Hanging point node RT address allocation control method in distributed hanging object management system

Abstract

The invention provides a hanging point node RT address allocation control method in a distributed hanging object management system. The method comprises the steps: employing a time-sharing one-by-onepower-on control mode, reading hanging point node interlocking signals one by one after a central control node is powered on, controlling the hanging point node to be powered on after the existence ofthe hanging point node is recognized, and controlling the hanging point node to be powered off; then establishing communication with the hanging point node according to a default RT address, and after the communication is normal, setting a new RT address of the hanging point node by the central control node through a GJB289A bus; after the central control node polls all the hanging point nodes, automatically acquiring new RT addresses by all the hanging point nodes, and then entering a working mode according to the new RT addresses. The number of signals between the central control node and the hanging point node on the distributed hanging object management system is reduced, and therefore the size and weight of a cable connected between the central control node and the hanging point nodecan be reduced.

Description

technical field [0001] The present invention relates to the field of aircraft avionics, in particular to a communication control method in a suspended object management system, which is used for when the hanging point node and the central control node in the configuration of the distributed hanging object management system communicate through the GJB289A bus, the hanging point node Automatic allocation control of RT addresses. Background technique [0002] Suspension management system is an important part of the avionics system of combat aircraft, which is used to complete the control of various types of suspensions carried by the aircraft (guided / unguided bombs, air-to-air missiles, air-to-surface missiles, aircraft guns, rockets and various types of suspensions). Class) status identification and launch control management. From the perspective of physical or functional configuration, suspended object management system is generally divided into two basic configurations: cen...

Problems solved by technology

[0005] Since the central control node and the hanging point node are installed in different positions on the combat aircraft (the central control node is generally installed in the aircraft equipment compartment, and the hanging point node is generally installed on the wing near the pylon position), it will cause the connection between the central control node and the hanging point node. Complicated routing of cables between nodes and excessive weight
