Description

Environmental information monitoring system {ENVIRONMENT INFORMATION MONITORING SYSTEM}

The present invention has been made to improve the prior art as described above, the sensor device is installed on a route bus that repeats a certain section movement to sense the environmental data, and the coordinator device installed for each bus stop via the bus is the bus Receiving the environmental data from the sensor device at the time of entry and transmits to the central information server, the environmental information monitoring system that can monitor the environmental information for all the area via the bus with only one sensor.

The environment of the earth is becoming more and more devastated by the increase of population and the concentration of large cities, the products of the 20th century industrialization. Therefore, it is more urgent to prepare attention and measures for the environment these days which is the information age of the 21st century. Global warming, one of the emerging environmental problems, is a phenomenon in which the temperature of the earth rises, which is pointed to by the green house effect caused by greenhouse gases. In other words, global temperatures continue to rise due to the increase in greenhouse gases released into the atmosphere during the burning of human activity, especially fossil fuels.

The greenhouse effect refers to a phenomenon in which the temperature of the atmosphere rises as greenhouse gases absorb some of the reflective heat as the solar heat is projected and reflected on the earth. Earth must release its heat into outer space to maintain a constant temperature. However, the atmospheric temperature rises because greenhouse gases absorb the radiant energy emitted from the earth's surface into the atmosphere and release it back to the surface.

The hypothesis that global warming due to the greenhouse effect will eventually devastate the earth and bring about the end of humanity is no longer acceptable. In addition, global warming has melted icebergs in the Arctic and Antarctic, leading to an increase in sea level throughout the world, and a great threat to ecosystems such as heavy rains, heavy snowfall, and heat waves.

In order to prepare such an environmental countermeasure, it is necessary to always monitor the environmental state of all places in real time and prepare environmental information that prepares statistics on it. For example, a system is installed in which sensors are installed throughout the city for real-time environmental monitoring of a city, and a city server generates environment information of the city based on environmental data obtained from each sensor.

In this case, the important point is that a large amount of sensors need to be installed throughout the city to generate more accurate environmental information. That is, as more sensors are installed, it will be apparent that more environmental data can be acquired to generate more accurate environmental information. However, due to cost and installation space, it is virtually impossible to install the sensor in every building or road.

Accordingly, there is a demand for the development of an environmental information monitoring system capable of obtaining economical and more accurate environmental information by collecting the maximum environmental data with only the minimum sensor.

The present invention has been made to improve the prior art as described above, and provides a sensor device for sensing environmental data on a route bus that operates a certain route repeatedly, and from the sensor device at a bus stop where the route bus stops. By installing a coordinator device for receiving environmental data, the central information server collects environmental data from a plurality of coordinator devices installed at each bus stop and generates environmental information, thereby minimizing the number of installation of sensors and at the same time providing more accurate environmental information. To provide an environmental information monitoring system that enables monitoring

In order to achieve the above object and solve the problems of the prior art, the environmental information monitoring system according to the present invention is installed in a public means of transportation, sensing the environmental data around the public means of transportation at a predetermined period (predetermined) Sensor device; A coordinator device installed at the stop of the public transportation means and receiving the environmental data from the sensor device; And a central information server receiving the environment data from the coordinator device to generate environment information.

According to the environmental information monitoring system of the present invention, a sensor device for sensing environmental data is installed on a route bus that repeatedly runs a certain route, and the environment data is received from the sensor apparatus at a bus stop where the route bus stops. By installing a coordinator device, the central information server collects environmental data from a plurality of coordinator devices installed at each bus stop and generates environmental information, thereby minimizing the number of sensor installations and monitoring more accurate environmental information. You can get the effect.

The public transportation means referred to herein is a concept including a bus, train, taxi, etc. that run a certain line. That is, the sensor device according to the present invention may be installed in a bus that runs a certain route, may be installed in a train, or may be installed in a taxi. However, in the present specification, for the convenience of description, a case where the sensor device is installed on a bus running a certain route will be described as an example.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a view showing the configuration of an environmental information monitoring system according to an embodiment of the present invention.

The environmental information monitoring system according to the exemplary embodiment of the present invention includes a sensor device 131, coordinator devices 111 and 121, and a central information server 140.

The sensor device 131 is installed on the bus 130. The bus 130 may be implemented as a route bus that runs a certain route. For example, the bus 130 may be implemented as a city bus that operates a certain line in a city, a wide area bus that operates a wide area autonomous section, or a high speed bus or an intercity bus that operates a long distance route.

In addition to the bus 130, the sensor device 131 may be installed in various vehicles such as a commercial vehicle, a monorail electric car, a train, an airplane, and the like that operate a certain line. However, in the present specification, for the convenience of description, the case where the sensor device 131 is implemented as a city bus running on a certain line in the city will be described as an example.

The sensor device 131 senses the environmental data around the bus at predetermined periods. The period may be selected by time or by distance. For example, the sensor device 131 may sense surrounding environmental data every three minutes until the bus 130 starts from the bus stop 1110 and arrives at the bus stop 2 120. In addition, the sensor device 131 may sense the environmental data at 50m intervals from the bus 130 to the bus stop 2 120 until the bus 130 arrives at the bus stop 2 120. Selection of the period may be implemented in various ways according to the judgment of those skilled in the art.

The sensor device 131 includes at least one of a temperature sensor, a humidity sensor, an illuminance sensor, an air pollution sensor, and an acceleration sensor. That is, the sensor device 131 uses temperature sensors, humidity data, illuminance data, and air pollution data for each cycle selected by the bus 130 in the bus stop 1 (110) and bus stop 2 (120) sections through the aforementioned sensors. One or more of the environmental data may be sensed. However, the above-described sensor type is merely an example for convenience of description, and the sensor device may be implemented to sense various data including various types of sensors according to the judgment of those skilled in the art.

The sensor device 131 generates sensing time data for the time when the environment data is sensed. For example, when the bus 110 departs the bus stop 1 (110) at 7:10 and senses environmental data at 7:13 by 3 minutes of the sensing cycle, the sensor device (130) detects the 7 o'clock. Sensing time data for 13 minutes is generated and included in the environment data. Therefore, the environmental data may be implemented to include the sensing time data.

The sensor device 131 maintains bus information. The bus information includes the line number of the bus 131. In addition, the bus information may be implemented to include not only the route number but also various information for allowing the central information server 140 to identify the bus 130, such as the vehicle number of the bus 131.

Coordinator devices 111 and 121 are installed at bus stops 110 and 120. Coordinator device 1 (111) is installed in bus station 1 (110), and coordinator device 2 (121) is installed in bus station 2 (120). That is, a coordinator device may be installed at all bus stops of a line on which the bus 130 operates.

The coordinator device 2 121 receives the environmental data from the sensor device 131 when the bus 130 enters or stops at the bus stop 2 120. That is, the one or more environmental data sensed by the sensor device 131 at the bus stop 1 (111) and the bus stop 2 (121) sections is the coordinator device when the bus 130 enters or stops at the bus stop 2 (120). 2 is sent.

In addition, the sensor device 131 transmits the bus information about the bus 130 to the coordinator device 2 121 together with the transmission of the environmental data. The environment data includes the sensing time data as described above. The coordinator device 2 121 may record the environmental data and the bus information simultaneously received from the sensor device 131 in a memory in correspondence with each other. To this end, the coordinator device 2 121 includes USB memory of various capacities, CF memory, SD memory, mini SD memory, XD memory, memory stick, memory stick duo, SMC memory, MMC memory, or RS-MMC. The memory may include a memory including a hard disk used in a general PC or a notebook.

The sensor device 131 transmits the environmental data and the bus information to the coordinator device 2 121 through short-range wireless communication. The short range wireless communication may be implemented by any one of Bluetooth, Zigbee, infrared communication (IrDA), Ultra Wide Band (UWB), or WLAN (IEEE802.11b). In addition, the short range wireless communication may be implemented to include all kinds of short range wireless communication widely used in the art that can transmit and receive the environmental data and the bus information.

The coordinator devices 111 and 121 maintain bus stop information for the bus stops 110 and 120 through the memory. The bus stop information may be embodied as a name of a bus stop or a code given to each bus stop.

The coordinator device 2 121 transmits the environmental data, the bus information, and the bus stop information from the sensor device 131 to the central information server 140 through wired or wireless communication. The wired / wireless communication is a concept including various wired communication networks such as PSTN, PSDN, ISDN, XDSL, optical communication, and ETHERNET and wireless communication networks such as CDMA, WCDMA, WiBro, and HSDPA. To this end, the coordinator devices 111 and 121 include various types of communication modules for performing the above-described various wired and wireless communication.

The coordinator apparatus 2 121 includes display means, such as LED and LCD. The coordinator device 2 121 may display the environmental data received from the sensor device 131 and recorded in the memory on the display means. Therefore, various environmental data of the section of bus stop 1 (110) and bus stop 2 (120) may be displayed on the display means. Accordingly, the passengers waiting for the bus stop 2 121 may acquire environmental information of the bus stop 1 110 and the bus stop 2 120 in real time through the environmental data displayed on the display means.

The central information server 140 receives the environment data, the bus information, and the bus stop information from the coordinator device 2 121. The environmental information of the bus stop 1 (110) and bus stop 2 (120) section is generated using the environment data, the bus information, and the bus stop information. That is, the central information server 140 determines that the environmental data is the environmental data sensed in the bus stop 1 (110) and bus stop 2 (120) sections by using the bus information and the bus stop information. Environment information can be generated.

The central information server 140 may generate one piece of environment information by calculating an average of the one or more pieces of environment data sensed in the section of bus station 1 110 and bus station 2 120, and includes the environment data. The sensing time data may be used to generate environment information corresponding to the time or point at which the respective environment data is sensed.

The central information server 140 transmits the environment information to the coordinator device 2 121 through the wired or wireless communication. The coordinator device 2 121 stores the environment information received from the central information server 140 in the memory and then displays the environmental information on the display means, whereby waiting passengers of the bus stop 2 120 may receive bus stop 1 110. And it can be obtained in real time to the environment information of the bus stop section 2 (120). In addition, the central information server 140, as well as the environmental information for the bus stop 1 (110) and the bus stop 2 (120) section, the environmental information for the entire section of the running route of the bus 130 or the environmental information of the entire city, Environmental information for each region may be transmitted to the coordinator device 2 121 and displayed on the display means. This will be described with reference to FIG. 2.

2 is a diagram illustrating a plurality of buses and a plurality of bus stops in which a sensor device and a coordinator device are installed according to an embodiment of the present invention.

Environmental information monitoring system according to an embodiment of the present invention includes a plurality of buses and a sensor device and a coordinator device respectively installed in a plurality of bus stops each bus operates. For example, as shown in FIG. 2, the sensor device 1 (not shown) includes a shrine 211, Nonhyeon 212, Kyobo Intersection 213, Gangnam Station 214, and Woosung Apartment 215 Bang Bang Intersection. 216, and bus 1 210 that runs between Yangjae Station 217.

In addition, sensor device 2 (not shown) includes Gubanpo 221, high-speed terminal 222, Samho apartment 223, Gangnam station 214, Yeoksam station 224, Renaissance hotel 225, and Seolleung station 226. It may be installed in the bus 2 (220) for operating the section.

In addition, the sensor device 3 (not shown) is Gubanpo 221, high-speed terminal 222, Sinbanpo 231, Nonhyeon 212, Hakdong Station 232, Korea Customs Service crossroad 233, and Gangnam-gu Office 234 It may be installed in the bus 3 (230) that operates.

The coordinator device may be installed at each bus stop as described above. The coordinator device may be installed at all the bus stops, or may be installed one by one at a plurality of bus stops at regular intervals. In addition, the coordinator device may be installed only at the departure stop and the arrival stop of each bus line. This may be implemented in various ways according to the judgment of those skilled in the art. However, in the present specification, for the convenience of description, the case in which the coordinator devices are installed at all the bus stops described above will be described as an example.

A central information server (not shown) receives environmental data, bus information, and bus stop information from each coordinator device. The central information server may determine which section of the environmental data is the received environmental data through the bus information and the bus stop information.

For example, in the case of Gangnam Station 214, Bus 1 210 and Bus 2 220 are both bus stops. Accordingly, the central information server may determine which section the environmental data is about through bus information received from the coordinator device installed in the Gangnam station 214. For example, the central information server may determine that the environmental data received together with the bus information 1 from the coordinator device installed in the Gangnam station 214 is the environmental data of the section of Kyobo Intersection 213 and the Gangnam Station 214. In addition, the central information server may determine that the environmental data received together with the bus information 2 from the coordinator device installed in the Gangnam station 214 is the environmental data of the Samho apartment 223 and the Gangnam station 214.

In this way, the central information server receives environmental data from the coordinator device installed at each bus stop. The central information server may generate respective environmental information corresponding to the respective environmental data and transmit the generated environmental information to the corresponding coordinator device. The central information server may provide comprehensive environmental information of the region illustrated in FIG. It may be generated and transmitted to each coordinator device.

As described above, according to the environmental information monitoring system of the present invention, it is possible to expect the effect of obtaining environmental data of a wider section even with a minimum sensor device. For example, the environmental data for the entire region shown in FIG. 2 may be acquired by only three sensor devices respectively installed on the bus 1 210, the bus 2 220, and the bus 3 230.

That is, according to the environmental information monitoring system of the present invention, in the case of the bus 1 (210) route, if two environmental data sensing cycles are selected for each bus stop, 12 environmental data are collected in the section of the shrine 211 and Yangjae station 217. It can be obtained through one sensor device installed in the bus 1 (210). However, in the conventional environmental information monitoring system, in order to acquire the 12 environmental data, 12 sensors must be installed on the route of bus 1 210 and a coordinator device must be installed at each bus stop, so that it can be operated economically and inefficiently. There is nothing else.

In addition, according to another embodiment of the present invention, when the coordinator device is installed only at the shrine 211, which is the departure stop, and the Yangjae station 217, which is the arrival stop, on the bus 1 210 line, one sensor is appropriately selected. Since only a device and two coordinator devices can obtain a large number of environmental data for the entire route of bus 1 210, the effect of monitoring more accurate environmental information can be expected at a minimum cost.

While specific embodiments of the present invention have been described so far, various modifications are possible without departing from the scope of the present invention.

Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims below, but also by the equivalents of the claims.
