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 the data transmission between heterogeneous devices is realized through the server, it is necessary to manage and maintain the server, which makes it more difficult to manage and maintain the server. high cost
In addition, since the data needs to be forwarded by the server, the delay in transmitting data is high, resulting in poor real-time performance of data transmission

Embodiment Construction

[0034] 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.

[0035] Many network application requirements in the information age have given birth to a variety of wireless network communication protocols. The Internet of Things incorporates many wireless network protocols into a common network framework, bringing about the vigorous development of wireless sensing and control applications. The three wireless networking standards in common use today are wifi, ZigBee, and Bluetooth. Among them, WiFi has technical advantages such as wide coverage of radio waves and fast transmission speed. For example, users are allowed to access the network at any time and any place within the network coverage, enjoy a series of broadband information v...

Abstract

The invention provides a data transmission method, a receiving end and a transmitting end, and belongs to the technical field of communication. The method comprises the steps: detecting corresponding energy intensity indication for any sampling point in any time window when the transmitting end transmits the data package; determining an energy threshold section where the energy intensity indication is located, and enabling a value corresponding to the energy threshold section to serve as a decoding value of any sampling point; and determining the decoding value of any time window according to the decoding value of each sampling point in any time window. According to the invention, the energy threshold section where the detected energy intensity indication is located is determined, and the value corresponding to the energy threshold section serves as the decoding value of any sampling point, thereby determining the decoding value of any time window. Because a third side does not need to carry out the data forwarding for data transmission, the cost of data transmission is saved. In addition, because data is transmitted to the receiving end from the transmitting end in a form of energy, there is no time delay caused by forwarding, thereby enabling the instantaneity of data transmission to be better.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a data transmission method, a receiving end and a sending end. 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 data transmission problem between heterogeneous devices, the existing data transmission method mainly sends the data to the server by the sending end, and transmits the data to the receiving end through the protocol conversion of the server, so that the receiving end receives the data sent by the server Complete data transfer. [0003] In the process of realizing the present invention, it is found that the ...
