Description

  • The The invention relates to a measuring device with a meter housing, with a measuring device for carrying out of a measurement result supplying a measurement result on one or in Terms of an outside of the measuring device lying measuring location and with a disposed within the meter housing, indicating the measurement result indicating device.
  • It There are a number of methods and devices known to the respective measured variable at the measuring location to make visible. For example, there are thermographic recordings in which a kind of photo of a house front being taken, being in the photo by different colors the different heat radiation of windows, walls, Isolations etc. is made visible. The known methods and devices for visualizing the measurement results directly at the measuring location, such as thermographic images, are regularly consuming and at a high cost.
  • As an alternative to the methods and devices, which clearly show the measuring location and measurement result by means of, for example, a photo-like image, there are a multiplicity of measuring devices, in particular also small handheld measuring devices, which are held in the direction of the measuring location and the respective measurement result on a display device eg in the form of a display, usually an LCD display ( DE 44 44 046 A1 . DE 43 12 583 C2 . DE 34 32 511 C2 . DE 37 34 365 A1 ). For example, there are non-contact thermometers, which are aimed at the respective locations of a building and which then display the measurement result for the temperature at the respective measuring location in the display. In addition, methods and devices are known in which the measurement result in the vicinity of the measurement location is displayed on a separate surface, in particular also by light projections ( DE 44 09 398 A1 . DE 2 104 081 A1 . DE 2 118 809 A1 . DE 35 32 301 A1 . DE 41 37 666 A1 ) or the measurement result is stored on a separate medium for later evaluation ( DE 195 08 338 A1 . DE 39 08 069 A1 . EP 0392 163 A2 ).
  • at the aforementioned methods and devices, in particular also the inexpensive, less expensive handheld meters is especially problematic, that in cases where this is relevant, location and measurement not common can be detected at a glance. The operator receives no clear Display of measurement results on or immediately next to the measuring location, the connection between measuring location and measuring result is determined by the Display on a separate device or area torn apart, which for the Operator has an unergonomic handling result. from time to time it also lacks an overall picture of the course of the measurement results. The well-known handheld instruments are therefore very limited in their ability to to recognize at which Place of a house front given off most of the heat or where the sound penetrates the wall the most. The Cause for the limited Suitability of the known measuring instruments lies in their unergonomic Type of display, but vice versa just for the compact design, the Low power consumption and the low price of such instruments crucial is. Based on the problem described above is the Invention the task is based, a measuring device with an improved display device to disposal to provide an ergonomic representation of a measurement result guaranteed with reference to a measuring location.
  • According to one first teaching of the invention is the previously derived and shown Task solved by that the display device, the measurement result at least qualitatively on or immediately adjacent to the measurement location regardless of the meter housing. By the inventive display of the Measurement result on or immediately adjacent to the measuring location is for the operator in a particularly ergonomic way a relation between the Measuring location and the measurement result produced. It is not in particular necessary, the view constantly between the measuring location and an LCD display on the meter housing and let it wander. It is on the contrary so that the ad the result of the measurement and the indication of the measuring location very simple linked together.
  • has the display device a the measurement result on or immediately next to the measuring site projecting light projection device, this ensures that quickly ascertainable measurement results almost instantaneously at the measuring location can be displayed. Also with a light projection device longer distances to bridge that For example, the scanning of a building wall with a meter according to the first To enable teaching of the invention.
  • A Particularly ergonomic reproduction of the measurement result at the measuring location arises when the light projection device the measurement result represented by projections of corresponding intensity or color. A Such conversion of the measurement results in light different Intensity or Color possible for the Operator a particularly easy access to the qualitative classification the result of the measurement.
  • Does it require the respective measurement task that the exact numerical value for the measurement result at the measuring location is known, the measuring device according to the first teaching of the invention is advantageously configured in that the light projection device projects the numerical value for the measurement result directly next to the measuring location. The embodiment described allows a direct, very simple assignment between the measuring location and the quantitative measurement result. For this refinement, it makes sense, as a further improvement, to identify the exact measuring location in addition to the projected numerical value unambiguously, for example by the projection of a crosshair.
  • The Light projection succeeds particularly unproblematic when the light projection device includes a laser. The currently available inexpensive semiconductor lasers allow also over longer distances a sufficiently sharp and bright projection. In addition to use However, a laser for light projection also offers other light sources, e.g. also video projectors, for large-scale display of the measurement results on a test object.
  • If so far with regard to the measuring location and the projection of one Test object is mentioned, so this is not restrictive too understand. For example, there are also measurements on certain, none Dedicated spatial points possible, in which case the display of the Measurement result at the site by holographic method is possible.
  • alternative for displaying the measurement results by means of a light projection device is the measuring device according to the first Teaching of the invention configured by the fact that the display device a reproducing the measurement result by appropriate material order Has material application device. This embodiment of the first Teaching the invention allows on the one hand because of the durability a better overview in more complex measuring tasks and on the other hand due to the Proximity to Measuring object given larger possible Time to record the measurement result, the processing of measurement tasks, where the determination of the measurement results a certain period of time requires.
  • A at least qualitative reproduction of the measurement results is in the just described embodiment ensures that the material application device the measurement result by varying degrees or different colored material application.
  • is the meter according to a further embodiment of the first teaching of the invention thereby configured, that the meter portable - especially as a handheld device - trained is, then results in an alternative embodiment of a meter over the known, elaborate and expensive measuring equipment, which ensures that complicated measuring tasks simultaneously cost-effective and ergonomic manageable are.
  • The However, the first teaching of the invention includes not only portable, handy Measuring device, but also elaborate, stationary Measuring device, However, in their handling compared to the known measuring devices clearly are improved. So it is with the first teaching of the invention, for example possible, a thermographic recording by means of a video projector on the Project the object to be measured. Such a projection of a thermographic recording on, for example a house front or the part of a house front improves the vividness or ergonomics of the display many times over.
  • The second teaching of the invention relates to a display method for a measuring device with the help a measuring device for carrying out a measurement process supplying a measurement result on or in relation to on an outside of the measuring device lying measuring location and with the help of a arranged within a meter housing, indicating the measurement result indicating device. The second too Teaching the invention underlying, initially presented task is according to the second teaching solved by the invention that the measurement result from the display device at least qualitatively displayed on or immediately adjacent to the measurement location, regardless of the meter housing becomes. By the realization of the second teaching of the invention guaranteed Advantages correspond to those already in connection with the first teaching The advantages described in the invention.
  • The Method according to the second Teaching the invention is first configured particularly advantageous that the measurement result only displayed when a minimum and / or maximum value is reached becomes. This embodiment of the method according to the invention allows the Operator particularly easy to find the location-dependent minimum and / or maximum values of the measurement results.
  • If there is no urgent need for precise determination of the measuring location for the minimum and / or maximum values, but for a particularly clear display, then the method according to the second teaching of the invention is particularly advantageously characterized in that the measurement result is now in the environment of Minimum and / or maximum value - especially in a ± 10% environment - is displayed. In this case, for example, when using a laser as a light projection device for the operating person clearly visible light line.
  • in the Individual there are a variety of possibilities, the measuring device according to the invention or the Display method according to the invention for a gauge to design and develop. On the one hand on the the claims 1 and 6 subordinate claims and on the other hand also the description of a preferred embodiment in connection referenced with the drawing. In the drawing shows the only figure schematically an embodiment a measuring device according to the first Teaching the invention.
  • The measuring device shown in the single figure has a meter housing 1 , a measuring device 2 for performing a measuring operation providing a measurement result and one within the meter housing 1 arranged, indicating the measurement result indicating device 3 on. In addition, in the single figure is a drive unit 4 represented, the different relationships between the measurement result and the measurement location on a measurement object also shown in the single figure 5 can realize.
  • In the single figure are the measuring device 2 , the display device 3 and the drive unit 4 housed together in the meter housing. However, it is also conceivable a separate arrangement of the components of the meter in different Gehäsen. As a meter housing in the context of the invention, the housing is always referred to, in which the display device 3 is arranged.
  • In the single figure, a first arrow indicates 6 the sensitivity direction of the measuring device 2 at. The first arrow 6 is not necessarily the only direction of the sensitivity of the measuring device 2 to interpret, but as the mean sensitivity direction of the measuring device 2 ,
  • The second arrow 7 now describes the direction in which the display device 3 displays the measurement result. In the single figure, both arrows hit 6 . 7 at the measuring location 8th exactly together. Such an exact coincidence is initially not necessary for every measurement task. However, if the exact coincidence is necessary for a measuring task, the distance between the measuring device housing should also be taken into consideration during this measuring task 1 and the measurement object 5 vary, so it may be necessary for optimal projection, a distance determination between the meter housing 1 and the measurement object 5 perform in a known manner. As an alternative to this, it is conceivable that the display device is adjusted manually or automatically-for example in an adjustment mode-so that the spatial coupling between the measured value display and the measurement object is ensured. For example, the display device could generate a pattern on the measurement object that is recognized by the measurement device and used for adjustment between the measurement object and the display device.
  • The measuring device 2 is, for example, sensitive to one of the measured variables temperature, sound level, brightness, color, presence of metal. The display device 3 may be formed for example as a laser pointer, video projector, chalk marking device or inkjet printer.
  • The use of a laser pointer as a display device is suitable for example when measuring a sound level in the vicinity of a door. The laser pointer draws a light line on the door, which is the brighter the more sound the meter has measured in the respective measuring direction. The operator can thus directly detect whether the door leaf lets the sound through or whether the sound passes through a gap. A laser pointer is suitable as a display device 3 Also in conjunction with a non-contact thermometer to replace a thermographic recording. In this case, one can read the intensity of a visible laser line on the facade of a house where most of the heat is lost.
  • The use of an ink print head as a display device 3 is particularly suitable for connection with a metal detector. A metal detector designed in accordance with the invention generates a line on the wall when scanning a wall, which indicates either in its thickness or its color exactly where the metal detector has detected metal. Thus, a safe drilling in a wall is possible, in which, among other things, water pipes are laid. As a display device for metal detectors on a larger scale, so eg metal detectors for use on construction sites, for example, is a chalk line device. With a measuring device designed in this way, it is possible to permanently and clearly mark the position in an area to be excavated, in the surroundings of which special care must be taken when excavating.
  • Next the already mentioned possibilities the qualitative or quantitative indication of the measurement result There is a special possibility on or immediately next to the site the qualitative indication in the display of certain measurement results assignable texts, such as in temperature scanning a facade of the text "Attention: Window is on, "about for the Case that particularly high temperatures are measured.
