刘勇:DFS-V数宇地震仪M-n故障的检测与维修,《石油地球物理勘探》,22(3)1987:353～357,340美国德克萨斯仪器公司生产的DFS-V数字地震仪电路设计比较合理,性能比较可靠,有一套联锁系统和通过OVERRIDE的控制达到超控某些故障条件的目的。为了获得良好的野外采集资料,使仪器在正常状况下运转,在控制部件上设置了故障与状态显示窗。在仪器内显示逻辑板(DL)的控制下,把63种故障与状态的信息装入一个32位移位寄存器中,由磁带运动板(TM)、头段逻辑板(HL)和显示逻辑板(DL)上的四个八位移位寄存器组成状态与故障检测系统,通过三位字符显示器在显示窗上显示出故障与状态。这里仅分析63种故障与状态的M-n故障的检测电路和维修方法。
Liu Yong: Detection and Maintenance of Mn Fault in DFS-V Digital Seismograph, Petroleum Geophysical Prospecting, 22 (3) 1987: 353-357,340 DFS-V Digital Seismograph Circuit Design by Texas Instruments Incorporated More reasonable, more reliable performance, a set of interlocking systems and OVERRIDE control over some of the conditions to achieve the purpose of failure. In order to obtain good field data collection and to operate the instrument under normal conditions, fault and status displays are provided on the control unit. Under the control of the instrument display logic board (DL), 63 fault and status messages are loaded into a 32-bit shift register consisting of the tape sports board (TM), header logic board (HL), and display logic board (DL) on the four eight-bit shift register state and fault detection system, through the three-character display in the display window shows the fault and status. Here only the analysis of 63 kinds of fault and status of the M-n fault detection circuit and maintenance methods.
