为解决集成式儿童安全座椅的智能远程控制问题，在已经搭建好的集成式儿童安全座椅平台下，以“儿童约束系统安全乘坐高度”为依据，基于Android平台和MC9S 12SX128单片机开发其控制系统，包括蓝牙通信模块、电机控制模块、信号采集模块、记忆存储模块、脉冲计数模块、行程保护模块、省电模块等。该控制系统通过Android平台以蓝牙通信的方式给单片机发送数据指令，指令包括身高数据和控制指令，单片机根据指令自动控制座椅高度。采用构件法思想开发一套控制系统硬件电路和控制程序，并与手机客户端进行硬件在环试验，通信试验中指令信号接收准确率为100％，座垫理论与实际上升高度误差最大值为3．5％。%Abstar ct:The paper developed a controlling system on the integrated child safety seats platform which was already built , taken the “child restraint systems safe height” as the protection mechanism and based on the Android platform and MC 9S12SX128MAA microcontroller .The controlling system send data to the microcontroller via bluetooth based on Android platform and the data in -cludes the height of child and the controlling commands , the MCU will automatically adjust the height of the seats according to the instructions .The system has developed a complete set of hardware circuit and controlling programs and has made the hardware ring test with the phone clients , through which the signal reception accuracy was 100%and the maximum error between the theory and the practical height of the seat is 3.5%.
