Definitions

  • the invention relates to a control panel for a measuring device with a housing having at least one operating and viewing window, the control panel having at least one optical key finger-operable by the operating and viewing window, and the optical key having a transmitting element and a receiving element.
  • Control panels for measuring devices have been known for decades in very different configurations.
  • a window provided in the measuring device housing is exclusively a viewing window, whereby readings can be read through this viewing window typically "on site", ie on the measuring device itself, but if necessary also settings of the measuring device-measuring range, parameterization, calibration data-can be displayed.
  • keys are provided for operation which can be actuated without opening the housing of the measuring instrument, for example in the form of membrane keys on the outside of the housing.
  • buttons are often provided within the housing of the meter, so that the meter can usually only be operated when the housing of the Meter is opened.
  • the control panels described above can be used with at least one finger-operable optical button a transmitting element and having a receiving element.
  • a finger-operable optical button emits with its transmitting element electromagnetic radiation, often in the infrared range, and the receiving element of the optical button is suitable for detecting at least electromagnetic radiation of the type emitted by the transmitting element.
  • optical key The functioning of such and per se known optical key is based on the fact that an actuating object approaching the optical key reflects to varying degrees the electromagnetic radiation emitted by the transmitting element, so that the transmitting element differs in different intensity from the reflected one, depending on the distance of the actuating object to the optical key Radiation is applied. This reflected radiation detected by the receiving element is then used to detect the "actuated" state.
  • the optical buttons are arranged with the control panel so behind the operating and viewing window of the meter housing that a finger operation of the optical button can be particularly well recognized when the operating finger on the control and viewing window on the optical button comes to rest in this Distance is thus given a sufficient reflection of the emitted electromagnetic radiation from the transmitting element.
  • a disadvantage of this solution is that an operation of a equipped with the known control panel measuring device is then no longer reliably possible when the housing of the meter is open, so that the panel is virtually free and is no longer protected by the control and viewing window , This situation occurs, for example, in the case of service, so in a situation where u. U. an increased need for adjustment exists and comparatively much data on the keys must be entered.
  • the otherwise prescribed by the operating and viewing window distance between the optical button and the operating finger is no longer defined and an intentional operation of the optical button is no longer distinguishable from an unintentional influence on the optical button.
  • the previously derived and indicated object is achieved in that in addition to the finger-operable optical key at least one corresponding finger-actuable mechanical button is provided, the control panel Thus, in addition to the finger-operable optical key, it has at least one corresponding finger-operable mechanical key.
  • a mechanical key corresponding to the optical key has a functionality comparable to the optical key, a similar event is triggered by actuation of a mechanical key corresponding to an optical key. It is advantageous that after removal of the operating and viewing window having housing the mechanical button can be operated and no longer has to resort to the optical button, which allows fast and still safe operation of the control panel having meter.
  • the optical key and the mechanical key can be arranged away from each other.
  • the mechanical buttons on the control panel are arranged so that they are not recognizable by the operating and viewing window of the meter housing - assuming a closed housing - for an operator, so appear only after opening the case ,
  • the mechanical button is arranged in the immediate operating range of the optical button. If it is mentioned that the additional mechanical key is provided in the "immediate operating range" of the finger-operable optical key, then it is meant that the optical key and the corresponding mechanical key in use are practically not operable independently, so for example in the field of one square centimeter or in the range of a few square centimeters. In particular, this is understood to mean that the optical key and the mechanical key are arranged relative to one another in such a way that, during the operation of the mechanical key fingering, the optical key is also necessarily finger-operated.
  • the actuating finger approaches the mechanical button and must, of course, the one immediately above the button traverse the room. If the corresponding optical button has its detection area right there, an actuation of the optical button upon actuation of the mechanical button can not be completely avoided.
  • control panel In a preferred embodiment of the control panel is provided that a keypad on the control panel is identified and the optical key and the corresponding mechanical key are arranged in the common keypad. This measure makes it clear to the operator of the control panel where to actuate in order to operate the desired key, irrespective of whether it is the optical key or the mechanical key corresponding to the optical key.
  • the optical button and the corresponding mechanical button are arranged side by side in the control panel, which especially allows a particularly simple realization of the control panel with standard components, as the optical button and the mechanical button not to be realized in unit.
  • the optical key is arranged at least partially in the mechanical key, in particular the transmitting element of the optical key or the receiving element of the optical key is arranged in the mechanical key.
  • the finger-operable optical key and the corresponding additional finger-operable mechanical key are realized as a structural and functional unit, which in particular makes it possible to force the mechanical key to be pressed during the operation of the finger also the optical key is finger-operated.
  • the transmitting element and the receiving element of the optical button are aligned with each other so that when fingering the mechanical button, so when resting the operating finger on the mechanical button, virtually none Reflection of the emitted radiation from the transmitting element of the optical button radiation in the receiving element of the optical button is possible.
  • virtual no reflection is meant that less than 10% of the maximum reflection when the operating finger rests on the transmitting element reaches the receiving element.
  • the transmitting element and / or the receiving element of the optical key are embedded in an optically tight holder such that the operating aperture of the holder of the transmitting element or of the receiving element is also optically closed when the operating finger rests on it ; In fact, a reflection can be completely excluded.
  • the control panel according to the invention is preferably equipped with at least one evaluation unit for detecting the operation of the optical button and the mechanical button.
  • the actuation detection of the keys can be done by a single evaluation, but it can also be done by multiple evaluation.
  • the evaluation unit is set up in such a way that it deactivates the optical key as soon as the mechanical key-with the housing of the measuring instrument open-has been actuated. If a plurality of finger-operable optical keys are implemented with a plurality of corresponding finger-operable mechanical keys, the evaluation unit is preferably designed such that all optical keys are deactivated when a mechanical key has been actuated. This special embodiment of the evaluation unit of the control panel can be prevented that an incorrect operation of the panel occurs.
  • a potential incorrect operation results solely from the fact that when pressing the mechanical button at the same time or just before the corresponding optical button is triggered, it would be detected an unwanted double triggering.
  • a deactivation of the optical key can be achieved by various alternative or jointly feasible measures; the transmitting element can be switched off, the receiving element can be switched in circuit in a defined and independent of the external state of influence state or the evaluation of the received signal supplied by the receiving element by the evaluation unit can be set, for example.
  • another evaluation unit is preferred intended as for the realization of the deactivation / activation of the optical buttons.
  • the deactivated optical key is automatically reactivated by the evaluation unit after a defined predetermined time and / or the deactivated optical key is reactivated by an actuation pattern of the corresponding mechanical key, thus for example by a mechanical key within a short time Time is pressed several times.
  • the deactivated optical buttons are activated by the combined simultaneous operation of at least two mechanical buttons again by the evaluation unit.
  • the evaluation unit evaluates the intensity of the radiation received by the receiving element, in particular evaluates the temporal course of the intensity, preferably by scanning the receiving element in a fixed time grid.
  • the evaluation unit declares the optical key as "actuated” upon detection of a constant intensity of the radiation received by the receiving element over a defined predetermined period of time, ie provides a corresponding actuation signal.
  • the evaluation unit not only detects whether the constant intensity is present for a certain period of time, but also whether the intensity is within a predetermined range, which can additionally avoid misrecognition of the actuation state, for example due to extraneous radiation.
  • the control panel according to the invention also has the advantage that it provides a "fast" possibility of operation via the mechanical keys corresponding to the optical keys, because the optical keys - In any case, compared to the mechanical buttons-relatively slowly respond. This is mainly due to the fact that - as indicated above - the evaluation of the received signal supplied by the receiving element for the reliable generation of a detection signal requires quite considerable effort in the signal processing.
  • FIGS. 1 and 2 is shown in each case a control panel 1 for a measuring device with an operating and viewing window having housing, the meter is not shown in total, so not the housing with a control and viewing window,
  • the control panel 1 has a total of four finger-operable optical buttons 2, the optical buttons 2 each having a transmitting element 3 and a receiving element 4.
  • the transmitting elements 3 are infared transmitting diodes and the receiving elements 4 are infrared receiving diodes.
  • the infrared radiation emitted by the transmitting elements 3 is reflected to a different extent by an actuating force approaching the optical keys 2 as a function of the spacing of the finger from the transmitting element 3.
  • a differently sized entry of infrared radiation occurs at the respective receiving element 4.
  • the various optical buttons 2 are arranged side by side under a display panel 5, so that the optical buttons 2 can not influence each other and in particular can be operated so that the display panel 5 is not obscured during operation.
  • each mechanical key 6 is arranged in the immediate operating range of the optical key 2 corresponding to it, the immediate operating range of the optical key 2 being understood to mean that in practical use upon actuation of the finger-actuable mechanical key 6 respectively the corresponding finger-operated optical key 2 is triggered.
  • Fig. 1 is on the control panel 1 for each optical key 2 and for each of the respective optical key 2 associated mechanical key 6 each provided a keypad 7 on the control panel 1, each with an optical key 2 and the corresponding mechanical key 6 each in a keypad 7 are arranged together.
  • Fig. 1 These are oval keypads 7, in the case of the control panel 1 in Fig. 2 this is a circular keypad 7. In this way is clear to the operator - apart from the already existing arrangement of the mechanical button 6 in the respective immediate operating range of the optical button 2 by a label where in the control panel 1 related optical and mechanical buttons are provided.
  • Fig. 1 are each the optical button 2 and the associated mechanical button 6 in the control panel, in this case also in the common keypad 7, juxtaposed - ie side by side - arranged in the present case, the two buttons in Fig. 1 arranged one above the other.
  • each of the transmitting element 3 and the receiving element 4 of the optical buttons 2 are aligned such that the detected by the receiving element 4 reflection maximum is spaced from the surface of the mechanical button 6 and the reflection maximum thus at a distance from the surface of the Control panel 1 is located.
  • Fig. 1 and 2 are the transmitting element 3 and the receiving element 4 of the optical button 2 aligned with each other so that when fingering the mechanical button 6, so when resting the operating finger on the mechanical button 6 virtually no reflection of the emitted from the transmitting element 3 of the optical button 2 infrared radiation in the Receiving element 4 of the optical button 2 is possible.
  • This is according to the embodiment Fig. 1 ensures that the optical button 2 is located in close proximity to the corresponding mechanical button 6, so that when fingering automatically especially the transmitting element 3 is covered, so that no more infrared radiation reaches the relevant reflection range of the optical button 2.
  • a control panel 1 in which the optical button 2 is partially arranged in the mechanical button 6, namely by the transmitting element 3 of the optical button 2 is arranged in the mechanical button 6.
  • the outline of the mechanical button 6 is indicated by a dashed line.
  • the optical button 2 and the mechanical button 6 are here arranged to each other so that during the process of fingering the mechanical button 6 - approach of the actuating finger to the buttons 2, 6 - necessarily the optical button 2 is finger-operated, as well as the emission of Infrared radiation practically safe and compelling when fingering the mechanical button 6 - resting the actuating finger on the mechanical button 6 - is prevented.
