Technical Specifications of Remote Service and Management System for Electric Vehicles - Part 3: Communication Protocol and Data Format 1 Scope This part of GB/T 32960 specifies the protocol structure, communication connection, structure and definition of data package as well as format and definition of data unit in remote service and management system for electric vehicles. This part is applicable to the communication between platforms in remote service and management system for electric vehicles; the transmission from on-board terminal to platform should also make reference to it. 2 Normative References The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 1988 Information Technology - 7-bit Coded Character Set for Information Interchange GB 16735 Road Vehicles - Vehicle Identification Number (VIN) GB 18030 Information Technology - Chinese Coded Character Set GB/T 19596 Terminology of Electric Vehicles GB/T 32960.1 Technical Specifications of Remote Service and Management System for Electric Vehicles - Part 1: General Principle 3 Terminologies and Definitions For the purposes of this document, the terminologies and definitions given in GB/T 19596 and GB/T 32960.1 and the following ones apply. 3.1 client platform the remote service and management platform for the vehicle data sender when data is exchanged between platforms 3.2 server platform the remote service and management platform for the vehicle data receiver when data is exchanged between platforms 3.3 register the process of providing platform and vehicle's static information for server platform from client platform, for the authentication of platform and vehicle identity Note: The definition of vehicle's static information is detailed in A.2 of Annex A. 3.4 upstream the data transmission direction from the client to the server 3.5 downstream the data transmission direction from the server to the client 3.6 vehicle login the client makes login authentication before uploading vehicle state information to the server 3.7 vehicle logout the client confirms from the server that the vehicle data is normal, stops transmitting and logs out from platform 3.8 platform login the client platform makes security authentication before uploading vehicle state information to the server platform 3.9 platform logout the client platform stops data transmission due to fault and logs out from server platform 3.10 encryption the process of encryption during data transmission 3.11 deciphering the process of deciphering after platform receives data 3.12 assembly the process of combining information carriers of real-time information freely 4 General Requirements 4.1 As for the protocol structure, TCP/IP network control protocol serves as the bottom communication bearer protocol, as shown in Figure 1. Figure 1 Communication Protocol Stack of Remote Service and Management System for Electric Vehicles 4.2 The connection between platforms and communication protocol shall meet those specified in Chapters 5, 6 and 7 of this part. 4.3 The communication protocol from on-board terminal to platform should refer to Annex B. 5 Communication Connection 5.1 Connection Establishment The client platform initiates a communication connection request to the server platform; after the communication link connection is established, the client platform shall automatically send login information to the server platform for identity recognition, and the server platform shall check the received data; if the data is correct, the server platform shall return successful response; if not, the server platform shall store error data record and inform the client platform. The login process is as shown in Figure 2.
