The article considers the principles of constructing and functioning the data collection and transmission system for developing an information and control system of an unmanned vessel. A problem of the information and control system developing is suggested in two stages: choosing methods and means of transmitting data from sensors to the data collection system, choosing the method of data transfer to the data collection system, implementing the data transmission channels; organizing data collection and storage for use in the autopilot device, implementing systems for receiving and synchronizing data and their placement in the storage system. There has been illustrated a block diagram of the information and control system for collecting and transmitting data for an unmanned vessel, which consists of two subsystems: data collection and data transmission. Selecting the main components and proposals on the software and hardware application is carried out. The detailed characteristics of the microcontroller, digital compass, microelectromechanical sensors and chartplotter are given. In the course of implementing the data collection system, a Maretron digital magnetic compass, CRM100 and CRM200 microelectromechanical sensors, which implement a yaw rate sensor and inclinometer, and an analog steering sensor were connected to the debug board. The software for the information and control system is written in the programming language using the STM32CubeIDE application development tools. It has been stated that the data transfer between different levels of the program is carried out using standard means of the program code.

The principles of construction and operation of the data collection and transmission system (DCTS) of an unmanned vessel are considered. A two-stage formulation of the problem of constructing a DCTS is proposed: the choice of methods and means of transmitting data from sensors to the data collection system, the choice of a method for transmitting data to the data collection system, the implementation of data transmission channels and, directly, the organization of data collection and storage for use in the autopilot device, implementation systems for receiving and synchronizing data and their placement in the storage system.

Abstract. The object of development is a device for multi-channel monitoring of the E1 stream state. The subject of the development is the monitoring of the status of the channels and analysis of traffic in each time slot of the E1 stream. The purpose of this paper is to develop an approach that allows multi-channel monitoring of the E1 stream state.
