- a device can be retrofitted into an existing passenger transportation system which has, for example, a multiplicity of sensors and a signal processing device for processing signals from the sensors, so that operating parameters can be monitored with the aid of this device and, for example, possible anomalies can be detected early.

- Monitor operating conditions of a passenger transport system For example, different operating parameters were repeatedly recorded on or in the passenger transport system using various sensors, and from this information was derived about their current operating status. This information could, for example, be used to remotely monitor the passenger transport system (so-called "remote controlling") and / or to be able to initiate suitable measures if abnormalities occur, as the case may be.
- the sensors either transmitted their sensor data continuously or at short intervals to a signal processing device, so that this signal processing device had to process large amounts of transmitted sensor data centrally.
- the signal processing device could centrally drive each of the sensors individually to cause it (i.e., trigger),
- Data processing bottlenecks can come. On the other hand, there may be a high data transfer volume between the signal processing device and the sensors. In particular, if the sensors communicate with the signal processing device via a common bus system, this may require that the bus system be designed for a high data transmission rate, since otherwise data transmission bottlenecks can occur.
- these sensors do not permanently measure their operating parameters to be monitored in a passenger transport system equipped with a large number of different sensors or at least that signals are not permanently transmitted to the signal processing system. Forward facility and process there. Instead, it is proposed that such measurement of operating parameters or transmission of signals be carried out only if this was specifically caused by means of triggering. In this way, requirements for data processing and / or data transmission can be massively reduced.
- the triggering of a sensor should be triggered directly or indirectly by another sensor.
- the other sensor may be configured to monitor another operating parameter and to trigger the sensor to be trigged only when that other operating parameter assumes a predetermined triggering property.
- sensors should no longer necessarily be instructed centrally by the signal processing device to receive them
- Such a decentrally triggered triggering can, for example, prevent a bus system used for data transmission from being permanently loaded with a data flow and / or the signal processing device having to analyze permanently transmitted data, although, for example, no relevant event has occurred at present, which includes the acquisition of operating parameters and whose transmission appears necessary Hesse.
- Decentralized triggers using additional sensors can therefore help avoid data processing bottlenecks and / or data transmission bottlenecks.

- operating parameters can act locally Accelerations to components of the passenger transport system such as an entire cabin of an elevator, a door of a cabin of an elevator or the
- Monitoring other operating parameters may include, for example, measuring locally prevailing temperatures, locally occurring noises, locally occurring electrical, magnetic or other fields, etc.
- information about electrical currents may be obtained, for example, to drive components in a passenger transportation system.

- the first sensor can preferably be selected such that it can be detected by the sensor with a technically simply designed sensor system.
- the first sensor can be selected such that it can be detected by the sensor with a technically simply designed sensor system.
- Operating parameters are selected so that it reproducing sensor data a small volume of data per measurement process (for example, less than 10 bytes or less than 2 bytes) need, so that both a corresponding data analysis and a
- the first operating parameter may be an easily measured volume of a local noise prevailing in the passenger transport system.
- the first operating parameter may be a current to a drive component in the passenger transport system or an electric or magnetic field caused thereby.
- the trigger property which is to be detected upon detection of the first operating parameter, so that the second sensor is triggered, can generally be any characteristic of the detected first operating parameter that is to be unambiguously identified.
- the trigger property may be a threshold at which
- an edge, along which the first operating parameter develops over time, or a slope of such an edge serve as a trigger property.
- the trigger property can be, for example, a volume threshold to be exceeded or undershot or a volume development increasing or decreasing with a steep edge. The presence of such a trigger property can be relatively easily detected by means of a simple sensor, for example in the form of a simple microphone.
- Operating parameters are monitored for the presence of a trigger property.
- the spectrum of a detected sound could be examined for the presence of a specific spectral component, whereby the spectral component could be typical for certain sounds, such as squeaking, for example.
- the second operating parameter to be detected may be any operating parameter that differs from the first operating parameter. It may be advantageous to select the first and second operating parameters such that the second
- Operating state of the passenger transport system can give as the first operating parameter.
- the second operating parameter can in principle be transmitted to the signal processing device in any desired manner.
- a transmission can take place via a bus system, via which in general a substantially arbitrarily large number of sensors
- the first operating parameter detected by the first sensor can be transmitted to the signal processing device in the same or a similar manner.
- a function of sensors within a passenger transport system at least partly decentralized. This can significantly reduce a lot of data to be transmitted or data to be processed.
- technically simple first sensors can be used to trigger possibly more complex second sensors or to trigger the signal processing device to process their sensor data.
- transmission of sensor data of the second operating parameter to the signal processing device and processing of this sensor data can be reduced by generating, transmitting and / or processing such sensor data only when this is done by the first sensor upon detection of the trigger property was triggered at the first operating parameter.

- the processing can only be to forward the signal to another device.
- a current sensor for example, in a car door sensor arrangement
- the current sensor is connected to the main power supply to the car door.
- the current sensor acting as the first sensor in this case can detect whether the car door is currently starting to be opened or closed due to current current signal patterns, which in this case were predetermined as a trigger characteristic. If such a trigger property is detected, a first trigger signal is output and sent to the
- Acceleration sensor and / or the microphone transmitted which act in this case as second sensors. These then begin to monitor whether the car door is accelerated in a typical for the opening or closing or if typical noises are generated. Corresponding signals are from the
- the triggering can either activate the subsequent second sensors to take measurements of the operating parameters to be detected by them, or activate processing or analysis of continuously recorded operating parameters, for example until the triggering is deactivated again or a deactivating second trigger signal is transmitted. From a signal processing device from the signals, possibly after a previous processing, to an external

- the proposed method further has
- the signal processing device can be configured to transmit signals to a remote monitoring device arranged to the passenger transport system.
- the signals transmitted to the signal processing device with respect to the second operating parameters in the signal processing device can be at least partially processed and then forwarded to an external monitoring device.
- the monitoring device can be located outside the passenger transport system, in particular outside of the passenger transport system receiving building.
- the Monitoring device to be part of a set up at a manufacturer of the passenger transport installation monitoring center. In this way, on the basis of the transmitted operating parameters in the monitoring device from a distance
- transmitting data volume or a data amount to be processed can be kept low due to the locally triggered triggering of the second sensors.
- the first sensor for triggering the second sensor can transmit a trigger signal directly to the second sensor.
- a plurality or all of the plurality of sensors may be configured to transmit to other ones of the plurality of sensors signals, in particular trigger signals.
- a triggering of a second sensor and thus a detection of the second operating parameter can be triggered by a first sensor recognizing the presence of the predetermined trigger characteristic in the first operating parameter detected by it and then transmitting a signal directly to the second sensor to triggers this.
- triggering of the second sensor does not necessarily require data transmission from the first sensor to the signal processing device. Instead, it may be sufficient for the first sensor to communicate directly with the second sensor to trigger it.
- data transmission quantities, data processing quantities and / or reaction times, ie times until the second sensor is actually triggered after the detection of a trigger property can be reduced.
- the first and the second sensor can advantageously communicate via a network or a data bus, with which they are both connected.
- the first sensor can transmit a signal representing the detected first operating parameter to the second sensor.
- the second sensor detects the presence of the predetermined trigger characteristic and generates a trigger signal in response thereto.
- the trigger signal is an internal signal within the second sensor.
- the first sensor for triggering the second sensor is a trigger signal to the first sensor for triggering the second sensor
- the first sensor does not transmit its trigger signal directly to the second sensor but to the signal processing device.
- the signal processing device can then forward this trigger signal to the second sensor.
- Constellation has the signal processing device, for example, the ability to take even influence on the triggering of the second sensor, for example, after the signal transmitted from the first sensor trigger signal has been analyzed and / or processed. While the sensors themselves are usually designed to be technically simple and in particular have no or at most a low own signal processing capability, but for example always emit the trigger signal upon reaching the trigger property, an intermediate circuit of the signal processing device can thus enable the emitted trigger signal either unfiltered to the second Forward sensor or process this in advance in the signal processing device. In this way, the signal processing device has, for example, the Possibility to compare the trigger signal with signals from other sensors and to be able to decide, for example, whether the second sensor should actually be triggered, depending on the situation.
- the second sensor is triggered for the first time as soon as the first detected by the first sensor
- Operating parameter assumes a predetermined first trigger property.
- the second sensor repeatedly detects the second operating parameter and the signal representing the detected second operating parameter is transmitted to the signal processing device in response to the first triggering until the first operating parameter detected by the first sensor assumes a predetermined second triggering property and then a second triggering signal is transmitted to the second sensor.
- the first sensor generate a first trigger signal to cause the second sensor to measure the second operating parameter, but the second sensor can be provided
- Trigger signal which causes him to stop the repeated measurement process.
- the first and the second trigger signal can be emitted in response to the detection of a first or a second trigger property.
- the two trigger properties can be identical, that is to say, the first trigger signal is triggered the first time the trigger characteristic is detected, and the second trigger signal is then triggered on the subsequent detection of the same trigger property.
- the two triggering properties are different from each other.
- the first and second trigger characteristics may be two different thresholds with respect to the observed first operating parameter.
- the first trigger signal may be generated when a detected volume exceeds a first threshold.
- the second trigger signal can be generated when the detected volume falls below the first or a second threshold again.
- the first sensor can be used to decentrally control or trigger a function of the second sensor. In particular, a start and an end of a measuring operation of the second sensor can be triggered.
- a sensor repeatedly records the operating parameter to be detected by it over a period of time and then determines the trigger characteristic for subsequent detection operations.
- a certain learning function can be implemented in one of the sensors of the passenger transportation system.
- the learning function can be used to trigger the property monitored by the sensor
- the sensor can set or set this trigger property as part of its learning function. For this purpose, the sensor can first observe the operating parameter to be detected by it over a certain period of time, i. capture the operating parameter repeatedly, and then set the trigger property based on this observation. Due to this learning function, the sensor can at least partially adapt its properties to actually prevailing conditions.
- a microphone used as the first sensor can first observe ambient noise over a certain period of time. If during this period of time it can be assumed that the passenger transportation system is in the normal state, one or more threshold values can then be defined based on the observed maximum volume noise, which can be defined as a trigger property. Occurs during later operation of the first sensor the case that clearly noisy noises are detected, this can then lead to the triggering of a second sensor. In this case, it can be assumed, for example, that the particularly loud noises were generated due to a disturbance such as, for example, a squeaking of components of the passenger transport system rubbing against one another. This can be interpreted as an occasion to measure second operating parameters which, for example, can allow a closer inference to the disturbance.
- a disturbance such as, for example, a squeaking of components of the passenger transport system rubbing against one another. This can be interpreted as an occasion to measure second operating parameters which, for example, can allow a closer inference to the disturbance.
- the sensors may be configured to detect only one type of operating parameter.
- the sensors included in the device for the passenger transportation system may be relatively simple sensors that merely need to be configured to measure a single type of operating parameter.
- their costs can be reduced and / or their reliability can be improved.
- complex-acting sensor arrangements can be created by means of which various operating parameters can be detected and monitored in accordance with the situation.

- the second sensor instead of trigger signals T2 n , T2 W and T2f. also continuously transmit a signal reproducing the detected second operating parameter to further sensors 41, which then evaluate it as described.
- Elevator installation 2 will be explained.
- a current sensor, an acceleration sensor and a microphone are installed in the car door sensor assembly 29.
- the current sensor is connected to the main power supply to the
- the current sensor acting as the first sensor 37 in this case can detect whether the car door 13 is currently starting to be opened or closed due to current current signal patterns, which in this case were predetermined as a trigger characteristic. If such a trigger characteristic is detected, a first trigger signal is output and transmitted to the acceleration sensor and / or the microphone, which act as second sensors 39 in this case. These then begin to monitor whether the car door 13 is accelerated in a typical for the opening or closing or whether typical noises are generated. Corresponding signals are transmitted from the acceleration sensor and / or the microphone to the signal processing device 35.
- the triggering may either activate the subsequent second sensors 39 to take measurements of the operating parameters to be detected by them or activate processing or analysis of continuously received operating parameters, for example until the triggering is deactivated again or a deactivating second trigger signal is transmitted. From the signal processing device 35 from the signals, possibly after a previous processing, to the external
- Monitoring device 36 transmitted. Should be atypical in the signals
- Operating parameters are detected, for example, too slow Accelerating the car door or indicate unusual noise, this can be detected as a malfunction of the car door 13.
- a first sensor 37 in the form of a current sensor for example, recognize if a
- Main power supply to a drive unit increases significantly, for example, to go from a crawl to a fast drive.
- the first sensor 37 may then trigger one or more second sensors 39 to measure, for example, accelerations or noises that can be used to track whether the transition to faster travel is regular or, for example, delays or unusual noises due to malfunction comes.
- Device-generated trigger signals can be made available to all sensors in a network. Further, multiple triggers and / or sensor signals may be combined to fuse, for example, the functions of multiple sensors.
- signals already measured by sensors can be reused within a decentralized sensor network. This can improve performance, reliability and / or efficiency within the sensor network.
- simple sensors can be combined with one another in order to be able to provide more complex information in the manner of a sensor fusion.
- a signal segmentation can be effected by sensor signals, preferably without connection to, for example, a control of the passenger transport system. Overall, operating parameters can be recorded exclusively or, above all, during relevant times or relevant events.
- the solution proposed herein may make it possible to roast existing passenger transport systems with sensors that can detect specific operating conditions, without a connection needs to be established, for example, to control the passenger transport system. Furthermore, a number of Wiring be reduced by the reuse of signals and trigger signals within the sensor network, in particular due to the unnecessary connection to the control of the passenger transport system. Ultimately, in particular, a cost reduction can be achieved, for example by the sensor fusion using multiple simple sensors instead of a complex sensor.
- the provision of decentralized triggering of individual sensors 39, 41 by other sensors 37, 39 reduces a data processing quantity and / or a data transmission quantity, reduces a need for wiring, and achieves complex sensor functions with the aid of simple sensors 37, 39, 41 cooperating with each other, which is especially true when retrofitting existing passenger transport systems 1 may be advantageous.
