Railway Speed Recorder Testing Equipment and Railway Tachometer Testing Equipment

摘要

The purpose of the present invention is a driving speed of the rail car, depending on the era of ever-increasing flow're inevitable The operation speed of a railway vehicle to advance its prevention, because it leads to greater risk, as well as braking and other important hameuroseo result by writing to handle the operation in accordance with regulatory requirements, allowing the characters to drive, the speed of the vehicle that may arise unhaengjung for the prevention of risks and conflicts lies in order to facilitate the safe operation of the vehicle. ; Thus, the subject innovation relates to a test device of the tachometer and the speed indicator that is installed in the cab, and more specifically is mounted on the axle caused by the generator driven according to the rotation speed of the axle is an apparatus for testing a tachometer which receives various operation conditions as the recording and storage of the vehicle is transmitted as a speed indicator and the additional write signal indicative of the speed, and is compatible with respect to all models, the height of the axle when the railway car test mobile transportation equipment provided with a free height of the air (Air) wheel which can vary depending on the test device is a plan of the convenience in use. ; intended for this is the standard specification in accordance with the test method Automatic testing according to automatic test according to your settings and functions largely divided into three types, including manual test according to your settings, as additional recording signal input feature 16 different variety of driving conditions, vehicle number, enter the 5-digit function, the current date, current time, to the test 10 times as the number of iterations and the correction made to the multi-input function (Multi) switch portion and the board input device, the motor drive of the measuring device as an input device in accordance with the set dwan value from a pulse width modulation (PWM) method to control a microprocessor (Micro Processor) unit, a frequency converting the frequency signal into a voltage voltage converter (FVC) unit, a frequency voltage converter (FVC) and parts of input voltage from the pulse-width modulation (PWM) Coupling as in the motor constant and a motor driving unit for driving the motor according to the voltage of the size, and the motor is controlled according to the rotational speed of the motor drive signal, by detecting the number of revolutions of the motor to be transferred to the microprocessor (Micro Processor) required for (Coupling) is an encoder (Encoder) which rotates, by detecting the rotation speed of the generator speed microprocessor (Micro Processor) and the analogue-digital converter (ADC) unit generator (Generator) to be transferred to the portion, the generator (Generator) unit and a speed indicator for indicating speed and recording system to record this speed according to the speed of the speed generator, and the output terminal of the generator speed, with tachometer box body for connection to the output terminal of the apparatus, abnormality of the motor and the generator speed and a self-diagnostic unit to determine, backup memory for storing the measured data (Back-up Memory) unit, according to the input value and the current progress, output values and a display unit for displaying various kinds of operation to determine the state, the and an output unit for the device to be copied via the print values, and real-time (Real Time) unit to support accurate current measurement time, and an alarm (Alarm) indicating the end of the measurement unit, the remote unit yirueojim (Remote System) characterized.
