Abstract Due to the use of multi-interface module tile design technology in the PC104 computer system of Executive Control Device in Launch Control Equipment, the computerized standard data (CSD) serial board occasionally has a power-on reset problem. A filtering algorithm for the CSD serial board power-on reset has been designed. A hardware reset signal detection circuit was added, which was simulated and tested. The simulation and test results show that the software filtering algorithm and hardware circuit design can prevent the abnormal occurrence of power on reset and improve the reliability of serial communication of Launch Control Equipment.
