Embodiment Construction

[0014] like figure 1 As shown, the infrared induction voice prompt system system of this embodiment symmetrically fixes the emitting column 9 and the receiving column 10 at the sidewalk 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 must be in the same position. On the horizontal plane, in order to prevent false triggering of signals caused by debris such as fallen leaves and wind-blown plastic bags, it is best to install 2 pairs of infrared transmitters 7 (model PZ-M51) and infrared receivers 8 ( Model PZ-M51), arranged up and down, the infrared transmitter 7 is installed on the emitting 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 infrared light emitted by the transmitter It can be received by the receiver, and the detection distance is up to 1...

Abstract

The invention relates to an infrared induction voice prompt system for city crossings. The technical problem to be solved by the present invention is to provide an infrared induction voice prompt system for urban crossings, which aims to improve the consciousness and safety of pedestrians passing through the crossings. , good sound quality. The technical solution to solve this problem is: an infrared induction voice prompt system for city crossings, which is characterized in that the system symmetrically fixes the transmitting column and the receiving column at the edge of the sidewalk at the intersection with traffic lights through the upper base plate and the lower base plate. There are 1 to 2 pairs of infrared transmitters and infrared receivers; the control circuit board is installed in a waterproof electric control box, and is connected to the infrared transmitter and infrared receiver through wires, and a fan is installed in the electric control box. The circuit board is externally connected to a waterproof column speaker. The invention can be used for crossings where traffic lights are installed in cities.

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...
