  In a conventional electronic lock control device, an identification number or the like registered in advance is registered in a fixed manner. Therefore, while a legitimate user continues to use the electronic lock, another person steals the electronic lock, or knows the identification number and creates the same one (joint key), and opens it without permission. There is a risk of locking or locking.

  The present invention has been made paying attention to the above-mentioned problems, and allows an owner of a key to freely update registration of an identification code, and an electronic lock control device that is not unlocked or locked by a third party without permission. It is intended to provide.

  The electronic lock control device according to the present invention includes an identification code registration unit that registers an identification code of a lock that is permitted to be operated, an identification code input unit that inputs an operator's identification code, and an input from the identification code input unit. The identification code is compared with the identification code of the identification code registration unit, and if a match is obtained, an identification code verification unit that outputs a signal indicating that, and a signal output from the identification code verification unit Receiving the lock state and the unlock state alternately, and outputting the lock signal and the unlock signal, respectively, and the input operation means for specifying and inputting the identification code registration update mode; Update registration that causes the identification code registration unit to update and register the identification code input from the identification code input unit based on the operation of the input operation means in the identification code registration update mode under the unlocked state Is provided with a control means, the.

  In this electronic lock control device, a person who is permitted to operate the lock inputs his / her identification code from the code input unit, inputs an identification code to be newly registered when unlocked, and updates the identification code registration. By operating the mode designation input operation means, the identification code newly input on the condition of the designation operation of the unlocked state and the identification code registration update mode is updated and registered in the identification code registration unit.

  In the present invention, the identification code input unit may include a key including an identification code unit and a code reading unit that reads the identification code when the key is attached.

  Further, as the identification code input unit, the identification code input unit is arranged corresponding to each key of the key having at least a pair of magnetic poles composed of N pole and S pole, and detects magnetism by attaching the key. A magnetic detection means having a magnetic detection element for detecting the presence or absence and magnetic pole of the key based on a signal of the magnetic detection means, and a means for obtaining an identification code by combining the magnetic presence / absence signal and the magnetic pole discrimination signal You may use the electronic lock which consists of.

  In the present invention, the input operation means in the identification code registration update mode may use an operation switch provided in the electronic lock control device main body case.

  Further, as the input operation means in this identification code registration update mode, it is possible to use one that determines that there is an operation by detecting that the key has been inserted at a predetermined position of the magnetic detection means for a predetermined time.

  Further, as the input operation means in this identification code registration / update mode, an apparatus that determines that there is an operation by detecting that the key is rotated to a predetermined position different from the code reading position of the magnetic detection means may be used. good.

  Further, the electronic lock control device of the present invention is inputted from the identification code registration unit for registering the identification code of the lock permitted to be operated, the identification code input unit for inputting the identification code, and the identification code input unit. The identification code is compared with the identification code of the identification code registration unit, and if a match is obtained, an identification code verification unit that outputs a signal indicating that, and a signal output from the identification code verification unit are received. A lock state / unlock state storage means for alternately storing a lock state and an unlock state and outputting a lock signal and an unlock signal, respectively, and the identification code for locking under the unlock state. When an identification code is input from the input unit, update registration control means for updating and registering the input identification code in the identification code registration unit may be provided.

  The electronic lock control device of the present invention also includes an identification code registration unit for registering an identification code of a lock that is permitted to be operated, and a locked state / unlocked state that stores whether the lock is locked or unlocked. When the state storage means, the identification code input unit for inputting the identification code, and the identification code input from the identification code input unit in the locked state are compared with the identification code of the identification code registration unit, and a match is obtained The identification code registration unit that clears the identification code registration unit and outputs an unlocking signal, and when the identification code is input from the identification code input unit to perform locking in the unlocked state, is input Update registration control means for updating and registering the identification code in the identification code registration unit.

  According to the present invention, a person who is permitted to operate, that is, an authorized key owner, operates the input operation means in the identification code registration update mode when the control device stores the unlocked state after unlocking. By doing so, a new identification code can be updated and registered in the identification code registration unit. For example, when an electronic lock is lost or used by a third party for theft, or a related party such as an employee uses the previous key. Even if they are equal, since they are old keys, no match is obtained, and unlocking / locking can be prevented.

  Further, according to the present invention, since the identification code can be updated every time locking is performed during unlocking, it is possible to prevent the third party from unlocking the system without permission.

  Hereinafter, the present invention will be described in more detail with reference to embodiments. FIG. 1 is a block diagram showing a circuit configuration of an electronic lock control device according to an embodiment of the present invention. In this embodiment, the electronic lock control device captures the identification code from the key 1 that can output the identification code, and compares the retrieved identification code with the registered identification code. It is comprised from the control apparatus main-body part 2 which outputs a locking signal or an unlocking signal.

  The key 1 used in this embodiment has a plurality of magnets, and can output an identification code signal by these magnets. The key 1 will be described in detail later. The control device main unit 2 includes a magnetic detection circuit 3, a determination circuit 4, a code setting memory 5, a comparison and matching circuit 6, a flip-flop 7, a lock signal output unit 8, a lock display unit 9, and an unlocking display. A signal output unit 10, an unlocking display unit 11, a code update switch 12, and an AND gate 13 are provided.

  The magnetic detection circuit 3 detects the magnetism of each magnet included in the key 1 when the key 1 is mounted in the vicinity. The discriminating circuit 4 discriminates the presence / absence of magnetism of the key 1 and the magnetic pole based on the magnetic detection signal from the magnetic detection circuit 3, and outputs the identification code of the key 1 based on the combination of the magnetic presence / absence signal and the magnetic pole discrimination signal. As the code setting memory 5, a nonvolatile memory such as an EEPROM is used, and an identification code of a person who permits locking / unlocking is registered in advance. The code setting memory 5 is configured to be able to update a registered identification code.

  The comparison coincidence circuit 6 takes in the identification code signal from the key 1 output from the discrimination circuit 4 and receives the registered identification code read from the code setting memory 5 as an input, and compares and collates the two. If the identification code matches, a signal indicating that is output. Each time the flip-flop 7 receives the coincidence output from the comparison coincidence circuit 6, the set / reset output is inverted. For example, if the initial state is set, the flip-flop 7 is reset when the coincidence output from the comparison coincidence circuit 6 is input. When the next coincidence signal is further input from the comparison coincidence circuit 6 in the reset state, the flip-flop 7 is set again. At the set output of the flip-flop 7, a locking signal is output from the locking signal output unit 8, and the locking display unit 9 is lit up. On the other hand, the unlock signal is output from the unlock signal output unit 10 by the reset output of the flip-flop 7 and the unlock display unit 11 is lit and displayed.

  The code update switch 12 is a switch used when the owner of the key 1 wants to update and register another new key instead of the currently used key. The AND gate 13 receives the reset output of the flip-flop, that is, the unlock signal and the operation signal of the code update switch 12. When both the input signals are combined, the output “1” is output from the determination circuit 4. The new key identification code is rewritten with the previous identification code in the code setting memory 5 to be registered and updated.

  In the electronic lock control device of this embodiment, when the owner of the key 1 unlocks the electronic lock that is locked, the key 1 is mounted on the magnetic detection circuit 3 of the control device main body 2 (for example, in FIG. 2). The key 1 is inserted into the key hole 51). The magnetic magnetism detection circuit 3 detects the magnetism of each magnet of the key 1 and outputs it to the discrimination circuit 4. The discriminating circuit 4 discriminates the presence / absence of magnetism and the magnetic pole from the magnetic detection signal from the magnetic detection circuit 3 and inputs an identification code signal based on a combination of the magnetic presence / absence signal and the magnetic pole signal to the comparison coincidence circuit 6. The comparison and coincidence circuit 6 reads the registered identification code from the code setting memory 5, compares it with the identification code input from the discrimination circuit 4, and inputs a coincidence output to the flip-flop 7 when a match is obtained. The flip-flop 7 receives the coincidence signal and is reset, and outputs an unlocking signal from the unlocking signal output unit 10 instead of the locking output. It is unlocked by this unlocking signal. If no coincidence is obtained in the comparison coincidence circuit 6, no coincidence output is produced, so that the flip-flop 7 remains in the set state, that is, in the locked state, and is not unlocked.

  In the electronic lock control apparatus of this embodiment, the key owner can perform update registration of a new key in the unlocked state. When a new key 1 a is attached to the magnetic detection circuit 3 in the unlocked state and the code update switch 12 is operated, the operation signal is input to the AND gate 13. Since the unlock signal is input to the other input terminal of the AND gate 13, both inputs of the AND gate 13 are aligned with a logic "1", and a logic "1" signal is output. The code setting memory 5 is energized by the output signal of the AND gate 13, and the new key 1a identification code from the discrimination circuit 4 is written into the code setting memory 5 for update registration. Even if a third party tries to unlock using the old key after the update registration, the updated identification code and the identification code of the old key do not match, so the unlocking is not performed. Next, some specific examples of the key 1 used in the above embodiment will be described. 4 and 5 show perspective views of different keys. In these keys 1D to 1G, the knobs 21 and 22 and the shafts 23 and 24 are both made of a non-magnetic material, and a plurality of rod-like magnets M20 as shown in FIG. Is.

The magnets M1 and M2 and the magnets M3 and M4 are arranged so that the north pole and the south pole are located in the same plane, and the north pole and the south pole are directed in opposite directions. The two planes related to the magnets M1 and M2 and the magnets M3 and M4 are orthogonal to each other. A key 1G in FIG. 5B has an annular knob 21 and four magnets M1 to M4 are arranged on a prismatic shaft 23 in the same manner as the key 1F.

  FIG. 6 shows a circuit board structure of a magnetic detection unit that detects the magnetism of the magnet of each key corresponding to each key shown in FIGS. 4 and 5. The magnetic detection unit 2A shown in FIG. 6 (a) with respect to the key 1D in FIG. 4 (b), and the magnetic detection unit in FIG. 6 (b) with respect to the key 1E in FIG. 4 (c). 2B is used in combination with the magnetic detection unit 2c of FIG. 6C for the keys 1F and 1G of FIGS. 5A and 5B.

  In the magnetic detection unit 2 </ b> A of FIG. 6A, four magnetic detection elements 30 (D <b> 1 to D <b> 4) are mounted on a printed board 31, and a lead frame 32 protrudes from the printed board 31. The magnetic detection elements D1 to D4 are arranged on a straight line corresponding to the four magnets M1 to M4 of the key 1D. In the magnetic detection unit 2B of FIG. 6B, five magnetic detection elements D1 to D5 are mounted on the printed circuit board 31 corresponding to the five magnets M1 to M5 of the key 1E. The magnetic detection elements D1 and D4 correspond to the magnetism M1 and M4 on a straight line. The magnetic detection elements D2 and D3 correspond to the magnets M2 and M3. The magnetic detection element D5 corresponds to the magnet M5. Furthermore, it is arrange | positioned on another straight line.

  6C includes printed circuit boards 31a and 31b that are attached orthogonal to each other. The printed circuit board 31a is provided with magnetic detection elements D1 and D2 corresponding to the magnets M1 and M2 of the keys 1F and 1G, and the magnetic detection element D3 corresponding to the magnets M3 and M4 of the keys 1F and 1G is provided on the printed circuit board 31b. D4 is provided. That is, the magnetic detection elements D1 and D2 and the magnetic detection elements D3 and D4 are arranged on planes orthogonal to each other.

  In FIG. 6, the printed circuit boards 31, 31a and 31b of the magnetic detection units 2A, 2B and 2C are shown with only the magnetic detection elements D1 to D5 mounted thereon. 31, 31 a, and 31 b are also mounted with a magnetic detection element D <b> 1 to D <b> 5 and a circuit that forms a magnetic detection circuit, but the illustration is omitted here. A magnetic detection circuit according to the magnetic detection element D1 is shown in FIG. The magnetic detection circuits according to the other magnetic detection elements D2 to D5 are the same as the circuit shown in FIG.

  In the magnetic detection circuit shown in FIG. 7, a Hall element is used as the magnetic detection element D1. The Hall element D1 generates a + IN signal when the applied magnetism is N polarity, and generates a -IN signal when the magnetism is S polarity. In the circuit shown in FIG. 7, the N pole, the non-magnetism, and the S pole are determined depending on whether the voltage generated in the Hall element D1 is + IN, 0, or −IN.

In the circuit of FIG. 7, the divided voltage V ₀ divided by the resistors R3 and R4 is
V ₀ = {R4 / (R3 + R4)} × V _cc
It becomes. If the N pole discrimination comparison voltage for detecting the N pole is V _n ,
V _n = {R6 / (R5 + R6)} × V _cc
It becomes. Further, when the S pole discrimination comparison voltage for detecting the S pole is V _s ,
V _s = {R8 / (R7 + R8)} × V _cc
It becomes. At this time, if V _n > V ₀ > V _s is set, the operations of the comparators C1 and C2 are as follows.

(B) the voltage of the output OUT2 of the magnetic detection element D1 when the magnetic is not, because there is no Hall voltage remains bias voltage V ₀ applied to OUT1. Therefore, since V _D = V ₀ and V _n > V _D , the output N1 of the comparator C1 is “L”, and since V _D > V _s , the output S1 of the comparator C2 is “L”. Since both N1 and S1 are “L”, the output M1 of the NOR circuit becomes “H” because the inputs are “L” and “L”, and generates a non-magnetic signal.

(B) When detecting the N pole When an N polarity magnetism is applied to the magnetic detection element D1, a positive Hall voltage is generated. If this voltage is + V _A ,
V _D = V ₀ + V _A
Thus, the voltage V _D increases.

When V _D > V _n , in the comparator C1, the positive input voltage exceeds the negative input voltage, the output N1 becomes “H”, and the comparator C1 generates an N pole detection signal. At this time, since V _D > V _s , the output of the comparator C2 remains “L” as it is. However, since the input of the NOR circuit becomes “L” and “H”, the output M1 becomes “L”, and the non-magnetic signal disappears.

(C) When detecting the S pole When S polarity magnetism is applied to the magnetic detection element D1, a negative Hall voltage is generated between OUT1 and OUT2. If this voltage is −V _B ,
V _D = V ₀ -V _B
Thus, the voltage V _D decreases.

When V _D > V _s , in the comparator C2, since the positive input voltage becomes larger than the negative input voltage, the output S1 of the comparator C2 becomes “H”, and the comparator C2 generates an S pole detection signal. At this time, since V _D <V _N , the output of the comparator C1 is “L”. Further, since the inputs of the NOR circuit are “L” and “H”, the output M1 thereof becomes “L”, and no magnetic signal is generated.

In a magnetic detection circuit composed of five circuits each including the magnetic detection elements D1 to D5, any one of the N pole, S pole, and no magnetism of each of the magnets M1 to M5 of the key 1E to be inserted is the magnetic detection element D1. D5 is input and detected. Since either N pole, S pole, or no magnetism is input for each magnet M1 to M5, the identification codes output from the magnetic detection circuit 3 and the discrimination circuit 4 are 3 ⁵ = 243 different codes. One code corresponding to the key 1E. If the number of magnets provided in the key 1 is eight and the number of magnetic detection elements of the magnetic detection circuit 3 is eight, one corresponding to the key 1 out of 3 ⁸ = 6561 different codes is output. That is, an identification code corresponding to key 1 which is one of 6561 is input to the apparatus.

With the keys 1E and 1 used here, a large number of combinations of codes can be obtained with a small number of magnets and magnetic detection elements. Incidentally, when using photoelectric elements and magnetic lead wire switches, in order to enable 6561 types of combinations, 2 ¹² = 4096 even if ¹² detection elements are used, which is very less than 6561. . Furthermore, if the same 8 pieces are used, only 256.

  FIG. 2 is a schematic perspective view of an electronic lock control device configured using the key 1E and the magnetic detection unit 2B. Here, the magnetic detection unit 2B is encapsulated with the determination circuit 4, the code setting memory 5,..., The AND gate 13 and the like of the control device main body 2 shown in FIG. It corresponds to the appearance of the device. In FIG. 2, a prismatic keyhole 51 into which the key 1E is inserted is formed in the case 50, and the magnetic detection unit 2B is disposed. If the key 1E is completely inserted into the key hole 51 of the case 50 in the correct orientation, the magnets M1 to M5 of the key 1E face the magnetic detection elements D1 to D5 of the magnetic detection unit 2B, and can be locked or unlocked. . In FIG. 2, a code update switch (key switch) 12 is provided on the upper surface of the case 50, and the switch 12 and the circuit unit are connected by lead wires so that an operation signal of the switch 12 is taken into the circuit unit of the magnetic detection unit 2B. Electrically connected.

  FIG. 3 shows a schematic perspective view of an electronic lock control device configured using the key 1H (modified example of the key 1F) and the magnetic detection unit 2A. Here, the electronic lock control shown in FIG. 1 is obtained by wrapping the magnetic detection unit 2A with circuit units such as the determination circuit 4, the code setting memory 5,... It corresponds to the appearance of the device. In FIG. 3, a cylindrical keyhole 52 into which the key 1H is inserted is formed in the case 50, and the magnetic detection unit 2A is disposed. The key 1H is arranged so that the magnetic pole of the magnet 20 is located in one plane, like the key 1D. If the key 1H is completely inserted into the key hole 52 of the case 50 and rotated, the magnets M1 to M4 of the key 1H face the magnetic detection elements D1 to D4 of the magnetic detection unit 2A and can be locked or unlocked. Become. Also in FIG. 3, the code update switch 12 is provided on the upper surface of the case 50, and the switch 12 and the circuit unit are electrically connected by a lead wire so that the operation signal of the switch 12 is taken into the circuit unit of the magnetic detection unit 2A. ing. By inserting the key 1H into the keyhole 52 and rotating it in the direction of the arrow by 90 ° from the state shown in the figure, the magnets M1 to M4 face the magnetic detection elements D1 to D4 and detect the magnetic signal from the magnet of the key 1H. .

  As the code update switch 12 operated to set the identification code registration update mode that is characteristically provided in the electronic lock control device of the above embodiment, a mechanical key switch is used as shown in FIGS. Although the case has been described, instead of this, an input operation means having the following mode may be adopted.

  As a first modification, for example, the key 1D shown in FIG. 4B is provided with a line 26 on the upper surface of the shaft 23, while the printed circuit board 31 shown in FIG. 2 is printed as shown in FIG. The electronic control device main body 2 is configured by incorporating the substrate 31. The printed circuit board 31 includes a circuit unit shown in FIG. The tip of the shaft 23 of the key 1D is inserted up to the line 26 in the key hole 51 of the electronic control device main body 2 and is held for a certain time T or longer in this state. By inserting the key 1D up to the line 26, the magnet M1 faces the magnetic detection element D4, and the magnets do not face the other magnetic detection elements D1 to D3. Accordingly, only the magnetic detection element D4 is logically “1”, the outputs of the other magnetic detection elements D1 to D3 are “0”, and the gate circuit 27 outputs the logical “1”. The output of the gate circuit 22 is input to the timer 28. The timer 28 outputs “1” when the time T elapses, and the gate circuit 29 outputs logic “1” at that time. When there is a logic “1” signal held for a certain period of time, when the key is placed in a predetermined position, the code of the inserted key is updated in the memory as a setting code by this logic signal.

  As a second modification, when the rotary key is rotated by a predetermined angle in the direction opposite to the direction of rotation for locking or unlocking, this reverse direction rotation detection is performed as a setting signal for the identification code registration update mode. To do. For example, as shown in FIG. 9, a small magnet 25 is provided at a right angle to the magnet 20 of the shaft 24 as viewed from the front end direction of the key 1 </ b> H shown in FIG. 3. The key 1H and the shaft 24 are completely inserted into the key hole 52, and then the key 1H is rotated by 90 ° in the direction opposite to the arrow direction in FIG. By this 90 ° rotation, the magnet 25 faces the magnetic detection element on the printed circuit board newly provided on the inner bottom surface of the case 50, and the magnetic detection element detects the magnetism of the magnet 25. When the magnetic detection signal of the magnetic detection element is held for a certain period of time and then the key is rotated to a predetermined angle and completely inserted, the code of the key is updated in the memory as a setting code.

  In the description of the above embodiment, the case where a key, particularly a key including a plurality of magnets, is used as the identification code input means for inputting the operator's identification code. However, the present invention is only a key using such a magnet. In addition, when inputting using a key having a plurality of light emitting elements, a plurality of magnetic reed switches, etc., the present invention can be widely applied to a case where a key button is operated to transmit and input an identification code wirelessly. .

  Furthermore, as another embodiment of the present invention, when a key is input for locking in the unlocked state without providing a code update switch, locking is performed with the key, and the key input for the locking is The identification code may be updated and registered. Specifically, in the circuit of FIG. 1, for example, when the code update switch 12 is omitted and the lock 1 is input in the unlocked state by the unlocking output signal of the flip-flop 7, the unlocked state and the locked state are input. The identification code of the key 1 newly input on condition that the key 1 is input is updated and registered in the code setting memory 5.

  As another example, a lock state / unlock state storage means for storing whether the lock is locked or unlocked is provided. When a key is inserted for unlocking in the locked state, the identification code registration unit The identification code is compared with the input key identification code, and if a match is obtained, the identification code registration unit is cleared and the unlocking signal is locked. If a key is inserted for locking in this unlocked state, a locking signal may be output without comparison, and the input identification code of the key may be updated and registered in the identification code registration unit.
