摘　　要：井下式海底CPT系统中的数据采集与通讯是技术研发中的一个重要环节,针对通讯系统中触探数据采集与设备测控相互独立、传输距离与传输速度相互限制的问题,通过增加总线并行中继器、破解通讯协议、改变网络结构等方案,实现了触探数据采集与设备测控集成一体和延长通讯距离的目标,并在此基础上开发了数据采集与测控系统软件,最终保证了2008年9月在南海万山群岛海域开展海底CPT数据采集的顺利有效进行。The data acquisition and communication system is an important component of the technology R D in downhole offshore CPT equipment,for the problems of CPT data acquisition and equipment monitoring are independent of each other,and the transmission distance and speed limits on each other,some solutions were brought forward by adding the parallel bus repeater,breaking the communication protocol and changing the network structure,etc.and also realized incorporating the data acquisition and equipment monitoring and extending the transmission distance,based on the solutions,the software of data acquisition and equipment monitoring was developed,and so guaranteed the data acquisition is smooth and effective in Wanshan waters,South China Sea in September,2008.
