Design And Implementation Of Monitor And Dispatch System For Jiayuan Hotel

With the continuous development of urbanization in China,the number of buildings is increasing.The security and management affairs in buildings are becoming more complex and diversified.Jiayuan Hotel is a comprehensive star-rated hotel with catering,accommodation and entertainment.As the customers staying at Jiayuan Hotel are increasing,the demand that Jiayuan Hotel's staff deal with the unexpected situation is urgent.Based on WLAN(Wireless Local Area Networks),Jiayuan Hotel monitor and dipatch system has functions such as video surveillance,voice call,video call,text transmission,and dispatching station.It can enable the managers to monitor emergencies accurately and conduct relevant people to handle it effectively to ensure the safety of the customers' life and property.Therefore,the design and implementation of Jiayuan Hotel's monitor and dispatch system has important practical value.Based on the review of the current research situation of monitor and dispatch system,this paper designs and implements Jiayuan Hotel's monitor and dispatch system.The main work can be listed as follows:1.According to the current situation of Jiayuan Hotel's monitor system and dispatch system,the paper analyzes the coverage,the functional requirements and the performance requirements of Jiayuan Hotel's monitor and dispatch system.Then it gives the composition of the monitor and dispatch system of Jiayuan Hotel;2.By comparing the usual WLAN handoff technology,the method of roaming navigation is used to change the power of the AP(access point)dynamically to send management packets,so that the terminal initiates the handover actively.The method solves the delay problem of the terninal when move between near APs;3.The overall structure of Jiayuan Hotel's monitor and dispatch system is designed,and the selection schemes of monitor system and dispatch system equipment are given respectively.According to the calculation of the lens focal length and the visible distance,the deployment plan of the monitor system monitor point is determined;The AP channel frequency configuration is planned,and the AP deployment plan of the command and dispatch system is determined according to the calculation of the indoor and outdoor AP coverage.The monitor system realizes the functions such as video playback,screen switching,snapshot capture,video save,face sign-on,etc.The command and dispatch system can realize the functions such as single call,group call,video,text transmission,picture transmission,and dispatching station etc.4.Functional testing and performance testing of Jiayuan Hotel monitor and dispatch system are done by using Secure CRT and Wi-Fi Inspector analyzer.It's performance and functions can meet the overall design requirements of Jiayuan Hotel's monitor and dispatch system,it can also meet the need of the hotel's security and management.
