摘要
在测控领域内,随着传感器技术和微处理器技术的发展,对传感器的精确度、可靠性要求越来越高,要求传感器具有一定的数据处理、自我检测、自我纠错能力,并且具有数据通信和扩展组网功能;为了满足这个要求,文章提出了一种基于CAN总线技术的振动传感器智能化方案,详细介绍了智能传感器节点硬件电路和固件程序设计的具体实现;对智能节点进行静态和动态测试,静态环境下传感器电压值输出为2.5V,上位机对数据处理后作图,符合实际要求;动态环境下,将传感器置于连续振动环境,数字量数据接收后经处理作图,与标准传感器波形图进行比较,满足设计要求。
With the development of sensor technology and microprocessor technology,the accuracy and reliability of sensor have been becoming more and more significant in the field of measurement and control.The sensor,equipping with certain data processing,self-testing and self correcting capability,can communicate with other nodes in the network.To meet this requirement,the paper proposes a solution of intelligent vibration sensor based on Controller Area Network and details the implementation of circuit and firmware for digital node.Test the sensor node in static and dynamic environment.The output voltage of the sensor for the static environment is 2.5 V.PC plots the chart after data processing,which is in line with actual requirements; In dynamic test,the sensor is placed in continuous vibration environment,the chart plotted by PC after data processing meets the design requirements,comparing waveforms to the standard sensor.
