Description

Technical Field

[0001] The present invention belongs to the technical field of robot intelligent systems, and in particular relates to an optical communication enhanced robot intelligent collaboration system. Background Art

[0002] An optical communication robot is a robot that uses optical communication technology for signal transmission. By installing optical communication devices on mobile and fixed equipment, point-to-point information interaction can be achieved, with high communication efficiency and flexibility. Among them, the optical communication AGV cart is a common optical communication enhanced robot. The optical communication AGV cart mainly works through optical beacons and light receiving devices installed in the factory. These devices can quickly "receive" route instructions, handling tasks, and adjust positions in real time. The whole process is very accurate and fast.

[0003] In the existing technology, most optical communication AGVs mainly use a single point-to-point optical communication method for operation control. Although this control method can control the route instruction reception and transportation movement process of the optical communication AGV, due to the complex actual environment, when the sensor is dirty, faulty, or there is a conflict between multiple equipment routes, the optical communication AGV is prone to stop or collide, resulting in poor operation intelligence, flexibility and reliability of the optical communication AGV.

[0004] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0005] The purpose of the present invention is to provide an optical communication enhanced robot intelligent collaboration system, which can improve the operation intelligence, flexibility and reliability of optical communication AGV vehicles.

[0006] In order to achieve the above object, a specific embodiment of the present invention provides the following technical solutions:

[0007] An optical communication enhanced robot intelligent collaboration system includes: an intelligent decision-making and planning module, a collaborative sensing module and an early warning and error correction module. The intelligent decision-making and planning module is used to intelligently plan the travel path of the optical communication robot; the collaborative sensing module is used to collect data and convert information from sensors configured for the optical communication robot; and the early warning and error correction module is used to perform error correction and early warning processing on the collaborative sensing module.

[0008] In one or more embodiments of the present invention, the intelligent decision-making planning module is composed of an intelligent allocation unit, a path planning unit and a conflict avoidance unit. The intelligent allocation unit is used to intelligently allocate the handling tasks of the optical communication robot based on artificial intelligence technology and work tasks. The path planning unit is used to plan the travel route of the optical communication robot based on the handling task. The conflict avoidance unit is used to avoid conflicts in the travel routes of multiple optical communication robots based on artificial intelligence technology.

[0009] In one or more embodiments of the present invention, the collaborative sensing module is composed of a data acquisition and processing module and an information processing unit. The data acquisition and processing module is used to collect and process sensor data of the optical communication robot, and the information processing unit is used to process and transmit the collected sensor data.

[0010] In one or more embodiments of the present invention, the early warning and error correction module is composed of an early warning unit, an analysis and comparison unit, and an error correction control unit.

[0011] In one or more embodiments of the present invention, the error correction and warning module also includes a vehicle body, with a sensor module fixedly mounted on one side of the vehicle body. The sensor module can sense the positional relationship between the vehicle body and the environment during its travel, thereby enabling real-time adjustments to the vehicle's route. A protective housing is fixedly mounted on the outside of the vehicle body, and the protective housing and the vehicle body form a sensor control cavity. The sensor module is fixedly mounted within the sensor control cavity. A sensor protection plate is fixedly mounted on one side of the protective housing, and the sensor protection plate is positioned corresponding to the sensor module. The sensor protection plate provides safety protection for the sensor module. The diversion cleaning mechanism is fixedly mounted on the outside of the protective housing. The diversion cleaning mechanism is used to blow air to clean the sensor protection plate. The diversion cleaning mechanism consists of a blowing plate and a connecting air pipe. An exhaust hole is provided on the side of the blowing plate close to the sensor protection plate. The connecting air pipe is fixedly mounted above the blowing plate. A diversion dust filter component is fixedly mounted on the outside of the protective housing. The diversion dust filter component is used to divert gas and filter dust from the sensor control chamber. The reciprocating dust cleaning mechanism is fixedly mounted below the protective housing. The reciprocating dust cleaning mechanism is used to scrape and clean the sensor protection plate. The method of filtering the sensor protection plate with dust by the diversion cleaning mechanism avoids dust adhesion to the sensor protection plate, thereby avoiding the sensor module being affected by dust and causing detection errors. The reciprocating dust cleaning mechanism can assist in cleaning the sensor protection plate, thereby improving the accuracy of the sensor module's data detection of the vehicle body.

[0012] In one or more embodiments of the present invention, the air guide and dust filter assembly comprises a pair of air collecting cylinders, an exhaust fan, and a dust filter cylinder. The pair of air collecting cylinders are symmetrically mounted above the protective housing, the pair of exhaust fans are fixedly mounted within opposite sides of the pair of air collecting cylinders, and the pair of dust filter cylinders are fixedly mounted within opposite sides of the pair of air collecting cylinders. The air within the air collecting cylinders is guided and transported by controlling the operation of the exhaust fans, and the air guided within the air collecting cylinders is filtered for dust by the dust filter cylinders.

[0013] In one or more embodiments of the present invention, an exhaust pipe is fixedly connected to opposite ends of a pair of gas collecting cylinders, the exhaust pipe is connected to the sensor control chamber, an exhaust pipe is connected between the pair of gas collecting cylinders, the exhaust pipe is connected to the connecting air pipe, and an air blowing pipe is connected between the exhaust pipe and the sensor control chamber. The exhaust pipe, exhaust pipe, and air blowing pipe can connect the two ends of the gas collecting cylinder to the sensor control chamber respectively, thereby controlling the circulation of air in the sensor control chamber.

[0014] In one or more embodiments of the present invention, the reciprocating dust cleaning mechanism includes a scraper, a movable screw, and a guide light rod. The scraper contacts the outer surface of the sensor protection plate. The movable screw and the guide light rod are arranged below the scraper. The movable screw is threadedly connected to the scraper. The scraper is slidably connected to the guide light rod. One end of the movable screw is fixedly assembled with a driving component. The driving component consists of a pair of storage plates, a driving gear, a transmission gear, and a driving motor. The pair of storage plates are rotatably assembled on both sides of the movable screw, and the pair of storage plates are fixedly connected to the side of the protective housing. The driving gear is fixedly connected to the end of the movable screw located outside the storage plate. The transmission gear meshes with the driving gear, and the output shaft of the driving motor is fixedly connected to the transmission gear. The transmission gear can be driven to rotate by controlling the operation of the driving motor. The movable screw rotates synchronously under the meshing action of the driving gear and the transmission gear, so that the scraper can move with the rotation of the movable screw under the action of the internal and external threads. The movement of the scraper can scrape and clean the sensor protection plate.

[0015] Compared with the existing technology, the present invention provides an intelligent decision-making and planning module to intelligently allocate handling tasks, plan paths, and avoid travel routes for optical communication robots, thereby improving the intelligent operation of optical communication robots.

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0030] like Figure 1 As shown, an optical communication enhanced robot intelligent collaboration system in one embodiment of the present invention includes: an intelligent decision-making and planning module, a collaborative sensing module and an early warning and error correction module. The intelligent decision-making and planning module is used to intelligently plan the travel path of the optical communication robot, the collaborative sensing module is used to collect data and convert information from the sensors configured for the optical communication robot, and the early warning and error correction module is used to perform error correction and early warning processing on the collaborative sensing module.

[0031] like Figure 1 As shown, the intelligent decision-making and planning module consists of an intelligent allocation unit, a path planning unit and a conflict avoidance unit. The intelligent allocation unit is used to intelligently allocate the handling tasks of the optical communication robot according to artificial intelligence technology and the work tasks. The path planning unit is used to plan the travel route of the optical communication robot according to the handling tasks. The conflict avoidance unit is used to avoid conflicts in the travel routes of multiple optical communication robots based on artificial intelligence technology.

[0032] like Figure 1 As shown, the collaborative sensing module consists of a data acquisition and processing module and an information processing unit. The data acquisition and processing module is used to collect and process sensor data for the optical communication robot, and the information processing unit is used to process and transmit the collected sensor data.

[0033] like Figure 1 As shown, the early warning and error correction module consists of an early warning unit, an analysis and comparison unit, and an error correction control unit. The early warning unit is used to provide early warning prompts for the operating status of the optical communication robot, the analysis and comparison unit is used to analyze and compare sensor data, and the error correction control unit is used to perform error correction control on the optical communication robot.

[0034] like Figures 2 to 5 As shown, the error correction and warning module also includes a vehicle body 1, and a sensor module 2 is fixedly installed on one side of the vehicle body 1. The sensor module 2 can sense and detect the positional relationship between the vehicle body 1 and the environment during its movement, so that the movement route of the vehicle body 1 can be adjusted in real time, providing data support for the route planning of the vehicle body 1.

[0035] like Figure 5As shown, a protective housing 3 is fixedly mounted on the outside of the vehicle body 1. The protective housing 3 and the vehicle body 1 form a sensor control cavity, in which the sensor module 2 is fixedly mounted. The protective housing 3 provides assembly protection for the sensor module 2.

[0036] like Figure 8 As shown, a sensor protection plate 4 is fixedly mounted on one side of the protective housing 3 . The sensor protection plate 4 is arranged corresponding to the sensor module 2 . The sensor protection plate 4 provides safety protection for the sensor module 2 , thereby improving the detection accuracy of the sensor module 2 .

[0037] like Figures 5 to 7 As shown, the diversion cleaning mechanism 5 is fixedly assembled on the outside of the protective casing 3, and the diversion cleaning mechanism 5 is used for blowing dust off the sensor protection plate 4. The diversion cleaning mechanism 5 is composed of a blowing plate 501 and a connecting air pipe 502. An exhaust hole is provided on the side of the blowing plate 501 close to the sensor protection plate 4, and the connecting air pipe 502 is fixedly assembled above the blowing plate 501. Air is transported into the blowing plate 501 through the connecting air pipe 502, so that the sensor protection plate 4 can be blown and dust cleaned by discharging air through the blowing plate 501, thereby avoiding the situation where dust adheres to the outside of the sensor protection plate 4 and causes misjudgment of the sensor module 2.

[0038] like Figures 5 to 9 As shown, a guide dust filter component is fixedly mounted on the outside of the protective housing 3. The guide dust filter component is used to guide gas and filter dust from the sensor control chamber. The guide dust filter component consists of a pair of air collecting cylinders 7, an exhaust fan 701, and a dust filter cylinder 702. The pair of air collecting cylinders 7 are symmetrically mounted above the protective housing 3. The pair of exhaust fans 701 are fixedly mounted on opposite sides of the pair of air collecting cylinders 7, and the pair of dust filter cylinders 702 are fixedly mounted on opposite sides of the pair of air collecting cylinders 7. The air in the air collecting cylinders 7 is guided and transported by controlling the operation of the exhaust fans 701, and the air guided in the air collecting cylinders 7 is filtered by the dust filter cylinders 702.

[0039] like Figures 5 to 9As shown, an exhaust pipe 703 is fixedly connected to each of the opposite ends of the pair of air collecting cylinders 7. The exhaust pipe 703 is connected to the sensor control chamber. An exhaust pipe 704 is connected between the pair of air collecting cylinders 7. The exhaust pipe 704 is connected to the connecting air pipe 502. An air blowing pipe 705 is connected between the exhaust pipe 704 and the sensor control chamber. The exhaust pipe 703, the exhaust pipe 704, and the air blowing pipe 705 can connect the two ends of the air collecting cylinder 7 to the sensor control chamber respectively, so that the air in the sensor control chamber can be transported into the air collecting cylinder 7 along the exhaust pipe 703 under the action of the exhaust fan 701. After dust is filtered, it is transported into the sensor control chamber along the exhaust pipe 704 and the air blowing pipe 705. By accelerating the air circulation in the sensor control chamber, the sensor module 2 is guided and cooled. At the same time, the dust adhesion to the sensor module 2 can be avoided by blowing air again after dust filtering, thereby improving the detection accuracy of the sensor module 2.

[0040] like Figures 2 to 6 As shown, a reciprocating dust cleaning mechanism 6 is fixedly mounted below the protective housing 3 and is used to scrape and clean the sensor protection plate 4. The dust filtering process performed by the diversion cleaning mechanism 5 on the sensor protection plate 4 prevents dust from adhering to the sensor protection plate 4, thereby preventing the sensor module 2 from being affected by dust and causing detection errors. The reciprocating dust cleaning mechanism 6 provides auxiliary cleaning of the sensor protection plate 4, improving the accuracy of the sensor module 2's data detection of the vehicle body 1.

[0041] like Figures 2 to 6 As shown, the reciprocating dust cleaning mechanism 6 includes a scraper 601, a movable screw rod 602, and a guide light rod 603. The scraper 601 contacts the outer surface of the sensor protection plate 4, and the movable screw rod 602 and the guide light rod 603 are arranged below the scraper 601. The movable screw rod 602 is threadedly connected to the scraper 601, and the scraper 601 is slidingly connected to the guide light rod 603. One end of the movable screw rod 602 is fixedly equipped with a driving component, and the driving component consists of a pair of receiving plates 604, a driving gear 605, a transmission gear 606 and a driving motor 607. A pair of receiving plates 604 are rotatably assembled on both sides of the movable screw rod 602, and a pair of receiving plates 604 are fixedly connected to the side of the protective housing 3. The driving gear 605 is fixedly connected to one end of the movable screw rod 602 located outside the receiving plate 604, the transmission gear 606 is meshed with the driving gear 605, and the output shaft of the driving motor 607 is fixedly connected to the transmission gear 606. By controlling the operation of the drive motor 607, the transmission gear 606 can be driven to rotate, and the movable screw 602 rotates synchronously under the meshing action of the drive gear 605 and the transmission gear 606, so that the scraper 601 can move with the rotation of the movable screw 602 under the action of the internal and external threads, and the sensor protection plate 4 can be scraped and cleaned by the movement of the scraper 601.

[0042] During specific use, when the vehicle body 1 is moving and transporting goods, the sensor module 2 can perform position detection and data detection on the vehicle body 1, so that the intelligent decision-making and planning module can plan the route and avoid conflicts for the vehicle body 1.

[0043] At the same time, in actual application, the air in the sensor control chamber can be extracted by controlling the operation of a pair of exhaust fans 701. Under the action of the exhaust fan 701, the air in the sensor control chamber is transported to the air collecting cylinder 7 along the exhaust pipe 703, and after being filtered by the dust filter cylinder 702, it is discharged into the sensor control chamber along the exhaust pipe 704 and the blowing pipe 705. By extracting, filtering and discharging the air in the sensor control chamber, the air circulation in the sensor control chamber can be accelerated, thereby dissipating heat and filtering dust for the sensor module 2.

[0044] In addition, the air after dust filtering can be transported to the blowing plate 501 along the exhaust pipe 704 and the connecting air pipe 502, and discharged from the blowing plate 501. The air can be discharged to the sensor protection plate 4 through the blowing plate 501, so that the sensor protection plate 4 can be blown and dust-cleaned, thereby avoiding the adverse effects of dust adhering to the surface of the sensor protection plate 4 on the detection accuracy of the sensor module 2.

[0045] In addition, the transmission gear 606 can be driven to rotate by controlling the operation of the drive motor 607, and the movable screw rod 602 can drive the scraper 601 to move along the guide light rod 603 under the meshing action of the drive gear 605 and the transmission gear 606. By controlling the forward and reverse rotation of the output shaft of the drive motor 607, the scraper 601 can move back and forth on the surface of the sensor protection plate 4. The reciprocating movement of the scraper 601 can scrape and clean the dust on the surface of the sensor protection plate 4, thereby further improving the detection accuracy of the sensor module 2.
