AI Technical Summary

Technical Problem

The prior art lacks adaptive solutions for using passive terminals for passive IoT communication, resulting in the inability to effectively use multiple energy sources for communication.

Method used

By setting the first energy collection module and the second energy collection module at the terminal, the required energy demand reported according to the service data, the operation is selected in the first mode or the second mode. The first mode uses the first energy to communicate, while the second mode uses the first energy and the second energy to communicate, ensuring that the energy demand is met.

Benefits of technology

It realizes the selection of appropriate working modes based on the terminal's business data and energy collection situation, ensures the stability and reliability of passive Internet of Things communication, and at the same time, rationally utilizes a variety of energy sources to save energy resources.

Abstract

The invention provides a passive Internet of Things communication method and device, electronic equipment and a storage medium, and relates to the technical field of wireless communication. The method comprises the following steps: in response to service data reported by a terminal, determining first energy collected by a first energy collection module and service demand energy; in response to the fact that the first energy is greater than or equal to the business demand energy, controlling the terminal to work in a first mode and reporting uplink information carrying business data to the base station by using the first energy; in response to the fact that the first energy is smaller than the service demand energy, sending an uplink signal to the base station to request a radio frequency to supply energy to a second energy collection module to collect second energy; and controlling the terminal to work in the second mode, and reporting the uplink information to the base station by using the first energy and the second energy. According to the invention, the terminal can be selected to work in different modes according to the business data and the energy storage conditions of the first energy collection module and the second energy collection module, thereby guaranteeing the communication of the passive Internet of Things, and saving the energy resources.
