Description

Technical Field

[0001] This invention relates to the technical field of vehicle depot area scheduling, and more specifically, to a vehicle planar depot area scheduling system and method. Background Technology

[0002] The scheduling of vehicle storage areas is a crucial part of the manufacturing process, and an excellent scheduling system is essential for smooth production. Currently, many vehicle storage warehouses use either manual scheduling or a combination of PLC logic and manual scheduling. Manual scheduling requires manual calculation of vehicle departure order and on-site inspection of each lane's status before scheduling vehicles, a complex process requiring at least two people. Using a combination of PLC logic and manual algorithms for vehicle departure scheduling also requires manual calculation of the departure order and on-site scheduling. These methods are not only inefficient but also prone to errors, leading to incorrect parts assembly during vehicle assembly, and these errors are difficult to troubleshoot. Therefore, it is of great importance to implement safe power-off and power-on controls for high-voltage components in vehicles to protect the safety of maintenance personnel. Summary of the Invention

[0003] This invention provides a vehicle planar storage area scheduling system and method, which solves the problems of low efficiency, error susceptibility and difficulty in troubleshooting that existing automobile manufacturers require manual scheduling in their vehicle storage planar storage areas. This system can improve the efficiency and automation level of vehicle scheduling and reduce scheduling errors.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A vehicle horizontal warehouse area scheduling system includes: a PCS server, a scheduling PLC, a field control PLC, an RFID reader, and a transfer machine;

[0006] The PCS server is connected to the scheduling PLC. The PCS server obtains the entry and exit data of vehicles in the warehouse area in real time, and performs route calculation based on the entry and exit data and production plan to determine the entry and exit route.

[0007] The scheduling PLC is communicatively connected to the field PLC, and the field control PLC is signal-connected to the RFID reader and the transfer machine, respectively.

[0008] RFID readers are installed at the entrances and exits of each lane in the flat storage area, and electronic tags are installed on the vehicles.

[0009] After the vehicle enters the routing area, the on-site control PLC reads the electronic tag on the vehicle through the RFID reader to obtain vehicle information and vehicle destination.

[0010] The dispatching PLC sends the entry / exit lane number to the field control PLC based on the vehicle entry / exit route and the vehicle destination. The field control PLC then controls the transfer machine to send the vehicle to the lane entrance / exit corresponding to the entry / exit lane number.

[0011] Preferably, it also includes: an operating terminal;

[0012] The operating terminal is connected to the field control PLC signal. The operating terminal is equipped with a human-machine interface. In manual mode, the user selects the vehicle entry / exit lane number through the human-machine interface.

[0013] Preferably, it also includes: a positioning sensor;

[0014] The positioning sensor is installed at each lane entrance and exit and at each lane number corresponding position in the flat storage area. The positioning sensor is connected to the field PLC signal, and the field PLC determines whether the vehicle is in the set position based on the detection signal of the positioning sensor.

[0015] Preferably, the positioning sensor is a photoelectric switch.

[0016] The present invention also provides a vehicle horizontal parking area scheduling method, using the above-mentioned scheduling system, including:

[0017] The flat storage area is divided into a coarse sorting area and a fine sorting area;

[0018] Set up entry and exit rules for the route. The fine-schedule area is set to automatically enter and exit vehicles according to the set route strategy. The fine-schedule area enters and exits vehicles according to the first-in-first-out (FIFO) entry and exit rules, and makes the vehicle entry and exit correspond to the production plan.

[0019] The information on vehicles entering and leaving the warehouse and their destinations is obtained and reported through the on-site control PLC.

[0020] After receiving the entry / exit lane number sent by the scheduling PLC, the vehicle is moved to the lane entrance / exit corresponding to the entry / exit lane number according to the routing entry / exit rules.

[0021] Preferred options also include:

[0022] When a vehicle enters the storage area, a position sensor detects whether the vehicle has arrived at the entrance. If so, the RFID reader is controlled to scan the vehicle's electronic tag to obtain vehicle information and its destination.

[0023] Record current vehicle information. If the user selects manual mode as the current mode, control the transfer machine to guide the vehicle into the parking space based on the vehicle parking lane number manually entered by the user.

[0024] If the user selects the current mode as automatic mode, the system receives the entry information calculated by the PCS server and controls the transfer machine to automatically enter the parking space for the vehicle.

[0025] Preferred options also include:

[0026] When a vehicle departs from the warehouse area, a trigger signal indicating that the transport equipment is ready to receive the vehicle is obtained.

[0027] If the current mode is manual mode, manually select the exit lane number and control the transfer machine to pick up the vehicle in the corresponding lane according to the exit lane number;

[0028] If the current mode is automatic mode, it is determined whether the exit lane number is in the coarse scheduling area or the fine scheduling area. If it is in the fine scheduling area, the current exit lane is automatically calculated according to the first-in-first-out routing rule to control the vehicle to exit the parking space automatically.

[0029] Preferred options also include:

[0030] Obtain information on vehicles that require freezing. If a vehicle is found to be subject to freezing before entering the route area, transport the vehicle back to the route.

[0031] Upon receiving the unfreeze command for the corresponding vehicle, the vehicle will be unfrozen and allowed to be dispatched online normally.

[0032] Preferred options also include:

[0033] When a vehicle needs to be detained for management purposes, a detention alarm time is set for the vehicle, and the vehicle is detained according to the detention alarm time.

[0034] The system acquires real-time data on vehicles stranded in the storage area and determines whether the vehicle has reached the stranding alarm time. If so, it issues a stranding alarm.

[0035] Preferred options also include:

[0036] If the on-site control PLC does not receive the issued entry / exit lane number within the set time threshold, it will prompt manual intervention to switch to manual mode.

[0037] This invention provides a vehicle scheduling system and method for a flat parking area. It combines RFID reader / writer stations installed at the entrances and exits of each lane in the flat parking area with electronic tags installed on vehicles to locate them in real time and a scheduling system to achieve automatic vehicle scheduling in the flat parking area. This solves the problems of low efficiency, error susceptibility and difficulty in troubleshooting that existing automobile manufacturers require manual scheduling in flat parking areas. It can improve the efficiency and automation level of vehicle scheduling and reduce scheduling errors. Attached Figure Description

[0038] To more clearly illustrate the specific embodiments of the present invention, the accompanying drawings used in the embodiments will be briefly described below.

[0039] Figure 1 This is a schematic diagram of a vehicle horizontal depot area scheduling system provided by the present invention.

[0040] Figure 2 This is a schematic diagram of a vehicle planar depot scheduling method provided by the present invention.

[0041] Figure 3 This is a schematic diagram of the distribution of the storage area provided in an embodiment of the present invention. Detailed Implementation

[0042] To enable those skilled in the art to better understand the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and implementation methods.

[0043] To address the current issues of low efficiency, error-proneness, and difficulty in troubleshooting vehicle scheduling in flat storage areas of automobile manufacturing enterprises, which require manual scheduling, this invention provides a vehicle flat storage area scheduling system and method. This system solves the problems of low efficiency, error-proneness, and difficulty in troubleshooting existing vehicle scheduling in flat storage areas of automobile manufacturing enterprises, and can improve the efficiency and automation level of vehicle scheduling, and reduce scheduling errors.

[0044] like Figure 1 As shown, a vehicle horizontal storage area scheduling system includes: a PCS server, a scheduling PLC, a field control PLC, an RFID reader, and a transfer machine. The PCS server is communicatively connected to the scheduling PLC. The PCS server acquires real-time vehicle entry and exit data for the storage area and performs route calculations based on the entry and exit data and production plans to determine the entry and exit routes. The scheduling PLC is communicatively connected to the field PLC, and the field control PLC is signal-connected to both the RFID reader and the transfer machine. RFID readers are installed at the entrances and exits of each lane in the horizontal storage area, and electronic tags are affixed to the vehicles. After a vehicle enters the routing area, the field control PLC reads the electronic tags on the vehicle using the RFID reader to obtain vehicle information and its destination. The scheduling PLC sends entry / exit lane numbers to the field control PLC based on the entry / exit routes and vehicle destinations. The field control PLC then controls the transfer machine to deliver the vehicle to the lane entrance / exit corresponding to the entry / exit lane number.

[0045] Specifically, after a vehicle enters the routing area, its electronic tag is read to obtain vehicle information and determine its destination. The PCS server performs routing calculations to determine the entry and exit routes. The dispatch PLC transmits the lane number to the field control PLC, which then controls the transfer machine to transport the vehicle to the corresponding transport lane.

[0046] The vehicle entry procedure in the warehouse area is as follows:

[0047] 1) At the vehicle entrance transfer machine, the sensor detects that the vehicle has arrived, and the RFID reader reads the tag.

[0048] 2) Record the current vehicle information and wait for the lane entry information calculated by the dispatch system server.

[0049] 3) If the user selects manual mode, the system will wait for the user to manually enter the vehicle's entry lane number. If the user selects automatic mode, the system will control the vehicle's entry according to the set routing rules.

[0050] 4) The on-site control PLC receives lane information sent by the dispatch PLC and controls the transfer machine to send the vehicle into the designated lane.

[0051] The vehicle dispatch procedure in the warehouse area is as follows:

[0052] 1) Triggering condition: The transport equipment is ready to receive the vehicle.

[0053] 2) When the monitoring PLC receives the ready signal of the transport equipment, if the current mode is manual, the lane number is manually selected.

[0054] 3) If the current location is in automatic mode, the dispatch PLC automatically calculates the current exit lane according to the set routing rules. The field control PLC receives the lane number issued by the dispatch PLC and controls the transfer machine to go to the corresponding lane to pick up the vehicle.

[0055] The system also includes: an operation terminal; the operation terminal is connected to the field control PLC signal, and the operation terminal is equipped with a human-machine interface. In manual mode, the user selects the vehicle entry / exit lane number through the human-machine interface.

[0056] Furthermore, the operating terminal is a computer or a monitor.

[0057] The system also includes: a position sensor; the position sensor is installed at each lane entrance and exit and at the corresponding position of each lane number in the flat storage area. The position sensor is connected to the field PLC signal, and the field PLC determines whether the vehicle is in the set position based on the detection signal of the position sensor.

[0058] Furthermore, the positioning sensor employs a photoelectric switch.

[0059] As can be seen, the present invention provides a vehicle horizontal storage area scheduling system, which combines RFID reading and writing stations installed at the entrances and exits of each lane in the horizontal storage area with electronic tags installed on vehicles to locate the vehicles in real time and a scheduling system to achieve automatic vehicle scheduling in the horizontal storage area. This solves the problems of low efficiency, error susceptibility and difficulty in troubleshooting that existing automobile manufacturers require manual scheduling in the horizontal storage area of ​​automobiles. It can improve the efficiency and automation level of vehicle scheduling and reduce scheduling errors.

[0060] Accordingly, such as Figure 2 As shown, the present invention also provides a vehicle planar depot area scheduling method, using the above-mentioned scheduling system, including:

[0061] S1: Set the flat storage area into a coarse sorting area and a fine sorting area.

[0062] S2: Set the entry and exit rules for the route. The fine-schedule area is set to automatically enter and exit vehicles according to the set route strategy. The fine-schedule area enters and exits vehicles according to the first-in-first-out entry and exit rules, and makes the entry and exit of vehicles correspond to the production plan.

[0063] S3: Obtain vehicle information and destination for vehicles entering and leaving the warehouse through the on-site control PLC and report it.

[0064] S4: After receiving the entry / exit lane number sent by the scheduling PLC, the vehicle is moved to the lane entrance / exit corresponding to the entry / exit lane number according to the routing entry / exit rules.

[0065] In one embodiment, the planar storage area is as follows: Figure 3 As shown, the warehouse area is divided into a coarse sorting area, a fine sorting area 1, and a fine sorting area 2.

[0066] Coarse routing in the entry area: When a vehicle arrives at the entrance rotary table, a route calculation is performed. Based on the calculation result, the system determines which transfer machine the vehicle should go to next and pre-positions itself in the storage area. Specific routing and scheduling strategies can be flexibly selected within the scheduling system. When a vehicle arrives at transfer machine 1 or 2, the GATES system sends the lane number information to the field control PLC for scheduling. Transfer machines 1 and 2 autonomously configure their schedulable areas; these areas cannot overlap. The lane number calculation order for transfer machine 1 is from 1 to 12, and for transfer machine 2, it is from 12 to 1. During the interaction between the field control PLC and the higher-level scheduling PLC, the field control PLC informs the higher-level scheduling PLC of the transfer machine number that needs to be requested for scheduling.

[0067] Coarse-grained routing: The dispatching system sends track numbers to the dispatching machines based on the idle status of dispatching machines 1 and 2 to facilitate vehicle departure. Specific dispatching strategies can be flexibly selected within the dispatching system. Dispatching machines 1 and 2 autonomously configure their dispatchable areas, which cannot overlap. The track number calculation sequence for dispatching machine 1 is from 1 to 12, while the track number calculation sequence for dispatching machine 2 is from 12 to 1. During the interaction between the upper and lower levels, the field control PLC informs the upper-level dispatching PLC of the dispatching machine number that needs to be requested for dispatch.

[0068] The exit route of Zone 1 of the fine-tuning system: One RFID station is added to the exit transfer machine of Zone 1 of the fine-tuning system to receive vehicle exit instructions from the fine-tuning system and verify vehicle information; The exit transfer machine of Zone 1 of the fine-tuning system uses one RFID station to receive vehicle exit instructions from the fine-tuning system and verify vehicle information.

[0069] The inbound / outbound principle is First-In, First-Out (FIFO). Transfer machines 1 and 2 can autonomously configure their schedulable areas, but their schedulable areas cannot overlap. Transfer machine 1's lane number is calculated from 1 to 13, while transfer machine 2's lane number is calculated from 13 to 1. During the interaction between the control and dispatching PLCs, the field control PLC informs the dispatching PLC of the transfer machine number that needs to be requested for dispatch.

[0070] Entry route for Zone 2: The transfer station at the entrance of Zone 2 will have one additional RFID station (shared with the RFID station at the exit of Zone 1) to accept vehicles from Zone 1, read and verify vehicle information, and request an entry route from the upper level.

[0071] The inbound / outbound principle is First-In, First-Out (FIFO). Transfer machines 1 and 2 can autonomously configure their schedulable areas, but their schedulable areas cannot overlap. Transfer machine 1's lane number is calculated from 1 to 9, and transfer machine 2's lane number is calculated from 9 to 1. During the interaction between the control and dispatching PLCs, the field control PLC informs the dispatching PLC of the transfer machine number that needs to be requested for dispatch.

[0072] Outbound route for Zone 2: Two RFID stations are added to the exit transfer machines in Zone 2 to receive vehicle exit commands from the zone and verify vehicle information. The entry and exit principle is First-In, First-Out (FIFO). Transfer machines 1 and 2 can autonomously configure their dispatchable areas, but their dispatchable areas cannot overlap. Transfer machine 1's lane number is calculated from 1 to 9, and transfer machine 2's lane number is calculated from 9 to 1. During the communication between the control PLC and the dispatch PLC, the field control PLC informs the dispatch PLC of the transfer machine number that needs to be requested for dispatch.

[0073] Routing at the main exit of the second-stage sorting station (rotary roller bed): One RFID station is added to the main exit of the second-stage sorting station (rotary roller bed) to read vehicle information and determine the rotation direction of the rotary roller bed. When the rotary roller bed is not currently occupied, it requests the rotation direction from the upper control. The upper control compares the passing information of the current station and the published station to obtain the information of the next vehicle that should enter the station, and determines which transfer machine exit of the second-stage sorting station the vehicle will exit from, ultimately determining the rotation direction of the rotary roller bed.

[0074] The method also includes:

[0075] When a vehicle enters the storage area, a position sensor detects whether the vehicle has arrived at the entrance. If so, the RFID reader is controlled to scan the vehicle's electronic tag to obtain vehicle information and its destination.

[0076] Record current vehicle information. If the user selects manual mode as the current mode, control the transfer machine to guide the vehicle into the parking space based on the vehicle parking lane number manually entered by the user.

[0077] If the user selects the current mode as automatic mode, the system receives the entry information calculated by the PCS server and controls the transfer machine to automatically enter the parking space for the vehicle.

[0078] In practical applications, the dispatching route entry process mainly describes how, after a vehicle enters the routing area, its information is obtained by reading its tag to determine its destination. The lane number is then transmitted to the equipment controller, which transports the vehicle to the corresponding transport lane. Route settings are normally automatic, but a manual mode is also available, allowing manual assignment of vehicles to specific lanes. If the equipment controller does not receive the assigned lane number, an alarm will sound, requiring manual intervention. Manual operation is only permitted by authorized personnel, and operation information can be found within the dispatching system. Route entry rules: Each lane should be configured with corresponding features to push the appropriate vehicles to the designated lane.

[0079] The method also includes:

[0080] When a vehicle departs from the warehouse area, a trigger signal indicating that the transport equipment is ready to receive the vehicle is obtained.

[0081] If the current mode is manual mode, manually select the exit lane number and control the transfer machine to pick up the vehicle in the corresponding lane according to the exit lane number;

[0082] If the current mode is automatic mode, it is determined whether the exit lane number is in the coarse scheduling area or the fine scheduling area. If it is in the fine scheduling area, the current exit lane is automatically calculated according to the first-in-first-out routing rule to control the vehicle to exit the parking space automatically.

[0083] In practical applications, the dispatching route exit process mainly describes how, when a vehicle exits, it needs to read the tag to obtain vehicle information to determine its destination, and then transmit the lane number to the equipment controller. The controller then moves the transfer machine to the corresponding exit to receive the vehicle. Routing is normally set automatically, but a manual mode is also possible, where vehicles can be manually assigned to specific lanes. If the equipment controller does not receive the transmitted lane number, it will trigger an alarm, requiring manual intervention. Manual operation is only permitted by authorized personnel, and operation information can be found in the dispatching system. Route exit rules: When a vehicle exits, its information needs to be compared with the corresponding information in the system's production plan.

[0084] The method also includes: obtaining information on vehicles that need to be frozen; if a vehicle is found to be a vehicle to be frozen before entering the route area, the vehicle is transported back to the route; after receiving an unfreezing instruction from the corresponding vehicle, the vehicle is unfrozen and the corresponding vehicle is allowed to be scheduled online normally.

[0085] In practical applications, the vehicle freezing and unfreezing process is as follows: Vehicle information is entered before entering the routing area (AVI) to be frozen. When a vehicle arrives at this AVI, it will be transported to the return route. After production personnel resolve the production issues, the vehicle will be unfrozen. If an anomaly is detected in a vehicle before entering the routing area, manual freezing is required to prevent the vehicle from going online and causing line stoppages. Vehicles without submitted freezing information will not be transported to the return route by the dispatch system.

[0086] The method also includes: setting a vehicle detention alarm time when the vehicle needs to be detained, and detaining the vehicle according to the detention alarm time; acquiring the vehicles detained in the warehouse area in real time, determining whether the vehicle has reached the detention alarm time, and if so, issuing a detention alarm.

[0087] In practical applications, the delayed vehicle alarm prompt mainly describes the operational procedure for triggering a delayed vehicle alarm. When a new vehicle model requires delayed vehicle management, it is necessary to maintain the delayed vehicle alarm time for that model. Reports can be used to query and edit the delayed vehicle alarm time.

[0088] The method also includes: if the field control PLC does not receive the issued entry / exit lane number within a set time threshold, it will prompt manual intervention to enter manual mode.

[0089] As can be seen, the present invention provides a vehicle scheduling method for a flat warehouse area. It utilizes RFID reading and writing stations installed at the entrances and exits of each lane in the flat warehouse area and an electronic tag installed on the vehicle to locate the vehicle in real time, combined with a scheduling system, to achieve automatic vehicle scheduling in the flat warehouse area. This solves the problems of low efficiency, error susceptibility, and difficulty in troubleshooting that exist in the current flat warehouse area scheduling of automobiles by automobile manufacturers. It can improve the efficiency and automation level of vehicle scheduling and reduce scheduling errors.

[0090] The structure, features, and effects of the present invention have been described in detail above with reference to the embodiments shown in the figures. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, shall be within the protection scope of the present invention as long as they do not exceed the spirit covered by the specification and figures.
