Abstract
A fluid leakage detection system includes a detection device, a communication device, and a power supply unit. The detection device includes a detector that detects a leakage of a fluid from a flow path. The communication device includes a communicator to transmit and receive, to and from the detection device, predetermined information as to whether there is a leakage of the fluid. The power supply unit supplies power to the detection device in a wireless manner.
Claims14
A fluid leakage detection system comprising:
- a detection device including a sensor and a first electronic controller configured to detect a leakage of a fluid from a flow path;
- a communication device including a communicator configured to transmit and receive, to and from the detection device, predetermined information as to whether there is a leakage of the fluid;
- and
- a power supply unit configured to supply power to the detection device in a wireless manner,
- the flow path including
- a pipe, and
- an outer layer that covers an outer circumferential surface of the pipe, the detection device being arranged between the pipe and the outer layer.

A fluid leakage detection system comprising:
- a detection device including a sensor configured to detect a leakage of a fluid from a flow path;
- a communication device including a communicator configured to transmit and receive, to and from the detection device, predetermined information as to whether there is a leakage of the fluid, the communication device including a power transmission antenna configured to transmit a power supply radio wave to the detection device;
- and
- a power supply unit configured to supply power to the detection device in a wireless manner, the power supply unit being provided in the communication device,
- the detection device including a first detection device and a second detection device, the first detection device and the second detection device being arranged at different points in the flow path, and
- the power transmission antenna transmitting the power supply radio wave with directivity controlled so that an intensity of power to be received by the first detection device is higher than an intensity of power to be received by the second detection device.
