The invention discloses an autonomous dormancy and wake-up system for a Mars rover. The autonomous dormancy and wake-up system comprises a solar cell, a power supply relay, an MPPT circuit, a wake-up relay, a temperature relay, a wake-up relay coil, a wake-up resistor, a Mars rover load and a PCU power supply, wherein the solar cell is connected with a common end of the power supply relay; the PCU power supply, the wake-up relay coil and the wake-up resistor are arranged in parallel to form a wake-up circuit; the PCU power supply is connected in series with the wake-up relay and then connected to a B end of the power supply relay; one end of the wake-up relay coil is grounded after being connected in series with the temperature relay, and the other end is connected to the B end of the power supply relay; one end of the wake-up resistor is grounded, and the other end is connected to the B end of the power supply relay; the Mars rover load and the MPPT circuit are connected in series and then connected to an A end of the power supply relay to form a normal power supply circuit. According to the dormancy and wake-up system, autonomous dormancy and wake-up of the Mars rover are realized, so adaptive Mars weather environment and communication constraints are formed.

    本发明公开了一种火星车自主休眠与唤醒系统,包括:太阳电池、供电继电器、MPPT电路、唤醒继电器、温度继电器、唤醒继电器线包、唤醒电阻、火星车负载和PCU电源;太阳电池与供电继电器的公共端连接;PCU电源、唤醒继电器线包与唤醒电阻并联设置,构成唤醒电路;其中,PCU电源串联唤醒继电器后接入供电继电器的B端;唤醒继电器线包的一端串联温度继电器后接地,另一端接入供电继电器的B端;唤醒电阻的一端接地,另一端接入供电继电器的B端;火星车负载与MPPT电路串联后接入供电继电器的A端,构成正常供电电路。本发明实现了火星车的自主休眠与唤醒,以使或形成适应火星天气环境和通信约束。
