It is worth mentioning that, in terms of the development process of the motor control program, after the motor establishes network communication with the external host equipment, the microprocessor receives the communication instruction sent by the external host equipment through the network communication module, and selects a matched communication address from a plurality of communication addresses according to the address code contained in the communication instruction to realize the network communication with the external host equipment, at the moment, only one set of program (namely, the address selection program) for judging the address code contained in the communication instruction sent by the external host equipment is needed to be arranged in the microprocessor of the motor, only one set of address selection program can enable the motor to be suitable for a plurality of different application scenes, a plurality of sets of corresponding address selection programs do not need to be developed aiming at the plurality of different application scenes, the development period of the whole control program of the motor can be effectively shortened, and the development cost of the whole control program of the motor is reduced, the reliability of the whole control program of the motor can be improved better, communication modes under different application scenes are integrated in the same motor control program, and maintenance and borrowing of subsequent software are facilitated greatly.

As a preferable scheme, the address code of the first communication address is 0x00, and the address code of the third communication address is 0 xFF.
It is worth mentioning that the address code of the first communication address and the address code of the third communication address are set based on the Modbus RTU communication protocol in the scheme, and when the Modbus RTU communication protocol is actually used, the address code of the first communication address and the address code of the third communication address can be set according to the actual situation; based on the Modbus RTU communication protocol, the communication command sent by the external host device generally includes an address code, a functional command code and a check code.
Specifically, the first communication mode is that the external host device only performs network communication with one motor serving as the slave device, the motor serving as the slave device returns a communication instruction received from the external host device to establish network communication between the external host device and the one motor serving as the slave device, and the external host device only controls the one motor serving as the slave device to operate.
For example, a user only needs an external host device to establish a network communication with a motor, that is, the external host device controls the operation of the motor (single-to-single mode), in this application scenario, selects a first communication address of the motor to establish the network communication between the external host device and the motor, when in use, the external host device and the motor are well connected, after the power is turned on, if the operation state of the motor needs to be changed, the external host device only needs to send a communication command "0 x 000 x 060 x 000 x0B 0x 010 x 900 x f 80 x 25" to the motor to change the current operation state of the motor, after receiving the command, the motor responds and returns a communication command "0 x 000 x 060 x 000 x0B 0x 900 x 80 x 25" to the external host device, through a mutual communication process, the external host device can know that the command has been received by the motor and can correctly respond, so as to realize the control of the external host device over a single motor, in this embodiment, "0 x 00" is the address code of the first communication address, "0 x 060 x 000 x 0B" is the function command code, here denoted as the tachometer command, "0 x 010 x 90" is the assignment code of the function command code, here denoted as the tachometer command 400rpm, and "0 xF 80 x 25" is the CRC check code.
Specifically, the second communication mode is that an external host device and a plurality of motors serving as slave devices are in networking communication, each motor serving as a slave device has a unique second communication address, after a motor serving as a slave device with the unique second communication address receives a communication instruction sent by the external host device, the motor serving as a slave device with the unique second communication address returns the communication instruction to the external host device to establish networking communication with the external host device, and the external host device can control the plurality of motors serving as slave devices to work.
For example, if a user needs an external host device to establish networking communication with multiple motors, the external host device controls the multiple motors to work, the external host device sends multiple communication commands, each communication command is sent out for different motors (single-pair multi-mode), in this application scenario, a second communication address of each motor is selected to establish networking communication between the external host device and the motors, when in use, the external host device is connected with the multiple motors, after the external host device is powered on to operate, if the operation state of a certain motor needs to be changed, the communication can be realized only by knowing an address code of the second communication address of the motor, assuming that the second address of the motor is the external address code of "0 x 81", at this time, the host device only needs to send a communication command of "0 x 810 x 060 x 000 x0B 0x 010 x 900 x e 60 x 34" to the motor to change the current operation state of the motor, and when the motor receives the communication command, the motor responds, and returns a communication command "0 x 810 x 060 x 000 x0B 0x 010 x 900 xE 60 x 34" to the external host device, through a process of mutual communication, the external host device can know that the motor has received the communication command and can make a correct response, for the control of other motors, the communication instruction is sent to the corresponding motor by the method, in the communication mode, the external host device only controls the motor with the corresponding communication address every time the command is sent, and through the sending of the appointed communication address, can effectively avoid the confusion of communication command transmission, ensure that the corresponding motor can correctly execute the relevant command, in this embodiment, "0 x 81" is the address code of the first communication address, "0 x 060 x 000 x 0B" is the function instruction code, here denoted as the tachometer instruction, "0 x 010 x 90" is the assignment code of the function instruction code, here denoted as the tachometer instruction 400rpm, "0 xE 60 x 34" is the CRC check code.
Specifically, the third communication mode is that an external host device and a plurality of motors serving as slave devices are in networking communication, the motors serving as the slave devices all have the same third communication address, the external host device sends a communication instruction by using the third communication address, the motors serving as the slave devices do not return the communication instruction received from the external host device to the external host device, so that the external host device and the motors serving as the slave devices are in networking communication at the same time, and the external host device controls the motors serving as the slave devices to work at the same time.
For example, if a user needs an external host device to establish networking communication with multiple motors, and the external host device can simultaneously control the multiple motors to work, that is, the external host device only needs to send a communication command, and all the motors serving as slaves can receive and execute the communication command (single-pair multi-mode, and the external host device can simultaneously control the multiple motors to work), in this application scenario, the third communication address of each motor is selected to establish networking communication between the external host device and the motors, when in use, the external host device is connected with the multiple motors, after the external host device is powered on to operate, if the operation states of all the motors need to be changed, the external host device only needs to send a communication command of "0 xff 0x 060 x 000 x0B 0x 010 x 900 x ec 0x 2A" to change the current operation states of all the motors, and when all the motors receive the communication command, the external host device responds, in this communication mode, since the external host device simultaneously controls the plurality of motors as the slave devices to operate, in order to avoid the disorder of the entire communication system, at this time, all the motors do not return a communication command "0 xff 0x 060 x 000 x0B 0x 010 x 900 xEC 0x 2A" to the external host device, since the external host device only needs to send a communication command once and all the motors do not return a communication command, so that all the motors do not need to respond in turn, in this communication mode, the response between the motors and the external host device is faster, so as to improve the communication efficiency between the motors and the external host device, in this embodiment, "0 xff" is an address code of the third communication address, "0 x 060 x 000 x 0B" is a functional command code, which is denoted as a rotation speed command, "0 x 010 x 90" is an assignment code of the functional command code, which is denoted as a rotation speed command 400rpm, "0 xEC 0x 2A" is a CRC check code.
The scheme gives the motor three different communication addresses, wherein a first communication address and a third communication address are addresses set by direct program solidification, a second communication address is set according to actual use conditions, the second communication address is one of address ranges from the first communication address to the third communication address, the motor and external host equipment can select corresponding communication addresses according to different communication modes to realize networking communication of the motor and the external host equipment in different communication modes by setting a plurality of different communication addresses, when the communication is used, the corresponding communication address in the communication mode is selected according to a communication mode to be used, the specific method is that an address code contained in a communication instruction sent by the external host equipment is matched with the communication address, and as the motor serving as the slave equipment is provided with a plurality of different communication addresses, the motor can adapt to various different application scenes, thereby improving the compatibility of the motor, avoiding management confusion, reducing the management cost, increasing the functions of the motor, being suitable for different application scenes of a user terminal, enlarging the application range of the motor, aiming at the development process of a motor control program, only needing to set a set of program (namely, a site selection program) for judging address codes contained in communication instructions sent by external host equipment in a microprocessor of the motor, only needing to set the site selection program to enable the motor to be suitable for various different application scenes, not needing to develop a plurality of sets of corresponding site selection programs aiming at various different application scenes, effectively shortening the development period of the whole control program of the motor, reducing the development cost of the whole control program of the motor, and better improving the reliability of the whole control program of the motor, and communication modes under different application scenes are integrated in the same motor control program, so that the maintenance and borrowing of subsequent software are greatly facilitated.
It should be further noted that, in this embodiment, the network communication module is an RS485 communication module or an RS232 communication module, and the microprocessor is a single chip microcomputer MCU or a digital signal processor DSP, where in this scheme, the network communication module is an RS485 communication module, and a circuit diagram of the RS485 communication module is shown in fig. 3.
Example two:
in this embodiment, the second communication address is obtained by an external giving signal, and the specific method may be as follows: an erasable storage structure (on-chip Flash) in the microprocessor is utilized, in a 485 communication network, an external host device sends a communication code with an address to each motor, and the motor stores the communication code with the address in the erasable storage structure (on-chip Flash) of the microprocessor after receiving the communication code to realize the distribution of a second communication address so as to determine the second communication address; by the address allocation method, when the motor leaves a factory, the address code of the second communication address does not need to be preset, when the motor is used by a user, the user can complete the allocation of the second communication address according to the actual situation, so that the second communication address of the motor can be randomly changed according to the idea of a user side, and meanwhile, the user side can quickly set the same second communication address after the motor is replaced in the later period, so that the motor and the master controller which are used as the slave equipment can be flexibly configured by designing various assignment modes of the second communication address of the motor which is used as the slave equipment, and the motor which is used as the slave equipment in the later period can allocate the second communication address for use according to the actual situation; in this embodiment, the first communication address and the third communication address are still stored in a ROM (read only memory) of the microprocessor.
