The solar cell 196 and the wind generator 194 is of a hybrid type.

As described above, the capacity shortage caused by using only the conventional solar cell 196 may be configured in a hybrid type with the wind generator 194 to supply stable power.

The solar cell 196 generates a power source by directly converting light energy of the sun into electricity using a photovoltaic effect, and has a constant voltage characteristic.

The wind generator 194 generates power by rotating the blades when the wind blows using the force of the wind.

The storage battery 192 is a battery that can be repeatedly charged and discharged, and is charged using the solar cell 196 or the wind power generator 194.

The optical sensor 180 detects light intensity and inputs a detection signal corresponding thereto to the controller 110.

The power supply unit 160 supplies the power supplied from the power supply unit 190 to the external device 200 and the control unit 110 of the sensing unit device 100.

At this time, the power monitoring unit 165 monitors the difference between the power supply of the solar cell 196 and the wind generator 194 supplied to the power supply unit 160 and inputs it to the control unit 110, the control unit 110 receives a control signal. In order to operate the power supply switching unit 170 to drive a stable constant voltage, constant current to the hybrid operation.

Store in memory not shown.

Looking at the operation of the configuration of Figures 1 and 2 configured as described above are as follows.

First, the power generated by the power supply unit 190 is supplied to the control unit 110 and the external device 200 through the power supply unit 160 through the power switching unit 170.

That is, when light of the sun is incident on the solar cell 196, electricity is generated by the solar cell 196 due to the photovoltaic effect, and when the wind blows, the wind is generated by the wind generator 194 using the force of the wind. Electricity is charged in the battery 192 using the electricity of the solar electricity 196 or the wind generator 194.

In connection, power is supplied to each component of the sensing unit 100 including the control unit 110 and the external device 200.

At this time, the solar cell 196 or the wind generator 194 is of a hybrid type, one is connected to the power supply unit 160, the other is connected to the storage battery 192 to supply a current to charge the storage battery 192.

In addition, the optical sensor 180 sends a detection signal according to the light intensity to the control unit 110, the control unit 110 determines the light intensity by the detection signal and turns on the aviation fault when the light intensity is weaker than the set value. Or flashes.

On the contrary, when the intensity of light is greater than the set value, the aviation lights are turned off.

The control unit 110 is also periodically or the data signal of the control command of the central server 300 is received via the transmit and receive antenna 150 from the neighboring sensing unit device or relay node, the control for its own control in the communication module 119 When the command is separated, the control signal is transmitted to the external device 200 through the external device connection unit 130 according to the control command.

The external device 200 operates by the control signal and inputs the result of the operation, that is, the information, to the information collection module 116 of the controller 110 through the external device connection unit 130.

When the external device recognition module 112 recognizes the operation of the external device 200, the controller 110 operates the external device sensing unit 120 to detect a state of the external device to determine a malfunction of the controller 110. Enter into module 118.

The malfunction determination module 118 determines whether the external device 200 corresponding to the detection signal is operating normally or not as a detection signal.

The information collected by the information collecting module 116 is added to the data signal received together with the determination result of the malfunction determination module 118 and input to the communication module 119, which the communication module 119 radios. It converts to be suitable for transmission and transmits to another sensing unit device or relay node neighboring through the RF transceiver 140 and the transceiver antenna 150.

The collected information and a malfunction determination result of the external device are stored in a memory of the controller and provided when an inquiry request comes from a neighboring sensor or a relay node.

If there is no control command for the data signal related to the control command of the central server 300 received through the transmission / reception antenna 150, the data signal is transmitted to the sensor unit or the relay node of the neighbor as it is.

When the data signal is transmitted to the end point relay node 400 in this way, the end point relay node 400 checks and verifies the final transmission contents of the start relay node through the backbone network, and checks the information of the transmission tower collected as described above. 300).

The central server 300 obtains necessary data (for example, wind direction, wind speed, and temperature from the transmission tower) by looking at the information of the transmission tower sent from the terminal relay node 400, and knows which external device or power supply of the transmission tower is broken. Can be.

The start relay node 400a generates data related to the control command and transmits the data to the first sensing unit device 100a.

When a reception occurs, the first detection unit device 100a checks the data signal related to the control command and wirelessly transmits the data signal to the second detection unit device 100b.

As described above, the transmission and reception are sequentially performed up to the end point relay node 400b.

When each sensor unit receives a data signal, it sends a response signal to the previous sensor unit that transmitted the data signal.

In addition, each sensor unit 100 collects information of the external device 200 when there is a control command related to the received data signal, and transmits the collected information to the data signal.

The end point relay node 400b checks and verifies the final transmission content of the start relay node 400a using the backbone network, and transmits the collected data to the central server 300.

In the above network configuration, when a failure occurs in the sensor unit, the network is operated as follows.

If the response of the next n-3 detector unit does not exceed the predetermined number of times (three times) after the transmission function is performed in the n-4 detector unit, it is determined that the n-3 detector unit is faulty or abnormal and the next time. An attempt is made to transmit to the n-th detection device.

In addition, the n-4 detector unit notifies the start relay node 400a and the end point relay node 400b when an abnormality is detected.

If communication with the n-2 sensing unit is not possible, the n-4 sensing unit operates a communication between the start relay node 400a and the end relay node 400b, and the endpoint relay node 400b operates as Attempt communication to the n-1 detection unit device to maintain the network.

This network information is transmitted from the start relay node 400a to the central server 300 through the backbone network in the central relay node 400b, and the central server 300 knows which transmission tower device 200 is broken. have.
