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.

Pandemics, climate warming, growing inequality, and much more bring crises that change the patterns of daily life in human communities, directly impacting the provisioning systems that form in a community to meet the needs and wants of individuals, groups, and entities for goods, services, experiences, ideas. Provisioning systems sometimes begin as leadership initiated top-down, authoritarian prescriptive supply networks, public and private. Sometimes, they originate as bottom-up, self-organized, innovative, open choice, often informal, exchange based networks, and mostly, over time, they emerge as untidy self-organized multi-level diverse assemblages of both. The diversity of provisioning systems in a community enables crisis resilience, but limits efficiency and control. The provisioning systems that form in these ways are complex, multi-level, non-linear evolutionary systems, often unpredictable, and lacking direction. Balancing a desire for stability and an appetite for diversity, innovation, and change in shaping a provisioning system is like walking a narrow corridor on the edge of chaos. Achieving balance, avoiding slipping into chaos, rests on the management of a set of complex social mechanisms. These embrace delivery mechanisms where value is produced and consumed through complex infrastructures; stakeholder action fields where trust, collaboration, cooperation, compromise, competition, or conflict are in play; technology evolution mechanisms where innovation and the recombination of existing technologies occur at all levels; and value exchange fields where community and individual values shift in response to crisis and change. Recovery from crisis is not an event, it is a complex, continuing process, often unpredictable, often unequal in outcomes, but walking a narrow corridor is episodic, uncertain and in the end possible. This is the next normal for marketing.
