Abstract

To need the requirement of measuring the grain quantity in the barn, the pressure sensors are mounted on the ground and the wall of the barn, and the grain quantity can be calculated by using these measurement values. To realize the data transmitting reliability and real time, the design proposal of the measurement node of the CAN-bus by using the chips of AT89C51 and the SJA1000 is put forward, and the design of software and the hardware of the node is given. To verify the effectivity and the reliability of the measurement node, some experiments are done, the results shown that, the measurement error is no more than 3% under the conspicuous level is equal to 0.05, the grain quantity can be measure by this system completely.

基于can总线的粮食数量监控系统测量节点的设计

为了满足测量粮仓内粮食数量的要求，将压力传感器安装在粮仓的地面和墙壁上，利用这些测量值计算出粮仓内的粮食数量。为实现数据传输的可靠性和实时性，提出了基于AT89C51和SJA1000芯片的can总线测量节点的设计方案，并给出了该节点的软硬件设计。为了验证该测量节点的有效性和可靠性，进行了一些实验，结果表明，在显著水平= 0.05下，测量误差不大于3%，该系统完全可以测量粮食数量。
