The missile digital electrical system uses the microprocessor as the control and detection center of the missile electrical system. The system adopts full address decoding, expands 8 A / D acquisition channels, 24 I / O control channels and an asynchronous serial communication port for communication with the mission machine on the bomb. The asynchronous serial communication port of the microprocessor is used for communication with the onboard telemetry system. The expanded system meets the data collection, automatic control and automatic detection requirements of the missile electrical system. For the first time in the domestic missile electrical system, the functions of intelligent power distribution, on-demand distribution of missile electrical energy, automatic detection of key components of the missile electrical system, and automatic upload of detection results have been realized. It improves the reliability of the missile electrical system, meets the requirements of the troops for inspection and maintenance without opening the box, greatly reduces the maintenance workload of the troops, and also reduces the testing time of the missiles. It has high military significance.
Description
technical field [0001] The invention relates to a missile digital electrical system, which belongs to the technical field of electrical system design. The system is a missile electrical system integrating intelligent power distribution and automatic detection. Background technique [0002] The traditional missile electrical system design method only designs the missile electrical system as a single power transmission and distribution system, which requires the missile control system to control it and the telemetry system to detect the results of its execution. Especially after the standardization of the missile electrical system, there is no special electrical circuit test port. After the missile is equipped with the troops, the key components of the electrical system such as the relay cannot be tested. After the missile is stored for a long time, the reliability of the electrical system can be guaranteed. Secondly, the electrical systems of domestic missiles are now design...
