Description
Technical field
The utility model relates to overlength distance correlation infrared photoelectric sensor, and the control to traffic light reminding device by chip microcontroller.
Background technology
In daily traffic administration, corner need fast response time, device that resolution is high to remind to be about to the to turn people of walking, to reduce the generation of traffic accident.
At present corner is equipped with the convex mirror with reflection function conventionally, and such device can play certain prevention effect for traffic hazard, but also has some limitations: such as the visual impairment person who causes for myopia or other reasons, identification difficulty is larger; Dust and the weakening of other fouling product to mirror reflecting effect, also significantly reduced the prompting effect of installing.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of L-type road collision avoidance system that turns round, by real-time detection vehicle and pedestrian's passage situation, to reminding by traffic lights towards the turn round close people of direction or car.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of L-type road collision avoidance system that turns round, it is characterized in that: comprise two covers and detect, alarm set, every cover detects, alarm set comprises sensor detection module, kernel control module, driver module, whether described sensor detection module records and has vehicles or pedestrians to pass through with two sensors, signal is passed to kernel control module by corresponding MAX232 chip, kernel control module adopts single-chip microcomputer process information, judge vehicle heading and pedestrian's direction of travel according to gained information, control traffic light device, driver module utilizes optical coupled switch to drive relay, Single-chip Controlling signal is converted to the control signal of traffic light device.
As a kind of improvement of the present utility model, described sensor is Photoelectric infrared switch.
As a kind of improvement of the present utility model, described two covers detect, alarm set is at right angles arranged, and are distributed in horizontal ends and the vertical end of L-type road.
The beneficial effects of the utility model are:
(1) discrimination degree is high: this device has solved the limitation of the mirror with reflection function, can clearly offer pedestrian's authentic communication, has reduced the probability that traffic hazard occurs;
(2) strong adaptability: this device, under some rugged surroundings such as wet weather, because the visuality of traffic light device is strong, still can offer pedestrian's information accurately;
(3) promptness: the transducer sensitivity of selecting is all very high, detects that signal just passes to single-chip microcomputer immediately, and single-chip microcomputer can be exported control signal immediately according to internal processes, can within the shortest time, control traffic light device.
Brief description of the drawings
Fig. 1 is system chart of the present utility model.
Fig. 2 is system scheme of installation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
As shown in Figure 1, a kind of L-type road described in the utility model turn round collision avoidance system comprise two covers detect, alarm set, detect, alarm set installation site as shown in Figure 2.
Described sensor uses overlength distance correlation optoelectronic switch E18-8MNK: whether be used for record has vehicle to pass through the time of passing through with single unit vehicle.
Described chip MAX232: single supply level transferring chip, be used for increasing the transmission range of signal, make signal undistorted.
Described single-chip microcomputer model STC89C52: single-chip microcomputer receives the input signal of input port, exports control signal according to internal processes to output port.
Can install separately power module additional: power to whole system.
Described optical coupled switch H92B4: by Single-chip Controlling, pilot relay work.
Described relay SRD-12VDC-SL-C: by the output terminal output signal of single-chip microcomputer, thereby control traffic light device.
(1) sensor detection module: taking the system 1 in Fig. 1 as example, whether sensor 1-1 and sensor 1-2 are used for recording has vehicle process or pedestrian to pass through, once vehicle process detected, single-chip microcomputer 1-1 response is interrupted, and controls the switching of traffic light device;
Sensor described in the utility model uses overlength distance correlation Photoelectric infrared switch, overlength distance correlation Photoelectric infrared switch is a kind of overlength distance correlation photoelectric sensor, and its object is not limited to metal, and this range detection sensor is far away, measurement range is 0-8M, and measurement range is adjustable.
(2) kernel control module: adopt single-chip microcomputer process information, and judge vehicle heading and pedestrian's direction of travel according to gained information, control traffic light device, single-chip microcomputer 1-1 acquisition and processing information, the traffic lights of controlling traffic light device 1-1 switch, in the time there is no Vehicle Driving Cycle, the green light of traffic light device 1-1 is opened, pedestrian's P Passable; When having vehicle through out-of-date, the red light of traffic light device 1-1 is opened, and pedestrian should halt wait green light, and vehicle turns round, and green light is opened; In like manner, in the time there is no walk, the green light of traffic light device 2-1 is opened, open to traffic; In the time having pedestrian to pass through, the red light of traffic light device 2-1 is opened, and should note the pedestrian of corner when vehicle turning.
(3) driver module: we utilize optical coupled switch to drive relay, Single-chip Controlling signal are converted to the control signal of traffic light device.
The course of work of the present utility model is:
As shown in Figure 2, comprise sensor 1-1, sensor 1-2, traffic light device 1-1, road turns round after anti-collision reminding device powers on, and device is just started working, there is no vehicle through out-of-date, be that sensor 1-1 has not detected that vehicle is through out-of-date, the green light of traffic light device 1-1 is opened, and now pedestrian can safe passing, when sensor 1-1 has detected vehicle process, single-chip microcomputer 1-1 just can enter interruption, opens the red light of traffic light device 1-1, and pedestrian should halt wait.If wherein pedestrian is first after sensor 1-2 during through sensor 1-1, single-chip microcomputer 1-1 can't make response, can effectively judge like this vehicles or pedestrians direction of passing through.
Two covers described in the utility model detect, alarm set is at right angles arranged, and are distributed in horizontal ends and the vertical end of L-type road, the people to point of crossing direct of travel of L-type road or vehicle all can be monitored.
