After the inductively coupled radio frequency device is selected as the identification device, it is desirable to select an inductively coupled radio frequency device with high reading accuracy. According to the characteristics of the inductive coupling type radio frequency element, the reading precision is influenced by three factors of the cross section shape, the size and the shell material of the radio frequency element antenna. And selecting the model in the radio frequency element provided by the manufacturer by using an orthogonal decomposition method.

The resonance characteristic graph of the inductively coupled rf element is shown in fig. 2, and it can be seen from the resonance characteristic graph that the maximum value I0 of the current appears at the resonance point ω 0, i.e. at the corresponding frequency 125kHz, the current is attenuated as long as the current deviates from the resonance angular frequency, and the degree of attenuation depends on the quality factor Q of the circuit. Namely: the large Q circuit has good selectivity; the selectivity of the Q-small circuit is poor. The orthogonal table L4(23) is selected, and an inductively coupled RF device with a high quality factor is selected.

background module (8): the door opening and closing system is used for issuing a door opening and closing task, and the scanning positioning module (5) obtains the destination result of the hand-held key and matches the hand-held key with the authorized entrance guard.

2. The controllable key door disable handheld key of claim 1, wherein said handheld key enables opening and closing of a door by:

step S1, if the base station has the hand-held key, the information that the hand-held key should open the door is set through the background module (8), and then the hand-held key is issued to the lender; if the base station has no handheld key, the scanning positioning module (5) displays a handheld key list, and selects a proper handheld key to send information for opening the door;

step S2, the hand-held key identifies the information code label (11) of the door lock through the reading module (1), and inputs the identification information into the logic module (3);

step S3, the logic module (3) receives the input signal of the reading module (1), calls the set door opening condition for comparison, and outputs a key releasing signal if the set door opening condition is met;

step S4, a driving element (602) reads a key to turn to drive a key core (601) to open the door, and the door opening state information of the door is sent to a background module (8) through a communication module (2);

and S5, returning the hand-held key when the lender does not close the door, setting the information that the door should be closed by the hand-held key by the base station through the background module (8), and returning the hand-held key after the lender is guided to return the door access control which should be closed by the display (402).

3. The controllable key door disabling handheld key of claim 2 wherein said step S5 includes the steps of:

s501, a background module (8) scans a positioning module (5) of the handheld key and loads the handheld key to a map;

step S502, the background module (8) reads historical use information of the lending time period and judges whether all doors are closed; if yes, executing step S507, otherwise executing step S503;

s503, the background module (8) sets a handheld key and sends the authorization information of the door to be closed to the corresponding handheld key;

s505, the background module (8) is connected with a handheld key to send an authorized entrance guard number;

s506, a driving element (602) reads a key to turn to drive a key core (601) to close the door, and executes the step S502 after sending the door access closing state information to a background module (8) through a communication module (2);

and step S507, after the key is used, the background module (8) is connected with the key to detect whether the key responds, if so, the operation is finished, and if not, an alarm is given.

4. The controllable key door disable handheld key of claim 1, wherein the driving member (602) is driven by a stepping motor, and when all external members satisfy the unlocking condition, the stepping motor M2 is activated to send an activation signal to the stepping motor M2 to rotate the iron sheet to release the key core, so as to open or close the door with the handheld key.

5. The controllable key door disabling handheld key of claim 1, wherein the key core (601) employs a milled slot key core and the display (402) employs a resistive touch screen.

6. Controllable key door disable handheld key according to claim 1, characterized in that the reading module (1) employs ANT513 inductively coupled radio frequency.

7. A controllable key door disablement door lock, characterized by a lock cylinder housing (9), an information code tag (11) and a lock cylinder (10) matching the key cylinder (601) of any of claims 1-6.

8. The controllable key door disable door lock according to claim 7, wherein the lock cylinder (10) is a double structure super B-class magnetic lock, and the information code tag (11) is an RFID tag.
