| The article mainly introduces microcomputer communicationin electric drive system of modem AC, which is applied in aSwitched-Reluctance Drive (SRD). The system includes twosegments:remote operating board and primary computer.In the paper six parts are described. The first part widelydiscusses operating control mode of frequency inverter at homeand abroad now and outlines the structure and principle of SRD.Then the content of research is put forward. In the second part,through studying control mode of communication and protocolbetween microcomputers, the communication protocol is broughforward. The third part, comprehensive design of software andhardware is made to remote operating board and primary computer,then partial program codes, the circuit and flow chart of everymodule is introduced in detail. In part four, general debugging iscarried through and results in experiment are analyzed andsummarized. In the fifth part, through analyzing the source ofhampering, many measures that are taken against hampering arediscussed. In part six, the whole article is summed up and thefuture work is looked into. |
