The invention discloses a method and a device for preventing a CPU local bus from suspension. The method comprises a step of constructing a TA signal in accordance with a CPU time sequence and transmitting the TA signal to a CPU when a logic processing unit of slave equipment determines that the slave equipment is time-out and does not transmit the TA signal. The device comprises the CPU, the slave equipment and the logic processing unit of the slave equipment which are connected sequentially, wherein the logic processing unit of the slave equipment is used for constructing the TA signal in accordance with the CPU time sequence and transmitting the TA signal to the CPU when determining that the slave equipment is time-out and does not transmit the TA signal. The method and the device are applicable to application of providing the TA signal by using the slave equipment to prevent the CPU local bus from suspension, and can position failure equipment to avoid failure diffusion and improve system stability.
