基于单片机的风速风压测量系统的设计 本文在了解压力传感器工作原理以及单片机相关知识的前提下，介绍了一种 新型的风速风压测量系统。该系统采用单片机技术，由压力传感器采集数据，对传 感器模拟信号提取放大，并进行模数转换，单片机负责控制系统各部分器件的工 作并对数字信号进行处理。然后将压力信息显示在LED接收血板上，同时将信息 经串口发送给上位机软件，并由上位机显示出来。该系统以AT89S52作为微处理器, 具有强大的数据计算处理能力及控制能力，此外由于其内部集成了多种硬件电路 接口，有效地降低了成本，减小了装置体积。在压力传感器部分，选用霍尼韦尔 公司的传感器，型号为24PCEFH2Go 关键词：单片机；风压；风速 Abstract In this article, with the knowledge about the work principle of the pressure sensor and knowledge about the single ? chip computer technology, wc introduce a new system of wind pressure and speed measurement, based on single-chip compute匚 The system uses microcomputer technology, the data collected by the pressure sensor, the sensor analog signal extraction amplification and for analog-digital conversion, microcomputer control system for the work of the various parts of the device and digital signal for processing. Then the pressure of information displayed in the LED panel on the receiver, while the information sent to the host computer via serial port software, shown by the host computer. As microprocessors of the system, AT89S52 has powerful data processing power and control ability, in addition to its internal integration of a variety of hardware interfaces, effectively reduces the cost and reduce the device volume. Some of the pressure sensor, use HoneywelPs sensor model 24PCEFH2G.
