Background technology
Along with the continuous maturation of machine vision technique, the application of machine vision technique is more and more extensive.Often can use the industrial camera of USB interface in the application of adopting machine vision technique; in the process of using the USB interface industrial camera; if in advance camera is connected to the USB interface of host computer; by situation about often can identify less than camera, so just need manual plug camera so that host computer can be identified at os starting.In addition, connect in the control system of a plurality of USB interface industrial cameras at needs, system can not be automatically corresponding with the connected USB interface of camera sequence number, need to manually arrange separately.
The utility model content
The purpose of this utility model is in the application of adopting machine vision technique, sometimes None-identified USB interface industrial camera and can't be automatically that the camera sequence number is corresponding with USB interface problem after system starts, provide a kind of SCM Based USB interface industrial camera automatically to go up controller for electric consumption, can control separately each the USB interface industrial camera power supply that connects, and can identify the camera sequence number that each USB interface connects, improve the reliability that the USB interface industrial camera is used at machine vision technique, and increased substantially Installation and Debugging efficient.
The technical scheme that its technical matters that solves the utility model adopts is:
a kind of SCM Based USB interface industrial camera is gone up controller for electric consumption automatically, include host computer, a plurality of industrial cameras, it is characterized in that: also include single-chip microcomputer, power supply control chip, USB socket, USB turns serial port chip, four IO mouths of described single-chip microcomputer power supply of a power supply control chip of control linkage are respectively controlled pin, the input pin of four power supply control chips, output pin is connected with the Vcc end of a USB socket respectively, the USB socket of the USB socket that is connected with the input pin of power supply control chip is connected with host computer, the USB socket of the USB socket that is connected with the output pin of power supply control chip is connected with an industrial camera respectively, host computer turns serial port chip by a USB socket with USB and is connected, the other end that USB turns serial port chip is connected with the serial ports of single-chip microcomputer.
The model that described USB turns serial port chip is FT232.The signal of power supply control chip is LTC4413.
Four power supplys that the utility model is controlled power supply chip with four IO mouths of single-chip microcomputer are controlled pin, and single-chip microcomputer communicates by serial ports and host computer.Host computer electrifying startup initialization camera programm powers on by realizing controlling different industrial cameras to single-chip microcomputer transmission different instruction, identifies one by one sequence number and the camera title of the camera that powers on.
The beneficial effects of the utility model are:
The utility model has solved the problems such as the frequent plug of USB interface and industrial camera None-identified, increases substantially the efficient of USB industrial camera in machine vision technique is used.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is theory diagram of the present utility model.

Fig. 3 is PC control process flow diagram of the present utility model.
Embodiment
in Fig. 1, a kind of SCM Based USB interface industrial camera is gone up controller for electric consumption automatically, include host computer 1, a plurality of industrial cameras 2, single-chip microcomputer 3, power supply control chip 4, USB socket A1-A5 and B1-B4, USB turns serial port chip 5, four IO mouths of single-chip microcomputer 3 power supply of a power supply control chip 4 of control linkage are respectively controlled pin, the input pin of four power supply control chips 4, output pin is connected with the Vcc end of a USB socket respectively, the USB socket of the USB socket A1-A4 that is connected with the input pin of power supply control chip 4 is connected with host computer 1, the USB socket of the USB socket B1-B4 that is connected with the output pin of power supply control chip 4 is connected with an industrial camera 2 respectively, host computer 1 turns serial port chip 5 by a USB socket A5 and USB and is connected, the other end that USB turns serial port chip 5 is connected with the serial ports of single-chip microcomputer 3.
The model that USB turns serial port chip 5 is FT232.The signal of power supply control chip 4 is LTC4413.
Single-chip microcomputer 3 turns serial port chip 5 by USB and is connected with the USB interface of host computer, and host computer 1 is controlled corresponding camera by sending controling instruction and powered on, cuts off the power supply.4 I/O mouths of single-chip microcomputer 3 use are controlled respectively the enable pin of power supply control chip 4, and the instruction that sends according to host computer 1 realizes that industrial camera 2 powers on separately and cuts off the power supply.During on-the-spot the use, the industrial camera of USB interface is connected to USB socket B1 of the present utility model～B4, by USB cable, USB socket A1 of the present utility model～A5 is connected to host computer, can connect at most the industrial camera of four USB interface.
In Fig. 2, the program control flow chart of single-chip microcomputer has been described.At first the register such as serial ports and variable are carried out initialization after single-chip microcomputer powers on, then circular wait receives the PC control instruction.When receiving camera and power on order, control specified camera according to command context and power on.When receiving the camera power off command, control the specified camera outage according to command content.
In Fig. 3, the program control flow chart of host computer has been described.After system started, at first host computer sent camera 1 instruction that powers on, and then starts a timer, and inquiry identification camera in timer interrupts is if find camera the sequence number and the camera title that read and preserve camera.If do not find camera in timer interrupts, send camera 1 cut-offing instruction, then resend power on instruction and opening timing device of camera 1 and interrupt, again identify camera.If all do not find camera after identifying 5 times show camera 1 fault, system stops detecting other camera.After recognizing camera 1, then send in order camera 2,3,4 instruction that powers on, if system recognizes respectively 2,3,4 cameras, reading and saving camera sequence number and title respectively, complete the camera power up.In identification camera 2,3,4 process, if find that certain camera None-identified is just in host computer demonstration respective camera fault.
