Dual Communication Module for Logistics Container Data Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Logistics containers face challenges in maintaining real-time communication with servers while minimizing power consumption, as existing solutions either lose timeliness or increase power usage due to prolonged sleep times.
Innovation Solution
Implementing a dual communication module system in logistics containers, where a short-range module detects nearby containers and wakes up the remote communication module only when necessary, allowing timely data reporting with reduced power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the wireless terminal increases sleeping time to reduce power consumption, then power consumption is reduced, but communication timeliness deteriorates
Solution Approach 1:
The wireless terminal is segmented into two communication modules: a first communication module (short-range, low power) and a second communication module (long-range, high power). The first module remains active for local wake-up signals while the second module sleeps, dividing the communication functions to resolve the contradiction between power saving and timely response.
Solution Approach 2:
The first communication module performs preliminary monitoring and wake-up detection before the second communication module needs to activate. By continuously listening for wake-up signals through the low-power first module, the system prepares for timely communication without keeping the high-power second module active, thus maintaining responsiveness while saving energy.
2Loss of time
If the wireless terminal maintains continuous connection to ensure real-time communication, then communication timeliness is improved, but power consumption increases
Solution Approach 1:
The communication system is divided into two modules with different power consumption characteristics. The first communication module consumes minimal power and can operate continuously for wake-up detection, while the second module consumes more power but remains in sleep mode most of the time, activating only when needed for actual data transmission.
Solution Approach 2:
The first communication module acts as an intermediary between the external environment and the second communication module. It receives and processes wake-up signals, then activates the second module only when necessary, mediating between the need for continuous monitoring and the need to conserve power in the main communication module.
3Use of energy by moving object
If the terminal uses short-range communication module for wake-up detection, then power consumption is reduced, but communication distance is limited
Solution Approach 1:
The communication system segments functions by distance: the first communication module handles short-range wake-up signals with low power consumption, while the second communication module handles long-range data transmission with higher power consumption. This segmentation allows each module to operate in its optimal range and power mode.
Solution Approach 2:
The system dynamically switches between communication modules based on operational needs. The first module operates continuously at low power for local wake-up detection, while the second module dynamically activates only when long-range communication is required, adapting the communication distance capability to actual needs without continuously consuming high power.

AI summary
This application relates to the field of logistics, and discloses a data reporting method and system for logistics containers. Each logistics container is provided with a terminal, and the terminal includes a first communication module and a second communication module. The server sends a first message to the second communication module of the first terminal; when the second terminal communicates with the server through its second communication module, it reports the identification of other surrounding terminals detected by the second terminal through its first communication module to the server; if the server detects that the reported identifier includes the identifier of the first terminal, it sends a second message to the second terminal; In response to the second message, the second terminal wakes up the second communication module of the first terminal through its first communication module; The first terminal communicates with the server through its second communication module, and receives the first message. This application can realize the timely and on-demand reporting of data to the server by the logistics container under the condition of low power consumption, which reduces the labor cost and material cost of the management of the logistics container.
