| In order to enhance the electricity generation efficiency, the generator system uses the hydrogen to take the cooling agent. Though the hydrogen is one kind of high quality thermal conductivity cooling medium, it is one kind of flammable explosive gas, synthesize each parameter of hydrogen cooling agent in the processing of generator monitoring system is the essential condition of the guarantee to the security and the highly effective output of the electric power system. The GSM communication, proposed recent years ,is the new way may apply to the generator hydrogen parameter monitor. It has the merit of the number to pass on the broadcasting station communication way, does not have the limit of frequency application and the emissive power, and also does not need to build network, reduces the expense. Therefore selects the GSM to monitor the big-quantity and broad-surface hydrogen parameter of the generator automation , it's one economical reliable choice to the electric power department.The generator hydrogen parameter scene real-time monitoring system of this thesis researched, synthesizes the application of modern computer technology and the digital wireless migration communication technology, based on the measuring appliance of lower position machine, using the GSM network to carry on the data transfer, Communication protocol is defined between up-computer and down-computer,can real-time to realize the hydrogen parameter of generator scene's telemeter, remote control, movement breakdown warning and so on.This paper unifies the GSM network in the SMS communication way realization mechanism and the realization process, put emphasis on the introducing of the hardware party and the matters needing attention of the monitor-center and the monitor-stand, and how to use the Delphi language and C430 language to realize the overall system's receiving and dispatching short information and judging, classifying and so on. |
