Utility model content
The utility model is in order to solve the above-mentioned technical problem, and it is an object of the present invention to provide a kind of charging pile detection based on NB-IOT
System.
The utility model is achieved through the following technical solutions:
A kind of charging pile detection system based on NB-IOT, including socket, the socket include jack body, the socket
Ontology is cylindrical structure, forms platform at the top of jack body, the jack to lower recess is provided on platform；Further include with
The plug that socket matches, the plug include header body, and the header body is cylindrical structure, at the top of header body
Form platform；The outer diameter of the jack body is matched with the internal diameter of header body so that not shaking after header body insertion jack body
It is dynamic；The inside of the upside of the header body is object placing cavity；Lockable mechanism is additionally provided in object placing cavity, lockable mechanism includes inserting
The bottom of object placing cavity is arranged in pin, communication receipt module, drive module, connecting band and storage through-hole, storage through-hole；Bolt is set
It sets in the side of storage through-hole, bolt includes latch body, shaft perforation and shaft, and the latch body is box structure, institute
The side that latch body is arranged in shaft perforation is stated, the inside of shaft perforation is arranged in the shaft and shaft and shaft perforate it
Between do not produce relative sliding, shaft perforation the hollow partial denudation for making shaft in middle part outside；The both ends of shaft are fixed on storage
The two sides of through-hole；The connecting band is in ring-band shape, and one end of connecting band bypasses the exposed part of shaft, connecting band it is another
End bypasses the rotating bar of drive module, does not generate sliding between shaft and connecting band, slides the rotating bar and connection of drive module
Sliding is not generated between band；The communication receipt module is unidirectionally connect with drive module communication；The rotating bar of drive module rotates

It receives in through-hole or discharges latch body from storage through-hole, in the jack of the latch body insertion jack body after release.
In the prior art, charging pile can't support hot plug, and the charging voltage of charging pile is very high, if hot plugging
It is easy to that the battery of human body, charging pile equipment, electric car is damaged or damaged, user's hot plugging in order to prevent is filled
Electric rifle locks plug and socket using electromagnetic lock, although can be realized using electromagnetic lock prevents hot plug, electromagnetism
The service life of lock is short, access times and its limited, so that the frequent replacement of electromagnetic lock and the frequent maintenance of charging pile, are caused
The raising of charging pile maintenance cost and maintenance cost, simultaneously as it is all to pass through people that the maintenance and maintenance of charging pile are most of
The case where work detects realization, and artificial detection inevitably will appear missing inspection, accidentally subtract, so that it is hidden that charging pile still remains safety
Suffer from.The utility model avoids the generation of the above problem using the structure of electromechanical.Charging gun is often arranged in charging plug
On, charging socket is arranged on the car body, and the side of car body is generally arranged in charging socket, when on charging plug insertion charging socket
When, since with line, its gravity forces charging plug to have the tendency that slide downward to charging plug, if charging plug and charging
Occur connecting untight situation between socket, often at a distance from the separation of the upper end of the upper end and charging socket of charging plug
It is bigger, therefore, object placing cavity is set in the header body upper end of charging plug, lockable mechanism, lockable mechanism are set in object placing cavity
It include bolt, communication receipt module, drive module, connecting band and storage through-hole including lockable mechanism, storage through-hole setting exists
The downside of object placing cavity, for putting bolt, connecting band is connected between shaft and drive module storage through-hole, when drive module is driven
Drive shaft when moving its rotating bar, shaft drives latch body to rotate in storage through-hole, and drive module whether rotate be by
Communication receipt module control, communication receiving module with charging system by wirelessly connecting, when charging system is starting to charge it
Afterwards, communication receiving module is switched on drive module driving bolt and discharges from storage through-hole, and the bolt after release falls into socket sheet
In jack on the upside of body, during charging system persistently charges, bolt will not be withdrawn into storage through-hole, wait fill
After electric system charges, communication receipt module receives signal and bolt is recovered in storage through-hole by drive module again, from
And the case where socket and plug is separated, avoids the plug plug under energized state in this way generation.
Further, the surface of the exposed part of shaft, the inner surface of connecting band, drive module rotating bar surface
It is provided with protrusion.
By the way that protrusion is arranged, make the frictional force between shaft and connecting band, between the rotating bar and connecting band of drive module
Increase, prevents between shaft and connecting band, generates sliding between the rotating bar and connecting band of drive module, lose the control to bolt
Production is used.
Further, communication receipt module uses the communication module based on MDM9206.MDM9206 belongs to NB-IOT chip,
The advantages of NB-IOT chip, is cheap, and occupied bandwidth is low, is not take up normal communication channel.
Further, drive module uses micromotor.The small volume of bolt is enough to control bolt using micromotor
Movement.
Further, the quantitative range of lockable mechanism is 1~5.The quantity of lockable mechanism is more, between socket and plug
Locking effect it is better, can be improved safety.
The utility model compared with prior art, has the following advantages and benefits: the utility model is on plug
Lockable mechanism is set, jack is set on socket, avoids charging gun the case where charging in such a way that bolt is inserted into jack
Lower plug, avoids security risk；Charged state is understood by using communication receipt module connection charging system simultaneously, thus logical
Module of overdriving controls the release and withdrawal of bolt, simple, convenient, fast, safe.
