Embodiment Construction
[0023] The method for preventing fire-fighting aircraft from accidentally touching overhead lines in the case of thick smoke provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] Such as image 3 As shown, the method that prevents fire-fighting aircraft from accidentally touching overhead lines under the thick smoke situation provided by the present invention comprises the following steps carried out in order:
[0025] Step 1) Initial setting stage: install indicating devices on the transmission lines between overhead towers, and all indicating devices shall be installed according to a unified standard, that is, red, green and red indicating devices shall be arranged at different positions on the transmission lines between overhead towers ; At the same time, using the computing and processing capabilities of the aircraft driving system, implant the formula 1 to formula 3 programs cor...

The invention relates to a method for preventing a fire aircraft from mistakenly touching an overhead line in dense smoke. The method includes the following steps that: indication devices are installed on a power transmission line between overhead towers; if a pilot drives the fire aircraft to perform an actual fire fighting flight, if the pilot sees a red indication device before, the pilot drives the fire aircraft at a maximum speed provided by a formula 1, and drives the fire aircraft overhead the indication device so as to fly over the overhead line; if the pilot sees a green indication device, the pilot drives the fire aircraft at a maximum rising speed provided by a formula 2, and drives the fire aircraft overhead the indication device so as to fly over the overhead line; if the pilot sees a red indication device and a green indication device simultaneously, the pilot drives the fire aircraft at a maximum rising speed provided by a formula 3, and drives the fire aircraft overhead the indication devices so as to fly over the overhead line; and a flight is repeated. The method of the invention is suitable for realizing a fighting aircraft warning effect in different mission areas in dense smoke. The method has the advantages of low cost and convenient installation and maintenance.
Description
technical field [0001] The invention belongs to the technical field of forest fire-fighting plane avoidance transmission lines, and in particular relates to a method for preventing fire-fighting planes from touching overhead lines by mistake in the case of thick smoke. Background technique [0002] When firefighting planes are carrying out forest firefighting tasks, they will face the danger of contact because the power transmission lines are near the temporary firefighting and rescue routes. Especially when a forest fire breaks out, the dense smoke produced will block the pilot's sight line, thereby making it more difficult for the pilot to observe with the naked eye. Once the driver is careless, the plane will crash easily, resulting in heavy property and loss of life. Even if a radar system is used for detection, due to the small cross-section of the wire and the high degree of roughness of identification, there will be greater work risks. Therefore, in order to safely c...
