摘要
基于AVR单片机ATmega32和SD卡研制了大容量数据存储的塔机黑匣子。该黑匣子应用DXZ型多功能行程限位器测量塔机吊重的高度和幅度,应用BLR-1型称重传感器测量吊重质量,利用编码器测量塔机的回旋角度,采用EC21B型风速传感器记录实时风速,选择PCF8563产生日历时钟,选用大容量SD卡存储塔机运行状态数据。黑匣子既可以实现对塔机运行状况数据的实时记录又具有预报警、强制断电以及历史数据回放等功能。
A tower crane black box is developed based on an AVR microcontroller ATmega32 and an SD card.The black box has the function of large-capacity data storage.The DXZ multi-function trip recorder stoppers are used to measure the height and the amplitude.The lifting weight is acquired by a BLR-1 weight measuring sensor.The encoders are applied to get the angle of the tower crane swing.The real-time wind speed is obtained by using a wind speed sensor EC21B.PCF8563 is selected as the calendar clock.The data of tower crane operating status are saved by the large-capacity SD card storage.The black box can store the real-time data of the tower crane operation status and can playback the historical data.This box also has functions of pre-alarming and forcibly power-off.
