Such as Fig. 1, a kind of data transmission device extended based on mobile terminal interface, including device case (not shown), PCB Plate 10 and mobile terminal plug 11, pcb board 10 are located in described device housing, also including USB port 12, USB speed-sensitive switches Chip 13, main control module 14 and storage card module for reading and writing 15, main control module 14 include main control chip 141 and memorizer 142, master control Chip 141 is used for data processing and exchange, and memorizer 142 is used for store code and data.Mobile terminal plug 11, USB connects 12, USB speed-sensitive switches chip 13, main control module 14 and storage card module for reading and writing 15 are located on pcb board 10;Mobile terminal plug 11st, USB port 12 is electrically connected with USB speed-sensitive switches chip 13, USB speed-sensitive switches chip 13, storage card module for reading and writing 15 with Main control module 14 is electrically connected.Based on mobile terminal interface extend data transmission device also include universal asynchronous receiving-transmitting interface 161, Serial communication interface 162, Serial Peripheral Interface (SPI) 163 and synchronous serial coffret 164, expand from main control chip 141.
USB speed-sensitive switches chip 13 is SGM7222 chips in the present embodiment, and main control chip 141 is NS1081 chips; In another embodiment, USB speed-sensitive switches chip 13 is FSUSB30 chips;Main control chip 141 is NS1068 chips.Based on mobile whole The data transmission device of end interface extension also includes encryption chip 17, electrically connects with main control module 14, for connecing to mobile terminal The data that mouth (Lightning interfaces, 3.1 interface of Type-C interfaces or Type-C, not shown) is transmitted are encrypted/decrypt.Base Also include LED 18 in the data transmission device of mobile terminal interface extension, electrically connect with main control module 14.It is described for indicating The working condition of the data transmission device extended based on mobile terminal interface.
USB device is divided into HOST (main equipment) and SLAVE (from equipment), only when a HOST is connected with a SLAVE Shi Caineng realizes the transmission of data.The mobile terminal interface of the mobile terminal based on iOS system is arranged to into USB-Host/USB- Device patterns, make mobile terminal as host computer.Extend and manage using USB speed-sensitive switches chip 13 and main control module 14 USB interface and equipment:USB speed-sensitive switches chip 13 and main control module 14 connect, and one side main control module 14 is opened by USB at a high speed Close chip 13 and enable the USB interface for expanding, another aspect main control module is connected with USB interface by USB speed-sensitive switches chip 13 The equipment transfering data for connecing.USB speed-sensitive switches chip 13 is extended to into several USB interface, main control module 14 is by a USB interface USB-Host/USB-Device patterns are set to, and using the USB interface after conversion as mobile terminal plug 11 and mobile terminal Connection, other USB interface are for being connected with USB device;Storage card module for reading and writing 15 is expanded from main control chip 141, is stored Card module for reading and writing 15 is for being connected with storage card;Likewise, expand from main control chip 141 universal asynchronous receiving-transmitting interface 161, Serial communication interface 162, Serial Peripheral Interface (SPI) 163 and synchronous serial coffret 164, for exchanging with corresponding external equipment Data.
Lightning and USB Type-C interfaces are mainly docked with the mobile terminal of iOS system, with the IAP2 agreements of standard Form communicated with mobile phone.Realize and the external device communication using other communication protocols, it is necessary to hardware and software Realize protocol conversion.Memorizer 142 (FLASH) stores protocol conversion code and data, memorizer 142 and 141 phase of main control chip Mutual communication, makes the mobile end connected on the USB high-speed equipment (not shown) connected in USB port 12, mobile terminal plug 11 ((SD card, TF cards etc., not shown), universal asynchronous receiving-transmitting connect the storage card connected on end (not shown), storage card module for reading and writing 15 The external equipment (not shown) of mouth 161, serial communication interface 162, Serial Peripheral Interface (SPI) 163 and synchronous serial coffret 164 Interface and protocol conversion are realized between the circuit of composition, it is achieved thereby that the exchange of communication data.
The protocol conversion includes:
Main control module 14 performs the conversion of IAP2 agreements and usb protocol, realizes that mobile terminal is connected with USB port 12 USB high-speed equipment (not shown) between mutual operation.
Main control module 14 perform IAP2 agreements be connected on storage card module for reading and writing 15 storage card ((SD card, TF cards etc., It is not shown) conversion of agreement, so as to realize the data exchange between mobile terminal and storage card, realize mobile terminal memory capacity Increase, carries out data transfer whenever and wherever possible.
Main control module 14 by mobile terminal by the data that IAP2 agreements send be parsed into universal asynchronous receiving-transmitting interface 161, The form of the data of serial communication interface 162, Serial Peripheral Interface (SPI) 163 and synchronous serial coffret 164, be sent to it is general What asynchronous receiving-transmitting interface 161, serial communication interface 162, Serial Peripheral Interface (SPI) 163 and synchronous serial coffret 164 connected sets It is standby.And by universal asynchronous receiving-transmitting interface 161, serial communication interface 162, Serial Peripheral Interface (SPI) 163 and synchronous serial biography Defeated interface 164 is packaged into the IAP2 protocol data forms of standard from the data of external reception, by the shifting being connected with mobile terminal Dynamic terminating plug 11, is communicated with mobile terminal in the form of the IAP2 agreements of standard.
Illustrate by taking synchronous serial coffret 164 as an example below:Synchronous serial coffret 164 can be set as moving State speed, arranges scope in 100K-400K, and synchronous serial coffret 164 enters main control chip 141 from the data of external reception Afterwards, the data for receiving are packaged into the IAP2 protocol data forms of standard for main control chip 141 and memorizer 142, by movement Terminating plug 11, is communicated with IAP2 protocol datas form and the mobile phone of standard;Mobile phone will after these data are received Which is considered as IAP2 protocol datas, calls the api routine of iOS system layer standard IAP2 just can be on iOS system application layer software Call these data;Mobile terminal sends data to main control chip 141 by IAP2 agreements, and main control chip 141 is by these data 164 data mode of synchronous serial coffret is parsed into, the equipment being connected with synchronous serial coffret 164 is sent to.
Universal asynchronous receiving-transmitting interface 161, serial communication interface 162, Serial Peripheral Interface (SPI) 163, USB port 12, storage Card module for reading and writing 15 is identical with data transmission procedure with 164 protocol conversion of synchronous serial coffret.
The core of the technical program is to carry out protocol conversion using main control chip 141 and memorizer 142, and different transmission are assisted The data of view are converted to the standard IAP2 protocol data based on iOS, corresponding, and the IAP2 protocol datas of iOS system are changed not The data of same type agreement are extended so as to realize the mobile terminal interface based on iOS;The agreement of type is not with different packets Head Section point, the data between each different packet header can be transmitted in a time-multiplexed manner, to prevent data collision.
For a person skilled in the art, technical scheme that can be as described above and design, make other each Plant corresponding change and deform, and all these changes and deforms the guarantor that should all belong to this utility model claim Within the scope of shield.
