Abstract

一种信号检测电路及车载电脑。车载电脑包括连接器(J1)，通过输入引脚(11)接收第一信号或第二信号，通过输出引脚(12)输出第一信号或第二信号；处理器(10)包括第一(1)及第二输入输出引脚(2)；第一检测电路(20)，输入端连接输出引脚(12)，接收第一或第二信号，输出端连接第一输入输出引脚(1)，输出第一检测结果给处理器(10)；第二检测电路(30)，输入端连接输出引脚(12)，接收第一或第二信号，输出端连接处理器(10)的第二输入输出引脚(2)，输出第二检测结果给处理器(10)，处理器(10)根据第一及第二检测结果判断接收到的是第一或第二信号，以此简化了电路并减少了引脚数量，节省开发时间及成本。
