Fig. 1 is a circuit diagram of a control circuit for transmitting intercom information through a charger stand according to the present invention.
Detailed Description
For a further understanding of the structure, features, and other objects of the invention, reference should now be made in detail to the accompanying drawings of the preferred embodiments of the invention, which are illustrated in the accompanying drawings and are for purposes of illustrating the concepts of the invention and not for limiting the invention.
As shown in fig. 1, fig. 1 is a circuit diagram of a control circuit for transmitting intercom information through a charger stand according to the present invention; the control circuit comprises a main control MCU1, an MCU power supply 2, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a first diode D1, a second diode D2, a power switch S1, a charger battery E and a battery protection circuit 3 in the interphone, a charging power supply circuit 4 in the charging seat and a communication interface circuit 5 at the background end; the pin 1 of the main control MCU1 is connected with the pin 2 of the fourth resistor R4 and the pin 1 of the third resistor R3, the pin 1 of the fourth resistor R4 is grounded, the pin 2 of the third resistor R3 is connected with the positive end of the second diode D2 and the pin 1 of the charging power supply circuit 4, and the negative end of the second diode D2 is connected with the MCU power supply 2; the pin 2 of the main control MCU1 is connected with the pin 2 of the second resistor R2 and the pin 1 of the first resistor R1, the pin 1 of the second resistor R2 is grounded and connected with the pin 3 of the battery protection circuit 3, the pin 2 of the first resistor R1 is connected with the positive end of the first diode D1 and the input end of the power switch S1, the negative end of the first diode D1 is connected with the negative end of the second diode D2 and the MCU power supply 2, the output end of the power switch S1 is connected with the positive end of the charger battery E, the pin 2 of the battery protection circuit 3 and the pin 1 of the charging power circuit 4, the negative end of the charger battery E is connected with the pin 1 of the battery protection circuit 3, the pin 3 of the battery protection circuit 3 is grounded and connected with the pin 2 of the charging power circuit 4, and the pin 2 of the charging power circuit 4 is connected with the pin 1 of the communication interface circuit 5; pin 3 of the main control MCU1 is connected with pin 2 of the communication interface circuit 5.
When the interphone is plugged into the charging seat for charging after being powered off, the charging power supply circuit 4 in the charging seat supplies power to the MCU power supply 2 in the interphone through the second diode D2, the master control MCU1 detects a voltage dividing circuit connected with the third resistor R3 and the fourth resistor R4 in series, if the voltage dividing circuit is high level, the master control MCU1 judges that the interphone is plugged into the charging seat for charging, then detects the voltage dividing circuit connected with the first resistor R1 and the second resistor R2 in series, if the voltage dividing circuit is low level, the interphone is in a powered-off state, then the master control MCU1 actively initiates a communication request to the communication interface circuit 5 of the background end through a bidirectional data line, and when the background end responds to the request, communication is established between the interphone and the background end. At this time, the interphone only performs data communication with the background end and does not perform radio frequency communication.
Therefore, when the interphone is inserted into the charging seat for charging after being used, the information of the interphone can be transmitted to the background through the contact of the charging seat, and the background can modify the configuration parameters of the interphone, regardless of whether the power switch of the interphone is switched on or not. The method is convenient for the background to centrally manage and record the service time, ID number, user and the like of the interphone, and modifies the configuration parameters of the interphone, such as receiving and transmitting frequency, sub-audio frequency, transmitting power and the like.
When the interphone is not inserted into the charging seat, the power switch S1 in the interphone is closed, and the charger battery E supplies power to the MCU power supply 2 of the interphone through the first diode D1. The main control MCU1 detects that the voltage division circuit of the first resistor R1 and the second resistor R2 which are connected in series is in a high level, the main control MCU1 considers that the interphone is in a starting state at the moment, when the main control MCU1 also detects that the interphone is inserted into the charging seat for charging, the interphone is in a standby state except for data communication with a background end, and wireless communication can be carried out on the interphone at the moment.
Therefore, whether the interphone is started or not is only inserted into the charging seat, and the interphone can perform data communication with the background through the charging seat. The use of the interphones is clear through the background management software, and the frequency of the interphones can be set to quickly form the conversation groups with different frequencies. Can be used for sharing interphones, such as renting tourists in different batches in a tourist area.

Various modifications, equivalent alterations, or improvements will occur to those skilled in the art, and are within the spirit and principles of the invention.
