Problems solved by technology
If it is installed on an uninhabited island, it is difficult to supply power. The traditional method is to set up a submarine power supply cable to provide power, which is very costly. However, this method of power supply also has a disadvantage. Once there is no wind and no light, it has to rely on battery power supply. Over time, the battery power supply capacity is limited, and the radar data will be interrupted.

The invention relates to the technical field of radar detection, in particular to a device for automatically switching the working mode of a ground wave radar. The device is characterized by comprising a storage battery detection circuit (1), a comparing and judging circuit (2), a 16-digit counter circuit (3), a driving gate circuit (4), a frame synchronizing pulse extracting circuit (5), a rectifying circuit (6) and a control gate circuit (7). In the device for automatically switching the working mode of the ground wave radar, the working time of the radar can be prolonged by certain hours in absence of wind and light by using a wind-light complementary power supply system after a system is switched to a power-saving mode, so that the investment cost of a radar system can be lowered, the size of the wind-light complementary power supply system is reduced, and the stability and reliability of the system are improved.
Description
technical field [0001] The invention relates to the technical field of radar detection, in particular to an automatic switching device for ground wave radar working modes powered by solar energy and wind energy. Background technique [0002] The basic components of a radar system are transmitter, receiver, antenna and signal processing system. The OSMAR-S portable high-frequency ground wave radar system is mainly used to measure state parameters such as ocean currents, sea winds, and waves on the ocean surface. It can refresh the measurement data record once every 6 minutes. It can be installed on land or in unmanned vehicles. On the island, the energy consumption of the radar system is about 600 watts. If it is installed on an uninhabited island, it is difficult to supply power. The traditional method is to set up a submarine power supply cable to provide power, which is very costly. However, this method of power supply also has a disadvantage. Once there is no wind and n...
