Abstract
The utility model discloses a displaying and early-warning device of a children bicycle, and relates to a speed early-warning device of a bicycle, in particular to a speed displaying and early-warning device of the children bicycle. A single chip microcomputer is taken as a main control chip of a CPU (central processing unit), the CPU is connected with a speed configuration unit to obtain preset speed data, a speed detection unit is connected with a speed measurement sensor to obtain real-time speed data, a signal is outputted to a voice prompting circuit and an LED (light emitting diode) display after the preset speed data and the real-time speed data are subjected to comparison process, and the CPU provides a prompting signal to a guardian receiver through a wireless transmission circuit. The displaying and early-warning device of the children bicycle, disclosed by the utility model, has the advantages that the displaying and early-warning device is designed according to physiologic and psychological characteristics of children and a caution speed can be preset according to different situations of the children; the voice prompting circuit is divided into three grades, namely a tender prompt grade, a normal early-warn grade and a serious order grade; and meanwhile, the displaying and early-warning device can keep communication with a guardian through the wireless transmission circuit at any time so as to ensure the personal safety of the children to the maximum extent. The displaying and early-warning device of the children bicycle has the characteristics of simple structure, reliable performance, safety and practicability, and low cost.
Description
Technical field
The utility model relates to the bicycle speed prior-warning device, and particularly a kind of child's bicycle speed of a motor vehicle shows and prior-warning device.
Background technology
Child's bicycle is one of toy of doting on of child, and some child's bicycle speed is close to adult bicycle.Yet because the Most of children concept that easily has an accident by bike of hypervelocity not, the guardian also can not look over one's shoulder child by bike all the time, and this just means and has certain potential safety hazard.The problem that has easily had an accident by bike in order to have solved children's hypervelocity must adopt according to infantile psychology and tutorial reality the vehicle speed prewarning device of specific function, and child protection to greatest extent reaches the purpose of healthy amusement.
Summary of the invention
To be that design is a kind of also remind tutorial prior-warning device when self sending caution when child's bicycle exceeds the speed limit to the purpose of this utility model.
The technical solution of the utility model is: this device with a singlechip chip as the CPU main control chip, CPU is connected to the speed setting unit and obtains the preset speed data, the Negotiation speed detecting unit is connected to tachogenerator and obtains the real-time speed data, Data Comparison is processed rear output signal to voice warning circuit and light-emitting diode display, and CPU provides alerting signal by radio transmitter to guardian's receptor simultaneously.
The beneficial effects of the utility model: this device designs for children's physiology and psychological characteristics, can be according to children's different situations predetermined warning speed, and voice warning circuit is divided into tenderness, normal and severe class.Keep linking up with the guardian at any time by radio transmitter simultaneously, guarantee to greatest extent children's personal safety.That this device has is simple in structure, dependable performance, safe and practical, cheap characteristics.
Description of drawings
Accompanying drawing 1 is the utility model circuit block diagram.
The specific embodiment
As the CPU main control chip, CPU is connected to the speed setting unit and obtains the preset speed data this device with an AT89C2051 singlechip chip, and the speed setting unit cooperates input preset speed numerical value by button with light-emitting diode display.CPU Negotiation speed detecting unit is connected to tachogenerator and obtains the real-time speed data, and tachogenerator is comprised of a dry-reed tube and the some magnet that are distributed on the wheel circumference.CPU compares the rear output signal of processing to voice warning circuit and light-emitting diode display with preset speed numerical value and real-time speed data.Voice warning circuit prestores suggestion voice, and suggestion voice is divided into three class: when real-time speed sends gentle suggestion voice during near preset speed; When reaching preset speed, sends real-time speed normal early warning voice; Send severe order voice when real-time speed reaches preset speed and surpasses preset time, CPU provides alerting signal by radio transmitter to guardian's receptor simultaneously.
This device designs for children's physiology and psychological characteristics, guarantees to greatest extent children's personal safety.That this device has is simple in structure, dependable performance, safe and practical, cheap characteristics.
Claims (2)
1. a child's bicycle shows prior-warning device, it is characterized in that: this device with a singlechip chip as the CPU main control chip, CPU is connected to the speed setting unit and obtains the preset speed data, the Negotiation speed detecting unit is connected to tachogenerator and obtains the real-time speed data, Data Comparison is processed rear output signal to voice warning circuit and light-emitting diode display, and CPU provides alerting signal by radio transmitter to guardian's receptor simultaneously.
2. a kind of child's bicycle according to claim 1 shows prior-warning device, and it is characterized in that: the suggestion voice that voice warning circuit prestores is divided into three class.
