Description

Transport vehicle with load securing system

Background of the Invention

The invention relates to a transport vehicle, in particular a truck, with a storage space for storing and transporting loads. The transport vehicle has a load securing system to prevent unauthorized access to the load or the transport vehicle itself.

The transport of goods and commodities by land places special demands on securing the load against unauthorized access. Especially when the transport vehicles are stationary, they are often the target of gangs specializing in theft of the load.

Conventional transport vehicles are therefore often equipped with an alarm system to thwart the theft of cargo. Such an alarm system is known, for example, from WO 2018/149458 A1 and has a functionally essential electrical alarm wire, which is arranged on a wall of the cargo space. In the event of intrusion into the hold - for example by breaking open a cargo hold door or by cutting open a tarpaulin - the electric alarm wire is interrupted and an alarm is triggered.

The problem is that the triggering of the alarm is preceded by damage to the transport vehicle when the alarm wire is broken - by breaking open the cargo hold door or by cutting open the tarpaulin. Even if the theft is foiled, the transport vehicle is damaged, which causes costs for repairs and unwanted downtimes.

object of the invention

It is therefore the object of the invention to provide a flexible and effective system for securing loads which prevents unauthorized access to the transport vehicle and its load before it is damaged.

Description of the invention

This object is achieved according to the invention by a transport vehicle with the characterizing features of patent claim 1 as mentioned at the outset. The dependent claims reflect preferred developments.

In other words, the object is achieved by a transport vehicle, in particular a truck, with storage space for storing and transporting cargo, having a load securing system for preventing unauthorized access to the load and/or the transport vehicle, characterized in that the load securing system has at least one has a rotating detector rotating an axis of rotation, wherein the rotating detector forms a detection area for determining a person and/or an object in the vicinity of the transport vehicle.

According to the invention, the transport vehicle is suitable for storing and transporting loads. In particular, the transport vehicle is intended for storing and transporting the load and, in relation to the space available for the transport of people, has a significantly larger, in particular much larger, storage space. This enables more economical use of the load securing system.

The storage space can be detachably and/or non-detachably arranged or formed on the transport vehicle.

A storage space designed to be detachable on the transport vehicle can, for example, but not exclusively, be designed in the form of a trailer or semi-trailer. Detachable storage space is usually formed on articulated lorries or trucks.

A storage space that is permanently arranged on the transport vehicle can be designed, for example, but not exclusively, in the form of a trunk or a platform. Permanent storage space is commonly provided on a van, van, or pick-up truck. In a special embodiment, the storage space can be designed as an operating material container on the transport vehicle that cannot be detached. In this way, theft of equipment can be prevented in an advantageous manner.

The transport vehicle may have combinations of detachable and non-detachable storage space, for example - but not exclusively - by attaching a trailer to a van. The storage space can form locally spaced partial storage spaces. A load securing system can advantageously be designed to secure the entire storage space, in particular all partial storage spaces.

The load securing system has at least one rotating detector rotating about an axis of rotation. The rotating detector is arranged or formed on the transport vehicle, in particular on a part of the transport vehicle that has the storage space. For example, the rotating detector can be arranged or formed on a towing vehicle or on a trailer of a semi-trailer truck that has the storage space. The position of the rotating detector on the transport vehicle can have use-related advantages, for example if part of the transport vehicle is to be replaced. In the above example, the arrangement of the rotating detector on the semi-trailer can prove to be advantageous in that during the transport or storage of the load, the uninterrupted load securing of the semi-trailer can also take place if the tractor is put to another use. If, on the other hand, the load securing is to be limited to the transport, an arrangement of the rotating detector on the tractor can be advantageous, since the load securing system can be adapted to a new trailer - which is coupled to the tractor - without additional installation work.

The rotating detector performs a predominantly unidirectional movement or a movement that rotates in only one direction. The direction of rotation can depend on the arrangement of the rotating detector on the transport vehicle. This allows the directions of rotation to be coordinated when using multiple rotating detectors. Provision can furthermore be made for the direction of rotation of the rotating detector to be changed as a function of an operating time and/or a number of revolutions. This can increase the durability of the rotating detector.

The rotating detector is designed to detect people and/or objects and has at least one acoustic and/or optical detection means. For example, but not exclusively, the rotating detector can have a camera, a measuring laser or an ultrasonic sensor. The detection means has a detection direction with a radiation angle relative to the axis of rotation of the rotating detector.

The rotating detector can have adjustment means for adjusting the emission angle of the detection means. The angle of radiation can be adjusted electronically and/or mechanically as well as automatically and/or manually. This allows the beam angle to be independent of the axis of rotation of the rotating detector and, for example, a tolerance-related tilt of the axis of rotation can be corrected.

The rotating detector can be arranged on the transport vehicle in a detachable, movable and/or non-detachable manner. This allows the rotating detector to be removed or folded down when the rotating detector is arranged at positions on the transport vehicle for which operation of the transport vehicle on the road is not permitted. Provision can furthermore be made for the rotating detector to be released or moved only when the load securing system is in the deactivated state. Advantageously, a manipulation attempt can thus be effectively prevented.

The detection area is formed by the rotating detector, in particular by the detection means rotating about the axis of rotation. The detection area can be formed in a planar or volume-like manner. For example, the detection area is planar, in particular as a plane, if the detection means is designed as a measuring laser and the angle of radiation of the detection means is constantly 90 degrees to the axis of rotation. Furthermore, for example, the detection area is formed in a planar manner if the detection means is formed as a measuring laser and the angle of radiation of the detection means is less than 90 degrees to the axis of rotation and is constant. In other words, the detection area in this example is designed as a conical surface. Furthermore, for example, the detection area can be designed volume-like if the angle of radiation is varied during the rotation of the rotating detector.

In a preferred embodiment of the transport vehicle, the rotating detector has a detection distance, the

Detection distance is designed to be variable or changeable by the load securing system. This allows for the restriction of

Detection area on the safety-related environment in particular and can avoid safety-uncritical detections of the rotating detector. In a preferred development, the detection distance is designed to be limited by the load securing system as a function of a rotational position of the rotating detector. In other words, the detection distance of the rotating detector varies during rotation. As a result, the environment to be monitored can be adapted, for example, as a function of the position of the rotating detector on the transport vehicle and/or to the lateral extent of the transport vehicle.

Also preferred is a development in which the maximum detection distance by the load securing system is limited to a maximum of 20 meters, in particular a maximum of 16 meters, particularly preferably a maximum of 12 meters.

In a preferred development, the detection area is limited to a side surface of the transport vehicle or the storage space of the transport vehicle by the load securing system in the manner of a contour. As a result, the accuracy for recognizing the people and/or objects intruding into the environment can be further improved.

An embodiment of the transport vehicle is preferred in which the rotating detector protrudes over a side surface of the transport vehicle and/or the storage space of the transport vehicle and forms an axis of rotation transversely, in particular at right angles, to the side surface. As a result, a side surface of the transport vehicle can be effectively monitored with only one rotating detector.

The load securing system can be designed to determine the dimensions of the part to be monitored, in particular the storage space, of the transport vehicle and to automatically adapt the detection area. For this purpose it can be provided that the load securing system scans the surroundings of the transport vehicle by changing the beam angle and automatically recognizes the transport vehicle to be monitored. This enables the load securing system to be installed particularly easily. Also preferred is an embodiment of the transport vehicle in which the rotating detector has a LIDAR (light detection and ranging) sensor. A LIDAR sensor is a particularly reliable and economical means of detection.

In a preferred embodiment, the rotating detector has a rotational speed of between 1 and 20 revolutions per second, in particular between 5 and 15 revolutions per second, particularly preferably between 8 and 12 revolutions per second. The rotation speeds can be adapted to the detection means. In principle, other rotation speeds are also conceivable, but in practice the specified rotation speeds represent a good compromise between durability, energy use and monitoring accuracy of the rotating detector. Provision can be made for the rotation speed to be variable during the rotation—both increasing and decreasing. As a result, the intensity of the monitoring or the accuracy of the detection means can be increased or reduced depending on the situation.

Also preferred is an embodiment of the transport vehicle in which the load securing system has at least one, in particular static, camera, with the camera being directed into the area surrounding the transport vehicle. The camera can have a pan range. Provision can be made for the camera to be activated only in the event of an alarm, for example by the vehicle driver and/or a monitoring center. A camera enables additional surveillance of the environment, in particular the surveillance of areas of the environment that are not covered by the rotating detector.

In a further development it is provided that the camera is aimed at the detection area of the rotating detector. This enables the redundant backup of the rotating detector as well as the transport vehicle. A transport vehicle with a camera represents an independent aspect of the invention and can occur in expedient combinations with the features set out in the description and the drawing.

An embodiment of the transport vehicle is particularly preferred in which the load securing system has at least one additional rotating detector for determining a person and/or an object in the vicinity of the transport vehicle.

In a preferred development of the transport vehicle, the rotating detector and the further rotating detector are arranged on opposite side surfaces of the transport vehicle. This enables particularly effective load securing by monitoring the endangered sides of the transport vehicle.

Also preferred is an embodiment in which the load securing system has at least one immovable sensor, in particular a reed sensor, for determining a person and/or an object in the vicinity of the transport vehicle. In a special embodiment, the reed sensor for monitoring is arranged at the rear of the transport vehicle. In this way, an effective comprehensive protection of the transport vehicle can be brought about.

An embodiment of the transport vehicle is particularly preferred in which the load securing system has a sensor for monitoring the air quality, in particular a gas sensor, inside the transport vehicle. As a result, an undesirable change in the air quality, in particular due to external influences, can be recognized in good time and the driver of the vehicle can be warned.

A transport vehicle with a sensor for monitoring the air quality inside the transport vehicle represents an independent aspect of the invention tion and can occur in appropriate combinations with the features listed in the description and the drawing.

In a preferred embodiment, the load securing system has an alarm system, the alarm system being actuated by the load securing system when people and/or objects are detected and/or when the air quality changes. The alarm system can have optical and/or acoustic alarm means to draw attention to the transport vehicle. Furthermore, it can be provided that the alarm system informs a monitoring center or the authorities about the intrusion. This serves to effectively deter intruding persons and/or objects.

The use of a rotating detector, in particular a LIDAR detector, for securing loads on a transport vehicle represents an independent aspect of the invention and can occur in appropriate combinations with the features set out in the description and the drawing.

Further advantages of the invention result from the description and the drawing. According to the invention, the features mentioned above and those detailed below can each be used individually or collectively in expedient combinations. The embodiments shown and described are not to be understood as an exhaustive list, but rather have an exemplary character for the description of the invention.

Detailed description of the invention and drawings

1 shows an embodiment of a transport vehicle according to the invention in a side view;

FIG. 2 shows the embodiment of the transport vehicle from FIG. 1 in a plan view; FIG. 3 shows the embodiment of the transport vehicle from FIG. 1 with a schematic representation of the mode of operation of the load securing system.

Fig. 1 shows the side view of a transport vehicle 10 in a special embodiment as a semi-trailer truck with a tractor 12 and a trailer 14. The transport vehicle 10 has a storage space 16 for storing and/or transporting cargo (not shown), for example goods, goods and/or animals up. According to the embodiment shown, the transport vehicle 10 is designed to be separable between the tractor 12 and the trailer 14 . In other words, the storage space 16 is detachable from the rest of the transport vehicle 10 . In addition, the storage space 16 can also be detachably arranged in the form of a trailer. However, it is also conceivable that the transport vehicle 10 is inseparable, for example in the form of a “one-piece” truck, a transporter or a delivery van.

The storage space 16 and the cargo in the transport vehicle 10 are secured according to the view shown on a side face 18 of the transport vehicle 10 by a tarpaulin 20, which makes it difficult to look into the storage space 16 and to gain unauthorized access to the cargo.

A rotating detector 22 is arranged on the trailer 14 below the storage space 16 . By locating the rotating detector 22 on the trailer 14, the storage space 16 can be monitored even when the tractor 12 is separated from the trailer 14. This makes it possible, for example, to protect the load when the semi-trailer 14 is parked in a parking space. However, provision can also be made for the rotating detector 22 to be arranged on the tractor 12 . In this way, the semi-trailer 14 or the storage space 16 can be secured while the tractor 12 is coupled to the semi-trailer 14 . This is of particular advantage for freight forwarders who only provide a tractor 12 for transporting the load and who are supposed to ensure appropriate security. 2 shows a plan view of the transport vehicle 12 to clarify the arrangement of the rotating detector 22. The transport vehicle 10 has a further rotating detector 22 which is arranged on a side face 18 opposite the first rotating detector 22 on the trailer. Both rotating detectors 22 each have an axis of rotation 24 . The axes of rotation 24 are formed transversely, in particular at right angles, to the respective side surfaces 18 of the transport vehicle 10 or the trailer 14 . As a result, the correction-free rotational movement of the rotating detectors 22 is favored.

According to the embodiment, the rotating detectors 22 each have a LIDAR detection means with at least one measuring laser 26 (only one measuring laser 26 is shown for reasons of clarity). The measuring laser 26 is emitted from the rotating detector 22 at an emission angle 28 from the axis of rotation 24 . The measuring laser 26 rotates around the axis of rotation 24 of the respective rotating detector 22 and forms a cone 30 with a cone angle 32 . According to the embodiment shown, the cone 30 is formed with a cone angle 32 of less than 180° pointing away from the respective side surface 18 . As a result, a deviation of the axis of rotation 24 from the ideal position can be corrected in a simple manner. The cone angle 32 is preferably approximately, in particular exactly, 180°, as a result of which a plane parallel to the side face 18 is formed. A so-called blind spot of the rotating detector 22 between the side surface 18 and the measuring laser 26 can thereby be effectively prevented. However, it is generally also conceivable to form a cone 30 with a cone angle 32 of more than 180°, as a result of which the cone 30 opens towards the respective side face 18 . If necessary, this makes it possible to monitor only a partial area of the side surface 18 .

The rotating detectors 22 have adjustment means (not shown) which are designed to adjust the emission angle 28 of the measuring laser 26 while the rotating detector 22 is rotating. In other words, the emission angle 28 can be changed or varied as a function of a rotational position 34 (see FIG. 3) of the rotating detector 22 . So it can be Change the cone angle 32 of the rotating detector 22 during the rotation—for example—to a cone angle 32'. It is thus advantageously possible to react flexibly to the configuration of the transport vehicle 10 - for example bulges in the tarpaulin 20 - and/or obstacles - for example trees - in the surroundings 34 of the transport vehicle 10, which would lead to a blockage of the measuring laser 26. Furthermore, a manipulation or bypassing of the measuring laser 26 can be effectively prevented by a—for example—accidental variation of the cone angle 30 .

In the monitoring state, the rotating detectors 22 protrude at least partially beyond the respective side surfaces 18 in order to enable the measuring lasers 26 to emit unhindered. During operation of the transport vehicle 10, the rotating detectors 22 can be configured to be pushed back behind the lateral extension of the trailer 14 in order not to increase the overall width of the transport vehicle 10 unnecessarily. Provision can also be made for the rotating detectors 22 to be swiveled under the trailer 14 and/or for the rotating detectors 22 to be secured by detaching them from the transport vehicle 10 at a storage location provided for this purpose. If the rotating detectors 22 are arranged at locations on the transport vehicle 10 that do not endanger traffic safety or the general operating license of the transport vehicle 10, it can of course be provided that the rotating detectors 22 remain on the transport vehicle 10 in the monitoring state during operation of the transport vehicle 10.

The towing vehicle 12 has two laterally arranged, in particular static, cameras 36 for monitoring the surroundings 34 of the transport vehicle 10 . The cameras 36 are arranged on opposite sides of the transport vehicle 10 and are mainly directed against the direction of travel of the transport vehicle 10 in the environment 34 of the transport vehicle 10 or the storage space 16 . This promotes overall image monitoring of storage space 16 . Fig. 3 shows the side view of the transport vehicle 10 and illustrates the functionality of the load securing system in the - exemplary - monitoring of the trailer 14 or the storage space 16.

The rotating detector 22 has a detection radius 38 that extends beyond the maximum extension of the transport vehicle 10, starting from the position of the rotating detector 22 on the transport vehicle 10, in all detection directions. The detection radius 38 represents the practically possible range of the measuring laser 26 of the rotating detector 22 . In the example shown, the detection radius 38 is blocked by a footprint 40 of the transport vehicle 10 .

The detection radius 38 or the practically possible range of the measuring laser 26 is limited to a detection distance 44 depending on a rotational position 42 of the rotating detector 22 . The rotational position 42 relates to a reference 46 which, according to the embodiment shown, is designed as a horizontal reference straight line originating in the rotating detector 22 for illustrative purposes. However, the function of the load securing system only requires a clear assignment of the rotational position 42 to a reference 46, which can also be formed by a calibrated zero position of the rotating detector 22, for example.

The load securing system forms a detection area 48 by assigning a detection distance 44 to each rotational position 42 of the rotating detector 22 . In the embodiment shown, the detection area 48 includes the trailer 14 and part of the tractor 12 and extends in the vertical direction from the top of the transport vehicle 10 to the contact area 40. The detection area 48 can, however, be partially or completely expanded within the detection radius 38 and/or be reduced.

The intrusion of a person and/or an object into the detection area 48 can be recognized by the load securing system as an unauthorized approach the transport vehicle 10 or the storage space 16 can be recognized. The intrusion can then be reported to the vehicle driver or a monitoring center and appropriate preventive measures can be taken before the transport vehicle 10 is damaged. Alternatively or additionally, it can be provided that an alarm system is triggered when the detection area 48 is invaded.

The camera 36 is directed into or onto the detection area 48 and the surroundings 34 of the transport vehicle 10 in order to visually check the intrusion into the detection area 48 . This allows additional information about the reason or the number of intruders to be obtained. This enables the transport vehicle 10 or parts of the transport vehicle 10 to be secured even more effectively against unauthorized access.

To monitor the quality of the air, the load securing system has a gas sensor (not shown) arranged in the interior 50 of the transport vehicle 10 or tractor 12 . The gas sensor analyzes the air in the interior and warns of unwanted and/or induced hypnotic compositions. As a result, the driver of the vehicle can be prevented from being forced to sleep due to external influences and subsequent access to the load can be prevented.

Taking all the figures of the drawing together, the invention relates to a monitoring system for a loading space 16 of a truck 10 with a laser measuring beam 26, which, rotating about an axis of rotation 24 running transversely to the direction of extension of the laser measuring beam 26, covers a monitoring area 48 for detecting persons intruding into the monitoring area 48 and/or objects. reference list
