Description

Device and method for inputting and displaying numerical values and corresponding system

Technical Field

The invention relates to a device and a method for inputting and displaying values and a corresponding system. In particular, the invention also relates to a system for examining a sample. The test specimen is intended to mean in particular the electronic device to be tested.

Background

In the case of testing electronic samples with regard to suitability, professional (spezialiniert) testing devices are often used. Such a test device can, for example, generate an input signal for the sample and receive and analyze an output signal of the sample on the basis of the input signal. Furthermore, the test device can determine a target value, which the output signal of the test specimen should ideally receive, by means of model calculations. For a complete test, it is advantageous to be able to rapidly change an input signal or a large number of input signals for the sample and/or the model calculation. The input signal or signals can in particular be target values.

For such test devices, special display and control devices are often used, which can also be referred to as operating computers, operating personal computers or, in english, as operating PCs. By means of the software executed by the display and control device, the test device can be controlled in real time and the values output by the test device can be displayed in real time. Such a System comprising a test device and a display and control device is also referred to as a Hardware-in-the-loop System (abbreviated as: HIL-system. Such display and control devices, i.e. devices for displaying and inputting values, are often particularly compact in order to be able to be transported and used in a versatile manner. Thereby, the position on the device that can be used for displaying and inputting numerical values is limited.

Traditionally, a rotary adjuster element is used to set the value, while a pointer element is used to display the value. A conventional pointer element is described in EP 0805340B 1, which has a pointer finger (Zeigerfahne) fixed to a rotatably mounted hub.

There is therefore a need for a device for displaying and inputting values, by means of which the values can be displayed and input in a particularly space-saving manner and by means of which the values to be input can be input particularly quickly and accurately.

Disclosure of Invention

An apparatus, a system, and a method having features of the present invention are disclosed.

Accordingly, a device for inputting and displaying values is provided, which has: a numerical value scale; a first indicator mechanism and a second indicator mechanism by means of which a value can be indicated on the value scale, wherein the first indicator mechanism is adjustable by a user for indicating on the value scale a first value to be entered; a control mechanism designed to determine a first value indicated by the first indicator mechanism; interface means by means of which the determined first value can be transmitted to a further device and by means of which a second value generated by the further device on the basis of the transmitted first value can be received; wherein the control mechanism is designed to: automatically adjusting the second indicator mechanism based on the received second value for indicating the second value on the value gauge.

The numerical value table can in particular be a numerical value table, which has numerical values as numerical values. However, a numerical table having as numerical values symbols or states, such as "too large", "too small", "allowed", "not allowed", "unknown" or similar symbols or states, is also conceivable.

The indication of a numerical value shall in particular mean that the respective indicator means particularly explicitly represent the numerical value of the numerical scale, such as by pointing to the numerical value, by illuminating or backlighting the numerical value, by making the numerical value visible, by circling the numerical value or the like.

The first and second values preferably relate to the same variable, in particular a physical variable, such as the rotational speed of a shaft or a motor, or the like.

The further device can in particular be a test device, i.e. a device which is designed for examining the sample using the first value and/or for calculating a model value on the basis of the first value. The further device can also be an adjusting device or an actuator device.

Furthermore, the invention provides a system having a device according to the invention and having a further device, which is designed to: the second value is generated on the basis of the first value received by an interface means of the device and transmitted to the interface means.

Furthermore, the invention provides a method for inputting and displaying numerical values, having the following steps: adjusting, by a user, a first indicator mechanism for indicating a first value on a value scale; determining the indicated first value; generating a second value on the basis of the determined first value; and automatically adjusting the second indicator mechanism such that the second indicator mechanism indicates the second value on the value gauge.

The invention is based on the recognition that one and the same value scale can be used both for indicating a value to be entered and for indicating at least one value to be displayed. The invention thus provides a particularly space-saving possibility for simultaneously displaying the second numerical value and for inputting the first numerical value, in particular in real time. The user can change the value to be entered on a single value scale, and can directly read the result of this change. This reduces the possibility that the result of modifying the value to be input is overlooked by the user.

A large number of values can be displayed by a correspondingly large number of indicator mechanisms, for example two, three, four or even more indicator mechanisms, without additional position requirements arising. The device can thus also be constructed more compact or provide the function of an additional consumption location in keeping the same size.

The invention provides a particularly intuitive operation of the device according to the invention, in particular if the values to be entered, i.e. the first value, and the values to be displayed, i.e. the second value, are logically linked to one another. Even when there is a small difference between the first and the second numerical value, it can be easily visually identified whether the numerical values are different from each other and how severe they are.

Advantageous embodiments and developments emerge from the dependent claims and from the description with reference to the figures.

According to an advantageous further development of the device according to the invention, the first and second indicator means are designed in such a way that, if both the first and the second indicator means indicate the same value on the value scale, both the first and the second indicator means are recognizable to the user. Likewise, it is possible to use further indicator means for processing, in particular if said indicator means are visually displayed on the screen means. In this way, it is possible for the user to comfortably read out both the first and the second value and, if appropriate, also the further value at each time.

According to a further advantageous development, the device comprises a screen device, by means of which the numerical quantity table and/or the first and/or second indicator device can be displayed. The value scale can thus be flexibly adapted, for example automatically, to the connected test device and/or to the sample to be examined.

According to a further advantageous development, the numerical value scale is designed as a linear, elliptical, circular or circular segment-shaped numerical value scale, in particular as a numerical value scale. In particular, the numerical values of the numerical value scale can thereby be displayed in a space-saving and particularly at a glance.

According to a further advantageous development, the device comprises at least one numerical display means which is designed to display the first numerical value displayed by the first indicator means and/or the second numerical value indicated by the second indicator means and/or possibly further numerical values in numerical form. This enables the indicated value to be read out particularly quickly and precisely and at the same time in a space-saving manner.

According to a further advantageous development, the further device of the system according to the invention is designed to: the second value is generated on the basis of the first value using a calculation model stored in the further device.

According to a further advantageous development, the further device is a test device which is designed to generate the second value by: it transmits the first value to the sample to be examined and determines the value resulting from the sample as a reaction to the transmitted first value as the second value.

According to a further advantageous development, the first and/or second value and, if appropriate, further values are each an actual value, a target value, an estimated value or a measured value with respect to the same variable. This allows the user to directly and intuitively recognize that the values relate to the same value range and, for example, have the same limit value.

Detailed Description

Fig. 1 shows a schematic block diagram of a device 10 for inputting and displaying values according to an embodiment of the invention and a system 1 according to another embodiment of the invention. The device 10 comprises a value gauge 16 and first and second indicator means 21, 22 by means of which a value can be indicated on the value gauge 16.

For example, the value scale 16 can be configured as a linear, elliptical, oval segment-shaped, circular or round segment-shaped, for example horseshoe-shaped, value scale. The pointer means 21, 22 can be formed or displayed as a physical pointer (Zeigerfahne) or preferably as a virtual pointer. Each pointer finger can be constructed or displayed with different lengths, widths, shapes, and/or colors.

The first indicator means 21 can be adjusted, in particular moved, rotated and/or pressed, by a user for indicating on the value scale 16 a first value 51 to be entered. By means of the control means 14 of the device 10, the first value 51 indicated by the first indicator means can be determined. Furthermore, the device 10 comprises an interface means 18, by means of which the determined first value 51 can be transmitted to a further device 60 and by means of which a second value 52 generated by the further device 60 on the basis of the transmitted first value 51 can be received. Control mechanism 14 is designed to automatically adjust second indicator mechanism 22 based on the received second value 52 for indicating the second value 52 on the numeric scale 16.

The device 10 and each of the subsequently described alternatives or variants of the device 10 can be implemented in hardware or in software or in a hybrid form of hardware and software, respectively. For example, the first and second indicator means 21, 22 can comprise physical pointer fingers, wherein the position of the first indicator means 21 with respect to the numeric scale 16 is detected mechanically or electronically by the control means 14.

As also shown in fig. 1, the system 1 according to the invention comprises the device 10 and the further device 60. The further device 60 can be designed for: the second value 52 is generated on the basis of the first value 51 on the basis of a calculation model stored in the further device 60. In addition or alternatively, the further device 60 can be designed to generate the second value 52 by: it transmits the first value 51 to a sample 70 to be examined and determines the value resulting from the sample 70 as a reaction to the transmitted first value 51 as the second value 52 or as the third value.

The further device can be, in particular, a test device 60. The further device is described below for the purpose of explanation as a test device 60. However, the further device can also be, for example, a control device or an actuator device, which receives the first value as a target value for a predetermined variable and generates an actual value for the same variable as a second value and transmits it to the device 10. For example, the further device can be a Thermostat (Thermostat).

The test specimen 70 can be, in particular, an electronic device, preferably in or for use in a motor vehicle. For example, the test piece can be an Electronic Control Unit (ECU) for a motor vehicle, in particular for a drive of a motor vehicle. The test device 60 can also have an analog sensor device, for example, which can be used to generate the second value 52 or the fourth value.

Fig. 2 shows a schematic block diagram of an apparatus 110 for inputting and displaying numerical values according to yet another embodiment of the invention.

The device 110 is a variant of the device 10 and can also be included in the system 1 or a variant thereof. Furthermore, the device 110 comprises a screen mechanism 112 by means of which the numerical gauge 116 and the first and

second indicator mechanisms

121, 122 can be displayed graphically.

Fig. 3A to 3C partially show the numeric scale 116, the first indicator mechanism 121 and the second indicator mechanism 122 displayed by the screen mechanism 112 in three different cases.

The numeric scale 116 is configured as a horseshoe-shaped numeric scale according to fig. 3A, with exemplary numeric values of minus six thousand to plus six thousand. The first indicator mechanism 121 is embodied and illustrated as a bar (Balken) 124, which, like a physical pointer, is fastened at a first end to the center point 115 of the value scale 116 in a rotatable manner, while the unfixed second end of the bar 124 indicates the numerical value (Zahlenwert) on the value scale 116. Instead of a bar, the first indicator means 121 can also be embodied, for example, in the form of an arrow, a triangle, or the like.

The first indicator mechanism 121 can be rotated by a user so that a numerical value on the numerical gauge 116 can be indicated by means of the second end of the bar 124. The rotation of the lever 124 can be performed, for example, by means of a pointing mechanism, which can be connected to the device 110. The pointing mechanism can be, for example, a computer mouse, a Trackball (Trackball), a Joystick (Joystick) or a touch screen, which can be connected to the device 10 or integrated into the device 10. For example, the screen mechanism 112 can be designed as a touch screen and can thus also function as a pointing mechanism. A pointer 150, such as a mouse pointer, of the image moved by the pointing mechanism can be controlled to change its appearance, such as by an arrow, to a hand shape when it is directed to a portion of the value gauge 116 or onto the bar 124, see fig. 3B.

This value can be indicated on the value scale 116 by clicking or pressing the bar 124 with the aid of the pointer 150 of the pointing mechanism, for example with the aid of a computer mouse, moving the bar 124 over the first value 51 to be entered and releasing the bar 124 over the first value 51 to be entered (so-called "drag-and-drop" -method). The value thus indicated is automatically determined by the control unit 114 as the first value 51 to be entered.

Furthermore, the gauge 116 can have at least one identified region 140 that can be activated for precisely adjusting the first indicator means 121 to a value predetermined for each identified region 140. If the identified area 140 is configured as a mechanical button or a touch-sensitive control surface, for example, the activation can be performed by pressing the identified area. Fig. 3B shows a situation in which the identified region 140 is represented by an image by the screen mechanism 112 and can be clicked by means of the pointer 150. By clicking on the identified region 140, in fig. 3B for example the identified region 140 assigned to a value of minus three thousand, the first indicator means 121 jumps immediately to this value as shown in fig. 3C, while the second indicator means 122 indicates for example minus two thousand, three hundred and fifty as the correspondingly generated second value 52. The pointer 150 can be configured, for example, to change its appearance when positioned over one of the identified regions 140, such as by an arrow to a hand.

It can be provided that any value can be indicated on the value scale 116 by the first indicator means 121. Alternatively, it can be provided that only certain values, for example (unsch ä dlich) values which are permissible or harmless for the test specimen 70, are indicated on the value scale 116. The control mechanism 114 can be configured to: information is automatically obtained from the sample 70 by the interface device 18, for example by the further device, in particular the test device 60: which values are permissible or harmless for the test sample 70 or the further device, in particular the testing device 60, and then the indicator means 121 is correspondingly represented in an adjustable manner. The permissible regions for the first indicator means 121 can be indicated on the value scale 116, for example, in color or in a backlit manner.

The determined first value 51 is transmitted by the control means 114 as a first digital or analog signal to the interface means 18 of the device 110, via which the first signal is automatically transmitted to the test device 60 connected to the interface means 18. The test device 60 can be, in particular, a real-time computing device (RTPC). The test device 60 can be designed to: in a real-time-capable (echtzeitf ä hig) environment, a calculation model is generated and/or evaluated using the transmitted first signal and/or the transmitted first value 51. On the basis of this, the test device 60 generates a second value 52, which can be transmitted to the interface means 18 by means of a digital or analog second signal. Instead of or in addition to the use of a calculation model, the test device 60 can also be designed to: the first value 51 is transmitted to the sample 70 and the reaction of the sample 70 to the first value 51 is determined as the second value 52 and/or as a third value, which can be transmitted to the interface unit 18.

The second value 52 transmitted to the interface means 18 is transmitted to the control means 114, which automatically controls the second indicator means 122 for indicating the second value 52 on the value scale 116. The second indicator means 122 is configured as a virtual pointer finger, so that if the first and second indicator means 121, 122 indicate the same value on the value scale 116, the second indicator means neither covers the bar 124 of the first indicator means 121 nor is covered by the bar of the first indicator means. In other words, both the first and the

second indicators

121, 122 are advantageously always readable, for example by: the indicator means lying further down in the image plane shown are displayed wider than the indicator means lying further up.

Fig. 3D partially illustrates an alternative display, shown by the screen mechanism 112. This display includes a value gauge 116, a first indicator mechanism 121 and a second indicator mechanism 122. Furthermore, the display comprises a third indicator means 123 and a first to third display means 231, 232, 233 of numerals, which optionally can also be part of the device 110.

The third indicator mechanism 123 is designed to: a third value transmitted to the interface mechanism 18 is indicated on the value scale 116. In particular, the third value can be generated by the test device 60 and/or the test specimen 70 on the basis of the first value 51 and transmitted to the interface unit 18. For example, the second value 52 can be a model value known from the test device 60, and the third value can be a value known as a test sample 70 by the ECU, for which the first value 51 input by the user is a desired target value, input value, or comparison value.

The numerical first, second and third display means 231, 232, 233 indicate the numerical values by means of numbers, respectively, the first, second and third indicator means 121, 122, 123 indicating the numerical values on the numerical scale 116, respectively. The first display mechanism 231 can be designed to: can be adjusted by the user through numerical input. This can be done, for example, by means of a keyboard, keypad or the like, which can be displayed accordingly by the screen mechanism 122 or can be formed physically and connected to the device 110. Fig. 3D shows a situation in which the user has, for example, entered the value "3333" into the

first display mechanism

231, 232, 233 of the number. The first indicator means 121 is then adjusted by the control means 114 for indicating the value "3333" on the value gauge 116. According to an exemplary calculation or test of the test device 60, the numerical second and third display means display "3335" as the second numerical value 52 or as the third numerical value, respectively.

The first numerical value 51 can be entered particularly precisely by means of the first display 231 of the adjustable number. The second and third

numerical values

52, 233 can be read particularly precisely by means of the numerical second and third display means 232, 233. The first, second and third indicator means 121, 122, 123 and the first, second and third display means 231, 232, 233 of the numbers are advantageously each formed in pairs with the same color, so that it is directly clear to the user which indicator means and which display means of the numbers relate to the same numerical value. For example, the bar 124 of the first indicator means 121 and the edge 234 of the first display means 231 of the numbers can be shown in blue, while the pointer of the second indicator means 122 and the edge 235 of the second display means 232 of the numbers are shown in red and the pointer of the third indicator means 123 and the edge 236 of the third display means 233 of the numbers are shown in green.

Fig. 4 shows a schematic flowchart for explaining a method for inputting and displaying numerical values according to a further embodiment of the invention. The method according to fig. 4 can be carried out in particular with one of the devices according to the invention, in particular one of the

devices

10, 110, and can be adapted to all variants and modifications described with respect to the devices according to the invention, in particular with respect to the

devices

21, 121 is adjusted by the user for indicating the first numeric value 51 on the

numeric scale

16, 116. The indicated first value 51 is determined in step S02. In step S03, the first determined value 51 is transmitted to the test device 60. In step S04, a second value 52 is generated or calculated by the test device 60 on the basis of the transmitted first value 51. In step S05, second indicator means 22, 122 is adjusted, in particular rotated, and/or moved in such a way that second indicator means 22, 122 indicates second value 52 on

value scale

16, 116.
