Study on an Intelligent Monitoring Application System of Construction Machinery Qinghui, Jianmin
Abstract:In order to monitor construction machinery’s performance and quality, an intelligent monitoring application system is presented in the paper. The system makes site monitoring cell installed on every construction machinery as its terminal, GPRS (general packet radio service) as its network carriers, intelligent monitoring center as controller. The system can supervise the running status and alarm when its works take place abnormality on line on the basis of GPRS network, ARM embedded-system and data-base design based on Lab Windows/CVI.
Keywords:Intelligent monitoring; GPRS;ARM ;construction machinery;
1. INTRODUCTION
The performance and quality of the construction machinery has a very important influence on the construction schedule. But construction machinery has a higher failure rate because of its complex structure, uncertain load and poor working environment[1]. Therefore, the supervision of the construction machinery’s performance is a sticking point for the stabilization, safety and reliability of construction work. With the social development and the advancement of technology, people have become increasingly demanding on the performance monitoring and fault diagnosis of construction machinery in order to get a higher efficiency and lower consumption of construction project. The new-generation construction machinery not only need integrating operation and intelligent control, but also need cooperating with the whole construction machinery group whose control system is based on network. At present, the traditional construction machinery which is only d
esigned by general electronic control techniques and its traditional regular maintenance can not meet the requirements. So a new construction machinery monitoring system, which can finish the local centralized control, supervision and maintenance, and can also carry out remote-distance monitor and diagnose, has become a hot research problem[2]-[5].
In order to supervise the running performance of the construction machinery, this paper proposes a construction machinery on line monitoring system which is based on general packet radio service GPRS network. This system can supervise some parameters such as speed, pressure and temperature of the construction machinery through the long-distance supervised terminal.
If the construction machinery’s maintenance person wants to know the running status of the construction machinery, he can sent a short message to the supervision cell of the system, and then the system sent the running parameter to the mobile telephone of the maintenance person or the monitoring center by GPRS
module through the communication network and Internet, so the real time supervision of the construction machinery is realized. This system can also setup the alarm boundary of some important parameters of the construction machinery, if the construction machinery appears abnormal, the system would sent the alarm information to the mobile telephone of the maintenance person or the monitoring center, so the trouble of the construction machinery can be fixed up immediately. In practice it shows the superiority of the system.
2. THE SYSTEM STRUCTURE
2.1 Intelligent monitoring system structure
The intelligent monitoring system mainly consists of 3 parts: site monitoring cell, GPRS, and intelligent monitoring center, as Shown in Figure 1. Site monitoring cell is
set up in each construction machinery. And it communicates with intelligent monitoring center through the GPRS wireless network. In addition, the system structure is a three-layer model. The site monitoring cell is the lower layer, focusing on the access of device status information. Intelligent monitoring center is the upper system, focusing on processing of status and fault information. Between the lower and the upper layer, GPRS finishes their communications.
GPRS network is a communication medium of the whole system, through which short message, voice, and tow kinds of packet data (IP and X.25) can be received and sent. Control terminal (mobile phone) is a remote controller and the display in the system, which is responsible for sending a variety of short command message (such as the command for monitoring the realtime status of construction machinery) and receive the short return message (such as the implementation of the short commands message, and the alarm information of fault).Intelligent monitoring center is responsible for receiving the data from site monitoring cell and managing a variety of information.
