Description

[0001] MEASURING DEVICE HOUSING FOR MOUNTING TO

[0002] MEANS OF TRANSPORTATION

[0003] The invention relates to the field of measuring device housings for ground-contact-free attachment to a means of transport, wherein the measuring device housing comprises a measuring device location for a measuring device. The measuring device uses electrical, magnetic, and / or electromagnetic radiation and / or fields to acquire information about a target object in an environment of the measuring device housing. The invention relates to a measuring device housing according to the preamble of the corresponding independent patent claim.

[0004] Such a measuring device housing is known, for example, from WO2010 / 101630. A measuring device housing is described that has measuring device locations for two measuring methods, in this case, ground-penetrating radar and metal detector.

[0005] Known measuring device housings have the disadvantage that, due to the ground-free attachment to a means of transport, a supporting housing is formed, which must be constructed accordingly solidly. Due to the interference of electromagnetic fields in and around the measuring device housing caused by the solid construction of the measuring device housing, measurements from the measuring device must be corrected and / or calibrated. To minimize the influence of the measuring device's measurements, known measuring device housings are complex in design and / or feature complex shielding devices.

[0006] In conventional measuring device housings, the measuring device housing or even the measuring device contained therein can be damaged if the measuring device housing moves along with the vehicle and, for example, strikes the ground or elsewhere. For this reason, state-of-the-art measuring device housings have a complex design to ensure a high degree of stability while maintaining low weight and minimizing the influence of electromagnetic fields. Such measuring device housings are complex to design and manufacture, and production, repair, and maintenance are correspondingly costly and time-consuming.

[0007] It is therefore an object of the invention to provide a measuring device housing of the type mentioned at the outset which at least partially eliminates at least one of the disadvantages mentioned above.

[0008] This object is achieved by a measuring device housing having the features of the corresponding independent patent claim. Advantageous embodiments can be found in the dependent claims, the description, and / or the figures.

[0009] The measuring device housing according to the invention is designed for ground-contact-free attachment to a means of transport and comprises a measuring device location for a measuring device. The measuring device serves to acquire information about a target object in a measuring range in the environment of the measuring device housing. To this end, the measuring device uses electrical, magnetic, and / or electromagnetic radiation and / or fields. The measuring device housing consists of at least 95 percent by weight of material other than ferromagnetic metal. The measuring device housing also has an overload area, which serves as overload protection against mechanical forces.The measuring device housing is designed such that the overload area can be moved from a normal position to an overload position spaced relative to this contact point upon contact with a contact point in a floor area in the vicinity of the measuring device housing.

[0010] The measuring device housing encloses the measuring device location, but not the measuring device itself. The measuring device housing can accommodate two measuring device locations, for example, for two different functioning measuring devices. In particular, three measuring device locations are possible, for example, for three different functioning measuring devices. More than three measuring device locations are also conceivable.

[0011] Optionally, the measuring device location is designed for attaching a measuring device cassette.

[0012] A measuring device cassette is a container that contains the measuring device. In particular, the measuring device cassette can be removably attached to the measuring device location.

[0013] The advantage of the measuring device cassette is that the measuring device can be quickly and easily attached to the measuring device location and thus to the measuring device housing, and removed again if necessary. This simplifies the assembly, maintenance, and repair of a system comprising the measuring device housing and the measuring device.

[0014] The measuring device is designed to perform a measurement and provide the measurement result. The measuring device acquires information about the target object, particularly in a non-contact and non-destructive manner. The measuring device can acquire the information without mechanical interaction with the measuring area.

[0015] The measuring range of the measuring device is located in the vicinity of the measuring device housing. This means that, when the measuring device housing is attached to the means of transport, a projection of the measuring range in the direction of gravity ends at a maximum distance of 20 meters from a projection of the measuring device housing in the direction of gravity. The projection of the measuring range in the direction of gravity can end at a maximum distance of 10 meters from a projection of the measuring device housing in the direction of gravity. In particular, the projection of the measuring range in the direction of gravity ends at a maximum distance of 6 meters from a projection of the measuring device housing in the direction of gravity.

[0016] If the measuring range of the measuring device is arranged in the vicinity of the measuring device housing, then an influence of the measuring device by the means of transport can be reduced or eliminated if the device is mounted at a distance from the means of transport.

[0017] In particular, the measuring area is mainly located lower than the measuring device housing. This means: when the measuring device housing is attached to the means of transport, the measuring area is mainly located further down than the measuring device housing with respect to the direction of gravity. The measuring area can be located directly below the measuring device housing and / or offset from it. In this context, "mainly" means at least 50 percent of the volume of the measuring area. "Mainly" can mean at least 65 percent of the volume of the measuring area. In particular, "mainly" means at least 80 percent of the volume of the measuring area.

[0018] The measuring range can extend several meters into the ground. In particular, the measuring range extends to a maximum depth of 20 meters. For example, the measuring range extends to a maximum depth of 12 meters. The measuring range can extend to a maximum depth of 6 meters. "Extend deep into the ground" refers to a distance in the direction of gravity that begins at the ground, i.e., measured from a surface of the ground.

[0019] The measuring device housing comprises a measuring device location for a measuring device that uses electrical, magnetic, and / or electromagnetic radiation and / or fields to acquire information about the target object. For example, the measuring device can be a ground-penetrating radar, perform a magnetic field measurement, or perform an induction measurement. In particular, these three measuring methods can be combined in the measuring device housing according to the invention, the combination of which is described in the filed patent application with application number CH 001 023 / 2022.

[0020] In particular, the measuring device housing is designed such that, when in operational condition—i.e., equipped with a measuring device and attached to the vehicle—it is suitable for collecting information on explosive target objects in the ground. Explosive target objects can include mines, booby traps, explosives, demolition charges, cluster munitions, ammunition, and unexploded ordnance. However, improvised explosive devices (IEDs), such as those used by terrorist groups, can also be considered explosive objects.

[0021] A means of transport refers to a means that allows the measuring device housing, together with the measuring device, to be moved spatially. The means of transport can be a land vehicle. The means of transport can be a watercraft, for example, a floating means of transport such as a boat. The means of transport can be an air cushion boat. The means of transport is, for example, an aircraft. The means of transport can comprise wheels attached to the measuring device housing and a manipulation element such as a handle or a pulling element to allow the measuring device housing to be pulled or pushed by a living being. The means of transport can be unmanned or manned. The means of transport can be remote-controlled. The means of transport can also be autonomously controlled.

[0022] The ground-contact-free mounting is a force- and contact-locking connection between the measuring device housing and the means of transport. The mounting on the means of transport allows the measuring device housing to move with the means of transport, thus enabling measurements at various spatial positions. In particular, the measuring device housing is mounted outside the means of transport and at a distance from it.

[0023] The mounting is ground-free, meaning that the measuring device housing, which is attached to the vehicle, has no contact with the ground. This can be important for measurements involving explosive target objects. This minimizes the risk of such an object exploding.

[0024] The measuring device housing consists of at least 95 percent by weight of material other than ferromagnetic metal. This means that, if present, ferromagnetic metal makes up less than 5 percent of the weight of the measuring device housing. For example, the measuring device housing consists of at least 99 percent by weight of material other than ferromagnetic metal. In particular, the measuring device housing consists of at least 99.5 percent by weight of material other than ferromagnetic metal. The measuring device housing can also be completely free of ferromagnetic metal.

[0025] Optionally, the measuring device housing consists of at least 95 percent by weight of material other than metal. This means that, if present, metal makes up less than 5 percent of the weight of the measuring device housing. For example, the measuring device housing consists of at least 99 percent by weight of material other than metal. In particular, the measuring device housing consists of at least 99.5 percent by weight of material other than metal. The measuring device housing can also be completely free of metal.

[0026] In particular, the material of the measuring device housing, which is free of ferromagnetic metal, can comprise fiber composite material. Fiber composite material refers to a composite material comprising a base material and a reinforcing fiber embedded therein. Fiber composite material has the advantage of being both lightweight and mechanically stable.

[0027] In particular, the material of the measuring device housing, which is free of ferromagnetic metal, is known as GRP. GRP refers to fiberglass plastic or glass fiber reinforced plastic. GRP is a fiber composite material with corresponding advantages. Furthermore, GRP has the property of being non-conductive. This is advantageous when electromagnetic waves or fields need to pass through the material unhindered.

[0028] In particular, the material of the measuring device housing, which is free of ferromagnetic metal, is called CFRP. CFRP stands for carbon fiber reinforced plastic, or carbon fiber for short. CFRP is a fiber composite material with corresponding advantages. Furthermore, CFRP has the property of being electrically conductive to a certain extent. This is advantageous when electromagnetic waves or fields are to be shielded by the material.

[0029] In particular, the material of the measuring device housing, which is free of ferromagnetic metal, includes both GRP and CFRP.

[0030] For material of the measuring device housing which is free of metal, the same applies as described above for the material of the measuring device housing which is free of ferromagnetic metal.

[0031] The overload area of ​​the measuring device housing is a part of the measuring device housing that is movable relative to another part of the measuring device housing. The overload area can be moved from the normal position to the overload position and back. In the overload position, the overload area is at a greater distance from the contact point in the floor area than in its normal position. In other words, the overload area can move away from this contact point upon contact. Upon contact with the floor area, the overload area can therefore retreat from it.

[0032] Normal position means that the measuring device housing is in a ready-to-use operating configuration without contact with the ground, in which the measuring device carried by the measuring device housing is capable of performing measurements.

[0033] An overload path, which means a path of the overload area from the normal position to the overload position, can include a vertical component. Vertical means a direction parallel to the direction of gravity. Optionally, the overload path runs vertically. Optionally, the overload path is free of a vertical component. The overload path can include a horizontal component. Horizontal means a direction perpendicular to the direction of gravity. Optionally, the overload path is free of a horizontal component. Optionally, the overload path runs horizontally.

[0034] The overload area can undergo a translational movement from the normal position to the overload position and back.

[0035] Or the overload area can undergo a rotational movement from the normal position to the overload position and back.

[0036] In particular, the overload area can undergo a combined translational and rotational movement from the normal position to the overload position and back.

[0037] For example, the overload range can be moved from the normal position to the overload position and back by means of a coupling gear, in particular by means of a flat coupling gear.

[0038] The overload area can be moved from the normal position to the overload position and back using a parallelogram-like guide.

[0039] In particular, the overload area will be moved from the normal position to the overload position and back by rotation around a single axis.

[0040] Optionally, at least part of the measuring device location is located in the overload zone. In particular, a sensor area of ​​the measuring device location is located at least partially in the overload zone. The sensor area can also be located entirely in the overload zone.

[0041] Optionally, the overload area comprises a secondary plate which is movably and, in particular, tiltably attached to the rest of the overload area. At least part of the measuring device location can be arranged on the secondary plate. For example, a sensor area can be arranged on the secondary plate. The secondary plate can assume a measuring position in a rest position. The rest position is a spatial arrangement which gives the entire measuring device housing compact dimensions. In the measuring position, the secondary plate is in a spatial arrangement which is conducive to a measurement and, for example, provides components located on the secondary plate with distance from other parts of the measuring device housing and / or proximity to the floor area.

[0042] A movable auxiliary plate at the overload area allows the measuring device housing to be transported and / or stored with compact overall external dimensions, and allows the measuring device parts to be positioned in a favorable spatial arrangement during measurements.

[0043] The advantage of a measuring device housing made of material that is largely free of ferromagnetic metal is minimal interference from electromagnetic waves as well as electric and magnetic fields. Such material is largely transparent to electromagnetic waves and fields. This creates an environment at the measuring device location that has little or no effect on or interference with the measuring device's measurements.

[0044] The measuring device housing, which is largely free of ferromagnetic metal, can be lightweight. Designed largely free of ferromagnetic metal, the measuring device housing can be manufactured and used with low corrosion.

[0045] The measuring device housing protects the measuring device and allows it to be attached to the vehicle without contact with the ground. When the vehicle is moving, the overload zone ensures protection against mechanical overload caused by contact with the ground. The overload zone thus guarantees overload protection. Damage to or destruction of the measuring device housing, the measuring device, and / or the vehicle (or the attachment of the measuring device housing to it) can thus be prevented or significantly reduced. The movable overload zone allows the entire measuring device housing to be moved close to the ground with a low risk of damage, even while the vehicle is moving. This enables high-quality measurements from the measuring devices in the measuring device housing.

[0046] The overload protection allows the measuring device housing to serve as a stable support for attachment to the vehicle, which also offers protection against damage. At the same time, the overload zone, which recedes upon contact with the ground, allows the measuring device housing to be designed with a lightweight and simple shape, because a mechanical overload does not have to be absorbed by a complex structure and static properties of the measuring device housing. In other words, the measuring device housing with the overload zone can be designed to be less massive and less complicated, or less statically resistant, than measuring device housings without a movable overload zone. The overload protection thus allows the measuring device housing to be produced in a material-saving, cost-effective, and simple manner. Maintenance and repair are also simple and inexpensive in this way.

[0047] The overload range thus allows for the use of less material, and also of materials with less mechanical resistance. For example, thin walls are required, which in turn results in minimal interference with the measuring device's measurements. Materials can also be used that cause particularly minimal interference with the measuring device, even if this would not be used for reasons of mechanical stability in measuring device housings without a movable overload range.

[0048] The movable overload range allows the use of very little ferromagnetic metal and / or other metal in the measuring device housing without compromising the function of the measuring device housing, i.e. protection and support.

[0049] A combination of the two properties, on the one hand at least 95 weight percent material other than ferromagnetic metal and on the other hand the movable overload range, mutually reinforces its positive properties with regard to the low influence or interference of electromagnetic waves or fields.

[0050] Further preferred embodiments emerge from the dependent patent claims.

[0051] Optionally, the measuring device housing has an overload mechanism which enables controlled movement of the overload area from the normal position to the overload position and back.

[0052] A controlled movement is one whose trajectory and speed are determined by a specific selection of parameters. The controlled movement of the overload mechanism allows the measuring device housing to be specifically adjusted to different usage scenarios.

[0053] In particular, the overload mechanism is designed to independently move the overload zone from the overload position to the normal position. "Independent" means that the overload mechanism performs this movement back to the normal position automatically and does not require an external impulse. In other words, the overload mechanism controls this movement itself. In this case, the overload protection for the movement back to the normal position is independent of external control or regulation.

[0054] This has the advantage that the measuring device housing automatically returns to its normal position after the overload protection is activated, i.e., if the overload range moves from the normal position to the overload position. This simplifies operation and allows for efficient use of the measuring device.

[0055] For example, the overload mechanism is entirely mechanical, meaning it is free of electrical and electronic components.

[0056] In particular, this movement back to the normal position can be delayed compared to the movement out of the normal position. This can increase safety and prevent damage.

[0057] Alternatively, the measuring device housing can be designed free of an overload mechanism with an independent movement back to the normal position.

[0058] Alternatively, the measuring device housing may be free of an overload mechanism with a controlled movement back to the normal position.

[0059] Optionally, the overload mechanism is designed in such a way that it derives the entire energy required to move the overload area from the normal position toward the overload position from the contact of the overload area with the contact point in the base area. In other words, contact of the overload area with the contact point is sufficient to move the overload area from the normal position toward the overload position without the need for any additional energy supply from outside the measuring device housing. Thus, the movement from the normal position to the overload position is at least partially carried out by contact with the base area. In particular, this movement can be carried out all the way to the overload position.

[0060] By deriving all external energy required for this movement of the overload area from contact with the floor area, the measuring device housing is safe to operate and does not rely on external energy to at least partially perform the overload movement. This allows the at least partial overload movement to be carried out reliably. This also simplifies the use of the measuring device housing because no external power supply is required.

[0061] Alternatively, the overload mechanism may be supplied with external energy for at least part of the movement of the overload range from the normal position towards the overload position.

[0062] Optionally, the measuring device housing outside the overload area also comprises a fixed area, which is spatially positioned in the same way both in the normal position and in the overload position of the overload area, wherein the fixed area comprises a supporting fixed element, which is designed in such a way that when the fixed element is attached to the means of transport, the entire weight of the measuring device housing, including the measuring device space filled ready for use, is carried by the fixed element.

[0063] The fixed section is the part that maintains its position during overload movement. Within this fixed section, there is a fixed element that assumes a supporting structural function for the entire measuring device housing, including a load from the measuring device at the measuring device location.

[0064] The presence of such a fixed element has the advantage that a fastening device which attaches the measuring device housing to the means of transport can specifically engage this fixed element without the need for complicated suspensions or supporting structures.

[0065] In particular, the fixed element can extend from one end of the measuring device housing to an opposite end. In this way, the fixed element forms a kind of backbone. For example, this fixed element extends along a horizontal direction (i.e., perpendicular to the direction of gravity) from one end to the other when the measuring device housing is attached to the means of transport.

[0066] Alternatively, the measuring device housing can be designed free of a fixed element.

[0067] Optionally, the measuring device housing includes an anti-hook protection, which minimizes or prevents the measuring device housing from hooking or tilting when the measuring device housing comes into contact with the floor area.

[0068] Such anti-hook protection goes beyond simply rounding edges. The anti-hook protection, in particular, has a movable part. For example, the anti-hook protection has a rolling element that can rotate, thus preventing static friction between the measuring device housing and the floor area during the anti-hook protection.

[0069] The anti-hook protection has the advantage that the measuring device housing is less likely to tilt or catch when it comes into contact with the floor, thus remaining mobile and ready for use. Working with the measuring device housing during movement becomes easier, more efficient, and safer.

[0070] In particular, the hook-in protection is positioned in the overload area.

[0071] For example, the hook-in protection is designed as a roller. The roller is particularly capable of rotating around a primarily horizontally oriented axis (when mounted on the vehicle). For example, the roller has an outer tread made of carbon fiber reinforced plastic (CFRP), i.e., on the surface that comes into contact with the ground.

[0072] In particular, the hook-in protection can trigger the overload movement if a sufficiently large force is applied upon contact with the floor area.

[0073] Alternatively, the measuring device housing is designed without any hook-in protection.

[0074] Optionally, the measuring device housing is designed such that its fixed area can be non-positively connected to a fixed area of ​​a second measuring device housing in order to connect the two measuring device housings to form a functional unit.

[0075] In other words, two measuring device housings can be connected to each other at their respective fixed areas. This corresponds to a modular design, where one measuring device housing corresponds to one module, and one module can be connected to a second module.

[0076] The modular design allows two or more modules to be connected to form a functional unit. Connecting multiple modules results in a correspondingly larger total measuring range for all modules. This allows for flexible adaptation of the overall size of connected modules to specific conditions and / or requirements. Advantageously, this allows multiple measuring device housings to be moved using a single means of transport.

[0077] By using interconnected fixed areas, it may be sufficient to attach only one measuring device housing directly to the means of transport and to attach one or more additional measuring device housings to the means of transport via the measuring device housing already attached to the means of transport.

[0078] Individual measuring device housings can be easily and cost-effectively transported and stored due to their comparatively small size and low weight. At the same time, interconnected measuring device housings allow for a large overall measuring range to be utilized.

[0079] In particular, the overload zones of the two measuring device housings are functionally unconnected. This means that the overload zones of individual, interconnected measuring device housings function independently of each other. This allows each overload zone to react separately to contact with the floor area. This is an efficient, economical, and safe way to execute the overload movement. It also protects the material from unnecessary wear and tear by only performing the overload movement where indicated.

[0080] Alternatively, the overload areas of the two measuring device housings are functionally connected. Optionally, a fixed element can be force-fitted to a fixed element of the second measuring device housing to connect the two measuring device housings into a functional unit.

[0081] In other words, with the modular design, not only the respective fixed sections of the measuring device housings are connected to each other, but also their specific fixed elements. In this way, the backbone of one measuring device housing can be connected to the backbone of a second measuring device housing. This can be done quickly and efficiently. The fixed element can be easily located. With appropriate arrangement, the fixed element can be easily accessible. Connecting fixed elements can be done easily.

[0082] Alternatively, the measuring device housings are connected to each other without a force-locking connection of the fixed elements.

[0083] Optionally, the measuring device housing comprises a shielding housing, wherein walls of the shielding housing have a capability of at least partially shielding electromagnetic radiation.

[0084] In particular, the shielding housing has a low metal content. This means that the shielding housing has a metal thickness of a maximum of 1.5 millimeters and a minimum of 0.5 micrometers at the points relevant for electromagnetic shielding. The metal thickness can also be a maximum of 1 millimeter and a minimum of 1 micrometer. In particular, the metal thickness is a maximum of 0.5 millimeters and a minimum of 2 micrometers.

[0085] The low metal content allows for electromagnetic shielding, while at the same time, the measuring device housing can be designed with the corresponding advantages of a largely metal-free material. Optionally, the low metal content of the shielding housing includes non-ferromagnetic metal, particularly aluminum. This way, the magnetic field measurement method is not affected by the shielding housing. The metal content of the shielding housing can also include copper. Alternatively, stainless steel can also be included in the low metal content.

[0086] In particular, the small metal content can be applied to the shielding housing by vapor deposition.

[0087] Optionally, the shield housing is designed without metal.

[0088] In particular, the shielding housing is made of CFRP, which provides a shielding effect due to its slightly electrically conductive properties. The shielding housing can be made of CFRP.

[0089] The shielding housing can be located, in particular, near the measuring device location. For example, the shielding housing can at least partially enclose the measuring device location.

[0090] The shielding housing allows the measuring device to be shielded at the measuring device location from unwanted electromagnetic waves and / or fields from a specific direction. The shielding housing allows the measuring device to be shielded at the measuring device location, preventing unwanted electromagnetic waves and / or fields from being emitted or radiated in a specific direction.

[0091] The shielded housing can be designed for attachment to the measuring device location. A measuring device or, if applicable, a measuring device cassette can be arranged in the shielded housing. The shielded housing is particularly designed for attachment around the measuring device location. A measuring device or, if applicable, a measuring device cassette can be arranged at the measuring device location.

[0092] In particular, the shield housing and the measuring device housing are designed such that the shield housing can be detachably fastened to the measuring device housing.

[0093] Alternatively, the measuring device housing can be designed free of a shielding housing.

[0094] Optionally, the measuring device housing comprises a marking system which is designed in such a way that it is capable of marking a location of the floor area in a way that is recognizable to a human eye.

[0095] For example, the marking system is designed to apply paint to a floor area. The marking system can place an object such as a flag or a marker cone.

[0096] The advantage of the marking system, which marks a floor area recognizable to the human eye, is a simple and reliable identification of floor locations to which the measuring device housing has to draw people's attention based on information from the measuring device.

[0097] Alternatively, the measuring device housing is designed free of a marking system.

[0098] In particular, the measuring device housing is designed such that, in a transportable state, it has a maximum footprint of 120 cm by 80 cm. Transportable state means that the measuring device housing is in a spatial orientation and configuration in which it can be transported compactly and stably lying on a base. For example, with the auxiliary plate folded in (i.e., in the rest position).

[0099] With these dimensions, a measuring device housing fits on a standardized Euro pallet (EPAL1) and can therefore be easily transported and stored.

[0100] The subject matter of the invention is explained in more detail below using an exemplary embodiment, which is illustrated in the accompanying drawings. They show schematically:

[0114] Figure 10 shows the measuring device housing from Figure 1 attached to a means of transport without contact with the ground;

[0115] Figure 11 shows the measuring device housing from Figure 1 mounted on a rolling frame. In general, identical parts in the figures are provided with identical reference numerals. The designations left, right, bottom, and top refer to the drawing plane of the figures. For example, the numbering of the figure is at the bottom.

[0116] Figure 1 schematically depicts an embodiment of the measuring device housing 1 according to the invention in a perspective view. Parts of this measuring device housing 1 from Figure 1 are shown separately in Figures 2, 3, and 4 for better understanding. The measuring device housing 1 comprises an overload region 2, which is shown separately in Figure 4. The measuring device housing 1 also comprises a fixed region 3, which is shown separately in Figure 2. The measuring device housing 1 also comprises an overload mechanism 8, which is shown separately in Figure 3.

[0117] The upper part of the measuring device housing 1 is formed by the fixed area 3, which comprises, on the one hand, a fixed element 4 in the form of a hollow cylinder made of CFRP and, on the other hand, a hood-like cover from which the fixed element 4 protrudes on both sides. The hood-like cover is also made of CFRP and, among other things, offers protection against mechanical impacts from above and from the left, as well as from the sides where the fixed element 4 protrudes.

[0118] The fixed element 4 has an inner diameter on its right side protruding from the hood-like cover, which corresponds to the outer diameter of the fixed element 4 protruding on the left side of the hood-like cover. If two of these measuring device housings 1 are arranged next to one another, the fixed element 4 of the right measuring device housing 1 can be pushed into the fixed element 4 of the left measuring device housing 1. Furthermore, the measuring device housings 1 each have a recess around the fixed element 4 on their left side in the hood-like cover, which recess is large enough to accommodate the part of an adjacent fixed element 4 protruding beyond the hood-like cover.In this way, two of these measuring device housings 1 can be modularly connected to each other by connecting the respective fixed elements 4, so that the hood-like covers of the fixed area 3 directly adjoin each other. Such a connection is shown in Figure 9.

[0119] The fixed element 4 is designed as a supporting element for the entire measuring device housing 1 and the measuring device arranged thereon in the operational state (or, as in the present case, three measuring devices). As a result, a fastening device 21, which secures the measuring device housing 1 to a means of transport 20, can engage exclusively on this fixed element 4 and support the loaded measuring device housing 1 without contact with the ground. And, as already described, it is also possible to connect several measuring device housings 1 to one another via the fixed element 4.

[0120] The fixed element 4 is designed to be sufficiently stable to support several measuring device housings 1 connected via the respective fixed elements 4. These connected measuring device housings 1 can be connected to the means of transport 20 via the fastening device 21 only at the two outermost protruding parts of the fixed elements 4. Or the fastening device 21 engages only one or two of the fixed elements 4 of the connected measuring device housings 1 from above, through openings not shown in the figures arranged at the top in the hood-like cover of the fixed area 3, but nevertheless supports all of the interconnected measuring device housings 1 simultaneously. The fixed elements 4 form a backbone, so to speak, for all of the interconnected measuring device housings 1, to which the fastening device 21 can engage for ground-free attachment to the means of transport 20.The overload area 2 comprises a base plate, two attached side walls, and a tiltable auxiliary plate attached to the base plate. The base plate and the side walls are made of CFRP, while the auxiliary plate is made of GFRP. In the figures, a tilt axis or rotation axis of the auxiliary plate is indicated by a circle drawn on the side wall of the overload area 2. Two measuring device positions 5, 6 are arranged on the base plate of the overload area 2, and one measuring device position 7 is arranged on the auxiliary plate. Fastening elements, which are arranged at all measuring device positions 5, 6, 7 and serve to attach a measuring device cassette to the respective measuring device position 5, 6, 7, are not shown in the figures for the sake of simplicity. In all figures showing the auxiliary plate of the overload area 2, the auxiliary plate is arranged in the same spatial plane as the base plate of the overload area 2.This is the measuring position in an unfolded state, in which the measuring device location 7 is arranged in a ready-to-use position. However, it is also possible to fold the auxiliary plate upwards into a rest position (not shown). This allows for a space-saving arrangement of the measuring device housing 1 and also provides access to the measuring device location 7 from more sides. This facilitates transport, storage, operation, and maintenance of the measuring device housing 1.

[0121] A measuring device cassette comprising a measuring device for a magnetic field measurement method can be attached to measuring device location 5. A measuring device cassette comprising a measuring device for a ground-penetrating radar method can be attached to measuring device location 6. And a measuring device cassette comprising a measuring device for an electromagnetic measurement method can be attached to measuring device location 7.

[0122] An anti-hook device 9 is arranged at an end of the base plate of the overload area 2 opposite the secondary plate. The anti-hook device 9 is designed as a roller-like roll made of CFRP, which extends over the entire length of the overload area 2 and is rotatably attached to the base plate of the overload area 2. The anti-hook device 9 is arranged parallel to the fixed element 4 of the fixed area 3 and extends beyond the left and lower ends of the base plate of the overload area 3. In other words, the anti-hook device 9 protrudes to the left and downwards out of the overload area 3. This allows the anti-hook device 9 to be the first part of the measuring device housing 1 to come into contact with a floor area 23 or another obstacle with a very high probability when the measuring device housing 1 moves to the left.If such a contact occurs at a contact point 24, the round shape and the rotating mounting of the hook-in protection 9 can reduce the probability of the measuring device housing 1 hooking onto the ground or another obstacle.

[0123] The base plate of the overload area 3, when projected downwards, has approximately the same dimensions as the hood-like cover of the fixed area 3. The measuring device housing 1 is shown in Figure 1 with the overload area in its normal position. In the normal position shown, the measuring device housing 1 has a length of 120 cm (i.e., along a longitudinal axis of the fixed element 4) and a width of 120 cm (from the hook-in protection 9 to the end of the unfolded auxiliary plate of the overload area 2). When the auxiliary plate of the overload area 2 is folded up, the width of the measuring device housing 1 is only 80 cm. With these dimensions, a measuring device housing 1 fits on a standardized Euro pallet (EPAL1) and can therefore be easily transported and stored. The height of the measuring device housing 1 in the normal position is 120 cm.

[0124] The fixed area 3 and the overload area 2 of the measuring device housing 1 are connected to each other by the overload mechanism 8. The overload mechanism 8 guides the movement of the overload area 2 from its normal position to its overload position. The overload mechanism 8 is designed here in the form of a parallelogram-like guide. Two CFRP plates, shown in Figure 3, serve this purpose. This overload mechanism 8 thus comprises these two plates, which are arranged parallel to each other and are rotatably attached at opposite ends to the fixed area 3 on the one hand and to the overload area 2 on the other. This rotatable attachment is schematically represented in the figures by circles.

[0125] Figure 5 shows a side view of the measuring device housing 1 in its normal position. In the normal position, the overload zone 2 is located primarily beneath the fixed zone 3. The base plate of the overload zone 2 is located largely directly beneath the hood-like cover of the fixed zone 3. In the side view figures, i.e., Figures 5, 6, and 10, the direction of gravity runs from top to bottom.

[0126] Figure 6 shows the measuring device housing 1 in the overload position, also in a side view like Figure 5. It is clearly visible that, compared to the normal position in Figure 5, the overload area 2 in the overload position is shifted upwards to the right relative to the fixed area 3. In the overload position, the hook-in protection 9 has a spatial position shifted upwards to the right and thus distanced in this direction from a contact point 24 if the hook-in protection 9 were to come into contact with the contact point 24 in the normal position. The two parallel plates of the overload mechanism 8 move the overload area 2 in a parallelogram-like translational movement over an overload path with vertical and horizontal components.

[0127] Due to its parallelogram-like design, the overload mechanism 8 can execute a movement path along the overload path in a controlled manner. In addition, the overload mechanism 8 has a control component (not shown) which connects a plate of the overload mechanism 8 to the overload zone 2 and / or the fixed zone 3 (and / or connects overload zone 2 to the fixed zone 3). The control component defines which forces act on the fixed zone 3 and the overload zone 2 at which spatial position or position change. For example, a spring element or a gas pressure spring is arranged as a control component between the overload mechanism 8 and the overload zone 2 in such a way that the speed of the movement from the normal position to the overload position is controlled. In addition, the movement from the overload position back to the normal position is initiated independently, i.e. the normal position is automatically resumed.No external control is necessary for this.

[0128] Figure 7 shows an overload mechanism analogous to Figure 3, which also includes a shielding housing 10. The shielding housing 10 is mainly made of CFRP, which has an electromagnetic shielding effect due to its slightly electrically conductive properties. In addition, the CFRP can be vapor-deposited with a 2 micrometer thick layer of aluminum to reinforce the electromagnetic shielding where necessary. The shielding housing 10 extends over the entire length of the base plate of the overload area 2 and is located between the measuring device position 5 and the secondary plate with the measuring device position 7. The shielding housing 10 thus shields the middle measuring device position 6 from the left (measuring device position 5), right (measuring device position 7) and above. The measuring device position 6 is located within the shielding housing 10. The shielding housing 10 at least partially surrounds the measuring device position 6 and any measuring device cassette mounted thereon.The shield housing 10 is detachably attached to the overload area 3.

[0129] Figure 8 also shows the overload mechanism 2 analogous to Figure 3, this time comprising a marking system 11. The marking system 11 is designed here as a CFRP plate, which serves as a holder for a controlled ink reservoir (not shown here). The ink reservoir can release ink in a controlled manner through a round opening marked in the marking system 11, which falls downwards and to the right past the secondary plate of the overload area 2 with the measuring device location 7 and comes to rest at a specific point in the floor area. In this way, the specific point in the floor area can be marked in color so that a particular measurement result at this point can be clearly indicated with the naked eye.In the case of mine clearance, after the measurement by the measuring devices carried by the measuring device gel 1, the corresponding ground location can be marked in such a way that mine clearance personnel can identify this location in the ground area easily and quickly and without any additional aids.

[0130] Figure 9 shows two measuring device housings 1, similar to Figure 1, with force-locked fixed elements 4. The fixed elements 4 are pushed into each other and into the hood-like cover, as described above. Thus, two measuring device housings 1 are connected to each other like modules to form a functional unit. In this way, several modules, i.e., measuring device housings 1, can be connected to each other. Using 5 modules, for example, results in a total length of 6 meters.

[0131] Figure 10 shows a side view of the measuring device housing 1 fastened to the means of transport 20 without contact with the ground. The measuring device housing 1 is in a spatial position in which it can typically be oriented in use when fastened to the means of transport 20: arranged away from the means of transport 20. And arranged in front of the means of transport 20 in the direction of travel, since the direction of travel in Figure 10 is from right to left. In this way, a ground area 23 can be measured before the means of transport 20 travels over this ground area 23. In this way, information about a target object 22 located below the ground area 23 can be acquired without mechanically impacting the ground area 23.

[0132] The measuring device housing 1 is connected to the means of transport 20 via the fastening device 21. In Figure 10, the fastening device 21 engages the measuring device housing 1 laterally on both sides of the fixed elements 4. Figure 10 shows a situation in which the forward movement of the means of transport 20 causes the measuring device housing 1 to come into contact with the floor area 23 at a contact point 24 due to an uneven floor. In Figure 10, the measuring device housing 1 is in its normal position and, upon further forward movement of the means of transport 20, a mechanical force is exerted on the hook-in protection 9 via the contact point 24. This triggers an overload movement of the overload area 3 from its normal position to its overload position.

[0133] Figure 11 shows the same as Figure 10, but without the means of movement 20 and the fastening device 21. Instead, the measuring device housing 1 is fastened to a rolling frame 25. The rolling frame 25 is designed in two parts, with one part being fastened to each end of the fixed element 4 of the measuring device housing 1. Thus, a part of the rolling frame is fastened to each side of the measuring device housing 1. Wheels 26 are fastened to the lower ends of the rolling frame 25 and are arranged laterally offset from the measuring device housing 1 as viewed in the direction of movement (from right to left). In addition, both parts of the rolling frame 25 have a manipulation element in the form of a holding extension or an extension which extends away from the fixed element 4 to the right.On these holding extensions, the measuring device housing 1 together with the rolling frame 25 can be moved like a trailer, for example by a person or an animal, but of course also by vehicles of all kinds.

[0134] Such a combination of measuring device housing 1, rolling frame 25 with wheels 26 and human, animal or vehicle also falls under the designation measuring device housing 1 attached to a means of transport without contact with the ground within the scope of this invention.

[0135] The measuring device housing 1 can be moved with the rolling frame 25 in various ways, either by pushing, as in a movement from right to left, as shown in Figure 11, or conversely by pulling (i.e., a movement from left to right, whereby the measuring device housing 1 should be rotated 180 degrees so that the hook-in protection 9 is positioned at the front lower end of the measuring device housing 1 in the direction of movement). Pulling is recommended when mine clearance is not being carried out, but rather information on other target objects is to be collected.

[0136] A locomotion not shown here using a self-balancing single-axis drive (like a so-called Segway) is also envisaged. This could, for example, be designed similarly to Figure 11, wherein the rolling frame 25 is designed without any support extensions. Instead, a motor with a control system is provided, which drives the wheels 26 and, through appropriate control,

[0137] The measuring device housing 1, including all measuring devices, is balanced in a position free from ground contact and allows for desired movements. This variant also falls under the term "measuring device housing 1" attached to a means of transport without ground contact within the scope of this invention.
