Description

System of linear radio determination on stand alone}

The present invention relates to a stand-alone linear wireless positioning system. More specifically, the present invention relates to a stand-alone linear wireless positioning system, and more specifically, to a relatively simple two-dimensional positioning system that is provided independently and does not use three-dimensional position information directly provided and received from networks and satellites, as in existing wireless positioning methods. Using the information, the receiving side performs positioning through its own processing, and even in the event of a communication failure due to a natural disaster, etc., the current location information can be accurately obtained by wireless positioning inside a linear structure such as a tunnel or using surrounding information in an underground parking lot inside a building. This relates to a stand-alone linear radio positioning system that performs wireless positioning.

Meanwhile, the present invention broadcasts and provides linear positioning information while quickly partially removing fine dust and malicious harmful substances generated by the movement (driving, operation) of the vehicle from the area where the vehicle is detected, thereby purifying the surrounding air. It is about an environmentally friendly stand-alone linear wireless positioning system that purifies water.

There have been many studies and proposals on technologies for tracking the location (coordinates) information of moving objects, and the most widely used technologies recently include methods using the Global Positioning System (GPS), mobile communication networks, terrestrial waves, infrared, and RFID. Various positioning technologies using Radio Frequency Identification (Radio Frequency Identification) and ZigBee, as well as detailed operation methods for each, are being actively researched and developed.

In addition, due to the remarkable development of mobile communication-related technology and the rapid spread of smartphones, location-based service (LBS) technology is being actively researched and developed and serviced, and is known to have relatively high precision. .

In all descriptions below, RF signals and wireless signals are described with the same meaning, coordinate information and location information are described with the same meaning, and vehicle driving, operation, and movement are described with the same meaning, but all are described as appropriate to the context. Each will be listed selectively.

Recently, as chips that perform outdoor wireless positioning using GPS information and mobile communication network information are installed in all smartphones, the GPS market and LBS market are also growing rapidly. Meanwhile, outdoor wireless positioning technology using GPS or mobile communication networks has the advantage of providing high-precision location information outdoors, but the accuracy of wireless positioning decreases as wireless signal loss occurs indoors or in shadow areas. There is a problem of rapid decline.

Therefore, in order to improve the accuracy of wireless positioning indoors or in shaded areas, technology that uses the received signal strength (RSS) of WiFi AP (Access Point) signals, which are widely installed indoors, is being actively researched and introduced. there is.

Indoor wireless positioning using RSS includes a parametric method based on a radio wave model and a non-parametric method based on training data. Among these indoor wireless positioning methods, the technique that is receiving the most attention is the non-parametric fingerprinting wireless positioning method.

The indoor fingerprinting radiolocation technique is a method of collecting RSS values from reference points to build a radio map (RM: Radio Map) and using this radio map to estimate the movement of the terminal.

Building a wireless map using fingerprinting is a common technique, and the method of acquiring RSS values through training for each reference point is called Static RM. In the Static RM method, the once measured value is continuously used without being updated.

A conventional technology that partially solves this problem is ‘Indoor positioning method using Bayesian algorithm’ published by Korean Patent Application No. 10-2010-0036049 (April 19, 2010).

1 is a block diagram illustrating an indoor wireless positioning method according to an embodiment of the prior art.

Hereinafter, as explained with reference to the attached drawings, the received signal strength (RSS) data collected from the reference point (RP) located for wireless LAN is databased (DB) using the fingerprint method and Bayesian learning is performed. This is a radiolocation method using the NBC (Naive Bayesian Classifier) using the posterior probability distribution and the similarity matrix of fuzzy clustering.

This prior art has the advantage of being able to measure location while communicating over the Internet.

However, the conventional technology has the problem of not being able to perform linear positioning in shaded areas such as tunnels where Internet network communication is not possible, so there is a need to develop technology that can perform linear positioning in spaces such as tunnels.

In particular, it does not rely on existing facilities, devices, systems, fingerprints, etc., such as the Internet, mobile communication networks, GPS, etc., but uses simple positioning information and surrounding information provided in linear 2D to determine the location inside linear structures such as tunnels or inside buildings. There is a need to develop technology to accurately wirelessly determine current location information in parking lots, etc.

And for ease of understanding, drawings and descriptions may be omitted.

In the following description, the terms hazardous substances, hazardous compounds, and malignant organic pollutants have the same meaning and will be used selectively as appropriate to the context.

This is also an explanation of the concept.

Hereinafter, the stand-alone linear wireless positioning system 900 according to the present invention will be described in detail with reference to all the attached drawings.

The present invention is not a positioning technology based on GPS signals, network signals of mobile communication systems, Internet signals, etc., due to very poor radio wave environments such as tunnels and underground parking lots, but is a mobile communication portable terminal (smart phone) or corresponding data terminal device. It is a standalone method that performs positioning on its own. In other words, the technical idea is to enable self-positioning from a terminal containing a smartphone or a linear positioning vehicle (5000) without any connection to GPS, location-based service (LBS), or any Internet, etc., and is capable of self-positioning in tunnels and underground parking lots. It is a linear positioning technology that reduces positioning in radio wave shadow areas to one dimension or linear two dimensions.

Two-dimensional surveying or bilateration method is easy for positioning in structures with linear structures such as tunnels, underground or building parking lots, and the same three-dimensional surveying or trilateration method as the existing method. Don't use technology. However, if necessary, by extending the bilaterian measurement technology to n sides, positioning can be done in two-dimensional space and three-dimensional space.

Meanwhile, in WiFi, there is a device name area called SSID and in beacon, called BLE, and a unique name can be given to each device in its own form. Specific location information is recorded in this SSID or device name area, installed linearly, and used for positioning. One of the technical ideas of the present invention is to perform wireless positioning by detecting the recorded (described) coordinate (position) information and received signal strength (RSS). As an example, when a beacon is installed 30m up the Deokjin Tunnel, 'deokjin_up_30' is recorded in the BLE area of the beacon. This information can also be written in the SSID of the Wi-Fi APi, and the user's specific data terminal or specific app This installed smartphone detects the signal of the beacon (or WiFi) and confirms that the current coordinates (location) information is near the point 30 to 40 meters up the Deokjin Tunnel. Therefore, it can be used for independent and two-dimensional wireless positioning even when there is no connection to three-dimensional systems such as the Internet, mobile communications, GPS, etc.

In order to electrolyze water, activation energy corresponding to the overvoltage required to generate a spark of shock discharge is required.

Overvoltage is a phenomenon in which a higher voltage (generally +5% or more) than the highest voltage value that appears between two lines during normal operation is supplied for a long time (generally more than 1 second), and it is difficult to determine what reaction actually occurs at the electrodes. It is defined as an excess potential voltage that exceeds the peak value of the voltage difference that occurs while the same reaction as the voltage occurring is reversibly maintained at the same electrode.

When driving a vehicle, malignant harmful substances including NOX (nitrogen oxides), SOX (sulfur oxides), and Vox (VOX or VOCs, volatile organic compounds) are emitted through the exhaust gases, along with a large amount of fine dust. occurs.

NOX (nitrogen oxides) is a substance produced when part of the nitrogen in the atmosphere reacts with oxygen when fuels such as gasoline and oil are burned at high temperatures. It includes nitrogen monoxide (NO) and nitrogen dioxide (NO2).

SOX (sulfur oxides) is a colorless, irritating, non-flammable gas that is easily soluble in water. It is artificially emitted when fossil fuels such as coal and oil containing sulfur (S) are burned, and is produced in power plants, heating devices, metal smelting plants, etc. It occurs in oil refineries and other industrial processes.

Fine dust (fine dust, particle dust matter) is less than 10 micrometers (um) in diameter, which is about 1/10 the size of a hair with a diameter of 50 to 70 micrometers (um), and is breathed or penetrated into cells. Children, the elderly, and even healthy people may face serious diseases as their immunity declines. Generally, when fine dust penetrates the eyes, it affects allergic conjunctivitis and keratitis, in the nose it affects allergic rhinitis, in the bronchi it affects bronchitis, emphysema and asthma, and in the lungs it is absorbed into the alveoli and destroys lung cells. Damage makes oxygen exchange difficult and reduces the body's immune function, making various diseases worse. It is known to infiltrate cells and circulate through blood vessels, causing cardiovascular diseases including vascular damage, angina, and stroke. In addition, it is known that fine dust that penetrates the human body is not discharged well and accumulates, causing various fatal diseases and diseases.

When electrolyzing water, in addition to the generation of O2 at the anode, active oxygen such as OH group (HO*, hydroxyl radical), hydrogen peroxide (H2O2, hydrogen peroxide), and ozone (O3, ozone) are generated, the technical details of which are well known. .

The technology for generating hydroxyl radicals by applying high voltage discharge to water molecules is disclosed in Korean Patent Registration No. 10-1061227 (2011. 08. 25.) ‘Hydroxy radical water and hydrogen oxygen gas generator using underwater plasma discharge and device using the same. It is described in detail in ‘System’. Hereinafter, water in which ozone and hydroxyl radicals are dissolved will be described as ozone water. This ozone water reacts with water-soluble pollutants to produce NOX (nitrogen oxides), SOX (sulfur oxides), and VOX (VOX or VOCs), volatile pollutants. It is known to remove malignant organic pollutants (hazardous substances) including organic compounds, and is widely used for that purpose.

For the passage of vehicles, there are median dividers and lanes that separate up and down lanes. Meanwhile, it will be explained that tunnels include closed living spaces, such as underground parking spaces in buildings.

If a more precise result value is required, the secondary cubic spline algorithm is applied once again to the result value where the primary cubic spline algorithm was applied, and the result value is recorded in the allocated area and output to the corresponding display while processing the application.

According to one embodiment, if described in detail with reference to the attached FIG. 8, the linear positioning vehicle 5000 drives (moves) next to the linear RF transmitter 2000 arranged in a straight line, and receives each corresponding device name. As a result of detecting and measuring the signal strength (RSS), the device name of the strongest (1st strong) linear RF transmitter (2000) is Deokjin Sanghaeng 40 m (meter), and the device name of the second strongest (2nd strong) wireless transmitter (2000) is If the device name is 30 m up Deokjin, the location (coordinates) information corresponding to the range of 35 to 40 m up Deokjin Tunnel is analyzed and displayed as the coordinates (position) information of the current driving.

In other words, the location information is recorded in each device name area of one or more beacons or Wi-Fi APs constituting the linear RF transmitter 2000, and is output wirelessly in the corresponding manner, and is placed in a straight line in the tunnel area or shaded area. Because of the placement and installation, RF (radio frequency) signals can be transmitted using a linear RF transmitter (2000) consisting of a beacon or Wi-Fi AP even in tunnel areas and shadow areas such as building parking lots where GPS signals or LBS signals cannot be received wirelessly. It has the advantage of enabling linear positioning.

Here, the straight lines are arranged in a row and will be explained and understood as including a curved shape suitable for vehicle driving due to the shape of the tunnel. Meanwhile, in the case of FM broadcasting, it will be explained and understood that the location information is broadcast in a timeslot method and the receiving side is also equipped with a configuration to receive and extract the information.

Meanwhile, as shown in FIG. 11, when the linear RF transmitters 2000 arranged in a row in a tunnel or shaded area are overlapped and placed in a row again at regular intervals, coordinate (position) information is detected three-dimensionally even in the tunnel or shaded area. Or you can check.

In other words, as an example, when the beacon constituting the linear RF transmitter 2000 is installed at a random location When a beacon is installed and the RSSI value of the beacon is the maximum at that location, it means that the beacon is closest compared to other beacons. In order for this interpretation to be established, beacons with the same specifications (standards) must be set to the same state. It is very important to record the location information in each device name area and install them at even intervals, and it is explained that all of these conditions are satisfied.

Confirm the second moving speed of the adjacent linear positioning vehicle (5000) by analyzing, and calculate the arithmetic mean value of the first moving speed and the second moving speed to check the moving speed of the adjacent linear positioning vehicle (5000) more precisely. The corresponding message is output and displayed on the message display unit 3400. In other words, it can determine whether the driving speed is slower or faster than the permitted driving speed, and performs the necessary control while controlling and monitoring to output the necessary messages such as low speed, constant speed, and excessive speed.

The linear positioning vehicle (5000) moves (travels) inside the tunnel (1000), receives and analyzes wireless signals from each linear RF transmitter (2000), and performs linear positioning, and sends the traveling wind to the eco-friendly linear power generation unit (4000).

The linear positioning vehicle (5000) uses received signal strength (RSSI) technology to select the closest linear RF transmitter (2000) among a plurality of linear RF transmitters (2000) lined up in a row and transmits the corresponding information. It is received and analyzed, so linear positioning is carried out.

The technique of calculating the distance between the linear RF transmitter (2000) or beacon (or Wi-Fi AP) and itself or the linear positioning vehicle (5000) using received signal strength (RSSI) technology requires setting various variables. This includes variables such as the transmission power of the beacon itself and RSSI at the reference point depending on the antenna design. In addition, since the RSSI value itself is greatly affected by the environment such as walls and obstacles, it is assumed that one setting is applied to all users in environments such as tunnels where users cannot be limited to pedestrians or in environments where there are many moving obstacles. Although there is some difficulty in converting the RSSI value itself into a distance and obtaining location (coordinates) information, it is the best method in areas with poor radio wave environments.

In addition, the Spline algorithm is used for linear positioning, and since the spline or cubic spline algorithms are generally well known, detailed explanations will be omitted.

Meanwhile, when building a linear positioning system, multiple beacons (WiFi APs) with the same specifications and settings are arranged in a row at regular intervals and in order, the location information and RSSI value of each beacon (WiFi AP) are detected, and the spline algorithm is applied. It is explained that location information can be determined through .
