The motor and the controller can be packaged in the same shell, and the built-in design of the controller is achieved. The motor may be a dc brushless motor. Correspondingly, the built-in motor controller may be a non-inductive vector dc brushless motor built-in controller.

Further, when the built-in motor controller is a non-inductive vector brushless direct current motor built-in controller, the motor software upgrading tool is correspondingly a non-inductive vector brushless motor driving software upgrading tool.

In addition, when the built-in controller of the direct current brushless motor needs to use an online simulation function in a development stage, the motor software upgrading tool can be directly connected with a VSP pin and an FG pin of the built-in controller of the direct current brushless motor, the two 0-ohm resistors do not need to be welded at the moment, and the motor software upgrading tool can normally use an online debugging function. After the controller is debugged, the two 0-ohm resistors are welded back, and a motor control researcher can optimize and upgrade driving software of the direct current brushless motor through the VSP speed regulating circuit and the FG feedback circuit.

In order to better understand the upgrade compatible circuit for the driver software of the embedded motor controller and the motor device, the following detailed explanation is made with reference to specific embodiments.

As described in the background art, the existing method for upgrading driving software of a dc brushless motor generally uses two interfaces for upgrading and debugging driving software of a researcher through two reserved driving software interfaces of a main control chip. The drive software upgrading mode is only used in the development stage of the drive software of the direct current brushless motor controller, and once the drive controller is installed in the motor, the drive software of the motor cannot be upgraded. If the motor is abnormal or the motor steering needs to be changed, a researcher cannot directly upgrade the driving software of the motor, and only can upgrade the driving software of the built-in motor controller by detaching the end cover of the motor. The motor researcher needs to match the load to debug the motor, and once the motor driving software is upgraded by disassembling and assembling the motor, the performance of the motor can not be ensured, and the load is disassembled and assembled for many times, so that the working efficiency of the researcher and the rapidity of solving the problem are greatly reduced. Therefore, a method for upgrading the driving software of the motor without assembling and disassembling the motor is needed.

The conventional direct current brushless motor driving software upgrading circuit is characterized in that a driving software upgrading interface is directly led out from a control chip to upgrade the motor controller software, then two pins are additionally arranged on a VSP voltage speed regulating circuit and an FG rotating speed feedback circuit to realize the functions of the driving software upgrading circuit, the conventional design occupies pin resources of the chip, and the number of pins required by the chip is large. According to the motor five-wire power line interface, two wires in the motor five-wire power line, the Vsp wire and the FG wire serve as interfaces compatible with driver software upgrading, and the Vsp wire and the FG wire are connected with driver software upgrading pins of a main control chip (namely a motor built-in controller) through 0 ohm resistors respectively. The circuit design can lead the built-in controller of the motor to be installed in the motor and then can upgrade the driving software of the controller. Two 0 ohm resistors are removed, and a driving software upgrading function and an online simulation function can be normally used. After the performance of the motor is optimized and debugged, the two 0-ohm resistors are welded back, the VSP speed regulating circuit and the FG feedback circuit can be normally used by the motor, and when the motor needs to be optimized and upgraded, the driving software upgrading circuit can be compatibly used. The compatible drive software upgrading circuit can debug the motor without disassembling the motor, analyze and upgrade the drive software according to the abnormal condition of the load, can not influence the performance of the motor, is convenient for field debugging and improves the debugging efficiency.

As shown in fig. 1, the two pins of the main control chip of the motor controller for upgrading the driving software of the dc brushless motor controller are respectively connected to the VSP speed adjusting circuit and the FG feedback circuit through two 0-ohm resistors, and the built-in controller of the motor still has five external connection lines: VDC, GND, VCC, VSP and FG, as shown in FIG. 2. When the direct current brushless motor controller needs to use an online simulation function in a development stage, the two 0-ohm resistors do not need to be welded, and the motor control board can normally use an online debugging function. After the controller is debugged, the two 0-ohm resistors on the controller are welded back, and a motor control researcher can optimize and upgrade the driving software of the direct current brushless motor through the VSP speed regulating circuit and the FG feedback circuit, as shown in FIG. 3, without repeatedly disassembling and assembling the motor for debugging and upgrading.

Fig. 4 is a schematic flow chart of online simulation and upgrade of driving software of the motor built-in controller, which can detect whether a 0 ohm resistor is welded through the motor driving controller, and if the 0 ohm resistor is not welded, the online simulation function of the driving software of the motor built-in controller can be directly performed through a program download interface, or the driving software upgrade function of the driving software of the motor built-in controller can be directly performed through the program download interface; after 0 ohm resistance welding, performing a driving software upgrading function on driving software of a built-in motor controller through VSP and FG interfaces of the motor; therefore, the updating and upgrading of the driving software of the built-in controller of the motor are completed, and the motor is optimized and debugged.

Specifically, the drive software upgrading circuit compatible with VSP speed regulation and FG feedback of the sensorless vector direct current brushless motor is used for upgrading drive software of a built-in controller of the motor through a VSP speed regulation circuit and an FG feedback circuit led out by a researcher, and two pins of a main control chip for upgrading the drive software are respectively connected to the VSP speed regulation circuit and the FG feedback circuit through two 0-ohm resistors. When the controller is matched with a motor in a development stage, the two 0-ohm resistors can not be welded, the drive software upgrading function and the online simulation debugging function of the main control chip are normally used, after the no-load performance of the motor is optimized through online matching debugging, the two 0-ohm resistors are welded, then the controller is installed in the motor, and the VSP speed regulating circuit and the FG feedback circuit led out from the motor are used for updating and optimizing debugging the drive software of the built-in controller of the motor.

Wherein the function of the two 0 ohm resistors is: when the two 0-ohm resistors are not welded, a researcher can normally use the drive software upgrading function and the online simulation debugging function of the main control chip; when the two 0 ohm resistors are welded, a researcher can update and upgrade the driving software of the built-in controller of the motor through the VSP speed regulating circuit and the FG feedback circuit led out from the motor. In the research and development stage before leaving the factory, the motor is not assembled, and 0 ohm resistor is not welded at the moment, and software upgrading and online simulation debugging are directly carried out through five wires of the controller; after two 0 ohm resistors are welded and motor assembly is completed, the driving software of a built-in controller of the motor is updated and upgraded by utilizing the extracted VSP speed regulating circuit and the FG feedback circuit.

It should be noted that, in the prior art, the VSP pin and the FG pin are separately connected to the chip, two data pins required for programming are also configured additionally, and the software upgrading circuit multiplexes the two data pins required for programming into the VSP and FG, where the external VSP and FG need to be connected to the chip. The two 0 ohm resistors are connected, are similar to jumper caps, are welded when being connected with the outside and are not required to be disconnected, and the control board does not have much space for arranging the jumper caps, so that the space is saved by selectively utilizing the two 0 ohm resistors. When the driving software of the controller needs to be updated and optimized, the software upgrading tool is connected with the VSP speed regulating circuit and the FG feedback circuit, so that the driving software of the motor built-in controller is updated and optimized and debugged through the VSP speed regulating circuit and the FG feedback circuit, and the motor can update and debug the driving software without disassembling a rear end cover.

According to the drive software upgrading circuit compatible with VSP speed regulation and FG feedback of the non-inductive vector brushless DC motor, two 0-ohm resistors are removed, the drive software upgrading function and the online simulation function can be normally used, after the performance of the motor is optimized and debugged, the two 0-ohm resistors are welded back, the VSP speed regulation circuit and the FG feedback circuit can be normally used by the motor, and when the motor needs to be optimized and upgraded, the drive software upgrading circuit can be compatibly used. Through the design, the upgrading circuit of the direct current brushless motor driving software in the development stage can be reserved, the online simulation circuit of the direct current brushless motor driving software in the development stage can be reserved, the motor can be upgraded under the condition that the motor is not disassembled, two pin resources of a motor main control chip can be saved, and manpower and material resources for processing when the motor is abnormal can be saved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
