Description of the drawings
Fig. 1 is the circuit diagram of the control circuit that intercommunication machine information is transmitted by charger seat of the present invention.
Specific implementation mode
It is attached in conjunction with appended preferred embodiment in order to further appreciate that structure, feature and the other purposes of the present invention
With attached drawing, detailed description are as follows, this attached drawing embodiment described is only used to illustrate the technical scheme of the present invention, and non-limiting
Invention.
As shown in FIG. 1, FIG. 1 is the circuit diagrams of the control circuit that intercommunication machine information is transmitted by charger seat of the present invention；
The control circuit include main control MCU 1 in intercom, MCU power supplys 2, first resistor R1, second resistance R2,3rd resistor R3,
4th resistance R4, the first diode D1, the second diode D2, power switch S1, battery charger E and battery protecting circuit 3, fill
The communication interface circuit 5 of charging power source circuit 4 and background end in electric seat；Wherein, the pin 1 and the 4th resistance of main control MCU 1
The pin 1 of the pin 2 of R4 and 3rd resistor R3 connect, and the pin 1 of the 4th resistance R4 is grounded, the pin 2 of 3rd resistor R3 and the
The positive terminal of two diode D2 and the pin 1 of charging power source circuit 4 connect, and negative pole end and the MCU power supplys 2 of the second diode D2 connect
It connects；The pin 2 of main control MCU 1 is connect with the pin 1 of the pin 2 of second resistance R2 and first resistor R1, the pin of second resistance R2
1 is grounded and is connect with the pin of battery protecting circuit 33, the positive terminal and electricity of the pin 2 of first resistor R1 and the first diode D1
The input terminal of source switch S1 connects, and the negative pole end and MCU power supplys 2 of the negative pole end of the first diode D1 and the second diode D2 connect
It connects, the output end of power switch S1 and the positive terminal of battery charger E, the pin 2 and charging power source circuit of battery protecting circuit 3
4 pin 1 connects, and the negative pole end of battery charger E is connect with the pin 1 of battery protecting circuit 3, and battery protecting circuit 3 draws
Foot 3 is grounded and is connect with the pin of charging power source circuit 42, the pin of the pin 2 and communication interface circuit 5 of charging power source circuit 4
1 connection；The pin 3 of main control MCU 1 is connect with the pin 2 of communication interface circuit 5.
When insertion cradle is charged after intercom shutdown, the charging power source circuit 4 in cradle passes through the two or two
Pole pipe D2 is powered the MCU power supplys 2 in intercom, and main control MCU 1 detects 3rd resistor R3 and concatenated point of the 4th resistance R4
Volt circuit then judges that intercom has been inserted into cradle and has charged if it is high level, and main control MCU 1 detects first resistor R1 again
With the concatenated bleeder circuits of second resistance R2, then illustrate that intercom is to be in off-mode if it is low level, then main control MCU 1
Communication request is actively initiated to the communication interface circuit 5 of background end by bidirectional data line, it is when background end respond request, then right
Say that machine is communicated with background end foundation.At this time intercom only with background end into row data communication without radio communication.
It therefore, can be intercom by the contact of cradle when being inserted into cradle charging after the completion of intercom use
Information is transmitted to backstage, and backstage can modify to setting for intercom with parameter, no matter whether intercom power switch connects
It is logical.Convenient for backstage manage concentratedly record intercom usage time, ID number, user etc., and to intercom set with parameter into
Row modification, such as transmitting-receiving frequency, infrasonic, transmission power.
When intercom is not inserted into cradle, power switch S1 is closed power switch S1 in intercom, charger electricity
Pond E powers to the MCU power supplys 2 of intercom by the first diode D1.Main control MCU 1 detects first resistor R1 and second resistance
The concatenated bleeder circuits of R2 are high level, then main control MCU 1 thinks that intercom is in open state at this time, when main control MCU 1 is also examined
Measure intercom and be inserted into cradle when being charged, other than intercom and background end are into row data communication, intercom also in
Standby mode, at this time intercom can carry out wireless communication.
Therefore, if intercom in spite of booting be inserted into cradle in, intercom can by cradle with backstage into
Row data communication.Just understand being used for those intercoms by the management software on backstage, quick group of intercommunication unit frequency can be set
The phone group of net composition different frequency.It can be used for sharing intercom, the tourist that different batches are such as rented in tourist district uses.
It is to be understood that foregoing invention content and specific implementation mode are intended to prove technical solution provided by the present invention
Practical application should not be construed as limiting the scope of the present invention.Those skilled in the art are in spirit and principles of the present invention
It is interior, when can various modifications may be made, equivalent replacement or improvement.Protection scope of the present invention is subject to the appended claims.
