Detailed Embodiments
[0028] In order to better explain the present utility model for easy understanding, the present utility model will be described in detail below with reference to the drawings through specific embodiments.
[0029] See Figures 1-3 As shown, an interlocking control system for a magnetic lock proposed in an embodiment of the present utility model includes a door body 1A with a magnetic lock 1 and a door body 2A with a magnetic lock 2, and an activity space is formed between the door bodies 1A and 2A. It further includes an interlocking controller 3 disposed in the activity space between the door body 1A and the door body 2A, and a power supply 1 and a power supply 2 for respectively supplying power to the magnetic lock 1 of the door body 1A and the magnetic lock 2 of the door body 2A. First switch devices 4 are respectively disposed on both sides of the door body 1 and the door body 2, and second switch devices 5 are respectively disposed on both sides of the door body 1 and the door body 2. The first switch device 4 is electrically connected to the magnetic lock 1 of the door body 1A, the second switch device 5 is electrically connected to the magnetic lock 2 of the door body 2A, and the interlocking controller 3 is respectively electrically connected to the magnetic lock of the door body 1 and the magnetic lock of the door body 2. When the first switch device 4 / second switch device 5 is opened, the magnetic lock 1 of the door body 1A / the magnetic lock 2 of the door body 2A is opened, and the magnetic lock 1 of the door body 1A / the magnetic lock 2 of the door body 2A can send a first signal to the interlocking controller 3, and the interlocking controller 3 can receive the first signal and provide an additional power supply to the magnetic lock 2 of the door body 2A / the magnetic lock 1 of the door body 1A, so that the magnetic lock of the door body 2 / the magnetic lock of the door body 1 forms a two-way power-on state.
[0030] It should be noted that the magnetic lock 1 or the magnetic lock 2 can also be a combination of multiple magnetic locks.
[0031] An interlocking control system for a magnetic lock of the present utility model, without changing the wiring method of the two magnetic locks of the original two door bodies, separately electrically connects the interlocking controller 3 to the magnetic locks of the two door bodies. When the first switch device 4 / second switch device 5 is opened, when one of the magnetic locks corresponding to the door body is opened, the magnetic lock 1 of the door body 1A / the magnetic lock 2 of the door body 2A can send a first signal to the interlocking controller 3, and the interlocking controller 3 can receive the first signal and provide an additional power supply to the magnetic lock 2 of the door body 2A / the magnetic lock 1 of the door body 1A, so that the magnetic lock 2 of the door body 2A / the magnetic lock 1 of the door body 1A forms a two-way power-on state. In this way, even if the original power supply of the magnetic lock 2 / magnetic lock 1 is cut off, the magnetic lock 2 / magnetic lock 1 still remains in the locked state due to the additional power supply, realizing the interlocking requirement. And the interlocking controller has no independent control effect on the two magnetic locks, and the magnetic lock cannot be opened separately through the interlocking controller. It can meet the interlocking requirements of the two magnetic locks while having no actual control effect on the magnetic locks, without adding new risk points, and without changing the original wiring method and control logic of the magnetic locks, with small modification amount and low implementation difficulty.
[0032] Furthermore, the interlock controller 3 includes a power input module 31 and two control modules 32. The power input module 31 is connected to the two control modules 32 respectively, and is used to provide power for the control modules 32 respectively. The two control modules 32 are electrically connected to the magnetic lock 1 of the first door body 1A and the magnetic lock 2 of the second door body 2A respectively. The control module 32 is used to receive the switch lock feedback signals of the magnetic lock 1 of the first door body 1A and the magnetic lock 2 of the second door body 2A. Among them, the unlocking feedback signal is used as the first signal, and the locking feedback signal is used as the second signal. The control module 32 can also judge whether to supply additional power to the magnetic lock 1 of the first door body 1A / the magnetic lock 2 of the second door body 2A according to the first signal or the second signal received by it. Here, it should be emphasized that the purpose of adding power is to ensure that when the magnetic lock 1 of the first door body 1A is opened, the unlocking feedback signal, that is, the first signal, is fed back to the control module 32 of the interlock controller at this time. When the control module 32 receives the first signal, it supplies additional power to the magnetic lock 2 of the second door body 2A. In this way, even when the magnetic lock 2 of the second door body 2A is opened through the second switch device 5 and its original power supply 2 is cut off, there is still the power input module 31 of the interlock controller 3 to supply additional power to the magnetic lock 2 of the second door body 2A through the wire, so that the magnetic lock 2 of the second door body 2A cannot be opened, thus effectively ensuring the interlock function that the second door body 2A cannot be opened when the first door body 1A is opened. The principle is the same when the second door body 2A is opened and the first door body 1A cannot be opened, and no more details will be elaborated here.
[0033] Further, the control module 32 includes a relay 321, a signal feedback module 322, and a power output terminal 323. The input end of the relay 321 is connected to the power input module 31, the output end of the relay 321 is connected to the power output terminal 323 of another control module 32, and the relay 321 is also connected to the signal feedback module 322. The signal feedback module 322 is connected to the magnetic lock of its corresponding door body and is used to receive the switch lock signal of its corresponding magnetic lock and feedback the switch lock signal to the relay 321. After receiving the first signal or the second signal, the relay 321 supplies power to the power output terminal 323 of another control module 32. Specifically, without changing the original wiring method of the two magnetic locks of the first door body 1A or the second door body 2A, a set of signal feedback lines of the magnetic lock 1 and the magnetic lock 2 are re-connected to the signal feedback module 32 on the control module 32 and a set of power lines are connected to the power output terminal 323 on the control module 32. In addition, a relay 321 is configured in the control module 32 of the interlock controller 3. When the magnetic lock 1 is opened, the first signal is sent to the relay 321 through the signal feedback line of the signal feedback module 32. After receiving the first signal, the relay 321 can add a power output to the power output terminal 323 of the magnetic lock 2, so that the magnetic lock 2 forms a dual-path power-on state. In this way, even if the unlocking verification of the switching device of the magnetic lock 2 passes and the original power supply of the magnetic lock 2 is cut off, the magnetic lock 2 still remains in the locked state due to the additional power supply, realizing interlock.
[0034] Further, the control module 32 further includes a magnetic lock status dry signal feedback output terminal 324. The magnetic lock status dry signal feedback output terminal 324 is used to output the magnetic lock switch lock dry signal to the outside. When the outside needs to know the status of the magnetic lock of the door body, the magnetic lock status dry signal feedback output terminal 324 can also be connected to a specified position to feedback the lock status dry signal, which can be timely feedback to the outside world.
[0035] Here, after the wiring of the magnetic lock 1 of the door body 1A and the magnetic lock 2 of the door body 2A of the interlock controller 3 is completed, the interlock controller 3 can realize the control system in which only one of the magnetic lock 1 of the door body 1A and the corresponding magnetic lock 2 of the door body 2A can be opened at the same time. For the convenience of description, the magnetic lock corresponding to the door body 1A is hereinafter referred to as the magnetic lock 1; the magnetic lock corresponding to the door body 2A is hereinafter referred to as the magnetic lock 2. The initial state is set to that both locks are in the locked state. When the magnetic lock 1 is opened, the magnetic lock 1 feeds back the on-off signal of the lock opening to the interlock controller 3 as the first signal. After the relay 321 on the control module 32 corresponding to the magnetic lock 1 receives the first signal, it provides an additional power supply for the power output terminal 323 of the magnetic lock 2. In this way, even if the verification through the second switch device 5 is passed and the original power supply 2 is cut off, the magnetic lock 2 cannot be opened because of the additional power supply. When the magnetic lock 1 is locked, the magnetic lock 1 feeds back the on-off signal of the lock opening to the interlock controller 3 as the second signal. The interlock controller 3 stops the additional power supply for the magnetic lock 2 through the relay 321. At this time, the relay 321 does not output power to the output terminal 323 of the magnetic lock 2. At this time, the magnetic lock 2 is still in the locked state and can be unlocked through the original verification method of the second switch device 5. Similarly, when the magnetic lock 2 is opened, the magnetic lock 1 cannot be unlocked through the original verification method either, so as to realize the control system in which only one of the two magnetic locks can be opened at the same time.
[0036] Further, the power input module 31 includes a power input terminal 311, an output voltage adjustment module 312, and a voltage stabilization module 313. The power input terminal 311 is connected to the input terminal of the output voltage adjustment module 312. The power input terminal 311 is used to provide power for the relay 321, and further provide power for the magnetic locks of the door body 1 / door body 2. The output terminal of the output voltage adjustment module 312 is connected to the input terminal of the voltage stabilization module 313, and is used to adjust the voltage of the power output to the magnetic lock, so that the voltage of the additional power supply of the control module 32 is less than the voltage of the original power supply in the unlocked state of the magnetic lock. The output terminal of the voltage stabilization module 313 is respectively connected to the relay 321 input terminals of the two control modules 32. The voltage stabilization module 313 can process the voltage difference when both the original power supply 1 / power supply 2 in the unlocked state of the magnetic lock and the additional power supply of the control module 32 supply power to the magnetic lock 1 of the door body 1A / magnetic lock 2 of the door body 2A and there is a voltage difference between the two.
[0037] It should be noted that when the magnetic lock 1 is turned on and the interlock control board supplies power to the magnetic lock 2, there will be a situation where two power supplies are connected in parallel to supply power to the magnetic lock 2 simultaneously. In this case, since it is impossible to ensure that the voltages of the two power supplies are exactly equal, to prevent the power backflow caused by the voltage difference from affecting the service life of the power supply, during the implementation process, the output voltage adjustment module 312 is required to adjust the output voltage of the additional power output terminal 323 of the magnetic lock to be slightly lower than the original power supply voltage of the magnetic lock, and then the voltage difference flowing back to the interlock control board is processed by the voltage stabilization module 313.
[0038] Furthermore, the output voltage adjustment module 312 includes two fixed resistors, a variable resistor, and a potentiometer. The potentiometer has three pins, with the two pins at both ends respectively connected to the two fixed resistors, and the middle pin connected to the variable resistor, which is used to adjust the output power supply voltage. The wiring is simple and the operability is strong.
[0039] Furthermore, both the first switch device 4 and the second switch device 5 include two verification and identification devices provided on both sides of the door 1 / door 2. It can be identified from the inside and outside of the door 1 or the door 2 respectively. The first switch device 4 can verify the identity of the personnel entering the door 1A, and the second switch device 5 can verify the identity of the personnel entering the door 2A.
[0040] Furthermore, the verification and identification device is fingerprint biometric authentication. It can accurately identify the identity information of those entering the door 1 or the door 2.
[0041] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model should also include these modifications and variations.
