Description

Device for recording the operating modes of a locomotive

The proposed utility model relates to devices for recording measured values.

A device for recording the operating modes of a locomotive 1, consisting of sensors of analog signals (current sensor, voltage sensor, position sensor of the racks of fuel pumps, speed sensor of the crankshaft of a diesel engine, wheel speed sensor), sensors of discrete signals of a multiplier dividing device, recording device type H320-9. The signal from the sensors of current, voltage, the 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 storage device, information. Based on the signals from the current, voltage, and speed sensors, the multiplier divider calculates the tangential thrust of the locomotive. The device allows you to register the following values: the 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 locomotive performance indicators due to the low accuracy of the multiplier dividing device. The components of this device are laboratory equipment and cannot be continuously operated as on-board locomotive devices.

The closest in technical essence is a device for recording the operating modes of a locomotive 2, including; its analog signal sensors, relay signal sensors, measuring signal switch, analog-to-digital converter, signal control and recording unit, and measurement information storage. The input signals from the analog sensors are fed through the switch to the input of the analog-to-digital converter; from the output of the analog-to-digital converter, the signal converted to a digital code is fed to the input of the control unit and records the signals and then to the measurement information storage device. The signals from the relay sensors through the switch of the measuring signals are sent directly to the control device and recording signals. The analog-to-digital converter displays the result of the measurement of one of the analog channels. Information is stored on magnetic tape. The device allows you to register: diesel operating time; diesel operating time at each position of the driver's controller; work performed by a locomotive for a period of 100-150 hours, in general 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.

The objective of the utility model is to expand the functionality by providing the ability to calculate additional performance indicators of the locomotive and simplifying the subsequent processing of measurement information by recording measurement information into the drive, processed information.

The technical result is achieved by the fact that a device for recording operating modes of a diesel locomotive, including sensors of analog and relay signals, the outputs of which are connected to the inputs of the switch of measuring signals, one of the outputs of which is connected to the input of analog //.
