Abstract
The utility model relates to a vehicle-mounted human index monitor which comprises an alcohol test module, a heart rate test module, an engine control module, a voice module and an indicating lamp circuit, wherein the alcohol test module and the heart rate test module are both connected with a microcontroller; the engine control module and the voice module are connected with and controlled by the microcontroller; the indicating lamp circuit is used for displaying the state of a driver and connected with the microcontroller; the alcohol test module comprises a sensor and a comparator circuit which is in signal connection with the sensor; and the heart rate test module comprises a heart rate sensor, a signal processing circuit and a signal amplifying circuit which are in signal connection sequentially. The vehicle-mounted human index monitor tests the body state of a driver in real time by adopting the alcohol test module and the heart rate test module; and when judging that the body state of the driver is inadequate for driving, the engine is closed after automatic voice alarming and prompting, thus ensuring the safe driving.
Description
Technical field
The utility model relates to the vehicle electronics product field, specifically is meant vehicle-mounted human body indicators monitor.
Background technology
Along with the progress of expanding economy and society, people's living standard improves constantly, and automobile is also more and more come into people's life.The recent statistics data display that China Association for Automobile Manufacturers announces, 09 year first half of the year, China's domestic automobile volume of production and marketing reached 599.08 ten thousand and 609.88 ten thousand respectively, increased by 15.22% and 17.69% on a year-on-year basis.The increase of automotive use amount has brought more problem simultaneously, for example, and traffic pressure, environmental pollution and security problems.Wherein many for safety problem human element influence, for example drive when intoxicated, fatigue is driven etc., therefore is necessary to take countrmeasure to ensure people's life security.
The utility model content
The problem that the utility model need solve provides a kind of condition situation of motorist that can detect in real time to guarantee the human body indicators monitor of traffic safety.
According to the above-mentioned problem that needs solution, the technical scheme that the utility model is taked is: a kind of vehicle-mounted human body indicators monitor is provided, comprise alcohol screen test module and heart rate test module, described alcohol screen test module all is connected with micro controller system with the heart rate test module, also comprises being connected engine control module and the voice module that is subjected to its control with micro controller system.
The utility model comprises also and is used to the indicator light circuit that shows whether the driver condition situation exceeds standard that this indicator light circuit is connected with micro controller system.
Described alcohol screen test module comprises sensor and and sensor signal bonded assembly comparator circuit.
Described heart rate test module comprises signal bonded assembly heart rate sensor, signal processing circuit, signal amplification circuit successively.
With respect to prior art, the beneficial effects of the utility model are: the utility model adopts alcohol screen test module and heart rate test module to detect driver's condition in real time, when judging that driver's condition is not suitable for driving, kill engine after the automatic speech alarming prompting, guarantee traffic safety.
Description of drawings
Fig. 1 is the utility model theory of constitution schematic block diagram.
The specific embodiment
Understanding for the ease of those skilled in the art is described in further detail the utility model below in conjunction with drawings and Examples:
As Fig. 1 is the utility model theory of constitution schematic block diagram.Vehicle-mounted human body indicators monitor described in the utility model comprises that micro controller system 10 reaches and micro controller system 10 bonded assembly alcohol screen test modules 11, heart rate test module 12, engine control module 13 and voice module 14, also comprises and micro controller system bonded assembly indicator light circuit 15.
During specific implementation, described alcohol screen test module comprises sensor and comparator circuit, comparator circuit one input end is imported a fixed voltage value, the other end connects the sensor signal mouth, alcoholic strength in the sensor vehicle environment changes input comparator circuit behind the voltage signal into, gives micro controller system by comparator output particular level signal.This module can adopt existing mature modules.
Described heart rate test module 12 can comprise heart rate sensor and signal processing circuit, signal amplification circuit.This module can adopt existing mature modules.
Described audio alert module adopts a speech chip IC2 to drive loud speaker by aerotron Q2 and realizes phonetic function.
Principle of work of the present utility model is: when the driver drives to strike sparks, can open each appliances power source in the car simultaneously, at this moment, the utility model gets electric work.Bright and the voice suggestion driver of its rear indicator light D2 that powers on detects condition.The driver can estimate sensor to alcohol and exhale, and utilizes heart rate test module testing heart rate.
The gaseous alcohol concentration of driver's exhalation is big if vehicle-mounted human body indicators monitor detects, and the voltage that then is converted to is big, and when the setting voltage value of voltage above another input end of comparator, then comparator output terminal output particular level signal is given micro controller system.The heart rate test module testing is exported to micro controller system to driver's heart rate situation simultaneously.If a nonconformity is arranged in two indexs, then Single-chip Controlling indicator lamp D4 is bright, by engine control module combustion cutoff priming supply, driving engine can not be started simultaneously, to guarantee safety.If two index is all qualified then Single-chip Controlling indicator lamp D3 is bright, prompting detects by can normally starting vehicle.
In addition when driving, the heart rate detection module detects driver's heart rate situation in real time and then judges whether the driver is in fatigue driving state, indicator lamp D5 is bright if judgement is in fatigue driving state and the audio alert prompting, after postponing a period of time, driver's parking that also do not kill engine, then the combustion cutoff power supply cuts off the power supply and stops working, and guarantees safety.
Above embodiment only is the preferable implementation of the utility model, can not limit the utility model with this, is not breaking away under the utility model design prerequisite, and its any being equal to of doing is replaced and subtle change all belongs to protection domain of the present utility model.
