The Design Of Smart Window Opener And Networking

With the development of science and technology,more and more high buildings and large venues,such as railway stations,large stadiums and factories appear in the society.Generally,these buildings have a lot of windows which are very high,and it is very inconvenient and unsafe if we close or open it by hand.The intelligent window controller system which is used as an independent terminal module can solve this problem well.In the meantime,the complete hardware and software protection measures in the intelligent window controller system,can avoid the windows controller and windows being damaged effectively.In addition,this system can manage all windows which in the building through the network,and it can be used as the executing agency of other devices to help achieve the system functions.The natural gas alarm window-opener system,which is the important system in the safety of the family,can make response measure timely to reduce hidden danger by checking the leakage of combustible gas(including gas,natural gas and liquefied petroleum gas)in the family.The system includes four parts: Sensor module,Central control module,Execution module and the Standby battery module.The function of the Sensor module is to detect the gases in the air,and outputs a signal to the Central module.The Central control module receives the signal from Sensor module,and transmits the command signal to the Execution module.The Execution module includes Intelligent window controller module and Manipulator module.The Standby battery module is designed to ensure the whole system can work normally in the case of power outrage.In the next few years,Smart home industry will develop rapidly,and this natural gas alarm window-opener,which is a subsystem of the Smart home system,shoulders the tasks of detecting combustible gas leakage and making response timely,and it is bound to play an increasingly important role in people's lives.In order to use the system more conveniently,the Remote control receiving module is added to the natural gas alarm window-opener system.And then users can control the system by the remote control.Meanwhile,in order to achieve control windows machine by network,the design use the RS-485 bus control mode.Through the Central controller,the system can control multiple windows system,and control all windows in the building overall.The maximum distance of RS-485 bus is about 1.2km,and it supports a limit number of nodes.However,those features of RS-485 bus are not suitable for the network of long distance or in large factories.The method to solve this problem is using TI's CC1310 chip for networking based on the Natural gas alarm window-opener system.In this network,every device is a node in the system,in other words,every device has its own unique address,and sends the information to the device through the wireless communication way.Then,the communication of the whole network will be more stable in the platform of SYS/BIOS operating system.In the Natural gas alarm window-opener system,the Central control module,intelligent window controller module,the Network nodes and the Concentrator.The C language is used to design the function of each module.In the wireless networking through CC1310,we completed the multiple tasks of writing for the whole system equipment in the application layer.And through the way of “Listen before Talk”,the system avoids the interference problem of same frequency between multiple nodes in the internet.At present,the natural gas alarm window-opener system has been used in family life,and the function of prevent leakage of the combustible gas is very practical.The intelligent window controller system which through the SYS/BIOS system to complete networking function have debugged,and the designed function has been basically achieved,Finally,if this system can be used in large buildings and factories,it can provide great convenience and security for users.
