Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for restricting operation of a measuring machine such as a coordinate measuring machine, an image shape measuring machine, and a contour shape measuring machine.
[0002]
[Prior art]
In recent years, measuring machines, such as a three-dimensional measuring machine and an image measuring machine, have been incorporated in a production line of a factory in-line. Along with this, there has been an increasing number of cases in which a manufacturing technician operates a three-dimensional measuring machine that has been operated only by a measurement technician. For this reason, in the measurement operation using an in-line type three-dimensional measuring machine, automatic measurement is often performed by a part program so as not to require much skill.
[0003]
However, if the operator erroneously inputs an editing command for the part program by some operation, the part program itself is easily changed, and the subsequent measures are not understood, and careless damage to the probe or the like may occur. Will cause problems. Overseas, where work sharing at the site is clear, taking into account such situations, ISO9000, QS9000, etc., demanded that anyone cannot operate the contents of the part program, which is the core of measurement, without permission. I have. Also, with the standardization of the part program description language being advanced, if the part program is taken out freely outside the company, the part program can easily grasp the dimensions and tolerances of the product parts, leading to the loss of know-how. There is also a risk.
[0004]
In order to solve such a problem, there has been proposed a method of limiting the operation and functions of the measuring instrument. For example, in the method for restricting operation of a measuring instrument disclosed in Japanese Patent Application Laid-Open No. 2000-67002, as shown in FIG. 7, the executable operations / functions (functions 1 to 5) of the measuring instrument have respective levels (L1 to L5). ) Is set, and the password of the operator who operates the measuring instrument and the operation levels (L1 to L5) are associated and registered in advance. Then, the user is prompted to input a password so that operations other than operations and functions of the operation level corresponding to the password cannot be executed. For example, when the function 4 is set to the operation level L4, an operator whose operation level is lower than L3 cannot use the function 4, and only the functions 3 and 5 can be used.
[0005]
[Problems to be solved by the invention]
However, each operator has some advantages and disadvantages in the operation of the measuring instrument, and even an operation that is generally difficult may be an easy operation for a person who has received sufficient training on the operation. . For example, the editing function of a part program is a function of a high level of difficulty corresponding to level 4 for a general operator, but is a function of a low level of difficulty corresponding to level 2 for an operator who has been specially trained in editing a part program. It is a function.
[0006]
In such a case, a conventional method in which a level is fixedly set for each function and the level is assigned to each operator cannot set an optimal operation limit for each operator. For example, even when the result of the training for measuring instrument operation is obtained or the experience of a specific operation is accumulated and the proficiency is increased, the operation restriction setting cannot be sequentially canceled. As a result, the operator's skill level of operation and the result of function proficiency cannot be fully drawn out, which may hinder highly reliable measurement and may hinder utilization of human resources. There was also.
The present invention has been made in order to solve these problems, and there is provided a measuring instrument or a method for restricting the operation of a measuring instrument which enables a function restriction flexibly corresponding to an improvement in proficiency of each operator. The purpose is to provide.
[0007]
[Means for Solving the Problems]
To achieve the above object, a measuring device according to the first invention of the present application is a measuring device that selectively allows an operator to operate a predetermined operation function item. A registration unit for registering operation permission or non-permission of the operation function item for each confirmed operator confirmed by the unit, and selectively permitting the operation of the confirmed operator according to the permitted operation function item And a permission unit for performing the operation.
[0008]
According to the first aspect, when the confirmation unit confirms the operator by collation of the password input by the operator or fingerprint collation, the operation unit permits the operation of the operation function item registered for each confirmed operator in the registration unit. The non-permission information is read out, and based on this information, the permission unit determines whether the individual operation of the confirmed operator is a permitted operation, and restricts the operation of the operation function item that is not permitted. Therefore, the operation functions that can be executed can be selectively and finely set according to the unique experience and proficiency of each operator, so that optimum operation restrictions can be added to each of the operators from beginners to experienced operators, and work and measurement equipment associated with erroneous operations can be set. Can be prevented beforehand.
Here, the operation function refers to various operations and functions of the measuring device, such as input of various commands and instructions for operating the measuring device, or creation and editing of a part program. The operation restriction refers to making the function to be restricted unselectable, ignoring an input command or command, or outputting or displaying a warning to avoid execution.
[0009]
In the first aspect, it is preferable that the operation function item further includes a permission condition, and that the operation permission or non-permission of the operation function item is updated according to a state of satisfaction of the permission condition. is there. As a result, for each of the various operation function items, the operation permission or non-permission is updated according to the state of satisfaction of the set permission condition, so that the operation restriction can be appropriately released or strengthened.
In this case, the registration unit further includes a timing unit that counts the operation time of the measuring device for each of the confirmed operators to obtain an integrated time, and the permission condition is a predetermined time set for each of the operation function items. It is preferable that when the accumulated time exceeds the predetermined time, the corresponding operation function item is updated to operation permission. As a result, the information of permission / non-permission of each operation function item can be updated according to the accumulated time of the operation of the influential measuring instrument as a measure of the skill level. In addition, maintenance of unauthorized information becomes easy.
[0010]
The registration unit may further include a question unit provided for each of the operation function items, wherein the permission condition is a proper answer, and the confirmed operator makes the proper answer to the question of the question unit. In this case, it is preferable to update the operation function item that corresponds to the operation permission, or update the operation function item that corresponds to the case where the appropriateness is not answered, to operation not permitted.
According to the present invention, when a function that cannot be permitted by merely learning, such as reference to the contents of a part program, requires confirmation of confidentiality and approval of confidentiality obligation, a predetermined confidentiality test or The operator is inquired about whether or not to make a confidentiality oath, and the permission and non-permission of the operation function items can be updated according to the contents of the answer, so the permission and non-permission information of the operation function managed for each operator is maintained at a higher level It is easier to do.
[0011]
To achieve the above object, a method for restricting the operation of a group of measuring instruments according to the second invention of the present application is a method for limiting one or more measuring instruments of the same type that selectively allows an operator to operate a predetermined operation function item. In the group operation restriction method, a recognition step of confirming the operator and recognizing a confirmed operator; a registration step of registering operation permission or non-permission of the operation function item for each confirmed operator; According to the present invention, the method further comprises a specifying step of specifying the operation function item of the confirmed operator according to the operation function item, and a restriction step of restricting the operation of the specified operation function item. According to the present invention, the operation of the operation function items can be restricted by the same procedure even for a plurality of the same type of measurement devices such as a three-dimensional measurement device having only a different measurement range. The management of the permission information is facilitated, and the operator is also restricted from operating in the same state for a plurality of the same type of measuring instruments, so that mistakes in the operation can be prevented.
[0012]
In the second aspect, it is preferable that the registration step further includes an update step of updating operation permission or non-permission of the operation function item in accordance with a state of satisfaction of a predetermined permission condition.
In addition, it is preferable that the satisfaction condition of the permission condition is determined based on the satisfaction condition of each of one or a plurality of measuring instruments of the same type. According to the present invention, for example, when the proficiency level is determined in a predetermined time set for each operation function item as the permission condition, the individual operation integration times when each of the CMMs having different measurement ranges are operated are totaled. Since the satisfaction state determination as to whether or not the permission condition is satisfied is performed, more appropriate proficiency level determination can be performed.
[0013]
Further, the information of the operation permission or non-permission of the operation function item registered in the registration step is stored in a host computer or one of a plurality of measuring instruments of the same type or a portable medium. It is preferable to use it on a stand or a plurality of measuring instruments of the same type. As a result, since information on permission or non-permission of operation of the operation function item is centrally managed, there is no inconsistency in the contents as compared with the case where the information is registered for each individual measuring device, and the management is easy. . Here, information exchange between the host computer or one or a plurality of similar measuring instruments may be performed via a portable medium such as a floppy disk, but is preferably interconnected by a network. In addition, the information of the operation permission or non-permission of the operation function items and the accumulated time are stored in a portable medium such as a floppy disk or an IC card, and are carried by individual operators to start the operation of the measuring instrument. May be read into the registration unit of the measuring instrument, and upon completion of the operation, the contents of the registration unit may be stored again in these portable media.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a three-dimensional measurement system according to an embodiment of the present invention. The system includes a coordinate measuring machine 1 that outputs its three-dimensional coordinate value by contact of a measuring probe, a controller 2 for driving and controlling a measuring probe of the coordinate measuring machine 1 in a three-dimensional space, and a controller 2 And a computer 3 for supplying a measurement command to the computer 2. The computer 3 includes a part program storage unit 11 therein, selects one of the part programs stored in the part program storage unit 11, executes the selected part program in the measurement processing unit 12, and transmits a necessary measurement command. The data is output to the controller 2 and the measured data from the coordinate measuring machine 1 is overwritten on the part program. The selection operation, editing operation, input of other operation commands, and the like necessary for this are performed via the input unit 13, and guidance and measurement results for inputting necessary information are displayed on the display unit 14. You.
[0015]
FIG. 2 is a block diagram of the operation restriction function realized by the computer 3 and necessary programs. The operator registration unit 21 associates a password, an operator name, operations that the operator can perform and available functions, and a total time T (hereinafter, referred to as an integration time T) when the operator uses the measuring device. I remember. The accumulated time T is obtained by measuring the time from login to logout by inputting a password by the timer 27 in FIG. 1 and cumulatively adding this time.
[0016]
The operator checking unit 22 checks the password input from the input unit 13 with the contents stored in the operator registration unit 21 to check the operator name. The all operation / function registration unit 23 is a part that stores an executable operation and a full list of available functions. The operation / function selection unit 24 is a part that generates an operation function mask M that limits operations that can be performed by the confirmed operator and usable functions. The operation / function permitting unit 25 is a part that extracts only the permitted operations from the operations / commands input from the input unit 13 based on the generated operation function mask M. The operation / function executing section 26 is a section for executing the operation / command extracted from the operation / function permission section 25.
[0017]
Next, among the operations of the three-dimensional measurement system shown in FIG. 1, an outline of the operation restriction function will be described with time.
Prior to the operation on the coordinate measuring machine 1 or the operation on the part program, the computer 3 prompts the operator via the display unit 14 to input a password. When the operator inputs a password from the input unit 13, the password is supplied to the operator confirmation unit 22.
[0018]
The operator confirmation unit 22 confirms the operator registered in the operator registration unit 21 via a password. If the password does not match any of the passwords registered in the operator registration unit 21, a warning is issued on the display unit 14 to prompt the user to re-enter the password. If the password matches one of the passwords registered in the operator registration unit 21, the name of the operator is displayed on the display unit 14.
[0019]
When the operator name is confirmed by the operator confirmation unit 22, a list of the operator name, operations that can be executed by the operator, and available functions is supplied to the operation / function selection unit 24.
The operation / function selection unit 24 generates an operation function mask M that limits the operations that can be executed by the operator and the available functions for all the operations and functions. The function mask M is output to the display unit 14 and the input unit 13 in addition to being output to the operation / function permission unit 25 as described later.
[0020]
Using the operation function mask M, the operation / function permission unit 25 extracts only the operations that can be executed by the operator and the functions that can be used by the input password.
The operation / function permission unit 25 displays the extracted operation name and function name on the display unit 14 and compares these operation name and function name with each command input from the input unit 13. If the two match, the output of the input command is permitted. The command whose output is permitted is executed by the operation / function execution unit 26.
This command includes, in addition to the operation command for the CMM 1, a command for reading, executing, and editing a part program stored in the part program storage unit 11, a registration / editing command for the operator registration unit 21, and the like. .
[0021]
FIG. 3 shows an example of a screen display on the display unit 14 when executable operations and available functions are restricted by the operation function mask M.
FIG. 3A shows, among the commands related to the measurement procedure, only the procedure of “reading the measurement procedure from a file (B)” and the procedure of “calling the measurement procedure (C)” in black characters. These procedures can be executed by moving the mouse pointer to the position and clicking. Other steps shown in light gray text are not executed by clicking with the mouse.
[0022]
FIG. 3B shows icons for instructing various specific measurements when “Execute measurement procedure (R)” is selected. The icons that can be selected are black outlines and cannot be selected. Icons are drawn with a light gray outline. In FIG. 3B, various functions related to the circle measurement are limited. As described above, the executable function and the non-executable function are displayed in different display states, so that the operator can easily determine the function. Instead of distinguishing between such display states, only executable functions may be displayed in a list format.
[0023]
FIG. 4 is a block diagram showing a detailed configuration of the operator confirmation unit 22 and the entire operation / function registration unit 232.
The operator confirmation unit 22 includes an operator recognition unit 221 and an operator time accumulation unit 222. The operator recognizing unit 221 collates the registration information registered in the operator registration unit 21 with the input password, and specifies an operator name and the like. The operator time accumulating section 222 is a section that counts the total time during which the operator is operating the system based on the accumulated time T registered in the operator registration section 21 and the time t measured by the timer 27. .
[0024]
The all operation / function registration unit 232 includes an operation / function detail registration unit 231 and a question registration unit 232. The operation / function detail registration unit 231 stores names of various operations / functions, necessary experience times (Ta, Tb, Tc, etc.) of system operations normally required for appropriately executing the operations / functions, and these. When the execution of the operation / function is permitted, information as to whether or not a predetermined question needs to be made is stored in association with each other. Here, as shown in FIG. 5, questions are made for the functions A and B when the required experience time is Ta and Tb, respectively, and the operation A and B is newly permitted to an operator. It is assumed that information indicating that this is unnecessary is stored. Further, it is assumed that information is stored that the required experience time is Tc for the operation C and that a question needs to be made when the operation C is newly permitted.
[0025]
The question registration unit 232 should be presented to the operator when it is necessary to perform a question and the operation or function recorded in the all operation / function registration unit 231 is to be newly permitted to the operator. This is the part that stores questions. For example, when the integration time T integrated by the operator time integration unit 222 exceeds Tc, the operation C is newly targeted for permission. In this case, a question related to the operation of C is read from the question registration unit 232 and displayed on the display unit 14. When an appropriate answer is input to this question, the storage content of the operator registration unit 21 is automatically updated, and the operator is permitted to perform the operation C.
If this automatic update is not desired, the user can manually change the storage contents of the operator registration unit 21 by selecting the "manual mode" in the input unit 13, and the automatic update is not performed. It may not be done.
In the above configuration, the input unit 13 and the operator confirmation unit 22 constitute a confirmation unit, the operator registration unit 21 constitutes a registration unit, the operation / function permission unit 25 constitutes a permission unit, and the timer 27 and the operator time integration. The section 222 constitutes a clock section, and the question registration section 232, the display section 14, and the input section 13 constitute a question section. FIG. 5 shows an example of the permission condition.
[0026]
Next, the operation of this embodiment will be described with reference to the flowchart shown in FIG. After the process is started (S10), the operator is requested to input a password by a so-called logon process (S20). The entered password is collated by the operator recognition unit 221 with the contents stored in the operator registration unit 21 (S30).
If there is no matching password (N), a warning is displayed on the display unit 14 and a request is made to re-enter the password (S40). If a matching password is confirmed (Y), the result is supplied to the operator time integrating unit 222, and it is determined whether or not the integrated time T of the operator exceeds a predetermined time (S50).
If the time has not exceeded the predetermined time (N), the process shifts to S110 to start accumulating the operation time. If the accumulated time T exceeds the predetermined time (Y), the list of operations / functions currently available for the operator stored in the operator registration unit 21 is compared with the operation / function details registration unit 231. Then, it is determined whether the operation restriction of some functions can be released (S60). If it is determined that there is nothing that can release the restriction (N), the process proceeds to S110. That is, when the “manual mode” in which the operation restriction is manually released is set in the input unit 13, it is determined that there is nothing that can release the restriction, and the process proceeds to S110.
[0027]
In S60, when it is determined that there is an operation or function that can release the restriction (Y), subsequently, it is determined whether or not a predetermined question needs to be made when newly permitting the operation or function. (S70). This determination is made based on the data of “necessity of question” registered in the operation / function detail registration unit 231 (see FIG. 5).
When it is determined that a question is necessary (Y), question data relating to the operation / function is read from the question registration unit 232 and displayed on the display unit 14 (S80). When the answer to the question is input from the input unit 13 by the operator, it is determined whether or not the answer is correct (S90). If the answer is correct (Y), the list of operations and functions that the operator can execute and use in the operator registration unit 21 is updated (S100), and the process proceeds to S110. Thereby, the restriction of the corresponding operation / function is released. If the answer is incorrect (N), the process proceeds to S110 without performing the update in S100.
On the other hand, if it is determined that the question is unnecessary in S70 (N), S80 and 90 are omitted, and the above update is performed in S100.
[0028]
In this way, when the operation / function restriction release procedure (S50-100) is completed, in S110, operation time accumulation is started (S110), and in S120-170, the operation determined in S50-100 is performed. The operation is restricted based on the contents of the restriction.
[0029]
That is, in S120, the operation / function mask M is generated by the operation / function selection unit 24 based on the registration contents of the operator registration unit 21 determined in this way. Subsequently, it is determined whether a predetermined operation or command has been input from the input unit 13 (S130). If there is no input (N), the process waits until an input is made. If it is determined that the input has been made (Y), it is determined based on the operation / function mask M whether the operation or the like is related to operation restriction (S140).
If the input operation or the like relates to the operation restriction (Y), the operation / command input from the input unit 13 relating to the operation is ignored, and the process returns to S120 to prompt the user to input again. When the operation / function is not related to the operation restriction (N), the operation / function corresponding to the operation / command input from the input unit 13 is executed by the operation / function execution unit 26 (S150).
[0030]
In this way, the above-described procedures of S130 to S150 are repeated until all necessary operations and the like are completed (S160), and when all the operations and the like are completed (Y of S160), the accumulation of the operation time is terminated (S160). (S170), all the operations are terminated (S180). In the flowchart of FIG. 6, S20, S30, and S40 correspond to a recognition step, S100, S110, and S170 correspond to a registration step, S120 and S130 correspond to a specific step, S140 and S150 correspond to a restriction step, S50, S60, S70, S80, S90, and S100 correspond to an update step.
[0031]
For example, when canceling the restriction on the reference function of the part program, a question concerning the duty of confidentiality is displayed, and the operator inputs an answer to the question from the input unit 13. If an appropriate answer is given, it is determined that the user has appropriate confidentiality and knowledge, and the restriction on the reference function of the part program is released. Then, the data of the operations executable by the operator and the available functions of the operator registration unit 21 are updated, and the result of the update is displayed on the display unit 14.
[0032]
Similarly, the function of editing the registered contents of the operator registration unit 21 and the all operation / function registration unit 23 can be set as a target for releasing the operation restriction as described above. Normally, this editing operation is set to be executable only by a system administrator. However, according to the present invention, an operator can obtain experience and proficiency similar to that of a system administrator based on accumulated time T and answers to questions. If so, the operator can be permitted to use such editing functions.
[0033]
In the above embodiment, the case where the present invention is applied to the three-dimensional measuring device 1 has been described. However, the present invention is not limited to this, and the image measuring device, the contour shape measuring device, the roughness measuring device, the true The present invention can be applied to any measuring device such as a circularity measuring device, a microscope, and a projector.
Further, in the above-described embodiment, only the configuration of one measuring device has been described. However, the computer 3 is connected to a plurality of measuring devices via a network such as a LAN, and the operator registration unit 21 is shared between the same type of measuring devices. Is also good. Further, the integration time T may be obtained by adding up the individual integration times of the same type of measuring instruments on the network.
[0034]
Further, information such as the operator registration unit 21 and the all operation / function registration unit 23 is collectively stored in a host computer on a network, and referred to from an individual measuring device or downloaded to an individual measuring device as necessary. You may be able to do it.
In addition, all the operation records of the operator, including the case where the operation is restricted and the case where the operation is permitted, are stored, and these records are used for judging the skill level of the operator or for preventing accidents and troubles. May be used.
[0035]
Further, in the above embodiment, when the accumulated time T has reached the predetermined time, the question is displayed on the display unit 14. However, regardless of the accumulated time T, the question is displayed based on the judgment of the operator himself. Alternatively, if the answer is correct, the operation restriction may be released.
Further, it is also possible to mask the registered contents of the entire operation / function registration unit 23 itself. For example, when the three-dimensional measuring machine 1 is used only for measurement of a special work for a certain period, a mask for extracting only operations and functions related to the measurement of the special work and the like is generated. As a result, only operators and functions related to the special work can be permitted to all operators only for a certain period of time, and other operations can not be permitted. It is possible to prevent an accident or the like from occurring due to a mistake.
[0036]
【The invention's effect】
As described above, according to the present invention, executable operations or available functions can be finely set based on operator-specific experience and proficiency. Operation restriction can be added.
[0037]
In addition, the operations and functions that can be executed are set directly for each operator according to the weaknesses and proficiencies of each operator, and as in the past, indirect and general evaluation results are obtained for each operation and function. It is not necessary to set the difficulty level and assign the difficulty level to each operator, which simplifies the setting operation.
