Description

Technical Field

[0001] The present invention relates to the field of material handling, in particular to a method for a crane to work across buildings, a method and system for controlling a crane to work across buildings, and a system for handling materials across buildings. Background Art

[0002] Fab is the abbreviation of semiconductor manufacturing plant. Large Fab plants will include multiple buildings, and each building will use OHT (Overhead Hoist Transport, overhead crane system) to carry material boxes, so as to realize the movement of semiconductor devices in different areas of the building. At the same time, in order to realize the movement of material boxes between different buildings, as shown in the patent document with application publication number US2006 / 0201375A1, in the prior art, the overhead crane tracks in the OHT between different buildings are connected by bridge tracks, and the overhead crane is moved between different buildings to realize the transfer of material boxes or overhead cranes between different buildings.

[0003] However, in actual factory construction or factory expansion, the networks, TCS (Transport Control System), and maps of different buildings are different. Therefore, when the overhead crane needs to be transferred from one building to another, the data of the overhead crane needs to be switched before it can work effectively in another building.

[0004] Usually, the overhead crane will perform data switching at the predetermined position of Building 1 or Building 2 or at the bridge track, which requires the overhead crane to occupy the bridge track for a certain period of time. When the data switching of the overhead crane at the bridge track fails, manual intervention is required to process it, which causes the overhead crane to occupy the bridge track for a longer time, hindering other overhead cranes from operating across buildings. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems existing in the prior art and to provide a method for a crane to work across buildings, a method and system for controlling the crane to work across buildings, and a system for transporting materials across buildings.

[0006] The purpose of the present invention is achieved through the following technical solutions: The method for working a crane across a building includes the following steps: The TCS of the initial building sends a forwarding request to the TCS of the target building according to the forwarding instruction of the MCS; The TCS of the target building sends a forwardable response to the TCS of the initial building; The TCS of the initial building sends an execution instruction to the transfer crane that executes the transfer request so that the transfer crane moves to the relay point configured for the initial building at the closed section of the bridge track; When the transfer crane first moves to the data switching point located upstream of the relay point configured for the initial building at the closed section, data switching begins; When the transfer crane moves to the switching confirmation point configured for the initial building at the closed section, it determines whether its data switching is completed; if so, the transfer crane moves to the relay point to wait for the control instruction of the TCS of the target building; if not, the transfer crane moves to the manual intervention track configured for the initial building connected to the closed section; the switching confirmation point is located between the relay point and the data switching point and is close to the relay point; When the transfer crane moves to the reconfirmation point configured for the initial building at the closed section, it confirms whether the data switching is completed; the reconfirmation point is located upstream of the entry point of the manual intervention track and downstream of the relay point; if so, the transfer crane loops back to the relay point configured for the initial building at the closed section to wait for the control instruction of the TCS of the target building; if not, the transfer crane enters the manual intervention track to wait for manual intervention.

[0007] Preferably, a plurality of bridge tracks are arranged between the initial building and the target building, and when a transfer instruction needs to be executed, the TCS of the initial building selects one of the plurality of bridge tracks according to a predetermined principle to implement the transfer instruction.

[0008] Preferably, when the transfer instruction only requires the transfer of the overhead crane, the TCS of the initial building selects the bridge track for implementing the transfer instruction according to the load rate of each bridge track; And / or, the TCS of the initial construction selects the bridge track for implementing the transfer instruction according to the distance from the idle overhead travelling vehicle closest to the relay point of each bridge track to the corresponding relay point and / or the estimated time to the corresponding relay point.

[0009] Preferably, after a bridge track is selected according to the load rate, the TCS of the initial building selects an idle overhead crane closest to the relay point configured for the initial building in the selected bridge track as the transfer overhead crane.

[0010] Preferably, when the transfer instruction requires material handling, the TCS of the initial construction selects the bridge rails in order from near to far according to the load rate of each bridge rail and the distance of each bridge rail from the material.

[0011] Preferably, when selecting the bridge track, the TCS of the initial building determines whether to select the bridge track according to the number of overhead cranes in each bridge track and / or the number of overhead cranes at the artificial intervention track configured for the initial building in each bridge track.

[0012] Preferably, before the transfer crane enters the manual intervention track configured for the initial building, it determines with the TCS of the initial building or the TCS of the target building whether it can enter the manual intervention track configured for the initial building.

[0013] Preferably, when receiving the transfer instruction, the TCS of the target building determines whether the number of overhead cranes in the target building has reached the maximum number of overhead cranes. If so, the TCS of the target building sends a transfer request to the TCS of a selected building based on the number of overhead cranes of other buildings connected to the target building, and the number of overhead cranes of the selected building is less than the maximum number of overhead cranes set for the selected building.

[0014] The control method of overhead crane across building work includes the following processes: S01, receiving an execution instruction sent by the TCS of the initial building and controlling the travel motor to start so that the transfer crane moves to the relay point configured for the initial building at the closed section of the bridge track; S02, when it is determined that the transfer crane moves to the closed section as the data switching point of the initial building configuration, data switching begins; S03, when determining the transfer crane moves to the closed section for the initial construction configuration switching confirmation point, determine whether the data switching is complete, and if so, execute S04, if not, execute S05; S04, controlling the travel motor to move the transfer crane to the relay point to wait for the control instruction of the TCS of the target building; S05, controlling the travel motor to move the transfer crane toward the artificial intervention track configured for the initial building connected to the closed section and executing S06; the switching confirmation point is located between the relay point and the data switching point and is close to the relay point; S06, when it is determined that the transfer crane moves to the closed section as the reconfirmation point of the initial building configuration, confirm whether the data switching is completed, if so, execute S07, if not, execute S08; the reconfirmation point is located upstream of the entry point of the manual intervention track and downstream of the relay point; S07, controlling the travel motor to make the transfer crane cycle back to the relay point configured for the initial building at the closed section to wait for the control instruction of the TCS of the target building; S08, controlling the travel motor to make the transfer crane enter the manual intervention track to wait for manual intervention.

[0015] Overhead crane cross-building work control system, including: A receiving instruction start unit, used for receiving an execution instruction sent by the TCS of the initial building and controlling the start of the travel motor to move the transfer crane to a relay point configured for the initial building at the closed section of the bridge track; A data switching unit, used to start data switching when it is determined that the transfer crane moves to the closed section where the data switching point of the initial building configuration is located; A data switching confirmation unit, used to determine whether the data switching is completed when it is determined that the transfer crane moves to the closed section as the switching confirmation point of the initial building configuration, and if so, communicate with the transfer relay point unit, if not, communicate with the cyclic movement control unit; A transfer relay point unit, used to control the travel motor to move the transfer crane to the relay point to wait for the control instruction of the TCS of the target building; A cyclic movement control unit is used to control the travel motor to move the transfer crane to the artificial intervention track configured for the initial building connected to the closed section and communicate with the reconfirmation unit; the switching confirmation point is located between the relay point and the data switching point and is close to the relay point; A reconfirmation unit is used to confirm whether the data switching is completed when it is determined that the transfer crane moves to the closed section as the reconfirmation point of the initial building configuration, and if so, communicate with the return relay point unit; if not, communicate with the intervention control unit; the reconfirmation point is located upstream of the entry point of the artificial intervention track and downstream of the relay point; A return relay point unit is used to control the travel motor to make the transfer crane cycle back to the relay point configured for the initial building at the closed section to wait for the control instruction of the TCS of the target building; The intervention control unit is used to control the travel motor to make the transfer crane enter the manual intervention track to wait for manual intervention.

[0016] A cross-building material handling system, comprising an overhead crane system arranged in at least two buildings, wherein the overhead crane tracks of the two overhead crane systems are connected by a bridge track, wherein a closed section of the bridge track is connected with two manual intervention tracks, wherein one manual intervention track is configured for use by an overhead crane transferring in a first direction, and the other manual intervention track is configured for use by an overhead crane transferring in a second direction, wherein the second direction is opposite to the first direction; Two site groups are arranged at the closed section, one site group is used for the overhead travelling vehicle transferring in the first direction, and the other site group is used for the overhead travelling vehicle transferring in the second direction; Each site group includes a data switching point, a switching confirmation point, a relay point and a reconfirmation point which are set in sequence; The overhead travelling vehicle transferring in the first direction and the overhead travelling vehicle transferring in the second direction start data switching when they move to the data switching points in the site groups configured for them respectively; The overhead crane transferring to the first direction and the overhead crane transferring to the second direction confirm whether the data switching is completed when they move to the switching confirmation point in the site group configured for them respectively to determine whether to wait for the control instruction of the TCS of the building to be transferred to at the relay point in the site group configured for them respectively or move to the re-confirmation point; The overhead travelling vehicle transferring in the first direction and the overhead travelling vehicle transferring in the second direction confirm whether data switching is completed when they move to the reconfirmation points in the site groups configured for them respectively to determine whether to stop at the manual intervention tracks configured for them respectively or to move cyclically to the relay points in the site groups configured for them respectively.

[0017] The advantages of the technical solution of the present invention are mainly reflected in: The present invention sets a bridge channel with a closed section between two buildings, and at the same time connects the bridge channel to the manual intervention track matching each building, and sets a site group matching each building in the closed section, so that the overhead crane that executes the transfer request starts data switching and determines whether the data switching is completed at different sites, and controls the overhead crane to move to the relay point of the closed section or the manual intervention track according to the completion of the data switching. After the overhead crane completes the data switching, it can enter the target building as soon as possible under the control of the TCS of the target building. At the same time, when the data switching of the overhead crane is abnormal, it enters the manual intervention track for manual intervention. During data switching and manual intervention, it will not interfere with other overhead cranes in executing the transfer request, which is conducive to efficient cross-building operation of the overhead crane.

[0018] The present invention arranges a plurality of bridging tracks between two buildings, which can effectively increase the channels for cross-building operations, can meet the needs of more frequent cross-building transportation, and increase the redundancy of the transportation system.

[0019] The present invention can fully utilize the buffer tracks of each bridge track through a special bridge track balancing principle, thereby improving the efficiency of cross-building operations.

[0020] When transporting a crane from an initial building to a target building, the present invention further determines the number of cranes in the target building, and regulates the number of cranes in the target building to avoid an increase in congestion rate in the target building due to an excessive number of cranes in the target building, and can achieve crane balance between buildings, thereby improving the utilization rate of the cranes.

[0025] Specifically, the number of the buildings can be set to multiple as needed. For the convenience of description, this embodiment takes two buildings as an example for description. Figure 1 As shown, two buildings are defined as Building 1 100 and Building 2 200, and overhead crane systems are respectively provided in Building 1 100 and Building 2 200. The overhead crane systems, like the prior art, include overhead crane tracks 300 arranged according to the positions of processing equipment and / or buffer equipment and an overhead crane that can move on the overhead crane tracks 300. Their specific structures are known technologies and are not described in detail here. TCSs for controlling the movement of the overhead cranes therein are respectively provided in Building 1 100 and Building 2 200, and the two TCSs can be connected to a MCS (Material Control System) together. Of course, each TCS can also be connected to an independent MCS, and the MCS communicates with the MES (Manufacturing Execution System). At the same time, the two TCSs can communicate with each other through known communication methods to achieve data sharing between the two parties.

[0026] The overhead crane tracks 300 of the building 100 and the building 200 are connected by at least one bridge track 400. In this embodiment, one bridge track 400 is taken as an example. The bridge track 400 includes a first main track 410, a second main track 420, a first turning track 430, and a second turning track 440. The first main track 410 is used for the overhead crane to move from the building 100 to the building 200, and the second main track 420 is used for the overhead crane to move from the building 200 to the building 100. The overhead crane moving from the building 100 to the building 200 is defined as the overhead crane transferred to the first direction, and the overhead crane moving from the building 200 to the building 100 is defined as the overhead crane transferred to the second direction. The first turning track 430 is close to the building 100 and is used for the overhead crane to move from the second main track to the first main track. The second turning track 440 is close to the building 200 and is used for the overhead crane to move from the first main track to the second main track.

[0027] The specific shapes of the first main rail 410, the second main rail 420, the first turning rail 430 and the second turning rail 440 can be designed as needed. For example, the first main rail 410 and the second main rail 420 are two parallel straight rails. Preferably, the first main rail 410 and the second main rail 420 include a straight rail and a 90° turning rail connected at both ends of the straight rail, so that the first main rail 410 and the second main rail 420 are C-shaped and they are arranged in mirror symmetry, the first turning rail 430 and the second turning rail 440 are C-shaped rails, and the straight rails of the first main rail 410 and the second main rail 420 and the first turning rail 430 and the second turning rail 440 form the waist-shaped closed section.

[0028] The artificial intervention track configured for the building 100 is defined as the first artificial intervention track 450, and the artificial intervention track configured for the building 200 is defined as the second artificial intervention track 460. The first artificial intervention track 450 and the second artificial intervention track 460 are C-shaped, and at least one parking point 456 is respectively provided at the first artificial intervention track and the second artificial intervention track. The number and position of the first artificial intervention track 450 and the second artificial intervention track can be designed according to needs. For example, the first artificial intervention track can be connected to the straight rail of the second main rail 420 and / or the side of the second turning rail 440, and the second artificial intervention rail is connected to the straight rail of the first main rail 410 and / or the side of the first turning rail 430.

[0029] The site group used by the overhead travelling vehicle for transfer in the first direction is the site group configured for the building 100, and is defined as the data switching point, switching confirmation point, relay point and reconfirmation point configured for the building 100, which are the first data switching point 470, the first switching confirmation point 480, the first relay point 490 and the first reconfirmation point 401. The first data switching point 470, the first switching confirmation point 480 and the first relay point 490 are sequentially arranged on the straight track of the first main track 410, and the first data switching point 470 is close to the building 100, and the first relay point 490 is close to the building 200. The first reconfirmation point 401 is arranged on the straight track of the second main track 420 and / or on the second turning track 440, and the first reconfirmation point 401 is located upstream of the entrance end of the first manual intervention track 450 connected to the track where it is located.

[0030] The site group used by the overhead travelling vehicle for transfer in the second direction is the site group configured for the building 2 200, and the data switching point, switching confirmation point, relay point and reconfirmation point configured for the building 2 200 are defined as the second data switching point 402, the second switching confirmation point 403, the second relay point 404 and the second reconfirmation point 405. The second data switching point 402, the second switching confirmation point 403 and the second relay point 404 are sequentially arranged on the straight track of the second main track 420, and the second data switching point 402 is close to the building 2 200, and the second relay point 404 is close to the building 1 100. The second reconfirmation point 405 is arranged on the straight track of the first main track 410 and / or on the first turning track 430, and the second reconfirmation point 405 is located upstream of the entrance end of the second manual intervention track 460 connected to the track where it is located.

[0031] Position identifiers for the overhead travelling crane to determine the positions of each point are respectively provided at the first data switching point 470, the first switching confirmation point 480, the first relay point 490, the first reconfirmation point 401, the second data switching point 402, the second switching confirmation point 403, the second relay point 404 and the second reconfirmation point 405. The position identifiers may be, for example, electronic tags (RFID tags, NFC tags) or bar codes or QR codes, etc. Correspondingly, a reader for reading the position identifiers may be provided on the overhead travelling crane.

[0032] As attached Figure 2 , Attachment Figure 3 As shown, the following takes Building 100 as the initial building, Building 200 as the target building, and there is only one bridge track 400 between them as an example to illustrate the overhead crane cross-building working method. At this time, it includes the following steps: When MCS receives the instruction from MES and determines that a material of building 100 needs to be transferred to building 200 or a crane needs to be transferred from building 100 to building 200, it sends a transfer instruction to the TCS of building 100. When the TCS of building 100 receives the transfer instruction, it can first determine the transfer crane that executes the transfer instruction, and then send a transfer request to the TCS of building 200. At this time, the transfer request includes the information of the transfer crane that needs to execute the transfer instruction. Of course, in other embodiments, the TCS of building 100 can also determine the transfer crane that executes the transfer instruction and send the information of the transfer crane to the TCS of building 2 200 after receiving the response sent by the TCS of building 2 200 that the transfer can be made.

[0033] After receiving the forwarding request, the TCS of the building 2 200 sends a forwarding response to the TCS of the building 1 100 .

[0034] The TCS of the building 100 sends an execution instruction to the transfer crane that executes the transfer request to enable the transfer crane to move to the first relay point 490 configured for the building 100 at the closed section of the bridge track 400 .

[0035] After receiving the execution instruction, if it is determined that the execution instruction only needs to be transferred to the second building 200, the transfer crane starts and moves directly to the first main rail 410 according to the planned path and moves to the first relay point 490 on the first main rail 410. If it is determined that the execution instruction is to transfer the materials in the first building 100 to the second building 200, the transfer crane first goes to the location of the materials according to the planned path to grab the materials and then moves to the first main rail 410 and moves to the first relay point 490.

[0036] When the transfer crane moves toward the first relay point on the first main rail 410, it determines whether it has moved to the first data switching point 470. If it is determined that it has moved to the first data switching point 470, the transfer crane starts data switching, and the data switching includes switching of operating data such as map data and teaching data, switching of wireless network points, and establishing a connection with the TCS of building two 200.

[0037] Specifically, the transfer crane stores compressed files including map data, teaching data and other operating data corresponding to each building. When it is determined to be transferred to building 2 200, the transfer crane finds the compressed file corresponding to building 2 200 from the compressed files stored therein according to the number of building 2 200 or other identification information of building 2 200, decompresses and switches the corresponding operating data. After the switching of the operating data is completed, if the transfer crane has established a connection with the TCS of building 2 200 at this time, the transfer crane feeds back a message of completing the data switching to the TCS of building 2 200. Otherwise, after determining to establish a connection with the TCS of building 2 200, the transfer crane feeds back a message of completing the data switching to the TCS of building 2 200. After receiving the message of completing the data switching from the transfer crane, the TCS of building 2 200 can feed back a message of completing the data switching from the transfer crane to the TCS of building 1 100. Correspondingly, the TCS of building 1 100 can release the control of the transfer crane.

[0038] The switching of the wireless network point and the establishment of a connection with the TCS of Building 2 200 are implemented, for example, according to the following process: the transferring crane switches its IP to the network segment of the TCS of Building 2 200, and communicates with the TCS of Building 2 200 via UDP unicast; the transferring crane sends a control request to the TCS of Building 2 200; the TCS of Building 2 200 includes the crane in the control scope according to the control request of the crane and feeds back the information of including the crane in the control scope to the transferring crane; when the transferring crane receives the information of including the crane in its control scope from the TCS of Building 2 200, it determines whether the switching of its operating data is completed; if completed, it feeds back the message of data switching completion to the TCS of Building 2 200. The technology for the TCS of the building 2 200 to bring the overhead crane into the control scope is a known technology. For example, the TCS of the building 2 200 has a control overhead crane table. When a new overhead crane requests its control, the TCS of the building 2 200 adds the information of the overhead crane requested to be controlled to the control overhead crane table, that is, brings the overhead crane into its control scope. Subsequently, the overhead crane can be controlled according to the information in the control overhead crane table. The TCS of the building 2 200 feeds back the information that the overhead crane has been brought into its control scope to the MCS and / or the TCS of the building 1 100.

[0039] The transfer crane can simultaneously switch the operation data and the wireless network point and establish a connection with the TCS of the second building 200. Moreover, before the operation data is switched, if the transfer crane establishes a connection with the TCS of the second building 200, after the operation data is switched, the transfer crane confirms the completion of the data switching and feeds back the information of the completion of the data switching to the TCS of the second building 200; if the transfer crane establishes a connection with the TCS of the second building 200 of the second building after the operation data is switched, after the connection is established, the transfer crane confirms the completion of the data switching and feeds back the information of the completion of the data switching to the TCS of the second building 200.

[0040] The transfer crane confirms whether it has moved to the first switching confirmation point 480 during the movement process. If it is confirmed that it has moved to the first switching confirmation point 480, the transfer crane determines whether its data switching is completed; if so, that is, the transfer crane determines that the data switching is completed, the transfer crane continues to move along the first main rail 410 to the first relay point 490 and waits for the control instruction of the TCS of the building 2 200.

[0041] At this time, the TCS of Building 200 will immediately send a control instruction to the transfer crane at the first relay point 490. If the transfer crane executes a transfer instruction to transport materials to a certain location in Building 200, the control instruction sent by the TCS of Building 200 to the transfer crane controls the transfer crane to move to the location to which the materials are to be transported according to the planned path, and then moves the transfer crane to the standby area to wait for being called.

[0042] If the transfer crane executes a transfer instruction to dispatch the crane to work in Building 2 200, when the TCS of Building 2 200 determines that there is no current transport task (i.e., transporting materials from one position of Building 2 200 to another position of Building 2 200), the transfer crane can be controlled to move to the standby area at the crane track 300 of Building 2 200 to wait for call. When the TCS of Building 2 200 determines that there is currently a transport task and the transfer crane is closest to the initial point of the transport task, the TCS of Building 2 200 controls the transfer crane to execute the transport task, and after the transfer crane completes the transport task, the transfer crane moves to the standby area to wait for call.

[0043] If not, that is, the transfer crane determines that it has not completed the data switching, the transfer crane moves along the second turn rail 440 to the second main rail 420 and moves toward the direction of building 100.

[0044] During the movement of the transfer crane along the second main rail 420, it is determined whether it moves to the first reconfirmation point 401. If it is determined that the transfer crane moves to the first reconfirmation point 401, the transfer crane reconfirms whether its data switching is completed; if so, the transfer crane loops back to the first relay point 490 along the second main rail, the first turning rail, and the first main rail to wait for the control instruction of the TCS of the building 2 200. If not, the transfer crane enters the first manual intervention track to wait for manual intervention. The specific operation of manual intervention is not the focus of the present invention and is not described here. In addition, during manual intervention, if it is determined that the transfer crane cannot establish a connection with the TCS of the building 2, the TCS of the building 1 communicates with the TCS of the building 2 to determine whether the TCS of the building 2 is down and handle it. After completing the manual intervention, the transfer crane completes the data switching and feeds back the information of the completion of the data switching to the TCS of the building 2. At the same time, the transfer crane loops back to the first relay point 490 from the first manual intervention track to wait for the control instruction of the TCS of the building 2 200.

[0045] Furthermore, after the TCS of building one 100 issues the forwarding request, if it is determined that the TCS response of building two 200 is abnormal, corresponding abnormal control is performed. The response abnormality is, for example, a timeout of the TCS response of building two 200, or an abnormal response status of the TCS of building two 200, or a confirmation that the TCS of building two 200 is down (the TCS of building one 100 can determine whether the TCS of building two 200 is down by sending a heartbeat packet to the TCS of building two 200), etc.

[0046] If the TCS of the building 100 has not yet determined the transfer crane to execute the transfer request, the TCS of the building 100 suspends determining the transfer crane and suspends executing the transfer instruction; if the TCS of the building 100 has determined the transfer crane to execute the transfer request, the TCS of the building 100 suspends scheduling the transfer crane or schedules the transfer crane to a designated location to wait for subsequent scheduling, or the TCS of the building 100 controls the transfer crane to grab materials and then moves to a designated location to wait for subsequent scheduling.

[0047] Of course, if the TCS of Building One determines that an abnormality occurs in the TCS of Building Two after the transfer crane enters the bridge track and before moving to the first data switching point, the TCS of Building One can control the transfer crane to move in a circle in the closed section or directly return to the standby point in the area of ​​Building One or perform the transport task in Building One or directly enter the first manual intervention track to wait for manual intervention.

[0048] Furthermore, if multiple bridge tracks are set between the building 100 (initial building) and the building 200 (target building), when a transfer is required, the TCS of the building 100 will select one of the multiple bridge tracks to implement the transfer instruction according to a predetermined principle. At the same time, the TCS of the building 100 will feedback the information of the bridge track 400 selected to implement the transfer instruction to the TCS of the building 200. Therefore, the TCS of the building 200 can accurately know the bridge track 400 where the transfer overhead crane is located to perform corresponding control.

[0049] In the first embodiment, if the transfer instruction only requires the transfer of the overhead crane but does not require the transportation of materials, the TCS of the building 100 selects the bridge rail 400 for implementing the transfer instruction according to the load rate of each bridge rail 400. In addition, according to the position of the first relay point configured for the building 1 on the selected bridge rail 400, the nearest idle overhead crane is selected as the transfer overhead crane.

[0050] For example, there are three bridge tracks between Building 100 and Building 200. The first bridge track allows 4 overhead cranes to be located on it at the same time, the second bridge track allows 5 overhead cranes to be located on it at the same time, and the third bridge track allows 6 overhead cranes to be located on it at the same time. When the TCS of Building 1 and the TCS of Building 2 determine that there are 2 overhead cranes on the first bridge track, the second bridge track 400 and the third bridge track 400 respectively, the load rate of the first bridge track is 2 / 4=0.5, the load rate of the second bridge track is 2 / 5=0.4, and the load rate of the third bridge track is 2 / 6=0.33. The third bridge track has the lowest load rate. At this time, the TCS of Building 100 determines that the third bridge track is used to implement the transfer instruction currently received by it, and at the same time, the TCS of Building 100 determines that the idle overhead crane closest to the third bridge track in Building 100 executes the transfer instruction. The TCS of Building 1 and the TCS of Building 2 can determine how many transfer cranes are on each bridge track at the same time according to the number of transfer cranes moved to the bridge track and the number of transfer cranes moved out to the bridge track.

[0051] Of course, in the second embodiment, if only the transfer of the overhead crane is required, the TCS of the building 100 selects the bridging track 400 for implementing the transfer instruction based on the distance from the idle overhead crane closest to the relay point of each bridging track 400 to the corresponding relay point and / or the estimated time to the corresponding relay point.

[0052] For example, the distance from the idle overhead travelling car closest to the first relay point 490 on the first bridge track in building 100 to the first relay point 490 on the first bridge track is 10 meters, the distance from the idle overhead travelling car closest to the first relay point 490 on the second bridge track in building 100 to the first relay point 490 on the second bridge track is 15 meters, and the distance from the idle overhead travelling car closest to the first relay point 490 on the third bridge track in building 100 to the first relay point 490 on the first bridge track is 20 meters. Then, the TCS of building 100 selects the first bridge track for implementing the transfer instruction, and at the same time selects the idle overhead travelling car closest to the first relay point 490 on the first bridge track and executes the transfer instruction.

[0053] Furthermore, the TCS of the building 100 may first select the bridge rail 400 according to the load rate. If the load rates at the bridge rails 400 are the same, the bridge rail 400 may be further selected according to the second embodiment.

[0054] Of course, if the transfer instruction requires the transportation of materials, the TCS of the initial construction can select bridge tracks according to the load rate of each bridge track and the distance of each bridge track from the material in the order from near to far. For example, when the load rate of the bridge track closest to the material does not meet the requirements, if the load rate of the bridge track second closest to the material meets the requirements, the bridge track second closest to the material is selected to achieve the transportation, and the idle overhead crane closest to the material is selected as the transfer overhead crane. When judging whether the load rate meets the requirements, the load rate can be compared with the set threshold. If the set threshold is reached, it is considered that it does not meet the requirements, otherwise it is considered that it meets the requirements. The set threshold can be designed as needed, for example, selected between 0.75-1.

[0055] Further, when selecting the bridge track 400, the TCS of the building 100 determines whether to select the bridge track 400 according to the number of overhead cranes at the first manual intervention track 450 matched for the building 100 in each bridge track 400. If it is determined that the number of overhead cranes at the first manual intervention track 450 in a bridge track 400 exceeds the warning value, the bridge track 400 is not selected for the transfer. For example, the warning value of the number of overhead cranes that can be parked at each first manual intervention track 450 is 3. When there are three transfer overhead cranes at a first manual intervention track 450, that is, the number of overhead cranes reaches the warning value, the bridge track 400 is not selected. The warning value is less than the maximum value of the transfer overhead cranes that can be parked on the manual intervention track. The TCS of the building 1 can determine the number of overhead cranes at each first manual intervention track according to the number of transfer overhead cranes that inquire whether they can enter a first manual intervention track and the number of transfer overhead cranes that have completed manual intervention at the first manual intervention track. Of course, when selecting the bridge track 400, the TCS of the building 100 can also be selected according to the number of overhead cranes on the bridge track 400. For example, the number of overhead cranes that can be allowed to exist simultaneously for each transfer crane is 8. When it is determined that the number of overhead cranes on a bridge track reaches 8, the bridge track is not selected.

[0056] Therefore, when selecting the bridge track 400, it is possible to first determine whether the number of overhead cranes at the first artificial intervention track 450 and / or the number of overhead cranes on the bridge track meet the requirements. If not, then select a bridge track according to the selection principles of the first embodiment and / or the second embodiment mentioned above to implement the transfer instruction.

[0057] Further, when the number of overhead cranes at the first artificial intervention track reaches an upper limit, the system suspends the use of the bridge track where the first artificial intervention track is located, for example, the system sets the use status mark of the bridge track to be closed or unavailable, etc., until the number of overhead cranes at the first artificial intervention track is lower than the upper limit, then the system resumes the use of the bridge track. The upper limit is greater than the warning value and less than the maximum value of the transfer overhead cranes that can be parked on the artificial intervention track.

[0058] Furthermore, when the transfer crane determines at the first re-confirmation point 401 that data switching has not been completed and needs to enter the first manual intervention track 450, the number of occupied parking points at the first manual intervention track may have reached the set warning value or even the upper limit value. Therefore, the transfer crane that needs to enter the first manual intervention track 450 can first confirm whether it can enter the first manual intervention track 450 and which parking point of the first manual intervention track 450 to enter.

[0059] Specifically, when the transfer crane determines that the data switching has not been completed at the first reconfirmation point 401, at this time, if the transfer crane has established a connection with the TCS of the second building 200, but the operation data switching has not been completed, the transfer crane asks the TCS of the second building 200 whether it can enter the first manual intervention track 450. If the transfer crane has not established a connection with the TCS of the second building 200 when passing the first reconfirmation point, the transfer crane switches to a communication connection with the TCS of the first building 100 and asks it whether it can enter the first manual intervention track 450.

[0060] The TCS of building one 100 and the TCS of building two 200 communicate regarding the transfer crane's inquiry as to whether it can enter the first manual intervention track 450, so that when the transfer crane asks the TCS of building one 100 or the TCS of building two 200 whether it can enter the first manual intervention track 450, the TCS of building one 100 and the TCS of building two 200 can know how many transfer cranes have inquired about entering the first manual intervention track, and at the same time can determine whether the transfer crane currently inquiring can enter the first manual intervention track 450 in combination with the situation of the transfer crane that has completed manual intervention at the first manual intervention track 450.

[0061] For example, it is assumed that there are four parking points at the first manual intervention track 450, and the four parking points are defined as the first parking point, the second parking point, the third parking point and the fourth parking point in sequence, the first parking point is close to the building 100, and the fourth parking point is close to the building 200, and it is assumed that the warning value is 4. In addition, when each transfer crane completes the manual intervention and leaves the first manual intervention track 450, the transfer crane behind it can be manually controlled to move forward one parking position before manual intervention is performed, and each transfer crane, after moving to the parking position, feeds back the information that it has moved to the parking position to the TCS of the building 100 and the TCS of the building 2 200. Alternatively, each transfer crane at the first manual intervention track may send a pursuit request to the TCS of Building 1 or Building 2 connected to it, i.e., requesting the transfer crane in front of it to leave the current position; when the TCS of Building 1 or Building 2 determines that the transfer crane at a position has completed manual intervention and left the first manual intervention track, the TCS of Building 1 or Building 2 sends an instruction to move forward one position to each transfer crane still located at the first manual intervention track.

[0062] When the first transfer crane asks the TCS of building one 100 or the TCS of building two 200 whether it can enter the first manual intervention track 450, the TCS of building one 100 and the TCS of building two 200 know that the number of cranes at the first manual intervention track 450 is 0, and the first transfer crane can enter the first parking point of the first manual intervention track 450.

[0063] When the second transfer crane asks the TCS of building one 100 or the TCS of building two 200 whether it can enter the first manual intervention track 450, if it is determined that the first transfer crane has not completed manual intervention at the first manual intervention track 450, at this time, the TCS of building one 100 and the TCS of building two 200 determine that the number of cranes at the first manual intervention track 450 is 1 and the first parking position is occupied, then the second transfer crane can enter the first manual intervention track 450 and park at the second parking position. At this time, it is determined that the number of cranes at the first manual intervention track 450 is 2.

[0064] If it is determined that the first transfer crane has completed manual intervention at the first parking point and has fed back the completion of data switching to the TCS of Building 2 200, then the TCS of Building 1 100 and the TCS of Building 2 200 determine that there is no transfer crane at the first manual intervention track 450, that is, the number of cranes at the first manual intervention track 450 is restored to 0. At this time, it is determined that the second transfer crane can enter the first parking position of the first manual intervention track 450.

[0065] When the third transfer crane asks whether it can enter the first manual intervention track 450, if it is determined that the first transfer crane at the first parking position has not yet completed manual intervention, the TCS of building one 100 and the TCS of building two 200 determine that the number of cranes at the first manual intervention track 450 is 2 and the second parking position is occupied, and the third transfer crane can enter the first manual intervention track 450 and park at the third parking position.

[0066] If it is determined that the second transfer crane has moved to the first parking position, the TCS of the building 100 and the TCS of the building 200 determine that the number of cranes at the first manual intervention track 450 is 1 and the first parking position is occupied, and the third transfer crane can enter the second parking position.

[0067] If it is determined that the second transfer crane has completed data switching with manual intervention, the TCS of the building 100 and the TCS of the building 2 200 determine that the number of cranes at the first manual intervention track 450 is 0, and determine that the third crane can enter the first parking position.

[0068] When the fourth transfer crane asks whether it can enter the first manual intervention track 450, if it is determined that the first transfer crane at the first parking position has not completed manual intervention, the TCS of building one 100 and the TCS of building two 200 determine that the number of cranes at the first manual intervention track 450 is 3 and the third parking position is occupied, then it is determined that the fourth transfer crane can enter the fourth parking position of the first manual intervention track 450.

[0069] If it is determined that the third transfer crane is located at the first parking position or the second parking position, the TCS of the building 100 and the TCS of the building 200 determine that the number of cranes at the first manual intervention track 450 is 1 or 2, and the first parking position or the second parking position is occupied, and the fourth transfer crane can move to the second parking position or the third parking position behind the third transfer crane.

[0070] If it is determined that the third transfer crane has completed data switching by manual intervention, the TCS of the building 100 and the TCS of the building 2 200 determine that the number of cranes at the first manual intervention track 450 is 0, and the fourth transfer crane can be moved to the first parking position.

[0071] When the fifth transfer crane inquires whether it can enter the first manual intervention track 450, if it is determined that the first transfer crane has not yet completed manual intervention, the TCS of the building 100 and the TCS of the building 200 determine that the number of cranes at the first manual intervention track 450 is 4, and determine that the fifth transfer crane cannot enter the first manual intervention track 450. Therefore, the fifth transfer crane needs to continue to move along the second main road and transfer to the first main road through the second turning track 440 for circulation. At the same time, it confirms whether the data switching is completed when passing through the first switching confirmation point 480 again. Of course, the above problem can be avoided by controlling the number of cranes that can enter each of the bridge tracks. For example, when the number of cranes that can enter each of the bridge tracks is less than the number of transfer cranes that can be parked at the manual intervention track, the problem that the transfer crane cannot enter the first manual intervention track can be avoided. In addition, when the transfer crane resumes communication with the TCS of building one and cannot obtain a response from the TCS of building one, the transfer crane also continues to circulate along the second main road and transfers to the first main road via the second turning rail 440, and can enter the first manual intervention track to wait for manual intervention if no new instructions are obtained after circulating for a certain period of time.

[0072] When it is determined that the fourth transfer crane is at the first parking position, the second parking position, or the third parking position, it is determined that the fifth transfer crane can enter the second parking position, the third parking position, or the fourth parking position.

[0073] If it is determined that the fourth transfer crane has completed data switching through manual intervention, the fifth transfer crane may be moved to the first parking position.

[0074] And so on, so as to continuously control whether each transfer crane can enter the first manual intervention track 450.

[0075] Of course, in other embodiments, an image recognition device may be provided on the overhead crane, and the image recognition device is used to identify whether there are other overhead cranes in front of the overhead crane. The specific image recognition method is a known technology and will not be described here. Thus, when the transfer overhead crane enters the first artificial intervention track 450, the transfer overhead crane can determine the parking point to be stopped at the first artificial intervention track 450 according to the image recognition situation. Of course, in other embodiments, a laser obstacle avoidance radar system may also be provided on each overhead crane, and the laser obstacle avoidance radar is used to determine whether there are other overhead cranes in front of it and maintain a safe distance from the overhead crane in front.

[0076] Furthermore, when the TCS of the building 100 executes two transfer instructions through a bridge track 400, it can feedback to the TCS of the building 2 200 that the data switching is completed when the transfer crane that executes the previous transfer instruction passes the first switching confirmation point 480 or passes the first re-confirmation point 401, and then make the transfer crane that executes the second transfer instruction enter the first main track 410.

[0077] At the same time, when receiving the transfer instruction, the TCS of the building 100 determines whether the number of overhead cranes in the building 200 has reached the maximum number of overhead cranes. If so, the TCS of the building 200 sends a transfer request to the TCS of a selected building based on the number of overhead cranes of other buildings connected to the building 200, and the number of overhead cranes of the selected building is less than the maximum number of overhead cranes set for the selected building.

[0078] For example, if Building 2 200 is connected to Building 1 100 and Building 3 respectively through bridge rails 400, when Building 1 100 needs to transport materials to Building 2 200 by a crane, if it is determined that the number of cranes in Building 2 200 has reached the maximum number of cranes, then at least one crane in Building 2 200 needs to be transferred to other buildings. Assuming that the number of cranes in Building 1 100 is close to the maximum number of cranes corresponding to Building 1 100, and the number of cranes in Building 3 is much smaller than the maximum number of cranes corresponding to Building 3, then the TCS of Building 2 200 immediately sends a transfer request to the TCS of Building 3 to transfer an idle crane in Building 2 200 to Building 3.

[0079] When Building 2 is the initial building and Building 1 is the target building, the transfer process can be executed by referring to the transfer process when Building 1 is the initial building and Building 2 is the target building, which will not be elaborated here.

[0080] Example 2 This embodiment discloses a method for controlling an overhead crane to work across buildings.

[0081] When the transfer crane needs to enter the manual intervention track configured for the initial building, it is also confirmed whether it can enter according to the process disclosed in Example 1.
