In order to ensure the information security of equipment and improve the level of autonomous control of equipment, a fire control computer is designed and implemented on a domestic hardware and software platform in certain type fire control system design. The selection and demonstration of the hardware and software platform are carried out, and a fire control computer based on Loongson 2H and DeltaOS is designed and implemented. Its hardware structure, software system and design key points are described in detail. The test results show that the fire control computer based on the domestic hardware and software platform can meet the requirements of certain type fire control system, and can supply engineering reference to similar system.
