Automobile charging pile has been widely used.
Simultaneously with the popularization and popularization of charging pile, substantial amounts of unattended charging pile also turns into a kind of development and becomes
Gesture, this charging pile is charged by customer self-service, without professional operator's Site Service, when being greatly saved operation maintenance
Cost of labor.The electric motor car charging service that charging pile is provided convenience for people, while also triggered to its safe concern, especially
It is personal safety.
Most of charging pile in the market for convenience of wiring and device layout, by rectification module, the band such as main switch
The cell arrangement of high-tension electricity, once the big rainy day has ponding to cover rack inlet and outlet, floods in rack proximity from the ground
High tension apparatus in low level, the water around pile body will be powered, and this is abnormally dangerous for charging person and passer-by.
This risk is apparently more protruded on unattended charging pile.
Utility model content
It is the shortcoming for overcoming above-mentioned prior art in the purpose of this utility model, there is provided a kind of safe electronic vapour
A kind of waterproof charging pile of car.
The utility model includes main switch, input contactor, output contactor, charging inlet and control unit, the master
Switch, input contactor, output contactor and charging inlet are sequentially connected in series；The signal output part of control unit connects input respectively
Contactor and output contactor, for opening and shut-off for control input contactor and output contactor；It is characterized in that：In control
One signal input part connection level sensor of unit processed.
Level sensor exports a safety signal and is given to charging control unit under normal circumstances, and charging pile is normally used.
When charging pile occurs water logging and exceedes default critical value, level sensor transmits a signal to control unit, control unit
Start the power contacts of responsive measures, cut-out input contactor and output contactor, cause charging to terminate, so as to ensure charging people
Member and the personal safety of surrounding people, it is to avoid the danger of contact.The utility model can ensure charging personnel and surrounding pedestrian
Personal safety, it is to avoid the further expansion of accident, to greatest extent reduce charging pile equipment damage.
Further, in order to notify background monitoring system in time, maintenance personal is sent to be processed in time, the control is single
Unit is also connected with background monitoring system, it is also possible to be connected with background monitoring system by holding wire or wireless network, monitoring system
Monitor the mode of operation of charging pile.
In addition for direct-current charging post, described control unit connection rectification module group, the rectification module group concatenation
Between input contactor and output contactor.
Brief description of the drawings
Fig. 1 is the system block diagram of the charging pile of the utility model embodiment 1.
Fig. 2 is the system block diagram of the charging pile of the utility model embodiment 2.
Fig. 3 is the workflow diagram of the utility model charging pile.
Specific embodiment
Embodiment 1：
As shown in figure 1, charging pile 200 is main being connect by main switch 201, input contactor 202, rectification module group 203, output
Tentaculum 204, charging inlet 205, control unit 206 and level sensor 207 are constituted.
Main switch 201, input contactor 202, rectification module 203, output contactor 204 and charging inlet are by cable or electricity
Line is sequentially connected in series.
Control unit 206 respectively with input contactor 202, between output contactor 204, rectification module 203 pass through signal
Line communicates with one another connection.
Level sensor 207 connects control unit 206 by signal output part, there is provided water level signal.
Level sensor 207 can be exported the sensor of continuous water level read signal, or export with switching value
Or switching value combination represent water level signal sensor, or it is other types of can provide analog quantity or switching value letter
Processed number for control panel acquisition testing and by known technology and be calculated the sensor of water level information.
Water level signal of the present utility model can arrange two groups, i.e. the first critical value water level signal and the second critical value water level
Signal, the first critical value water level signal collection point is located at the second critical value water level signal lower section.When water level first exceedes from low to high
First critical value, shows that rack starts water inlet, and control unit 206 detects water level signal and is more than the by level sensor 207
During one critical value, i.e., complete charge and the power contacts of output contactor 204 are disconnected, be mainly guarantor and the peace of vehicle
Entirely.
If water level continues to go up, and more than the second critical value, shows that rack has been in serious Riddled Condition, it is necessary to vertical
Input contactor is disconnected, the safety of people, vehicle and charging pile is further protected, then control disconnects the electricity of input contactor 202
Power is contacted.
Embodiment 2：
As shown in Fig. 2 other classes ibid example, simply, the control unit 306 of charging pile 300 passes through wired or channel radio
The mode of news is connected to background monitoring system 310.
Charging pile 300 can be connected with background monitoring system 310, and server is configured to monitor the operation shape of charging pile
State.One skilled in the art will appreciate that charging pile can be connected to background server by way of wired or wireless telecommunications, pipe
Reason person can easily monitor the state of charging pile by means of remote monitoring.If there is the failures, charging station such as immersion in charging pile
Supplier can rapidly send maintenance personal to safeguard charging pile.
Fig. 3 shows the utility model charging pile testing process, and method 400 mainly comprises the following steps：
Step 401, detects the water level signal of charging pile.Control unit obtains the straight of level sensor offer by holding wire
Connect water level signal or obtain water level signal by level sensor sampling primary signal and by known technology treatment.
Step 402, water level signal is compared with the first critical value, if water level is more than the first critical value, performs step
403, otherwise perform step 404.
Step 403, when water level is more than the first critical value, stops charging and disconnecting the power contacts of output contactor.
Step 405 is performed simultaneously continues sensed water level.
Step 404, when water level is less than the first critical value, it is allowed to which charging pile is charged normal to electric motor car, Ran Houjin
Enter circulation step 401, continue sensed water level.
Step 405, sensed water level signal similar to step 401.
Step 406, water level signal is compared with the second critical value, if water level is more than the second critical value, performs step
407, otherwise perform step 405.
Step 407, when water level is more than the second critical value, disconnects the power contacts of input contactor.
The level sensor of the waterproof charging pile that the utility model is provided is used for sensed water level signal；Once testing result surpasses
Default critical value is crossed, charging pile according to circumstances takes appropriate measures complete charge until the electric power for disconnecting input contactor connects
Touch, therefore the protection customer of the charging pile with sensor or passerby are occurring to exempt from electric shock in the case that charging pile soaks.
The anti-water enchroachment (invasion) charging pile and its detection method provided according to the utility model, it is very square for charging station provider
Just the state of remote monitoring charging pile and real-time servicing these charging piles.
Compared to prior art, whether the utility model can detect and judge charging pile in water logging state, and root
It is judged that the timely charge closing stake power supply of result, protection user and operating personnel exempt from Danger Electric shock risk.And, it is easy to charging station remote
Range monitoring charging pile state and real-time servicing.
