[0027] 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.

[0028] 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.

[0029] 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.

[0030] Example:

[0031] An industrial automation equipment testing experimental platform, the experimental platform includes a human-machine interaction interface, a PLC and a variety of controlled devices;

[0032] The human-computer interaction interface is used to input different operating parameters into the PLC; it is also used to display the results sent by the PLC;

[0033] PLC is used to send the received different operating parameters to the corresponding controlled devices respectively, and collect the output parameters of the corresponding controlled devices in real time, detect whether each controlled device is faulty according to the output parameters, and send the result to the human-computer interaction interface.

[0034] Specifically, this embodiment can simulate the on-site equipment environment and can also perform program testing, thereby optimizing the production process.

[0035] You can also use two PLCs, models S7-1500 and S7-1200, such as Figure 2As shown in the figure, when different devices need to be linked and controlled, communication between two PLCs is required. The experimental platform uses two different specifications of PLCs, 1200 and 1500, for communication. Click the 1200 communication button on the human-computer interaction interface to send control instructions to the 1500PLC, and then send the command to the 1200PLC through the put / get protocol. The 1200PLC that receives the command activates its own control signal Q0.0, and the screen displays a green circle. At the same time, the hardware point Q0.0 of the 1200PLC also outputs a signal and lights up the status indicator. Through the linkage control of multiple PLCs, it is possible to control multiple devices in one operation interface, further optimize the production process, reduce the number of operators, improve equipment automation, and reduce human errors. S7-1200 can accurately back up and record the real-time data generated to ensure that each key data can be effectively stored. The recording and backup of real-time data provides a comprehensive monitoring method for the production and operation of the equipment, and can capture abnormal situations that may occur in the production process in a timely manner.

[0036] It also includes a PSU8600 smart power supply, which is used to power the equipment. The voltage and current requirements of each part can be adjusted through the knob on the panel. The PSU8600 smart power supply also has a short-circuit protection function. When the short-circuit fault is resolved, the power can be turned on again through the button on the PSU8600 smart power supply. The experimental platform can realize the power monitoring of the system, and can also monitor the fluctuation value when the system power fails. Realize the control and management of the system energy.

[0037] With the human-machine interface, the operating status of each part of the equipment can be intuitively monitored in real time, which can facilitate maintenance personnel to quickly determine the location of the fault point. The human-machine interface can also display whether the equipment is disconnected.

[0038] Limit the composition of the controlled equipment: the controlled equipment includes the servo motor system and the io-link system;

[0039] The human-computer interaction interface is used to input operating parameters to the PLC; it is also used to send test data to the PLC; it is also used to display the results sent by the PLC;

[0040] PLC, used to receive startup parameters, output control instructions to the servo motor system, control the speed, position and torque of the servo motor system, and collect the operating parameters of the servo motor system in real time, detect whether the servo motor system is faulty according to the operating parameters, and send the result to the human-computer interaction interface;

[0041] It is also used to send the received detection data to the io-link system, control the output data of the io-link system, and collect the output data of the io-link system in real time, detect whether the io-link system is faulty based on the output data, and send the result to the human-computer interaction interface.

[0042] Specifically, the servo motor system can achieve precise control through the human-machine interface, and can adjust parameters to ensure the safe operation of the equipment. The io-link system simplifies the electrical wiring of industrial sites and improves flexibility and stability.

[0043] Servo motors are extremely important actuators in modern automated control systems. They are widely used in various high-demand industrial scenarios because they can accurately control position, speed, and torque. The high precision of servo motors enables them to achieve micron-level position control in complex motion control, ensuring high consistency and high quality of products during processing. This high-precision feature makes servo motors particularly suitable for scenarios that require precise positioning, such as CNC machine tools, robots, automated assembly lines, etc.

[0044] This experimental platform uses the Siemens V90 servo system, which is a servo drive solution with superior performance and wide application. The V90 servo system consists of two parts: the frequency converter and the servo motor. The frequency converter is responsible for converting the input electrical energy into the control signal required by the servo motor, and realizes precise control of the motor through the closed-loop control algorithm. This closed-loop control can not only monitor and adjust the operating status of the motor in real time, but also respond quickly when an abnormality occurs in the equipment to avoid equipment damage or production interruption.

[0045] The application of V90 servo system in the experimental platform makes the motion control system of the entire platform extremely flexible and reliable. The experimental platform can realize a variety of complex control modes through this servo system, such as speed control, position control and torque control. Users can adjust the operating parameters of the servo motor online through the human-machine interface (HMI), monitor the working status of the motor in real time, and quickly locate the problem and take corresponding measures when the system fails.

[0046] like Figure 3 As shown in the figure, through the human-computer interaction interface, users can easily perform various control operations on the servo motor, including forward and reverse speed control, absolute position control and relative position control. The interface design is intuitive, and users can easily set the motor's operating parameters, such as speed and position, according to specific needs. This flexible control method is not only suitable for different industrial application scenarios, but also can meet diverse experimental needs, providing operators with a high degree of operational freedom and accuracy.

[0047] During the operation of the motor, the system can also monitor and display the key operating parameters of the motor, such as current, torque, speed and position, in real time. Real-time monitoring of these parameters enables operators to quickly understand the actual working status of the motor, discover and deal with possible problems in a timely manner, and ensure the safe and stable operation of the equipment. At the same time, the collection and analysis of these data also provides an important basis for further optimizing the motor control strategy, improving the efficiency and reliability of the entire automation system.

[0048] In practical applications, servo motors need to adjust parameters according to the specific requirements of mechanical action. Through the human-machine interface, operators can set multiple functions including position zeroing, torque limiting and soft limit switches. These settings ensure that the servo motor operates under conditions that meet the mechanical parameters, thereby ensuring the safety and stability of the equipment. For example, the position zeroing function can ensure the accuracy of the motor's initial position, the torque limiting function prevents excessive load from damaging the motor, and the soft limit function prevents the motor from exceeding the set safety range.

[0049] When a servo motor fails, the human-machine interface will automatically display the relevant fault code to help the operator quickly identify the problem. After the fault is eliminated, the operator can clear the alarm information through the reset function on the interface and restore the normal operation of the motor. This fault diagnosis and handling mechanism enables the equipment to be quickly resolved when problems occur, thereby reducing downtime and ensuring the continuity and efficiency of the production process.

[0050] The io-link system can control the actuator and provide real-time feedback on the status of the actuator. Under the io-link master station, you can connect to exclusive modules such as io-link digital input and output slaves, io-link analog input slaves, io-link analog output slaves, and io-link valve islands. These modules have IP68-level protection effects, which facilitates the direct deployment of modules to industrial sites without special protection. At the same time, the io-link master station can directly execute digital input and output signals, and can use io-link protocol sensors, making the electrical layout of the industrial site more flexible, eliminating bulky electrical boxes and cumbersome electrical wiring. According to the use of industrial sites, the amount of electrical wiring is reduced by 87%, and the use of electrical parts is reduced by 74%.

[0051] The io-link master station has a powerful self-checking function. Through the human-machine interface, the operator can monitor the electrical operation status in real time. This includes monitoring the incoming calls and whether the voltage and current of each control port are normal. Such monitoring functions greatly facilitate on-site troubleshooting, because the operator can quickly obtain real-time data of electrical parameters, discover and solve potential problems in time, and reduce downtime caused by electrical failures.

[0052] During the communication process between the master and slave stations, the master station can also display the communication status to ensure the stability and reliability of data transmission. The operator can view the communication status through the human-machine interface to confirm whether the connection between the master and slave stations is normal, which is crucial to ensure the normal operation of the equipment. If a communication problem occurs, it can be quickly located and resolved, thus avoiding production interruptions caused by communication failures.

[0053] The standardization of io-link port wiring makes installation and maintenance easier. Both digital signals and io-link sensors are connected using standard plugs. This standardized design eliminates the need to rely on complex drawings when a line fails. Operators can restore the line based on the status display on the human-machine interface, thereby improving maintenance efficiency.

[0054] The composition of the controlled device is further defined as follows: the controlled device also includes an encoder;

[0055] The human-machine interface is also used to send speed and position information to the PLC;

[0056] The PLC is also used to send the received speed and position information to the encoder, and collect the output data of the encoder in real time, detect whether the encoder is faulty based on the output data, and send the result to the human-computer interaction interface.

[0057] Specifically, encoders are known for their high stability and direct data transmission characteristics. Compared with traditional encoders, PN communication encoders do not need to calculate the position by writing complex pulse programs, but can directly send position data. This direct data transmission method simplifies system design and programming, improves the accuracy and real-time performance of data transmission, and thus reduces problems caused by calculation errors.

[0058] In addition, the PN communication encoder can not only send speed and position signals at the same time, but also provide real-time feedback of its own electrical status through data transmission. These important signals and status information can be viewed through the human-machine interface, allowing the operator to fully understand the working status of the encoder. In this way, the operator can obtain the operating data of the encoder in a timely manner, quickly diagnose and solve potential problems, and further improve the overall reliability and efficiency of the system.

[0059] The composition of the io-link system is further defined as follows: the io-link system includes a master station, digital input and output slave stations, analog input slave stations, and analog output slave stations;

[0060] The PLC is also used to send the received detection data to the digital input and output slave station and the analog input slave station through the master station, and the analog input slave station sends the detection data to the analog output slave station, and collects the output data of the analog output slave station and the digital input and output slave station in real time, detects whether the master station, the digital input and output slave station, the analog input slave station and the analog output slave station are faulty according to the output data, and sends the result to the human-computer interaction interface.

[0061] In addition, io-link sensors can directly send the status values ​​of the sensors to the PLC. This data transmission method eliminates the value conversion procedure of traditional analog sensors and avoids the value error caused by line length. Since io-link sensors send values ​​in the form of data, there is no need for additional shielding protection of the lines, which not only simplifies installation but also greatly reduces cable costs. Overall, the application of io-link technology significantly improves the reliability and economy of the system.

[0062] Further define the composition of the io-link system: the io-link system also includes a valve island;

[0063] The human-machine interface is also used to send switch commands to the valve island;

[0064] The PLC is also used to send the received switch instructions to the valve island and collect the output data of the valve island in real time, detect whether the valve island is faulty based on the output data, and send the result to the human-computer interaction interface.

[0065] The preferred model of PLC is given: the model of PLC is S7-1500 or S7-1200.
