<p>The proposed method is intended for operating a bidirectional packet switching radio network of guarded objects and working in the polling-response mode. The method is characterized in that a pre-assigned priority degree is encoded into the address of each object being guarded. The network control station, being provided with a data receiver, successively and repeatedly sends off addresses of the all objects being guarded along with a request for transmitting identification code of each object being guarded together with optional new data. The addressing frequency of each individual object being guarded is proportional to the priority degree thereof. Occurrence of alarm information in a certain guarded object of lower priority degree assigned thereto modifies address of that guarded object by encoding a higher priority degree in the address thereof.</p> |
