Abstract: A promising direction for the organisation of cooling systems in the agro-industrial complex is thermoelectric complexes built on the basis of thermoelectric modules. When developing and operating them, it is necessary to provide precise adjustment and correction of the operating modes of all distributed parts of the thermoelectric system for maintaining the microclimate in real time. This task can be solved by distributed telecommunication control systems. Based on the apparatus of Petri nets, a model of transport-level service for telecommunication management of thermoelectric systems has been developed. The interface of the transport layer and the scheme of the transport service data conversion module, including procedures for converting socket library data formats, have been developed. This ensures the integrity of the description of processes for establishing connections between environment objects and data exchange, as well as the compatibility of private models corresponding to subsystems with different levels of service services. A scheme for dispatching messages circulating in an ad hoc environment has been developed, which operates on the principle of priority queue. This scheme allows to deliver urgent messages in the most efficient and cost-effective way.
