[0043] Example 1

[0044] Please see Figure 1 , Figure 1 This is a flowchart illustrating a remote control method for multiple independent motors based on a remote controller, as described in an embodiment of the present invention.

[0045] like Figure 1 As shown, a remote control method for multiple independent motors based on a remote controller includes a remote controller and multiple independent motors, wherein each of the multiple independent motors has a built-in environmental data acquisition device and a gateway node; and the remote controller and the multiple independent motors establish a communication connection based on the gateway node.

[0046] In the specific implementation of this invention, the remote controller communicates with multiple independent motors, generally wirelessly, but wired communication can also be achieved if the distance is short. Each of the multiple independent motors is equipped with an environmental data acquisition device and a gateway node. The environmental data acquisition device is used to collect current environmental data, including current ambient temperature, current ambient humidity, and current ambient air density. The remote controller establishes a communication connection with the multiple independent motors through the gateway node built into each independent motor.

[0047] The method includes:

[0048] S11: When starting control of multiple independent motors connected to the remote controller, the current environmental data information of the multiple independent motors is obtained through the environmental data acquisition device carried by the multiple independent motors themselves;

[0049] In the specific implementation of this invention, the current environmental data information includes current environmental temperature data information, current environmental humidity data information, and current environmental air density data information.

[0050] Specifically, when it is necessary to start and control multiple independent motors connected to it through the remote controller, the environmental data acquisition device installed on the independent motor is first powered on, so that the environmental data acquisition devices carried by the multiple independent motors collect the current environmental data information, and the current environmental data information includes at least the current environmental temperature data information, the current environmental humidity data information, and the current environmental air density data information.

[0051] S12: The multiple independent motors mark the current environmental data information and upload the marked current environmental data information to the remote controller based on the gateway node;

[0052] In a specific implementation of the present invention, the multiple independent motors mark the current environmental data information, including: the multiple independent motors mark the current environmental data information according to the device ID number of each independent motor.

[0053] In the specific implementation of this invention, after each of the multiple independent motors collects and obtains the current environmental data information, the current environmental data information collected by each independent motor can be marked according to the device ID number of each independent motor to form marked current environmental data information. Then, the marked current environmental data information is compressed to form a data compressed package. Then, the data compressed package formed by the marked current environmental data information is uploaded to the remote controller through the gateway node.

[0054] S13: The remote controller performs a startup control simulation based on the current environmental data information of the marked motor, and obtains the startup control simulation results of multiple independent motors;

[0055] In a specific implementation of this invention, the remote controller performs a startup control simulation based on the marked current environmental data information to obtain startup control simulation results for multiple independent motors. This includes: the remote controller performs startup control simulation processing in a digital twin virtual motor model based on the marked current environmental data information to obtain startup control simulation results for multiple independent motors; the digital twin virtual motor model is a model constructed in the remote controller using a digital twin network simulation based on the motor parameters of the multiple independent motors; wherein the motor parameters include motor model parameters, motor input voltage parameters, motor input current parameters, motor output speed range parameters, motor output power range parameters, and environmental parameters affecting the magnitude of motor output power.

[0056] Furthermore, before the remote controller performs the start control simulation based on the marked current environmental data information, the method further includes: the remote controller determining whether each of the plurality of independent motors has marked current environmental data information; if not, obtaining the device ID number of the independent motor corresponding to the unmarked current environmental data information, and using the device ID number to perform matching and positioning on the remote server to obtain the positioning location; matching the nearest independent motor to the positioning location in the remote controller, and using the marked current environmental data information of the nearest independent motor as the marked current environmental data information of the independent motor corresponding to the unmarked current environmental data information.

[0057] Specifically, after receiving the compressed package of tagged current environmental data, the remote controller first parses it and uses the tagged device ID number in the tagged current environmental data to determine whether each of the multiple independent motors to be controlled has collected the tagged current environmental data. However, if there are independent motors that have not collected current environmental data, it is necessary to obtain the device ID number of the independent motor corresponding to the one without tagged current environmental data. Then, the device ID number is used to match and locate the motor on the remote server to obtain the location. Specifically, when setting up these independent motors, the device ID numbers of these independent motors are stored on the remote controller, along with their corresponding locations. The corresponding location can be matched using the device ID number. After matching the nearest independent motor to the location in the remote controller, the tagged current environmental data of the nearest independent motor is used as the tagged current environmental data of the independent motor corresponding to the one without tagged current environmental data.

[0058] Simultaneously, a digital twin virtual motor model is constructed in the remote controller according to the motor parameters of the independent motors. Then, the start-up control simulation is performed in the digital twin virtual motor model on the remote controller based on the marked current environmental data information, thereby obtaining the start-up control simulation results of multiple independent motors. The digital twin virtual motor model is a model constructed in the remote controller using a digital twin network simulation based on the motor parameters of each of the multiple independent motors. The motor parameters include at least the motor model parameters, motor input voltage parameters, motor input current parameters, motor output speed range parameters, motor output power range parameters, and environmental parameters that affect the magnitude of the motor output power.

[0059] S14: The remote controller controls the starting operation of multiple independent motors connected to it based on the simulation results of multiple independent motor starting control.

[0060] In a specific implementation of the present invention, the remote controller controls the starting operation of multiple independent motors connected to it based on the simulation results of multiple independent motor starting control, including: the remote controller generating a starting control command for each independent motor based on the simulation results of multiple independent motor starting control; and sending each independent motor starting control command to the corresponding independent motor to control each independent motor to start operation.

[0061] Specifically, the remote controller generates a start control command for each independent motor based on the simulation results of multiple independent motor start control, and sends the start control command for each independent motor to the corresponding independent motor through the gateway node to control each independent motor to start.

[0062] S15: After the multiple independent motors start working, the remote controller obtains the real-time speed of the multiple independent motors in real time;

[0063] In a specific implementation of the present invention, the remote controller obtains the real-time rotational speed of multiple independent motors in real time, including: the multiple independent motors are equipped with speed sensors, the real-time rotational speed of the multiple independent motors is obtained based on the speed sensors, and the real-time rotational speed is uploaded to the remote controller via a gateway node; the remote controller receives and obtains the real-time rotational speed of the multiple independent motors via the gateway node.

[0064] Specifically, speed sensors are installed inside multiple independent motors. After each independent motor starts, the speed sensor obtains the real-time speed of each independent motor and uploads these real-time speeds to the remote controller through the gateway node. This allows the remote controller to receive and obtain the real-time speeds of the multiple independent motors it controls from these gateway nodes.

[0065] S16: The remote controller performs real-time remote speed adjustment control on the corresponding motor among the plurality of independent motors based on the real-time speed.

[0066] In a specific implementation of this invention, the remote controller performs real-time remote speed adjustment control on the corresponding motors among the plurality of independent motors based on the real-time speed, including: the remote controller obtaining the desired speed of each of the plurality of independent motors; subtracting the desired speed of each independent motor from its real-time speed to obtain the speed difference of each independent motor; inputting the speed difference into an iterative learning model for iterative processing to obtain output iterative control data, and using the iterative control data as a given value for the frequency of the corresponding independent motor; the remote controller performs real-time remote speed adjustment control on the corresponding motors among the plurality of independent motors based on the iterative control data.

[0067] Furthermore, the remote controller performs real-time remote speed adjustment control on the corresponding motor among the plurality of independent motors based on the iterative control data, including: the remote controller inputs the speed difference into a built-in differential control model, and superimposes the differential control quantity input from the differential control model with the iterative control data to form superimposed control data; the remote controller performs real-time remote speed adjustment control on the corresponding motor among the plurality of independent motors based on the superimposed control data.

[0068] Specifically, the remote controller first needs to obtain the desired speed of each of the multiple independent motors. Then, it subtracts the desired speed of each independent motor from its real-time speed to obtain the speed difference. The remote controller has a built-in iterative learning model that can iteratively derive the given value of the frequency of the corresponding independent motor from the speed difference. Therefore, the speed difference is input into the iterative learning model for iterative processing to obtain the output iterative control data, which can then be used as the given value of the frequency of the corresponding independent motor. The remote controller can then use the iterative control data to perform real-time remote speed adjustment control on the corresponding motor among the multiple independent motors.

[0069] When the remote controller performs real-time remote speed adjustment control on the corresponding motors among multiple independent motors through iterative control data, the remote controller needs to input the speed difference into the built-in differential control model, and then superimpose the differential control quantity input from the differential control model with the iterative control data to form superimposed control data; finally, it performs real-time remote speed adjustment control on the corresponding motors among multiple independent motors based on the superimposed control data.

[0070] In this embodiment of the invention, current environmental data of multiple independent motors is collected, and the starting control is simulated using a digital twin virtual motor model at the remote control terminal based on the current environmental data. The starting control of multiple independent motors is then performed based on the simulation results. This allows for precise starting control of each independent motor, effectively extending the motor's lifespan. Furthermore, targeted starting control is implemented based on different situations, reducing the probability of motor failure during startup. Simultaneously, speed adjustment control is performed based on the real-time motor speed, ensuring that the motor speed meets the user's actual needs and reducing the motor's operating power consumption.

However, if there are independent motors that have not collected current environmental data, it is necessary to obtain the device ID number of the independent motor corresponding to the one without tagged current environmental data. Then, the device ID number is used to match and locate the motor on the remote server to obtain the location. Specifically, when setting up these independent motors, the device ID numbers of these independent motors are stored on the remote controller, along with their corresponding locations. The corresponding location can be matched using the device ID number.
