Modular fastening system

The present invention relates to a modular fastening system Be for attachment of electronic Schaltun gene and in particular to a modular fastening system for telematics units to containers.

The term "telematics" is understood to mean, in particular, a technology which is used in the field of security technology, fleet management, logistics and the long-distance and, in particular, links telecommunication and computer science. Telematic units can, for example, have a location determination unit and a telecommunication unit for transmitting the acquired location data to a computing unit or data processing unit present in a communication network.

For the worldwide transport of semi-finished and finished products, existing steel containers are common. The containers have on one end closable doors, which can also be particularly secured. The walls of the containers are usually profiled to stabilize trapezoidal shape. For ship transport, the Contai ner stackable, the stacks are locked together. In rail and truck transport, individual containers are loaded. To control the Materialflus ses of semi-finished and finished products, it is necessary to be able to follow the transport route and the respective location of the container. Valuable container contents must also be monitored to prevent theft or tampering.

Usually, these transport containers are therefore provided with mobi len telematics units, which a tracking and Implement monitoring function. In this case, for example, a current position of the transport container equipped with the telematics unit can be detected by means of a mobile radio interface module and a GPS module and transmitted to a central data processing unit. Furthermore, the telematics unit can have sensors which capture status data of the transport container or its contents, wherein the status data can be stored locally in a data memory and / or transmitted to the central data processing unit. Furthermore, an evaluation module for evaluating the data he captured can be provided in the telematics unit. To operate the various electronic circuit modules, the telematics unit further has a power supply unit, which is implemented or supplemented for example by a battery, a battery mulator or a solar panel.

Such telematics units can thus have a variety of different circuit modules, which must be combined differently depending on the application and attached to the transport container.

From the publication WO 2011/018282 Al a Aufnahmevor direction for a modular telematics unit is known, in a retaining rail at least one housing for the Schaltungsmo modules and a solar panel can be inserted. An extension of the telematics unit is therefore possible only in the direction of the retaining rail.

Furthermore, from the document WO 2013/170851 Al a modula res housing system for a telematics unit is known, which has increased flexibility while improved ro bustheit. The disclosure of this document is hereby added by reference to the present invention.

From the document US 7 339 482 B2 a Telema tikeinheit is also known, wherein an electronic circuit in the neren of a container is attached. To realize an RF interface, an antenna is led to the outside via ventilation openings of the container.

Furthermore, from the publication WO 2010/133980 Al a Te lematikeinheit known, wherein an electronic circuit is mounted on the outer wall of a container under a ventilation hood and sensors are performed through the ventilation openings in the container to a monitoring of the container container interior realize.

Due to the division of the electronic circuit into an internal circuit part, e.g. arranging sensors within the container, and into an external scarf processing part, e.g. arranging the antenna outside the container, flexibility and robustness in the attachment is severely limited. On the one hand, for example, an exchange and / or maintenance of the telematics unit is time-consuming and expensive. On the other hand, a robustness against environmental influences (water, wind, humidity, temperature, etc.) is only insufficiently guaranteed.

The invention is therefore based on the object, a modular fastening system for fastening an electronic

Circuit module, in particular a telematics unit, to create, which allows a high degree of flexibility and robustness compared to environmental influences a simplified replacement of the telematics unit.

According to the invention this object is achieved by the features of Pa tentanspruchs 1.

In particular, by the use of a base module with at least one hidden air duct, wherein the air duct allows indirect guidance of an air flow from the housing opening to the at least one air sensor opening of a circuit module, an air condition (eg air pressure, air temperature) can be achieved. door, humidity, smoke particles, gas components) are sensory detected in a Contai ner, however, the corre sponding sensors for this purpose in an easily replaceable and protected against environmental influences circuit module (All-in-One) on the outer wall of the container.

Preferably, the hidden air duct can be designed in a meandering shape, resulting in a mechanical robustness in particular against unwanted ingress of water and

Dust particles in the circuit module further improved.

For example, the circuit module further comprises a light sensor opening, wherein the base module further comprises a straight light channel, which allows direct guidance of a light beam from the housing opening to at least one light sensor opening. As a result, monitoring of the interior of a container based on brightness or wavelength of detected light rays (e.g., infrared, UV and / or visible light) can be easily performed. Furthermore, sensors based on light or radar may perform measurements through the light channel to the outside, e.g. Distance measurements (container full / empty).

Preferably, the air sensor opening has a wasserundurch permeable membrane which is permeable to smoke particles and / or gases. As a result, the circuit module can be insbesonde re protected against unwanted ingress of water and / or dust particles, while a reli casual detection of an air condition in the container is still guaranteed.

Furthermore, the base module in the air duct may comprise at least one filter which is permeable only to certain smoke particles and / or for certain gases. In this case, by simply replacing different Sockelmo modules, each with different filter characteristics one integrated in the circuit module integrated sensors are adapted to different applications.

For example, the light sensor opening may have a window which is transparent to light but impermeable to water and air. In this way, the robustness of the circuit module against environmental influences can be further improved. For example, the window in the circuit module may be made of opaque (i.e., translucent but opaque) plastic.

Furthermore, the base module can also have at least one filter in the light channel, which is permeable only for specific wavelengths. Again, by simply replacing different base modules, each with different filter characteristics built in a circuit module unit Liche sensors to a variety of applications will be fit.

Further, the mounting module may have a perforated hole opening, which is net angeord over the at least one housing opening, and the base module may have at least one hole field for receiving securing screws. As a result, the base module can be easily secured against theft with the container door closed. Furthermore, the sound module can be secured against theft either if it is integrally connected either by continuous connecting elements, or the base module is integrally formed with the circuit module and thus permanently attached thereto.

Preferably, in the circuit module in the region of the sensor openings, a sensor chamber may be formed with a plurality of sensors. In addition to the already mentioned air and

Light sensors can also be used, in particular, acceleration sensors, rotation sensors and magnetosensors for detecting a condition of a container. Finally, a solar module may further be provided which has at least one solar cell. The life or battery life of the circuit module can be improved ver or even allow a permanently maintenance-free loading operation.

Furthermore, the fastening module may have a slide which is displaceable for opening / closing the at least one air duct opening. This can be opened and closed in a simple manner, the system's flexibility, especially at the time tapped circuit module, the Belüftungsöffnun conditions of the container.

In the further subclaims further advantageous embodiments of the invention are characterized.

The invention will be described below with reference to Ausführungsbeispie sources with reference to the drawings.

In particular, the present invention comprises a modular fastening system for telematics units, the individual modules of which can be linked to one another in the manner of a modular system in a simple and flexible manner. For example, such a system can be configured as known from document WO 2013/170851 A1, the disclosure content of which is added by reference to this application.

The fastening system can be attached to the outside, for example, on the top, on the side walls or on the doors of a so-called transport container. Preferably, it allows the fastening system a modular extension or stacking in the groove-shaped depressions or beads of a transport container or a so-called Wechselbrü bridge, on the ventilation openings of the container. Of course, openings can also be provided specially or the fastening system can also be used without the presence of depressions.

Figure 1 shows a simplified perspective Teilan view of a side wall 1 of a housing and in particular egg nes conventional transport container. The container usually has a plurality of ventilation openings 2 in front of certain locations of the side wall 1. A ventilation hood 22 arranged above the ventilation openings 2 protects Licherweise the container against unwanted water entry and allows ventilation of the container interior. The ventilation hood 22 is usually fastened with Befestigungsele elements 21 on the container side wall 1.

The present invention takes advantage of the presence of these vents 2 in containers and preferably arranges the fastening system according to the invention directly above the vents 2. Of course, additional openings at any point of a container or a housing wall 1 can be provided.

2 shows a simplified exploded view of the fastening system according to an embodiment of the invention. For example, a mounting module 3 immedi applicable attached to the housing wall 1 of a container who the. For example, the attachment module 3 can be configured in the form of a click mount. The attachment of the Be fastening module 3 can be done for example via the four lugs 3d by riveting. Alternatively, the Befestigungsmo module with the housing wall 1 also welded, screwed, glued ver or otherwise firmly connected.

The fastening module 3 has an air duct opening 3a, which is located above at least one housing opening 2. Before preferably the existing ventilation openings of containers are used as a housing opening. At the Untersei te of the mounting module 3, a slide 3c may further be formed from, via a slot 3e for opening and

Closing the air duct opening 3a can be moved manually. Furthermore, the mounting module 3 housing openings in the region of Ge 2 have a hole field opening 3b, which allows securing of the fastening system against theft by Si cherungsschrauben S.

According to Figure 2, a Sockelmo module 4 is releasably connected to the mounting module 3. In the case of those described above Klickhalterung the socket module 4, for example via not presented Darge spring elements in frontally formed Aussparun conditions of the mounting module 3 are clicked.

The base module 4 may for example be designed as a spacer to the bottom of the trapezoidal recess to ei NEM subsequent ensuing module 5, which has a greater width than the base module 4, ensure a tight fit and sufficient distance from the housing wall 1.

The base module 4 also serves to form a hood th air channel 4a, on the one hand allows detection of the air flowing from the container and on the other hand, a protection in particular against unwanted water entry made light. Furthermore, the base module can have a straight light channel 4b, which allows direct guidance of a light beam from the container to the circuit module 5. Furthermore, the base module may have a perforated box 4c, which in conjunction with the hole field opening 3b and the fuse screw S an anti-theft of the overall system made light. In the event that the mounting module 3 has the slide over 3c, the socket module may further comprise a groove 4d in which a guide pin of the slider 3c can run.

In particular, the base module 4 further (not presented Darge) have filters in the air duct 4a and / or

Light channel 4b can be arranged. In the light channel 4b, for example, wavelength filters for certain wavelengths (infrared, ultraviolet or visible light) may be arranged. For example, filters for specific gases or particle sizes may be arranged in the air channel 4a. In this way, with only a standard circuit module (all-in-one) 5 and by replacing terelementen equipped with different Fil filament modules 4 an adaptation of the sensor to the most diverse requirements can be realized. According to Figure 2, the actual circuit module 5 or the telematics unit attached to the base module 4 who the. In the telematics unit, a variety of elec tronic circuits can be arranged. This can, for example, an accumulator or a battery for Energieversor supply, a GPS module (Global Positioning System) for recording location data, sensors for detecting status data of the transport container, its contents or the housing system, an evaluation unit for evaluating the collected data and / or a radio module, such as a GSM module for connection to a central data processing unit via, for example, a mobile network. Furthermore, any further electronic circuits can be realized on circuit boards, which can be arranged in the circuit module 5.

In this case, the circuit module 5 preferably has a sensor chamber 5S in the region of the air channel 4a and / or the light channel 4b, which may have a large number of sensors. In this case, air sensors can detect the constituents of the components supplied in particular via the air duct 4a, in particular of the gases and smoke particles. The air sensors can continue to detect a humidity, an air temperature and an air pressure of the container via the air duct 4a supplied air. For example, light sensors can detect the light received via the straight light channel 4b. In particular, the light sensors used may also be IR, UV, visible or radar based sensors which emit electromagnetic radiation through the light channel to the outside (i.e., into the container interior) and from the reflected rays, e.g. Distance measurements allow (e.g., container full / empty). In addition to the air and

In particular, light sensors may also be formed of acceleration sensors, rotation sensors and magnetosensors in the circuit module and in particular in the closed sensor chamber 5S. Furthermore, (not shown) proximity sensors in

Circuit module be formed. Such proximity sensors may include, for example, ultrasonic sensors, optical sensors, capacitive sensors and / or magnetic sensors, which are arranged in the circuit module 5 such that they detect a removal of the circuit module 5 from the ground. In this way, e.g. an alarm is triggered and transmitted to the central data processing unit, e.g. an unauthorized removal (theft) of the Schaltungsmo module 5 and the associated fastening system signali Siert.

As a material for the base module 4 and the circuit module 5, for example, a mechanically high-strength and temperature-resistant plastic can be used, which is also ge compared to sunlight stable. This can ensure that the modules reliably withstand the most diverse environmental influences.

Preferably, the base module 4 can be integrally formed with the circuit module 5, whereby a mechanical fuse on the locking screws S for the scarf processing module can be realized. In the same way that can

Circuit module 5 also firmly screwed to the base module, glued or otherwise connected, which can be if a mechanical anti-theft device for the circuit module just realized.

Further, according to Figure 2, a solar module 6 may be attached to a solar cell 6a as a planar electronic component to support a power supply for the electronic circuits in the circuit module 5 and / or to charge a battery.

As shown in FIG. 2, the individual modules can furthermore be connected to the fastening element 3 with connecting elements V. FIG. 3 shows a simplified sectional view of the fastening system according to FIG. 2 in an assembled state. He invention according to the fastening system can use the existing ventilation openings 2 of a container to reduction in a simple manner the interior of the container, for example its air ogether _Z and to detect lighting conditions, or to be monitored chen.

According to FIG. 3, the fastening module 3 can be mounted above the ventilation openings 2 such that its air channel opening 3a lies over at least one of the ventilation openings 2. In order to obtain a desired tightness of the system, for example, a sealing ring 10 made of elastic material is provided on the underside of the fastening module 3, which surrounds at least the air duct opening. According to Figure 3, the sealing ring 10 in addition to the hole field opening 3b surrounded. Furthermore, on the side of the mounting module 3 a Dichtmas se 11 are formed, which further increases an air and Wasserdich activity between the housing wall 1 and mounting module 3. The attachment module 3 or the click mount can be flexibly grouted or glued ver by means of industrial adhesive. The space between the mounting module 3 to the housing openings 2 can be reliably waterproof and impermeable air sealed.

For the realization of the hidden air channel 4a, a cavity is formed in the base module 4, which extends from the housing opening 2 and the air duct opening 3a to an air sensor opening 5a of the circuit module 5. The air duct opening 3a and the air sensor opening 5a are in this case arranged offset from one another, resulting in the at least partially hidden and tortuous air duct 4a, in which an air flow 7 from the container interior through the hous seöffnung 2 to the air sensor opening 5a can flow, which is located in the region of the sensor chamber 5S. The Luftka signal 4a can completely in the base module 4 or together with the surface of the mounting module 3 may be formed. Further, the air channel 4a may have one or more loops (not shown).

The circuit module 5, which in turn preferably is air-tight and which is attached in a watertight manner to the base module, has at its air sensor opening 5a, for example, a water-impermeable membrane 5aa which is permeable to smoke particles and / or gases. For example, the membrane is a wasserun permeable semi-permeable membrane, which is permeable to solids up to a diameter of about 10ym. As a result, for example, smoke and fine dust particles can be detected, while larger dirt particles are reliably prevented from penetrating into the circuit module. The membrane may be a woven or a non-woven membrane, with non-woven membranes being preferred because of their path structure.

Behind (in the direction of air flow) of the membrane 5aa, for example, one or more of the air sensors S1 in the sensor chamber 5S may be arranged to e.g. respective gas fractions, smoke particles, dust particles, humidity, air pressure, air temperature, etc. to capture. According to the invention, it is possible to monitor only the air of the container interior, although the circuit module is placed outside the container is. Outdoor environment conditions can thus be reliably excluded. The air sensors S1 can also be separated, for example by an additional air and water-tight wall (shown in phantom) from the other sensors ge.

Similarly, for the realization of the straight Lichtka nals 4 b in the base module 4, a cavity may be formed, which extends from the housing opening 2 and the air duct opening 3 a to a light sensor opening 5 b of the circuit module 5. The air channel opening 3a and the light sensor opening 5b are arranged such that the straight light channel 4b, in which a light beam 8 can only flow out of the container interior through the housing opening 2 as far as the light sensor opening 5b, which in turn is located in the region of the sensor chamber 5S.

The circuit module 5 mounted on the base module has at its light sensor opening 5b, for example, a water and air impermeable window 5bb, which is transparent to light. Behind the window, one or more light sensors S2 can be arranged in the sensor chamber 5S. The light sensors S2 used may be passive sensors but they may in particular also be active sensors which are based on IR, UV, visible light or radar electromagnetic electromagnetic radiation through the light channel 4b to the outside (ie into the container interior). send out (not shown) and based on the reflected rays, eg Allow distance measurements (e.g., container full / empty). For example, window 5bb may be made of opaque plastic which is translucent but opaque.

In this way, a completely against Umwelteinflüs sen completed circuit module 5 can be connected in a particularly simple and very reliable way to detect a container interior condition.

Finally, the attachment system may still have a solar module 6 that is mechanically and electrically connected to the sound module 5, and represents an additional source of energy to the batteries or accumulators (not shown).

As already described above, both the air channel 4a and the light channel 4b have a plurality of filters within the base module 4, whereby the sensor characteristics of the circuit module 5 can be adapted to the most diverse applications. The manufacturing costs for the circuit module 5 can thereby be substantially reduced, since it is configurable via the socket module 4.

Although the base module 4 has been described as a self-contained module, it may also be integrated into the circuit module 5 and, as it were, integrally formed with the housing of the circuit module. In this case eliminates the need for a seal between the circuit module and socket module.

Furthermore, this results in a particularly simple theft protection. According to Figure 3, the base module 4 further comprises a hole field 4c with a plurality of holes and the mounting module 3 have an associated hole field opening 3b. The holes of the hole 4c are preferably smaller in diameter than the housing openings 2, whereby a suitable securing screw S can be screwed through the housing opening 2 into one of the holes of the hole field 4c without any fine adjustment, whereby socket module 4 (and circuit module 5) can be screwed. can be secured against theft in a particularly simple manner.

Figures 4 and 5 show simplified perspective

Since preferably the attachment module 3 permanently remains on the container can by the slide 3 c the ventilation openings 2 simply opened or closed who the. In this way, a wide variety of applications can be realized.

Accordingly, the slide 3c, the recess in which the slider 3c runs, the air channel opening 3a and the hole field opening 3b are preferably surrounded by the sealing ring 10. FIG. 8 shows a simplified perspective view of a base module according to an embodiment of the invention. According to FIG. 8, the base module 4 can also have a sealing ring 10 on its lower side, which allows an air-tight and watertight connection of the fastening module 3 with the base module 4. Accordingly, the air channel 4 a, the light channel 4 b, the perforated field 4 c and the groove 4 d are preferably surrounded by a further sealing ring 10. The same applies to the attachment of circuit module 5 on Sockelmo module 4 if they are formed in two pieces.

FIG. 9 shows a simplified exploded view of the fastening module 3 with a cover module 9 according to an exemplary embodiment of the invention. According to the invention, a cover module 9 can thus also be plugged or clicked directly onto the fastening module 3.
