FIG. 1 is a schematic diagram showing a schematic configuration of a self-positioning system 1a used in the inspection information creation support system 1 according to the embodiment of the present invention. As shown in FIG. 1, the self-positioning system 1a requires five GNSS (Global Navigation Satellite System) satellites S in order to adopt the RTK positioning method (Real Time Kinematic GPS) which is an interference positioning method. With such a positioning method, it is possible to specify a position with high accuracy of about 1 to 10 cm.

As shown in FIG. 1, the reference station 10, the mobile station 20, and the positioning server 30 are each connected to a network N such as the Internet. The reference station 10 uses the GNSS observation information of the receiver R1 that receives the signal transmitted from each GNSS satellite S via the GNSS antenna A1 and the reference station 10 received by the receiver R1 as the GNSS correction observation information, and the network N. It has a server 11 that performs a process of transmitting to the positioning server 30 side via the above.

The mobile station 20 receives the signal transmitted from each GNSS satellite S via the GNSS antenna A2, and the GNSS observation information of the mobile station 20 received by the receiver R2 via the network N. It has a tablet terminal 2 for transmitting to the positioning server 30 side.

The positioning calculation unit 31 of the positioning server 30 calculates the self-position of the mobile station 20 based on the GNSS correction observation information transmitted from the reference station 10 and the GNSS observation information transmitted from the mobile station 20, and the mobile station 20. Send to. Specifically, in the RTK positioning method, the positioning calculation unit 31 calculates the position of the mobile station 20 based on the carrier wave phase between the receivers R1 and R2. However, since it is not known how many carrier wave waves exist between the receivers R1 and R2, it is necessary to determine the wave number of the existing carrier wave (integer value bias). This integer bias is determined by making a guess based on the GNSS corrected observation information and then obtaining a convergent solution. This convergent solution has a high accuracy with an error of about several centimeters.

FIG. 2 is a flowchart showing a self-positioning process procedure by the self-positioning system 1a. As shown in FIG. 2, in the self-position identification process by the self-position identification system 1a, first, the positioning calculation unit 31 of the positioning server 30 transmits the GNSS correction observation information and the mobile station from the reference station 10 via the network N. The GNSS observation information transmitted from 20 is acquired (step S101). After that, the positioning calculation unit 31 calculates the self-position of the mobile station 20 based on the GNSS observation information of the mobile station 20 and the GNSS correction observation information of the reference station 10, and outputs the self-position to the tablet terminal 2 via the network N. (Step S102). After that, the above-mentioned process is repeated.

As an example, the inspection information creation support system 1 provides inspection information creation support after the completion of the construction of the impermeable sheet at the waste disposal site. This inspection covers all the fusion points between the impermeable sheets, and includes a pressure inspection, a negative pressure inspection, and a spark inspection. The pressure inspection is applied to the inspection of the joining ship using self-propelled fusion, and air is sent by a pump or the like to increase the air pressure in the air channel and confirm that the pressure drop is 20% or less. Since a creep phenomenon occurs when a stress is applied to the impermeable sheet, the optimum pressure is set for each type of the impermeable sheet. Negative pressure inspection, also called vacuum box inspection, inspects for air leaks by depressurizing while pressing a vacuum box against a water-impervious sheet coated with soapy water. In the spark inspection, a conductive sheet is installed on the back side of the impermeable sheet, or a copper wire or the like is inserted in the joint to join, and a high voltage is applied between the brush and the ground to check for joining defects from the presence or absence of sparks. figure out.
