Through the technical means adopted by the power control system of the present invention, the Wi-Fi module can receive the control command of the operating device through the network, so that the power control system of the present invention can be remotely controlled by the user. Moreover, by wireless transmission, the wiring and wiring personnel can be reduced between the controller and the operating device without transmitting signals via the signal line, thereby reducing the cost of installation and maintenance.

Hereinafter, embodiments of the present invention will be described based on Figs. 1 to 2 . This description is not intended to limit the embodiments of the invention, but is an embodiment of the invention.

As shown in FIG. 1, a power control system 100 according to an embodiment of the present invention includes: a motor 1; a driver 2 electrically connected to the motor 1 to drive the motor 1, and the driver 2 is configured to sense the motor 1 The operation parameter P, and the transmission operation parameter P; and a controller 3, the signal is connected to the driver 2, the controller 3 includes a Wi-Fi module 31, and the Wi-Fi module 31 is configured to receive the transmission via the wireless network. A control command C, the controller 3 transmits a corresponding control signal S to the driver 2 according to the control command C and the operating parameter P from the driver.

Thereby, the Wi-Fi module 31 can receive the control command C through the network, so that the power control system 100 of the present invention can be remotely controlled without affecting the range of the user's operation and control due to the length of the signal line, and repairing The personnel need not be present to adjust the parameters of the motor 1, and the transmission of the control command C is not affected by the electromagnetic interference caused by the large current. Moreover, by wireless transmission, there is no need to transmit wiring and wiring personnel between the controller and the operating device via the signal line, thereby reducing the cost of installation and maintenance.

In detail, the position of the axis of the motor 1 is controlled by current. The driver 2 drives the motor 1 according to the control signal S of the controller 3, controls the rotation speed of the motor 1, and compensates the rotation speed.

In the present embodiment, the motor 1 is a synchronous motor. By the characteristics of the synchronous motor, the driver 2 drives the current of the motor 1 to control the torque of the motor 1, and drives the voltage frequency of the motor 1 to control the rotational speed of the motor 1. Therefore, it is possible to determine whether the motor 1 is damaged by sensing whether the current and voltage of the motor 1 are abnormal. The power control system 100 of the present invention does not need to provide other sensors for abnormality detection, and can reduce the number of sensors and the sensor respectively. Wiring required to connect to the motor and controller.

After receiving the current value and the voltage value fed back by the motor 1, the controller 3 calculates the position and the rotational speed of the motor 1, and obtains the rotational speed compensation information and the position compensation information for the control command C by the position and the rotational speed ratio of the motor 1. Further, a control signal S including speed compensation information and position compensation information is provided to the driver 2.

In addition to receiving the control command, the Wi-Fi module 31 can also transmit the operating parameter P of the motor 1 through the wireless network, so that the power control system 100 of the present invention can be remotely monitored, and the maintenance personnel need not to monitor the motor 1 Operating parameter P.

As shown in FIG. 2, the power control system 100a according to the second embodiment of the present invention has a structure substantially the same as that of the power control system 100 of the first embodiment, except that the router 4 and the storage device 5 are further included.

The router 4 is connected to the Wi-Fi module 31 via Wi-Fi to transmit and amplify the control command C. The storage device 5 is connected to the controller 3 by wired or wireless signals to receive and store the operational parameters P of the motor 1. The storage device 5 can be a server local to the company or a third-party cloud space. In the present embodiment, the storage device 5 is connected to the Wi-Fi module 31 via a wireless network. The storage device 5 is a server local to the company, so as to prevent the device usage from being illegally acquired by the hacker, and has high security.

The operation device O can be a fixed machine or a mobile device. In the present embodiment, the operating device O is a mobile device, and a control command C is issued through the APP, so that the motor 1 can be operated anywhere to further improve the convenience of operation.
