Accompanying drawing explanation
Fig. 1: the system block diagram of the PoE switch of a kind of uninterrupted power supply of the utility model;
Fig. 2: the workflow diagram of the POE switch of a kind of uninterrupted power supply of the utility model.
Embodiment
Present composition graphs 1, Fig. 2 illustrate.
Execution mode one: PoE switch uninterrupted power supply controller module is connected between PoE system main power source and PoE system module as shown in Figure 1, this module can be matched according to the demand of client.Auxiliary power module, MCU micro controller module, communication interface circuit module are connected with PoE system module successively; PoE switch main power source module, DC/DC reduction voltage circuit module, charging circuit module, DC/DC booster circuit module are connected successively, and are connected with PoE system module by either-or switch; MCU microcontroller is connected with PoE system module by either-or switch; MCU micro controller module is connected with DC/DC reduction voltage circuit module, charging circuit module, DC/DC booster circuit module respectively; Batteries module is provided with between charging circuit module and DC/DC booster circuit.Connection batteries like this does not just need independently charge power supply, decreases some transform parts of power supply, improves efficiency, energy-conserving and environment-protective.
Execution mode two
Fig. 2 shows workflow diagram of the present utility model, first auxiliary power module exports the voltage of 3.3V to MCU micro controller module and the use of communication interface circuit module, its input power is from PoE switch main power source module (if there is power supply, preferentially using) or batteries module (when PoE switch main power source module does not have electricity).
MUC microcontroller is used for whether monitoring PoE switch main power source module in real time at normal power supply, if there is no normal power supply, MUC micro controller module first detects the electricity of batteries module, MUC micro controller module communicates with PoE system module simultaneously, first calculate power required for outer source device, if detect that the electricity of batteries module enough allows each outer source device normally work, so MUC microprocessor controls DC/DC booster circuit module work, make DC/DC booster circuit module that the voltage between the boost in voltage of batteries to 50 ~ 57V is supplied to PoE system module to use, and make PoE system module be switched to uninterrupted power supply powering mode.When MUC microcontroller detects that accumulator electric-quantity drops to certain value, and PoE system main power source module fails normal power supply, so MCU microcontroller is according to the priority level of outer source device, stops the outer source device low to priority to power, and only allows the outer source device work that priority level is high.
Execution mode three
If find main power source energy normal power supply, whether MUC micro controller module needs charging if first detecting batteries module, if need charging, so MUC microcontroller communicates with PoE system module, first calculate outer source device power demand, if PoE system main power source module also has dump power, then regulate the size of charging current according to the dump power of PoE system main power source module, control DC/DC reduction voltage circuit module and charging circuit module work, accumulators group is charged; If electrical power quota required for outer source device, do not have unnecessary electrical power accumulators group to charge, so batteries wouldn't be charged, until MUC has detected that unnecessary electrical power is chargeable.If batteries module does not need charging, so PoE switch main power source module only need be powered to outer source device.
Two values are provided with for the discharge and recharge of batteries module in MUC microcontroller, be respectively batteries module maximum and batteries module minimum value, when batteries module is charged, when MUC microcontroller detects that the electricity of batteries is more than or equal to maximum, charging will be stopped; During the charging of batteries module, when MUC microcontroller detects that the electricity of batteries is less than or equal to minimum value, electric discharge will be stopped.In charge and discharge process really, the discharge and recharge of MUC microcontroller time monitoring batteries, makes batteries discharge and recharge within reason, extends the service life of batteries.
By reference to the accompanying drawings the preferred embodiment of the utility model and embodiment are elaborated above, but the utility model is not limited to the above-described embodiment and examples, in the ken that those skilled in the art possess, various change can also be made without departing from the concept of the premise utility.
