Definitions
- the present invention relates to an apparatus and a method for determining a state of an object to be monitored.
- Sensors for condition monitoring of doors and windows are known. These sensors are usually designed in two parts. A first part of the sensor consists of a permanent magnet. A second part of the sensor has a
- Magnetic sensor for example, a reed contact
- Permanent magnet in the first part of the sensor can be opened or closed.
- a part of the sensor on the movable frame of the monitored window or the door to be monitored must be attached and the other part of the sensor must au outside the movable frame, for example, on the wall, are attached. If the door or the window is closed, then the reed contact is triggered by the magnetic field of the permanent magnet. If the door or the window is opened, the reed contact is not triggered.
- German patent application DE 103 35 126 A1 discloses a device for condition monitoring of an object, in which a reed contact by a
- the device also has a transmitting unit, by which the detected state of the object or a
- the present invention provides a device for determining a state of an object to be monitored, comprising a magnetometer, which is designed to detect a magnetic field and to generate a first measured value
- an acceleration sensor configured to detect an acceleration and to provide a second measured value as a function of the detected acceleration
- a processing device configured to detect a state of the object to be monitored using the state of the magnetometer and / or the magnetometer
- Accelerometer provided readings from a plurality of
- the present invention provides a method of detecting a state of an object, comprising the steps of detecting a magnetic field and providing a first measurement value corresponding to the magnetic field; detecting an acceleration of the object to be monitored and providing a second measured value corresponding to the detected acceleration; and determining a state of the object to be monitored from a plurality of predetermined states using the first measured value corresponding to the detected magnetic field and / or to the detected one
- the present invention is based on the idea of a device for
- Components required for such condition monitoring are arranged in a common housing.
- measurements are taken from sensors which can determine a movement and / or a change in position in space without additional aids, such as additional permanent magnets or the like.
- the measured values of several such sensors are fused together.
- the device and the method for determining a state of an object further pursue the approach that the monitoring object can only be in a plurality of previously defined states.
- the monitoring object can only be in a plurality of previously defined states.
- one of these predetermined states may be new State of the object to be selected.
- Determination of a state can be further increased by each of the currently determined state of the object is included in the determination of the new state in the determination of a new state.
- the possibility of state transitions from a current state to a new state can also be defined and restricted.
- State transitions are defined. In this way, the reliability of the state determination can be improved because unauthorized state transitions are excluded from the outset.
- the device further comprises a memory which is designed to store a state determined by the processing device and measurements corresponding to the specific state of the object from the magnetometer and / or the acceleration sensor.
- This stored data can not only be stored for logging purposes, but also serve in particular as data for a successive calibration of the condition monitoring.
- the stored specific states and the corresponding measured values can for example be limited to a predetermined number of data sets. In this case, preferably the oldest previously stored data record can be deleted when a further data record is added.
- the processing device determines the state of the object to be monitored using the states stored in the memory and the corresponding measured values. By using these data stored in the memory, the determination of the states of the object to be monitored can be continuously improved. In particular, this also makes it possible to permanently adapt and re-call state monitoring to changing external influences. Thus, the condition monitor can operate correctly even if the device is placed again on the object to be monitored or the device is placed on another object to be monitored.
- the apparatus further includes a communication interface configured to transmit the condition determined by the processing device. Through this communication interface, the specific states and state changes can be passed. For example, it is possible to transmit the data of a specific state to a central building surveillance.
- the communication interface transmits that of the
- Processing device certain state wirelessly.
- Data transmission allows, in particular for moving objects, a very convenient transfer of the determined status data.
- the magnetometer and / or the acceleration sensor can be deactivated by the processing device.
- the processing device for example, a
- State change of the object are initially monitored by only one sensor. As soon as this one sensor detects a possible state change, the further sensor can then be activated by the processing device. In this way, on the one hand a particularly energy-saving monitoring of the object is possible, while at the same time a reliable determination of changes in state can be performed by the demand-oriented activation of other sensors.
- the monitoring object is a door or a window.
- the predetermined states include the states opened, closed and tilted. Doors and windows are objects which, due to their clearly defined number of possible states, are particularly well suited for
- condition monitoring according to the invention are suitable.
- the step for determining a state for each predetermined state calculates a probability and then determines the state with the largest one
- the present invention further comprises a building management system having a device according to the invention for determining a state of an object to be monitored.
- Fig. 1 is a schematic representation of a block diagram of an apparatus for
- FIG. 2 shows a schematic representation of a device for determining a state according to a further embodiment on an opened window
- FIG. 3 shows a schematic representation of a device for determining a state according to a further embodiment on a tilted window
- FIG. 4 shows a schematic representation of a method for determining a state, such as another embodiment of the present invention
- Fig. 1 shows a schematic representation of a block diagram of a device 1 for determining a state of an object to be monitored according to a
- the device 1 comprises a magnetometer 1 1 and an acceleration sensor 12, which are connected to a processing device 13.
- This processing device 13 is further provided with a memory 14 and a
- the magnetometer 11 is preferably a 3-axis magnetometer. Such a magnetometer detects a magnetic field in all three spatial directions. In particular, such a magnetometer is able to detect changes in the magnetic field in one or more spatial directions separately.
- Magnetometer 1 1 gives its measurement results in the form of measurement signals to the processing device 13 on.
- the magnetometer 1 1 can thus by
- the acceleration sensor 12 is also preferably a 3-axis acceleration sensor that can detect both positive and negative accelerations in all three spatial directions.
- the acceleration sensor 12 also outputs its measurement results in the form of measurement signals to the
- Processing device 13 on.
- the processing device 13 can thereby deactivate one of the two sensors 11 or 12 in a standby state. For example, the first
- Magnetometer 1 1 are disabled and the object to be monitored
- the acceleration sensor 12 can be activated after a movement of the object to be monitored has been detected by the magnetometer 11, in order to evaluate the measuring signals of the acceleration sensor 12 together with the measuring signals of the magnetometer 11.
- the processing device 13 receives measuring signals from the magnetometer 11 and / or the acceleration sensor 12 which indicate a movement of the object to be monitored, these signals are evaluated by the processing device 13 and then a possible new state of the object to be monitored is determined.
- Acceleration sensor 12 evaluated together.
- the processing device 13 analyzes the measurement signals provided by the magnetometer 11 and the acceleration sensor 12 and then determines from a plurality of predetermined possible states of the object to be monitored using the provided measurement signals, a possible new state of the object to be monitored.
- the object to be monitored is a window
- this object can normally have three possible states: closed, opened or tilted.
- FIG. 3 further shows a window 2 in a tilted state.
- the window 2 is tilted on further hinges (also not shown) about the X-axis.
- the window shown in FIGS. 2 and 3 can therefore assume the three states of being opened, closed or tilted, it not being possible to move from each state directly to any other state. If the window 2 is in an open state, for example, then it is not possible to switch directly to the tilted state. Rather, it is imperative that the window 2 is closed before. Likewise, conversely, the transition from the tilted state is possible only in the closed state. Only then can the window 2 be opened.
- the processing device 13 takes into account these additional constraints by which allowed or not allowed state transitions are defined.
- Processing device 13 will therefore in a known current state of the object to be monitored 2 using the provided measurement signals only determine those new states, which are also allowed in accordance with the predetermined constraints. Unauthorized state transitions, which rule out one or more of the predetermined states on the basis of the currently determined state, mean that the corresponding excluded predefined states can not be determined as new states.
- the processing device 13 can for determining the new states of the monitoring object 2 for all predetermined states, preferably at least for all allowed predetermined new states based on the provided measurement signals each calculate a probability.
- Calculation of the probabilities for the predetermined states can be analyzed, for example, the waveforms of magnetometer 1 1 and / or acceleration sensor 12 during a period of time.
- the signal curves for all spatial directions can be separated or if necessary also analyzed together. Also, an evaluation of the amounts of the waveforms for all spatial directions together or separately is possible.
- the processing device 13 can also only one
- the processing device 13 can directly evaluate the measurement signals from the magnetometer 11 and the acceleration sensor 12 and then determine, based on predetermined rules, one in the predetermined states of the object 2 to be monitored.
- the previous measured values of magnetometer 11 and acceleration sensor 12 can be stored in the storage device 14.
- the processing device 13 can read out these stored measured values and the corresponding state of the object from the memory device 14 and use them to determine a new state of the object.
- the measured values or signal profiles currently provided by magnetometer 11 and acceleration sensor 12 can be stored with previously stored data
- monitoring object 2 are stored a matrix X with measured values, as shown in the following formula:
- a xi , A yi and A zi are respectively the measured values of the acceleration sensor 12 and M xi , M yi and M zi are respectively the measured values of the magnetometer 11 in the respective spatial directions x, y and z.
- the counter i denotes the individual measurements.
- state stands for the individual predetermined states that the
- a separate matrix X (state) is created for each predetermined state of the object 2 to be monitored.
- the device 1 can adapt itself automatically to the changed framework conditions.
- a metallic body placed nearby for example a cabinet, would bring about changes in the earth's magnetic field detected by the magnetometer 11. Due to the successive automatic calibration, this disturbance can be compensated very quickly. Also possibly occurring
- the states of the object 2 to be monitored determined by the processing device 13 can be forwarded to a communication interface 15.
- the communication interface 15 then transmits the determined states or a determined state change to a suitable receiver.
- a wired data transmission is possible.

- a magnetic field preferably the earth's magnetic field, detected and one to the detected
- step 120 a
- a state of the monitoring object is selected from a plurality of
- the step 130 may preferably have a for each of the predetermined states
