsatisfactory.
