Description

Location information cover {POSITIONAL INFORMATION MARKER}

The present invention relates to a location information sign, which is installed on a road or a floor, and forms a storage compartment inside the location information sign and then installs an electronic tag (RFID tag) that is kept watertight. Information and intellectual information (or survey information, or a variety of location information, including 圖 根 點) is to be provided contactlessly.

In general, in order to obtain accurate survey results in surveying work such as cadastral surveying and civil surveying, a reference point is used as the basis of the work. In the past, the surface of stone was embedded in the ground, but recently, a cover material made of synthetic resin is used in the ground.

On the other hand, the survey control point markers mainly installed on roadsides and sidewalks have a "+" shaped intellectual approach point displayed on the survey control point markers or survey control point markers due to the installation or replacement of water pipes, city gas pipes, etc. There are many cases where this loss or damage can not be used.

In addition, during the surveying operation, the reference point coordinates are input to the surveying equipment. In the related art, it is inconvenient because the operator manually inputs the coordinate values recorded on the cover point management book made of paper. It is not only cumbersome but also has a disadvantage of low reliability. In addition, the processing and management of survey results are performed in non-real time, so the efficiency is low.

In addition, detailed information on various underground works such as gas pipes, communication cables, power transmission cables, oil pipelines, water / sewer pipes, manholes, and bomb shelter are provided in a non-electronic form. There is an inconvenience to refer to the management ledger with reference to, there was a problem that can not cope quickly in various construction or accidents because they can not be comprehensively managed.

An object of the present invention is to provide a variety of underground buried and intellectual location information marker that can provide a variety of information of the intellectual information and underground buried in a non-contact.

Another object of the present invention is to form a storage compartment in the inside of the cover, characterized in that to easily install or easily replace the electronic tag (RFID tag, etc.) that is kept watertight (水密).

Still another object of the present invention is to form a barcode containing the information of the electronic tag on the surface of the location information marker, so that it can be transmitted to the outside so that the location information marker can be easily recognized by a barcode reader. do.

Still another object of the present invention is to make it easy to configure an electronic tag antenna having excellent performance by using a conductive electronic ink.

The present invention forms a storage compartment inside the location information sign, which is installed on the road or the floor, and then install an electronic tag (RFID tag) so that it can be easily installed or replaced easily, and can sufficiently withstand driving vehicles or external shocks. It is composed.

In addition, the present invention is configured to maintain the watertight of the electronic tag by using a sealing means such as a synthetic resin or a coating means, even if moisture or rainwater penetrates into the storage chamber, the normal operation of the electronic tag is achieved.

In addition, the present invention relates to various types of underground information such as gas pipes, communication cables, power transmission cables, oil pipelines, water / sewer pipes, manholes, air defenses, etc. Direction and depth information, coordinate information, location information, quantity information such as quantity, pressure, capacity, voltage, cross-sectional size, installation time information, installer information, manager information, connection history information, etc. Information other than the various information listed in the above is included.

In addition, the present invention can be easily found by a non-contact method by the electronic tag even if the location information cover sphere is buried underground by construction such as fill cover, and also forms a barcode containing the information of the electronic tag on one end of the location information cover sphere It can be easily recognized not only by the electronic tag reader but also by the barcode reader by transmitting it to the outside, and it also forms the barcode by the electronic ink that emits the RF signal, and serves as the antenna of the electronic tag. Receive and recognize barcodes better.

The location information sign is made of a rigid metal or a high strength (reinforced) synthetic resin so as to be sufficiently protected from a driving vehicle or various impacts applied from the outside, and when the antenna is made of metal, the antenna is capable of transmitting and receiving RF signals. The buried or installed part is composed of high strength synthetic resin or reinforced synthetic resin so that it does not interfere with the propagation (transmission / reception) of the RF signal.

When a barcode containing the information of the electronic tag is formed (marked) on the surface of the electronic tag so that the electronic tag information can be transmitted instead, transmission or reception of the RF signal is impossible due to failure or other circumstances of the electronic tag. Multi recognition function is provided to recognize (identify) by barcode.

That is, when the electronic tag reader is not compatible according to the type of the electronic tag reader, when the reader function of the electronic tag reader is lost or lost, even when the electronic tag reader is not carried, it can be sufficiently coped with.

According to the present invention, an electronic tag (RFID tag, etc.) can be easily installed or easily replaced in a storage compartment of a location information cover, and the watertight of the electronic tag is maintained by a sealing means or a coating means such as a synthetic resin. Even if water or rainwater penetrates, there is an effect that the normal operation of the electronic tag is performed.

According to the present invention, the location information marker includes various location information (or network information) related to the measurement (intellect) by electronic tags (RFID tags, etc.), its data, gas pipes, communication cables, power transmission cables, oil pipes, water and sewage pipes, Types, directions, depth information, coordinate information, location information, scale information such as quantity, pressure, capacity, voltage, cross section size, installation timing information, installer information, manager information, connection history, etc. Information and the like are provided.

In addition, the present invention can be easily found by the non-contact method by the electronic tag even if the location information cover sphere is buried underground by construction such as fill cover, and also by forming a barcode at one end of the location information cover sphere to be transmitted to the outside barcode reader It can be easily recognized, and by forming a barcode with an electronic ink that emits an RF signal to serve as an antenna of the electronic tag, there is an effect of improving the transmission and reception of the RF signal and the recognition rate of the barcode.

In addition, the present invention can be recognized (identified) as a barcode when a bar code is formed on one end of the electronic tag to replace the information stored in the electronic tag, when transmission or reception of the RF signal is impossible due to a failure or other circumstances of the electronic tag. It is a very useful invention that has the effect of being given multiple recognition functions.
