Built-in load switch control circuit with mutually exclusive control signals and control method

The invention relates to a built-in load switch control circuit with mutually exclusive control signals and a control method, through connecting input control signals in a mutually exclusive manner, the condition that an electric energy meter is damaged due to simultaneous conduction of an optocoupler when a switching-off control signal and a switching-on control signal are simultaneously at a high level is directly avoided from hardware, and the reliability of the electric energy meter is improved. And meanwhile, the complexity of software design is reduced. 本发明涉及一种控制信号互斥的内置负荷开关控制电路以及控制方法，通过将输入控制信号以互斥方式连接，从硬件上直接避免了拉闸控制信号和合闸控制信号同时为高电平时导致光耦同时导通，从而导致电能表损坏的情况发生，同时减少了软件设计的复杂性。
