Public bus station voice announcement system

Abstract

The invention discloses a public bus station voice announcement system which comprises a single chip microcomputer, a voice chip, a key module, a displayer, a microphone used for recording voice, a high-precision amplifier, a loudspeaker used for playing voice, a reset circuit, a crystal oscillator and a power source. The input end of the single chip microcomputer is connected with the reset circuit, the crystal oscillator, the power source and the key module respectively, and the output end of the single chip microcomputer is connected with the voice chip and the displayer respectively. The input end of the voice chip is further connected with the microphone, and the output end of the voice chip is sequentially connected with the high-frequency power amplifier and the loudspeaker. The public bus station voice announcement system is reasonable in construction cost, simple in structure and capable of reporting stations accurately.

Description

technical field [0001] The invention relates to the field of urban traffic systems, in particular to a bus voice announcement system. Background technique [0002] With the continuous development of social economy and increasingly serious environmental pollution, buses have become a vital part of urban transportation and the preferred mode of transportation for most travelers. Due to the increasing development of urban traffic construction, the previous method of manual station announcement can no longer meet the current needs. In many places, automatic voice station announcement without ticket sales has been implemented for station announcement and prompting. [0003] At present, there are mainly three kinds of voice announcement systems for buses: one is to calculate the position of the bus through the information received by GPS. Station reporting, but the cost of the equipment is high and it is difficult to determine the location of the vehicle; the other is to use radi...

Due to the increasing development of urban traffic construction, the previous method of manual station announcement can no longer meet the current needs. In many places, automatic voice station announcement with unmanned ticket sales has been implemented for station announcement and reminder.

[0003] At present, there are mainly three kinds of voice announcement systems for buses: one is to calculate the position of the bus through the information received by GPS. Station reporting, but the cost of the equipment is high and it is difficult to determine the location of the vehicle; the other is to use radio frequency identification technology, install a radio frequency transmitter on each platform, and continuously transmit signals. When the bus travels to the distance from the platform Within a certain range and when the corresponding radio frequency signal is received, the bus will automatically announce the station by voice. Compare the measured value with the set value to determine the station announcement time, which requires that the vehicle's driving route must be strictly fixed, otherwise the station announcement cannot be accurately announced
