Abstract
The utility model discloses a GSM (Global System for Mobile Communications) public card telephone which comprises a central processing unit and is characterized in that the central processing unit is connected with a keyboard, an antenna, a receiver, a display, a card reader and a power supply respectively. The telephone is always at the standby state, and a call can be made after an SIM card is inserted, thus shortening the initialization process; each SIM card corresponds to one phone number, so that network operators can know the numbers of users clearly according to the numbers of the sold SIM cards; and during calling, the SIM card realizes talking connection through the antenna and is charged automatically, and after the expenses are used up, recharging can be conducted to realize the reuse of the SIM card.
Description
Technical field
The utility model relates to a kind of telephone set, specifically, relates to the public cassette telephone set of a kind of GSM.
Background technology
Existing public telephone system all should be the structure that adopts the IC phonecard to insert, and can give timing during connection and deduct expense in this IC phonecard, but the expense button can't reuse after intact again, can not replenish continuous value.In addition, it is charged at first to start telephone set when utilizing the IC telephone set to make a phone call, and then, restarts phonecard and makes a phone call, and initialization procedure is slower.In addition, existing public telephone system all should be to adopt the IC telephone set that line access mode is arranged, and needs special messenger's cloth telephone wire during installation, can occur the phenomenon of free call on somebody else's expense through illegal means in the use, and the failure rate of circuit is also than higher, and is subject to thunderbolt and damages.This is the deficiencies in the prior art part.
The utility model content
The technical problems to be solved in the utility model provides a kind of the recycling and the initialization procedure public cassette telephone set of GSM faster.
The utility model adopts following technological means to realize goal of the invention:
The public cassette telephone set of a kind of GSM comprises CPU, and it is characterized in that: described CPU connects keyboard, antenna, receiver, display, card reader, power supply respectively.
As the technical program is further limited, be provided with CPU in the described central processor unit, described CPU connect radio circuit, voicefrequency circuit, circuit of display driving, card-reader driver program circuit, memory, keyboard drive circuit, power management module, reseting module and parameter be provided with module.
As the technical program is further limited, described card reader is the SIM card reader.
As the technical program is further limited, described CPU also connects the SIM card seat, and described SIM card seat is provided with built-in SIM card.
As the technical program is further limited, also be provided with reserve battery on the described CPU.
Compared with prior art, advantage of the present utility model and good effect are: telephone set of the present utility model is in holding state always, after the insertion SIM card, can call, and has shortened the initialization flow process; The corresponding telephone number of each SIM card, according to the quantity of the SIM card of selling, Virtual network operator can be known their number of users, when making a phone call, SIM card utilizes antenna to realize that conversation connects, and can deduct fees automatically, after the expense button is intact, can supplement with money, realize recycling.This machine is the GSM fixed wireless telephone, can install, move at the anywhere in the wireless carrier network coverage, has widened the coverage of operator, has promoted the service image of operator; The design of employing large-screen shows date on the screen and the time; Need not wiring, install convenient rapidly, promptly open promptly logical, aesthetic in appearance generous; It has overcome the public words of fixed network and has been subjected to all multifactor restrictions such as circuit, and communication line often breaks down, and is subject to the thunderbolt damage.
Description of drawings
Fig. 1 is the structure principle chart of the utility model preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment the utility model is done further to describe in detail.
Referring to Fig. 1, the utility model comprises CPU, keyboard, antenna, receiver, display, card reader, power supply, reserve battery.Described CPU connects keyboard, antenna, receiver, display, card reader, power supply and reserve battery respectively.Be provided with CPU in the described central processor unit, described CPU connects radio circuit, voicefrequency circuit, circuit of display driving, card-reader driver program circuit, memory, keyboard drive circuit, power management module, reseting module and parameter module is set.Described parameter is provided with module can realize lock machine, pintle hook lock, interlocking of phone and card, can lock operator, can lock the sub-district, and forbidding time period or the like can be set.Described card reader is the card reader of external SIM card, during use, external SIM card is inserted card reader, dial by keyboard, display shows the number of current broadcast, and external SIM card utilizes antenna to realize call function, cost of the phone call is from opening one's mouth deduction, and is very convenient.
CPU of the present utility model also can connect a SIM card seat, on the described SIM card seat built-in SIM card is set, after the telephone set energising, built-in SIM card just can be utilized the antenna search network, display display network operator name, can receive calls or dial Emergency Call this moment, for example, 110,119 etc., if insert external SIM card, telephone set can switch to external SIM card, and antenna is search network again, at this moment, can call or receive calls.This kind telephone set both can be used as public telephone and had used, also can be for family use, and very convenient.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model also is not limited only to above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also belong to protection range of the present utility model.
