Abstract
The utility model provides a traffic blind area reminding device, which comprises a transmitter, an infrared sensor, a receiver, an amplifying circuit and an alarm. The traffic blind area reminding device has the following technical advantages that 1, the traffic blind area reminding device is simple in structure and low in cost, 2, the device senses moving objects through infrared rays and is high in sensitivity, and 3, the device can sense the moving objects within a range of tens of meters and rapidly feed back signals to a driver within a second, and work distance of the traffic blind area reminding device is much higher than that of an automobile radar, thereby greatly increasing traffic safety.
Description
Technical field
The utility model relates to a kind of sensor device, specifically, relates to a kind of traffic blind area reminding device that utilizes sensor.
Background technology
Traffic blind area refers on the run, because the influence of situations such as vehicle, landform, buildings and light, driver or pedestrian's sight line is subjected to restriction to a certain degree, and some traffic zone does not observe mutually, and this has just formed traffic blind area.The burst dangerous situation of often hiding in these blind areas is easily sent out traffic hazard in the intertwined point or during conflict point.Present traffic blind area mainly comprises following four kinds: 1, the blind area of self driving: owing to the vehicle structure reason, be sitting in interior some the sight line blind areas that always exist of pilothouse.As place that vehicle top and the bottom and left and right sides exterior mirror do not observe, these blind areas can produce potential safety hazard during at vehicle start, reversing, piggybacking, doubling and by the highway section that the crowd is dense.2, other vehicles blind area of causing: near vehicle that the vehicle that park in the roadside travels can giving and pedestrian cause the sight line blind area.When pedestrian or cyclist are crossed road from the vehicle of parking is other, cannot see the vehicle of sailing, and the driver also cannot see these situations; The passenger that on the left side is got off, when getting off, the highway on car door both sides all is their sight line blind area; When car was trailed truck and travelled, blocking of lorry can cause the sight line blind area; During meeting, behind the other side's car the sight line blind area of oneself; It is super during to preceding headstock to overtake other vehicles, and the front truck front is exactly the sight line blind area of overtaking other vehicles.3, the road conditions blind area of causing: in the urban district and villages and small towns road cross, place, tunnel, front door etc., because the blocking of buildings, vehicle driver or pedestrian are in the sight line blind area, and both sides are difficult to see the other side; The vehicle of last abrupt slope, mistake arch bridge, the sight line blind area is also caused on the abrupt slope of front easily; The building of intersection, curve inner side, the woods or massif etc. objectively form the sight line blind area, if the line road occupying is travelled or come into unavoidable confrontation and do not control the speed of a motor vehicle in advance more, the possibility of intersection-type collision will occur.4, the blind area that night, car light or inclement weather caused: night is during two-way meeting, if vehicle uses high beam, will cause dazzling the eyes of driver, cause the driver can only see the general situation of sending a car in front road conditions and opposite, the outstanding car of super wide car or tote is difficult for anxious discovery early outward, and at night, back car uses high beam also may cause the front truck driver to dazzle the eyes, night, car light irradiation light was limited, and the sight line blind area of existence is more; Misty rain weather, low visibility, the place ahead misty rain road is exactly the sight line blind area.It is many in sight line blind area, mist road that a chain of collision takes place highway.
Driving or radar for backing car are housed on automobile at present usually, can in short distance, remind the driver, but it can only remind 2 meters with interior barrier, remind distance too short, and or insufficient sensitivity, or price is expensive partially, and little for the potential safety hazard help of transport solution blind area, generally speaking, effective traffic blind area reminding device does not appear at present as yet.
The utility model content
The purpose of this utility model provides a kind of effective traffic blind area reminding device, the situation of blind area in time can be fed back to the driver.
Traffic blind area reminding device of the present utility model comprises transmitter, infrared sensor, receiver, amplifying circuit and attention device.
Preferably,
In the traffic blind area reminding device of the present utility model, said infrared sensor is a pyroelectric infrared sensor.
In the traffic blind area reminding device of the present utility model, said transmitter is a wireless launcher, and said receiver is a wireless receiver.
In the traffic blind area reminding device of the present utility model, said attention device is a LED acousto-optic warning device.
Principle of work of the present utility model is: traffic blind area reminding device can responsive objects in certain zone when mobile caused infrared radiation change, and can make monitoring alarm generation alerting signal, thereby finish warning function.Specifically, the pyroelectric infrared sensor in the traffic blind area reminding device all can produce the invisible light of a kind of naked eyes at all objects that temperature is higher than absolute zero degree centigrade, is called infrared ray.Its wavelength coverage is between 0.76～1000 micron.The high more infrared ray that then sends of temperature is strong more.The pyroelectricity element that utilizes pyroelectric crystal to make can be surveyed this ultrared a kind of infrared sensor exactly.It is a kind of passsive sensor, if having the people the zone in the activity it just can detect infrared ray.Output terminal will be exported high level when pyroelectric infrared sensor detects people movable, can start alarming device through amplifying circuit again.Utilize the pyroelectric infrared sensor induction region can be greater than 50 square metres.
The utlity model has following technique effect:
1, simple in structure, with low cost;
2, come inducing moving objects by infrared ray, highly sensitive;
3, existence that just can inducing moving objects in tens of meters scope feeds back to the driver rapidly with signal in less than one second time, and its operating distance is much higher than car radar, has improved traffic safety greatly.
Description of drawings
Come the utility model is described in further detail below in conjunction with specification drawings and specific embodiments.
Fig. 1 is the structural representation of traffic blind area reminding device of the present utility model;
Fig. 2 is the circuit diagram of traffic blind area reminding device of the present utility model.
Wherein, 1 is wireless launcher, and 2 is pyroelectric infrared sensor, and 3 is wireless receiver, and 4 is amplifying circuit, and 5 is LED acousto-optic warning device.
Embodiment
As shown in Figure 1 and Figure 2, traffic blind area reminding device of the present utility model comprises wireless launcher 1, pyroelectric infrared sensor 2, wireless receiver 3, amplifying circuit 4 and LED acousto-optic warning device 5.
Traffic blind area reminding device of the present utility model is in when work, can be installed in to be used to remind the driver in the car, also can be installed on the road that has traffic blind area, is used to remind the pedestrian.After wireless launcher 1 detects in the blind area reaction of moving object heat energy by pyroelectric infrared sensor 2, arrive wireless receiver 3 by pyroelectric infrared sensor 2, signal through amplifying circuit 4 amplifies the switch of opening LED audible-visual annunciator 5, reminds driver or pedestrian in time to tackle situation.
