A heating control box detection device for aircraft windshield

Abstract

The invention belongs to testing technology, and relates to a detection device for an aircraft windshield heating control box. The heating control box detection device of the aircraft windshield includes an AC signal module, a DC display module, a resistance conversion module, and a connection output module, wherein the AC signal module for providing a three-phase current signal to the heating control box is used for The DC display module for providing DC signals to the heating control box and the resistance conversion module for providing resistance signals to the glass heating control box are independent of each other, and are respectively connected to the connection output module for providing output signals to the heating control box. The AC signal module includes a left three-phase AC transformer, a right three-phase AC transformer, a transfer switch, and an external load. The present invention uses a single-phase 115V power supply instead of a three-phase 115V power supply, and uses a single slider resistor instead of three load resistors, which effectively simplifies the detection circuit, reduces the production cost of the detection device, and makes the detection work easier to realize.

Description

technical field [0001] The invention belongs to testing technology, and relates to a heating control box detection device for aircraft windshield glass. Background technique [0002] Yun 8 There are 4 pieces of windshield glass for the driver before a certain model, they are the side glass of the left driver, the front glass of the left driver, the front glass of the right driver, and the side glass of the right driver. A single-phase 115V power supply is used to supply power to one temperature resistor inside the glass to realize the heating of four windshield glasses, ensuring that the pilot of the aircraft can observe the outside of the aircraft at high altitude. Starting from a certain model, the driver's windshield glass is changed from 4 pieces to 2 pieces, one piece for the left and right drivers, and each piece of glass is twice the size of the original one piece, so that the driver's high-altitude observation field outside the aircraft is significantly wider.

Problems solved by technology

Therefore, the existing single-phase 115V power supply mode and the configuration of a single resistive load can no longer meet the needs of the ground detection of the XJW-1 glass heating control box of a certain type of aircraft.
