Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to an apparatus for monitoring an environment using a communication network driven based on solar energy. In particular, it is related to environmental monitoring of mountainous areas without electricity or network, and a system for rapid emergency contact in case of power failure is also established.

According to the present invention, the power supply unit 20 controls the solar panel 22 and the battery 26 with the power generation control module 24 to secure driving power. The solar panel 22 is coated with a material that is protected by tempered glass in consideration of being installed in a remote area and difficult to attach foreign matters. The battery 26 uses a rechargeable secondary battery and serves as an auxiliary power source in an emergency. The power generation control module 24 is protected in the control unit 50, which will be described later. When the power generation power supply of the solar panel 22 is stably supplied to the battery 26 and stored therein, Turn on the power. 4 illustrates a circuit diagram of a power generation control module 24 for performing such a function.

In this case, the power unit 20 may be configured of a network including at least partly a telephone pole 12 or a street lamp 14 to receive emergency power, but control the solar panel 22 and the battery 26. Consider using it as a module 24. And the control unit 50 is to be installed in the general telephone pole 12 or the street lamp 14, but in the mountainous region may use the telephone pole 12 or the transmission line, if there is a private house or road in between the street lamp (14) You can also use This is because it can be a means for securing the minimum power in case the function of the solar panel 22 and the battery 26 is lost. Of course, since the present invention is based on low-power short-range wireless network communication, in most cases, power supply is sufficient even with solar power generation.

On the other hand, as shown in Figure 2 may be configured a network according to the present invention by using a strut 16 without a separate power source between the telephone pole 12 or the street lamp (14).

In addition, according to the present invention, the sensor module 30 receives the power of the power unit 20 to convert an environmental condition and a physical quantity of a disaster or not into an electrical signal. The sensor module 30 means an aggregate of individual sensors corresponding to each physical quantity, but is not necessarily limited to being integrated into one substrate.

At this time, the sensor module 30 includes at least one or more of temperature, wind direction, wind speed, precipitation, snow amount as physical quantities of environmental conditions, fire, earthquake, radioactivity, yellow dust, atmospheric gas, water quality measurement, At least one or more of the toxic gas. While temperature can be detected by a temperature sensor, wind speed, wind direction, precipitation, and snow cover may be combined with known instruments (not shown) to increase accuracy. Fire is detected by smoke or camera images, yellow dust is detected by fine dust concentrations, atmospheric gases are detected by concentration detectors, water quality can be analyzed by water quality meters, and toxic gas leaks from gas pipes are detected by the corresponding sensors. . For the detection of more specialized physical quantities, including earthquakes and radioactivity, they may be associated with separate equipment (not shown).

In addition, according to the present invention, the control unit 50 stores the signal of the sensor module 30 and performs transmission and reception through the wireless communication unit 55. One control unit 50 constitutes an independent node together with one power unit 20 and one sensor module 30, and such nodes are in series (straight line type), preferably mesh type (mesh type). ) To form an entire network. Of course, if necessary, a private network of individuals and groups can be used together. When the control unit 50 is arranged in the form of a net, even if part of the power off (off) or damaged due to natural disasters or accidents, it is possible to remotely contact and relay connection. Each control unit 50 includes identification information including the place where it was installed.

The control unit 50 according to the present invention includes a microcomputer 51, an input / output unit 52, a storage unit 53, a wireless communication unit 55, and an antenna 56 as main components. It is based on the 2.4 GHz ISM band, but eliminates the use of other bands, such as 5.0 GHz, to place the control unit 50 at intervals of approximately 300 to 1,000 m (preferably 300 to 500 m) and to implement low power short-range wireless communications. I never do that. The present invention also includes a case in which the storage unit 53 and the display 42 or one of them are excluded, and the antenna may be installed in the control unit 50 so that the shape and shape of the antenna may be formed in the external protrusion type as shown in the drawings. It is not limited. In either case, the use of near field communication as a repeater can be used for telecommunication and sensor networks. Unlike the control unit 50, some of the sensors (eg, seismic sensors) of the sensor module 30 may be arranged at wider intervals.

In this case, the control unit 50 may perform a function of calibrating if it is determined to be an error by referring to a signal of the surrounding sensor module 30, and storing and transmitting data related to the calibration. The sensor module 30 including a plurality of sensors may have a different lifespan according to an installed environment or individual characteristics. When it is determined that the specific sensor is deteriorated by sharing a signal between adjacent control units 50, calibration is performed. Of course, the final determination of the correction is responsible for the main control unit 50 in the situation room or control room (not shown) of each municipality. This correction data is stored and managed, meaning that it must be replaced if it occurs repeatedly.

The control unit 50 may further include at least one of a camera 35, a display 42, a microphone 44, and a speaker 46. The camera 35 is provided adjacent to the apparatus of the present invention to generate far-field and near-field images or various images. The display 42 outputs character / symbol information for promoting the operation of the control unit 50 or the value of the sensor module 30. The microphone 44 and the speaker 46 enable exchange of voice information between specific control units 50. In particular, the camera 35 makes it possible to control the shooting posture using a servomotor. Of course, the wireless communication unit 55 of the control unit 50 includes a transmission and reception function capable of bidirectional signal processing.

In operation, when a natural disaster such as fire, earthquake, radioactivity, yellow dust, toxic gas, etc. is detected in the sensor module 30, the control unit 50 transmits information to the control room and generates an alarm, but the situation room or control room After checking through the camera 35 and the speaker 46 may be stopped or enlarged. If there is a person in the vicinity of the disaster area, the alarm of the speaker 46 may be heard and an evacuation path may be set, and even a mobile communication impossible area may be used by using the network of the control unit 50.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
