[0016] The main PLC calculates the fluctuation value of the difference in the log. If the fluctuation value exceeds the set threshold, the PROFINET communication link is determined to be abnormal.

[0044] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0046] The crusher communication networking method based on PROFINET provided in this embodiment of the invention is executed by a computer device, and correspondingly, the crusher communication networking system based on PROFINET runs in the computer device.

[0047] Figure 1 This is a schematic flowchart illustrating a method according to an embodiment of the present invention. Wherein, Figure 1 The executing entity can be a PROFINET-based crusher communication network system. Depending on different requirements, the order of the steps in this flowchart can be changed, and some can be omitted.

[0048] like Figure 1 As shown, the method includes:

[0049] Step 110: Establish a PROFINET communication link between the main PLC and the crusher;

[0050] Step 120: Connect a TCP communication link between the main PLC and the host computer, wherein the host computer and the crusher are connected by a cable;

[0051] Step 130: The main PLC monitors the communication status of the PROFINET communication link. If the communication status of the PROFINET communication link is abnormal, it sends a command to the host computer to obtain information about the crusher.

[0052] To facilitate understanding of the present invention, the following description further illustrates the crusher communication networking method based on PROFINET provided by the present invention, using the principle of the crusher communication networking method based on PROFINET and the communication construction process in the embodiments.

[0053] For details, please refer to Figure 2 The PROFINET-based crusher communication networking method includes:

[0054] S1. Establish a communication link.

[0055] Establish a PROFINET communication link between the main PLC and the crusher; connect a TCP communication link between the main PLC and the host computer, wherein the host computer and the crusher are connected by a cable.

[0056] The main PLC's first network port establishes a communication connection with the crusher through the first network segment. The main PLC's second network port connects to the host computer through the second network segment.

[0057] Communication between SMART200 and Siemens 1500 via PROFINET eliminates the need for CPU resources, allowing for direct input / output mapping and communication. Furthermore, the added SMART200 system is placed on a separate network segment, isolated from the original 1500 system's slave stations, ensuring system security, reducing CPU load, and avoiding potential risks associated with the modification.

[0058] Specifically, the SMART200 and main PLC1500 systems of the two devices are controlled via Ethernet. Only two network cables need to be laid from the control cabinets of the two crushers to the main PLC1500 in the PLC room. The configuration and programming of the program can be carried out on the host computer. This solution can avoid the risk of damage to the main PLC module caused by the introduction of high voltage through hard wiring. The construction is simple and quick, requires less material, and has low cost.

[0059] S2, Communication Management.

[0060] The main PLC monitors the communication status of the PROFINET communication link. If the communication status of the PROFINET communication link is abnormal, it sends a command to the host computer to obtain information about the crusher.

[0061] The main PLC periodically sends clock query requests to the crusher via the PROFINET communication link to obtain the crusher's system time. The main PLC calculates the difference between its local system time and the obtained crusher system time and saves the difference to a log. The main PLC calculates the fluctuation value of the difference in the log; if the fluctuation value exceeds a set threshold, the PROFINET communication link is deemed abnormal. The main PLC sends authentication information to the host computer to grant the host computer control over the crusher. The main PLC sends a target data item to the host computer, which obtains the parameter value of the target data item from the crusher and feeds the parameter value back to the main PLC.

[0062] Specifically, the average of multiple differences in the log is calculated, the difference between the latest generated difference and the average is calculated, and the percentage of this difference to the average is calculated to obtain the fluctuation value. If the fluctuation value exceeds 20%, the communication link is considered abnormal, indicating a high risk. Redundant links are then enabled, and the main PLC authorizes the host computer to gain control over the crusher. The main PLC then uses the host computer to acquire data from the crusher and issue control commands.

[0063] In some embodiments, the PROFINET-based crusher communication network system may include multiple functional modules composed of computer program segments. The computer programs for each program segment in the PROFINET-based crusher communication network system may be stored in the memory of a computer device and executed by at least one processor to perform (see details). Figure 1 (Description) Functionality of crusher communication networking based on PROFINET.

[0064] In this embodiment, the PROFINET-based crusher communication networking system can be divided into multiple functional modules according to the functions it performs. A module, as referred to in this invention, is a series of computer program segments that can be executed by at least one processor and perform a fixed function, stored in memory. In this embodiment, the functions of each module will be detailed in subsequent embodiments.

[0065] The first communication module is used to establish a PROFINET communication link between the main PLC and the crusher;

[0066] The second communication module is used to connect a TCP communication link between the main PLC and the host computer, wherein the host computer and the crusher are connected by a cable.

[0067] The communication management module is used by the main PLC to monitor the communication status of the PROFINET communication link. If the communication status of the PROFINET communication link is abnormal, it sends an instruction to the host computer to obtain crusher information.

[0068] Optionally, as an embodiment of the present invention, the first communication module includes:

[0069] The main PLC's first network port establishes a communication connection with the crusher through the first network segment.

[0070] Optionally, as an embodiment of the present invention, the second communication module includes:

[0071] The main PLC's second network port is connected to the host computer via the second network segment.

[0072] Optionally, as an embodiment of the present invention, the communication management module includes:

[0073] The main PLC periodically sends a clock query request to the crusher via the PROFINET communication link to obtain the system time of the crusher.

[0074] The main PLC calculates the difference between the local system time and the acquired system time of the crusher, and saves the difference to the log.

[0075] The main PLC calculates the fluctuation value of the difference in the log. If the fluctuation value exceeds the set threshold, the PROFINET communication link is determined to be abnormal.

[0076] The main PLC sends identity authorization information to the host computer so that the host computer can obtain the authority to control the crusher;

[0077] The main PLC sends the target data item to the host computer, and the host computer obtains the parameter value of the target data item from the crusher and feeds back the parameter value to the main PLC.
