Description

Pulse telephon wireless paging digital information input automatic converting device

The utility model relates to a kind of novel pulse telephone radio-paging digital information input automatic transfer equipment (hereinafter to be referred as automatic transfer equipment).

At present, wireless communication system both domestic and external (beeper) has been extensive use of, and removes manually to have notified from a phone call (as 126) again compatibility automatic calling system (as 127), and the appearance of this new technology greatly facilitates the beeper user.But present automatic calling system is owing to the reason of technology, have only the voice frequency telephone could input digit information (Xing Shi code and abbreviated expression code) when using automatic calling system, for the Pulse Electric phones that use in a large number now, just can only transmit the number of that telephone set that is used for putting through automatic calling system automatically, and can not import, transmit digital information.This fatal weakness has been limited to the performance of automatic calling system performance, also gives and uses the user of automatic calling system to bring great inconvenience.

If make pulse telephone have the digital information input function the same with voice frequency telephone, have only the call mode that the pulse telephone standard is become the voice frequency telephone standard under existing conditions, this will spend a large amount of scrap build expenses.How under the prerequisite of not changing the existing telephone standard, make pulse telephone have the digital information input function the same with voice frequency telephone.This is home and abroad wireless communication system and telephone set, all insurmountable up to now technical barrier of switch manufacturer so far.

In view of the foregoing, the purpose of this utility model is a kind of novel pulse telephone radio-paging digital information input of design automatic transfer equipment, make pulse, audio frequency double-standard telephone set under situation about using as pulse telephone, just can be when using wireless communication system behind this device in case have, in hearing receiver, transmit " entering digital information " but just be transformed into the input digit information state after the cue automatically, utilize its phone just can import long number information like this, behind the digital information end of input, revert to normal pulse again automatically and be subjected to, send speech phase.Therefore just can be under the situation that does not change the telecommunication equipment standard, make the phone function of arteries and veins standard reach the said function of the telephone set input digit information of audio mode, can give full play of the function that wireless communication system itself has, give and use the beeper user of automatic calling system to bring great convenience.Thereby given the pulse telephone set system new vitality, enlarged the adaptive capacity of local telephone system, can be the telecommunications construction and save extensive fund wireless communication system.

The utility model achieves the above object by following measure:

Design a kind of novel pulse telephone radio-paging digital information input automatic transfer equipment, this device is formed a whole and is formed by switch, " entering digital information " cue identifier with unidirectional on state characteristic, information input converter with contact translation function.The input of switch links to each other with the negative pole of the local telephone of the SPC telephone exchange with reversed polarity, the output of switch links to each other with the input of " entering digital information " cue identifier, the output of identifier links to each other with information input converter input, and the changeover contact of information input converter links to each other with the pulse of pulse, audio frequency double-standard telephone set, the corresponding contact of audio conversion switch.

Its principle is as follows: insert the pulse of local telephone, audio frequency double-standard telephone set, be not the direct voltage of tens of volts on its local telephone during off-hook, behind user's off-hook, voltage on the local telephone is just reduced to the direct voltage of the three ten-day period of hot season, the while switch closure, because on the anti-phase input that is added in signal identifier of the direct voltage of this moment on the local telephone, not conducting of identifier, so the information input converter is not worked, its contact is failure to actuate, the user can dial the number of automatic calling system, after putting through automatic calling system, when automatic calling system passback such as " entering digital information " such cue, owing to be stored-program control exchange with reversed polarity, polarity of voltage on the local telephone change into " entering digital information " cue before the direct voltage of opposite polarity same magnitude of voltage, signal identifier conducting this moment, make the work of information input converter, its contact is transformed into automatically and makes pulse, audio frequency double-standard telephone set is to energy input digit information state, at this moment use the user of automatic calling system to utilize its pulse phone just can import long number information, automatically send digital information to the other side by automatic calling system, behind the digital information end of input, user's on-hook switch disconnects, the outage of information input converter, just be transformed into normally automatically and be subjected to, send speech phase, guarantee that the user is talked about and number dialing telephone call next time.This automatic transfer equipment is novel, circuit is advanced, good reliability, production simple installation, cheap, and pulse new production or just in use, audio frequency double-standard telephone set just can make the double-standard phone have same radio-paging digital information input function with audio mode under pulse standard situation after in a single day adding this device.

Below by accompanying drawing the utility model is described in detail:

Fig. 2, electrical schematic diagram

Insert the pulse of local telephone, audio frequency double-standard telephone set, be not the direct voltage of tens of volts on its local telephone during off-hook, voltage on the local telephone in a flash of user's off-hook is just reduced to the direct voltage of the three ten-day period of hot season, the K switch 1 that is connected on the local telephone negative pole simultaneously is the input that the three ten-day period of hot season negative DC voltage on the closed local telephone just enters " entering digital information " cue identifier 2 of automatic transfer equipment, because identifier is the diode D1 with unidirectional conducting, at this moment the voltage of its two ends adding is reverse, so not conducting of diode D1 is no-voltage input information input converter 3, the information input converter is not just worked, J1-4 is motionless for its contact, do not influence the user and dial automatic calling system and other phones, after putting through automatic calling system, when automatic calling system passback such as " entering digital information " such cue, owing to be stored-program control exchange with reversed polarity, polarity of voltage on the local telephone becomes and the preceding opposite polarity direct current malleation with magnitude of voltage of passback " entering digital information " cue, this positive voltage just can be through diode D1, enter the information input converter input of forming by relay J G by changeover contact, make the transducer work of information input, its contact J1-4 is transformed into automatically and makes pulse, audio frequency double-standard telephone set is to energy input digit information state, at this moment use the user of automatic calling system to utilize its pulse phone just can import the digital information of multidigit, send digital information to the other side automatically by automatic calling system.Behind the input digit end of message, user's on-hook K disconnects, 2 outages of information input converter, and J1-4 is transformed into phone normally automatically and is subjected to, send speech phase, guarantees that the user is normally talked about and number dialing telephone call next time.Thereby realize digital information input conversion automatically, therefore communication can not be affected yet.

In an embodiment, " entering digital information " cue identifier is made up of semiconductor diode, and the information input converter is formed by having multijunction relay.
