Embodiment
Be elaborated below in conjunction with the embodiment of accompanying drawing to embodiment of the present invention.
See also shown in Figure 1; System architecture diagram for the download system of the portable terminal of embodiment of the present invention; The download system of this portable terminal comprises industrial control computer 10, power-supply unit 12 and download website 13, and wherein industrial control computer 10 all is connected with download website 13 with power-supply unit 12, and wherein industrial control computer 10 is host computers; Accomplish the control of signal; And export usb signal (comprising D+/D-/Gnd) and give download website 13, and power-supply unit 12 provides download website 13 power supplys, this download website 13 is connected with portable terminal 2.
The design of mobile terminal downloads system has two kinds of modes usually; A kind of is the download system that makes up (portable terminal when promptly being equivalent to not load onto shell) to the mobile terminal circuit plate; Another kind is the download system to the portable terminal complete machine, below explains respectively.
For download system to the combination of mobile terminal circuit plate; In the specific implementation, for promoting speed of download and the operation of being convenient to production line, need set up the D+/D-test point in the design of mobile terminal circuit plate; Considered by its stability factor; This measuring point must be lacked and near the USB interface on the mobile terminal circuit plate as far as possible, and the cabling aspect must difference, and isometric equidistance is done bag ground and handled; The filter capacitor and the filtering magnetic bead of power pack circuit that connects the USB pin of baseband chip of mobile terminal simultaneously all can not be cancelled, and portable terminal must be through the test of USB eye pattern in addition.When implementing, usb signal is connected on the D+/D-test point after being directed to industrial control computer 10, and it downloads stable because the communication harmful effect appears in the decay that middle switching or routing problem cause signal to avoid usb signal at a high speed.In the specific implementation; Facility for operation; Can be connected on the D+/D-test point of mobile terminal circuit plate through a probe (not shown); The other end of probe then is connected with the usb signal output port of download website 13, and this moment, the mobile terminal circuit plate also was connected with the power input mouth of download website 13, thereby by download website 13 working power of mobile terminal circuit plate is provided.
For promoting output and maximum using hardware resource; Multichannel download website is designed to the form of 1 holder 12; Be that download website has 3 sub-download units; Each sub-download unit has 4 download channel, so can let 12 mobile terminal circuit plate combinations download simultaneously, and the structure of sub-download unit is as shown in Figure 2.Common sub-download unit comprises control module, USB module, direct current 5V module and protection module; The USB module directly is connected with the USB mouth 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 the DB25PIN connector, and this connector is in order to transmission power control signal, downloading mode control signal, anchor clamps feedback signal, starting-up signal, usb signal etc.; And each DB25PIN connector also correspondence disposes 3 pilot lamp; In the specific implementation, can be provided with red, yellow, green three LED lights, wherein red led is represented failed download; Yellow indication is downloaded, and green LED is represented to download successfully.
Download system for the portable terminal complete machine; Can adopt sub-download unit structure as shown in Figure 3; Each sub-download unit has 6 download channel, can support 6 portable terminals to download simultaneously, and download website is typically provided with two sub-download units so that 12 portable terminals can be downloaded simultaneously.In the download system of portable terminal complete machine, adopt a kind of USB cable to be connected between download channel and the portable terminal, specifically as shown in Figure 4, wherein an 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 micro USB connector 32; In order to be connected with the micro USB interface (not shown) of portable terminal; And also be provided with the 3rd connector 33 in the middle of this USB cable, in order to be connected, so that the portable terminal power supply to be provided with the output port of power source of sub-download unit; Be that portable terminal is the output port of power source power supply through sub-download unit, rather than through the USB confession.
The download system that no matter makes up for the mobile terminal circuit plate still is the download system of portable terminal complete machine, aspect control, can introduce the multithreading control technology.The multithreading control technology is meant and comprises a plurality of execution streams in the program, promptly in a program, can move a plurality of different threads simultaneously and carry out various tasks, that is to say to allow the thread of a plurality of executed in parallel of single program creation to accomplish task separately.The great advantage of multithreading control is exactly to improve the utilization factor of central processing unit greatly.。In multithread programs, when a thread must be waited for, central processing unit can move other thread rather than wait, realized that many portable terminals download maximized raising production capacity simultaneously.Perhaps for letting the more time taking operation in backstage, can start a thread and go to carry out this operation, program continues to carry out simultaneously, thereby raises the efficiency.
For promoting the stability of downloading; Can adopt more stable programmable power supply for the power supply and the communication of portable terminal on the one hand; On the other hand because be provided with overvoltage and current foldback circuit in the download website; Guaranteeing at 12 portable terminals simultaneously in the process of downloading, wherein any one is short-circuited badly, can influence neighboring terminals and download.
It is understandable that, concerning those of ordinary skills, can be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, and all these changes or replacement all should belong to the protection domain of the appended claim of the present invention.
