Description

Technical Field

[0001] This utility model relates to the field of field guidance cabin technology, and in particular to an ellipsoidal field guidance cabin with a sliding door. Background Technology

[0002] A field-guided chamber is a specialized device utilizing biofield guiding technology, primarily composed of a support frame and a spherical chamber. It transmits plant vital signs through non-magnetic metallic materials within the chamber to achieve a biofield guiding effect on the human body. The chamber contains a receiving chamber and a processing chamber. The receiving chamber acquires biomicrowaves from plant seedlings and transmits them via waveguides to a resonant chamber for tuning and amplification. Finally, it is transmitted via a transmitting antenna to the processing chamber for reception by the human body. Currently, field-guided chambers are typically opened and closed via a door, which is mostly either entirely manual or entirely electrically controlled. There is currently no type that is compatible with both manual and electrically controlled methods.

A handle 7 is fixedly connected to the door 6. The cabin includes a base 1, an octagonal support plate 2 fixedly connected to the base 1, several main keels 8 fixedly connected to the octagonal support plate 2, and an upper keel 9 fixedly connected to the upper end of the several main keels 8.

Figure 4 As shown, the card reader module 12 includes an MFRC522 contactless card reader / writer chip, and the stepper motor 13 includes a ULN2003 driver board and a 28BYJ4 stepper motor coupled to it. The 28BYJ4 stepper motor is coupled to the STM32 microcontroller through the ULN2003 driver board. Figure 5 As shown, the delay circuit 14 includes an RC delay circuit, and the drive switch circuit 15 includes a first transistor switch and a relay. The output terminal of the RC delay circuit is coupled to the base of the first transistor switch. The collector of the first transistor switch is energized, and the emitter of the first transistor switch is connected to the relay and then grounded. Figure 5 As shown, the controlled switch circuit 16 includes a normally open relay switch controlled by a relay. The normally open relay switch is connected in series between the control module 11 and the motor drive circuit 17. The motor drive circuit 17 includes a TB67S109AFTG motor drive chip.

[0041] The output shaft of the servo motor 18 is coaxially fixedly connected to a take-up roller. The outer ring of the take-up roller is wound with a pull rope fixedly connected to the hatch 6. After the smart card door lock is unlocked, the servo motor 18 works with a delay. It also includes a door position detection circuit, which is coupled to the servo motor 18. The door position detection circuit detects the distance of the hatch 6 relative to the opening side and controls the servo motor 18 to turn on and off.

[0042] like Figure 2 and Figure 6As shown, the gate position detection circuit includes a distance sensor 19, a signal amplification circuit 20, a voltage comparison circuit 21, a trigger circuit 22, a timing circuit 23, and an adjustment switch circuit 24. The signal amplification circuit 20 includes a minimum circuit based on an operational amplifier LM358, the voltage comparison circuit 21 includes a minimum circuit based on a voltage comparator LM393, the trigger circuit 22 includes an RS flip-flop, the timing circuit 23 includes a minimum system based on a 555 timer chip, and the adjustment switch circuit 24 includes a second transistor switch. The base of the second transistor switch is coupled to the output terminal of the timing circuit 23, the collector of the second transistor switch is energized, and the emitter of the second transistor switch is connected to the servo motor 18 and then grounded.

[0043] Distance sensor 19 is installed on the hull located on the opening side. Distance sensor 19 is used to detect the distance between itself and the hatch 6 and to feed back a distance signal. The input terminal of signal amplification circuit 20 is coupled to the output terminal of distance sensor 19. Signal amplification circuit 20 is used to amplify the distance signal and output it. The input terminal of voltage comparison circuit 21 is coupled to the input terminal of signal amplification circuit 20. Voltage comparison circuit 21 outputs a comparison signal after the voltage of the amplified distance signal is greater than the voltage of the preset distance reference signal. The input terminal of trigger circuit 22 is coupled to the output terminal of voltage comparison circuit 21. Trigger circuit 22 outputs a trigger signal after responding to the comparison signal. The input terminal of timing circuit 23 is coupled to the output terminal of trigger circuit 22. Timing circuit 23 starts timing after responding to the trigger signal and outputs a timing signal within the timing period. Adjustment switch circuit 24 is connected in series between servo motor 18 and power supply. Adjustment switch circuit 24 controls servo motor 18 to be powered on after responding to the timing signal.

[0044] In actual operation, when people need to leave the cabin and go to the outside world, they can manually swipe the card reader module 12 in the smart card door lock using an IC card or magnetic card. The card reader module 12, which is actually an MFRC522 contactless card reader, can transmit a signal to the control module 11, which is actually an STM32 microcontroller, after reading the IC card or magnetic card. After reading the signal, the control module 11 can transmit a signal to the ULN2003 driver board and the delay circuit 14 in the stepper motor 13. The ULN2003 driver board will control the 28BYJ4 stepper motor to work, thereby releasing the detachable connection between the cabin door 6 and the cabin body. Specifically, a lock seat that cooperates with the smart card door lock is fixedly connected to the cabin body.

[0045] After disconnecting the hatch 6 from the cabin, people can choose to open the hatch 6 manually. That is, by applying force to the hatch 6 through the handle 7, the hatch 6 will slide within the upper and lower tracks 5, thereby opening the hatch 6.

[0046] If the door is not opened manually, the delay circuit 14 receives a signal from the control module 11. The delay module will continuously receive the signal and charge the capacitor. After the capacitor is fully charged, a delay signal is sent to the drive switch circuit 15, which enables the base of the first transistor switch in the drive switch circuit 15 to receive the signal. This makes the collector and emitter of the first transistor switch conduct, energizing the relay in the drive switch circuit 15. This causes the normally open relay switch controlled switch circuit 16 to close, allowing the signal from the control module 11 to be sent to the motor drive circuit 17. The motor drive circuit 17 then controls the servo motor 18 to work. The servo motor 18 rotates the take-up roller, which in turn drives the pull rope to wind up, thus pulling the door 6. This causes the door 6 to slide within the upper and lower tracks 5, allowing the door 6 to open automatically.

[0047] Furthermore, it is important to note that during this process, the distance sensor 19 detects the distance between itself and the hatch 6 and feeds back a distance signal. This distance signal is amplified by a signal amplifier and then sent to the voltage comparison circuit 21. The voltage comparison circuit 21 can only output a comparison signal if the voltage of the amplified distance signal is greater than the voltage of a preset distance reference signal. This means that the distance between the distance sensor 19 and the hatch 6 is greater than a threshold, indicating that the hatch 6 has not been opened. The comparison signal is then sent to the trigger circuit 22 to trigger it, and a low-level trigger signal is output. In fact, the timing module of the minimum system based on the 555 timer chip needs a low-level trigger signal to start timing. During the timing period, a timing signal is output to the adjustment switch circuit 24 of the second transistor switch. Then, the base of the second transistor switch receives the timing signal, and the collector and emitter of the second transistor switch are turned on, ensuring that the power supply provides power to the servo motor 18. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model shall be included within the protection scope of this utility model.
