Internal battery relay status display device and status display method for satellite testing {SATELLITE TEST INTERNAL BATTERY RELAY STATUS DISPLAY DEVICE AND STATUS DISPLAY METHOD}

The present invention relates to an internal battery relay status display device and status display method for satellite testing that allows the status of the battery inside the satellite to be easily recognized through a light emitting device or digital multimeter in the electrical assembly test of the satellite. It's about.

The final stage of satellite development is the process of assembling the components (hardware and software) of the designed/manufactured satellite and verifying performance and functions through testing.

The final stage of satellite development can be divided into mechanical assembly testing and electrical assembly testing.

Mechanical assembly testing and electrical assembly testing have many potential risks.

For example, in the case of a mechanical assembly test, there is a risk of damaging the satellite by operating the mechanical ground support equipment while the bolts that secure the satellite to the mechanical ground support equipment are not fastened.

In the case of an electrical assembly test, the lifespan of the battery, which is a component of the satellite, is shortened by terminating the test without knowing whether battery power is continuing to be supplied to the satellite, or the lifespan of the battery, which is a component of the satellite, is shortened, or the battery power is supplied to the satellite, There is a risk that test participants may be at risk and component failure may occur due to connection of cables, etc.

Since the ground test of the electrical assembly test cannot be conducted using solar panels, which are the satellite's largest power source, it is performed using electrical ground support equipment that simulates solar panels.

When using electric ground support equipment, a battery is essential because the power of the electric ground support equipment is generated based on the voltage of the battery.

Figure 1 is a power supply schematic diagram for electrical assembly testing of an existing satellite.

Figure 1 shows the power-related shape of a typical satellite.

Battery power is supplied to the satellite power supply and control electronics through the ground test battery relay module 102 and the battery connection relay 105, and is distributed to each satellite component 109 through the power distribution relay 108.

In the satellite electrical assembly test, when operating the satellite without using the battery 103, power is supplied from the External Power Supply Equipment 101 and directly to the power bus bar 107, as shown in FIG. 1. Apply to operate the satellite.

However, when power is supplied through the external power supply line (a), a small amount of power can be supplied that can only power the satellite computer or basic electronic equipment.

In order to check all functions of the satellite, the solar panel power simulation electric ground support equipment 104, which has a large power supply function that can operate all of the satellite components 109 in FIG. 1, is used.

In order to use the solar panel power simulation electric ground support equipment (104), the battery (103) must be connected.

In a conventional satellite electrical assembly test, even if the battery 103 inside the satellite was connected, the connection status of the battery 103 could not be known before the satellite computer was turned on.

As a result, in the past, power line-related work was performed while the battery 103 was continuously discharged or the battery 103 was connected to the power bus bar 107, causing problems with the safety of workers such as test participants or satellite There has always been a problem with electrical equipment malfunctioning.

Therefore, in electrical assembly testing of satellites, a new model that allows easy recognition of the state of the battery inside the satellite is urgently needed.
