Description
Technical Field

[0002] With the growing demand for large-scale node power management, the requirements for the stability and intelligence of power management devices are also increasing. The demand is particularly evident in scenarios with a large number of power control nodes, such as university laboratories, equipment rooms, and office workstations. However, existing power management units face the problem of low efficiency when dealing with large-scale equipment. At the same time, when dealing with extreme environments, the power managers are mostly scattered and difficult to fix, and the interfaces lack corresponding protection measures, which leads to failures, resulting in insufficient system stability and most of them cannot provide status detection and reporting feedback at the same time. These problems make the current power management units unable to meet the growing demand in practical applications.
[0003] With the rapid development of wireless communication technology, the demand for wireless power management devices has become increasingly prominent. Wireless power management devices can get rid of the constraints of traditional wired connections and provide greater flexibility and convenience. However, existing wireless power management solutions are mostly single-point control, or the networking solutions are complex, using public network transmission, facing network security and other issues, and there are still many challenges, such as the need for specific equipment to provide networking support, making it difficult to modify existing facilities, requiring public network data transmission, posing hidden dangers to safety, and only providing a series of problems such as single-point control. Therefore, it has become an urgent need to research and develop an efficient, stable, and intelligent wireless power management device. Utility Model Content

[0046] The purpose of this application is to provide a distributed wireless power management device, aiming to achieve efficient, stable and intelligent management of power supply.
[0047] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0048] In an exemplary embodiment, Figure 1-Figure 3 As shown, the distributed wireless power management device in this embodiment includes: a relay 1, an optocoupler 2, a voltage monitoring module 3, a current monitoring module 4, a wireless module 5 and a control MCU 6; the voltage monitoring module 3 is a voltage transformer, and the current monitoring module 4 is a current Hall sensor.
[0049] The optical coupler 2, the voltage monitoring module 3, the current monitoring module 4 and the wireless module 5 are all connected to the control MCU 6; the relay 1 is connected to the optical coupler 2; the relay 1, the voltage monitoring module 3 and the current monitoring module 4 are all connected to the controlled power supply.
[0050] The voltage monitoring module 3 is used to collect voltage parameters of the controlled power supply.
[0051] The current monitoring module 4 is used to collect current parameters of the controlled power supply.
[0052] The wireless module 5 is used to obtain external control signals.
[0053] Control MCU6 for:
[0054] Obtain voltage parameters, current parameters and external control signals.
[0055] An internal control signal is generated based on the voltage parameter, the current parameter and the external control signal, and the internal control signal is sent to the optocoupler 2.
[0056] Optocoupler 2 is used to convert the internal control signal into a 5V voltage signal and send the 5V voltage signal to relay 1.
[0057] The voltage parameters, current parameters, external control signals and internal control signals are sent to the wireless module 5 .
[0058] Relay 1 is used to control the on and off of the controlled power supply based on a 5V voltage signal.
[0059] The wireless module 5 is also used to send voltage parameters, current parameters, external control signals and internal control signals to an external host computer.
[0060] Specifically, the wireless module uses the ESP32-S3 module of Espressif Technology, establishes communication with the control MCU through a TTL serial port level, uploads the voltage parameters and current parameters collected by the control MCU through WIFI, and monitors the external control command signal in real time, sends it to the control MCU, and controls the MCU to output the control level (i.e., the internal control signal) to complete the relay switch control.

[0065] Specifically, the working status indication and switching module is used to switch the status of the power management device through a dip switch, and to indicate the status of the power management device through a dual-color LED. When the power management device is in the network configuration state, the wireless module works in the SoftAP mode, and the user can send configuration instructions through the wireless hotspot to configure the network parameters of the device (including: gateway, subnet mask, IP address, DNS server); when the power management device is in normal working state, the device automatically reads the configuration information and completes the network connection and automatically configures the network parameters.

[0071] Specifically, the control MCU controls the controlled power supply by outputting a control level and combining the opening and closing of the optocoupler to control the relay. After the 220V AC power enters the power management device, the 220V AC voltage is first converted into a 5V DC voltage through the Mean Well IRM-10-5 power module group in the power conversion module, where the DC 5V can power the relay, voltage monitoring module, current monitoring module, wireless module and control MCU. At the same time, the AMS1117 power conversion chip in the power conversion module converts the 5V DC into 3.3V DC for use by the optocoupler.
[0072] As an optional implementation, the distributed wireless power management device further includes: a manual control switch; the manual control switch is connected to the relay.
[0073] The manual control switch is used to realize manual control of the relay.
[0074] Specifically, the manual control switch provides a manual control function for the relay. The manual control switch is independent of the control MCU and directly controls the relay to be turned on or off through the DIP switch.
[0075] As an optional implementation, the distributed wireless power management device also includes: a housing; a relay, an optocoupler, a voltage monitoring module, a current monitoring module, a wireless module, a control MCU, a working status indication and switching module, a power conversion module and a manual control switch are all arranged in the housing.

[0077] As an optional implementation, the housing ground provided on the housing is isolated from the digital ground by means of an isolation mounting hole.
[0078] As an optional implementation, the housing includes: a chassis and a cover plate.
[0079] The joints of the chassis adopt a process combining conductive oxidation and metal sealing. A groove is opened between the chassis and the cover plate, and a conductive rubber strip is arranged in the groove. Conductive oxidation and metal sealing layers are arranged in the groove and on the joint surface between the cover plate and the chassis.
[0080] As an optional implementation, the control MCU adopts a STM32F103C8T6 single-chip microcomputer.
[0081] As an optional implementation, the voltage transformer uses a ZMPT107 micro precision voltage transformer chip.
[0082] Specifically, the voltage transformer uses a ZMPT107 micro-precision voltage transformer chip to sample the AC voltage. The low-voltage side output end of the ZMPT107 micro-precision voltage transformer chip is connected to the ADC port of the control MCU through a wire. The control MCU samples the AC voltage and calculates the real-time voltage parameters through the numerical changes.
[0083] As an optional implementation, the current Hall sensor uses an ACS712ELCTR-20A-T chip.
[0084] Specifically, the output port of the ACS712ELCTR-20A-T chip is connected to the ADC port of the control MCU using a wire.
