Design Of Hotel Room Equipment Wireless Monitoring System

With the rapid development of China’s socio-economic, requirements of thehotels industry is higher and higher. But indoor control equipment of most majorhotels still remain in the stage of fixing switch on wall, and neither it’s inconveniencefor guest, nor the renovation cost is relatively high. In this context, the indoorwireless intelligent monitoring system has become very necessary, and wirelessmonitoring system designed equipment of the hotel room is an intelligent controlsystem which can meet the functional requirements.The design of wireless equipment monitoring system in the hotel room aimed atcompleting a set of system which can wireless intelligent control the hotel roomequipment. The system mainly consists of the master module, the wirelesstransceiver module, and charged with the module. Master module can complete thecentral control function of the hand-held side to the system; wireless transceivermodule is responsible for the information transform between the host and guest;guest module control several of equipment in the rooms under the control instructionof host, and monitor work status of equipment. Consider for the cost anddevelopment cycle, the host set up with the MSP430minimum system, the wirelesstransceiver module by the NRF905RF control chip. Host module is responsible forroom lighting, air conditioning, curtains, exhaust fans, electronic locks, fire alarmsand other devices controlled. Host module not only can be controlled by humancontrol, but also for intelligent control based on the actual environment.According to the requirement of system, selected a suitable design, designed themaster module, the schematic and PCB of wireless transceiver module and the hostmodule, write the control and communication program of the corresponding module,achieving the function that all host module can intelligently controlled by maincontrol module and the automatic control of the charged module according to theenvironmental parameters.This design carry the actual functional testing during the commissioning phase, the obtained experimental results confirmed that the choice of this program isfeasible and reasonable.
