Definitions
- the invention relates to a method for operating a sensor arrangement for detecting a person in a usage area of a sanitary facility, a sensor arrangement for detecting a person in a usage area of a sanitary facility, and a sanitary facility with such a sensor arrangement.
- Presence sensors with a comparatively large range are usually used to monitor the presence of one or more people in a usage area of the sanitary fitting over as full an area as possible.
- the large range often comes at the expense of the accuracy of these sensors.
- Increasingly precise measurements are required, in particular to implement advantageous functions such as automatic flushing when a person moves away from the fitting, which cannot always be implemented with long-range sensors.
- at least short-range sensors are also increasingly being installed in sanitary fittings.
- ToF Time of Flight
- ToF Time of Flight
- a method for operating a sensor arrangement for detecting a person in a usage area of a sanitary facility contributes to this, at least comprising the following steps: a) Switching on a first sensor of the sensor arrangement if a second sensor of the sensor arrangement that differs from the first sensor indicates the presence of at least a person is detected in the vicinity of the sanitary facility (in particular in the area of use), the switching on comprising establishing a previously completely interrupted power supply to the first sensor and the first sensor being a ToF sensor; b) detecting at least one piece of distance information about the spatial distance between the person and the sanitary facility by means of the first sensor, with a transit time measurement of a signal emitted by the first sensor being carried out; c) switching off the first sensor when the presence of at least one person in the vicinity of the sanitary facility (in particular in the area of use) is no longer detected by the first sensor and/or the second sensor in particular, the switching off leading to a complete interruption of the power supply includes the first sensor.
- steps a), b) and c) can be carried out, for example, at least once and/or repeatedly in the order given.
- the method can be carried out, for example, by means of a sensor arrangement that is also described here.
- the method is used to identify a person in the usage area of the sanitary facility.
- the method can contribute to or be carried out for (electronic) control, in particular triggering or activating (a water release) of the sanitary facility.
- the sanitary facility can be, for example, a water fitting, e.g. B. in the manner of a faucet, a shower, a bathtub, etc. Furthermore, the sanitary facility can be, for example, a toilet or WC, a bidet and/or a urinal or a fitting for this.
- the area of use means in particular a (predetermined) surrounding area on or around the sanitary facility, when a person (e.g. a hand) enters the sanitary facility and/or (a water supply) is activated.
- the sensor arrangement or the first sensor and/or the second sensor is (or are) applied to or on the sanitary facility in such a way that its detection field roughly corresponds to the predetermined area of use or at least partially covers it.
- the sensor arrangement can include the first sensor and the second sensor, for example in the manner of a hybrid sensor.
- the first sensor and the second sensor can form a hybrid sensor of the sensor arrangement.
- the term “hybrid sensor” means in particular that two different sensor technologies are used.
- the first sensor is suitable for carrying out a distance measurement.
- the second sensor can only be suitable for detecting the presence of an object, such as a person, in the usage area.
- the first sensor and the second sensor can work according to physically different measurement principles.
- the ToF (Time of Flight) sensor advantageously enables contactless detection of the presence or measurement of the distance to physical objects and people.
- the ToF sensor can measure the distance to a target object by timing the circulation of photons on their way from the sensor to the object or person and back (time-of-flight measurement).
- the ToF sensor can be designed with vertical-cavity surface-emitting lasers (VCSEL) and/or arrays with single-photon avalanche photodiodes (SPAD: Single Photon Avalanche Photodiode).
- VCSEL vertical-cavity surface-emitting lasers
- SPAD Single Photon Avalanche Photodiode
- the ToF sensor can realize multiple, for example three, distance mode functions, for example a near, medium and short range mode.
- the ToF sensor can, for example, carry out distance measurements with a resolution of 1 mm [millimetre] and, in particular, report this to the control device via a digital l 2 C interface, which can also serve as a control connection for the sensors.
- the ToF sensor can be a ToF laser sensor.
- the ToF sensor and/or the sensor arrangement can have a viewing window, which can preferably filter out light with specific wavelengths or other wavelengths (than the laser beams).
- the ToF sensor can also be used to carry out several distance or distance measurements (carried out in chronological succession) for the purpose of tracking a movement of a person in the usage area or out of the usage area, for example to leave a urinal or a toilet trigger a flush.
- the method advantageously contributes to the fact that a ToF measurement is only carried out when an object is located in the usage area (capture or detection area). As a result, the (total) energy requirement of the sensor arrangement can advantageously be reduced.
- the detection of whether something is in the detection area takes place in particular with a (second) sensor, which advantageously requires little energy.
- the ToF sensor can be switched off completely using suitable means (power off).
- a control device can use an additional sensor to check whether something is in the detection area. As soon as an object is detected in the detection area, the ToF sensor can be switched on and a distance measurement can be carried out. As soon as the control device has recognized that the detection area has been left, the ToF sensor can be switched off. Leaving the detection area can be detected both with the ToF sensor and with the additional sensor.
- the second sensor has a lower electrical power consumption than the first sensor. Furthermore, the second sensor can have a greater range than the first sensor. In addition, the first sensor can have a greater measurement accuracy than the second sensor.
- the second sensor can be an ultrasonic sensor or an infrared sensor.
- the second sensor is preferably an infrared sensor.
- the the second sensor can be arranged in particular independently of the first sensor (ToF sensor).
- the first sensor and the second sensor can be arranged directly next to one another.
- the first sensor and the second sensor can be arranged in a common housing.
- the first sensor is connected to an electrical energy store of the sanitary facility in order to establish the power supply.
- the electrical energy store can, for example, comprise at least one electrical battery and/or at least one electrical accumulator.
- the complete interruption of the power supply differs from a transfer to a “standby” mode, in which a sensor would still consume electrical energy or current.
- the first sensor is advantageously always actuated here via the switches or the control device.
- the transistor can advantageously be switched through by a simple binary signal and the first sensor can be supplied with current again.
- a sensor arrangement for detecting a person in a usage area of a sanitary facility at least comprising:
- a first sensor which is a ToF sensor, for detecting at least one piece of distance information about a spatial distance between a person and the sanitary facility;
- An electronic switch for making or interrupting a power supply from an electrical energy storage device to the first sensor
- a control device for actuating the electronic switch depending on whether the presence of at least one person in the vicinity of the sanitary facility is detected by means of the second sensor.
- the sensor arrangement can advantageously be set up to carry out a method described here.
- a sanitary facility with a sensor arrangement described here is proposed.
- Fig. 1 an exemplary sequence of a method presented here
- FIGS. 2, 3 schematically shows an exemplary sequence of a method presented here.
- the method is used to operate a sensor arrangement 1 for detecting a person 8 in a usage area 2 of a sanitary facility 3 (cf. FIGS. 2, 3).
- the sequence of steps a), b) and c) represented by blocks 110, 120 and 130 is exemplary and can be run through at least once in the sequence represented in order to carry out the method.
- a first sensor 4 of the sensor arrangement 1 is switched on if a second sensor 5 of the sensor arrangement 1, which differs from the first sensor 4, detects the presence of at least one person 8 in the vicinity of the sanitary facility 3, with the Turn on a make a previously complete comprises interrupted power supply to the first sensor 4 and wherein the first sensor 4 is a ToF sensor.
- the first sensor 4 is a ToF sensor.
- step b at least one piece of distance information about the spatial distance between the person 8 and the sanitary facility 3 is detected by the first sensor 4, with a transit time measurement of a signal emitted by the first sensor 4 being carried out.
- the first sensor 4 is switched off in block 130 if the presence of at least one person 8 in the vicinity of the sanitary facility 3 is no longer detected, the switch-off comprising a complete interruption of the power supply to the first sensor 4 .
- the sanitary facility 3 is designed in the manner of a sanitary fitting which, for example, can discharge water into a washbasin positioned in front of it.
- the sensor arrangement 1 comprises a first sensor 4, which is a ToF (Time of Flight) Sensor is, for detecting at least one piece of distance information about a spatial distance between a person 8 and the sanitary facility 3.
- the sensor arrangement 1 further comprises a second sensor 5, which differs from the first sensor 4, for detecting the presence of at least one person 8 in the vicinity of the sanitary facility 3.
- the sensor arrangement 1 further comprises an electronic switch 10 for producing or interrupting a power supply from an electrical energy store 7 to the first sensor 4.
- the sensor arrangement 1 can be designed in the form of a hybrid sensor, in which a second sensor 5 represents an additional sensor to a first (ToF) sensor 4, which requires much less energy than the first sensor 4 (main sensor). .
- the additional sensor is used here in particular to switch on the ToF sensor for a measurement only when required. During the rest of the time, the ToF sensor remains switched off (i.e. completely de-energized or in "power off”).
- the (total) energy requirement of the sensor arrangement 1 or of the hybrid sensor can be advantageously reduced as a result.
