In the technical field of the existing charging equipment, a floor type charging pile is more common in outdoor public large-scale public places; a large number of floor type charging piles directly communicated by an input end and a three-phase alternating current power grid are built, and under severe weather conditions and when the operation is considered improper, leakage accidents easily occur, and great threats are brought to life and property safety of people.

The current electric pile that fills generally disposes anticreep protection switch, and its inside anticreep detection module that is equipped with, when the electric leakage condition takes place, anticreep protection switch disconnection circuit is in order to ensure user's safety. However, the anti-creeping protection switch needs to be manually pressed regularly (generally for one month) to check whether the anti-creeping protection switch is in a normal working state, which brings a certain workload to managers and is easy to forget, and if the anti-creeping protection switch is damaged and cannot be found in time, potential safety hazards are left.

Detailed Description

The details of the present invention will be described below with reference to the accompanying drawings and examples.

As shown in the attached figure 1, the invention provides an anti-leakage system of a charging pile, which comprises a power supply module, a leakage detection module, an analog leakage module, a first control module, a signal processing module, a first communication module, a mobile terminal, an alarm mechanism, an execution mechanism, a second communication module and an upper computer, wherein the output end of the power supply module is connected with the input end of the first control module, the output end of the analog leakage module is connected with the input end of the leakage detection module, the output end of the leakage detection module is connected with the input end of the signal processing module, the output end of the signal processing module is connected with the input end of the first control module through the input end of the first communication module, the output end of the first control module is connected with the input ends of the alarm mechanism, the execution mechanism and the mobile terminal, the output end of the first control module is connected with the input end of the second communication module, the output, the upper computer is internally provided with a data analysis module and a charging pile information database.

Charging pile batch information, sales information, buyer information and use duration information are recorded in the charging pile information database.

The first control module is a single chip microcomputer.

The electric leakage detection module comprises a zero sequence current transformer and a divider resistor. When the zero sequence grounding current is generated by the power system, the zero sequence current transformer is matched with a relay protection device or a signal for use, so that the device element acts, and the protection or the monitoring is realized. When electric shock or leakage fault occurs in the circuit, the secondary side of the mutual inductor outputs zero sequence current to make the equipment on the secondary circuit protective (power cut, alarm, etc.)

The signal processing module comprises an amplifying circuit and a converting circuit. The signal processing module is responsible for amplifying the signal transmitted by the electric leakage detection module and converting the electric signal into a digital signal so as to be processed by the single chip microcomputer.

The actuating mechanism is a release. When the first control module receives the leakage information, the first control module controls the actuating mechanism (in this embodiment, the release) to cut off the power supply to the charging pile, and the first control module also controls the alarm mechanism to alarm. The alarm mechanism can be in the form of light or sound and the like, and reminds a user of paying attention to danger. The mobile terminal may be a computer in a duty room.

The simulation electric leakage module comprises a simulation electric leakage signal generating circuit and an electromagnetic valve, the electromagnetic valve is connected between the electric leakage signal generating circuit and the input end of the electric leakage detection module, and a timing unit is arranged in the first control module and used for timing to close the electromagnetic valve regularly. The first control module controls the electromagnetic valve to be opened at fixed time so as to connect the simulation electric leakage information generating circuit with the electric leakage detection module, and the test is generally carried out once a month. Under the normal condition, after the solenoid valve opened, the electric leakage detection module can detect electric leakage information and feed back to first control module, if the electric leakage detection module work is unusual, then first control module can not receive the information that comes from the electric leakage detection module, and at this moment, first control module also can send a signal to mobile terminal, reminds charging pile managers electric leakage detection module to break down. Under the non-simulation state, if the electric leakage occurs, the electric leakage detection module in normal work sends a signal to the first control module, and the first control module controls the action of the actuating mechanism to complete the power failure of the charging pile. (the first control module judges whether the leakage is simulated or actual leakage through the opening state of the electromagnetic valve so as to determine whether the release needs to be opened to complete the power failure)

The data analysis module comprises analysis logic, wherein A, the service time information of the plurality of charging piles is obtained, B, the leakage frequency information of the plurality of charging piles is obtained, C, the ratio alpha of the leakage times of the charging piles to the service time is calculated, D, alpha is arranged according to the size sequence in a descending order, and E, the charging piles 30% of the alpha before the alpha arrangement are analyzed to judge whether the charging piles belong to the same batch and are sold to the same area.

If the charging piles with frequent electric leakage are concentrated in batches, the production process can be traced, specific reasons can be known, and the product quality can be improved. If the areas are concentrated, charging piles which meet the requirements better can be designed according to local climates. If the regional performance or the batch performance is not obvious, the users are instructed to use and maintain, and the occurrence of electric leakage is reduced.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
