15, C-RAN distributed spider web indoor power supply miniature alternating current-direct current master slave switch on-chip power auxiliary centre C-RAN spider web accumulator cell charging and discharging balanced management module stops charging.Each principal and subordinate No. 1 high-power magnetic relay closedown departs from and central C-RAN spider web is powered installs the connection of total plumbic acid/lithium electric electric power storage group energy supply system concentratedly.
Preferably, the method that the present embodiment provides also can comprise following process:
The interchange provided when the indoor spider web merged for four nets has a power failure, and when the battery capacity of energy supply system has fallen specified volume, the operating voltage of high-power magnetic relay is reduced to guarantee voltage value; Guarantee the power supply of convergence type spider web, adopt half mode to power to enclosed type and divergence form spider web.
Such as: shown in composition graphs 1, this process is specifically as follows:
Monitoring module is under interchange power-off condition.Battery capacity reduces 30-60%.Take following steps to ensure power supply.
The magnitude of voltage that monitoring module sets No. 4 minimum work of high-power magnetic relay is 40v.Ensure that continuous service C-RAN spider web when battery discharging to work long hours requirement for the balanced sending module maximizing of Electrodynamic balance.
Monitoring module control C-RAN spider web convergence type, enclosed type, the three-in-one output control module of divergence form.Guarantee the power supply guarantee of convergence type spider web.Powering to enclosed type, divergence form spider web adopts semi-load modes to power.
Monitoring module control continuous service C-RAN spider web carries out spider web for the supply power voltage that the balanced sending/receiving module of Electrodynamic balance improves the first secondary direct current cables optoelectronic composite cable short distance core balanced power supply network to 55v and powers.
Monitoring module controls non-continuous operation distributed group net mode spider web distributed intelligence and divides distribution output control unit to carry out the preparation of second load.
Monitoring module is monitored the first secondary spider web supply power voltage by signal processing module and is improved rear mixed type different electric pressure batteries output control module, terminal voltage situation of change during battery discharging.
Preferably, the master/slave Switching Power Supply of the miniature alternating current-direct current of the distributed spider web of the C-RAN in the present embodiment indoor power supply can also judge certain primary or from using Switching Power Supply fault, exist side by side and depart from the function of spider web by it.
Because under normal circumstances C-RAN distributed spider web indoor power supply miniature alternating current-direct current master slave switch power-supply device be separately responsible for institute the one two three level Four spider web is powered.Spider web for Electrodynamic balance balanced sending/receiving module (being equivalent to dynamic equalization transceiver module) E F A B C D(with reference to shown in Fig. 3) carry out the monitoring of principal and subordinate's electric power outputting current voltage.And wireless Parallel Control is carried out to principal and subordinate's power work I/O mode.
When a certain two or three level Four spider web loads strengthen, principal and subordinate's power-supply device output current can be caused to strengthen (the main >0 of △ I, △ I is from C district >0, △ I is from B district >0, △ I is from D district >0), and output voltage reduces (the main <0 of △ V, △ V is from C district <0, △ V is from B district <0, △ V is from D district <0) product of the changing value of voltage and electric current is load (△ I master+△ I is from C district+△ I from B district+△ I from D district) × (△ V master+△ V is from C district+△ V from B district+△ V from D district) <0.
When a certain two or three level Four spider web loads reduce, principal and subordinate's power-supply device output current can be caused to reduce (the main <0 of △ I, △ I is from C district <0, △ I is from B district <0, △ I is from D district <0), and output voltage raises (the main >0 of △ V, △ V is from C district >0, △ V is from B district >0, △ V is from D district >0) product of the changing value of voltage and electric current is negative (△ I master+△ I is from C district+△ I from B district+△ I from D district) × (△ V master+△ V is from C district+△ V from B district+△ V from D district) <0.
When a certain two or three level Four spider web principal and subordinate power-supply devices break down, the output voltage of this principal and subordinate's power-supply device can raise or reduce, electric current is caused to raise equally or reduce, i.e. (△ IE+ △ IF+ △ IC+ △ ID) × (△ VE+ △ VF+ △ VC+ △ VD) >0.Due to
△IE=△IC+△ID
△IF=△IA+△IB
Therefore the input and output electric current in the indoor spider web merged in each network and voltage is netted by monitoring four, and according to the change of input and output electric current and voltage, namely the positive and negative of (△ IE+ △ IF+ △ IC+ △ ID) × (△ VE+ △ VF+ △ VC+ △ VD) is analyzed, for Electrodynamic balance balanced sending/receiving module E F A B C D, spider web can judge whether whether principal and subordinate's power supply normally works, and take treatment measures immediately.By contrast, such scheme has the connection do not needed between spider web principal and subordinate power-supply device, reduces failure rate, and the equal independent operating of one two three level Four spider web principal and subordinate power-supply device, shows as the technique effect without master slave relation simultaneously.
Present embodiments provide a kind of implementation method being applicable to the lower distributed indoor spider web power supply of four net fusions, in the method, C-RAN distributed spider web indoor power supply miniature alternating current-direct current main switch power supply can all devices in supervisory and control system, can when energy supply system fault, when meeting each network and equipment is powered, storage battery is charged, and self-diagnostic function is powerful, and first carry out big current by auxiliary centre C-RAN spider web storage battery elasticity charge and discharge balancing administration module and increase progressively to solve to overlap principal and subordinate's power supply principal and subordinate battery charging current limiter function with the self adaptation elasticity charging modes that successively decreases more, and battery is to the equal flow problem of the problem of filling and multisystem, achieve when electrical network no-voltage, system communication is powered by central C-RAN spider web and is installed the technique effect that total plumbic acid/lithium electricity electric power storage group energy supply system still normally works concentratedly.
