Description

Technical Field

[0001] The utility model relates to the technical field of security equipment, in particular to a novel security equipment. Background Art

[0002] With the development of industrial technology, the functions of door locks are becoming more and more perfect. In addition to opening the door by key, some existing door locks can also open the door by password, which brings great convenience to people.

[0003] The authorized patent of my country with patent number "202223371610.9" and patent name "A side button password door lock" records that "the utility model has a novel structure. By pressing one side of the movable plate, the movable plate rotates inside the slot through the connecting seat. After rotation, the movable plate tilts open. When tilted open, it provides a shield for the password to avoid the password input being visible from the front." As can be seen from the above, although the comparative patent has achieved the technical effect of the utility model described in it, it is limited by the structure. Like other existing password door locks, there are still the following technical problems that need to be solved. First, it cannot provide lighting function for users when the light is not good at night, so it is not convenient for users to enter the password to open the door lock when the light is not good. Second, it does not have a security function and cannot monitor the password buttons pressed by illegal personnel. In other words, it provides sufficient time for illegal personnel to try and input the password sequence of pressing different buttons. In this way, there is a chance that illegal personnel will open the door. In summary, it is particularly necessary to provide a security device based on an electromagnetic door lock body that can provide lighting when the light is poor and can alarm as soon as an illegal person presses the wrong password button.

The trigger circuit includes a pyroelectric detection module T4 and a time relay module T5 connected via circuit board wiring. The positive power output terminal 3 of the pyroelectric detection module T4 is connected to the positive power input terminal 1 of the time relay module T5 and the positive trigger signal input terminal 3. The negative power input terminal 2 and the negative trigger signal input terminal 4 of the time relay module T5 are connected to the negative power input terminal 2 of the pyroelectric detection module T4 (the detection surface of the pyroelectric detection module T4 is located outside another opening at the front end of the shell). The power module can also use a battery, which is located in the shell on one side of the anti-theft door. The battery power output terminal is electrically connected to the power input terminal of the detection circuit and the trigger circuit, and the battery is charged after it runs out of power.

[0019] Figure 1 , 2As shown, the power input terminals 1 and 2 of the power module T1 are connected to the two poles of the AC 220V power supply through wires, respectively, and the power output terminals 3 and 4 of the power module T1 are connected to the positive power input terminal 1 and negative power input terminal 2 of the time relay module T2 of the detection circuit, and the power input terminals 1 and 2 of the pyroelectric detection module T4 of the trigger circuit are connected through wires. The normally open contact terminal of the relay J1 of the detection circuit is connected to the positive power input terminal of the SMS module T3 through wires, the normally closed contact terminal of the relay J1 is connected to the control power input terminal of the relay J2 through wires, and the negative power input terminal of the buzzer B is connected to the 4th pin of the power module T1 through wires. The 5th and 2nd pins of the time relay module T5 of the trigger circuit signal output terminal and the 1st and 2nd pins of the SMS module T3 of the alarm circuit signal input terminal are connected through wires. The 3rd and 2nd pins of the pyroelectric detection module T4 of the trigger circuit control output terminal and the 1st and 2nd pins of the light-controlled switch T6 of the lighting circuit power input terminal are connected through wires. The normally open contact end and the negative power input end of the control signal end relay J2 of the alarm circuit are connected to the two ends of the DC power input of the electromagnetic lock core of the electromagnetic door lock through wires. The key switches are divided into two groups, each group has multiple keys, and the power input end and the power output end of one group of 16 key switches S1N are connected together through wires, and the power input end and the power output end of one group of 16 key switches are connected to the positive power output end 3 pin of the power module T1 and the positive trigger signal input end 3 pin of the time relay module T2 of the detection circuit through wires. Between the other group of 4 key switches S2N, the power output end and the power input end of each adjacent two power switches S2N are connected through wires, and the power input end of the first end key switch S2N and the power output end of the last key switch S2N of the other group of 4 key switches S2N are connected in series between the two trigger end relay J2 control power input end and the positive power input end of the alarm circuit through wires.

[0020] Figure 1 , 2As shown, after the power input end of the power module T1 is input with an AC 220V power supply, the 3rd and 4th pins of the power module T1 output a stable DC 12V power supply which enters the power input end of the detection circuit and the trigger circuit. In the present invention, when the user knows the password number composed of the four push switches S2N, he presses the buttons of the corresponding four push switches S2N with his fingers, and the internal contacts of the corresponding four push switches S2N are closed (the power input end and the power output end of the four push switches S2N are connected in series). In this way, the 12V power supply enters the positive power input end of the relay J2 through the control power input end and the normally closed contact end of the relay J1, and the four power input ends and the power output ends of the push switches S2N connected in series enter the positive power input end of the relay J2. The relay J2 is energized to attract and control the power input end and the normally open contact end to close. Then, the power input end of the electromagnetic valve core DC is energized, and the electromagnetic lock core DC of the electromagnetic door lock drives the lock tongue to move to the right inner side after being energized. The lock tongue and the lock box installed on the door frame are separated, and the user can open the door. In actual situations, when other illegal personnel do not know the door opening password composed of the four push switches S2N, as long as any one of the four push switches S2N is not turned on, since the power input and power output ends of the four push switches S2N cannot be connected in series, the electromagnetic lock core DC will not be powered and the door will not be opened. In actual application, after the door is opened, the user presses and closes the four pushbutton switches S2N (internal contacts are open), so that the electromagnetic lock core DC loses power, and the electromagnetic lock tongue of the electromagnetic door lock moves to the left after the electromagnetic lock core loses power. After entering the room, the user turns on the toggle power switch S3, and the power switch S3 shorts the normally closed contact end of the relay J1 and the positive power input end of the relay J2. In this way, the relay J2 is energized to attract the control power input end and the normally open contact end to close, and then, the electromagnetic lock tongue of the electromagnetic door lock moves to the right inside after the electromagnetic lock core DC is energized; after the door is closed, the user turns off the power switch S3, and the power switch S3 no longer shorts the normally closed contact end of the relay J1 and the positive power input end of the relay J2, and the electromagnetic lock core DC loses power. After the electromagnetic lock core of the electromagnetic door lock loses power, the electromagnetic lock tongue moves to the left, and the lock tongue can enter the lock box of the door frame to achieve the purpose of closing the door indoors. Before going out, turn on the power switch S3, and the electromagnetic lock cylinder DC is energized, and the electromagnetic lock tongue moves to the right inner side, so that the door can be opened. After going out, the user turns off the power switch S3, the electromagnetic lock cylinder DC loses power, and then turns on the four push switches S2N. After the electromagnetic lock cylinder DC is energized, the electromagnetic lock tongue moves to the right inner side. After closing the door, turn off the four push switches S2N again to enter the state of preventing illegal persons from opening the door after closing (the electromagnetic lock cylinder of the electromagnetic door lock loses power and the electromagnetic lock tongue moves to the left, and the lock tongue can enter the lock box of the door frame).

[0021] Figure 1 , 2As shown, in actual application, when an illegal person does not know the password composed of the four push switches S2N and presses to open any one of the 16 push switches S1N, the 12V power supply will enter the 3rd pin of the time relay module T2, so the 5th pin of the time relay module T2 outputs a 2-minute power supply (time is adjustable) to the positive power input terminal of the relay J1, and the relay J1 is energized to close the control power input terminal and the normally open contact terminal, and the control power input terminal and the normally closed contact terminal are open; after the relay J1 is energized to close the control power input terminal and the normally closed contact terminal, the first power switch at the head end of the four push switches S2N will lose power. In this way, even if the illegal person correctly opens the four push switches S2N later, the relay J2 will not be energized, and the solenoid valve core DC will not be energized to open, which plays a role in preventing illegal door opening. After relay J1 is energized to attract the control power input terminal and the normally open contact terminal to close, the SMS module T3 and the positive power input terminal of the buzzer B are energized, and the buzzer B is energized to sound to warn illegal personnel. The SMS module T3 is energized to send out SMS messages. After the security guard's mobile phone receives the SMS, he can immediately know which specific resident has illegally opened the door and deal with it on the spot in time (the SMS content of each resident's SMS module is different, and the SMS content sent by all residents is uniformly received by the security guard's mobile phone). After 2 minutes, the 5th pin of the time relay module T2 stops outputting power, and the relay J1 loses power again to open the control power input terminal and the normally open contact terminal, and close the control power input terminal and the normally closed contact terminal. The SMS module and the buzzer are both de-energized and no longer work, laying the foundation for the user to open the door normally. The subsequent circuit of this application is powered on for 2 minutes, which correspondingly increases the interval trial and error time of illegal personnel, and can play a good anti-theft effect.

[0022] Figure 1 , 2As shown, when no one is standing in front of the door, the 3rd pin of the pyroelectric detection module T4 does not output power. When someone is standing about 1 meter in front of the door, the 3rd pin of the pyroelectric detection module T4 outputs a high level and enters the 1st and 3rd pins of the time relay module T5 and the power input terminal of the light control switch T6. When it is daytime and the light is strong, the 3rd pin of the light control switch T6 does not output a high level, and the lighting lamp H will not be powered by electricity and emit light; when the surrounding light is weak, the 3rd pin of the light control switch T6 outputs a high level and enters the positive power input terminal of the lighting lamp H, and the lighting lamp H will be powered by electricity and emit light, which provides convenience for users to open the door. After the time relay module T5 is powered on, it will delay for about 15 seconds (the time is adjustable), and its 6th foot will output a high level for 10 seconds to enter the SMS module T3 and the positive power input terminal of the buzzer B to be powered, and the buzzer B will be powered to sound to warn illegal personnel, and the SMS module T3 will be powered to send out SMS. After the security guard's mobile phone receives the SMS, he can immediately know which specific household has the probability of illegal door opening, and deal with it on the spot in time. After the 15-second delay of this application, the 5th foot of the time relay module T5 will output power. Under normal circumstances, illegal personnel cannot open the door within 15 seconds (the user will not open the door normally for more than 15 seconds), thus preventing unnecessary alarms of the SMS module and buzzer during the normal door opening time of the user.

[0023] Figure 2In the figure, the power module T1 is a finished product of an AC 220V to DC 12V switching power module (brand Meanwell). The time relay modules T2 and T5 are finished products of a delay time relay module of model K1305-V2.1, which have two power input terminals, two trigger signal input terminals, four setting buttons, and one power output terminal. By operating the four setting buttons, the time interval and duration of the power output terminal outputting power after the trigger signal input terminal inputs the trigger signal can be set. The SMS module T3 is a finished product of a wireless remote mobile phone SMS alarm of brand Biyin Technology and model 834 (with two power input terminals and six signal input terminals. After each signal input terminal inputs a low level, it can send a text message respectively. The mobile phone connected to the SMS module can receive text messages. In this embodiment, the content of the SMS module of each household is inconsistent. For example, the SMS content 01025 represents Building 1, Unit 2, and Floor 5. In this way, the guard can get the exact location and go to the scene as soon as possible after receiving the SMS). The buzzer B is a finished product of a high-decibel active continuous sound buzzer of model SFM-27; relays J1 and J2 are DC 12V relays; and the lighting lamp H is a 5W, 12V incandescent lamp. The pyroelectric detection module T4 is a finished product of the HC-SR312 micro-human infrared sensor module, which has two power input terminals and one signal output terminal. When there is a person at the front end of the detection head, the signal output terminal outputs power, otherwise it does not output power (the pyroelectric detection module has a distance adjustment knob. When the technician adjusts the adjustment handle to the left, the detection distance becomes closer, otherwise it becomes farther. This new model is adjusted to about 1 meter); the light-controlled switch T6 is a finished product of the light-controlled switch of model AS-20, with a working voltage of DC 12V. It has two power input terminals and one power board output terminal. When the light at the outer end is strong, the power output terminal does not output power, otherwise it outputs power.
