Embodiment 1

[0044] Embodiment 1: as figure 1 As shown, a brushless motor control method is mainly to copy the port in the form of pure digital through pLINK, and map out the virtual port with the same function as the physical control port, so as to realize the separation of the control port from the brushless motor controller body , away from the harsh working environment full of various oils, water, dust, and metal debris, so as to simplify equipment installation, maintenance and interface protection, and reduce costs. Such as image 3 As shown, the specific steps are as follows:

[0045] Step 1: Perform virtual port initialization configuration in the microprocessor. The microprocessor is a local microprocessor and a remote microprocessor, and the virtual port is a local virtual port and a remote virtual port. The local virtual port completes the initial configuration in the local microprocessor, and the remote virtual port completes the initial configuration in the remote microproces...

Embodiment 2

[0059] Embodiment 2: as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that this embodiment restores the control port of the entity at the remote control end for manual control, which is suitable for one-to-one or one-to-two remote control. Its composition is as follows: the microprocessor in the virtual port emulator leads to the control port of the entity, and the input is a pLINK cable or a wireless network module. Since the remote physical port can be far away from the brushless motor controller, it can be placed in a place that does not require high-level protection, and ordinary non-three-proof connectors can be used.

[0060] The virtual port driver running in the microprocessor replaces the physical control port and duplicates the virtual control port in the microprocessor memory. At the same time, the driver program running in the microprocessor establishes the mapping relationship with the virtual port through the controller port cont...

Abstract

The invention relates to a motor control method, in particular to a method for remotely controlling a motor through port replication. The motor control method is characterized in that a control port is replicated in a customized pLINK mode, and is separated from a controller body, control commands are issued remotely and executing data and real-time running data are fed back; and different supported protocols can be replaced or converted by the pLINK layer according to applications of a user, information is coded and decoded, the supported protocols can be changed or increased by upgrading driving software, each protocol is provided with an individual data channel, and communication instantaneity and communication efficiency are guaranteed. Installation, later maintenance and interface protection of a motor controller can be greatly simplified; the installation speed is increased; the number and the types of interfaces are reduced; the purchasing cost is reduced; a network can be controlled in a centralized and distributed mode; networking groups can run synchronously or asynchronously; and information of a plurality of controllers can be shared.

Description

technical field [0001] The invention relates to a motor control method, in particular to a motor control method for realizing remote control by separating a control port from a motor controller body in a pLINK port duplication mode. Background technique [0002] Brushless motors refer to motors without brushes and commutators. At present, the main applications are DC brushless motors and AC synchronous servo motors. Brushless motors with excellent performance are closely integrated with power electronics technology, microelectronics technology, digital technology, control technology and material science, and will become the driving source of various machines and equipment in the future. Brushless motors are not new, but in recent years, with the development of high-power electronic devices MOS, IGBT (Insulated Gate Bipolar Transistor, Insulated Gate Bipolar Transistor), drive control technology and permanent magnet materials, brushless DC motor technology has become With ne...
