With reference to Fig. 2, the embodiment of the present invention also provides a kind of circuit breaking controlling method, applied to above-mentioned power-off control system 100.
The idiographic flow and step shown in Fig. 2 will be described in detail below.
Step S110, information read device 120 reads the identity information stored in information-storing device 110 and account gold
Volume.
Step S120, power-down control device 130 obtains the identity information and account gold that described information reading device 120 is read
The account amount of money is simultaneously compared by volume with the first preset cost and the second preset cost that prestore respectively, in account gold
To the transmit power Regulate signal of PCU Power Conditioning Unit 140 when volume is less than the first preset cost, it is less than second in the account amount of money
During preset cost power down control signal is sent to cut-off switch 150.
Step S130, the PCU Power Conditioning Unit 140 according to the power regulating signals reduce the electric power system to
The output power at family.
Step S140, the cut-off switch 150 is according to the power down control signal in the preset time cut-out power supply system
The power supply united to user.
Alternatively, the specific implementation of the control method shown in step S140 can have a variety of.In the present embodiment, it is
There is misoperation in cut-off switch 150 when avoiding the power-down control device 130 from erroneous judgement occur, so as to cause improper power-off
Problem, the step S140 step that implements is：The power-down control device 130 obtains current again in the preset time
Account amount of money, if the account amount of money be less than second preset cost, to the cut-off switch 150 send determine power-off indicate
Signal；The cut-off switch 150 determines that powering off indication signal and the power down control signal cut-out power supply is according to described
The power supply united to user.By above-mentioned design, the cut-off switch 150 only receive at the same time the power down control signal and
During the determination power-off indication signal, power supply of the electric power system to user could be cut off, it is to avoid because the account amount of money is big
When the second preset cost power down control signal is sent after the erroneous judgement of power-down control device 130 to the cut-off switch 150
And cause the problem of wrong diagnosis is electric.
Further, in the present embodiment, methods described can also comprise the following steps, below in conjunction with Fig. 3 to step
S150 and step S160 are described in detail.
Step S150, the power-down control device 130 is less than first preset cost, more than institute in the account amount of money
When stating the second preset cost, first preset cost and the difference of current account amount of money are calculated at interval of preset duration, and
Different power regulating signals are sent to the PCU Power Conditioning Unit 140 according to amplitude difference of different sizes.
Step S160, the PCU Power Conditioning Unit 140 is according to the different power regulating signals control power supply system
The reduction amplitude united to the output power of user.
Pass through step S150 and step S160, it is possible to achieve according to the numerical value of different account amount of money, control electric power system
Different output powers are exported to user, the intelligent and reliability of the power-off control system 100 on the one hand can be improved, separately
On the one hand it can also play a part of reminding user account insufficient in amount, further increase the power-off control system 100
Practicality.

S170 and step S180 are described in detail
Step S170, the power-down control device 130 is when the account amount of money is less than first preset cost to institute
State the first alarm lamp and send the first enabling signal, when the account amount of money is less than second preset cost to described the
Two alarm lamps send the second enabling signal.
Step S180, first alarm lamp is according to the first enabling signal startup work, second alarm
Indicator lamp is according to the second enabling signal startup work.
Pass through step S170 and step S180, it is possible to achieve to first alarm lamp and the second alarm lamp
Control, so as to realize the instruction of the state to current account amount of money.
Further, in the present embodiment, methods described can also comprise the following steps, below in conjunction with Fig. 5 to step
S190 and step S200 are described in detail.
Step S190, the power-down control device 130 is when the account amount of money is less than first preset cost to institute
State communicator 170 send power-off pre-warning signal, when the account amount of money is less than second preset cost to the communication
Device 170 sends power-down notice signal.
Step S200, it is pre- that the communicator 170 sends power-off according to the power-off pre-warning signal to user communication device
Alert information, power-down notice information to user communication device sent according to the power-down notice signal.
By step S190 and step S200, user can be made to obtain current account amount of money in time by communication equipment
State and whether power off, to remind the timely paying of user, it is ensured that the continuity of electricity consumption.
In summary, the present invention is provided a kind of power-off control system 100 and method, by setting PCU Power Conditioning Unit
140, when the account amount of money of user is less than the first preset cost, reduce electric power system to the output power of user to limit user
High-power electric appliance equipment is used in the case where account amount of money is not enough, so as to solve because the use of powerful device causes extremely short
The problem of account amount of money exceedes the overdraw amount of money and causes power-off in time.Secondly, by setting communicator 170, it will can break
Electric warning information and power-down notice information sends to user to point out user to pay correlative charges in time in time, it is to avoid because of power-off
And influence the problem of user normally lives.
