* @brief 继电器控制模块实现
|

|
|
* @author Application Layer
|

* @version 1.1
|

******************************************************************************

* @attention
|
|||
|
|
* 本模块实现继电器的安全控制
|
|||
|
|
* 关键特性：
|
|||
|
|
* 1. 最小切换间隔保护，防止频繁切换损坏继电器
|
|||
|
|
* 2. 状态记录，支持诊断
|
|||
|
|
* 3. 调试日志输出
|
|||
|
|
*
|
|||
|
|
* 修订历史：
|
|||
|
|
* v1.1 - 修复审查报告中危-9/10：对齐RELAY_COUNT与参数校验逻辑
|
|||
