图 8为本发明交换机与终端间进行数据传送的流程图。 实施本发明的方式 为使本发明的目的、 技术方案和优点更加清楚, 下面结合附图对本 发明作进一步的详细描述。
如图 3所示,在交换机与终端间基于双向 FSK方式的数据传送方式 下, FSK信号的逻辑 1的频率为 1200Hz土 1 % ;逻辑 0的频率为 2200Hz ± 1 % ; 波特率为 1200Baud ± 1.2 %。 调制方式采用连续相位二进制移频 键控, 数据传送方式为二进制异步串行方式。
如图 4所示, FSK数据字节的组成和发送顺序应满足下列要求: 每 一个数据字节应有一个起始位' Ό"和一个停止位 "1"。
数据字节的传送顺序是: 起始位先行, 然后是 .FSK数据位, 最后是 停止位。 FSK数据根据字节顺序传送, 即首先是字节 1, 然后是字节 2, 以此类推, 发送的数据信号是连续的。
在基于双向 FSK方式的数据传送过程中采用的 FSK数据包格式如 表 1所示:
Figure imgf000007_0001
1、 同步引导串
同步引导串由两部分组成, 第一部分是由一组 80个连续的 "0" 和 "1" 的交替位组成(先发 0后发 1, 总个数 80 ), 第二部分是由 40个 连续的 "Γ 构成同步结束串; 接收方读到至少 50个 "0" 和 "1" 的交 替位以及至少连续 20个 "1" 作为同步结束串后, 可认为同步建立。
2、 信息类型
指明信息内容的类型, 信息类型域长度为 1个字节, 具体内容如表 2所示:
Figure imgf000007_0002
表 2
3、 信息长度
信息长度指的是信息序列号的字节数加消息层信息内容的字节数, 信息长度域长度为 1个字节。
4、 信息序列号
信息序列号指当前 FSK数据包的序列号,序列号从 0x00开始编号, 信息序列号域长度为 1个字节。
5、 消息层信息内容
消息层信息内容采取 ASCII编码格式。 例如 , 交换机需要传送用户 通话费用 "2.30"元至终端, 则需要将其编码成 "0x32 0x2E 0x33 0x30" , 终端收到该数据后, 便于直接将通话费用显示于用户查看。 利用该种编 码格式, 可以满足现有所有业务的数据编码要求。 用于数据传送过程中的侦错, 取值为: 数据包中除同步引导串之外 的所有字节的和, 按 256取模再取补得到的值。 检验和域长度为 1个字 节。
我们还是以交换机传送 100字节的内容至终端, 终端返回 100字节 的数据至交换机为例, 不考虑附加信息内容所花费的时间, 可以计算出 需要耗费的总时长为 200/150 = 1.3秒(实际运用中考虑同步引导串等附 加信息内容, 需要耗费的时长大约为 3秒), 这与现有技术一与技术二 相比,数据的传送速度得到了相当大的提高,表 3给出了双向 FSK方式 传送数据的实验室数据:
