Description

Technical Field

[0001] The present invention relates to the technical field of experimental teaching, and in particular to an industrial Internet of Things teaching and training platform. Background Art

[0002] In modern industrial Internet of Things systems, the transmission of control information, the collection of on-site environmental parameters, and the monitoring of equipment operating conditions often require the use of different interfaces and protocols for implementation. The working characteristics of related interfaces and the semantic elements of commonly used industrial control protocols are not only relatively abstract, but also have very complex internal logical relationships. Teaching practice shows that relying only on some industrial Internet of Things teaching experiment modules, using related debugging software to display and analyze the effects, and then guiding students to experiment and practice, can never explain to students clearly and thoroughly their internal connections and working mechanisms.

[0003] Due to the lack of experience of the overall correlation effect, students' understanding and mastery of these knowledge only remain at the level of "roughly understanding the function" and "understanding but not knowing where to use it". In order to effectively solve the above problems existing in both teaching and learning, the present invention provides an industrial Internet of Things teaching and training platform. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the shortcomings of the prior art, the present invention provides an industrial Internet of Things teaching and training platform, which is an industrial Internet of Things comprehensive experimental training platform with multiple interfaces that can be flexibly switched, visual settings of industrial control protocols, and visual display of industrial control effects and on-site data. It provides support for teachers to analyze the semantics of industrial control protocols, display and parse the effects of industrial control algorithms, and for students to practice industrial control equipment wiring, programming to achieve industrial control data collection, equipment control, and control effect analysis.

[0006] (II) Technical solution

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] The industrial Internet of Things teaching and training platform includes an application layer and an industrial controller. The industrial controller is connected to an industrial monitoring screen, a ZIGBEE module, a multi-channel IO expander, and an NB-IOT module. The ZIGBEE module is connected to the multi-channel IO expander and is connected to an execution element group and a sensor group. The industrial controller communicates with the industrial monitoring screen, the ZIGBEE module, the multi-channel IO expander, and the NB-IOT module through a 485 interface, a network interface, and a TTL serial port. The industrial controller is connected to a drive module. The industrial controller is connected to a data acquisition module. The data acquisition module collects information based on sensors of modbus-rtu and modbus-tcp industrial control protocols.

[0009] Furthermore, the application layer is connected to the system layer, the system layer includes a driver manager, and the driver manager is connected to the driver layer nodes and the interface driver set.

[0010] On the basis of the above scheme, the system layer is connected to the system hardware device layer, and the system hardware device layer includes a 485 interface, a CAN interface, a digital interface, an analog interface, a UART interface and an IIC interface.

[0011] As a further solution of the present invention, the application layer provides an industrial Internet of Things teaching platform software system interface to users, and by calling the application layer function function provided by the interface, applies to the platform system layer for creating a hardware interface driver as shown in the hardware device layer. The system layer creates an interface driver according to the interface type, and creates a virtual device driver for the device physically connected to the corresponding interface according to the device ID provided when calling the application layer function function.

[0012] Furthermore, the driver module includes a target device driver, a forwarding device driver, and a device driver that actively generates message elements.

[0013] On the basis of the above solution, the driving module reads the message by actively reading the message element during driving.

[0014] As a further solution of the present invention, the data acquisition module includes a data manager and at least one data collector.

[0015] The beneficial effects of the present invention are:

[0016] 1. The industrial controller of the present invention communicates with the industrial monitoring screen, ZIGBEE module, multi-channel IO expander, and NB-IOT module through the 485 interface, network interface, and TTL serial port to realize the operation and status monitoring of the field equipment.

[0017] 2. The system layer of the present invention creates an interface driver according to the interface type, and creates a virtual device driver for the device physically connected to the corresponding interface according to the device ID provided when calling the application layer function. This approach provides great flexibility and convenience for the teaching platform to expand the interface and the devices required to be connected to the interface according to actual needs.
