Devices and methods for measuring and recording the operating modes of a locomotive during operation. Interuniversity collection of scientific articles. "Optimization board and improving locomotive nodes. "BelLIIZhT, Gomel 1979, p.45). The signal from the sensors of current, voltage, output of the racks of the fuel pumps, the speed of the crankshaft, as well as discrete signals are fed to the input of the information storage device. Based on the signals from the current, voltage, and speed sensors, the multiplier dividing unit calculates the tangential locomotive thrust force. The device allows you to register the following values: position of the controller of the driver; current and voltage of the traction generator;

speed and tangential traction of the locomotive; diesel engine rotational speed; output of racks of fuel pumps; current time.

The disadvantages of this device include: the complexity of processing the accumulated information due to the limited processing capabilities of the measuring information, the availability of consumables (registration tape), the limited number and large error of the calculated performance indicators of the locomotive, due to the low accuracy of the multiplier dividing unit. The components of this device are laboratory equipment and cannot be continuously operated as on-board locomotive devices. The design of the device does not allow remote transmission of the accumulated information, and also does not provide the possibility of its autonomous operation without an external power source.

Proceedings of the Institute "Improving the traction transmission of diesel locomotives and track machines", VNITI, Kolomna, 1982., p. 95). The input signals from the analog sensors are fed through the switch to the input

analog-to-digital converter, from the output of the analog-to-digital converter, the signal converted into a digital code is fed to the input of the control unit and recording signals and then to the measuring information storage device. The signals from the discrete sensors through the switch of the measuring signals are sent directly to the control unit and recording signals. On the board of the analog-to-digital converter, the measurement result of one of the analog channels is displayed. Information is stored on magnetic tape. The device allows you to register: diesel engine operating time, diesel engine operating time at each position of the driver’s controller, work performed by a locomotive for a period of 100-150 hours as a whole and at each position of the driver’s controller separately.

The disadvantages of this device include: limited functionality and the complexity of the subsequent processing of measurement results due to the lack of pre-processing and analysis of measurement information. The design of the device does not provide the possibility of its continuous operation on board the locomotive, as well as the remote transmission of accumulated information. The design of the device does not provide the possibility of its autonomous operation, without an external power source.
