Claims

1. A wireless control system comprising:

a node apparatus comprising;

a power generating device,

a capacitor and a voltage conversion circuit device connected to the power generating device, and

a wireless device configured to transmit a first wireless signal, and connected to the voltage conversion circuit device;

a gateway device configured to receive the first wireless signal transmitted from the node apparatus and transmit a second wireless signal;

a server device connected to the gateway device;

a receiving device configured to receive the second wireless signal transmitted from the gateway device; and

an actuator configured to operate by a signal sent from the receiving device,

the power generating device generating and supplying power with which the node apparatus operates, and

the actuator increasing or decreasing the power generated in the power generating device.

2. The wireless control system according to claim 1, wherein the power generating device is a power generating device which generates power by an oxidation-reduction reaction caused by water leakage, and

wherein the actuator stops the water leakage to reduce the power generated in the power generating device.

3. The wireless control system according to claim 1, wherein the power generating device is a power generating device which generates power by current generating bacteria, and

wherein the actuator controls an activity of the current generating bacteria to increase and decrease the power generated in the power generating device.

4. The wireless control system according to claim 1, wherein the power generating device is a power generating device which generates power by a photoelectric conversion element, and

wherein the actuator controls a state of the photoelectric conversion element to increase the power generated in the power generating device.

5. The wireless control system according to claim 1, wherein the power per time generated in the power generating device is smaller than power per time consumed by the node apparatus.

6. The wireless control system according to claim 1, wherein a transmission cycle of the first wireless signal transmitted from the node apparatus is controlled by an amount of the power generated in the power generating device.
