[0040] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0041] See Figure 1, an industrial Internet of Things (IIoT) device interface is provided in an embodiment of the present application. The interface includes a board and a card slot. The board is modularly encapsulated based on the device interface. Different device interface types correspond to different types of boards. Each board encapsulates its own identity information, and the board is externally provided with first signal pins; the card slot is fixedly arranged on the outside of the IIoT device for inserting and fixing the board. The card slot is internally provided with second signal pins for corresponding connection with the first signal pins of the board. When the board is inserted, the first signal pins and the second signal pins are correspondingly connected.

[0042] The second signal pins are connected to the main board of the IIoT device through an ID bus.

[0043] In view of the problem that in the prior art, the industrial Internet of Things device interface uses a standardized hardware interface, and the interface type and quantity cannot be changed, resulting in the inability of the hardware ports of the industrial Internet of Things device to flexibly adapt to different application scenarios. In an embodiment of the present application, the device interface adopts a separated form of board and card slot. By inserting different types of boards into the card slots on the industrial Internet of Things device according to the interface requirements in different application scenarios, the interface resource configuration of multiple interface types and different interface type quantities in the application scenario is realized. The applicability of the industrial Internet of Things device interface is improved, the utilization rate of hardware resources is increased, and the cost is reduced.

[0044] Specifically, any board and any card slot can be plugged and unplugged. When the board is inserted into the card slot, its internal circuit is physically connected. That is, when the board is normally inserted into the card slot, the first signal pins of the board and the second signal pins arranged in the card slot are connected to realize the physical connection between the board and the main board.

[0045] Based on the above industrial Internet of Things device interface, a method for multi-scenario adaptation of industrial Internet of Things device interface resources is provided. See Figure 2 , the method includes:

[0046] Step 1, in the current scenario, detect the state of the board inserted into the card slot through the ID bus and obtain the parameter information of the inserted board. The type of the board inserted into the IIoT device and the quantity of different types of boards in the current scenario are determined based on the devices connected to the IIoT device in the current scenario;

[0047] Step 2, obtain the driver program file of the inserted board based on the parameter information of the inserted board and perform driver configuration on the inserted board.

[0048] In the embodiments of the present application, the motherboard of the industrial Internet device detects whether a board is inserted into each card slot through the ID bus. When it is confirmed that a board has been inserted, the parameters of the inserted board are read through the ID bus. Then, the motherboard automatically configures the hardware resources according to the read parameter information of the inserted board and loads the corresponding driver code of the board to implement the function application.

[0049] In one implementation manner, the types of boards include three types: digital output, digital input, and RS485. There are multiple card slots provided on the outside of the industrial Internet device.

[0050] In the embodiments of the present application, multiple card slots can be set on the industrial Internet device according to specific situations to adapt to the situation where the industrial Internet device needs to simultaneously access multiple external devices in the application scenario. It can be understood that there are multiple card slots on the industrial Internet device, and different types of multiple boards can be inserted into the multiple card slots. There can be multiple boards of the same type, realizing the flexible adaptability of the interface resources of the industrial Internet device in different application scenarios. The interface resources include different type configurations of the interfaces and the quantity configuration of the same type of interfaces.

[0051] In one implementation manner, in the above step 1, detecting the state of the board inserted into the card slot through the ID bus and obtaining the parameter information of the inserted board includes: initializing the hardware resource information by starting the Bootloader method, and reading the board chip parameter information on each slot through the ID bus circuit. The board chip parameter information includes the board identity identification information of the board type. Specifically, when the motherboard is powered on, the system starts the BootLoader program, initializes the hardware device, reads the ID bus information, and further reads the board chip parameter information on each slot through the ID bus circuit;

[0052] In the above step 2, obtaining the driver program file of the inserted board based on the parameter information of the inserted board and performing driver configuration on the inserted board includes:

[0053] Step 21: Search for and load the driver file that matches the board in the preset internal driver module based on the read board chip parameter information.

[0054] Further, referring to Figure 3 , in the above step 21, searching for and loading the driver file that matches the board in the preset internal driver module based on the read board chip parameter information includes:

[0055] Step 211: Write the read board chip parameter information into the startup parameter Param;

[0056] Step 212: Invoke the Kernel method to read the board chip parameter information in each card slot from Param, and search and match the read board chip parameter information in the preset internal driver module to obtain the driver program file corresponding to the interface type represented by the board chip parameter information;

[0057] Step 213: Load the driver program file and wait for the application program to use it.

[0058] In the embodiment of the present application, when the main board is powered on, the system BootLoader program starts. The main board reads the stored data of the board chips on each slot through the ID bus circuit, writes the board type information collected on each slot into Param, and invokes the Kernel program to start. After the Kernel program starts, it first reads the board chip parameter information in each card slot from Param and matches it with the internal driver module. When the corresponding driver is matched, the corresponding driver is mounted and waiting for the application code to use.

[0059] It can be understood that considering that there may be multiple different types of boards inserted in the multiple card slots of the industrial Internet device interface in the embodiment of the present application, and there may be multiple boards of the same type. After reading the board chip parameter information of the board chips on each slot through the ID bus circuit, it further includes: determining whether the driver program file of the board type has been loaded based on the read board type. If it is determined that it has been loaded, then no longer search and match the driver file of the board in the preset internal driver module based on the read board chip parameter information and load the driver file. To avoid loading the driver program files of multiple boards of the same type multiple times. It can be understood that after the industrial Internet device main board finishes loading the driver program file of the board type in the card slot, it records and stores data such as the card slot position (card slot identification number), the board chip parameter information in the card slot, the driver program file data, and the driver loading status of the industrial Internet device, and determines whether the driver program file of the board type has been loaded based on the read board type, which can be determined by searching and finding in the recorded data.

[0060] It can be understood that when searching and matching the read board chip parameter information in the preset internal driver module, if the driver program file corresponding to the board is not searched and matched, an alarm log message is printed and waiting for the technical personnel to perform fault troubleshooting.

[0061] In one implementation, the above method for multi-scenario adaptation of industrial Internet device interface resources further includes the following steps:

[0062] For the card slots with boards inserted, detect the connection status of the first signal pin of the inserted board and the second signal pin set in the card slot;

[0063] When the connection status is normal, control the connection indicator light of the card slot to turn on. When the connection status is abnormal, control the connection indicator light to turn off.

[0064] Specifically, in the embodiment of the present application, the connection status of the first signal pin of the board card in the card slot and the second signal pin set in the card slot is detected. In addition, an interface indicator light is set outside each card slot of the industrial Internet device. For the card slot into which the board card has been inserted, the detection result of the connection status of the first signal pin and the second signal pin inside it can be intuitively displayed to the user through the interface indicator light. When the board card in the card slot is normally connected, the corresponding indicator light turns on. When there is a connection fault, the indicator light turns off. This is convenient for the user to confirm the connection status of the board card and facilitates troubleshooting when the device fails. In one implementation manner, when the board card is inserted into the card slot, the insertion state will be detected and obtained, that is, it is determined that there is a board card in the card slot. Further, the main board of the industrial Internet device detects whether a board card is inserted into each card slot through the ID bus. If it is confirmed that a board card has been inserted into the card slot, it means that the connection status of the first signal pin and the second signal pin of the board card in the card slot is normal, and the interface indicator light corresponding to the card slot turns on. At the same time, the main board of the industrial Internet device can read the parameters of the inserted board card through the ID bus. Otherwise, if the main board of the industrial Internet device does not detect that a board card has been inserted into the card slot through the ID bus, it means that the connection status of the first signal pin and the second signal pin of the board card in the card slot is abnormal, and the interface indicator light corresponding to the card slot turns off.

[0065] In one implementation manner, in step 213 above, loading the driver program file and waiting for the application program to use includes:

[0066] Use the Kernel method to load the driver program file and store the loading status;

[0067] Start the application program, obtain the board card information and board card loading status of each card slot on the industrial Internet device and display them to the user.

[0068] Specifically, after the kernel code starts up, it jumps to the file system program to start each application program. The industrial Internet device in the embodiment of the present application adopts a dual-system mode to avoid irreversible errors in the system caused by faults during later system upgrades. After the application program starts, the board card information of each slot is displayed on the user interface for the user to view.

[0069] Specifically, the partition structure of the operating system in the industrial Internet device in the embodiment of the present application is as Figure 4 shown, where:

[0070] Bootloader: The system bootloader is used for hardware device initialization and reading ID bus information.

[0071] Param: The system startup parameters are used to store settable parameters, and the parameters are passed to the kernel.

[0072] Kernel: The system driver is used to start and load the loaders for various device drivers.

[0073] CFG: The device configuration parameters are used to store the application configuration parameters of the device.

[0074] Filesystem A: File system A, the application programs running on the system.

[0075] Filesystem B: File system B, the application programs running on the system.

[0076] Based on Figure 1 The industrial Internet device interface shown, the embodiment of the present application also provides a multi-scenario adaptation system for industrial Internet device interface resources. The industrial Internet device interface includes a board and a card slot. The types of the board include three categories: digital output, digital input, and RS485. There are multiple card slots arranged on the outside of the industrial Internet device;

[0077] The system includes:

[0078] The inserted board parameter acquisition unit is used to detect the state of the inserted board in the card slot and obtain the parameter information of the inserted board through the ID bus in the current scenario. The type of the inserted board and the number of different types of boards in the industrial Internet device in the current scenario are determined based on the devices connected to the industrial Internet device in the current scenario;

[0079] The inserted board parameter parsing unit is used to obtain the driver program file of the inserted board based on the parameter information of the inserted board and perform driver configuration on the inserted board.

[0080] In one implementation, the above inserted board parameter parsing unit includes:

[0081] The board parameter writing unit is used to write the read board chip parameter information into the startup parameter Param;

[0082] The board driver search unit is used to call the Kernel method to read the board chip parameter information in each card slot from Param, and search and match the read board chip parameter information in the preset internal driver module to obtain the driver program file corresponding to the interface type characterized by the board chip parameter information;

[0083] The board driver loading unit is used to load the driver program file and wait for the application program to use.

[0084] For the specific limitations of the multi-scenario adaptation system for industrial Internet of Things device interface resources, reference can be made to the limitations of the multi-scenario adaptation method for industrial Internet of Things device interface resources in the foregoing text, which will not be elaborated herein. Each of the above units can be stored in the memory of a computer device in software form, so as to facilitate the processor to call and execute the operations corresponding to each of the above units.

[0085] An embodiment of the present application further provides a computer-readable storage medium storing executable instructions, which, when executed by a processor, implement the above multi-scenario adaptation method for industrial Internet of Things device interface resources. The storage medium may be a read-only memory (ROM), a random access memory (RAM), a compact disc read-only memory (CD-ROM), magnetic tape, floppy disk, optical data storage node, etc.
