Description

Excavation goggles with RDF antennas for the prevention of excavation accidents and excavators including them {EXCAVATOR WITH A BUILT-IN RFID READER TO PREVENT THE DIGGING ACCIDENTS}

The present invention relates to an excavation gourd for preventing excavation accidents, and relates to an excavation gourd equipped with an RFID antenna capable of recognizing underground works equipped with an RFID tag.

RFID (Radio Frequency Identification) is a next-generation recognition technology that can manage the information of various objects such as food, animals, and objects through IC chip and wireless.It has excellent storage capacity and real-time information as compared to the existing barcode. The advantage is that it can be recognized even at high distances. Such RFID technology includes an RFID tag that provides information, an RFID antenna that radiates RF (Radio Requency) to receive the information, and an RFID reader that reads and decodes the information obtained by the RFID antenna. It is composed.

Underground works such as water pipes, sewer pipes, gas pipes, and telecommunication cables are generally buried along roads, and roads are always excavated due to various constructions. In particular, LNG buried pipes are particularly dangerous in that there is a risk of a large fire in an excavation accident.

Currently, the underground buried indicator with RFID tag is disclosed in Korean Laid-Open Patent Publication No. 10-2007-0078826, but even if the location or structure of the underground buried is not informed of such a change, a drilling accident may still occur. There is a problem that the risk is high.

In addition, Korean Laid-Open Patent Publication No. 10-2005-0050454 discloses an underground buried detection system having an underground buried with an RFID tag and a terminal equipped with an RFID reader. In the basement, the maximum RFID recognition distance is not as large as 50 cm. There is a problem that it is difficult for an excavator operator who directly performs excavation work to recognize the existence of underground burial.

The technical problem to be achieved by the present invention is to provide an excavation gourd equipped with an RFID antenna to immediately grasp the location of the buried underground and various information of the buried during the excavation construction.

The present invention is characterized in that the excavation gourd is equipped with an RFID antenna that can recognize the underground buried with the RFID tag. The frequency used by the RFID antenna is preferably characterized in that 915 to 923.5MHz. The present invention provides an excavator including the excavator gourd. In addition, the present invention is characterized in that it further comprises a display unit for displaying the information received from the RFID antenna on the excavator including the excavation goggles equipped with the RFID antenna.

Excavation work using the excavation gourd according to the present invention can immediately recognize the presence of underground buried in the field to prevent accidents that damage the underground buried in advance, and furthermore, leak, explosion accident Etc. can be prevented.

FIG. 1 is a diagram showing the underground works 100 equipped with the RFID tag 111.
2 is a view showing an excavation gourd 200 equipped with an RFID antenna 211.

Hereinafter, the present invention will be described in more detail.

The present invention relates to an excavation bag 200 equipped with an RFID antenna 211 capable of recognizing the underground buried material 100 on which the RFID tag 111 is mounted.

The RFID tag 111 may be manufactured by being attached to the underground works 100 itself during the manufacturing process of the underground works 100, or may be attached to the surface of the buried goods in the process of embedding the underground works 100.

The RFID tag 111 has a built-in RFID chip, the embedding date of the underground buried 100, the buried engine, the type of buried, the size of buried, the category of buried, the depth of the buried, buried Data, such as the shape, the direction of the buried material may be included.

The RFID chip is divided into an active type with its own power source and a passive type without its own power source. The RFID tag 111 is attached to the underground buried material 100 to continuously supply power from the outside. It is preferable to use the passive type because it is not easy to supply and only the information of the buried material is provided through the RFID reader when necessary.

The RFID antenna 211 wirelessly transmits and receives data to and from the RFID tag 111 using RF (Radio Frequency), and may also use an ultra high frequency (UHF) band of 900 MHz, and a low frequency (LF) band of about 125 KHz. Can also be used.

The maximum recognition distance of the RFID antenna 211 is reduced to about 50 cm in the basement when using the 900 MHz UHF (Ultra High Frequency) band, which has a relatively long recognition distance, so that the RFID tag 111 is underground. It is reasonable to attach to 100 at intervals of about 50 cm.

The RFID antenna 211 is a portion that radiates radio waves to the RFID tag 111, and since the radio waves have directivity, the RFID antenna 211 is located on the inner side of the excavation bag 200, that is, the side containing the excavation object. Valid

In order to protect the RFID antenna 211 installed in the excavation gourd 200 it is reasonable to install a protective film such as acrylic, glass material. The protective film may be formed of any one or more of acrylic, glass, tempered glass, plastic or carbon reinforced fiber.

According to one embodiment of the present invention in the cockpit of the excavator equipped with the excavation gourd 200, the excavator driver can immediately obtain the relevant information on the display unit so that the various information of the underground buried 100 received by the RFID antenna 211 It is reasonable to have an RFID reader (display) for displaying, and the RFID reader is connected to the RFID antenna via a wire. The RFID reader may be a removable reader.

The RFID antenna 211 is not necessarily limited to attaching to the excavation gourd 200 of the excavator, and may be used by attaching to any mechanism used for excavation. For example, it can be used by attaching to the loader's gourd, bulldozer's gourd, etc.

≪ Test Example 1 >

In order to find out the underground recognition distance of the RFID antenna 211, the frequency of 900MHz band is used, the underground tag 100 is equipped with a metal RFID tag 111, and the excavator gourd 200 of the excavator The antenna 211 was mounted. The results are shown in Table 1.

Underground depth Reader distance from ground Effectiveness Maximum 5cm 49 cm 55cm 10 cm 46 cm 52 cm 15cm 39 cm 47 cm 20cm 32 cm 40cm 25cm 26 cm 33 cm 30cm 17 cm 26 cm 35cm 15cm 22 cm 40cm 13 cm 19 cm 45cm 10 cm 15cm 50cm 7 cm 11 cm 55cm Unstable 3 cm

≪ Test Example 2 &

When 5cm thick concrete is covered on the soil, the frequency of 900MHz band is used to determine the recognition distance of the RFID antenna 211, and the RFID tag 111 made of metal is mounted on the underground works 100, and an excavator The RFID antenna 211 was mounted on the excavation gourd 200. The recognition distance was reduced slightly compared with the experiments in general soil, and the results are shown in Table 2.

Underground depth Reader distance from ground Effectiveness Maximum 5cm 46 cm 50cm 10 cm 40cm 46 cm 15cm 35cm 39 cm 20cm 29 cm 33 cm 25cm 22 cm 29 cm 30cm 16 cm 23cm 35cm 11 cm 18 cm 40cm 9 cm 13 cm 45cm 5cm 9 cm 50cm Unstable 2 cm
