As shown in Figure 5, described speech recording and reproducing plate 3 comprises a voice control chip MCU (model BMP5008), 2 relay indicating light LED, REC key and PLAY keys, carry MIC/LINE IN circuit input port on the plate, the FLASH of plug-in different capabilities on the plate can obtain from 30 seconds～32 minutes recording capacity.Speech recording and reproducing plate 3 has 8KHZ and two kinds of frequencies of 12KHZ to select for the user, and the recorded message power down can not lost.Carry mu balanced circuit on the plate, power supply is that DC12V voltage is directly imported.Chip on board carries the 7.5W power amplifier, and the triggering function that the user can freely define 6 I/O mouths is that single hop triggering playback still is 63 (84210 parallel encoding) address selections playback.
The FLASH record of voice control chip MCU has two sections music:
First section music is green light helpful tips voice (the P00 port is to GND): green light is bright, please passes through as early as possible.
Second section music is red light helpful tips voice (the P01 port is to GND): you have made a dash across the red light, and ask outside the line of retirement.
Principle of work of the present invention is: when the traffic lights red light lighted, if any a pedestrian running red light, the infrared induction system just triggered and just detects pedestrian signal, and this signal is sent to time-delay plate circuit; Then trigger voice controller.Red light friendship voice (about record length 2.5 seconds) are play, successively make a dash across the red light if any several pedestrians, it is just effective to have only first pedestrian to respond to, other several pedestrian's inductions are all invalid, after red light friendship speech play is finished by the time, there is the pedestrian running red light induction just effective again, makes red light friendship voice continue to play.Could guarantee that like this pedestrian more clearly listens the voice suggestion of complete traffic lights friendship at place, traffic lights crossing.
When the traffic lights green light lights, this green light signals is by time-delay plate circuit triggers voice controller, make green light helpful tips voice (about record length 2.5 seconds) loop play, by street crossing, infrared inductor is inoperative during the green light as early as possible for the prompting pedestrian.Make green light helpful tips voice (about record length 2.5 seconds) loop play, by street crossing, at this moment infrared inductor is inoperative as early as possible for the prompting pedestrian.At green light the flicker of interruption was arranged in last 3 seconds, green light signals is interrupted to be triggered 3 times, in order to guarantee in that the green light speech play is complete during this period of time, and when transferring red light to, do not play by green light the green light signals voice, therefore it is all invalid that back three interruptions trigger, it is just effective to trigger green light signals when red light transfers green light to by the time again, so must use delay control circuit shown in Figure 4.
