Embodiment 1

[0034] see figure 2 , U14 is a POE power transformer, U3 is a power management chip, V6 is a photocoupler, U5 is a triode, L15 is a winding inductor, D9, D3, D7 are diodes, R44, R42, R41 are resistors, the external DC of this circuit The power supply DC is plugged into the J5 power supply interface. The voltage from POE is conjugate-filtered by the winding inductor L15, and then enters the power management chip U3 for PWM to perform pulse width modulation. Chipset and module power supply. Diode D9, diode D3, and diode D7 are fixed voltage clamps to prevent power management chip U3 from being damaged by excessive voltage. Photocoupler V6 collects the adjusted current signal, and feeds back the working status of each chipset and module on the motherboard to power management chip U3 , the power management chip U3 adjusts the output power of the POE power transformer U14, and the voltage output by the POE power transformer U14 passes through the reference voltage point composed ...

Abstract

The invention relates to a wireless network system, concretely relating to an MESH network system capable of adjusting power supply power automatically. The MESH network system comprises a power device and a power supply system. The power device comprises a processor module, a memory module, a peripheral equipment interface module, and a network interface module. The power supply system comprises a power supply management chip and a power supply power control module. The power supply power control module comprises a POE power transformer and an optoelectronic coupler. The power supply management chip adjusts output power of the POE power transformer according to a feedback signal. The MESH network system has the following advantages that: according to work power of each power device, the power supply system of the MESH network system adjusts power of a DC power supply automatically, the power supply is subjected to filtering, an interference signal is removed, and POE power supply security and equipment stabilization are ensured.

Description

technical field [0001] The invention relates to a wireless network system, in particular to a MESH network system capable of automatically adjusting power supply. Background technique [0002] Wireless AP (AP, Access Point, wireless access node, session point or access bridge) not only includes simple wireless access point (wireless AP), but also wireless router (including wireless gateway, wireless bridge) and other devices collectively. [0003] With the popularity of wireless routers, if there is no special explanation in the current situation, the so-called wireless AP is generally understood as a simple wireless AP to distinguish it from a wireless router. It mainly provides access from wireless workstations to wired LANs and from wired LANs to wireless workstations, and wireless workstations within the coverage of the access point can communicate with each other through it. [0004] A simple wireless AP is a wireless switch that only provides a function of wireless s...
