Description

Technical Field

[0001] This invention relates to the field of automatic control, and in particular to a suspended chain blockage intelligent alarm processing management system and method. Background Technology

[0002] Currently, overhead conveyor lines are continuous transport equipment with enclosed spatial routes. They are mainly used for the continuous flow transport of workpieces and materials within or between workshops. Based on the method of transporting objects, they can be divided into general-purpose and light-duty traction-type overhead conveyors, and general-purpose and light-duty accumulation-type push-type overhead conveyors. Overhead conveyor lines mainly consist of overhead tracks, traction chains, carriages (trolleys or hangers), lifting devices, redirection devices, drive units, tensioning devices, and safety devices. Their working principle is that the drive unit drives the traction chain to run on the track, and the carriages are connected to the traction chain and move with it. The lifting devices are used to fix and suspend materials, allowing them to move along with the carriages. When transporting materials such as refrigerator door liners, the materials need to be placed on cranes or other carriers suspended on the overhead chain, and then transported by the overhead conveyor line to the next processing station.

[0003] The existing technical solutions mentioned above have the following drawbacks: during the transportation process of the overhead chain conveyor, materials are usually loaded and unloaded manually, so the loading and unloading time is unstable, and the crane may pile up in a certain part, causing blockage. Summary of the Invention

[0004] In order to reduce crane blockage, this application provides an intelligent alarm management system and method for handling chain blockage.

[0005] On the one hand, the intelligent alarm handling and management method for suspended chain blockage provided in this application adopts the following technical solution:

[0006] A method for handling and managing intelligent alarms for suspended chain blockages includes the following steps:

[0007] A buffer zone, a pre-blocking position, a waiting position, and a full-load position are set on the overhead conveyor. The pre-blocking position is located in the buffer zone, the waiting position is located at the front end of the buffer zone along the transport direction of the transport line, and the full-load position is located at the end of the buffer zone along the transport direction of the transport line. The transport line has a first operating position and a second operating position located in front of and behind the buffer zone, respectively.

[0008] When the first operating position transmits a signal, it blocks the crane that is arriving at the first operating position;

[0009] When the first operating position stops transmitting signals, the crane blocking the first operating position stops;

[0010] Detect the number and location of cranes located in the buffer area;

[0011] When a crane is detected to have reached the waiting position, its movement is blocked.

[0012] When the second operation bit transmits a signal, release one crane in the waiting bit and re-check whether there is a crane in the waiting bit;

[0013] When a crane is detected at the pre-blocking position, a timer starts, and when the timer reaches the set time, a pre-blocking alarm is issued.

[0014] When a crane is detected in a full load position, a timer is started. When the timer reaches the set time, an overload alarm is issued and the crane in the waiting position is stopped from being blocked. At the same time, the transmission signal of the second operation position is blocked.

[0015] The timer is reset when no crane is detected in the buffer area.

[0016] By adopting the above scheme, a buffer zone is marked on the overhead conveyor belt, located before the next process step. Workers at the first operating position stop and load the crane. When the crane needs to proceed to the next process step, it first enters the buffer zone, where workers at the next operating position control its passage. If the crane's release speed at the first operating position is too fast, or if the workers at the second operating position process the process too slowly, cranes will accumulate in the buffer zone. When the accumulation reaches the pre-blockage position, the system will time whether the crane is stopped at the pre-blockage position. If the crane is stopped at the pre-blockage position, it indicates an impending blockage, and the system will issue an alarm to the workers. When the accumulation reaches the full load position, the system will time whether the crane is stopped at the full load position. If the crane is stopped at the full load position, an alarm will be immediately issued, and the system will forcibly control the crane's passage in the buffer zone, while simultaneously blocking signal transmission at the second operating position to prevent further obstruction of crane passage in a short period. This effectively reduces crane blockages on the overhead conveyor belt, ensuring stable production line operation.

[0017] Preferably, the step of "detecting the number and location of cranes located in the buffer area" further includes:

[0018] RFID scanners are installed at the pre-blocking positions, waiting positions, and full positions in the buffer area;

[0019] Install RFID cards on each crane;

[0020] When the crane reaches the full load position, the RFID scanner scans the RFID card and records the crane's position. When the RFID card leaves the RFID scanner, it is recorded that the crane has entered the buffer area.

[0021] When the crane reaches the pre-blocking position, the RFID scanner scans the RFID card and records the crane's position.

[0022] When the crane arrives at the waiting position, the RFID scanner scans the RFID card and records the crane's position. When the RFID card leaves the RFID scanner, it is recorded that the crane has left the buffer area.

[0023] By adopting the above scheme, the RFID card can record the number information of each crane, and the RFID scanner can quickly identify the information of the RFID card, ensuring that the system can accurately identify the crane in the pre-block position, waiting position and full position.

[0024] Preferably, the following steps are also included:

[0025] Set up an order database to receive and store input order information, including crane loading information. The crane loading information is arranged in the order sequence and a backup information table is created.

[0026] Displays the sorted crane loading information;

[0027] When the signal of the first operation bit is received, mark the crane loading information at the very beginning of the currently displayed crane loading information;

[0028] When the signal of the first operation bit is not received, the marked crane loading information is moved from the order information to the spare information table;

[0029] The order database receives the entered order completion information and deletes the crane loading information from the standby information table based on the order completion information;

[0030] When an overload alarm is issued, stop modifying the order information and read the crane loading information quantity from the standby information table;

[0031] When the number of times the signal of the first operation bit is received and lost reaches the number of crane loading information in the spare information table, the modification of the order information is resumed.

[0032] By adopting the above scheme, under normal circumstances, the system will display the information of the items that the current crane needs to load. The displayed information will gradually change as the crane moves, which is convenient for the staff at the first operating position to load the crane. When the buffer area is full, in addition to releasing the cranes in the buffer area, the system will also record the loading information of the released cranes. If the released cranes have their goods taken away in the next process, the corresponding record will be deleted through the order completion information. The remaining cranes that cannot take away their goods will move to the next process again after returning to the first operating position. At this time, since the staff does not need to load the cranes at the first operating position, the system will automatically stop changing the displayed information. The system will only resume modifying the order information after calculating that the loaded cranes have passed the first operating position.

[0033] Preferably, the following steps are also included:

[0034] Set the maximum number of empty cars;

[0035] When the signal from the first operating position is no longer received, the number of cranes passing through the full position is recorded, and the number of empty cranes is obtained by subtracting one from the recorded number of cranes.

[0036] When the number of recorded empty cars is greater than one, an empty car notification is issued;

[0037] When the number of recorded empty cranes exceeds the maximum number of empty cranes, an empty crane alarm is issued and it is determined whether the crane currently in the waiting position is not empty.

[0038] If it is determined that the crane currently in the waiting position is empty, then calculate the number of empty cranes in the current buffer area, stop blocking the crane in the waiting position, and at the same time block the transmission signal of the second operation position and record the number of cranes that have passed through the waiting position.

[0039] When the number of cranes passing through the waiting position equals the calculated number of empty cranes, the second operation position transmission signal is restored.

[0040] By adopting the above scheme, various situations may occur during the production process that require the first operating position to release empty cars into the buffer area. Since these empty cars will not participate in the next process, the system can automatically detect the number of empty cars in the buffer area. When the number of empty cars reaches the maximum number of empty cars, the system will release all empty cars when the first empty car in the buffer area arrives at the waiting position, thus avoiding empty cars blocking the suspension chain.

[0041] Preferably, the step "if it is determined that the crane currently in the waiting position is empty, then calculate the number of empty cranes in the current buffer area" further includes:

[0042] After issuing an empty crane notification, the position of the first empty crane is calculated based on the number of cranes in the buffer area and the number of cranes that have passed the waiting position;

[0043] If the first empty car passes through the waiting area, the number of empty cars is reduced by one and the next empty car is made the first empty car.

[0044] If the crane currently in the waiting position is determined to be empty, the recorded number of empty cranes will be used as the number of empty cranes in the buffer.

[0045] By adopting the above scheme, the system can accurately calculate the number and specific location of empty cars in the buffer area, so as to ensure that all empty cars can be released accurately and that cranes loaded with goods will not be released.

[0046] On the other hand, the intelligent alarm processing and management system for suspended chain blockage provided in this application adopts the following technical solution:

[0047] A suspended chain blockage intelligent alarm processing and management system includes a region division module, a crane monitoring module, an operation control module, an automatic blocking module, and a blockage alarm module;

[0048] The area division module has a pre-set overhead conveyor engineering diagram, on which buffer areas, pre-blocking positions, waiting positions and full-load positions are set, and on the transport line, buffer areas, pre-blocking positions, waiting positions and full-load positions are set.

[0049] The crane monitoring module detects the number and location of cranes in the buffer area, and detects whether there are cranes in the first operating position, second operating position, pre-blocking position, waiting position and full position.

[0050] The operation control module connects the first operation position and the second operation position. When the first operation position transmits a signal, it blocks the crane that arrives at the first operation position. When the first operation position stops transmitting a signal, it stops blocking the crane located at the first operation position. When the second operation position transmits a signal, it releases one crane in the waiting position and re-detects whether there is a crane in the waiting position.

[0051] The automatic blocking module is connected to the waiting position and blocks the crane from moving when it is detected that the crane has arrived at the waiting position.

[0052] The congestion alarm module connects the pre-blocking position and the full-load position. The congestion alarm module has a preset time. When a crane is detected at the pre-blocking position, the timer starts. When the timer reaches the preset time, the congestion alarm module issues a pre-blocking alarm. When a crane is detected at the full-load position, the timer starts. When the timer reaches the preset time, the congestion alarm module issues an overload alarm and stops blocking cranes in the waiting position. At the same time, it blocks the transmission of signals from the operation control module. When no crane is detected in the buffer area, the timer is reset.

[0053] By adopting the above scheme, a buffer zone is marked on the overhead conveyor belt, located before the next process step. Workers at the first operating position stop and load the crane. When the crane needs to proceed to the next process step, it first enters the buffer zone, where workers at the next operating position control its passage. If the crane's release speed at the first operating position is too fast, or if the workers at the second operating position process the process too slowly, cranes will accumulate in the buffer zone. When the accumulation reaches the pre-blockage position, the system will time whether the crane is stopped at the pre-blockage position. If the crane is stopped at the pre-blockage position, it indicates an impending blockage, and the system will issue an alarm to the workers. When the accumulation reaches the full load position, the system will time whether the crane is stopped at the full load position. If the crane is stopped at the full load position, an alarm will be immediately issued, and the system will forcibly control the crane's passage in the buffer zone, while simultaneously blocking signal transmission at the second operating position to prevent further obstruction of crane passage in a short period. This effectively reduces crane blockages on the overhead conveyor belt, ensuring stable production line operation.

[0054] Preferably, the crane monitoring module is equipped with RFID scanners at the pre-blocking position, waiting position, and full-load position in the buffer area, and an RFID card is set on each crane. When the crane reaches the full-load position, the RFID scanner scans the RFID card and records the crane's position. When the RFID card leaves the RFID scanner, it is recorded that the crane has entered the buffer area. When the crane reaches the pre-blocking position, the RFID scanner scans the RFID card and records the crane's position. When the crane reaches the waiting position, the RFID scanner scans the RFID card and records the crane's position. When the RFID card leaves the RFID scanner, it is recorded that the crane has left the buffer area.

[0055] By adopting the above scheme, the RFID card can record the number information of each crane, and the RFID scanner can quickly identify the information of the RFID card, ensuring that the system can accurately identify the crane in the pre-block position, waiting position and full position.

[0056] Preferably, it also includes a data storage module and an order instruction module;

[0057] The data storage module receives and stores the input order information, which includes crane loading information. The crane loading information is arranged in the order sequence to create a backup information table. The data storage module receives the input order completion information and deletes the crane loading information from the backup information table based on the order completion information.

[0058] When the operation control module receives the signal from the first operation position, it transmits the first signal to the order indication module.

[0059] When the congestion alarm module issues an overload alarm, it controls the data storage module to stop modifying the order information and transmits a second signal to the order indication module.

[0060] The order indication module calls the crane loading information from the data storage module and displays the sorted crane loading information. When the order indication module receives the first signal, it marks the crane loading information at the forefront of the currently displayed crane loading information. When the first signal is not received, the marked crane loading information is moved from the order information to the backup information table. When the order indication module receives the second signal, it reads the number of crane loading information in the backup information table. When the number of times the first signal is received and lost reaches the number of crane loading information in the backup information table, the modification of the order information is restored.

[0061] By adopting the above scheme, under normal circumstances, the system will display the information of the items that the current crane needs to load. The displayed information will gradually change as the crane moves, which is convenient for the staff at the first operating position to load the crane. When the buffer area is full, in addition to releasing the cranes in the buffer area, the system will also record the loading information of the released cranes. If the released cranes have their goods taken away in the next process, the corresponding record will be deleted through the order completion information. The remaining cranes that cannot take away their goods will move to the next process again after returning to the first operating position. At this time, since the staff does not need to load the cranes at the first operating position, the system will automatically stop changing the displayed information. The system will only resume modifying the order information after calculating that the loaded cranes have passed the first operating position.

[0062] Preferably, it also includes an empty vehicle alarm module;

[0063] When the operation control module stops receiving the signal from the first operation position, it transmits an empty crane signal to the crane monitoring module.

[0064] After receiving the empty crane signal, the crane monitoring module starts recording the number of cranes that have passed through the full load area, subtracts one from the recorded number of cranes to obtain the number of empty cranes, and transmits the number of empty cranes to the empty crane alarm module.

[0065] The empty vehicle alarm module is set with a maximum number of empty vehicles. After receiving the number of empty vehicles, the empty vehicle alarm module issues an empty vehicle prompt when the received number of empty vehicles is greater than one. When the number of empty vehicles is greater than the maximum number of empty vehicles, it issues an empty vehicle alarm and determines whether the crane currently in the waiting position is not empty. If it determines that the crane currently in the waiting position is empty, it calculates the number of empty vehicles in the current buffer area, stops blocking the crane in the waiting position, blocks the transmission signal of the second operation position, and records the number of cranes passing through the waiting position. When the number of cranes passing through the waiting position is equal to the calculated number of empty vehicles, it resumes the transmission signal of the second operation position.

[0066] By adopting the above scheme, various situations may occur during the production process that require the first operating position to release empty cars into the buffer area. Since these empty cars will not participate in the next process, the system can automatically detect the number of empty cars in the buffer area. When the number of empty cars reaches the maximum number of empty cars, the system will release all empty cars when the first empty car in the buffer area arrives at the waiting position, thus avoiding empty cars blocking the suspension chain.

[0067] Preferably, after the empty vehicle alarm module issues an empty vehicle prompt, it calculates the position of the first empty vehicle based on the number of cranes in the buffer area and the number of cranes that have passed the waiting position. If the first empty vehicle passes the waiting position, the number of empty vehicles is decremented by one and the next empty vehicle is designated as the first empty vehicle. If the crane currently in the waiting position is determined to be empty, the recorded number of empty vehicles is used as the number of empty vehicles in the buffer area.

[0068] By adopting the above scheme, the system can accurately calculate the number and specific location of empty cars in the buffer area, so as to ensure that all empty cars can be released accurately and that cranes loaded with goods will not be released.

[0069] In summary, the present invention has the following beneficial effects:

[0070] 1. An alarm will be issued when the crane is likely to be blocked or when a blockage occurs. The crane will be automatically cleared when a blockage occurs, which can effectively reduce the occurrence of crane blockage on the suspension chain and ensure the stable operation of the production line.

[0075] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0076] Example 1: This application discloses a method for intelligent alarm processing and management of suspended chain blockage, such as... Figure 1 As shown, the specific steps are as follows:

[0077] S100. Set a buffer zone 9, a pre-block position 94, a waiting position 93, and a full-load position 95 on the overhead conveyor. The pre-block position 94 is located within the buffer zone 9. The waiting position 93 is located at the front end of the buffer zone 9 along the transport line direction. The full-load position 95 is located at the end of the buffer zone 9 along the transport line direction. The transport line has a first operating position 91 and a second operating position 92 located in front of and behind the buffer zone 9, respectively. Set the maximum number of empty vehicles.

[0078] S101. Set up an order database to receive and store the input order information, including crane loading information. The crane loading information is arranged in the order sequence and a backup information table is created.

[0079] S200: Displays the sorted crane loading information.

[0080] S300, when the first operating position 91 transmits a signal, it blocks the crane that arrives at the first operating position 91.

[0081] S301, when the first operation position 91 stops transmitting signals, stop the crane that is blocking the first operation position 91.

[0082] S302. When the signal of the first operation bit 91 is received, mark the crane loading information at the forefront of the currently displayed crane loading information.

[0083] S303. When the signal of the first operation bit 91 is not received, the marked crane loading information is moved from the order information to the spare information table.

[0084] S304. The order database receives the input order completion information and deletes the crane loading information from the standby information table based on the order completion information.

[0085] S305. When the signal from the first operation position 91 is no longer received, start recording the number of cranes that have passed through the full position 95, and subtract one from the recorded number of cranes to obtain the number of empty cranes.

[0086] S400: Detect the number and location of cranes located in buffer area 9.

[0087] S401. Install RFID scanners at the pre-block position 94, waiting position 93 and full position 95 in the buffer area 9.

[0088] S402. Install an RFID card on each crane.

[0089] S403. When the crane reaches the full load position 95, the RFID scanner scans the RFID card and records the crane's position. When the RFID card leaves the RFID scanner, it is recorded that the crane has entered the buffer area 9.

[0090] S404. When the crane reaches the pre-blocking position 94, the RFID scanner scans the RFID card and records the crane's position.

[0091] S405. When the crane arrives at waiting position 93, the RFID scanner scans the RFID card and records the crane's position. When the RFID card leaves the RFID scanner, the crane leaves the buffer area 9.

[0092] S500: When the crane is detected to have reached the waiting position 93, prevent the crane from moving.

[0093] S501. When the second operation bit 92 transmits a signal, release one crane from the waiting bit 93 and re-check whether there is a crane in the waiting bit 93.

[0094] S600: When the pre-blocking position 94 detects a crane, a timer starts. When the timer reaches the set time, a pre-blocking alarm is issued. The timer stops when the pre-blocking position 94 does not detect a crane.

[0095] S601. When a crane is detected at the full load position 95, a timer starts. When the timer reaches the set time, an overload alarm is issued and the crane in the waiting position 93 is stopped from being blocked. At the same time, the transmission signal of the second operation position 92 is blocked. When no crane is detected at the full load position 95, the timer stops.

[0096] S602. Stop modifying the order information and read the crane loading information quantity from the standby information table.

[0097] S603. When the number of times the signal of the first operation bit 91 is received and lost reaches the number of crane loading information in the spare information table, the modification of the order information is resumed.

[0098] S604. When no crane is detected in buffer 9, reset the timer.

[0099] S700: When the number of recorded empty cranes is greater than one, an empty crane prompt is issued. After issuing the empty crane prompt, the position of the first empty crane is calculated based on the number of cranes in buffer area 9 and the number of cranes that have passed waiting position 93.

[0100] S701. If the first empty car passes through waiting position 93, then decrease the number of empty cars by one and make the next empty car the first empty car.

[0101] S702. If it is determined that the crane currently in waiting position 93 is empty, the number of empty cranes recorded will be used as the number of empty cranes in buffer 9.

[0102] S703. When the number of recorded empty cranes is greater than the maximum number of empty cranes, an empty crane alarm is issued and it is determined whether the crane currently in waiting position 93 is not empty.

[0103] S704. If it is determined that the crane currently located at waiting position 93 is empty, calculate the number of empty cranes in the current buffer area 9, stop blocking the crane located at waiting position 93, and at the same time block the transmission signal of the second operation position 92 and record the number of cranes that have passed through waiting position 93.

[0104] S705. When the number of cranes passing through waiting bit 93 equals the calculated number of empty cranes, the second operation bit 92 is restored to transmit the signal.

[0105] The implementation principle of the intelligent alarm management and method for overhead conveyor blockage in this application embodiment is as follows: A buffer zone 9 is marked on the overhead conveyor, located before the next process. Workers at the first operating position 91 stop and load the crane. When the crane needs to enter the next process, it first enters the buffer zone 9. Workers at the next process control the crane's passage from the second operating position 92. If the crane's release speed at the first operating position 91 is too fast, or if the worker at the second operating position 92 processes the process too slowly, the crane will accumulate in the buffer zone 9. When it accumulates to the pre-blockage position 94, the system will determine whether the crane is stopped at the pre-blockage position 94 through timing. If the crane stops at the pre-blockage position 94, it indicates that a blockage is about to occur, and the system will issue an alarm to the workers. When the inventory reaches the full capacity of 95, the system will use a timer to determine whether the crane is stopped at the full capacity of 95. If the crane stops at the full capacity of 95, an alarm will be issued immediately and the crane passage in the buffer area 9 will be forcibly controlled. At the same time, the signal transmission of the second operation position 92 will be blocked to prevent the crane passage from being blocked again in a short period of time. This can effectively reduce the situation of the crane being blocked on the suspension chain and ensure the stable operation of the production line.

[0106] Example 2: This application discloses an intelligent alarm processing and management system for suspended chain blockage, such as... Figure 2 As shown, it includes the aforementioned area division module 1, crane monitoring module 2, operation control module 3, automatic blocking module 4, blockage alarm module 5, data storage module 6, order indication module 7, and empty vehicle alarm module 8.

[0107] like Figure 1 and Figure 2 As shown, the area division module 1 has a pre-set overhead conveyor engineering diagram. On the overhead conveyor engineering diagram, a buffer zone 9, a pre-blocking position 94, a waiting position 93, and a full-load position 95 are set. On the transport line, a buffer zone 9, a pre-blocking position 94, a waiting position 93, and a full-load position 95 are set.

[0108] like Figure 2As shown, the crane monitoring module 2 detects the number and position of cranes located in the buffer area 9, and detects whether there are cranes at the first operation position 91, the second operation position 92, the pre-blocking position 94, the waiting position 93, and the full position 95. The crane monitoring module 2 sets up RFID scanners at the pre-blocking position 94, the waiting position 93, and the full position 95 in the buffer area 9, and sets an RFID card on each crane. When a crane reaches the full position 95, the RFID scanner scans the RFID card and records the crane's position. When the RFID card leaves the RFID scanner, it records that the crane has entered the buffer area 9. When a crane reaches the pre-blocking position 94, the RFID scanner scans the RFID card and records the crane's position. When a crane reaches the waiting position 93, the RFID scanner scans the RFID card and records the crane's position. When the RFID card leaves the RFID scanner, it records that the crane has left the buffer area 9. After receiving the empty crane signal, crane monitoring module 2 begins recording the number of cranes passing through full-load position 95. It subtracts one from the recorded crane count to obtain the number of empty cranes and transmits this number to empty crane alarm module 8. RFID cards can record the identification number of each crane, and RFID scanners can quickly identify the information on the RFID cards, ensuring the system can accurately identify cranes at pre-block position 94, waiting position 93, and full-load position 95.

[0109] like Figure 2 As shown, the operation control module 3 is connected to the first operation position 91 and the second operation position 92. When the first operation position 91 transmits a signal, it blocks the crane that arrives at the first operation position 91 and transmits a first signal to the order indication module 7. When the first operation position 91 stops transmitting a signal, it stops blocking the crane located at the first operation position 91 and transmits an empty crane signal to the crane monitoring module 2. When the second operation position 92 transmits a signal, it releases one crane at the waiting position 93 and re-detects whether there is a crane at the waiting position 93.

[0110] like Figure 2 As shown, the automatic blocking module 4 is connected to the waiting position 93. When the crane is detected to have arrived at the waiting position 93, the module blocks the crane from moving.

[0111] like Figure 2 As shown, the congestion alarm module 5 is connected to the pre-blocking position 94 and the full-load position 95. The congestion alarm module 5 has a preset time. When the pre-blocking position 94 detects a crane, it starts timing. When the time reaches the preset time, the congestion alarm module 5 issues a pre-blocking alarm. When the full-load position 95 detects a crane, it starts timing. When the time reaches the preset time, the congestion alarm module 5 issues an overload alarm and stops blocking the crane located at the waiting position 93. At the same time, it blocks the operation control module 3 from transmitting signals, controls the data storage module 6 to stop modifying the order information, and transmits a second signal to the order indication module 7. When no crane is detected in the buffer area 9, the timer is reset.

[0112] like Figure 2As shown, the data storage module 6 receives and stores the input order information, which includes crane loading information. The crane loading information is arranged in the order sequence to create a backup information table. The data storage module 6 receives the input order completion information and deletes the crane loading information from the backup information table based on the order completion information.

[0113] like Figure 2 As shown, the order indication module 7 calls the crane loading information from the data storage module 6. The order indication module 7 displays the sorted crane loading information. When the order indication module 7 receives the first signal, it marks the crane loading information at the forefront of the currently displayed crane loading information. When the first signal is not received, the marked crane loading information is moved from the order information to the spare information table. When the order indication module 7 receives the second signal, it reads the number of crane loading information in the spare information table. When the number of times the first signal is received and lost reaches the number of crane loading information in the spare information table, the modification of the order information is restored.

[0114] Under normal circumstances, the system will display the information of the items that the crane needs to load. The displayed information will gradually change as the crane moves, which will facilitate the loading of the crane by the staff at the first operating position 91. When the buffer area 9 is full, in addition to releasing the cranes in the buffer area 9, the system will also record the loading information of the released cranes. If the released cranes have their goods taken away in the next process, the corresponding record will be deleted through the order completion information. The remaining cranes that cannot take away their goods will move to the next process again after returning to the first operating position 91. At this time, since the staff does not need to load the cranes at the first operating position 91, the system will automatically stop changing the displayed information. The system will resume modifying the order information only after it has calculated that the loaded cranes have passed the first operating position 91.

[0115] like Figure 2 As shown, the empty vehicle alarm module 8 is set with a maximum number of empty vehicles. After receiving the number of empty vehicles, the empty vehicle alarm module 8 issues an empty vehicle prompt when the received number of empty vehicles is greater than one. It calculates the position of the first empty vehicle based on the number of cranes in the buffer area 9 and the number of cranes that have passed the waiting position 93. If the first empty vehicle passes the waiting position 93, the empty vehicle count is decremented by one and the next empty vehicle is set as the first empty vehicle. If the crane currently at the waiting position 93 is determined to be empty, the recorded number of empty vehicles is used as the number of empty vehicles in the buffer area 9. When the number of empty vehicles is greater than the maximum number of empty vehicles, an empty vehicle alarm is issued and it is determined whether the crane currently at the waiting position 93 is not empty. If the crane currently at the waiting position 93 is determined to be empty, the number of empty vehicles in the current buffer area 9 is calculated, the crane at the waiting position 93 is stopped from being blocked, the second operation position 92 transmission signal is blocked, and the number of cranes that have passed the waiting position 93 is recorded. When the number of cranes that have passed the waiting position 93 is equal to the calculated number of empty vehicles, the second operation position 92 transmission signal is restored.
