| Abstract: | The principle of the spread spectrum communication and the structure of the remote meter reading system are introduced in the paper. In allusion to the defect of big noise and signal attenuation, we put forward the idea of applying DPSK DSSS to the system and design the total scheme and then introduce the structure of PL2101 chip and its work in the system. At last, the design of software module is briefly introduced. The system presented in the paper provides high utility value and wide application foreground. |
