Description
SYSTEM FOR AUTOMATIC CONFIGURATION OF A CONTROL KEYBOARD OF AN OPTOELECTRONIC SENSOR
TECHNICAL FIELD
The present invention relates to a system for automatic configuration of a control keyboard of an optoelectronic sensor.
More specifically, the present invention relates to a system for automatic configuration of a control keyboard of an optoelectronic sensor corresponding to a vision sensor, to which the following description refers purely by way of example.
BACKGROUND ART As is known, vision sensors are optoelectronic devices for acquiring and processing the image of an object to determine conformance or not of the object with predetermined characteristics and accordingly supply information concerning, for example, the quality and integrity of the object, or the presence/absence of a specific component or a graphic element in the object, etc.
Some last-generation vision sensors have an
interface device comprising a control keyboard that allows the operator to impart commands to the vision sensor; and a display for displaying operator-imparted commands or other useful information. More specifically, the control keyboard allows the operator to select and impart commands to the vision sensor from a list or specific predetermined menu stored in a memory of the vision sensor.
As is known, to operate, vision sensors must first be programmed, which comprises configuring an inspection method containing the control operations to be performed by the sensor when inspecting the objects; and assigning specific predetermined values to inspection parameters characteristic of the selected inspection method. Being complicated to define, initial programming of the inspection method and relative configuration parameters is normally performed by the operator using a processing device separate from the vision sensor and interfaced to it by a communication system. More specifically, the processing device is normally a personal computer, which implements an inspection configuration program that allows the operator to construct the inspection method to be implemented by the sensor when inspecting the objects. In the case in question, the configuration program allows the operator to select one or more inspection modes relative to the inspection method controls, and to assign values to the inspection parameters characteristic of the inspection
modes .
Once programmed, the vision sensor inspects the objects in accordance with the inspection method configured by the operator, but any changes by the operator to the inspection modes or relative inspection parameters, to refine inspection or make inspection changes, can only be made using the personal computer inspection configuration program.
In fact, the control menu operations performable on the control keyboard only allow the operator a very limited amount of freedom in adjusting certain image acquisition calibration parameters (e.g. exposure time, brightness level) , but do not permit adjustments to the inspection parameters characteristic of the inspection method being implemented, as required to refine or make changes to the inspection method initially programmed on the personal computer.
On the other hand, whereas the control keyboard does not permit changes to the inspection parameters defining the inspection mode programmed by the personal computer, it is subject to accidental commands generated by accidental operation of the keys. That is, during implementation of the inspection method by the vision sensor - hereinafter referred to as the "sensing condition" - the operator may inadvertently press one or more keys on the keyboard, thus imparting one or more random commands to the vision sensor, with obvious repercussions on object inspection by the sensor.
DISCLOSURE OF INVENTION
It is therefore an object of the present invention to provide a system for automatically configuring the control keyboard of an optoelectronic sensor,
5 corresponding in particular to a vision sensor, on the basis of inspection parameters programmed in the predetermined inspection mode, so that, to refine inspection of the objects, inspection parameter values may be adjusted by the operator directly from the
10 keyboard, without recourse to the personal computer inspection configuration program.
It is a further object of the present invention to provide a system designed to automatically disable operation of a control keyboard of an optoelectronic 15 sensor, so as to disable, during object inspection, any accidental command generated by inadvertently pressing the keys on the control keyboard.
According to the present invention, there is provided an optoelectronic sensor as claimed in Claim 1 20 and preferably in any one of the following Claims depending directly or indirectly on Claim 1.
According to the present invention, there is also provided a system for automatic configuration of a control keyboard of an optoelectronic sensor, as claimed
" 25 in Claim 7. δ
According to the present invention, there is also provided an optoelectronic sensor as claimed in Claim 8 and preferably in any one of the following Claims
depending directly or indirectly on Claim 8.

BEST MODE FOR CARRYING OUT THE INVENTION
Number 1 in Figure 1 indicates as a whole a system for automatically configuring commands impartable from a control keyboard 2 integrated in an optoelectronic sensor .
In the example shown, the optoelectronic sensor is a vision sensor 3, which, implementing a predetermined inspection method, provides for acquiring and processing
the image of at least one object, to determine conformance or not of the object with specific characteristics in the inspection method, and to accordingly supply information relative to the presence/absence of a given match between the acquired object and a specimen reference object.
In addition to the optoelectronic sensor corresponding to vision sensor 3, system 1 also comprises a processing unit 4 defined, for example, by a known personal computer, which comprises a monitor 5, a keyboard 6, and a memory 7, and is interfaced to vision sensor 3 by a known communication system 8 (not described in detail) to permit data exchange between the two. The personal computer, also indicated 4, implements an inspection configuration program 9 of vision sensor 3 (shown schematically by a dash-line block in Figure 1) that allows the operator to define the inspection, i.e. control, method to be implemented on the object/s by vision sensor 3. More specifically, inspection configuration program
9 comprises displaying on monitor 5 a graphic interface
10 that allows the operator to configure the inspection to be performed on the objects by vision sensor 3. In the example shown, the operator, using control keyboard 6, may select the inspection mode/s to be implemented in the inspection method from a list of predetermined inspection modes stored in memory 7, and may assign a given value to each of the inspection parameters characteristic of the
selected inspection mode/s.
More specifically, the inspection method may- comprise one or more inspection modes. For example : a first inspection mode containing a set of operations which process the image to determine the resemblance between an acquired object and the reference object; a second inspection mode comprising a number of operations for determining the presence or not, in the acquired image, of a predetermined number of objects or components (e.g. for determining or counting the number of tablets in a blister pack) ; and a third inspection mode comprising a number of operations for determining whether the outline of a given object matches that of the reference object. The inspection method inspection parameters may- comprise, for example : the positions the inspected object should assume in the image with respect to a cartesian reference system; inspection time precision; the degree of similarity or similarity threshold of the inspected and reference objects; inclination of the object in the image with respect to the reference system; the width of the object in the image; the internal area and/or perimeter of the object/s sought in the image; the colour and/or shade of the inspected object/s ; the distance between a reference outline and the outline of the acquired object, etc.
Vision sensor 3 substantially comprises an image acquisition device 11 defined, for example, by a
television or still camera; and a processing module 12 defined, for example, by a microprocessor or any similar electronic circuit, for processing the images acquired according to the configured inspection method, i.e. as a function of the inspection mode/s configured by processing unit 4, and of the values assigned to the relative inspection parameters.
Vision sensor 3 also comprises a memory device 13 for memorizing a predetermined command menu 14 (shown schematically in Figure 1) comprising a list of commands that can be imparted to vision sensor 3; and an interface device, in turn comprising control keyboard 2, by which the operator imparts the commands in predetermined command menu 14 to processing module 12, and preferably, though not necessarily, a display 16 showing the commands imparted from control keyboard 2.
Once the inspection method is configured by the operator on personal computer 4, vision sensor 3 receives the configured inspection method data and the relative inspection parameters with the respective assigned values .
At this point, processing module 12 reconfigures, i.e. modifies, the command menu 14 in memory device 13 as a function of the received inspection parameters, to allow the operator to modify, from control keyboard 2, the value of each inspection parameter during operation of vision sensor 3.
More specifically, processing module 12 modifies
command menu 14 on the basis of the inspection method configured previously on personal computer 4, and adds to the initial commands in the predetermined version of command menu 14 (a portion of which is shown by way of example in Figure 2) a number of additional commands (a portion of which is shown by way of example by block 14a in Figure 3) , each of which allows selection and change of an inspection parameter in the configured inspection method, so that the operator can modify the value assigned to the inspection parameter and refine inspection by vision sensor 3 from control keyboard 2, with no recourse to personal computer 4 or any other additional processing device. In the Figure 3 example, processing module 12 has reconfigured the command menu predetermined on the basis of the received inspection parameters (Figure 2) by adding a number of additional commands (14a) , which provide, for example, for commanding selection of the added inspection parameters, and, once an inspection parameter is selected, e.g. the i-th parameter, for increasing or reducing the value of the selected inspection parameter.
The above method of automatically configuring control keyboard 2 also comprises a procedure for automatically disabling control keyboard 2, and which provides for disabling commands impartable to processing module 12 from control keyboard 2.
More specifically, Figure 4 shows operation of vision sensor 3 to automatically disable the commands
impartable to vision sensor 3. Firstly, processing module 12 of vision sensor 3 determines operation of one or more keys on control keyboard 2 (block 100) and whether vision sensor 3 is in an object inspection condition (block 110) . In the example shown, at this point, processing module 12 determines whether the vision sensor is performing the operations in the object inspection method.
If it is not (NO output of block 110), i.e. if vision sensor 3 is in a rest condition or parameter configuration condition, in which no object inspection is performed, it switches to a standby condition pending further operation of the keys on control keyboard 2. Conversely (YES output of block 110), i.e. if vision sensor 3 is in the sensing, i.e. object inspection, condition (performing the inspection operations in the inspection method) , processing module 12 begins measuring the time interval T (block 120) since the keys on control keyboard 2 were last operated. In the example shown, processing module 12 determines whether the time interval T, in which no keys have been pressed on control keyboard 2, satisfies a given relationship with a time threshold Sτ (block 130) .
If the given relationship is satisfied (YES output of block 130) , processing module 12 disables control keyboard 2 (block 140) . In the example shown, when the time interval T, in which none of the keys on control keyboard 2 have been operated, substantially equals the
given time threshold Sτ, processing module 12 commands a "control keyboard 2 lock", in which any communication between the commands generated on control keyboard 2 and processing module 12 is cut off, to prevent the commands being implemented by processing module 12.
Control keyboard 2 may be reactivated by a number of predetermined operations, such as pressing a given key for a given length of time, or simultaneously pressing a combination of keys on control keyboard 2. In connection with the above, it should be pointed out that the automatic keyboard disabling procedure described applies to any type of optoelectronic sensor, even differing from the vision sensor described. More specifically, the procedure may also be applied to light- emitting optoelectronic sensors using LEDs or LASER beams, for measuring the distance (e.g. by calculating light pulse flight time) , colour and shape of objects, and for determining the presence of predetermined elements in objects. The advantages of system 1 as described herein are obvious: the operator is able to modify the inspection parameters of, and so refine, the current inspection method quickly and intuitively from control keyboard 2, with no need to reconfigure vision sensor 3 on the personal computer or any other additional processing unit 4.
Moreover, automatically disabling control keyboard 2, after a given time lapse since the last command
imparted from the keyboard, safeguards against anomalous operation of the vision sensor caused by accidental commands entered as a result of inadvertent operation of the keys on the keyboard.
Clearly, changes may be made to system 1 as described and illustrated herein without, however, departing from the scope of the present invention as defined in the accompanying Claims.
