Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings, and all other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention.

The general motor control system of the invention is shown in a schematic diagram in fig. 1, and comprises a controller, an upper computer, one or more controlled motors and a built-in sensor, wherein the controller comprises general control software. The general control software comprises three parts which are respectively: BOOT program, main control program and configuration table. The BOOT program completes the online upgrade of the configuration table or the main control program; the main control program completes the selection of the control architecture and the control parameters and the main control function; the configuration table stores the ID numbers and corresponding parameter information of all controlled objects in the whole system.

The general motor control method flow of the invention is shown in fig. 2, after the controller completes power-on initialization, whether to update the configuration table is determined according to the current instruction received from the upper computer, and the storage of the configuration table is shown in fig. 3. If the controller receives a configuration table updating instruction and updating content, the configuration table is programmed again through the BOOT program, and after the configuration table is updated, the controller is electrified and initialized again and then enters the next step of program; if the controller does not receive the configuration table updating instruction, the next procedure is directly entered. Similarly, the controller judges whether to carry out the main control program upgrading and then enters the next program according to the instruction of the upper computer. After the configuration table of the current state and the main control program are determined, the controller reads an externally input ID number to identify the current specific type of the controlled motor. And the controller selects a corresponding control algorithm framework according to the read ID number and loads corresponding control parameters from the configuration table according to the ID number. The controller further realizes the functions of supplying power to the motor, collecting sensor data, giving an alarm to the upper computer according to the corresponding data limit conditions and the like, thereby completing the control of the controlled motor and the load.

When the control system needs to replace the controlled object and the motor type specification of the control system is within the system control range, the controller is only required to be reconnected with a new controlled motor, the ID number corresponding to the new controlled motor is input into the controller from the outside, and the controller can select the control algorithm structure of the corresponding type according to the ID number after power-on initialization, read the corresponding control parameter in the configuration table and realize the control of the new controlled motor.

When the control system needs to change one or more configuration parameters or main control programs of the controlled motor types within the system control range, such as changing the types or the number of the acquired sensor parameters, changing the rotating speed control strategy of the motor and the like, the update instruction and the update data of the configuration table or the main control program can be directly sent by the upper computer, and the original configuration table and the original main control program data are replaced by the update data. After the software of the controller is upgraded on line, the controller can meet the new control requirement of the system.

When the control system needs to newly add a controlled motor type which is not in the system control range, the upgrading instruction and the updating data of the configuration table or the main control program can be sent by the upper computer, and when the storage capacity of the controller is enough, the newly added configuration table item and the main control program are programmed into the controller software by the controller. After the online upgrade of the controller software is completed, the control requirement of the new type of controlled motor can be met.
