The internet of things refers to connecting any object with a network through information sensing equipment according to a stipulated protocol, and carrying out information exchange and communication on the object through an information transmission medium so as to realize the functions of intelligent identification, positioning, tracking, supervision and the like. Along with the development of the internet of things technology, more and more terminal devices are accessed into an internet of things platform, in the prior art, development and test of the internet of things platform terminal access are required to depend on real devices for development, debugging and test, as the devices have more access protocols, HTTP, TCP, MQTT, LWM2M, JT/T808, tlink, modbus and the like are involved, and the devices with the same protocol are also different in encryption mode and data format, so that all real devices cannot be integrated.
Based on the above, the simulation platform based on the Internet of things management system provided by the embodiment of the invention can simulate real equipment to perform operations such as equipment login, data reporting, event reporting, instruction issuing response and the like, and can realize the life cycle function development test of the Internet of things management system equipment without the real equipment, thereby improving the research and development speed and the test efficiency.
Referring to fig. 1, an embodiment of the invention provides a simulation platform based on an internet of things management system, which comprises a terminal simulation system and an internet of things platform automation system. In this embodiment, the terminal simulation system may be built by java. Specifically, java is a portal object-oriented programming language. The java language has the characteristics of strong functions, simplicity, easiness in use, simplicity, object-oriented property, distributed property and the like, and can write desktop application programs, web application programs, distributed systems, embedded system application programs and the like. The internet of things platform automation system can be built by python+rf+selenium. Specifically, python is a widely used interpreted, high-level and general-purpose programming language. Python provides an efficient, high-level data structure that can also be easily and efficiently programmed towards objects. Python grammar and dynamic type, as well as the nature of interpreted languages, make it a programming language for writing scripts and rapidly developing applications on most platforms. Selenium is a pool of Python. RF (Robot Framework) is open source software which is based on Python language to write an automatic test framework, can write test cases, has good expandability, belongs to keyword driving and also has data driving.
In this embodiment, the terminal simulation system includes a protocol forwarding module and a terminal simulation module, and the terminal simulation module includes several types of terminal simulators. The protocol forwarding module is used for determining a target protocol according to the message template issuing instruction and forwarding the target protocol to the corresponding terminal simulator so that the terminal simulator simulates the operation of real equipment according to the content of the target protocol. The system comprises an Internet of things platform automation system and a terminal simulator, wherein the Internet of things platform automation system comprises a southward module and a northbound module, the southward module is used for sending a constructed message template issuing instruction to the protocol forwarding module and receiving simulation state data of the terminal simulator; the north direction module is connected with the Internet of things management system and is used for forwarding the simulation state data sent by the south direction module to the Internet of things management system or the Internet of things management platform. Specifically, the real device operation includes operation processes such as device login, event reporting, data reporting or instruction issuing response.
In this embodiment, the terminal simulator includes HTTP, TCP, MQTT, LWM2M, JT/T808, tlink, modbus. In particular, HTTP (HyperText Transfer Protocol ) is an application layer protocol for distributed, collaborative and hypermedia information systems, which is the basis for data communication over the world wide web and is also the most widely used network transfer protocol for the internet. HTTP was originally designed to provide a method of publishing and receiving HTML pages. TCP (Transmission Control Protocol ) is a connection-oriented, reliable, byte-stream-based transport layer communication protocol, defined by IETF RFC 793. In the simplified OSI model of computer networks, TCP performs the functions specified by the fourth transport layer, and User Datagram Protocol (UDP) is another important transport protocol within the same layer. In the internet protocol suite (Internet protocol suite), the TCP layer is an intermediate layer that sits above the IP layer and below the application layer. MQTT (Message Queuing Telemetry Transport, message queue telemetry transport) is an instant messaging protocol developed by IBM and is likely to be an important component of the internet of things. The MQTT holds all platforms, can connect almost all networking items and the outside, and is used as a communication protocol for sensors and actuators. LWM2M (light M2M, lightweight M2M) is a Lightweight, standard and general device management protocol for the internet of things, and can be used for rapidly deploying the internet of things service in a client/server mode. Modbus is a bus protocol of an industrial communication system. The proposal is a common language applied to electronic controllers. Through the Modbus protocol, controllers may communicate with each other, with controllers via a network (e.g., ethernet) and other devices. It has become a common industry standard. With Modbus protocol, control devices produced by different manufacturers can be connected into an industrial network to perform centralized monitoring. Modbus defines a message structure that a controller can recognize for use, regardless of the network over which they communicate. When communicating over a Modbus network, the Modbus protocol determines what actions each controller needs to know their device address, identify messages sent by address, and determine what actions to take. If a response is required, the controller will generate feedback information and issue using the Modbus protocol. On other networks, messages containing the Modbus protocol are converted into a frame or packet structure for use on the network. This translation also extends the methods of resolving node addresses, routing paths, and error detection according to the particular network.

The product device parameters include a product master key, a device ID, or a device key. Meanwhile, a message template is constructed, and then an instruction corresponding to the product equipment parameter is sent to a protocol forwarding module of the terminal simulation system through the message template.
Step S230, the terminal simulation system receives a device login instruction and simulates a device login operation according to the device login instruction;
in the embodiment of the application, after the terminal simulation system receives the equipment login instruction, the protocol type is judged through the protocol forwarding module, and the protocol of the corresponding protocol type is forwarded to the corresponding terminal simulator, so that the terminal simulator can simulate the real operation process of the equipment. Specifically, after receiving the equipment login information, the terminal simulator verifies whether the product master key, the equipment ID and the equipment key exist, if so, the terminal simulator executes the simulated equipment login operation, and returns a simulation result to the Internet of things management system, so that a tester can conveniently know simulation test data.
