Abstract
The invention provides a method for sensing a plant-related parameter in a horticulture space (115), wherein (i) a radio transmitter (151) and a radio receiver (152) are arranged such that a radio path (153) between the radio transmitter (151) and the radio receiver (152) passes through at least part of the horticulture space (115), and (ii) the radio receiver (152) is configured in a radio signal receiving relationship with the radio transmitter (151), wherein the method comprises a sensing stage comprising: emitting a radio signal with the radio transmitter (151); detecting the radio signal with the radio receiver (152) and providing a related receiver signal; and determining the plant-related parameter based on the receiver signal.
Claims10
A method for sensing a plant-related parameter of a plant in horticulture space, wherein (i) a plurality of radio transmitters and a plurality of radio receivers are arranged such that a radio path is formed between each of the plurality or radio transmitters and a corresponding one of the plurality of radio receivers such that each radio path passes through at least part of the horticulture space, and (ii) the corresponding one of the plurality of radio receivers is configured in a radio signal receiving relationship with each of the plurality of radio transmitters, the method comprising:
- emitting a baseline radio signal from each of the plurality of radio transmitters that passes through the plant during a baseline generation stage;
- detecting the baseline radio signal with the corresponding one of the plurality of radio receivers and providing a related baseline receiver signal during the baseline generation stage;
- sequentially emitting a radio signal with each of the plurality of radio transmitters that passes through the plant during a sensing stage;
- sequentially detecting the radio signal with the corresponding one of the plurality of radio receivers and providing a related receiver signal during the sensing stage;
- and
- determining the plant-related parameter based on differences between the related receiver signal and the baseline receiver signal during the sensing stage, the plant-related parameter including a leaf volume;
- wherein a radio frequency of the radio signal from each of the plurality of radio transmitters is in the range of 0.5 GHZ-5.0 GHz to detect said leaf volume;
- wherein at least one of the plurality of radio transmitters integrated in a first horticulture light generating device, and at least one of the plurality of radio receivers is integrated in a second horticulture light generating device.
A horticulture system comprising:
- a horticulture space,
- a control system,
- a plurality of radio transmitters, and
- a plurality of radio receivers,
- wherein each of the plurality of radio transmitters is arranged with a corresponding one of the plurality of radio receivers such that a radio path is formed between each of the plurality of radio transmitters and the corresponding one of the plurality of radio receivers and passes through at least part of the horticulture space;
- wherein each of the plurality of radio transmitters is configured, in a baseline generation stage, (i) to emit a baseline radio signal from the radio transmitter that passes through a plant, (ii) to detect the baseline radio signal with the corresponding radio receiver, and iii) to provide a related baseline receiver signal;
- wherein each of the radio transmitters is configured, in a sensing stage, to sequentially emit a radio signal that passes through the plant, and the corresponding radio receiver is configured to detect the radio signal and to provide a related receiver signal;
- wherein the control system is configured to determine a plant-related parameter based on differences between the receiver signal and the baseline receiver signal, and wherein the plant-related parameter includes a leaf volume;
- and
- wherein a radio frequency of the radio signal is in the range of 0.5 GHZ-5.0 GHz for detecting said leaf volume;
- and
- wherein at least one of the plurality of radio transmitters is integrated in a first horticulture light generating device, and at least one of the plurality of radio receivers is integrated in a second horticulture light generating device.
