INTRODUCTIONThe performance and quality of the construction machinery has a very important influence on the construction schedule. But construction machinery has a hig
4、her failure rate because of its complex structure, uncertain load and poor working environment1. Therefore, the supervision of the construction machinerys performance is a sticking point for the stabilization, safety and reliability of construction work. With the social development and the advanceme
5、nt 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
6、 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 designed by general electronic control techniques and its traditional regular maintenance can not mee
7、t 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 problem2-5.In order to supervise the running performance of the c
8、onstruction 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 supervi
9、sed terminal.If the construction machinerys 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 mo
10、nitoring 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 abnor
11、mal, 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 STRUCTURE2.1 Intelligent monitoring
12、system structureThe 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 wi
13、reless 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
14、 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 syst
15、em, 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 m
16、onitoring center is responsible for receiving the data from site monitoring cell and managing a variety of information.2.2 Site monitoring cell structure based on ARM embedded systemSite monitoring cell is designed and developed by the ARM MCU and its auxiliary equipments. The ARM architecture has e
17、volved to a point where it supports implementations across a wide spectrum of performance points. The architectural simplicity of ARM processors has traditionally led to very small implementations, and small implementations allow devices with very low power consumption.Site monitoring cell can be ma
18、inly divided into five units in accordance with their functions: data acquisition unit, communication unit, Single-chip (EasyARM615) unit LED display unit, and power supply unit etc, as shown in figure 2In the figure, data acquisition unit is mainly responsible of collecting some important signals o
19、f construction machinery, such as water temperature, work pressure, and speed etc. Communication unit with GPRS network is mainly responsible for communications and data transmission. LED display unit is responsible for the current status of construction machinery. Single-chip unit which is the cont
20、rol core of system is responsible for coordinating the normal work of the various parts in system. Power supply unit is responsible for providing required voltage.Because nearly all the supervised parameters will be attained from site monitoring cell, it is the base of the whole system. Construction
21、 machinery is made up of the power system, engine, steering system, transmission system, brake system and electrical system etc. In the each relevant system, the sensor will be set up. From the sensor ,the corresponding parameters can be obtained. Site monitoring cell can read the corresponding para
22、meters from sensor, and monitor them in real time.So the parameters choice is important for site monitoring cell. In theory, the more monitoring parameters is obtained, the better effect is gotten. But in fact, it is impossible considering cost and operation. Furthermore some parameters can not be m
23、easured in practice, such as engines emission, transmissions screams and operating efficiency decrease. The phenomena are more difficult to monitor by sensors. But they can be intuitively perceived in time by operators, so the system should make full use of the site operators estimation as a sign of
24、 equipment failure analysis. For the reason, site monitoring cell use the methods combining sensors measurement with operators sensing to obtain parameters information, and provided the information to the Intelligent Monitoring Center. Additionally, site monitoring cell must have alarm function in t
