基于手势控制无线小车运动系统的设计
|
摘要
设计了一种采用重力感应的手势控制小车的运动系统。该系统包括手持端和小车端两部分。手持端包括STM32控制器,ADXL345加速度传感器,ZigBee无线发射模块;小车包括STM32控制器,电机和舵机驱动单元,ZigBee无线接收模块;手持端的STM32控制器通过采集加速度传感器的数据,得到多个方向的手势变化,通过无线模块发送指令信息给小车,小车与手持端的ZigBee模块配置在同一个网络,接收来自手持端的指令信息,然后根据不同的指令信息驱动电机和舵机实现小车的前进、后退、转弯等方向的运动。这种采用重力感应并结合无线收发方式下的非接触式控制方式,具有反应灵敏、动作快速的特点,同时具有较为广泛的应用场景。
A motion control system based on gravity sensor is designed. The system includes a handheld end and a car end. The handheld terminal comprises a STM32 controller,a ADXL345 acceleration sensor,a ZigBee wireless transmitting module,the small car includes a STM32 controller,a motor and a steering gear driving unit,and a ZigBee wireless receiving module. The STM32 controller on the handheld side can acquire the data of the acceleration sensor and get the gesture change in many directions,and send the instruction information to the car through the wireless module. The car and the ZigBee module of the handheld end are configured on the same network. Receive the instruction information from the handheld end,then drive the motor and steering gear according to the different command information to realize the movement of the car in the direction of forward,backward,turn and so on. This non-contact control mode which adopts gravity induction and wireless transceiver,has the characteristics of sensitive response and fast action,and has a wide range of application scenarios at the same time.
