Voice alarm for train alarm signal and its control method {ALARM VOICE GUIDING DEVICE AND CONTROLLING METHOD FOR TRAIN}

The present invention relates to a train alarm signal voice guidance device and a control method thereof, and more particularly, when a warning signal is issued from a certain security device by comprehensively and continuously detecting whether an alarm signal is generated by various security devices installed in a train. In addition, the present invention relates to a train alarm signal voice guidance device and a control method thereof, by promptly and easily guiding the driver with a voice to quickly and easily grasp a security device that generates an alarm signal so that a quick response is made.

Typically, all trains are equipped with various train security devices for safely operating the train. For example, the ATS, the ATC, the ATP, the driver's dwelling device which prevents the driver's drowsiness, and the adjacent trains by wireless communication. A train protection device to prevent collisions between the vehicle, a door-to-door notification device that signals the driver to start the train by checking the mechanical and electrical doors after the doors are all closed, and the generator's generator is notified of abnormal output. Voltage alarms, ground alarms to indicate poor electrical insulation of the locomotive's power circuits, engine superheat alarms to indicate that the engine temperature is too hot for the locomotive, and brake air pressure at the rear of the vehicle By monitoring the wireless data communication, there is a rear train monitoring device to know the normal connection status of all trains. In addition, more security devices are continuously being developed and installed for the sole purpose of crew.

The various types of security devices continuously monitor and control the operation of each part of the train according to their respective functions, and when an abnormality is detected in the corresponding operation, an alarm is issued to inform the driver. However, the security devices of the existing trains use alarm sounds and alarms when an alarm is issued for the normal function of the corresponding trains. Depending on the situation or the condition of the driver, it may not be easy to know which security device has generated the alarm signal. In more detail, according to the type of the vehicle, the train has a train automatic stop device, a train automatic control device, a train automatic protection device, a driving boundary device, a train protection device, a departure notice device, and a voltage-free alarm. Device, ground alarm device, engine overheat alarm device, train rear monitoring device and many other security devices are installed, and depending on the type of vehicle, the type and location of installation are different. In addition, the alarms of these security devices alert only when there is a fault in each device or when normal driving handling has not been performed, so the frequency of operation is very low. Uneasy. Therefore, if the action according to the alarm is delayed, the security device that guarantees the safety of the train cannot be performed under the premise of quick response, and the emergency braking is required to stop the train. There was a problem. For example, in the case of the train automatic stop device, after the alarm signal is generated, it is usually required to take a countermeasure within 3 seconds. If the countermeasure is not taken within the prescribed time, emergency braking is applied to all trains to completely shut down the train. The vehicle must be stopped and reset before resuming operation. Since the concept of such a security device is similar in other security devices, if any device is not able to respond quickly to an alarm, there is a problem that security devices installed for the purpose of ensuring the safety of the train act as a driving obstacle.

The present invention is to solve the above-mentioned conventional problems, the object of the train when the alarm signal is generated from the various security devices installed on the train, train delay or secondary accidents caused by the lag or misjudgment of the train to prevent the occurrence of accidents An object of the present invention is to provide an alarm signal voice guide device and a control method thereof.
