And further preferably, the trigger logic parameter that the flight state parameter monitoring unit is configured to monitor in real time includes some or all of: longitude, latitude, altitude, brake status, cabin door status, international coordination time, landing gear system wheel load signal and oil consumption monitoring signal.
According to the remote measurement technology-based real-time monitoring solution for the aircraft pilot flight of the preferred embodiment of the invention, a whole set of clear and practicable architecture methods such as analysis of remote measurement data requirements, specific message formats, trigger logic definition, and CAPHM system analysis of ACARS messages can be achieved. Through the scheme, the aircraft data (from the telemetry data and realized by means of the existing telemetry system and network) in a specific format can be converted into ACARS message data, and the ACARS message data is used for monitoring the aircraft under the condition that the aircraft does not have a data link function in the early stage of the aircraft test flight.
According to a preferred embodiment of the invention, the aircraft safety monitoring system transmits the test flight telemetry data to the real-time monitoring and fault diagnosis system via serial port communication and ethernet.
According to a preferred embodiment of the invention, the data transmission between the aircraft safety monitoring system and the real-time monitoring and fault diagnosis system is based on the TCP/IP protocol.
According to a preferred embodiment of the present invention, the multiple types of ACARS messages include OUT message, OFF message, ON message, IN message, POS message, DOOR message, SLIDE message.
According to a preferred embodiment of the present invention, the ACARS message is an ARINC620 format message.
According to a preferred embodiment of the present invention, the flight test telemetry data adopts BUFR coding format, and the ACARS message formed by decoding by the aircraft safety monitoring system adopts TXT file format.
The method steps described in the above preferred embodiments regarding the predetermining of the multiple types of ACARS messages that need to be monitored in real time and determining the message content, message format and message trigger logic for each of the determined multiple types of ACARS messages are exemplified herein below.
In general, the method steps can be understood as determining trigger logic of a message in combination with a possible flight profile of a civil aircraft during flight, and in combination with aircraft monitoring experience, providing 6 ACARS message monitoring requirements for real-time monitoring during test flight of the civil aircraft, wherein the requirements include content, format and message trigger logic (definition of the messages) of the message to form a requirement definition for software development, and the flow and thought of the requirement definition are as follows:
1) Referring to a report form of the operation plane OOOI and a POS report form;
2) The parameters required for the test aircraft OOOI, POS messages are defined (refer to table 1 below).
3) Definition of civil aircraft report Wen Moban for software development (taking OUT report as an example, a template example is shown in fig. 2)
Table 1: parameters in examples of POS messages
The method steps in respect of the (telemetry) data transmission architecture and data conversion aspects involved in the method described in the above preferred embodiments can be generally understood as the solution being supported by each other mainly by the following three aspects of design to achieve data transmission and data conversion: 1) The flight test telemetry data are used for collecting real-time parameters of the aircraft and are used as data input sources; 2) The integrated processor (ASMS) triggers, for example, 7 different ARINC620 format messages (note: OUT (exit report), OFF (take-OFF report), ON (landing report), IN (push report), POS (position report), DOOR (DOOR report), SLIDE (SLIDE report)) to the ground system CAPHM; and the ground system (CAPHM) is used for analyzing the message from the integrated processor (ASMS) to realize the real-time monitoring of the pilot plane.
Because the flight test telemetry data generally resides in a dedicated server, and the CAPHM system (which may be a real-time monitoring and fault diagnosis system of a customer service company) is an external network system, software of an Aircraft Safety Monitoring System (ASMS) in the above scheme is designed to be capable of reading the telemetry server data in real time during the flight of an aircraft, converting the read data into a message in an ARINC620 format, for example, and finally analyzing the message by CAPHM to realize real-time monitoring. Such a data transmission architecture may be understood with reference to what is shown in fig. 1. "CAFTC" and "SACSC" shown in fig. 1 refer to commercial aircraft flight test center (Comac AIRCRAFT FLIGHT TEST CENTRE) and aircraft customer service center server (Server of aircraft customer SERVICE CENTRE), respectively.
Wherein the pilot data generally has high confidentiality requirements, and in order not to affect the collection of telemetry parameters of the aircraft, a mode of actively reading specific telemetry parameters by an aircraft safety monitoring system is adopted so as to prevent any adverse effect on the whole telemetry database. On the other hand, to facilitate the generation of ARINC620 format messages by an Aircraft Safety Monitoring System (ASMS) based on a software approach, engineering values may be first provided to the ASMS based on pilot telemetry data.
The conversion of telemetry data into ACARS messages can be designed to be mainly completed by ASMS software, wherein the ASMS software consists of 4 parts, and the ASMS software respectively resides in four computers to ensure the safety of data transmission. Taking the distance limitation of the test flight external field and the monitoring center into consideration, a part of ASMS resides in an external field test station to collect test flight telemetry data; the data is transmitted to a monitoring hall of a main manufacturer through a private network of the main manufacturer, so that the safety of data transmission is ensured; another part of the ASMS resides in the main manufacturer monitoring lobby and generates ACARS messages in ARINC620 format based on the collection of telemetry data and custom parameters and trigger logic.
Referring to FIG. 3, according to the Flight plan (Flight mission), engineers may manually preset parameters such as Aircraft Number, airline Number, flight Number, DEPART DATE, depart airport, etc. in the illustrated exemplary interface. The telemetry data is coded in BUFR format, and the coded data consists of an indication section, an identification section, a data description section, a data section and an end section. After the PC1 receives the telemetry flight data (Longitude, UTC, WOW, brain Status), the ASMS software grabs the data segment flight data according to BUFR coding format, integrating with preset parameters (e.g., as schematically shown in the right page of fig. 3). And finally, transmitting the message to a ground real-time monitoring and fault diagnosis system in a TXT file form through a TCP/IP protocol.

the real-time monitoring and fault diagnosis system is provided with a message analysis template in advance according to the message content and the message format of the multi-class ACARS message, and is configured to decode the test flight telemetry data with the message content contained in the ACARS message by adopting the message analysis template so as to convert the test flight telemetry data into the ACARS message.
According to a preferred embodiment of the invention, the aircraft safety monitoring system comprises a flight status parameter monitoring unit configured to monitor in real time the trigger logic parameter indicative of the aircraft status contained in the test flight telemetry data and to determine whether the value of the monitored trigger logic parameter meets the message trigger logic. Further preferably, the trigger logic parameter that the flight state parameter monitoring unit is configured to monitor in real time includes some or all of: longitude, latitude, altitude, brake status, cabin door status, international coordination time, landing gear system wheel load signal and oil consumption monitoring signal.
