The GSM control module configuration software of installing on the described computer carries out following configuration to the GSM control module:

(1) serial line interface that communicates between GSM control module and the computer is set;

(2) the remote controlling mobile phone number that can carry out to control relay one～four Long-distance Control is set;

(3) remote control commands that control relay one～four is controlled is set, comprises that instruction password, remote controlling mobile phone are with the control relay open command of note transmission, the control relay shutdown command that remote controlling mobile phone sends with note, message reply order and the relay actuation time that feeds back to remote controlling mobile phone;

The remote control commands that described antenna reception sends to remote controlling mobile phone feeds back signal to single-chip microcomputer after by GSM signal processing module processing and identification, single-chip microcomputer sends switching signal to control relay and indicator light, the switch of control relay control main relay, the action of main relay control switch main body motor drive mechanism.

Described serial line interface is the RS232 interface.

Described remote controlling mobile phone number is 1～3.

The field control signal that field apparatus sends links to each other with the control relay wiring that is connected to described main relay group.

The present invention is integrated in double power supply automatic transfer switch with gsm module, based on the gsm wireless communication network, switching operation with SMS or mobile phone communication Long-distance Control double power supply automatic transfer switch, and short message content and phone number can arrange by the computer that the gsm module configuration software is housed and change, operate very easyly, operating efficiency improves greatly.
