14 Electrical Testing Technology of Lunar Lander
were established in integrated test. All kinds of test data could be accessed and
acquired by subsystem software, which made it easy to analyze test data.
14.5.3 Configuration of Ground Test System
The ground test system was distributed local network system with two levels management. The OCOE was connected with special checkout equipment (SCOE) of
subsystem via Ethernet. Graphic data display terminals were configured to monitor
test data. Test data interpretation terminals were configured, and test database
provided database storage service to all subsystems. The configuration of ground
test system of the Chang’E-3 lunar lander is shown in Fig. 14.5.
The OCOE was the management center of test process for data processing,
control command management, automatic test implementation, analysis of test data,
command and control. It could implement the remote control of front-end equipment of power supply and distribution subsystem, TT&C and telecommunication
subsystem, the reception, processing and display of telemetry and data transmission
data, the generation of telecommand and data injection, and the support for storage,
query and interpretation service of test data.
There were 5 types of SCOE as follows.
(1) Test equipment of power supply and distribution subsystem: to implement
ground power supply, wired command sending and wired parameter acquisition
for the Lander.
