Description

The invention relates to a method for detecting particle contamination in the interior of a building by means of a detection device and to an arrangement.Corresponding methods for detecting particle contamination in the interior of a building by means of a detection device are fundamentally known from the prior art. Thus, detection devices for detecting particle contamination are known, which, placed in a building interior, can detect the particle contamination there.WO 2018 / 078181 A1 discloses a data recording arrangement for creating a work plan.EP 1 856 453 B1 discloses dynamic control of dilution aeration in critical fitting environments.US 2015 / 0077737 A1 discloses a system and a method for monitoring an environment.DE 10 2017 003 581 A1 discloses a process for the preparation of lincomycin 3-monoacylate compounds.The object of the invention is to specify a method which reliably detects, in particular in view of a simple and rapid and cost-effective measure, particle contamination, in particular area-dependent, in the interior of a building.The object is achieved by the subject matters of the independent claims. The claims dependent thereon relate to possible embodiments.The invention relates to a method for detecting particle contamination inside a building by means of a detection device. The method is characterized in that a first detection device is arranged at a first location in the interior of the building, wherein a first detection information describing a particle contamination in the building is generated via the first detection device, and a further detection device is arranged at at least one further location in the interior of the building, wherein a further detection information describing a particle contamination in the building is generated via the further detection device, and the detection information is transmitted to a central processing unit in order to derive a particle contamination information from the combined detection information. In this case, derivation means relating and / or calculating, i.e. a generation of particle contamination information takes place as a function of the combined, for example differently weighted, detection information. By simultaneously detecting the particle concentration at a first and at a further location in the interior of the building, it is possible to obtain more accurate and / or plausibility checked particle contamination information about the particle contamination in the interior of the building and / or at or on an object located at least temporarily in the interior of the building. The detection device can be configured, for example, such that it enables detection of articles, in particular nanoparticles.The particles can comprise carbon black and / or fine dust and / or ultra-fine dust (i.e. particles with a thermodynamic diameter of less than 0.1 μm) and / or an aerosol. For example, the particles detectable with the detection device can have an aerodynamic diameter of 5 μm as the separating grain diameter. Alternatively or additionally, the detection device can be configured to detect particles which correspond to the policy standard PM 10 and / or PM 2,5 and / or to enable the computing unit to calculate or output particles relating to PM 10 and / or PM 2,5 from the detection information determined via the detection devices.In other words, the detection device can be configured to detect dirt in the air or within the gas located in the interior of the building. For example, the building is used as a painting shop, wherein contaminants or particles located in the air can have a negative effect on the painting process, for example in that suspended particles or particles are bound by the paint material to the permissible surface of the object to be painted during painting and in the process adversely affect the layer formation of the paint material during the painting process. Alternatively or additionally, it may also prove to be advantageous in other types of manufacturing and / or assembly processes in the context of an industrial or laboratory-type application if an, in particular area-dependent, detection of the particle contamination is carried out in the interior of a building. For example, this can be advantageous in rooms for manufacturing wafers and / or in assembly halls for assembling lead-free bearings (e.g. in motor technology), since these processes are sensitive to contamination and the manufacturing and / or assembly result can be adversely affected by suspended particles and in particular by particles.With the detection devices used, for example, a location-dependent actual state of the number of particles or of the quantity of particles (volume and / or weight proportion of particles per unit volume) and / or of the type of particles (e.g. composition and / or shape of the particles) can take place within the interior of a building. The detected actual state can be matched to a setpoint state stored in a storage device by a comparison means (e.g. a microcontroller and / or a computer program) and, if appropriate, any action recommendations and / or countermeasures can be output or executed automatically or after confirmation of an operator.From the detection of the particle contamination in the interior of a building, in particular a region-dependent detection of the particle contamination, indirect information can also be derived, such as, for example, whether a closable opening of the building was or has been opened or closed or partially opened at specific times. For example, by the area- or location-dependent detection of the particle contamination, a particle contamination change typical of an open / closed / partially opened state of a closable opening of the building can be detected and an opening state and / or a type or scope of an opening state of a closable opening of the building can be derived or detected therefrom. In a specific embodiment, this can be done in that, by opening a window or a gate of an industrial hall by the generated air flow connected thereto, a change in the particle contamination typical for this purpose, i.e. in particular the particle type and / or the particle quantity, can be detected at defined locations in the interior of the building and the open state can be deduced therefrom at a specific point in time.It is possible for the first and / or the at least one further detection device to detect, for example, the temperature and / or the air humidity and / or flow speed and / or flow direction and / or particle quantity and / or particle type of a gas or gas mixture flowing into the interior of the building, in particular a gas or gas mixture containing a number of particles to be detected, and to generate detection information comprising temperature and / or air humidity and / or flow speed and / or flow direction and / or particle quantity and / or particle type information. Preferably, the temperature and / or air humidity and / or flow speed and / or flow direction and / or particle quantity and / or particle type information is taken into account for generating the particle contamination information.The temperature and / or air humidity and / or flow speed and / or flow direction information can alternatively or additionally also be used to generate a recommendation for action and / or a control signal for controlling a device for influencing the particle contamination in the interior of the building. The amount of particles can be present, for example, as a particle concentration, in particular comprising taking account of a particle type. A temperature and / or air humidity and / or flow speed and / or flow direction can also be used to determine a calculation and / or determination of a particle quantity and / or particle concentration and / or a particle type at a location (e.g. an intermediate region) different from the specific locations of the detection devices. For example, a particle contamination of a location or intermediate region situated between two detection devices can be determined or derived on the basis of the determined particle contamination or the particle quantity and / or particle type at the locations of the detection devices and additionally taking into account the flow speed and / or the flow direction and / or temperature and / or air humidity at the locations of the detection devices.The first piece of detection information of the first detection device can describe, for example, measurement value information of a particle quantity (in particular including a particle type) at the first location and a further piece of detection information of the at least one further detection device can describe measurement value information of a particle quantity (in particular including a particle type) at the at least one further location. As a result, the at least two items of detection information provide location-specific information about the particle quantity and / or particle type.The particle contamination information preferably comprises an assignment of the determined measured value information to the respective locations of the acquisition of these measured values. The measured value information can thus be present as location-specific information or information assigned to a location within the particle contamination information. It is thus possible for particle contamination information to comprise two- or three-dimensional information about the amount of particles and / or type of particles resolved onto the spatial region, i.e. depending on the region. In a two- or three-dimensional representation or data collection, the particle quantity and / or the particle type can be resolved or indicated via the two- and / or three-dimensional spatial distribution of the particles. At least one alternative or additional dimension of the particle contamination information (or of the particle contamination information data record) can also comprise time information. Linking of a measurement value information to a location and / or time information can be effected, for example, within the detection device, so that the detection information transmitted from the detection device to a central processing unit already contains at least partially, in particular completely, a location and / or time aspect.Alternatively or additionally, for example, a first piece of detection information of the first detection device can describe a piece of measurement value information of the temperature and / or of the air humidity and / or of the flow speed and / or of the flow direction at the first location, and a further piece of detection information of the further detection device can describe a piece of measurement value information of the temperature and / or of the air humidity and / or of the flow speed and / or of the flow direction at the further location. For example, the detection information of the at least two, in particular all, detection devices contains a similar, preferably identical, type of measurement value information (i.e. e.g. temperature and / or air humidity and / or flow speed and / or flow direction). The at least one piece of measured value information recorded by the recording device can relate, for example, to a gas or gas-particle mixture passed through a measuring range of the respective recording device. The particle contamination information preferably comprises an assignment of the determined measured value information to the locations of the acquisition of these values or measured values.It can prove to be advantageous if an assignment or a linking of the at least one piece of detection information, in particular of the detected measurement value information, to a piece of time information describing the time of the detection of the detection information, in particular of the measurement value information, takes place. In this case, the particle contamination information item can comprise an assignment of the detection information item, in particular a temperature and / or air humidity and / or flow speed and / or flow direction and / or particle quantity and / or particle type information item, to the time information item. The time information can be generated, for example, in the detection device and / or in the computing unit. The assignment of the time information to a measurement value information can be generated in the detection device and / or a computing unit. It is thus possible for the measured value information or the at least one ascertained measured value of an acquisition device within this acquisition device to be assigned to time information or to be provided with a time stamp. Consequently, this time-measured value information pair can be transmitted to a higher-order arithmetic unit. In the course of the assignment of a time value to measured value information determined by the detection devices, it may prove to be advantageous if synchronization of the time elements or of the means of the respective detection devices that determine the time values are indirectly or directly matched to one another and / or synchronized.In an optional embodiment, it can be provided that at least one piece of measured value information and / or one piece of time information and / or one piece of location information is output or can be output in information forming a static and / or a dynamic representation. For example, in a dynamic representation model, the location-specific particle contamination or the change in the location-dependent particle contamination can be represented over a temporal profile.It is possible that at least partial, in particular complete, evaluation of detection information of at least two detection devices takes place by or by means of the computing unit, wherein measurement value information, location information and time information of the respective measurement values are taken into account in order to generate particle contamination information.In addition, the computing unit can calculate or derive a value of the particle contamination or a fictitious measured value representative of these intermediate locations for locations or areas between the specific measurement locations of the detection devices. This makes it possible to achieve the effect that, by means of the fictitious or calculated particle contamination values of the intermediate locations and the particle contamination values directly determined at the locations of the detection device, it is possible to provide location-dependent particle contamination information which is at least partially, in particular completely, continuous or without gaps. In this case, in particular in addition to the particle quantity and / or particle type, temperature and / or flow speed and / or flow direction and / or air humidity can also be used in order to determine the fictitious particle contamination values for the intermediate locations or intermediate regions. Thus, in particular, the flow speed and / or the flow direction and the air humidity can be used to perform an estimation of the particle quantity and / or the particle type at intermediate locations, starting from the particle quantity and / or the particle type at the locations having the detection device. By taking into account the detected flow direction and flow speed (e.g. also the volume flow) at the measurement sites (the sites of the detection devices), for example a weighting of the detection information of the respective detection devices, which weighting is dependent on the flow direction and / or flow speed, for deriving at least one piece of particle information of an intermediate site can lead to good results for the particle contamination at this intermediate site.The particle contamination information describes information about at least the quantity and / or type of particles at at least one fixed reference location in the interior of the building and / or about at least one quantity and / or type of particles at at least one variable reference location in the interior of the building. The particle contamination information preferably describes an, in particular statistical, quantity of particles in or at the reference location.The particle contamination information can relate, for example, to an absolute quantity or a relative quantity of particles, in particular for a fixed or variable location. The absolute quantity of particles can relate, for example, as the number of particles located at a static and / or variable location. For example, the particle contamination information may indicate that a certain amount of particles is present at a fixed location inside the building. Alternatively or additionally, the particle contamination information can indicate that a specific amount of particles has added or remained constant or has decreased at a fixed location in the interior of the building over a defined period of time (e.g. after an air draft cleaning for the relevant location).A variable location or reference location can be understood to mean, for example, an object moved at least temporarily in the interior of the building. For example, the particles which are deposited on the building or are released from the building at least temporarily, in particular during its entire whereabouts, can be ascertained or output via the particle contamination information. The type and / or the distribution of particles located on the object or deposited on this object and / or dissolved by this object can also comprise the particle contamination information as content.The variable reference location is assigned to a reference object located at defined locations in the interior of the building at defined times, wherein the particle contamination information of the reference object is generated by taking into account acquisition information, in particular measurement value information, of defined locations at defined times. In other words, information about the locations in time and / or about the type of movement of an object in the interior of a building enables the detection information determined from the detection devices to be analyzed or used in time and location in such a way that a change and / or a remaining constant of particle contamination of an object moved in the interior of the building can be displayed therefrom or can be obtained as new information.In an optional development of the invention, the detection information can be used for a plurality of objects moved in the interior of the building. This means, for example, that a first piece of detection information is taken into account at a defined point in time for two different objects with different weighting of at least a part of the piece of detection information for determining the particle contamination information of these two objects.Furthermore, it can be provided, for example, that at least one item of influencing information is taken into account for determining the particle contamination information, wherein the item of influencing information relates to a quantity of particles and / or a type of particles and / or a temperature and / or air humidity and / or flow speed and / or flow direction of an object and / or medium entering the interior of the building and / or exiting the interior of the building. Thus, for example, an air flow passing through an open plant gate into the interior of the building and its loading with articles and / or moisture (air humidity) can be taken into account in order to interpret or map the flow conditions and / or thermodynamic processes within the gas-particle mixture located in the interior of the building in a realistic manner in the light of the detection information detected by the detection devices. These thermodynamic processes determined in this way can in turn be used for determining or estimating particle contamination information at intermediate locations.In this case, the influencing information can preferably represent a degree of loading of particles of the object and / or of the medium during entry into the interior of the building and / or during exit from the interior of the building. Alternatively or additionally, the influencing information can relate to the temperature, the thermal energy, the flow direction and / or flow speed and / or the humidity of a defined volume unit of the object and / or medium entering the interior of the building and / or exiting the interior of the building.The influencing information can comprise, for example, at least one sensor value detected via a sensor device; preferably, the object and / or the medium are detected outside and / or inside the interior of the building for detecting and generating the influencing information. Because the medium and / or object entering and / or exiting the interior is detected by a sensor device, the sensor values determined via the sensor device can be used to generate influencing information which takes into account the influence of the object or gas stream entering and / or exiting the interior of the building on the conditions with respect to the particle contamination prevailing in the interior of the building.Optionally, a sensor system can be used to depict whether, for example, a door of the building is in a (fully) open, a partially open or in a closed state or was present in the case of a view of values that are earlier in time. If the building comprises a plurality of closable openings (e.g. doors, windows and / or gates) or a plurality of accesses to the interior of the building or to at least one sub-region of the building, it is possible that, depending on whether one or more openings of the building are simultaneously at least partially opened, train air information, i.e. an increased flow volume of the room air, is taken into account.The first and / or the at least one further detection device can be connected to one another and / or to the computing unit via a wired and / or a wireless data connection; preferably, a data exchange takes place between at least two detection devices and / or between at least one detection device and the computing unit via an, in particular serial, communication system. The communication system can have, for example, a "local interconnect network" (LIN) and / or a "single-drop digital communication interface for small sensors and actuators" (SDCI), such as an IO link, and / or an RS232 system (also called EIA-485) and / or a process field network (Profinet) and / or a transmission control protocol / Internet protocol (TCP / IP). A first level or a sensor system level can be addressed, for example, via a CAN bus. The data connection of at least two detection devices and / or of at least one detection device and the computing unit can be effected, for example, by means of cloud.The at least one detection device, in particular all detection devices, can, for example, by means of a processing unit on the detection device side (a) execute at least one partial analysis and / or a modification of the detection information before the latter is passed on to a computing unit and / or (b) execute an error analysis for the operating mode of the detection device and / or of erroneous detected measurement values of the detection device. Preferably, in particular in the event of a fault, fault analysis information relating to the fault analysis is passed on to the computing unit. For this purpose, it may be expedient if the at least one detection device, in particular all detection devices, is or are equipped with a powerful processor and / or microcontroller. A powerful processor can be understood here to mean, for example, an ARM / X86 processor of 32 bits and / or a clock frequency of 1GHz-3GHz. The processor and / or microcontroller on the detection device side is preferably designed such that online or real-time analysis of the measured values detected or generated by the detection device can be carried out in order to form the detection information.The detection information can be output, for example, as locally resolved particle contamination information superimposed on an image of at least one section of the building, in particular on a display device as visualized information. The visualized information can preferably be output, for example, as an image sequence, in particular as a three-dimensional image sequence, for displaying the temporal course of the particle contamination. The mapping can relate to a section of the building, i.e. for example a subspace of a larger room of the building and / or at least one individual room from a plurality of rooms of the building. Finally, the illustration can also represent the entire building and the superposition can output a particle contamination related to the entire building. The illustration can show, for example, a schematic image of at least one building part or a real image of at least one building part. In the case of a real image, this can be captured, for example, via a camera device, in particular arranged in at least one capture device. Consequently, it is possible that, in the manner of augmented reality (augmented reality), an image of at least one part of a building and / or of a location in the interior of the building and / or of a variable location and / or of an object (which temporarily moved or moves within the building) can be overlaid with at least one item of particle contamination information.Finally, the mapping may comprise a three-dimensional visualization of the particle contamination information, in particular in a virtual space. For example, the particle contamination can be displayed for a user of smart glasses in a location- and / or time-specific manner when viewing the interior of the building or of the part of the building and / or of an object. The mapping can be output, for example, at a mobile terminal; this can be designed, for example, as an electronic mobile device. For example, a smartphone, a tablet computer and / or a portable computer (e.g. laptop) can be used as the electronic terminal.The computing unit can output countermeasure information, for example, depending on the particle contamination information, in particular, via an output unit (e.g., a display, a mobile electronic device) to a user. Alternatively or additionally, for example, a control signal to one (a) the particle contamination in the interior of the building and / or (b) the particle contamination of a medium and / or object entering the interior of the building and / or (c) the particle contamination of a medium and / or object exiting the interior of the building and / or (d) the air humidity and / or the flow speed and / or the flow direction and / or the temperature of the interior of the building and / or (e) the air humidity and / or the flow speed and / or the flow direction and / or the temperature of a medium and / or object entering the interior of the building and / or (f) the air humidity and / or the flow speed and / or the flow direction and / or the temperature of a medium and / or object entering the interior of the building The control signal can be used to output the influencing device or to actuate this device. In other words, depending on the particle contamination information generated on the basis of the detection information of the detection device, in the course of a target actual calibration relating to at least one criterion (e.g. temperature, particle type, particle quantity, flow speed, flow direction,... ), an action recommendation can be output if a predefined threshold value is exceeded and / or undershot, or a device can be actuated via a control signal. The influencing device can be, for example, a cleaning device for at least areas of the interior of the building and / or for an object moved at least temporarily in the interior of the building. These devices can perform cleaning and / or one of the above-mentioned influences manually or automatically. For example, the device may comprise an air conditioning device for the interior of the building.In one example of application, a device can be controlled as a countermeasure or as a control signal, which device carries out an increase in the air humidity when a predefined particle concentration threshold value is exceeded. For example, by increasing the air humidity, if it has not yet reached a predefined humidity value, the particles located in the room air can agglomerate and settle, so that the relative particle concentration in the room air can be reduced at least in sections, so that, for example, a painting process can be carried out without or with less negative influence by particles located in the room air.A countermeasure which is output after predefined threshold values have been exceeded and / or undershot can comprise, for example, an action recommendation or action instruction which recommends or requests, for example, for carrying out a manual and / or at least partially computer-assisted and / or robot-assisted cleaning process. In the example case of a painting facility, this can comprise, for example, a pre-cleaning of an object to be painted (for example of a vehicle) and / or a cleaning of a tool of the painting facility.In addition to the method for detecting particle contamination inside a building by means of a detection device, the invention relates to an arrangement comprising a first and at least one further detection device which can be or can be arranged in a building, and a computing unit for carrying out the method described herein. This arrangement can be understood as a set or as a plurality of associated objects which can be installed in a building, in particular in an industrial hall. At least one, in particular all, detection devices can be installed, for example, in the building and the computing unit can be placed, for example, at a location located outside the building.All advantages, details, embodiments and / or features of the method according to the invention can be transferred to or applied to the arrangement according to the invention.The invention is explained in more detail on the basis of exemplary embodiments in the drawings. The following shows: FIG. 1 shows a schematic illustration of a plan view into the interior of a building equipped with a plurality of detection devices according to an exemplary embodiment; FIG. 2 shows a schematic illustration of a detection device according to an exemplary embodiment; FIG. 3 is a schematic diagram showing particle contamination information; FIG. 4 shows a schematic schematic schematic diagram of method sequences according to an exemplary embodiment.FIG. 4 schematically shows process sequences of a method for detecting particle contamination in the interior 2 of a building 1 by means of at least one detection device 3, 4. a first detection device 3 is arranged at a first location 5 in the interior 2 of the building 1, wherein a first detection information 101 describing particle contamination in the building 1 is generated via the first detection device 3, and a further detection device 4 is arranged at at least one further location 6 in the interior 2 of the building 1, wherein a further detection information 102 describing particle contamination in the building 1 is generated via the further detection device 4, cf. FIG. 1. the detection information 101, 102 is transmitted to a central processing unit 7 in order to derive particle contamination information 103 from the combined detection information 101, 102. The computing unit 7 can be arranged at least partially in a detection device 3, 4 or-as shown in FIG. 1-can be arranged as a unit separated from the detection device 3, 4, in particular as a unit placed outside the building 1 and separated from the detection device 3, 4.The building 1 can serve, for example, as a painting and / or assembly shop for painting and / or mounting components and / or assemblies. In this case, the building 1 has at least one at least temporarily closable opening 8, 8'. By means of the at least one closable opening 8, 8' it is possible, for example, for an object 9 to be painted (for example components to be mounted) to be introduced into the interior 2 of the building 1 or to be led out of the interior 2 of the building 1.The first and / or the at least one further detection device 3, 4 can, for example, detect the temperature and / or the air humidity and / or flow speed and / or flow direction and / or particle quantity and / or particle type of a gas or gas mixture flowing the interior 2 of the building 1, in particular of a gas or gas mixture containing a number of particles to be detected, and generate detection information 104, 105, 106, 107, 108, 109 comprising temperature and / or air humidity and / or flow speed and / or flow direction and / or particle quantity and / or particle type information.Preferably, the temperature and / or air humidity and / or flow speed and / or flow direction and / or particle quantity and / or particle type information 104, 105, 106, 107, 108, 109 is taken into account for generating the particle contamination information 103.A first piece of detection information 101 of the first detection device 3 can describe, for example, a piece of measured value information 110 of a particle quantity and / or particle type at the first location and a further piece of detection information 102 of the further detection device 4 can describe a piece of measured value information of a particle quantity and / or a particle type at the further location 6. The particle quantity can in particular comprise information about the particle type, preferably about the particle quantities of individual particle types within a volume unit of the room air in the interior 2 of the building 1 and / or on or on a surface of an object 9.A first piece of detection information 101 of the first detection device 3 can describe, for example, a piece of measurement value information 110 of the temperature and / or of the air humidity and / or of the flow speed and / or flow direction at the first location 5, and a further piece of detection information 102 of the further detection device 4 can describe a piece of measurement value information of the temperature and / or of the air humidity and / or of the flow speed and / or flow direction at the further location 6. The particle contamination information 103 preferably comprises an assignment of the determined measured value information to the locations 5, 6 of the acquisition of these measured values. In other words, the particulate contamination information 103 includes location information.For example, the acquisition information 101, 102, in particular the acquired measured value information 110, can be assigned to a time information 111 describing the time of acquisition of the acquisition information 101, 102, in particular the measured value information 110. The particle contamination information 103 preferably comprises an assignment of the detection information 101, 102, in particular a temperature and / or air humidity and / or flow speed and / or flow direction and / or particle quantity information 104, 105, 106, 107, 108, 109, with the time information 111.The time information 111 can be generated in the detection device 3, 4 and / or in the computing unit 7 or assigned to the detection information 101, 102 and / or at least one concrete measured value or at least one concrete measured value information 110. In this case, a storage unit (not shown) can be arranged or designed, for example, in or on the detection device 3, 4 and / or in or on the arithmetic unit 7 in order to store the information assignment.By means of the arithmetic unit 7, for example, an at least partial, in particular complete, evaluation of detection information 101, 102 of at least two detection devices 3, 4 can be carried out, cf. FIG. 4.The particle contamination information 103 describes information about at least the quantity of particles at at least one fixed reference location (e.g. location 5, 6) in the interior 2 of the building 1 and / or about at least one quantity of particles at at least one variable reference location (e.g. on the object 9) in the interior 2 of the building 1.A defined volume can be considered as a variable reference location, for example, which moves on a predefined movement path and at a predefined speed at least in sections through the interior 2 of the building. For example, a component or a vehicle is considered an object which covers a route 18 lying within the interior 2 of the building 1. According to one example, the route 18 can lead from a first opening 8 in the interior 2 of the building 1 to a further opening 8'. In this case, the particle contamination information item 103 with respect to this variable reference location can specify the change in the particle contamination on or on the object 9 or enable the determination thereof. In other words, it is possible to determine which particle type and / or which particle quantity is deposited or released on or on the object 9 from its movement along the route from a first opening 8 to a further opening 8'.The variable reference location or object 9 is assigned to a reference object located at defined locations in the interior 2 of the building 1 at defined times, wherein the particle contamination information 103 of the reference object is generated by taking account of detection information 101, 102, in particular measurement value information 110, of defined locations 5, 6 at defined times. The object 7 or the reference object can be located, for example, at a specific point in time at an intermediate region 10 which lies between two locations 5, 6 each provided with a detection device 3, 4.
