[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] like Figure 1-2 As shown, this utility model provides a weather radar early warning system, including a mobile detection vehicle 1 and a remote monitoring center 2. The mobile detection vehicle 1 includes a vehicle body, and a weather radar 3, an atmospheric electric field instrument 4, and a lightning locator 5 are installed on the vehicle body's compartment. A data acquisition card 6 is installed inside the vehicle compartment. The weather radar 3, atmospheric electric field instrument 4, and lightning locator 5 are all electrically connected to the data acquisition card 6. The data acquisition card 6 includes a DSP processor, a conditioning circuit, an AD converter, a power module, and an interface module. The conditioning circuit is connected to the AD converter, and the AD converter, power module, and interface module are all connected to the DSP processor. A host computer 7 is also installed inside the vehicle compartment. The data acquisition card 6 is connected to the host computer 7 through the interface module. The host computer 7 has a wireless communication unit, and the host computer 7 is connected to the remote monitoring center 2 through the wireless communication unit.

[0028] Specifically, the weather radar 3 includes cloud measuring radar, rain measuring radar, and wind measuring radar.

[0029] Specifically, the remote monitoring center 2 includes a monitoring host and a server.

[0030] Specifically, the conditioning circuit includes an amplifier circuit and a filter circuit.

[0031] Specifically, the carriage is also equipped with a locator, which is connected to the host computer 7.

[0032] Specifically, the carriage is also equipped with a DC motor 8, an electrode drive board 9, and a bottom-level controller 10. The DC motor 8 is connected to the motor drive board 9, the motor drive board 9 is connected to the bottom-level controller 10, and the bottom-level controller 10 is connected to the host computer 7.

[0037] When this invention is in operation, it uses a weather radar for weather detection. The weather radar emits electromagnetic waves in the form of pulses. When the electromagnetic wave pulses encounter precipitation, most of the energy continues to propagate, while a small portion of the energy is scattered in all directions by the precipitation. The energy scattered backwards returns to the radar antenna and is received by the radar. Based on the characteristics of the precipitation system echo received by the radar, the characteristics of the precipitation system can be determined.

[0038] This invention also utilizes an atmospheric electric field meter to measure the atmospheric electrostatic field and its changes, and a lightning locator to detect electromagnetic waves radiated when lightning strikes occur, thereby enabling lightning disaster monitoring.

[0039] like Figure 3 As shown, signal conditioning mainly consists of an active low-pass filter and an amplifier circuit. The active low-pass filter is used to suppress noise and extract the useful signal, while the amplifier circuit is used to amplify the small signal to an appropriate range to match the input voltage of the AD converter.

[0040] The AD converter of this invention uses the AD7829. After conditioning by the front-end analog circuit, the voltage range is adjusted to be suitable for AD conversion. The AD sampling control circuit quantizes and encodes the voltage. The converted discrete signal is then sent to the DSP processor for relevant data processing.

[0041] This invention also utilizes solar energy for power supply, saving energy and reducing costs.

[0042] It should be noted that all components used in this utility model are existing products, and the connection relationships between the components are also conventional connection relationships in this field.
