Development And Application Based On Dual CPU Configurale Of The GPS Module And GSM Module

It is of great significance to transmission the information and remote control by SMS with GSM module based on the GSM Net which covers the whole country in industry domain, agriculture domain and traffic domain .In the article, use two pieces of singlechip and one ferroelectric memorizer(FM25040) to compose a control module with dual serial port. One serial port is to control the GSM module, the other is to receive various digits according to different applied domains . The paper mainly concerns the research which we do into the GPS navigation system. The GPS navigation system is in ascendant at present .The work process is as follows,Use one piece of singlechip to simulate the GPS receiver, and then send the navigation information through TXD end to serial port which is under the control of dual CPU module. The CPU1 of the dual CPU module receives the navigation information and compress, then sends it to FM25040 where it would be stored after checking and comparing with the information sent by the control center. The CPU2 of the dual CPU control module first checks and deals with the new command sent by the control center, then reads out the navigation information stored in FM25040 and sends it to the control center through the GSM module. The control center receives the navigation information through another GSM module; and screens on the computer. At control center, the debug software is the super terminal with the...
