Description

Technical Field

[0001] This invention relates to the field of remote control technology for power strips or sockets, and particularly to a method and related equipment for remote control of power strips. Background Technology

[0002] In scenarios such as corporate offices, shopping malls, and campuses, it is necessary to ensure the flexibility of office and teaching while achieving energy conservation and emission reduction. Many devices need to be remotely controlled for power on and off, which is suitable for remote work and can also ensure remote management services.

[0003] Many businesses have numerous engineers' computers and debugging equipment that require remote power-on / off control from home to enable remote work. Internal devices such as printers, water dispensers, and servers also need remote or scheduled power-on / off control to save energy and reduce manual workload. Businesses and online stores also require remote control or scheduled power on / off control of wireless WiFi devices, cameras, and other network terminals. These industry application scenarios involve both wired networks and PoE switches, necessitating a smart, energy-efficient, and low-cost network and power supply solution that allows users to remotely or scheduledally control the power on / off of certain network terminal devices or peripheral network power supply equipment.

[0004] Currently, power strips and sockets on the market are generally divided into smart and non-smart types. The biggest feature of smart power strips is that users can remotely control the power strip's switch via mobile phones, tablets, and other terminal devices, thereby remotely starting, stopping, or restarting devices connected to the power strip. Current remote control technology for smart power strips primarily uses wireless technology to connect to the internet, enabling interconnection with remote mobile phones and other terminal devices. The main wireless technologies used are Wi-Fi and Bluetooth, connecting to home or office networks, or directly connecting to the internet via 4G / 5G. These power strips also require a CPU or MCU controller as the "brain" of the smart socket and an AC power module to provide DC power. Their research and development costs and hardware costs are relatively high. Currently, a single-hole smart socket costs over 70 yuan, and a smart power strip costs over 200 yuan. Summary of the Invention

[0005] This invention provides a method and related equipment for remotely controlling power strips. The purpose is to remotely control the power strip's switching without using wireless communication technology or embedding a CPU or MCU in the power strip. This is achieved by using existing network cables (twisted pairs) and simple analog circuits embedded in the power strip, along with a remote PoE switch, to remotely control the power strip's switching power.

[0006] To achieve the above objectives, the present invention provides a method and related equipment for remotely controlling power strips, including: Step 1: Install the Ethernet cable interface and the terminal PD power receiving device on the power strip. Connect the Ethernet cable interface to the remote PoE switch via the Ethernet cable. Step 2: The user, user power strip ID and description information, PoE switch and port are bound together, and an association table is established and stored in the PoE switch and network management server software tables. Step 3: The user sends a power switch or timed power switch operation command to the remote user's power strip via a remote control power strip APP installed on their mobile phone or computer. Step 4: The network management server receives the user's instruction and sends the instruction to the PoE switch corresponding to the user's power strip ID through the network management protocol. The PoE switch responds to the instruction and performs power on or off operation on the corresponding PoE port. Step 5: The PD power receiving module and switching circuit inside the remote user's power strip detect a change in the power supply level at the Ethernet port of the power strip, triggering the relay to close or open, thereby controlling the connection and disconnection of the AC power supply to the power strip.

[0007] Furthermore, the power strip should have at least one Ethernet RJ45 port as a control signal input interface, which connects to a remote PoE switch via a network cable. The power strip can also provide one Ethernet RJ45 port as a network output interface, connecting to other network terminal devices via a network cable to provide Ethernet communication for those devices.

[0008] Furthermore, the power strip also contains a network transformer, which separates the PoE power input and Ethernet communication signal data from the Ethernet RJ45 network interface.

[0009] Furthermore, the power strip also contains a PD power receiving module. The PD power receiving module negotiates and performs signature detection with the PoE switch to securely obtain DC power from the PoE switch, thus providing DC power to the backend access devices.

[0010] Furthermore, the power strip also contains a switch control circuit that provides switching signals to subsequent circuits. When the switch control circuit detects that the PD power receiving module is providing power, it triggers an on signal; if it detects that the power supply is disconnected, it triggers an off signal.

[0011] Furthermore, the power strip also contains a relay. The relay is triggered to close and open by a switch signal. When the relay is closed, it connects the external AC power supply to the socket hole on the power strip. When the relay is open, it disconnects the external AC power supply from the socket hole on the power strip.

[0012] Furthermore, the power strip also contains a USB charging port and a 5V transformer. The power supplied by the PD power receiving module is transformed by the 5V transformer and then supplied to the USB charging port to charge mobile phones and other terminal devices.

[0013] Furthermore, power strips can be remotely managed through remote network management software and related systems. Remote management methods include: Configure users, user power strip IDs and descriptions, PoE switch and port number association entries, and trigger user power strip switching or timed switching actions via the command line or local web page of the PoE switch. Simultaneously, the cloud-based network management platform provides the same configuration page as the local web page for the PoE switch. The administrator can install and run the remote control power strip APP software on the mobile PC, connect the network cable connected to the PoE switch to the administrator PC, enter the user and power strip information, and the APP software will automatically complete the binding between the user, user power strip ID and description, and PoE switch port on the PoE switch through the remote control power strip authentication protocol, which is a Layer 2 private Ethernet protocol, and automatically establish an association table and synchronize it to the cloud network management platform. Users can remotely control power strips via a mobile app, select the power strip ID to be remotely controlled, and trigger corresponding power-on or power-off actions or timed power-on / off actions. The user's mobile phone then sends the command to the cloud network management server via the internet. The cloud network management server looks up the power strip ID in the software association table and sends the user command to the PoE switch bound to the power strip through the network management protocol. After receiving the protocol message, the PoE switch parses the user command and initiates power-on or power-off operations to the corresponding PoE switch port, thereby controlling the connection and disconnection of AC power to the remote power strip.

[0014] Furthermore, the data content includes username, user power strip ID and description, PoE switch and port number, timing information, and action commands.

[0015] The above-described solution of the present invention has the following beneficial effects: This invention involves installing an Ethernet cable interface and a terminal PD power receiving device on a power strip, connecting the interface to a remote PoE switch via a network cable. The user, the power strip ID and description, the PoE switch, and the port are bound together, and an association table is established and stored in the PoE switch and network management server software tables. The user initiates power-on or timed power-off commands to the remote user power strip via a remote control app installed on their mobile phone or computer. Upon receiving the user command, the network management server sends a command to the PoE switch corresponding to the user power strip ID via the network management protocol. The PoE switch responds to the command, turning the power supply to the corresponding PoE port on or off. The PD power receiving module and switching circuit within the remote user power strip detect changes in the power supply level at the Ethernet port, triggering a relay to close or open, thereby controlling the AC power connection and disconnection of the power strip. Compared to existing technologies, this invention, based on a traditional ordinary power strip, designs a simple analog control circuit. It requires no software programs, AC power modules, CPUs, MCUs, or other processing chips, and no wireless communication chips such as WiFi, Bluetooth, 4G, or 5G. It achieves network interconnection through the user's existing wired network and mobile phone terminals, and controls the power on and off of the provided power strip through a PoE switch in the user's network. This invention adds minimal-cost hardware circuitry to a standard non-smart power strip, enabling remote or timed control of the power strip's switching on and off. It can be widely applied and achieves the same effect as smart power strips controlled by wireless communication and MCUs on the market. This significantly reduces the investment cost for users in building intelligent office systems and achieves energy-saving, flexible office operations and intelligent equipment management.

[0016] Other beneficial effects of the present invention will be described in detail in the following detailed description section. Attached Figure Description

[0021] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] This invention addresses existing problems by providing a method and related equipment for remotely controlling power strips. The remote control method and related equipment of this invention are applicable not only to power strips but also to AC switch control devices such as sockets. The use of a power strip here is merely an example and not intended to limit the application.

[0023] It should be understood that a PoE (Power Over Ethernet) switch is a technology that, without any modification to the existing Ethernet Cat.5 cabling infrastructure, can transmit data signals to some IP-based terminals (such as IP phones, wireless LAN access points, network cameras, etc.) while also providing DC power to these devices. PD (Power Device) refers to a terminal device that can operate by being powered by the network cable of a PoE switch and complete data communication transmission.

[0024] like Figure 1 As shown, an embodiment of the present invention provides a method and related equipment for remotely controlling a power strip. The power strip is connected to a PoE switch via a network cable, and the user remotely controls the AC power supply to and from the power strip via a mobile phone.

[0025] Remote control methods and related equipment include: Step 1: Install the Ethernet cable interface and the terminal PD power receiving device on the power strip. Connect the Ethernet cable interface to the remote PoE switch via the Ethernet cable. Step 2: The user, user power strip ID and description information, PoE switch and port are bound together, and an association table is established and stored in the PoE switch and network management server software tables. Step 3: The user sends a power switch or timed power switch operation command to the remote user's power strip via a remote control power strip APP installed on their mobile phone or computer. Step 4: The network management server receives the user's instruction and sends the instruction to the PoE switch corresponding to the user's power strip ID through the network management protocol. The PoE switch responds to the instruction and performs power on or off operation on the corresponding PoE port. Step 5: The PD power receiving module and switching circuit inside the remote user's power strip detect a change in the power supply level at the Ethernet port of the power strip, triggering the relay to close or open, thereby controlling the connection and disconnection of the AC power supply to the power strip.

[0026] In embodiments of the present invention, such as Figure 2 As shown, specifically including: The power strip is designed with an input Ethernet cable RJ45 interface, which connects to a remote PoE switch via a network cable.

[0027] Ideally, the power strip should also have an RJ45 Ethernet port for connecting to computers, IP phones, and other terminal devices via Ethernet cable.

[0028] The power strip has an internal PD power receiving module circuit. The PD module negotiates with the remote PoE switch through the IEEE 802.3af, IEEE 802.3at, and IEEE 802.3bt protocols, thereby triggering the PoE switch to supply power to the PD.

[0029] In this embodiment of the invention, if the peer is a non-standard PoE switch, the switch adopts a forced power supply method and does not need to use the IEEE 802.3 standard for detection and negotiation. The remote control power strip of this invention adopts the same non-standard PoE power supply signature detection method to complete normal power supply and normal power reception, while avoiding the connection of non-PD powered terminals, which could lead to short circuits, burnt circuit boards, and other phenomena.

[0030] The power strip is designed with a switching circuit. After the power strip receives the PoE power supply level, it triggers the MOSFET switch, thereby controlling the relay switch.

[0031] Ideally, the power strip should have a transformer circuit. The PoE power supply voltage is generally quite high, with standard PoE power supply being 48V, while non-standard PoE power supply is generally 12V, 24V, 48V, etc., which need to be stepped down to 5V by a transformer to power the USB interface.

[0032] The power strip is designed with a relay, which is used to switch the 220V AC power on and off, thereby controlling the power supply and disconnection of the 220V AC sockets on the power strip, and thus controlling the power on and off of external devices connected to the power strip.

[0033] The power strip design includes a network transformer circuit. This network transformer separates the data and power on the network RJ45 interface, ensuring that only Ethernet data packets are transmitted through the network cable from the RJ45 output interface, without the PoE power supply, thus enabling communication with other terminals. In this embodiment, if the output also requires a PD device, the corresponding PoE power supply can still be applied to the RJ45 output interface.

[0034] In embodiments of the present invention, such as Figure 3 As shown, specifically including: The network management server can be deployed in the cloud or locally, depending on the user's needs, without any restrictions. Users can install network management software to manage users, PoE switches and power strips via mobile phone or computer web interface. They can also remotely control power strips via mobile phone, network management platform, local serial port commands of PoE switch or web interface. USB charging terminals on power strips can be used for digital devices such as mobile phones, power banks, and speakers; The output Ethernet cable RJ45 interface allows connection to Ethernet network terminal devices such as computers, IP phones, video conferencing devices, and advertising screens via network cable; The AC sockets provided by the power strip can be used to connect AC electrical equipment such as computers, printers, smart screens, conference systems, and water heaters via power cords.

[0035] In this embodiment of the invention, the PoE switch needs to support PSE power management. After the PoE switch is up and running, it needs to connect to the user's internal network and the Internet, and communicate with the cloud network management platform for remote control of power strips. If the server is deployed locally, it communicates with the local server. Communication between the PoE switch and the network management server can be achieved through network management protocols such as TR069 and MQTT built into the switch. The PoE switch supports local web or command-line management, providing a management page for configuring port power management functions.

[0036] Specifically, the PoE switch performs remote control of power strips, establishing a software table associating users, their bound power strip IDs, and PoE ports. This association table needs to be synchronized to the network management server in real time. The PoE switch uses the NTP protocol or a hardware clock for time synchronization and calibration to achieve relatively accurate time zones and times, meeting users' timed control needs. Based on users and their power strip IDs, a single user can bind multiple power strips, with different power strips distinguished by their IDs and descriptions. According to the user's timed power-on or power-off command, the switch looks up the association table and automatically turns the PoE port corresponding to the power strip ID on or off at the user-specified time. If the PoE switch receives an immediate power-on or power-off command from the user, it immediately turns the corresponding PoE port on or off according to the power strip ID association table.

[0037] In this embodiment of the invention, the power strip and the PoE switch are generally not in the same physical location. Administrators cannot quickly locate the PoE network cable assigned to the user's power strip and the location of the connected PoE port. Therefore, a scientific and reasonable method is needed to establish a user, power strip ID, and PoE port association table.

[0038] Specifically, there are two main methods: 1. Specified Binding Method: This invention uses a combination of log reporting and management registration to accurately locate port positions. The user inserts the other end of the network cable connected to the PoE switch into a power strip. Since the power strip integrates a PD power receiving module, the PoE switch detects the PD load and initiates power supply from the corresponding network cable connection port. At this time, the PoE switch scans all port power supply statuses and, upon discovering a new port with a connected load, initiates an online notification through the network management protocol, reporting the port number and PoE switch IP address to the network management server. The network management server responds via notification messages or network administrator login. The administrator manually binds user information, the user's power strip ID and description, the online PoE switch, and the corresponding port on the user management page, and synchronizes the established association entries to the corresponding PoE software table. Administrators can also perform the above binding operations by logging into the corresponding PoE switch's web or serial command management page. 2. Authentication and Registration Method Binding: This invention designs a management authentication and registration application software. The software provides a configuration page containing the username, user power strip ID, and power strip description. The software is installed on a laptop or other mobile terminal computer. The administrator connects the network cable from the PoE switch to the computer's network port. The software communicates with the PoE switch via a Layer 2 private Ethernet protocol. The computer initiates an authentication and registration request through this protocol. Upon receiving the request protocol message, the PoE switch matches the protocol number and destination MAC address (this invention uses Ethernet protocol number 0x5483 and destination MAC address 01:80:c2:a4:b5:cc, but is not limited to these values). If the authentication and registration request message of this invention is received, the message will be sent to the CPU and handed over to the PoE switch remote control power strip task program. The program extracts the user information and power strip information carried in the message according to the TIV data structure of the protocol, and then automatically binds it with the PoE port that received the message. It also notifies the network management server through the network management protocol. The network management server records the association information in the user power strip association software table. If the configuration is successful, the network management server sends a response message to the PoE switch. After receiving the successful response message, the PoE also sends a Layer 2 private protocol response message from the corresponding associated PoE port to the administrator's mobile computer. After receiving the response message, the authentication and registration software on the computer prompts that the configuration is successful, and the binding operation is completed.

[0039] Specifically, once the binding process is complete, the user can remotely control their power strip. The specific process is as follows: Users install a remote control power strip APP on their mobile phones. Users apply for a username through the APP. The user's APP sends a username registration request to the network management server. The server confirms the request with the network administrator before the application is successful. Only users who have successfully applied can log in to the APP and establish a network connection with the network management server. The username of the user who logs in to the APP is the user, power strip ID, and user in the port association table recorded in the network management server. After a user logs in, if the network management server has a record of the user's association table, it will send the association data table to the user's mobile app and display the associated power strip ID and description information in the app. At this time, the user can view, set, or delete the power strip through the app. If the user needs to power on or off the power strip, or needs to schedule its on / off operation, the user can submit a configuration request through the app. The app will then send the user's configuration command to the network management server. The network management server will find the corresponding PoE switch IP address through the association table. The network management server will then send the user configuration command message to the corresponding PoE switch via the network management protocol. After receiving the command message, the PoE switch will report it to the remote control power strip processing task. The processing task will execute the user's command and perform power on or off actions on the corresponding PoE port.

[0040] Specifically, when the PoE port triggers power-on, a corresponding high-voltage signal is transmitted to the connected power strip via the network cable. After receiving power from the network cable, the power strip separates the power and data through a network transformer. The separated Ethernet data packets communicate with external terminals through another output port. The separated power is then transformed to 5V by the transformer to power the USB interface. Simultaneously, the power strip's switch control circuit reads the PD module's level and triggers the MOSFET to close, thereby triggering a rising edge signal to the relay. Upon receiving the rising edge signal, the relay triggers the switch to close, thus connecting the AC power supply to the AC device plugged into the power strip. If the PoE port triggers power-off, there is no power loaded on the connected power strip's network cable, causing the power strip's PD module to power down, and the USB interface will also power down. The MOSFET trigger pin's level signal drops to a low level, triggering the relay switch to open, thus disconnecting the external AC power supply from the power strip plug, and powering off the corresponding external AC device plugged into the plug.

[0041] Specifically, the data content package includes: This includes the username, user power strip ID and description, PoE switch and port number, timing information, and action commands.

[0042] In this embodiment of the invention, an Ethernet cable interface and a terminal PD power receiving device are installed on the power strip. The Ethernet cable interface is connected to a remote PoE switch via a network cable. The user, the user power strip ID and description information, the PoE switch and port are bound together, and an association table is established and stored in the PoE switch and network management server software tables. The user initiates a power switch power-on or timed power-off operation command to the remote user power strip through a remote control power strip APP installed on a mobile phone or computer. The network management server receives the user command and sends a command to the PoE switch corresponding to the user power strip ID through the network management protocol. The PoE switch responds to the command and performs power-on or power-off operation on the corresponding PoE port. The PD power receiving module and switching circuit in the remote user power strip detect the change in the power supply level of the power strip's Ethernet port, triggering the relay to close or open, thereby controlling the access and disconnection of the power strip's AC power. Compared to existing technologies, this invention, based on a traditional ordinary power strip, designs a simple analog control circuit. It requires no software programs, AC power modules, CPUs, MCUs, or other processing chips, and no wireless communication chips such as WiFi, Bluetooth, 4G, or 5G. It achieves network interconnection through the user's existing wired network and mobile phone terminals, and controls the power on and off of the provided power strip through a PoE switch in the user's network. This invention adds minimal-cost hardware circuitry to a standard non-smart power strip, enabling remote or timed control of the power strip's switching on and off. It can be widely applied and achieves the same effect as smart power strips controlled by wireless communication and MCUs on the market. This significantly reduces the investment cost for users in building intelligent office systems and achieves energy-saving, flexible office operations and intelligent equipment management.

[0043] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
