In addition to the bus-stop system and out of the station bus stop outside , how about to remind passengers to the front of the station names , as well as to those vulnerable groups effectively convey the station information to facilitate their travel , is also an important part of the smart -stop system . The design is mainly to address how easily and accurately instruct passengers arriving problem with the human voice simulation and forecasting stations reporting station , reported on the number of stations and station name and station name for text display and voice message recording station name selection control function. The system includes a microcontroller module , speech synthesis circuit , station number , station name display module , infrared interface circuit , reset circuit and power systems . STC12 microcontroller to control the use of speech synthesis chip and LCD modules . Speech synthesis chip SYN6288 , using simulated data is stored directly patented semiconductor memory technology , the upcoming analog voice data is written directly to a single storage unit , eliminate the need for A/D, D/A conversion , and therefore better able to reproduce the natural effects of real speech avoid the quantization noise and distortion generally solid voice circuits because quantization and compression caused . With LCD display , through the construction of model building simulation systems , access to relevant information relat
