The design uses 32 ARM processor S3C44B0X and Spartan™ -3E500 FPGA chip produced by Xinlinx company for setting up the hardware platform, and integrates the camera, GPS module, MiniGUI interface module. And realized bus vehicle mounted multimedia transmission control network control based on MOST. All of these are in the purpose of achieving a Predigest Project of vehicle-bone multimedia transmission and control network based on FPGA. The experiment indicated that, the transmission and control network system constructed by S3C44B0X and Spartan - 3E500 FPGA is low cast, simple and reliable.

Using advantages of PLC, SCADA, inverter, bus and internet in industrial production, in order to cope with the characteristics of large number of motor, complex sequential logical, high drive control demanding and distributed in different territory, it designs a configuration monitoring system for motor group integrative management and control network system, which uses PPI protocol and USS protocol and fieldbus technology, configuration monitoring technology and network technology, etc. It can realize the effective management of large number of motor driving and control. Due to its function quite similar, S7-200 and S7-300 and MM440 in the paper can be replaced by other kinds of PLC and inverter on the market. So the control scheme proposed by this paper is more practical and universal. Application in textile printing and dyeing institutions multi-cell motor driving, it shows that the designed system can drive and control the motor group with high efficiency and reliable.Keyword:largenumberofmotor;motorgroupnetwork;driveandcontrol;inverter;PLC-SCADA.

The article presents special characteristics of mathematical modeling of the process control a resource efficient heat supply system of industrial buildings and facilities, where constant temperature maintenance is especially critical for the process. A functional diagram of the operation of the continuous heat supply process is provided. The dependence of temperature at the point of heat-transfer fluid mixing on environmental is analyzed and control system operation algorithm is proposed.
