Abstract
Description
Technical Field
[0001] The invention belongs to the field of control technology, and in particular relates to an automatic explosion-proof door control system based on an AGV trolley. Background Art
[0002] The collaborative operation of automated production and logistics transportation is increasingly becoming the key to improving efficiency and competitiveness in many industries. Among them, AGV (Automated Guided Vehicle) is a highly intelligent automatic guided transportation equipment, which is widely used in various industrial environments, especially in areas with extremely high requirements for logistics accuracy and automation, such as the key material transportation tasks between production workshops and warehouses in industries such as petrochemicals.
[0003] In these industrial sites, in addition to the pursuit of efficient automated production and logistics operations, safe production is of paramount importance. Since chemical production involves a large number of flammable and explosive chemicals, the risk of explosion is always present. Once an explosion occurs, if there is a lack of effective isolation and protection measures, the disaster will spread rapidly, causing immeasurable casualties, equipment damage, and environmental pollution. Explosion-proof doors have become an important facility to ensure regional safety.
[0004] Although traditional explosion-proof doors can resist explosion shocks to a certain extent, they have obvious deficiencies in working in coordination with AGV trolleys. Previous explosion-proof doors mostly adopted manual or simple timing control methods, which lack flexibility and cannot be adjusted according to real-time changes in actual production scenarios. For example, when temporary changes or failures in the production process cause delays in the operation of the AGV trolley, the timed opening of the explosion-proof door may cause unnecessary safety hazards or affect the efficiency of material transportation. It is difficult to achieve intelligent linkage between the door and the trolley operation, which not only easily leads to obstruction of the transportation path of the AGV trolley and reduces logistics efficiency, but also may expand the explosion hazard due to door control errors in emergency situations. Manual operation relies on human judgment and intervention, which is not only labor-intensive, but also prone to accidents due to human negligence or untimely response. Summary of the invention

DETAILED DESCRIPTION
[0022] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0023] See also Figure 1The embodiment of the present invention provides an automatic explosion-proof door control system based on an AGV, which includes: an explosion-proof door device, a distance measuring device and a control device.
[0024] The explosion-proof door device has the function of resisting the impact of explosions, and has the function of controlling the door leaf to open or close under the control of a control signal. The distance measuring device is arranged on the explosion-proof door device, and is used to measure the door-car distance between the explosion-proof door device and the AGV trolley and the driving speed of the AGV getting off the trolley. When the AGV trolley drives towards the explosion-proof door device, the door-car distance and the driving speed can be obtained through the distance measuring device. The control device has a first working mode. In the first working mode, the door-car distance, the driving speed and the door leaf opening of the explosion-proof door device (i.e. the opening of the door leaf of the explosion-proof door device) can be obtained, and then the opening speed and opening time of the explosion-proof door device are determined according to the door-car distance, the driving speed and the opening, and a control signal is generated accordingly, and then sent to the explosion-proof door device. After receiving the control signal, the explosion-proof door device acts under the control of the control signal. For example: when it is detected that the AGV car is driving towards the explosion-proof door device at a certain speed, the control device will plan the opening time and speed of the door leaf in advance according to the real-time driving speed of the car, the door-car distance information and the door leaf opening of the explosion-proof door device to ensure that the AGV car can pass smoothly and efficiently. Close the door leaf quickly and safely after the car passes. The door leaf opening α generally refers to: the door leaf opening suitable for the AGV car to pass through, which does not necessarily mean that the door leaf is fully open, which can be determined in advance. In practical applications, the speed is controlled at a uniform speed or travels at a uniform speed, which can be controlled by the following formula.
[0025] In the formula, r is the rotation radius of the door leaf, v1 is the opening speed of the door leaf, v2 is the driving speed of the AGV, s is the door-car distance, and v1 must be equal to or greater than απrv 2 / 180s. Accordingly, the start time of controlling the door leaf is απr / 180v1, based on which the opening timing of the door leaf can be controlled.
[0026] The distance measuring device includes: a reader, a tag and a distance measuring unit. The reader (or reader-writer) and the tag (or transponder) are devices based on radio frequency identification technology, that is, the two are connected by communication through radio frequency identification technology. The reader is set on the explosion-proof door device, such as on the door frame, and has a certain identification range. The tag is set on the AGV trolley. When the AGV trolley enters the identification area (or working area) of the reader, it will be recognized by the reader. At this time, the reader can know that an AGV trolley has entered its identification area. Further, the tag will store the identity information of the AGV trolley. The reader transmits a radio frequency signal through the antenna. After the tag receives the signal, it uses its own energy (in this case, the tag is a passive tag) or internal power supply (in this case, the tag corresponds to an active tag) to send the stored information back to the reader. Then the reader can know the identity information of the AGV trolley, that is, it knows which AGV trolley is entering its identification area.
[0027] The distance measuring unit is arranged on the explosion-proof door device, such as on the top of the door frame, and its distance measuring area is within the identification area of the reader. By the following arrangement, the search area of the distance measuring unit for the AGV can be narrowed, that is, the AGV car is searched within the identification area of the reader. It can also be used as a priori information or auxiliary verification information when the distance measuring unit measures the distance, that is, the rationality of the distance measuring result of the distance measuring unit can be verified. If the distance measuring result obtained by the distance measuring unit is not within the identification area of the reader, a prompt message is generated, which is used to indicate the existence of a measurement error or fault. After receiving the prompt message, the staff can go to the site for disposal. The distance measuring unit scans in a rotating manner. After scanning and identifying the AGV car, it stops scanning, that is, stops rotating, and then measures the distance to obtain the door car distance measurement information. The distance measuring unit is also used to obtain the driving speed. Furthermore, the driving direction of the AGV car can also be determined. Through the distance measuring unit arranged on the outside of the explosion-proof door device, it can be determined that the AGV car is driving from the outside to the inside of the door; through the distance measuring unit arranged on the inside of the explosion-proof door device, it can be determined that the AGV car is driving from the inside to the outside of the door. A reflector can be installed on the AGV car. By installing the reflector, the laser emitted by the distance measuring unit and reflected by the reflector can be distinguished from the laser reflected by other objects or objects in the environment. The distinction can be achieved by judging the intensity of the reflected laser. Since the reflector is installed on the AGV car, the distance measuring unit can determine that the reflected laser comes from the AGV car through judgment.
[0028] The distance measuring unit may include a laser distance measuring sensor, and in other embodiments, it may also be an infrared radar, which is not specifically limited in this embodiment. When the distance measuring unit includes a laser distance measuring sensor, it may include: 3 laser distance measuring sensors. At this time, the door-car distance can first use the 3 laser distance measuring sensors to obtain the positioning information of the trolley using the triangulation positioning method, and then calculate it with the positioning information of the door to obtain the door-car distance. It may also include: 1 laser distance measuring sensor. At this time, the door-car distance is directly obtained by 1 laser distance measuring sensor. The measurement accuracy of the laser distance measuring sensor can reach the millimeter level, which can provide a reliable basis for the precise control of the explosion-proof door device. The distance measurement principle of the laser distance measuring sensor is to calculate the distance by emitting a laser beam and then measuring the time it takes for the laser to be reflected from the emission to the target object.
[0029] In the AGV position sensing link, a distance measurement unit is combined with ultra-high frequency radio frequency identification (RFID) technology. At the same time, the deployed reader cooperates with the tag on the AGV to accurately identify the identity of the AGV and confirm the positioning in the preset area, ensuring that the system can accurately track the location information of each AGV in a complex industrial environment. In other words: the high-precision advantage of distance measurement and the identity recognition and regional positioning functions of RFID technology are fully utilized to achieve all-round and high-precision acquisition of AGV position information, effectively solving the problem of inaccurate and incomplete traditional position sensing methods.
[0030] In terms of the control device of the control system, a high-performance embedded microprocessor is used. The processor has powerful data processing capabilities, can quickly receive and analyze information from the position sensing module, can integrate multi-variable information to make fast and accurate decisions, and dynamically adjust the control strategy of the explosion-proof door according to different working conditions. This is the core of realizing the intelligent collaboration between the explosion-proof door and the AGV car, overcoming the defect that the simple control logic of the existing system cannot cope with complex scenarios.
[0031] The explosion-proof door device includes: a door frame, a door leaf 300, a bolt 301, an automatic bolt driving mechanism 302, an upper hinge 303, a lower hinge 304 and an automatic bolt driving mechanism 305. The door leaf 300 serves as a protective body, and is used to block explosion shock waves, explosion fragments and flames, etc., to prevent the accommodation space from being affected. When in use, the door leaf 300 is rotatably mounted on the door frame. The bolt 301 is mounted on the door leaf 300 and is used to lock the closed door leaf 300. When the door leaf 300 is closed, the bolt moves, such as entering a lock box provided on the door frame, thereby locking the closed door leaf 300; before the door leaf 300 is opened, the bolt moves, such as retracting from the lock box, thereby unlocking the closed door leaf 300. The automatic bolt driving mechanism 302 is connected to the bolt, and is used to automatically drive the bolt 301 to move, thereby locking or unlocking the door leaf 300. In Figure 1 When locking the door leaf 300, the door latch 301 moves to the left; when unlocking the door leaf 300, the door latch 301 moves to the right. The upper hinge 303 and the lower hinge 304 are used to make the door leaf 300 rotate to open and close, one end of which is connected to the door leaf 300 and the other end is set on the door frame. The door leaf automatic drive mechanism 302 is used to output the power for rotating the door leaf 300. It is connected to the upper hinge 303 and is used to drive the upper hinge 303 to rotate, thereby driving the door leaf 300 connected to the upper hinge 303 to rotate, thereby realizing the opening or closing of the door leaf 300.
[0032] The door leaf automatic drive mechanism 305 is an electric drive mechanism, which includes: a servo motor 15 and a clutch 21. The servo motor 15 is used to output power for rotating the door leaf 300. The clutch is used to connect the servo motor 15 and the upper hinge 303 to transmit power. The clutch can be a pneumatic clutch, preferably a pneumatic gear clutch. Specifically, the output shaft of the servo motor 15 is connected to one end of the universal coupling 9 by a key, the other end of the universal coupling is connected to the input end of the clutch by a key, and the output end of the clutch is connected to the rotating shaft of the upper hinge by a key. The input end (i.e., the input shaft) of the clutch is installed in the door frame area through a bearing seat mounting plate 18 provided with a bearing seat 17. Such an arrangement can ensure that the door leaf rotates reliably and stably under automatic control. Specifically, the servo motor 15 is connected to the universal coupling 9 through a reducer 14. The reducer 14 is installed on the reducer mounting seat mounting plate 16 through the reducer mounting seat 13, and the reducer mounting seat mounting plate 16 is installed in the door frame area. The motor side connecting shaft (i.e., the output end of the reducer) 12 is connected to one end of the universal coupling 9 through a key 11 and is also connected through a screw 10. The other end of the universal coupling 9 is connected to the clutch side shaft (i.e., the input end of the clutch) 19 through a key 8. The rotating shaft of the upper hinge 303 is connected to the output end of the clutch 21 through a key 20 and a connecting plate 1. The connecting plate 1 is connected to the output end of the clutch through a bolt 2. A key 5 is provided inside the clutch 21 to improve the reliability of the rotation connection. A retaining ring 7 is provided at the bearing 6.
[0033] The automatic door bolt driving mechanism is a hydraulic driving mechanism, which is used to make the door bolt perform an extending movement or a retracting movement.
[0034] For the driving actuator of the explosion-proof door device, an advanced electric hydraulic driving system is adopted, which is a combination of the door leaf driving mechanism of the electric driving mechanism and the door bolt driving mechanism of the hydraulic driving mechanism. The system is composed of a servo motor, a hydraulic pump, a hydraulic cylinder and a hydraulic control valve group. The servo motor preferably adopts a high-torque servo motor, the hydraulic pump preferably adopts a precision hydraulic pump, and the hydraulic cylinder preferably adopts a high-strength hydraulic cylinder. The servo motor controls the opening and closing speed of the door leaf according to the instructions of the control device. The hydraulic pump controls the output flow and pressure through the servo valve (or hydraulic control valve group), and then controls the opening and closing of the door bolt, so as to achieve the smooth and rapid opening and closing of the door leaf of the explosion-proof door device. The explosion-proof door device is also provided with a locking identification module for identifying and feeding back to the control device to control the locking of the hydraulic cylinder. The hydraulic control valve group is used to accurately adjust the flow direction and pressure of the hydraulic oil under different working conditions. For example, when an explosion impact occurs, it can quickly switch to a pressure-maintaining locking state to ensure that the explosion-proof door device is tightly closed and effectively resist the strong impact force generated by the explosion. At the same time, in order to improve the reliability and stability of the system, the driving actuator is also equipped with a redundant backup power supply and a fault self-diagnosis module. The redundant backup power supply can automatically switch the power supply when the main power supply fails, ensuring that the explosion-proof door device can still operate normally in an emergency. The fault self-diagnosis module is used to monitor the working status of each component of the drive actuator in real time. When an abnormality is detected, an alarm message is immediately sent to the control device and corresponding protective measures are taken, such as emergency braking, safety locking, etc.
[0035] The driving actuator of the explosion-proof door device is a combination of a servo motor, a hydraulic pump, a hydraulic cylinder and a control valve group. As a power source, the servo motor can accurately control the speed and torque output, and can accurately control the movement stroke and speed of the door leaf according to the needs. Driven by the servo motor of the hydraulic station, the hydraulic pump converts mechanical energy into hydraulic energy, outputs through pressure and flow, and provides the necessary hydraulic power source for the operation of the subsequent hydraulic system. The hydraulic cylinder is an actuator that uses hydraulic energy to achieve linear reciprocating motion. It converts the hydraulic energy provided by the hydraulic pump into mechanical energy, thereby pushing the door bolt (or door bolt) of the explosion-proof door device to open and close. The hydraulic control valve group is used to accurately control the flow direction, pressure, flow, etc. of the hydraulic oil in the hydraulic system. According to the different working conditions and requirements of the system, the flow of hydraulic oil between various components can be flexibly allocated to achieve the stability, accuracy and efficiency of the movement of the door leaf of the explosion-proof door device. Through the ingenious combination design of the servo motor, hydraulic pump, hydraulic cylinder and hydraulic control valve group, the electric hydraulic drive actuator can not only achieve accurate motion control of the explosion-proof door, but also ensure its smooth and efficient movement during normal operation.
[0036] The explosion-proof door device also includes: a hand wheel driving mechanism, which is used to manually drive the door bolt to move to lock or unlock the door leaf, so that the door bolt can be extended or retracted in a manual state.
[0037] In addition, in terms of communication network, this system has built a redundant communication architecture based on the combination of industrial Ethernet and wireless communication technology. Industrial Ethernet is used for high-speed and stable data transmission between the automatic explosion-proof door control system and the factory central control system to achieve centralized information management and remote monitoring. The wireless communication module ensures that the AGV car and the automatic explosion-proof door control system can exchange location information in real time and reliably. The use of wireless frequency bands and encrypted communication protocols effectively avoids electromagnetic interference and information leakage risks in industrial environments, further improving the safety and stability of the entire system.
[0038] This system can control the opening and closing speed of the door leaf at a uniform speed. When the AGV trolley reaches the preset position, the door valve sensing module interacts with the main control system to control the opening and closing of the door. After the door is closed, the locking recognition module determines whether it is in place. The control system exchanges information with the test equipment in the explosion-proof room. Before the equipment is operated, the locking recognition module feedback controls the door locking. During operation, the door is not allowed to be opened unless the emergency stop button is pressed to cut off the power. The explosion-proof door device is opened and closed by the sensing AGV trolley (corresponding to the first working mode) and manually (corresponding to the second working mode). It can also include: main control system control (corresponding to the third working mode). At this time, the main control system has a higher priority than the sensing AGV trolley in the automatic state, and it cannot be operated manually. The switch realizes remote control and on-site dual control. An explosion-proof operation box, emergency stop button, operation and fault indicator lights are set on site.
[0039] The automatic explosion-proof door control system based on the AGV provided by the embodiment of the present invention has the following advantages:
[0040] The explosion-proof door device and the AGV trolley have achieved highly intelligent coordination. Through precise position sensing and efficient control systems, the explosion-proof door device can realize accurate and timely opening and closing actions based on the real-time position and operating status of the AGV trolley while ensuring safety, greatly improving the efficiency of industrial logistics and transportation, reducing logistics stagnation time caused by unreasonable door control, and making the material transportation process smoother.
[0041] Significantly enhanced safety and reliability. When facing explosion risks, the system can not only effectively resist explosion impact with advanced drive actuators, but also benefit from redundant design and fault self-diagnosis functions to ensure that the explosion-proof door device can always work normally in various complex and harsh industrial environments and sudden fault conditions, providing a reliable safety protection barrier for personnel, equipment and production environment, and effectively reducing the degree of harm and spread of explosion accidents.
[0042] It has good adaptability and scalability. The communication architecture based on the combination of industrial Ethernet and wireless communication technology enables it to be easily integrated into the existing industrial automation control system, convenient for integration with other production equipment and management systems, and can flexibly adjust system parameters and functional modules according to different industrial scenarios and production needs to adapt to a variety of application scenarios.
[0043] This solution involves the field of industrial automation and security protection technology, especially focusing on the technical scope of door control systems in specific industrial environments where there is a risk of explosion and AGVs are running. The automatic explosion-proof door control system based on AGV position sensing came into being, aiming to accurately coordinate the running path of the AGV with the opening and closing of the explosion-proof door, which not only ensures the safety of personnel, equipment and materials in the industrial production process, avoids the spread and diffusion of disasters when explosions occur, but also ensures the smoothness of automated logistics transportation routes, and achieves the goal of efficient, safe and intelligent integration of industrial production and logistics management, effectively filling the technical gap in the cross-field of industrial automation and security protection regarding the collaborative operation control system of AGVs and explosion-proof doors.
[0044] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
