Embodiments of the present invention will be described below with reference to the accompanying drawings.
An embodiment of the present invention provides a method for processing telemetry data, as shown in fig. 1, the method includes the following steps:
and S101, acquiring telemetry data of the telemetry system in real time.
Optionally, the real-time acquisition of telemetry data of the telemetry system comprises:
and when the byte length of the received telemetry data is greater than or equal to a preset first byte length, intercepting the data with the preset first byte length as data to be processed.
In practical application, the telemetering data sent by the telemetering system is generally continuously sent to an upper computer as a packet of telemetering data according to a preset byte length, and the upper computer processes the telemetering data. Telemetry systems typically transmit UDP (user datagram Protocol) data. The byte length of each packet of telemetry data may be a preset first byte length, and if the byte length of the received telemetry data is greater than or equal to the preset first byte length, the indication indicates that at least one packet of telemetry data has been received, and the packet of telemetry data is intercepted according to the preset first byte length. The telemetering data is data encoded based on Pulse Code Modulation (PCM), and the telemetering data is sequentially spliced according to a receiving sequence and cached in a database of an upper computer, wherein the upper computer can be a computer, a notebook computer or other terminal equipment capable of operating a telemetering data processing method.
The UDP protocol is a connectionless transport layer protocol in the OSI (Open System Interconnection) reference model, and provides a transaction-oriented simple unreliable information transfer service, and IETF RFC 768 is a formal specification of UDP, and a common interface form is RJ 45.
PCM is one of the encoding methods of digital communication, and is mainly performed by sampling analog signals such as voice and image at regular intervals to discretize the analog signals, rounding down the sampled values in hierarchical units to perform rounding quantization, and expressing the sampled values in a set of binary codes as the amplitude of sampled pulses. The PCM coding format may comprise a plurality of data formats such as analog quantity and digital quantity, and the transmission may be compatible with a plurality of code rates.
S102, extracting first effective data in the telemetering data according to a preset first zone bit; the telemetry data includes at least two first flag bits.
Optionally, the first flag bit is a preset frame header, and the data is intercepted according to the preset frame header of the telemetry data.
And S103, processing the first effective data to obtain data information.
In practical application, the data information includes the data of the missile or rocket operation conditions such as longitude, latitude, altitude, course angle, roll angle, pitch angle, angular velocity and acceleration.
As an example, when the first byte length is 1008 bytes, and the length of the received UDP data is greater than or equal to 1008 bytes, the 1008 bytes of UDP data is intercepted as the data to be processed. And the telemetering data and the data to be processed are cached in the database according to the receiving sequence.
The embodiment of the invention extracts the effective data for processing while receiving the telemetric data, thereby obtaining real-time data information and timely obtaining the required data information, avoiding the problems of long data processing time and long interpretation time caused by centralized and simultaneous processing of a large amount of telemetric data after receiving the telemetric data for a period of time, and further improving the data processing efficiency.
Optionally, referring to fig. 2, as an example, the processing method of the telemetry data processing method includes the following steps:
s201, acquiring telemetering data of a telemetering system in real time, and intercepting the data with the preset first byte length as data to be processed when the byte length of the received telemetering data is larger than or equal to the preset first byte length.
Furthermore, the data to be processed is a process of continuously intercepting the data to be processed with the first byte length in the process of continuously receiving the telemetering data, then storing each section of the intercepted data to be processed in the database, and continuously processing the previous data to be processed according to the receiving sequence.
S202, starting from a first flag bit in the data to be processed, sequentially judging whether the interval length between two adjacent first flag bits is a preset second byte length.
S203, if the interval length between two adjacent first zone bits is the preset second byte length, extracting data between the two adjacent first zone bits as first effective data; caching the first valid data in a database according to a receiving sequence;
and S204, if the interval length between two adjacent first flag bits is not the preset second byte length, deleting the first flag bit at the front of the two adjacent first flag bits, splicing the next section of data to be processed, and continuing the process of judging whether the interval length between the two adjacent first flag bits is the preset second byte length in the step S202.
And S205, processing the first effective data to obtain data information.
Further, step S203 and step S204 are two cases of step S202, in step S203, the first valid data is cached in the database according to the receiving sequence, so that when the first valid data is subsequently processed, the first valid data can be processed according to the receiving sequence, and the obtained data information is prevented from being inconsistent with the data received in real time. Meanwhile, the extracted multiple sections of first effective data can be spliced in sequence in the database, or splicing is not needed. And while the first effective data is extracted and cached, the first effective data is continuously analyzed and processed to obtain data information.
As an example, the preset second byte length is 508 bytes, the first flag bit is a preset first frame header, whether 508 bytes are left between two adjacent first frame headers is sequentially judged from the first frame header, if the space length is 508 bytes, the extracted first valid data is valid, the former one of the two adjacent first frame headers is deleted, and then the subsequent data to be processed is continuously and sequentially processed; if the interval length is not 508 bytes, the extracted first effective data is wrong, the first frame header which is positioned at the front of the two adjacent first frame headers is deleted, the upper section of data to be processed and the lower section of data to be processed are spliced according to the receiving sequence, the newly formed data is matched with the two adjacent first frame headers again from the first frame header, and whether the interval between the two adjacent first frame headers is 508 bytes is continuously and sequentially judged.

And S303, analyzing the target data based on the communication protocol corresponding to each type of data to be processed to obtain data information.
Based on the embodiment shown in fig. 3, the embodiment of the present invention can classify the data according to the data type to form at least one type of valid data to be processed, and then process each type of valid data to be processed, so as to obtain the data information. The embodiment of the invention can meet the requirement of generalization of telemetry data analysis, realize the processing of the telemetry data with multiple data types or complex data types, and further adapt to the data processing of various telemetry systems.
Optionally, after step S301 and before step S302, the method further includes:
and correspondingly deleting the filling data in each type of effective data to be processed according to the preset filling data corresponding to each type of data.
In the process of data transmission, as the telemetering data is transmitted one packet by one packet according to the preset byte length, the speed of filling data with data information into each packet of telemetering data is generally lower than the transmission speed of each packet of telemetering data, each packet of telemetering data is sent out after being filled with corresponding preset filling data, the filling data is invalid data, and the data needs to be deleted when data analysis is carried out. The embodiment of the invention correspondingly deletes the filling data in each type of effective data to be processed, thereby being suitable for the conditions of various channel storage capacities and various code rates. The code rate is a data transmission rate, and has a unit of bit/s (bit/second), and represents the propagation capacity of a digital signal in a certain time.

RS485, a serial data transmission protocol of half-duplex, differential transmission and multipoint communication. RS232 is a full-duplex, common level transport, serial data transfer protocol commonly used for single-point communications.
Optionally, in step S302, when the type of the valid data to be processed is CAN data, starting from a first preset CAN zone bit in the type of the valid data to be processed, it is sequentially determined whether an interval length between two adjacent CAN zone bits is a preset fourth byte length.
And if the interval length between two adjacent CAN zone bits is the preset fourth byte length, extracting the data between the two adjacent CAN zone bits as the target data of the data.

The specific method in this step is the same as the specific method in step S301, and is not described herein again.
And S502, correspondingly deleting the filling data in each type of effective data to be processed according to the preset filling data corresponding to each type of data.
