Abstract

The invention discloses a management and control circuit and method for aircraft initiating explosive devices, and relates to the technical field of initiating explosive device management and controlprotection. The management and control circuit comprises a plurality of initiating explosive device groups, a plurality of first electromagnetic relays, a plurality of solid-state relays and a main controller, wherein the main controller is configured as follows: when the initiating explosive devices are stored or transported, the main controller controls all first electromagnetic relays to act soas to enable the two ends of each initiating explosive device to be grounded; during measurement of the loop resistance of the initiating explosive devices, the main controller controls all the firstelectromagnetic relays to act, so that each initiating explosive device can be connected with the output end of a control switch of the corresponding solid-state relay, and the input ends of all thecontrol switches are controlled to be connected with a constant-current source; and during use of the initiating explosive devices, the main controller controls all the first electromagnetic relays toact, so that each initiating explosive device can be connected with the output end of the corresponding control switch, and the input ends of all the control switches are controlled to be connected with a direct-current power source. According to the management and control circuit and method, manual on-site operation of short-circuit protection plugs or access plugs is not needed, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of control and protection of pyrotechnics, in particular to a control circuit and method for aircraft pyrotechnics. Background technique [0002] Aircraft pyrotechnics and its control circuit are important components of the aircraft. The pyrotechnics on the aircraft include engine pyrotechnics, stage separation pyrotechnics, shroud throwing pyrotechnics, and self-destruct pyrotechnics. All kinds of pyrotechnics need to detonate normally according to the requirements in order to realize the normal flight of the aircraft. In order to ensure the safety of the entire application cycle of the aircraft pyrotechnics: when the aircraft pyrotechnics are stored, short-circuit protection is required to ensure that the pyrotechnics will not be activated by mistake; before the aircraft is launched, the aircraft pyrotechnics need to be tested, And when performing the detection process, it is necessary to remove the short...
