Referring to fig. 1 and fig. 2, the present invention provides a method for detecting different verification states of a radio frequency identification device, the method comprising the following steps:

referring to fig. 3 to 5, S1: turning on a first verify state: the radio frequency antenna 1 is electrically connected between the two conducting connecting ends 42 of the two first conductive clamping elastic moving pieces 401, when the two conductive contact parts 41 of the radio frequency antenna 1 touch the two access ends of the first radio frequency circuit, the first radio frequency circuit is electrically connected and conducted with the radio frequency antenna 1 to form a first verification state, and the first verification state can be identified by an external reading device matched with the first verification state;

referring to fig. 7, S2: disconnecting the first verification state, when the two stressed inclined planes 411 of the two first conductive clamping elastic moving pieces 401 are subjected to an oblique acting force exerted by the second radio frequency conducting piece 3, the two conductive contact parts 41 are separated from the two access ends of the first radio frequency circuit and support the second radio frequency conducting piece 3, so that the first radio frequency circuit is disconnected from the radio frequency antenna 1, and the second radio frequency conducting piece 3 is located between the first radio frequency conducting piece 2 and the two first conductive clamping elastic moving pieces 401;

referring to fig. 6 again, the first conductive clamping elastic moving member 401 has an elastic function, and a force-receiving inclined surface 411 is formed at one end of the first conductive clamping elastic moving member 401, when the force-receiving inclined surface 411 receives an oblique acting force, the first conductive clamping elastic moving member 401 can be bounced, and when the oblique acting force is removed, the first conductive clamping elastic moving member 401 can be bounced back towards the original position;

referring to fig. 8 to 11, S3: switching to a second verify state: the second rf conductive member 3 is provided with a second rf circuit, and the access end thereof is disposed on the surface of the second rf conductive member, when the two conductive contact portions 41 of the two first conductive clamping elastic moving members 401 slide to the two access ends of the second rf circuit and contact with the second rf circuit, the second rf circuit is electrically connected to the rf antenna 1 to form a second verification state, and can be identified by an external reading device matched with the second rf circuit.

In the technical scheme of the invention, the conductive clamping elastic moving part 4 connects and disconnects the radio frequency antenna 1 with and from the circuit in the first radio frequency conducting part 2 or the second radio frequency conducting part 3, and the radio frequency antenna and the circuit are respectively read by using external reading and writing equipment matched with the radio frequency antenna, and the locking device or the equipment can be judged to be in a first verification state according to the obtained first radio frequency circuit; or the locking device or the equipment can be judged to be in the second verification state by acquiring the second radio frequency circuit information, the external read-write equipment does not read the first radio frequency circuit or the second radio frequency circuit information, and the locking device or the equipment can be judged to be in the first verification state or the second verification state for detection. The front of the deep-entering end of the second radio frequency conducting piece 3 is also an inclined plane, so that the second radio frequency conducting piece 3 can slide conveniently, and the resistance is reduced.

The verification state can be a locking state, for example, the first verification state is that the locking device is unlocked or unlocked, the second verification state is that the locking device is in the locking state, the state of the locking device is obtained, so that whether bags, boxes and the like with the locking device are locked or unlocked can be known, the full goods and the empty goods are judged during checking, and the operation is simple; the system can also be used for prompting, for example, when the garage is in the first verification state, the garage is still provided with a vacant position, and when the garage is in the second verification state, the garage is checked by personnel without getting off the vehicle, and information is directly read on the vehicle or voice prompt information is obtained.

Radio Frequency (RF) is an abbreviation for Radio Frequency, which refers to an electromagnetic Frequency that can radiate into space, ranging from 300KHz to 300 GHz. The short term Radio Frequency (RF) is radio frequency current, which is a short term for high frequency Alternating Current (AC) variable electromagnetic wave. Alternating current that changes less than 1000 times per second is called low frequency current, and alternating current that changes more than 10000 times per second is called high frequency current, and radio frequency is such a high frequency current. High frequency (greater than 10K); the radio frequency (300K-300G) is a higher frequency band of high frequency; the microwave band (300M-300G) is again the higher frequency band of radio frequencies. In the theory of electronics, current flows through a conductor, and a magnetic field is formed around the conductor; an alternating current passes through a conductor, around which an alternating electromagnetic field, called an electromagnetic wave, is formed. When the frequency of the electromagnetic waves is lower than 100kHz, the electromagnetic waves can be absorbed by the earth surface and cannot form effective transmission, but when the frequency of the electromagnetic waves is higher than 100kHz, the electromagnetic waves can be transmitted in the air and reflected by an ionosphere at the outer edge of the atmosphere to form long-distance transmission capability, and the high-frequency electromagnetic waves with the long-distance transmission capability are called radio frequency; radio frequency technology is widely used in the field of wireless communications.

The method is based on the RFID radio frequency technology, the RFID radio frequency technology comprises an active RFID radio frequency technology and a passive RFID radio frequency technology, the passive RFID radio frequency technology can be adopted in the embodiment, electricity is saved, and particularly for some use places of strictly controlled electricity, such as bank storage, warehouse and the like, the passive RFID radio frequency technology is adopted for preventing fire. Of course, in some embodiments, active RFID radio frequency technology may also be used, which can increase signal transmission distance, etc. In the present invention, the rf antenna circuit and the rf IC chip connected to the rf circuit or the rf IC chip of the circuit board are all matched with each other, and the description thereof is omitted below.

The number of the radio frequency circuits arranged in the first radio frequency conducting piece 2 is one, for example, the first radio frequency circuits, and may also be two, or more than two, such as 3, 4, 5, 6, 7, 8, etc., where the number of the first radio frequency IC chips 21 is at least one, and certainly may also be two, three, or more than three, such as 4, 5, 6, 7, etc., and when the first verification state is formed, the external reading device can read information in the first radio frequency IC chips 21;

the number of the radio frequency circuits arranged in the second radio frequency conducting piece 3 is one, for example, the second radio frequency circuit, and may also be two, or more than two, for example, 3, 4, 5, 6, 7, 8, etc., where the number of the second radio frequency IC chip 31 is at least one, and certainly may also be two, three, or more than three, for example, 4, 5, 6, 7, etc., and when the second verification state is formed, the external reading device can read information in the second radio frequency IC chip 31.

Referring to fig. 10, the first radio frequency conducting member 2 and the second radio frequency conducting member 3 may be a circuit board, an RFID electronic seal, and various shapes of parts/structures provided with radio frequency circuits, for example, the first radio frequency conducting member 2 is a circuit board, the second radio frequency conducting member 3 is an RFID electronic seal, the second radio frequency conducting member 3 realizes disconnection of the first radio frequency circuit and conduction of the second radio frequency circuit by being inserted between the first radio frequency conducting member 2 and the conductive clamping elastic moving member 4, and further realizes the locking state in the process of converting the unlocking/unlocking state of the locking device into locking state.

Referring to fig. 11 and 12, the number of the conductive clamping elastic moving members 4 is at least two, such as two first conductive clamping elastic moving members 401, the number of the conductive clamping elastic moving members 4 may be two, or more than two, such as 3, 4, 5, 6, 7, 8, 9, 10, or more than 10, and the like, and the plurality of conductive clamping elastic moving members 4 are elastically mounted on the mounting member 5, referring to fig. 2. A plurality of electrically conductive chucking elastic movement pieces 4 can be arranged side by side in installed part 5, and vertical row or horizontal row or both cases have promptly, also can array arrangement, or alternately arrange, design number and mode of arranging as required. The shape and size of the mounting member 5 are designed as required, such as a circle, a bar, a plate, a square, an irregular shape, etc. In fig. 2 and 17, which only illustrate two cases, the first conductive elastic moving member 401 and the second conductive elastic moving member 402 may not be arranged side by side, for example, the first conductive elastic moving member 401 and the second conductive elastic moving member 402 have a certain space therebetween, and one or more conductive elastic moving members 4 are arranged therebetween for separation. Because the conductive clamping elastic moving piece 4 has an elastic function, the conductive clamping elastic moving piece is disconnected with the first radio frequency circuit access end in the first radio frequency conduction piece 2 and is connected with the second radio frequency circuit access end in the second radio frequency conduction piece 3 to realize the conduction of the locking circuit or the conduction and disconnection of other radio frequency circuits.

Referring to fig. 12 and 13, the conductive clamping elastic moving member 4 has an elastic function, because one end of the conductive clamping elastic moving member 4, which is used for being connected with an external connecting member, is connected with the mounting member 5 through an elastic structure, such as a compression spring 6. It will be appreciated that the conductive gripping resilient movement element 4 may itself have a resilient function, such as a spring tab or the like. In the process that the locking device forms a locking state, one end of the second radio frequency conducting piece 3 slides forwards along and presses the two stressed inclined planes 411 of the at least two first conductive clamping elastic moving pieces 401 to the process that the two conductive contact parts 41 of the at least two first conductive clamping elastic moving pieces 401 are conducted with the two access ends of the second radio frequency circuit, and the first conductive clamping elastic moving pieces 401 are bounced under the oblique acting force applied by the second radio frequency conducting piece 3, so that the first conductive clamping elastic moving pieces 401 have elastic potential energy or the elastic potential energy is increased; when the second radio frequency conducting part 3 is separated from the top holding surface of the first conductive clamping elastic moving part 401, the oblique acting force is instantaneously removed to enable the first conductive clamping elastic moving part 4 to rebound to the original position under the action of elastic potential energy or rebound towards the original position to abut against the surface of the other part of the second radio frequency conducting part 3 blocking the rebound, if a concave groove is formed at the part where the second radio frequency conducting part 3 and the conductive clamping elastic moving part 4 slide relative to each other, the first conductive clamping elastic moving part 401 and the sliding end of the part further rebound, and if the groove is a through hole, the end is changed to pass through the through hole to the original position under the action of elastic force. The relative movement between the second rf conducting member 3 and the first conductive elastic clamping moving member 4 can be a linear movement or a curved movement, such as an S-shaped curved movement.

The oblique acting force is acting on the stressed inclined plane of the conductive clamping elastic moving part 4, so that the conductive clamping elastic moving part can bounce relative to the first radio frequency conducting part 2, and bounce is the movement away from the first radio frequency conducting part 2. After the conductive clamping elastic moving part 4 bounces, the second radio frequency conducting part 3 can slide forward along the stress inclined plane 411, and after the conductive clamping elastic moving part slides across the stress inclined plane 411, one end of the conductive clamping elastic moving part 4 or the conductive contact part 41 props against the surface of the second radio frequency conducting part 3. The front of the deep-entering end of the second radio frequency conducting piece 3 is also an inclined plane, so that the second radio frequency conducting piece 3 can slide conveniently, and the resistance is reduced.

The access ends arranged on the surfaces of the first radio frequency conducting piece 2 and the second radio frequency conducting piece 3 can conduct electricity and are used for being electrically connected with a circuit in the corresponding radio frequency conducting piece, the surfaces of the first radio frequency conducting piece 2 and the second radio frequency conducting piece 3 occupy certain surface areas, and the surfaces of the access ends are preferably planes or curved surfaces and are designed according to use requirements. The access end has certain length, can guarantee that the second radio frequency switches on 3 inserts or withdraws from the gliding in-process of inserting the space, and the circuit still is in the conducting state, and carries out the transmission of different signals, and the space of inserting is the space that forms between first radio frequency switches on 2 and the electrically conductive chucking elastic movement piece 4. The surface of the exposed outside of the access end is a conductive contact surface (not marked), and the conductive contact of the access end is in contact with the conductive clamping elastic moving piece 4 to realize the connection and the communication of two circuits. The length of the access tip may be greater than 0mm and less than or equal to 200mm, such as dimensions of 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 150mm, 160mm, 190mm, and the like. Of course the access end can also be of a design larger than 200 mm.

In the present invention, an antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space) or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all use electromagnetic waves to transmit information and work by depending on antennas. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. The antennas are generally reciprocal in that the same pair of antennas can be used as both transmit and receive antennas. The same antenna is the same as the basic characteristic parameter for transmission or reception. At present, the antenna is more and more widely applied, the anti-interference requirement is more and more strict, and the design types are diversified. Such as a radio frequency antenna 1 used in RFID electronic tags or labels, to be widely used in the field of logistics. It can store data related to merchandise, credit cards, access cards, and vehicle control in RF. The radio frequency antenna 1 is matched with a radio frequency IC chip in the RFID electronic seal, and an RFID reader matched with the radio frequency antenna 1 reads information in the radio frequency IC chip. The RFID electronic seal can also be applied to the locking device, and when the locking device is in a locking state, the radio frequency IC chip can be read. The ideal antenna does not consider the feeding part, but in order to extract signals, the extracted point is called the feeding part, the english is expressed by feedpoint, the field distribution of the antenna is generally influenced by the addition of the feeding part, and the selection of the point is also exquisite. In the invention, the conducting connection end of the conductive clamping elastic moving piece 4 is directly connected with the feed part of the radio frequency antenna 1 or the circuit of the radio frequency antenna 1.

The circuit is a conductive loop consisting of a metal wire and electrical and electronic components, and is called a circuit. When the circuit is connected, the circuit can work by generating current, the circuit can work by an external power supply, and the circuit can work by generating current by an RFID technology.
