Detailed Description
Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application and not all of the embodiments of the present application, and it should be understood that the present application is not limited by the example embodiments described herein.
Fig. 1 is a flowchart of a data transmission method of an intelligent charging pile according to an exemplary embodiment of the present application. As shown in fig. 1, the data transmission method of the intelligent charging pile comprises the following steps:
step 110: and acquiring the network communication state of the intelligent charging pile.
In order to collect operation data of the intelligent charging pile and charging data of a corresponding vehicle (such as an electric automobile, an electric motorcycle, an electric bicycle and the like) or a battery, and update data of the intelligent charging pile or issue data such as advertisements (audio or video data and the like), the intelligent charging pile is provided with a communication module such as a 4G, 5G or wired network and the like so as to realize the functions. However, because the setting position of the part of intelligent charging pile is remote, there may be no network coverage, such as an underground garage, and in addition, the part of intelligent charging pile may also cause the damage of the communication module of the intelligent charging pile due to long-time exposure in a severe environment. In order to avoid the problem that the intelligent charging pile can not be networked and data is lost, the application provides a scheme capable of temporarily solving the technical problem, and a detection module of a network communication state is arranged at the intelligent charging pile end to detect (can be real-time detection or detection when uploading or downloading data fails) the network communication state of the intelligent charging pile, namely, whether the current intelligent charging pile can be networked or not is determined to realize data transmission, a specific detection mode can be to send detection signals to a background server and receive feedback signals of the background server to the detection signals, if the feedback signals can be received, the network can be indicated, otherwise, the network cannot be indicated. The background server stores relevant data such as a battery, a car body, a charging pile, an inductor and the like.
Step 120: and searching and connecting communication equipment within a short distance range of the intelligent charging pile when the network communication state is that the intelligent charging pile is not connected with the network.
The communication equipment can be a carrier provided with charging application software (charging APP), such as a mobile phone and the like, and the communication equipment is connected with the intelligent charging pile when the charging application software is started so as to realize charging; after the intelligent charging pile and the electric vehicle are connected, a user starts charging by starting charging APP software in communication equipment such as a mobile phone and the like. In one embodiment, the specific implementation of step 120 may be: when the charging application software of the communication equipment is searched to be started, the communication equipment is connected in a communication mode. When the network communication state of the intelligent charging pile is not networking, namely the intelligent charging pile cannot networking, at the moment, the intelligent charging pile starts short-distance communication (such as Bluetooth communication in the frequency band of 2.45 GHZ) to search for nearby communication equipment, and when the communication equipment (the Bluetooth function of the communication equipment is in an on state) which is started or background running charging application software is searched for, the Bluetooth is connected with the communication equipment.
It should be understood that the communication device in the present application may also be other intelligent charging posts located in the same area as the non-networked intelligent charging post, and the other intelligent charging posts may be networked, and in addition, the communication device may also be other networking devices with a short-distance communication function, for example, an intelligent billboard, an intelligent charging system in a parking lot, an intelligent camera, and the like. The communication equipment in the application can also be the charger of the electric vehicle or the battery which is connected with the non-networking intelligent charging pile for charging, and the memory in the charger is used as the transfer equipment for data transmission of the intelligent charging pile, so that the data transfer transmission can be met, and the success rate of the data transmission can be guaranteed by long-time connection of the charger and the intelligent charging pile.
Step 130: and sending the uploading data of the intelligent charging pile to the communication equipment.
After the communication equipment is connected, the uploading data of the intelligent charging pile which is required to be uploaded to the background server is sent to the communication equipment in a Bluetooth communication mode and the like, so that the uploading data of the intelligent charging pile is sent to a piece of equipment capable of being networked.
Step 140: the communication equipment is controlled to send the uploading data to a background server; the background server is used for storing data of the intelligent charging pile.
In one embodiment, the specific implementation of step 140 may be: the communication equipment is controlled to send the uploading data to a background server through charging application software; or when the communication equipment is connected with the networking intelligent charging pile, the communication equipment is controlled to send the uploading data to the networking intelligent charging pile through the charging application software so as to upload the uploading data to the background server; the intelligent charging pile is in a networking state. According to the method and the device, after the uploading data is sent to the communication equipment, the uploading data can be directly uploaded to the background server of the background for storage by utilizing the network of the communication equipment through the charging APP, so that the uploading data can be timely uploaded to the background server, and the uploading data is prevented from being lost due to the fact that the uploading data is stored in the communication equipment for a long time. The application can also temporarily store the uploading data in the communication equipment after sending the communication equipment, when the communication equipment is connected with other networking intelligent charging piles (Bluetooth connection), the uploading data is sent to the networking intelligent charging piles through the charging APP, so that the networking intelligent charging piles upload the uploading data to a background server for storage, and the excessive use of the flow of the communication equipment caused by overlarge uploading data can be avoided. Specifically, when the user carries the communication equipment and passes through an intelligent charging pile that can't network, this communication equipment is connected to this intelligent charging pile that can't network to with its data transmission that needs to upload to this communication equipment, when the user carries this communication equipment again through an intelligent charging pile that can network, this intelligent charging pile that can network is connected and acquires the data in this communication equipment with this communication equipment, this intelligent charging pile that can network uploads this data to the backstage server. It should be understood that one of the two modes may be selected according to the size and importance (or urgency) of the upload data, for example, when the upload data is smaller and more important or urgent, the upload data may be uploaded to the background server in real time by using the traffic of the communication device for maintenance, and when the upload data is larger and less important or urgent, the upload data may be temporarily stored in the communication device, and the transfer of the upload data to the background server may be achieved by using the intelligent charging pile that may be networked. It should be further understood that other manners of uploading data may be selected according to the requirements of the actual application scenario, for example, the uploading data is temporarily stored in the communication device, and when the communication device is detected to be in the wireless network state, the uploading data is uploaded to the background server, so as to avoid using the data traffic of the communication device.
According to the data transmission method of the intelligent charging pile, when the network communication state is that the intelligent charging pile is not networked, searching and connecting communication equipment within a short-distance range of the intelligent charging pile, after the communication equipment is connected, transmitting uploading data of the intelligent charging pile to the communication equipment by utilizing short-distance communication, and finally controlling the communication equipment to transmit the uploading data to a background server; when the intelligent charging pile is detected that the intelligent charging pile cannot be connected with the intelligent charging pile, the communication equipment which is nearby and can be connected with the intelligent charging pile in a short-distance communication mode is searched, uploading data which need to be uploaded to a background server is sent to the communication equipment after the communication equipment is connected, the communication equipment is used as a relay ferrying device to finally upload the uploading data to the background server for storage, accordingly the intelligent charging pile can upload data in an unconnected state, the relevant data is guaranteed, the integrity of charging data of all the intelligent charging piles is guaranteed, the integrity and the authenticity of charging information of a charging vehicle are guaranteed, the full life cycle charging data of the charging vehicle are recorded, and the charging effect of the charging vehicle is improved.
Fig. 2 is a flowchart of a data transmission method of an intelligent charging pile according to another exemplary embodiment of the present application. As shown in fig. 2, after step 120, the data transmission method of the intelligent charging stake may further include:
step 150: and sending the update data in the background server to the intelligent charging pile through the charging application software.
The intelligent charging pile may need to update programs, data information or advertisement information (public welfare advertisement, etc.) in a long-time use process, for example, when a user performs charging, the charging parameters or charging curves (including charging parameters at different moments) can be freely selected, or the intelligent charging pile generates one or more preferred charging curves or charging modes in real time by identifying identity information of the electric vehicle or the battery and combining the related data of the electric vehicle and the battery downloaded by a background server for selection by the user. And the related data of the electric vehicle and the battery stored in the background server are required to be downloaded from the background server after the identity signals of the electric vehicle and the battery are identified, and at the moment, if the intelligent charging pile cannot be networked, the related data are required to be downloaded to the corresponding intelligent charging pile through charging application software in the communication equipment, and after the charging is completed, the charging data (comprising charging time, charging parameters and the like) of the electric vehicle and the battery are also required to be uploaded to the background server of the background, so that the electric vehicle and the battery can be referred to in the next charging.
Fig. 3 is a flowchart of a data transmission method of an intelligent charging pile according to another exemplary embodiment of the present application. As shown in fig. 3, the step 150 may include:
step 151: the update data is split into a plurality of update data packets.
Wherein the data amount of each update data packet is equal to or smaller than a preset update data amount threshold. In an embodiment, the specific implementation manner of step 151 may be: dividing the update data into a plurality of update data segments, generating an update check code according to each update data segment, and generating a plurality of update data packets according to each update data segment and the corresponding update check code. Because the data volume of the updated data may be larger, if the data is transmitted more frequently, the communication device may stay at the position of the intelligent charging pile for a shorter time (i.e. the connection time between the communication device and the intelligent charging pile is shorter), which may result in transmission failure. Therefore, the present application divides the update data with a preset update data amount threshold, that is, divides the update data into a plurality of update data packets equal to the update data amount threshold or further includes a data packet (typically, the data amount of the last data packet) smaller than the update data amount threshold, so as to reduce the data amount of a single data packet, thereby improving the success rate of data transmission. And generating a check code based on each updated data segment to improve the safety of data transmission, and generating a position character segment marking the position or sequence information of each updated data segment according to the position or sequence information of each updated data segment, and packaging the updated data segment, the check code, the position character segment and other information to obtain an updated data packet.
Step 152: and sending a plurality of update data packets to the intelligent charging pile through the charging application software for a plurality of times.
After obtaining the plurality of update data packets, the plurality of update data packets may be sent to the intelligent charging post in a plurality of times (e.g., one update data packet is sent at a time), and specifically, the update data packets are sent through charging application software in the communication device. After receiving the update data packets, the intelligent charging pile checks the update data packets, and after successful check, the received update data packets are determined to be correct, and after successful receipt of all the update data packets, the intelligent charging pile performs sequencing and splicing according to the position character segments in the data packets to obtain complete update data. The update data packet may be sent multiple times by the same communication device or multiple communication devices, that is, the transmission of larger update data may be realized by using multiple communication devices. If the data transmission is realized by a plurality of communication devices, the common communication device using the non-networked intelligent charging pile can be obtained through statistical analysis according to the use frequency and the use position information of the communication devices, namely, the communication device possibly reaching the non-networked intelligent charging pile in the shortest time is obtained through regular analysis according to the use frequency and the historical use time of the communication devices, and the charging probability that the communication device selects the non-networked intelligent charging pile to charge can be obtained according to the position information analysis of the intelligent charging pile historically used by the same communication device, so that the communication device which can reach and use the non-networked intelligent charging pile in the shortest time with a larger probability can be obtained, and the background server can send the data to be updated to the communication device (which can comprise one or more) to realize data updating.
Fig. 4 is a flowchart of a data transmission method of an intelligent charging pile according to another exemplary embodiment of the present application. As shown in fig. 4, the step 130 may include:
step 131: the uploading data is segmented into a plurality of uploading data packets.
The data volume of each uploading data packet is equal to or smaller than a preset uploading data volume threshold value.
In one embodiment, the specific implementation manner of step 131 may be: dividing the uploading data into a plurality of uploading data segments; respectively generating an uploading check code according to each uploading data segment; and generating a plurality of uploading data packets according to each uploading data segment and the corresponding uploading check code. Because the data volume of the uploaded data is possibly larger, if the data is transmitted more frequently, the communication equipment is likely to stay at the position of the intelligent charging pile for a shorter time (namely, the connection time between the communication equipment and the intelligent charging pile is shorter), so that the transmission is failed. Therefore, the present application divides the uploading data with a preset uploading data amount threshold, that is, divides the uploading data into a plurality of uploading data packets equal to the uploading data amount threshold or further includes a data packet (usually the data amount of the last data packet) smaller than the uploading data amount threshold, so as to reduce the data amount of a single data packet, and improve the success rate of data transmission. And a check code is generated based on each section of uploading data section to improve the safety of data transmission, in addition, a position character section marking the position or sequence information of each section of uploading data section can be generated according to the position or sequence information of each section of uploading data section, and the information such as the uploading data section, the check code, the position character section and the like is packaged to obtain an uploading data packet.
Step 132: and transmitting the plurality of uploading data packets to the communication equipment in a plurality of times.
After obtaining the plurality of uploading data packets, the plurality of uploading data packets may be sent to the communication device in a plurality of times (for example, one uploading data packet is sent at a time), and specifically, the uploading data packets are obtained through charging application software in the communication device. And after receiving all the uploading data packets successfully, the background server performs sequencing and splicing according to the position character segments in the data packets to obtain complete uploading data. The uploading data packet uploaded for multiple times can be realized by the same communication equipment or a plurality of communication equipment, namely, uploading of larger uploading data can be realized by utilizing the plurality of communication equipment.
