[0025] The following is combined with Figure 1-2 This application is described in further detail.

[0026] The embodiment of the present application discloses a multi-parameter monitoring device for an unmanned aerial vehicle.

[0027] Reference Figure 1 The UAV multi-parameter monitoring device includes an environmental monitoring module 1, a transmission unit 2 and a modular function box 3.

[0028] Among them, the environmental monitoring module 1 includes a temperature sensor, and also includes one or more of a humidity sensor, an acceleration sensor, and a noise decibel sensor to meet the needs of temperature and humidity monitoring, vibration monitoring, and noise monitoring respectively.

[0029] There are two options for transmission unit 2:

[0030] The first type is the wire;

[0031] The second type is a wireless communication unit. Taking a drone that supports WIFI transmission as an example, the transmission unit 2 can be a matching WIFI unit.

[0032] Based on the above, in one case, the sensor of the environmental monitoring module 1 can be connected to the main control unit of the drone through a wire; in another case, the environmental monitoring module 1 is connected to the main control unit or remote control of the drone by wireless communication.

[0033] The modular function box 3 is arranged on the outer wall of the fuselage of the drone. The modular function box 3 includes a base 31 and a box body 32. The base 31 can be fixed to the bottom of the drone by bolts. The main body of the base 31 is a plate structure, and an internal threaded tube 311 is formed downward in the middle of its lower part. The box body 32 has an elliptical longitudinal section, and an opening facing the outside is provided at its lower part, and a cover plate 321 is fixed to the opening; a threaded column 322 is provided at the upper part of the box body 32, and the threaded column 322 is threadedly connected to the internal threaded tube 311.

[0034] In order to meet the demand for temperature detection inside the drone, the base 31 has an internal opening facing the internal threaded tube 311, and the threaded column 322 has a probe hole along the length direction. The probe hole fixes the bracket, and the probe of the temperature sensor of the environmental monitoring module 1 is fixed on the bracket; at this time, it is only necessary to open a hole in the drone body above the base 31 to connect to the inside, so that the temperature inside the drone can be detected, so that it can be discovered in time when the electronic components are burned out or overloaded and heated.

[0035] It is understandable that the noise decibel sensor can be installed in the same manner as described above, and the acceleration sensor can be built into the box body 32. After all, the vibration of the drone will drive the box body 32 connected thereto to vibrate.

[0036] Because the box body 32 and the base 31 are threadedly connected, in order to prevent the UAV from rotating during flight and the box body 32 from rotating relatively due to inertia, causing the connection to loosen, a locking mechanism 4 is installed at the bottom of the base 31, and the locking mechanism 4 includes a guide tube 41, a telescopic rod 42 and a spring 43.

[0037] The conduit 41 extends toward the box body 32 , the telescopic rod 42 is inserted into the conduit 41 and is slidably connected, one end of the spring 43 is fixed to one end of the telescopic rod 42 located in the conduit 41 , and the other end is fixed to the conduit 41 .

[0038] A positioning hole is formed on the box body 32 , and the telescopic rod 42 is inserted into the positioning hole.

[0039] When installing the box body 32, the telescopic rod 42 is first prevented from being inserted into the positioning hole on the box body 32. When the box body 32 is rotated and screwed into place, the telescopic rod 42 is no longer blocked from extending under the action of the spring 43. At this time, the telescopic rod 42 is inserted into the positioning hole on the box body 32, thereby preventing the box body 32 from rotating relative to the base 31, that is, preventing the connection from loosening.

[0040] In order to facilitate the installation of the box body 32, a rotating shaft is fixed to the side of the positioning hole of the box body 32, and a blocking piece 323 is rotatably connected to the rotating shaft. The blocking piece 323 can at least rotate to the outer port of the positioning hole and the side of the positioning hole. The blocking piece 323 has a protrusion on the side away from the box body 32.

[0041] According to the above arrangement, before the box body 32 is tightened, the staff can cover the positioning hole with the blocking piece 323 to prevent the telescopic rod 42 from being inserted into it in advance. During the process, the staff touches the protrusion on the blocking piece 323 with their fingers to determine the position and press the blocking piece 323 to prevent it from rotating at will.

[0042] Reference Figure 2 In one embodiment of the present application, a battery and a voltage conversion module are installed in the box body 32. In this embodiment, the battery can be a lithium battery. Assuming that the output of the lithium battery is 3.3V, and most sensors require 5V, a voltage conversion module is also required at this time, and the voltage conversion module includes a DC boost circuit, and the DC boost circuit includes:

[0043] The transistor vibration circuit includes: a transistor Q1 and a resistor R1, the transistor base is connected in series with the resistor R1 and connected to the end of the primary side of the transformer T; the emitter of the transistor Q1 is connected to the regulating head of the transformer T, assuming it is the middle; the collector of the transistor Q1 is connected to the starting end of the primary side of the transformer.

[0044] The voltage stabilizing rectifier circuit comprises a diode D1, a voltage stabilizing diode D2, a resistor R2, a capacitor C1 and a capacitor C2; the positive end of the diode D1 is connected to the starting end of the transformer T, and the negative end is connected in series with the resistor R2; one end of the capacitor C1 is connected to the connection point of the diode D1 and the resistor R2, and the other end is connected to the secondary side end of the transformer T; the positive end of the voltage stabilizing diode D2 is connected to the connection point of the capacitor C1 and the transformer T, and the negative end is connected to the resistor R2, and the capacitor C2 and the voltage stabilizing diode are connected in parallel; and the two ends of the capacitor C2 serve as the DC output positive and negative ends for supplying power to each sensor.

[0045] In order to enable this application to be automatically enabled when the drone is started, a micro relay is further integrated in the box body, denoted as K; the coil of the micro relay K is connected in series with the power supply module of the drone, and the normally open contact is connected in series with the collector or emitter of the above-mentioned transistor Q1; the collector is taken as an example in the figure. According to the above settings, when the drone is powered on, this application is also powered on and works.

[0046] In another embodiment of the present application, in order to determine whether the box body 32 is installed in place and verify whether the function of the drone triggering the power-on of the present application is normal, the telescopic rod 42 is set to a metal rod, and an LED light is embedded and installed on the box body 32, and the position can be the side wall; two separate conductive plates 5 are fixed at the inner end of each positioning hole, and the LED light is connected in series to the two conductive plates 5, and the conductive plate 5 is also connected in series to the coil of the micro relay through a wire.

[0047] According to the above configuration, if everything is normal, the two conductive plates 5 at the ends of the same positioning hole are abutted by the metal telescopic rod 42 inserted into the positioning hole, achieving conduction. At this time, current flows through the coil of the micro relay, the conductive plate 5, and the LED lamp, and the LED is lit.

[0048] If the box body 32 is not installed in place, the telescopic rod 42 is separated from the conductive plate 5, and the LED light is not on.

[0049] If the drone does not power the micro relay coil, the LED light will not light up.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
