Client platform stopped for any reason data transfer and log out from the server platform.
3.10
Encryption encryption
Data transmission process of encryption.
3.11
Decryption deciphering
After receiving the data, the process of internet solutions password.
3.12
Assembly assembly
Real-time information of each message body part of the course of free combination.
4 General requirements
4.1 protocol structure to TCP/IP network control protocol as the underlying communication protocol bearer, as shown in FIG.
1 electric car with remote service management system communication protocol stack
Connected to the communication protocol between 4.2 platform should meet this part of Chapter 5, the provisions of Chapter 6 and Chapter 7.
4.3 vehicle terminal to the platform communication protocol should refer to Appendix B.
5 communication connection
5.1 connection establishment
Client platform initiates a connection request to the communication server platform, when the communication link connection is established, the client-side service platform should automatically
Sign in internet transmit identification information, the server platform to deal with the received data validation; when the check is correct, the server platform should
Returns success response; checksum error, the server platform should store error data records and notify the client platform. Login process shown in Figure 2
FIG.
Figure 2 platform sign a schematic flow diagram
Client platform should be completed by this sign transmitted after receiving the reply command server platform; client platform is not within the specified time
Received reply command, 1min should re-sign in each interval; after repeated three times in a row if the sign is no answer, the interval should be 30min, continued heavy
The new link and the data is not successfully transmitted before linking stored successfully resubmitted repeat sign in the interval can be set.
5.2 Information Transmission
5.2.1 client platform after a successful login, the server should be reported to the real-time information platform for electric vehicles, real-time information reporting process shown in Figure 3
FIG.
Figure 3 flow diagram information reporting
5.2.2 When a client server platform to platform reporting information, the server platform to deal with the received data validation. When the check is correct
When the server platform to do the right answer; when parity error occurs, the server platform to do the wrong answer. When answering message service client platform error, passenger
The client should resend vehicle real-time information under this section, shall be re-sent at intervals of 1min 1, failed three times longer sent.
5.2.3 Client server platform to platform reporting information, the following data should be completed in accordance with the actual situation 7.2.3. Number of drive motor
Data, vehicle data, fuel cell data, engine data and vehicle location data, extreme data, alarm data reported after assembly. Cross-platform
In other data, and user-defined data exists, data exchange platform should complete and user-defined data reporting.
5.2.4 Client server platform to platform reporting time period information should be adjusted. Maximum vehicle information reporting time period should not be
Over 30s; when a vehicle appears in Table 17 Level 3 alarm, reporting failure point in time before and after the data and information sampling period is not 30s
More than 1s, which fails before the data should be transmitted in the form of replacement.
5.2.5 When the terminal is encrypted when transmitting data, the client platform should first decrypt the data, re-encrypted and sent to the rear end of the service level
Taiwan, such as the transfer between platforms without re-encryption encryption requirement is not necessary.
Statistics reported 5.3
Statistics should be FTP, HTTP, or HTTPS transmitted to the server platform.
5.4 Disconnect
Server platform should disconnect the client platform based on the following sessions.
--- TCP connection is broken.
Client platform should be disconnected from the server platform based on the following sessions.
--- TCP connection is broken;
--- TCP connection is normal, to have not received a response after the number of retransmissions.
5.5 replacement mechanism
When abnormal data communications link, the client platform should be reported in real-time data stored locally. In the data communications link back to normal
After free time in sending real-time reporting of complete data reporting replacement data store. Replacement of data should be reported within 7 days of the communication link
During anomaly data storage, real-time data reporting format and the same data, and identifies the information reported for the replacement (0x03).
