[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in 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 creative work are within the scope of protection of the present invention.

[0048] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0049] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0050] An intelligent piano key selection system, such as Figure 1 As shown, including

[0051] Control module 1, connected to the glass transmission system, used to read the glass information in the glass transmission system in real time;

[0052] The key module 2 includes a plurality of keys (key a, key b ... key n), and position sensors are provided on the keys;

[0053] The ASI component 3 is connected to the control module 1 and the position sensor respectively, and is used to collect the feedback signal of the position sensor and transmit the feedback signal to the control module 1;

[0054] The key execution module 4 is connected to the control module 1 and the key module 2 respectively. Under the action of the control module 1 , the key execution module 4 drives the keys to rise and fall through the motor 42 .

[0055] Specifically, the present invention provides an intelligent key selection system, which is applied to the rolled glass production line. The control module 1 cooperates with the ASI component 3 and the key execution module 4, and can adjust the appropriate action timing of the key module 2 according to the glass specifications to meet the production needs. It has an abnormal emergency interlocking mechanism, reduces manual intervention, protects production equipment, and ensures product quality.

[0056] In a preferred embodiment, the ASI component 3 includes:

[0057] IO slave station 31, connected to the position sensor, for collecting feedback signals;

[0058] An ASI bus master station 32 is connected to the control module 1 and the IO slave station 31 and is used to transmit feedback signals to the control module 1;

[0059] The ASI battery 33 connects the ASI bus master station 32 and the IO slave station 31.

[0060] Specifically, ASI (Actuator Sensor Interface) is a communication protocol in industrial automation that simplifies and reduces the complexity of wiring and communication between sensors and control systems. Through this protocol, sensors and actuators can directly exchange data with the control system, thereby improving the efficiency and reliability of the automation system.

[0061] IO slave is a device responsible for input and output signal acquisition and control. In this embodiment, multiple IO slaves 31 are specifically provided: IO slave 31a, IO slave 31b, IO slave 31c...IO slave 31n, which are used to collect sensor information on the keys. The feedback signal of the position sensor will be processed by the IO slave 31 and transmitted to the upstream ASI bus master 32.

[0062] The IO slave station 31 can collect feedback signals from the position sensor in real time, ensuring that the system can accurately control the position changes of each key during the production process and provide real-time data for the control module 1.

[0063] Centralizing the collection and transmission functions of the feedback signal in the IO slave station 31 can simplify the electrical connection and signal processing process and reduce the complexity of the control system.

[0064] Data is transmitted via the ASI bus, saving space, and the IO slave 31 can ensure data stability and reliability.

[0065] The ASI bus master 32 is connected to the control module 1 and the IO slave 31, and acts as the master control center. Its main task is to receive feedback signals from the IO slave 31 and transmit these signals to the control module 1 for the latter to process and analyze.

[0066] The ASI bus master 32 is responsible for coordinating the data flow of the entire system to ensure smooth information transmission between modules.

[0067] In addition, the ASI bus master station 32 can also configure the IO slave station 31 according to actual needs to ensure efficient operation of the system.

[0068] The ASI bus master station 32 can quickly and accurately obtain the feedback signal from the IO slave station 31 through the ASI bus, and adjust the action of the key execution module 4 accordingly to ensure real-time control in the production process.

[0069] ASI bus technology is a mature industrial communication protocol with high reliability, anti-interference ability and good scalability, and is suitable for use in complex production environments.

[0070] The ASI battery 33 provides backup power for the ASI bus master 32 and IO slave 31. When the normal power supply fails, the ASI battery 33 can provide continuous power to these important components to ensure that the normal operation of the system is not interrupted.

[0071] The working principle of ASI Battery 33 is that when the main power supply is interrupted or the voltage fluctuates, ASI Battery 33 can automatically take over the power supply to ensure the continuity of data transmission and system control.

[0072] In a preferred embodiment, the key execution module 4 includes:

[0073] The key driving unit 41 is connected to the control module 1 and sends a driving signal under the action of the control module 1;

[0074] The motor 42 is connected to the key driving unit 41 and provides power to the key module 2 according to the driving signal.

[0075] Specifically, the key driving unit 41 converts the driving signal (such as the change of current or voltage) sent by the control module 1 into a specific control signal required by the motor 42. The motor 42 can correctly start, stop or adjust the motion state according to the instruction of the control module 1.

[0076] The key driving unit 41 adjusts the speed, direction and other parameters of the motor 42 according to the instructions of the control module 1, so as to accurately control the up and down movement of the keys.

[0077] The key drive unit 41 may also have some built-in protection mechanisms, such as overload protection, short circuit protection, etc., to prevent the motor and the entire system from being damaged under abnormal circumstances.

[0078] It includes a plurality of motors 42 (motor 42a, motor 42b ... motor 42n) and a plurality of key drive units 41 (key drive unit 41a, key drive unit 41b ... key drive unit 41n), one motor 42 corresponds to one key drive unit 41. The motor 42 drives the key module 2 to rise or fall by rotating mechanical parts (such as gears, belts or levers, etc.). The up and down movement of the key is to cooperate with the glass transmission system to perform functions such as film selection and transmission.

[0079] The speed and position control of the motor 42 will affect the movement accuracy of the keys. By precisely controlling the operation of the motor 42, the system can ensure the lifting accuracy of the keys, thereby ensuring the accuracy and reliability of the glass transmission process.

[0080] The combination of the key drive unit 41 and the motor 42 makes the entire key lifting process highly automated, reducing manual operations and thus improving production efficiency. By precisely controlling the operation of the motor 42, the lifting of the key can be precisely adjusted according to production needs, ensuring smooth transmission and processing of glass on the production line.

[0081] Since the key drive unit 41 can finely control the motor 42, the system can prevent faults such as overload and overheating, thereby extending the service life of the equipment.

[0082] The system can automatically adjust the timing of key movements based on real-time data, reducing human intervention and the risk of operational errors.

[0083] It can precisely control the movement of the keys, ensure accurate selection and delivery of glass sheets, reduce quality problems caused by equipment errors during the production process, and ensure high-quality output of products.

[0084] In a preferred embodiment, the control module 1 is a programmable logic controller;

[0085] The control module 1 is connected to the glass transmission system via the Profinet communication protocol. Profinet is an automation bus standard based on Ethernet technology.

[0086] Specifically, the Profinet communication protocol supports high-speed and real-time data transmission. Through Profinet, the control module 1 can read the glass information in the glass transmission system in real time, respond quickly and control other components (such as the key execution module 4) to perform corresponding actions.

[0087] Profinet protocol is an industrial-grade network communication standard that supports multiple devices connected via Ethernet, ensuring that multiple devices can communicate and collaborate with each other. It solves the complexity of multi-device connection and data exchange, and ensures coordination and information flow between different modules.

[0088] Through Profinet, the control module 1 can efficiently and stably exchange data with the glass transmission system. Since Profinet supports lower network latency, it can monitor and control equipment in real time during the production process, reducing problems such as low production efficiency or untimely system response caused by communication delays.

[0089] Profinet supports flexible network topologies, including star and bus topologies, and has good scalability. As production needs increase, the system can flexibly add new devices or modules without being restricted by the network structure.

[0090] The Profinet protocol supports redundancy mechanisms (such as ring network topology), which can provide backup paths when equipment or network failures occur to ensure that the system continues to operate. This reduces potential downtime and ensures smooth production and safe operation of equipment.

[0091] The Profinet protocol is based on industrial Ethernet and has good compatibility. It can communicate with other common automation protocols (such as Profibus, Ethernet / IP, etc.), making system integration easier and enabling seamless connection between different devices and systems.

[0092] In a preferred embodiment, an industrial gateway 5 is also included, which is respectively connected to a manufacturing execution system 6 (MES, Manufacturing Execution System) for storing and analyzing data and the control module 1 through the OPC communication protocol.

[0093] Specifically, the industrial gateway 5 is used to realize data exchange and information transmission between different devices and modules, especially the communication between the control module 1 and the manufacturing actuator 6. The industrial gateway usually uses the OPC (OLE for Process Control) protocol to transmit and exchange data, so that different types of industrial equipment and systems can be interconnected. OPC is an industrial communication protocol used to realize data exchange between different devices and control systems.

[0094] The industrial gateway 5 can connect the control module 1 and the manufacturing actuator 6 through the OPC protocol, so that these devices and systems can seamlessly exchange data. It provides an intermediary layer to bridge the communication between different devices and systems.

[0095] Manufacturing Execution System 6 is a system used to manage and monitor the production process, and to monitor, schedule and optimize the equipment, processes, personnel and materials in real time during the production process. MES is a system used to manage and monitor the production process, and is used to provide real-time control of production activities. As an important tool for industrial production management, MES can provide many key data in the production process to help enterprises optimize production efficiency, reduce costs and improve product quality.

[0096] The MES system can collect data from various devices and modules, such as control module 1, in real time, monitor the production process, and effectively track the production process and status of each piece of glass, thereby ensuring the traceability and stability of the production process.

[0097] MES can not only process production data in real time, but also store the data in a database for subsequent analysis and report generation. By analyzing historical data of the production process, MES can identify potential production bottlenecks and efficiency issues, thereby providing data support for improvement and optimization.

[0098] Combining Industrial Gateway 5 and MES, it is possible to coordinate various production links in real time, avoid information lag and erroneous transmission in production, and ensure the efficiency of the production process.

[0099] Through automated data collection, analysis, and scheduling, MES can reduce manual intervention and errors and improve the accuracy and stability of the production process.

[0100] The industrial gateway 5 transmits feedback signals in real time to ensure that the control module 1 can quickly respond to abnormal situations in production, thereby protecting production equipment. At the same time, the continuous analysis of production data by MES can help identify and correct quality problems that may occur in the production process.

[0101] The MES system can comprehensively record production data, help managers understand production status at any time, provide production reports and analysis, and help decision makers make more appropriate adjustments and decisions.

[0102] The manufacturing execution unit 6 is used to effectively store production data and realize functions such as data tracing, analysis and fault prediction.

[0103] Classify the reasons for each equipment action, the equipment status and operation records, integrate this information, use an independent gateway to integrate with the MES system with the help of OPC technology, package the classified data and send it to the MES system, so that real-time production information can be effectively stored, traced and analyzed, which is the basis of intelligent predictive maintenance.

[0104] In a preferred embodiment, a touch screen 7 is further included, which is connected to the ASI component 3, the control module 1 and the key execution module 4 respectively, and the touch screen 7 is used to display and control the keys.

[0105] Specifically, the touch screen 7 visualizes the status of all keys. Parameters can be set, modes can be switched, a certain key can be controlled individually, and any one or more keys can be temporarily shielded so that they do not participate in automatic control and do not affect normal production. Operation and maintenance are more flexible and convenient.

[0106] The present invention further optimizes the control process of the traditional piano-key glass selection device. The action execution timing of the equipment is adjusted autonomously according to the characteristics of different glass specifications. The status of the equipment is collected using the remote IO method of the ASI bus, saving installation costs. The abnormal conditions of the equipment are identified and classified to execute the interlocking protection mechanism. The matching touch screen 7HMI interface is animated, visualized, and easy to operate. Communication is established with the MES system, production data is uploaded in real time, and information is fully traceable.

[0107] The key selection device has many control actuators, feedback signals and adjustable mode parameters. The touch screen 7 is installed near the device, and the human-machine interface of the device is visualized and the operation is more flexible. The human-machine interface needs to display the position status and alarm of each key, develop necessary process parameters, and perform convenient operations such as forced shielding, mode switching, and inching for each key.

[0108] A control method for an intelligent piano key selection system, referring to Figure 2 , used to control the intelligent piano key selection system, including a piano key action control method, the piano key action control method includes,

[0109] Step S1, reading glass information of upstream glass through control module 1, the glass information includes glass plate length and transmission speed;

[0110] Step S2, determining whether the length of the glass sheet is less than a preset process value, if yes, executing step S5, if no, executing step S3;

[0111] Step S3, judging whether the upstream glass has completely entered the intelligent piano key selection system, if yes, executing step S5, if no, executing step S4;

[0112] Step S4, judging whether the upstream glass has reached the limit position of the key execution action, if yes, executing step S5, if no, keeping the key posture unchanged;

[0113] Step S5, judging whether the downstream glass has completely left the intelligent piano key selection system, if so, controlling the piano key to perform an action, if not, keeping the posture of the piano key unchanged.

[0114] Specifically, the present invention also provides a control method for an intelligent piano-key selection system, which, based on the conventional functions of the piano-key selection device in the cold-end cutting section of the float and rolled glass production line, helps to make production lean and intelligent. It is committed to fully considering the external disturbance factors of the system, taking effective identification measures for various abnormal working conditions, designing corresponding emergency strategies, strengthening the system's adaptability to disturbances, reducing glass losses, and improving system stability.

[0115] Establish a more complete standard network communication interface for the key selection system, wire control system and MES system, sort the incoming panel information read from the wire control system, calculate the optimal action execution time for different types of glass, monitor and feedback the working status of each key in real time during the equipment execution process, identify various common abnormal working conditions, and execute emergency chain strategies based on the identified abnormalities.

[0116] In addition, the reasons for each equipment action are broken down and the data is uploaded to the MES system in real time to complete data archiving and traceability, which improves the automation and intelligence level of the equipment, reduces the difficulty of equipment operation and maintenance, and reduces glass loss and equipment damage.

[0117] An upper limit switch and a lower limit switch are provided on the keys, and the upper limit switch and the lower limit switch send switch feedback signals respectively to realize the monitoring of the execution process of the equipment.

[0118] The control module 1 autonomously adjusts the timing of executing actions for glass of different specifications based on the read glass specifications; the glass information includes the length, width, thickness and transmission speed of the glass plate, and the preset process values ​​are set according to actual production needs.

[0119] The control module 1 autonomously adjusts the execution action position according to the read transmission speed; it can identify a variety of abnormal situations, and execute corresponding emergency protection chain actions for different abnormal situations to protect equipment and maintain production continuity.

[0120] Reference Figure 4 , when the plate length is less than the process value, it is only necessary to determine whether the downstream glass has been separated from the key device. If the downstream glass has been separated, the key can be controlled to perform the action immediately, and if it has not been separated, the key can maintain the posture;

[0121] When the board length is greater than the process value, it is necessary to first determine whether the glass has completely entered the key device. If it has completely entered and the downstream glass has been detached, the key action will begin. If it has not completely entered the key device, it is necessary to determine whether it has reached the limit position.

[0122] If it reaches the target and the downstream glass has been detached, the action will be executed. If it does not reach the target, the posture will be maintained.

[0123] The extreme positions of the key actions can be automatically adjusted according to the transmission speed read in real time.

[0124] In a preferred embodiment, step S2 further includes:

[0125] Determine whether the transmission speed has changed, if so, adjust the limit position of the key execution action, if not, the limit position of the key execution action remains unchanged.

[0126] In a preferred embodiment, referring to Figure 3 , also includes abnormal emergency chain method, abnormal emergency chain method includes,

[0127] Step G1, combining and partitioning a plurality of piano keys according to glass information to obtain a plurality of piano key groups;

[0128] Step G2, controlling the motor 42 to move according to the target position of the keys in the key group, and determining whether the position sensor senses the first position signal, if yes, controlling the motor 42 to stop working, if no, executing step G3;

[0129] Step G3, determining whether the first position signal feedback is timed out, if yes, issuing a first position signal timeout alarm and controlling the motor 42 to continue working, and then executing step G4, if no, returning to executing step G2;

[0130] Step G4, determining whether the position sensor senses the second position signal, if yes, controlling the motor 42 to stop working, if no, executing step G5;

[0131] Step G5, determining whether the second position signal feedback times out, if yes, controlling the motor 42 to stop working, if no, returning to executing step G2.

[0132] In a preferred embodiment, the first position signal and the second position signal are in opposite directions;

[0133] The first position signal is an upper limit signal or a lower limit signal;

[0134] The second position signal is an upper limit signal or a lower limit signal;

[0135] When the second position signal in step G5 is an upper limit signal, when the second position signal times out, the motor 42 is controlled to stop working and all the keys in the key group are lifted. When the second position signal is normally fed back, the process returns to step G2.

[0136] Reference Figure 5 , is a specific implementation method of the abnormal emergency chain method in an embodiment,

[0137] Step 1, combining and partitioning a plurality of piano keys according to glass information to obtain a plurality of piano key groups;

[0138] Step 2, when the key in the key group needs to rise, the motor 42 is controlled to rise, and it is determined whether the position sensor senses an upper limit signal. If yes, the motor 42 is controlled to stop working, if not, step 3 is executed;

[0139] Step 3, determining whether the upper limit signal feedback is timed out, if yes, issuing an upper limit signal timeout alarm and controlling the motor 42 to continue working, and then executing step 4, if no, returning to executing step 2;

[0140] Step 4, determining whether the position sensor senses a lower limit signal, if yes, controlling the motor 42 to stop working, if no, executing step 5;

[0141] Step 5, determine whether the lower limit signal feedback timeout, if yes, control the motor 42 to stop working, if not, return to step 2.

[0142] The implementation method of the abnormal chain mechanism in the reverse direction is as follows:

[0143] Step (1), combining and partitioning a plurality of piano keys according to glass information to obtain a plurality of piano key groups;

[0144] Step (2), when a key in the key group needs to be lowered, the motor 42 is controlled to descend, and it is determined whether the position sensor senses a lower limit signal. If yes, the motor 42 is controlled to stop working, and if not, step (3) is executed;

[0145] Step (3), determining whether the lower limit signal feedback has timed out, if so, issuing a lower limit signal timeout alarm and controlling the motor 42 to continue working, and then executing step (4); if not, returning to executing step (2);

[0146] Step (4), determining whether the position sensor senses an upper limit signal, if yes, controlling the motor 42 to stop working, if no, executing step (5);

[0147] Step (5), determine whether the upper limit signal feedback timeout, if yes, control the motor 42 to stop working and lift all the keys in the key group, if no, return to step (2).

[0148] Specifically, each key is regarded as an independent unit, and after different abnormalities are determined, a unified safety interlocking principle is implemented:

[0149] The glass enters the key selection device, and the system determines the target position of the key based on the glass information. When the key needs to be controlled to rise, if the upper limit switch feedbacks within the normal time range, the motor 42 is controlled to stop. If the upper limit switch feedback times out, an alarm is sounded and the motor 42 continues to be controlled to operate.

[0150] If the lower limit switch feedbacks within the normal time range, the motor 42 is controlled to stop, so that the keys stop at the lower limit position without hindering production. If the lower limit switch also times out without feedback, an alarm is issued and the motor 42 is stopped immediately. At this time, the stop position of the motor 42 cannot be determined, so all the keys in the same group are lifted and the descending action is no longer performed.

[0151] The present invention can automatically adapt to the transmission characteristics of glass of different specifications according to the collected glass information, flexibly control the timing and movement trajectory of the action of the mechanism, and avoid damage to the glass or even the equipment caused by simple and rough equipment actions.

[0152] In addition, equipment status identification measures have been added to respond to different abnormal situations with emergency chain actions to protect equipment, and a standard communication interface has been established with the MES system. The system makes detailed classifications based on the reasons for film selection, archives manual operation records into logs with standard templates, and sends them to the MES system in real time. Production managers can query and trace the equipment usage process and status in any time period to realize intelligent information management of production.

[0153] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
