The present invention relates to a surveying system of underground facilities using a laser range finder that can output and analyze various types of information of underground facilities in the required form.

In modern times, due to the improvement of social, cultural and industrial standards, underground areas near residential areas have numerous underground areas such as water and sewage pipes including gas pipes, oil pipelines, communication and power cables, various ducts and storage tanks. Facilities are present.

In Korea, the high-pressure pipe network of 10 ~ 70㎏ / ㎠ operates over 1,300km as of the end of 1997, and it is expected to reach 2,000km within a few years. Therefore, the location information must be accurately identified for the repair and management of underground facilities. Of course, it is necessary to manage effectively according to the records, but the degree of damage caused by various accidents occurring during various constructions due to lack of accuracy is increasing continuously.

Conventionally, when underground facilities are buried, before filling up the soil, one of the measuring workers supports the target while another worker checks the position of the target using public survey equipment such as a total station on the ground. Although it uses a method or a surface, it has a problem that it is difficult to expect accuracy.

In addition, the method of using a pipe locator is the most commonly used method, which has the advantage of being relatively accurate and simple, but has a disadvantage in that the accuracy is greatly reduced due to interference in places where facilities are complicatedly buried, such as downtown. Has advanced to the point of using GPR exploration equipment.

This method uses high frequency electromagnetic wave and received signal processing method to detect the position of the object, but it is a device that detects various structures and stratum structures existing in the basement, but the overall configuration of the equipment is complicated and considerable experience to accurately analyze the detection result. There is considerable difficulty in commercialization because the detection results are very sensitive depending on the soil properties.

These underground facilities can be managed by geographic information system (GIS).

The tablet 3000 may output the multimedia information if the facility is made of multimedia, and wirelessly connected to the underground detection equipment 2000 by the Wi-Fi method, and the underground detection equipment read from the tag unit 1000 operated by the RFID method. Check (read) underground installation information and save it in the assigned area.

The tablet 3000 inputs the measured environmental information related to the underground facilities in the field and stores it in the allocated area, and the environmental information includes surrounding environment information, state information, standard information, and the like.

The tablet 3000 analyzes the set state and determines whether the tablet 3000 is set to update and input the environmental information measured in the field into the management computer in real time.

If it is determined that the tablet 3000 is set to update the environment information into the management computer in real time, the tablet 3000 accesses the management computer 5000 in real time via the mobile communication network 4000.

On the other hand, if it is determined that the tablet 3000 is set to input the environment information directly into the management computer online, the controller 3000 accesses the management computer online.

The tablet 3000 outputs the environmental information measured in the field and transmits it to a management computer connected in real time or online.

The present invention of the configuration as described above is to download the GIS information of the underground facilities being managed using a tablet and directly input to the tablet by measuring the coordinate information, standard information, etc. in the field to reduce the input error of information and update management in real time quickly and accurately At the same time, it is possible to generate various statistical data by analyzing existing management information of the underground facilities and measured update management information.

While the present invention has been described in detail with respect to the embodiments described, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical spirit of the present invention, and such modifications and modifications belong to the appended claims.
