LabVIEW is a graphic programming language and widely used in measurement and control systems, but it don't have the ability of formal verification, this may cause potential hazards of conflict, collision and deadlock in large and complex measurement systems. This paper uses Petri net to model and analyse measurement and control system, then mappes it into LabVIEW. The two graphic languages are easy...
Aiming at the online fault diagnoses of the power cable, an online Power Cable Monitoring system is built by using the virtual instrument platform Lab VIEW. In the system, the monitoring surface is designed by using the graphical programming language, and the data acquisition card PCI6221 is used to capture the data and to monitor the state of the online cable. The experiment shows that the functions...
Base on analysis of influence factor about strip's convexity degree and transverse thickness, established online monitoring system of cold rolling strip's thickness and convexity degree, to emulate by application of LabVIEW software, and compare with the practical situation, as result of it could mainly meet requirement of online virtual monitoring.
The remote monitoring system of mine safety based on C/S and B/S mixed mode was developed by using the virtual instrument technology, network technology and database technology. The system consists of sensors,the underground substation, the ground monitoring center remote clients, through internet explorer, the remote client can browse the real-time monitoring data of mine safety, such as gas, wind...
This paper presents the design of a multi-channel distributed monitoring platform, which is highly suitable to be applied into a traction supply system for urban railway transportation. In our platform are combined the technologies of Ethernet and virtual instrument, fully exerting their merits of large data capacity, high efficiency and low cost. With a HMI (Human Machine Interface) and a VO (Virtual...
Based on the design concept of virtual instrument and the design method of function modulation, using PC machine and data acquisition card as hardware system, proposed a design of sewage multi-parameter online monitoring system which based on application program platform of Lab VIEW. The system has friendly human-machine interface, the function is comprehensive and it is easy to operate. It has achieved...
The basic knowledge of virtual reality and virtual instrument technique were introduced. According to the present safety conditions of foundation excavation, the support monitoring system of foundation excavation is put forward. With Windows and Lab VIEW technologies, the support monitoring system of foundation excavation is developed, which is integrated with data automatically collecting, information...
The application of advanced virtual instrument development platform LabVIEW, with hydraulic test bench and sensors, developed a hydraulic monitoring system based on LabVIEW. Introduced the system's hardware and software design, and realized measurement and display of the pressure, flux, temperature, displacement, velocity and acceleration in hydraulic system, and the alarm of system failures, storage,...
