Description

Bus Integrated Terminal System {BUS INTEGRATED TERMINAL SYSTEM}

The present invention relates to a bus integrated terminal system, and more particularly, to automatically update the latest database and / or application program (firmware) to a bus terminal using a bus control terminal terminal, and to perform wireless communication between the bus terminal and a stop terminal. The present invention relates to a bus integrated terminal system that provides information on arrival time of a bus in real time and provides voice guidance to passengers waiting for a bus at a stop through an external speaker of the bus.

There are buses, subways, taxis, etc. that are commonly used, but the use of subways has increased rapidly, but the area where the subways do not pass is still used for route buses including village buses. In addition, demand for buses is still high due to the expansion of bus lanes. In the case of metropolitan cities where subways are widely used, the number of subway lines is insufficient. In the case of cities and counties, the use of buses is absolute.

In general, the bus guidance broadcasting is performed by guiding voice information or advertising information of a stop to be stopped or an advertisement broadcast by using GPS position information of a vehicle and position information of a pre-stored stop. However, in this case, there is a problem in that the voice or text data must be frequently changed due to the change of the route of the bus, the change of the stop name, the change of the advertisement contents, etc. (see Patent Document 1 and Patent Document 2). Conventionally, memory chips of all vehicles are directly exchanged with memory chips that store the latest database and / or application (firmware), or notebooks having the latest database and / or application (firmware) are directly connected to the bus terminal to the memory chip. The stored information had to be upgraded, but this required a lot of manpower and work time.

On the other hand, in recent years, a bus arrival guidance system including an LED or LCD display is installed at a bus stop to provide information such as a bus destination and arrival time (see Patent Document 2). However, the arrival time information of the bus is transmitted from the bus through the wireless communication server of the bus control station to the corresponding stop. Therefore, the arrival time information is delayed due to excessive server connection problem, communication speed problem, and processing time in the server. There is a lot of errors such as. In addition, in the case of a congested stop, it is not easy to check such text information through an LED or LCD display, and in particular, a text guide only provides information to the visually impaired or the elderly.

Referring to FIG. 4, after storing the latest database such as bus stop information in the bus control center management server 500 (S410), the stored latest database is transmitted to the bus control terminal 300 through a wired / wireless communication network (S420). Check whether the database of the stop terminal 400 needs to be updated with the latest information (S430), and if necessary, update the latest database stored in the bus control terminal 300 through the wireless transceiver unit 340 and 440. Transfer to the stop terminal 400 (S440). Thereafter, when the bus enters the stop, the latest database stored in the stop terminal 400 is transmitted to the bus terminal 100 through the wireless transceivers 440 and 150 (S450).

FIG. 5 is a flowchart for explaining the guidance of bus stop information, bus route information, advertisement information, etc. in a voice and / or text in the bus integrated terminal system according to an embodiment of the present invention.

Referring to FIG. 5, after transmitting the stop identification number from the stop terminal 400 to the bus terminal 100 of the bus entering through the wireless transceiver 440 (S510), the transmitter 140 transmits the radio through the wireless transceiver 150. The bus stop identification number is recognized in the bus terminal (S520). Check whether the stop needs to be stopped as a stop on the bus line (S530), and if it is necessary to stop, the in-car speaker 180 and / or the external speaker 190 and the in-car display unit 220 of the bus terminal 100 are required. And / or guides stop information, bus route information, advertisement information, etc. through voice and / or text through the external display unit 230 (S540). In this case, the in-vehicle broadcast and the external broadcast may be transmitted simultaneously or at intervals of time, and voice and text may be transmitted together or separately. The wireless transmission / reception unit 150 of the bus terminal 100 and the wireless transmission / reception unit 440 of the stop terminal 400 may exchange operating information necessary for the current stop and the next stop.

Hereinafter, a detailed operation of the bus integrated terminal system according to an embodiment of the present invention will be described.

The bus terminal 100 mounted on the bus detects the GPS position information of the bus received from the satellite through the GPS receiver 110 and matches the position information of the stop on the bus route stored in the memory unit 120. ) Extracts the stop and advertisement voice announcement data stored in the memory unit 120 as MP3 sound and amplifies the voice conversion unit 160 into an amplifier. The stop and advertisement announcement broadcasts to the in-car speaker 180 and the bus destination announcement broadcasts to the external speaker 190. In this case, the in-vehicle speaker 180 and the external speaker 190 may be automatically controlled using the relay. On the other hand, along with the voice announcement broadcast through the character output unit 210 consisting of the in-vehicle display unit 220 and the external display unit 230 may also be a character guide broadcasts such as text or images. In this case, the in-vehicle display unit 220 may provide news, weather or traffic information, as well as a stop and advertisement guide, and the external display unit 230 may display a bus destination. A passenger having a smartphone with an application for providing arrival stop information by recognizing the voice announcement broadcast may know the arrival stop information through a pop-up message. If the GPS location information of the bus and the location information of the stop do not match, the broadcast proceeds along the route without broadcasting.

If there is a change in the bus route information or the like, a new database is registered in the bus control center management server 500 and transmitted to the bus control terminal 300 through the wired / wireless communication network. Thereafter, the latest database stored in the bus control terminal 300 is updated by transmitting directly to the bus terminal 100 through the wireless transceivers 340 and 150, or in the case of a simple update, the latest database is updated to the stop terminal 400. When the bus enters the stop after transmission, it is also possible to update by transmitting from the stop terminal 400 to the bus terminal 100. In the same way, the terminal application program (firmware) can be updated.
