This paper is about the research on the industrial Ethernet communication between industrial PC (IPC) for a spinning machine and OMRON programmable logic controller (PLC) based on FINS protocol and Winsock in VC++. This proposed networked communication has been successfully designed, installed, commissioned and realized. This paper focused on reliable real-time communication transmission and integrated...
According to requirements, a solution of remote PLC experiment system has been introduced, including total architecture, hardware and software design. We made a remote experiment in order to control simple mechanical equipment with S7–200 PLC. Then through CP243-1IT, mechanism, PLC, server and clients from internet are mutually connected. By visiting lab web and operating panel of console interface,...
This article puts forward a method to access the data and analyzed results from the monitoring system of environment based on WSN with the B/S mode. It resolves the problem of low speed of page refresh with Ajax. The experiment shows that the partial refresh feature of Ajax can make it possible for the users to get access to the data and analyzed results easily through the browser, and experience...
Ship dynamic and video monitoring system at sea aims at improving safety of ship sailing and providing help for salvage. In this system, wireless communication technology of CDMA1X is used to transfer GPS dynamic positioning information and ship video. As to the special communications at sea, the actual bandwidth of single channel CDMA1X is too low to transfer video. In order to cope with this problem,...
The turbo-generator unit is very important equipments for electric power production, which has a high rate of fault and causes a lot of harm because of the structural complexity and the special circumstance. With the increasing of the capacity of the unit, the condition monitoring and fault diagnosis plays an important role to ensure safe operation and guarantee the efficiency. Therefore, the real-time...
