The solar power supply module is used for supplying power to the vehicle-mounted unit when the vehicle-mounted unit is in a dormant state. And the main battery power supply module is used for supplying power to the vehicle-mounted unit when the vehicle-mounted unit is in an awakening state.
The power supply system of the vehicle-mounted unit provided by the embodiment of the invention comprises a solar power supply module, a main battery power supply module, and the solar power supply module and the main battery power supply module of the vehicle-mounted unit are connected with the vehicle-mounted unit. The solar power supply module is used for supplying power to the vehicle-mounted unit when the vehicle-mounted unit is in a dormant state. And the main battery power supply module is used for supplying power to the vehicle-mounted unit when the vehicle-mounted unit is in an awakening state. In the embodiment of the invention, the solar power supply module is used for providing electric energy preferentially when the vehicle-mounted unit is in the dormant state, and the electric energy required by the vehicle-mounted unit in the dormant state is small, so that the energy storage element is not required to have high electric capacity, the capacity requirement on the energy storage element is low, and the hardware cost can be effectively reduced.
Optionally, the solar power supply module includes a solar cell, a first diode, an energy storage element, a voltage stabilizing unit, and a second diode; the solar cell is connected with the anode of the first diode; the cathode of the first diode is connected with one end of the energy storage element; the other end of the energy storage element is connected with one end of the voltage stabilizing unit; the other end of the voltage stabilizing unit is connected with the anode of the second diode; the cathode of the second diode is connected with the vehicle-mounted unit; the solar cell is used for charging the energy storage element; the first diode is used for unidirectionally inputting the current output by the solar cell to the energy storage element; the energy storage element is used for providing electric energy for the vehicle-mounted unit; the voltage stabilizing unit is used for inputting the electric energy provided by the energy storage unit to the vehicle-mounted unit when the vehicle-mounted unit is in a dormant state; and the second diode is used for unidirectionally inputting the electric energy output by the voltage stabilizing unit into the vehicle-mounted unit.
In a possible implementation manner, the voltage stabilizing unit is further configured to receive a first control signal sent by the on-board unit, and output electric energy to the on-board unit under the control of the first control signal; the first control signal is sent by the vehicle-mounted unit in a dormant state.
The voltage stabilizing unit can be controlled by the cooperation of the wake-up circuit and the logic control circuit of the OBU.
Optionally, the main battery power supply module includes a disposable battery, a third diode, and a switching element; the disposable battery is connected with the anode of the third diode; the cathode of the third diode is connected with the vehicle-mounted unit; the switching element is connected in parallel with the third diode; the disposable battery is used for providing electric energy for the vehicle-mounted unit; the third diode is used for unidirectionally inputting the electric energy output by the disposable battery into the vehicle-mounted unit; the switching element is used for being closed when the vehicle-mounted unit is in a wake-up state and being opened when the vehicle-mounted unit is in a sleep state.
The disposable battery may be a lithium manganese battery (Li-MnO 2). The Li-MnO2 battery has the characteristics of excellent discharge characteristic and no passivation, and can overcome the defects of the lithium thionyl chloride battery.
In a possible implementation manner, the switching element is further configured to receive a second control signal sent by the on-board unit, and is switched from an open state to a closed state under the control of the second control signal; the second control signal is sent by the on-board unit in an awake state.
The switching element may be a P-channel Metal Oxide Semiconductor field effect transistor (PMOS). The switching element can be controlled by the wake-up circuit and the logic control circuit of the OBU in a coordinated manner.
The control logics of the switching element and the voltage stabilizing unit are opposite, i.e. the first control signal is opposite to the second control signal, so that the switching element and the voltage stabilizing unit are in an alternately switched state.
The energy storage element accumulates electric energy from the solar cell, and the voltage does not exceed 6V. When the OBU is in a dormant state, the OBU sends a first control signal to the voltage stabilizing unit, the voltage stabilizing unit enables, the switch element is switched to an off state, the output voltage of the voltage stabilizing unit is 3.6V, standby current is provided for the OBU through a second diode (the voltage drop is about 0.2V), the switch element is in the off state at the moment, the disposable battery (the voltage is below 3.2V) outputs voltage through a third diode (the voltage drop is about 0.2V), it can be seen that the voltage output by the main battery power supply module is smaller than the voltage output by the solar power supply module, and therefore the standby current of the OBU is mainly provided by the solar power supply module.
When the electric energy of the solar power supply module is insufficient, namely the output voltage of the solar power supply module is smaller than the voltage output by the main battery power supply module, the standby current of the OBU is mainly provided by the main battery power supply module. When the OBU is awakened, the OBU sends a second control signal to the switching element, and the switching element is switched to a closed state, so that the voltage stabilizing unit is turned off. At this time, the solar power supply module stops supplying power to the OBU, and the disposable battery outputs electric energy through the switching element in the closed state, so that the voltage of the disposable battery is output to the OBU with almost no attenuation, and the OBU is supplied with power by the main battery power supply module at this time. When the OBU returns to the dormant state, the control logic of the OBU is switched to the first control signal again, so that the OBU is preferentially powered by the solar power supply module in the standby state. In addition to the solar cell and the disposable battery, other circuit parts can be designed on the same PCB as the power supply module of the OBU.
In the embodiment of the invention, the main battery power supply module and the solar power supply module are combined together in a circuit structure by adopting double diodes (a second diode and a third diode), so that the OBU can be preferentially powered by the solar battery in a standby state and can be automatically switched to be powered by a disposable battery when the power supply of the solar battery is insufficient. Because the OBU is powered by the solar battery only in the dormant state, the energy storage element does not need large capacity requirement, and the disposable battery has strong discharge capacity and does not need the energy storage element with large capacity connected in parallel, thereby effectively reducing the hardware cost. In addition, through the parallelly connected switching element in third diode both ends between disposable battery and OBU for when the OBU awaken up the back, the electric energy of disposable battery output can pass through switching element output, has avoided the voltage attenuation that the third diode leads to, makes the voltage of disposable battery can be almost lossless applyed in the OBU, thereby has improved the utilization ratio of battery power.
