Transmission module software for the digital technology in agricultural production

Wide spread of high-intensity robotic crop production, will allow to reach self-sufficiency in food at the expense of local multi-storey agricultural complexes, using specially prepared mineral nutrient solutions instead of the soil of megacities, settlements in The far North and in the deserts and, that is, to use Urban agriculture (UA). There are three main components of the UA: vertical farm, negraneau the cultivation of plants and robotic crop production systems. All these components are based on digital technologies. One of these technologies - intelligent control robot hydromeliorative plants in artificial ecosystems "Hydrobot 1,0" is the digital technology of cultivation of crop production, oriented on the use in the GSH. This technology, like all other digital technologies, requires wireless data transmission over long distances. The purpose of the research is to select and adapt one of the known communication standards in relation to the conditions of agricultural production. In the section results and their discussion, it is noted that as a standard of data transmission from bots and sensors chosen LoRa standard at a frequency of 433MHz. It is noted that LoRa has significant advantages over cellular networks and WiFi due to the possibility of deployment of inter-machine (M2M) communications at distances up to 20 km and speeds up to 50 Kbit/s, with minimal power consumption, providing several years of battery life on a single battery type AA. In addition, it is noted that for the purpose of plant data collection, this standard is best suited: the amount of data is small, and therefore there is no need for high data rates, and data transmission distances with a highly branched network can ensure the availability of one repeater for the entire complex (greenhouses or the entire building when used in UA). Also in the network can be used and other devices that transmit data about the plant to the repeater, for example, mini-sheet sensors that measure transpiration from the plant leaf. The repeater collects data from all devices and transmits data to the cloud storage or any database on the Internet. Conclusions: selected and adapted to the conditions of agricultural production-the structure of data packets transmission standard from bots and sensors: LoRa at a frequency of 433MHz.
