Children road safety device based on signal active identification and control method

Abstract

The invention discloses a child road safety device based on signal active identification and a control method. The child road safety device comprises a size-adjustable cap, an electronic control device is arranged at the top end of the cap and provided with a circular shell, and a signal transmitter and a warning lamp set are arranged on the periphery of the shell; the top of the shell is provided with a state indicating lamp, a charging interface and a photoresistor, and the shell is internally provided with a rechargeable battery, a charging circuit, a power supply circuit, a processor, and a signal emission circuit, a vibration detection module, a voltage division circuit and a light sensation circuit which are connected with the processor; the processor is used for realizing the control method and the method comprises the following steps: the vibration detection module outputs a vibration signal, and the processor enters a working state; battery voltage detection is conducted; the signal transmitter transmits a signal which can be identified by automobile ranging radar, and the warning lamp set flickers under the condition of low illumination; and within the duration of the time threshold T2, the vibration detection module does not output a vibration signal, and the processor enters a dormant state.

Description

technical field [0001] The invention relates to a children's road safety device and a control method based on signal active identification, and belongs to the technical field of intelligent wearable devices. Background technique [0002] Reports of children being maimed and killed by being run over by vehicles are common, which makes people feel sad. There are two main reasons for such a tragedy: first, the driver failed to effectively observe the situation around the vehicle, and the vehicle often has a visual blind spot, and the vehicle may be crushed when it starts, turns or reverses; Secondly, children are small, and they are less likely to be noticed after squatting down. Even if the vehicle has a radar system, the reflected signal will be weak or even missed, which will bury hidden dangers for children's safety. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and propose a children’s road safety device and cont...
