It is to be understood that the described embodiments are merely exemplary of a portion of the invention and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, shall fall within the protection scope of the present invention. In addition, the terms "comprises" and "comprising," and any variations thereof, in the description and claims of this invention, are intended to cover a non-exclusive inclusion, such that a process, method, apparatus, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In an embodiment of the present invention, an integrated automatic door control device is provided, as shown in fig. 1, the control device includes a motor, a power management unit, a power driving unit, a satellite sealing relay, and an MCU/DSP control unit (referred to as a control unit for short).
The motor is configured to drive operation of the automatic door. In this embodiment, the motor is a permanent magnet synchronous motor, and the permanent magnet synchronous motor and the control system thereof have the advantages of low rotating speed, large torque, high efficiency, high control precision, low noise, small vibration, low energy consumption and the like.
The power management unit is configured to provide power to the control device. In this embodiment, as shown in fig. 2, the power management unit includes a rectifying circuit, a power factor correction circuit (PFC), a charging/discharging current buffer control circuit (buffer circuit for short), an over-voltage and over-current protection circuit (protection circuit for short), and a filter circuit. The rectifier circuit is configured to convert single-phase alternating current (the range of single-phase alternating current of the present embodiment is AC60 to AC270V) into single-phase direct current, the power factor correction circuit is an active boost circuit, and the power factor correction circuit is configured to control an input current waveform so that voltage and current are in phase. The buffer circuit comprises a buffer resistor, the buffer circuit is configured to buffer the charging current and the discharging current, and when the charging voltage is higher than a preset voltage threshold value, the control unit controls a loop in which the buffer resistor is located to be disconnected. The protection circuit is configured to protect the bus capacitor, and the control unit controls the power management unit to cut off power supply when the input voltage of the bus capacitor is higher than a preset voltage threshold value.
In one embodiment of the invention, the rectifier circuit functions to convert a single-phase ac voltage to a unidirectionally pulsating dc voltage. The rectifying circuit mainly comprises a rectifying diode. The average rectifying current of the rectifying diode in this embodiment is 10A, and the maximum reverse operating voltage VR is 800V. The power factor correction circuit (PFC) mainly has the functions of enabling the phases of voltage and current to be the same, enabling a load to be similar to a resistance, reducing the load of a power grid and reducing reactive power consumed by a user. Implementations of PFC are classified into passive and active. In this embodiment, an active boost circuit structure is adopted, and as shown in fig. 3, an inductor L1, a diode D1, and a driving transistor Q1 are added in the implementation manner. The principle is as follows: when Q1 is turned on, the voltage across the inductor is the same as the voltage across capacitor C1, at which time C1, L1, and Q1 form a loop, and C1 charges the inductor and the current continues to rise. When the PFC control chip turns off Q1, the charging ends. When Q1 turns off, the inductor voltage inverts and adds C1 to the voltage, starting to discharge the output through diode D1, which charges capacitor C2. The control signal of Q1 needs to sample the loop voltage and current for feedback control, and controls the on and off of Q1, so as to achieve the purpose of current waveform shaping.
In one embodiment of the invention, the buffer circuit is used for connecting a current-limiting power resistor in series in the early stage of power-on during startup so as to prevent the energy-storage filter capacitor from being damaged by overlarge charging current. When the charging voltage is increased to a safe voltage value, namely the driving motor is driven and controlled, the current-limiting power resistor loop is cut off, and the capacitor is directly charged and discharged.
In one embodiment of the invention, for the overvoltage and overcurrent protection circuit, when the input voltage of the filter bus capacitor is monitored to be higher than a preset value, the supply of an input power supply is cut off, and the bus capacitor is protected from overvoltage damage. When the current of the power loop is monitored to be larger than the preset value, the supply of the input power supply is cut off.
The power driving unit is electrically connected with the power management unit, as shown in fig. 4, the power driving unit includes a three-phase circuit, and the star sealing relay is connected in the three-phase circuit of the power driving unit and the motor. The three-phase circuit of the power driving unit comprises a capacitor (C2 in fig. 4), three groups of power tubes (T1-T6 in fig. 4) and a sampling resistor (R1 in fig. 4), wherein two ends of the capacitor are respectively connected to two ends of a bus voltage; the three groups of power tubes are connected to two ends of a bus voltage, the three groups of power tubes are connected to three phases of the motor in a one-to-one correspondence mode, and the normally open contact of the star sealing relay is connected to the three groups of power tubes and each group of branches of the motor, so that when the normally open contact of the star sealing relay is closed, the braking electromagnetic force is generated inside the motor; the driving signal of the power tube is configured to be supplied by SVPWM; one end of the sampling resistor is electrically connected with the output end of the power tube, the other end of the sampling resistor is electrically connected with the negative end of the bus voltage, and the sampling resistor is configured to provide a real-time current value required by SVPWM. The three-phase circuit is electrically connected with three phases of the motor respectively, and the power driving unit is configured to drive the motor to work through the three-phase circuit. It should be noted that the power transistor is an IGBT or an NMOS or an integrated power module, and the specific type is determined according to actual requirements, which does not limit the protection scope of the present invention.
In an embodiment of the present invention, the power driving unit includes six IGBT or NMOS transistors T1-T6, or an integrated power module is adopted, or a plurality of separate devices may be adopted, which does not limit the protection scope of the present invention. As shown in FIG. 4, the two terminals of the capacitor C2 are bus voltage, the positive terminal is P, and the negative terminal is N. The three-phase inversion upper bridge driving power tubes are T1, T2 and T3, and the lower bridge driving power tubes are T2, T4 and T6. T1 and T2 make up a pair, T3 and T4 make up a pair, T5 and T6 make up a pair, these three pairs drive the U, V, W phases of the motor respectively. The T1-T6 tubes are driven with a PWM waveform.
In the embodiment, an SVPWM vector algorithm is used for independently controlling the torque current and the flux electric quantity of the motor. The SVPWM control needs to sample the real-time current value of the motor, the most direct method is to sample any two phases of the three-phase current of the motor U, V, W, because of the star connection mode, the vector sum of the three-phase current is 0, as long as the current values of the two phases are known, the current value of the third phase can be known, or the output end of the three-phase low-end power tube is connected with three sampling resistors (or current sensors) to detect the current, the selection of the sampling resistors needs to consider the stability of the resistors, and the sampling resistors need to have low temperature drift coefficients, and can not affect the resistance value change when working for a long time. The resistance value of the sampling resistor is small enough to ensure that the power consumption generated on the resistor reaches a negligible program. The values of the three comparators are compared in real time in the interruption of PWM underflow, and are influenced by factors such as a sampling switch, an A/D sampling window, the high level holding time of a lower bridge arm and the like, so that the sampling value of the smaller path of the comparator is abandoned after current sampling, the other two phases of the path are synthesized according to the condition that the sum of the three phases is 0, and the synthesized current is more consistent with the output current of the inverter module and reflects the real current value of the load. In order to reduce the cost of circuit design, the present embodiment combines three sampling resistors into one sampling resistor R1, as shown in fig. 4, and this one-resistor current sampling mode is well suited to a low-power motor drive control mode. Because only one sampling resistor is needed, a single-resistor current reconstruction technology is needed to calculate three-phase current, and the basic principle is that in SVPWM control, when a non-0 basic vector is used, the phase current of a motor can be reconstructed by measuring the instantaneous current of a bus according to the switching state of an inverter bridge. The general integrated power module integrates a PWM driving protection circuit and a module temperature measuring circuit.
For the star-closing relay, when the input voltage of the control device is disconnected, the automatic door is in a free state when the driving braking force is lost, and if the automatic door is in a high-speed motion state at the moment, severe mechanical collision can be generated to cause damage. In order to slow down the moving speed of the door, the three phase lines of the motor are connected into a point to add extra braking force, namely, braking electromagnetic force is generated in the motor, so as to achieve the purpose of reducing speed and reducing collision force.
The control unit is electrically connected with the power management unit, the power driving unit and the star sealing relay respectively, and the control unit is configured to drive the motor to work through the power driving unit so as to control the automatic door to operate; the control unit is also configured to respond to the abnormal information that the power supply management unit is disconnected from the power supply and/or the control device to control the normally open contact of the star-closing relay to be closed, so that braking electromagnetic force is generated inside the motor, and therefore the automatic door is controlled to decelerate.
The control device also comprises a monitoring unit which is configured to detect the operation data of the control device in real time, and the abnormal information in the control device is obtained by the monitoring unit and the control unit judges whether the sensing signal is abnormal. The operation data of the control device comprises one or more of related data of the motor, voltage of the power management unit and temperature of the power driving unit, and the related data of the motor comprises one or more of magnetic pole position, speed, temperature, ambient temperature, operation voltage and operation current of the motor. Specifically, the control unit is further configured to judge whether the operation data meet a preset range or not, and if not, judge that abnormal information exists in the control device, so as to control the normally open contact of the star sealing relay to be closed.
As shown in fig. 5, the control device further includes a bluetooth module, a communication circuit, and a plurality of I/O interfaces. The Bluetooth module is configured to receive a remote instruction, the Bluetooth module is electrically connected with the control unit, and the control unit is further configured to control according to the remote instruction of the Bluetooth module. The communication circuit is electrically connected with the control unit, and the control unit is also configured to communicate with the outside through the communication circuit. The control device receives external commands and/or sends commands to the outside through the I/O interface.
The invention provides an integrated automatic door control device which can optimize the structural design, save the spatial layout of each part, conveniently and quickly debug various technical indexes of door switch operation, and achieve the satisfactory use effect of users. Specifically, a power driving unit connected with the permanent magnet synchronous motor receives a driving instruction of the control unit to control the rotating speed, current and torque of the permanent magnet synchronous motor, so as to drive the automatic door to operate. The control unit is the core of the automatic door control device and is used for receiving various external instructions, carrying out logic judgment on the instructions, outputting driving instructions to the power driving unit through the operation of a driving algorithm, and monitoring various operation data indexes of the control device in real time, and protecting when the operation data exceed a set value so as to avoid the damage of the control device. The monitoring unit, i.e. the sensing unit, is used for sensing various operation data of the control device, such as the position and speed of the motor, the temperature of the power driving unit, the temperature and the ambient temperature of the permanent magnet synchronous motor, the operation current and voltage of the motor, and the voltage of the monitoring power management unit through the magnetic encoder assembly, and transmitting the data to the control unit for algorithm analysis and logic judgment. The permanent magnet synchronous motor is connected with the power driving unit to be used as an actuating mechanism for driving the door switch to operate. The power management unit provides power driving power for the whole control device, also provides electric energy for the control unit, and has an overvoltage and overcurrent protection function.
It should be noted that the control unit is the core of the integrated automatic door controller, and is responsible for the SVPWM algorithm and the drive control of the motor drive, detecting various states of the system (such as overcurrent protection of the motor, protection of module temperature and motor temperature, detection of motor magnetic pole position and speed signal, current and voltage of the motor, etc.), controlling various units of the system (such as PFC control algorithm, power control protection logic, automatic door anti-collision star-sealing control logic, etc.), and performing information interaction with an external interface (not only an IO port interface capable of realizing basic door drive instruction and output state instruction, but also a CAN and 485 interface conforming to the industry standard, thereby facilitating network control).
