Description

Technical Field

[0001] The present invention relates to the field of automatic control, and in particular to an intelligent alarm processing and management system and method for suspension chain blockage. Background Art

[0002] At present, the suspension chain conveyor line is a continuous transportation device with a spatially enclosed line. It is mainly used for the continuous flow transportation of workpieces and articles inside the workshop or between workshops. According to the method of transporting objects, it can be divided into general and light traction-type suspension transportation, and general and light accumulation-type push-type suspension transportation. The suspension chain conveyor line mainly consists of an overhead track, a traction chain, a carriage (cart or hanging piece), a lifting device, a redirecting device, a driving device, a tensioning device, and a safety device, etc. Its working principle is that the driving device drives the traction chain to run on the track, and the carriage is connected to the traction chain and moves along with the movement of the traction chain. The lifting device is used to fix and suspend the material, so that the material moves along with the carriage. When transporting materials such as refrigerator door linings, the materials need to be placed on carriers such as cranes hanging on the suspension chain and transported to the next processing station by the suspension chain conveyor line.

[0003] The above-mentioned existing technical solutions have the following defects: During the transportation process of the suspension chain conveyor line, manual loading and unloading is usually adopted, so the loading and unloading time is unstable, and it may occur that the cranes pile up in a certain part and cause blockage. Summary of the Invention

[0004] In order to reduce the situation of crane blockage, the present application provides an intelligent alarm processing and management system and method for suspension chain blockage.

[0005] On the one hand, an intelligent alarm processing and management method for suspension chain blockage provided by the present application adopts the following technical solutions: An intelligent alarm processing and management method for suspension chain blockage, comprising the following steps: Set a buffer zone, a pre-blocking position, a waiting position, and a full-load position on the suspension chain. The pre-blocking position is located within the buffer zone, the waiting position is located at the front end of the buffer zone along the transportation line direction, the full-load position is located at the end of the buffer zone along the transportation line direction, and the transportation line is respectively provided with a first operation position and a second operation position at the positions in front of and behind the buffer zone; When the first operation position transmits a signal, block the crane arriving at the first operation position; When the first operation position stops transmitting the signal, stop blocking the crane located at the first operation position; Detect the number and position of the cranes located in the buffer zone; When it is detected that the crane reaches the waiting position, block the movement of the crane; When the second operation position transmits a signal, release one crane at the waiting position and re-detect whether there is a crane at the waiting position; When a crane is detected at the pre-blocking position, the timing starts. When the timing reaches the set time, a pre-blocking alarm is issued. When a crane is detected at the full-load position, the timing starts. When the timing reaches the set time, an overload alarm is issued and the crane at the waiting position is blocked from moving, and at the same time, the signal transmission at the second operation position is blocked. When no crane is detected in the buffer area, the timing is reset.

[0006] By adopting the above solution, a buffer area is demarcated on the suspension chain. Before the next process, the staff stops the crane for loading at the first operation position. When the crane is about to enter the next process, it will first enter the buffer area, and the staff of the next process controls whether the crane can pass at the second operation position. If the release speed of the crane at the first operation position is too fast, or the staff at the second operation position processes the process too slowly, it will cause the cranes to pile up in the buffer area. When it piles up to the pre-blocking position, the system will judge whether the crane stays at the pre-blocking position through timing. If the crane stays at the pre-blocking position, it means that a blockage is about to occur, and the system will issue an alarm to notify the staff. When it piles up to the full-load position, the system will judge whether the crane stays at the full-load position through timing. If the crane stays at the full-load position, an alarm will be immediately issued and the cranes in the buffer area will be forcibly controlled to pass, and at the same time, the signal transmission at the second operation position will be blocked to prevent the crane from being blocked again in a short time. This can effectively reduce the occurrence of blockages of cranes on the suspension chain and ensure the stable operation of the production line.

[0007] Preferably, the step of "detecting the number and position of the cranes in the buffer area" further includes: RFID scanners are set at the pre-blocking position, waiting position and full-load position in the buffer area; RFID cards are set on each crane; When the crane reaches the full-load position, the RFID scanner scans the RFID card and records the position of the crane. When the RFID card leaves the RFID scanner, it records that the crane enters the buffer area; When the crane reaches the pre-blocking position, the RFID scanner scans the RFID card and records the position of the crane; When the crane reaches the waiting position, the RFID scanner scans the RFID card and records the position of the crane. When the RFID card leaves the RFID scanner, it records that the crane leaves the buffer area.

[0008] By adopting the above solution, 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 cranes at the pre-blocking position, waiting position and full-load position.

[0009] Preferably, the following steps are further included: Set up an order library to receive and store the input order information. The order information includes the crane loading information, and the crane loading information is sorted according to the order sequence number. Establish a backup information table; Display the sorted crane loading information; When receiving the signal from the first operation position, mark the crane loading information at the forefront among the currently displayed crane loading information; When the signal from the first operation position is not received, move the marked crane loading information from the order information to the backup information table; The order library receives the input order completion information and deletes the crane loading information in the backup information table according to the order completion information; When an overload alarm is issued, stop modifying the order information and read the quantity of the crane loading information in the backup information table; When the number of times of receiving and losing the signal from the first operation position reaches the quantity of the crane loading information in the backup information table, resume modifying the order information.

[0010] By adopting the above solution, under normal circumstances, the system will display the information of the items that the current crane needs to load. The displayed information gradually changes as the crane moves, which is convenient for the staff at the first operation position to load the goods. After the buffer area is full, in addition to releasing the cranes in the buffer area, the system will also record the crane loading information of the released cranes. If the goods on the released crane are taken away in the next process, the corresponding record will be deleted through the order completion information. The remaining cranes that are too late to have their goods taken away will move to the next process again after returning to the first operation position. At this time, since there is no need for the staff to load the goods at the first operation position, the system will automatically stop changing the displayed information and will resume modifying the order information only after calculating that the loaded cranes have passed the first operation position.

[0011] Preferably, the following steps are further included: Set the maximum number of empty cranes; When the signal from the first operation position is no longer received, start recording the number of cranes passing through the full cargo position, and subtract one from the recorded number of cranes to obtain the number of empty cranes; When the recorded number of empty cranes is greater than one, issue an empty crane prompt; When the recorded number of empty cranes is greater than the maximum number of empty cranes, issue an empty crane alarm and judge whether the crane currently located at the waiting position is not an empty crane; If it is judged that the crane currently located at the waiting position is an empty crane, calculate the number of empty cranes in the current buffer area, stop blocking the crane at the waiting position, and at the same time block the transmission signal of the second operation position and record 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 cranes, resume the transmission signal of the second operation position.

[0012] By adopting the above solution, during the production process, various situations may occur that cause the first operation 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 consecutive empty cars in the buffer area. When the number of empty cars reaches the maximum number of empty cars, the system will release all the empty cars when the first empty car in the buffer area reaches the waiting position, avoiding the blockage of the suspension chain by empty cars.

[0013] Preferably, the step "if it is determined that the crane at the waiting position is an empty car, calculate the number of empty cars in the current buffer area" further includes: After issuing an empty car prompt, calculate the position of the first empty car based on the number of cranes in the buffer area and the number of cranes passing through the waiting position; If the first empty car passes through the waiting position, subtract one from the number of empty cars and let the next empty car be the first empty car; If it is determined that the crane at the waiting position is an empty car, use the recorded number of empty cars as the number of empty cars in the buffer area.

[0014] By adopting the above solution, the system can accurately calculate the number and specific position of empty cars in the buffer area to ensure that all empty cars can be accurately released when releasing empty cars and that cranes loaded with items will not be released.

[0015] On the other hand, a suspension chain blockage intelligent alarm processing and management system provided by the present application adopts the following technical solutions: A suspension chain blockage intelligent alarm processing and management system includes the above-mentioned area division module, crane monitoring module, operation control module, automatic blocking module, and blockage alarm module; The area division module presets a suspension chain engineering drawing, and sets a buffer area, a pre-blocking position, a waiting position, and a full-load position on the suspension chain engineering drawing, and sets a buffer area, a pre-blocking position, a waiting position, and a full-load position on the transportation line; The crane monitoring module detects the number and position of cranes in the buffer area, and detects whether there are cranes at the first operation position, the second operation position, the pre-blocking position, the waiting position, and the full-load position; The operation control module is connected to the first operation position and the second operation position. When the first operation position transmits a signal, it blocks the crane arriving at the first operation position. When the first operation position stops transmitting a signal, it stops blocking the crane at the first operation position. When the second operation position transmits a signal, it releases one crane at the waiting position and re-detects whether there is a crane at the waiting position; The automatic blocking module is connected to the waiting position. When it detects that a crane arrives at the waiting position, it blocks the movement of the crane; The blockage alarm module is connected to the pre-blocking position and the full-load position. The blockage alarm module is preset with a set time. When the pre-blocking position detects a crane, the timing starts. When the timing reaches the set time, the blockage alarm module issues a pre-blocking alarm. When the full-load position detects a crane, the timing starts. When the timing reaches the set time, the blockage alarm module issues an overload alarm and stops blocking the crane at the waiting position. At the same time, it blocks the signal transmission of the blocking operation control module. When it detects that there is no crane in the buffer area, the timing is reset.

[0016] By adopting the above scheme, a buffer area is demarcated on the suspension chain. Before the next process, the staff stops the crane for loading at the first operation position. When the crane is about to enter the next process, it will first enter the buffer area, and the staff of the next process controls whether the crane can pass at the second operation position. If the release speed of the crane at the first operation position is too fast, or the staff at the second operation position processes the process too slowly, it will cause the cranes to pile up in the buffer area. When it piles up to the pre-blocking position, the system will judge whether the crane stays at the pre-blocking position through timing. If the crane stays at the pre-blocking position, it means that a blockage is about to occur, and the system will issue an alarm to notify the staff. When it piles up to the full-load position, the system will judge whether the crane stays at the full-load position through timing. If the crane stays at the full-load position, an alarm will be immediately issued and the cranes in the buffer area will be forcibly controlled to pass. At the same time, the signal transmission at the second operation position will be blocked to prevent the crane from being blocked again in a short time. This can effectively reduce the situation of crane blockage on the suspension chain and ensure the stable operation of the production line.

[0017] Preferably, the crane monitoring module sets RFID scanners at the pre-blocking position, waiting position and full-load position in the buffer area, and sets RFID cards on each crane. When the crane reaches the full-load position, the RFID scanner scans the RFID card and records the position of the crane. When the RFID card leaves the RFID scanner, it records that the crane enters the buffer area. When the crane reaches the pre-blocking position, the RFID scanner scans the RFID card and records the position of the crane. When the crane reaches the waiting position, the RFID scanner scans the RFID card and records the position of the crane. When the RFID card leaves the RFID scanner, it records that the crane leaves the buffer area.

[0018] 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 at the pre-blocking position, waiting position and full-load position.

[0019] Preferably, it further includes a data storage module and an order indication module; The data storage module receives and stores the input order information. The order information includes crane loading information. The crane loading information is sorted according to the order sequence, and a backup information table is established. The data storage module receives the input order completion information and deletes the crane loading information in the backup information table according to the order completion information; When the operation control module receives the signal of the first operation position, it transmits a first signal to the order indication module; When the blocking alarm module issues an overload alarm, the data storage module is controlled to stop modifying the order information and transmit a second signal to the order indication module; The order indication module calls the crane loading information of the data storage module, and the order indication module displays the sorted crane loading information. When the order indication module receives a first signal, it marks the frontmost crane loading information in 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 receives a second signal, the number of crane loading information in the spare information table is read. 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.

[0020] 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 gradually changes as the crane moves, which is convenient for the staff at the first operating position to load. After the buffer area is full, the system will not only release the cranes in the buffer area, but also record the loading information of the cranes on the released cranes. If the released cranes have their goods taken away in the next process, the corresponding records will be deleted through the order completion information. The remaining cranes that do not have time to take away the goods will move to the next process again after returning to the first operating position. At this time, since there is no need for staff to load at the first operating position, the system will automatically stop changing the displayed information. The modification of the order information will be resumed only after calculating that the loaded cranes have passed the first operating position.

[0021] Preferably, it also includes an empty vehicle alarm module; The operation control module stops transmitting an empty vehicle signal to the crane monitoring module when receiving the signal of the first operation position; After receiving the empty car signal, the crane monitoring module starts to record the number of cranes passing through the full warehouse, subtracts one from the recorded number of cranes to obtain the number of empty cars, and transmits the number of empty cars to the empty car alarm module; The empty car alarm module is set with a maximum number of empty cars. After the empty car alarm module receives the number of empty cars, when the received number of empty cars is greater than one, an empty car prompt is issued. When the number of empty cars is greater than the maximum number of empty cars, an empty car alarm is issued and it is determined whether the crane currently located in the waiting position is empty. If it is determined that the crane currently located in the waiting position is empty, the number of empty cars in the current buffer area is calculated, the crane located in the waiting position is stopped, and the second operating position transmission signal is blocked at the same time, and the number of cranes passing the waiting position is recorded. When the number of cranes passing the waiting position is equal to the calculated number of empty cars, the second operating position transmission signal is restored.

[0022] By adopting the above solution, during the production process, various situations may occur that cause 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 consecutive empty cars in the buffer area. When the number of empty cars reaches the maximum number of empty cars, the system will release all the empty cars when the first empty car in the buffer area reaches the waiting position, avoiding the blockage of the hanging chain by empty cars.

[0023] Preferably, after the empty car alarm module issues an empty car prompt, it calculates the position of the first empty car based on the number of overhead cranes in the buffer area and the number of overhead cranes passing through the waiting position. If the first empty car passes through the waiting position, the number of empty cars is decremented by one and the next empty car is taken as the first empty car. If it is determined that the overhead crane currently located at the waiting position is an empty car, the recorded number of empty cars is used as the number of empty cars in the buffer area.

[0024] By adopting the above solution, the system can accurately calculate the number and specific position of empty cars in the buffer area to ensure that all empty cars can be accurately released when releasing empty cars and that overhead cranes loaded with items will not be released.

[0025] In summary, the present invention has the following beneficial effects: 1. It will issue an alarm when the overhead crane may be blocked or is blocked, and will automatically dredge the overhead crane when it is blocked, which can effectively reduce the situation of the overhead crane being blocked on the hanging chain and ensure the stable operation of the production line.

[0029] The following is a further detailed description of the present application in conjunction with the attached Figure 1-2 drawings.

[0030] Embodiment 1. The embodiment of the present application discloses an intelligent alarm processing management method for hanging chain blockage. As Figure 1 shown, the specific steps are as follows: S100. Set a buffer zone 9, a pre-blocking position 94, a waiting position 93, and a full-load position 95 on the suspension chain. The pre-blocking 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 transportation line transportation direction. The full-load position 95 is located at the end of the buffer zone 9 along the transportation line transportation direction. The transportation line is respectively provided with a first operation position 91 and a second operation position 92 at positions in front of and behind the buffer zone 9. Set the maximum number of empty vehicles.

[0031] S101. Set up an order library to receive and store the input order information. The order information includes crane loading information. The crane loading information is sorted according to the order sequence number, and a spare information table is established.

[0032] S200. Display the sorted crane loading information.

[0033] S300. When the first operation position 91 transmits a signal, block the crane arriving at the first operation position 91.

[0034] S301. When the first operation position 91 stops transmitting the signal, stop blocking the crane located at the first operation position 91.

[0035] S302. When receiving the signal of the first operation position 91, mark the crane loading information at the forefront in the currently displayed crane loading information.

[0036] S303. When the signal of the first operation position 91 cannot be received, move the marked crane loading information from the order information to the spare information table.

[0037] S304. The order library receives the input order completion information and deletes the crane loading information in the spare information table according to the order completion information.

[0038] S305. When the signal of the first operation position 91 stops being received, start recording the number of cranes passing through the full-load position 95, and subtract one from the recorded number of cranes to obtain the number of empty vehicles.

[0039] S400. Detect the number of cranes and the positions of the cranes located in the buffer zone 9.

[0040] S401. Set RFID scanners at the pre-blocking position 94, the waiting position 93, and the full-load position 95 in the buffer zone 9.

[0041] S402. Set RFID cards on each crane.

[0042] S403. When the crane reaches the full-load position 95, the RFID scanner scans the RFID card and records the position of the crane. When the RFID card leaves the RFID scanner, record that the crane enters the buffer zone 9.

[0043] S404. When the crane reaches the pre-blocking position 94, the RFID scanner scans the RFID card and records the position of the crane.

[0044] S405. When the crane reaches the waiting position 93, the RFID scanner scans the RFID card and records the position of the crane. When the RFID card leaves the RFID scanner, it records that the crane has left the buffer area 9.

[0045] S500. When it is detected that the crane reaches the waiting position 93, block the movement of the crane.

[0046] S501. When the second operating position 92 transmits a signal, release one crane at the waiting position 93 and re-detect whether there is a crane at the waiting position 93.

[0047] S600. When a crane is detected at the pre-blocking position 94, start timing. When the timing reaches the set time, issue a pre-blocking alarm. Stop timing when no crane is detected at the pre-blocking position 94.

[0048] S601. When a crane is detected at the full load position 95, start timing. When the timing reaches the set time, issue an overload alarm and stop blocking the crane at the waiting position 93. At the same time, block the signal transmission of the second operating position 92. Stop timing when no crane is detected at the full load position 95.

[0049] S602. Stop modifying the order information and read the number of crane loading information in the backup information table.

[0050] S603. When the number of times of receiving and losing the signal of the first operating position 91 reaches the number of crane loading information in the backup information table, resume modifying the order information.

[0051] S604. When it is detected that there is no crane in the buffer area 9, reset the timing.

[0052] S700. When the recorded number of empty trucks is greater than one, issue an empty truck prompt. After issuing the empty truck prompt, calculate the position of the first empty truck according to the number of cranes in the buffer area 9 and the number of cranes passing through the waiting position 93.

[0053] S701. If the first empty truck passes through the waiting position 93, subtract one from the number of empty trucks and make the next empty truck the first empty truck.

[0054] S702. If it is determined that the crane currently at the waiting position 93 is an empty truck, use the recorded number of empty trucks as the number of empty trucks in the buffer area 9.

[0055] S703. When the recorded number of empty trucks is greater than the maximum number of empty trucks, issue an empty truck alarm and determine whether the crane currently at the waiting position 93 is not an empty truck.

[0056] S704. If it is determined that the crane at the waiting position 93 is an empty vehicle, calculate the number of empty vehicles in the current buffer 9, stop blocking the crane at the waiting position 93, and at the same time block the signal transmission of the second operation position 92 and record the number of cranes passing through the waiting position 93.

[0057] S705. When the number of cranes passing through the waiting position 93 is equal to the calculated number of empty vehicles, resume the signal transmission of the second operation position 92.

[0058] The implementation principle of the intelligent alarm processing and management system and method for suspension chain blockage in the embodiments of the present application is as follows: A buffer 9 is marked on the suspension chain. Before the next process, the staff stops the crane for loading at the first operation position 91. When the crane is about to enter the next process, it will first enter the buffer 9, and the staff of the next process controls whether the crane can pass at the second operation position 92. If the release speed of the crane at the first operation position 91 is too fast, or the processing speed of the staff at the second operation position 92 is too slow, it will cause the cranes to pile up in the buffer 9. When it piles up to the pre-blocking position 94, the system will judge whether the crane stays at the pre-blocking position 94 through timing. If the crane stays at the pre-blocking position 94, it means that a blockage is about to occur, and the system will issue an alarm to notify the staff. When it piles up to the full load position 95, the system will judge whether the crane stays at the full load position 95 through timing. If the crane stays at the full load position 95, an alarm will be immediately issued and the cranes in the buffer 9 will be forcibly controlled to pass, and at the same time, the signal transmission of the second operation position 92 will be blocked to avoid blocking the cranes from passing again in a short time. This can effectively reduce the occurrence of blockages of cranes on the suspension chain and ensure the stable operation of the production line.

[0059] Embodiment 2. The embodiments of the present application disclose an intelligent alarm processing and management system for suspension chain blockage, as Figure 2 shown, including a regional division module 1, a crane monitoring module 2, an operation control module 3, an automatic blocking module 4, a blockage alarm module 5, a data storage module 6, an order indication module 7, and an empty vehicle alarm module 8.

[0060] As Figure 1 and Figure 2 shown, the regional division module 1 presets a suspension chain engineering drawing, sets a buffer 9, a pre-blocking position 94, a waiting position 93, and a full load position 95 on the suspension chain engineering drawing, and sets a buffer 9, a pre-blocking position 94, a waiting position 93, and a full load position 95 on the transportation line.

[0061] As Figure 2As shown in the figure, the crane monitoring module 2 detects the number of cranes and their positions in the buffer area 9, and checks 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-load position 95. The crane monitoring module 2 sets RFID scanners at the pre-blocking position 94, the waiting position 93, and the full-load position 95 in the buffer area 9, and sets RFID cards on each crane. When a crane reaches the full-load position 95, the RFID scanner scans the RFID card and records the position of the crane. When the RFID card leaves the RFID scanner, it records that the crane enters the buffer area 9. When a crane reaches the pre-blocking position 94, the RFID scanner scans the RFID card and records the position of the crane. When a crane reaches the waiting position 93, the RFID scanner scans the RFID card and records the position of the crane. When the RFID card leaves the RFID scanner, it records that the crane leaves the buffer area 9. After receiving the empty-truck signal, the crane monitoring module 2 starts to record the number of cranes passing through the full-load position 95, subtracts one from the recorded number of cranes to obtain the number of empty trucks, and transmits the number of empty trucks to the empty-truck alarm module 8. 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 cranes at the pre-blocking position 94, the waiting position 93, and the full-load position 95.

[0062] As Figure 2 shown in the figure, 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 arriving 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 the signal, it stops blocking the crane at the first operation position 91 and transmits an empty-truck 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-checks whether there is a crane at the waiting position 93.

[0063] As Figure 2 shown in the figure, the automatic blocking module 4 is connected to the waiting position 93. When it detects that a crane reaches the waiting position 93, it blocks the movement of the crane.

[0064] As Figure 2 shown in the figure, the blockage alarm module 5 is connected to the pre-blocking position 94 and the full-load position 95. The blockage alarm module 5 has a preset time. When the pre-blocking position 94 detects a crane, it starts timing. When the timing reaches the preset time, the blockage alarm module 5 issues a pre-blocking alarm; when the full-load position 95 detects a crane, it starts timing. When the timing reaches the preset time, the blockage alarm module 5 issues an overload alarm, stops blocking the crane at the waiting position 93, blocks the signal transmission of the operation control module 3 at the same time, controls the data storage module 6 to stop modifying the order information, and transmits a second signal to the order indication module 7. When it detects that there is no crane in the buffer area 9, it resets the timing.

[0065] As Figure 2As shown, the data storage module 6 receives and stores the input order information. The order information includes the crane loading information. The crane loading information is sorted according to the order sequence number, and a backup information table is established. The data storage module 6 receives the input order completion information and deletes the crane loading information in the backup information table according to the order completion information.

[0066] As Figure 2 shown, the order indication module 7 calls the crane loading information of 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 among the currently displayed crane loading information. When the first signal is not received, it moves the marked crane loading information from the order information to the backup information table. When the order indication module 7 receives the second signal, it reads the quantity of the crane loading information in the backup information table. When the number of times of receiving and losing the first signal once reaches the quantity of the crane loading information in the backup information table, it resumes the modification of the order information.

[0067] Under normal circumstances, the system will display the information of the items that the current crane needs to load. The displayed information gradually changes as the crane moves, which is convenient for the staff at the first operation position 91 to load the vehicle. After the buffer area 9 is full, in addition to releasing the cranes in the buffer area 9, the system will also record the crane loading information of the released cranes. If the goods on the released crane are taken away in the next process, the corresponding record will be deleted through the order completion information. The remaining cranes that are too late to take away the goods will move to the next process again after returning to the first operation position 91. At this time, since there is no need for the staff to load the vehicle at the first operation position 91, the system will automatically stop changing the displayed information and will resume the modification of the order information only after calculating that the loaded cranes have passed the first operation position 91.

[0068] As Figure 2 shown, the empty vehicle alarm module 8 is set with a maximum number of empty vehicles. After the empty vehicle alarm module 8 receives the number of empty vehicles, when the received number of empty vehicles is greater than one, it issues an empty vehicle prompt, calculates the position of the first empty vehicle according to the number of cranes in the buffer area 9 and the number of cranes passing through the waiting position 93. If the first empty vehicle passes through the waiting position 93, the number of empty vehicles is reduced by one and the next empty vehicle is used as the first empty vehicle. If it is determined that the crane currently located at the waiting position 93 is an empty vehicle, 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, it issues an empty vehicle alarm and determines whether the crane currently located at the waiting position 93 is not an empty vehicle. If it is determined that the crane currently located at the waiting position 93 is an empty vehicle, it calculates the number of empty vehicles in the current buffer area 9, stops blocking the crane located at the waiting position 93, and at the same time blocks the transmission signal of the second operation position 92 and records the number of cranes passing through the waiting position 93. When the number of cranes passing through the waiting position 93 is equal to the calculated number of empty vehicles, the transmission signal of the second operation position 92 is restored.

Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
