Description

Zero code protocol analysis and full link visual adjustment method for heterogeneous terminal Technical Field The invention relates to the technical field of software development, in particular to a zero code protocol analysis and full link visual debugging method of a heterogeneous terminal. Background Currently, two types of technical paths are mainly developed in the industry when the problem of integration of highly heterogeneous devices is solved. Despite their advances in flexibility in protocol adaptation, from the perspective of the disclosed solution, there are still general drawbacks in the key links that promote integration efficiency and reliability. Scheme one: platform-centric standardization and adaptation drive mode (adaptation of standardized drive) The underlying logic of this scheme is to digest isomerism by establishing a set of "unification criteria" and performing "one-way adaptations" on the device, edge or platform side. 1. Standardized definition the platform side (or industry alliance) predefines communication and data standards. At the data level, this is typically embodied as an "object model" or unified information model, providing a standardized description template for device functions, data points. 2. Unidirectional adaptation path-the device "actively closes" the platform standard by two paths: 1) Path a (device side native adaptation), which is the most ideal path. The device manufacturer develops the product according to the platform standard, and the device firmware native supports standard protocols and object models, and can directly talk with the platform. For example, the device needs to integrate a specific SDK provided by the platform, or design according to standard protocols such as WMMP. 2) Path B (edge side gateway adaptation) this spam scheme is employed when the device uses a proprietary protocol. An edge gateway or a protocol converter is additionally arranged between the equipment and the platform, and the private protocol is translated into a standard format of the platform through secondary development of an adaptation plug-in on the gateway. This essentially sinks the adaptation work from the cloud to the edge side. And (3) analyzing the advantages and disadvantages: The method has the advantages that once the adaptation is completed, the platform side processing is extremely uniform and efficient, and the method is easy to expand and manage and accords with the prospect of large-scale deployment The disadvantage is especially pronounced when dealing with the need for a fast, flexible integration of stock heterogeneous devices: 1. Integration of the storage quantity 'dummy equipment' is difficult, and the scheme is strongly dependent on active transformation of the equipment side or the gateway side. For a large number of deployed, protocol-cured, old industrial devices ("dumb devices"), it is not possible to retrofit the firmware, and the cost of adding dedicated gateways increases, resulting in these devices being excluded from the integration range. 2. The implementation period is long, and the method is a long, professional and uncontrollable process no matter the method pushes equipment manufacturers to produce according to new standards or develop gateway adapter plug-ins for private protocols. The platform user cannot autonomously control the integrated rhythm. 3. Secondary development and debugging thresholds still exist, "secondary development" in the gateway adaptation path, which is essentially still hard-coded or complex script development for a particular protocol. The process of configuring gateway protocol and data mapping is still professional and complicated, and lacks efficient debugging tools, configuration correctness can be verified only by linking with real equipment after deployment, and trial and error cost is high. Scheme II, actively adapting device mode by platform The core idea of the mode is that all isomerism digestion work is borne by the platform side without the need of device side cooperation modification. It is realized mainly by two technical paths, each having characteristics. Path 1 full custom code development-separate communication connections, data parsing and processing procedures are developed de novo for each specific device protocol on the platform side, one-to-one. Path 2, parameterized configuration conversion, the platform provides a general protocol framework and a visual configuration interface. The user generates the adaptation rule by filling in the form (such as selecting the protocol type, setting the port, defining the field structure, offset, data type and other parameters of the data packet), and the general engine built in the platform executes the actual protocol conversion and data processing. This is the main direction of evolution in this mode at present. The scheme has the advantages that: 1. The method has the advantages of zero invasion to equipment and extremely strong compatibility, and is
