By reducing the weight of the cable, the tension of the cable is reduced, so that the disconnection that occupies most of the apparatus failure is eliminated, and the reliability of the apparatus is improved.
Further, the portable memory is made of any one of a USB memory, a floppy disk, and an SD card, so that the probe data can be easily transferred to the personal computer.
Further, when merging the cable speed data and the probe data when the cable is moved, the time of the probe data and the speed data is reduced by performing an operation by matching the probe data and the clock data of the speed data. It can be made to correspond exactly and a highly accurate measurement is attained.

DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a hole bending measuring device according to the present invention will be described with reference to the drawings.

In the hole 3 such as excavation or iron pipe, the shape of the hole 3 is measured using the length measuring device 5, the cable winder 6, and the calculation unit 7 including a personal computer by winding the probe 1 with the cable 11. Is configured to do.

The probe 1 is configured as shown in FIG. 2, and detection signals 2A and 2B as probe data from the gyro 2a and the accelerometer 2b of the hole measuring sensor 2 are supplied to the A / D converter 11A and the control circuit 21. Then, the detection signals 2A and 2B digitized are stored in the nonvolatile memory 20.
In the above case, a probe clock 22 is built in the probe 1, and the probe clock data 22a of the probe clock 22 is detected by the control circuit 21 and the probe clock data 22a is detected by the detection signals 2A and 2B. Is stored in the memory 20 in a state of being added.

  The personal computer receives the calculation / display / recording unit 14, the calculation unit clock 23, and speed data 5 a connected to the calculation / display / recording unit 14 and detecting the speed of the cable 11 from the length measuring device 5. The arithmetic unit clock data 23 a from the arithmetic unit clock 23 is input to the arithmetic / display / recording unit 14.

  Next, the operation will be described. First, in the above-described configuration, the detection signals 2A and 2B which are probe data from the gyro 2a and the accelerometer 2b forming the hole measuring sensor 2 are stored as detection signals 2A and 2B digitized by the A / D converter 11A. When stored in 20, the probe clock data 22a is simultaneously added to the detection signals 2A and 2B and stored.

  The detection signals 2A and 2B in the memory 20 stored in the memory 20 are any one of a USB memory, a floppy disk, an SD card, and the like by an operation of a memory device (not shown) having the memory 20. The speed data 5a of the cable 11 from the length measuring device 5 and the detection signals 2A and 2B, which are probe data, can be stored in the portable memory 30 and input to the calculation / display / recording unit 14. The calculation unit 7 merges, and at the time of the merge, the analysis is performed by matching the times of both recording data, thereby enabling high-precision measurement.

  For example, when the radio clocks are used, the clocks 22 and 23 are not problematic because the times of the clocks 22 and 23 are matched with high precision. However, in the case of a normal quartz clock or the like, 22 and 23 cause a slight time error, so that the time of each clock 22 and 23 can be automatically corrected every predetermined time by a time correction function using a well-known wireless type, GPS, or the like (not shown). It is configured.
