[0002] With the progress and development of the manufacturing industry, most materials need to undergo product quality inspection before leaving the factory, and the product inspection process has gradually become automated and intelligent. For example, the materials to be inspected are transported to the inspection station, the materials enter the inspection station for inspection, and exit the station through the inspection station after the inspection is completed.

[0003] In traditional solutions, a unified allocation method is usually adopted. There are multiple inspection stations in the inspection system.

[0059] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0060] The material entry and exit method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, the terminal 102 communicates with the control terminal 104 through a network. The data storage system can store data that the control terminal 104 needs to process. The data storage system can be integrated on the control terminal 104, or placed on the cloud or other network control terminals.

[0061] Specifically, when the material is at the distribution position, the staff may collect the entry status of each station, and send the entry status to the control terminal 104 through the terminal 102. The control terminal 104 reads the station number of each station from the data storage system, and controls the entry of the material according to the station number and the entry status. When the material detection is completed, the staff may push the material exit signal to the control terminal 104 through the terminal 102, and send the exit status of the next station of the current station where the material is located to the control terminal 104. The control terminal 104 controls the exit of the material according to the exit status of the next station.

[0062] Among them, the terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. Head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. The control terminal 104 can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud control terminal that provides cloud computing services.

[0063] In an exemplary embodiment, Figure 2 As shown, a material entry and exit method is provided, which is applied to Figure 1 Taking the control terminal 104 in the example as an example, the following steps are included:

[0064] S200, when the material is at the distribution position, the platform number and the entry status of each platform are obtained.

[0065] The station number is the unique identifier of each station. The station entry status reflects whether each station is currently qualified to accept materials, such as idle state and non-idle state. The allocation position is the station for caching materials. It can be the connecting station of two allocation areas, that is, the last station in the current allocation area, which can be the allocation position of the next allocation area.

[0066] Specifically, when the material is at the distribution position, it means that the material is waiting to enter the station. At this time, the control end will read the platform number and entry status of each platform, and judge the progress status of each platform. If the entry status of a platform is idle, the material entry will be controlled in combination with the platform number, for example, giving priority to entering the station through the platform with a smaller platform number.

[0067] S400 controls the entry of materials according to the station number and entry status.

[0068] Exemplarily, the control end can traverse each station to read the station number and entry status of each station. If the entry status of a station is idle, or meets other pre-set entry conditions, such as there are a small number of tasks but there are still sufficient resources to incorporate new materials, then the station can be included in the candidate entry platform.

[0069] It should be noted that there may be multiple platforms whose entry status is idle or meets the entry requirements, that is, there are multiple candidate entry platforms, which can be further screened according to other additional rules, such as controlling the materials to enter the station through the platform with a smaller platform number according to the platform number. In addition, it is also possible to control the materials to enter the station from the platform with a high priority or a short distance according to the priority order of the candidate entry platforms, the distance of the materials from each candidate entry platform, etc. After the platform for the material to enter the station is determined, the control end can send the corresponding entry instruction to the control system, so as to transfer the materials from the allocation position to the corresponding entry platform.

[0070] S600, when a material exit signal is received, obtaining the exit status of the next station of the current station where the material is located.

[0071] Among them, the material exit signal is a signal sent to the control system when the control end has detected that the material has completed security inspection or other processing operations, to indicate the control system that the material is waiting to exit. In addition, it can also be manually forced to exit the material, and the operator sends the material exit signal to the control end. For example, after the operator confirms that the material has been inspected or processed, the terminal sends the material exit signal to the control end. The exit status includes but is not limited to the empty material status, the inspection status, the discharge status, the discharge completion status, etc.

[0072] Specifically, after the material is inspected or processed, it needs to flow out of the inspection area through the main line, that is, the material will run along the outbound assembly line to the next platform until the penultimate platform of the current allocation area (because the last platform of the current allocation area is the allocation position of the next allocation area), and finally complete the outbound. Therefore, it is necessary to obtain the outbound status of the next platform of the current platform where the material is located, and control the material outbound according to the outbound status of the next platform.

[0073] S800 controls the material exit according to the exit status of the next station.

[0074] Following the above steps, after the control end receives the material exit signal, it will determine the exit status of the next platform, such as whether the next platform is idle, whether it is under maintenance, whether there are factors that hinder the material from exiting the station, etc.

[0075] For example, if the next station's outbound status is empty and the station is not in maintenance, it means that there is no material being processed on the station, and the outbound channel is unobstructed, and the material running from the current station can be received without hindrance and processed later. If the next station is in a busy state, such as the discharging state, it means that there are already materials being discharged on the station, so no new materials can be received out of the station. Therefore, the materials need to be temporarily cached at the current station, and wait until the next station's outbound status is idle before continuing to control the material outbound.

[0076] Specifically, when it is determined that the exit status of the next station is an empty material state, or meets other pre-set exit conditions, the control end will issue an exit instruction to the control system, instructing the control system (such as a conveyor belt, a handling robot, etc.) to transport the material from the current station to the next station, such as starting a conveyor belt to transport the material to the next station, or controlling a handling robot to transport the material to the next station. When it is determined that the exit status of the next station does not meet the exit conditions, such as the state of material discharge, the control end will not issue an exit instruction, the material will be cached at the current station, and the control end will continue to monitor the exit status of the next station until the exit status of the next station meets the exit conditions. The control end issues an exit instruction, so that the material can flow in an orderly manner between the stations until the material runs to the current distribution area or the second to last station on the exit assembly line, and the material exits the station.

[0077] The above-mentioned material entry and exit method, when the material is in the allocation position waiting to enter the station, controls the material entry according to the platform number and entry status of the platform, and according to the platform number and the entry status of each platform. Compared with the traditional solution that only judges whether the detection platform is idle, this solution can combine the platform number and the entry status of each platform. The platform number reflects the position of the detection platform in the entire detection system, so this solution can allocate the entry platform for the material from a global perspective, thereby improving the material entry efficiency. Furthermore, after the material detection is completed and the material exit signal is received, the material exit is also controlled based on the exit status of the next platform on the current exit assembly line. In this way, it can quickly and accurately judge whether the material can exit the station, reduce the risk of blockage of the exit assembly line, and thus improve the material entry and exit efficiency.

[0078] In one embodiment, Figure 3 As shown, obtaining the station entry status of each station includes:

[0079] S210, starting from the first platform in the current allocation area, obtaining the entry status of the platform, and judging whether the platform allows materials to enter the platform according to the entry status.

[0080] S220, when it is determined that the platform does not allow materials to enter the station, continue to obtain the entry status of the next platform until a platform that allows materials to enter the station is found for the first time, or until the entry status of the last platform in the current allocation area is obtained.

[0081] Specifically, starting from the first station in the current allocation area, determine whether each station can accept materials in the order of the station number. The entry status includes but is not limited to idle status, non-idle status, maintenance status, etc. When the platform is in an idle state, it means that the platform can accept materials and allow materials to enter the station through the platform. When it is determined that the platform does not allow materials to enter the station, the control end will not stop searching, but will continue to obtain the entry status of the next platform in the order of the platform number, and evaluate whether the next platform allows materials to enter the station until a platform that allows materials to enter the station is found, or all the platforms in the current allocation area are checked in turn, and no platform that allows materials to enter the station is found, and the entry status acquisition process is terminated at this time.

[0082] For example, if there are 5 platforms in the current allocation area, the platform numbers are Platform 1, Platform 2, Platform 3, Platform 4, and Platform 5. Platform 1 is the first platform in the current allocation area, so the entry status of Platform 1 is obtained first. If Platform 1 allows materials to enter the station, the entry status of subsequent Platforms 2, 3, etc. will not be obtained. If Platform 1 does not allow entry, the entry status of Platform 2 is obtained. If Platform 2 does not allow materials to enter the station, the entry status of Platform 3 is obtained. This cycle is repeated until a platform that allows materials to enter the station is found, or the entry status of Platforms 1 to 5 has been obtained, and the entry status acquisition process ends.

[0083] In this embodiment, by continuously searching for platforms that allow materials to enter the station, materials can accurately and efficiently find suitable entry platforms when entering the distribution area. By checking the entry status of each platform in turn, materials are prevented from blindly trying to enter unsuitable platforms, thereby reducing problems such as extended material waiting time and waste of platform resources due to platform mismatch, and improving the efficiency and rationality of material circulation in the entire distribution area.

[0084] In one embodiment, Figure 3 As shown, S400 includes:

[0085] S410, determining the platform number that allows materials to enter the station as the allocation position state value of the allocation position.

[0086] S420, comparing the station number of each station with the allocation bit status value in sequence according to the station number of each station, until a target station having the same station number and allocation bit status value is found.

[0087] S430: When the platform number of the target platform is not the maximum value among the platform numbers of the current allocation area, control the material to enter the station through the target platform.

[0088] The allocation position status value is used to characterize the status of the material at the allocation position. By assigning a special identifier such as the allocation position status value to the allocation position, the subsequent process can quickly find the platform that allows the material to enter the station according to the identifier.

[0089] Continuing with the above embodiment, when a platform that allows materials to enter the station is found in the current allocation area, the platform number of the platform is assigned to the allocation position status value of the allocation position. For example, in the current area, the first platform found that allows materials to enter the station is platform 3, and the platform number is "3", then the allocation position status value of the allocation position is assigned to "3".

[0090] Furthermore, in the order of the platform numbers of each platform, the platform numbers of each platform are compared with the allocation position status value (that is, the platform numbers of the platforms that are allowed to enter the station previously determined). This process is an orderly traversal search process. Starting from platform 1, each platform number is checked one by one to see if it is the same as the allocation position status value, until the target platform whose platform number is completely consistent with the allocation position status value is found. For example, if the allocation position status value is "3", the platform numbers of platform 1 and platform 2 are different from the allocation position status value, and the platform number of platform 3 is the same as the allocation position status value, so platform 3 is determined as the target platform.

[0091] After finding the target platform, it is necessary to determine whether the target platform is the last platform of the current allocation area. This is because in an allocation area, the last platform is used as the allocation position of the next allocation area and is not used for material entry and exit. The other platforms in the allocation area are work platforms and can be used for material entry. Therefore, only when the platform number of the target platform is not the maximum value among the platform numbers of the current allocation area, the material is controlled to enter the station through the target platform. For example, if there are 5 platforms in the current allocation area, platform 5 is the allocation position of the next allocation area, when the target platform is platform 3, the material is controlled to enter the station through platform 3. If the target platform is platform 5, the material will not enter the station through platform 5 temporarily, but it can be cached on platform 5, or the material can be moved to other allocation areas to enter the station.

[0092] It should be noted that if the allocation bit status value is less than the platform number when comparing the platform number and the allocation bit status value, it means that the system may have an error, and the control end should push a message about the abnormality of material entering and leaving the station. For example, if the allocation bit status value is "3", when compared to platform 3, theoretically, the target platform should be determined to be platform 3, but when an abnormality occurs in the entry and exit of materials, such as logical confusion in the comparison process, errors in the comparison program, etc., it may happen that when the allocation bit status value "3" is compared with the platform number of platform 3, the target platform is not identified, but the allocation bit status value "3" is continued to be compared with the platform number of platform 4. At this time, the allocation bit status value is less than the platform number, and the control end pushes a message about the abnormality of material entering and leaving the station.

[0093] In this embodiment, by allocating the bit status value and the platform number of each platform, the target platform that allows materials to enter the station can be quickly found, and when the target platform is not the last platform in the current allocation area, the material is controlled to enter the station through the target platform, so that precise control of the material entry process can be achieved, so that the material can enter the station through the appropriate platform.

[0094] In one embodiment, Figure 4 As shown, S420 includes:

[0095] S421, constructing an allocation bit state array according to the allocation bit state value, wherein the number of elements of the allocation bit state array is equal to the number of stations in the current allocation area.

[0096] S422, comparing the allocation bit state array and the station number of each station by a shift algorithm in the order of the station numbers.

[0097] Following the above embodiment, by judging the entry status of each platform, after determining a platform number that allows materials to enter the station as the allocation bit state value, the allocation bit state array is constructed according to the allocation bit state value, and the number of elements of the allocation bit state array is equal to the number of platforms in the current allocation area. For example, if there are 5 platforms in the current allocation area, the constructed allocation bit state array has 5 elements. Exemplarily, if the platform number that allows materials to enter the station is 3, the allocation bit state value is 3, and the constructed allocation bit state array is [0, 0, 0, 0, 3].

[0098] Furthermore, the 5th element of the allocation bit status array (the first one from right to left) is compared with the platform number of platform 1. If the two do not match, the 5th element of the allocation bit status array is shifted one position to the left, and the allocation bit status array becomes [0, 0, 0, 3, 0]. At this time, the 4th element of the allocation bit status array (the second one from right to left) is compared with the platform number of platform 2. If the two do not match, the 4th element of the allocation bit status array is shifted one dimension to the left, and the allocation bit status array becomes [0, 0, 3,0, 0]. The 3rd element of the allocation bit status array (the third one from right to left) is compared with the platform number of platform 3. The two are consistent, so platform 3 is taken as the target platform, and the material enters the station through platform 3.

[0099] In addition, the number of elements in the allocation position status array can also be set to be one more than the number of platforms in the current allocation area, that is, the initial allocation position status array is [0, 0, 0, 0, 0, 0]. When the material is in the allocation position, the allocation position status value is assigned to the first bit of the initial allocation position status array (from right to left), that is, [0, 0, 0, 0, 0, 3]. When it needs to be compared with the platform number of platform 1, the allocation position status value is first shifted left by one position, and the allocation position status array becomes [0, 0, 0, 0, 3, 0]. Then, the same method as above is used to find platform 3 as the target platform.

[0100] In this embodiment, by constructing an allocation bit state array and applying a shift algorithm, the station number and the allocation bit state value can be compared more carefully and accurately, thereby quickly and accurately finding the target station that allows materials to enter the station.

[0101] In one embodiment, Figure 4 As shown, the method also includes:

[0102] S440 , when the station number of the target station is the maximum value of the station numbers of the current allocation area, the material is cached to the target station, and the target station is determined as the allocation position of the next allocation area.

[0103] Continuing with the above embodiment, when the platform number of the target platform is the maximum value of the platform number of the current allocation area, the control end sends a corresponding control instruction to the control system to cache the material to the target platform, which means that the material will not be controlled to enter the station through the target platform at this time, and the target platform will be determined as the allocation position of the next allocation area.

[0104] For example, if the shift algorithm in the above embodiment is used to analyze and determine that the target platform is platform 5, and there are only 5 platforms in the current allocation area, then platform 5 is the last platform in the current allocation area. The material does not enter the station through platform 5, but is temporarily cached on platform 5. Platform 5 is used as the allocation position for the next allocation area. In the next allocation area, the same method as in the above embodiment is used to control the material entry.

[0105] In this embodiment, when only the last platform in the current allocation area allows materials to enter the station, the materials do not enter the station directly through the platform, but are cached at the platform, and the platform is used as the allocation position for the next platform. In this way, coordination between multiple allocation areas can be achieved. Compared with allocating materials to multiple platforms through only one allocation position, the above scheme can reduce the pressure of material allocation and improve the efficiency of material entry and exit.

[0106] In one embodiment, Figure 4 As shown, the method also includes:

[0107] S450: When it is determined that all platforms in the current allocation area do not allow materials to enter the station, control the materials to enter the station through platforms in other allocation areas other than the current allocation area.

[0108] Continuing with the above embodiment, according to the platform number, the entry status of the platforms in the current allocation area is obtained in sequence starting from the first platform, and whether the platform allows materials to enter the station is determined according to the entry status. If the platforms in the current allocation area do not allow materials to enter the station, for example, all platforms are in a non-idle state, this means that the current allocation area is no longer suitable for material entry. The control end can send a material transfer instruction to the control system (such as a conveyor belt or a handling robot) to transfer the materials to other allocation areas and enter the station through the platforms in other allocation areas.

[0109] For example, an additional temporary storage area can be set up. If the last station in the current distribution area does not allow materials to enter the station, the materials are first transferred to the temporary storage area for storage, and the station entry status of the stations in other distribution areas is continuously detected. Once a station changes to a state that allows materials to enter the station, the materials are transferred from the temporary storage area to the distribution area where the station is located. In addition, the station status of the adjacent distribution area can be checked first to determine whether the adjacent distribution area can receive materials.

[0110] In this embodiment, by setting up a material cache and entering the station through other allocation areas, it is possible to better cope with emergencies such as busy platforms or failures. Even if the platforms in the current allocation area do not allow materials to enter the station, the materials will not continue to stagnate on the transportation line, thereby improving the flexibility and adaptability of materials entering and leaving the station.

[0111] In one embodiment, Figure 5 As shown, before S800, it also includes:

[0112] S700, update the outbound status of the current station where the material is located to the outbound status.

[0113] S800 includes:

[0114] S810, when the outbound status of the next platform is an empty material status or an inspection status, control the current platform to release the material so that the material moves to the next platform, and update the outbound status of the current platform to an outbound completion status.

[0115] S820, determining whether the current station is the second to last station in the current allocation area, if not, returning to S700.

[0116] S830, if yes, control the material to exit the station through the second to last station.

[0117] It should be noted that, in this embodiment, materials need to leave the station along the exit assembly line. In this embodiment, if the platform where the material is located is platform 2, then when the material leaves the station, it needs to run to platform 3, platform 4, etc. in sequence until it reaches the position that allows the material to leave the exit assembly line.

[0118] Continuing with the above embodiment, when a material exit signal is received, the material needs to run from the detection position or the processing position to the platform, for example, by conveying the material from the detection position to the platform through a conveyor belt. In this process, the exit status of the current platform where the material is located is updated to the discharge status. When the platform is in the discharge status, it means that the material being discharged on the platform has been detected or processed, and other materials are temporarily not allowed to be placed on the platform.

[0119] Furthermore, the control end obtains the exit status of the next platform and determines whether the next platform allows the placement of materials. Specifically, if the exit status of the next platform is an empty material state or an in-check state, that is, the next platform allows the placement of materials (the in-check state means that there are materials in the detection position associated with the platform, but there are no materials on the platform surface), then the control end controls platform 1 to release the materials, allowing the materials to run to the next platform, and updates the exit status of the current platform to the exit completion status. It can also update the entry status of the current platform to an empty material platform within a preset time after the current platform is in the exit completion status, waiting for the next material to enter the station. If the position of the next platform is in the exit status or the exit completion status, it means that the material cannot run to the next platform temporarily, and can be temporarily cached on the current platform, and the exit status of the next platform is continuously detected.

[0120] After the material runs to the next platform, the "next platform" becomes the current platform, and the process returns to the step of updating the outbound status of the current platform to the outbound platform, and continues to determine whether the next platform of the current platform allows the current platform to release materials, until the current platform is the second to last platform of the current allocation area. This is because the last platform of the current allocation area is the allocation position of the next allocation area, and materials do not enter or exit the station through this platform.

[0121] Exemplarily, an exit status value can be assigned to the exit status of a platform. For example, the exit status value corresponding to a platform in an empty material state is 0, the exit status value corresponding to a platform in an under-inspection state is 88, the exit status value corresponding to a platform in a discharging material state is 99, and the exit status value corresponding to a platform in an exit completion state is 100. The above-mentioned updating of the platform's exit status actually updates the platform's exit status value.

[0122] In this embodiment, the material outbound process is divided into multiple stages through a series of operations such as the outbound status determination and outbound status update of the platform, so that the status of each platform can be accurately controlled and the material outbound can be precisely controlled. In addition, since the material inbound and material outbound use two different sets of logic, they will not interfere with each other, which can improve the efficiency of material inbound and outbound.

[0123] In one embodiment, Figure 6 As shown, the method also includes:

[0124] S900, receiving the inbound and outbound scheduling instructions from the client, the inbound and outbound scheduling instructions carrying the material inbound and outbound parameters, and controlling the material inbound and outbound according to the material inbound and outbound parameters.

[0125] Among them, the material entry and exit parameters include but are not limited to the target platform number, material identification, material type, quantity, entry and exit speed, entry and exit time and other information.

[0126] Specifically, in addition to the above-mentioned automated station allocation method of the control end, the operator can also control the entry and exit of materials through the client connected to the control end. For example, the client can provide a user-friendly user interface, such as directly presenting the area map of the station on the client screen, so that the user can quickly find the station to be operated, and input the material entry and exit parameters through touch operation, and send the entry and exit scheduling instructions to the control end. After receiving the entry and exit scheduling instructions sent by the client, the control end controls the entry of materials according to the material entry and exit parameters.

[0127] In this embodiment, the user can manually control the entry and exit of materials through the client, which can make the material entry and exit process more flexible and applicable. The control end receives the entry and exit scheduling instructions from the client and controls the entry and exit of materials based on the material entry and exit parameters carried therein. It can achieve accurate and orderly control of the flow of materials between various platforms, so that it can better adapt to the needs of different actual application scenarios such as production and logistics.

[0128] In order to make a clearer description of the material entry and exit method provided by this application, the following is combined with the attached Figure 7 A detailed embodiment is explained, and the detailed embodiment includes:

[0129] S210, starting from the first platform in the current allocation area, obtaining the entry status of the platform, and judging whether the platform allows materials to enter the platform according to the entry status.

[0130] S220, when it is determined that the platform does not allow materials to enter the station, continue to obtain the entry status of the next platform until a platform that allows materials to enter the station is found for the first time, or until the entry status of the last platform in the current allocation area is obtained.

[0131] S410, determining the platform number that allows materials to enter the station as the allocation position state value of the allocation position.

[0132] S421, constructing an allocation bit state array according to the allocation bit state value, wherein the number of elements of the allocation bit state array is equal to the number of stations in the current allocation area.

[0133] S422, comparing the allocation bit state array and the station number of each station by a shift algorithm in the order of the station numbers.

[0134] S430: When the platform number of the target platform is not the maximum value among the platform numbers of the current allocation area, control the material to enter the station through the target platform.

[0135] S440 , when the station number of the target station is the maximum value of the station numbers of the current allocation area, the material is cached to the target station, and the target station is determined as the allocation position of the next allocation area.

[0136] S450: When it is determined that all platforms in the current allocation area do not allow materials to enter the station, control the materials to enter the station through platforms in other allocation areas other than the current allocation area.

[0137] S700, update the outbound status of the current station where the material is located to the outbound status.

[0138] S810, when the outbound status of the next platform is an empty material status or an inspection status, control the current platform to release the material so that the material moves to the next platform, and update the outbound status of the current platform to an outbound completion status.

[0139] S820, determining whether the current station is the second to last station in the current allocation area, if not, returning to S700.

[0140] S830, if yes, control the material to exit the station through the second to last station.

The task scheduling module 840 can formulate material entry and exit scheduling strategies based on the intelligent allocation results, that is, the final entry and exit platforms of the materials, so as to adjust the entry and exit platforms of the materials in real time to deal with emergencies. The data analysis module 850 can store and analyze the entry and exit platforms of the materials, and the obtained material entry and exit analysis results can provide a reliable basis for subsequent material entry and exit optimization, material entry and exit control system optimization, etc.
