Based On The Internet Of Things Of Intelligent Build Information Integration Key Technology Research And Application

With the rapid development of society,the pace of social information is also accelerating.Information integration in high rise buildings,but also an indispensable part of social information.In the high rise building,the information integration can realize the effective management and the reasonable allocation of resources,and improve the office efficiency of the building.Now,most of the buildings of the information management is single,so there are a lot of drawbacks,one is not unified information management;second is not anxious to find fault and risk;the third is not information storage and information query.How to realize the organic integration of the information of high rise building,then becomes the primary challenge for the intelligent building researchers.The main source of this challenge is the amount of information that is very large.Such as electricity,water,gas,fire,security is very important in the construction of information.It's very difficult to integrate all the information.This system combines the technology project of Changchun City: the key technology research and application platform construction(12ZX56),which is based on the Internet of things.The realization of information integration function of high-rise building.This system takes the school teaching building and the experimental building as the research object,and the Zig Bee acquisition module is installed in the meter,water meter,gas meter and other measuring instruments.And then through the ZigBee wireless router,and then by the CAN bus to the gateway,the gateway is transmitted to the PC server,and through the Internet can query.The system also set up a database to store all the information for the user to use for three years,analysis,query.This system uses CC2530 chip as the core chip information collection terminal node.Through the wireless router CC2530,by the CAN bus system is transmitted to the Zig Bee gateway,and then by thehost computer management and storage.At the same time,the system also designed the automatic control system,when the system appears over voltage or under voltage,the automatic control system will automatically cut off the power supply to protect the entire system.When the water pipe suddenly burst,the water pressure sensor will collect the signal,then the automatic control system will sound and light alarm.The system also combines the fire protection system,temperature,according to the amount of collected information makes the fault alarm,exception alarm and fire alarm three different kinds of alarm.The system terminal acquisition module between the router and the data transmission using the Zig Bee wireless transmission,but in order to improve the accuracy of data transmission,between the router and the router,between routers and gateways,gateway between the host computer and the is can bus transmission.This combination of wireless transmission and cable transmission to solve the cost of the entire system also increased the accuracy of data transmission.This design in the wireless data transmission process,using the fuzzy algorithm for data transmission control,fuzzy algorithm constantly correcting the deviation of the wireless transmission process,to ensure the accuracy of data transmission.The research success of this system and the promotion will further improve the intelligent level of building wireless data building information integration.The successful development of the system will be of great practical significance to the further development of the Internet of things.Can be used in many fields of information integration,has a high practical value and development prospects.
