摘要
Bus route detecting smart system for blinds is a new technology. This system has two parts one is hand held device of blinds connected to ear phone other one is connect to every bus. Every bus is generated by a particular code or data to send nearest handheld devices and passes to all nearest persons This technology is developed with the help of embedded system. These two devices are communicated with the help of Radio Frequency system and also used WIFI.One device bus module is installed inside the bus. Once at a bus stop, the user presses the query button on the handheld module to obtain route numbers of the buses in this system. These data are read via head phone in the user module. The select button can be pressed multiple times to trigger the guiding voice output from the bus. Microcontroller compares the GPS readings and stored readings. When both, the readings match, the microcontroller switches the control to the GSM module. This GSM module sends SMS alerts to the passengers, whose mobile numbers are already stored in the microcontroller. For example consider three points A, B, C along a path whose latitude and longitude positions are already stored in the microcontroller. When the vehicle starts, GPS module sends the longitude and latitude position details of the vehicle to the microcontroller. Microchip"s PIC.micro 8bit MCU"s offer a price/performance ratio that allows them to be considered for any traditional 8 bit MCU application as well as some traditional 4 bit application, dedicated logic replacement and low end DSP applications. These features and price performance mix make PIC micro MCU"s an attractive solution for most applications. Here we employ. PIC16F877A Microcontroller which receives data via a RS 232 converter and sends the information through the transmission logic unit. This technology is developed with the help of embedded system. These two devices are communicated with the help of Radio Frequency system and also used WIFI. One device bus module is installed inside the bus. Once at a bus stop, the user presses the query button on the handheld module to obtain route numbers of the buses in this system. These data are read via head phone in the user module. The select button can be pressed multiple times to trigger the guiding voice output from the bus. Microcontroller compares the GPS readings and stored readings. When both the readings match, the microcontroller switches the control to the GSM module.
