As one of the motion sensors, the gravity acceleration sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when the motion sensor is stationary, and can be used for applications (such as horizontal and vertical screen switching, related games, magnetometer attitude calibration) for recognizing the attitude of hardware equipment, and related functions (such as pedometer and tapping) for vibration recognition; of course, the hardware device may also be configured with other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, an infrared sensor, and so on, which are not described herein again.
Those skilled in the art will appreciate that the terminal structure shown in fig. 1 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
Further, it should be noted that the component warehousing system may include at least one of an AGV (Automated Guided Vehicle) equipped with an automatic guiding device such as an optical device, an induction door body provided at a component transportation entrance (a warehouse entrance), a container for loading components, a server, and an RFID (Radio Frequency Identification) acquisition device provided between an empty container placement area and a loading point, in addition to the above-described structural components.
AGVs, also known as AGVs, are automated guided vehicles that utilize electromagnetic induction, laser, or magnet-gyro guidance, and can transport parts from a designated location to another designated location instead of transporting personnel.
The induction door body is arranged at the part conveying access, and is easy to understand that the part conveying access is arranged in an access channel between a cargo loading point and a storehouse where a storehouse is located. The induction door body can perform height scanning through height induction devices such as an infrared sensor and a 3D scanning device, and then height data from the ground of the entrance and the exit to the top of the AGV are obtained.
The container for loading the parts is provided with an RFID chip as an RFID label, the RFID chip is pre-stored with RFID information, and the RFID information can comprise at least one of part type, part number, part supplier identification, part specification data and container specification data of the loaded parts, and all the information can be used as part information. The container can be repeatedly used, can be made of iron or rigid plastics, and can be arranged into a cuboid or cage shape. It should be further noted that each container is unique, and the RFID tag provided by the container is also unique, and corresponds to a preset part type, so that no change is generated in transportation, shipment, and warehouse entry and exit of the whole logistics system, and the full data chain closed-loop control of the subsequent logistics system is ensured.
The server is a control center of the whole part warehousing system, can integrally control the whole warehousing transportation and even the running state of the whole logistics system through the communication data transmission of other parts, further summarizes data according to the obtained running state, knows the progress of product supply to each link, and helps to assist the stable running of the production link. On the other hand, the server can send various instructions to trigger the AGV, the acquisition device and the like, and control other components to stably operate according to the plan.
The RFID acquisition device is arranged between the empty container placing area and the loading point, can be directly integrated with the induction door body, also can be arranged between the induction door body and the loading point, or is arranged on the position area which is independently set between the induction door body and the empty container placing area, or can be directly arranged on the empty container placing area. The device can collect the preset RFID information of the empty container, further know the original part type loaded by the container when loading the part, and further timely and correctly supplement the part in the production and use process.
In conclusion, through the matching arrangement of all the components of the part warehousing system, the automation, unmanned operation and intelligent operation of part warehousing are realized, and the whole application of intelligent manufacturing and industry 4.0 to a logistics system is perfected.
It should be noted that the process and specific embodiment of the application component warehousing system of the present invention are substantially the same as the following embodiments of the application component warehousing method, and are not described herein again.
Referring to fig. 2, in an embodiment of the component warehousing method of the present invention, the method includes the following steps:
step S10, when the AGV carries a container loaded with parts, detecting the RFID label of the AGV container passing through the induction door body in real time through the induction door body arranged at the entrance of the warehouse to obtain the preset RFID information of the container, wherein the preset RFID information is the part information correspondingly recorded by a part supplier before shipment;
and step S20, recording warehousing information of the parts according to the preset RFID information obtained by detecting the RFID label in real time.
It should be noted that, in the existing logistics system, there is a process before the parts are put into storage, that is, the parts before being put into storage are checked and recorded manually, so as to ensure that the put-in quantity is consistent with the order issued by the supplier or the part list of the batch fed back by the supplier. Compared with the prior art, the automatic layout setting is carried out on the recording and checking of the part information, when the part information is stored and recorded, the part passes through the induction door body, the preset RFID tags of the containers for loading the parts on the AGV are identified, and the containers corresponding to all the RFID tags are unique, namely, the two RFID tags have a one-to-one correspondence relationship. The preset RFID label records part information loaded in the container and recorded by a part supplier before shipment, wherein the part information comprises part specifications, part quantity, part types, suppliers to which the parts belong and the like, and can also comprise container specifications. By acquiring the information of the loaded parts recorded by the RFID tags on each container and then storing and recording the information of the parts, a manufacturer can know how many parts are automatically put in storage. Optionally, when recording and storing the part information, the warehousing time, the number plate of the logistics vehicle transported during warehousing, the unit price of the part, and the like can be recorded.
The recording of the part information (preset RFID information) may be to acquire part specifications, part types, and part numbers included in the preset RFID information, and then record the part specifications, part types, and part numbers as warehousing information of the parts in a preset warehousing table. The preset table entry can be a data table in a database or a table file similar to Excel in a file.
It can be understood that, during the storage, the transportation operation of the AGV is still continuously performed, and then the actual recording process of the warehousing information is also dynamically performed, which requires the real-time update of the number of the warehoused components. The preset entry table may be a newly added blank table in the initial case, or may be a table recorded by the manufacturer and including the stock amount of all the parts in the warehouse when the last part warehousing operation is completed. The method can search keywords in a preset library table according to the part specification and the part type, the specific part specification and the part type are confirmed according to the serial number of a manufacturer for the part, if the same type is set for different part specifications of each part, common search needs to be carried out according to the part specification and the part type, and if the same type and different specifications also have different types, storage can be carried out only according to the part type. If the keywords can be found, parts of the same type can be known to be warehoused, the warehoused quantity corresponding to the keywords in the preset warehousing table can be determined, and the warehoused quantity can be added to the warehoused part quantity when the information of the warehoused parts is recorded, so that the updated warehoused quantity is obtained. On the contrary, if the keyword cannot be found, the part may not be accepted and put in storage in the present putting or in all previous putting operations (determined according to the initial condition of the preset putting table), and the category of the part needs to be set, that is, under the corresponding header, the part specification and the part type are stored, and meanwhile, the put-in quantity of the mapping newly built in the preset putting table after the association between the part specification and the part type is established, and the put-in quantity is the quantity of the part at this time. The specific implementation may include the following steps:
step S21, using the part specification and the part type as keywords to judge whether the preset entry table has the corresponding number of entries of the keywords; if yes, go to step S22; if not, go to step S23;
step S22, acquiring the warehousing quantity corresponding to the part specification and the part type from a preset warehousing table, and adding the warehousing quantity to the part quantity to update and store the warehousing quantity;
step S23, establishing a mapping relationship between the part specification and the part type and the part quantity, and storing the mapping relationship in the preset entry table.
The induction door body detects the unique RFID label corresponding to the container bearing the part product, the part product information can be read, and storage of warehousing information is achieved. In addition, the warehousing progress of the parts can be known in time, and convenience and directness are realized.
Further, based on the introduction about the part warehousing process, besides the record including the part information, the method also includes a verification process. Therefore, the part verification can be carried out according to the actual and estimated total weight of the part and/or the total height of the AGV added part before the step of recording the part specification, the part type and the part number as the warehousing information of the part into the preset warehousing table. The following examples are provided for the total weight of the parts used alone and the total weight of the joined parts and the total height of the AGV added parts.
For example, when checking is performed based on the actual and estimated total weight of the parts, the actual total weight of the container loaded with the parts to which the preset RFID information fed back by the AGV belongs may be received; and checking the parts borne on the AGV according to the part specification, the part type, the part quantity and the actual total weight, and recording the part specification, the part type and the part quantity serving as warehousing information of the parts into a preset warehousing table after the checking is finished. Specifically, when the total weight is used as a reference factor for verification, the estimated total weight of the parts loaded in the container can be estimated according to the part specification, the part type and the part number; judging whether the difference value between the actual total weight and the predicted total weight is within a floating range corresponding to the preset weight of the container or not; when the difference value is within the floating range, determining that the verification of the parts loaded on the AGV is finished; conversely, when the difference is not within the floating range, the verification is deemed unsuccessful. It will be appreciated that the parts have a strictly uniform weight specification, and given the specification, type and quantity, the total weight of all parts loaded with containers on the AGV can be estimated to give the expected total weight. The AGV may also be provided with a gravity sensor, and directly obtain the total weight of the parts and the container borne by the AGV in the actual transportation process, that is, the actual total weight, and when the verification is performed, because the total weight of the parts does not take the weight of the container into account, a corresponding floating range may be set based on the preset weight of the container, for example, the floating range proportion is 5%, and if the container is heavy 1 kg, the floating range is 1.05 kg to 0.95 kg. It is understood that the smaller the floating range ratio, the higher the accuracy. When the difference between the actual total weight and the predicted total weight is within the floating range, it is proved that the parts borne by the AGV are correct, and no careless situation occurs, and the verification can be considered to be completed.
On the other hand, in order to improve the accuracy and eliminate the problems of mistaken entry of parts of the same specification and the like, for example, the common check can be performed by combining parameters in the aspects of height and weight, and the execution process can be that the actual height data of the AGV passing through the induction door body is obtained on the basis of completing the check of the total weight; estimating estimated height data when the AGV carries the container loaded with the parts according to the part specification and preset AGV height data; judging whether the difference value between the actual height data and the predicted height data is within a preset range or not; and if so, determining that the verification of the parts loaded on the AGV is finished.
It should be noted that the overall height data of the current load-bearing part of the AGV can be obtained based on the specification of the container, and then the overall height data can be obtained by combining the overall height data with the known AGV height, so as to compare and check the overall height data with the actual height data obtained by the 3D scanning technology, and when the difference between the overall height data and the actual height data is not large, for example, the difference is less than or equal to a preset threshold or within a preset range, the overall height data can be considered to pass the check. It will be appreciated that the high level of validation allows for component verification in terms of quantity and type due to the strict mapping between containers and components. Therefore, the determination of the type and the number of the parts can be completed according to the actual height data of the AGV currently passing through the induction door body and the specification data, and once the height does not meet the verification condition, the type and/or the number are/is wrong. Through the combination of weight and height, the accuracy of part verification can be improved, and the accuracy of warehousing quantity and type is ensured.
The volume occupied by a single container can also be evaluated, and any container does not conform to the corresponding volume size and does not pass the inspection and acceptance. It should be noted that when the non-verification passes, an alarm may be sent to the server to notify the worker to go to the inspection. The scheme improves the process of checking and accepting the part in the automatic warehousing and realizes the automatic checking. In general, the intelligent logistics system is improved.
In other embodiments, scheduling settings may be made for the transport of the AGV. The AGV operation sequence can be a loading point, a storage position and an empty container placing area, and then returns to the loading point to cycle in sequence. It should be noted that, the empty container placing area and the storage location are both located in the storage, the loading point is located outside the storage, the AGV must pass through the induction door body in the reciprocating process, and in the process of passing through the induction door body twice in the adjacent process, if the AGV goes to load, the AGV must unload before, the height variation trend of the AGV is reduced, after the induction door body feeds back the height data of the two adjacent times, the server determines that the height variation trend is reduced, the AGV is scheduled and indicated, so that the AGV is triggered to go to the loading point to carry out part transportation. On the contrary, when the trend of height change is high, the server needs to trigger the AGV to go to the storage location for warehousing the parts.
The specification of the storage position can be only placed in an idle storage position, and the server records the types of the parts stored in the corresponding storage position. Furthermore, the type of the part to be warehoused can be determined before the part is warehoused, and the warehouse location where the type is located can be found according to the type of the part, so that the AGV can directly place the part into the idle warehouse location of the corresponding type. The storage positions can be numbered, the placing sequence is set according to the numbers, and coordination between the use and the storage of the parts is guaranteed.
When the parts are put into the warehouse according to the part types, after the verification is completed, the part types of the parts corresponding to the containers are determined according to the preset RFID information, so that the warehouse positions corresponding to the part types are determined, and a discharging instruction comprising the warehouse positions is sent to the AGV, so that the AGV can convey the loaded parts to the warehouse positions appointed by the discharging instruction. The positions of the part storehouses are placed according to types, so that the classified arrangement of the storehouses is facilitated.
Referring to the foregoing description of the AGV operation flow, it can be found that after the parts are transported to the designated storage location and the parts are put into storage, the parts will go to the empty container placement area, which is to return the empty containers reserved after the parts are used in production to the supplier through the logistics vehicle, so as to save the transportation cost. When the AGV carries the loaded part to the appointed storage position, the AGV can send a completion state instruction to the server, the server detects that the AGV carries the loaded part to the appointed storage position, then the AGV is triggered to execute a second carrying instruction, the AGV goes to an empty container placing area at the edge position of a production line, and empty containers are carried to a goods loading point. Alternatively, the AGV may transport one container at a time, or multiple containers.
Further, because of the large number of suppliers, particularly for automobile manufacturers, the number of parts involved is large, and therefore the containers will be distinguished from different supplier identifiers to identify the ownership of the containers. Before the AGV goes to the loading point from the empty container placing area, the AGV can also judge which suppliers the truck orders staying at the current loading point are, and select the empty container of the supplier of the current warehousing orders when selecting the empty container, namely, an RFID collecting device can be arranged in the empty container placing area at the moment, and the device can be the same as the RFID collecting device used for supplementing the part materials. And then in the process of going from the empty container placing area to the loading point through the induction door body or after the empty container is selected, the server stores the acquired and identified RFID information so as to store the RFID information into a form corresponding to the part supplier identification of the container, and the form is fed back to the corresponding part supplier according to the part supplier identification until all parts in the current warehousing order are completely detected, so that the supplier is informed of which empty containers can be returned for extraction and how much surplus stock is required in time, and the full closed-loop control based on the container RFID information is realized.
When the preset RFID information identification is performed through the induction door and the information is stored in the table, the method can comprise the following steps: when the height variation trend is reduced, acquiring a part supplier identifier corresponding to the container according to the identified preset RFID information; and storing the identified preset RFID information into a table corresponding to the part supplier identification of the container, and feeding back the table to the corresponding part supplier according to the part supplier identification when all parts in the current warehousing order are completely detected.
On the other hand, as the empty container is generated, parts of the production line are necessarily required to be supplemented, so that the preset RFID information of the empty container currently carried by the AGV can be determined through the RFID acquisition device in the process that the AGV carries the empty container from the empty container placing area to the loading point, and the type of the original parts corresponding to the empty container can be determined according to the preset RFID information; where original part type refers to the type of part that was previously specified for packaging in the empty container, and is used herein only to aid in differentiation. And generating an ex-warehouse scheduling instruction comprising the original part type so as to trigger other idle AGVs to transfer the parts corresponding to the original part type in the ex-warehouse scheduling instruction from the storage position to the used part placing area corresponding to the production line. It should be noted that other AGVs may be AGVs between the empty container placement area and the use component placement area and the storage space for the shuttle line, and the trigger scheduling may be performed by the server. The parts of the production line can be replenished in time by triggering the replenishment of the used parts after the empty containers are taken away.
