Embodiment
Below in conjunction with accompanying drawing, enforcement the specific embodiment of the present invention is described in detail.
Refer to shown in Fig. 1, for implementing the system architecture diagram of the download system of mobile terminal of the present invention, the download system of this mobile terminal comprises industrial control computer 10, power-supply unit 12 and download website 13, wherein industrial control computer 10 is all connected with download website 13 with power-supply unit 12, wherein industrial control computer 10 is host computers, the control of settling signal, and export usb signal (comprising D+/D-/Gnd) to download website 13, and power-supply unit 12 provides download website 13 power supply, this download website 13 is connected with mobile terminal 2.
The design of download system of mobile terminal has two kinds of modes usually, one is the download system for mobile terminal circuit plate combination (being namely equivalent to mobile terminal when being unkitted upper shell), another kind is the download system for mobile terminal complete machine, is explained respectively below.
For the download system combined for mobile terminal circuit plate, in the specific implementation, for promoting speed of download and the operation being convenient to production line, need in the design of mobile terminal circuit plate to set up D+/D-test point, consider by its stability factor, this measuring point must be tried one's best short and USB interface on the mobile terminal circuit plate, and cabling aspect must difference, isometricly processes with equidistantly wrapping; The filter capacitor and the filtering magnetic bead that connect the power pack circuit of the USB pin of baseband chip of mobile terminal all can not be cancelled simultaneously, and mobile terminal must be tested by USB eye pattern in addition.When implementing, usb signal is connected in D+/D-test point after being directed to industrial control computer 10, and it downloads stability to avoid usb signal at a high speed to occur communication harmful effect because the switching of centre or routing problem cause the decay of signal.In the specific implementation, for the facility of operation, be connected in the D+/D-test point of mobile terminal circuit plate by a probe (not shown), the other end of probe is then connected with the usb signal output port of download website 13, and now mobile terminal circuit plate is also connected with the power input port of download website 13, thus provide the working power of mobile terminal circuit plate by download website 13.
For improving yield and maximum using hardware resource, multichannel download website is designed to the form of 1 holder 12, namely there are 3 sub-download units in download website, each sub-download unit has 4 download channel, 12 mobile terminal circuit plate combinations so can be allowed to download, and the structure of sub-download unit as shown in Figure 2 simultaneously.Usual sub-download unit comprises control module, USB module, direct current 5V module and protection module; USB module is directly connected with the USB port of industrial control computer 10; direct current 5V module is connected with power-supply unit 12, and protection module is an overvoltage and current foldback circuit.
In the specific implementation, download channel is DB25PIN connector, this connector is in order to transmit power control signal, downloading mode control signal, fixture feedback signal, starting-up signal, usb signal etc., and each DB25PIN connector also correspondence is configured with 3 pilot lamp, in the specific implementation, can be provided with red, yellow, and green three LED light, wherein red led represents failed download, yellow instruction is downloaded, and green LED represents and downloads successfully.
For the download system of mobile terminal complete machine, sub-download unit structure as shown in Figure 3 can be adopted, each sub-download unit has 6 download channel, and can support that 6 mobile terminals are downloaded simultaneously, download website is typically provided with two sub-download units so that 12 mobile terminals can be downloaded simultaneously.In the download system of mobile terminal complete machine, adopt a kind of USB cable to be connected between download channel with mobile terminal, specifically as shown in Figure 4, wherein one end of this USB cable is provided with one first USB connector 31, in order to be connected with the USB interface of download channel; And the other end is provided with the second Minimized USB connector 32, in order to be connected with the minitype USB interface (not shown) of mobile terminal, and be also provided with the 3rd connector 33 in the middle of this USB cable, in order to be connected with the output port of power source of sub-download unit, to provide mobile terminal power supply, namely mobile terminal is powered by the output port of power source of sub-download unit, instead of powered by USB port.
No matter for download system or the download system of mobile terminal complete machine of the combination of mobile terminal circuit plate, in control, Multi-thread control technology can be introduced.Multi-thread control technology refers in program to comprise and multiplely performs stream, namely can run multiple different thread to perform different tasks in a program simultaneously, that is allow the thread of the multiple executed in parallel of single program creation to complete respective task.The great advantage of Multi-thread control is exactly to improve the utilization factor of central processing unit greatly.。In multithread programs, when a thread must be waited for time, central processing unit can run other thread instead of wait, realizes multiple stage mobile terminal and downloads simultaneously, maximized raising production capacity.Or for allowing the more time taking operation in backstage, can start a thread and going to perform this operation, program continues to perform, thus raises the efficiency simultaneously.
For promoting the stability downloaded; on the one hand can adopt more stable programmable power supply for the power supply of mobile terminal and communication; on the other hand because be provided with overvoltage and current foldback circuit in download website; to guarantee in the process downloaded at 12 mobile terminals simultaneously; wherein any one is short-circuited bad, all can not affect adjacent terminal downloads.
Be understandable that, for those of ordinary skills, can be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, and all these change or replace the protection domain that all should belong to the claim appended by the present invention.
