| 摘 要： | 利用脉码调制技术和时分复用技术对现有的多总线数据传播综合录井仪进行改进，通过在井台区设置一个接口箱，使录井仪的主机柜与接口箱之间只用一根总线连接，变多总线数据传输方式为单总线数据传输方式。改进后的仪器维修、保养、安装、拆卸方便，同时还降低了仪器的生产成本。

| Abstract: | The current integrated well log instrument with multiple bus data transfer is improved by using pulse-code modulation and time division multiplex. By designing an interface box on well platform, the main cabinet of the well log instrument is connected to the box with only one bus ,thus multiple bus transfer is changed into one bus transfer. Being improved, the instrument is easy to maintain ,install and dismantle and the cost of the instrument manufacturing is also reduced. |
