25、 The majority of broadcasting transmitting stations are designed and constructed to operate unattended, that is without personnel being present in the same room as the transmitter. Normally, supervisory equipment is installed which continuously monitors and sometimes controls the operation of the tr
26、ansmitters. The supervisory equipment may range from a simple unit which merely extends indications and controls into an adjacent room, to a highly sophisticated system enabling a large number of transmitters to be controlled from a common point. This standard is concerned with the interface between
27、 the transmitters and supervisory equipment. It comprises two parts: Part 1: Interface standards for systems using dedicated interconnections; Part 2: Interface standards for systems using data bus type interconnections (under consideration). It seems appropriate to divide the standard in this way b
28、ecause, although the majority of existing transmitters employ wired interconnections, the advent of microprocessors and software techniques will require different interconnection methods, for example, by means of optical fibres. 1 Scope This standard is applicable to all classes of transmitters for
29、sound and television broadcasting. The standard may not, however, be appropriate for low power equipment and certain special purpose transmitters. Any facilities and interconnections not directly associated with the transmitters, for example intruder alarms, mast lighting, etc., are excluded from th
30、is standard. 2 Object This standard deals with the interface between a transmitter (or system of transmitters) and the supervisory equipment which is intended to remotely monitor and/or control the transmitter(s). It details the interconnections and facilities to be provided with a view to achieving
31、 compatibility between different types and makes of transmitters and supervisory equipment. Section 1. General 3 Terminology To ensure a common understanding of terms used in this standard, a glossary and index have been included in Appendix A and Appendix B. The relationship between some of the mos
32、t important terms is shown in Figure 1, page 13. 4 General philosophy In order to achieve standardization, it is necessary to adopt a general philosophy, the main concepts of which are as follows: a) A basic (single) transmitter should contain its own logic to enable it to operate in its own right i
33、f no additional or reserve transmitters are required. b) Any transmitter system (an example of which is shown in Figure 2, page 14, should comprise two or more basic transmitters. c) Control and operation of a system of transmitters should be exercised by means of separate system logic. d) The inter
34、faces of both the basic transmitter and the system logic unit need to be standardized in order to ensure compatibility and interchangeability of equipment. 5 Interfaces The interfaces to be standardized are shown in Figure 2. Commands and indications are sent from and received by the supervisory equ
35、ipment, via dedicated pairs of wires connected to dedicated interface terminals or connectors on the transmitter or system logic unit.

36、this standard relates to the transmitter and system logic interface terminals and not to the supervisory equipment, although this must, of course, be compatible. 6 Command and indication circuits The term “command circuit” is used throughout this standard to denote the (dedicated) circuit required t
37、o send each command to the transmitter. Similarly, the term “indication circuit” is used to denote the circuit by means of which each indication is sent from the transmitter. 7 Transmitter systems A wide variety of transmitter systems may be devised using the approach referred to in Clause 4. Transm
38、itter systems in common use are: single transmitter (in the case of television, comprising a vision and sound transmitter operating together); passive reserve system; active reserve system; (N + 1) reserve system; multiplex reserve system. Examples of such systems are shown in Figure 3, page 15. Man
39、y minor variations of these systems are possible but the diagram indicates the most important features of each. Sections 2 to 5 below are concerned with the facilities to be provided for each system, distinguishing between binary and analogue techniques. General requirements relating to all systems
40、are given in Section 6. Section 2. Standard binary interface techniques 8 Introduction This section deals with the three main techniques in common use in systems employing binary techniques and dedicated interconnections, viz, relays; semiconductor logic; opto-isolators. 9 Relay techniques The use o
41、f relay techniques is illustrated in Figure 4, page 16. This shows the principle that the low voltage supply for command circuits is part of the transmitter and similarly, the supply for indication circuits is part of the system logic unit (or supervisory equipment in the case of a single transmitte
42、r). The low voltage supply should preferably be connected to the relays via a link external to the transmitter, as shown in Figure 4. This arrangement facilitates compatibility with different types of supervisory equipment. 9.1 Commands Commands are sent to the transmitter by means of contacts locat
43、ed in the supervisory equipment or system logic unit. The transmitter logic shall be compatible with one or the other of the following two techniques: 1) Continuous closure of the appropriate contact of the supervisory equipment or system logic unit for the duration of the required state. The opposi
44、te state is achieved by opening the contact and in this case, only a single command circuit is required. 2) Momentary closure of the contact with a duration between 100 ms and 500 ms. In this case, the opposite command requires an additional command circuit. Unintentional continuous closure of conta
45、cts which are intended for momentary closure shall not interfere with the normal operation of the transmitters.

46、nals shall be earth-free and arranged so as to allow for either: independent pairs, or the use of a common return wire. Command circuit relays shall have a nominal voltage of 24 V and a maximum energizing current of 25 mA. It is recommended that the relays should be compatible with semiconductor log
47、ic techniques and opto-isolator techniques in accordance with Clauses 10 and 11. 9.1.2 Contact requirements Command circuit contacts shall be floating, i.e. free of all potentials. The contacts shall be capable of switching at least 25 mA at 24 V d.c. 9.2 Indications As can be seen in Figure 4, page
48、 16, indications are sent to the supervisory equipment or system logic unit by means of change-over contacts located in the transmitter. 9.2.1 Contact requirements Either the normally open or normally closed contacts may be used. The contacts shall be floating, i.e. free of all potentials, and opera
49、te continuously for the duration of the indicated status. The contacts shall be capable of switching at least 25 mA at 24 V d.c. 10 Semiconductor logic techniques The principle of semiconductor logic techniques is illustrated in Figure 5, page 17. Appropriate precautions shall be taken to prevent misoperation as a result of unwanted voltages on the interconnections between the transmitter and the supervisory equipment or system logic unit. 10.1 Commands Commands are sent to the transmitter by means of semic
