Ⅰ. Overview
With the advancement of the "dual carbon" goal, the new power system is accelerating its transformation towards intelligence, distribution and high reliability. In this process, wireless communication technology has become the core support for realizing device interconnection, real-time data transmission and remote control. Chengdu Yibite Electronic Technology Co., Ltd. (hereinafter referred to as "Yibite") has been deeply involved in the field of Internet of Things communications for many years. Its wireless module products provide efficient and reliable wireless solutions for new power systems with high stability, long-distance coverage, low power consumption and flexible networking capabilities.
Ⅱ. The core of wireless power system
The new power system needs to cope with complex scenarios:
① Wide area coverage: transmission line monitoring, substation equipment management, etc. need to cover a range of several kilometers to tens of kilometers;
② Anti-interference ability: high-voltage electromagnetic environment and complex terrain are prone to signal attenuation;
③ Low power consumption and real-time: smart meters and distributed energy terminals need to be on standby for a long time and respond quickly;
④ Network reliability: multi-node networking needs to support redundant links and automatic repair functions.
Relying on LoRa spread spectrum, Mesh networking, high-power RF design and other technologies, Ebyte has launched a number of wireless module products that are suitable for power scenarios.
Ⅲ. Recommended products of Ebyte wireless modules
