Fig. 5 is the workflow block diagram of cradle of the present invention.
Fig. 6 is the circuit diagram of the step-down rectifying circuit of cradle of the present invention.
Fig. 1 is in Fig. 3,11 is step-down rectifying circuit, 12 is charge circuit, 13 is single battery charge seat, 14 for mobile phone contains the battery charge seat, and 15 is CPU (CPU), and 16 is LCD (LCD), 17 is keyboard circuit, 21 is electronic switching circuit, and 22 is the high sensitivity microphone, and 23 is amplifier circuit, 24 is the Dual Tone Multifrequency decoder, 25 are the calling testing circuit, and 26 is the Handless start-up circuit, and 27 is the caution sound generator, 28 is the Handless enable switch, and 29 is the outer handset connectivity port.
Address before Fig. 1 illustrates, repeat no more.
Referring to Fig. 2, cradle of the present invention, the mobile phone among the figure contains battery charge seat 14, is respectively power output end, sound input end, ring test side, sound output and Handless start end from top to bottom; Outer handset connectivity port 29 is respectively to contain battery charge seat 14 with mobile phone respectively to hold corresponding power input, sound output, ring output, sound output and Handless test side from top to bottom.When the mobile phone of conventional charger contains battery charge seat 14 and is connected with outer handset connectivity port 29, in the time of promptly in mobile phone is inserted in cradle, Handless testing circuit on the mobile phone, can be connected with the Handless start-up circuit 26 in the cradle, when the enable switch 28 of Handless start-up circuit 26 in opening following time, will order about mobile phone becomes the holding state of handsfree earphone for car, Handless start-up circuit 26 then connects CPU (CPU) 15, be provided with detection software in the CPU (CPU) 15, and be connected with an electronic switching circuit 21, high sensitivity microphone 22 that is linked in sequence and amplifier circuit 23 are connected with this electronic switching circuit 21, the Push And Release of CPU (CPU) 15 control amplifier circuit 23.
Aforementioned circuit is detecting the calling signal, and through judge relatively password by the human observer input be accurately after, but CPU 15 unlocking electronic switching circuits 21, the on-the-spot source of sound that picks up by high sensitivity microphone 22, contain battery charge seat 14 and outer handset connectivity port 29 exports mobile phone (mobile phone) to through amplifier circuit 23, electronic switching circuit 21, mobile phone, and utilize the wireless telecommunications networking of mobile phone to transmit, make it to be sent to the human observer place in a distant place, for the human observer telephone monitoring.
Cradle of the present invention, when mobile phone inserts, circuit by the simulation handsfree earphone for car charging modes in the cradle, when mobile phone is charged and be in the handsfree earphone for car state, with ring, the commentaries on classics of functions such as sending and receiving words is carried out by cradle, in cradle under the control of CPU, acoustic information around the automatic reception mobile phone, because the mobile phone of this moment has formed the Handless state, so mobile phone itself can ring, and the CPU in the cradle can control wouldn't be opened microphone circuit after receiving incoming call, and only unidirectional human observer is sent caution sound earlier, in the default time, input security password (this password sets in advance in CPU) with the prompting human observer, if human observer inputs password with telephone key-press, and in cradle the dual-tone multifrequency decoder decode and through CPU judge relatively more correct after, control unlatching internal microphone, and utilize mobile phone that transmission sound is gone out, monitor on-the-spot sound for human observer.
Please be simultaneously referring to Fig. 3, Fig. 4, the preferred embodiment circuit of cradle of the present invention.As shown in Figure 3, CPU 15 (89C2051) connects respectively: the electronic switching circuit 21 that is connected and composed by triode Q1 and peripheral cell; The dtmf decoder 24 that connects and composes by transistor Q3, integrated chip LC7385, transistor Q4 and peripheral cell thereof; By the calling testing circuit 25 that transistor Q5 and peripheral cell thereof etc. connect and compose, the ring test side that contains battery charge seat 14 with mobile phone is connected; And the Handless start-up circuit 26 that connects and composes by transistor Q2 and peripheral cell thereof etc., the Handless start end that contains battery charge seat 14 with mobile phone is connected.Connect and compose amplifier circuit 23 by integrated amplifier OP07, resistance R 11, R12 etc., the input of this amplifier circuit 23 connects a high sensitivity microphone 22, and the collector electrode of transistor Q1 is connected with the output of integrated amplifier OP07 in the electronic switching circuit 21.When calling testing circuit 25 detects the calling signal, and after the human observer password that CPU 15 is relatively exported by dtmf decoder 24 is accurate, CPU 15 makes electronic switching circuit 21 open (triode Q1 ends), pick up source of sound and after amplifier circuit 23 amplifies by microphone 22, export the sound output that mobile phone contains battery charge seat 14 to, be transferred to human observer through the mobile phone communication networking again, make distant place on-site monitoring for human observer.This enforcement circuit is arranged on caution sound generator 27 in the CPU 15, and the buzzing prompt tone of output exports the sound output that mobile phone contains battery charge seat 14 to through transistor Q1.
As shown in Figure 4, charge circuit 12 includes flip and flop generator that is connected to form by U1B, U1C (4093) and the voltage comparator of being made up of integrated amplifier TLC271, it is full fashionable to charge at battery of mobile telephone BT1, this comparator output signal makes flip and flop generator upset (resetting), automatically stop charging, reach the effect of automatic charging.
Referring to Fig. 6, step-down rectifying circuit 11 is traditional step-down rectifying circuits that connected and composed by transformer T2, diode bridge B2 etc., and its operation principle no longer describes in detail.
Also combination is referring to Fig. 2, Fig. 3 referring to Fig. 5, and shown in Figure 5 is the workflow of cradle of the present invention.The mobile phone that earlier mobile phone (mobile phone) is inserted cradle contains in the battery charge seat 14 (step 501); Operation Handless enable switch 28, start the Handless start-up circuit 26 in the cradle, enter the handsfree earphone for car state to impel mobile phone, and make mobile phone ring, be subjected to words, send the words function, replace by external device (ED) (cradle), to finish accurate monitoring (step 502); And when the human observer calling, then produce buzz (BEEP sound), inform that human observer inputs password (step 503,504,505,506) in the given time; Behind human observer input password, further judge and assert this password whether correctly (step 507); Do not hang up the telephone as password bad and human observer, then execution in step 505 is once more sent caution sound and is pointed out its input password (step 510); If human observer has been hung up the telephone and has then been returned back to initial state (step 511).
After judging that the identification password is correct, CPU 15 will control electronic switching circuit 21, the on-the-spot sound that high sensitivity microphone 22 is picked up, after amplifier circuit 23 amplifies, through mobile phone contain battery charge seat 14, outer handset connectivity port 29 is sent in the mobile phone, and transfer to the human observer place by the mobile phone communication networking, make human observer carry out phone on-site monitoring (step 508) in a distant place; And,, reply initial state (step 509) to close the output channel of high sensitivity microphone 22 and amplifier circuit 23 in its monitoring back control electronic switching circuit 21 of hanging up the telephone that finishes.
In sum, cradle of the present invention, microphone with dual-tone multifrequency decoder and high sensitivity pickup, make charger for mobile phone can utilize the transmission of mobile phone communication networking, obtain the effect of distant place wireless monitor, and mobile phone forms the Handless state simultaneously in charging, original incoming call ring and send words function by 22 replacements of high sensitivity pickup microphone, so the characteristics of on-the-spot good concealment are arranged, and do not monitored the restriction of distance and time.
