The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention. The step numbers in the following embodiments are provided only for convenience of illustration, the order between the steps is not limited at all, and the execution order of each step in the embodiments can be adapted according to the understanding of those skilled in the art.
A helicopter data acquisition method, a system, an apparatus, and a storage medium according to embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and first, a helicopter data acquisition method according to embodiments of the present invention will be described with reference to the accompanying drawings.
Referring to fig. 1, a helicopter data acquisition method in an embodiment of the present invention mainly includes the following steps:
s1, determining grouping acquisition trigger events according to the monitoring component;
specifically, the group acquisition trigger event refers to a relatively stable operating state of the helicopter, and when the helicopter reaches the relatively stable operating state, the acquisition of monitoring data of each monitoring component of the helicopter is started.
The monitoring objects in this application are the three major moving parts of the helicopter, namely the rotor system, the transmission system and the engine, wherein the helicopter relies on the rotor system as the aircraft of the lift and steering mechanism, which rotor system corresponds to the wings, ailerons, elevators and propellers of a fixed wing aircraft. The transmission system is used as a power transmission component and is used for transmitting power provided by the engine to a rotor system and other components so as to drive the helicopter to fly. Therefore, the rotor system, the transmission system and the engine are three major moving parts of the helicopter, and the performance of the three major parts directly influences the performance and the reliability of the helicopter.
Each monitoring object comprises a plurality of monitoring components, for example, the monitoring components of the rotor system comprise a main rotor, a tail rotor and the like, the monitoring components of the transmission system comprise gears, shafts, bearings and the like, and the monitoring components of the engine are the engine per se.
According to the type of the monitoring component and the event trigger condition, firstly, the group acquisition trigger events are classified into a plurality of categories, in the embodiment, the categories of the group acquisition trigger events mainly include 5 categories of manual RTB (group acquisition trigger event category manually operated by a pilot), engine starting, rotor RTB (event category for performing group acquisition triggered by condition judgment through flight parameters), transmission system and engine stability, and secondly, each category of the group acquisition trigger events comprises a plurality of specific group acquisition trigger events, for example, the categories of the manual RTB group acquisition trigger events include a plurality of group acquisition trigger events such as pilot operation-ground, pilot operation-hovering, pilot operation-small speed level flight, pilot operation-large speed level flight and the like. The rotor RTB grouping acquisition trigger event category comprises a plurality of grouping acquisition trigger events such as ground small pitch, hovering, small-speed level flight, large-speed level flight and the like. The class of driveline group acquisition trigger events includes cruise and other group acquisition trigger events. Engine start includes engine start, etc. group acquisition trigger events. The engine stabilization includes a group acquisition trigger event such as engine start stabilization, where the group acquisition trigger event refers to the state of the engine reaching a steady state after a period of engine start.
S2, grouping the monitoring channels according to the monitoring components to obtain an acquisition group;
the sensor collects monitoring data on each monitoring part of a monitoring object, and transmits the collected monitoring data to the collector, namely a monitoring channel is formed. Each monitoring unit may have multiple types of sensors, and there may be multiple sensors of a certain type, for example, multiple vibration sensors, azimuth sensors, and rotor track sensors mounted on the main rotor for detecting the vibration, azimuth, and rotor track conditions on the main rotor, respectively, so that the monitoring channels of the main rotor include a main rotor vibration monitoring channel, a main rotor azimuth monitoring channel, a main rotor track monitoring channel, and the like.
Because the types and the rotating speeds of the monitoring components are different, the lengths of the monitoring channels and the collected monitoring data are determined to be different, so that the monitoring channels are grouped, and the required data length can be ensured to be collected according to the actual conditions of the monitoring components.
The monitoring channels are grouped, so that when a group acquisition triggering event occurs, data information of one or some monitoring components can be acquired in a targeted mode.
The grouping principle of the acquisition grouping comprises the following two points:
firstly, the monitoring channels for monitoring the monitoring components of the same type are classified into a group, and if the monitoring channels for monitoring the rotor wing are classified into a group, the monitoring channels for monitoring the engine are classified into a group according to table 1.
And secondly, grouping the monitoring channels of the monitoring components with the same or similar rotating speeds into a group. Referring to table 1, for example, the monitoring channels of the tail transmission shaft with the same rotating speed are grouped into one group; grouping the monitoring channels with similar rotating speeds of the transmission system and middle and tail reduction into a group; monitoring channels of accessory casings with similar rotating speeds in a transmission system are grouped, and the like.
Referring to table 1, each collection packet includes a packet name and a packet number.
Figure BDA0002705653910000051
TABLE 1
And S3, when a grouping collection triggering event occurs, collecting monitoring data by utilizing the collection grouping.
Specifically, since the helicopter has a long flight time, all monitoring channels continuously acquire monitoring data in the whole flight process, and after the flight is finished, a large amount of acquired monitoring data needs to be downloaded, decoded and analyzed, so that a CI curve capable of reflecting the health condition of the helicopter is obtained.
Based on the above reasons, the present application defines the grouping acquisition trigger event and the acquisition grouping, see table 1, and when one or some grouping acquisition trigger events occur, the corresponding acquisition grouping is triggered to acquire the monitoring data on the corresponding monitoring component, so that only the monitoring data in the stable operating state of the helicopter is acquired, the monitoring data in the unstable operating state is not acquired, the storage amount and the calculation amount of the monitoring data are reduced, and the operating efficiency is improved.
As a further optional implementation, a helicopter data acquisition method further includes the steps of:
and S4, processing the monitoring data.
Specifically, the time domain averaging algorithm can extract a specific frequency component from the complex component signal, thereby effectively improving the signal-to-noise ratio. Therefore, the monitoring data acquired by the acquired packets are preprocessed on the machine by adopting a time domain synchronous averaging algorithm, so that the stored data volume can be further reduced, and meanwhile, the calculation speed of the CI curve of the ground station and the data analysis efficiency are improved.
As a further optional implementation, a helicopter data acquisition method further includes the steps of:
and S5, determining the priority of the packet acquisition triggering event.
Specifically, each grouping acquisition trigger event triggers a corresponding acquisition grouping to acquire monitoring data, and when a plurality of grouping acquisition trigger events occur, data processing congestion is caused due to large data volume of the monitoring data acquired at the same time, and efficiency of data acquisition and data processing is reduced.
In a particular embodiment, the packet acquisition trigger event categories are prioritized by setting a first level priority, and the packet acquisition trigger events under each packet acquisition trigger event category are prioritized by setting a second level priority. For example, one level of priority may set manual TRB highest, the priority for engine start-up second, rotor RTB, drive train, engine stabilization may set continuous loop acquisition. When several group acquisition trigger events under a certain group acquisition trigger event category occur simultaneously, the priority level of the acquisition group trigger event corresponding to the acquisition group with the front group acquisition number can be set to be higher, and after the acquisition of the monitoring data of the acquisition group with the front group acquisition number is finished, the acquisition group with the back group acquisition number is executed to acquire the monitoring data.
In a certain group acquisition trigger event category, when the acquisition of the monitoring data of the acquisition group is being performed, if the working state of the helicopter changes (that is, the group acquisition trigger event changes), the behavior of acquiring the monitoring data of the acquisition group with the current priority will exit or be interrupted, then:
if the collection behavior of the current collection packet is interrupted by the type of the packet collection trigger event with high priority, the monitoring data collected by the current collection packet is discarded (because the cache needs to be emptied for storing the high-priority collection data);
if the current grouping collection is quitting (the working state of the helicopter does not meet the current grouping collection conditions, including not meeting the collection conditions of all the collection groups, meeting the collection conditions of the collection groups with low priority, or meeting the collection conditions of other collection groups with the same priority), the processing and the storage of the collected data of the current grouping are preferably finished;
when the original exit or interrupted packet acquisition trigger event is re-entered, acquisition of monitoring data should be performed sequentially starting from the last outstanding acquisition packet.
As a further optional implementation, a helicopter data acquisition method further includes the steps of:
and S6, determining the sampling frequency of the monitoring channel.
Specifically, among the prior art, the sampling frequency of the monitoring data of gathering the helicopter is lower, only several kilohertz, and all vibration channel's sampling frequency is the same, like this, only can monitor the rotor system of helicopter, the lower parts of rotational speed such as engine and transmission system's transmission shaft, the inside high-speed moving gear of transmission system, parts such as bearing, the monitoring data can not be gathered, consequently, this application sets up vibration channel's sampling frequency according to monitoring part's characteristic, thereby gather suitable monitoring data, do benefit to subsequent data analysis and processing.
In view of the above, the present application is directed to a specific monitoring component for which a specific and suitable sampling frequency is set. In a specific embodiment, according to the requirements of gear vibration monitoring and state index calculation, each tooth acquires data of 8 points at minimum, namely the minimum sampling frequency of a vibration channel of a monitoring gear is eight times of the gear meshing frequency; monitoring the vibration channel of the shaft according to a sampling theorem when the shaft monitoring frequency reaches 2-order rotation frequency, wherein the minimum sampling frequency rate is 2.56 times of the monitoring frequency; extracting bearing fault characteristic frequency by adopting a high-frequency demodulation algorithm in bearing vibration monitoring, wherein the minimum sampling frequency of vibration channel data of the monitored bearing is 102400 Hz; the rotor wing system monitors 2 times of rotor wing passing frequency, according to the sampling theorem, the sampling frequency meets the monitoring frequency of 2 times of rotor wing frequency, and the requirement that the precision of the dynamic balance phase is not more than 3 degrees when dynamic balance processing is carried out is compatible, namely the minimum sampling frequency is the maximum value of the two; the vibration channel for monitoring the engine meets the requirement of monitoring the rotating speed of a gas turbine, the rotating speed of a power turbine and an effective value of the engine, and the minimum sampling frequency is the maximum value of the three.
As a further optional implementation, a helicopter data acquisition method further includes the steps of:
and S7, determining the sampling time of the acquisition packet.
Specifically, different monitoring components determine the time for collecting the grouped monitoring data of the monitoring components, allocate proper collecting time for one collecting group, collect the monitoring data with proper data quantity, and solve the problems of excessive consumption of computing resources caused by overlarge data quantity and difficulty in reflecting the real condition of the helicopter due to small data quantity. In a specific embodiment, the acquisition time of the acquisition packet is:
the collecting time of the collecting groups of the rotor wing body, the gear and the shaft is the product of the time of one rotation of the rotating component and the number of rotations, the time of one rotation of the rotating component is the time of one rotation of the rotating component which rotates slowest in the collecting groups, the number of rotations is the number of time domain synchronous average turns, the time domain synchronous average needs to divide the vibration signal according to each rotation of the rotating component, then all the turns are added and averaged, and the total number of the collecting turns needing to be collected is the total number of turns obtained after the vibration signal is divided by a time domain synchronous average method, namely the number of the time domain synchronous average turns; according to the length required by analysis, determining the sampling time of the collection group of the bearing to be 2 s; the sampling time of the collection group of the engine starting is the time required by the whole starting process of the engine under the engine starting condition; the acquisition time of the engine-stable acquisition packet was 2s, according to the length required for the analysis.
Next, a helicopter data acquisition system proposed according to an embodiment of the present invention is described with reference to the drawings.
