| The mobile communication system just as GSM CDMA has developed quickly in recent several years, therefore the quantity of the equipment and base station has increased quickly. In order to make GSM and CDMA system working stablly, its power system and working envirment should be automatically supervised and controlled in the base station and mobile switch center.It is the current trend to use the remote embedded supervision system for the remote supervision and control. Using the computer, network and communication technology, the manager can mast the remote equipment running station and control the equipments with sensors installed in working site. The supervision system has good flexibility and expanded ability, hence the stability of mobile system has been improved .The data picked up by sencors has been transferred to the remote monitoring center with communication networks. Through processing data, the equipment status of the remote working site has been controlled. If some problems have happened, the supervision system will give an alarm and confirm the trouble equipment and inform the relevent people to deal with them with short message or dialing number.In this dissertation are discussed the remote supervision system of base station, the hardware of key module of the embedded base station supervision sub-system,.the framework of supervision system and the key technology , the bootloader designing and debugging detailly.Several valuable and important results which bring forth new ideas are achieved and listed as the following:(1)Use the embedded technology to the base station supervision system first time.(2)Base on the market requirement, we provided the E1 time slot switch, E1 special telephone line, orderwire wire communication channel, MODEM dial, short message and other wireless transmission channels.(3)Provide the network interface for the future 3G applications.(4)Use the embedded Linux operation system to the base station supervision system first time. |
