Technical Field

[0002] Meteorological radar is a complex high-frequency electronic device. In order to ensure its stable working performance, the meteorological department needs to conduct regular inspections and maintenance. In order to detect the electrical performance parameters of the meteorological radar's transmitter, receiver, signal processor and other subsystems or the whole machine, a variety of precision instruments such as oscilloscopes, spectrum analyzers, signal sources, power meters, multimeters, etc. are generally required. At the same time, as a large and medium-sized observation equipment, meteorological radar does not have the conditions to be transported back to the laboratory for testing after installation, so it is necessary to place a variety of instruments at the radar work site for on-site testing. Most of the instruments working at high frequencies are laboratory equipment, which have certain requirements for the operating environment. In addition, different test items require different instruments, and each set of instruments needs to be powered separately.

The two modules, the peripheral power supply and voltage regulation module and the switch control module, jointly realize independent power supply and monitoring of peripheral devices. Through the peripheral power supply and voltage regulation module, stable power input can be provided for different peripheral devices.

[0037] like Figure 5 As shown, the switch control module includes a power output selection circuit of a portable meteorological radar on-site comprehensive test instrument main control module connected to the portable meteorological radar on-site comprehensive test instrument main control module, a signal source power output selection circuit connected to the signal source power supply voltage regulation circuit, a spectrum analyzer power output selection circuit connected to the spectrum analyzer power supply voltage regulation circuit, a power meter power output selection circuit connected to the power meter power supply voltage regulation circuit, an oscilloscope power output selection circuit connected to the oscilloscope power supply voltage regulation circuit, and a multimeter power output selection circuit connected to the multimeter power supply voltage regulation circuit; the power output selection circuit of the portable meteorological radar on-site comprehensive test instrument main control module, the signal source power output selection circuit, the spectrum analyzer power output selection circuit, the power meter power output selection circuit, the oscilloscope power output selection circuit and the multimeter power output selection circuit are connected to the portable meteorological radar on-site comprehensive test instrument main control module.

When the peripheral device is not in use, it will be powered off. It can control the on and off of the peripheral device according to actual needs, realize flexible management of the equipment, save battery power, and extend the battery power supply working time of the portable weather radar field comprehensive test instrument.

[0040] The peripheral electrical parameter detection module detects the current electrical parameter information of each channel peripheral module in the switch control module in real time, such as voltage, current, etc., and transmits this information to the power management main control module. By analyzing this information, we can understand the current working status of each peripheral device.

The power management main controller analyzes the current battery power situation and controls whether the charging circuit continues to charge the battery. Ensure that the charging circuit is disconnected when the battery is full, and continue to charge when the battery voltage is lower than 80%, so as to prevent the danger caused by long-term full-power charging of the battery and extend the service life of the battery. At the same time, the status will be displayed according to the temperature and humidity information, and the user will understand the temperature and humidity situation inside the portable weather radar on-site comprehensive test instrument in real time.

[0046] The above specific implementations do not constitute a limitation on the protection scope of the present disclosure.
