161 results about "TRICKLE" patented technology

TRICKLE was a file-forwarding service on the BITNET (EARN/NetNorth/GulfNet) network. When it was created, many sites in Europe only had access to BITNET or compatible networks, and not to the Internet. Therefore, there was a great need to access files that were available only on the Internet. The TRICKLE server allowed anyone on the BITNET-compatible networks to access hundreds of thousands of files from many popular FTP servers around the world.

Pot flower remote detection system with trickle irrigation device and camera

The invention discloses a pot flower remote detection system with a trickle irrigation device and a camera. A temperature and humidity detection device of the pot flower remote detection system with the trickle irrigation device and the camera is used for monitoring the temperature and humidity of the flower growth environment and the soil moisture; when the soil moisture is lower than a set value, the trickle irrigation device is automatically started to supplement water to the soil; the camera is used for collecting a flower image; the detected relevant data is uploaded to a background server via a wireless router and the internet; the background server analyzes relevant data; meanwhile, the data is transmitted to an expert terminal; an analysis result is transmitted back to a client terminal via the background server; the expert terminal proposes a cultivation suggestion according to the sent relevant data and transmits the cultivation suggestion back to the client terminal. The pot flower remote detection system with the trickle irrigation device and the camera has the advantages that a user can monitor the favorite pot flower in real time, the system and an expert can provide the scientific and reasonable cultivation suggestion according to the flower growth environment data, the water can be automatically supplemented by the trickle irrigation device to avoid the phenomenon that the flower is withered because the user forgets to water, and therefore, the flower growth period is greatly prolonged.
