Design of Minitype Measuring and Control Network Based on UART

The paper introduces a kind of minitype measuring and control network,it is made up of the UART resource of PC and single chip.The network realizes a method for serial communication between singlemaster and multislave,and it hold out plug and play.The system structure is very flexible and its expansibility is better.The master can convenient to visit any slave,and the twoway transmission of the data(8 B or less than 8 B every time) between the master and the slave is realized.Through the specific application,it proves that the network is reliability and stability.
