The magnetic suspension earth base circuit is responsible for suspending the whole earth model, and the circuit in the earth bracket is responsible for controlling the forward rotation, the reverse rotation, the rest, the light and other functions of the earth model. The circuitry within the earth support is in communication with the master processor on the central control circuit 100 through a wired serial interface.

The magnetic suspension earth base mainly comprises a Hall sensor, a magnetic field regulating circuit, a bottom fixed magnet and a floater. When the two magnets are in contact, the like poles repel each other and the opposite poles attract each other. When the force-bearing area of the magnetic field at the bottom end is large enough and the magnetic field at the top end is small, the Hall sensor senses a magnetic field position signal and then adjusts the size of the artificial magnetic fields at the upper part, the lower part, the left part and the right part in real time to keep the magnetic fields of the floater in four directions to be relatively balanced, and when the magnetic fields of the floater are balanced, the floater can be suspended in the air. The magnetic suspension earth base is additionally provided with a signal acquisition circuit which can detect whether the model is in a suspension state or not in real time, a lead is connected to a central control circuit 100 board from an LED state indicator lamp of the magnetic suspension earth base, and the state of the earth model can be deduced by acquiring signals of the LED lamp.

The earth support circuit consists of 5 units, namely a 5V power supply circuit, a fourth processor, a second stepping motor driving circuit, a wired communication interface and a light control circuit. The 5-element circuit was integrated on a 32mm by 28mm circuit board placed in the void of a wooden earth support. A schematic diagram of the 5V power supply circuit is shown in fig. 23, the 5V power supply circuit mainly provides working voltage for the fourth processor, the second stepping motor driving chip and the light control circuit, and a power supply of the whole bracket circuit is accessed from an ISP interface to provide working voltage for the fourth processor, the second stepping motor driving chip and the light control circuit; taking electricity from a 5V power expansion port on the central control circuit 100 board; because of the structural reason of whole magnetic suspension science and technology goods of furniture for display rather than for use, need increase the magnetic ring for getting the electric circuit and just can guarantee that support circuit's 5V operating voltage is not disturbed by the magnetic field. As shown in fig. 24, the model of the fourth processor is STC15W408AS, and the processor mainly provides a working timing sequence for the stepping motor driving chip to control the on and off of the LED at 2 positions on the bracket; the processor on the bracket circuit board is in wired serial port communication with the processor on the central control circuit 100 board; when a user clicks on the HMI touch screen, the processor on board the central control circuit 100 will transmit control commands to the processor on the cradle circuit board through the wired serial port. The second stepping motor driving circuit is mainly responsible for forward transmission and reverse rotation of the whole earth model; as shown in fig. 25, the motor driver chip is model ULN2003, and the processor provides the operation timing. The stepping motor drives a round wood chip, three strong magnets (N poles) are arranged on the wood board, the three magnets and three magnets (S poles) on the earth model are in three vertical lines, when the round wood chip rotates, the wood chip drags the earth model to rotate due to the fact that the magnets attract each other in opposite directions, and when the wood chip does not move, the earth model is still suspended in the air. The circuit board in the rack and the main control processor on the central control circuit 100 board are communicated by a wired serial port, as shown in fig. 26, one end of each of 2 wires is connected with the rack end and connected with the ISP port, and the other end is connected with the serial port 3 of the main control processor; the ISP port has two functions, one being the power input to the rack circuit and one being the communications connection port. As shown in fig. 27, the light control circuit uses an L9110S switch chip to control the on/off of 2 LEDs, and the 2 LEDs increase the light effect for the earth model when being turned on; an IA pin of the L9110S is connected with an IO pin of the processor, when the pin is at a high level, the LED is turned on, and when the pin is at a low level, the LED is turned off; the D2 diode serves as the current-limiting resistor of the LED, the passing voltage is reduced after the diode is conducted, and the L9110S switch chip has a voltage drop of 0.7V, so that the LED does not need the current-limiting resistor in the circuit and can work normally.
