奇偶校验位

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

结合MCS&96系列单片机的通讯方式2、3，灵活运用通讯帧中的第九位数据位，即奇偶校验位，即可实现PC机和多台单片机的高效、准确的串行通讯。

Considering the communication model 2 and 3 of MCS-96 , serial communication between one Personal Computer and several singlechips can be realized by the use of the NO.

用户可选择波特率、奇偶校验、数据位等通信格式，适应采集系统不同的串行通信要求。

People can select Baud Rate , Parity Check , Data bits and Stop bits to match with the diverse communication requirements . 3 .
