Based on “MCU+CPLD Architecture” to design beacon tranmitter
Abstract
Beacon transmitter is an important device to the unication and navigation in airport,so it's of great strategic value to make applied researches.
This paper's name is baseed on "MCU+CPLD Architecture" to design beacon transmitter. this thess points out some disadvantages of device ,such as technology backward in technique and type ponents obsolete,manual operations,many ponents,very large size and weight,operating and maintaining diffculty. In order to small size and modules and standardization ,and improve the device's intergrated and very high enough realiability ,intelligence, I explored the method
of beacon transmitter's designing based on "MCU+CPLD Architecture",according to MCU,ponents applied to the many instrument and device.
The major work of this dissertation is as follows.
1. Analysising the feature of MCU,CPLD, FPGA, I provided the method of beacon transmitter basee on "MCU+CPLD Architecture".
2. Audio signal frequency is implemented in CPLD,give the schematic of the designing.
3. Decording,latching data controlling signals are implemented in CPLD by interface between MCU and CPLD.
4. Beacon transmitter's designing.
S. Drawing the flow chart and making the MCU controlling and monitered programe.
This paper introduced the method of the beacon transmitter, and gived the advantage tastes bymaking beacon transmitter very sma
