Abstract
The utility model discloses a kind of intelligent traffic lamp, comprise DC power supplier, single machine unit, be connected to the numeral method unit that single machine unit control output end shows for four direction; The control input end of single machine unit is connected with the infrared human body heat releasing electric transducer signal output part being arranged on zebra crossing two ends, crossing respectively, and the control output end of single machine unit is connected with the voice alerting unit input end being arranged on zebra crossing two ends, crossing respectively; DC power supplier is powered to single machine unit and voice alerting unit by cable; The push-button unit for adjusting numeral method unit display state is also connected with in the control input end of single machine unit.The utility model advantage is to reduce pedestrians travel's traffic cross-road of not observing traffic rules and regulations, and gives blind person, achromate with the stop-light state of real-time prompting crossroad simultaneously, helps their safety current smoothly.The utility model structure is simple, and practicality is stronger.
Description
Technical field
The utility model relates to traffic lights, especially relates to intelligent traffic lamp.
Background technology
At present, the existing traffic lights overwhelming majority adopts traditional traffic signal control system, namely adopts regular time to control red, green, yellow three kinds of different LED luminotron rotations display, for the current instruction to vehicle and pedestrian at road two ends, crossing.Its deficiency existed does not consider the emergency situations and actual state (as blind person, the personnel suffering from colour blindness, the illegal personnel etc. made a dash across the red light) that occur in actual traffic, therefore there is very large potential safety hazard, have impact on efficient, the smooth and easy operation of road traffic, and cause taking place frequently of traffic hazard.
Summary of the invention
The utility model object is to provide a kind of intelligent traffic lamp.
For achieving the above object, the utility model takes following technical proposals:
Intelligent traffic lamp described in the utility model, comprises DC power supplier, single machine unit, is connected to the numeral method unit that described single machine unit control output end shows for four direction; The control input end of described single machine unit is connected with the infrared human body heat releasing electric transducer signal output part being arranged on zebra crossing two ends, crossing respectively, and the control output end of single machine unit is connected with the voice alerting unit input end being arranged on zebra crossing two ends, crossing respectively; Described DC power supplier is powered to single machine unit and voice alerting unit by cable; The push-button unit for adjusting numeral method unit display state is also connected with in the control input end of single machine unit.
The utility model advantage is to reduce pedestrians travel's traffic cross-road of not observing traffic rules and regulations, and gives blind person, achromate with the stop-light state of real-time prompting crossroad simultaneously, helps their safety current smoothly.The utility model structure is simple, and practicality is comparatively strong, brings conveniently to people's trip.
Accompanying drawing explanation
Fig. 1 is circuit principle structure block diagram of the present utility model.
Embodiment
As shown in Figure 1, intelligent traffic lamp described in the utility model, comprises DC power supplier 1, single machine unit 2, is connected to the numeral method unit 3 of single machine unit 2 control output end; Single machine unit 2 is by master control AT89S51 chip as kernel control chip, and periphery adds a clock circuit module and reset circuit module, for master control AT89S51 chip is just providing normal work schedule; Numeral method unit 3 is made up of to nixie display, south orientation nixie display and north orientation nixie display the east orientation nixie display for showing four direction red, yellow, and green indicator signal, west; The two ends of crossroad zebra crossing are respectively arranged with infrared human body heat releasing electric transducer 4 and voice alerting unit 5, the detection signal output terminal of each human body pyroelectric infrared sensor 4 is connected with the control input end of single machine unit 2 respectively, the input control end of each voice alerting unit 5 is connected with the control output end of single machine unit 2 respectively, and voice alerting unit 5 is made up of WT588D speech chip and loudspeaker; DC power supplier 1 is powered to single machine unit 2 and voice alerting unit 5 by cable; Also be connected with the push-button unit 6 showing state for adjusting numeral method unit 3 in the control input end of single machine unit 2, push-button unit 6 is made up of keyswitch K1, K2, K3.
Utility model works principle is summarized as follows:
In order to prevent pedestrian running red light, adopt infrared human body heat releasing electric transducer to detect with or without pedestrian running red light, on every bar walkway, a human body pyroelectric infrared sensor is installed at two ends place respectively, such as: when walkway, north-south be in red light forbidden period have pedestrian by time (the Received signal strength end conductively-closed of the infrared human body heat releasing electric transducer now on East and West direction walkway), infrared human body heat releasing electric transducer exports to single machine unit 2 one high level, the control output end of single machine unit 2 exports control signal to voice alerting unit 5, namely voice alerting unit 5 sends phonetic warning term such as " red interval please don't make a dash across the red light " etc., East and West direction walkway voice alerting unit 5 sends voice message term such as " during green light simultaneously, please safe passing " etc., to go across the road pedestrian especially blind person and achromate with prompting.
In order to not affect the normal life of surrounding resident, voice alerting unit 5 can be set in be brought into use morning 7, and night 9 closes automatically; Simultaneously also can according to concrete crossroad access traffic conditions, carry out the switching setting of indicating status, such as, time less, the traffic of that night upper vehicle is not crowded, by the K1 key assignments in push-button unit 6 be amber light flicker, can unrestrictedly pass through in south, north, east, west, can proper extension traffic lights current time by K2 key, the traffic current time can be shortened by K3 key.
