Abstract

The invention relates to a start control system for an aircraft engine. A transfer printed board is connected with all printed boards through connectors and is mounted in a crate; a computer printed board comprises a 1394B processing circuit, a CPU (central processing unit) circuit and an RS422 and internet access circuit; an interface printed board is connected with the CPU circuit through a local bus; a discrete magnitude processing circuit is connected with a comprehensive electronic regulator; an analog quantity processing circuit is connected with an external engine; a power printed board is used for delivering power to every electrical component; and an output processing printed board is connected with the engine and the power supply of the CPU circuit. According to the start control system, integrated circuits are used for replacing electronic circuits of a conventional starting box, all control functions of a transmission starting box are achieved, and analog-digital conversion of partial analog quantity signals in modernized novel engines is completed.

Description

technical field [0001] The invention relates to a control system, in particular to an aircraft engine start control system Background technique [0002] In the modern aircraft engine starting control system, the starting box is required not only to be small in size and long in life, but also to be responsible for the analog-to-digital conversion of some analog quantities of the engine while completing the starting control, and to convert the signals required by the aircraft and the engine. 1394B communication. The traditional aircraft engine starting control is realized by the starter box, and all logic controls of the traditional starter box are all completed by electronic circuits including relays, which have the disadvantages of large volume and short life. Contents of the invention [0003] The purpose of the present invention is to provide an aircraft engine start control system, which has the characteristics of small size and long life, and can realize the analog-to...
