基于双微处理器的传感器自动采集装置设计与实现

随着堤坝、桥梁、建筑等工程监测技术的不断发展,功能简单、通道类型单一、自动化程度低的采集装置已不能满足工程监测的系统需求。设计了以STM32F407VET6为核心处理器且具有人工比测功能的传感器数据自动采集装置,集中控制传感器的信号采集、数据存储、数据传输,任意通道均可测量振弦式、差动电阻式、标准电压或电流、数字信号等类型的传感器。并通过人工比测模块中第二微处理器的独立运用,支持读数仪数据接入、人工比测、数据实时比对及显示,提高了硬件系统的集成度和智能化程度,实现同一装置自动采集、存储、传输及人工比测多路不同类型的传感器信号。

Design and Implementation of Automatic Sensor Data Acquisition Device Based on Dual Microprocessor

With the development of engineering monitoring technology, the acquisition device of simple features, single channel type and low automation degree has been unable to meet the demand of engineering monitoring system. In this paper an automatic sensor data acquisition device which is provided with manual comparison measurement and STM32F407VET6 as the core processor is designed for signal acquisition, data storage, and data transmission. Any channel of the acquisition device has access to vibrating wire sensor, differential resistance sensor,voltage sensor, current sensor, or digital signal type sensor.Moreover, the second microprocessor of manual comparison measurement module supports other reading instrument, manual comparison measurement, and real-time display of data. The proposed device improves the integrated and intelligent degree of the hardware system, and achieve automatic acquisition, storage, transmission and manual comparison measurement of multi-channel multiplex sensor signal.
