Problems solved by technology
[0004] However, both query and fixed-path communication methods have certain defects.
For the query communication method, since the gateway must perform polling operations at all times, and the polling operation consumes resources and time, the query communication method has certain requirements for the number of wireless devices in the wireless communication system. If this number is exceeded, the data transmission efficiency in the wireless communication system will slow down, thus resulting in limited application range of the wireless communication system
For the fixed-path communication method, since the communication link of each wireless device needs to be configured, it will take a lot of time to build a network, and when the wireless device in the communication link fails, it may cause the entire network to fail. If one communication link is broken, it will take a lot of time to re-network, so the reliability and networking efficiency are relatively low

The present application provides a wireless communication method, device, and system, which relate to the technical field of wireless communication, wherein the method includes: receiving downlink data broadcast by a gateway or an upper-level wireless device, and the downlink data includes the identification information of the first target wireless device and the target instruction, and then judge the wireless device according to the identification information, if it is determined according to the identification information that the wireless device is the first target wireless device, then execute the target instruction; if it is determined according to the identification information that the first target wireless device is the next-level wireless device, then send Each lower-level wireless device corresponding to the wireless device broadcasts downlink data. The application can expand the application range, communication reliability and networking efficiency of the wireless communication system.
Description
technical field [0001] The present application belongs to the technical field of wireless communication, and in particular relates to a wireless communication method, device and system. Background technique [0002] With the vigorous development of wireless technology, the advantages of wireless technology are becoming more and more obvious. Many wired devices are gradually being replaced by wireless devices. [0003] The existing wireless devices communicate with the gateway in the wireless communication system in roughly two types: inquiry type and fixed path type. In the query communication method, the gateway must poll every moment whether each wireless device has a demand for data upload or delivery; when a wireless device has a data upload or delivery demand, the gateway needs to first Query the requirements of the wireless device, and then perform the corresponding upload or download operation. In the fixed-path communication method, it is necessary to configure the...
