Research On The System Of LAN Remote Mobile Control

For wired communication of the wiring is installation of complex,Time-consuming, expensive high, limited transmission distance, not easy to modifyand difficult to expandand other defects. The issues from the perspective of intelligenthome control, proposed using the2.4GHz of nRF24L01for the band radio frequencytechnology and GPRS/GSM mobile communication technology to build a local areanetwork control program. using single chip microcomputer as the microprocessor, therealization of data sent and received instruction via remote mobile terminal.To meet the stable transmission for remoting mobile terminal data as well asachieving effective control of electrical equipment, The system presents theassociated hardware circuit and firmware.The followings are the main contents:(1) To research the related of LAN technology, mobile communicationtechnology and the remote mobile terminal technology, We’d better select the highcost Performance of mobile communication module and the wireless node module todesign. At the same time, with the help of mobile phone and computer to achieve theremote control of electrical devices through wireless communication.(2) The system design of hardware circuit. Mainly including the hardware designof remote mobile communication controller and wireless node controller. Use thedesign concept of modular, the integration of the WSIMO228communicationmodule、nRF24L01wireless communication module、serial communication modules、human-computer switching module and others for remote mobile communicationscontroller. Wireless node controller include non-isolated power conversion module、nRF24L01wireless communication module and relay control module.(3) The system design of firmware. Curing the microcontroller program mainlyconsists of the WISMO228mobile communication control procedures、nRF24L01wireless nodes control procedures、LCD procedures and key processes and othercomponents.(4) Combined with the system application software, to test the related LANremote mobile control system of hardware and software. To achieve the remotemobile terminal electrical equipment control.The subjects from improving remote mobile with the needs of real-time performance and practicability of the control system, build a home network.Designing a smart home remote control system based on wireless LAN technology,basically meet the operational requirements of home appliances, smart phones can beachieved the appliance monitoring by the user. The system with high stability, highreliability, simple operation, low power, low cost, easy to expand and othercharacteristics, and has good practical value.
