One end of the three medicine bin partitions are connected to the medicine outlet bin door shaft, and the angle between two adjacent medicine bin partitions is 120 degrees. A control circuit of an intelligent household medicine box comprises a control chip and a Bluetooth module, wherein RX and TX pins of the Bluetooth module are connected to D0 and D1 pins of the control chip, DIR and PUL pins driven by a stepper motor are connected to D4 and D5 pins of the control chip, a servo responsible for an emergency medicine outlet is connected to D10 pin of the control chip, a servo responsible for the medicine outlet is connected to D11 pin of the control chip, an OLED display is connected to D20 and D21 pins of the control chip, a suction pump motor drive module is connected to D12, D22 and D23 pins of the control chip, RST, DAT and CLK pins of a clock module are respectively connected to D22, D23 and D24 pins of the control chip, and RX and TX pins of a voice module are connected to D44 and D45 pins of the control chip.

[0006] A control method for a control circuit of an intelligent household medicine box comprises the following steps:

[0007] Step 1: The user inputs the time type for taking medicine: set the time to remind the patient to take medicine according to the patient's needs, put different medicines or the same medicines in the eight compartments, that is, put different medicines or the same medicines in the box cavity 1, box cavity 2, box cavity 3, box cavity 4, box cavity 5, box cavity 6, box cavity 7, and box cavity 8 respectively, and set the number of medicines to be taken from the eight lower box cavities in turn each time; Step 2: The medicine storage box is on standby;

[0008] Step 3: Include the following steps:

[0009] a. When it is time to take medicine, the stepper motor rotates, and the output shaft of the stepper motor drives the medicine storage box to rotate, and the lower box cavity where the medicine to be taken is located is rotated to the lower part of the suction pump, and the suction pump extends to suck the medicine, and the suction pump retracts, and the stepper motor rotates 20 degrees, and the suction pump stops working, and the medicine will fall into the medicine outlet bin 1;

[0010] b. Then rotate the output shaft of the stepper motor 54 to drive the medicine storage box 4 to rotate, and rotate the lower box cavity where the medicine to be taken is rotated to the lower part of the suction pump, and the suction pump extends to suck the medicine, and the suction pump shrinks, and the stepper motor rotates 20 degrees, and the suction pump stops working, and the medicine will fall into the medicine storage chamber 1;

[0011] c. Repeat steps a and b above until all the medicine is taken;

[0012] Step 4: Determine whether all the medicines to be taken out have been taken out. If not, proceed to step 3. If all the medicines have been taken out, proceed to step 5. Step 5: The buzzer of the medicine storage box 4 sounds to remind the patient to take the medicines.

[0013] Step 6: If the patient does not take the medicine within the specified time after waking up, send a text message to the guardian's mobile phone to remind him to take the medicine.

[0014] A control method for a control circuit of an intelligent household medicine box comprises the following steps:

[0015] Step 1: Put the tablets into the medicine outlet bin 1 in advance;

[0016] Step 2: Medicine box standby;

[0017] Step 3: The emergency medicine button is pressed;

[0018] Step 4: The pills in the emergency medicine box pop out;

[0019] Step 5: The medicine box rings and sends a message to the guardian;

[0020] Step 6: Determine whether the pill has been taken away within two minutes. If so, proceed to step 2; if not, proceed to step 7.

[0021] Step 7: Dial the guardian for reminder.

[0022] Beneficial effects of the present invention: The medicine box is provided with a detection unit to detect whether the user has taken the medicine on time within the prescribed time. When it is detected that the user has taken the medicine on time, the display unit will prompt the user that the medicine has been taken, so as to avoid repeated medication. Through the display unit, the user can easily obtain information such as the current medication situation, medication time and medication information. Now most families have a small medicine box, but this medicine box basically only stores medicines and lacks monitoring of the storage environment and necessary reminders. Moreover, it may be used improperly, which is a hidden danger for families with children. The present invention provides an intelligent household medicine box that can realize functions such as automatic door closing, timed reminders and monitoring of the storage environment.

[0056] The control microcontroller used in this product is Arduino MEGA 2560 pro, which has the advantages of low power consumption, high performance, compact size, and multiple serial ports. It can not only communicate with other devices such as mobile phones through the communication module, but also directly control the hardware modules in the product through the serial port.

[0057] Mega 2560 has 54 available digital signal serial ports, numbered D0 to D53.

[0058] The RX serial port D0 and the TX serial port 1 are connected to the HC-06 Bluetooth module, where D0 is connected to the TX port of the HC-06 end, and D1 is connected to the RX port of the HC-06 end. After being connected, the microcontroller can send and receive information through the Bluetooth module.

[0059] D2 and D3 are used to connect to the micro-stepping motor driver that drives the stepper motor slide to control the lifting of the medicine inhalation port. D2 is connected to the DIR pin of the driver, and D3 is connected to the PUL pin of the driver. When controlling the movement of the slide, D2 controls the forward and reverse rotation of the stepper motor by giving two different levels of high and low to DIR, and the D3 pin inputs a specific current pulse to the PUL pin. The frequency and duration of the pulse determine the angle and speed of the stepper motor.

[0060] The D3 and D4 pins are connected to the TB6600 high-power stepper motor driver module, which is used to drive the 42 stepper motor in the center of the medicine box to drive the medicine box to rotate. D3 is connected to DIR, and D4 is connected to PUL. The principle is the same as D2 and D3.

[0061] The D10 and D11 pins are connected to the mini analog servos that control the opening and closing of the medicine outlet and the emergency ammunition compartment respectively. By sending a 1500-2500ms electrical level through the serial port, the servos can rotate 0°-180°.

[0062] D12 is connected to D22 and D23 with the L298N driver module, which is used to control the DC motor on the suction pump. By controlling the speed of the motor, the suction force of the suction port can be adjusted. The D12 serial port is connected to the pwm input serial port on the module, and D22 and D23 are connected to the IN1 port and IN2 port on the module respectively. The microcontroller can make the DC motor forward, reverse, and lock by passing different high and low levels to IN1 and IN2 respectively. Then, through the D12 serial port, the analog signal of 0-255 frequency is input to the pwm input serial port on the module to control the different speeds of the motor.

[0063] The serial ports of D20 and D21 are connected to a 1.3-inch SSD1306 OLED screen. D20 is connected to the SCL pin of the screen, and D21 is connected to the SDA pin. The data and working status of the medicine box are displayed in real time through 1306, allowing users to better interact and adjust settings.

[0064] The D22, D23, and D24 pins are connected to the DS1302 clock module. The three pins are connected to the RST, DAT, and CLK pins on the module. The function of this module is to provide the module with accurate current time so that the medicine box can realize functions such as timing medicine collection. Therefore, even if the microcontroller is powered off, the button battery of the module will still power the module to ensure the accuracy of the time.

[0065] The D25 and D26 pins are connected to the ESP8266 wifi module, which can connect to other LANs so that the medicine box can obtain information from the network and realize the Internet of Things function.

[0066] The D27 and D28 pins are used as the leveling button switches for the stepper motor slide and the medicine box stepper motor respectively. The buttons are paddle switches, and the switches are connected to the 5V and corresponding pins of the microcontroller. When the switch is pressed, the 5V is short-circuited with the corresponding pin, so that the microcontroller detects that the pin level is increased.
