Online monitoring and controlling system for printing machine is developed based on ZigBee technology and MCGS with some advantages of real-time, reliability, wireless character etc.. The article discussed the technical characteristics, network topology structures and application prospects of ZigBee. And then a scheme on wireless monitoring and controlling system for printing and dyeing machine system...
Zigbee is a kind of short distance wireless communications technology. The article discussed the technical characteristics, network topology structures and application prospects of ZigBee. And then a scheme on wireless temperature monitoring system based on ZigBee was proposed. The system adopted Star topology structure CC2430 chip of Chipcon Company and 18B20 temperature sensor of MAXIM Company....
In order to detect the moisture content of fabric quickly and accurately, an on-line measurement system based on microwave transmission principle was designed for measuring moisture content of fabric,which achieve the moisture content of the fabric on-line non-destructive testing. Focused on the measurement principle and method, using least square method fitting a straight line to obtain calibration...
In view of the deficiency of most of programming tool in connecting a professional database and manipulating data difficultly, a method is applied to realize the exchange visits between LabVIEW and database, and actualized the exchange visits. Tested by experimentation, the method can provide both students and administrators with an easy to learn, easy to use system that, through automation and web...
With the development of the wireless technology, ZigBee is paid more attention to in many aspects of industry automation, social communication, smart home and so on. The purpose of this article is to analyze some definitive descriptions of NWK layer of the ZigBee protocol stack, and to realize some basic applications. Through descriptions and some applications, the article analyzed and verified ZigBee...
In view of the degree of the information is not high, the formation of the various parts as a system of “information islands” and other issues in printing and dyeing industry, this paper studied a control system for rotary screen printing machine multi-axis coordinated motion control as the core based on CAN bus, to enhance the multi-axis synergistic motion accuracy as the goal. A study from the following...
The communications and control of PLC in industrial site usually adopt fieldbus technology such as the CAN bus. In PLC communication, the process is that monitor PC sends some simple communication codes to PLC and then some PLC feedback status are transmitted to monitor PC through bus. When the quantity of data transmitted is not large, PLC's data communications can adopt ZigBee technology. On the...
