AI Technical Summary

Technical Problem

The Bluetooth temperature monitoring network inside the energy storage cabinet suffers from signal source identification bias, unstable reachability determination under structural obstruction conditions, and reliance on experience for deployment and parameter selection, making it difficult to ensure the reliability of key measurement points. This results in communication blind spots and unstable online rates.

Method used

By setting up a Bluetooth gateway and connecting an external antenna in the Bay position of the energy storage cabinet, a three-dimensional radiation pattern is obtained using full-wave electromagnetic simulation or actual measurement methods to determine the effective radiation starting point, establish a real signal radiation source model, and calculate the signal reachability and importance level by combining the energy storage cabinet structural information and the location of temperature monitoring nodes. The antenna orientation and transmission power configuration are then optimized to achieve reliable communication at key measurement points.

Benefits of technology

It achieves more stable temperature monitoring data transmission under the strong shielding of the metal structure of the energy storage cabinet, reduces the reliance on repeated trial installations and experience-based parameter adjustments, reduces the workload and maintenance costs of on-site commissioning, and improves the communication reliability of key temperature measurement points.
