GIS technology adopts geographic model analysis methods to provide geographical location information of new energy vehicle charging piles in space, and combines mobile map software to display routes in the form of geographic graphics.

[0045] In the wireless communication module, consumers use their personal mobile phones to bind their real identity information, car license plate number, mobile phone number and online banking card data, and match the mobile phone's Bluetooth with the new energy vehicle charging pile's Bluetooth by turning on the phone's Bluetooth. The wireless communication module is realized by a wireless communication network based on Bluetooth technology and interface transmission technology. Through the Bluetooth device on the user's mobile phone, the Bluetooth of the new energy vehicle used is activated, and Bluetooth matching of the kernel protocol layer LMP signal is performed. At the same time, the mobile phone's Bluetooth is used to match the Bluetooth of the new energy vehicle charging pile using the TCP protocol layer. After matching and connecting with each other, the mobile phone is used to select the charging mode of the new energy vehicle. Among them, the device information connected to the user's mobile phone and personal information are connected through the wireless network to the interface of the cloud server in the background quick management system of the new energy vehicle charging pile, and the information is uploaded through encryption.

[0046] The data encryption transmission module is used to encrypt the information uploaded by consumers and distributed charging piles and transmit it to the control terminal. The data encryption transmission module adopts symmetric key algorithm encryption processing. The symmetric key algorithm encryption processing is to encrypt the real data information uploaded by the user's mobile phone using the RSA encryption algorithm for data transmission.

[0049] Charging management module: controls the charging pile to charge the car according to the charging strategy;

[0050] Charging protection module: used to cut off power in time to protect the charging pile and the car when charging is abnormal;

[0054] Distributed charging piles, the locations of distributed charging piles are relatively fixed, and their location information can be pre-configured and stored in the control terminal.

[0055] The monitoring module is a monitoring camera installed at each distributed charging pile. The data captured by the monitoring camera is uploaded to the cloud storage module on the cloud computing unit through the communication module, which is convenient for staff to retrieve.

[0056] The modules use a wireless communication local area network to realize data transmission, the modules use a port protocol to match and transmit data, and the computer is used to edit the code of the shared memory to realize data sharing between modules.

[0057] Second implementation mode: The present invention also discloses a highway charging pile management method based on cloud computing, which specifically includes the following steps:

[0058] Step 1: First, several new energy vehicle charging piles are networked and connected with GIS technology and network communication technology to form a software architecture hardware control system for the background management of new energy vehicle charging piles;

[0059] Step 2: Based on the software system, when using a new energy vehicle charging pile, the user uses the map APP in the mobile phone to locate and find the nearest new energy vehicle charging pile, and uses the Bluetooth wireless connection to connect to the new energy vehicle charging pile to perform user identity recognition, mobile phone number and car license plate identification information to log in to the mobile phone applet to replace the use of card readers and IC cards;

[0060] Step 3: The user's registered login data is encrypted by the mobile applet's wireless communication and uploaded to the cloud server for the management of the background data of the new energy vehicle charging pile. The encrypted data is to ensure that the user's real information is not leaked;

[0061] Step 4: The control terminal receives the information uploaded by the user, and gives different charging strategies for different vehicles based on the historical data stored in the cloud and the vehicle data uploaded by the user, and intelligently controls the charging status of the distributed charging piles, so that the distributed charging piles can charge the corresponding new energy vehicles;

[0062] Step 5: At the same time, the cloud computing model module adopts modeling and simulation technology, artificial intelligence and Internet of Things technology. By simulating the data of the operating status of the new energy vehicle charging pile, a dynamic model of the physical charging pile is constructed, and then the PHM algorithm is used to monitor the operating status of the charging pile in real time and analyze faults. The constructed visual digital model is fed back to the consumer user's mobile phone in the form of dynamic graphics and text, which can realize human-computer information interaction. At the same time, consumers can query data on car charging consumption and pay electricity bills through their mobile phones.

[0063] The third implementation method: The RSA encryption algorithm generates two keys based on the theoretical basis of reversible modular exponentiation. The encryption process steps are as follows: first, select two largest prime numbers p and q of the same length, calculate their product n, n = p × q, then randomly select the encryption key e, so that e is relatively prime to (p-1) and (q-1), and finally use the extended Euclidean algorithm to calculate the decryption key d, which satisfies (mod(p-1) × (q-1)). Then In the formula, e and n are public keys, and d is a private key. Asymmetric keys have large computational complexity, but high encryption accuracy and are not easy to leak personal information. The asymmetric key algorithm is used to protect the personal information of consumers from being leaked and misused.

[0064] The computer editing code is as follows:

[0065] RSACryptoServiceProviderrsa=newRSACryptoServiceProvider();

[0066] byte[] cipherbytes;

[0067] rsa.FromXmlString(publickey);

[0068] cipherbytes=rsa.Encrypt(Encoding.UTF8.GetBytes(str),false);

[0069] returnConvert.ToBase64String(cipherbytes), which has the function of hiding the real information of consumers and encrypting with high accuracy.
