Description

[Technical Field]

[0001] The present invention relates to an inverter setup method and an inverter setup system. [Background technology]

[0002] Nameplates are sometimes attached to various types of machinery, on which the machine's identification information (for example, product name, manufacturer, model, serial number, and year of manufacture) is clearly written by etching, printing, pressing, etc. Nameplates are made of metal, plastic, or paper, for example, and the necessary information is displayed in a way that will not easily fade.

[0003] Patent Document 1 discloses a system including a machine with a nameplate attached, an image capture device (e.g., a smartphone) equipped with a camera, and a diagnostic device that changes its own settings for the machine based on an image of the nameplate captured by the image capture device (sometimes referred to as a "nameplate image"). In this system, first, the nameplate image of the machine captured by the image capture device is sent to the diagnostic device. Next, the diagnostic device that receives the nameplate image uses optical character recognition (OCR) to extract the machine's identification information from the nameplate image as text data, and compares the text data with a database (repository) related to the machine to search for setting data (control parameters) associated with the machine. The diagnostic device then configures itself for the machine based on the searched setting data. Furthermore, based on the searched setting data, the diagnostic device can diagnose the machine or automatically adjust (set up) the machine's settings. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-178765 Summary of the Invention [Problem to be solved by the invention]

[0005] In the system of Patent Document 1, setup of the machine whose nameplate is the subject of an image capture can be performed using a diagnostic device. Therefore, in a motor drive system including a motor, an inverter that controls the motor, and a camera-equipped device (e.g., a smartphone) capable of setting up the inverter, the technology of Patent Document 1 can be used to set up the inverter using the device. However, in this case, the smartphone functions as both the image capture device and the diagnostic device of Patent Document 1. In this case, the inverter setting data is searched for based on the inverter's identification information obtained from the image of the inverter's nameplate captured by the smartphone. However, without the identification information of the motor controlled by the inverter, the inverter may not be properly set up. Therefore, it is conceivable to search for the inverter setting data based on the identification information of both the inverter and the motor by also photographing the motor's nameplate with a smartphone. However, depending on the inverter, information not listed on the nameplate may be required, which may still prevent proper setup.

[0006] Specifically, this type of motor attribute information not listed on the nameplate includes the maximum frequency. The maximum frequency is set for both the motor and the inverter, and the lower of the two maximum frequencies becomes the maximum frequency for that motor-inverter combination. Generally, the nameplate lists only the rotation speed assumed to be the power supply frequency, not the maximum frequency. Therefore, if a user wants to use the motor at a frequency higher than the power supply frequency, the maximum frequency cannot be read from the nameplate image, and there is a risk that it will be impossible to use the motor at speeds higher than the power supply frequency. In other words, there may be inverter control parameters that can be limited by the motor-inverter combination, and these control parameters can be determined from information not listed on the nameplate.

[0007] An object of the present invention is to provide an inverter setup method that can easily set inverter control parameters that may be limited by the combination of a motor and an inverter. [Means for solving the problem]

[0008] The present application includes multiple means for solving the above problem, and one example thereof includes extracting first identification information, which is identification information of a motor, from a first image obtained by photographing the motor's nameplate or two-dimensional code, extracting second identification information, which is identification information of an inverter that controls the rotation speed of the motor, from a second image obtained by photographing the nameplate or two-dimensional code of an inverter that controls the rotation speed of the motor, extracting from the database a control parameter corresponding to each combination of the motor's identification information and the inverter's identification information using the first identification information and the second identification information, and changing the settings of the inverter based on the extracted control parameter, using at least one processor. [Effects of the Invention]

[0009] According to the present invention, inverter control parameters that may be limited by the combination of the motor and inverter can be easily set simply by using images of the nameplates of the motor and inverter. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] 1 is a schematic diagram of an inverter setup system according to an embodiment of the present invention. As shown in this figure, the inverter setup system includes a motor 1, an inverter 2 capable of controlling the rotation speed of the motor 1, and a device (e.g., a smartphone) 3 capable of directly or indirectly outputting a command to change the settings of the inverter 2 to the inverter 2 by taking images of the nameplates 11 and 21 of the motor 1 and the inverter 2.

[0013] A nameplate 11 on which identification information of the motor 1 is clearly written is attached to the motor 1, and a nameplate 21 on which identification information of the inverter 2 is clearly written is attached to the inverter 2.

[0014] FIG. 2 is a diagram showing an example of a nameplate 11 of the motor 1. The nameplate shown in this figure lists, as identification information for the motor 1, a manufacturer name 111, a product name 112, a model (type number) 113, a voltage 114, a frequency 115, a rated rotation speed 116, and a rated current 117 of the motor 1, a first bearing ID 118 indicating identification information for a first bearing (bearing) used in the motor 1, a second bearing ID 119 indicating identification information for a second bearing (bearing), a serial number 120 and year of manufacture 121 of the motor 1, and a serial number (serial number) 125 of the motor 1. Although not described further, similar identification information, such as the manufacturer name, model (type number), serial number, and year of manufacture, is also listed on a nameplate 21 of the inverter 2 as identification information for the inverter 2. It is sufficient to identify the motor 1 by combining some of the identification information shown here; not all of the identification information is required to identify the motor 1.

[0015] The device 3 includes a camera 31 for photographing the nameplates 11 and 12, a processor (e.g., a microprocessor) for performing arithmetic processing, a memory for storing programs and data executed by the processor, and a communication device 35 for connecting to other devices and networks including the inverter 2 and the intermediate terminal 4. The device 3 may be, for example, a portable terminal (mobile communication terminal) with a communication function, such as a smartphone or a tablet. As shown in FIG. 1 , the device 3 preferably includes a positioning antenna 38 for receiving signals from positioning satellites and a receiver 37 for calculating the position of the device 3 based on signals from multiple positioning satellites received by the positioning antenna 38 (i.e., a satellite positioning system). The position data calculated by the receiver 37 may be transmitted to an external server (not shown) and treated as the positions of the motor 1 and the inverter 2.

[0016] It is preferable to connect the device 3 and the inverter 2, and the device 3 and the intermediate terminal 4, using short-range wireless communication such as Bluetooth, and it is preferable to connect the intermediate terminal 4, which may be equipped with a PLC (Programmable Logic Controller), and the inverter 2 using industrial wired communication such as Modbus, a communication protocol for PLC.

[0017] The text conversion unit 32, database (DB) reference unit 33, and parameter setting unit 34 shown in the device 3 in FIG.

[0018] The text conversion unit 32 receives the nameplate image captured by the camera 31, recognizes text portions within the image, and performs a process (OCR process) to convert the text portions into text data. Here, the image of the nameplate 11 of the motor 1 is referred to as a motor nameplate image (first nameplate image), and the image of the nameplate 21 of the inverter 2 is referred to as an inverter nameplate image (second nameplate image). Among the text data extracted from the motor nameplate image by the text conversion unit 32, that related to the identification information of the motor 1 is referred to as motor identification information (first identification information), and among the text data extracted from the inverter nameplate image by the text conversion unit 32, that related to the identification information of the inverter 2 is referred to as inverter identification information (second identification information). The text conversion unit 32 outputs the motor identification information and inverter identification information extracted from the motor nameplate image and the inverter nameplate image to the DB reference unit 33.

[0019] The DB reference unit 33 executes a process of registering input data (input data) in a database (DB) 36, and a process of referencing data in the DB 36 based on the input data and extracting data (output data) corresponding to the input data. Examples of the input data include motor identification information (first identification information) and inverter identification information (second identification information) obtained by the text conversion unit 32, and position information of the device 3 (position information of the motor 1 and inverter 2) calculated by the receiver 37. Examples of the output data include control parameters of the inverter 2 (e.g., maximum frequency, motor constants, etc.).

[0020] The DB 36 can be stored in the device 3 or in an external terminal (e.g., a server) communicatively connected to the device 3. That is, although the DB 36 in FIG. 2 is shown as being external to the device 3, it may also be mounted on the device 3.

[0021] FIG. 3 shows an example of a transmission form in which DB 36 stores input data from device 3. Transmission form 361 in this figure stores input data from device 3 (also referred to as "control parameter query"), and can store motor identification information (manufacturer name, model, serial number, year of manufacture), inverter identification information (manufacturer name, model, serial number, year of manufacture), and location information of device 3 (country / region, coordinates). Of these, the coordinates of device 3 are location information calculated by receiver 37, and are treated as location information of motor 1 and inverter 2. The location information of device 3 may also include information on the country / region in which positioning was performed by receiver 37.

[0022] 4 shows an example of an attribute database stored in DB 36. The illustrated attribute database 362 stores control parameters (in the illustrated example, motor constants and maximum frequency, which are information not listed on the nameplate) associated with each combination of motor identification information (in the illustrated example, manufacturer name, model, and serial number) and inverter identification information (in the illustrated example, manufacturer name, model, serial number, and manufacturing year). It is preferable that each control parameter be acquired in advance, taking into consideration the combination of motor and inverter identification information and the respective information not listed on the nameplate, and stored in attribute database 362. For combinations with different motor and inverter identification information, the control parameters may be different or the same. As shown in the illustrated example, information on restricted countries (country and region) may also be associated in addition to the control parameters.

[0023] The motor constants and maximum frequency stored as control parameters in the attribute database 362 are not listed on the nameplate. The "motor constants" are not listed on the nameplate of the motor, and the "maximum frequency" is the smaller of the maximum frequencies of the motor and inverter for the combination of the motor and inverter.

[0024] Motor constants are used to correct slip frequency when sensorless vector control is used in a motor drive system, and are necessary information for precisely controlling the motor's rotation speed and torque. While autotuning can be used instead of motor constants, it has the following limitations and is therefore undesirable. First, autotuning can be performed using either rotating or non-rotating measurements. In rotating measurements, the operating pattern for the measurement is determined by the inverter. Therefore, if the motor is incorporated into a device (such as a crane), measurements may not be possible if the operating pattern deviates from the mechanical constraints of the device. On the other hand, non-rotating measurements do not have such limitations, but some of the multiple parameters related to motor constants, such as no-load current and moment of inertia, cannot be obtained, and these unobtainable parameters must be determined.

[0025] DB36 uses the motor identification information and inverter identification information input from device 3 (i.e., the data stored in the transmission form of Figure 3) to extract control parameters corresponding to the combination of the motor identification information and the inverter identification information from the attribute database, and outputs the extracted control parameters to device 3 as output data.

[0026] When outputting control parameters to device 3, DB 36 may be provided with a function for determining whether the country or region in which motor 1 and inverter 2 are installed is a specified country or region (e.g., a country subject to export control restrictions) based on the country and region information in the transmission form, and restricting transmission of output data to device 3 if the country or region falls under that category. This determination may be based not only on the country or region, but also on either motor identification information or inverter identification information, or may be combined with the country or region. For example, for input data from an inverter with a frequency of 600 Hz or higher, the control parameters (output data) for that inverter may not be transmitted, and device 3 may be notified that the control parameters cannot be transmitted due to the inverter frequency.

[0027] 5 shows an example of an inquiry management database stored in DB 36. The illustrated inquiry management database 363 can store a number (inquiry number) assigned each time a control parameter inquiry (input of input data including motor identification information and inverter identification information) is made from device 3, the date (registration date) on which the inquiry number was registered in inquiry management database 363, the location information (country / region, coordinates) of device 3 included in the inquiry, the control parameters (motor constants, maximum frequency) transmitted by DB 36 in response to the inquiry, and the estimated lifespan (lifespan information) of the motor and inverter related to the inquiry.

[0028] "Location information" is information transmitted from device 3 that may include the coordinates and country / region of device 3.

[0029] The “transmission contents” are the input data of the device 3 (motor identification information and inverter identification information) and the control parameters extracted using the attribute database 362 .

[0030] The "estimated lifespan" is calculated based on, for example, the manufacturing year, serial number, manufacturer name, and model of the motor and inverter contained in the input data of device 3. For example, this information can identify the components used in each motor and inverter, and the estimated lifespan of the motor or inverter can be calculated based on the lifespan (e.g., average lifespan) of the components and the start date of use. The lifespan of the component with the shortest lifespan among the components used in the motor or inverter may be used as the estimated lifespan of the motor or inverter. If the component with the shortest lifespan is replaced, the lifespan of the component with the second shortest lifespan may be used as the next estimated lifespan of the motor or inverter. In consideration of this, information on the replacement date of each component used in the motor or inverter may be stored in DB 36. However, the estimated lifespan does not necessarily need to be calculated, and does not need to be transmitted to device 3. Furthermore, the estimated lifespan may be calculated for at least one of the motor and inverter. The calculation of the estimated lifespan may be performed by a terminal such as a server on which DB 36 is stored, or by device 3 if DB 36 is stored in device 3.

[0031] When the DB reference unit 33 receives the control parameters (output data) from the DB 36, it outputs them to the parameter setting unit .

[0032] The parameter setting unit 34 generates a setting command for reflecting the control parameters acquired from the DB reference unit 33 in the control of the inverter 2, and outputs the setting command to the communication device 35. The timing of outputting the setting command to the communication device 35 may be determined by the user of the device 3 or by the device 3 according to a program. The parameter setting unit 34 may also be configured to be able to correct the setting command in response to input from the user of the device 3 or the device 3. This correction may involve, for example, adjusting the control parameters to match the characteristics of the motor load (mechanical device). For example, in the case of a heavy load, correcting the rotation speed to reduce the rotation speed at the start and end of operation can suppress the occurrence of vibrations associated with the start and end of operation. In other words, since motor loads often have different characteristics for each user, it is preferable to be able to correct the setting command in accordance with the characteristics of each load. The setting command may be transmitted directly from the communication device 35 to the inverter 2, or may be transmitted from the communication device 35 to the inverter 2 via an intermediate terminal (e.g., a PLC) 4 capable of communicating with the device 3 and the inverter 2. The parameter setting unit 34 can include information on which method to use in the setting command, and the communication device 35 outputs the setting command in accordance with the information. For example, if the inverter 2 does not have a function for communicating with the device 3, it is preferable to output the setting command via the intermediate terminal 4.

[0033] Next, the processing executed by the device 3 (processor) configured as described above will be described. FIG. 6 is a flowchart of a first processing that can be executed by the device 3.

[0034] When the process starts, the device 3 inputs a nameplate image of the motor 1 (motor nameplate image (first nameplate image)) and a nameplate image of the inverter 2 (inverter nameplate image (second nameplate image)) (S101). Each nameplate image is taken, for example, by the camera 31 mounted on the device 3, but may also be taken by another camera or transmitted from another device.

[0035] Next, device 3 (text conversion unit 32) performs OCR processing on the motor nameplate image and the inverter nameplate image. Through this processing, device 3 (text conversion unit 32) extracts motor identification information (e.g., manufacturer name, model, serial number, and year of manufacture of motor 1) as text data from the motor nameplate image, and also extracts inverter identification information (e.g., manufacturer name, model, serial number, and year of manufacture of inverter 2) as text data from the inverter nameplate image (S102).

[0036] Next, device 3 (DB reference unit 33) transmits the motor identification information and inverter identification information extracted from the nameplate image to DB 36. Upon receiving this input of data, DB 36 searches and identifies a combination of the motor identification information and inverter identification information of the data in attribute DB 362, extracts the control parameters (motor constant, maximum frequency) of inverter 2 corresponding to the identified combination, and outputs them to device 3 (S103). Note that the motor identification information and inverter identification information input from device 3 may be stored in transmission form 361 (FIG. 3) in DB 36, and then searched for in attribute DB 362.

[0037] The device 3, which has received the control parameters from the DB 36, transmits the control parameters (motor constant, maximum frequency) from the DB reference unit 33 to the parameter setting unit 34, which then generates a setting command from the control parameters (motor constant, maximum frequency) and transmits the setting command to the communication device 35. The communication device 35, which has received the setting command, transmits the setting command to the inverter 2 (S104). This changes the settings of the inverter 2 based on the control parameters (motor constant, maximum frequency) that are in line with the combination of the motor 1 and inverter 2 and the information not listed on the nameplate.

[0038] In the inverter setup system configured as described above, the control parameters of the inverter 2 for each combination of motor and inverter (i.e., combination of motor identification information and inverter identification information) are acquired in advance from the combination and the non-nameplate information for that combination, and stored in the attribute database 362 in the DB 36. Therefore, by transmitting the motor identification information and inverter identification information acquired from the nameplate image of the motor 1 and inverter 2 from the device 3 to the DB 36, the control parameters corresponding to the combination of the motor identification information and the inverter identification information are identified in the attribute database 362, and the control parameters are output to the device 3. In other words, simply by transmitting the identification information obtained from the nameplate image of the motor 1 and inverter 2 from the device 3 to the DB 36, it is possible to acquire control parameters that take into account the combination of identification information and the non-nameplate information, and the settings of the inverter 2 can be easily changed using the control parameters.

[0039] In particular, although the motor constants are not listed on the nameplate, when the inverter 2 controls the rotation speed of the motor 1 using sensorless vector control, this embodiment makes it possible to use the motor constants to correct the slip frequency of the motor 1 without auto-tuning. In other words, simply by acquiring nameplate images of the motor 1 and inverter 2, the rotation speed and torque of the motor 1 can be easily and accurately controlled.

[0040] Furthermore, the maximum frequency is information not printed on the nameplate that is determined by the combination of the motor and inverter, but according to this embodiment, the value of the smaller maximum frequency for the combination of motor and inverter is output from DB 36 as the maximum frequency (control parameter) and used to control inverter 2, so that the rotation speed of motor 1 can be controlled at the maximum frequency appropriate for that combination. In other words, inverter control appropriate for the combination of motor 1 and inverter 2 can be performed simply by acquiring nameplate images of motor 1 and inverter 2.

[0041] Next, we will explain another process executed by the device 3 (processor) configured as above. Figure 7 is a flowchart of a second process that can be executed by the device 3. Note that parts that are the same as those in the first process explained above will be assigned the same reference numerals, and explanations thereof may be omitted.

[0042] The second process is characterized in that the position information of the motor 1 and the inverter 2, obtained by the receiver 37, is transmitted from the device 3 to the DB 36 and stored therein.

[0043] In S101A, the device 3 inputs the positioning information (position data) calculated by the receiver 37, the nameplate image of the motor 1 (motor nameplate image (first nameplate image)), and the nameplate image of the inverter 2 (inverter nameplate image (second nameplate image)).

[0044] In subsequent S105, the device 3 transmits the positioning information (position data) acquired in S101A to the DB 36 together with the identification information of the motor 1 and the inverter 2 extracted in S102. The transmitted positioning information is associated with the identification information of the motor 1 and the inverter 2 and stored in a transmission form 361 in the DB 36. A description of the processing thereafter will be omitted.

[0045] As in the second process, by storing the positioning information of the device 3 as position data of the motor 1 and the inverter 2 in the DB 36, the locations of the motor and the inverter and their respective identification information can be registered in the DB 36. In other words, according to this embodiment, it is possible to easily grasp where in each country what kind of motor and inverter combinations exist. This makes it easier to plan maintenance for the motors and inverters, for example.

[0046] Next, a description will be given of still another process executed by the device 3 (processor). FIG. 8 is a flowchart of a third process that can be executed by the device 3.

[0047] The third process is characterized in that a setting command is sent from the device 3 to the inverter 2 via the intermediate terminal 4. The intermediate terminal 4 is a terminal that can communicate with the device 3 and the inverter 2, and plays a role in changing the settings of the inverter 2 on behalf of the device 3.

[0048] In S104A, the device 3 transmits the control parameters (motor constant, maximum frequency) from the DB reference unit 33 to the parameter setting unit 34, and the parameter setting unit 34 generates a setting command from the control parameters (motor constant, maximum frequency) and transmits the setting command to the communication device 35. The communication device 35, having received the setting command, transmits the setting command to the intermediate terminal 4, and then transmits it to the inverter 2 via the intermediate terminal 4.

[0049] By outputting a setting command to the inverter 2 via the intermediate terminal 4 in this manner, it becomes possible to change the inverter settings even when the inverter 2 does not have the ability to communicate with the device 3 or when the inverter 2 is far from the device 3.

[0050] Next, a description will be given of still another process executed by the device 3 (processor). FIG. 9 is a flowchart of a fourth process that can be executed by the device 3.

[0051] The fourth process is characterized in that the start time of use of the motor 1 and inverter 2 is registered in the DB 36, and the lifespan of the motor and inverter registered in the DB 36 is predicted using the information at the start time of use.

[0052] In S105A, the device 3 transmits information about the start of use of the motor 1 and the inverter 2 to the DB 36, along with the position information of the motor 1 and the inverter 2. As the information about the start of use, for example, information about the first date and time when a combination of a motor and an inverter having the same identification information transmitted data to the DB 36 can be used. Alternatively, for example, the first "registration date" (year, month, and day) for a combination of a motor and an inverter having the same identification information in the inquiry management DB 363 can be used as the start of use.

[0053] In the subsequent step S106, the device 3 receives the lifespan information and maintenance plan of the motor 1 and the inverter 2 from the DB 36. The inquiry DB 363 of the DB 36 stores the lifespan information (estimated lifespan) of the motor 1 and the inverter 2 calculated based on the identification information of the motor 1 and the inverter 2 and the time of start of use, and can transmit this lifespan information to the device 3.

[0054] In addition to lifespan information, the inquiry DB 363 also stores location information for motors and inverters. By using this data, it is possible to estimate, for example, the number of motors and inverters in each region that will reach the end of their lifespan within a specified period and the number of replacement parts (required inventory of parts) that will be required when their lifespan is reached. Therefore, this information can be used to create maintenance plans for motors and inverters in each region and to provide customers with timely maintenance and replacement proposals based on these plans. The number of replacement parts required to repair motors and inverters that have reached the end of their lifespan and the calculation of the maintenance plan can be performed by a server equipped with DB 36.

[0055] In addition to the lifespan information of the motor and inverter, lifespan information of parts mounted on at least one of the motor and inverter (for example, bearings of the motor) may be stored in DB 36 as information associated with the motor or inverter.

[0056] The present invention is not limited to the above-described embodiments, and includes various modifications within the scope of the gist of the present invention. For example, the present invention is not limited to those having all of the configurations described in the above-described embodiments, and includes those in which some of the configurations are omitted. Furthermore, it is possible to add or replace some of the configurations of one embodiment with the configurations of another embodiment.

[0057] In the above embodiment, the identification information of the motor and inverter is extracted by OCR processing of a photographed image of the nameplate, but a configuration may also be adopted in which a two-dimensional code with embedded identification information is attached to the motor or inverter, and the identification information of the motor or inverter is extracted from a photographed image of the two-dimensional code.

[0058] Furthermore, the configurations of the device 3 and DB 36, as well as the functions and execution processes of the configurations, may be partially or entirely implemented by hardware (for example, by designing logic for executing each function as an integrated circuit). The configurations of the device 3 and DB 36 may also be implemented as programs (software) that are read and executed by an arithmetic processing unit (for example, a CPU) to implement the functions of the control device. Information related to the programs may be stored in, for example, semiconductor memory (flash memory, SSD, etc.), magnetic storage devices (hard disk drives, etc.), and recording media (magnetic disks, optical disks, etc.).

[0059] In addition, in the above description of each embodiment, the control lines and information lines are those that are considered necessary for the description of the embodiment, but they do not necessarily represent all the control lines and information lines related to the product. In reality, it can be considered that almost all components are interconnected.

[0060] In the above embodiment, the control parameters of the inverter are obtained based on identification information obtained from nameplate images of the motor and inverter, and setting changes that reflect these control parameters are made to the inverter. However, these setting change processes may be omitted, and only a series of processes for sending life information and maintenance plans for motors and inverters in various locations to device 3 may be performed.
