ISO Foreword
The International Organization for Standardization (ISO) is a worldwide federation of national standardization organizations (ISO member groups) of various countries. The drafting of international standards is generally carried out through the technical committees of ISO. Each member group has the right to send representatives to participate in the technical committees of the topics they are concerned about. All governmental and non-governmental international organizations that have liaison relations with ISO also participate in the relevant work. ISO maintains close cooperation with the International Electrotechnical Commission (IEC) in all aspects of electrical standardization. The draft international standards prepared by the technical committees are distributed to the member groups for comments before being adopted as international standards by the ISO Council. According to ISO's procedural requirements, only those with more than 75% of the votes in favor can be officially published as international standards.
International Standard ISO10374 was drafted by ISO/TC104SC4 Container Technical Committee Identification and Communication Subcommittee 4. Appendix A and Appendix B of this standard are both standard appendices. 143
GB/T178941999
This standard describes the automatic identification system for containers and the method of transmitting container identification information and related required permanent information electronically to other equipment in a standardized form. The automatic equipment identification (AEI) system will facilitate document processing, energy control and communication (including electronic data processing systems). The visible identification marks specified in ISO 6346 are not affected by this standard. In the future, this standard will also be supplemented with content on modulation, coding and public protocols. Appendix B mainly describes the technical conditions that the system that meets the requirements of this standard should have. Part of the content in Appendix B is protected by patents.

In public places, the release intensity of the radiation waves of automatic identification devices should comply with the non-military radiation standards and shall not exceed the range of non-military radiation established by the country.
4.6 Technical conditions for the use of AEI system
4.6.1 Environmental conditions
AEI facilities operate under harsh environmental conditions of sea, rail and road transportation. The surface of the code plate and the code reader will be invaded by sand, dust, salt spray, oil, snow, ice and soot, and there will often be impact and vibration during handling and transportation operations. Due to long-term sunshine, ultraviolet rays and radiation, the external temperature often changes greatly in global container operations, so the temperature range of the code plate is between ~50℃ and +80℃, and the information stored should be able to remain intact even when it is between 70℃ and +85℃. The data stored in the code plate should also remain intact under the worst environmental conditions listed in the A1 tests of Appendix A of this standard (Standard Appendix). The AEI system should be able to operate normally in the electromagnetic environment formed by the normal operation of ship radar or other transportation facilities. When the maximum peak value of the magnetic field intensity reaches 50V/m60s, the information stored on the code plate should still be able to remain intact. 147
4.6.2 Normal display of code plate
GB/T 17894—1999
The normal position of the code plate and the orientation requirements for the code reader are shown in Figure 1, which shows the positions of the four code plates A, B, C and D.
a) The code plate should be displayed well in the normal position, even if the code plate is rotated by an angle θ (for example, the code plate A in Figure 1 can be displayed normally when it is rotated 20° along the axis perpendicular to the code plate plane). For different systems, the maximum value of this value is shown in Table 1.
b) The angle formed by the main axis of the code reader and the line connecting its reading center point and the midpoint of the code plate (see Figure 1) is determined by relevant facilities, such as the angle between the two legs of the port gate or the quay crane and the design of the code reader. Therefore, despite the presence of interference signals from all directions, the code plate (such as code plate D in Figure 1) should be able to display the query signal transmitted within the 20° cone angle range normally. The receiving range of the code plate signal is related to the design of the code reader. The incident signal within the 20° (||tt| ... 148

According to the requirements of this standard, the reliability of the code plate information positioned, programmed and read to the code reader should be at least 99.99%, that is, there should be no more than 1 missed read in 10,000 reads, and the accuracy of the AEI system can reach 99.9999%, that is, only 1 misread is allowed in 1 million reads.
4.6.5 Positioning of code plate
The code plate shall not extend beyond the outer corridor of the entire cabinet. It shall be a permanent facility fixed to the cabinet and shall not make the cabinet structure and integrity less than the maintenance requirements.
Only one pallet is required for each container. When the length of the container is less than or equal to 12.2m (40ft), it should be located 0.3m from the front end of the outer wall on the right side of the container (where the observer faces the door); when there are side wall corrugations, it should be located between the first and second side wall corrugations. When the length of the container is greater than 12.2m (40 ft), the pallet should be located approximately 0.3m behind the lifting position. In any case, the distance between the pallet and the middle cross section of the container cannot be greater than 5.94m (see Figures 3 and 4). h represents the external height of the container. For non-box-shaped, smooth-surfaced containers and insulated containers, the pallet should be located near the bottom corner fittings as an alternative to the aforementioned position. 5.94 (maximum)

The sensitivity of the code board is tested in accordance with the provisions of A4. The degree of influence of radio radiation waves on the human body should not only reach the allowable limit stipulated by the state, but also be as small as possible under reasonable conditions based on economic and social conditions, so that the radiation of radio rays reaches the provisions of the World Health Organization. 7 Interface
