This utility model detailed description of the invention is as follows:
As shown in Figures 1 to 3, the design mainly includes primary module, input/output module and can the camera control of multiple cascades
Module.Wherein module based on primary module, connects including power module, MCU able to programme, analog and digital signal module and communication bus
Mouthful.Power module is powered for power supply and some outside associate devices of all modules of native system；MCU able to programme is used for inputting
The current state of tested object and peripheral device communication and to peripheral equipment control in the detection process of signal, visual system
The output of signal；Analog and digital signal end can receive external environment condition analogue signal and digital signal, provides for vision detection system
External device status and environmental information, wherein reserved multiple signaling interfaces, can access encoder, sensor, light source etc. normal
The vision-based detection corollary equipment of rule.For encoder, photoelectric sensor, metal sensor isopulse signal device, its work electricity
Pressure and MCU pressure reduction are relatively big, at same operating at voltages, therefore the circuit through the composition such as optocoupler or transistor can not be needed to carry out electricity
(encoder belongs to optional device in kinetic control system to pressure conversion just accessible MCU herein.Increase encoder can get
More system motion information, and whole system control accuracy can be improved).For analog device, if running voltage and MCU exist
Same scope, then can be directly connected to simulate input interface accordingly；If not in same scope, then need by ability after external conversion
Accessible.For MCU, pulse signal is considered digital signal, will think by continually varying signal in particular range
It it is analogue signal.
Input/output module extended method uses following several: parallel-expansion can use TTL, cmos circuit latch or three
State door realizes, such as: 74LS244,74LS273.I/O port can simulate the interfaces such as I2C, SPI, can realize minority I/O port and control many
Individual device.I/O extension uses decoder, such as 74LS138.
Input/output module uses modbus bus communication protocol, it is achieved the information of external equipment and motion controller is handed over
Mutually, and according to Content of Communication Correlation method for data processing and input and output relevant control are carried out.
Camera control module is to connect camera and the middleware of MCU, and its functional realiey is mainly made up of two parts, software journey
Sequence regulation and control and hardware circuit flow-dividing control, can produce line demand according to reality and carry out cascade extension.Software program regulation and control part is main
Produce the triggering signal that camera image gathers.And hardware circuit flow-dividing control part realizes multichannel by multiplexer circuit and passes
Defeated channel selecting, realizes the mutually isolated of each camera control signal with this and uses simultaneously.
Hardware shunt controls there are two kinds of implementations: first kind of way, is realized by 74HC4066 logical device in Fig. 1.
MCU output signal CTL1,74HC4066 realizes the switching of internal switching circuits according to CTL1 signal, such as: when CTL1 signal is high
During level, the input of 74,HC4,066 13 pin is high level, and now internal switch 1 is opened, 74HC4066 the 1st pin and the 2nd pin
Conducting, i.e. the signal CH1_IN of MCU output can export with CH1_OUT signal from pin 2.In like manner, for multiple signals output control
System, it is only necessary to can realize by first via circuit connecting mode.The second way, can by multichannel reserved on pcb board in Fig. 2
Selecting resistance to carry out path selection, i.e. for the circuit board of identical PCB difference numbering, the most only welding is corresponding with this numbering
Resistance.As shown in FIG., if this PCB is " output signal " for camera control signal, the signal that the output of MCU end can use has " letter
Number 1-3 ", then can optionally be welded by R1-R4 in figure, the signal behavior of different cameral can be realized, MCU module sends camera
Controlling signal to camera control module, each camera control module is reserved two identical camera control signals of output signal and is connect
Mouthful, to realize the parallel connection of multiple camera control module.I.e. MCU module is connected to camera control module 1, and camera control module 2 is even
Being connected in camera control module 1 on another interface of reserving, by that analogy, rear class camera model is connected to previous phase
In machine control module.Above-mentioned shunting mode is applicable to area array cameras and line-scan digital camera.
Synchronized movement of the present utility model realizes principle: encoder inputs defeated with sensor signal by analog and digital signal
Go out port by through isolation after signal be sent to MCU, MCU calculate product image acquisition according to sensor and code device signal time
Between put and send triggering signal to camera control module, camera control module controls camera and adopts figure, and above description object is separate unit
Testing machine system.
In multiple stage testing machine system, there is the cascade situation of multiple camera control module.Every camera in utility model
It is equipped with one piece of camera control module, and cascades up between each camera control module.In system is run, MCU is according to being
System runs relevant information, can produce camera control signal to camera control module in the suitable moment.Camera control module passes through
Multiple signals control circuit can control camera after being changed by this signal and carry out image acquisition.So pass through software and hardware
The mode combined, just completes multiple stage testing machine system coordination and controls.
As it is shown on figure 3, this utility model modularity can Distributed Motion Control System as follows: by power module, master control mould
Block (i.e. MCU module), input/output module, camera control module, and system use encoder, sensor etc. is according to system
Operation instruction is progressively installed according to onsite application situation, after installation, coherent signal line is connected and check errorless after
Power-on switchs.Open PC end system debugging software simultaneously, the correlation module of motion controller system is tested and (includes
Common input, output, communication, camera control, warning etc.).After more than having tested, plant produced line, MCU mould can be opened
Tuber calculates the current running status producing line product according to the external signal (encoder, sensor) received, and by result of calculation
It is sent to PC by EBI, and in the corresponding moment by sending camera control signal to camera control module (MCU module
Can use or cascade use according to reality application is independent to the transmission of camera control module).Camera control unit is to receiving
Camera is changed and delivered to signal accordingly, triggers camera and carries out image capturing.
Although the foregoing describing detailed description of the invention of the present utility model, but those familiar with the art should
Working as understanding, our described specific embodiment is merely exemplary rather than for the limit to scope of the present utility model
Fixed, those of ordinary skill in the art, in the equivalent modification made according to spirit of the present utility model and change, should
Contain in scope of the claimed protection of the present utility model.
