Description

Roaming phone card autodialer

The utility model relates to a kind of roaming phone card autodialer of the communications field, particularly relates to a kind of roaming phone card basic document and the roaming phone card autodialer of conversation object number conveniently to dial of storing.

Undoubtedly, electronic communication is one of greatest invention in modern age, because the prosperity of the communication technology has been shortened the distance between people and the people greatly, and really reached the ideal of no far and near distance.And because the universalness of communication network, no matter in the world any corner, the area that can lead to of communication network such as all can be by resident's communication of phone and this area, so undoubtedly, communication network be between people and the people, best communication media between state and the state, between area and the area.Because the popularity rate height, the user is many and market is huge, so driven the research and development of Related product technology, its purpose provides people's means of communication more easily nothing but, and the dealer then can make a profit by consumer's use.

In numerous telecommunications Related products, stored value card is a kind of commodity of hot topic wherein, and the type of telecommunications stored value card includes the general stored value card of simple Stored Value function or have Stored Value concurrently and the roaming phone card of international roaming function etc., and the occupation mode of aforesaid two kinds of stored value cards and inequality, general stored value card can be directly with phone number dial after inserting phone; When using the roaming phone card, then must dial earlier a certain station number, select mother tongue or foreign voice again, card number and password that subsequently must this roaming phone card of input confirm that by the time this phonecard formally dials after really errorless again.Voice and the international roaming service of so providing is provided aforesaid roaming phone, but truly has its inconvenience in operation.Its significant disadvantages is no more than keying in the quite big numeral of quantity, number have four, five yards at least as the platform dialled in earlier, select 1 yard of voice system, card number has ten complementarys approximately, password then generally is located at more than four yards, so roaming phone is stuck in before the formal dialing, promptly must key in the numeral more than 20 yards, because numeral is many, is easy to the situation that occurs dialing the wrong number.Even and finish aforementioned dialing smoothly, but follow-up international telephone number still is a lot of numeral, because numeral is many, originally promptly dials the wrong number easily, in case dial the wrong number, promptly must hang up, and the aforesaid long string dial action of recast its inconvenience and complicatedly promptly well imagine.

This shows, above-mentioned existing roaming phone card have must input yardage too much, occur dialing the wrong number very easily, cause consumer's many defectives such as inconvenience in the use and have, and the assistant officer waits to be improved, and seeks the otherwise effective technique solution.

Because the defective that above-mentioned existing roaming phone card exists, the design people actively study innovation based on abundant practical experience and professional knowledge, through constantly studying, design, and after studying sample and improvement repeatedly, creates the utility model finally.

Main purpose of the present utility model is, overcome the defective that existing roaming phone card exists, store roaming phone card basic document and the trip phonecard autodialer of object number of conversing and provide a kind of with convenient dialing, make it utilize the aforementioned manner telephone number of card number, password and most group conversation objects of storage bed number, roaming phone card in advance, can utilize the dialer conversion to produce sound signal during use to carry out simple and easy dialing.

The purpose of this utility model is realized by following technical scheme.A kind of roaming phone card autodialer according to the utility model proposes is characterized in that it includes: a microprocessor; One is connected selective function or carries out the key groups of set-up function with the microprocessor input, this key groups is to key in the telephone number of card number, password and the predetermined conversation object of roaming circuit card for the user, and is stored in the internal memory; One is located at the dial-up circuit on the aforementioned output end of microprocessor; One is located at the loud speaker of dial-up circuit output, and this dial-up circuit output connects loud speaker, can be converted to sound signal for dialing through dial-up circuit by the microprocessor output signal; One internal memory that is connected with microprocessor etc.; Said structure is combined, constitutes roaming phone card autodialer.Utilize aforesaid structural design, the telephone number of card number, password and most groups of the long string of roaming circuit card can be stored build file, only need the simple key-press action subsequently, can be rapidly and finish dialing accurately.

The purpose of this utility model can also further realize by following technical measures.

Aforesaid roaming phone card autodialer, wherein said microprocessor can external Ports, with online with the internal memory of outside, expand memory group number.

Aforesaid roaming phone card autodialer, wherein said dial-up circuit are to produce circuit by a DTMF to constitute.

The utility model compared with prior art has tangible advantage and good effect.By above technical scheme as can be known, the utility model includes a microprocessor and reaches key groups, dial-up circuit and the internal memory etc. that are connected with microprocessor; Wherein: key groups is to key in the telephone number of card number, password and the predetermined conversation object of roaming circuit card for the user, and be stored in the internal memory, the dial-up circuit output is connected with loud speaker again, can be converted to sound signal for dialing through dial-up circuit by the microprocessor output signal.Utilize aforesaid structural design, the telephone number of card number, password and most groups that can the long string of roaming circuit card stores build file, only needs the simple key-press action subsequently, can be rapidly and finish dialing accurately.Therefore the utility model provides a kind of autodialer that the roaming phone card is dialed overseas call that is easy to use, it has stored the telephone number of roaming phone card basic document and conversation object in advance, only need the simple key-press action during use, get final product the rapid and correct dialing of finishing, because all actuation of keys all are to be replaced by multiple tone signal frequently, it need not pass through tediously long dial action, event is unexpected to make mistakes in the dialing procedure of long string, so a facility, the instrument that dials fast, accurately can be provided, have outstanding effect for the use of roaming phone card and promote.No matter it structurally or bigger improvement is all arranged on the function, and have large improvement technically, and produced handy and practical effect, and have the effect of enhancement really, thereby be suitable for practicality more, really is a new and innovative, progressive, practical new design.
