FIG. 1 is a diagram showing an entire configuration of a management system to which a method for managing manhole information according to the present invention is applied. The manhole 1 is for laying, maintaining and inspecting a communication cable as a communication means. The manhole 1 may be a manhole in which a communication cable, a repeater, and the like are laid in a sewer or the like. The manhole 1 is usually buried in a road 2 and provided with an entrance 3 through which people can enter and exit from above, and a lid 4 thereof is exposed on the road surface.

When the communication cable 5 or the manhole 1 itself is inspected, the vehicle is stopped to ensure safety, and then a person enters and exits the manhole 1. When the inspection is not performed, cover 4 is placed at the entrance. The lid 4 is made of cast iron or concrete, and has a sufficient strength so that it does not break even when a vehicle passes. Further, measures such as preventing rainwater or the like from entering the manhole 1 are also taken. The manhole 1 is installed on a road 2 at a predetermined interval, and a communication cable 5 is laid underground between the manholes. The communication cable 5 is formed by bundling thin wires such as a copper wire and an optical fiber cable into a thick wire.

Connected. The communication cable 5 is passed through the duct 6. In the present embodiment, three communication cables 5, 4, 6, and 7 are laid. The three communication cables 5 are connected to the relay section (duct opening) of B in the manhole 1 to transmit a signal to the next manhole.

When the transmission destination is determined in advance, the communication cable 5 is a continuous communication cable 5 that is not branched.
Through the duct 6 of the manhole 1. The relay unit A or the relay unit B is connected to the handhole 7 and takes out a part of the communication cable 5 from the manhole 1. The communication cable 5a from the handhole 7 is drawn into the general house 2b, the building 2c, or the like via the utility pole 2a or a laying pipe buried underground to a cable connection destination around the manhole 1.

The handhole 7 is usually installed at a position such as a sidewalk away from the manhole 1, and is branched from the manhole 1 and connected to a communication cable 5b.
No one can enter or leave the handhole 7, but can work by putting his hand in the work. Therefore, when a new communication cable 5 is added and a new connection is made to a building or the like, the processing is usually performed in the handhole 7. The road surface side of the manhole 1 is the entrance 3 as described above, so that people can enter and exit during inspection work.

Normally, when there is no inspection work, the lid 4 is closed. In the present embodiment, the storage means 8 is arranged and fixed at or near the lid 4 and manages the manhole 1.

Although the method of the present invention has been described with reference to the embodiments based on the drawings, the specific method of the present invention is not limited to the embodiments.

[Other Embodiments] In the above-described embodiment, the position of the manhole 1 and the management number are specified from the digital information written in the storage means 8.
However, when the information of the storage means 8 cannot be read by the reading / writing means 10 and the management number and the position of the manhole cannot be specified for some reason or cannot be distinguished from other manholes such as sewers and waterworks, the following is performed. In a specific way.

First, the position of the manhole 1 is specified by a GPS card (or a chip) which has a GPS (global positioning system) function incorporated in the mobile computer 9. The information of the manhole 1 closest to the specified position information is taken out from the database server 12 and called out by the mobile computer 9, and if it matches with the shape, size and the like of the manhole 1 and matches, the management for identifying the manhole 1 is performed. Identify the number. Thus, information on the manhole 1 can be obtained.

This GPS is a global positioning system,
It is possible to measure an accurate position on the ground with a satellite system for position measurement. According to this GPS, the position of the relevant manhole 1 can be caught even if the distance from the relevant manhole 1 is some distance. Further, a GPS card may be incorporated in the manhole 1. In this case, there is a function that can specify the position of the manhole 1 even if the mobile computer 9 does not have a GPS function.

Although the storage means 8 has been described as an IC chip or an IC card, a method using a bar code is also possible. In this case, since confirmation by barcode shape identification is necessary, the administrator must go directly to the corresponding manhole 1 and directly read the barcode attached to the manhole 1 with a code reader (reading means).

Although there are drawbacks such as the inability to write updated data and the need to read directly from a barcode with a barcode reader, the place where the barcode is arranged is limited. It is also possible. The barcode is preferably composed of at least an Internet address and a management number for identifying a manhole. A barcode reader connected to the mobile computer 9 may read the barcode and connect to the database server 12 via a provider to obtain manhole information.

[0045]

As described above, according to the present invention,
Rather than recording in a paper document or CPU ROM format as in the past, management was performed by a mobile computer by providing information as data in manholes, so records could be lost. No, it can accurately and reliably identify and manage manholes.

Further, since the recording and analysis work can be performed on site, quick processing can be performed, and efficient manhole management can be performed. Furthermore, by making the manhole information on site into a database, the registration data is diversified, and analysis with other manhole information becomes possible, and detailed management information on manholes can be obtained.
