In the present embodiment, described CPU board preferably adopts the PC104 structure, connect the described degree of depth/drag board by the PC104 bus, with to the degree of depth/drag board sending controling instruction, coordinate the operation between each feature board, and can read the degree of depth/drag board at any time and calculate the depth-logger value that generates, after request that the main frame that receives logging system sends or reading signal command, the depth-logger value is transferred to main frame.
Concrete establishment structure to each feature board is described in detail respectively below.
The MMD/CCL disposable plates is mainly finished the level conversion to magnetic mark MMD and casing coupling detection signal CCL, and under the effect of the logic control signal that the degree of depth/drag board produces, amplification, filtering, the level finished primary signal keep and gain control.
Fig. 2 is the circuit structure block diagram of the MMD processing module on the MMD/CCL disposable plates.The magnetic mark probe is made up of Hall effect device usually, the magnetic mark MMD that produces is the difference small-signal of millivolt level, this signal can be via following several section processes: at first, after original magnetic mark MMD carries out computing amplification processing via the low pass discharge circuit, filter out the high-frequency crosstalk signal, and the base voltage of this signal is drop-down.The degree of depth/drag board utilizes the variable gain regulating circuit dynamically to regulate the gain of this signal according to the cable movement speed in when well logging, with the influence of elimination speed for signal amplitude, makes this signal have the comparativity on the sequential.Secondly, by the signal of variable gain regulating circuit adjustment output, after the logical operational amplification circuit processing of band, realize that the logical gain of band between 0.16Hz～160Hz is amplified.Afterwards, signal carries out exporting after 13 times the amplification through amplifying circuit, sends into the degree of depth/drag board by sampling channel 1 and does further processing.Meanwhile, the MMD signal of exporting by described amplifying circuit produces a magnetic mark detection judgment signal through a fixed value voltage comparator circuit on the one hand, exports the degree of depth/drag board to be used to annotate magnetic; Detect the peak level of magnetic mark MMD on the other hand through a peak detection circuit, export the degree of depth/drag board to, for sampling and comparing by sampling channel 0.
The CCL Signal Processing is the same with the handling principle of magnetic mark MMD, also is after the primary signal of casing coupling probe sampling feedback is handled via the low pass discharge circuit, to filter the high-frequency crosstalk signal, and the base voltage of signal is drop-down; Then, export the variable gain regulating circuit to, the amplitude of signal is controlled in the stable scope, so that the amplitude of carrying out relatively; After adjusted signal was handled through the logical operational amplification circuit of band, 5 times gain was amplified between realization 0.16Hz～16Hz; Afterwards, after the process amplifying circuit carries out one-level amplification processing again with this signal, export the degree of depth/drag board to by sampling channel 2.Its circuit theory diagrams can adopt structure shown in Figure 2 to set up and realize.
The degree of depth/drag board is mainly finished collection, processing, the counting to the depth signal of the wheel of the depth coding on logging truck cable wheel disc output, can calculate the girth that the cable wheel disc rotates by these count values, be the length of logging cable motion, thereby learn the position of logger in the down-hole.
The degree of depth/drag board is provided with MCU, CPLD large-scale digital ic, tension force processing module and A/D converter, as shown in Figure 1.Wherein, the tension force processing module receives the cable stretch signal TEN of tensiometer sampling feedback, exports A/D converter to after level conversion is handled.Its concrete structure of setting up can comprise differential amplifier circuit and operational amplifier referring to shown in Figure 3.After wherein differential amplifier circuit carries out one times of difference amplification processing with the cable stretch signal TEN that receives, be converted to single-ended signal, and after utilizing connected external reference voltage to change the reference voltage of described single-ended signal, export operational amplification circuit to and amplify processing, to satisfy A/D conversion range, do not reduce conversion accuracy simultaneously again.Described A/D converter is mainly finished the analog-to-digital conversion to each road analog sampling passage under the control of CPLD.As shown in Figure 1, the input end of analog signal of A/D converter is connected with the MMD/CCL disposable plates is corresponding with the tension force processing module respectively, receive cable stretch signal TEN, magnetic mark MMD and box cupling detection signal CCL, and under the control of CPLD, be data signal with analog signal conversion, transfer to CPLD by its digital signal output end.Described CPLD receives the depth signal of depth coding wheel feedback simultaneously, and is connected communication with MCU, exports each the road signal that receives to correction calculation that MCU carries out the depth-logger value.
