DETAILED DESCRIPTION
[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0034] See also Figure 1 , Figure 1 This is a structural block diagram of an RFID tag reader provided in an embodiment of the present application, wherein the RFID tag reader comprises: a first antenna 1, a host 2, a second antenna 3, a connecting rod 4 connecting the first antenna 1 and the host 2, and a rotating shaft 5 connecting the second antenna 3 and the host 2; the size of the first antenna 1 is smaller than the size of the second antenna 3.
[0035] In the embodiment of the present application, the first antenna 1, the connecting rod 4, the host 2, the rotating shaft 5 and the second antenna 3 are connected in sequence, and the second host 2 and the second antenna 3 can be rotated through the rotating shaft 5, so as to facilitate the storage of the second antenna 3. The RFID tag reader can meet the maintenance requirements of ODN (Optical Distribution Network, optical distribution network), is convenient for users to carry and use, and users do not need to carry two RFID tag readers, while saving the purchase cost of RFID tag readers.
[0036] In an optional embodiment, an angle is formed between the second antenna 3 and the host 2;
[0037] When the angle is less than or equal to the preset angle, the first antenna 1 is in working state, and the second antenna 3 is not in working state;
[0038] When the included angle is greater than the preset angle, the first antenna 1 is not in a working state, and the second antenna 3 is in a working state.
[0039] In the embodiment of the present application, the second host 2 and the second antenna 3 are rotated by the rotation axis 5, so that an angle is formed between the second antenna 3 and the host 2.
[0040] When the angle is less than or equal to the preset angle, it means that the second antenna 3 and the host 2 are in a folded state. At this time, the first antenna 1 can be set to be in a working state, and the second antenna 3 can be set to be in a non-working state; when the angle is greater than the preset angle, it means that the second antenna 3 and the host 2 are not in a folded state. At this time, the first antenna 1 can be set to be in a non-working state, and the second antenna 3 can be set to be in a working state.
[0041] The embodiment of the present application switches the working states of the first antenna 1 and the second antenna 3 by folding or unfolding the second antenna 3 and the host 2, thereby avoiding the first antenna 1 and the second antenna 3 from working at the same time to cause interference and reduce power consumption.
[0042] In an optional embodiment, if Figure 2 , the host 2 includes a main control module 21, a radio frequency transceiver module 22 and a switching module 23 connected in sequence;
[0043] The switching module 23 has a first fixed end, a second fixed end, a first movable end, a second movable end, a third movable end and a fourth movable end; the first fixed end is connected to the first RF channel of the RF transceiver module 22, the second fixed end is connected to the second RF channel of the RF transceiver module 22, the first movable end is connected to the first antenna 1, and the fourth movable end is connected to the second antenna 3; the RF signal power of the first RF channel is less than the RF signal power of the second RF channel;
[0044] The main control module is used to control the switching module 23 to switch between the first state and the second state;
[0045] In the first state, the first fixed end is connected to the first movable end, and the second fixed end is connected to the third movable end, so that the first antenna 1 is in a working state, and the second antenna 3 is not in a working state;
[0046] In the second state, the first fixed end is connected to the second movable end, and the second fixed end is connected to the fourth movable end, so that the first antenna 1 is not in a working state, and the second antenna 3 is in a working state.
[0047] In an embodiment of the present application, the RF transceiver module 22 is responsible for processing RF signals and transmitting data, and has two RF channels. The RF signal of the first RF channel flows into the first fixed end, and the RF signal of the second RF channel flows into the second fixed end. The RF signal power of the first RF channel is less than the RF signal power of the second RF channel to meet the working requirements of the first antenna 1 and the second antenna 3.
[0048] In the embodiment of the present application, the switching module 23 is controlled to switch between the first state and the second state, thereby switching the working states of the first antenna 1 and the second antenna 3.
[0049] Exemplarily, the switching module 23 may be two single-pole double-throw switches; one single-pole double-throw switch has a first fixed end, a first movable end, and a second movable end; the other single-pole double-throw switch has a third movable end and a fourth movable end. The switching module 23 may be a double-pole double-throw switch, which has two connection states. When switching upward, the first fixed end is connected to the first movable end, and the second fixed end is connected to the third movable end; when switching downward, the first fixed end is connected to the second movable end, and the second fixed end is connected to the fourth movable end.
[0050] In an optional embodiment, the radio frequency transceiver module 22 includes: a radio frequency transceiver unit 221 and a power divider 222;
[0051] The first end of the RF transceiver unit 221 is connected to the main control module 21, the second end of the RF transceiver unit 221 is connected to the first end of the power divider 222, the second end of the power divider 222 is connected to the first RF channel, and the third end of the power divider 222 is connected to the second RF channel.
[0052] In the embodiment of the present application, the power divider 222 is responsible for dividing one RF signal output by the RF transceiver unit 221 into two RF signals with different powers, so that the two RF signals flow into the first fixed end and the second fixed end respectively through different RF channels.
[0053] In an optional embodiment, the RF transceiver module 22 includes: a first RF transceiver unit 223 and a second RF transceiver unit 224; the first RF transceiver unit 223 is connected to the first RF channel, and the second RF transceiver unit 224 is connected to the second RF channel.
[0054] For example, Figure 3-Figure 4 The switching module 23 is a double-pole double-throw switch, which has two connection states. When switching upward, the first fixed end a is connected to the first movable end c, and the second fixed end b is connected to the third movable end e; when switching downward, the first fixed end a is connected to the second movable end d, and the second fixed end b is connected to the fourth movable end f.
[0055] In an optional embodiment, if Figure 5 The host 2 further includes: a touch switch 24, and when the angle is less than or equal to the preset angle, the touch switch 24 is triggered.
[0056] In the embodiment of the present application, the host 2 further includes: a touch switch 24, so that when the second antenna 3 / the host 2 rotates around the rotation axis 5 until the angle between the second antenna 3 and the host 2 is less than or equal to the preset angle, the touch switch 24 is triggered, and at this time the main control module 21 can control the first antenna 1 to be in a working state, and the second antenna 3 is not in a working state. When the touch switch 24 is not triggered, it means that the angle is greater than the preset angle. At this time, the main control module 21 can control the first antenna 1 to be out of a working state, and the second antenna 3 to be in a working state.
[0057] Exemplarily, a spring is provided in the touch switch 24. When the angle is less than or equal to the preset angle, the spring is squeezed by the host 2 / second antenna 3 / rotating shaft 5. At this time, the touch switch 24 is triggered to generate a trigger signal. When the main control module 21 receives the trigger signal, it controls the first antenna 1 to be in a working state, and the second antenna 3 to be not in a working state.
[0058] Exemplarily, a metal spring is provided in the touch switch 24. When the angle is less than or equal to the preset angle, the metal spring is moved, i.e., the touch switch 24 is triggered, so that the metal spring is switched to connect with the first antenna 1, so that the main control module 21 is connected with the first antenna 1, so that the main control module 21 controls the first antenna 1 to be in a working state, and the second antenna 3 is not in a working state.
[0059] Exemplarily, an angle sensor is provided in the touch switch 24, which detects the size of the angle. When the angle is less than or equal to the preset angle, the touch switch 24 is triggered. At this time, the main control module 21 can control the first antenna 1 to be in a working state, and the second antenna 3 to be not in a working state.
[0060] The touch switch 24 can be installed at any position of the host 2, the second antenna 3 or the rotating shaft 5, and is not specifically limited here. It only needs to satisfy that when the angle is less than or equal to the preset angle, the touch switch 24 is triggered.
[0061] In an optional embodiment, the size of the first antenna 1 is: 3mm*3mm~7mm*7mm; the size of the second antenna 3 is: 30mm*30mm~70mm*70mm.
[0062] In the embodiment of the present application, the first antenna 1 is a miniature antenna, and the second antenna 3 is a common near-field antenna. By setting two antennas in one RFID tag reader, users do not need to carry two RFID tag readers, which is convenient for users to carry and use, and saves the purchase cost of the RFID tag reader.
[0063] In an optional embodiment, the host 2 is provided with a receiving slot, and the second antenna 3 can be received in the receiving slot by rotating the rotating shaft 5 .
[0064] In the embodiment of the present application, by rotating the rotating shaft 5, the second antenna 3 can be folded into the receiving slot of the host 2 for storage. Optionally, as Figure 6 The receiving slot is arranged on the back of the host 2 so as not to affect the use of the display screen arranged on the front of the host 2.
[0065] In an optional embodiment, the first antenna 1 is used to collect identification information of a first type of tag; and the second antenna 3 is used to collect identification information of a second type of tag.
[0066] It is understandable that there are various types of labels in the junction box. To facilitate label management, labels for different purposes are classified and managed, and the classification information is written into the EPC area of the label. For example, the classification information is ODF port label, fiber jumper label and optical cable label.
[0067] The embodiment of the present application can set the RFID tag reader to: when the first antenna 1 is working, only the identification information of the first type of tags, such as the identification information of the ODF port tag, is collected; when the second antenna 3 is working, only the identification information of the second type of tags, such as the identification information of the jumper fiber and the optical cable label, is collected.
[0068] In this way, when collecting ODF port labels in the junction box, the RFID tag reader switches to the first antenna 1 to work. At this time, even if the first antenna 1 receives interference from the radio frequency signals reflected by other tags such as jumper tags, since the category information in the EPC area of other tags is inconsistent with the category information of the ODF port label, the first antenna 1 can eliminate the interference and correctly collect the identification information of the read ODF port label, thereby improving the accuracy of label identification information collection.
[0069] In an optional embodiment, if Figure 5 The host 2 also includes: a position detection module 25, which is used to detect the position of the RFID tag reader, and the position of the RFID tag reader is used to instruct the terminal or the RFID tag reader to open the corresponding application in combination with the working status of the first antenna and the working status of the second antenna.
[0070] In the embodiment of the present application, the position of the RFID tag reader is detected by adding a position detection module 25, and the corresponding application of the terminal or the RFID tag reader is opened by combining the position of the RFID tag reader, the working state of the first antenna 1 and the working state of the second antenna 3. Optionally, the position detection module 25 includes at least one position sensor.
[0071] Exemplarily, when the RFID tag reader is located at a junction box, the first antenna 1 is in working condition, and the second antenna 3 is not in working condition, the terminal or RFID tag reader opens an application related to ODF tag collection; when the RFID tag reader is located at an optical cable pole or a hand hole, the first antenna 1 is not in working condition, and the second antenna 3 is in working condition, the terminal or RFID tag reader opens an application corresponding to optical cable resource management. The embodiment of the present application is combined with the position detection module 25 to automatically open the corresponding application of the terminal or RFID tag reader in different scenarios, which is convenient to use and improves the convenience of application access to the cloud resource management system.

[0073] When the first antenna 1 is in working state and the second antenna 3 is not in working state, the forward direction of the content displayed by the display module 26 is toward the first antenna 1;
[0074] When the first antenna 1 is not in a working state and the second antenna 3 is in a working state, the forward direction of the content displayed by the display module 26 faces the second antenna 3 .
[0075] In the embodiment of the present application, the orientation of the content displayed by the display module 26 is dynamically set according to the working status of the first antenna 1 and the second antenna 3, so as to facilitate the user to observe the display module 26. Optionally, the display module 26 includes at least one display screen, and the content that can be displayed by the display module 26 includes but is not limited to images, text, and numbers, and can represent information such as ODF port, battery power, wireless communication connection success / failure, and RFID tag reading success / failure.

[0079] The input / output module includes but is not limited to input / output components such as a button module 29 , an LED module 30 , an alarm module 31 , and a camera module 32 .
[0080] The key module 29 includes, but is not limited to, a power key 291, an illumination key 292, a TID key 293, a communication key 294, an RFID key 295, a side key 296 and other functional keys. The power key 291 is used to start / stop the RFID reader; the illumination key 292 is used to start / stop the illumination LED 302; the TID key 293 is used to retrieve the identification information of the RFID tag stored most recently; the communication key 294 is used to start / stop the communication function of the communication module; the RFID key 295 is used to collect the identification information of the RFID tag; the side key 296 is arranged on the side of the host 2, and its function can be set according to personal habits, such as being set to the most frequently used key function.

[0083] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
