Problems solved by technology

[0003] In the process of realizing the present invention, it is found that the prior art has at least the following problems: when realizing cross-protocol communication between heterogeneous devices through wireless gateways, a large number of wireless gateway devices need to be pre-deployed, which requires higher hardware costs and maintainance fee
In addition, since the data needs to be forwarded through the wireless gateway, the delay in transmitting data is high, resulting in poor real-time performance of data transmission

Embodiment Construction

[0029] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] The three wireless networking technologies in common use today are WiFi, ZigBee, and Bluetooth. The above three different wireless technologies are suitable for different application scenarios. How to maximize the strengths and avoid weaknesses of the data transmission of various wireless technologies, so as to realize the interconnection of all things in the entire Internet of Things world is a big challenge. On the one hand, the working frequency bands of WiFi, ZigBee and Bluetooth are all 2.4GHz free ISM (Industrial Scientific Medical) frequency bands. In many scenarios, the coexistence of these heterogeneous devices in physical space will inevitably lead to thei...

Abstract

The invention provides a cross-protocol communication method and device, and belongs to the field of communication technology. The method comprises that the signal to noise ratio of any a time window is calculated according to a sampling result of a last time window; according to the signal to noise ratio, the energy level and the length of the time window are adjusted; on the basis of the adjusted energy level and time window length, energy intensity indication corresponding to a sending end when sending a data packet is detected; and according to the energy intensity indication, a decoding value of the time window is determined. According to the invention, the decoding value of any time window can be determined according to the energy level indication. It is not required to forward data by a third party, time delay caused by forwarding is avoided, the transmission cost is reduced, and the instantaneity of data transmission is higher. In addition, the energy level and time window length are adjusted in real time according to the signal to noise ratio, the data transmission rate is optimized on the premise that the error rate is lower, and the effective throughput of a communication system is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a cross-protocol communication method and device. Background technique [0002] With the vigorous development of the Internet of Things, various wireless devices appear in large numbers. Since the wireless network protocols used by the wireless devices are usually different, there will be serious spectrum competition and interference problems between the wireless devices coexisting in the 2.4GHz free frequency band. In order to realize the problem of data transmission between heterogeneous devices, the existing data transmission method mainly sends the data to the wireless gateway by the sending end. Based on the routing function of the wireless gateway, the protocol conversion is performed on the data through the wireless gateway, and the data after the protocol conversion is forwarded to the receiving end. The receiving end completes the cross-protocol ...
