Embodiment 1

[0064] Such as Figure 1-5 Among them, a method for measuring the plane position information of underground corridors, relying on the infrared positioning device 1 to cooperate with mobile phone software and computer terminals, according to the shape and direction of the corridor, it is divided into straight corridors, curved corridors and inclined corridors for measurement , which is characterized by:

[0065] The device layout steps of the linear corridor measurement specifically include:

[0066] 1) Install a set of infrared positioning devices 1 on the two side walls of the corridor along the direction of the corridor;

[0067] 2) The maintenance personnel use the mobile phone to locate their own position information in the corridor in the coordinate system;

[0068] The device layout steps of the curved corridor measurement specifically include:

[0069] 1) Install an infrared positioning device 1 on the outer wall of the curved corridor with the smallest curvature rad...

Embodiment 2

[0091] Such as figure 2 , on the basis of embodiment 1, step 3) of described data processing step specifically comprises the following steps:

[0092] 1) The infrared positioning device 1 pre-measures the position data AB of the corresponding opposite corridor side wall within its measurement range and uploads it to the static database;

[0093] 2) The infrared positioning device 1 compares the location information of the maintenance personnel sent by the computer terminal with the uploaded data in the static database;

[0094] 3) If the location information of the maintenance personnel sent by the computer terminal overlaps and matches with the uploaded data in the static database data, the location information of the maintenance personnel will not be included in the database;

[0095] If the location information of the maintenance personnel sent by the computer terminal intersects but does not match the static database data, the location information of the maintenance pers...

Embodiment 3

[0102] Such as Figure 4 , on the basis of Embodiment 1, in the step 3), when the maintenance personnel are located in the intersection d of the measurement ranges of two adjacent infrared positioning devices 1, the adjacent two infrared positioning devices 1 can detect independent Data, through the independent data detected by the two infrared positioning devices 1, the coordinates of the maintenance personnel are calculated and uploaded to the computer terminal.

Abstract

The invention relates to a method and a device for measuring plane position information of an underground gallery. The method comprises the following steps of: performing measurement of a gallery which is divided into a linear gallery, a curved gallery and an inclined gallery according to the shapes and the trends of the galleries by adopting infrared positioning devices matched with mobile phone software and a computer terminal, wherein the infrared positioning devices comprise a stepping motor, infrared distance measuring devices, a signal relay station and a main control core processing area, the stepping motor is connected with the two infrared distance measuring devices, and the infrared distance measuring devices take the stepping motor as an axis and are symmetrically distributed. By adopting the method and the structure mentioned above, the problems in the background technology can be solved, the position of overhauling personnel in the gallery can be accurately positioned, an information interaction channel is provided for the overhauling personnel at the upper and lower positions of the gallery, and the overhauling operation can be smoothly performed.

Description

technical field [0001] The invention relates to the technical field of corridor construction, in particular to a method and device for measuring planar position information of an underground corridor. Background technique [0002] In recent years, with the improvement of hydraulic engineering construction, the underground maintenance of hydraulic structures has gradually attracted attention. As the distance from the ground increases, the connection between underground maintenance personnel and ground monitoring personnel and the search for maintenance points have become a difficult problem to solve. Due to the inconvenience of signal transmission in the underground corridor, the maintenance information in the underground corridor cannot be transmitted to the monitoring and control terminal in time, and the maintenance personnel in the underground corridor cannot determine their specific location, and cannot accurately and quickly find the next maintenance point. At the same...
