| Abstract: | SMS (short message service) terminal is used for industry remote control. For the application,the frame of system and principle of work are given. How to encode the message in PDU mode and decode the message from PDU is the technical difficulty in SMS terminal developing. Several solutions are given. New delaying function is raised to solve the problem cause by the normal sleeping function during the waiting for replay of modem. The SMS receive/send flow under the control of AT order,including the relative algo-rithm code are also given. |
