[0030] See also Figure 2 , Figure 2 FIG. 1 is a flowchart of a method for quickly resetting an electric actuator after power failure, which is shown in an exemplary embodiment of the present application. Figure 2 As shown, in an exemplary embodiment, the method for quickly resetting the electric actuator after power failure includes at least steps S210 to S240, which are described in detail as follows:

[0031] Step S210, detecting the external input power supply and the internal emergency power supply of the electric actuator to obtain the external voltage and the internal voltage.

[0032] In one embodiment of the present application, a power detection circuit is designed and integrated through a high-sensitivity, low-temperature-drift precision resistor and a power detection chip, including real-time monitoring of the power supply voltage (external voltage), capacitor charging voltage, and capacitor voltage (internal voltage), to help the system to monitor the power supply, charging, and discharging ends through a complete voltage monitoring system.

[0033] Step S220: If the external voltage is less than the preset power-off threshold, the electric actuator is switched from the external power supply mode to the internal power supply mode, and a reset procedure of the electric actuator is triggered.

[0034] In one embodiment of the present application, if the external voltage is less than a preset power-off threshold, the electric actuator is converted from an external power supply mode to an internal power supply mode, and the reset procedure of the electric actuator is triggered, including: adjusting the operating speed of the electric actuator from a normal operating speed to a first emergency speed, and triggering the reset procedure of the electric actuator to quickly reset the electric actuator to a preset position.

[0035] Step S230: If the external voltage is greater than or equal to the preset power-off threshold and the internal voltage is less than the preset charging threshold, the charging circuit of the internal emergency power supply is turned on to charge the internal emergency power supply.

[0036] In one embodiment of the present application, if the charging circuit of the internal emergency power supply is turned on to charge the internal emergency power supply, the method includes: if the external voltage is greater than or equal to a preset power-off threshold and the external voltage is outside a preset charging voltage range, the boost chip in the charging circuit is turned off to step down and charge the internal emergency power supply; if the external voltage is greater than or equal to a preset power-off threshold and the external voltage is within a preset charging voltage range, the boost chip in the charging circuit is turned on to step up and charge the internal emergency power supply.

[0037] Step S240: If the external voltage is greater than or equal to the preset power-off threshold, and the internal voltage is greater than or equal to the preset charging threshold, the charging circuit of the internal emergency power supply is turned off to stop charging the internal emergency power supply.

[0038] In one embodiment of the present application, the method for quickly resetting the electric actuator after power failure also includes: if the external voltage is greater than or equal to a preset power failure threshold and a reset control instruction is received, the operating speed of the electric actuator is adjusted from a normal operating speed to a second emergency speed, and the reset program of the electric actuator is triggered to quickly reset the electric actuator to a preset position.

[0039] The embodiment of the present application provides an electric actuator that quickly resets after power failure, and the electric actuator that quickly resets after power failure includes an internal emergency power supply, a power detection module, a power charging and discharging module, and an intelligent control module;

[0040] The internal emergency power supply includes multiple supercapacitors, which are used to provide working power for the electric actuator when the electric actuator is in the internal power supply mode; the power supply detection module is used to detect the external voltage of the external input power supply and the internal voltage of the internal emergency power supply; the power supply charging and discharging module includes a boost chip or a buck chip, which is used to boost or buck charge the internal emergency power supply; the intelligent control module is used to control the electric actuator to switch from the external power supply mode to the internal power supply mode if the external voltage is less than a preset power-off threshold, if the external voltage is greater than or equal to the preset power-off threshold, and the internal voltage is less than the preset charging threshold, then control the power supply charging and discharging module to charge the internal emergency power supply, if the external voltage is greater than or equal to the preset power-off threshold, and the internal voltage is greater than or equal to the preset charging threshold, then control the power supply charging and discharging module to stop charging the internal emergency power supply.

[0041] In one embodiment of the present application, the intelligent control module is also used to control the power supply charge and discharge module to turn on the boost chip to step down and charge the internal emergency power supply if the external voltage is greater than or equal to a preset power-off threshold and the external voltage is outside a preset charging voltage range; if the external voltage is greater than or equal to a preset power-off threshold and the external voltage is within a preset charging voltage range, the power supply charge and discharge module is controlled to turn on the boost chip to step up and charge the internal emergency power supply.

[0042] In one embodiment of the present application, the electric actuator that quickly resets after power failure also includes a safety protection module; the safety protection module includes an overload protection circuit. If it is detected that the current of the overload protection circuit exceeds a preset safety current threshold, or the voltage of the overload protection circuit exceeds a preset safety voltage threshold, the overload protection circuit is disconnected to provide safety protection for the electric actuator.

[0043] In one embodiment of the present application, the power supply detection module can detect the voltage status of the external input power supply in real time and quickly capture the voltage changes of the external power supply. A voltage lower limit status detection terminal is designed in hardware, and an emergency reset voltage upper limit can also be set in software. If it is detected that the external voltage of the external input power supply is lower than the preset power-off threshold, it means that an emergency situation such as power interruption or signal interruption has occurred at this moment. The power supply detection module immediately sends an emergency signal to the intelligent control module, so that the intelligent control module converts the external power supply mode to the internal power supply mode through the built-in hardware circuit mechanism, that is, switches the working power from the external input power supply to the internal emergency power supply.

[0044] In one embodiment of the present application, the power detection module selects high-sensitivity, low temperature drift precision resistors and power detection chips, designs and integrates the power detection circuit, including real-time monitoring of the power supply voltage, capacitor charging voltage and capacitor voltage, to help the system monitor the actual voltage of each link in real time through a complete voltage monitoring system at the power supply end, charging end and discharging end to ensure the normal operation of the system.

[0045] In one embodiment of the present application, when the external input power is restored, the power detection module will send a signal to the intelligent control module. After receiving the signal, the intelligent control module will perform a self-check operation to check whether the components of the system are in a normal state. After the self-check passes, the intelligent control module will receive external instructions again according to actual needs and control the electric actuator to perform corresponding actions.

[0046] In one embodiment of the present application, the internal emergency power supply uses a supercapacitor as the internal emergency power supply. When the external input power supply is interrupted, the internal emergency power supply quickly takes over the power supply task to ensure that the control system and the motor continue to work for a period of time. When the capacitance capacity of the internal emergency power supply meets the external power supply interruption, the on-site switch operation can be performed three times, and the micro-power consumption mode is triggered at the same time to reduce the power consumption to the micro-ampere level, extend the standby time, and wait for manual emergency operation. The capacitors of the internal emergency power supply are combined in series and parallel according to the actual power demand. The capacitor module is equipped with an overcharge / equalizing protection module to prevent overvoltage charging, and ensure that the voltage of each single capacitor is consistent, extending the cycle life. The supercapacitor used in the internal emergency power supply has high safety and low temperature characteristics, and can work normally between -40°C and 70°C. Compared with the capacity attenuation of commonly used lithium batteries in low temperature environments, the application of supercapacitors in extreme climatic conditions is more reliable. In addition, the cycle life of the supercapacitor can reach 500,000 times, which is an ideal emergency power supply.

[0047] In one embodiment of the present application, the internal emergency power supply is provided in the form of a series-parallel combination of a single supercapacitor, which can be flexibly configured according to different capacity requirements. In terms of circuit design, a high-precision voltage monitoring module is designed for each supercapacitor, which can prevent overcharging and equalize the voltage of the capacitor, balance the charging voltage of each capacitor, and improve the service life of the capacitor. When the capacitor voltage is close to the safe full charge voltage, the capacitor voltage monitoring module adjusts and shuts off the capacitor charging circuit, reduces the charging current, and effectively ensures the voltage balance between the capacitors to prevent overcharging. In order to ensure the safe operation of the internal emergency power supply, a temperature sensor is also designed on the module, which can collect the temperature around the emergency power supply in real time to ensure normal operation.

[0048] In one embodiment of the present application, the power charging and discharging module adopts a wide range input voltage design, which can receive a variety of external input voltages from low voltage (such as 12V) to high voltage (such as 48V). The power detection module monitors the value of the external input voltage in real time. By comparing the external voltage with the preset power-off threshold, it can intelligently identify the current power system level, and integrate an adjustable power charging and discharging module to efficiently charge the capacitor. During the charging process, the charging voltage and capacitor voltage are monitored in real time. Based on these real-time data, the charging voltage and charging time are intelligently adjusted. When the capacitor voltage is detected to reach the set threshold, the capacitor charging circuit can be turned off.

[0049] In one embodiment of the present application, the power supply charge and discharge module is implemented with a boost DC-DC chip with a maximum current of 5A, and the voltage can reach up to 60V. The charging voltage is adjusted by adjusting the feedback resistance ratio. If the external voltage is outside the preset charging voltage range, this situation is a circuit abnormality, and the voltage can be stepped down for charging without damaging the system. If the external voltage is lower than the power supply charge and discharge module, multiple voltage monitoring points are designed. During the charging process, the charging voltage and capacitor voltage are monitored in real time. Based on these real-time data, the charging voltage is intelligently adjusted to ensure that the capacitor voltage is fully charged.

[0050] In one embodiment of the present application, the intelligent control module includes multiple reset mode options, including but not limited to automatically driving the device to a fully open state, a fully closed state, maintaining its current position, or accurately moving it to a preset position. In addition, the user is allowed to flexibly configure multiple emergency reset trigger conditions according to the specific needs of the actual application scenario, including automatic reset when the external input power is interrupted, emergency processing when the signal transmission is interrupted, and response to emergency control input triggers.

[0051] In one embodiment of the present application, the reset procedure of the electric actuator, so that the position of the electric actuator resetting to a preset position can be adjusted according to the change of the reset mode, including but not limited to the fully open position, the fully closed position or a preset position.

[0052] In one embodiment of the present application, according to the actual needs of the industrial site, the intelligent control module also includes a function of adjustable power-off delay reset time to adapt to the differences in power-off sensitivity of different equipment and processes, ensuring that signals can be transmitted quickly in the event of a power outage, thereby improving the emergency reset speed.

[0053] In one embodiment of the present application, the electric actuator also has a brushless DC motor with higher speed and torque, which adjusts the operating speed of the electric actuator by outputting different control voltages through PWM, and sets the normal operating speed, the first emergency speed and the second emergency speed, to ensure that when the actuator receives an emergency signal, it can quickly adjust the PWM signal output to the set emergency speed to achieve rapid reset.

[0054] Figure 3 is a schematic diagram of a fast reset process flow diagram of an exemplary embodiment of the present application; now refer to the accompanying drawings Figure 3 , the method for implementing fast reset will be described in more detail in conjunction with the flow chart.

[0055] After power-on, the intelligent control module will obtain the external voltage of the external input power supply in real time, and compare the external voltage with the preset power-off threshold to identify the current power system level, and then prepare for emergency power charging by adjusting the feedback resistance ratio of the charging circuit. If the current external voltage is higher than the set power-off threshold, and the capacitor voltage is lower than the set safe full charge threshold (preset charging threshold), the capacitor needs to be charged; otherwise, the capacitor charging circuit is turned off. Before charging, the charging voltage needs to be determined. If the external input voltage is higher or lower than the reasonable range of the charging voltage design (preset charging range), the boost chip is turned off for step-down charging; if the charging voltage is normal, the boost chip is turned on for step-up charging. If it is detected that the current external input power supply voltage is lower than the set power-off threshold, and the power-off delay reset time is valid, the emergency reset trigger condition is determined to be valid, and the reset program will be automatically triggered. According to the preset parameters and logic, the control module sends a full-speed 100% (first emergency speed) operation instruction to the motor to drive the motor to complete the reset operation at the fastest speed. If the external input power supply voltage is normal and valid, and other valid control instructions are received, the module will control the motor to run to the specified position at 50% speed (normal operating speed). If the external input power supply voltage is normal and valid, and a reset control instruction is received, the module controls the motor to complete the reset operation at 60% speed (second emergency speed). The setting of the motor running speed in this embodiment depends on the design of the actuator, and the present invention is not necessarily intended to be limited to the specific setting value in this regard.

[0056] In one embodiment of the present application, the electric actuator that quickly resets after power failure also includes a safety protection module. While improving the emergency speed, the design of safety protection includes but is not limited to: designing an overload protection mechanism to prevent damage caused by overload operation of the motor; designing short-circuit protection to cut off abnormal current in time to prevent the risk of circuit damage; and designing overvoltage protection to ensure that when the voltage rises abnormally, the equipment can operate safely and stably to avoid potential safety accidents. An anti-reverse connection circuit, an overvoltage protection circuit, and a short-circuit fuse circuit are designed at the power input end. In order to prevent the motor from overloading, an overload protection is designed by collecting the motor current. The overload protection threshold of the motor current can be configured through the menu to meet the use of different load occasions. While improving the emergency speed, the equipment can operate safely and stably to avoid potential safety accidents.

[0057] In one embodiment of the present application, the electric actuator that quickly resets after power failure adopts a low-power 32-bit ARM chip. In low-power mode, most of the functional circuits are turned off, and the necessary working modules are retained to extend the standby time as much as possible. Under normal working conditions, the capacitor power of the internal emergency power supply can meet the actuator's three full-stroke opening or closing operations. When the capacitor of the internal emergency power supply is powered, in order to reduce the discharge burden of the capacitor, non-essential functional circuits in the current standby state are selectively turned off, such as: the backlight and display functions of the display, 4-20mA input sampling, valve position feedback output, etc., to reduce unnecessary power consumption. At the same time, key working modules are retained to maintain the basic operation of the equipment to ensure that the equipment is still responsive during the loss of external power. This method can effectively extend the duration of capacitor power supply and ensure that the equipment can meet the immediate needs of users.
