【摘要】：随着国家经济的快速发展，塔机因具有吊臂长、塔身高、吊重大、作用范围广、工作效率高等技术特点，在现代化建筑领域中得到了广泛的应用。然而由于自身设计缺陷或者违规操作等原因，塔机重大安全事故的发生率居高不下，从而造成重大的人员伤亡和经济损失。因此，在塔机上安装安全保护装置，实时监测其运行状态就显得也越来越有必要。随着传感器和检测技术的发展，如今施工设备的绝大多数参数都能被转变为电信号，再通过仪器仪表显示出来。同时，借助各种无线传输技术和互联网技术，将运行参数远程传输，以便管理部门对设备进行安全管理，这将使其工作更加安全平稳，控制更加准确，这对于提高作业效率，避免事故和对事故分析都具有重要作用。本文完成了基于GPRS的塔机远程监测系统的分析与研究、硬件电路及软件的设计。在线监测终端采用多CPU处理方式，主CPU采用Silicon Lab公司的C8051F120实现数据的采集、处理及显示；从CPU采集GPS定位信息和将主CPU采集到的数据进行GPRS无线传输；存储模块也采用单独的CPU做成“黑匣子”结构，可利用上位机软件读取里面的数据进行分析来作为事故后的证据。在线监测终端以数值方式实时显示塔机运行的各个状态参数，当参数值超过限定值时，可自动预报警来提醒操作人员，防止误操作，起到安全保护的作用。同时，各参数数据可通过GPRS无线传输方式传到地面远程监测中心，用户通过客户端软件可实时了解塔机的现场运行状态、工作环境及地理位置等信息，对违规操作提出报警，大大方便了工程监管人员对塔机工作状态的监视；同时，各参数的历史工作记录存储于数据库中也可作为塔机事故责任认定的重要依据。现场用户反馈表明，，该塔机远程监测系统具有成本低、稳定性好、实时监测、定时上报监测数据、信息显示直观、基于互联网自动管理等特点，为加强塔机安全运行监管工作提供了有效的手段和措施。
[Abstract]:With the rapid development of national economy, because of the long boom crane, tower crane, height, wide range, high technology efficiency, has been widely used in the field of modern buildings. However, due to the design defects or irregularities, the high incidence of major accidents caused by tower machine. Significant casualties and economic losses. Therefore, the safety device installed in the tower crane, real-time monitoring of the operation status becomes more and more necessary. With the development of sensor and detection technology, now the construction equipment in most of the parameters can be transformed into electrical signals, and then displayed through the instrumentation. At the same time. With the help of a variety of wireless transmission technology and Internet technology, the operating parameters of remote transmission, so the management of the safety management of equipment, which will make the work more stable and safe, control The system is more accurate, which plays an important role in improving operation efficiency, avoiding accidents and accident analysis.
This paper completed the analysis and research of the remote monitoring system of tower crane based on GPRS, the design of hardware circuit and software. The online monitoring terminal uses multi CPU processing, the main CPU using Silicon Lab's C8051F120 to realize data acquisition, processing and display; acquiring GPS positioning information and the data acquired by CPU GPRS wireless transmission from CPU; storage module also uses a separate CPU into a "black box" structure, using software toread. Data were analyzed as evidence after the accident.
The online monitoring terminal in digital real-time display of various parameters of the tower crane, when the value exceeds the limit value, can automatically alarm to alert the operator to prevent misoperation, play a security role. At the same time, the parameters of data through GPRS wireless transmission to the remote monitoring center of the ground, the user can know the real-time the tower crane running through the client software, working environment and location information, put forward an alarm for illegal operations, greatly facilitate the engineering supervision personnel to monitor the working status of the tower crane; at the same time, the parameters of the HistoricalRecords are stored in the database can also be used as an important basis for towercrane accident.
Field user feedback shows that the tower crane remote monitoring system has the characteristics of low cost, good stability, real-time monitoring, timely reporting of monitoring data, intuitive information display, and automatic management based on Internet. It provides effective means and measures for strengthening the supervision and operation of tower crane's safe operation.
