Abstract
The utility model is, a kind of battery-driven car speed measurement alarm device, comprises Hall element, signal input processing circuit, single chip processing module, liquid crystal display, phonetic warning device, buzzing warning device speed limit module.Hall element connection signal input processing circuit, signal input processing circuit connects single chip processing module, and single chip processing module connects liquid crystal display, phonetic warning device, buzzing warning device and speed limit module.The utility model can carry out measurement to the rotating speed of Electricmotor car wheel and obtain its moving velocity, realizes early warning and warning, thus improves its driving safety coefficient.
Description
Technical field
The utility model relates to battery-driven car security fields, particularly relates to a kind of battery-driven car speed measurement alarm device.
Background technology
Along with the owning amount of personal car constantly increases, the road in city becomes day by day crowded.And the impact of battery-driven car substantially not by city traffic congestion is current.Therefore, as in-plant main traffic instrument battery-driven car substantially each family have one at least.Huge battery-driven car owning amount inevitably causes battery-driven car and other vehicles or pedestrian collision, even causes personal injury.The battery-driven car traffic accident caused due to hypervelocity occurs again and again.Design a kind of battery-driven car speed measurement alarm device, by the principle of Hall effect, its speed travelled is obtained to the rotating speed measurement of Electricmotor car wheel, realizes the velocity measurement of battery-driven car, early warning and warning.
Summary of the invention
The purpose of this utility model is intended to the difficult problem solved, and provides a kind of battery-driven car speed measurement alarm device.
The utility model for achieving the above object, designs a kind of battery-driven car speed measurement alarm device, comprises speed limit module, sensor, treatment circuit, processing module, prior-warning device, read out instrument and warning device.
Described sensor dimension Hall element, the convert information that Hall element will pass through the presence or absence magnetic field detected via signal processing circuit is impulse singla;
Described treatment circuit is signal input processing circuit;
Described processing module is single chip processing module;
Described read out instrument is liquid crystal display, can be LED and LCD liquid crystal display screen, in order to the value of display display normal speed; Display current speed value is also reminded by hypervelocity; Show the velocity amplitude of current hypervelocity and remind hypervelocity; When stopping operating, not showing its speed, representing and halting; When wheel restarts, the speed of display is zero, represents and has restarted device.
Described prior-warning device is voice buzzing prior-warning device;
Described warning device is buzzing warning device.
Hall element connection signal input processing circuit, signal input processing circuit connects single chip processing module, and single chip processing module connects liquid crystal display, phonetic warning device, buzzing warning device and speed limit module.
The beneficial effects of the utility model are: the utility model can carry out measurement to the rotating speed of Electricmotor car wheel and obtain its moving velocity, realizes early warning and warning, thus improves its driving safety coefficient.
Accompanying drawing explanation
Fig. 1 is the structural representation that outer pod apertures of the present utility model tears valve self-closing device open;
Be described in detail with reference to accompanying drawing below with reference to embodiment of the present utility model.
Detailed description of the invention
The utility model designs a kind of battery-driven car speed measurement alarm device, comprises Hall element, signal input processing circuit, single chip processing module, liquid crystal display, phonetic warning device, buzzing warning device speed limit module.Hall element connection signal input processing circuit, signal input processing circuit connects single chip processing module, and single chip processing module connects liquid crystal display, phonetic warning device, buzzing warning device and speed limit module.
Be 20km/h according to the maximum speed of the requirement battery-driven car in relevant departments, when speed reaches certain value between 18km/h to 19.9km/h, Micro Controller Unit (MCU) driving phonetic warning module and on a liquid crystal display display be about to hypervelocity; When speed is more than 20km/h, Micro Controller Unit (MCU) driving buzzing alarm module and speed limit module, and point out over the display and exceed the speed limit.Only current velocity amplitude is shown over the display during usual speed.
