Abstract
Description
Technology Field
[0001] The present invention relates to a measuring device capable of measuring a signal of an integrated modular impulse track circuit device. Background Technology
[0002] A track circuit device is an electrical circuit installed for the purpose of directly or indirectly controlling various signaling facilities by using the rail as part of a circuit through which signal current flows and determining the presence or absence of a train based on the short circuit caused by the train's axle as it passes.
[0003] Currently, impulse track circuit devices are being used in the station premises of main railway lines, and there is now a trend toward switching to integrated modular impulse track circuit devices with improved functionality.
[0004] The integrated modular impulse track circuit device is equipped with a first-order transmitting module, a second-order transmitting module, a receiving module, and a track relay. Additionally, it consists of a transmitting and receiving impedance bond at the site. Although the voltage of the impulse track circuit that has been used until now could be measured using a multimeter equipped with an integrator, which is a conventional measuring device, when measuring the voltage of the transmitting module of the improved integrated modular impulse track circuit with this, the difference between the actual value and the measured value is too large beyond the margin of error, making it impossible to measure the accurate value. The problem to be solved
[0007] The purpose of this invention is to provide a track circuit measuring device capable of resolving the problems of the aforementioned conventional measuring device. means of solving the problem
[0008] While existing measuring instruments show only minute differences in measurement values between the transmission negative pulse and the arrival positive / negative pulse of the integrated modular impulse track circuit device, the transmission positive pulse shows a significant difference. Therefore, when a problem occurs in the transmission module, it is of utmost importance to accurately measure the value of the positive pulse emitted from the transmission module, and consequently, it is crucial to quickly and accurately determine whether the problem lies with the transmission module or the field equipment.
[0009] The signal value from the transmitting module is received through an analog data input sensor, and this data is programmed to convert it into digital data and display it on an LCD display, allowing for accurate measurement of the signal value. Effects of the invention
