Abstract:KingView software was used to design airport Ground Power Unit (GPU) metering equipment's host computer fault monitoring system.All data collected by lower computer were stored in SQLite database.The data were transferred to the host computer fault monitoring system's SQL Server database through the network.The Siemens GSM TC35 was implemented to communicate with the host computer fault monitoring system through the RS-232 serial port.Alarm will be sent right away by the fault monitoring system,when metering equipment is out of order or field service personnel mishandled the operation rules in the process of using the GPU providing power to aircraft.At the same time,the alarm information is sent to the relevant staff by e-mail and Short Message Service (SMS),and the SMS are issued by TC35 module which is connected to the host computer.
