Abstract
The utility model relates to an anti-sleeping device for a vehicle, which belongs to the field of ensuring safe driving systems of automobiles, and is characterized in that when an infrared receiver receives an infrared ray emitted from an in infrared emitter, a relay gating module can not enable a relay to be powered on, so that the relay can not actuate a switch controlled by the relay, and an electric horn sound production module can not work; and when the infrared receiver receives another infrared ray emitted by the infrared emitter, the relay gating module can power on the relay, so that the relay actuates the switch controlled by the relay, and the electric horn sound production module works and makes a sound.
Description
Technical field
The utility model relates to assurance vehicle safety travel system field, particularly a kind of automobile-used Drowse-proof device.
Background technology
Nowadays because the traffic hazard that causes owing to driver's doze in the vehicle traveling process is of common occurrence, find that when also having other people in the car driver's drowsiness can give the driver and remind, if but have only in the car when other people do not find that the driver is sleepy yet in man-hour of driver or the car, just may cause traffic hazard.
Automobile Drowse-proof device of today has plenty of the change-detection driver who bearing circle is held power according to the driver and whether is in doze state, but the variation that the driver holds power to bearing circle might not be because driver's drowsiness causes, and itself just be difficult to guarantee to hold to try hard to keep to hold a fixed value when driving, this just causes the out of true of this device work; Whether Drowse-proof device is in the vehicle ' process in the car that has, and can constantly ask a question, occur unusually according to the speed of answering a question, perhaps irrelevant, judge whether the driver is in doze state, the problem of so continuous proposition can allow the driver be weary of, even diverts attention.Above-described problem has to be solved, and this just needs a kind of new automobile-used Drowse-proof device, and the driver is reminded.
Summary of the invention
The purpose of this utility model is to address the above problem, and provides and award the device that assurance automobile that the driver reminds can safety traffic in a kind of vehicle traveling process when the driver dozes off.Be achieved through the following technical solutions:
A kind of automobile-used Drowse-proof device of the utility model, comprise accumulator, the electric horn sound-producing device, relay, infrared receiver, infrared transmitter, hand switch, relay gating module, relay control switch, resistance 1, described infrared transmitter is used for launching infrared signal, described infrared receiver is used for the infrared signal of receiving infrared-ray transmitter emission, the internal resistance of infrared receiver tube reduces in it when receiving infrared signal, and this moment, transistor base was the switch that low level relay gating module can not make the control of relay attracting electric relay; The internal resistance of its infrared receiver tube is bigger when not receiving infrared signal, and this moment, relay gating module made the switch of relay excitation attracting electric relay control.
Described infrared transmitter is installed on the interior ceiling of car, infrared receiver is installed in the driver's chair front, driver's head can not block the infrared signal of infrared transmitter emission when driver's state of mind is reasonable, and infrared receiver can receive infrared signal; Driver's head turns forward when the driver is sleepy, thereby blocks the infrared signal that infrared transmitter is launched, and this moment, infrared receiver did not receive the infrared signal that infrared transmitter is dispatched a car.Described relay gating module is made up of 10 resistance 2 and 11 triodes.
Described electric horn sound-producing device is that its prompting driver that sounds of switch closure of relay control when the driver is in doze state attentively drives.Described accumulator is to provide power supply for automobile-used Drowse-proof device.Described hand switch is for when driver's state of mind is relatively good, and the driver can close this device the saving power consumption.
Advantage of the present utility model:
1, the distance between infrared transmitter and the infrared receiver can be regulated, and adapts to different vehicles.
2, the infrared receiver of Cai Yonging can be distinguished the infrared signal that other objects that have temperature are launched in infrared signal that infrared transmitter sends or human body or the car, makes this device ratio of precision higher.
3, this apparatus structure is simple, be installed in take up room in the car little.
Description of drawings
Fig. 1 is the electrical block diagram of a kind of automobile-used Drowse-proof device of the utility model.
Embodiment
The 1-accumulator; 2-electric horn sound-producing device; The 3-relay; The 4-infrared receiver; The 5-infrared transmitter; The 6-hand switch; 7-relay gating module; The 8-relay control switch; 9-resistance 1; 10-resistance 2; The 11-triode.
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of automobile-used Drowse-proof device of the utility model comprises accumulator 1, electric horn sound-producing device 2, relay 3, infrared receiver 4, infrared transmitter 5, hand switch 6, relay gating module 7, relay control switch 8 etc.; The internal resistance of infrared receiver tube reduces in 4 when infrared ray receiver 4 receives the infrared signal of infrared transmitter 5 emission, and this moment, transistor base was that low level relay gating module 7 switch 8 electric horn sound-producing devices 2 that relay 3 attracting electric relays are controlled are inoperative; The internal resistance of its infrared receiver tube is not bigger when receiving infrared signal, this moment, transistor base was a high level, relay gating module 7 makes the switch 8 of relay 3 excitation attracting electric relays control, electric horn generating means 2 place circuit pathways, thus electric horn is sounded and is reminded to the driver.When driver's the state of mind is relatively good, can disconnect hand switch 6, save electric weight.
Claims (1)
1. automobile-used Drowse-proof device, comprise accumulator, electric horn sound-producing device, relay, infrared receiver, infrared transmitter, hand switch, relay gating module, relay control switch, it is characterized in that: described infrared receiver links to each other with relay gating module; Whether described relay gating module controls relay place circuit path; Described relay gating module is made up of resistance and triode; Described relay control switch links to each other with the electric horn sound-producing device.
