Multi-protocol fusion gateway of Internet of Things

Abstract

The invention discloses a multi-protocol fusion gateway of the Internet of Things. The multi-protocol fusion gateway comprises an EFR32 chip for supporting dual-mode application. The mt7688a main board realizes the function of a router. The 485 wire provides access of a 485 wire protocol. 433mhz is used for providing access of 433mHz equipment. The USB provides a wide range of equipment access interfaces. The loudspeaker provides a voice output function. The indicator lamp provides GPIO LED lamp output, indicates the working states of a power supply, a TCP network and a Zigbee / Bluetooth network and a 12V / 1A power supply, and is electrically connected with all the components, so that the overall design of multiple hardware interfaces is realized, and the protocol docking time and the schemeverification time of a client can be reduced. Linkage and automation of multiple types of protocols can be realized. A user can freely configure and is not limited by equipment difference. The overall design reduces the cost of a final product, achieves the coexistence of Bluetooth and ZigBee, and does not need to access two modules at the same time.

Description

technical field [0001] The invention relates to the technical field of Internet of Things docking protocols, in particular to an Internet of Things multi-protocol fusion gateway. Background technique [0002] The current general technical status: Internet of Things applications using Wifi, Bluetooth, Zigbee and wired 485, network cables, etc. are common. For a single environment application, each solution provider has its own characteristics, but it is relatively limited that it can only be applied in a certain environment. Problems existing in the current application in an environment or working in a certain way: [0003] 1. For the Wifi solution, there will be a problem of too few networked devices, and a general home router can only carry about 10-15 devices; [0004] 2. Bluetooth has problems such as incomplete types of devices and too few connected devices; various low-power sensors do not support Bluetooth solutions; [0005] 3. Zigbee will have some equipment types ...

AI Technical Summary

Problems solved by technology

[0003] 1. For the Wifi solution, there will be a problem of too few networked devices, and a general home router can only carry about 10-15 devices;

[0004] 2. Bluetooth has problems such as incomplete types of devices and too few connected devices; various low-power sensors do not support Bluetooth solutions;

[0005] 3. Zigbee will have some equipment types that cannot meet user needs, such as central air conditioners, etc.;

[0006] 4. The wired solution is difficult to adapt to the intelligent transformation of old houses

Rewiring is required, etc.;

[0007] 5. At the same time, a single system solution, once an error occurs in a certain part of the program, it will lead to the collapse of the entire home system;

[0008] 6. The networking method is single and does not support configurable

[0009] 7. The overall number of networking is too small to meet the large-scale networking applications of large office environments and villas.

Lack of configurable automation scenarios
