Referring to fig. 1 to 9, an embodiment of the present invention provides a charging gun plugging stability monitoring system, which can monitor a plugging compactness of a charging gun in a fixing seat, ensure a stability of the charging gun after being fixed, and solve a practical situation that the plugging of the charging gun is incomplete or loose.
Rifle that charges grafting stability monitoring system fills electric pile simulator as attaching the main part to and set up at the inside monitoring circuit 100 that fills electric pile simulator. Fill electric pile simulator main part and be the electric pile simulator among the prior art, it includes outside casing 200, is provided with fixing base 300 on the casing 200, can insert the rifle 400 that charges in the fixing base 300.
The monitoring circuit 100 includes a monitoring module 101, a control module 102, and an indication module 103. The monitoring module 101 is a pressure sensor (preferably a strain gauge pressure sensor) for monitoring and sensing pressure, is arranged on the inner end surface of the fixing base 300, and is capable of detecting pressure value data generated by the charging gun 400 after being inserted into the fixing base 300 and sending the pressure value data to the control module 102.
The control module 102 is connected to the monitoring module 101, and may be a single chip for receiving the pressure value data from the monitoring module 101 and controlling the indication module 103 to operate according to the result of the logic judgment. The control module 102 is preset with a threshold value therein, and divides the pressure value range into at least two value ranges according to the threshold value. The pressure value range can be from 0 to infinite pressure value range, and the critical value is one (or more) boundary points in the pressure value range, so that the critical value can divide the pressure value range into a plurality of value intervals, and if the critical value is A, the pressure value range can be divided into a plurality of value intervals
And
two value intervals; the critical value is A, B (A)<B) Then can be divided into
、
And
three numerical intervals. During operation, the control module 102 compares the received pressure value data with a threshold value, classifies the pressure value data into a numerical value interval according to the comparison result, and generates an execution instruction to the corresponding instruction module 103.
The indication module 103 may adopt a light emitting diode capable of emitting light according to an execution instruction of the control module 102, and therefore the number of the indication module 103 may be the same as the number of the divided value intervals, and the indication module may correspond to the divided value intervals one by one. Preferably, the light emitting color of each indication module 103 is different. Each light emitting head of the indication module 103 needs to protrude out of the housing 200 for the human eye to observe.
Preferably, the threshold values in the present invention are two, i.e., a first threshold value a and a second threshold value B, and the first threshold value a is smaller than the second threshold value B. The control module 102 divides the pressure value range into a first value interval lower than a first critical value A range
A second value interval between the first critical value A and the second critical value B
And a third value interval higher than the second critical value B
. The invention sets the following steps: when the pressure value data belongs to the first numerical value interval, the situation that the charging gun 400 is easy to loosen and fall off due to insufficient depth of the charging gun 400 inserted into the fixed seat 300 is shown; when the pressure value data belongs to the second numerical value interval, it indicates that the depth of the charging gun 400 inserted into the fixing seat 300 is moderate, but the charging gun is not completely inserted, and looseness may occur(ii) a condition; when the pressure value data belongs to the third numerical value interval, the depth of the charging gun 400 inserted into the fixing seat 300 is enough and complete, and the charging gun will not loosen or fall off basically.
Correspondingly, the indication module 103 includes a first indicator light 103a, a second indicator light 103b and a third indicator light 103c, which are all light emitting diodes. The invention sets the following steps: the first indicator light 103a can emit red light, the second indicator light 103b can emit yellow light, and the third indicator light 103c can emit green light.
When the pressure value data measured by the monitoring module 101 belongs to the first value interval, the control module 102 generates an execution instruction to the first indicator light 103a to make it emit red light.
When the pressure value data measured by the monitoring module 101 belongs to the second value interval, the control module 102 sends an execution instruction to the second indicator light 103b to emit yellow light.
When the pressure value data measured by the monitoring module 101 belongs to the third value interval, the control module 102 generates an execution instruction to the third indicator light 103c, so that the third indicator light emits green light.
In summary, after the user uses up the charging gun 400 and inserts the fixing base 300, whether the self-inserting depth is sufficient or not can be judged through the different light of the indication module 103, and whether the risk of loosening or insufficiency exists or not can be judged.
Further, the monitoring circuit 100 further includes a voice module 104, and the voice module 104 is used for broadcasting voice. The voice module 104 is composed of a loudspeaker, an audio power amplifier chip, a 32 Mbit serial flash memory and an MP3 chip. The memory is used for storing voice information to be played; the audio power amplifier chip is used for amplifying the weak electric signal from the signal source so as to drive the loudspeaker to make sound; the MP3 chip is a chip providing a serial port, integrates hard decoding of MP3 and WAV, and can play designated music and play music through simple serial port instructions. The voice module 104 described above is prior art and will not be redundantly described here.
When the pressure value data measured by the monitoring module 101 belongs to the first numerical value interval or the second numerical value interval, the control module 102 sends a voice broadcast instruction to the voice module 104. Specifically, the present invention sets: when the pressure value data measured by the monitoring module 101 belongs to a first numerical value interval, the control module 102 controls the voice module 104 to broadcast that the gun head is not completely inserted and please continue to be inserted; when the pressure value data measured by the monitoring module 101 belongs to the second numerical value interval, the control module 102 controls the voice module 104 to report that the insertion depth is insufficient and the insertion is continued. When the pressure value data that monitoring module 101 surveyed belong to the third numerical value interval, because the condition is qualified, consequently do not report the pronunciation, or report "grafting is qualified, thanks. Of course, to avoid the false alarm voice, the control module 102 may be programmed to control the voice module 104 to perform the voice prompt after the pressure value data received by the control module is increased to a fixed value and maintained for a period of time (e.g. 3 seconds).
Further, the monitoring circuit 100 further includes a transceiver module 105, which is connected to the control module 102. The transceiver module 105 is a GPRS module with an external antenna for wireless communication with the server 500. The control module 102 sends the received pressure value data and the comparison result between the pressure value data and the critical value to the server 500 through the transceiver module 105 for storage, so as to form a database, and the database can be accessed through the monitoring terminal 600. The monitoring terminal 600 here is a monitoring computer set up by the equipment maintenance side, and can refer to the on-site real-time comparison result and the plugging condition, and also can refer to the historical data. The preferred can look over and analyze each historical grafting data information picture of filling the electric pile simulator according to the database, and the incomplete condition of pegging graft appears for a long time or often when a certain electric pile simulator is filled, can tentatively judge from this: the fixing base 300 of the charging pile simulator may have quality defects or have blockage and obstacles inside so as to arrange technicians to perform field inspection or replacement.
Of course, it is obvious that the monitoring circuit 100 further comprises a power supply module, which is a power supply of the monitoring circuit 100 and is connected with the monitoring module 101, the control module 102, the indication module 103, the voice module 104 and the transceiver module 105 at the same time to provide the power supply required for the operation thereof.
It should be noted that: since the fixing base 300 is fixed on the outer sidewall 200, the outer sidewall 200 has a mounting hole 201 for fitting the fixing base 300.
In the present invention, the main body of the charging gun 400 is a dc charging gun in the prior art, but the main body is different from the dc charging gun in that: the charging gun 400 of the present invention has a longitudinal slip 401 (a bar-shaped convex structure); the fixing base 300 main body is a direct current charging gun fixing base in the prior art, but the difference lies in that: the fixing base 300 of the invention is provided with a slot 301 matched with the inserting strip 401, the fixing base 300 is fixed in the mounting hole 201, and the edge of the mounting hole 201 is provided with a socket 201a opposite to the slot 301.
The modules of the monitoring circuit 100 are integrated on a circuit board B, which is fixed on the rear end surface of the holder 300 (preferably, the outer edge profile of the circuit board B is matched with the rear end surface of the holder 300). The monitoring module 101 is connected to the control module 102 through a wire, and the monitoring module 101 is fixed to the bottom surface of the slot 301.
Preferably, a pressure plate 101a is fixed to a pressure end (i.e., a pressure acting point of the pressure sensor) of the monitoring module 101, and a longitudinal spring 101b is fixed to the other side of the pressure plate 101a, and the spring 101b is embedded in the slot 301 and can longitudinally extend and contract. After the charging gun 400 is inserted into the fixing seat 300, the insert 401 can penetrate through the socket 201a, be inserted into the slot 301, and press the spring 101b, transmit pressure to the pressing plate 101a through the spring 101b, and finally press the monitoring module 101 by the pressing plate 101a, so as to generate monitoring data.
Furthermore, the charging pile simulator provided by the invention can prevent the charging gun from being damaged by the external environment and is convenient for the insertion and fixing operations of the charging gun. The specific scheme is as follows:
the housing 200 is provided with a protection assembly 700, and the protection assembly 700 is located above the fixing base 300 and has a protection function on the fixing base 300 and the charging gun 400 inserted therein.
The shield assembly 700 includes a first shield 701, a second shield 702, and a third shield 703. Wherein, the second protection cover 702, the third protection cover 703 and the first protection cover 701 are nested in sequence: the second hood 702 can be inserted into the third hood 703 or turned out of the third hood 703, and the third hood 703 can be inserted into the first hood 701 or turned out of the first hood 701 with the second hood 702, and the first hood 701 is fixed to the housing 200 so as not to be rotatable. Thus, the shield assembly 700 includes at least two states: one state is a housed state in which the second shield 702 and the third shield 703 are all housed in the second shield 702; the other state is a fully deployed state in which the third hood 703 is rotated out of the first hood 701 and the second hood 702 is rotated out of the third hood 703. When the shield assembly 700 is in the fully deployed state, the second shield 702, which is turned over, can cover the holder 300 and the upper portion of the charging gun 400.
Specifically, the second shield 702, the third shield 703 and the first shield 701 are identical in structural form (except for partial size), and are nested layer by layer, the first shield 701 is located at the outermost layer, the second shield 702 is located at the innermost layer, and the third shield 703 is located between the first shield 701 and the second shield 702.
The first cover 701 includes a pair of first side plates 701a parallel to each other and a first connecting plate 701b connecting top edges of the two first side plates 701 a. Preferably, the first side plate 701a is a fan-shaped side plate, and the first connecting plate 701b is a curved plate connecting the arc-shaped edges of the two first side plates 701 a.
The third mask 703 is fitted to the inner contour of the first mask 701 and includes a corresponding pair of third side panels 703a and a third web 703b connecting the top edges of the third side panels 703 a. Like the first cover 701, the third side plate 703a is also fan-shaped, and has the same central angle as the first side plate 701a, but a smaller radius than the first side plate 701 a. The third connecting plate 703b is a curved plate connecting the arc-shaped edges of the two third side plates 703 a.
The second shield 702 fits the interior contour of the third shield 703 and includes a corresponding pair of second side panels 702a and a second connecting panel 702b that connects the top edges of the two second side panels 702 a. Similarly, the second side plate 702a is also fan-shaped, and has the same central angle as the third side plate 703a, but a smaller radius than the third side plate 703 a. The second connecting plate 702b is a curved plate connecting the arc-shaped edges of the two second side plates 702 a.
It should be noted that: the lower extreme of second protection casing 702, third protection casing 703 and first protection casing 701 three articulates jointly to make second protection casing 702 and third protection casing 703 all have the ability that can carry out relative rotation, and the fan-shaped circular of three curb plates is all passed through to the articulated transverse axis of three.
Further, the inner side wall of the first side plate 701a is provided with a first arc-shaped groove 701a-1 corresponding to the turning travel track of the third prevention cover 703, the outer side wall of the third side plate 703a is provided with a corresponding first protrusion 703a-1, and the first protrusion 703a-1 is embedded in the first arc-shaped groove 701a-1 and can slide relatively. Preferably, when the first protrusion 703a-1 slides to the inner end of the first arc-shaped groove 701a-1, the first protection cover 701 completely covers the third protection cover 703 in the transverse projection; when the first protrusion 703a-1 slides to the outer end of the first arcuate groove 701a-1, the third shield 703 protrudes largely out of the first shield 701, but there is any angular overlap (which is beneficial for waterproofing).
The inner side wall of the third side plate 703a is provided with a second arc-shaped groove 703a-2 corresponding to the turning travel track of the second shield 702, the outer side wall of the second side plate 702a is provided with a corresponding second protrusion 702a-1, and the second protrusion 702a-1 is embedded in the second arc-shaped groove 703a-2 and can slide relatively. When the second projection 702a-1 slides to the inner end of the second arc-shaped groove 703a-2, the third shield 703 completely covers the second shield 702 in lateral projection; when the second projection 702a-1 slides to the outer end of the second arcuate groove 703a-2, the second shield 702 protrudes largely beyond the third shield 703, but there is any angular overlap (which is beneficial for waterproofing).
It can be seen that when the shield assembly 700 is in the fully deployed state, there is a partial overlap between the third shield 703 and the first shield 701, and between the second shield 702 and the third shield 703. Preferably, when the shield assembly 700 is in the fully deployed state, the exposed side of the second shield 702 is in the horizontal state, and the central angles of the second shield 702, the third shield 703 and the first shield 701 are the same (n), and the central angles of the two overlapping portions are the same (α), so that:
the invention is to get
，
Therefore, the third prevention cover 703 rotates in total from the accommodated state to the fully expanded state
(ii) a The second shield 702 rotates in total
。
In the invention, the third protection cover 703 is in clearance fit with the first protection cover 701, a clearance is reserved between the third protection cover 703 and the first protection cover 701, and when the third protection cover 703 and the first protection cover 701 rotate relatively, the first protection cover 701 has no friction action or has a minimum friction action on the third protection cover 703; similarly, the second shield 702 is also a clearance fit with the third shield 703, with little or no relative friction.
Further, the inner edge of the second connecting plate 702b is fixed with a connecting member 702b-1, and the housing 200 is fixed with a fitting 203 corresponding to the connecting member 702 b-1. The connecting member 702b-1 may be an iron block, the mating member 203 may be a magnet, and the second shield 702 may be connected to the mating member 203 through the connecting member 702b-1 so as to be accommodated in the first shield 701 together with the third shield 703.
From the above, it can be seen that: when the shield assembly 700 is in the stowed state, only the innermost second shield 702 need be pushed outwardly. After the connection member 702b-1 is disengaged from the mating member 203, the second shield 702 will self-lock due to gravityTurning over downwards when turning over
Thereafter, the second hood 702 can pull the third hood 703 to turn over along the way until the third hood 703 turns over
Thereafter, the shield assembly 700 is in a fully deployed state.
Similarly, when the shield assembly 700 is in the fully deployed state, the innermost second shield 702 is pushed in a reverse direction inwardly, when inverted
Thereafter, the second hood 702 can pull the third hood 703 to reverse the direction until the third hood 703 is turned
Thereafter, the shield assembly 700 is in the stowed state, and the temporary locking is eventually achieved by the engagement between the connection 702b-1 and the mating member 203.
As shown in fig. 7 to 9, in the above process, the protection component 700 is automatically changed from the storage state to the fully-deployed state by the driving component 800, and the specific scheme is as follows:
the charging pile simulator further comprises a driving assembly 800. The driving assembly 800 comprises a rotating block 801 and a pushing cross bar 802, wherein the rotating block 801 is a strip-shaped structure, is hinged on the housing 200 and can rotate around a hinge point 801a thereof, and the housing 200 is provided with an allowance port 202 corresponding to the rotating stroke of the rotating block 801; the push bar 802 is a transverse, round bar structure.
The rotating block 801 is divided into a first side 801b and a second side 801c by a hinge point 801a, the end of the first side 801b extends into the housing 200, the push cross bar 802 is transversely fixed at the end of the second side 801c, and the push cross bar 802 is perpendicular to the second side 801 c.
If the rotation block 801 is rotated, the cross bar 802 is pushed to squeeze the second shield 702, so as to squeeze and turn the second shield 703 from the third shield 703. Preferably, the second side plate 702a has a fixing block 702a-2 on the inner side wall thereof (the fixing block 702a-2 is a block structure), and the pushing rail 802 can contact and press the fixing block 702a-2, so that the second shield 702 is pressed and turned over from the third shield 703. In addition, the driving assembly 800 further includes a stretching member 803 (the stretching member 803 is a stretching spring), one end of the stretching member 803 is fixed to the second side 801c or the pushing cross bar 802, and the other end is fixed to the housing 200, and generates a pulling force on the second side 801c, so as to have an effect of resetting the rotating block 801.
In the present invention, the main body of the charging gun 400 is a dc charging gun in the prior art, but the main body is different from the dc charging gun in that: the charging gun 400 of the present invention has a longitudinal slip 401 (a bar-shaped convex structure); the fixing base 300 main body is a direct current charging gun fixing base in the prior art, but the difference lies in that: the fixing base 300 of the invention is provided with a slot 301 matched with the inserting strip 401, the fixing base 300 is fixed in the mounting hole 201, and the edge of the mounting hole 201 is provided with a socket 201a opposite to the slot 301.
The invention sets the following steps: when the charging gun 400 is not inserted into the fixing base 300 and the protection assembly 700 is in the storage state, the end of the first side 801b extends to the track of the slot 301. When the charging gun 400 is inserted into the fixing base 300, the insert 401 can pass through the insertion opening 201a, be inserted into the insertion groove 301, and press the end of the first edge 801b, so that the rotating block 801 rotates, and finally the second protection cover 702 is pressed and turned over from the third protection cover 703.
In summary, after the charging gun 400 is used, the protection assembly 700 can be automatically and completely unfolded and put down only by directly inserting the charging gun back into the fixing base 300, so as to realize protection.
In another embodiment, the invention may not include the third shield 703 and the shield assembly 700 includes only the first shield 701 and the second shield 702. Similarly, one side of the first protection cover 701 is fixed on the housing 200 of the charging pile simulator, and the second protection cover 702 is located inside the first protection cover 701 and can be hinged at the lower ends thereof to be turned out of the first protection cover 701 or embedded into the first protection cover 701 again. Meanwhile, the first cover 701 includes a pair of first side plates 701a parallel to each other and a first connecting plate 701b connecting top edges of the two first side plates 701 a; the second shield 702 is fitted to the inner contour of the first shield 701, and includes a corresponding pair of second side plates 702a and a second connection plate 702b connecting top edges of the two second side plates 702 a. Since the specific implementation process is the same as the case of retaining the third mask 703, it is not described herein.
