The work of preparing International Standards is normally c
11、arried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the wor
12、k. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires
13、 approval by at least 75 % of the member bodies casting a vote. International Standard IS0 11787 was prepared by Technical Committee iSO/TC 23, Tractors and machinery for agriculture and forestry, Subcom- mittee SC 19, Agricultural electronics. Annexes A and B of this International Standard are for

17、Data interchange between management computer and process computers - Data interchange syntax 1 Scope This International Standard provides the means to enable communication between on-farm process computers of stationary and mobile agricultural equipment or machinery, and management comput- ers. It t
18、herefore specifies an Agricultural Data Inter- change Syntax (ADIS), to exchange data electronically. It implies that the syntax is not intended for real-time data exchange. ADIS may be used (see figure 1) for direct data ex- change between process computer and management ADIS may also be used for d
19、ata exchange between process computer and interface software of the process computer on the PC. Alternatively for this exchange, manufacturer-specific methods can be and are used for data exchange be- tween the interface software for the process com- puter on the PC and the management program. NOTE
20、2 This does not mean that ADIS cannot be used for other data interchange. Many farmers use a method similar to ADIS to exchange data between management computers and external computers: ADIS can be used for data interchange to external computers. ADIS can also be used to exchange data between indepe
