Description

A kind of intelligent terminal

Technical field

The utility model belongs to terminal device field, relates in particular to a kind of intelligent terminal.

Background technology

Smart machine design produce and follow-up use procedure in, if need to understand the instant messages of smart machine operation, need research staff to debug to pinpoint the problems and correct consulting is provided to smart machine, thereby deal with problems fast and effectively, yet the finished product printed circuit board (PCB) of smart machine and finished product smart machine are when debugging, the transmission line of printed circuit board (PCB) need to be carried out to data receiver by being connected to fly line on beta version, thereby test, because the smart machine of finished product does not allow to increase independent debugging interface, now for finished product machine, need to dismantle bonnet and connect fly line.

Utility model content

The utility model aims to provide a kind of terminal device with single-pole double-throw switch (SPDT), by the transmission line of terminal device is connected on single-pole double-throw switch (SPDT), the ID pin of multiplexing USB (universal serial bus) and ID line passage, collecting test data, complete data acquisition when intelligent terminal is tested by multiplexing ID line.

The utility model embodiment realizes like this, a kind of intelligent terminal, described intelligent terminal comprises USB (universal serial bus) and main control chip, wherein USB (universal serial bus) is connected with main control chip, between described USB (universal serial bus) and main control chip, also comprise a single-pole double-throw switch (SPDT), the not moved end of described single-pole double-throw switch (SPDT) is connected with the ID pin of USB (universal serial bus), and the moved end of described single-pole double-throw switch (SPDT) is connected with Uart Tx pin and is connected with the ID pin of main control chip respectively.

Further, described single-pole double-throw switch (SPDT) adopts crystal single-pole double-throw switch (SPDT).

Further, between described main control chip and single-pole double-throw switch (SPDT), by I/O interface, be connected.

The utility model embodiment is by a kind of intelligent terminal, in the situation that not needing finished product intelligent terminal to tear machine open or connect fly line, just can test intelligent terminal, by multiplexing ID line, complete data acquisition when intelligent terminal is tested.

Accompanying drawing explanation

Fig. 1 be the utility model embodiment provide by single-pole double-throw switch (SPDT), obtain the schematic diagram that intelligent terminal sends information.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

The utility model embodiment utilizes a kind of intelligent terminal, as shown in Figure 1, intelligent terminal comprises main control chip 101, USB (universal serial bus) 102, main control chip is connected with USB (universal serial bus), at main control chip, be connected and comprise a single-pole double-throw switch (SPDT) with USB (universal serial bus) bus interface, single-pole double-throw switch (SPDT) not moved end is connected with the pin of the ID end line of USB (universal serial bus) bus interface, the moved end of single-pole double-throw switch (SPDT) connects respectively ID end pin and the Uart Tx pin of main control chip, when wherein Uart Tx leads ends is used for intelligent terminal to test, send the data message of test, data while testing by Uart Tx short receptor, preferred USB (universal serial bus) bus USB(Universal Serial Bus in embodiments of the present invention wherein) interface adopts Mini USB interface or Micro USB interface, because Mini USB interface or Micro USB interface have ID pin, main control chip in being connected with USB (universal serial bus) wherein four lines as standard USB wiring, use, the transmitting test data of the ID line by multiplexing USB.Single-pole double-throw switch (SPDT) is placed in to Uart TX end when needs are tested, by the channel transmission data of ID line, when normal use, single-pole double-throw switch (SPDT) is placed in to USB ID end, wherein in embodiments of the present invention, preferred single-pole double-throw switch (SPDT) adopts crystal single-pole double-throw switch (SPDT), to single-pole double-throw switch (SPDT), can adopt external physical button to control switching, also can control by main control chip and the direct-connected I/O interface of single-pole double-throw switch (SPDT).

When adopting I/O interface to control selection single-pole double-throw switch (SPDT) to be connected to Uart Tx pin, intelligent terminal transfers out detecting information by Uart Tx pin, be transferred to USB (universal serial bus) 102, USB (universal serial bus) 102 is connected by USB interface with connecting line 201, connecting line is transferred to signal the USB (universal serial bus) 301 of test board again by USB (universal serial bus), USB (universal serial bus) 301 is isolated standard USB interface signal by signal, standard USB interface signal is connected with USB (universal serial bus) 302, between USB (universal serial bus) 302 and computer 401, setting up cable data is connected, the test signal that the USB (universal serial bus) 301 of test board sends ID circuit is processed by RS232 chip 302, afterwards the signal after processing is sent to computer 401 by Serial Port Line, computer can by with USB (universal serial bus) 302 between set up be connected the running status collecting while showing intelligent terminal test.

The utility model embodiment is by a kind of intelligent terminal, a kind of terminal device with single-pole double-throw switch (SPDT) is provided, transmitted signal pin when by the test of terminal device is connected on the moved end of single-pole double-throw switch (SPDT), intelligent terminal can pass through ID pin and the ID line passage of the multiplexing USB (universal serial bus) of single-pole double-throw switch (SPDT), thereby when testing, do not need intelligent terminal tear machine open or be connected on beta version by fly line, wherein intelligent terminal comprises panel computer, smart mobile phone, intelligent televisions etc. are with intelligent digital product and the intelligent appliance product of USBID pin.
