Usually, a generator is installed around the radar to realize on-site power supply for the ground-based synthetic aperture radar.

[0004] However, since the radar needs to run continuously for a long time during measurement, the generator supplying power to the radar also needs to run for a long time. Therefore, the staff needs to supplement fuel to the generator at irregular times to maintain its power supply work to the radar, thereby increasing the work difficulty of the staff, and a large amount of energy consumption is generated due to the burning of fuel.

[0016] The present application will be further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, but not all the structures.

[0017] Figure 1 is a structural schematic diagram of the radar power supply device provided by the present application, as shown in Figure 1 the radar power supply device provided by the present application comprises a solar power supply module, a commercial power supply module and a power supply control module.

[0018] The solar power supply module is connected with the power supply control module and the target radar, and the commercial power supply module is connected with the power supply control module and the target radar.

[0019] The solar power supply module comprises a solar panel and an energy storage battery, the solar panel is connected with the first end of the energy storage battery, the second end of the energy storage battery is connected with the power supply control module, the third end of the energy storage battery is connected with the target radar, the solar panel is used to charge the energy storage battery, and the energy storage battery is used to supply power to the target radar.

[0020] The power supply control module is used to output a first indication signal to the commercial power supply module when the discharging efficiency of the energy storage battery is greater than the charging efficiency, and the electric quantity of the energy storage battery is less than a first preset electric quantity.

[0021] The commercial power supply module is used to supply power to the target radar when the first indication signal is received.

[0022] Specifically, the target radar is a radar to be powered, which can be a ground-based synthetic aperture radar. The solar power supply module is a module that supplies power to the radar by collecting solar energy. The commercial power supply module is a module that supplies power to the radar by commercial power. The power supply control module is a module that outputs different indication signals when different trigger conditions are detected, and the indication signals are used to indicate the operation of other power supply modules. For example, the power supply control module can be a programmable logic controller (PLC) with pre-set trigger conditions and corresponding output indication signals. The solar power supply module includes a solar panel and an energy storage battery. The solar panel is used to collect solar energy and charge the energy storage battery. For example, the number of solar panels can be 4, and the maximum output power of the solar panels can be 150 watts. The energy storage battery can be charged and discharged, that is, the energy storage battery can be charged by the solar panel and can supply power to the target radar.

[0023] The first preset power is a preset power that can represent that the power of the energy storage battery is slightly insufficient. For example, the first preset power can be 50% of the full power of the energy storage battery. When the power supply control module detects that the discharge efficiency of the energy storage battery is greater than the charging efficiency and the power of the energy storage battery is less than the first preset power, it means that the single power supply mode of the solar power supply module is insufficient to meet the power consumption of the radar. For example, when the weather is gloomy and there is not enough sunlight, the power supply control module outputs a first indication signal representing the working instruction of the commercial power supply module to the commercial power supply module. When the commercial power supply module receives the first indication signal, it supplies power to the target radar to ensure sufficient power consumption of the radar and avoid the situation that the radar is powered off when the solar charging module cannot meet the power supply demand of the radar, thereby improving the stability of the radar power supply device.

[0024] Optionally, the radar power supply device further comprises a motor power supply module.

[0025] The motor power supply module is connected with the power supply control module and the target radar.

[0026] The power supply control module is further configured to output a second indication signal to the motor power supply module when the discharge efficiency of the energy storage battery is greater than the charging efficiency and the power of the energy storage battery is less than or equal to a second preset power. The second preset power is less than the first preset power.

[0027] The motor power supply module is configured to supply power to the target radar when receiving the second indication signal.

[0028] Specifically, the second preset electric quantity is a preset electric quantity capable of representing that the electric quantity of the energy storage battery is insufficient. For example, the second preset electric quantity can be 30% of the full electric quantity of the energy storage battery. The motor power supply module is a module for supplying power to the radar using a generator. When the power supply control module detects that the discharging efficiency of the energy storage battery is greater than the charging efficiency and the electric quantity of the energy storage battery is less than or equal to the second preset electric quantity, it is indicated that the combined power supply mode of the solar power supply module and the commercial power supply module is insufficient to meet the power consumption of the radar. At this time, the power supply control module outputs a second indication signal capable of representing a working instruction of the motor power supply module to the motor power supply module. The motor power supply module is used to supply power to the target radar when the second indication signal is received, thereby further improving the stability of the radar power supply device.

[0029] Figure 2 is an exemplary structural schematic diagram of the radar power supply device provided by the present application. As shown in Figure 2 , the solar cell panel is connected with the first end of the energy storage battery, the second end of the energy storage battery is connected with the power supply control module, and the third end of the energy storage battery is connected with the target radar. The commercial power supply module is connected with the power supply control module and the target radar. The motor power supply module is connected with the power supply control module and the target radar.

[0030] Figure 3 is another exemplary structural schematic diagram of the radar power supply device provided by the present application. As shown in Figure 3 , the solar power supply module includes a solar cell panel, an energy storage battery, and a first relay. The first end of the first relay is connected with the solar cell panel, the second end of the first relay is connected with the first end of the energy storage battery, and the third end of the first relay is connected with the power supply control module. The second end of the energy storage battery is connected with the power supply control module, and the third end of the energy storage battery is connected with the target radar. The commercial power supply module includes a commercial power supply device and a second relay. The first end of the second relay is connected with the commercial power supply device, the second end of the second relay is connected with the target radar, and the third end of the second relay is connected with the power supply control module. The motor power supply module includes a motor power supply device and a third relay. One end of the third relay is connected with the first end of the motor power supply device, the second end of the third relay is connected with the target radar, and the third end of the third relay is connected with the power supply control module.

[0031] Optionally, the solar power supply module further includes a first relay. The first end of the first relay is connected with the solar cell panel, the second end of the first relay is connected with the first end of the energy storage battery, and the third end of the first relay is connected with the power supply control module.

[0032] The power supply control module is further used to output a third indication signal to the first relay when the power supply voltage of the solar cell panel is greater than a preset safety voltage.

[0033] The first relay is configured to connect the solar panel and the energy storage battery when the third indication signal is not received.

[0034] The first relay is further configured to disconnect the solar panel and the energy storage battery when the third indication signal is received.

[0035] Specifically, when the solar panel supplies power to the energy storage battery, the first relay is in a closed state, i.e., the first relay connects the solar panel and the energy storage battery when the third indication signal is not received. The preset safety voltage is a pre-set safety voltage threshold. When the power supply voltage of the solar panel is greater than the preset safety voltage, the continuous power supply of the solar panel to the energy storage battery will cause damage to the energy storage battery. Therefore, the power supply control module is further configured to output the third indication signal to the first relay when the power supply voltage of the solar panel is greater than the preset safety voltage, and the first relay disconnects the solar panel and the energy storage battery when the third indication signal is received, so as to protect the energy storage battery and the solar panel, and increase the safety performance of the radar power supply device.

[0036] Optionally, the commercial power supply module includes a commercial power supply device and a second relay, a first end of the second relay is connected with the commercial power supply device, a second end of the second relay is connected with the target radar, and a third end of the second relay is connected with the power supply control module.

[0037] The power supply control module is configured to output a first indication signal to the second relay.

[0038] The second relay is configured to disconnect the commercial power supply device and the energy storage battery when the first indication signal is not received.

[0039] The second relay is further configured to connect the commercial power supply device and the target radar when the first indication signal is received.

[0040] The power supply control module is further configured to output a fourth indication signal to the second relay when the discharge efficiency of the energy storage battery is less than the charging efficiency, and the energy storage battery has an energy amount greater than or equal to a first preset energy amount.

[0041] The second relay is further configured to disconnect the commercial power supply device and the energy storage battery when the fourth indication signal is received.

[0042] Specifically, the commercial power supply device can be a plug connected with the commercial power supply, and the commercial power supply device is connected with the target radar through the second relay. The power supply control module outputs a first indication signal to the second relay when it is determined that the effect of the single solar power supply module supplying power to the radar is insufficient to meet the power supply demand of the radar, i.e., the discharging efficiency of the energy storage battery is greater than the charging efficiency, and the power of the energy storage battery is less than the first preset power. The second relay is in an open state when it does not receive the first indication signal. When the second relay receives the first indication signal, the commercial power supply device and the target radar are connected to complete the process of the commercial power supply module supplying power to the target radar. When the discharging efficiency of the energy storage battery is less than the charging efficiency, and the power of the energy storage battery is greater than or equal to the first preset power, it indicates that the solar power supply module can meet the power supply demand of the target radar, and the commercial power supply module is no longer needed to supply power to the target radar. Therefore, when the discharging efficiency of the energy storage battery is less than the charging efficiency, and the power of the energy storage battery is greater than or equal to the first preset power, the power supply control module outputs a fourth indication signal to the second relay, and the second relay is further configured to disconnect when receiving the fourth indication signal, thereby disconnecting the connection between the commercial power supply device and the energy storage battery. Thus, the process of cutting off the commercial power supply device from supplying power to the target radar is realized, and the energy-saving effect of the radar power supply device is further improved.

[0043] Optionally, the motor power supply module includes a motor power supply device and a third relay, one end of the third relay is connected with a first end of the motor power supply device, a second end of the third relay is connected with the target radar, and a third end of the third relay is connected with the power supply control module.

[0044] The power supply control module is configured to output a second indication signal to the third relay.

[0045] The third relay is configured to connect the motor power supply device and the target radar when receiving the second indication signal.

[0046] The power supply control module is further configured to output a fifth indication signal to the third relay when the discharging efficiency of the energy storage battery is less than the charging efficiency, and the power of the energy storage battery is greater than a second preset power.

[0047] The third relay is further configured to disconnect the connection between the motor power supply device and the target radar when receiving the fifth indication signal.

[0048] Specifically, the motor power supply device is a device capable of generating electricity, such as a generator, and the motor power supply module is connected to the target radar through a third relay. When the solar power supply module and the mains power supply module are determined to be insufficient to meet the power supply requirements of the radar, that is, the power of the energy storage battery is less than or equal to the second preset power, the motor power supply module outputs a second indication signal to the third relay. The third relay is in an open state when it does not receive the second indication signal. When the third relay receives the second indication signal, it connects the motor power supply device and the target radar to complete the process of the motor power supply module supplying power to the target radar. When the discharge efficiency of the energy storage battery is less than the charging efficiency, and the power of the energy storage battery is greater than the second preset power, it indicates that the combined power supply of the solar power supply module and the mains power supply module to the radar can meet the power supply requirements of the target radar, and the motor power supply module is no longer needed to supply power to the target radar. Therefore, when the discharge efficiency of the energy storage battery is less than the charging efficiency, and the power of the energy storage battery is greater than the second preset power, the power supply control module outputs a fifth indication signal to the third relay, and the third relay is further configured to disconnect when receiving the fifth indication signal, thereby disconnecting the connection between the motor power supply device and the energy storage battery. Thus, the process of cutting off the power supply of the motor power supply device to the target radar is realized, further improving the energy-saving effect of the radar power supply device.
