METHOD OF TRANSMITTING DIGITAL DATA Russian patent published in 2015 - IPC H04L12/711 H04L12/729 

FIELD: radio engineering, communication.

SUBSTANCE: method comprises simultaneously transmitting useful data to multiple services with different characteristics; real-time adjustment and maintenance in the actual state a communication network using a central modem, using main and alternative communication routes to which are switched without losing further information on route search upon change in communication conditions and replacement of communication devices. The method includes reading from the central mode, a list of addresses of slave communication devices by determining the list of devices newly appearing and excluded from the network; selecting a suitable communication protocol for newly appearing devices. The method includes adjusting the communication protocol to minimise the time for reading useful data from the devices by grouping requests and responses into packets having a length close to the maximum buffer size of the modems of the communication network where the types of requested data are marked with flags; setting a priority for each type of useful data, transmitting parameters which are common for all devices by transmitting from a concentrator broadcast packets with subsequent verification of successful execution of the command by reading acknowledgment from each device and separately correcting parameters.

EFFECT: high reliability of data transmission.
