Specific embodiment
The present invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
It is illustrated in figure 1 embodiment of the present invention electrical schematic.The present invention proposes a kind of self-powered distributed intelligence distribution The operation method of terminal.Which installs current transformer, the electric energy input power management module of acquisition, power management on main inlet wire Module is connected with energy-storage battery, Intelligent power distribution terminal and Yun Hua data centers respectively, and Intelligent power distribution terminal is located in ring main unit, is used In sampling ring main unit in electric signal and send to Yun Hua data centers.
The operation method of the present embodiment distribution terminal is as follows:
S1, when main inlet wire has electricity, the electric energy from current transformer is directly supplied to Intelligent power distribution terminal and Yun Hua data centers Electricity, while charging to energy-storage battery, now, Intelligent power distribution terminal carries out data acquisition with routine sampling frequency, with Conventional Time Interval carries out data upload;
S2, when main inlet wire is without electricity, then Intelligent power distribution terminal and Yun Hua data centers are powered by energy-storage battery;Power management mould Block monitors the voltage of energy-storage battery, if the voltage of energy-storage battery is not less than predetermined threshold value V1, Intelligent power distribution terminal is adopted with conventional Sample frequency carries out data acquisition, carries out data upload with regular time intervals;If the voltage of energy-storage battery is less than predetermined threshold value V1 And being not less than given threshold V0, then Intelligent power distribution terminal carries out data acquisition with sample frequency f1, enters line number with time interval t1 According to upload;f1 <Routine sampling frequency, t1>Regular time intervals;When the voltage of energy-storage battery is less than given threshold V0, intelligence Distribution terminal and Yun Hua data centers enter resting state;When main inlet wire recovers to have electricity, in Intelligent power distribution terminal and cloud data The heart is waken up, and performs according to step S1.
As shown in Fig. 2 the power management module circuit theory diagrams of the present embodiment, power management module has what is be sequentially connected Rectifier bridge(Diode D1-D4 is constituted), filter circuit of pressure-stabilizing(It is made up of voltage stabilizing chip U, resistance R1, R2 and electric capacity C1, C2)With Power switching circuit.Rectification circuit(Rectifier bridge)Circuit common is with filter circuit of pressure-stabilizing, the present embodiment is not carried out specifically It is bright.Power switching circuit includes a diode D5, and the positive pole of diode D5 connects the output end of filter circuit of pressure-stabilizing, diode The negative pole of D5 connects the positive pole of energy-storage battery and DTU feeder ears respectively.When the output voltage of filter circuit of pressure-stabilizing is higher than accumulation of energy electricity Cell voltage, then assert that leader cable has electricity, and now diode D5 conductings, the electric energy that current transformer is obtained are supplied to Intelligent power distribution terminal Electricity, while being charged to energy-storage battery;When the output voltage of filter circuit of pressure-stabilizing is less than energy-storage battery voltage, then main electricity is assert Cable without electricity, powered by energy-storage battery by now diode D5 ON-OFFs, Intelligent power distribution terminal.
Intelligent power distribution terminal feeder ear is connected with for measuring the CPU of its voltage, and according to the voltage-regulation intelligence for measuring The time interval that the data sampling frequency and data of energy distribution terminal is uploaded.
In the present embodiment, CPU is by monitoring the voltage of Intelligent power distribution terminal feeder ear come adjusting working mode.When main inlet wire Just during power-off, it is assumed that now energy-storage battery electricity is sufficient, voltage is located near rated voltage Ve, the magnitude of voltage that CPU is detected More than predetermined threshold value V1, now, the mode of operation of Intelligent power distribution terminal does not change(Data acquisition is carried out with routine sampling frequency, Data upload is carried out with regular time intervals), only when battery electric quantity declines to a certain extent(The voltage for detecting is less than V1), Just change the mode of operation of Intelligent power distribution terminal, reduce the power consumption of Intelligent power distribution terminal.Such way can be avoided due to short Intelligent power distribution terminal mode of operation frequent switching caused by time power-off, improves the stability of system.And for the long period Power-off, the system can extend the effective time of Intelligent power distribution terminal again so that the electric number of ring main unit during long time electric supply failure According to still being obtained by data center.
Certain ring main unit originally adopts S1 working methods, in main inlet wire using as above self-powered distributed intelligence distribution terminal After power failure, still with sampling per second once and by cloud terminal upload information, DTU is entered the 7AH batteries for being adopted after 7 hours Resting state.After main inlet wire has a power failure, if using S2 working methods, battery electric quantity to drop to certain level, sample frequency is set It is set to sampling per minute and uploads information once.Jing DTU power consumption calculations, in this example, DTU can be in 7AH battery electric power thus supplieds Under work on 10 hours.In this example, the DTU before terminating that had a power failure at 8 hours never has dormancy, and control centre remains able to To information, the state of the ring main unit is understood in time.
In addition to the implementation, the present invention can also have other embodiment.All employing equivalents or equivalent transformation shape Into technical scheme, all fall within the protection domain of application claims.
