Description
Technical field
The present invention relates to a kind of power supply remote management technologies, antitheft more particularly, to a kind of shared electric automobile charging pile
The long-range control method for filling/sneaking current and shared automobile charging pile remote power supply management system.
Background technique
With the rise of shared theory, after shared bicycle, shares electric car and also risen in various regions.Shared electric car makes
With convenient, because its economy and practicability receive the generally approval of user；And because of its environmental protection, energy conservation, it is increasingly becoming political affairs at different levels
The Green Travel vehicles that mansion is promoted.As the market of shared electric car is increasing；It is each for electric automobile charging pile
The demand of kind technology is also following.Electric automobile charging pile is mostly in unattended state at present, this is just needed pair
It carries out intelligentized unattended.And it is a wherein important part that intelligence is anti-theft.
Existing charging pile anti-theft power technology is all the switch that only charging pile itself controls power supply, and administrative staff can not
The power supply of charging pile is controlled by remote terminal.Thus trouble, and technical staff are brought to the upgrading debugging of charging pile
The state that charging pile can not be grasped in real time is unfavorable for finding loophole.There are no rigorous, mature electric cars currently on the market
Charging pile intelligence anti-theft power technology, seriously compromises the interests of industry associated merchant, limits the hair of industry to a certain extent
Exhibition.
In view of this situation, if it is possible to a kind of scientific and effective intelligent anti-theft power technology be provided, can be necessarily shared electricity

There is special JSON formatted data processing method）, for being compatible with reasonable error between vehicle position information and charging pile position
（60 meters are defined as, because charging pile and vehicle location can not be just the same, and positioning also has error）, when charging pile and vehicle
Location error within the specified scope when, the JSON formatted data of two positions is revised as the same by we；
Position comparison program：If by JSON data calibration program treated vehicle position information and charging pile location information phase
Together（Allow certain error）, then relay is connected, then enters power supply local control circuit, otherwise refusal charging.
Each module workflow：
Order license plate and location information：According to user in user interface（UI）The order license plate of upper input, charging pile is by license plate number
It is sent to background server by communication module, inquiry obtains vehicle and charging pile position letter after server receives license plate number
Breath, using position comparison module comparison position information, remote power supply management terminal control relay 1 is connected if they are the same, then into
Enter charging pile power supply local management module, relay 1 is controlled by charging pile power supply remote supervision module if different and is disconnected, is closed
Charging pile charging circuit power supply is closed, forbids charging.
Into charging pile power supply local management module：If the letter that electric signal generating mechanism and electric signal receiving mechanism receive
Number consistent, then power supply local control circuit control relay 2 is connected in charging pile, and power supply line is connected, allows to charge, otherwise
Other vehicles do not install corresponding electric signal generating mechanism, and the signal that the electric signal receiving mechanism on charging pile receives is different,
