Definitions
- Sensors in buildings and systems are designed to detect fires or poisonous vapors, measure material loads in load-bearing building parts or system components, record the climatic conditions in the room, locate sound, determine the presence of people or locate people, materials or devices.
- the object of the invention is to enable the construction of a sensor network which avoids the disadvantages described.
- a sensor node has means for distance measurement, sensor means for measuring a sensor measured value in addition to the distance, and means for wireless communication. indication of the measured distance and the sensor measured value.
- the means for communication are in particular means for communicating with a further sensor node.
- the means for communication preferably have a WLAN module.
- the means for distance measurement advantageously measure the distance over the transit time of a signal, in particular a high-frequency signal.
- a signal in particular a high-frequency signal.
- they contain, for example, a radar module.
- they can have special filtering or learning methods, in particular in the form of a Kalman filter.
- a sensor network consists in particular of a multiplicity of sensor nodes according to one of the aforementioned types. This enables a self-organizing sensor network to be used to monitor buildings and systems and to navigate maintenance, security and rescue workers.
- the means for measuring the distance of the individual sensor nodes are preferably used and coordinated such that the position of the individual sensor nodes is determined via the combined measurement of the distances between the sensor nodes.
- At least one sensor node preferably has storage means for storing its absolute position.
- the sensor node can then be brought to several locations, with its absolute position being stored in its storage means.
- the sensor network then takes the absolute position of the sensor node at each of these multiple locations and can thus clearly position itself in three-dimensional space.
- a plurality of sensor nodes have storage means for storing their absolute position and the plurality of sensor nodes are positioned at different positions.
- the means for communicating the sensor nodes are preferably set up in such a way that sensor nodes in the sensor network can communicate with distant sensor nodes by forwarding the communication via neighboring sensor nodes. This is done in particular via position-based multi-hop routing.
- the sensor network is advantageously set up in such a way that the sensor measured values of the sensor nodes and the positions of the sensor nodes can be queried.
- the sensor network works as a self-organizing sensor network without a central authority.
- a sensor network according to one of the previously described versions is used to measure the sensor measurement values.
- Advantageous refinements of the method result analogously to the advantageous refinements of the sensor network and vice versa.
- FIG. 1 shows a sensor node.
- each sensor node 1 contains a housing 2, a power supply 3, for example in the form of a battery or an accumulator, a main computing unit 4, means 5 for communication with one or more further sensor nodes, the means 5 for communication being in the form of a radio module, means 6 for distance measurement in the form of a radar module and sensor means 7 for measuring a sensor measured value in addition to the distance.
- the power supply 3, the main computing unit 4, the means 5 for communication, the means 6 for distance measurement and the sensor means 7 are located in the housing 2.
- the housing 2 and thus the sensor node 1 also have connections 8 for one or more Antennas, a connector 9 for power supply and a connector 10 for external devices for data exchange, eg via Ethernet.
- the means 5 for communication in the form of the radio module allow the communication of the sensor node 1 with neighboring sensor nodes, for example via the WLAN standard. Position-based multi-hop routing can also be used to reach remote sensor nodes.
- the means 6 for distance measurement in the form of the radar module carry out distance measurements to neighboring sensor nodes.
- suitable filtering and / or learning methods such as a Kalman filter, the sensors can be localized in an internal coordinate system.
- the internal coordinate system can be synchronized with that of an external map of the environment.
- the sensor means 7 in the form of the sensor module deliver various sensor measured values. Together with sensor measurement values of neighboring sensor nodes are used to train a local regression model that allows spatial or even spatiotemporal profiles of sensor measurements to be created. These profiles can be queried by external applications. These applications can be, for example, visualization methods on portable computers, each of which is connected to a sensor node.
- the sensor nodes require little effort for the installation and operation of a sensor network.
- the sensor network is able to precisely localize individual, in particular mobile, sensor nodes. It scales well, which means that it can be easily expanded with additional sensor nodes and can therefore increase coverage or resolution.
- the functionality of the sensor network is only noticeably impaired by the failure of many sensor nodes, since the communication can switch to other routes and the sensor information is stored distributed in the network.
