DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a device configuration for explaining the buried object search device of the present invention.
In FIG. 1, the same reference numerals as those in FIG. 3 denote the same or corresponding parts. Reference numeral 10 denotes a main body circuit unit. The main body circuit unit 10 includes a display circuit 11, an arithmetic circuit 12, an electromagnetic wave transmission / reception circuit 13, and the like.
Reference numeral 20 denotes an antenna unit that transmits and receives electromagnetic waves.
[0010]
When the power switch is turned on, the electromagnetic wave is transmitted downward from the antenna unit 20, the reflected wave reflected by the buried pipe is received, and the search image 103 is displayed on the display unit 2 by the display circuit 11.
The movement distance of the apparatus main body 1 during measurement is measured by the arithmetic circuit 12 from the number of rotations of the wheel 5, and the depth to the buried pipe 102 is measured by the arithmetic circuit 12 from the electromagnetic wave transmission / reception time in the electromagnetic wave transmission / reception circuit 13. For example, the display unit 2 is provided with a distance memory (unit: m) on the vertical axis and a depth memory (unit: cm) on the horizontal axis with reference to the traveling direction of the apparatus, and the search image 103 is displayed on the display unit 2 by the display circuit 11. However, the distance and depth to the buried pipe 102 can be determined depending on where the information is displayed.
The configuration so far is the same as that of the conventional buried object exploration device.

Reference numeral 30 denotes a main body direction detecting device (also referred to as a main body direction detecting means in the present specification) for detecting the orientation of the apparatus main body 1. When the orientation of the apparatus main body being measured is detected and the vertical relationship is reversed, (For example, in FIG. 4, the posture in which the exploration in the direction of arrow (A) is performed is the forward direction, and the posture in which the exploration in the direction of arrow (B) is performed is the opposite direction). Perform the output operation.
The main body direction detection device 30 can use an existing detector that detects the forward / reverse direction of the top and bottom direction, and is forward / reverse only when the main body 1 of the wall surface 101 is searched in a horizontal direction as in the search of the wall surface 101. It can be set as the structure which performs a detection.
[0012]
Reference numeral 40 denotes a display inversion unit, which sends a command to the display circuit 11 when a signal from the main body direction detection device 30 or the manual inversion switch 50 is input, and inverts the display direction of the measurement data on the display unit 2 up and down. I do.
Reference numeral 50 denotes a manual reversing switch operated when it is desired to manually reverse the display direction of the measurement data.

FIG. 2 is a diagram showing a display operation of the display unit 2 in the buried object search device of the present invention, and corresponds to FIG. 5 of the conventional device.
When the power source is turned on and the main body of the apparatus is in a horizontal posture for exploring the concrete wall 100 as shown in FIG. 4, the main body direction detecting apparatus 30 has a vertical direction that is a predetermined forward direction or a reverse direction. If it is in the opposite direction, a signal is output to the display inversion unit 40, and the display inversion unit 40 operates the display circuit 11 to invert the display of the distance scale and the depth scale, and the distance after the inversion And the exploration image 103 is displayed according to the display scale.
[0014]
That is, as is clear from the comparison between FIG. 2 and FIG. 5, in the exploration in the positive direction (A direction), the distance scale is displayed at the top of the display unit 2, and the depth scale is displayed deeper as it goes downward. Even when the vertical relationship of the apparatus main body 1 is reversed in the search in the opposite direction (B), the distance scale is displayed on the upper part of the display unit 2, and the depth scale is inverted and displayed so as to become deeper downward. In accordance with this, the exploration video 103 is displayed.
Therefore, even when a search is performed with the vertical relationship of the apparatus main body 1 reversed, the display of the measurement data is automatically reversed and displayed without a sense of incongruity for the apparatus user, and the possibility of erroneous recognition can be prevented.
[0015]
The difference in the display direction of the display unit 2 is also a problem for the user of the apparatus. Therefore, the display is not automatically reversed as described above, but is manually reversed when the display reversal switch 50 is operated. It is good also as a structure.
