Collision avoidance system
A collision avoidance system for aircraft. A light fixture assembly includes a housing with a base and a clear dome over the base. The base including an aircraft attachment element that allows for drop-in replacement of original light housings. An aircraft light is within the housing, as well as an ultrasonic sensor. The sensor is tied to a warning indicator configured to issue an alert when the light fixture approaches an obstacle. The installation provides a permanent replacement for wing lights or taillights, whereby the proximity sensors are always on the aircraft, and do not need to be added once landed.
1. A collision avoidance system for aircraft comprising:
a plurality of ultrasonic sensors positioned around the aircraft and configured to be integrally fixed to the aircraft, wherein each of the plurality of ultrasonic sensors is integrated within a corresponding wingtip light or taillight fixture of the aircraft;
a three-position cockpit switch, comprising an enabled mode, a disabled mode, and a standby mode;
a warning indicator when the aircraft approaches an obstacle; and
an electronic control unit connected to the plurality of ultrasonic sensors, the three-position cockpit switch, and the warning indicator, the electronic control unit including an antenna configured for wireless connectivity of the electronic control unit to a mobile device; and
a mobile device app for the mobile device;
wherein the collision avoidance system operates in a towing mode adapted to provide warnings of detected objects via the mobile application operated by a ground crew, and the electronic control unit, the plurality of ultrasonic sensors, and the warning indicator operates in the standby mode when the aircraft is powered off, thereby allowing the plurality of ultrasonic sensors to warn when another object is close to the aircraft when the aircraft is parked.
2. The collision avoidance system of claim 1 , wherein the ultrasonic sensors comprise ultrasonic transducers.
3. The collision avoidance system of claim 1 , wherein the ultrasonic sensors comprise a 0.1 m to 20 m detection range, with 1 cm resolution.
4. The collision avoidance system of claim 1 , wherein the warning indicator comprises an audio piezo module.
5. The collision avoidance system of claim 1 , wherein the mobile device application comprises a smart phone app wirelessly paired with the system, wherein the smart phone app provides a visual warning indication and an audible warning indication.
6. The collision avoidance system of claim 1 , wherein the warning indicator comprises a flashing mode for a taxi light.
7. The collision avoidance system of claim 1 , wherein the plurality of ultrasonic sensors detect a proximity of a landing strip during landing and ground obstacles during ground movement.
8. The collision avoidance system of claim 1 , further comprising a secondary battery power supply configured to power the system in the standby mode when the aircraft is not operating.
9. The collision avoidance system of claim 1 , wherein the plurality of ultrasonic sensors include a downward directed sensor and the collision avoidance system operates in a landing mode adapted to provides warning indications of a landing strip.
10. The collision avoidance system of claim 1 , further comprising an adapter base, wherein the adapter base includes at least one of the plurality of ultrasonic sensors and is configured to attach between a light fixture and a wing or tail of the aircraft.
11. A collision avoidance system for aircraft comprising:
a light fixture assembly comprising a housing including a base and a clear dome over the base, the base including an aircraft attachment element;
an aircraft light within the housing,
an ultrasonic sensor within the housing;
a three-position cockpit switch connected to the electronic control unit, the cockpit switch comprising an enabled mode, a disabled mode, and a standby mode;
a warning indicator in combination with the ultrasonic sensor, and configured to issue an alert when the light fixture approaches an obstacle;
an electronic control unit wired or wirelessly connected to the ultrasonic sensor and the warning indicator the three-position cockpit switch, and the warning indicator, the electronic control unit including an antenna configured for wireless connectivity of the electronic control unit to a mobile device; and
a mobile device application for the mobile device;
wherein the collision avoidance system operates in a towing mode adapted to provide a warning of a detected objects via the mobile application operated by a ground crew, and the electronic control unit, the ultrasonic sensor, and the warning indicator operates in the standby mode when the aircraft is powered off, thereby allowing the ultrasonic sensor to warn when another object is close to the aircraft when the aircraft is parked.
12. The collision avoidance system of claim 11 , wherein the aircraft light is selected from a navigation light, a position light, a taxi light, an anti-collision light, or a landing light.
13. The collision avoidance system of claim 11 , wherein the light fixture assembly is a drop-in replacement for an original equipment light assembly.
14. The collision avoidance system of claim 11 , wherein the light fixture is a wingtip light or a taillight.
15. The collision avoidance system of claim 11 , further comprising a secondary battery power supply configured to power the system in a passive operation state when the aircraft is not operating.
16. The collision avoidance system of claim 11 , further comprising engine sensors connected to the electronic control unit.
17. The collision avoidance system of claim 11 , wherein the warning indicator comprises at least two of: an audio piezo module mounted in the aircraft cowling, a smart phone app wirelessly paired with the system, and a flashing taxi light.
