吊称单面直显电路原理图，将拉力传感器信号转变成LED数码管显示-Was suspended, said one side of the circuit diagram, the tension sensor signal into a LED digital display

根据随机振动法索力测量的原理，采用MMA8452Q加速度传感器模块来采集信号,STC89C52单片机为控制芯片测量斜拉索的拉力。-According to the principle of random vibration Faso force measurement, MMA8452Q acceleration sensor module to capture the signal, pull control chip measure

数据采集卡采集拉力值，与预先设定的拉力值进行比较，然后PID运算，控制相应的PWM占空比输出，最终控制电机的速度(The data acquisition card collects the pull value and compares it with the pre-set pull value. Then the PID arithmetic is used to control the output of the corresp
