Problems solved by technology

[0009] However, because the network communication interface protocols of the real star integrated test system software and the satellite simulator are different, the real star integrated test system software cannot directly receive the telemetry data sent by the satellite simulator in the control center mode
If a test system is redeveloped for the satellite simulator test alone, not only the workload is too large, but the correctness cannot be guaranteed

Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] First, the main steps of the universal conversion interface for satellite simulator telemetry are introduced in detail. It should be understood that the length of the telemetry data is fixed and the frame rate is fixed, so the processing of the telemetry data is relatively simple.

[0034] The main working steps of the general conversion interface of the satellite simulator are as follows:

[0035] (1) Read the configuration file and establish a network connection;

[0036] (2) The receiving thread monitors the network, and if telemetry data is received, step (3);

[0037] (3) Convert the received telemetry data into a unified internal format, and store it in the data buffer area, and notify the forwarding thread that there is new telemetry data, and then detect whether there is telemetry data in the received network data packet agai...

Abstract

The invention provides a telemetry data conversion method. The method comprises the following steps: reading a configuration file of a general conversion interface and establishing network connection; monitoring a network through a receiving thread to receive telemetry data; converting the received telemetry data into a uniform format, and storing the converted telemetry data in a data cache region; and after receiving a notification of the receiving thread, reading the converted telemetry data from the data cache region through a transmitting thread, and transmitting the read telemetry data to true star comprehensive testing system software. Through application of the true star comprehensive testing system software to the testing of satellite simulators, the building speed of a testing system is increased, and the correctness of the testing system is ensured. Since the true star comprehensive testing system software is applied to the testing of satellite simulators of various models, the universality of the conversion interface is fully proven. Moreover, testing is performed during 18-time-speed and 16-time-speed simulation of the satellite simulators, so that the working stability is high, and data forwarding is normal. Moreover, real-time display is available, so that the network communication situation and the telemetry situation transmitted by the satellite simulators can be observed conveniently.

Description

technical field [0001] The invention relates to the field of network data format conversion, and more specifically, relates to a method for converting the telemetry network data format between real star comprehensive test system software and a satellite simulator. Background technique [0002] It should be understood that the satellite simulator is a supporting product of the satellite project, and mainly completes the following tasks: [0003] 1. Carry out a comprehensive inspection of the working status of the telemetry reception and remote control command transmission of the ground measurement and control center; [0004] 2. In the simulated environment, train the operation and command personnel so that they are familiar with the flight procedures of the satellite and master the operation and handling of important events before the satellite launch, so as to reduce the risks in the execution of the mission; [0005] 3. Carry out drills before carrying out satellite measu...
