Description

The multifunction wireless beeper

The utility model is about a kind of reception and handles radio-paging information; Input information carries out mathematical computations; Input information, storage information carries out the multifunction wireless beeper of data processing.

Existing mobile telephone only is a kind of one-way communication instrument, according to a kind of being called as " the most flexible; technical most advanced; and the Chinese display type beeper with a series of characteristics " (this machine specification selected from the literal in the quotation marks, as follows) the specification introduction, this beeper of having represented existing radio-paging machine technology, on its panel, be provided with by " operating key ", comprise " switch/clear key, direction operating key, function key, reading key ", operate these keys and can read, store the information that wireless paging station that beeper receives is transmitted.Operate these keys, can position, can make " quarter-bell was rung in the time that you set " to quarter-bell " set hour and minute ".

Read the full content of above-mentioned specification, can know, existing mobile telephone is provided with a kind of information input equipment owing to textural: receive the wireless receiver of the information that transmits the wireless paging station, so just defining existing mobile telephone can only use as the one-way communication instrument.That is to say that existing mobile telephone is because the restriction of input equipment causes its function singleness.

The purpose of this utility model is to provide a kind of reception and handles radio-paging information; Input information carries out mathematical computations; Input information, storage information carries out the multifunction wireless beeper of data processing.It can not only be as the one-way communication instrument, can also carry out mathematical computations by character entry key, the own input character of operational order enter key, the computing order of setting up on the multifunction wireless beeper by the user, can carry out data processing by the own input character of user, operational order and other instructions.

The purpose of this utility model is achieved in that has set up character entry key, operational order enter key on existing mobile telephone.These keys (comprise display screen, buzzer, vibrator by the microprocessor in lead or other conductors, input/output interface, system bus and the beeper, output equipment, as follows) link, the user by these keys can input character, operational order and other instructions.

The character entry key that the utility model is provided with, operational order enter key sum are imported the needs of multiple character and instruction more than 15 when carrying out mathematical computations, data processing to adapt to.

The character entry key of the utility model setting, operational order enter key can be that a key is used more, thereby reduce the sum of key, dwindle the volume of multifunction wireless beeper.

Because the utility model has been set up character entry key, operational order enter key on existing mobile telephone.These keys link by microprocessor, the output equipment in lead or other conductors, input/output interface, system bus and the beeper, character entry key, the operational order enter key of user by setting up on the multifunction wireless beeper, can own input character, the computing order carries out mathematical computations, the user can own input character, data processing is carried out in operational order and other instructions, realized a tractor serves several purposes, made mobile telephone become a multifunction wireless beeper with radio-paging, mathematical computations, the multiple function of data-storing data processing.

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

Embodiment one:

Fig. 1 is a kind of concrete scheme according to the multifunction wireless beeper that the utility model proposes, it is provided with display screen (1), switch and pushes away/button (2), character entry key (3), function switch (4), operational order enter key (5), and these keys link by microprocessor, the output equipment in lead or other conductors, input/output interface, system bus and the beeper.

Function switch (4) is pulled to " CAL " position, the multifunction wireless beeper enters the mathematical computations operating state, in numerical key " 0 "～" 9 ", decimal key ". " and the operational order enter key (5) of this moment in can operational character enter key (3) "+,-, *, ÷ ,=, ON/C " the key input character, import operational order and carry out mathematical computations.When carrying out mathematical computations, if switch pushed away/button (2) would place " N " position or " M " position, if the wireless paging station sends paging information, the multifunction wireless beeper will send alerting signal: vibration or belling, the ongoing mathematical computations of multifunction wireless beeper can not be affected.When no longer carrying out mathematical computations, function switch (4) to be pulled to " BP " position, the multifunction wireless beeper promptly changes the radio-paging operating state over to, can read the radio-paging information of receiving.

Function switch (4) is pulled to " BP " position, the multifunction wireless beeper enters the radio-paging operating state: switch is pushed away/button (2) and be pushed into " N " position, beeper is in normal accepting state, switch is pushed away/button (2) and be pushed into " M " position, beeper is in the reception remember condition, when receiving paging information, mobile telephone is with flashing light and vibration or belling, display screen (1) demonstrates information, press switch and push away/button this moment, notifying from a phone call content will be presented on the display screen (1): switch is pushed away/button (2) and be pushed into " OFF " position, beeper is in off-mode.

The line map of the utility model embodiment one is divided into following components:

Fig. 2 is the line map of mathematical computations part.In this part, character entry key that the utility model is set up (3) (comprising numerical key " 0 "～" 9 ", decimal key ". ") and operational order enter key (5) (comprise "+,-, *, ÷ ,=, ON/C " key) totally 17 enter keies form input keyboards (6).When utilizing these key input characters, input operational order, the user carries out mathematical computations when operation, microprocessor LI-3301 (7) is delivered in the pulse of keyboard output, and microprocessor LI-3301 (7) sends to the display part through interface (8) the drive signal that data are handled back output.The mains switch interface (9) of mathematical computations part is corresponding with the mains switch interface (9) on the display part component.
