АВТОМАТИЗИРОВАННАЯ СИСТЕМА ПРЕДУПРЕЖДЕНИЯ О ПРЕПЯТСТВИЯХ НА БАЗЕ УЛЬТРАЗВУКОВОГО ДАТЧИКА И МИКРОКОНТРОЛЛЕРА

The purpose of this work is devoted to the development of an automated warning system on the obstacles people with poor vision on the basis of the ultrasonic sensor and the microcontroller. The system gives audible signals when it detects obstacles. The method by which this system works is to measure the time between the emission of the ultrasonic signal and reception signal reflected from the obstacle using an ultrasonic sensor MA40S4S and then calculating the distance to an obstacle and an audible signal whose frequency depends on the distance between the obstacle and man. Microcontroller - XS1-L1-64. The result: the development of this system is not yet over, but in this study we were able to develop a block diagram of the system, consider the main components, as well as to write and test the program for the development board XMOS XK-1A Development kit, on-board microcontroller which is XS1-L1 -64, which gives a sound signal whose frequency depends on the distance to the obstacle. The tests used sensor HC-SR04.
