An application database 61 is provided for storing data received and processed by the control unit 50, and providing and updating an application or software required for operation of the RFID system.

The content of the first radio frequency identification tag 20 is the same as that of the second radio frequency identification tag 30. The difference is that the detection tag 30 is fixedly disposed in a range readable by the radio frequency identification reader 10. Generally, the radio frequency is The identification reader 10 can continuously read the first radio frequency identification tag 20, and if the mobile object 40 moves and the second radio frequency identification tag 30 enters the reading range of the radio frequency identification reader 10, the radio frequency identification The reader 10 can simultaneously read the data of the first radio frequency identification tag 20 and the second radio frequency identification tag 30, and when the mobile object 40 moves and the second radio frequency identification tag 30 leaves the radio frequency identification reader The radio frequency identification reader 10 can only read the first radio frequency identification tag 20 when the reading range is 10. The RFID reader 10 can continuously read the first RFID tag 20 and transmit the signal to the control unit 50, and the server 60 can pass the control unit 50 through the control unit 50. The RFID reader 10 performs an update check from time to time.

For example, the radio frequency identification reader 10 and the first radio frequency identification tag 20 are disposed at a car dealership point 100. The control unit 50, the input device 51, the display 52, and the server 60 are disposed at the remote end. The enterprise headquarters 200 can continuously read the first RFID tag 20 and transmit the read data to the control unit 50 via the network 70 when the system is in normal operation. And displaying the data on the display 52, the operator at the corporate headquarters 200 can know that the system is operating normally, and the vehicle (ie, the mobile object 40) provided with the second radio frequency identification tag 30 arrives at the car dealership point, and is When the reading range of the RFID reader 10 is sent, the RFID reader 10 can simultaneously read the first RFID tag 20 and the second RFID tag 30, and the read data is The network 70 is transmitted to the control unit 50 for comparison. For example, the first RFID tag 20 is for an A-brand vehicle, and the first RFID tag 20 stores information about the model and specifications of the A-brand vehicle. The information stored in the second RFID tag 30 is also for the A-branded vehicle, and the model, specifications, and the like of the A-branded vehicle, if the first RFID tag 20 and the second RFID tag 30 are compared. The data conforms to represent that the mobile object 40 is a vehicle required for the automobile dealership, and the monitoring personnel or supervisor at the company headquarters 200 can immediately know the information that the vehicle arrives at the distribution point; it must be noted that the radio frequency identification reader The first radio frequency identification tag 20 is continuously read while the second radio frequency identification tag 30 is being read. The update time of the radio frequency identification reader 10 by the server 60 can be set by the control unit 50 to be a certain period of time. For example, 10 seconds or 20 seconds, and record the update time.

Please refer to the first figure and the second figure at the same time to illustrate the monitoring method flow 300 of the radio frequency identification monitoring system of the present invention, which includes the following steps:

Step 301: Perform at least one network connection with the radio frequency identification reader 10 by the control unit 50, and determine whether the network connection is successful (step 3011), if the control unit 50 and the network of the radio frequency identification reader 10 If the connection of the line 70 fails, a first maintenance process is performed. If the connection between the control unit 50 and the network 70 of the RFID reader 10 is successful, then a subsequent step 302 is performed. In order to confirm whether the network 70 can not be connected, the control unit 50 and the RFID reader 10 can be connected to the network multiple times, when the control unit 50 and the RFID reader 10 are in the first network. After the connection fails, the second network connection is performed after a set period of time (for example, two minutes). If the second network connection is successful, step 302 is performed, if the second network is used. If the connection fails, the first maintenance process 400 is entered, and the user can set the number of times the network 70 is connected and the time of repeated connection.

Referring to the third figure, a first maintenance process 400 of the present invention is illustrated, which includes the following steps:

Step 401: Check whether the radio frequency identification reader 10 is in a power-on state. If the radio frequency identification reader 10 is in a non-power-on state, the radio frequency identification reader 10 is turned on (step 4011), so that the radio frequency identification reader 10 is turned on (step 4011). The RFID reader 10 is in a power-on state. If the RFID reader 10 is in a power-on state, a subsequent step 402 is performed.

Step 402: Check whether the network 70 connection between the control unit 50 and the radio frequency identification reader 10 is normal. If the network 70 connection is abnormal, the maintenance network 70 is connected to the normal connection state (step 4021). If the network 70 connection is normal, the step of reading the data of the first RFID tag 20 by the RFID reader 10 is performed at least once (step 302 shown in the second figure).

There are two main maintenance items of the first maintenance process 400, one is for the power-on state of the RFID reader 10, and the other is for the connection state of the network 70, because the two reasons are caused by step 301. The main reason that the control unit 50 and the radio frequency identification reader 10 cannot be connected to the network is that the control unit 50 and the network 70 of the radio frequency identification reader 10 can be smoothly connected and stored after the completion of the above two inspections. In addition, users can add other maintenance items as needed.

Step 302: The radio frequency identification reader 10 reads the data of the first radio frequency identification tag 20 at least once, and determines whether the radio frequency identification reader 10 can read the data of the first radio frequency identification tag 20 (steps) 3021), if the RFID reader 10 cannot read the data of the first RFID tag 20, perform a second maintenance process 500, if the RFID reader 10 can read the first RFID tag For the information of 20, proceed to step 303.

Referring to the fourth figure, a second maintenance process 500 of the present invention is illustrated, which includes the following steps:

Step 501: Check whether the first radio frequency identification tag 20 is faulty. If the first radio frequency identification tag 20 is faulty, replace or repair the first radio frequency identification tag 20 (step 5011), if the first radio frequency identification tag 20 is not faulty. Then proceed to the next step 502.

Step 502: Check whether the reader antenna (not shown) that reads the first RFID tag 20 is loose. If the antenna is loose, check the antenna to the normal connection state (step 5021). If the antenna connection is normal, then The step of reading the data of the second radio frequency identification tag 30 by the radio frequency identification reader 10 (step 303 shown in the second figure) is performed.

The second maintenance process 500 has two main maintenance items, one is for whether the first RFID tag 20 is faulty, and the other is for the reader antenna that reads the first RFID tag 20 is loose, because the two The reason is that the main reason that the radio frequency identification reader 10 cannot read the first radio frequency identification tag 20 in step 302 is that the radio frequency identification reader 10 can smoothly read the first condition after the completion of the above two maintenance operations. In addition to the RFID tag 20, the user can also add other maintenance items as needed.

Step 303: The radio frequency identification tag 10 reads the data of the second radio frequency identification tag 30. If the second radio frequency identification tag 30 is not read, the second radio frequency identification tag 30 has not entered the radio frequency identification. Within the reading range of the reader 10, steps 301, 302 are repeated until the second radio frequency identification tag 30 is read; if the second radio frequency identification tag 30 has entered the reading range of the radio frequency identification reader 10 However, it cannot be read by the RFID reader 10. If the second RFID tag 30 fails, the second RFID tag 30 can be directly repaired.

Step 304: The control unit 50 receives and processes the data of the radio frequency identification tag read by the radio frequency identification reader 10 via the network 70. The radio frequency identification reader 10 depends on the radio frequency identification tag in the reading range. If the radio frequency identification reader 10 has only the first radio frequency identification tag 20 in the reading range, the control unit 50 can receive and process the data of the first radio frequency identification tag 20 via the network 70, if the radio frequency identification tag is read. The first radio frequency identification tag 20 and the second radio frequency identification tag 30 are in the reading range of the device 10, and the control unit 50 can receive and process the first radio frequency identification tag 20 and the second radio frequency identification tag via the network 70. 30 information.

Step 305: The control unit 50 and the server 60 perform at least one network connection, and determine whether the network connection is successful (step 3051), if the control unit 50 fails to connect to the network 80 of the server 60. Then, a third maintenance process 600 is performed. If the control unit 50 is successfully connected to the network 80 of the server 60, the control unit 50 transmits and stores the read data of the second RFID tag 30. The application database 61 of the server 60 is located (step 3052). In order to confirm whether the network 80 cannot be connected, the control unit 50 and the server 60 may perform multiple network connections. When the control unit 50 fails the first network connection with the server 60, Then, after a set period of time (for example, two minutes), the second network connection is performed. If the second network connection is successful, the second radio frequency identification tag read by the control unit 50 The data of 30 is transmitted and stored in the server 60, and if the second network connection fails, the third maintenance process is entered.

Referring to the fifth figure, a third maintenance process 600 of the present invention is illustrated, which includes the following steps:

Step 601: Check whether the network 80 connection between the control unit 50 and the server 60 is normal. If the network 80 connection is abnormal, the maintenance network 80 is connected to the normal connection state (step 6011). If the network 80 is connected properly, the control unit 50 transmits and stores the read data of the second RFID tag 30 to the server 60, and the step 305 is completed.

In addition, the radio frequency identification monitoring system (shown in FIG. 1 ) provided by the present invention may be provided with a warning device 53 , which may be connected to the control unit 50 , and the control unit 50 and the radio frequency identification reader 10 . The network 70 fails to connect, or the RFID reader 10 cannot read the data of the first RFID tag 20, or the control unit 50 fails to connect to the network 80 of the server 60, the alert The device 53 can issue an alert signal. For example, the display device 52 can send a text signal, or an acousto-optic device such as an alarm bell can be alerted to enable the administrator to quickly know the system abnormality.

In summary, the radio frequency identification monitoring system and the monitoring method provided by the present invention set a radio frequency identification tag for detecting in the radio frequency identification monitoring system as a basis for quickly detecting system errors, thereby simplifying the debugging process and reducing the detection. The purpose of the wrong time, and its system architecture is simple, can be attached to the original RF identification monitoring system.

However, the above is only an embodiment of the present invention, and the scope of the present invention cannot be limited thereto; in addition to the above-mentioned vehicle delivery status monitoring, it can also be applied to parking lot entry and exit vehicle management, or other item tracking management. Etc., any RF identification system can be applied. That is to say, the equivalent changes and modifications made by the applicant in accordance with the scope of the patent application of the present invention should still fall within the scope of the patent of the present invention. I would like to ask your review committee to give a clear explanation and pray for it.
