Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, technical scheme is described further.
Embodiment
If Fig. 1 is the system block diagram that wireless router is powered.
Being powered by 12V power module 101 on the router of this embodiment, 12V is divided into by DC-DC module 102,103
Two-way, a road give route master chip MTK7628NN module 105, a road is given to the LTE modem mould of Marvell 88MP1802
It (is 1A, DC-DC in view of MTK7628NN and Marvell 88MP1802 peak inrush current in application scenarios that block 106 is powered
Selecting silicon Cenda SY8120B1 model, output electric current is 2A).In figure, stand-by power supply apparatus module 104 just relates to router
Stand-by power supply device.
Such as the system block diagram that Fig. 2 is wireless router stand-by power supply device.
Stand-by power supply module 104 is made up of 3 parts, standby power supply module 201, hardware control module 202, and software controls mould
Block 203.
Standby power supply module 201 uses two super farad capacitor (running voltages of Marvell 88MP1802 connected
For 4V, select triumphant U.S. electric capacity: specification 2.7V/10F is connected), need during capacitances in series to consider " the passive balance of voltage " problem.By galvanic electricity
Pressure balanced voltage available distribution resistance realization (Fig. 4: R6=R7=5.4K) in parallel with each super farad capacitor, this can allow electricity
Stream from high-tension super farad capacitor on the super farad capacitor of indwelling low-voltage thus realize the balance of voltage, so balance
The flowing with the offer higher electric current of super farad capacitor that selects of resistance does not increase the leakage current (root of super farad capacitor
According to maximum operation (service) temperature selection parallel resistance: 3.3K Ω---22K Ω).
The break-make that hardware control module 202 controls metal-oxide-semiconductor by bleeder circuit opens or closes stand-by power supply.Dividing potential drop electricity
Road 1 select 12V external power supply come dividing potential drop can as detecting 12V power supply determine whether to the most in place open stand-by power supply,
Partial pressure value need to meet metal-oxide-semiconductor conducting voltage requirement simultaneously.
Software control module 203 comprises initialization section, sample detecting part, switching control section and notification module.Just
In stage beginning, sampling input interface (GPIO35) is high level, and CPU detects the level state of input interface in real time, when level draws
Then judge external 12V power cut-off after low, start notification module notice base station external power supply 12V power-off, can take out stitches.
Such as Fig. 3,4 be stand-by power supply and the circuit diagram of hardware control module of stand-by power supply device
12V power supply is powered to wireless router, and 12V power supply is turned by DC-DC1 102, DC-DC2 103 (SY8120B1)
Becoming 3.3V (MTK7628NN 105) side to power, 4V powers to Marvell (88,MP1,802 106) side, completes start process, configuration
Sampling input interface (GPIO35) is pulled to 1.8V high level.
In standby power supply module 201, C1, C2 are that super farad capacitor (2.7V/10F) is by R2, R3 (super farad capacitor
Charging current can be more than 2A, current limliting problem to be considered charging when) path implement charging, R1 (0805-0 Ω) is normal system
System supply path.
After 12V power cut-off, bleeder circuit 1 detects 12V power cut-off, opens ON-OFF control circuit p-type metal-oxide-semiconductor T1
(after power-off, partial pressure value reduces to low level, therefore selects p-type metal-oxide-semiconductor: WPM2341-3/TR), stand-by power supply starts to 88MP1802 side
System power supply is provided.Bleeder circuit 2 detects 12V power cut-off simultaneously, and output low level gives sampling input interface (GPIO35),
CPU detect sampling input interface (GPIO35) by high step-down, now software judges external 12V power cut-off, proceeds by and is
System state backup, and send instructions to base station, wireless router starts shutdown process, it is achieved normally roll off the production line.
Being described in detail the specific embodiment of the present invention above, but it is only used as example, the present invention is not limiting as
In particular embodiments described above.To those skilled in the art, any equivalent modifications that this invention is carried out and
Substitute the most all among scope of the invention.Therefore, the impartial conversion made without departing from the spirit and scope of the invention and
Amendment, all should contain within the scope of the invention.
