Abstract

A sensor signal transmission system includes: at least one wireless sensor disposed in an equipment package and configured to sense at least one type of information; a gateway configured to receive the at least one type of information sensed by the at least one wireless sensor in a wireless manner, and convert the received information into at least one communication signal; a controller configured to control the equipment package by collecting the at least one communication signal input from the gateway; and at least one wireless power supply configured to supply power to the at least one wireless sensor in a wireless manner.

First claim

What is claimed is:

1. A sensor signal transmission system comprising:
a plurality of wireless sensors disposed in an equipment package and configured to sense at least one type of information;
a gateway configured to receive the at least one type of information sensed by the wireless sensors in a wireless manner, and convert the received information into at least one communication signal;
a controller configured to control the equipment package by collecting the at least one communication signal input from the gateway; and
at least one wireless power supply configured to supply power to the wireless sensors in a wireless manner,
wherein priorities are assigned to the wireless sensors, respectively, and
wherein a higher-priority sensor among the wireless sensors is disposed more adjacent to the at least one wireless power supply.

2. The system of claim 1 , wherein the wireless sensors comprise a control sensor, an alarm sensor and a shutdown sensor which are disposed more adjacent to the at least one wireless power supply than the other sensors among the wireless sensors.

3. The system of claim 1 , wherein the equipment package is a compressor, a gas turbine or a steam turbine.

4. The system of claim 1 , wherein the controller is configured to control the wireless sensors in a wire or wireless manner based on the at least one communication signal.

5. The system of claim 4 , wherein the controller is configured to transmit the at least one communication signal to a display device in a wire or wireless manner.

6. The system of claim 1 , wherein the at least one type of information comprises information about at least one of ambient temperature, moisture and context of at least one device to which the wireless sensors are attached, respectively.

7. A method of transmitting a sensor signal from an equipment package in which a plurality of wireless sensors are installed, the method comprising:
controlling a plurality of wireless sensors attached to at least one device, respectively, included in the equipment package to sense at least one type of information, and transmitting the sensed information to a gateway in a wireless manner;
controlling the gateway to transform the sensed information into at least one communication signal;
further controlling the wireless sensors based on the at least one communication signal;
controlling at least one wireless power supply to supply power to the wireless sensors in a wireless manner; and
assigning priorities to the wireless sensors, respectively,
wherein a higher-priority wireless sensor among the wireless sensors is disposed more adjacent to the at least one wireless power supply.

8. The method of claim 7 , wherein, in response to an error occurring to a wireless sensor among the wireless sensors or in response to attaching a new wireless sensor to a device included in the equipment package, the gateway is configured to change settings of the wireless sensor in which the error occurs or the new wireless sensor.

9. The method of claim 7 , wherein the wireless sensors comprise a control sensor, an alarm sensor and a shutdown sensor which are disposed more adjacent to the at least one wireless power supply than the other sensors among the wireless sensors.

10. The method of claim 7 , wherein the equipment package is a compressor, a gas turbine or a steam turbine.

11. The method of claim 7 , wherein the at least one type of information comprises information about at least one of ambient temperature, moisture and context of at least one device to which the wireless sensors are attached, respectively.
