Description

[0001] AUXILIARY APPARATUS FOR DRONE [0002]

The present invention relates to a power system for a quad-copter as an auxiliary device for a drone. Further, another embodiment of the invention relates to a drones identification device using a mobile network.

Unlike the fixed-pitch type drones that occupy most of the current drones, the variable-pitch type drones have many advantages such as maneuverability, maximum take-off weight, and resistance to disturbance. On the other hand, in constructing a power transmission system through gears and drive shafts, manufacturing precision increases, manufacturing difficulty increases, and some power loss occurs during transmission. Also, a single power source in the center loses power if it loses power. It is possible to design various size aircrafts with the same structure, but there is also a problem that the power transmission system must be redesigned every time.

As the number of drones operating in the conventional industrial field or civilian area is increasing, the resulting privacy invasion, security, and direct safety problems are increasing. In particular, the DIY drones are not able to know the distribution route unlike the finished product, and can not grasp the specific performance specifications and logarithms (such as the recent North Korean drones).

Consumers also have inconveniences such as malfunction or reporting by others by using unregistered RF frequencies in using the drone. On the other hand, there is a national drones registration system (FAA, Korea Ministry of Land Transportation), but it is dependent on voluntary registration, and even in the case of registered drones, it is difficult to control the whole system system. There is a problem that can not be done.

Also, the conventional Open Source dron has a problem that a separate RF modem must be connected to the data link for flight monitoring. The RF modem can also receive the flight information of the drone by providing a corresponding modem on the user side. The use of the separate RF model in this way increases the number of equipments from the viewpoint of the user and the position of each dron can not be recognized by the institution or the government, which makes it difficult to manage the drones.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First Embodiment

The present invention comprises two power modules, a timing belt, a frame, and a PMU (Power Management Unit). Here, the power module consists of two sensored BLDC motors with identical specifications, clutch, belt pulley and frame, each sensored BLDC is a power system for a quad-copter with sub-PMU or ESC (Electric Speed Controller) . These power systems for quadrupoles can have the following characteristics.

1) Module configuration

It is possible to increase / decrease the power according to demand while maintaining the mount diameter by the core height variable h of the sensored BLDC. Free-Wheel operation when one-way or other unidirectional clutch bearings are applied to the rotor of each sensor BLDC and power is not applied. This allows other motors to share power when the motor is powered down.

2) Configuration of power system

The same module is used for the front and rear wheels, and the direction is controlled by the PMU or Sub PMU. The modules and modules are connected via a timing belt, which synchronizes the power distribution between the modules. And can correspond to various frames by the distance parameter d between modules.

3) Operation of power system

The interaction of the above structure does not cause a complete loss of power even when a maximum of three motors are stopped. Also, each module can maintain power even if a belt departs or is short-circuited. Even if all four motors are stopped, Free-Wheel operation does not lead to a sudden fall.
