Embodiment Construction

[0034] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0035] One embodiment of the present invention is a JavaScript-based Internet of Things device data format conversion system, the system includes a core service module, a simulation service module, a script engine module, a converter module and a sandbox module, and the relationship between each module is as follows figure 1 As shown, the following JS scripts are JavaScript scripts. combine figure 2 shown, where:

[0036] The simulation service module is used to receive the JS script of the client, and check and judge the current JS script. If the judgment result is yes, the core service module will be called to store the current JS script as a draft, otherwise, it will be returned to the client Prompt; and, the simulation service module is also used to receive simulation data after the current JS script is stored as a draft, and transmit the current JS script and ...

Abstract

The invention discloses an Internet of Things equipment data format conversion system based on JavaScript, and belongs to an Internet of Things equipment data format conversion method. The method comprises the steps that a user compiles a JS script and analog data for one kind of equipment through a browser, and after the JS script passes execution of the analog data in a sandbox through a JS engine, a core service is called for persistent storage; the JS scripts which do not pass the execution can only be stored as draft states; a converter loads the JS script (formal) and an equipment identifier; and the equipment side accesses the system through the protocol gateway, and the protocol gateway performs data conversion through the converter to complete interaction.

Description

technical field [0001] The present invention relates to a data format conversion method of an Internet of Things device, and more specifically, the present invention mainly relates to a JavaScript-based Internet of Things device data format conversion system. Background technique [0002] With the rise of IoT applications, various sensing devices emerge in an endless stream. Due to different usage scenarios, access networks and protocols are also different, such as NB-IoT, LoRa, Wi-Fi, and 4G are the most commonly used. Commonly used IoT application layer protocols include MQTT, HTTP, XMPP, CoAP, etc., among which MQTT application is more common. Taking the MQTT protocol as an example, different devices have different data formats, such as JSON and binary. The current practice is hard-coded conversion, and a set of code logic is written to process different device data formats; in the requirements stage, at least the type of device and related protocols and data formats mu...
