Description

The invention relates to a device for recording and transmitting measurement data for at least one measured variable. The device comprises a measuring module for recording the measured data, a memory for storing the measured data, a transmission module for transmitting the measured data and an activation element for activating and / or deactivating a transmission process for the measured data by means of the transmission module, the measuring module, the memory, the Transmission module and the activation element of an electronics for controlling recording and transmission of the measured data are assigned.

The invention further relates to a method for recording and transmitting measurement data of a measured variable, in which such a device is used.

More and more frequently in the transport and logistics sector, the demand is made that a predetermined measured variable is to be monitored during the transport of goods to be shipped. This requirement is often necessary to ensure the quality and shelf life of products such as medicines and food during transport and to allow for appropriate use of the products after transport. Examples of measured variables to be monitored are temperature, pressure, humidity or incidence of light. These measured variables are usually recorded during the entire transport and then read out.

In order to monitor such measured variables during the transport of a shipment, transport containers can comprise integrated sensor modules with a device for recording measured data of a measured variable. However, it is also possible to use mobile sensor modules, which are inserted, for example, in addition to the transported goods to be transported in a transport container or in a transport packaging.

During transport, the measured data is recorded continuously or interval-controlled according to a sampling rate of the sensor modules. The reading of the measured data recorded then takes place, for example, via a connection of the sensor module with a reader by USB connection (Universal Serial Bus) and / or via a non-contact interface for reading data, for example by means of RFID technology, for which the mobile sensor module previously simply from the Transport container is removed. The read-out measurement data are processed after readout, for example stored on a server, where they are available for further processing. However, such solutions require that the required infrastructure be given at the destination of a broadcast in order to enable a readout of measured data and the further transmission of the data read to a central office.

Since mobile sensor modules have become steadily smaller, more flexible and less expensive to produce in the past, a transmission module for transmitting the measured data into the sensor modules is being integrated more and more frequently. For example, a Global System for Mobile Communications (GSM) module, a Universal Mobile Telecommunications System (UMTS) module, or modules for future standard Wide Area Network (WAN) networks can be integrated. By means of this transmission module, measurement data can already be sent to the server during the transport of the transmission, wherein the transmission can take place, for example, continuously or is triggered by an alarm when a predetermined limit value for the monitored measured variable is exceeded.

However, both continuous and spontaneous transmission of measurement data is disadvantageous in some transport areas. For example, in the case of transport in an aircraft, it is fundamentally forbidden to transmit because the transmission electronics may possibly be disturbed by the transmission signals.

From the prior art, therefore, sensor modules are known, which automatically recognize that they are in an aircraft or at least in the vicinity of an aircraft. For example, some sensor modules evaluate the state in the aircraft on the basis of pressure changes, radiation changes, etc. It is also known that sensor modules receive and evaluate a signal transmitted by a transmitter mounted in the aircraft.

However, this automatic detection of the environment is very complicated and prone to failure. In particular, the susceptibility to failure is also the reason that sometimes such sensor modules receive approval only subject to conditions or that no approval for use in air freight shipments is granted.

The object of the invention is therefore to provide a device for recording and transmitting measurement data for at least one measured variable, which is simple in design and in which the transmission can be controlled reliably, so that an approval for air freight shipments is easy to get.

A further object of the invention is a method for recording and transmitting measured data for at least one measured variable in which such a device can be used.

This object is achieved by a device having the features of independent claim 1. Advantageous developments of the device will become apparent from the dependent claims 2 to 8. The object is further achieved by a method according to claim 9. Advantageous embodiments of this method will become apparent from the dependent claims 10 to 15.

The invention provides a device for recording and transmitting measurement data for at least one measured variable. The device comprises at least one measuring module for recording the measured data, a memory for storing the measured data, a transmission module for transmitting the measured data and an activating element for activating and / or deactivating a transmission process for the measured data by means of the transmission module, wherein the measuring module, the memory, the Transmission module and the activation element of an electronics for controlling recording and transmission of the measured data are assigned. The activation element comprises at least one manual switching element having a first and a second switching state, wherein an electrical signal can be triggered by a change between the two switching states, by which the transfer process can be activated and / or deactivated. In this case, the transmission module is deactivated in the first switching state, so that no measured data can be transmitted and activated in the second switching state, so that measured data can be transmitted. A transmission of measurement data can be done for example to a central monitoring unit, the sender and / or receiver. The switching element has a fuse which prevents at least an unintentional change from the first switching state to the second switching state of the switching element. This prevents measurement data from being transferred unintentionally. If the fuse also provides that an unintentional change from the second to the first switching state is prevented, it is thus also possible to prevent an already started transmission process from being terminated unintentionally.

With such a device is achieved that the measurement data is not automatically transmitted after recording and storage, but that defines the transmission of measurement data, for example, after completion of a transport of goods to be monitored or at a fixed stopover of the transport, manually started and again can be stopped. In this case, the transmission process is activated and / or deactivated by an electrical signal which can be triggered by means of a switching element. A person at the destination can thus operate the switching element manually in a simple manner after having removed the sensor module from, for example, a transport container, but the person must overcome a fuse which would otherwise prevent an unintentional switching operation. The measured data recorded during transport are then sent by the transmission module.

An embodiment of the device provides that the electrical signal can be triggered by means of the activation element and that the activation element has means for forwarding the electrical signal to the electronics.

In a further development of the device, the electronics comprises means for evaluating the time sequence of signals of the activation element, wherein the transmission process can be activated by a first signal of the activation element to the electronics, while the transmission process can be deactivated by a subsequent second signal of the activation element to the electronics , This ensures that the transfer process can be started and stopped in a defined manner and that a transfer process is not started multiple times.

An embodiment of the device includes that the switching element is designed as an electromechanical switching element. In a further development of the device it is provided that the switching element is mechanically actuated. A mechanical operation is easy and quick to implement and can be performed by any person without complex technical facilities.

An embodiment of the device is characterized in that the switching element comprises a latching mechanism, wherein the latching mechanism at a first stop a first detent position and at a second stop has a second detent position and wherein the switching element displaceable on an axis and for the change of a detent position in the other detent position is rotatable. The two locking positions effectively prevent the switching state of the switching element can be changed unintentionally, since the switching element must be actively pulled out of the locking positions. Otherwise, a rotation of the switching element and an associated change of the switching state are not possible.

Another embodiment of the device provides that the switching element comprises a movable bracket, wherein the switching element at a first stop a first switching position and at a second stop has a second switching position and wherein the bracket in the first and second switching position can be folded and wherein the switching element for the change from one switching position to the other switching position rotatable and the bracket for the rotation can be set up. Here, the bracket prevents accidental change of the switching state, since the switching element is rotatable only with erected strap.

In a further embodiment of the device from the switching element from a cover element arranged. This cover prevents the switching element. is inadvertently actuated and that thereby an unscheduled electrical signal is triggered, which in turn activates or deactivates the transmission process for the measurement data. Only a manual removal of the cover allows actuation of the switching element.

The invention further comprises a method for recording and transmitting measurement data for at least one measured variable with a device according to the preceding description. In the method, a measurement module records measurement data that is stored in a memory. A transmission module transmits the measurement data, and an activation element activates and / or deactivates a transmission process for transmitting the measurement data by means of the transmission module, with electronics controlling the recording and transmission of the measurement data. By changing the switching state of the at least one switching element, an electrical signal is generated, this signal triggers an activation and / or deactivation of the transmission process via the electronics. The transmission module is deactivated in a first switching state of the switching element, so that no measurement data is transmitted from the transmission module and the transmission module is activated in a second switching state of the switching element, so that transmitted data from the transmission module. For switching from the second switching state to the first switching state of the switching element, the effect of a fuse of the switching element off.

An embodiment of the method is characterized in that the activation element generates the electrical signal and forwards it to the electronics.

In a further development of the method, the switching element for changing the switching state is mechanically actuated.

An embodiment of the method provides that the switching element is pulled out for actuation at a first stop from a first detent position and then rotated to a second stop, and that the switching element slides in this second stop in a second detent position.

In another embodiment of the method, it is provided that for actuating the switching element to a first stop in a first switching position, a movable bracket of the switching element is placed, then that the switching element is rotated with the erected bracket from the first stop to the second stop, and that the bracket of the switching element is folded over at the second stop in a second switching position again.

In a further embodiment of the method, a cover element is removed from the switching element before a change in the switching state of the switching element.

A refinement of the method includes that the switching element for the transmission of the measured data is brought from the first to the second switching state, and that the activation element thereby generates a first electrical signal and forwards it to the electronics, whereby the transmission process is activated. For an interruption in the transmission of the measured data, the switching element is brought from the second again in the first switching state, so that the activation element thereby generates a second electrical signal and forwards to the electronics, whereby the transmission process is deactivated.

The described device and the associated method for recording and transmitting measurement data for at least one measured variable have the advantage that a transmission process of measurement data from a sensor module to a remote location can be easily activated and / or deactivated by an electrical signal. This can in turn be triggered manually at a location where no special infrastructure must be provided for. For this purpose, the device comprises at least one switching element with a first and a second switching state. When changing the switching state, the electrical signal is triggered by means of an activation element and transmitted to an electronics, which in turn starts the transmission process. In a renewed change of the switching state of the switching element, a further electrical signal is transmitted to the electronics, which then ends the transfer process.

The invention thus turns away from devices with a continuous or alarm-induced transmission of measurement data. The transfer process is triggered only when needed, for example when a monitored transport has reached the recipient. The fuse on the switching element ensures that a transmission process can not be triggered unintentionally, since a significant manual activity is required to trigger the transmission process. Thus, a transport in an aircraft, for example, no longer be disturbed by radio signals, so that a corresponding approval of the sensor module for monitoring of air freight is possible.

The invention further turns away from devices with an automatic environment detection, which is technically very complicated and therefore cost-intensive and also often very susceptible to interference and works unreliable. Rather, the transmission process is triggered manually by means of an integrated switching element, so that it is ensured that the time for the transmission process can be planned. This makes it possible to realize a robust device that is easy to handle.

The above and other advantages, features and expedient developments of the invention will become apparent from the embodiments, which are described below with reference to the figures.

From the figures shows:

1a 1 is a schematic representation of a front view of a sensor module with a switching element,

1b a schematic rear view of the sensor module,

4a an embodiment of a switching element with a cover, and

4b a bottom of a cover.

In 1a is schematically as an example the front view of a sensor module 101 for recording and transmitting measured data for at least one measured variable. The sensor module 101 has as components a carrier element 102 , a measuring module 103 with a probe 104 (or only with a connection option for a sensor), a memory 105 , a transmission module 106 , an electronics 107 with a battery 108 and an activation element 109 with a switching element 110 with fuse on.

The carrier element 102 of the sensor module 101 serves to accommodate the individual components for the sensor module 101 , It is designed for example as a printed circuit board, which consists of one or more layers of material. Materials for printed circuit boards are well known in the art and may be selected as appropriate by those skilled in the art.

For attachment of the individual components on the support element 102 There are various options available. The components may, for example, on the support element 102 glued or welded or soldered on. In addition, it is possible to stick one or more components and to weld or solder the other components.

The carrier element equipped with the various components 102 of the sensor module 101 can then be integrated, for example, completely into a housing, not shown, depending on the field of application. It is also possible, only a cover over the components of the sensor module 101 to arrange or the sensor module 101 without further protection.

The recording of the measured data takes place via the measuring module 103 , This is indicated by the measuring module 103 a sensor 104 which is, for example, a temperature sensor for recording and recording temperature measurement data. However, other sensors can also be used, for example for detecting moisture or pressure measurements. Also the integration of several different sensors in the measuring module 103 is possible.

If only connections are provided for a sensor, it is possible, depending on the application, a corresponding sensor 104 select so that the sensor module 101 is very variable.

The from the measuring module 103 recorded measurement data are sent to the memory 105 transferred and stored there. There is a difference between the measuring module 103 and the memory 105 a corresponding electrical connection.

An electrical connection also exists between the memory 105 and the transmission module 106 that in the store 105 For example, stored measurement data is transmitted to a central system for further processing and evaluation of the measurement data. This system can work For example, the sender or recipient of the transport consignment, but also the transport company itself. It is also possible that the measurement data are transmitted to several systems for processing and evaluation.

As a transmission module 106 suitable, for example, a GSM module (Global System for Mobile Communications). GSM modules use the GSM mobile standard as a second-generation wireless standard for transmitting data, which is very widespread because of its use in mobile communications. Accordingly, the existing mobile stations can be used to receive the data.

Also suitable as a transmission module 106 are Universal Mobile Telecommunications System (UMTS) modules that use the UMTS wireless standard as the third generation wireless communication standard or future WAN standards.

Another possible transmission module 106 is designed, for example, as an RFID module (radio-frequency identification). Since RFID modules work on the basis of transponder and reader, it must therefore be ensured that in the vicinity of the sensor module 101 sufficient receiving stations are available for the data sent. Since the sensor module according to the invention is particularly suitable for initiating a transmission process of previously recorded measurement data in a location where no special infrastructure must be present, however, GSM and / or UMTS modules have proven to be more advantageous for the invention.

Recording and transmission of the measured data are controlled by electronics 107 , There are between the electronics 107 and the other components of the sensor module 101 electrical connections for transmission of corresponding control commands.

This also has electrical connections to the electronics 107 connected activation element 109 initiates the switching process to activate or deactivate a transfer process for the measurement data. This is indicated by the activation element 109 at least one switching element 110 with fuse on.

As a switching element 110 For example, an electromechanical switch can be used with a mechanical actuator. An electromechanical switch is a component which establishes or separates an electrically conductive connection by means of two electrically conductive materials or a semiconductor component. This electrical connection defines the switching state of the switch. Is there an electrical connection, the switch is in the switching state 'closed' and there is no electrical connection, the switch is in the switching state 'open'. By opening and closing the switch electrical signals are generated, via the corresponding switching operations for associated components, such as a transmission module for the transmission of measurement data, can be initiated.

Electromechanical switches differ from each other in particular by the integrated mechanism for establishing and disconnecting the electrical connection. Depending on the application, a variety of different mechanisms are known that can be used in an electromechanical switch, such as tilt, rocker, push, latch, slide, turn, step or tactile mechanisms.

The switching element 110 In addition to the mechanism for producing and disconnecting the electrical connection also has a fuse, which ensures that the switching state of the switching element 110 only planned can be changed. This ensures that a transfer operation is started or stopped only when the switching element 110 was deliberately operated. Possible embodiments for a switching element 110 with a backup will be in the below below 2 . 3 and 4 described in more detail.

The sensor module 101 is by means of a fastener 111 fixable on any object, so that a mobile and flexible use of the sensor module 101 is possible. 1b schematically shows a rear view of the sensor module 101 on which the fastener 111 is arranged by way of example. As a fastener 111 For example, an adhesive surface appears suitable with which the sensor module 101 can be easily adhered to the object. A Velcro surface or other suitable devices are as a fastener 111 but also conceivable.

Suitable objects for mounting the sensor module 101 are, for example, various transport packaging, such as boxes, containers, lattice boxes or pallets. The sensor module 101 can be mounted both on the outside and on the inside of the object. Also possible is the sensor module 101 to be attached to or in a transport container or in a cargo hold of a transport device.

The arrangement of the fastener 111 on the back of the sensor module 101 has the advantage that the components of the sensor module 101 are freely accessible. The fastener 111 but also on the front of the sensor module 101 or be arranged on a housing into which the sensor module 101 is integrated.

With the sensor module 101 Measurement data for a measured variable can be recorded as well as transmitted. The recording of the measurement data is carried out continuously over a period of time to be defined and the time intervals for the recording of individual measurement data are arbitrary.

A measurement process is started to record measurement data, for example at the beginning of a transport at the sender location of a transport program to be monitored. After the start of the measuring process, the sensor starts 104 of the measuring module 103 with the recording of measured data. These measurement data are transmitted to the memory via existing electrical connections 105 forwarded and filed there. The measuring process is stopped, for example, when the transport consignment has reached its destination. For the start and stop of the measuring process but also other times or locations can be selected.

The start and stop function for the measuring process are via an unillustrated switching element on the sensor module 101 realized. Suitable as a switching element appear, for example, mechanical switches or buttons. But there are also conceivable electrical switching elements that can be switched, for example by means of radio. Other mechanisms for triggering a switching operation, such as the use of optical signals, are also possible.

After completion of the measurement process, the measurement data must be read from memory for further processing and evaluation 105 of the sensor module 101 be read out. For this, a transmission of the measured data to a central system usually takes place.

A transfer process is started to transfer the measurement data from the memory 105 via the activation element 109 , To activate the transfer process, the switching element 110 of the activation element 109 manually operated, with the operation of the effect of a corresponding fuse for the switching element 110 must be turned off. By the operation, the switching element 110 brought from an open switching state to a closed switching state. This means that in the switching element 110 is made by means of two electrically conductive materials or a semiconductor element, an electrically conductive connection. The case in the activation element 109 generated electrical signal is transmitted through the existing electrical connections to the electronics 107 transmit the signal through the existing electrical connections to the transmission module 106 forwards. Then the transmission module begins 106 with the transmission of the measured data from the memory 105 ,

In addition to the transmission of the electrical signal to the transmission module 106 To activate the transmission process, the electrical signal from the electronics 107 also to the measuring module 103 be forwarded and there complete the measuring process accordingly. This automatically stops the measuring process and does not have to be stopped separately. The forwarding of the electrical signal to the transmission module 106 and to the measurement module 103 can be done both simultaneously and with a time delay.

A transmission process for transmitting the measurement data from the memory is stopped 105 also via the activation element 109 , To deactivate the transmission process, the switching element 110 of the activation element 109 manually operated again, whereby also the effect of the fuse for the switching element 110 must be turned off. By this re-operation, the switching element 110 brought from the closed switching state back to the open switching state. This means that the electrically conductive connection is disconnected again. The case in the activation element 109 generated electrical signal is also via the existing electrical connections to the electronics 107 This also transmits this signal over the existing electrical connections to the transmission module 106 forwards. Then the transmission module ends 106 the transmission of the measured data from the memory 105 ,

However, the transmission process can also end automatically if all measurement data from the transmission module 106 from the store 105 transferred to the central system.

The use of electronics 107 for forwarding the signals from the activation element 109 to the transmission module 106 designed as shown above, although advantageous, but not mandatory. It is also possible to receive the electrical signals directly from the activation element 109 to the transmission module 106 forward. Also, it is not necessary to work with electrical signals. Rather, other signals, such as radio signals or optical signals can be used.

As already stated above, are for the switching element 110 different embodiments conceivable. In 2a is schematically the example of a switching element 110 with a Locking mechanism and a handle element 201 Because of its dimensions, such a switching element is more suitable for a sensor module the size of a mobile phone than for a very small and flat sensor module with printed components. In the switching element 110 is ensured by the integrated locking mechanism that a change between the two switching states of the switching element 110 and thus an activation or deactivation of a transfer process is only planned executable. The switching element 110 includes a first stop A for a first switching state and a second stop B for a second switching state.

In 2 B is an example of a section XX through the switching element 110 shown. The switching element 110 has a latching element 202 on, which forms part of the locking mechanism. At stop A, the locking element engages 202 in a recess 203 as the first detent position, which forms a further part of the latching mechanism and in the carrier element 102 of the sensor module 101 is trained. The stop B is in the carrier element 102 of the sensor module 101 a comparable recess 203 ' as a second detent position, which also forms part of the latching mechanism, in 2 B but not shown. Also not shown are other components of the switching element 110 , Such as spring elements or electrical contact elements, for the function of the switching element 110 however, they are required.

In a first switching state, the switching element is located 110 on the stop A in the first detent position at which the switching element 110 is open. To close the switching element 110 by means of the grip element 201 pulled on the stop A out of the first detent position upwards and then twisted in the direction of the stop B. At stop B, the switching element slides 110 in the second detent position in which the switching element 110 then in a second switching state, in which the switching element 110 closed is.

To reopen the switching element 110 becomes the switching element 110 by means of the grip element 201 pulled on the stop B from the second detent position upwards and then rotated in the direction of stop A. At stop A, the switching element slides 110 then in the first detent position in which the switching element 110 is again in the first switching state and is open. The directions of rotation for the switching element 110 are marked with a corresponding arrow.

For the execution of the rotation and displacement movements is the switching element 110 both rotatable and displaceable on one axis 204 stored, which also in the support element 102 of the sensor module 101 is integrated. The axis 204 has a covenant 205 on, so in the switching element 110 engages that ensures that the switching element 110 while pulling out of one of the two detent positions not from the axle 204 can be deducted.

3a schematically shows the example of another embodiment of a switching element 110 ' that has a hanger 301 having. This temple 301 Realizes the fuse of the switching element 110 ' against an unintended change between the two switching states of the switching element 110 ' ,

In 3b is an example of a section XX through the switching element 110 ' with the strap 301 shown, which is a stop element 302 having. Stop A and stop B of the switching element 110 ' are each as a pin on the support element 102 of the sensor module 101 educated. The stop element 302 of the temple 301 fails in the first switching state of the switching element 110 ' to the stop A and in the second switching state to the stop B on. Not shown are other components of the switching element 110 ' , Such as spring elements or electrical contact elements, for the function of the switching element 110 ' however, they are required.

In the first switching state, the switching element is located 110 ' on the stop A, where the switching element 110 ' is open. To close the switching element 110 ' becomes the hanger 301 of the switching element 110 ' placed on the stop A and then the switching element 110 ' by means of the strap 301 twisted in the direction of the stop B. At the stop B, the bracket 301 again folded and the switching element 110 ' is in the second switching state in which the switching element 110 ' closed is. The switching element 110 ' can only be twisted when the hanger 301 is set up.

To reopen the switching element 110 ' becomes the hanger 301 of the switching element 110 ' placed on the stop B and then the switching element 110 ' by means of the strap 301 twisted in the direction of stop A. At the stop A is the hanger 301 again folded and the switching element 110 ' is again in the first switching state and is open. The directions of rotation of the switching element 110 ' are also marked here with a corresponding arrow.

The switching element 110 ' is rotatable on one axis for carrying out the rotational movements 303 stored, which also in the support element 102 of the sensor module 101 is integrated.

Instead of the temple 301 for securing the switching element 110 ' For example, a key is used with which the switching element 110 ' can be unlocked before twisting the switching element 110 ' from stop A to stop B or vice versa is possible.

4a shows the example of a cover 401 as another way to secure a switching element 110 '' , In this embodiment, the switching element 110 '' for example, as a slide switch with the switch positions '0' and 'I' and the cover 401 designed as a sliding element. Both the displacement directions for the switching element 110 '' as well as for the cover 401 are each marked with an arrow.

The cover element 401 is so over the switching element 110 '' arranged that it is prior to actuation of the switching element 110 '' first has to be removed. By an embodiment of the cover 401 as a sliding element there is the possibility of the cover 401 after an actuation of the switching element 110 '' again above the switching element 110 '' to arrange and the switching element 110 '' To protect again from accidental actuation. In one embodiment of the cover 401 as a folding element this also appears possible.

A further increase in security against unintentional actuation of the switching element 110 '' is achieved by at the bottom of the cover 401 a latch element 402 is arranged as in 4b exemplified.

This latch element 402 is so on the underside of the cover 401 attached that the cover 401 only lets move when the switching element 110 '' in switch position '0'. Is the switch element 110 '' while in switch position 'I', the cover 401 however, not moved and thus not again on the switching element 110 '' to be ordered.

As long as the cover 401 above the switching element 110 '' is arranged, is also a change in the switching state of the switching element 110 '' from '0' to 'I' not possible because the switching element 110 '' from the latch member 402 is blocked so that a shifting of the switching element 110 '' not possible.

The use of a latch element 402 However, this is not mandatory. Rather, the cover 401 also without latch element 402 be executed.

The embodiments described here for a switching element 110 with a backup are only examples and not to be considered exhaustive. Rather, other suitable switching and securing mechanisms may be used in a sensor module 101 Find.

The described sensor module 101 is flexible and versatile, in particular because of its simple and reliable activation and deactivation process for the transfer process. The device according to the invention and the associated method can thus be used particularly advantageously in areas of logistics in which measured variables such as the ambient temperature of transported goods must be monitored. The switching element allows a simple but effective and secure control of the transmission process.
