How to adopt an efficient way, establish as many device access points as possible with as good compatibility, becomes the focus of efforts for the parties.
The popularization of the internet of things technology generally faces a very short technical pattern. Decentralization is the main trend in the current development of IT technology. Under the diversity access pattern, formats of different kinds and different protocol specifications are diversified. In consideration of cost, the performance of a general gateway is weak, and a traditional access mode of an internet of things gateway adopts a mode of directly performing directional docking aiming at a protocol, which requires that the gateway must complete protocol support for a device when issuing, so that the device must perform docking by a specific gateway.

In patent No. CN200710031116.1 entitled "a method for designing a universal gateway based on object model and protocol configuration", an automatically generated upgrade program is used instead of a rule type, and the object gateway needs a dedicated gateway, which limits the use of the gateway for large-scale universal gateways. In order to enhance the cross-platform universality, the wide compatibility of the protocol and the flexibility of the sustainable upgrading of the protocol of the gateway accessed by the equipment, some edge system manufacturers, such as Baidu and Ali, try to adopt development languages such as JavaScript or Lua and the like as carriers in the field of universal access gateway products, and enable the gateway to have the equipment access support capability of upgrading after release in a remote push mode.
