In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which can be made by a person skilled in the art without creative efforts, based on the described embodiments of the present invention fall within the protection scope of the present invention.
Unless otherwise defined, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The terms "first," "second," and the like, as used in this disclosure, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. Likewise, the terms "a," "an," or "the" and similar terms do not denote a limitation of quantity, but rather denote the presence of at least one. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
For a multi-mover conveyor, each mover should be individually numbered and individually controlled by the control system to achieve accurate conveyance when the system is running.
The multi-rotor conveying system can determine the rotor number in a mode of internal software coding when a motor is started, in this case, at least one difference exists between hardware of different rotors, when the system is started, own information of the rotors is sent to a controller, the controller numbers the rotors according to the difference of own information of the rotors, thus, all the rotors are required to be manufactured differently, and if the rotors are the same, the rotors cannot be numbered; in addition, for the software coding mode, when the power is suddenly cut off, the software cannot store each rotor number and the corresponding station, and the process loss phenomenon occurs at the moment. After the machine is started again, the previous process information cannot be restored and can only be started from the initial station. Thus, not only is the product wasted, but also the processing time is wasted.
Fig. 1 shows a schematic block diagram of a numbering system of an embodiment of the present disclosure, as shown in fig. 1, a numbering system 1000 of an embodiment of the present disclosure may comprise: at least one tag read-write module 200, each configured to read information of a tag of each of the plurality of components and send the information of the tag to the controller; a position acquisition device 300 configured to generate a position signal according to the position of each of the plurality of components and to provide the position signal to the controller; and a controller 100 for receiving the information of the tag and the position signal, determining the position information of the component according to the position signal, generating a mapping table of the information of the tag of the component and the position information, and storing the mapping table, wherein the information of the tag of the components in the mapping table corresponds to the position information of the components one by one.
For example, a component of an embodiment of the present disclosure may be a mover having a tag, e.g., an electronic tag, a Radio Frequency Identification (RFID) tag, disposed thereon, which may include a chip and a coil antenna, e.g., may be an RFID tag sticker, affixed to the mover. The information of the tag may be written to the chip in advance, or may be written to the chip by using the tag read-write module, but when the information of the tag is read by using the tag read-write module to generate the mapping table, the information of the tag is already written.
For example, the tag information may be unique digital ID information, and the digital ID information of each of the movers is different, so that the different movers can be distinguished, for example, the digital ID information may be 0, 1,2, 3, etc., as long as the digital ID information of each of the movers is different, which is not limited by the embodiment of the present disclosure.
For example, in the numbering system of the embodiment of the present disclosure, one of the at least one tag read/write module may be provided in the position acquisition apparatus 300, and the tag read/write module may be configured to read information of a tag of the component when the device is operated, and simultaneously transmit the information of the tag and the position signal to the controller.
For example, during the running of the movers, the position obtaining device can obtain the position signal of each of the movers, the tag read-write module can scan the tag on the movers to read the tag information of the movers, the two signals can be sequentially transmitted to the controller through the same port or channel, or the corresponding channels are simultaneously transmitted to the controller, the controller can identify the position signal of the mover where the tag information of the mover corresponds to the tag information through the transmission channels of the two signals, and the position of the mover where the corresponding tag information is located can be known, so that the mapping table is updated. Here, updating may refer to updating the position information of the mover corresponding to the tag, for example, when the mover with the tag 1 is at the coordinate 3 at the beginning and the mover with the tag 1 is at the coordinate 9 at a certain moment, the mapping update of 1-3 in the mapping table may be 1-9, or it may also be understood that the information of the tag of the mover with the same coordinate is changed, and any one or both of the mapping tables may be regarded as updating the mapping table, which is not limited by the embodiments of the present disclosure. When a mover is found to be added or deleted, the tag is rescanned to generate a mapping table, and both the information and the position information of the tag of the mover in the mapping can be updated.
For example, the position acquisition means is configured to send information of the tag and position information of each of the plurality of components to the controller at regular intervals, for example, every 66-333us, and the controller updates the map table based on the received information of the tag and the position information. Thus, each time the machine is turned off, the mapping table is the last updated mapping table.
Alternatively, the controller may store mapping tables at a plurality of times according to time for data security and for convenience of error checking, and other mapping tables are stored as backup data in addition to the latest mapping table.
For example, one of the tag read/write modules 200 may be provided in a mobile terminal, when the apparatus is turned on for the first time without storing a mapping table in the controller and without performing a moving operation on the mover, at this time, an operator may scan a tag of each mover using the mobile terminal to read information of each tag, and the position obtaining device obtains a position signal of each mover, and the controller determines position information of the mover according to the position signal. For example, if the guide rail is a straight line, the mover is sequentially arranged from the start point, the information of the tag of the mover needs to be sequentially scanned from the start point to the end point when scanning the information of the tag of the mover, and the position information of the mover is also sequentially arranged from the start point, so that the controller sequentially corresponds the information of the tag of the mover to the position information to generate the mapping table.
For example, 10 movers are provided on the entire guide rail, and assuming that the forefront, that is, the coordinates of the mover closest to the start point is 0 and the coordinates of the other movers may be 1,2, … …, the labels of the movers should be scanned sequentially from the start point to the end point when the labels are scanned, so that the controller can correspond the position information of the mover at the coordinates 0 to the information of the first label scanned, the position information of the mover at the coordinates 1 to the information of the second label scanned, and the position information of the mover sequentially up to the last coordinates 9 to the information of the last label scanned, thereby generating a map of one-to-one correspondence of the information of the labels and the position information, and storing the map.
For example, the tag read-write module may include: a reading section configured to read information of a tag of the component; and a communication part configured to communicate with the controller to transmit information of the tag.
For example, the tag read-write module may further include: and a writing section configured to write information to a tag of the component.
Alternatively, when information in the tag of the mover is not yet input, ID information may be written to the tag using the mobile terminal equipped with the tag read-write module to identify the number of the mover, or ID information may be written to the tag using the position acquisition device, which is not limited by the embodiment of the present disclosure.
For example, the component may be a mover, and the position acquisition device is disposed on the stator, and a magnetic grating ruler or a grating ruler is disposed on the mover.
For example, the position acquisition device may further include: and a position feedback part including a plurality of magnetic sensors configured to generate a position signal according to a position of each of the plurality of parts and to transmit the position signal to the controller, the magnetic sensors of the position feedback part sensing a change in a magnetic field when the mover with the magnetic grating ruler passes through the position feedback part, thereby generating a position signal, and the controller can determine position information of the mover according to the position signal. For example, the magnetic sensor of the position feedback part may be laid at intervals to fill the running rail of the whole mover, thereby precisely returning the position information of the mover.
For example, the position acquisition device may further include a storage section configured to store the position signal and/or information of the tag.
For example, since the position obtaining device in the embodiment of the present disclosure is further provided with a tag reading unit, when the system is started up each time, the position obtaining device may obtain a position signal of each mover, and send the position signal to the controller, the controller counts the number of the movers according to the position signal, when the number of the movers is found to be different from the number of the movers in the latest mapping table, the controller determines that the system is wrong, the movers may be missing or increased, if the position of the movers is controlled according to the original mapping table, it is obvious that an operation error such as a collision of the movers occurs, at this time, the controller may send a wrong prompt message to an operator, for example, a sound, information, an indicator lamp, etc., so that the operator may stop running the movers in the system in time, and re-scan and read the tag information of the movers and obtain the position information of the movers, and re-generate the mapping table again, or may re-scan and read the tag information of the movers and obtain the position information of the movers by using the position obtaining device. Or, during self-checking, the position acquisition device may acquire the information of the tag of each mover in addition to the position signal, and send the position signal and the information of the tag to the controller simultaneously or sequentially, where the controller determines the position information according to the position signal, compares the paired position information and the information of the tag with the mapping table, and determines that the problem of missing or adding of the movers occurs or the position information of the mover corresponding to the tag does not correspond to the position information of the mover corresponding to the tag once the number of movers is found out to be not correct, and then the mobile terminal or the position acquisition device is required to rescan update the mapping table.
In this way, in the numbering system according to the embodiment of the disclosure, the tag is disposed on the mover, the information of the tag is scanned and acquired by using the mobile terminal or the position acquisition device having the tag acquisition module, and the position signal of the mover is acquired by using the position acquisition device, and after the position information is determined according to the position signal, the mapping table is generated by using the information of the tag of the mover and the position information of the mover. Further, in operation, the information of the tag in the mapping table and the position information of the mover are updated at regular time, so that the latest position of the mover can be obtained, and accurate control can be realized. And the numbering system can also perform self-checking at each start, judge whether the rotor is missing or added by acquiring the position signal of the rotor or both the position information of the rotor and the information of the tag, and update or regenerate the mapping table if the rotor is missing or added, so that the error is found out in time, the error is corrected, the defects of poor control and the like of the rotor are avoided, and the accurate control of the rotor is realized.
Embodiments of the present disclosure further provide a numbering method, which uses any of the above numbering systems, for brevity, the details of the composition of the numbering system will not be described herein, and reference may be made specifically to the above embodiment, as shown in fig. 2, and the numbering method may include:
step S1, reading information of labels of each of the plurality of components by using the label read-write module, and sending the information of the labels to a controller;
step S2 of generating a position signal from the position of each of the plurality of components by the position acquisition means, and providing the position signal to the controller;
step S3, the controller receives the information of the label and the position signal, determines the position information of the component according to the position signal, generates a mapping table of the information of the label of the component and the position information and stores the mapping table,
the above steps are performed before the device is started for the first time and the mapping table is not stored in the controller or after the controller finds that the mapping table has an error.
For example, the steps S1 and S2 may be performed when the system is first powered on and the controller does not store the mapping table, and before the control operation is not performed on the mover, and these two steps may be performed simultaneously or in a first-to-last manner, which is not limited in the present disclosure, and in step S3, the controller generates and stores the mapping table.
Alternatively, when the controller finds that the number of the movers is not matched with the mapping table in the power-on self-test, or the mapping of the position information and the information of the tag is not matched, the operator may stop the operation control of the movers, and execute steps S1 to S3 again, so that the correct mapping table is stored in the memory of the controller.
Alternatively, for step S1, one of the tag read/write modules may be provided in the mobile terminal, may be information that an operator holds the mobile terminal to scan and read the tag, or may also be information that the tag read/write module in the position acquisition device is used to read the tag. Compared with the method that the position acquisition device reads the information of the tag, the mobile terminal is used for reading the information of the tag, an operator can walk from one end of the system to the other end to sequentially read the tag of the mover, other errors of the system can be checked while the information of the tag is read, if the tag is required to be attached infirm or the tag cannot be read, the errors can be corrected timely, the accuracy of generating a mapping table for the mover can be guaranteed, the control precision of the mover is further improved, reworking and the like are avoided.
For example, if the guide is a straight line, the movers are sequentially arranged from the start point, the information of the tags of the movers needs to be sequentially scanned from the start point to the end point when scanning the information of the tags, and the position information of the movers is also sequentially arranged from the start point, so that the controller sequentially corresponds the information of the tags to the position information to generate the mapping table. For example, 10 movers are provided on the entire guide rail, and assuming that the forefront, that is, the coordinates of the mover closest to the start point is 0 and the coordinates of the other movers may be 1,2, … …, the labels of the movers should be scanned sequentially from the start point to the end point when the labels are scanned, so that the controller can sequentially know that the position information of the mover at the coordinates 0 corresponds to the information of the first label scanned, the position information of the mover at the coordinates 1 corresponds to the information of the second label scanned, the position information of the mover at the last coordinates 9 corresponds to the information of the last label scanned, thereby generating a map of one-to-one correspondence of the information of the labels and the position information, and storing the map.
For example, the position obtaining device may further include a tag read-write module, and the numbering method may further include: controlling the position acquisition means to generate a position signal in accordance with the position of each of the plurality of components and read information of the tag of each of the plurality of components at the timing when the apparatus is operating; transmitting the position signal and information of the tag to the controller; the controller receives the position signal and the information of the tag sent by the position acquisition device, determines the position information from the position signal, and updates the mapping table according to the position information and the information of the tag.
For example, the numbering method of the embodiments of the present disclosure may further include: each time when the device is started, controlling the position acquisition device to send a position signal of each part to the controller; the controller determines the position information based on the position signals and determines whether there is an error based on the position information of the plurality of parts and a recently updated mapping table.
For example, the controller determining the position information according to the position signals, and determining whether there is an error according to the position information of the plurality of the parts and the latest updated mapping table may include: the controller counts the number of the parts according to the position information; comparing the number of the components with the number of the mappings in the mapping table; when the number of the components is not matched with the number of the mappings in the mapping table, the controller judges that an error occurs and sends prompt information to an operator.
For example, when the controller receives the position information of 10 movers, but the mapping table stores the mapping of 11 movers, the controller determines that the two are not matched, and a problem of mover deletion may occur; or the controller receives the position information of 12 movers, and the position information is not matched with the mapping of 11 movers stored in the mapping table, so that the problem of increasing the movers can occur; therefore, the controller can judge that errors related to the number of the rotor occur, so that accurate control of the rotor action cannot be realized, an operator can be prompted in a sound, text and alarm mode, and the operator can stop the operation of the rotor and rescan the label to generate a mapping table. Therefore, errors are found out in time, the errors are corrected, and precise control of the rotor is realized.
Alternatively, the numbering method may further include: when the device is started up each time, the position acquisition device is controlled to send a position signal of each part and information of a label to the controller; the controller determining the position information according to the position signals, and determining whether there is an error according to the position information of the plurality of components, the information of the tags, and the latest updated mapping table, including: mapping the position information and the label information of each component with the mapping table, and when the position information and the label information of each component are not matched with all the mappings, judging that errors occur by the controller, and sending prompt information to an operator. For example, when the coordinate 1 in the mapping table corresponds to the mover No. 9, but the returned information is that the coordinate 1 corresponds to the mover No. 8, if there is no mapping identical to that of the corresponding 1-8, it is determined that the mapping table is not matched with the mapping table, and there is a possibility that there is a mover error, so that a prompt message is sent, and steps S1-S3 are executed.
For example, one of the tag read/write modules is provided in the mobile terminal, and after the operator receives the prompt information, the operator suspends all operations and scans the tag of each of the plurality of components with the tag read/write module in the mobile terminal, and the steps S1 to S3 are performed.
The embodiment of the disclosure also provides a magnetic levitation system, comprising: a numbering system as described in any of the above; the stator is provided with the position acquisition device; the rotor is the component and is provided with the tag; and the mobile terminal is provided with the tag reading and writing module.
For example, the magnetic levitation system may further include: and a guide rail along which the mover moves, wherein each of the position acquisition devices includes a plurality of magnetic sensors and a tag reading unit.
For example, the mover may be provided with a magnetic grating ruler, the position acquisition includes a plurality of magnetic sensors disposed on the stator at certain intervals, when the mover passes the magnetic sensors, the magnetic field is changed, a position signal is generated, and the controller acquires the position signal and then acquires position information about the mover.
Alternatively, a grating ruler can be further arranged on the mover, and moire fringes are utilized to detect position information of the mover.
Alternatively, the numbering system and the numbering method of the embodiment of the disclosure can be used for a multi-subsystem other than a magnetic levitation system, and the system and the method are used for numbering the movers, so that precise control of the movers is realized.
The numbering system, the numbering method and the magnetic levitation system of the embodiment of the disclosure can have at least one of the following technical effects:
(1) The information of the tag of each rotor is read through the tag reading module, the position signal of each rotor is obtained through the position obtaining device, and the controller generates and stores the mapping table according to the information and the position signal of the tag, so that the rotors can be numbered and stored without different rotor manufacturing, the situation that the rotors cannot be numbered due to uncharged rotors is avoided, and the phenomenon that the process is lost due to the fact that software cannot save each rotor number and the corresponding station thereof when sudden power failure occurs is avoided.
(2) When the system operates, the position acquisition device can send the information of the tag of the rotor and the position signal of the corresponding rotor at regular time, so that the controller can be according to the mapping table at regular time, and therefore, when sudden power failure does not occur, the software cannot save the serial numbers of each rotor and the corresponding stations thereof, and the phenomenon of process loss is caused.
(3) Because the latest mapping table is stored in the controller, the position is determined without the need of timing information transmission of a rotor, and when the machine is started again, the previous process information is directly determined according to the mapping table, so that the situation that the previous process information cannot be restored and can only be performed from an initial station is avoided.
(4) Because the mapping table is stored in the controller, each time the machine is started, whether the rotor is in a missing state or an added state can be determined according to the position signals or the position signals sent by the position acquisition device and the information of the labels, but the mapping table is not updated, so that the situation that the rotor cannot be accurately controlled due to the fact that the rotor is in a missing state or an added state is avoided, error correction is timely carried out, and more accurate control of the rotor is achieved.
