Detailed Description

The present application is described in further detail below with reference to figures 2-7.

The embodiment of the application discloses an intelligent fault indication method for an unmanned aerial vehicle power system.

Referring to fig. 2 and 3, an intelligent fault indication method for an unmanned aerial vehicle power system includes the following steps:

s1: acquiring a plurality of state feedback signals of the power system;

specifically, the method comprises the following steps: the microcontroller obtains a plurality of state feedback signals including a motor voltage signal, a motor current signal, an accelerator signal, a MOSFET tube temperature signal and a capacitance temperature signal through a current (voltage) probe, a rotating speed sensor, a temperature sensor and the like which are arranged in an unmanned aerial vehicle power system;

s2: judging the plurality of state feedback signals, and outputting an abnormal result when the state feedback signals are abnormal;

specifically, the method comprises the following steps: the microcontroller is used for judging the plurality of state feedback signals, and the judging process is as follows: the microcontroller is preset with a plurality of signal reference value ranges, the state feedback signals are compared with the corresponding signal reference value ranges one by one to obtain abnormal results, the preset signal reference value ranges comprise a plurality of reference value ranges including a motor voltage signal reference value range, a motor current signal reference value range, an accelerator signal reference value range, a MOSFET tube temperature signal reference value range and a capacitor temperature signal reference value range, and the signal reference value ranges correspond to the state feedback signals one by one. For example, the motor voltage signal corresponds to a motor voltage signal reference value range, and the motor current signal corresponds to a motor current signal reference value range. The comparison process is as follows:

comparing the motor voltage signal with a motor voltage signal reference value range, and if the motor voltage signal is larger than any value in the motor voltage signal reference value range, outputting an abnormal sub-result of the motor voltage signal being too high; if the motor voltage signal is smaller than any value in the reference value range of the motor voltage signal, outputting an abnormal sub-result that the motor voltage signal is too low; if the motor voltage signal is any value in the reference value range of the motor voltage signal, the motor voltage signal is normal, and an abnormal sub-result is not output.

The abnormal sub-results also comprise a plurality of abnormal sub-results including overhigh motor current signals, overlow accelerator signals, overhigh temperature signals of the MOSFET tube, overhigh capacitance temperature signals, and the like, the abnormal sub-results are obtained by adopting the same comparison method, and the abnormal result is the sum of all the abnormal sub-results obtained at the current time.

S30: traversing the abnormal result through a preset fault indication table to obtain a fault type;

specifically, the method comprises the following steps: referring to fig. 2 and 4, a fault indication table is prestored in the microcontroller, a plurality of fault types, fault indication types and priority levels are stored in the fault indication table, and judgment conditions are also preset in the microcontroller, and the fault indication types, the priority levels and the judgment conditions all correspond to the fault types. The judgment condition is a combination of one or more abnormal sub-results, the fault types comprise various faults including overvoltage, undervoltage, overcurrent, accelerator loss, accelerator not returning to zero, over-high temperature of an MOSFET (metal oxide semiconductor field effect transistor) tube and over-high temperature of a capacitor, after the abnormal result is obtained, the fault indication table is traversed, the judgment condition of each fault type on the fault indication table is compared with the abnormal result, and if the abnormal result comprises the judgment condition, the fault type corresponding to the judgment condition is output.

S31: judging the number of fault types, after judging that the number of the fault types is multiple, reserving the fault type with the highest priority level, and deleting other fault types with low priority levels;

specifically, the method comprises the following steps: the priority levels corresponding to each fault type are different, for example, the priority level of overvoltage is 0, the priority level of over-high temperature of the MOSFET is 5, the higher the priority level is, the more serious the problem is, the more the problem needs to be processed as soon as possible, and after the fault types are output, the number of the fault types is judged. If the number of the fault types is more than one, the priority levels of all the fault types are found out by comparing with the fault indication table, bubbling sequencing is carried out to compare the sizes, the fault type with the largest priority level is reserved, and other fault types are deleted. Therefore, the personnel can find the most serious fault for maintenance quickly, and the microcontroller receives the state feedback signal all the time, so that after the most serious fault is eliminated, the fault type with the second priority level is automatically increased to the fault type with the maximum priority level and is reserved, and the personnel can eliminate the fault types one by one according to the severity of the fault. And after the number of the fault types is judged to be less than or equal to one, the fault types are not deleted.

S40: acquiring a corresponding fault indication type according to the fault type, and indicating the fault indication type in a sound and/or light mode;

specifically, the method comprises the following steps: referring to fig. 3 and 4, the fault indication type includes a fault bit sequence number and a fault code corresponding to the fault bit sequence number. The process of acquiring the fault bit sequence number is as follows: because the position of data in any table can be positioned by the horizontal and vertical cell values, after the cell position of the fault type in the fault indication table is determined, the cell where the corresponding fault position serial number is located can be found by adding or subtracting the cell values, and the fault position serial number in the cell is identified;

incidentally, in another embodiment, the fault bit sequence number may be further optimized to correspond to the priority level, so that the fault bit sequence number with the lower priority level is before, the fault bit sequence number with the higher priority level is after or before, and the fault bit sequence number with the lower priority level is after, for example, the fault bit sequence number with the priority level of 0 corresponds to 1, and the fault bit sequence number with the priority level of 8 corresponds to 9.

The fault code is formed by a fault bit sequence number and a preset specific value according to a supply formula: the a/B = C … … D is obtained by conversion, where the dividend a is a serial number of a fault bit, the divisor B is a specific value, the quotient C is an upper encoded value, and the remainder D is a lower encoded value, in this embodiment, the specific value is 5, and the upper encoded value and the lower encoded value jointly form a fault code. For example, the corresponding fault bit number 8 has a fault code value of 1-3, 1 being the upper code value and 3 being the lower code value. The failed bit sequence numbers collectively contain 1-16 for a total of sixteen sequence numbers to correspond to sixteen different failure types.

The specific process of indicating in the embodiment in a light manner is as follows: in one embodiment, the light indication needs to be performed through a light emitting device, the light emitting device adopts an RGB indicator lamp circuit, the RGB indicator lamp circuit is fixedly installed on a housing of the unmanned aerial vehicle power system, after the fault code is obtained, the microcontroller sends a first light flicker indication and a second light flicker indication according to the fault code, and the specific process of the first light flicker indication is as follows: the microcontroller controls the driver to send a corresponding number of long-time high-level signals to the RGB indicating lamp circuit according to the specific numerical value of the upper coded value, so as to control the RGB indicating lamp circuit to send light for a long time, namely, to carry out long-time light indication for many times, the duration of each sent long-time high-level signal is 1000ms, so that the time of the long-time light indication can also last 1000ms, after each long-time high-level signal is sent, the next long-time high-level signal is sent at a preset first interval, the value range of the first interval is 150 plus 350ms, in the embodiment, the first interval is 250 ms;

after the first light flicker indication is finished, a second light flicker indication is sent at a preset second interval, and the specific process of the second light flicker indication is as follows: according to the specific numerical value of the lower encoding value, the microcontroller can control the driver to send out short-time high-level signals of corresponding quantity to the RGB indicating lamp circuit so as to control the RGB indicating lamp circuit to send out light in short time, namely, the RGB indicating lamp circuit carries out multiple short-time light indication. The value range of the second interval time is 400-600ms, in this embodiment, the second interval time is 500ms, the duration of the short-time high-level signal sent each time is 100ms, so that the time of the short-time light indication lasts 100ms each time, after each short-time high-level signal is sent, the next short-time high-level signal is sent at a preset third interval time, and the value range of the third interval time is 150-350 ms. In this embodiment, the first interval time is 250 ms.

For example, after obtaining the fault codes of 1-3, the microcontroller controls the RGB indicating lamp circuit to perform four light indications, wherein the four light indications include one long-time light indication and three short-time light indications.

Referring to fig. 5 and 6, the level output manner of the microcontroller controlling the driver according to the fault code is shown for more comprehensive clarity. In this embodiment, signals output from the driver to the oscilloscope after acquiring the fault codes of 0-1 to 2-0 are shown, and the signals corresponding to the fault codes of 1-3 are the third signal from the right to the left in fig. 6.

After the second light flicker indication is finished, the first light flicker indication is sent out at a preset specific time interval according to the upper code value, and the value range of the specific time interval is 2500-3500 ms. In this embodiment, specific time quantum is 3000ms to make RGB pilot lamp interval 3 seconds time, carry out light indication once to the fault type, repeatedly instruct personnel, ensure that personnel can know the fault type, the discernment degree of RGB pilot lamp is higher simultaneously, and its colour is distinguished from the natural light, and the personnel of being convenient for see the pilot lamp clearly.

In another embodiment, the specific process of indicating in a lighting manner is as follows: after the RGB indicating lamp acquires the fault code, the microcontroller can directly control the RGB indicating lamp to emit light with different colors according to the fault code, so that personnel can judge the fault type of the power system according to the light color.

In this embodiment, the specific process of indicating in a voice manner is as follows: the sound generating device adopted by the sound indication can be a motor or a buzzer, after the fault code is obtained, the microcontroller can output a long-time high-level signal and a short-time high-level signal to the sound generating device according to the fault code after the fault code is obtained, the output modes of the long-time high-level signal and the short-time high-level signal are the same as the output modes in the specific process of indicating in a light indication mode, and therefore the motor or the buzzer is controlled to send out sound at intervals, for example, when the fault code is 1-3, the buzzer sends out 1 long-time sound with the duration of 1000ms, the interval of 500ms and 3 short-time sound with the duration of 100ms, the interval time of the short-time sound is 250ms, and personnel can obtain the fault type through statistics of the long-time sound times and the short-time sound times.

In addition, the following further explains the sound indication modes of two sound-emitting devices used in the invention, namely, motor sounding and buzzer sounding: the motor sound is only suitable for the ground, because the motor sound adopts a pulse signal with a specific frequency to the motor, so that the motor vibrates and sounds, which is not repeated for the concrete principle of the prior art. In flight, the frequency pulse signal can cause interference to the normal operation of the motor due to the operation of the motor. Therefore when using the motor as sound generating mechanism, microcontroller judges in advance whether unmanned aerial vehicle is in flight state through received state feedback signal, and when unmanned aerial vehicle was in flight state, microcontroller can not control driver output long-time high level signal and short time high level signal. And when using bee calling organ as sound generating mechanism, no matter whether unmanned aerial vehicle is in flight state, microcontroller is after reacing the fault type, all can control driver output long-time high level signal and short time high level signal, makes bee calling organ sound. Adopt bee calling organ also to conveniently fall down under the circumstances such as quick-witted, motor damage, personnel in time find back unmanned aerial vehicle according to calling out the sound.

In addition, in the present embodiment, the first interval time, the second interval time, the third interval time, the specific time, the long duration of the high level signal, the short duration of the high level signal, and the corresponding ratio are time-optimal solutions made by a large number of experiments in combination with the resolving power of eyes and ears.

The implementation principle of the intelligent fault indication method for the unmanned aerial vehicle power system in the embodiment of the application is as follows: the fault type is obtained by acquiring the state feedback signal and contrasting the fault indication table, and then corresponding light indication and sound chirping indication are made according to the fault type, so that the speed of judging the fault type by ground operators is greatly increased. The priority level is set, so that the personnel can conveniently judge the severity of the fault in time.

The embodiment of the application also discloses an intelligent fault indicating device of the unmanned aerial vehicle power system.
