In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
Examples
This embodiment provides a control box of reporting an emergency and asking for help or increased vigilance for helicopter topography perception and warning system, including casing and controller, the controller sets up in the casing, be provided with the control panel who links to each other with the controller on the casing, the controller includes light display module and system control module, light display module with system control module links to each other, just light display module with system control module with it links to each other to report an emergency and ask for help or increased vigilance the computer.
In this embodiment the light display module includes topography pilot lamp, pull-up pilot lamp and system failure pilot lamp, topography pilot lamp, pull-up pilot lamp and system failure pilot lamp set up on control panel.
a) Topographic indicating lamp
When the aircraft enters each model guard boundary, triggering guard level alarm, lighting an amber terrain indicator lamp, and lighting the terrain indicator lamp for a long time in alarm conditions; when the system determines that the aircraft is out of the armed level alert boundary, the terrain indicator light is extinguished.
b) Pulling-up indicator lamp
When the airplane enters the warning boundary, the system continuously sends out a pull-up warning voice, meanwhile, a red pull-up indicator lamp is lightened, and the pull-up indicator lamp is lightened for a long time in the warning condition; when the system determines that the aircraft is out of the warning level warning boundary, the "pull-up" indicator light is extinguished.
c) 'system failure' indicator light
When the computer fails to provide data to the warning computer or the system fails, the warning system cannot work normally, and the warning computer transmits a signal of system failure to the light display module, so that a system failure indicator lamp is turned on; when the data on the alarm system receiver is normal, the 'system failure' indicator lamp is turned off.
