Description
Technical field
The utility model relates to electronic-controlled installation, particularly a kind of auto communication controller.
Background technology
At present, in auto communication controller product, major function is the volume control of voice-grade channel-Mike and earphone passage, demand along with the different raising of people's day, to the technical market more new problem has been proposed, for example: Auto Power On and shutdown, the auto-pickup of phone, hands-free and hidden conversation or the like.State when design in realization, it is discrete that the controller core circuit is generally CPU, procedure stores device, data storage device three often, and this makes that the volume of controller and cost can not be satisfactory.
The utility model content
The purpose of this utility model provides a kind of above-mentioned defective that overcomes, in auto communication, have to mobile phone various control function, high integration and all improved auto communication controller on volume and cost.
For achieving the above object, the utility model auto communication controller comprises handset port and automobile interface, also comprise power circuit, MCU chip and be connected on handset port and automobile interface between level shifting circuit and voicefrequency circuit; Level shifting circuit links to each other respectively with the MCU chip with voicefrequency circuit; Power circuit is connected between MCU chip and the automobile interface, and links to each other respectively with voicefrequency circuit with level shifting circuit; Handset port input handset communication relevant information, automobile interface inserts automobile power source, and the MCU chip has some sequences of operation that the mobile communication relevant information is sampled and controlled, and its commands for controlling signal is exported to the sound equipment passage of automobile by automobile interface.
The utility model auto communication controller wherein, also is connected to charging circuit between handset port and the automobile interface, charging circuit links to each other respectively with power circuit with the MCU chip.
The utility model auto communication controller, wherein, the employing model of MCU chip is the chip of AT89S52, this chip includes the FLASH program storage.
The utility model auto communication controller, wherein, voicefrequency circuit has Mike and two passages of earphone.
The utility model auto communication controller beneficial technical effects is: owing to adopt the MCU chip of high integration, realized in auto communication to the auto-pickup of the Auto Power On of mobile phone and shutdown, phone with hang up, hands-free and hidden conversation and to functions such as the automatic chargings of mobile phone, become all improved auto communication controller product on volume and cost.
Description of drawings
The utility model is elaborated with reference to accompanying drawing below in conjunction with embodiment.
Fig. 1 is the block diagram of the utility model auto communication controller;
Fig. 2 is the circuit diagram of the utility model auto communication controller.
Embodiment
With reference to Fig. 1, the embodiment of the utility model auto communication controller, comprise handset port 1 and automobile interface 2, power circuit 4, MCU chip 3 and be connected on handset port 1 and described automobile interface 2 between level shifting circuit 5, voicefrequency circuit 6 and charging circuit 7.Level shifting circuit 5, voicefrequency circuit 6 and charging circuit 7 link to each other respectively with MCU chip 3, and power circuit 4 is connected between described MCU chip 3 and the described automobile interface 2, and link to each other respectively with level shifting circuit 5, voicefrequency circuit 6 and charging circuit 7.
Among the embodiment of the utility model auto communication controller, the relevant information of handset port 1 input handset communication, automobile interface 2 inserts automobile power source.Power circuit 4 converts the 12V automobile power source to the needed 5V of controller circuitry, 8V output.MCU chip 3 has some sequences of operation that the mobile communication relevant information is sampled and controlled, and its commands for controlling signal is exported to two sound equipment passages of automobile by automobile interface 2.With reference to Fig. 2, it is the highly integrated chip of AT89S52 that MCU chip 3 adopts model, includes FLASH program storage and data storage, and the major function of controller is all finished by chip of MCU, and its control procedure is as follows:
After the user received mobile phone on the controller, controller was discerned the current state of mobile phone automatically, and it is arranged to hands-free working method, controlled the charging to mobile phone simultaneously, according to circumstances mobile phone was charged.If mobile phone is when having incoming call, the control Auto Power On automatically switches to the sound of earphone passage on the internal loudspeaker and controls auto-pickup, utilizes that Mike replaces the hand-free call that mobile phone Mike realizes duplex in the car.When end of conversation, control is shutdown automatically, and mobile phone is hung up automatically.In addition, can be that the volume of Mike and earphone passage and hands-free or hidden call mode are provided with to the two-way audio passage by controller.
The utility model auto communication controller adopts the design of a MCU chip to overcome control, procedure stores and the discrete defective of storage three, makes the volume of controller and cost all be improved.
