Description

{Method for collecting and providing bus information through a virtual bus driver terminal in a cloud server environment}

The present invention relates to the collection and provision of bus information through a bus driver terminal. More specifically, the present invention relates to the collection and provision of bus information through a bus driver terminal, and more specifically, by allowing bus driver terminal equipment to be received and operated through wireless communication in a cloud environment rather than a bus driver terminal, so that the bus driver terminal equipment is relatively upgraded rather than an advanced equipment. Collects and provides bus information through a virtual bus driver terminal in a cloud server environment that can solve the problem of service interruption due to failure of the bus driver terminal caused by frequent access to the storage device while providing inexpensive equipment. It's about method.

A bus information management system (BIS/BMS, Bus Information/Management System) is being built that provides bus operation information in jurisdictions, mainly in large cities such as metropolitan cities as well as regional large cities.

This bus information guidance system collects the location of buses in operation in real time from the traffic information center and generates traffic information such as estimated arrival time at the stop, current bus location by route, distance from the vehicle behind, transfer information, etc., and generates the generated traffic information. It is a system that provides information through each stop guide or to personal terminal users through the Internet network, etc.

Such a bus information guidance system has been proposed in various ways, including domestically registered patent No. 10-0847350.

Meanwhile, the stop guide installed at the bus stop in the bus information information system is a display device for displaying traffic information, and most of them are LED display devices or LCD display devices, and are constructed so that they can be operated by supplying commercial power due to their high power consumption. It is done.

Therefore, in order to build a new stop guide, there was a limitation that it was limited to a location where commercial power could be easily supplied or that it had to be built so that commercial power could be supplied at a high cost.

In relation to this, Republic of Korea Patent No. 10-1768210 (registered on August 8, 2017, title of invention: two-way bus information information terminal) states, “It is a two-way bus information information terminal provided at each bus stop, and information on route buses passing through the bus stop is provided. A touch screen screen that includes a displayed route bus information field and a complaint registration field where you can register a complaint; information on route buses passing through the bus stop is received from the traffic control center server and displayed in the route bus information field. A technical configuration including a route bus information management unit; and a civil complaint registration management unit that registers civil complaints entered through the civil complaint registration field on a government agency server; is disclosed.

In addition, in Republic of Korea Patent Publication No. 10-2016-0141114 (published on December 8, 2016, title of invention: bus information guidance system and guidance method), “information related to the bus is stored in the user terminal provided by the user using the bus. This relates to a bus information guidance system and guidance method to provide bus information guidance system and guidance method that can disperse passengers boarding buses that arrive at the same time or approach with a short time difference.

Meanwhile, in order to provide such bus information, basically, in order to provide accurate information to the bus information information terminal, an expensive navigation-type driver terminal is installed inside the bus, which has its own operating standard information and the driver enters the route number before starting the trip and then enters the driver terminal. Based on the GPS information attached to the bus, arrival and departure events at stops and intersection passing events are independently determined and transmitted to the collection server of the Bus Information Center.

Hereinafter, with reference to the attached drawings, Figure 1 according to the prior art will explain a bus information provision system and a bus driver terminal.

Figure 1 is a diagram showing the concept of a bus information provision system, and Figures 2 and 3 are diagrams for explaining a bus driver terminal according to the prior art.

In the past, bus drivers manually made announcements by pressing buttons, or the system was linked to door operation, so it was often inaccurate. To complement this, an automatic guidance method was developed. Initially, transmitters were mounted on telephone poles or road signs around bus stops, and when a bus passed, signals were received and announcements were made. However, it had the disadvantage of being difficult to maintain because a transmitter had to be installed at each stop.

To compensate for these shortcomings and increase accuracy, GPS is used in recent guidance systems. The GPS coordinates of the transit points for each route are entered into the vehicle device of each bus. When the bus passes a point where the GPS signal received from a satellite matches the pre-entered GPS coordinates, the information is delivered to the traffic information center in real time. Afterwards, the traffic information center calculates the road conditions and past travel times between the collected bus location and the arrival location and derives the estimated arrival time. This data is converted into visual and auditory data and delivered to passengers with the message, “Bus number ○○○ will arrive in a moment.”

Until the early 2000s, the performance of terminals installed on buses was not very good. At best, only the current station and the next station could be transmitted, and since the 2G data network was used, it took a long time for the information to be updated, and the GPS was frequently disconnected, so there were many cases where the system information did not match the actual information. In particular, the Ministry of Land, Infrastructure and Transport (collection of highway and national road traffic information), National Police Agency (collection of urban road traffic information and traffic enforcement), local governments (collection of traffic information within jurisdiction), and private traffic information business operators have individually established systems to provide information. The quality of information provided to citizens was low compared to the quantity. To improve this, the city of Seoul began building the Seoul TOPIS (Transport Operation & Information Service) Center in 2005. This center collects all traffic collected from Seoul's individual systems, including Seoul city's urban highway traffic information, bus operation information, transportation card usage information, National Police Agency traffic/video information, unmanned enforcement information, Korea Expressway Corporation highway information, fire and disaster prevention video, and traffic broadcasting. It is a comprehensive traffic information service center that links information and comprehensively operates, manages, and provides traffic conditions in Seoul.

Through the traffic information provided in this way, Seoul City began to establish scientific transportation policies, and as a result, it was able to secure an accuracy of about 95% by 2010. Since then, thanks to the development of the LTE communication network and various IT, Korea's current bus information system boasts the world's highest level of accuracy and convenience.

Meanwhile, Figures 2 and 3 are diagrams showing a bus driver terminal according to the prior art. The conventional bus driver terminal includes a central processing unit (10), an information storage device (20), a power supply device (30), and a plurality of expansion modules (40). , 50, 60) and an interface 70 that is electrically connected to sensors, communication, screen input/output, and other devices.

Here, a number of expansion modules (40, 50, 60) include on-board equipment (OBE), digital tachograph (DTG), and automatic passenger counter (APC).

In this conventional bus driver terminal, the information storage device 20 stores route data, stop data, bus operation data, DTG data, events, and GIS data, as shown in FIG. 3.

The components in this conventional bus driver terminal are basically in the form of a PC like a regular laptop and consist of a CPU, memory, storage device, and display unit (usually LCD), and external devices include GPS, door open sensor, route guide, and passenger counter. The device is connected via serial communication. In addition, the driver's terminal is running MS Windows, Linux, and Android OS installed.

However, in the case of such a conventional driver terminal, the bus base information downloaded from the bus information center is stored in the information storage device 20, which is a self-storage device, and the base information is continuously searched on a GPS basis while driving. Connection to the information storage device 20 occurs, and a problem has arisen that frequent failures of the information storage device 20 configured in the driver's terminal occur due to frequent access to the information storage device 20.

In addition, because the screen is drawn through its own program to display information on the display screen that the driver sees, the load on the central processing unit (10), which is a CPU, and a large amount of memory are required, as in a computer, and passengers board or disembark. It is connected to the open/close switch of the door, and the CPU of the expensive driver terminal determines whether the door is opened and closed normally at the stop location and violation situations such as leaving the door open, and transmits it to the bus information center through the communication unit connected to the interface 70. Based on the speed information of the GPS information, the speed limit of the node-link among the base information is judged by itself and the speeding status is transmitted to the bus information center, and the bus information center determines the speed limit of the bus in front of the bus based on the driving event information received in this way. The spacing information between the cars behind is calculated and transmitted to the driver terminal in the bus, and the driver terminal displays the spacing information between the front and rear cars on the display screen.

These conventional driver bus terminals not only have the expensive problem of CPU, memory, etc., but also storage devices, costing about 3 million won, and often have problems with service interruption due to problems with bus driver terminals due to frequent access to the storage device. There is a need to solve the problem
