It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The invention provides an address processing method of motor equipment. The device address of the motor is stored in a memory chip of a controller of the motor. The device address may specifically be a physical address of the motor. The method may be implemented by software or by a physical device. When implemented in software, may be implemented in a motor controller. When the motor controller is realized through the entity device, the entity device is connected with the motor controller through the communication interface. For example, via a 485 communication interface, a CAN communication interface, or a SPI communication interface. For example, fig. 2 shows a schematic diagram of a motor and physical device connection according to an embodiment of the invention. As shown in fig. 2, the motor and the device are connected by a communication line. For example, the two are connected in a 485 communication interface mode and communicate; or in the form of a non-polar communication interface in the form of a power carrier in which the communication line is combined with the power line. Optionally, under the condition of connection and communication in a 485 communication interface mode, the communication protocol may adopt a variant structure of ModBus, so that the application scenario can be better adapted.
Fig. 1 is a schematic method diagram of an embodiment of an address processing method for a motor device according to the present invention.
As shown in fig. 1, according to one embodiment of the present invention, the device address processing method includes at least step S110, step S120, and step S130.
And step S110, determining whether to change the current equipment address of the motor.
Specifically, when the method is implemented by a physical device, the device extracts information such as equipment address and the like from the motor. For example, the entity device issues a command to the motor controller to query the device address of the motor, and the motor replies to the current default device address. When the method is realized through software, the information such as the equipment address stored in the storage chip of the controller of the motor can be read. If the default equipment address is replied, the equipment address is proved to be factory setting, and if the equipment address is not changed, the equipment address can be changed.
And step S120, if the equipment address is determined to be changed, a new equipment address is allocated to the motor.
Specifically, whether the equipment address of the motor is changed or not is confirmed, and if the equipment address of the motor is not changed, a motor parameter checking option is entered; if the address is changed, a new equipment address is issued. The assigned new device addresses may be sequentially incremented. For example, the device addresses that can be changed are sequentially determined in a question-and-answer manner according to a preset protocol.
And step S130, storing the new equipment address into a storage chip of a controller of the motor.
In one specific embodiment, the memory space of the memory chip of the controller of the electric machine is divided into memory areas. The storage space utilization is divided into two cases: a case where the utilization rate does not exceed a preset utilization rate (e.g., 50%, i.e., half) and a case where the utilization rate exceeds the preset utilization rate. Under the condition that the utilization rate of the storage space of the storage chip is greater than a preset utilization rate, storing the new equipment address in a sector at the middle position of the storage space; and under the condition that the utilization rate of the storage space of the storage chip is less than or equal to a preset utilization rate, storing the new equipment address in the last sector of the storage space.
The existing motor controller is generally a flash memory with large capacity, after the function of the motor is realized, the occupied space of the code is far smaller than the maximum capacity of the storage space, namely, the utilization rate of the storage space (the ratio of the motor function code to the size of the chip storage space) is low or even half of the storage space is not available, and great waste is caused. In addition, parameters such as motor addresses and the like are generally not larger than the minimum erasing unit in the storage space due to small data quantity, and all the parameters are operated according to the minimum erasing unit, and the data is obtained according to a controller chip manual.
The storage space utilization is divided into two cases: a case where the utilization rate does not exceed a preset utilization rate (e.g., 50%, i.e., half) and a case where the utilization rate exceeds the preset utilization rate. Under the condition that the utilization rate of the storage space of the storage chip of the motor is greater than a preset utilization rate, the equipment identifier of the electric appliance is stored in a sector at the middle position of the storage space; and under the condition that the utilization rate of the storage space of the storage chip of the motor is less than or equal to the preset utilization rate, storing the equipment identification of the electric appliance in the last sector of the storage space.
Fig. 3 shows a motor apparatus address storage flowchart according to an embodiment of the present invention. Specifically, in the case where the storage space utilization rate does not exceed the preset utilization rate (50% in fig. 3), a sector is divided in the storage space near the middle position (total storage space/2 ═ middle position) to store the device information (including at least the device identification, such as the physical address). The original data is stored in the middle position without considering parameters such as physical addresses and the like, and the storage quantity is large. And under the condition that the utilization rate of the storage space exceeds the preset utilization rate, storing the equipment information in the last sector of the storage space.
Optionally, when the existing controller chip stores information, in order to protect data from being deleted by mistake and from being unlocked by default, before storing the information, necessary operations such as unlocking, erasing and the like need to be performed on the sector (the operation information can be determined according to a motor controller chip manual). The stored device information comprises a physical address and can also comprise a back electromotive force parameter of the motor, a resistance inductance coefficient of the motor, the number of punching sheets of the stator and the rotor and the like.
In the case that the memory space utilization rate does not exceed the preset utilization rate, the FLASH memory device can be operated to store the device information after the first address is determined by looking up the first address of the last sector in the FLASH list (the FLASH memory configuration word is cleared by performing the page erase operation on the last page of most controller chips, thereby enabling code protection) which depends on the chip used and can be queried in the specification or specification of the chip. The reason why the last sector is determined is mainly because performing a page erase operation on the last page of most existing controller chips clears the flash configuration word, thereby enabling code protection. Therefore, performing a page erase operation on the last page of the program memory should be avoided.
Optionally, before storing the new device address in the memory chip, determining whether the new device address is used; and if the new equipment address is judged to be used, a new equipment address is allocated to the motor again.
For example, the written device address may be memorized, and if the written device address is written here, a new device address may be reassigned. When the method is executed by the entity device, the entity device has a memory function for the written equipment address, and when the written equipment address is written again, a new equipment address is reallocated and prompting can be performed. The phenomenon that the same equipment address exists in the same network and the out-of-control phenomenon occurs in motor control can be avoided to a certain extent.
When the device adopts the 485 communication interface to be in communication connection with the motor, the problem of cost increase caused by the fact that the motor needs to be provided with dial switches or FLASH outside the chip due to different equipment addresses can be solved based on the communication mode characteristic that only one host computer and a plurality of slave computers are arranged in a 485 bus.
For clearly explaining the technical solution of the present invention, the following describes an execution flow of the device address processing method provided by the present invention with a specific embodiment.
Fig. 4 is a schematic method diagram of a device address processing method according to an embodiment of the present invention. As shown in fig. 4, first, the entity apparatus issues a command for querying an apparatus address of the motor, and the motor replies to a current default apparatus address (the default apparatus address is factory setting, on one hand, it can be confirmed that the apparatus has not been changed, and on the other hand, it can be confirmed that the apparatus can be changed). The device confirms whether the equipment address of the motor is changed, if not, the device can enter a parameter option for checking the motor and check other data; if the address is changed, a new device address is issued, and the motor stores the new device address according to the method in the foregoing embodiment, so as to subsequently send an instruction with the new device address. The above process is based on the ModBus protocol with a variant structure, each communication is replied, and whether the communication is successful can be judged according to replied information. Alternatively, the addresses are assigned, for example, sequentially. And in the case that the issued new device address is used by other motors, another new device address is reallocated for writing. The entity device has a storage and memory function for written equipment addresses, and prompts when the written equipment addresses are written again, so that the phenomenon that the same equipment addresses exist in the same network and the motor control is out of control can be avoided to a certain extent.
The invention also provides an address processing device of the motor equipment. The device address of the motor is stored in a memory chip of a controller of the motor. The device address may specifically be a physical address of the motor. The apparatus may be implemented by software or in a physical device. When implemented in software, may be implemented in a motor controller. When the motor controller is realized through the entity device, the entity device is connected with the motor controller through the communication interface. For example, via a 485 communication interface, a CAN communication interface, or a SPI communication interface. For example, fig. 2 shows a schematic diagram of a motor and physical device connection according to an embodiment of the invention. As shown in fig. 2, the motor and the device are connected by a communication line. For example, the two are connected in a 485 communication interface mode and communicate; or in the form of a non-polar communication interface in the form of a power carrier in which the communication line is combined with the power line. Optionally, under the condition of connection and communication in a 485 communication interface mode, the communication protocol may adopt a variant structure of ModBus, so that the application scenario can be better adapted.

specifically, the determination unit 110 first determines whether or not the device address can be changed, and extracts information such as the device address for the motor. For example, a command for inquiring the device address of the motor is issued to the motor controller, and the motor returns to the current default device address. When implemented by software, the determination unit 110 may read information such as a device address stored in a memory chip of a controller of the motor. If the default equipment address is replied, the equipment address is proved to be factory setting, and if the equipment address is not changed, the equipment address can be changed.

Specifically, whether the equipment address of the motor is changed or not is confirmed, and if the equipment address of the motor is not changed, a motor parameter checking option is entered; if the address is changed, a new equipment address is issued. The assigned new device addresses may be sequentially incremented. For example, the device addresses that can be changed are sequentially determined in a question-and-answer manner according to a preset protocol.
