[0138] The verification method provided by the present invention is illustrated with examples.
[0139] Step 1. Initialize file configuration;
[0140] The ground monitoring and fault injection computer 3 configures the initial file configuration of the temperature control system. The RT-RT hot backup mode is selected here. The temperature setting in the cabin is 19-25 degrees Celsius on the sunny side and 23-30 degrees Celsius on the backside, and the setting is 100. Heater 1 fault occurs in seconds, and sensor 1 data offset fault occurs in the 105th second. After generating the configuration file, wait for the on-board temperature control system 2 computer to connect and extract.
[0141] Step two, system initialization;
[0142] After the main and standby machines of the on-board temperature control system 2 are started, they connect and log in to the ground monitoring and fault injection computer 3 in the form of clients respectively, obtain configuration files, initializ...
