奇偶校验位
- 网络parity bit;Parity check
-
完成无线传感器网络数据的接收。设置虚拟串口的波特率、停止位、数据位、奇偶校验位,对串口进行读写操作,实现了基站节点与网关节点之间的USB虚拟串口通信。
Receive data from wireless sensor network . Through setting baud rate , stop bits , word size and parity of virtual serial port , and then operating serial port with reading and writing to complete USB virtual serial communication between base station and gateway . 3 .

由于采用了中断方式和字符格式进行多机通信,解决了奇偶校验位与地址/数据位(TBS)间的矛盾、提高了系统的可靠性和实时性。
The contradiction between parity bit and address / data bit is solved as the interruption and character mode are used in the system . The reliability and the realizability of the multimachine system are both improved .

奇偶校验位加在二进制码上的一个标明奇偶数的位,用于检验数据的完整性
A bit added to a binary code that indicates parity and is used to check the integrity of data . even parity check
