Abstract
The utility model relates to a mouse with an E-mail indicator, which comprises an existing mouse. The utility model is characterized in that the utility model is provided with an E-main indicator which is composed of a micro-controller, a detecting circuit which is connected with the micro-controller, an FSK decoder, a DTMF decoder, a COM interface circuit and a signal indicating luminous tube. A user can immediately know whether a new E-mail arrives without the need of opening a personal computet, so the utility model avoids the blindness of traditional mail inquiry on internet, reduces internet cost, and saves precious time. To a certain extent, the utility model relieves network jam.
Description
The utility model belongs to computing machine, communication and Internet technical field, specifically is a kind of mouse that has the Email indicator.
The interrelated data statistics, sending and receiving e-mail accounts for 80% of INTERNET business.And all adopt passive mode to receive Email at present, and promptly the recipient must constantly surf the Net and inquire about in oneself the mailbox, and whether just know has new mail to be sent to the mailbox of oneself.At present at home under network infrastructure development and the incomplete situation, people's inquiry mail of constantly surfing the Net will certainly cause certain network blockage.Simultaneously, constantly online inquiry Email has also brought unnecessary expenses of surfing Internet to the user if there is not new mail, not only loses time but also sink money.Mouse is the input accessory of PC indispensability, and it is with low cost, and is easy to use, but it does not possess the prompt facility of Email.
The objective of the invention is to overcome the above-mentioned deficiency of prior art, provide a kind of and do not drive PC, need not surf the Net and just can indicate the mouse that has Email (E-mail) indicator that has or not Email Information.
The mouse that has the E-mail indicator of the present utility model comprises existing mouse part, it is characterized in that: also comprise the Email indicator, described Email indicator is connected between the com port of telephone wire and computing machine.
Originally the existing mouse function of mouse collection and the Email deixis that have the Email indicator are the whole body, compact conformation, and circuit working is reliable.It has made full use of the resource of existing telecommunication system, the user is under the situation of not opening the PC online, can in the very first time, know whether new mail arrives by its Email indicator, avoided the blindness of traditional online inquiry mail, reduced expenses of surfing Internet, save valuable time, extenuated the obstruction of network to a certain extent.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the structural representation of the utility model mouse;
Fig. 2 is its schematic block circuit diagram;
Fig. 3 is the embodiment circuit diagram;
Fig. 4 is its microcontroller software groundwork process flow diagram.
Originally the mouse that has the Email indicator comprises mouse and Email indicator two parts.Fig. 1 is its structural representation, profile is close with existing mouse, the diagram part is housing (1), function key (2), mail signal lamp (3), attachment plug (4) etc., and its roller ball, roller ball sensing apparatus, mouse interface circuit and Email indicator circuit part all place in the housing.Described sensing apparatus is identical with the sensing apparatus of traditional mouse, can be resistance-type or condenser type or optical profile type or pulsed or coding type sensing apparatus.
Shown in theory diagram 2, the mouse of this band E-mail indicator comprises: microcontroller (21), be connected in the testing circuit (22) of microcontroller first input end, be connected in the FSK demoder (23) of microcontroller second input end, be connected in the dtmf decoder (23) of microcontroller Q1～Q4 end, be connected in the com interface circuit (25) of microcontroller the 3rd input end, the signal indication luminotron (LED) of microcontroller output terminal, and mouse circuit part (26); The input end of described testing circuit, dtmf decoder and FSK demoder all is connected to telephone wire by capacitance, and the control end of dtmf decoder and FSK demoder all is connected to the control output end of microcontroller.
In Fig. 3 circuit diagram, the mouse interface circuit part is by interface circuit IC5, the light emitting diode of roller ball sensing apparatus, and two function keys that are connected with interface circuit and attachment plug J2 form, IC5 adopts the SC83702B circuit in this circuit.
Testing circuit is by triode Q1, Q2, and relevant resistance R 4～R8, and some capacitor C 5～C8 form the two poles of the earth inverting amplifier, and two electric capacity of input end serial connection of first utmost point inverting amplifier are connected in telephone wire.Testing circuit is used to detect and has or not the mail signal on the telephone line, and when the mail signal occurring, its output signal LIN becomes high level, makes microcontroller enter duty.
Dtmf decoder is by decoding circuit IC2, and peripheral resistance, electric capacity are formed, its two input ends series connection capacitance C12, C13 are connected to telephone wire, after the dtmf signal that switch is sent here is decoded through decoding circuit IC2, through its output terminal (Q1～Q4) enter microcontroller to be for further processing.Described dtmf decoder adopts decoder integrated circuits such as HM9270D.
The FSK demoder is by decoding circuit IC1, and peripheral resistance, electric capacity are formed, its two input end connects the polarity switching that four diodes are formed, be connected to telephone wire by capacitor C 9, C10 again, after the fsk signal that switch is sent here was decoded through decoding circuit IC1, its output end signal DATA sent into microcontroller and is for further processing.The FSK demoder of embodiment can adopt decoding circuits such as SA9615.
The microcontroller part is the center with microcontroller IC3, can adopt chips such as W741C204.That external crystal oscillator input termination crystal oscillator (XT2) and two electric capacity (C25, C26) of microcontroller W741C204, LED signal lamp are controlled by resistance R 28 by microcontroller is bright/go out.Triode Q4 and related resistors thereof, electric capacity are formed the reset circuit of microcontroller.Triode Q3 and relevant three resistance thereof are formed battery weak electricity measuring circuit, and when cell voltage reduced to certain value, its BDET end becomes low level input microcontroller to be handled, and the LED flicker is changed, and the prompting user changes battery.
The com interface circuit is by IC circuit 4 (as MAS232), and the capacitor C 17～C21 that is connected with IC circuit 4 respective terminal constitutes, the output signal PC of circuit MAS232 sends into the PC COM port by attachment plug, it is used to realize and the communicating by letter of PC, so that the user sets the E-mail identification number on the PC of oneself.
The utlity model has the function of common mouse and E-mail signal indication.During PC work, it uses as mouse.Do not open under the situation of PC, signal and data that its automatic identification switch end sends, and the recognition data of setting with the user (E-mail identification number) is relatively, if the two is identical, then the drive signal indication LED is luminous, has new E-mail to arrive with the prompting user.
Its groundwork process such as flow process are shown in Figure 4.Connect the com port of com interface circuit to PC, energized by the microcontroller input identification code of PC to the E-mail indicating circuit, and is stored this identification code.Microcontroller monitors and has or not the input of Email signal, if the Email signal is arranged, microcontroller output control signal starts dtmf decoder or FSK decoder functions, in some second, receive data, close corresponding demoder, with the identification code comparison of the number that receives with former input, if both unanimities, the microcontroller output signal makes pilot lamp LED flicker, and prompting has the E-mail signal to send to, user's reception Email of can starting shooting.In case can also realize user's online simultaneously, LED just extinguishes, and reenters waiting status.
