the utility model has the advantages that:
1. this intelligent traffic light can change the traffic lights red light stand-by period in real time according to vehicular traffic, substantially increases out line efficiency, can also adjust the display brightness of traffic lights, saved the energy according to vehicle flowrate and light intensity.The utility model and change green into cyan but for protanopia anerythrochloropsia patient, traffic lights just becomes and easily differentiated.
2. can also there is corresponding adaptability to changes to emergency condition, can in case of emergency for the special cars such as police car, ambulance, fire truck be saved time.
3. change the green light of pedestrian traffic lamp into cyan lamp, make protanopia anerythrochloropsia patient can be more prone to differentiate traffic lights, and do not affect normal person.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is the structural representation of the utility model moving traffic lamp;
fig. 2 is the structural representation of the utility model pedestrian traffic lamp;
fig. 3 is schematic block circuit diagram of the present utility model;
fig. 4 is workflow diagram of the present utility model.
Embodiment
for making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
embodiment:
the structure showing moving traffic lamp of the present utility model as Fig. 1 comprises infrared sensing device 1, optical sensing means 2, GPRS communication module 3, processor 4 and GPS device 5.
the structure that Fig. 2 shows pedestrian traffic lamp of the present utility model comprises red colored lamp 6 and cyan lamp 7.
pedestrian traffic lamp green light changes cyan lamp into, in most human eye, green and cyan is very close, can't affect the driving of these people, but for protanopia anerythrochloropsia patient, green is yellow in their eye, redness is also yellow in their eye, and cyan is blue in their eye, like this, they just relatively easily can tell the situation of traffic lights.
as shown in Figure 3-4, infrared sensing device this direction vehicle stand-by period will at the end of, the radiant quantity sensed is converted to number of vehicles, and collecting the distance of radiant quantity is 150 meters, and these data are passed to processor.Processor is according to obtained data, and calculate these vehicles by the required time, display system net result being passed to charactron and traffic lights shows.The radiant quantity detected in 150 meters when infrared sensor is less than threshold value, and processor also can control the brightness of display system, is adjusted to minimum.
optical sensing means is by collection light intensity data and pass to processor, processor makes corresponding regulation and control according to the brightness of these data to display system, shows with saves energy more humanely.The brightness of traffic lights display system can be set to three kinds, be respectively bright, in, dark.
gPRS communication module and GPS device are used for communicating with the car-mounted terminal of the special car such as police car, ambulance, fire truck, can couple together, realize real-time Data Transmission with traffic system.When an emergency happens, police car, ambulance, the car-mounted terminal of the special cars such as fire truck sends out an emergency signal, the information that traffic lights in surrounding 500 meters can provide according to car-mounted terminal, the traffic (be divided into and block up and unimpeded two kinds) at crossing residing for position relationship between this traffic lights and this vehicle and this traffic lights is sent to this vehicle by GPRS communication module, driver can determine suitable travel route according to the information received, and from when the traffic lights distance on this travel route is within 150 meters send urgent signal to traffic lights, control the green light that traffic lights lights this direction, and certain transit time is set.
signal transmissions between all modules and processor all adopts digital baseband signal transmission mode to transmit.Processor can select MCU, and infrared sensing device can select the infrared sensor of radiometer function, and optical sensing means can select ambient light sensor.
the control method of traffic lights of the present invention comprises the steps:
(1) traffic lights normally runs, and as do not received urgent signal, then performs step (2), otherwise processor controls traffic lights, and make this direction become green light, transit time is 150 car required times.
(2) the extraneous light intensity of light sensors, be divided into bright, in, dark Three Estate, display system controls the brightness of self according to the difference of extraneous light intensity, be divided into equally bright, in, dark Three Estate, when ambient light grade is bright, during display system brightness degree is, when the external world is in brightness degree, during display system brightness degree is, when ambient light grade is dark, display system brightness degree is bright.
(3) infrared sensor detects, and when radiant quantity is less than threshold value, display system brightness degree is dark, otherwise forwards step (4) to.
(4) processor calculate this direction according to the data that infrared sensor obtains wait vehicle needed for by the time, shown by display system.
for realizing above-mentioned control, can setting command mode as follows:
