9、ization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been establish
10、ed has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
11、 International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Pu
12、blication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such paten
13、t rights. ISO 17532 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 19, Agricultural electronics. BS ISO 17532:20071Stationary equipment for agriculture Data communications network for livestock farming 1 Scope This International St
14、andard specifies a protocol for the automatic and interactive communication and control of computer systems used in livestock production. It supports communication within the livestock production as well as across the Internet. While it defines the basic protocol for data exchange, it uses generic d
15、ata structures so that the protocol is extendable regarding future requirements. The protocol is applicable only to simple and/or clearly defined entities. This International Standard deals with the networking of those services used for livestock production which are provided by the devices in syste
16、ms. It is not applicable to communication within subsystems. The syntax of the transported data is based on the ADIS and ADED standards as defined in ISO 11787 and ISO 11788; alternatively, XML/ADED can be used as described in this International Standard. Like the ADIS standard specified in ISO 1178
17、7, it is implicit that the syntax is not intended for real-time data interchange. 2 Normative references The following referenced documents are indispensable for the application of this document.

41、g. feeding and climate), environmental balance (field yard balance), and comprehensive environmental and animal protection, as well as for economic reasons. In order to use services over a networked infrastructure, information must be transported. For this, the way in which the information is to be
42、communicated between the communication partners needs to be known in advance. The purpose of this International Standard is to provide a protocol that serves this need. IP is used as the basis for ISO 17532 communication and TCP streams are used to ensure reliable communication. For management and s
43、hort messages, UDP datagrams are multicasted. For the notation of the description of the ADIS syntax, see ISO 11787. As the physical layer for the IP, the Ethernet as defined in IEEE 802.3x is the most commonly used today, and this International Standard is designed to support it. IP packets can be
44、transported using wired or wireless communication. This International Standard defines the requirements for the physical connections and the data communication in a network used for livestock production. The requirements apply for the devices connected directly to this network. 6 Technical requireme
45、nts and recommendations 6.1 Basic requirements Fast data communication between the components shall be guaranteed by the devices involved. If real-time communication is needed, logical separated network segments shall be configured for communication in real time within the important segment. A struc
46、tured cabling or wireless connection shall be provided. 6.2 Connectors The use of RJ45 connectors is recommended. Depending on the environmental conditions (light or heavy duty), the connections shall comply with protection classes IP 20 or IP 67 in accordance with IEC 60529. BS ISO 17532:200776.3 C
47、ables The devices of the manufacturers shall be star, bus or ring-shaped connections. A four-wire cable is sufficient for the data connection. For the wiring of the stable net, cable types corresponding to the IAONA recommendations (PIG, release 4.0, 2003) should be used. The transmission speed is d
48、etermined as a minimum of 10 MB/s for copper wire connections. For the wiring within the barn area, safety class system IP 67 (heavy duty) should be used. In less susceptible environments (stable office), IP 20 (light duty) is sufficient. As basic requirements for the physical layer, the recommendat
49、ions of the IAONA shall at least be met. 6.4 Transport protocol Both TCP/IP and UDP are used TCP/IP for reliable connections, UDP for multicast addressing communication. Components (WLAN, Bluetooth devices) that can be connected to the farm network via TCP/IP and UDP, and which conform to corresponding IEEE standards, are supported. Figure 1 shows this architecture graphically. Figure 1 ISO 17532 and TCP/IP layers 7 Network livestock farming communication 7.1 Farm use There are no limitations on ISO 17532 communication wit
