Abstract

The invention discloses a communication system based on a LoRa technology, a gateway, a terminal and a communication method, and the system comprises the gateway which is used for sending a LoRa datapacket containing a preamble, and the sending duration of the preamble is n1; a terminal, used for carrying out channel activity detection with the time length of q1 once after sleep with the time length of p1 passes each time. If the lead code is not detected, the terminal continues to sleep with the time length of p1. If the preamble is detected, dormancy with the duration of p1 is continued after the data packet is received and processed, wherein p1 > q1, and p1 + q1 is smaller than or equal to n1. By applying the data bidirectional interaction method and device, in the application scene ofdata bidirectional interaction, it can be guaranteed that the terminal receives data in time, timely and effective interaction is achieved, and power consumption of the terminal device can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a communication system, gateway, terminal and communication method based on LoRa technology. Background technique [0002] LoRa is a long-distance wireless transmission technology based on spread spectrum technology. In fact, it is also one of many LPWAN communication technologies. It was first adopted and promoted by the American Semtech company. This solution provides users with a simple wireless communication method that can realize long-distance and low power consumption. At present, LoRa mainly operates in the ISM frequency band, mainly including 433, 868, 915MHz and so on. [0003] The advantage of LoRa (Long Range) lies in its technical long-distance capability. A single gateway or base station can cover an entire city or hundreds of square kilometers. At a given location, the distance depends heavily on the environment or obstacles. [0004] In order to...
