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

[0027] like Figure 1-3 As shown, the utility model provides an AC uninterruptible power supply for a weather radar, comprising a housing 1, wherein a power input circuit, a rectifier 2, an inverter 3, a power output circuit, a battery 4, a static switch, and a bypass switch are arranged in the housing 1. The power input circuit is connected to the mains power. The rectifier 2 converts the AC power from the power grid into a DC voltage to supply the inverter 3 and simultaneously charges the battery 4. The inverter 3 converts the DC voltage into AC power and outputs it to the weather radar system through the power output circuit to power the weather radar system. The battery 4 is used to store backup power of the power supply. The utility model also includes a detection unit and a control unit 5. The detection unit is used to detect the input power supply and the working status of the battery. The control unit 5 is used to control the power on and off and automatic switching of the UPS power supply and automatic monitoring of the uninterruptible power supply. The detection unit is connected to the control unit 5;

[0028] The detection unit includes a power detection unit, a voltage detection unit, a phase detection unit, a temperature detection unit 6, a humidity detection unit 7, a vibration detection unit 8, an infrared detection unit 9, and a smoke detection unit 10. The power detection unit is used to detect the battery power, the voltage detection unit is used to detect the mains input voltage, the inverter output voltage, and the battery voltage, the phase detection unit is used to detect the mains phase and the inverter output phase, the temperature detection unit 6 is used to detect the battery temperature and the internal environment temperature of the uninterruptible power supply, the humidity detection unit 7 is used to detect the internal humidity data of the uninterruptible power supply, the vibration detection unit 8 is used to detect the impact force suffered by the uninterruptible power supply, the infrared detection unit 9 is used to detect the infrared radiation of the environment around the uninterruptible power supply, and the smoke detection unit 10 is used to detect the smoke data of the environment around the uninterruptible power supply;

[0029] The control unit 5 includes a microprocessor, a comparator, an alarm, a memory, and a wireless communication unit. The comparator, the alarm, the memory, and the wireless communication unit are all electrically connected to the microprocessor.

[0030] Specifically, the power input circuit includes an input filter for filtering noise and interference of the input power grid.

[0031] Specifically, the power output circuit includes an output filter for filtering out clutter and ripples in the alternating current output by the inverter.

[0032] Specifically, the inverter adopts a high-power IGBT module full-bridge inverter circuit.

[0033] Specifically, the microprocessor includes a single chip microcomputer.

[0034] Specifically, the control unit is connected to the host computer via a wireless communication unit.

[0035] Specifically, the host computer is connected to the server and the intelligent terminal.

[0036] Specifically, the housing is provided with a display screen and buttons, and the display screen and buttons are electrically connected to the microprocessor.

[0037] When the utility model is in operation, under normal AC power supply, the rectifier converts AC power into DC power, uses the input filter to eliminate noise and interference in the mains power, and charges the battery at the same time, and then supplies the inverter to convert DC power into AC power, providing a more stable power supply to the weather radar system.

[0038] When an abnormality occurs in the AC power supply or the rectifier fails, the battery pack provides DC power to the inverter, so that the AC output will not be interrupted, thereby protecting the weather radar system.

[0039] When an abnormal condition occurs in the inverter, such as a blown inverter fuse or short circuit, the inverter will automatically shut down to prevent damage. If the bypass AC power supply is normal at this time, the static switch will transfer the power supply to the bypass backup power supply for use by the weather radar system.

[0040] When the UPS needs maintenance or battery replacement and the load power supply cannot be interrupted, first disconnect the inverter switch, activate the maintenance bypass switch, and then disconnect the rectifier and bypass switch. AC power continues to supply AC power to the load through the maintenance bypass switch, allowing maintenance personnel to safely perform maintenance on the UPS.

[0041] The utility model uses a power detection unit to detect the battery power and sends it to the single-chip microcomputer for data processing and analysis. The single-chip microcomputer determines whether the battery power is sufficient through a comparator. If an abnormality occurs, an alarm is issued through an alarm, and the result is sent to the host computer via a wireless network at the same time, so that the management personnel can know and make timely management.

[0042] The utility model utilizes a power supply detection unit to detect the mains input voltage, the inverter output voltage, and the battery voltage, and sends them to a single-chip microcomputer for data processing and analysis. A comparator is used to determine whether the voltage data exceeds a set threshold. If it exceeds the set threshold, it is considered to be abnormal. If an abnormality occurs, an alarm is used to give an alarm reminder, and the result is sent to a host computer via a wireless network at the same time, so that management personnel can know and make timely management.

[0043] The utility model utilizes a phase detection unit to detect the mains phase and the inverter output phase, and sends them to the single chip microcomputer. The single chip microcomputer determines whether the phases of the two are consistent. If they are inconsistent, it is considered to be an abnormality, and an alarm is issued through an alarm. At the same time, the result is sent to the host computer via a wireless network, which is convenient for management personnel to know and make timely management.

[0044] The utility model uses a temperature detection unit to detect the battery temperature and the internal ambient temperature of the uninterruptible power supply, and sends the data to the single-chip microcomputer for data processing and analysis to determine whether the temperature data exceeds the set threshold. If it exceeds the set threshold, it is considered an abnormality, and an alarm is issued through an alarm, and the result is sent to the host computer at the same time, so that the management personnel can know and make timely management. Too high temperature can easily cause the battery capacity to decrease, and too low temperature can easily cause the battery to lose its storage performance and shorten its service life.

[0045] The utility model uses a humidity detection unit to detect the internal humidity data of the uninterruptible power supply and sends it to the single-chip microcomputer for data processing and analysis to determine whether the humidity data exceeds the set threshold. If it exceeds the set threshold, it is considered an abnormality and an alarm is issued through the alarm. At the same time, the result is sent to the host computer to facilitate management personnel to know and make timely management. Excessive humidity can easily cause damage to the equipment.

[0046] The utility model also uses a vibration detection unit to detect the impact force exerted on the uninterruptible power supply, and sends it to the single-chip microcomputer for data processing and analysis to determine whether the vibration force data exceeds the set threshold. If it exceeds the set threshold, it is considered an abnormality, and an alarm is issued through the alarm, and the result is sent to the host computer at the same time, so that the management personnel can know and make timely management. The impact of external force and long-term vibration can easily cause damage to the equipment.

[0047] The utility model also has an infrared detection unit that detects infrared radiation from the surrounding environment of the uninterruptible power supply and sends it to the single-chip microcomputer for data processing and analysis to determine whether the data exceeds a set threshold. If the set threshold is exceeded, it is considered an abnormality and an alarm is issued through the alarm. At the same time, the result is sent to the host computer to remind the staff that the surrounding environment is abnormal and to avoid placing the power supply close to the heat source.

[0048] The utility model uses a smoke detection unit to detect smoke data in the environment around the uninterruptible power supply; and sends the data to the single-chip microcomputer for data processing and analysis to determine whether the data exceeds a set threshold. If the set threshold is exceeded, it is considered to be abnormal, and an alarm is issued through an alarm. At the same time, the result is sent to the host computer to remind the staff of the abnormal environment and avoid dangers such as explosions caused by fire.

[0049] The utility model also installs a UPS power supply lightning arrester of appropriate capacity on the uninterruptible power supply display screen to prevent the impact of lightning.
