Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the related art, the server pushes the recorded parking status information to each client device, and it may be possible that each client device cannot receive the parking status information due to the influence of network transmission, so that the following problems may occur: the updated data on which the client device and the server device update the parking status information are inconsistent, which will certainly affect the effect of data synchronization.

In order to solve the above technical problems, embodiments of the present invention provide a data updating method applied to a client device side and a data updating method applied to a server side.

The data updating method applied to the client device side provided by the embodiment of the invention comprises the following steps:

The data updating method applied to the server side provided by the embodiment of the invention comprises the following steps:

The data updating method applied to the client device side provided in the embodiment of the present invention may be applied to any device equipped with a client for updating the parking status information, such as a handheld POS, a mobile phone, a tablet computer, and the like.

Accordingly, the data updating method applied to the server side provided by the embodiment of the present invention may be applied to any server that needs to update the information of the berthage-like body and serves a client installed in the client device that needs to update the berthage state information.

Moreover, a server can serve a plurality of client devices, namely, the server can communicate with the plurality of client devices, so that the update of the berth state information in the server and the plurality of client devices is realized.

In addition, the server and the client device may store the parking space state information in various forms, and the embodiment of the present invention is not limited in particular. The parking space state information may be stored, for example, in the form of a table, each entry in the table including the parking number of a parking space and other data related to the number plate, the parking start time, and the like of the parking space.

First, a data updating method applied to a client device according to an embodiment of the present invention is described in detail below.

Fig. 1 is a schematic flowchart of a data updating method applied to a client device according to an embodiment of the present invention. As shown in fig. 1, the method may include the steps of:

s101: updating second berthing state information currently stored by the client equipment based on first berthing state information currently stored by the server;

s102: if the second berth state information is successfully updated, modifying the updated second berth state information;

s103: sending the berthing state modification information to the server so that the server updates the first berthing state information according to the berthing state modification information;

Specifically, the method comprises the following steps:

in the embodiment of the present invention, the client device stores the second berthing status information at the current moment. Furthermore, when the actual situation of at least one parking space in each parking space changes, the client device needs to modify the parking space state information of the at least one parking space in the currently stored second parking space state information, so as to modify the currently stored second parking space state information.

For example, when a vehicle is parked at an idle parking space, the client device needs to record the license plate number, the parking start time, and the like of the parked vehicle in the currently stored second parking space state information and the state information corresponding to the parking space number of the parking space; correspondingly, when a vehicle drives away from a certain parking space, the client device needs to delete the license plate number of the driven-away vehicle from the state information corresponding to the parking space number in the second parking space state information stored currently, and record the parking stop time and the like.

In order to ensure that when the client device updates the currently stored second parking status information, the second parking status information is consistent with the currently stored first parking status information of the server, therefore, when the client device needs to modify the currently stored second parking status information, the client device may first perform the above step S101, and update the currently stored second parking status information of the client device based on the currently stored first parking status information of the server.

In this way, the updated second parking status information in the client device can be made to be consistent with the first parking status information currently stored by the server, that is, the parking status information that the client device needs to modify is consistent with the first parking status information currently stored by the server.

Optionally, in a specific implementation manner, as shown in fig. 2, the manner in which the client device executes the step S101 may include the following steps:

s201: sending a parking status update request to a server so that the server determines parking status update information based on the currently stored first parking status information and feeds back the determined parking status update information to the client device;

s202: receiving the berth state updating information, and updating the second currently stored berth state information based on the received berth state updating information.

In this specific implementation, when determining that the second currently stored parking status information needs to be modified, the client device may first send a parking status update request to the server. Therefore, after receiving the parking status update request, the server can determine the parking status update information based on the currently stored first parking status information and feed back the parking status update information to the client device.

In this way, after receiving the parking status update information, the client device may update the currently stored second parking status information based on the parking status update information. And after the updating is successful, the second berth state information currently stored by the client equipment is the same as the first berth state information currently stored by the server.

Optionally, in a specific implementation manner, the server may feed back the currently stored first parking status information as the parking status update information to the client device. In this way, the client device can use the received first parking status information to overwrite the currently stored second parking status information, thereby completing the update of the second parking status information, and obviously, the updated second parking status information is the first parking status information currently stored by the server.

Optionally, in another specific implementation manner, the parking status update request sent by the client device to the server may carry a version number of the second parking status information currently stored by the client device.

Thus, in this specific implementation manner, the server may determine the content of the second parking status information currently stored by the client device based on the received version number of the second parking status information currently stored by the client device, so that the server may determine the difference information between the first parking status information currently stored by the server and the second parking status information currently stored by the client device, and feed back the difference information as the parking status update information to the client device. Furthermore, when the client device receives the difference information, the client device may change the relevant information in the currently stored second parking status information based on the difference information, thereby completing the update of the second parking status information, and obviously, the updated second parking status information is consistent with the first parking status information currently stored by the server.

In this specific implementation manner, optionally, the difference information determined by the server may include a parking number that needs to be modified in the second parking status information currently stored by the client device and specific data content of the parking status information of the parking number, and the difference information indicates a manner of changing the specific data content.

In this way, the client device can change the specific data content of the parking status information of the parking number included in the difference information in the second currently stored parking status information in the changing manner indicated by the difference information.

For example, the difference information includes a parking number 3, and the specific data content of the parking status information of the parking number: the license plate number C and the parking start time T3, and the specific data content indicated by the difference information is modified in such a manner as to be added, the client device can add the license plate number C and the parking start time T3 to the parking status information of the parking number 3 among the currently stored second parking status information.

For another example, the difference information includes a parking number 4, and specific data content of the parking status information of the parking number: the license plate number D and the parking stop time T4, and the specific data content indicated by the difference information is modified by deleting the license plate number and recording the stop time, the client device may delete the license plate number D from the parking status information of the parking space 4 among the currently stored second parking status information, and record the parking stop time T4.

Further, when the client device updates the second parking status information currently stored in the client device based on the difference information, and the update is successful, the version number of the second parking status information currently stored in the client device is changed accordingly. After the update is successful, the second parking status information currently stored by the client device is the same as the first parking status information currently stored by the server, so that after the update is successful, the version number of the second parking status information currently stored by the client device is the same as the version number of the first parking status information currently stored by the server.

After the second parking status information currently stored in the client device is successfully updated, what is currently stored in the client device is: the updated second berth-state information. At this time, the client device may continue to perform step S102 to modify the updated second berth-state information.

That is to say, the client device may modify the updated second parking space state information according to a change in an actual situation of at least one parking space in each parking space, so as to obtain modified second parking space state information, where the second parking space state information currently stored by the client device is the modified second parking space state information.

Since the updated second parking status information is consistent with the first parking status information currently stored by the server, and the modified second parking status information is inconsistent with the updated second parking status information, the modified second parking status information is inconsistent with the first parking status information currently stored by the server, so that the client device may continue to execute the step S103 to send the parking status modification information to the server, where the parking status modification information is determined based on the modified second parking status information. Therefore, after receiving the parking status modification information, the server can update the first parking status information stored in the server according to the parking status modification information.

At this time, when the server succeeds in updating the first currently stored parking status information according to the parking status modification information, the modified second parking status information stored by the client device and the updated first parking status information currently stored by the server may be the same again, so that the data consistency of the server and the client device is ensured, and the effect of data synchronization between the server and the client device is ensured.

Optionally, in a specific implementation manner, the client device may feed back, as the modified parking status information, the currently stored modified second parking status information to the server. In this way, the server can use the received modified second parking status information to overwrite the currently stored first parking status information, thereby completing the update of the currently stored first parking status information.

Obviously, when the server successfully updates the first currently stored parking status information according to the parking status modification information, the updated first parking status information is the modified second parking status information currently stored by the client device.

Optionally, in another specific implementation manner, the client device may determine difference information before and after the second parking status information is modified, and send the determined difference information as the parking status modification information to the server. In this way, when the server receives the difference information, the server can change the related information in the currently stored first parking status based on the difference information, thereby completing the update of the first parking status information.

In this specific implementation manner, the difference information determined by the client device may include a parking number that needs to be modified in the first parking status information currently stored by the server and specific data content of the parking status information of the parking number, and the difference information indicates a modification manner of the specific data content.

In this way, the server can change the specific data content of the parking status information of the parking number included in the difference information in the currently stored first parking status information in the changing manner indicated by the difference information.

For example, the difference information includes a parking number 1, and specific data content of the parking status information of the parking number: the license plate a and the parking start time T1, and the specific data content indicated by the data update information is changed in such a manner as to be added, the server can add the license plate a and the parking start time T1 to the parking status information of the parking number 1 among the currently stored first parking status information.

For another example, the difference information includes a parking number 2, and specific data content of the parking status information of the parking number: the license plate number B and the parking stop time T2, and the specific data content indicated by the data update information is changed by deleting the license plate number and recording the stop time, the server may delete the license plate number B from the parking status information of the parking number 2 among the currently stored first parking status information, and record the parking stop time T2.

Optionally, in a specific implementation manner, in step S201, the parking status update request sent by the client device to the server may carry a version number of the second parking status information currently stored by the client device, and the server may store the version number of the first parking status information currently stored by the server.

In this way, when the server receives the version number of the second parking state information currently stored by the client, which is carried in the parking state update request, it may first determine whether the two version numbers are the same.

Furthermore, when the server determines that the two version numbers are different, the server may determine that the second parking status information currently stored by the client device is different from the first parking status information currently stored by the server. Further, the server may determine the parking status update information based on the currently stored first parking status information and feed back the parking status update information to the client device.

Further, in this specific implementation manner, when the client device updates the second parking status information currently stored by the client device based on the difference information, and the update is successful, the version number of the second parking status information currently stored by the client device is changed accordingly. After the update is successful, the second parking status information currently stored by the client device is the same as the first parking status information currently stored by the server, so that after the update is successful, the version number of the second parking status information currently stored by the client device is the same as the version number of the first parking status information currently stored by the server.

Furthermore, when the server determines that the two version numbers are the same, the server may determine that the second parking status information currently stored by the client device is the same as the first parking status information currently stored by the server. At this time, the server may directly send to the client device: and the prompt information is used for prompting that the second berth state information currently stored by the client equipment is the same as the first berth state information currently stored by the server.

At this time, the client device may directly modify the second parking status information currently stored by itself without updating the second parking status information currently stored by itself, and send the parking status modification information to the server, so that the server updates the first parking status information currently stored by itself according to the parking status modification information.

In addition, optionally, in a specific implementation manner, when the client device does not need to modify the second parking status information currently stored by itself, because the first parking status information currently stored by the server may be updated according to the parking status modification information sent by the client device based on other client devices, in order to ensure that the second parking status information currently stored by the client device is consistent with the first parking status information currently stored by the server, the client device may update the second parking status information currently stored by the client device based on the first parking status information currently stored by the server, or when a parking status refresh instruction sent by a user is detected, for example, when a click operation of the user on a refresh button is detected, the client device updates the second parking status information currently stored by the client device based on the first parking status information currently stored by the server.

Furthermore, in step S103, when the server receives the parking status modification information sent by the client device and updates the second parking status information stored in the server based on the parking status modification information, the server may have a failure in updating, that is, the server does not successfully update the first parking status information currently stored in the server according to the parking status modification information.

For example, if the server receives the parking status modification information sent by two different client devices at the same time, the server may determine that a modification conflict occurs, so as not to update the currently stored first parking status information, and return the received two parking status modification information to the respective corresponding client devices. At this time, the server may determine that the first parking status information currently stored by itself is not successfully updated according to the parking status modification information.

For another example, although the client device has updated the second parking status information currently stored by itself based on the first parking status information currently stored by the server before sending the parking status modification information to the server, it is expected that the updated second parking status information currently stored by itself may be made consistent with the first parking status information currently stored by the server. However, since the server may receive the parking status modification information sent by the multiple client devices, and there is a time difference in data transmission between different client devices and the server, when the client device feeds back the parking status modification information to the server, the first parking status information currently stored in the server may have been updated according to the parking status modification information sent by other client devices.

Therefore, the first berth state information currently stored by the server is different from the second berth state information which is not modified in the client equipment and is updated, so that the server can judge that modification conflict occurs, cannot update the updated first berth state information currently stored by the server according to the berth state modification information sent by the client equipment, and returns the received berth state modification information to the client equipment. At this time, the server may determine that the first parking status information currently stored by itself is not successfully updated according to the parking status modification information.

Based on this, optionally, in a specific implementation manner, as shown in fig. 3, the data updating method applied to the client device end provided in the embodiment of the present invention may further include the following steps:

s104: and receiving a modified withdrawal instruction sent by the server, and returning to execute the step S101.

And the modification return instruction is fed back when the server does not successfully update the first berth state information according to the berth state modification information.

Specifically, the method comprises the following steps:

when the server judges that the first berth state information is not successfully updated according to the berth state modification information, a modification return instruction can be generated and sent to the client equipment.

In this way, after receiving the modification return instruction, the client device may determine that the modification conflict occurs at the server, so that, in order to enable the server to successfully update the first currently stored parking status information according to the parking status modification information, the client device may return to perform step S101 again until the server successfully updates the first currently stored parking status information according to the parking status modification information.

Optionally, the modification return instruction may include the parking position state modification information sent by the client device.

Corresponding to the data updating method applied to the client device side provided by the embodiment of the present invention, a detailed description is given below of the data updating method applied to the server side provided by the embodiment of the present invention.

Fig. 4 is a flowchart illustrating a data updating method applied to a server according to an embodiment of the present invention. As shown in fig. 4, the method may include the steps of:

s401: updating second berthing state information currently stored by the client equipment based on the first berthing state information currently stored;

s402: if the second berth state information is updated successfully, receiving berth state modification information sent by the client equipment;

wherein the berth-state-modification information is determined based on the modified second berth-state information;

s403: and updating the first berth state information according to the berth state modification information.

Specifically, the method comprises the following steps:

In order to ensure that when the client device updates the currently stored second parking status information, the second parking status information is consistent with the first parking status information currently stored by the server, therefore, when the client device needs to modify the currently stored second parking status information, the server may first perform step S401 described above, and update the second parking status information currently stored by the client device based on the currently stored first parking status information of the server.

It should be noted that the essence of the server executing step S401 is: the server responds to the request sent by the client device, so that the client device can update the second berth state information currently stored by the client device based on the first berth state information currently stored by the server.

Optionally, in a specific implementation manner, as shown in fig. 5, the manner in which the server executes step S401 may include the following steps:

s501: receiving a berth state updating request sent by client equipment;

s502: and determining parking position state updating information based on the first currently stored parking position state information, and feeding back the determined parking position state updating information to the client device, so that the client device updates the second currently stored parking position state information based on the received parking position state updating information.

After the second parking status information currently stored in the client device is successfully updated, what is currently stored in the client device is: the updated second berth-state information.

The updated second parking status information is consistent with the first parking status information currently stored by the server, and the modified second parking status information is inconsistent with the updated second parking status information, so that the client device can modify the updated second parking status information currently stored by the client device and determine the parking status modification information based on the modified second parking status information, thereby sending the parking status modification information to the server.

Based on this, the server may continue to perform step S402, and receive the parking status modification information sent by the client device.

Furthermore, after receiving the parking status modification information sent by the client device, the server may continue to execute step S403, and update the first currently stored parking status information according to the parking status modification information.

Optionally, in a specific implementation manner, in step S501, the parking status update request sent by the client device to the server may carry a version number of the second parking status information currently stored by the client device, and the server may store the version number of the first parking status information currently stored by the server.

Furthermore, in step S403, when the server updates the second parking status information stored in the server based on the parking status modification information sent by the client device, the server may fail to update the first parking status information currently stored in the server according to the parking status modification information.

Based on this, optionally, in a specific implementation manner, as shown in fig. 6, the data updating method applied to the server side provided in the embodiment of the present invention may further include the following steps:

s404: and if the first berth state information is not successfully updated according to the berth state modification information, sending a modification return instruction to the client equipment so that the client equipment returns the first berth state information currently stored on the basis of the server and updates the second berth state information currently stored by the client equipment.

Specifically, the method comprises the following steps:

Therefore, after receiving the modification return instruction, the client device can determine that the modification conflict occurs at the server, so that in order to enable the server to successfully update the first currently stored parking status information according to the parking status modification information, the client device can return to execute the first parking status information based on the current storage of the server again, and update the second parking status information currently stored by the client device until the server successfully updates the first currently stored parking status information according to the parking status modification information.

Optionally, in a specific implementation manner, the server may be an SVN server. The SVN is a abbreviation of Subversion, is a version control system of open source code, and can be used for storing and tracking a directory (folder) and a modification history of a file.

Accordingly, in this specific implementation manner, the client installed in the client device and used for updating the parking status information is the client corresponding to the SVN server, and the client includes various command programs related to data updating.

Corresponding to the data updating method applied to the client device side provided by the embodiment of the invention, the embodiment of the invention provides a data updating device applied to the client device side.

Fig. 7 is a schematic structural diagram of a data updating apparatus applied to a client device according to an embodiment of the present invention. As shown in fig. 7, the apparatus includes the following modules:
