Abstract

The present invention discloses a dual-track all-electric intelligent conveying and closed-loop monitoring and dispatching system, which relates to the technical field of dispatching systems, and includes a cache workshop and a car-changing assembly. The interior of the cache workshop is penetrated by a dual-track track, and the car-changing assembly is arranged inside the cache workshop. The present invention uses the self-checking speed of the working smart rail vehicle to replace the slow-moving smart rail vehicle by lifting and lowering the second double-layer track and the first double-layer track, while replacing the smart rail vehicle without affecting the subsequent movement of the normal-speed smart rail vehicle. When replacing the smart rail vehicle, the product can be transferred to the surface of the spare smart rail vehicle by using the transmission of the transmission belt, and the tooth groove on the surface of the transmission belt is used to fit with the product carrier plate during the transition to prevent the end of the product carrier plate from falling at the empty space between the transmission belts. At the same time, the product carrier plate is reinforced as it moves with the smart rail vehicle to prevent the product carrier plate from shaking and displacing during movement.

Description

Technical Field

[0001] The present invention relates to the technical field of dispatching systems, and in particular to a dual-track all-electric intelligent conveying and closed-loop monitoring dispatching system. Background Art

[0002] In the existing product production process, intelligent conveying equipment is an indispensable and important equipment today. It can realize the assembly line-like movement of products, allowing products to automatically complete assembly, testing and other processes, thereby greatly improving product production efficiency.

[0003] However, traditional conveying equipment, such as the common rail shuttles on the market, are inevitably prone to aging when they are used to carry products along the track. Since the rail shuttles are all individually set up, the aged rail shuttles will slow down when moving on the track, causing subsequent rail shuttles moving at normal speed to become blocked, thereby reducing production and assembly efficiency.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a dual-track all-electric intelligent transportation and closed-loop monitoring and scheduling system is proposed. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention provides a dual-track all-electric intelligent transportation and closed-loop monitoring and scheduling system, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a double-track all-electric intelligent transportation and closed-loop monitoring and scheduling system, including a cache workshop and a car changing assembly, the interior of the cache workshop is penetrated by a double-track track, the car changing assembly is arranged inside the cache workshop, the car changing assembly includes an electric lifting rod, a first double-layer track, a first upper track, a second upper track, a servo motor, a gear transmission box, a screw rod and a second double-layer track, the top of the electric lifting rod is connected to the first double-layer track, the first upper track and the second upper track are fixed on the upper part of the inner wall of the cache workshop, and a gear transmission box is fixed above the end of the first upper track on the inner wall of the cache workshop, the top of the gear transmission box is connected to the servo motor, and the bottom of the gear transmission box is connected with a screw rod around, the outer wall of the screw rod is connected to the second double-layer track through a movable sleeve, a working smart rail car is slidably provided inside the double-track track, and a spare smart rail car is slidably provided inside the first upper track.

[0007] Furthermore, the upper track of the first double-layer track is flush with the double-track track, and the first upper track is located directly above the double-track track.

[0008] Furthermore, the first upper rail has a T-shaped structure, and the first upper rail and the second upper rail are located at the same height.

[0009] Furthermore, the upper track of the second double-layer track is flush with the first upper track, and the lower track of the second double-layer track is flush with the double-track track.

[0010] Furthermore, a product transfer assembly is provided on the top surface of the working smart rail vehicle and the spare smart rail vehicle. The product transfer assembly includes a bracket, a drive motor and a transmission belt. A drive motor is provided on one side of the bracket, and the outer wall of the output shaft of the drive motor is connected to the transmission belt.

[0011] Furthermore, the product transfer assembly also includes teeth and grooves, and the surface of the transmission belt is provided with teeth and grooves.

[0012] Furthermore, the product transfer assembly further includes a product carrying plate, and the product carrying plate is fitted inside the tooth groove.

[0013] Furthermore, the double-track track passes through operator B, operator A and operator C in sequence after passing through the cache workshop, and a cross-corner machine is provided at the double-track track between operator A and operator C.

[0014] Furthermore, the double-track track between the cross-corner machine and the cache workshop passes through the assembly test unit and the first elevator in sequence, and a second elevator is provided at the end of the double-track track located at the C operator, and the double-track track between the first elevator and the second elevator is in two parallel layers arranged up and down.

[0015] Furthermore, the implementation method of the dual-track all-electric intelligent transportation and closed-loop monitoring and scheduling system is as follows:

[0016] Operator A continuously loads the working smart track car, which moves towards the cross-corner machine;

[0017] The working smart track vehicle moves to the cross-corner machine, which turns the working smart track vehicle 90 degrees and then moves to the assembly and testing machine;

[0018] After the working intelligent rail vehicle has been assembled and tested, it will be moved towards the first elevator.

[0019] The working smart rail vehicle marked as OK continues to move along the upper level toward the cache workshop after passing the first elevator;

[0020] The work smart track vehicle marked as NG is lowered from the work smart track vehicle to the lower track and moves to the cross-corner machine. It passes through the lower level of the cross-corner machine and moves to the second elevator. The second elevator returns to the upper level. After operator C performs another maintenance and inspection on the product, the work smart track vehicle originally marked as NG passes through the upper level of the cross-corner machine again and moves to the assembly test machine, thus entering the assembly test;

[0021] The working smart rail vehicle marked as OK enters the cache workshop after passing the corner. If a working smart rail vehicle is aged, the products on the surface of the aged working smart rail vehicle will be transferred to the spare smart rail vehicle in the cache workshop. The spare smart rail vehicle will return to the double-track track for movement, and the aged working smart rail vehicle will move along the second upper track to the preset position after removing the products and wait for maintenance personnel to inspect it.

[0022] The unaged working smart rail vehicle and the spare smart rail vehicle after transferring the product move along the double track toward operator B, who then takes the completed product off the smart rail vehicle.

[0023] The empty car continues to move to the right, passes the corner structure and moves towards operator A, who loads the material again, thus completing a production cycle.

[0024] The present invention provides a dual-track all-electric intelligent conveying and closed-loop monitoring and dispatching system, which has the following beneficial effects:

[0025] 1. The dual-track all-electric intelligent conveying and closed-loop monitoring and dispatching system can replace the slow-moving smart rail car by self-checking the speed of the working smart rail car and raising and lowering the second double-layer track and the first double-layer track. The replacement of the smart rail car does not affect the subsequent movement of the normal-speed smart rail car. When replacing the smart rail car, the product can be transferred to the surface of the spare smart rail car by using the transmission belt. During the transition, the tooth groove on the surface of the transmission belt and the structure of the product carrier plate are used to prevent the end of the product carrier plate from falling in the gap between the transmission belts. At the same time, the product carrier plate is reinforced as the smart rail car moves to prevent the product carrier plate from shaking and displacement during movement.

[0026] 2. This dual-track, all-electric intelligent conveying and closed-loop monitoring and scheduling system transforms conveying components from traditional, fixed machines into intelligent, interchangeable vehicles. This system provides real-time tracking of current location, material status, production steps, finished product yield, and production efficiency. The equipment tracks include flexible connections and power supply interfaces, and, using developed models, enable rapid design, simulation, and construction of the desired conveyor track. The modular design makes the track simple and easy to use, minimizing the time and cost required for on-site construction, subsequent maintenance, and production line changes.

[0027] 3. This dual-track all-electric intelligent conveying and closed-loop monitoring and scheduling system is different from the common logistics four-way shuttle vehicles on the market with a length and width of 1000*1000mm. The present invention has a newly designed miniature intelligent rail vehicle and track system. The external dimensions of the intelligent rail vehicle can be as small as 120*120mm, thus enabling intelligent conveying and scheduling in the field of automated assembly.

[0041] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0042] like Figure 1-Figure 5As shown, the present invention provides a technical solution: a double-track all-electric intelligent conveying and closed-loop monitoring and dispatching system, including a cache workshop 1 and a car-changing component 3, the interior of the cache workshop 1 is penetrated by a double-track track 2, the car-changing component 3 is arranged inside the cache workshop 1, and the car-changing component 3 includes an electric lifting rod 301, a first double-layer track 302, a first upper track 303, a second upper track 304, a servo motor 305, a gear transmission box 306, a screw rod 307 and a second double-layer track 308, the electric lifting rod 301 The top of the cache workshop 1 is connected to the first double-layer track 302, the upper part of the inner wall of the cache workshop 1 is fixed with the first upper track 303 and the second upper track 304, and the end of the first upper track 303 is fixed to the inner wall of the cache workshop 1. A gear transmission box 306 is fixed above the end of the first upper track 303. The top of the gear transmission box 306 is connected to a servo motor 305, and the bottom of the gear transmission box 306 is connected to a screw rod 307 around the periphery. The outer wall of the screw rod 307 is connected to the second double-layer track 308 through a movable sleeve. The double-track track 2 is internally provided with a working intelligent sliding mechanism. The rail car 4 is provided with a spare smart rail car 5 for sliding inside the first upper track 303. The upper track of the first double-layer track 302 is flush with the double-track track 2, and the first upper track 303 is located directly above the double-track track 2. The first upper track 303 is a T-shaped structure, and the first upper track 303 and the second upper track 304 are at the same height. The upper track of the second double-layer track 308 is flush with the first upper track 303, and the lower track of the second double-layer track 308 is flush with the double-track track 2. A product transfer assembly 6 is provided on the top surface of both the smart track vehicle 4 and the spare smart track vehicle 5. The product transfer assembly 6 includes a bracket 601, a drive motor 602, and a transmission belt 603. The drive motor 602 is provided on one side of the bracket 601, and the transmission belt 603 is connected to the outer wall of the output shaft of the drive motor 602. The product transfer assembly 6 also includes a tooth groove 604. The surface of the transmission belt 603 is provided with a tooth groove 604. The product transfer assembly 6 also includes a product carrying plate 605. The product carrying plate 605 fits inside the tooth groove 604.

[0043] The specific operation is as follows: both the working smart rail car 4 and the spare smart rail car 5 are equipped with speed sensors. When a working smart rail car 4 slows down while moving along the double-track track 2, it indicates that it may have an aging problem. At this time, the possibly aging working smart rail car 4 moves along the normal process until it enters the cache workshop 1 and reaches the upper track of the first double-layer track 302. At this time, the electric lifting rod 301 extends to lift the first double-layer track 302 until the lower track of the first double-layer track 302 is flush with the double-track track 2, so that the subsequent working smart rail car 4 with normal speed can pass normally, and the upper track of the first double-layer track 302 is flush with the first upper track 303 and the second upper track 304;

[0044] At this time, the spare smart track vehicle 5 in the first upper track 303 is flush with the working smart track vehicle 4 that may be aging and is arranged side by side. At this time, the driving motors 602 on the surfaces of the two side-by-side smart track vehicles drive the transmission belt 603 to transmit, so that the product carrier plate 605 carrying the assembled and tested products on its surface is transferred to the transmission belt 603 on the surface of the spare smart track vehicle 5. After the transfer, the bottom of the product carrier plate 605 fits with the tooth groove 604 of the transmission belt 603 on the surface of the spare smart track vehicle 5, thereby stabilizing the transferred product carrier plate 605.

[0045] The spare smart track vehicle 5 carries the product carrier plate 605 and moves along the first upper track 303 to the upper track of the second double-layer track 308, while the working smart track vehicle 4 after removing the product moves in the opposite direction to move along the second upper track 304 to a preset position to wait for maintenance personnel to inspect it.

[0046] The output shaft of the servo motor 305 drives the screw rods 307 to rotate synchronously in the same direction through the gear transmission box 306, so that the movable sleeve carries the second double-layer track 308 downward, so that the upper track of the second double-layer track 308 is flush with the double-track track 2. At this time, the spare smart track vehicle 5 can move along the double-track track 2 and enter the next process;

[0047] Finally, the second double-layer track 308 and the first double-layer track 302 are reset and the products of the possibly aged smart rail vehicles are transferred next time;

[0048] Based on the above description, the present invention replaces the slow-moving smart rail car by self-checking the speed of the working smart rail car 4 and raising and lowering the second double-layer track 308 and the first double-layer track 302. When replacing the smart rail car, it does not affect the movement of the subsequent normal-speed smart rail car. When replacing the smart rail car, the product can be transferred to the surface of the spare smart rail car 5 by using the transmission belt 603. During the transition, the tooth groove 604 on the surface of the transmission belt 603 is used to fit with the product carrier plate 605 to prevent the end of the product carrier plate 605 from falling at the empty space between the transmission belts 603. At the same time, the product carrier plate 605 is reinforced as the smart rail car moves to prevent the product carrier plate 605 from shaking and displacing during movement.

[0049] like Figures 1-6As shown, after passing through the buffer workshop 1, the double-track track 2 passes through operator B 7, operator A 8 and operator C 9 in sequence, and a cross-corner machine 10 is provided at the double-track track 2 between operator A 8 and operator C 9. The double-track track 2 between the cross-corner machine 10 and the buffer workshop 1 passes through the assembly test unit 11 and the first elevator 12 in sequence, and a second elevator 13 is provided at the end of the double-track track 2 located at operator C 9. The double-track track 2 between the first elevator 12 and the second elevator 13 is arranged in two parallel layers. The implementation method of the double-track all-electric intelligent conveying and closed-loop monitoring and scheduling system is as follows:

[0050] Operator A 8 continuously loads the working smart track car 4, and the working smart track car 4 moves toward the cross-corner machine 10;

[0051] The working smart track vehicle 4 moves to the cross-angle machine 10, which turns the working smart track vehicle 4 ninety degrees and then moves to the assembly and testing unit 11;

[0052] After the working intelligent rail vehicle 4 is assembled and tested by the assembly and testing unit 11, it moves out toward the first hoist 12;

[0053] The working smart rail vehicle 4 marked as OK continues to move along the upper level toward the cache workshop 1 after passing the first elevator 12;

[0054] The working smart track vehicle 4 marked as NG is lowered from the working smart track vehicle 4 to the lower track and moves to the cross-corner machine 10. After passing the lower level of the cross-corner machine 10, it moves to the second elevator 13. The second elevator 13 returns to the upper level. After the C operator 9 performs another maintenance and inspection on the product, the working smart track vehicle 4 originally marked as NG passes the upper level of the cross-corner machine 10 again and moves to the assembly test unit 11, thereby entering the assembly test;

[0055] The working smart track vehicle 4 marked as OK enters the buffer workshop 1 after passing the corner. If a working smart track vehicle 4 is aged, the products on the surface of the aged working smart track vehicle 4 are transferred to the spare smart track vehicle 5 in the buffer workshop 1. The spare smart track vehicle 5 returns to the double-track track 2 for movement. After removing the products, the aged working smart track vehicle 4 moves along the second upper track 304 to a preset position to wait for maintenance personnel to inspect it.

[0056] The unaged working smart rail vehicle 4 and the spare smart rail vehicle 5 after transferring the products move along the double-track track 2 toward operator B 7, who then takes the finished products off the smart rail vehicle.

[0057] The empty vehicle continues to move to the right, passes the corner structure and moves towards operator A 8, who then loads the material again, thus completing a production cycle.

[0058] The specific system configuration of the present invention is as follows:

[0059] System configuration and initialization are completed by the main control system, which consists of an industrial computer and a main control board. The industrial computer and the main control board communicate via Ethernet.

[0060] First, power on the system and turn on the power switches of all smart rail vehicles and modules.

[0061] Double-click the debugging system program on the industrial computer system desktop to display the login window;

[0062] Enter your username and password to log in to the software. Figure 6 As shown;

[0063] The software mainly includes real-time status, project management, device management, information management, user management, monitoring interface, and software settings. Under the device management interface, the component library is displayed in a classified directory tree structure. Click the system scan button to scan all unbound components in the current wireless network and automatically classify them into the corresponding directory tree and display them as icons. (If there are two systems in an area, the bound components will not be scanned by the other system.) The component serial number and hardware address can be set through the edit button. The middle main window is the configuration interface. Drag the components scanned from the component library on the left into the middle configuration window and set the device operation order and branches through connection.

[0064] Operator Station (Station01):

[0065] The smart track vehicle (hereinafter referred to as the vehicle) enters the operator's station, detects the deceleration block, slows down, and detects the stop block, stops. At this time, the code reader in the vehicle is triggered to recognize the position code through the QR code, for example, Station01. The wireless interaction module built into the vehicle is set to only receive interaction requests from the wireless interaction module outside Station01.

[0066] After the operator completes the operation, he presses the start button, and the external wireless network module fixed on the operator's station track sends the station start instruction to the built-in wireless interaction module of the trolley;

[0067] The process flag inside the trolley is automatically set to Station01-OK, and the trolley enters Station02, and starts running;

[0068] Cross steering machine (Station02):

[0069] The trolley moves downwards and reaches the front of the cross-corner machine. After passing the deceleration and stop block, the trolley stops in front of the steering machine entrance.

[0070] At this time, the code reader inside the car is triggered to recognize the position code through the QR code and send a car arrival signal to the corner machine; for example, "Station02 upper entrance A request to enter";

[0071] After the steering machine completes the previous action and receives "Station02 upper entrance A", the upper turntable rotates to the A entrance position and sends a permission to the car to enter;

[0072] The car receives the permission command from the upper port A of Station02 and starts running into the upper layer of the steering gear;

[0073] After the car enters, it passes through the slowdown & stop block and sends a signal to Station02 that it has fully entered;

[0074] The steering gear starts working, rotates 90 degrees to reach port B, and sends a command to the trolley to allow it to exit from port B, and the trolley starts;

[0075] The vehicle drives out of Exit B, passes through the deceleration and stop block, and after checking the QR code at the exit position, sends a signal to the cross steering gear to complete the exit; the cross steering gear returns to the Ready state;

[0076] The process flag inside the trolley is automatically set to Station02-OK, and the vehicle enters Station03;

[0077] The trolley starts running;

[0078] Customer's fully automatic assembly stand-alone unit (Station03):

[0079] The trolley moves to the left and enters the customer's automatic stand-alone machine. After passing the deceleration and stop block, the trolley stops at the designated position.

[0080] The built-in wireless interaction module of the trolley sends a positioning signal to the external wireless interaction module installed on the track. The external wireless interaction module sends a trolley ready signal to the client device through one output point.

[0081] The customer automatically starts the machine and runs it. When the specified assembly work is completed, a completion signal is sent to the car through an input point of the external wireless interactive module;

[0082] The process flag inside the trolley is automatically set to Station03-OK, and the trolley enters Station04 to start running the customer's fully automatic detection stand-alone (Station04):

[0083] The built-in wireless interaction module of the trolley sends a positioning signal to the external wireless interaction module installed on the track. The external wireless interaction module sends a trolley ready signal to the client device through one output point.

[0084] The customer automatically starts the machine and runs it. When the designated inspection work is completed, a completion signal is sent to the trolley through one input point of the external wireless interactive module, and an OK / NG signal is sent through the second input point.

[0085] The process flag inside the trolley is automatically set to Station04-OK or Station04-NG, and the vehicle enters Station05;

[0086] The trolley starts running;

[0087] Hoist (Station05):

[0088] The trolley moves to the left, passes the deceleration & stop block, and stops in front of the upper entrance A of the elevator;

[0089] At this time, the code reader inside the car is triggered to recognize the position code through the QR code and send a car arrival signal to the corner machine; for example, "Station05 upper entrance A request to enter";

[0090] After the hoist completes the previous action, it receives the signal "Station05 upper entrance A", moves the hoisting platform to the A entrance position, and issues a permission to enter command to the trolley;

[0091] The trolley receives the permission command from the upper port A of Station 05 and starts running into the upper level of the elevator;

[0092] After the trolley enters, it passes through the deceleration and stop block and sends a signal (trolley number + OK\NG) to Station05 indicating that it has completely entered. When the signal sent is an OK product signal, the elevator does not move and directly sends a signal to the trolley to allow it to exit. After receiving the signal, the trolley directly exits the elevator (B port). After exiting B port, the trolley passes through the deceleration and stop block and checks the QR code at the exit position.

[0093] Send a signal to the elevator to complete the exit; the elevator returns to the Ready state;

[0094] When the NG product signal is sent, the elevator track descends to the lower exit C and sends a permission signal to the trolley. After receiving the signal, the trolley drives out of exit B, passes the deceleration and stop block, and after checking the QR code at the exit position, sends a completion signal to the elevator. The elevator then returns to the upper Ready state.

[0095] The OK product car moves to the left and heads towards Station 06;

[0096] The NG exit trolley runs from the lower level to the right and heads towards Station 02;

[0097] 90-degree corner (Station06):

[0098] The car moves to the left, passes the deceleration & stop block, and stops before the entrance of the 90-degree corner;

[0099] At this time, the code reader in the car is triggered to recognize the position code through the QR code, and the car switches to the right turn mode once. The car starts and matches the speed of the left and right wheels. After turning right 90 degrees and exiting the corner, it automatically switches back to the normal driving mode Station05.

[0100] Subsequent operation of OK product trolley:

[0101] Referring to the above operation method, after the OK product trolley continues to pass through Station 07-Station 10, operator B removes the finished product from the trolley at Station 10 and presses the start button, and the trolley re-enters Station 01. At this time, the trolley status record flag is cleared, and the subsequent operation of the NG product trolley at Station 05 is restarted from Station 01:

[0102] Referring to the above operation method, the NG product trolley continues to pass through Station 02 and Station 11 and returns to the upper level and enters the maintenance station Station 12;

[0103] Subsequent operation of the accidental NG car:

[0104] If the trolley fails unexpectedly at any station, you can manually empty the trolley material and move the trolley to Station 01.

[0105] After cleaning the trolley and confirming, press the trolley start button again. The trolley will then run again and restart recording from Station 01. Alternatively, manually press and hold the Bypass button on the trolley to set the current trolley to Bypass mode. The trolley will continue to run along the predetermined route, but no operations will be performed on any station during the operation. It will flow to Station 10. At Station 10, operator B will remove the waste (if any) from the trolley. After cleaning the trolley and confirming, press the start button again. The trolley will then re-enter Station 01. At this point, the trolley status record flag will be cleared and recording will restart from Station 01.

[0106] Magnetic grid precise positioning:

[0107] After the car passes the deceleration & stop block and detects the QR code at the entrance of the magnetic scale, it switches to the fast positioning mode;

[0108] According to the stop position bound to the QR code, the trolley quickly moves to the designated position by detecting the pulse of the magnetic grid and enters the position holding state. The trolley continuously adjusts its position in real time to ensure position accuracy. (At this time, if an external force moves the trolley out of the current positioning position, the trolley will return to the designated position after releasing it.) The built-in wireless interaction module outputs the trolley arrival signal, and the external wireless interaction module simulates the detection of the signal and triggers the required production action. After completion, it sends a completion signal to the trolley, and the trolley starts to continue running.

[0109] Simulate\Run:

[0110] In the project management interface, you can add components that need to be configured to the interface window by adding components;

[0111] Set station names for components according to the car's operation logic, such as Station01, Station02..., and drag and drop them to appropriate layout positions;

[0112] Components are connected by arrow lines, and the direction of the arrow is the direction of the trolley's movement;

[0113] Click on a component and a property bar will appear on the right side of the window, where you can set interaction rules, trigger requirements and all other possible editing options;

[0114] After the connection is completed, by setting parameters such as track length, overall running speed, NG rate, etc., click the simulation button to simulate the current program and calculate the simulated running beat and beat bottleneck position;

[0115] After the simulation is correct, click the Save and Run button, and the software will automatically switch to the real-time status interface;

[0116] Real-time status:

[0117] In real-time mode, the main interface will present the layout of the simulation interface and display the current working status of each component through dynamic effects;

[0118] To ensure the real-time operation of components, the wireless interaction module will prioritize information exchange between components, and only conduct information exchange between components and the host computer when it is idle;

[0119] In real-time mode, switch to the project management interface and make limited online parameter changes to the current project, such as running speed, delay time, interactive signal, etc. Parameters that cannot be changed are displayed in gray and cannot be selected.

[0120] After modification, you can also click the Simulate button to confirm the simulation. After confirmation, click the Run button again. The new configuration will change the default settings of each component through the wireless network.

[0121] Multi-model production:

[0122] This system supports multi-model mixed production by assigning different trolleys and different components and workstations to

[0123] For a certain product and production process, the production function will be triggered only when the relevant trolley runs to the relevant components and workstations.

[0124] If there is no match, it enters the Bypass mode and drives in and out directly without triggering the production function;

[0125] Clear line function: click the Clear line button on the host computer, the production line will continue the current production action until all the carts that have passed through Station 01 have completed all normal processes. However, the carts that have re-flowed to Station 01 will enter the Bypass mode until all the carts have completed emptying the materials and stopped in front of Station 01 in sequence according to the laser sensor of the carts. At this time, the entire system can be powered off.

[0126] Power-off retention:

[0127] Power-off retention includes the power-off retention of the host computer and the power-off retention of each component;

[0128] Host computer power off retention:

[0129] The host computer saves all running data in real time to the database of the local hard disk. If there is a sudden power outage during operation, the running data will be automatically restored from the database of the local hard disk when the power is turned on again, and the operation can continue;

[0130] Power-off retention of each component:

[0131] The MCU control board of each component writes the current data to the MCU's Flash in real time during operation. After power is restored, the current operation will continue. If the amount of data is too large, the onboard button battery RTC is used to prevent data corruption caused by sudden power failure of the controller.

[0132] Summary of component operation modes:

[0133] Based on the above examples, we can roughly summarize the operation modes of the main control programs of each component:

[0134] The switching of the operating mode is completed by the QR code structure wireless interaction module. The QR code is read by the built-in code reader of the car. The reading time is when the car stops by the deceleration block. It does not work at other times. There are two interaction opportunities for the wireless interaction module. When wireless interaction is required after the QR code is detected, the interaction between modules is given priority. When the car completes the high-priority interaction, the interaction between the module and the host computer can be carried out.

[0135] Power-on standby mode: Press the trolley power switch, and it will automatically enter the standby mode. At this time, the display screen shows that it is in the standby mode, the running direction is forward, and the status of proximity switch 3 is ON (the trolley is on the track);

[0136] The fan does not work. The trolley can switch the running direction through the button and can be started through the button. When the trolley starts, the fan and the light strip are turned on;

[0137] Forward running: The trolley accelerates from a standstill to the maximum set running speed and maintains the running. When the laser in front detects that the distance from the trolley in front is less than the set value a, the trolley starts to decelerate; when the distance is greater than the set value a, the trolley accelerates to the maximum set running speed; when the distance is less than the set value b (0 < b < a), the trolley stops. When the distance gradually increases to > b, the trolley starts to run slowly. When the distance gradually increases to > a, the trolley accelerates to high speed;

[0138] During the running, when proximity switch 1 and proximity switch 2 detect signals in sequence (not simultaneously), the trolley enters the low-speed running; when proximity switch 1 and proximity switch 2 detect signals simultaneously, the trolley stops immediately;

[0139] Reverse running: The running direction of the trolley is switched from forward to reverse, and at the same time, the laser sensor switches from forward effect to reverse effect, and other functions are the same as those in the forward direction;

[0140] Magnetic grating precise positioning:

[0141] The trolley starts and runs at high speed. When the number of pulses at the specified position a - the number of pulses detected by the magnetic grating ruler b < c (c > 0 and can be adjusted), the trolley decelerates to low speed until a - b = 0, and then the trolley stops. At this time, it can send out a signal indicating arrival, and at the same time, the trolley keeps its position and continuously keeps a - b dynamically at 0; when the external completion signal is sent, the trolley starts and enters the running state in the current running direction, that is, forward running / reverse running;

[0142] When the trolley needs to enter multi-position positioning on the same magnetic grating ruler, the above process is repeated; when all positioning is completed, the trolley starts to run and exits the current magnetic grating ruler range;

[0143] When there is already a trolley working at the specified position of the magnetic grating ruler, the later-entering trolley stops and starts automatically according to the laser detection distance to avoid collision;

[0144] Ninety-degree corner running:

[0145] The trolley starts for a distance a and enters the corner unit. At this time, the inner motor switches to low speed V1, and the outer speed switches to low speed V2, and V2 > V1 (if turning to the other side, then V2 < V1); after running for a certain time T1, the trolley resumes the normal speed and continues to run forward;

[0146] When there is already a car working in the corner, the car entering later will automatically stop and start according to the laser detection distance to avoid collision;

[0147] Cross corner machine:

[0148] Upper layer zero position calibration: the stepper motor cooperates with the rotating magnetic scale and U-shaped photoelectric to calibrate the zero position of the lower turntable;

[0149] Upper level hold: Set the upper level default entrance position to A, the trolley enters and exits in the same direction, and the upper level turntable does not move;

[0150] Upper level left turn: After the trolley enters, the upper level turntable turns left 90 degrees, and after the trolley exits, the turntable returns to position A;

[0151] Upper level right turn: After the trolley enters, the upper level turntable turns right 90 degrees, and after the trolley exits, the turntable returns to position A;

[0152] Upper level reversal: After the trolley enters, the upper level turntable turns right 180 degrees, and after the trolley drives out in the opposite direction, the turntable returns to position A;

[0153] Lower layer zero position calibration: The stepper motor cooperates with the rotating magnetic scale and U-shaped photoelectric to calibrate the lower layer turntable 0 position;

[0154] Lower level hold: Set the default entrance position of the lower level to B, the trolley enters and exits in the same direction, and the lower level turntable does not move;

[0155] Turn left on the lower level: After the trolley enters, the lower turntable turns left 90 degrees, and after the trolley exits, the turntable returns to position B;

[0156] Turn right on the lower level: After the trolley enters, the lower turntable turns right 90 degrees, and after the trolley exits, the turntable returns to position B;

[0157] Lower level reversal: After the trolley enters, the lower level turntable turns right 180 degrees, and after the trolley drives out in the opposite direction, the turntable returns to position B;

[0158] Any rotation angle can be set, multiple angles, the principle is the same;

[0159] Hoist:

[0160] Bottom 0 position calibration: lower the lifting platform to the lowest point, and enter the height 0 position calibration through the position sensor and magnetic scale;

[0161] Upper hold: Set the upper default entrance position to HA, the trolley enters and exits in the same direction, and the elevator does not move;

[0162] Enter from the upper level and exit from the lower level: After the trolley enters from the upper level HA, the elevator descends to the lower level HB and stops, and the trolley exits;

[0163] Enter from the lower level and exit from the upper level: After the trolley enters from the lower level HB, the elevator descends to the upper level HA position and stops, and the trolley drives out;

[0164] Lower level hold: the lifting platform descends to the lower level HB height, the trolley moves in and out in the same direction, and the hoist does not move;

[0165] Any stop position can be set, multiple positions, the principle is the same;

[0166] In summary, when the dual-track all-electric intelligent conveying and closed-loop monitoring and scheduling system is used, first, operator A 8 continuously loads the working smart track car 4, and the working smart track car 4 moves toward the cross-corner machine 10; the working smart track car 4 moves to the cross-corner machine 10, and the cross-corner machine 10 makes the working smart track car 4 turn ninety degrees, and then moves toward the assembly and testing unit 11; after the working smart track car 4 completes product assembly and testing on the assembly and testing unit 11, it moves out toward the first elevator 12; the working smart track car 4 marked as OK continues to move along the upper level to the cache workshop 1 after passing the first elevator 12; the working smart track car 4 marked as NG is lowered from the working smart track car 4 to the lower track and moves toward the cross-corner machine 10, passes the lower level of the cross-corner machine 10, and moves to the second elevator 13. The second elevator 13 returns to the upper level, and the product is repaired and inspected again by operator C 9. The working smart rail car 4 marked as NG passes through the upper level of the cross-corner machine 10 again and moves to the assembly test unit 11, thus entering the assembly test; the working smart rail car 4 marked as OK enters the cache workshop 1 after passing the corner. If a working smart rail car 4 is aged, the products on the surface of the aged working smart rail car 4 will be transferred to the spare smart rail car 5 in the cache workshop 1, and the spare smart rail car 5 will return to the double-track track 2 for movement. After removing the products, the aged working smart rail car 4 moves along the second upper track 304 to the preset position to wait for maintenance personnel to inspect it; the non-aged working smart rail car 4 and the spare smart rail car 5 after transferring the products move along the double-track track 2 to operator B 7, and operator B 7 takes the finished products off the smart rail car; the empty car continues to move to the right, passes the corner structure and moves to operator A 8, and operator A 8 loads the materials again, thus completing a production cycle.

[0167] like Figure 7-12 As shown, specific reference Figure 12 , this system includes the following contents:

[0168] After setting QR code label 2 as the starting point, the trolley must be placed between QR code labels 1 and 2. Otherwise, an error will be reported at the QR code label. The error reporting method can be set to wait for manual processing, or the current trolley status can be set to NG and the current process can be continued (the NG product processing logic is not shown in the current example. The default for OK products and the operation interface for NG products need to be included in the property settings of each component);

[0169] In this example, click the logic icon in turn and set the properties of each component according to the table below (for example, the entrance and exit codes A, B, C, and D are temporary example codes, and each layer has four directions: A, B, C, and D);

[0170] according to Figure 12 As defined in the system, the car can travel indefinitely in this system;

[0171] The operating logic of the trolley, corner machine, and elevator itself already exists in the control panel of the main body. The function of the upper computer is to create the sequence and association between them, that is, to schedule the operation of each functional component and monitor its operating status;

[0172] The system also has a simulation run function. When the configuration is completed, click Simulate Run and set the number of carts to be put in. The configuration interface will display the running status and position of the cart in 2D animation. The non-current layer will be represented by grayscale animation.

[0173] After hiding the logic interface, the configuration interface can be divided into multiple windows according to the layering, and the operating status of different layers can be displayed with the status of the current layer (colored status);

[0174] By setting the product quantity of each cart, the beat of each node and the production capacity of the entire line can be automatically generated.

[0175] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed form; many modifications and changes will be apparent to those skilled in the art; the embodiments are selected and described in order to better illustrate the principles and practical applications of the invention and to enable those skilled in the art to understand the invention and thereby design various embodiments with various modifications suitable for specific purposes.
