[0020] The present invention will be further described with reference to the accompanying drawings, but the content of the drawings does not constitute any limitation on the present invention.

[0021] Figure 1 This is a schematic diagram of the system layout of this utility model. Detailed Implementation

[0022] To make the purpose, technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and examples.

[0023] Example 1

[0024] like Figure 1 The system shown is configured with a PLC central processing unit with an Ethernet port and two IO-Link master stations, each of which is extended with an IO-Link digital slave station, based on the characteristics of the internal mixer.

[0025] The first IO-Link master station 6 is responsible for connecting the feed section of the internal mixer and the sensors on the left side of the mixer body. These digital sensors are concentrated at the feed section. An IO-Link digital slave station 8 is installed at the feed section, connected via a third cable 7 with an M12 round connector. The digital slave station and the sensors are connected via dedicated sensor cables. These digital sensors include: a feed top position sensor, a feed rise position sensor, a feed cleaning position sensor, a feed slow-descent position sensor, a feed door open position sensor, a feed door closed position sensor, and an emergency stop button—a total of seven digital signals. Once all sensors and the digital slave station 8 are connected and fixed, the equipment does not need to be altered during transportation and installation. Only the feed displacement sensor and the connecting cable 7 between the IO-Link digital slave station 8 and the first IO-Link master station 6 need to be removed during separate transportation and installation. The first IO-Link master station 6 is installed on the left side of the machine body, connecting the four temperature sensors and pressure displacement sensors on the left side of the machine body, as well as the IO-Link digital slave station 8. The first IO-Link master station 6 exchanges data with the switch 4 through the first connecting cable 5.

[0026] The second IO-Link master station 12 is responsible for connecting the internal mixer's discharge door locking mechanism and the sensors on the right side of the internal mixer body. These digital sensors are concentrated at the discharge door locking position. A second IO-Link digital slave station 14 is installed at the discharge door locking mechanism, connected via a dedicated cable 13 with an M12 round connector. The digital slave station and the sensors are connected via dedicated sensor cables. These digital sensors include: a discharge door half-open sensor, a discharge door open sensor, a discharge door half-closed sensor, a discharge door closed sensor, a locked position sensor, a released position sensor, and an emergency stop button—a total of seven digital signals. The second IO-Link master station 12 is installed on the right side of the machine body, connecting the four temperature sensors on the right side of the machine body, the discharge door temperature sensor, and the second IO-Link digital slave station 14. The second IO-Link master station 12 exchanges data with the switch 4 via a second connecting cable 11.

[0027] PLC2 is connected to switch 4 via network cable 3, exchanging data with IO-Link master station 6 (#1) and IO-Link master station 12 (#2). The hardware configuration is fixed, and the system has reserved backup points for future expansion and upgrades. Different communication systems are configured within the PLC, with different communication programs corresponding to different data blocks. Each data block is mapped to a fixed external physical address of the PLC, with the same physical address mapping to different data blocks. The system calls different communication systems within the PLC based on the different positions of the key knob 9, sending different data blocks to the upper-level system without requiring different configurations based on the brand of the upper-level system, saving time and simplifying the process. When the key knob is in the S7 position, the system calls the communication system associated with Siemens; in the MC position, the system calls the communication system associated with Mitsubishi; and in the E / IP position, the system calls the communication system associated with Rockwell. These three different PLC brands can cover more than 90% of the internal mixer control systems on the market. The address and related communication status of the data block are displayed on the human-machine interface 1 for easy monitoring by the user. The human-machine interface is connected to the switch 4 via network cable 10.
