[0021] To make the objectives, technical solutions, and advantages of the utility model clearer, the technical solutions in the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the utility model.

[0022] Therefore, the following detailed description of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0023] Embodiment 1

[0024] This embodiment discloses a DCU driver. As a basic implementation scheme of the present utility model, it includes a MUC chip, a power conversion unit, a motor drive unit, a Hall acquisition circuit, an encoder acquisition circuit, a limit detection circuit, a motor port, a Hall port, an encoder port, a power port, a limit signal port, and a UART communication port.

[0025] Among them, the power conversion unit includes a power input terminal and several power output terminals; the power input terminal of the power conversion unit is electrically connected to the power port, and each power output terminal is respectively connected to the MUC chip, the motor drive unit, the Hall acquisition circuit, the encoder acquisition circuit, and the limit detection circuit. Thus, in actual use, an external power source is connected to the DCU driver through the power port, and the power conversion unit is used to convert the externally connected power source into the working power required by functional units such as the MUC chip, the motor drive unit, the Hall acquisition circuit, the encoder acquisition circuit, and the limit detection circuit in this technical solution.

[0026] Furthermore, the motor drive unit is respectively communicatively connected to the motor port and the MUC chip. Thus, a platform door motor device is externally connected through the motor port, and the motor drive unit drives the platform door motor device to work according to the instructions issued by the MUC chip. At the same time, the working signal of the platform door motor device is collected through the motor port and sent back to the MUC chip for subsequent logical control processing by the MUC chip.

[0027] Furthermore, in the platform door system in the field of rail transit, generally, a Hall sensor is used to monitor the position of the rotor of the platform door motor device, and an encoder is used to monitor the operating state of the platform door motor device. A DCU driver proposed in this technical solution is provided with a Hall acquisition circuit and an encoder acquisition circuit, and the Hall port is communicatively connected to the MUC chip through the Hall acquisition circuit, and the encoder port is communicatively connected to the MUC chip through the encoder acquisition circuit. In actual use, the Hall port and the encoder port can be used alternatively. The Hall sensor or the encoder will generate a square wave signal with a specific time sequence, and the relevant interface acquisition circuit (i.e., the Hall acquisition circuit or the encoder acquisition circuit) collects this square wave signal and sends it to the MUC chip, and the MUC chip calculates the real-time position of the movable door according to the corresponding square wave signal. Specifically: the DCU driver can externally connect a Hall sensor or an encoder through the Hall port or the encoder port.

[0028] Further, the limit signal port is communicatively connected to the MUC chip through a limit signal detection circuit. In the field of rail transit, limit switches are widely used as physical switches for detecting the closing and opening positions of sliding doors, and an optoelectronic trigger switch or a mechanical trigger switch can be selected according to requirements. When the limit switch is triggered, the limit signal detection circuit obtains the limit switch conduction signal through the limit signal port and makes corresponding output instructions. The MCU chip performs subsequent relevant logic control processing based on the limit switch conduction signal obtained by the limit switch detection circuit.

[0029] Furthermore, the UART communication port is communicatively connected to the MUC chip for realizing signal transmission with the DCU controller. In this way, the DCU driver can execute the control commands issued by the DCU controller, and the DCU driver can upload relevant collected signals to the DCU controller.

[0030] In summary, the technical solution proposed in this document is a DCU driver specifically customized for the platform door system, which highly integrates an MUC chip, a motor drive unit, a Hall acquisition circuit, an encoder acquisition circuit, and a limit detection circuit, and supports the acquisition function of various signals related to the operation of the platform door motor equipment. On this basis, only an embedded software adapted according to requirements needs to be developed to achieve the motion accuracy and control of the opening and closing door curves of the platform door to meet the requirements of different application scenarios. Among them, different application scenarios involve different platform types (such as high-speed rail platforms and subway platforms), different platform door types (such as full-height platform doors and half-height platform doors), different platform door weights and sizes, etc.

[0031] In addition, based on the characteristics of the high integration of the DCU driver proposed in this technical solution, when it is applied to the platform door system, it can reduce the complexity of the platform door system, which is of great significance for facilitating system maintenance, reducing system costs, and improving system reliability and safety.

[0032] Embodiment 2

[0033] This embodiment discloses a DCU driver. As a preferred implementation of the present invention, based on Embodiment 1, its power conversion unit includes a protection / filter module and a DC24V drive power module for accessing the motor drive unit, and further includes a DC24V system power module, a DCDC5V conversion circuit, an LDO3.3V conversion circuit, and a DC3.3V reference circuit that are electrically connected in sequence. Among them, the protection / filter module is connected to the DC24V system power module through diode A and to the DC24V drive power module through diode B; the LDO3.3V conversion circuit and the DC3.3V reference circuit are respectively connected to the MUC chip.

[0034] Based on the composition structure of the above power conversion unit, an external DC24V power supply is connected to the power conversion unit through the power interface to input 24V direct current into the protection / filter module. The protection / filter module includes a protection circuit and an EMI filter circuit, which play the roles of overcurrent protection, reverse connection protection, surge and electrostatic protection, and power supply filtering.

[0035] In actual situations, since the platform screen door motor equipment will experience rapid changes in the driving power network voltage (including undervoltage and overvoltage, etc.) during operation, the protection / filter module includes two DC24V outputs. One output flows through diode A to the DC24V system power supply module, and the other output flows through diode B to the DC24V driving power supply module. Diode A and diode B play the role of isolating the two DC24V outputs. The DC24V driving power supply module is used to supply DC24V power to the motor driving unit and ensure the power supply stability at the same time; the DC24V system power supply module supplies DC24V power to the DCDC5V conversion circuit and ensures the power-on stability at the same time. In this way, by separating the two power supplies of the DC24V system power supply and the DC24V driving power supply, based on the existence of the DC24V driving power supply module and the DC24V system power supply module, the DC24V driving power supply and the DC24V system power supply are completely independent, which can ensure the stability of the DC24V system power supply and thus guarantee the stable operation of the DCU driver.

[0036] The DCDC5V conversion circuit converts 24V direct current into 5V direct current, which can supply DC5V power to the Hall acquisition circuit and the coding acquisition circuit, and at the same time input 5V direct current into the LDO3.3V conversion circuit. The LDO3.3V conversion circuit (low dropout linear voltage regulator circuit) converts 5V direct current into 3.3V direct current and leads it to the MCU chip and the DC3.3V reference circuit respectively. Among them, during the operation of the DCU driver, the interference of the external circuit will cause fluctuations in the 3.3V direct current input to the MCU chip by the LDO3.3V conversion circuit, while the DC3.3V reference circuit provides a stable reference voltage for the ADC function of the MCU chip.

[0038] This embodiment discloses a DCU driver. As a preferred implementation of the present utility model, that is, based on Embodiment 1 or 2, the power port and the limit signal port are integrated in interface part A, and the motor port, the Hall port, and the encoder port are integrated in interface part B. Based on this, this technical solution greatly reduces the interface terminals of the DCU driver, which is not only beneficial to reducing the product volume, but also beneficial to quickly completing installation, debugging, maintenance, and other work.

[0039] Embodiment 4

[0040] This embodiment discloses a DCU driver. As a preferred implementation of the present utility model, that is, based on Embodiment 2, its motor drive unit includes a pre-drive IC module, a MOS array module, and an energy-dissipating circuit; the MUC chip is sequentially connected to the motor port through the pre-drive IC module and the MOS array module; the pre-drive IC module, the MOS array module, and the energy-dissipating circuit are respectively electrically connected to the DC24V drive power module; the energy-dissipating circuit is communicatively connected to the MUC chip.

[0041] Based on the structure of the above motor drive unit, the working principle of this technical solution is as follows:

[0042] After the MCU chip receives relevant input signals from the DCU controller or its functional modules (such as Hall sensors, limit switches, and editors, etc.) through corresponding ports, the MCU chip calculates the operating parameters required for the platform door motor device through the control algorithm included in its built-in embedded software. The operating parameters include the enable signal of the pre-drive IC module, the duty cycle of the complementary square wave signal (PWM signal), the direction control signal, and so on.

[0043] According to the calculated operating parameters, the MCU chip sends a control signal (a complementary square wave signal) to the pre-drive IC module through the corresponding communication connection port. After receiving the complementary square wave signal, the pre-drive IC module converts the complementary square wave signal into a motor drive signal (also a PWM signal) according to the operating parameters involved in the complementary square wave signal.

[0044] The MOS transistor (MOSFET) is a commonly used switching element in motor drives, which can be quickly turned on and off to control the current of the motor. The MOS array module consists of multiple MOS transistors. In the UVW phase lines of the motor operation circuit, each phase is separately controlled by a MOS transistor. Based on this, the pre-drive IC module sends motor drive signals to the MOS array module to control the on and off of the corresponding MOS transistors, and further realizes the control of the current, rotation direction, and rotation speed of the platform door motor device. Specifically: The platform door motor device is a three-phase motor, and the UVW phase lines are the three phase lines of the three-phase motor, which are respectively connected to the three windings of the three-phase motor. By applying different voltages and currents on these three phase lines, the operation control of the three-phase motor can be realized. Based on this, when the MOS array module receives the instruction (i.e., the motor drive signal) sent by the pre-drive IC module, the MOS transistors inside it determine whether to turn on or off according to the duty cycle of the PWM signal. In this way, the MOS array module outputs corresponding voltages and currents to the UVW phase lines according to the on and off conditions of the MOS transistors inside it, so as to drive the platform door motor device to operate in the specified direction and speed. The principle involved is: After applying voltages and currents to the UVW phase lines, the magnetic field inside the motor will change, interact with the magnetic field of the motor rotor, generate a rotational torque, and make the motor rotate; further, by changing the duty cycle of the PWM signal to change the combination of voltages and currents on the UVW phase lines, the rotation direction, speed, and torque of the motor can be controlled.

[0045] Furthermore, in actual application, independent current sampling resistors and corresponding sampling circuits are respectively set on the three UVW phase lines, and are sampled by the current sampling interface built in the pre-drive IC module, and then output to the ADC sampling port of the MCU chip after calculation. The MCU chip is used for real-time sampling and calculation to obtain information such as the instantaneous current of the UVW phase lines.

[0046] Furthermore, a corresponding protection circuit (such as overcurrent protection and overheat protection, etc.) is set in the pre-drive IC module. When corresponding circuit faults such as overcurrent and overheat occur in the motor drive unit, the pre-drive IC module will timely send the fault signal to the MUC chip, so that the MUC chip and / or system management personnel can make corresponding emergency control measures in time to ensure the safety of the platform door motor device and the platform door system, and further prevent safety accidents from occurring.

[0047] In addition, when the platform door motor device brakes or is pushed by the following flight, it will cause abnormal voltage energy in the bus (i.e., the DC24V drive power supply). This technical solution sets an energy dissipation circuit to release this abnormal voltage energy.

[0048] Embodiment 5

As a preferred implementation of the present utility model, that is, based on Embodiment 1, 2, 3, or 4, it further includes a hardware configuration module, and the hardware configuration module is communicatively connected to the MUC chip. In this technical solution, by setting the hardware configuration module, it is used to perform hardware configuration on the working mode, IDriver current, Vds protection voltage, and Gain gain of the pre-drive IC module. Specifically, by adjusting the pull-up resistor and / or pull-down resistor inside the hardware configuration module and changing the corresponding resistance values, various configuration values can be configured.

Later over-temperature protection measures include stopping operation and reporting faults, etc.

Based on the conventional technical means in the electrical field, relevant detection circuits are set for the signals supporting self-check and connected to the MCU chip to achieve self-check. For example: for the self-check of the hardware configuration module, the adjusted pull-up resistor and / or pull-down resistor inside it are correspondingly controlled to the input end of the pre-drive IC module and connected to the ADC detection port of the MCU chip. By detecting the different voltage values at this position, it can be determined whether the configuration result is correct.
