| The repeater is an important part of the wireless network systems.It can be used for covering the areas where the signals of base station is very weak,enlarging and strengthening the cover range and network intensity.The covering quality of the wireless network mainly depends on the application of monitor system,which collects the runtime data of the repeater.So it is realistic and practical to make a research on the monitor system of the repeater.According to the business characteristics of the construction of the repeater in our country,large numbers of the monitoring stations are scattered here and there in remote areas and there's no wire for telecom transmission.As the application and development of public wireless telecom technology,this essay contrives a scheme,which is based on collecting GSM short message business,to illustrate the remote wireless data collecting,namely,it attains the telecontrol of network management parameters.The most outstanding advantage is the low cost in basic construction,equipment,the operating of the system and the attention running.This research project is based on the analysis of GSM short message transmission principles;mainly solve the long-distance wireless data transmition problem of the running system of repeater.Finally,the collection and transition of monitoring data can be finished automatically, which is the reliable basis of the optimization and normal running of the repeater.And finally it achieves the automatic collecting and transmitting of the data,provides reliable basis for its optimization and running normally:1,The communication between the host and short message module in the monitoring center.Based on the short message module,the monitoring center can communicate with the principal computers.And then the runtime data can be received,the orders can be sent out2,The single chip microcomputer controls the SMS module to receive and send messages.It's the single chip microcomputer who collects and transmits the data to the short message module in position machine,and receives the orders from the monitoring center.3,The on-the-spot collecting system.The single chip microcomputer can be used to collect the data of electric pressure and transmitting power, store the data into the memory area in certain format,which then could be transferred when necessary.4,The design of monitoring software.It provides simple visual interface, which reflects the process of the system,and give the convenient to the operators. |
