Description

The invention relates to a method for monitoring one or more monitoring areas and / or monitoring objects. In particular, the monitoring area is arranged on a commercial vehicle or a building and / or the commercial vehicle or the building is the monitoring object to be monitored.

In the method, one parameter value or several parameter values of one monitoring parameter or several monitoring parameters are recorded. In this case, the one or more monitoring parameters have their / their parameter value or their / their parameter values at a respective detection time. Thus, parameter values are recorded, each of which corresponds to a respective detection time, with a corresponding monitoring parameter having the corresponding parameter value at the respective detection time.

For example, the parameter values are detected, in particular by a detection device, or the parameter values are received by means of one or more data signals.

Such methods are known from the prior art.

The known methods have the problem that they are susceptible to failure, in particular in a mobile environment, such as in road traffic, and that false triggering occurs frequently. The methods are also susceptible to faults in stationary applications and false triggering occurs because, for example, moving air occurs in the monitoring area or in the vicinity of or near the monitoring object when there is a wind or other interference.

The invention is therefore based on the problem of improving the known methods, in particular that they become less susceptible to faults and, for example, events which are relevant for monitoring are detected efficiently.

According to the invention, this problem is solved in a method of the type mentioned at the outset in that an evaluation is carried out, several parameter values corresponding to different detection times being included in the evaluation, and based on this evaluation at least one status criterion about a status of the monitoring area and / or the monitoring object a status value is assigned.

One of the advantages of the invention can be seen in the fact that the assignment of the state value is based on an evaluation of parameter values at different detection times, and thus individual incorrect measurements influence the evaluation and thus the assignment of the state value at least less and thus the method is less susceptible to faults. In particular, this results in fewer false triggers.

In particular, it is provided that a result of the evaluation, which is, in particular, the assignment of the status value, of the parameter values, which at least one monitoring parameter, preferably of the respective parameter values, the several, for example all, monitoring parameters, at several preceding detection times, in particular at least three preceding ones Detection points in time, for example at least ten previous detection points in time, has been influenced.

A wide variety of types of monitoring parameters can be used in the method.

In a preferred embodiment it is provided that at least one monitoring parameter corresponds to the presence of a foreign object in the monitoring area. For example, the monitoring parameter is the presence of a foreign object in the monitoring area.

In this way, it can be determined, for example, whether there are potentially security-threatening objects in the monitoring area and an action may be required. In addition, it can thus be determined whether at least one potentially unauthorized person is in the surveillance area.

In particularly preferred embodiments, it is provided that at least one monitoring parameter corresponds to a distance of an object, in particular the foreign object and / or the monitoring object, to a reference point. In particular, it is provided that this distance is at least one monitoring parameter.

For example, the reference point is the monitoring object, and thus the monitoring parameter corresponds, for example, to the distance of the foreign object from the monitoring object.

One advantage can be seen in the fact that the distance monitoring is an action of itself unauthorized person in the surveillance area or a movement of the foreign object in the surveillance area can be better analyzed.

In particularly advantageous embodiments, it is provided that at least one monitoring parameter corresponds to a state, in particular of the monitoring object, in particular that the monitoring parameter is this state.

This has the advantage that the status of the monitoring object is monitored directly, and thus, for example, safety-related and / or transport-relevant changes in the status are monitored directly.

For example, the monitored state is a state of a tank device of the commercial vehicle. This has the advantage that the tank device that is important for the transport is monitored directly. Since fuel is stored in particular in the tank device, a safety-relevant area of the commercial vehicle is also monitored.

In some preferred embodiments, in particular the tank device is monitored for a tank opening thereof, for example by monitoring the state of the tank opening, whether it is closed or open.

In some preferred embodiments, the monitoring parameter corresponds to a state of a charging device of the commercial vehicle, in particular the monitoring parameter is the state of this charging device.

For example, a proper condition of goods to be transported is monitored.

In some advantageous embodiments, a state of a loading opening of the loading device is a monitoring parameter.

The transport and safety-relevant area of the loading device, in particular the loading opening, is thus monitored, for example in order to monitor a loss of transport goods, which can result in safety risks.

In particular, the monitoring of the tank device and / or the loading device can also be carried out for monitoring the potential theft of, for example, fuel and / or transport goods.

In some particularly advantageous embodiments, at least one monitored state is a driving speed and / or a position of the commercial vehicle. This has the particular advantage that the detected state can be compared with other parameters and thus safety-relevant and / or transport-relevant fault states can be determined. In addition, interference effects in other monitoring parameters can be eliminated by determining the travel speed.

In some particularly preferred embodiments it is provided that the evaluation comprises a comparison of a parameter value of at least one monitoring parameter, in particular several, for example all, parameter values of a monitoring parameter with a pre-stored data record. This has the advantage that the evaluation can be refined, for example, by comparing the detected parameter values with values from the pre-stored data record and thus with expected values.

For example, the evaluation includes such a comparison with regard to several monitoring parameters.

In particular, the comparison includes a determination of whether a parameter value, in particular a plurality of parameter values, of the at least one monitoring parameter corresponds to a pre-stored target value at a respective detection time.

For example, a travel route of the commercial vehicle can be stored in the pre-stored data record and, by comparing the received parameter values with the pre-stored target values, a deviation of the commercial vehicle from the pre-stored route can be determined, for example, or it can be determined whether the tank device and / or loading device on pre-stored, fixed times and locations is opened or is opened at different locations and / or times and thus there is a security risk or transport risk or a potential theft.

In particularly preferred embodiments it is provided that the evaluation includes a comparison of the parameter values at different detection times of at least one monitoring parameter with one another. Thus, with regard to at least one monitoring parameter, its parameter values, which it has at different detection times, are compared with one another. In particular, the evaluation includes a temporal development of the Parameter values of the at least one monitoring parameter.

This offers the advantage that by comparing the parameter values at different points in time, individual incorrect measurements can be determined better and can be filtered out, for example, and the method thus becomes less susceptible to faults.

In particular, it is provided that a temporal development of the parameter value of at least one monitoring parameter is also a monitoring parameter.

Thus, for example, by monitoring the temporal development of the at least one monitoring parameter, a movement and / or action, for example of the foreign object or the unauthorized person in the monitoring area, can be better monitored.

For example, monitoring the variance of the distance is provided for the distance measurement.

In particular, the deviation of the distance from one detection time to the next detection time is the monitoring parameter. Thus, for example, by monitoring the variance in distance, an immovable foreign object in the monitoring area can be distinguished from a person in the monitoring area.

In particular, the distance variance, that is to say the difference between the detected distances at two, in particular directly successive, detection times, is provided in order to distinguish static foreign objects from persons who are in the surveillance area.

In particular, in the case of a distance variance in which the distance changes by at least 1 cm, for example by at least 5 cm, within about 3 seconds, it is evaluated that a foreign object in the monitoring area is a person and not a static foreign object.

In particular, it is provided that the evaluation includes the storage of the received parameter values.

In particular, the evaluation includes a classification of the parameter values of at least one monitoring parameter, in particular the parameter values of all monitoring parameters.

In particular, they are classified into at least two categories. For example, the parameter values are classified into two categories, one category corresponding to a critical parameter value and one category corresponding to an uncritical parameter value.

In some embodiments, classification into three or more categories is provided.

In particular, it is provided that at least two status values can be assigned to the status criterion.

In particular, a state value corresponds to an uncritical state, in which in particular no further action is necessary. A second status value corresponds in particular to a critical status, which in particular corresponds to an incorrect status and in which, for safety reasons, for example, a remedial action should be taken.

In preferred embodiments it is provided that the status value is assigned as a function of the classification of a monitoring parameter, in particular as a function of the classification of several, for example all, monitoring parameters.

It is particularly advantageous if the status value is assigned as a function of a sequence of the classifications of a monitoring parameter, in particular a plurality of monitoring parameters, for example all monitoring parameters. Since the assignment depends on the chronological order and the category in which the respective monitoring parameter was classified, the influence of individual incorrect measurements is preferably reduced and the method is therefore less susceptible to faults.

For example, the status value is assigned as a function of a number of classifications of a monitoring parameter, in particular a plurality of monitoring parameters, for example all monitoring parameters, into a predetermined category in a predetermined time interval.

The predetermined time interval is for example at least 1 second, preferably at least 5 seconds, in particular at least 10 seconds long and / or the predetermined time interval is at most 2 minutes, preferably at most 1 minute.

In some embodiments, the time interval is determined by a number of successive detection times. In this case, for example, at least three successive detection times correspond, in particular at least ten successive detection times correspond to the predetermined time interval and / or correspond to at most fifty successive detection times, in particular at most thirty successive detection times correspond to the predetermined time interval.

In particular, the predetermined category is that category which corresponds to a critical parameter value.

The assignment of the status value thus depends in particular on the number of times at least one monitoring parameter, preferably a plurality of monitoring parameters, for example all monitoring parameters, are classified as critical in the predetermined time interval.

In particular, the assignment of the status value, in particular the assignment of the status value corresponding to a critical status, takes place depending on the achievement of a minimum number of classifications of at least one monitoring parameter, preferably a plurality of monitoring parameters, in particular all monitoring parameters, in the predetermined category, which corresponds in particular to a critical parameter value the predetermined time interval. For example, the minimum number corresponds to at least half, in particular at least three quarters, the number of detection times in the predetermined time interval.

For example, the status value is assigned, in particular the status value corresponding to a critical status is assigned, depending on whether at least one monitoring parameter, in particular a plurality of monitoring parameters, for example all monitoring parameters, were always only classified as critical in the predetermined time interval in the predetermined time interval.

In preferred embodiments, it is provided that the method controls activation of an actuator.

In particular, it is provided that an activation signal for an actuator is provided as a function of the assigned status value.

In particularly preferred embodiments, an actuator is activated as a function of the assigned status value, in particular when the activation signal is provided.

In particular, the activation signal is provided and the actuator is preferably activated when an activation state value is assigned to the state criterion. In particular, the activation state value corresponds to the state value, which corresponds to a critical state.

In particular, the method comprises providing a deactivation signal, in particular for deactivating the activated actuator.

For example, the method includes the deactivation of the activated actuator, in particular as a result of the provision of the deactivation signal.

In preferred embodiments it is provided that the deactivation signal, in particular the deactivation of the activated actuator, is provided as a function of the classification of at least one monitoring parameter, in particular as a function of the classification of a plurality of monitoring parameters, preferably all of the monitoring parameters.

It is particularly advantageous if the deactivation signal, in particular the deactivation of the activated actuator, is provided at the latest when an activation maximum period has elapsed. Thus, for example, an undesirably long running time of the actuator in the event of repeated interferences is avoided and / or a resource-saving solution is provided, since an activation time of the actuator is limited to the maximum activation period.

In particular, the maximum activation period begins with the provision of the activation signal or with the activation of the actuator.

In particular, it is provided that after the deactivation signal is provided, in particular after the deactivation of the actuator, the activation state value is reassigned, in particular the activation signal is provided again, for example the actuator is reactivated, after a predefined dead time period at the earliest. In the case of recurring interferences, for example, an excessive activation of the actuator is thus avoided and the process is thus less susceptible to faults and saves resources.

In addition, for some uses, for example when used as monitoring for theft protection, it is sufficient to detect only individual activities, so that resources, for example a limited memory space, are used economically by the actuator due to the dead time provided.

In some particularly preferred embodiments it is provided that the possibility is provided that an activated actuator can be deactivated by a user.

Another aspect of the invention relates to the use of a monitoring system which comprises at least one detection device, one evaluation device and one actuator device with one actuator. In particular, it is provided that the monitoring system is used to monitor a transport-relevant area of a commercial vehicle.

For example, monitoring of the transport-relevant area is provided to determine security risks.

In particularly preferred embodiments, the use of the monitoring system for detecting thefts is provided. In this case, the monitoring system is used in particular to monitor a tank device of the commercial vehicle and / or a loading device of the commercial vehicle, in particular a loading opening thereof, and to register potential thefts of fuel from the tank device and / or transport goods from the loading device.

In particular, it is provided that at least the detection device is arranged on a tank side of the commercial vehicle.

The tank side of the commercial vehicle is in particular a side of the commercial vehicle on which the tank device, in particular a tank container thereof, is arranged.

In a further advantageous embodiment, it is provided that at least the detection device and / or the actuator device is arranged in a loading space of the commercial vehicle.

In particularly preferred embodiments, it is provided that at least the detection device and / or the evaluation device and / or at least one actuator of the actuator device, in particular the entire actuator device, is to be arranged, in particular arranged, in a receiving part of the utility vehicle. It is particularly preferred if the entire monitoring system is to be arranged, in particular arranged, in the receiving part of the commercial vehicle.

In particular, this provides a space-saving solution and is particularly resource-saving, since the receiving part serves as a receptacle for the device of the monitoring system or of the monitoring system itself.

Another advantage is that if the surveillance system is used to monitor theft, the surveillance system can be arranged inconspicuously on the commercial vehicle and thus a deterrent potential is increased since people who want to carry out theft are ignorant of whether a surveillance area of the commercial vehicle is monitored.

In particularly advantageous embodiments, it is provided that at least the detection device and / or the evaluation device and / or at least one actuator of the actuator device, in particular the entire actuator device, is arranged behind an, in particular almost opaque, cover, as seen from outside the utility vehicle. It is particularly preferred if the entire monitoring system is arranged behind the veneer.

In particular, an almost opaque veneer is to be understood to mean a veneer in which at most 50%, in particular at most 70%, for example at most 85%, of light incident on the veneer, in particular light in the spectral range visible to humans, is transmitted through the veneer and / or at least 2%, preferably at least 5%, of this light transmitted through the veneer.

This has the advantage, in particular in the case of a surveillance system provided for theft protection, that the surveillance system is at least very difficult to detect from outside the commercial vehicle and thus the deterrent potential is increased.

For example, the monitoring system, in particular with the base body, is designed as an insertion part in the receiving part.

In other preferred embodiments, it is provided that the monitoring system has its own housing, which is designed in particular in the manner of a receiving part of the commercial vehicle. Thus, the commercial vehicle can be retrofitted with the monitoring system and since the housing looks optically like a component of the commercial vehicle, it is again at least difficult to see whether or that the commercial vehicle is equipped with the monitoring system, which in turn increases a deterrent potential.

For example, the monitoring system, in particular its base body and / or its housing, has an elongated extension. In particular, an extension thereof in an elongated direction of extension is at least 10 cm, for example at least 20 cm long and / or at most 100 cm, in particular at most 60 cm long. For example, an extension thereof perpendicular to the elongated direction of extension is at least 2 cm and / or at most 10 cm, for example approximately 4 cm in size.

In a second embodiment of a monitoring system 10th are elements and features with at least fundamentally the same function provided with the same reference numerals as in the first embodiment and with regard to the description thereof, reference is made in full to the above statements in connection with the first embodiment.

In the second embodiment, the monitoring system 10th for monitoring a stationary monitoring area 12th or a stationary monitoring object 12th intended.

In particular, the stationary monitoring object 12th a building 272 and in particular the stationary surveillance area is a property 274 especially with the building 272 .

For example, at least the detection device 112 and / or the actuator device 116 on a limiting device 278 arranged, the limiting device 278 at least partially on a boundary of the property 274 runs and / or at least partially the building 272 surrounds.

In a variant of the exemplary embodiment, it is provided that the detection device is at least partially supplementary or alternative 112 and / or the actuator device 116 on the building 272 is arranged.

For example, in the embodiments 1 and 2nd a method for monitoring the monitoring area or monitoring object 12th and in particular a method for activating and deactivating the actuator 142 applied as explained below.

The method comprises a step 312 of receiving data signals, the data signals each comprising at least one parameter value of at least one monitoring parameter at a respective time of detection.

The method also includes an evaluation 314 , in which the received parameter values are evaluated and in particular a status criterion about a status of the monitoring area or monitoring object 12th a status value is assigned.

In particular, the method also includes an overall 316 designated control of the actuator device 116 .

The parameter values are from the detection device 112 detected at regular intervals at the respective detection times.

In this embodiment, the presence of the foreign object in the surveillance area 12th and provided a foreign object in the surveillance area 12th the distance of this foreign object to a reference point is present, in particular to the monitoring object 12th , especially the tank device 52 , detected.

The detection device 112 transmits the detected parameter values to the evaluation device 114 and the evaluation device 114 receives the detected parameter values, one parameter value corresponding to a corresponding time of detection.

The evaluation 314 includes in particular an activation routine 322 and a runtime control routine 324 , the evaluation 314 in these routines 322 and 324 depending on a respective classification 332 of the received parameter values.

In particular, the parameter values are classified into two categories, one category corresponding to a parameter value classified as critical and the other category corresponding to a parameter value classified as uncritical.

For example, the distance parameter value is classified as uncritical if there is no foreign object in the monitoring area 12th is present or one in the surveillance area 12th existing foreign object has a distance from the reference point that is greater than a minimum distance.

The distance parameter value is classified as critical, for example, if the distance of the foreign object to the reference point is less than or equal to the minimum distance.

Furthermore, at least in the activation routine 322 still plausibility control steps 336 , in which a plausibility of the classification of the parameter value as critical is checked for a parameter value classified as critical and, depending on this control, the status criterion of the status of the monitoring area and / or monitoring object 12th a status value corresponding to a critical status is assigned.

One of the plausibility control steps 336 includes the determination of whether the parameter value of a minimum number was classified as critical in a given time interval or more often, in particular was always classified as critical in the predetermined time interval.

Another plausibility check step 336 comprises the control of a further monitoring parameter, in particular a monitoring parameter derived from a temporal development of the classified parameter value.

In this exemplary embodiment, the distance value measurement turns into a distance variance of the foreign object in the monitoring area 12th derived and a distance variance value in turn classified into at least two categories.

The distance variance value corresponds to a difference between two distance values at different, in particular directly successive, detection times.

In particular, the distance variance parameter is classified as critical if the distance variance value is greater than a minimum variance value and smaller than a maximum variance value. The previous classification of the distance parameter is then classified as critical as plausible.

The distance variance parameter is particularly classified as uncritical if its value is greater than the maximum variance value or smaller than the minimum variance value. In this way, the previous classification of the distance parameter is classified as critical as not relevant for this situation and therefore implausible.

If the monitoring parameters are classified as critical to the extent necessary, the status of the monitoring area or monitoring object is determined 12th assigned a critical condition value.

In particular, an assignment is made 342 an activation state value and an activity signal 344 is from the evaluation device 114 provided, output and to the actuator device 116 transmitted.

With the assignment 342 of the activity status value to the status criterion is started 352 the runtime control routine 324 .

During the runtime control routine 324 is based on the classification 332 of the monitoring parameter controls a period of time in which the activation criterion is assigned to the status criterion, and in particular a runtime of the actuator 142 controlled.

In particular, with the start 352 a runtime duration is set to a minimum runtime value and a period of the runtime starts from the start 352 to run.

For example, the value of the term of each classification 332 of the monitoring parameter as critical increased by a predetermined time interval.

A maximum duration is preferably provided.

In particular, the runtime control routine includes 324 the finding 356 an abort condition.

If an abort condition is ascertained, in particular that the monitoring parameter value was no longer classified as critical over a certain period of time and / or the maximum runtime was reached, the status criterion is assigned a status value that is different from the activation status value and in particular a deactivation signal 358 from the evaluation device 114 provided and output as well as to the actuator device 116 transmitted.

With the finding 356 The termination condition becomes the runtime control routine 324 completed.

It is preferably provided that when the runtime control routine ends 324 a holding pattern 362 begins.

While on hold 362 measures the evaluation device 114 the time since the termination condition was determined 356 .

In particular, the activation routine only becomes active after a predetermined dead time has elapsed 322 started again.

• In der Aktivierungsroutine 322 wird eine Detektion initialisiert und die gemessenen Werte der Überwachungsparameter, insbesondere die Abstandswerte zu verschiedenen Detektionszeitpunkten empfangen.

The method thus runs in summary in the evaluation device 114 essentially as follows:

• In the activation routine 322 a detection is initialized and the measured values of the monitoring parameters, in particular the distance values, are received at different detection times.

If the distance value, or in the case of variants the distance values corresponding to several monitoring parameters, is smaller than a respective minimum distance value, a first plausibility check is carried out 336 . This determines whether a distance variance condition is met, i.e. whether the distance variance value is greater than the minimum variance value and smaller than the maximum variance value.

If a distance value is not less than a minimum distance value or a distance variance condition is not met, the detection is reinitialized and the aforementioned steps are repeated.

If, in addition to the classification of the parameter values as critical, the plausibility conditions are also met, this is evaluated as positive detection and, for example, a corresponding status value is assigned to the status criterion, for example a pre-critical status value is assigned.

The reception of the parameter values and their classification is then continued and if the parameter value is classified as critical in the predefined number of subsequent classifications and the plausibility conditions are met, the activation criterion and the activity signal are assigned to the status criterion 344 generated and in particular to the actuator device 116 transmitted.

With the assignment 342 of the activity state value begins the runtime control routine 324 . In this, the values of the monitoring parameters are reclassified, in particular it is determined whether the distance values are smaller than the minimum distance value.

If the monitoring parameter value is classified as critical, the activity period is increased by the predefined time interval. In addition, the total time since the runtime control routine was started 324 The runtime control routine is determined and monitored and after a maximum total runtime has elapsed 324 ended at the latest.

When the runtime control routine ends 324 becomes the deactivation signal 358 generated and in particular to the actuator device 116 transmitted.

After the runtime control routine has ended 324 In particular, it is provided that first while on hold 362 the dead time must expire before the activation routine again 322 starts.

• Bei der Übermittlung des Aktivitätssignals 344 empfängt die Aktuatorvorrichtung 116 das Aktivitätssignal 344 und es erfolgt ein Beginn 372 einer Aktivität des Aktuators, insbesondere wird also der Aktuator gestartet.

The control 316 the actuator device 116 is essentially as follows:

• When transmitting the activity signal 344 receives the actuator device 116 the activity signal 344 and there is a start 372 an activity of the actuator, in particular the actuator is started.

An activity period follows 374 during which the actuator 142 is active.

With the transmission of the deactivation signal 358 receives the actuator device 116 the deactivation signal 358 and there is an exit 376 the activity of the actuator 142 .

In the case of variants of the exemplary embodiment, it is provided, for example, that the classification 332 in the activation routine 322 and the runtime control routine 324 done differently.

In the case of variants of the exemplary embodiment, it is also provided, for example, that the runtime control routine also 324 Plausibility check steps 336 ' are provided.

In further alternatives of the exemplary embodiment, it is provided, for example, that an external monitoring point also has a deactivation signal 358 ' to the actuator device 116 can send and thus through the external monitoring body the activity of the actuator 142 can be ended. It is also provided, for example, that the activity of the actuator is carried out by means of the external monitoring point 142 can be controlled at least partially.

In further alternatives of the exemplary embodiment it is provided that in the activation routine 322 and / or the runtime control routine 324 , especially in the classification 332 and / or in one of the plausibility control steps 336 , the parameter values are compared with stored setpoints.
