[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figure 1The utility model provides a circuit diagram of a docking station dual-axis drive controller, which includes a control module 101 and a drive module 102, and the control module 101 and the drive module 102 are located on the same circuit board, the control module 101 is used to send control instructions, and the drive module 102 controls the movement of the motor according to the control instructions. The control module and the drive module are integrated into an integrated controller, and the control end signal is directly connected to the drive module, which reduces the occurrence of signal interference problems, reduces the wiring workload, reduces the production cost, effectively improves the debugging efficiency, and improves the life and stability of the equipment.
[0021] like Figure 4 As shown, the 40th pin pwm1, the 39th pin pwm3, the 38th pin pwm5, and the 3rd pin pwm7 of the control module are respectively connected to the driving module.
[0022] like Figure 2 As shown, the drive controller also includes a power module, which is connected to the control module and is used to supply power to the control module.
[0023] The power module is used to convert DC24V into 12V and 3.3V DC power inside the PCB.
[0024] Optionally, the drive controller further includes a communication module, which is connected to the control module and is used to set a communication address of the drive module by adjusting a dip switch.
[0025] The 59th pin USART_RX, the 58th pin USART_TX, and the 57th pin 485R / D_EN of the control module are connected to the communication module.
[0026] Optionally, the module includes an RS485 communication unit or an RS232 communication unit, and the RS485 communication unit or the RS232 communication unit is used to communicate with the control module.
[0027] Serial communication refers to a communication method that can transmit data in bits using only one receiving line and one transmitting line. Although serial communication is slower than parallel communication that transmits in bytes, the serial port can transmit data using only two lines.
[0028] Serial communication modes include simplex, half-duplex and full-duplex. Simplex mode data transmission only supports data transmission in one direction. Half-duplex mode allows data transmission in both directions, but only in one direction at a time. It is actually a simplex communication with switching direction. It does not require independent receiving and transmitting ends, and the two can be combined into one port.
[0029] In the RS232 communication mode, a connection is established between the "DB9 interfaces" of two communication devices through serial port signal lines. The "RS-232 standard" is used to transmit data signals in the serial port signal lines. The original numbering system of the D-type or D-subminiature (D-shaped subminiature) connector uses D as a prefix (naming its name as a series), and then selects A, B, C, D, or E according to the housing size. The last digit represents the number of pins.
[0030] RS232 generally uses a DB9 interface. Since the receive and transmit signals (RXD and TXD) between two communication devices should be cross-connected, the connection method of the receive and transmit signals of the DB9 female head at the modem end is generally opposite to that of the male head.
[0031] RS-485 uses a half-duplex communication mode, has 2 signal lines, and operates in the half-duplex mode, and is often used in bus networks.
[0032] Optionally, the drive controller further includes a storage module. The storage module is connected to the control module. The storage module is used to store the device address, current, input function selection, output function selection, maximum speed, acceleration and deceleration time, and working mode corresponding to the address byte.
[0033] The 8th pin I2C1_SCL and the 9th pin I2C1_SDA of the control module are connected to the storage module.
[0034] Optionally, the storage module includes one of a coil status register, a discrete input status register, a holding register, or an input register.
[0035] Coil register: It can actually represent a digital quantity. The coil operation bit (bit) corresponds to a switch signal for each bit, that is, (0 / false, I / true). Each byte can represent 8-bit switch signals. The coil register supports reading and writing. The function codes of Modbus can perform read and write operations on single or multiple coils, which is actually operating on the bits of the byte. The corresponding function codes are: 0x01 0x05 0x0f;
[0036] Discrete input register: The discrete input register is equivalent to the read-only mode of the coil register, and its function is basically the same as above, except that it cannot be written. So the function code is simply the read 0x02;
[0037] Holding register: The holding register operates on bytes. Every two bytes correspond to a register and support reading and writing. There are about three corresponding function codes: 0x03 0x06 0x10;
[0038] Input register: This is similar to the holding register, but only supports reading and not writing. A register address occupies two bytes of space, that is, 16 bits. The corresponding function code is just 0x04;
[0039] Optionally, the drive controller further includes an anti-interference resistor, and the anti-interference resistor is connected to the control module.
[0040] Optionally, the anti-interference resistor is a 120Ω terminating resistor.
[0041] Using RS485, adopting the balanced transmission and differential reception method, so it has the ability to suppress common-mode interference; the PCB is also matched with a terminating resistor (see the red marking) selection to reduce signal reflection and effectively improve the anti-interference ability of communication.
[0042] Such as Figure 3 As shown, in the embodiment of the present application, the communication interface reserves RS485 / 232, and a 120Ω terminating resistor is set on the board, which can effectively improve the anti-interference ability of long-distance communication. The communication protocol selects the standard MODBUS-RTU protocol, and the setting of the drive communication address is adjusted by a 1-5-bit DIP switch, and its address adjustable range is 0-31 (where the 0 address is reserved for the system). By setting parameters such as the device address, current, input function selection, output function selection, maximum speed, acceleration and deceleration time, and working mode corresponding to each address byte in the MODBUS register, the control of the specified device can be realized.
[0043] Optionally, the control module is a single-chip microcomputer chip.
[0044] Optionally, the control module is also connected to the host computer and conducts data communication with the host computer through the MODBUS-RTU protocol.
[0045] The embodiment of the present application adopts the RS485 communication method, effectively solving the disadvantages of the traditional stepper driver control method being single, the communication distance being short, and the anti-interference ability being poor; the protocol uses the standard MODBUS-RTU protocol, which can realize the diversified adjustment of parameters such as device address, current, input function selection, output function selection, maximum speed, acceleration and deceleration time, and working mode. The integrated solution of the control board and the driver saves costs, improves stability, reduces the wiring difficulty, reduces the debugging workload, and greatly improves the device life and stability.

The traditional control board and driver installation mode is replaced by the drive and control integrated control board of the docking station.
