Embodiment Construction

[0014] As shown in Figure 1, the infrared induction voice prompt system system of the present embodiment symmetrically fixes the emitting column 9 and the receiving column 10 at the edge of the sidewalk at the intersection with traffic lights through the upper base plate 11 and the lower base plate 12, and the emitting column and the receiving column It must be on the same level. In order to prevent false triggering of signals caused by fallen leaves, plastic bags blown by the wind and other debris, it is best to install 2 pairs of infrared transmitters 7 (model PZ-M51) and infrared receivers for each system. 8 (model PZ-M5 1), arranged up and down, the infrared transmitter 7 is installed on the transmitting column 9, and the infrared receiver 8 is installed on the receiving column. Each pair of infrared transmitter and receiver must be on the same level to ensure that the transmitter The emitted infrared light can be received by the receiver, and the detection distance is up t...

Abstract

The invention relates to an infrared induction voice indicating system disposed at an urban road intersection for improving consciousness and security of passerby when passing through road intersections. The volume of indicating voice is adjustable and a loudspeaker has the advantages of waterproof, moistureproof and good tone quality. The technical proposal adopted is characterized in that a transmission column and a receiving column symmetrically are fixed to border of intersection sidewalks provided with traffic lights via an upper bottom plate and a lower bottom plate; one to two pairs of infrared emitters and infrared receivers are arranged on the transmission column and the receiving column; a control circuit board is arranged in a waterproof electric cabinet and connected with the infrared emitters and the infrared receivers via wires; a fan is arranged in the electric cabinet, and a waterproof column loudspeaker is externally connected with the circuit board. The invention can be used at an urban road intersection provided with traffic lights.

Description

technical field [0001] The invention relates to a voice prompt system through infrared induction, in particular to an infrared induction voice prompt system used for city crossings. It is suitable for crossings with traffic lights in cities. Background technique [0002] At present, the pressure on urban traffic is increasing, the traffic volume is soaring, and it is becoming more and more difficult for pedestrians to cross the road. Generally speaking, security incidents happen from time to time. At the existing crossroads, there are red, green and yellow signal lights, but there are only light prompts and no voice prompts, and the warning effect is weak. Some people who are lucky still ignore the signal lights. [0003] With the advancement and development of infrared sensors and voice control chip technology, infrared sensors have more and more functions and are more and more convenient to use. However, it is rarely used in the traffic field, especially at traffic ligh...
