Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a notification system, particularly to a system for notifying environmental pollution status.

Description of the Related Art

With the advancement of industry and commerce, modern people spend more and more time indoors. Most of the buildings in recent years have closed designs. Often due to poor ventilation in the indoor environment, air pollutants are easy to accumulate in the indoor environment, which affects human health. Compared with the outdoor environment, the concentration of indoor air pollutants is often higher than that of outdoor air pollutants. Therefore, the importance and safety of indoor air quality are more concerned and valued by people.

Generally, there are many sources of pollutants that cause indoor air pollution, such as cooking, smoking, spraying, or human activities of using indoor building materials, plywood, and resin adhesives, which may produce hazardous pollutants such as volatile organic compounds and suspended particles. Therefore, in addition to increasing the ventilation rate of the indoor environment, air purifiers can also be used to effectively remove indoor air pollutants in order to improve indoor air quality. However, air purifiers can only remove parts of the pollutants in the indoor space. No one knows which part of the indoor space has more pollutants and which part of the indoor space has fewer pollutants.

To overcome the abovementioned problems, the present invention provides a system for notifying environmental pollution status, so as to solve the afore-mentioned problems of the prior art.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to embodiments illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts. In the drawings, the shape and thickness may be exaggerated for clarity and convenience. This description will be directed in particular to elements forming part of, or cooperating more directly with, methods and apparatus in accordance with the present disclosure. It is to be understood that elements not specifically shown or described may take various forms well known to those skilled in the art. Many alternatives and modifications will be apparent to those skilled in the art, once informed by the present disclosure.

When an element is referred to as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment.

The invention is particularly described with the following examples which are only for instance. Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the following disclosure should be construed as limited only by the metes and bounds of the appended claims. In the whole patent application and the claims, except for clearly described content, the meaning of the articles “a” and “the” includes the meaning of “one or at least one” of the elements or components. Moreover, in the whole patent application and the claims, except that the plurality can be excluded obviously according to the context, the singular articles also contain the description for the plurality of elements or components. In the entire specification and claims, unless the contents clearly specify the meaning of some terms, the meaning of the article “wherein” includes the meaning of the articles “wherein” and “whereon”. The meanings of every term used in the present claims and specification refer to a usual meaning known to one skilled in the art unless the meaning is additionally annotated. Some terms used to describe the invention will be discussed to guide practitioners about the invention. The examples in the present specification do not limit the claimed scope of the invention.

Furthermore, it can be understood that the terms “comprising,” “including,” “having,” “containing,” and “involving” are open-ended terms, which refer to “may include but is not limited to so.” In addition, each of the embodiments or claims of the present invention is not necessary to achieve all the effects and advantages possibly to be generated, and the abstract and title of the present invention is used to assist for patent search and is not used to further limit the claimed scope of the present invention.

Further, in the present specification and claims, the term “comprising” is open type and should not be viewed as the term “consisted of.” In addition, the term “electrically coupled” can be referring to either directly connecting or indirectly connecting between elements. Thus, if it is described in the below contents of the present invention that a first device is electrically coupled to a second device, the first device can be directly connected to the second device, or indirectly connected to the second device through other devices or means. Moreover, when the transmissions or generations of electrical signals are mentioned, one skilled in the art should understand some degradations or undesirable transformations could be generated during the operations. If it is not specified in the specification, an electrical signal at the transmitting end should be viewed as substantially the same signal as that at the receiving end. For example, when the end A of an electrical circuit provides an electrical signal S to the end B of the electrical circuit, the voltage of the electrical signal S may drop due to passing through the source and drain of a transistor or due to some parasitic capacitance. However, the transistor is not deliberately used to generate the effect of degrading the signal to achieve some result, that is, the signal S at the end A should be viewed as substantially the same as that at the end B.

Unless otherwise specified, some conditional sentences or words, such as “can”, “could”, “might”, or “may”, usually attempt to express what the embodiment in the present invention has, but it can also be interpreted as a feature, element, or step that may not be needed. In other embodiments, these features, elements, or steps may not be required.

In the following description, a system for notifying environmental pollution status will be provided, which uses wireless environment sensing devices to implement environmental detection distribution in three-dimensional space, thereby providing a recommended path.

FIG. 1 is a schematic diagram illustrating a system for notifying environmental pollution status according to an embodiment of the present invention. Referring to FIG. 1, a system 1 for notifying environmental pollution status is introduced as follows. The system 1 for notifying environmental pollution status includes a plurality of wireless environment sensing devices 10 and a portable wireless environmental pollution status notification device 11. The portable wireless environmental pollution status notification device 11 may be installed on a user and follows the user's movements. The wireless environment sensing devices 10 are respectively arranged in the different sensing locations S of a physical environment 2. The portable wireless environmental pollution status notification device 11 is wirelessly connected to the wireless environment sensing devices 10 and located in the physical environment 2. For example, the wireless environment sensing devices 10 are wirelessly connected to the portable wireless environmental pollution status notification device 11 using WiFi direct technology and Bluetooth® technology. The wireless environment sensing devices 10 respectively store the sensing locations S and respectively sense pollution related information P corresponding to the different sensing locations S to output the pollution related information P and the sensing locations S corresponding thereto. The portable wireless environmental pollution status notification device 11 receives the pollution related information P and the sensing locations S corresponding thereto and generates notification signals N based on the pollution related information P and the sensing locations S corresponding thereto. The notification signals N may include an image signal, a sound signal, and a vibration signal. The sensing location S can be expressed in a rectangular coordinate system or a spherical coordinate system.

FIG. 2 is a schematic diagram illustrating a wireless environment sensing device according to an embodiment of the present invention. Referring to FIG. 2, each of the wireless environment sensing devices 10 includes at least one first pollutant sensor 100, a first image sensor 101, a first thermal imaging camera 102, a storage device 103, a first wireless communication module 104, and a first processor 105. For convenience and clarity, the number of the first pollutant sensor 100 is one. The first wireless communication module 104 is wirelessly connected to the portable wireless environmental pollution status notification device 11 using WiFi direct technology and Bluetooth® technology. The first processor 105 is electrically connected to the first pollutant sensor 100, the first image sensor 101, the first thermal imaging camera 102, the storage device 103, and the first wireless communication module 104. The first pollutant sensor 100 measures the first pollution parameter PO1 of first pollutants corresponding to the sensing location S. For example, the first pollutants may include, but are not limited to, bacteria, mold, viruses, flame, smoke, liquefied gas, carbon monoxide, carbon dioxide, ozone, alkane gases, benzene gases, ketone gases, natural gas, coal gas, gasoline, chlorine, ammonia, flammable gases, harmful volatile matter, or airborne matter. The first pollutant sensor 100 may be, but not limited to, an optical finger navigation (OFN) sensor, a wind speed sensor, a chemical sensor, or an optical sensor. When the pollutant is carbon monoxide, the carbon monoxide will absorb the infrared rays with a wavelength of about 4700 nanometers generated by the OFN sensor. The carbon monoxide will reflect the infrared rays back to the OFN sensor. The difference between the intensities of the reflected and generated infrared rays is used to calculate the concentration of carbon monoxide. The first pollution parameter PO1 may be, but not limited to, a pollution concentration, a wind speed, a pollution range, or a flame burning intensity. The first image sensor 101 and the first thermal imaging camera 102 respectively capture a first visible light image V1 and a first thermal image T1 within the same range. The storage device 103 stores the sensing location S. The first processor 105 extracts the first temperature range of the first thermal image T1, uses the first pollution parameter PO1 as the pollution related information, and transmits the sensing location S and the first pollution parameter PO1 to the portable wireless environmental pollution status notification device 11 through the first wireless communication module 104.

When the first pollution parameter PO1 is greater than a given value, the first processor 105 notifies the portable wireless environmental pollution status notification device 11 through the first wireless communication module 104 that the sensing location S corresponding to the first pollution parameter PO1 greater than the given value is a polluted location. When the first visible light image V1 has a human face image and the first temperature range is greater than a given temperature for a given time period, the first processor 105 notifies the portable wireless environmental pollution status notification device 11 through the first wireless communication module 104 that the sensing location S corresponding to the first temperature range greater than the given temperature is a polluted location. When the first visible light image V1 has a human face image and the first temperature range is greater than a given temperature for a given time period, the first processor 105 transmits the human face image to the portable wireless environmental pollution status notification device 11 through the first wireless communication module 104. When the first visible light image V1 has a human face image and the first pollution parameter PO1 is greater than a given value for a given time period, the first processor 105 transmits the human face image to the portable wireless environmental pollution status notification device 11 through the first wireless communication module 104.

FIG. 3 is a schematic diagram illustrating a first pollutant sensor according to an embodiment of the present invention. Please refer to FIG. 2 and FIG. 3. When the first pollutant is a bioaerosol containing bacteria, mold, or viruses, the first pollutant sensor 100 may include a particle cutter 1000, a particle counter 1001, a particle buffer chamber 1002, an air pump 1003, a fluorescence detector 1004, and a microcomputer control unit 1005. The particle cutter 1000, the particle counter 1001, the particle buffer chamber 1002, and the air pump 1003 are connected in sequence through gas pipelines. The particle buffer chamber 1002 is connected to the fluorescence detector 1004 through a gas pipeline. The microcomputer control unit 1005 is electrically connected to the first processor 105, the particle counter 1001, and the air pump 1003. When the air pump 1003 starts to operate, the air pump 1003 absorbs a bioaerosol G and transmits it to the particle cutter 1000. The particle cutter 1000 can filter out particles, water droplets, oil droplets and smoke particles with a particle diameter greater than 10 microns (μm) in the sampled bioaerosol G to avoid interference caused by non-biological aerosols that can produce fluorescence, thereby reducing the error rate of the device. The particle counter 1001 may operate based on the light scattering principle. The particle counter 1001 is placed before the particle buffer chamber 1002 and after the particle cutter 1000 to determine the optical equivalent particle diameter and the concentration of the particles of the bioaerosol G to be measured. The fluorescence detector 1002 is used to detect the fluorescence intensity of the particle clusters of the bioaerosol G in the particle buffer chamber 1002. Specifically, the fluorescence detector 1002 includes an excitation light source and a photodetector. The photodetector is used to obtain the fluorescence intensity of the particle cluster of the bioaerosol G excited by the excitation light in the particle buffer chamber 1002, convert the fluorescence intensity into an electrical signal, and transmit the electrical signal to the microcomputer control unit 1005. The microcomputer control unit 1005 divides the fluorescence intensity by the atmospheric volume to obtain the concentration of the bioaerosol G and uses the concentration of the bioaerosol G as the concentration of pollutants. The first pollutant sensor 100 can also refer to Chinese patent with application number CN201310009382.X.

FIG. 4 is a schematic diagram illustrating a portable wireless environmental pollution status notification device according to an embodiment of the present invention. Referring to FIG. 4 and FIG. 2, the portable wireless environmental pollution status notification device 11 may include a second wireless communication module 110, a second processor 111, a portable display 112, at least one portable sound player 113, and a portable vibrator 114. For convenience and clarity, the number of the portable sound player 113 is one. The second processor 111 is electrically connected to the second wireless communication module 110, the portable display 112, the portable sound player 113, and the portable vibrator 114. The second wireless communication module 110 is wirelessly connected to the first wireless communication module 104 using WiFi direct technology and Bluetooth® technology. The second processor 111 receives the sensing location S and the first pollution parameter PO1 through the second wireless communication module 110. The second processor 111 drives the portable display 112 to generate the image signal D based on a given condition, the sensing location S, and the first pollution parameter PO1. The second processor 111 may drive the portable display 112 to display the detected human face image or the detected polluted location and notify the user that the human face image or the polluted location is a potential source of pollution. The second processor 111 may drive the portable sound player 113 to generate the sound signal U based on the sensing location S and the first pollution parameter PO1. For example, different first pollution parameters PO1 respectively correspond to different sound signals U. If there are a plurality of portable sound players 113, the portable sound players 113 are respectively arranged on different sides of the user. The second processor 111 drives the portable vibrator 114 to generate the vibration signal B based on the sensing location S and the first pollution parameter PO1. For example, different first pollution parameters PO1 respectively correspond to different vibration frequencies or different vibration intensities of the vibration signals B.

The given condition includes one of the different sensing locations S as an ending location. The second processor 111 receives reference signal received power (RSRP), signal-to-interference-plus-noise ratios (SINRs), packet round-trip time (RTT), angles of arrival, and angles of departure from the first wireless communication module 104 through the second wireless communication module 110 and calculates the location of the second processor 111 as a starting location based on at least three of the different sensing locations S and the RSRP, the SINRs, the packet RTT, the angles of arrival, and the angles of departure corresponding thereto. The starting location is known. Thus, when the first pollution parameter PO1 corresponding to the starting location close to the sensing location S is greater, the intensity of the corresponding sound signal U or vibration signal B is greater or the vibration frequency of the corresponding vibration signal B is greater.

The second processor 111 plans candidate paths connected between the ending location and the starting location based on the different sensing locations S, calculates risk values corresponding to the candidate paths, and selects the candidate path corresponding to the highest one or the lowest one of the risk values as a recommended path.

$\mathrm{The}\mathrm{risk}\mathrm{value}={\sum }_{i=1}^n\frac{\mathrm{Pi}}{\mathrm{Di}}.$

Di represents a distance between the starting location and the i-th sensing location corresponding to the candidate path. Pi represents the first pollution parameter PO1 measured in the i-th sensing location S corresponding to the candidate path. n represents the total number of the sensing locations S corresponding to the candidate path. The image signal D shows the recommended path and an image corresponding to the sensing locations S, the first pollutants, and the first pollution parameter PO1. FIG. 5 is a schematic diagram illustrating sensing locations according to an embodiment of the present invention. Refer to FIG. 4 and FIG. 5. Assume that the starting location is the location of area M and that the ending location is the location of area A. There are two candidate paths in total. The first candidate path includes areas I, E, and A and the second candidate path includes areas N, J, F, B, and A. Assume that coefficients Di corresponding to areas I, N, E, J, F, B and A are 1, 1, 2, 1.5, 2.5, 3.5 and 3 respectively. The first pollution parameters PO1 corresponding to areas I, N, E, J, F, B and A are respectively 5, 1, 2, 3, 8, 1 and 6. Therefore, the risk value of the first candidate path=1/1+2/2+6/3=4.

If one intends to avoid pollution sources, the first candidate path is selected as the recommended path. If one intends to clean up the pollution source, the second candidate path is selected as the recommended path.
