Research Of Network Safe-guard Information Collection System In Intelligent District

In recent years,with the continuous social progress and development,increasing people's standard of living and way of life has also undergone great change.People have been pursuing safer,more comfortable and more intelligent home as their goals.Intelligent home network system takes modern computer technology,communication technology and control technology as foundation. The kernel of smart is the control system which is used to process the control policies,and give a friendly interface to users.It can receive signals from sensors,generate commands based on demands,and send them to executors,thus achieves home intelligence.This article discusses one intelligent district monitoring system,based on CAN-bus and LPC2290,which can be used to achieve solid concise communication between the monitoring equipments and field devices,to complete real-time measurement and control of large,scale equipment.Firstly,studying on CAN-bus technology, the hardware of CAN node module based on the 8-bit microprocessor and the intelligent home controller based on the LPC2290 are designed.This intelligent system also uses wireless transmission technical means, overcomes the shortcomings of cable transmission technology, achieves the receiving and dispatching the home warning information ,selective control of household appliances.Then,transplant ofμC/OS-Ⅱoperating system in LPC2290,as well design and implementation of the application software of interconnection system,that is discussed. Lastly, modules of the system are tested. Test results show that the system meets the performance targets.The system can provide a more safe, comfortable, convenient, fast and open living space which is intelligent and information-based for the residents.
