Embodiment

[0042] figure 1 It is a structural schematic diagram of an early warning system for identifying children accidentally locking the car in the present invention.

[0043] In this example, if figure 1 As shown, the present invention is an early warning system for identifying children accidentally locking the car, including: A gravity sensing cushion and B early warning host;

[0044] Among them, A gravity sensing cushion includes: A1 sensor, A2 battery, A3 microcontroller, A4 Bluetooth module;

[0045]A1 sensor is composed of a thin-film resistive pressure sensor and a detection circuit; the contacts of the thin-film resistive pressure sensor are evenly distributed on the stress-bearing surface of the cushion. When the cushion is subjected to external pressure, the thin-film contact deforms, resulting in a corresponding change in resistance value ; The detection circuit is preset with the resistance value range corresponding to the weight range of all ordinary children. Accordi...

Abstract

The invention discloses an early warning system for recognizing whether a child is mistakenly locked in an automobile or not. The early warning system is used for preventing the situation that the child is mistakenly locked in the automobile and an accident occurs. The system comprises a gravity sensing cushion and a main early warning machine. The gravity sensing cushion is placed on a child seat or other seats and internally provided with a gravity sensor, and whether the child sits on the cushion or not is judged by sensing the gravity borne by the cushion. The main early warning machine is installed in the proper position below an automobile instrument desk and connected with signal lines of an automobile central lock, a side door switch, a start switch, a double-flash switch and a horn switch. The state of the automobile start switch, the state of the side door switch and the state of the central lock are monitored through the main early warning machine in real time, a signal indicating whether the child is in the automobile or not is obtained from the gravity sensing cushion through a Bluetooth module, and according to the signal and the states, a logical judgment is made, and an early warning is given according to the condition that the child is mistakenly locked in the automobile.

Description

technical field [0001] The invention belongs to the technical field of safety early warning, and more specifically relates to an early warning system for identifying children who accidentally lock the car. Background technique [0002] With the increase in the number of cars and the popularization of family cars, there are more and more accidents related to the use of cars. In recent years, there have been reports of careless parents leaving infants and young children in cars all over the world, resulting in accidental deaths of infants and young children. Infants and young children are locked in the car alone, and accidents are prone to occur because they do not have the awareness and ability of self-protection. Especially in summer, under the airtight exposure, the instantaneous temperature inside the car can reach more than 60 degrees. Because children are not fully developed, their body temperature rises and body water loses faster than adults, and their respiratory sy...
