Description

Novel quick inquiry card of plant protection unmanned aerial vehicle operation parameter

Technical Field

The utility model belongs to the technical field of unmanned aerial vehicle appurtenance, more specifically say, especially, relate to a novel quick inquiry card of plant protection unmanned aerial vehicle operation parameter.

Background

With the increasing maturity of brushless motors and brushless motor drivers (also called electronic speed regulators), electrically-driven small-sized civil unmanned aerial vehicles are made available, and the wide application of the unmanned aerial vehicles in various industries, such as aerial photography, plant protection, film and television shooting, agriculture and even regional security is further expanded.

At present, the most used and successful unmanned aerial vehicles should be plant protection unmanned aerial vehicles suitable for agriculture, and the pesticide spraying unmanned aerial vehicles with loads of tens of kilograms are mainly used in the application of the plant protection unmanned aerial vehicles. This type of unmanned aerial vehicle usually concentrates the operation in a certain fixed planting window period, and this just needs unmanned aerial vehicle flight hand to set for parameters such as unmanned aerial vehicle's flight control parameter, perception setting, remote controller setting before taking off. At present, the current practice of unmanned aerial vehicle complete machine manufacturers is to establish a data transmission link between an unmanned aerial vehicle MCU and an operation terminal, and then set downloading and displaying of parameters between the unmanned aerial vehicle and the MCU through a private communication protocol and private parameter debugging logic. However, this method can only interact with some data such as flying height, track, position, etc., and cannot provide an effective human-machine interaction medium for parameters such as soft start, motor angle approach, battery type, low-voltage protection, etc. of a speed regulator driving a brushless motor, which are critical to flight safety. Meanwhile, for unmanned aerial vehicle integration enterprises with some production modes mainly based on purchasing, parts and even all parts are obtained through purchasing, a unified data link technology is not available, and the unmanned aerial vehicle flyer can not provide a condition for reading unmanned aerial vehicle parameters, namely a human-computer interaction interface between the unmanned aerial vehicle and the flyer can not be provided.

Unmanned aerial vehicle brushless motor driver, its essence and alternating current motor converter are the same basically, and the difference lies in receiving unmanned aerial vehicle extremely to be leaded to the lightweight requirement, can not set up human-computer interaction module on the body like the converter. At present, the current practice in the industry is to use a processor of a driver to drive a motor to shake so as to realize sound production, the method is similar to an electronic speed regulator produced by Haoying or Mitsui corporation, different sounds are generated by the electronic speed regulator to represent different parameters, and man-machine interaction is further realized by changing the shaking frequency, and the method is recorded in the product specifications of the company products. However, this method is a compromise between the weight reduction of the product and the necessary functions, but the sound generated by the motor is sometimes difficult to be recognized by the user due to the influence of the use environment. Obviously, the above company has also recognized the existence of this problem, and has introduced an electronic tuning setting card with screen display for specific products only, which card displays the parameter information of the driver on the setting card by means of the lamp bead by establishing a physical data link between the driver and a lamp bead display, and its essence is the same as that of the existing transducer with screen, except that the display device is detachable. But a specific entity communication link and a private communication protocol must be used, so that a new barrier is brought to maintenance and upgrading of the unmanned aerial vehicle to protect user investment, and the unmanned aerial vehicle is not a universal solution for 8205.

Chinese patent CN214376039U discloses a novel electronic speed regulator which uses BEC to generate voltage fluctuation to represent driver parameters, although this method changes the traditional man-machine interaction mode, it is difficult to apply the scheme of integrating BEC on the driver in large-scale unmanned aerial vehicle products represented by plant protection unmanned aerial vehicles, because most of these products bear tens of kilograms, its driver usually adopts 24v or even 48v high voltage direct current input, and BEC usually provides 5v or 3.3v low voltage for the low voltage components such as MCU on the unmanned aerial vehicle, so large transformation ratio is difficult to realize in the dc power supply system using semiconductor, and its saturation voltage drop and semiconductor power loss, even heating are the non-negligible problems. And the brushless motor driving system of the existing large unmanned aerial vehicle adopts independent BEC or low voltage, and is independently powered by a battery, which just proves the point. More importantly, although the method adopts a technical scheme different from other products in the market, the method depends on BEC to generate fluctuating voltage, and then uses an electric regulation setting card to read the fluctuating voltage to display on a human-computer interaction interface, and the method and the modes of reading the high and low levels output by an electric regulation processor and then displaying on the human-computer interface by other setting cards need entity communication circuit connection, are limited by communication types or protocols, and still can not enable the setting card to realize universality on any unmanned plane type. Therefore, the field is in need of the appearance of a universal unmanned aerial vehicle parameter query device which is low in cost and suitable for outdoor operations such as fields, namely a human-computer interaction interface of a universal unmanned aerial vehicle.
