3 Terms and definitions

The terms and definitions, which are defined in GB 17691, as well as the following terms and definitions, apply to this standard.

3.1

Enterprise platform for emission remote monitoring of heavy-duty vehicles

A platform, that is organized and constructed by heavy-duty vehicle production/import enterprises, in accordance with the technical requirements of this standard; directly collects and manages the remote monitoring data of heavy-duty vehicle emissions; transmits data to the Ministry of Ecology and Environment. It is referred to as "enterprise platform".

3.2

Data packet loss rate

The proportion of lost data packets in the total amount of sent data packets, during data transmission.

3.3

Fine-grained permission management

In addition to the rights management of data types, the platform also has rights management for data entities, such as the management of different users' access rights to different vehicle data.

4 General requirements

4.1 The enterprise platform shall have the function of receiving remote monitoring data of emissions, from the vehicle terminal, AND transmitting the data to the Ministry of

Ecology and Environment.

4.2 The enterprise platform shall ensure data security. It shall receive and store the data, from the vehicle terminal, in an encrypted way. The enterprise platform shall ensure that the data has not been modified in any way AND transmitted to the Ministry of

Ecology and Environment, in accordance with the prescribed communication protocol.

4.3 The enterprise platform shall meet the requirements of GB/T 22239, for security protection level 3 and above.

4.4 Enterprises can use two or more enterprise platforms, OR they can entrust other institutions to build and operate enterprise platforms.

5 Enterprise platform registration

5.1 Enterprises shall register, by filling in the basic information of the enterprise platform, through the vehicle environmental protection information disclosure system.

5.2 The basic information of the enterprise platform includes: the name of the enterprise platform, the number of current servers of the enterprise platform, the storage capacity (TB), the current bandwidth capacity (Mbps), etc.

5.3 After the enterprise platform is successfully registered, the data port can be obtained, which is used for the transmission of remote emission monitoring data of the vehicle of the enterprise information disclosure.

be greater than 5 s. The enterprise platform shall have sufficient storage space, to receive real-time vehicle data.

7.1.4 The enterprise platform shall transmit the received data to the Ministry of Ecology and Environment, according to the specified communication protocol. The data forwarding delay shall not exceed 10 s; the maximum data transmission period shall not exceed 10 s; the data transmission packet loss rate shall not exceed 1%.

7.1.5 The enterprise platform shall have the functions of self-check and pre-alarm, according to the relevant technical requirements of this standard.

7.1.6 If the activated on-board terminal is damaged and needs to be replaced, the enterprise platform records and transmits the vehicle static data to the Ministry of

Ecology and Environment.
