3 is a diagram illustrating an operation of a radio reader according to an embodiment of the present invention.

The present invention relates to a wireless reader for collecting information of a wireless tag, and more particularly, to a method for notifying a user whether a wireless reader performs an unusual operation.

First, a radio frequency identification (RFID) used in various devices or articles including a portable terminal device will be described. Wireless recognition technology is a system developed by changing production methods, changing consumer consciousness, advancing culture and technology, and eliminating disadvantages of barcodes and magnetic cards. Wireless recognition is a kind of contactless card, and when referred to as a contactless card, wireless recognition is most often referred to.

Unlike the contact card, the wireless recognition does not require the user to insert the card into the reader, and because there is no mechanical contact, there is no friction or damage, and there is little pollution or environmental influence. The antenna continuously radiates radio waves, and when the tag and the RFID are stored within the radio range, the antenna transmits its identifier and data to the antenna. At this time, the frequency of the radio wave used is 10 kHz to 300 kHz is used, mainly low frequency (134.2 kHz) is used. Hereinafter, the features of the radio recognition.

First, it can recognize several radio recognition tags at the same time and save time by enabling high speed recognition. Due to the above-described advantages, wireless identification tags are replacing barcodes or magnetic tags in the logistics field. Second, because of the long sensing distance, it is easy to apply according to system characteristics and environmental conditions, and the application area is wide. In the area of the contact smart card used in the existing parking control system, a wireless identification tag replaces the role. Third, it has long life due to its excellent environmental resistance. Since the user does not need to insert the RFID tag into the RFID reader and there is no mechanical contact, the error rate is extremely low even under frictional RFID tag damage or in adverse conditions such as dust, moisture, temperature, snow, and rain. Therefore, it is applied to many systems in open space. Fourth, it can pass through nonmetallic materials. Fifth, it is possible to recognize the moving object at high speed in recognition method. It takes only 0.01 ~ 0.1sec from antenna emission to ID recognition, so it can be installed and applied to automatic fare collection system of uninterrupted parking management, highway or tunnel.

FIG. 1 illustrates a conventional wireless recognition system including a wireless recognition reader 100 and a wireless recognition tag 102. As shown in FIG. 1, in order to read data stored in the RFID tag 102, the RFID reader 100 emits radio waves to the RFID tag 102. The radio recognition tag 102 converts the received magnetic energy into electrical energy and drives the converted magnetic energy. The radio tag 102 transmits the stored data to the radio reader 100 using the converted electrical energy. The radio reader 100 extracts necessary information from the data received from the radio tag 102.

In general, since the wireless recognition reader 100 does not notify the user of its operation state, the user cannot recognize the operation state of the wireless recognition reader 100. As described above, since the user cannot recognize the operation state of the wireless recognition reader 100, an unnecessary operation is performed to recognize the operation state. This unnecessary action results in a weakening of the user's concentration.

An object of the present invention for solving the above problems is to propose a method for notifying the user of the operating state of the radio reader.

Another object of the present invention is to propose a method of improving the concentration of the user by informing the user of the operation state of the wireless recognition reader.

Still another object of the present invention is to propose a method in which a user can recognize in real time whether a failure of a wireless recognition reader.

The present invention to achieve the above object is a singular motion detection unit for detecting an operating state of the radio reader; A control unit instructing the singular motion detection unit to detect an operation state of the wireless recognition reader, and instructing to notify the detected operation state; And a notification unit for notifying the operation state detected according to the instruction of the control unit.

Preferably, the unusual motion detection unit reads the data stored in the radio recognition tag, records the data stored in the received radio recognition tag, reads the data stored in the radio recognition tag, or If the failure, the success or failure of the recording of the data stored in the received RFID tag, and a collision with the RFID reader using the same radio resources around, the authentication information to read the data stored in the RFID tag Detects an operating state including when necessary.

In order to achieve the above object, the present invention comprises the steps of setting the operating state of the radio recognition reader to be detected; Detecting whether an operating state of the set wireless recognition reader is generated; And notifying the detected operating state. The present invention provides a method for detecting an operating state of a radio reader.

Preferably, the method of notifying the operation state displays the operation state on the display unit, notifies the operation state using voice, or notifies the operation state using vibration.

The present invention proposes a method of informing the user of the operation state of the radio recognition reader so that the user can recognize the operation state of the radio recognition reader. Hereinafter, the structure and operation of a radio recognition reader according to an embodiment of the present invention will be described with reference to the drawings.

2 illustrates a structure of a radio reader according to an embodiment of the present invention. The radio reader includes a receiver 202, a signal processor 204, a controller 200, an unusual motion detector 206, a display 208, and a voice generator 210. Of course, the wireless recognition reader may include other components in addition to the above-described configuration, Figure 2 shows only the configuration necessary for convenience of description.

The receiver 202 receives a signal transmitted from a radio recognition tag. Of course, the receiver 202 may receive data from at least two radio recognition tags using the same radio resource. That is, the RFID reader receives data from at least two RFID tags using the same frequency.

The signal processor 204 processes the signal received from the receiver 202. That is, the signal processor 204 processes the received signal to convert the signal received from the radio recognition tag into a signal that can be recognized by the radio recognition tag.

The singular motion detection unit 206 detects a singular motion of the radio reader. The time point at which the data of the radio recognition tag is read, the time point at which the data of the received radio recognition tag is recorded, the success or failure of reading the radio recognition tag data, the success or failure of recording the received radio recognition tag data, the same radio resources In the event of a collision with a radio recognition reader using a, authentication information is required to read data of the radio recognition tag, and the like. Of course, in addition to the above-described cases it is necessary to notify the user of the operation state of the wireless recognition lead is a special operation. In order to read data stored in the RFID tag, authentication information may be needed. That is, when the security of the data stored in the RFID tag is required or only to be transmitted to a specific RFID reader, the RFID tag allows reading of necessary data only when the same authentication information as the stored authentication information is input. .

In addition, when the RFID tag stores at least two pieces of data that require authentication, each piece of data requires unique authentication information. In this way, each radio recognition tag allows only reading of the corresponding data when authentication information is input.

In addition, when at least two RFID readers using the same radio resource read data, the two RFID readers may collide with each other. That is, by using the same radio resource, two radio readers may fail to read data due to collision between the read data. Therefore, the radio reader needs to notify the user that such a case has occurred.

The notification unit 212 notifies the user of the detected unusual operation. According to FIG. 2, the notification unit 212 includes a display unit 208 and a sound generator 210. However, other configurations other than the display unit 208 and the voice generator 210 may be included in the notification unit 212. That is, the vibration unit for notifying the detected special movement by vibration may be included in the notification unit 212.

The display unit 208 displays information corresponding to the unusual operation according to the control command. That is, the display unit 208 displays information corresponding to the unusual operation as one information or unique information corresponding to the unusual operation. That is, the user sets an identification number corresponding to the information corresponding to each unusual operation in order to briefly display the information corresponding to the unusual operation. When the unusual operation occurs, the display unit 208 displays an identification number corresponding to the generated unusual operation. Table 1 shows outliers and identification numbers corresponding to outliers.

Unusual behavior Identification number When to read data of radio tag A When to record data of received RFID tag B Successful reading of RFID tag data C Failed to read radio tag data D Successful recording of received RFID tag data E Failure to record received RFID tag data F When a collision occurs with a radio reader using the same radio resources in the vicinity G When authentication information is required to read data from the RFID tag H

Of course, the display unit 208 may display the unusual operation generated in various ways to the user.

Like the display unit 208, the voice generator 210 generates a constant voice to notify the user that an unusual operation has occurred according to a control command. In this case, the voice generator 210 notifies the user with one voice regardless of the type of the singular motion, or notifies the user that the singular motion has occurred with a unique voice according to the type of the singular motion.

In FIG. 2, only a method of notifying a user that an unusual operation has occurred is visually indicated by the display unit 208 or an audible method by the voice generator 210. However, in addition to the above-described methods, it can be notified that the unusual operation has occurred in a tactile manner through vibration of the radio reader. Of course, the user may be notified that the unusual operation has occurred by other methods besides the above-described methods.

The control unit 200 controls the operation of the devices constituting the radio reader. That is, the controller 200 controls the operation of the signal processor 204 to process the received signal, or controls the operation of the singular motion detector 206 to detect the singular motion. In addition, the controller 200 notifies the user that the abnormal operation is detected by controlling the operation of the display unit 208 and the voice generator 210 when the abnormal operation is detected. In this case, the controller 200 may notify the user of the occurrence of the unusual operation, and then display or transmit a voice at regular intervals until it becomes separate information from the user. By doing so, the radio reader can accurately notify the user that an unusual operation has occurred.

The constant interval can be set differently according to the type of singular motion. That is, when authentication information is required, a predetermined interval may be set short for data reading failure, and the like, and a predetermined interval may be set for long when data reading is successful.

3 illustrates the operation of a wireless reader according to an embodiment of the present invention. Hereinafter, the operation of the radio reader according to an embodiment of the present invention will be described in detail with reference to FIG. 3.

In step S300 the wireless recognition reader sets the information corresponding to the unusual operation. According to the above, the time point at which the data of the radio recognition tag is read, the time point at which the data of the received radio recognition tag is recorded, the success or failure of reading the radio recognition tag data, the success or failure of recording the received radio recognition tag data, and the surroundings When there is a collision with the radio reader using the same radio resource, the authentication operation is required to read the data of the radio tag and the like is included in the unusual operation. Of course, in addition to the above-described cases it is necessary to notify the user of the operation state of the wireless recognition lead is a special operation. Of course, other cases other than the above-described case may be included in the unusual operation.

In step S302, the radio recognition reader performs an operation. That is, the RFID reader transmits radio waves to the RFID tag to read data stored in the RFID tag.

In step S304, the wireless recognition reader determines whether or not the set unusual operation has occurred. If the set unusual operation has occurred, the wireless recognition reader moves to step S306, and if the unusual operation does not occur, moves to step S308 and ends.

In step S306, the wireless recognition reader notifies the user of the generated unusual operation. That is, the wireless recognition reader may display that the abnormal operation has occurred on the display unit or notify the user by using voice. Alternatively, the radio reader may notify the user by vibrating the radio reader when an unusual operation occurs. Of course, different vibration methods may be used for the type of singular motion generated.

As described above, the present invention notifies the user of the unusual operation of the radio reader, so that the user can accurately recognize the operation state of the radio reader. In addition, the wireless recognition reader notifies the user of his state, so that the user does not need to perform an unnecessary operation for recognizing the operating state of the wireless recognition reader. This results in improved concentration of the user. In addition, the wireless recognition reader transmits its operation failure state to the user, the user can heal the failure state of the wireless recognition reader.
