After the device control system receives a vehicle taking operation request of a user, the device control system needs to firstly provide inquiry whether the vehicle scheduling is allowed for a parking space where the vehicle of the user is located to the charging control unit, and can only operate the vehicle scheduling after obtaining confirmation of the vehicle scheduling.

When a user puts any vehicle driven into the parking equipment by the electric vehicle into or out of a parking space for parking, the external slow charging accessory configured on the vehicle is taken out and connected with the vehicle end socket, and the user request charging button is pressed to indicate that the user selects to allow the parking equipment to charge the electric vehicle when the electric vehicle is parked and then leaves. Since the user cannot enter the parking space, the charging plug of the external slow charging accessory disposed on the vehicle must be inserted and removed by the worker.

The charging control unit receives the operation information of the user charging request button, obtains the position of the corresponding parking space where the user vehicle is finally parked from the equipment control system, firstly searches the five data storage areas, deletes all records possibly existing corresponding to the parking space (the operation can avoid the situation that the same parking space has past records in any data storage area to influence the current operation), then records the number of the parking space at the tail end of the parking space number storage area which is requested to be charged, the user vehicles of the parking space sequentially enter a queuing sequence which is requested to be charged, and the parking space is displayed to be in a charging request state at the corresponding position of the information display screen.

The charging control unit is provided with automatic inspection time.

When the charging control unit is in the automatic polling time, the state information sent by the state detection element of the charging socket unit corresponding to the parking space in the parking space number storage area requesting charging is sequentially read, and then the following judgment and processing are made one by one:

firstly, if the state information indicates that no plug is available, the parking space is displayed in a state of no plug at a corresponding position of an information display screen.

When the charging control unit is in the automatic inspection time, the charging current values of the current detection elements of all the charging socket units are read and accumulated to obtain the current total charging current, and then the following judgment and processing are carried out one by one:

firstly, if the total charging current is less than the preset rated total current lower limit and a parking space number storage area waiting for charging has a parking space waiting for charging, a signal is sent to enable a charging on-off switch of a charging socket unit corresponding to the parking space which is in front of a waiting charging queuing sequence and in a plug insertion state to be in a conducting state, the number of the parking space is recorded at the tail end of the parking space number storage area which is being charged, and the parking space is displayed to be in a charging state at a corresponding position of an information display screen; and simultaneously, deleting the record corresponding to the parking space number from the parking space number storage area waiting for charging. The charging sequence is arranged according to the entering sequence. Of course, other charging sequencing rules may be adopted.

Secondly, if the total charging current is larger than the preset rated total current upper limit, a signal is sent to enable a charging on-off switch of a charging socket unit corresponding to a parking space recorded at the tail end of the parking space number storage area which is being charged to be in an off state, the parking space is displayed to be in a 'waiting for charging' state at a corresponding position of an information display screen, and then the tail end record is deleted from the parking space number storage area which is being charged; meanwhile, a blank record is added to the foremost part of the parking space number storage area waiting for charging, and the content of the parking space number is stored in the blank record. The above operation is also in line with the principle of arranging charging sequence. Of course, other charging sequencing rules may be adopted.

The staff needs to carry out routing inspection regularly or irregularly; before polling, recording parking space information in a state of waiting for charging and having no plug, parking space information in a state of requesting for charging and having no plug, parking space information in a state of charging completion and having a plug inserted, parking space information in a state of charging failure and having a plug inserted, operating a polling switch to be in a working state, and entering a parking space of parking equipment to complete the following work:

firstly, entering a parking space in a 'waiting for charging' state and a 'plug-free' state, and inserting a charging plug of a corresponding user electric vehicle into a charging socket unit of the corresponding parking space.

Secondly, entering a parking space in a ' charging request ' state without a plug ', and inserting a charging plug of a corresponding user electric vehicle into a charging socket unit of the corresponding parking space.

And thirdly, entering a parking space in a charging state and a plug-free state, and inserting a charging plug of the corresponding user electric automobile into a charging socket unit of the corresponding parking space.

And fourthly, entering a parking space in a charging completion state and a plug insertion state, pulling out a charging plug of the corresponding user electric automobile, prompting the user to complete charging at a proper position of the electric automobile, and asking for receiving a slow charging accessory when the user gets the electric automobile.

And fifthly, entering a parking space in a charging fault state and a plug-in state, pulling out a charging plug of the corresponding user electric automobile, prompting the user of the charging fault at a proper position of the electric automobile, and asking for receiving a slow charging accessory when the user gets the automobile.

When the charging control unit is in the automatic inspection time, the following detection and treatment are also carried out:

firstly, sequentially reading detection signals of state detection elements of corresponding charging socket units in a charging-completed parking space number storage area; when the detection signal indicates that no plug is available, namely the parking space is displayed in a state of no plug at the corresponding position of the information display screen, and the parking space number corresponding to the parking space number storage area in which the charging is completed is deleted.

Secondly, sequentially reading detection signals of state detection elements of corresponding charging socket units in the parking space number storage area with charging faults; and when the detection signal indicates that no plug is available, displaying that the parking space is in a 'plug-free' state at the corresponding position of the information display screen, and deleting the parking space number corresponding to the parking space number storage area with the charging fault.

When the user carries out the vehicle taking operation, the equipment control system provides the charging control unit with an inquiry whether the parking space where the user vehicle is located allows vehicle scheduling.

The charging control unit receives the inquiry, namely, carries out the following information inquiry:

reading a signal of a state detection element of the charging socket unit corresponding to the parking space, and confirming whether the charging socket unit is in a state without plug insertion; and respectively searching the parking space number storage area which is charged, the parking space number storage area which is being charged, the parking space number storage area waiting for charging and the parking space number storage area with charging failure.

If the charging socket unit is in a plug-in state or a record of a parking space related to a vehicle taking operation of a corresponding user exists in any one of a parking space number storage area which is charged, a parking space number storage area which is being charged, a parking space number storage area which is waiting for charging and a parking space number storage area which is charged with a fault, the charging control unit sends a signal for forbidding vehicle dispatching to the equipment control system, prompts a worker to go to the parking space, extracts the charging plug, and prompts the user to take the vehicle and to receive a slow charging accessory at a proper position of the electric vehicle; then, the charging control unit repeatedly reads the signal of the state detection element of the charging socket unit corresponding to the parking space until the charging socket unit is confirmed to be in a state without plug insertion, namely, records of parking spaces related to the vehicle taking operation of a corresponding user originally existing in any one of the parking space number storage areas of the parking space number storage area with charging completed, the parking space number storage area with charging in progress, the parking space number storage area with waiting for charging and the parking space number storage area with charging failure are deleted, and confirmation allowing vehicle scheduling is sent to the equipment control system. Parking spaces with plug-ins do not of course allow vehicle scheduling. However, although the detection result is that there is no plug, if there is a record of the parking space in any parking space number storage area that has completed charging, is charging, waits for charging, or has a charging failure, there is a high possibility that the corresponding status detection element fails or the charging plug is inserted insecurely. Therefore, the above state must be handled by a worker who goes to the parking space.

If the charging socket unit is in a state without plug insertion and no record corresponding to the parking space related to the vehicle taking operation of the user exists in any one of the parking space number storage area which is charged, the parking space number storage area which is being charged, the parking space number storage area which is waiting for charging and the parking space number storage area with charging failure, the charging control unit sends confirmation allowing vehicle scheduling to the equipment control system.

Secondly, if the charging current value is larger than the set upper limit of the single current, a signal is sent to enable a charging on-off switch of a corresponding charging plug unit to be in an off state, the number of the parking space is recorded at the tail end of a parking space number storage area with charging failure, and the parking space is displayed to be in a charging failure state at the corresponding position of an information display screen; and simultaneously, deleting the record corresponding to the parking space number in the storage area of the parking space number which is being charged.

When the charging control unit is in the automatic inspection time, the charging current values of all the charging plug units are read through the CAN bus and accumulated to obtain the current total charging current, and then the following judgment and processing are carried out:

firstly, if the total charging current is less than the preset rated total current lower limit and a parking space number storage area waiting for charging has a parking space waiting for charging, a signal is sent to enable a charging on-off switch of a charging plug unit corresponding to a parking space which is in front of a waiting charging queue sequence and in a socket insertion state to be in a conducting state, the number of the parking space is recorded at the tail end of the parking space number storage area which is charging, and the parking space is displayed to be in a charging state at a corresponding position of an information display screen; and simultaneously, deleting the record corresponding to the parking space number from the parking space number storage area waiting for charging. The charging sequence is arranged according to the entering sequence. Of course, other charging sequencing rules may be adopted.

Secondly, if the total charging current is larger than the preset rated total current upper limit, a signal is sent to enable a charging on-off switch of a charging plug unit corresponding to a parking space recorded at the tail end of the parking space number storage area which is being charged to be in an off state, the parking space is displayed to be in a 'waiting for charging' state at the corresponding position of an information display screen, and then the tail end record is deleted from the parking space number storage area which is being charged; meanwhile, a blank record is added to the foremost part of the parking space number storage area waiting for charging, and the content of the parking space number is stored in the blank record. The above operation is also in line with the principle of arranging charging sequence. Of course, other charging sequencing rules may be adopted.

The staff needs to carry out routing inspection regularly or irregularly; before patrolling and examining, firstly recording parking stall information which is in a state of waiting for charging and separating from a socket, parking stall information which is in a state of requesting charging and separating from the socket, parking stall information which is in a state of charging and inserting into the socket, parking stall information which is in a state of charging completion and inserting into the socket, parking stall information which is in a state of charging failure and inserting into the socket, operating an patrolling and examining switch to be in a working state, and then entering a parking equipment parking stall to complete the following work:

firstly, entering a parking space in a state of waiting for charging and being separated from a socket, and inserting a slow charging standard plug of a charging plug unit into a slow charging socket of a user electric automobile.

Secondly, entering a parking space in a 'charging request' state and an 'outlet socket' state, and inserting a slow charging standard plug of the charging plug unit into a slow charging socket of the user electric automobile.

And thirdly, entering a parking space in a charging state and an outlet state, and inserting a slow charging standard plug of the charging plug unit into a slow charging socket of the user electric automobile.

And fourthly, entering a parking space in a charging completion state and a socket insertion state, pulling out the slow charging standard plug of the charging plug unit, prompting a user to complete charging at a proper position of the electric automobile, and covering a slow charging socket when the user takes the electric automobile.

And fifthly, entering a parking space in a charging fault state and a socket insertion state, pulling out the slow charging standard plug of the charging plug unit, prompting a user of the occurrence of the charging fault at a proper position of the electric automobile, and requesting to cover a slow charging socket when the user gets out of the automobile.

firstly, sequentially reading the state information of a slow charging standard plug in a corresponding charging plug unit in a charging-completed parking space number storage area through a CAN bus; and when the state information is the socket, namely the parking space is displayed in a socket-out state at the corresponding position of the information display screen, and the parking space number corresponding to the parking space number storage area in which the charging is completed is deleted.

Secondly, sequentially reading the state information of the slow charging standard plug in the corresponding charging plug unit in the parking space number storage area with the charging fault through the CAN bus; and when the state information is the socket, namely the parking space is displayed in a socket-out state at the corresponding position of the information display screen, and the parking space number corresponding to the parking space number storage area with the charging fault is deleted.

reading the state information of a slow charging standard plug in a charging plug unit corresponding to the parking space through a CAN bus, and determining whether the slow charging standard plug is in a socket-out state; and respectively searching the parking space number storage area which is charged, the parking space number storage area which is being charged, the parking space number storage area waiting for charging and the parking space number storage area with charging failure.

If the slow charging standard plug is in a socket inserting state or a record of a parking space related to a vehicle taking operation of a corresponding user exists in any one of a parking space number storage area which is charged, a parking space number storage area which is being charged, a parking space number storage area which is waiting for charging and a parking space number storage area which is charged with a fault, the charging control unit sends a signal for forbidding vehicle dispatching to the equipment control system and prompts a worker to go to the parking space to pull out the slow charging standard plug and prompt the user to cover a slow charging socket when the user takes the vehicle at a proper position of the electric vehicle; then, the charging control unit repeatedly reads the state information of the slow charging standard plug in the charging plug unit corresponding to the parking space until the slow charging standard plug is confirmed to be in a state without being inserted into the socket, namely, the original existing record of the parking space related to the vehicle taking operation of the corresponding user in any one of the parking space number storage area with charging completed, the parking space number storage area with charging in progress, the parking space number storage area with waiting for charging in progress and the parking space number storage area with charging failure is deleted, and the confirmation allowing vehicle scheduling is sent to the equipment control system.

Parking spaces with plug-ins do not of course allow vehicle scheduling. However, although the detection result is that there is no plug, if there is a record of the parking space in any parking space number storage area that has completed charging, is charging, waits for charging, or has a charging failure, there is a high possibility that the corresponding status detection element fails or the charging plug is inserted insecurely. Therefore, the above state must be handled by a worker who goes to the parking space.

If the slow charging standard plug is not inserted into the socket and no record corresponding to the parking space involved in the vehicle taking operation of the user exists in any one of the parking space number storage area which is charged, the parking space number storage area which is being charged, the parking space number storage area which waits to be charged and the parking space number storage area with charging failure, the charging control unit sends confirmation allowing vehicle scheduling to the equipment control system.
