Design and Realization of intelligent fire control car
Abstract
The intelligent fire car adopts STC89C52 single-chip microcomputer as the master, by the flame sensor, obstacle avoidance sensor,3 road line devices such as sensors and motor assembled. Car can realize automatic looking for fire, automatic near the fire source and the design of the core functions such as automatic fire extinguishing. In addition, the car can also be implemented in the designated area, when faced with obstacles, can avoid obstacles, and other functions.
3 road tracking module is composed of reflection type photoelectric sensor and comparator, when collected signals transmitted to the microcontroller for data processing; Obstacle avoidance module mainly consists of infrared sensor of obstacle avoidance, through infrared transmitter launch, when the receiver, then prove the obstacles ahead; Fire extinguishing module is composed of booster circuit and fire fan, again with a core of L293D motor driver module as a motor drive circuit, complete function of fire. Programming using C51 programming, after various modules assembled together, combining with the program, through the MCU control, finally completed the design of the car.
This design were introduced in detail, the principles and characteristics of various sensors, as well as on STC company produces STC89C52 performance and application. And on the basis of the analysis of intelligent fire car fire, further points out the shortcomings of the design, and then to improve.
Key words: single chip mircocomputer; sensor; obstacle avoidence; fire fighting
