基于MSP430单片机的智能压路小车设计

为了减少在道路修建时压路工人受路面的恶劣环境影响的问题,在此设计了智能无人压路小车来代替有人驾驶压路车。该小车由红外传感器模块实现对车体前方环境检测,以MSP430G2553单片机为控制核心,对传感器所采集到的数据进行比较处理,同时通过控制L298驱动模块实现直流电机的正反转,从而实现车体的移动、转向、变轨等动作。另外采用无线收发模块用以实现压路小车的无线控制,最终可实现智能压路小车的自动控制和遥控控制2种工作模式。

Design of intelligent roller based on MSP430 microcontroller

In order to reduce the harm to workers’health by the harsh environment when roads are constructed,an un-manned intelligent roller was designed instead of manned roller. An infrared sensor module is used to detect the front environ-ment. The microcontroller MSP430G2553 is taken as the control core to compare and process the data collected by the sensor, and control the L298 driver module to realize the forward and reverse rotation of the DC motor for movement,turning,track change and other actions of the roller. In addition,a wireless transceiver module is used to control the roller. The two working modes（autonomous control and remote control）for the roller were realized ultimately.
