[0002] Reachctrl Power, also known as an intelligent PDU, IP power supply, smart power supply, or rack-mount power distribution unit, combines power distribution and management capabilities. It monitors parameters such as supply voltage, frequency, and output current per channel. It also enables remote control, centralized management, automatic cycle control, security management, and reliability management, making it a valuable aid in power management.

[0003] Currently, smart PDUs on the market can only indirectly determine whether a branch device socket is loose by monitoring the current in each branch. If the device current is zero, it cannot detect whether it is being plugged in or unplugged. Computer rooms contain a wide variety of backup devices. When a backup device is powered off or has a near-zero standby current, it is impossible to detect whether the device has lost power. There are no on-site indicator lights for inspectors to check. If the primary device fails or goes offline, the backup device will not function properly, resulting in serious communication interruptions. Summary of the Invention

DETAILED DESCRIPTION

[0017] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1-4 As shown, in this embodiment, an intelligent PDU with plug-in and plug-out hardware detection includes a PDU body 1. The PDU body 1 is provided with a plurality of spaced-apart socket units. The PDU body 1 is provided with a plurality of LED indicator lights 7. The LED indicator lights 7 correspond one-to-one to the socket units. Each socket unit includes three sockets 5: an upper socket, a left socket, and a right socket. The inner cavity of the PDU body 1 is provided with a plurality of protective door units. The protective door units correspond one-to-one to the socket units. The protective door units are arranged below the socket units. The protective door unit includes a protective door outer shell 8. A protective door body 16 is provided in the protective door outer shell 8. The protective door body 16 has an upper socket protection door 6, a left socket protection door 10, and a right socket protection door 11. The upper socket protection door 6 corresponds to the upper socket, the left socket protection door 10 corresponds to the left socket, and the right socket protection door 11 corresponds to the right socket. A protective door fixing post 13 is positioned within the protective door housing 8. A waist-shaped sliding slot 14 is defined on the protective door body 16, allowing the protective door body 16 to move within the protective door housing 8. The protective door fixing post 13 cooperates with the sliding slot 14 and is positioned at one curved portion of the sliding slot 14. Conductive metal plates 15 are positioned on the other curved inner wall of the sliding slot and on the outer periphery of the protective door fixing post. The two conductive metal plates 15 form a limit switch. Initially, the spacing between the two conductive metal plates corresponds to the length of the upper socket protective door. The limit switch is electrically connected to an LED indicator. An elastic return element is positioned between the bottom of the protective door body 16 and the protective door housing 8. When a plug is inserted into the socket unit, it is first inserted into the upper socket. The upper plug pushes open the upper socket protective door 6, pushing the protective door body down along the protective door housing. This pulls one conductive metal plate on the curved inner wall toward the other conductive metal plate on the fixing post. When the two conductive metal plates come into contact, the LED indicator lights up. When the plug is removed, the spring return element resets the protective door body, causing the two conductive metal plates to separate and the LED indicator to turn off.

[0019] The above-mentioned elastic return member includes two groups of spring fixing column units arranged at intervals. Any spring fixing column unit includes two spring fixing columns 9 arranged symmetrically up and down. One spring fixing column 9 is fixed at the bottom of the protective door body 16, and the other spring fixing column 9 is fixed at the protective door outer shell 8. The two spring fixing columns 9 are connected by a spring 12.

[0020] Two symmetrically arranged guide rails 17 are provided on the protective door shell, and two symmetrically arranged guide blocks are provided on the protective door body 16. The guide blocks are symmetrically arranged on both sides of the sliding groove, and the guide blocks are clamped on the corresponding guide rails 17 to guide the movement of the protective door body.

[0021] It is also provided with a network port 2 and a wire hole. The wire 3 electrically connected to the limit switch and the LED indicator light passes through the wire hole and is electrically connected to the signal processor. A display screen 4 is provided on the PDU body for displaying relevant information sent by the signal processor. The network port 2 is connected to the superior centralized monitoring and alarm center via a network cable, so that relevant information is transmitted to the superior centralized monitoring and alarm center. The plug pushes open the upper socket protection door, pushing the protective door body down along the protective door shell, so that the limit switch is closed, generating an insertion signal, which is transmitted to the LED indicator light 7 and the signal processor 18. The LED indicator light and the display screen display relevant information, which can also be transmitted to the superior centralized monitoring and alarm center through the network port. If a plug is unplugged or the line is disconnected, the spring pushes the protective door body upward, separating the two conductive metal sheets, and the limit switch opens. The opening signal is transmitted to the LED indicator light and the signal processing CPU, generating a pull-out or disconnection signal. The display screen displays relevant information, which can also be transmitted to the superior centralized monitoring and alarm center through the network port.

[0022] This application features an LED indicator on the PDU itself. This status allows on-site inspections to identify disconnected devices. Regardless of whether a device is in use, the device can monitor the status of its power outlet to detect loose plugs and transmit signals to the signal processor and the higher-level centralized monitoring and alarm center for monitoring and alarming. The protective door and travel switch are integrated into a single structure, saving space and providing greater efficiency.

[0023] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
