Description

A kind of program control automatic command telephone device

The utility model belongs to a kind of automatic command telephone device.

Existing patented product " crossbar system automatic command telephone system " though than phone dispatcher and computer instruction telephone system a lot of advantages is arranged, also exists volume big, the inconvenient problem of telephone relay maintenance.Also there is imported product price height in this class automatic command telephone system from external introduction, and homemade unit needs the transformation of the way, and installation and maintenance are the problem of difficulty relatively.

The purpose of this utility model is the problem that exists in the above-mentioned automatic command telephone system, provide a kind of utilize that existing subscriber exchange technology, semiconductor device make simple in structure, volume is little, the novel program controlled automatic command telephone device of multiple functional, dependable performance.

The method that the utility model is finished is the control rack that is formed the paging telephone device by SPC PBX and user's plate, relay plate, the instruction that forms the paging telephone device by the amplifier of the usefulness that amplifies, miniature relay etc. the rack that amplifies becomes a kind of new program control automatic command telephone device by these two kinds of groups.

The utility model has the advantages that: simple in structure, volume is little, low price; Existing switch technology and semiconductor device have been utilized, easy to make, dependable performance; Can conveniently set up and extraneous getting in touch, the telephone of adapted need not be changed a social system, and the user is easy to maintenance; Multiple functional, exhale except that having, the group calling, the effect of exhaling together, also have the repertoire of homemade stored-program control exchange, automatically continue the inside and outside contact of the unit of being applicable to; Easy to maintenance; The scope of application is wide, can be used for noises such as steel plant, chemical plant, textile mills, machinery plant, heavy construction building site, harbour and reach big, spacious production, the operational environments of scope such as synchronization job production line greatly, can also be used for the inside and outside contact of enterprises and institutions such as office, school, army, factory; Can replace existing subscriber exchange, automatic command machine, dual-use is a kind of desirable modernized communication equipment, can produce good economic benefit and social benefit.

Accompanying drawing is an agent structure schematic diagram of the present utility model.

Most preferred embodiment of the present utility model is: the instruction that the control rack, relay changeover contact (3) of being made of this paging telephone device subscriber exchange (PABX) and user's plate (SUb), relay plate [TR] and normally opened contact (4), amplifier (I-n) are formed this paging telephone device rack that amplifies.Relay changeover contact a ', b ' inlet that the instruction of a of the user's plate (SUb) in the control rack of paging telephone device, b line interface and instruction telephone device amplifies in the rack link, form an input port of calling out words public addressor amplifiers (I), amplify IA '-nA ', the IB '-nB ' of the normally opened contact (4) in the rack of relay plate (TR) A in the control rack of paging telephone device, the instruction of B line interface and instruction telephone device links, and forms group calling, the neat micropkonic input port of words of calling out.Calling subscriber (1) off-hook is dialled called subscriber (2), and the PABX switch is given the called ringing-current that send, ringing-current starting relay line bag (line Bao Wei draws), relay energized, relay changeover contact (3) a ', b ' change, and calling subscriber (1) gives orders or instructions, and loudspeaker (I) are broadcasted, called subscriber (2) off-hook is replied, relay changeover contact (3) restores, and calling subscriber (1) and called subscriber (2) conversation finish individual exhaling, conversed, The Calling Party Hooks On, and parts restore.

Calling subscriber (1) off-hook is dialled group calling or neat wail (one of out direction number), PABX switch relay plate (TR) forms loop, feasible IA '-nA ', IB '-nB ' multiple-contact (number of n is according to the customer requirements setting) the relay line bag energising (line Bao Wei draws) that is connected on A line and the B line, relay energized, IA '-nA ', IB '-nB ' normally opened contact closes, and caller is given orders or instructions, I-n user's loudspeaker are broadcasted, finished group calling or neat z z z cry, The Calling Party Hooks On, parts restore.
