RU188969U1 - Device for contactless identification and registration of objects - Google Patents

Abstract

The device for contactless identification and registration of objects is intended to control the movement of people, vehicles, and goods equipped with RFID tags across the border of the controlled area. The device consists of a cable bridge that forms the boundary of the controlled area, and RFID equipment mounted in it. In the cable bridge there is a cavity for accommodating an RFID antenna and an RFID reader interconnected with a cable with a connector. The RFID equipment is connected to a computer via a connecting cable. The device is fixedly mounted on the path of movement of the monitored objects so that the RFID antenna completely blocks the controlled passage with its electromagnetic field. Reading information from RFID tags occurs when an object is moved through a cable bridge. 3 il.

Description

The claimed utility model relates to devices for contactless identification and registration of objects, and is designed to control the movement of people, vehicles, and cargoes equipped with radio frequency identification tags (RFID tags), which are read when the object crosses the controlled zone (a checkpoint, checkpoint , store or warehouse doors, etc.).

An analogue of the claimed utility model is the MOD3® Portals RFID portal of the Jamison Door Company (http://jamisondoor.com/product-families/rfid-portals/products/mod-portals/index.html), containing RFID antennas, RFID- reader, power supply, connecting cables, placed inside the vertical racks, mounted on a prepared horizontal surface and mounted on the installation site using flat supporting platforms.

The main disadvantage of the analog is the placement of the RFID antennas, RFID reader and connecting cables in vertical racks, which are an obstacle to the movement of objects of identification and registration.

The closest in technical essence to the claimed utility model (prototype), is the “RFID Portal” for the patent for industrial design No. 102301, MKPO 10-05, publ. 03/02/2017 bulletin No. 3, containing RFID antennas, RFID reader, power supply, connecting cables, placed inside the U-shaped portal, installed on the prepared horizontal surface and fastened at the installation site using flat supporting platforms and cable extensions.

Common essential features with the claimed utility model are:

- the use of RFID antennas for reading identification information from RFID tags attached to monitored sites;

- the presence of an RFID reader, to which, using connectors with nuts, are connected RFID antennas, recording identification information obtained with the help of antennas.

The disadvantages of the prototype include:

- placement of RFID antennas, RFID reader and connecting cables in a large and heavy frame structure - a portal that requires, firstly, a large space for its placement, secondly, specially prepared places or foundations for its installation and, thirdly , the use of fastening elements (supports, anchor bolts, rope stretch), ensuring the stability of the portal during its operation;

- potential danger to objects of identification and registration in the event of a portal tipping due to loss of its stability due to collision with a transport portal, mechanical damage of fasteners, or wind exposure and, consequently, regular monitoring of the condition of portal fasteners.

The technical result of this utility model is to simplify the design of the device for contactless identification and registration of objects, increasing its reliability, ergonomics, safety, expanding the scope.

The technical result is achieved in that the device for contactless identification and registration of objects contains an RFID antenna and is connected to it with a cable with an RFID reader connector, jointly placed in the floor structure in the form of a cable bridge of the lowest possible height, allowing to place RFID equipment motionless

fixed on a horizontal platform with a hard surface inside or outside the premises on the path of movement of controlled objects.

The essence of the utility model is illustrated by drawings, in FIG. 1 shows a general view of a cable bridge with an installed RFID antenna and an RFID reader; FIG. 2 is a general view of a device for contactless identification and registration installed in a doorway; FIG. 3 - scheme of the device. The drawings show the following structural elements:

1 - the base of the cable bridge;

2 - channel cable bridge;

3 - fastening element;

4 - cavity;

5 - RFID antenna;

6 - cable bridge cover;

7 - cable;

8 - RFID reader;

9 - power supply cable;

10 - computer communication cable;

11 - doorway;

12 - floor;

13 - cable bridge;

14 - trolley;

15 - cargo;

16 - RFID tag;

17 - COMPUTER

The main structural elements of the proposed device are a cable bridge, RFID antenna, RFID reader. In the base 1 (Fig. 1) and the cover 6 of the cable bridge there is a cavity 4 in which

RFID antenna 5 and RFID reader 8 are located. Between themselves, RFID antenna 4 and RFID reader 8 are connected using cable 7 passing through channel 2 of the cable bridge. Channel 2 of the cable bridge to the RFID reader 8 also supplies the power supply cable 9 and the cable 10 of communication with the computer. For fixed mounting of the cable bridge in the place of its installation, fastening elements 3 are provided on it.

Device for contactless identification and registration of objects works as follows. The cable bridge with RFID reader 8 and RFID antenna 5 placed in it is placed and fixedly fixed with fastening elements 3 on the floor 12 of the doorway 11 (FIG. 2) on the path of movement of the objects being monitored. After turning on the device, the antenna completely blocks the controlled passage with its electromagnetic field. When crossing the border of the controlled area with cargo 15 (Fig. 4), for example, a vehicle or a person lying on a trolley 14 or carrying a RFID tag 16 with identification information on it (conventionally shown as "1111" in Fig. 4, "2222", "3333"), the electric current induced in the antenna of the RFID tag 16 by the electromagnetic field from the RFID antenna of the device 5, provides sufficient power to operate the integrated circuit of the RFID tag, and to transmit the response signal received by the RFID antenna 5 device being processed and registered emogo RFID-reader 8. RFID-reader 8 accumulates the received identification information and then transmits it to the computer 17. The information read from the RFID-label occurs during movement of carriers labels that greatly accelerates the process control.

Thus, this technical solution allows not only to improve the ergonomic characteristics of devices for contactless identification and registration of objects in terms of reliability, ease of installation and operational safety, but also to expand the scope of their application.

Claims (1)

Device for contactless identification and registration of objects, containing an RFID antenna and connected to it with a cable with RFID reader connectors, characterized in that the RFID antenna, RFID reader and connecting cable are placed in the floor construction in the form of a cable bridge as low as possible height, while the floor structure is made with the possibility of fixed fastening on a horizontal platform with a hard coating inside or outside the room on the path of movement of controlled objects.
