INTRODUCTIONThe performance and quality of the construction machinery has a very important influence on the construction schedule. But construction machinery has a highe

4、r 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 advancement

5、 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 i

6、ntelligent 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 meet

7、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 con

8、struction 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 supervise

9、d 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 moni

10、toring 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 abnorma

11、l, 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 sy

12、stem 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 wire

13、less 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 t

14、he 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

15、, 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 mon

16、itoring 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 evo

17、lved 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 main

18、ly 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 of

19、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 contro

20、l 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 m

21、achinery 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 parame

22、ters 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 mea

23、sured 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 e

24、quipment 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 the

25、 abnormity and also receive consultation orders from the intelligent monitoring center.2.3 Intelligent monitoring centerIntelligent monitoring center of the construction machinery is the core part of the whole system. It is responsible for receiving the system status information and alarm informatio

26、n from site monitoring cell, classifying and preserving the information. Intelligent monitoring center, on the one hand,carry through two-way communication through the GPRS network and terminals at the site , on the other hand, it provides users with a visual interface, and allows users understand t

27、he distant construction machinery at home. The intelligent monitoring center must depend on GPRS Wireless Modem to communicate terminal. Additionally, it is also responsible for completing fault diagnosis of construction machinery, including the specific status and fault information of the every con

28、struction machinery, and analysing to determine the cause of the malfunction.The system application software adopts modularization design. It is mainly divided into the following modules:Initialization module. It can load and initialize system parameters from the configuration file to ensure reliabl

29、e operation of the system. These parameters include the serial port parameters (such as the com port, baud rate, etc.), GPRS terminal parameters (such as the short message center number, etc.) and system parameters (such as inquired cycle of alarm information, log storage time, etc.). The module use

30、d in conjunction with the system setting. Its role is to set these parameters to make the system run better and save configuration files to the system for reinitialization.Automatically processing alarm information module. After the system initialization, system procedures have begun to implement. A

31、t the same time, automatically processing alarm information module has begun to run. It constantly reads alarm information from an external file into to alarm message queue, and sends the alarm information to the target group. Alarm information includes alarm content, alarm time, alarm source, targe

32、t group .etc.*Manually processing alarm information module .Sometimes, workmen on duty need to process alarm information according to the actual situation. In view of this, the system makes manually processing alarm information module. Workman can manually send alarm information to designated mobile

33、 phone.* Dat abase management module. The module can complete the maintenance of database information. Users can view, add, delete, modify and update database information.2.4 Intelligent monitoring centerThe system program includes 3 major components: communication part, databases part, and human-ma

34、chine interface part. Communication part can read data from sensors, and then save them through database, and display them by means of tables or curves throng human-machine interface. The system the design of flow program is shown as the Figure 3.3. DATABASE DESIGN BASED ON LAB WINDOWS/CVIIn the fie

35、ld of intelligent monitoring, with the increase of complexity and difficulty of integrated testing, more and more test parameter will be involved, including the tested object, test equipment , test result, test people, etc. Their maintenance and management will be achieved in a unified database.Lab

36、Windows / CVI can achieve access and maintenance among a variety of heterogeneous database. As shown in Figure 4. In the figure, Lab Windows/CVI can receive data from test parameters and save them to database. Then, it can also read the data from the database. In addition, it can finish graphical di

37、splay based on the read data.CVI SQL Toolkit is available to use CVI software package to operate the database, which includes a series of high-performance operation functions. The comprehensive application of these functions can realize multi-functional database. After SQL Packet installation, Lab W

38、indows /CVI SQL will be automatically registered an ODBC (Open Database Connectivity) data source on the machine, the data source is namely the data source used in the examples of Lab Windows / CVI SQL procedures. In order to achieve Lab Windows / CVI to access database and realize the data manageme

39、nt, the system uses the ActiveX Data Object (ADO) interface technology and ODBC (Open Database Connectivity) and select Microsoft's Access database and take SQL Toolkit as data management and software development tool.Because of the more test parameter of construction machinery, it is important

40、for user to design a good and clear interface of monitoring. Lab Windows / CVI can provides development environment to design a better interface based on the database.
