【摘要】 为了测量车载土石方,针对土石方不规则的形状,利用超声波的发送和接收电路、TR4016系列传感器阵列和TI公司的TMS 2812 DSP一起构成了超声波车载土石方计量系统。对该系统的硬件设计、软件流程进行了介绍,并对实验误差进行了分析。更多还原

【Abstract】 In order to calculate vehicular earthwork and aiming at the abnormity of the shape of the earthwork,we make use of sending and receiving circuit of ultrasonic,TR4016 series electrostatic transducer array,and TMS 2812 DSP from TI Company to make up a system to measure the earthwork.This paper presents the design of the circuit and program,and also analyzes the error of experiment.更多还原
