Method for making Internet-of-Things cloud gateway compatible with multiple protocols and Internet-of-Things cloud gateway

Abstract

The invention relates to the communication field and discloses a method for making an Internet-of-Things cloud gateway compatible with multiple protocols and the Internet-of-Things cloud gateway. In the invention, the gateway sends a request identifying command to a USB adapter inserted into a USB interface via a communication protocol; if the gateway receives responses of the USB adapter to the request identifying command, the communication protocol supported by the USB adapter can be directly obtained; the communication protocol supported by the USB adapter is a communication protocol corresponding to the request identifying command; if the gateway does not receive the responses, the gateway sends the request identifying command to the USB adapter via another communication protocol till the gateways receives the responses, and therefore the communication protocol supported by the USB adapter can be obtained. In an embodiment of the method for making the Internet-of-Things cloud gateway compatible with multiple protocols and the Internet-of-Things cloud gateway, without replacement of the gateway or arrangement of other wireless communication chips, the gateway can be compatible with multiple communication protocols via the USB interface, a problem that a new gateway is needed for supporting a new communication protocol can be prevented, cost can be saved, and a gateway utilization rate is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a multi-protocol compatible method of an Internet of Things cloud gateway and an Internet of Things cloud gateway. Background technique [0002] The Internet of Things is an important part of the new generation of information technology, and its English name is: "The Internet of Things". As the name suggests, the Internet of Things is the Internet of things connected. The Internet of Things mainly adopts wireless communication technology. General IoT short-range wireless communication methods include Zigbee, Bluetooth Low Energy BLE (BluetoothLowEnergy), 433MHz, WI-FI, Z-wave and 6LoWPAN, etc. The existing short-range wireless communication of the Internet of Things sometimes requires multiple protocols to run in parallel at the same time, resulting in incompatibility with each other. [0003] like figure 1 As shown, the existing IoT cloud gateway includes a wireless communication c...

Problems solved by technology

In this case, in order for the IoT cloud gateway to support multiple short-distance communication protocols at the same time, it is only possible to add a variety of wireless communication chips to the original gateway, such as adding Bluetooth (BLE) wireless chips to the 433MHz gateway. After the communication chip and Zigbee wireless communication chip, the 433MHz gateway can support 433MHz, Bluetooth ...
