当前,日本各煤矿对与安全相关联的情报、数据的集中控制,都给予了高度重视。然而,与日俱增的大量情报、数据、给传统的通讯线路的增设,带来了很大困难。 为解决这一难题,1985年 5月前记同煤矿采用了能输送大量数据的光导纤维通讯方式,进行了连续6个月的井下现场实验。这种方式是把传统的井下数据传输信号装置,变换为井
At present, Japan’s coal mines attach great importance to the centralized control of information and data related to safety. However, the ever-increasing large amount of intelligence and data have brought great difficulties to the establishment of traditional communication lines. To solve this problem, in May 1985, Qianji used the optical fiber communication method that can transmit large amounts of data with the coal mine, and conducted a continuous downhole field experiment for 6 months. This method transforms the traditional downhole data transmission signal device into a well
