Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention stores and retains various kinds of information on road occupation properties, such as road information and underground buried objects, which can be read out and rewritten on site without contact. The present invention relates to a curb which can be used as a line marker of a traffic system (ITS) or an information medium of VICS.

[0002]

2. Description of the Related Art There are various road occupied properties such as water and sewage, gas, and various telecommunication cables on roads, and information on these occupied road properties is generally referred to as locally installed information. There is an example in which the nameplate on the back of the lid describes the depth of the inside of the manhole, the burial information such as the position of the buried pipeline, the road map, the previous construction status, and precautions when workers enter.

However, people and vehicles come and go on the manhole, and it is necessary to open the lid to obtain information. For this reason, traffic is restricted and safety confirmation personnel are also required. Furthermore, since the manhole cover is heavy, it requires special tools for opening and closing, and there is a difficulty in workability. It is rare that the nameplate is updated, and it has been difficult to easily find useful road private property information in advance.

[0004] If information is written on the back of the manhole cover, it may be difficult to confirm the location of the manhole in some areas because the information is covered with snow or fallen leaves.

On the other hand, in recent years, with the diversification, sophistication, and complexity of road-exclusive properties, it has been desired to consolidate road-exclusive property information and road management information. The intervals were uneven and the manhole density was low in some places, making it unsatisfactory as a location for installing aggregate information.

[0006] Intelligent transportation systems (ITS) and V
Like ICS, a system for guiding vehicles and transmitting road information to vehicles has been developed, and practical use is approaching.
It is desired to provide comprehensive information provision means on roads. In the case of a system that transmits information to a moving object such as a vehicle and also updates the information, it is necessary to have multiple information transmission directions and to minimize interruption of traffic during data input / output work. .

[0007] Further, the information medium can be easily attached to an existing installation and exchanged. In addition, in the case of reading and writing data, in the case of reading by the electromagnetic induction method, signal transmission is insufficient if there is a metal nearby. Therefore, it is desired that such information does not occur because the information cannot be read.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and enables various road private property information and road information to be retrieved in a non-contact manner. It can be easily performed, and can collectively manage and use road private property information and road information collectively.
Furthermore, as in the case of the Intelligent Transport System (ITS) and VICS, it is possible to guide vehicles and to easily transmit road information to general vehicles, and to perform data reading and rewriting without interrupting traffic. It is an object of the present invention to provide a road installation that stores private property information.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a read-only type in which road occupation property information, road information, and the like are written on a curb that is continuously installed along a road. A rewritable storage medium is buried, and depending on the storage medium, it can be used as a line marker of the Intelligent Transport System (ITS) or a VICS if it can communicate with satellites. is there.

According to the present invention, the curb of the present invention can be easily obtained by inserting a box containing a storage medium after forming a small hole in an existing or new curb, and Can be easily replaced.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example in which an IC chip 2 as a storage medium is embedded in the curb 1 in the vertical direction and on the side surface on the road side. IC
In chip 2, information on the exclusive use of the road, such as the location information of the manhole, the date of installation, the department in charge, and, if necessary, the type of underground cable line and maintenance information, are written.
A read-only read-only type, a rewritable read / write type, or a type capable of communicating with a satellite can be considered. The IC chip 2 may be of a type that requires a power supply, but may be of a type that operates by radio waves transmitted from the reading side and does not require a power supply on the element side.

The IC chip 2 buried in the vertical direction performs reading and writing from the upper side of the curb. For example, information on road occupation property such as a buried pipe position and a map, information on the structure of the road, and information in the horizontal direction are provided. The embedded IC chip 2 is suitable for use in transmitting a line marker or road traffic information to a running vehicle. In the figure, both the vertical and horizontal sides are buried in the curb, but it can be selected as appropriate depending on the road condition and information content, such as vertical only or horizontal only.

In order to embed the IC chip 2, a small-diameter hole for embedding the IC chip is previously provided in the curb, and the IC chip 2 is
The chip 2 is inserted and covered with the resin 4. The curb of the present invention can be easily obtained on a curb before installation on a road and also on a curb after installation.

FIG. 2 shows an example of a curb in which the IC chip 2 is detachably stored. A storage body 5 is embedded and fixed in the hole 3 on the curb top surface or side surface. An IC chip 2 covered with a resin 4 is detachably housed in the hole 3. The housing 5 is provided with a lid 6, which has a lock function, and unlocks the lid with a key 7. The secret is stored in the IC chip 2,
By linking with the lock function, it is also possible to restrict access only to authorized persons.

The information stored in the IC chip 2 is read using electromagnetic induction, and the information is displayed on a display. Further, new information can be rewritten in the IC chip 2 in a non-contact manner. Reading is performed by electromagnetic induction.If the IC chip is embedded in the iron casting of the manhole cover, the signal may not be transmitted sufficiently due to the presence of metal. There is no.

Further, since the curb is continuously installed on the road side, it is possible to connect individual IC chips and collectively manage such information in one place. It can also be used to transmit road traffic information. Collect the detachable IC chip 2 and intensively and regularly rewrite the road information and road private property information.
Make rewriting work routine, and make updating work more efficient.
