[0034] Some embodiments of this application will now be described in more detail with reference to the accompanying drawings.
[0035] Figure 1 A schematic diagram of a test system 100 according to some embodiments of this application is shown. For example... Figure 1 As shown, the testing system 100 may include multiple work areas and automated guided vehicles (AGVs) capable of transporting between the multiple work areas. The AGVs may be configured to carry a mobile platform 101 (see...). Figure 3 The test vehicle 102, equipped with airbags and mounted on the mobile platform 101, is used for transportation between various work areas, thereby realizing an intelligent logistics system based on automated guided vehicles (AGVs) and effectively improving the transfer efficiency and automation level of the test vehicle 102 between multiple work areas.
[0036] To ensure efficient and reliable communication between multiple work areas and the Automated Guided Vehicle (AGV), the test system 100 is also equipped with a control system 110 (see...). Figure 2 The control system 110 can be configured to establish communication connections with the automated guided vehicle (AGV) and functional devices in multiple work areas, providing communication support for the overall coordinated operation of the system.
[0037] like Figure 2The diagram illustrates a schematic block diagram of a control system 110 according to some embodiments of this application. In some embodiments, the control system 110 may adopt a multi-control device architecture, where each control device is deployed in a corresponding work area and interacts with the functional devices within that work area. Simultaneously, the automated guided vehicle (AGV) can communicate with the corresponding control device to ensure the safe and efficient completion of transportation tasks. Furthermore, operators can also interact with the corresponding control device via a human-machine interface to achieve convenient control of the system. In some embodiments, the control system 110 may adopt a hierarchical "upper-lower" control architecture: including an upper-level control device 111 and lower-level control devices 112 distributed and installed in each work area, each equipped with a human-machine interface. The lower-level control devices 112 are configured to interact with the functional devices within their deployed work areas and further forward the interaction information to the upper-level control device 111. The upper-level control device 111 then implements specific control processes based on the interaction information from each lower-level control device 112, and, when necessary, the interaction information from the automated guided vehicle (AGV), ensuring the overall coordination and accuracy of the system's operation.
[0038] Continue to refer to Figure 1 The plurality of working areas may include a first working area, which may include a mobile platform turnover area A and a possible charging area for automated guided vehicles (AGVs). The charging area can provide power to the AGVs, enabling convenient charging during transport task breaks, ensuring their endurance, and preventing insufficient power from affecting the overall operating efficiency of the testing system 100.
[0039] The mobile platform turnover area A is the main functional area connecting the storage and scheduling of the mobile platform 101. To achieve this function, the mobile platform turnover area A may be configured with turnover equipment 115. Figure 3 An exemplary simplified schematic diagram of the turnover device 115 is shown. The turnover device 115 may include storage compartments for placing the mobile platform 101 and an adjustment mechanism (not shown) for adjusting the position of the storage compartments, wherein the adjustment mechanism is configured to meet the operational requirements of storing and retrieving the mobile platform 101 by adjusting the position, thereby improving the flexibility and efficiency of storing and retrieving the mobile platform 101.
[0040] In some embodiments, the storage compartment serves as a dedicated storage carrier for the mobile platform 101. A single storage compartment may correspond to a single mobile platform 101. The number of storage compartments may be increased or decreased, or the arrangement of the compartments may be adjusted (e.g., single-layer side-by-side arrangement or multi-layer stacked arrangement), depending on the space size of the mobile platform turnover area A and the actual storage requirements of the mobile platform 101, to adapt to the storage requirements in different scenarios and improve space utilization.
[0041] In some embodiments, the adjustment mechanism may include a drive component, a transmission component, and a positioning detection component, which work together to achieve precise position adjustment of the storage compartment. When the mobile platform 101 needs to be stored in the turnover equipment 115, the adjustment mechanism first confirms the initial position of the target storage compartment through the positioning detection component, and then the drive component provides power to drive the storage compartment to the designated position docked with the mobile platform 101 via the transmission component. After the mobile platform 101 is fully inserted into the storage compartment, the positioning detection component detects the platform position in real time, and the drive component, in cooperation with the transmission component, fine-tunes the position of the storage compartment to ensure that the mobile platform 101 is placed stably. Finally, the adjustment mechanism drives the storage compartment to reset to the initial storage position, completing the storage operation. When the mobile platform 101 needs to be retrieved from the turnover equipment 115, the adjustment mechanism first locks the target storage compartment through the positioning detection component. Driven by the drive component and transmission component, the target storage compartment is moved horizontally or vertically to the preset storage / retrieval position. After the automated guided vehicle (AGV) retrieves the mobile platform 101, the adjustment mechanism resets the storage compartment to its initial state, awaiting the next storage / retrieval operation. The entire process requires no manual intervention, achieving automation and precision in the storage and retrieval of the mobile platform 101. It should be understood that the construction scheme of the turnover equipment 115 can vary and is not limited to the current embodiment, as long as it can realize the storage and retrieval of the mobile platform 101.
[0042] Continue to refer to Figure 1 The plurality of working areas may include a second working area, which may include a test vehicle loading area B. The test vehicle loading area B may be equipped with a lifting device 120, which is configured to communicate with the control system 110 for adjusting lifting settings.
[0043] Figure 4An example diagram of the lifting equipment is shown. The lifting equipment 120 may include an adjustable fork arm mechanism 121, a multi-stage lifting column 122, and an automated guided vehicle (AGV) docking system (not shown). In some embodiments, the adjustable fork arm mechanism 121 may preferably adopt a double-fork arm symmetrical structure to ensure load balance. Furthermore, the adjustable fork arm mechanism 121 may integrate a telescopic mechanism and a locking device. The telescopic mechanism may use a built-in hydraulic cylinder or an electric push rod, capable of driving the fork arm length to achieve stepless adjustment within a preset range. The locking device may use a mechanical pin or a hydraulic self-locking valve to ensure that the fork arm does not shift under load, ensuring operational safety. In some embodiments, the multi-stage lifting column 122 may be configured to drive the adjustable fork arm mechanism to complete the lifting action, providing vertical position adjustment support for the transfer of the test vehicle 102. In some embodiments, the automated guided vehicle (AGV) docking system may be configured to realize the positioning docking of the lifting equipment 120 and the automated guided vehicle (AGV) and the transfer operation of the test vehicle 102. The automated guided vehicle (AGV) docking system may include a positioning module. The positioning module uses a combination of laser reflectors and AGV feature markings (such as QR codes) for navigation to meet preset positioning accuracy requirements and ensure that the docking process is accurate and efficient.
[0044] Continue to refer to Figure 1 The multiple working areas may include a third working area, which may include a test chamber T. The test chamber T, as an environmental chamber, can simulate various environmental conditions and supports high-temperature, low-temperature, and room-temperature detonation tests.
[0045] The third work area can, for example, be configured as a test work area without its own mobile platform 101. For this purpose, an automated guided vehicle (AGV) needs to retrieve and transport the corresponding mobile platform 101 from the mobile platform turnover area A to the third work area. This achieves efficient management and centralized scheduling of the mobile platform 101.
[0046] In addition, a first external test area C and a connecting area D between the test box T and the first external test area C are additionally set up in the third working area. This realizes an external test area attached to the test box T, enabling a greater number of test areas to be implemented in a compact space, thereby improving the comprehensive testing capability of the test system 100.
[0047] To conduct testing within the first external test area C, the Automated Guided Vehicle (AGV) can be positioned there and the test vehicle 102, along with the mobile platform 101, can be transferred to the first external test area C. To conduct testing within the test box T, the AGV can be positioned at the connection area D between the test box T and the first external test area C, and the test vehicle 102, along with the mobile platform 101, can be transferred to the connection area D. The mobile platform 101, positioned at the connection area D, along with the test vehicle 102, can be guided into the test box T by a traction system.
[0048] Furthermore, a second external test area E can be additionally provided in the third working area. In the illustrated embodiment, the second external test area E and the first external test area C can be arranged opposite each other on both sides of the test box T. In other words, the first external test area C can be located upstream of the test box T, while the second external test area E can be located downstream of the test box T. Thus, a "forward-backward" mode can be realized, allowing for selective detonation not only within the test box T but also in the first external test area C at room temperature without entering the test box T, or in the second external test area E after exiting the test box T. Of course, besides the "forward-backward" mode in this embodiment, it is also conceivable that in another embodiment, a "same-in, same-out" mode can be used, allowing selective detonation in the first external test area C at room temperature without entering the test box T, or in the first external test area C after exiting the test box T again. It should be noted that the dotted lines representing the corresponding external test areas are merely illustrative and do not limit the actual coverage area of the external test areas.
[0049] Next, refer to Figures 5 to 9 This application provides a detailed description of the third working area of a test system according to some embodiments.
[0050] like Figure 5-9As shown, the traction system for transporting the mobile platform 101 and the test vehicle 102 may include a support guide mechanism 2 and a traction mechanism. The support guide mechanism 2 extends from the test area C outside the first housing via the connecting area D into the test housing T and is configured to support and guide the mobile platform 101. The traction mechanism is configured to traction the mobile platform 101 along the support guide mechanism to move the mobile platform 101 carrying the test vehicle 102 into the test housing T. The traction mechanism may include a plurality of gear transmission mechanisms 3, which are spaced apart from each other and each has a rotatable output gear 34. The gear transmission mechanism 3 is configured to engage its output gear 34 with a rack 201 below the mobile platform 101 and to traction the mobile platform 101 along the support guide mechanism by rotating the output gear. A first portion of the gear transmission mechanism is arranged within the connecting area D, and a second portion of the gear transmission mechanism is arranged within the test housing T. The plurality of gear transmission mechanisms may each have a transmission housing that is connected to the output gear, and the traction mechanism includes a transmission shaft that passes through the respective transmission housing of each gear transmission mechanism and is configured to transmit the motion of the transmission shaft to the output gear of each gear transmission mechanism.
[0051] In some embodiments, the support and guidance mechanism 2 extends to a first external test area C that overlaps with the connection area D. Figure 6 The area shown in the dashed line (offset laterally from the connecting area D for visibility reasons) and the support guide mechanism 2 extend longitudinally over the first external test area C. Of course, in another embodiment, the first external test area C may also be adjacent to the connecting area D—especially when separated by a small distance. Furthermore, the support guide mechanism 2 extends to the second external test area E, which is opposite to and connected to the test box T with respect to the connecting area D. Figure 6 In the dashed area), the support and guide mechanism 2 extends longitudinally on the test area E outside the second box, wherein at least one third gear transmission mechanism 33 of the gear transmission mechanism 3 is arranged in the test area E outside the second box.
[0052] To ensure synchronous rotation of the output gears 34 in each gear transmission mechanism 3, each of the plurality of gear transmission mechanisms 3 has a transmission housing 35 that is driveably connected to the output gear 34, and the traction mechanism includes a drive shaft 4 that passes through the corresponding transmission housing 35 of each gear transmission mechanism 3 and is configured to transmit the motion of the drive shaft 4 to the output gear 34 of each gear transmission mechanism 3. The drive shaft 4 is constructed as a drive screw and has a length of approximately 8 m.
[0053] To achieve concentric positioning and prevent accuracy degradation due to concentricity deviation during operation, a constant velocity transmission mechanism 5 is arranged on the drive shaft 4 between every two second gear transmission mechanisms 32 inside the test chamber T. This constant velocity transmission mechanism 5 can achieve a 1:1 transmission ratio (this 1:1 constant velocity transmission mechanism 5 can also be called a 1:1 transmission reducer). The corresponding constant velocity transmission mechanism 5 is arranged at the center position between two adjacent second gear transmission mechanisms 32.
[0054] The traction mechanism includes a drive unit 6, which is located outside the test box T, for example, in the connection area D. This drive unit 6 drives the transmission shaft 4, allowing each gear transmission mechanism 3 to be centrally driven by the drive unit 6 at the box entrance via the transmission shaft 4. The drive unit 6 is a high-load servo motor with a power of 10kW and is capable of both forward and reverse rotation. The drive unit 6 can be configured as a servo motor in conjunction with the first gear transmission mechanism 31. The drive unit 6 transmits the rotational motion of its output shaft to the output gear 34 of the first gear transmission mechanism 31 and the transmission shaft 4 connected to the transmission box 35 via the transmission housing 35 of the first gear transmission mechanism 31, thereby driving the output gear 34 of all gear transmission mechanisms 3 to rotate.
[0055] The support and guiding mechanism 2 includes two parallel guide rails 21 extending longitudinally. In the respective outer regions of the housing, the support and guiding mechanism 2 also includes guide rail supports 22, on which the corresponding guide rails 21 are fixedly supported. On the upper surfaces of the two guide rails 21, protrusions 23 are respectively provided along the corresponding guide rails 21, and the corresponding protrusions 23 are configured to cooperate with the U-shaped sliding wheels of the mobile platform 101 to guide the movement of the mobile platform 101.
[0056] Continue to refer to Figure 1 The plurality of working areas may include a fourth working area, which may include an additional testing area F. The fourth working area may, for example, be configured as a testing working area with its own mobile platform 101. Furthermore, the plurality of working areas may include a fifth working area, which includes an abnormal sitting posture testing area G. The fifth working area may, for example, be configured as a testing working area without its own mobile platform 101. Therefore, the automated guided vehicle (AGV) needs to acquire and transport the corresponding mobile platform 101 from the mobile platform turnover area A to the fifth working area.
[0057] In some embodiments, to improve the positioning accuracy and feedback efficiency of automated guided vehicles (AGVs) in complex working environments, corresponding feature markers, such as QR codes, can be provided at designated locations in each working area for the AGV's self-positioning and location feedback. To this end, the AGV may have a recognition device for identifying the corresponding feature markers, such as QR codes, and a communication device for notifying the control system 110. The recognition device may be, for example, a camera. The communication device can establish a real-time connection with the control system 110 via a wireless local area network (WLAN) or industrial Ethernet, synchronously feeding back positioning data to the control system 110. This enables high-precision positioning of the AGV, real-time path correction, and location conflict warnings during multi-vehicle collaborative operations, significantly improving the stability and safety of the transportation process.
[0058] In some embodiments, different types of functional devices may be provided within the corresponding work area to perform different functional tasks. However, these functional devices may also constitute obstacles to the AGV's path during transportation in some cases. For example, camera equipment used to perform shooting tasks during testing and access control equipment within the corresponding work area. Therefore, the control system 110 can be configured to control the camera equipment and access control equipment to move to a safe position, thereby effectively avoiding the AGV and thus effectively preventing equipment damage and transportation interruption.
[0059] It should be noted that the configuration of the above-mentioned work area can be adjusted according to actual needs and is not limited to the content described in this embodiment.
[0060] Next, refer to Figures 10 to 13 This application provides a detailed description of exemplary flowcharts illustrating a scheduling method for a test system 100 according to some embodiments. It should be understood that the execution order of the steps involved in the scheduling method of this invention is not absolutely fixed and can be flexibly adjusted according to actual circumstances. Any adjustment to the above-mentioned step order, as long as it does not deviate from the core inventive concept of this application, should fall within the protection scope of the claims of this application.
[0061] Figure 10 The feeding scheduling process for testing system 100 is shown. For example... Figure 10As shown, the scheduling method may include the following steps: S100, receiving a loading instruction; S101, in response to the loading instruction, causing the automated guided vehicle (AGV) to move to the mobile platform turnover area A to obtain the mobile platform 101 and to move to the test vehicle loading area B to load the test vehicle 102 on the mobile platform 101; S102, receiving a feeding instruction, the feeding instruction indicating that the AGV should transport the test vehicle 102 to the target test area; S103, in response to receiving the feeding instruction, determining whether the obstacles along the way are in a safe position; S104, if the obstacles along the way are not in a safe position, causing the obstacles along the way to move to a safe position; S105, if the obstacles along the way are in a safe position, causing the AGV to start transporting the test vehicle 102 to the target test area.
[0062] In some embodiments, the loading instruction may be provided to the control system 110 by an operator. In some embodiments, the loading instruction may be implemented based on a human-machine interface device deployed in the test vehicle loading area B. The loading instruction may instruct the automated guided vehicle (AGV) to proceed to the mobile platform turnover area A to obtain the mobile platform 101, and then proceed to the test vehicle loading area B to load the test vehicle 102.
[0063] In some embodiments, the feeding instruction may be provided to the control system 110 by an operator. In some embodiments, the feeding instruction may be implemented based on a human-machine interface device deployed in a dispatch center or corresponding test work area. The feeding instruction instructs the automated guided vehicle (AGV) to transport the test vehicle 102 to the target test area.
[0064] Before the automated guided vehicle (AGV) starts feeding, in order to avoid safety accidents such as collisions and interference between the AGV and various objects in the transportation path from the source, and to improve the stability and safety of the feeding process, the scheduling method of this application can advantageously introduce a path obstacle detection process.
[0065] Upon receiving a feeding instruction, the control system 110 will automatically trigger a path obstacle detection process. To determine which path obstacles exist, the control system 110 can preferably identify potential obstacles in real time along a predetermined route from the current position of the automated guided vehicle (AGV) to the target test area. This can be achieved using a distributed identification system deployed within the test system 100 to identify obstacles that fall onto the predetermined route or pose a risk of interference with it. It should be understood that these path obstacles may include camera equipment within the test area, access control equipment (e.g., roller shutters) within the corresponding work area, other automated guided vehicles (AGVs) or operators in the corresponding passageways, etc.
[0066] In some embodiments, an object is identified as a "potential obstacle" when it meets any of the following conditions: the area where the static coordinates of the object overlap with the predetermined route exceeds a preset threshold; the dynamic trajectory of the object intersects with the predetermined route, and the time difference between the intersection point and the time when the automated guided vehicle (AGV) is expected to pass through the node is less than the safety buffer time; the object belongs to a high-risk category (such as operators or precision equipment), and even if it does not directly overlap with the predetermined route, it is less than the safety protection distance from the edge of the route.
[0067] Once the control system 110 identifies a potential obstacle, it can send a relocation instruction to move the obstacle to a safe location. In some embodiments, the distributed identification system continuously tracks the obstacle's relocation process, confirming whether it has moved as instructed through real-time location feedback. If the relocation stalls (e.g., a roller shutter door jammed, personnel not leaving in time), the system will escalate the alert method (e.g., repeat broadcast, send an alarm to the management terminal). In some embodiments, after the obstacle has been moved to the target location, the control system 110 can also confirm this by: the distributed identification system detecting that the distance between the obstacle's current coordinates and the predetermined route meets safety requirements and there is no risk of it re-entering the route.
[0068] To determine whether an Automated Guided Vehicle (AGV) has arrived at the target test area, a corresponding feature marker, such as a QR code, can be set at the target test area. Once the AGV has arrived at the target test area, the test vehicle 102, along with the possible mobile platform 101, can be transferred to the corresponding target test area. In some embodiments, if the AGV recognizes a first feature marker, it indicates that the AGV has arrived at the first external test area C within the third working area, which can then prompt the AGV to transfer the mobile platform 101, along with the test vehicle 102 on the mobile platform 101, to the first external test area C within the third working area. In some embodiments, if the AGV recognizes a second feature marker, it indicates that the AGV has arrived at the connecting area D within the third working area, which can then prompt the AGV to transfer the mobile platform 101, along with the test vehicle 102 on the mobile platform 101, to the connecting area D within the third working area. In some embodiments, if the AGV recognizes a fourth feature marker, it indicates that the AGV has arrived at the additional test area F within the fourth working area, which may prompt the AGV to move the test vehicle 102 without transferring the mobile platform 101 to the additional test area F within the fourth working area. In some embodiments, if the AGV recognizes a fifth feature marker, it indicates that the AGV has arrived at the abnormal sitting posture test area G within the fifth working area, which may prompt the AGV to move the mobile platform 101 together with the test vehicle 102 on the mobile platform 101 to the abnormal sitting posture test area G within the fifth working area.
[0069] Figure 11 The return scheduling process for testing system 100 is shown. For example... Figure 11 As shown, the scheduling method may include the following steps: S106, receiving a return command; S107, in response to receiving the return command, determining whether the obstacle is in a safe position; S108, if the obstacle is not in a safe position, causing the obstacle to move to a safe position; S109, if the obstacle is in a safe position, causing the automated guided vehicle (AGV) to move to the first working area or the second working area; S110, in response to the AGV recognizing the sixth or seventh feature marker, generating a completion command; S111, in response to the completion command, causing the obstacle to return to the set state.
[0070] In some embodiments, the return instruction may be provided to the control system 110 by an operator. In some embodiments, the return instruction may be implemented based on a human-machine interface device deployed in the corresponding test work area. The return instruction instructs the automated guided vehicle (AGV) to return to a non-test work area, such as a first work area or a second work area.
[0071] Before the automated guided vehicle (AGV) begins its return journey, in order to prevent safety accidents such as collisions and interference between the AGV and various objects on the return path, the scheduling method of this application can advantageously introduce a path obstacle detection process.
[0072] Upon receiving a return command, the control system 110 will automatically trigger the obstacle detection process. To determine which obstacles exist, the control system 110 can preferably identify potential obstacles in real time along a predetermined route from the current position of the automated guided vehicle (AGV) to its destination. This can be achieved using a distributed identification system deployed within the testing system 100 to identify obstacles that fall onto the predetermined route or pose a risk of interference with it. It should be understood that these obstacles may include camera equipment within the testing area, access control equipment (e.g., roller shutters) within the corresponding work area, other AGVs or operators on the corresponding passageways, etc. It should be understood that the obstacle detection process during material feeding is also applicable to the obstacle detection process during return, and will not be elaborated upon here.
[0073] Advantageously, once the AGV recognizes the sixth feature marker assigned to the first work area or the seventh feature marker assigned to the second work area, it indicates that the AGV has successfully arrived at its destination. The control system 110 can generate a completion command, thereby causing obstacles along the way to return to their set state or releasing the movement restrictions on the obstacles.
[0074] Figure 12 The charging scheduling process is illustrated. For example... Figure 12 As shown, the scheduling method may further include the following steps: S112, in response to receiving a charging command, determining whether the automated guided vehicle (AGV) carries a mobile platform 101; S113, in response to the AGV carrying a mobile platform 101, causing the AGV to move to the turnover equipment in the first working area to store the mobile platform 101 in the storage compartment of the turnover equipment; S114, in response to the AGV not carrying a mobile platform 101, causing the AGV to move to the charging area in the first working area.
[0075] In some embodiments, a charging command may be provided to the control system 110 by an operator. In some embodiments, the charging command may be implemented based on a human-machine interface device deployed in the corresponding work area. In some embodiments, the charging command may be automatically triggered based on the battery charge parameters of the automated guided vehicle (AGV) falling below a predetermined threshold.
[0076] Since some test areas are equipped with their own mobile platform 101, while others are not, different scheduling procedures can be implemented depending on whether the mobile platform 101 is present before charging begins. If the AGV carries the mobile platform 101, it can be moved to the turnover equipment in the first work area to store the mobile platform 101 in its storage compartment before proceeding to the charging area. If the AGV does not carry the mobile platform 101, it can be directly moved to the charging area in the first work area.
[0077] Figure 13 The material handling and scheduling process is shown. For example... Figure 13 As shown, the scheduling method may further include the following steps: S115, receiving a material retrieval instruction, the material retrieval instruction instructing the automated guided vehicle (AGV) to proceed to the target test area to retrieve the test vehicle 102; S116, in response to receiving the material retrieval instruction, determining whether the AGV carries a mobile platform 101; S117, if the material retrieval instruction instructs the AGV to proceed to the target test area within the third or fifth work area and the AGV carries a mobile platform 101, causing the AGV to move to the turnover equipment in the first work area to store the mobile platform 101 in the storage compartment of the turnover equipment; S118, if the material retrieval instruction instructs the AGV to proceed to the target test area within the fourth work area and the AGV does not carry a mobile platform 101, causing the AGV to move to the turnover equipment in the first work area to retrieve the mobile platform 101 from the turnover equipment.
[0078] In some embodiments, the material handling instruction may be provided to the control system 110 by an operator. In some embodiments, the material handling instruction may be implemented based on a human-machine interface device deployed in the corresponding work area.
[0079] Since some test areas are equipped with their own mobile platform 101, such as those in the third or fifth working areas, while others are not equipped with their own mobile platform 101, such as those in the fourth working area, different scheduling processes can be introduced depending on whether the mobile platform 101 is carried before material retrieval begins. If the material retrieval instruction indicates that the target test area does not have its own mobile platform 101 and the AGV carries the mobile platform 101, the AGV can be prompted to move to the turnover equipment in the first working area to store the mobile platform 101 in the storage compartment of the turnover equipment before proceeding to the target test area for material retrieval. If the material retrieval instruction indicates that the target test area does not have its own mobile platform 101 and the AGV does not carry the mobile platform 101, the AGV can be prompted to go directly to the target test area for material retrieval. If the material retrieval instruction indicates that the AGV should proceed to the target test area with its own mobile platform 101 and the AGV is not carrying the mobile platform 101, the AGV can be moved to the turnover equipment in the first work area to retrieve the mobile platform 101 from its storage compartment, and then proceed to the target test area with the mobile platform 101 for material retrieval. If the material retrieval instruction indicates that the AGV should proceed to the target test area with its own mobile platform 101 and the AGV is carrying the mobile platform 101, the AGV can proceed directly to the target test area for material retrieval. This allows the scheduling system to be efficiently adapted to the test system 100, which has various types of test areas.
[0080] To determine whether an Automated Guided Vehicle (AGV) has arrived at the target test area, a corresponding feature marker, such as a QR code, can be set at the target test area. Once the AGV has arrived at the target test area, the test vehicle 102, along with a possible mobile platform 101, can be transferred from the target test area to the AGV. In some embodiments, if the AGV recognizes a first feature marker, it indicates that the AGV has arrived at the first external test area C within the third working area, which can then prompt the AGV to retrieve the mobile platform 101 along with the test vehicle 102 on the mobile platform 101 from the first external test area C within the third working area. In some embodiments, if the AGV recognizes a second feature marker, it indicates that the AGV has arrived at the connecting area D within the third working area, which can then prompt the AGV to retrieve the mobile platform 101 along with the test vehicle 102 on the mobile platform 101 from the connecting area D within the third working area. In some embodiments, if the Automated Guided Vehicle (AGV) identifies a third feature marker, it indicates that the AGV has arrived at the second external test area E within the third working area, which may cause the AGV to retrieve the mobile platform 101 along with the test vehicle 102 on the mobile platform 101 from the second external test area E within the third working area. In some embodiments, if the AGV identifies a fourth feature marker, it indicates that the AGV has arrived at the additional test area F within the fourth working area, which may cause the AGV to retrieve the test vehicle 102 from the additional test area F within the fourth working area. In some embodiments, if the AGV identifies a fifth feature marker, it indicates that the AGV has arrived at the abnormal sitting posture test area G within the fifth working area, which may cause the AGV to retrieve the mobile platform 101 along with the test vehicle 102 on the mobile platform 101 from the abnormal sitting posture test area G within the fifth working area.
[0081] In some embodiments, the scheduling method may further include: in response to receiving a material handling instruction or identifying a corresponding feature marker, determining whether a path obstacle is in a safe position; if the path obstacle is not in a safe position, causing the path obstacle to move to a safe position; if the path obstacle is in a safe position, causing the automated guided vehicle (AGV) to move to a second working area. This ensures reliable path obstacle detection during the material handling return process. Advantageously, once the AGV identifies a sixth feature marker assigned to the first working area or a seventh feature marker assigned to the second working area, it indicates that the AGV has successfully arrived at its destination. The control system 110 can generate a completion instruction, thereby causing the path obstacle to return to a set state or releasing the movement restriction of the path obstacle.
