Description

Method and mobile communication device for executing emergency call for help

The present invention relates to a method for performing an emergency call for help, in particular to a method for performing an emergency call for help to a mobile communication device on a train.

Train dispatching involves a series of complicated operating procedures covering personnel, trains and stations. Therefore, the efficiency of each link will affect the overall transportation efficiency and passenger experience. However, most of the current operating procedures on the train rely on the train dispatching device in the captain's room and the judgment of the practitioners. Once the practitioners leave the train dispatching device, they will not be able to receive dispatching instructions or respond immediately. Such a configuration not only causes a burden on the practitioners, but also fails to ensure the efficiency and safety of driving dispatch. With the development of computer computing and network technology, operational information and computerization have become urgent needs in the transportation industry. Therefore, there is a need for a vehicle dispatching control system and mobile communication device that can dynamically monitor and manage in real time, which can provide safe, rapid, and reliable vehicle dispatching and travel services.

In order to solve the above problems, the present invention proposes an integrated vehicle dispatch control system and mobile communication device, which can monitor and dynamically manage the transportation dispatch status in real time. Compared with the general manual operation, the train dispatching control system proposed by the present invention is informationized and computerized in many aspects such as train dispatching, inbound notification, broadcast communication and emergency intercom, so as to reduce time and space constraints. , Effectively improve the efficiency of driving dispatch and passenger experience.

The conductor of the train or the service personnel of the train is stationed in the conductor’s room for ticket checking, car inspection, etc., and when any incident occurs on the train, the conductor or service personnel of the train will go to the train where the incident occurred. When dealing with incidents at the aforementioned locations, if a passenger encounters an emergency in a car on the train and needs to send an emergency call to the conductor of the train or the service personnel of the train, due to the emergency walkie-talkie of that car Or the emergency button is usually connected to the train communication device installed in the conductor's room by a physical line. The conductor or train service personnel must return to the conductor's room to receive the emergency call or communicate with the passengers on the emergency intercom through the train communication device. , Even if some trains are equipped with warning lights or buzzers on each carriage to remind the conductor or train service personnel that an emergency call for help is in progress, the conductor or train service personnel must still move to the conductor’s room to pass the train The communication device communicates with the passengers on the emergency walkie-talkie side to quickly and fully understand the situation. In addition, some trains can even talk to other emergency walkie-talkies on the emergency walkie-talkies in each car. However, even if this function is provided, the train length or the length of the train cannot be guaranteed. The service personnel of the train can immediately understand where the emergency call is sent from the train as soon as the emergency call is sent.

The above-mentioned procedure of emergency help is obviously very limited in time and space, and it may even cause delays in handling emergencies. The present invention proposes a method for enabling train conductors or train service personnel to instantly handle emergency calls for help anywhere on the train, as well as related systems and devices, so as to improve the efficiency and safety of the overall train service.

FIG. 3 shows a schematic diagram of the operation of the driving dispatch control system 1A according to an embodiment of the present invention. According to the embodiment of FIG. 3, the driving dispatching control system 1A is similar to the driving dispatching control system 1 of FIG. 1, but additionally includes a sensing device 80. In an embodiment, the driving dispatch control system 1A includes a plurality of sensing devices 80. Each sensing device 80 can be arranged on a track close to a station, and respectively transmit an identification signal. The identification signal of each sensing device 80 is different, which is used for identification.

When the train TR is traveling and approaches a station (for example, less than a predetermined distance), the train dispatching device 70 of the train TR receives the identification signal of the sensing device 80 of the station. According to some embodiments of the present invention, the sensing devices 80 near different stations have different identifiers, so the train dispatching device 70 can confirm which station the train TR is about to enter based on the received identification signal. For example, the driving dispatch control system 1A can use radio frequency identification (RFID) technology for identification, which is not limited by the present invention.

According to some embodiments of the present invention, each sensing device 80 has a different identifier, and the train dispatching device 70 stores an identifier list. The train dispatching device 70 can use the received identification signal to look up the table to determine which station is about to be entered. According to some other embodiments of this case, the above-mentioned identifier list may also be stored in the central control station 10, the dispatching station 20, the site control device 30, or other equipment that can be coupled to the communication network 40.

After the train dispatching device 70 transmits the above-mentioned train inbound message to the train communication device 60, the train communication device 60 can perform the train broadcasting function to broadcast the inbound message to all passengers. In addition, the train dispatching device 70 can also transmit the message that the train is about to enter the station through the communication network 40 by voice broadcast such as the message of "Taipei Station 101 is approaching" to the train crew, station attendant or nearby construction personnel using the same radio communication group. The radio communication device of relevant staff sends out voice messages to make them know that the train is about to enter the station and make preparations in advance, so that relevant staff can wait for the train to pass and improve the safety of relevant staff. In addition, the relevant service personnel in the station can also prepare related work for travel services after receiving the voice message.

This mechanism has many advantages for automated driving, driving scheduling, and driving safety. Taking automated train driving as an example, once the train dispatching device 70 determines that the train is about to enter the station but there is no sign of deceleration within a certain period of time, the train dispatching device 70 can actively report to the central console 10, the dispatching station 20, the station control device 30 or the action Communication device 50 and other warnings. In some cases, if there is still no sign of deceleration, the train dispatching device 70 can actively decelerate or even activate the braking mechanism.

Taking train dispatching as an example, once the train dispatching device 70 determines that it is about to enter a station, the train dispatching device 70 can actively notify the central console 10, the dispatching station 20, and the station control device 30 to ensure that no other vehicles are parked on the track, or use This message dispatches the platform where the train can stop.

In terms of traffic safety, in the past, there was no call response mechanism before the train entered the station. For example, the station staff or construction personnel are equipped with communication equipment that can communicate with the communication network 40. Once the train dispatching device 70 determines that the train is about to enter a certain At the station, the message can be sent to the communication equipment held by the relevant staff or construction personnel of the station through the communication network 40 for warning. In this way, accidents caused by people staying near the track can be avoided.
