Test Study On Property Of The Parallel Composite Isolation Bearings

In order to adapt to the modern, large-scale building fire evacuation instructionsrequirements, development of an intelligent emergency lighting system to meet thesafety requirements of the modern buildings is necessity, the system can not only hasintelligent early warning before the fire broke out,but also can intelligent self-controland manual control, simplify the inspection and testing of the emergency lightingsystem.Through the study of the subject, an intelligent emergency lighting system basedon ZigBee technology is designed. The hardware part of the whole system by threeparts,collecting node (the coordinator node), router nodes and emergency lighting(terminal nodes).Coordinator node is responsible for collecting network theemergency lights nodes collected information and sends commands from hostcomputer to the corresponding emergency lights nodes in network. Router node isresponsible for forwarding packets between the coordinator node and emergencylighting node, TSL2561light sensor+CC2430chip the+DS18b20temperaturesensor chip as the emergency lights nodes’ core, responsible for the acquisition of thenode internal state information as well as external illumination, temperature and otherinformation, and sends a coordinator node.The system through internal emergency lighting implanted wireless sensornetwork chip CC2430, the emergency lighting in the traditional emergency lightingsystem is able to join the self-organizing wireless network coordinator node, byimplantation temperature acquisition and light collection, etc.The sensor chip is ableto collect so that each node of emergency lighting and ambient parameters. PCsoftware is capable of real-time detection system parameter information and thesurrounding environment of the emergency lighting node fire danger situation, the fireearly warning. The system will effectively solve the issues in traditional emergencylighting system, such as short use life in emergency lighting, and not easy toartificially control system functions more single etc(only lighting, not fire warningfunction), to meet the modern emergency lighting system’s requirements.
