In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0056] Refer to Figure 1 , Figure 1 which is a schematic diagram of the modules of the first embodiment of the access control device proposed by the present utility model. Based on Figure 1 the first embodiment of the access control device of the present utility model is proposed.

[0057] In this embodiment, the access control device includes: a central processing unit 10, a 4G network module 20, and an electromagnetic access control switch 30 that are integrally arranged; the central processing unit 10 is respectively connected to a power supply 40, a 4G network module 20, and the control end of an electromagnetic switch module through cables; the input end of the electromagnetic access control switch 30 is connected to the power supply 40 through a cable, the 4G network module 20 is connected to the power supply 40 through a cable, and the output end of the electromagnetic access control switch 30 is connected to a door lock 50 through a cable.

[0058] It should be noted that the 4G network module 20 can be a communication device capable of interacting with the cloud. It can receive the electromagnetic waves sent by the cloud, convert the electromagnetic waves into electrical signals and send them to the central processor 10, or receive the electrical signals sent by the central processor 10 and convert the electrical signals into electromagnetic waves and send them to the cloud. Therefore, through the mutual conversion of electromagnetic waves and electrical signals by the 4G network module 20, the central processor 10 can execute the instructions sent by the cloud and can also send device information to the cloud. In this embodiment, the 4G network module 20 can receive the first control instruction sent by the cloud, convert the first control instruction into a first control signal, and send it to the central processor 10. The first control instruction is an instruction sent by the cloud to the 4G network module 20 after the customer pays the fee through a mobile terminal or other means and sends an opening request to the cloud. After receiving the first control instruction, the 4G network module 20 converts the instruction into an electrical signal to obtain a first control signal, and sends the first control signal to the central processor 10 so that the central processor 10 can execute the customer's opening request.

[0059] It should be noted that the central processor 10 can be, for example, a single-chip microcomputer or a microcontroller unit (MCU), which can execute corresponding operations and output corresponding voltage signals when receiving a certain signal through a pre-set program. The central processor 10 can receive the signal sent by the 4G network module 20 and execute the operation corresponding to the signal. In this embodiment, when the central processor 10 receives the first control signal sent by the 4G network module 20, it will send a first drive signal to the electromagnetic door lock switch 30. After receiving the first drive signal, the electromagnetic door lock switch 30 will close, conducting the connection between the power supply 40 and the door lock 50. The power supply 40 is an external 220V alternating current, which converts the alternating current into various DC control voltages required inside the device, including 12V, 5V, 3.3V, etc. The door lock 50 can be a normally closed electromagnetic door lock 50. In the absence of power supply, the door lock 50 will remain in the locked state. When the door lock 50 receives the power supply 40, the electromagnet generates a magnetic force to attract the armature and unlock the door.

[0060] It should be noted that when the central processing unit 10 receives the first control signal, it can continuously send a first driving signal to the electromagnetic door lock switch 30 for a preset duration, so that the electromagnetic door lock switch 30 remains open for the preset duration, thereby ensuring that the user has sufficient time to open the door. After the preset duration is reached, the central processing unit 10 stops sending the first driving signal to the electromagnetic door lock switch 30, and the electromagnetic door lock switch 30 disconnects, and the door lock 50 will be locked when powered off. The preset duration can be adjusted by setting the program of the central processing unit 10, and there is no rigid requirement. At the same time, the user can also choose to close the door in advance on the mobile terminal. The cloud will send a door closing instruction to the 4G network module 20. The 4G network module 20 receives the door closing instruction and converts it into a door closing signal and sends it to the central processing unit 10. The central processing unit 10 immediately stops sending the first driving signal to the electromagnetic door lock switch 30 to close the door lock 50.

[0061] In this embodiment, by using a cable to transmit signals, the problem of unstable signal transmission caused by factors such as occlusion is avoided, so as to realize stable control of the opening of the door lock and improve the user experience.

[0062] Refer to Figure 2 , Figure 2 It is a schematic diagram of the modules of the second embodiment of the access control device proposed by the present invention. The second embodiment of the access control device of the present invention is proposed based on the first embodiment of the above access control device.

[0063] In this embodiment, the access control device further includes: a manual door lock switch 31; the manual door lock switch 31 is respectively connected to the power supply 40 and the door lock 50 through a cable;

[0064] It should be noted that the manual door lock switch 31 can be a single-control single-pole switch. The manual door lock switch 31 is inside the room. When the manual door lock switch 31 is triggered, the connection between the power supply 40 and the door lock 50 will be conducted, so that the door lock 50 is opened.

[0065] In this embodiment, the access control device further includes: a first high-voltage switch 61 and a first high-voltage power supply circuit 71; the control end of the first high-voltage switch 61 is connected to the central processing unit 10 through a cable, the input end of the first high-voltage switch 61 is connected to the power supply 40 through a cable, the output end of the first high-voltage switch 61 is connected to the first high-voltage power supply circuit 71 through a cable, and the first high-voltage power supply circuit 71 is connected to a device that matches the output current of the first high-voltage circuit;

[0066] It should be noted that the first high - voltage power supply circuit 71 is used to supply power to low - power devices 81 such as mahjong machines, lamps and other small - power electrical appliances, and the maximum current of its circuit can be 10A; in this embodiment, the first high - voltage circuit can use an electromagnetic switch. When the user sends a power - supply request for a small - power electrical appliance to the cloud through the mobile terminal, the cloud sends a second control instruction to the 4G network module 20. The 4G network module 20 receives the second control instruction and converts it into a second control signal, and then sends the second control signal to the central processor 10. The central processor 10 sends a second drive signal to the first high - voltage switch 61. When the first high - voltage switch 61 receives the second drive signal, it conducts the connection between the first high - voltage circuit and the power supply 40. At this time, the power supply 40 is connected to the electromagnetic switch in the first high - voltage circuit. The coil of the electromagnetic switch is energized, generating electromagnetic attraction, causing the movable iron core to move, driving the contacts of the switch to close, so that the first high - voltage circuit is connected, and thus the small - power electrical appliance is powered on.

[0067] It should be noted that the second control instruction here is an electromagnetic wave signal. The 4G network module 20 receives the electromagnetic wave signal and converts it into an electrical signal, that is, the second control signal corresponding to the second control instruction.

[0068] It can be understood that after receiving the second control instruction, the central processor 10 sends a second drive signal with a preset duration to the first high - voltage switch 61. The preset duration corresponds to the customer's payment amount, and a corresponding second control instruction is sent according to the customer's payment amount. The central processor 10 determines the preset duration for sending the second drive signal to the first high - voltage switch 61 by receiving the second control signal corresponding to the second control instruction.

[0069] In this embodiment, the access control device further includes: a second high - voltage switch 62 and a second high - voltage power supply circuit 72; the control end of the second high - voltage switch 62 is connected to the central processor 10 through a cable, the input end of the second high - voltage switch 62 is connected to the power supply 40 through a cable, the output end of the second high - voltage switch 62 is connected to the second high - voltage power supply circuit 72 through a cable, and the second high - voltage power supply circuit 72 is connected to a device that matches the output current of the second high - voltage power supply circuit 72.

[0070] It should be noted that the second high-voltage power supply circuit 72 is used to supply power to high-power devices 82 such as central air conditioners and other high-power electrical appliances, and its maximum current can be 50A. In this embodiment, when the user sends a power supply request for a high-power electrical appliance to the cloud through the mobile terminal, the cloud sends a third control instruction to the 4G network module 20. The 4G network module 20 receives the third control instruction and converts it into a third control signal, and then sends the third control signal to the central processor 10. The central processor 10 sends a third drive signal to the second high-voltage switch 62. When the second high-voltage switch 62 receives the third drive signal, it conducts the connection between the second high-voltage circuit and the power supply 40. At this time, the power supply 40 is connected to the electromagnetic switch in the second high-voltage circuit. The coil of the electromagnetic switch is energized to generate electromagnetic attraction, which moves the movable iron core and drives the contacts of the switch to close, so that the second high-voltage circuit is connected, and the high-power electrical appliance is energized.

[0071] It should be noted that the third control instruction here is an electromagnetic wave signal. The 4G network module 20 receives the electromagnetic wave signal and converts it into an electrical signal, that is, the third control signal corresponding to the third control instruction.

[0072] It can be understood that after receiving the third control instruction, the central processor 10 sends a third drive signal with a preset duration to the second high-voltage switch 62. The preset duration corresponds to the customer's payment amount, and a corresponding third control instruction is sent according to the customer's payment amount. The central processor 10 determines the preset duration for sending the third drive signal to the second high-voltage switch 62 by receiving the third control signal corresponding to the third control instruction.

[0073] In this embodiment, the power supply circuit of the electrical appliances in the room is connected to the processor through a cable, which avoids the problem of unstable signal transmission caused by factors such as occlusion in wireless transmission, and can realize more stable control of high-power electrical appliances and small-power electrical appliances in the room, improving the user experience.

[0074] Refer to Figure 3 , Figure 3 is a schematic diagram of the modules of the third embodiment of the access control device proposed by the present invention. Based on the first embodiment of the above access control device, the third embodiment of the access control device of the present invention is proposed.

[0075] In this embodiment, the access control device further includes: a human body detection module 90; the human body detection module 90 is respectively connected to the power supply 40 and the central processor 10 through cables;

[0076] It should be noted that the human body detection module 90 can be, for example, an infrared detector, which detects the presence of a human body by utilizing the difference between the infrared radiation emitted by the human body and the background environment. In this embodiment, when the human body detection module 90 detects that there is someone in the room, it sends a first detection signal to the central processor 10. After receiving the first detection signal, the central processor 10 will judge the on-off states of the electromagnetic access control switch 30, the first main power switch 61, and the second main power switch 62, that is, whether the central processor 10 itself is also sending a first drive signal, a second drive signal, and a third drive signal at the same time. If the central processor 10 detects that none of the first drive signal, the second drive signal, and the third drive signal are being sent, it means that the electromagnetic access control switch 30, the first main power switch 61, and the second main power switch 62 are all in the off state, then it is judged as an abnormal situation, indicating that someone has entered the room without paying. At this time, the central processor 10 will send an alarm signal to the 4G network module 20. After receiving the alarm signal, the 4G network module 20 will convert the electrical signal into an electromagnetic wave and send the alarm instruction to the cloud to remind that it is an abnormal state at this time; and when the central processor 10 receives the first detection signal and judges that there is a closed one among the electromagnetic access control switch 30, the first main power switch 61, and the second main power switch 62, that is, the central processor 10 itself is also sending at least one of the first drive signal, the second drive signal, and the third drive signal at the same time, it means that the room is in a normal use state at this time, then the current states of the electromagnetic access control switch 30, the first main power switch 61, and the second main power switch 62 are maintained. When the human body detection module 90 detects that there is no one in the room, it sends a second detection signal to the central processor 10. After receiving the second detection signal, the central processor 10 will judge the on-off states of the electromagnetic access control switch 30, the first main power switch 61, and the second main power switch 62, that is, whether the central processor 10 itself is also sending the first drive signal, the second drive signal, and the third drive signal at the same time. If it is detected that the central processor 10 itself is also sending at least one of the first drive signal, the second drive signal, and the third drive signal at the same time, then after a preset time period, the closed switch among the electromagnetic access control switch 30, the first main power switch 61, and the second main power switch 62 will be turned off, that is, the central processor 10 will stop sending the first drive signal, the second drive signal, and the third drive signal after the preset time period. The preset time period can be adjusted by setting the program of the central processor 10, and this solution does not limit it. In this solution, when the human body detection module 90 detects that there is no one in the room and at the same time the central processor 10 detects that there is a closed one among the electromagnetic access control switch 30, the first main power switch 61, and the second main power switch 62 in the room, after the preset time period, it means that the customer has left, and the power supply of the room will be cut off to play an energy-saving role.When the human body detection module 90 detects that there is no one in the room, it sends a second detection signal to the central processor 10. After receiving the second detection signal, the central processor 10 will judge the on / off states of the electromagnetic access control switch 30, the first main power switch 61, and the second main power switch 62, that is, whether the central processor 10 itself is also sending the first driving signal, the second driving signal, and the third driving signal at the same time. If it is detected that the central processor 10 itself does not send the first driving signal, the second driving signal, and the third driving signal, it means that the electromagnetic access control switch 30, the first main power switch 61, and the second main power switch 62 are all in the off state. At this time, the room is in a normal closed state, and the off states of the electromagnetic access control switch 30, the first main power switch 61, and the second main power switch 62 in the room are maintained.

[0077] In this embodiment, the access control device further includes: a high-quality voice player 100 and a built-in voice library 101; the high-quality voice player 100 is respectively connected to the central processor 10 and the power supply 40 through cables; the built-in voice library 101 is connected to the high-quality voice player 100 through a cable.

[0078] It should be noted that the built-in voice library 101 can be voice data stored on, for example, an SD card. The high-quality voice player 100 can extract the corresponding voice data in the SD card according to the signal sent by the processor. The high-quality voice player 100 can be various audio devices for playing the corresponding voice in various situations. For example, when the central processing unit 10 sends a first driving signal, it will also send a first voice control signal to the high-quality voice player 100. When the central processing unit 10 sends the first driving signal to the electromagnetic door lock switch 30, it indicates that the door lock 50 is about to open and the customer is about to enter the room. At this time, the first voice control signal sent by the central processing unit 10 to the high-quality voice player 100 controls the high-quality voice player 100 to play voices such as "Welcome" and "Have a nice play". The specific voice can be set through the built-in voice library 101, and this solution does not make any limitations. When the central processing unit 10 sends a second driving signal, it will also send a second voice control signal to the high-quality voice player 100. When the central processing unit 10 sends the second driving signal to the first high-power switch 61, it indicates that the customer wants to turn on the low-power electrical appliances in the room. At this time, the second voice control signal sent by the central processing unit 10 to the high-quality voice player 100 controls the high-quality voice player 100 to play prompts such as "The mahjong machine has been turned on" and "The lights have been turned on" to inform the customer that these electrical appliances have been powered on and can be used normally. When the central processing unit 10 sends a third driving signal, it will also send a third voice control signal to the high-quality voice player 100. When the central processing unit 10 sends the third driving signal to the second high-power switch 62, it indicates that the customer wants to turn on high-power electrical appliances such as the central air conditioner. At this time, the third voice control signal sent by the central processing unit 10 to the high-quality voice player 100 controls the high-quality voice player 100 to play voices such as "The air conditioner has been turned on" to inform the customer that these electrical appliances have been powered on and can be used normally.
