This article evaluates agricultural operator´s stress, mental strain and generally fighting with driving difficulties during operating agricultural machinery sets by means of a heart rate indicator. Different drivers driving different tractors with implements were chosen and evaluated during different field jobs, namely soil tillage and sowing. Machinery position on the field was precisely monitored by a GPS receiver and the heart beat rate was observed by means of a chest belt special device with a heart rate sensor. The output data from the sensors were monitored during conventional manual steering of the tractor-implement set and also when using the complete automatic guidance steering without any driver´s intervention to steering wheel – all by using the DGPS guidance signal. The data were further processed with a special software for the heart rate sensor and detailed statistical evaluation was performed. All described trials were measured at different farms in the Czech Republic. The final outcomes from the experiment showed a statistically significant difference between two experimental variants and confirm our hypothesis that the guidance systems bring a great benefit for drivers concerning mental strain and relief of their workload.

The network communication between MATLAB and configuration software is established using DDE(Dynamic Data Exchange) technology, which is easily to give full play to generate interactive interface in configuration software and simulation of control object model in MATLAB software. The calculation function of weakness in configuration software is repaired and the control object model and controller is to be isolated. The effective simulation platform for theory research and design of control system is established.

Central Control System

Monitoring system for transformation and distribution equipments plays an important role in offshore platform safety production. This paper introduces the OPC technology and discusses the requirements and architecture of this monitoring system. For the convenience of monitoring data exchange, OPC technology is applied in the design and realization of the monitoring system. An OPC server is created for the monitoring data publication, and the monitoring system can get cable load current data from the OPC server in the central control system. In this way,the monitoring system can exchange monitoring data with the central control system more efficiently.

After analysis of the mill head magazine, the attachment to the movable beam type machining center XH2125/H-800, which is of SIEMENS840D numerical control system, is developed in this paper, the software contains automatic exchange of mill head function controls. This software compromises the functions of the user variables and the high-level programming language, and is based on the data exchange and data comparison between CNC and PLC. All mill heads locates in the magazine that can distinguish, search and exchange automatically, and this system can display the suggestive information or failure warning safeguard in time on the operation screen to make it easy for user to operate.

ABSTRACTA versatile control system, which uses standard commercial software and hardware has been developed and applied to control oxide (and carbide) MOCVD and CVD systems. The control system is implemented within a personal computer platform. The system operates in the real time Microsoft WindowsTM environment utilizing the full advantage of the sophisticated graphical user interfaces, dynamic data exchange, networking, and multitasking capabilities. We have used two different sets of commercial software to control and monitor system hardware. The first software set is INTOUCHTM, a Man-Machine interface software from WONDERWARETM in conjunction with Microsoft ExcelTM and I/O interface software. The second software set is LABVIEWTM, which is primarily a data acquisition control system from National Instruments, combined with Visual BasicTM. Both systems include a friendly interactive real-time windows-based user interface, an advanced process entry and recording spread sheet interface, alarm and security management systems, data display and recording, maintenance routines, and complete networking and remote operation capabilities. In addition, the configurations provide a flexible hardware interface that can directly interface to I/O cards in the PC's bus, as well as to most industrial Programmable Logic Controllers, various types of process controllers, I/O devices and other forms of hardware. Most importantly, the system can interface with any in-situ process monitor or higher level intelligent process control systems in order to optimize the process. Modules may be activated or deactivated as needed (even as part of the process). These systems have been used for home-built systems, as well as to retrofit a modified Spire SPI-MOCVDTM 500XT system. General process interaction and results will be discussed.
