Description

  The present invention provides an RFID tag that stores an IC chip in which management information of facility equipment is recorded, a portable terminal that reads and writes information of the RFID tag, and is connected to the portable terminal to access the RFID tag. The present invention relates to a record information reading / writing structure of an RFID tag including a pen-type antenna device.

  An RFID tag storing an IC chip in which management information of each equipment device constituting the plant is stored is attached to each equipment device, and in the case of inspection / maintenance of the equipment equipment, the RFID tag is used from a mobile terminal. Conventionally, there is a system that manages and operates each facility device by reading the management information of the facility device and writing information such as an inspection result in the RFID tag at the end of the work.

  An RFID tag can record more information than a bar code and can be easily rewritten.

Further, the RFID tag has an advantage that information can be read and written in a non-contact manner, and information of a plurality of RFID tags can be collectively read.
However, in the case where the same type of equipment is densely arranged, such as food plant equipment, even if it is a handheld portable terminal, it should be placed close to the RFID tag attached to each equipment. In addition, it is difficult to selectively collect one piece of information to be specified.

  In order to solve the above problem, as shown in FIG. 7, an antenna device 71 for accessing the RFID tag 70 is provided independently from the portable terminal 72, and the antenna device 71 is formed in a pen shape so that each facility is provided. An RFID tag of a facility device to be read or written is provided with a switch portion 75 that can be easily inserted into a narrow interval 74 between the devices 73 and that can turn on / off information reading and writing functions of the RFID tag 70. Conventionally, there is an RFID tag record information read / write structure that reads or writes information only when it is in contact with 70.

FIG. 6 is an overall side view of a conventional pen-type antenna device 71.
As shown in FIG. 6, a conventional pen-type antenna device 71 is disposed so as to protrude from an antenna device main body 76 having a predetermined length and a predetermined length, and one end 77 of the antenna device main body 76. The antenna coil portion 78 is formed from a tip member 79 that is fitted into one end portion 77 of the antenna device body portion 76 and that can cover the antenna coil portion 78 from the outside, and is formed in a hollow truncated cone shape. ing.
In addition, the reading and writing functions of the antenna device 71 are turned on at a substantially central portion in the length direction of the side surface of the antenna device body 76. A push button type switch portion 75 that can be turned off / off is disposed, and a connection cord 83 connected to a portable terminal 72 (not shown in FIG. 6) is provided on the other end portion side 82 of the antenna device main body portion 76. It is connected.

As shown in FIG. 7, when accessing the information of the RFID tag 70, the RFID unit 70 is pressed by pressing the switch unit 75 in a state where the leading edge 80 is in contact with the RFID tag 70 to be read. Read and write information.
By the above operation, information can be read or written only to the RFID tag 70 attached to a predetermined equipment.

However, as shown in FIG. 7, in the conventional pen-type antenna device 71, it is necessary to bring the leading end 80 of the tip member 79 into contact with the RFID tag 70 to be read and written. If the distance 74 between the adjacent equipment device 73a is smaller than the length of the antenna device main body 76, the cutting tip 80 is brought into contact with the RFID tag 70. Therefore, even if it is going to arrange | position the said antenna apparatus main-body part 76 between the said equipment equipment 73 and the equipment equipment 73a adjacent to the said equipment equipment 73a, the equipment equipment 73a adjacent to the said equipment equipment 73 becomes obstructive. 73a between the antenna device main body 76 and the equipment device 73 along the length direction of the antenna device main body 76, Serial read or write operations of the RFID tag 70 becomes difficult, as a result, had the disadvantage that constrain RFID tag 70 to the equipment that can be mounted is generated.
Also, as shown in FIG. 8, since the distance dimension Q between the side surface portion 81 of the tip member 79 and the antenna coil portion 78 is large, the side surface portion 81 of the tip member 79 is connected to the RFID as shown in FIG. Even if the RFID tag 70 is brought into contact with the tag 70, the radio wave emitted from the antenna coil section 78 cannot be received, so that information cannot be read and written.
