Carry out dispatch instruction and personnel assignment efficiently, and based on this, support daily computerized daily output based on transportation cost analysis, safe driving management, vehicle management, driving status information and vehicle operation information. If you generate segment information using Global Positioning System (GPS) and Geographic Information System (GIS) information, and process the past and current speed information of the vehicle that has passed this section based on the generated information and send it to the central control center, Traffic information for each section can be calculated, and e-mail, Internet, and other information can be obtained through the porting of other communication programs. The present invention relates to an information terminal for an advanced vehicle capable of transmitting and receiving data.

In general, transportation logistics vehicles such as taxis and buses with a large number of passengers, vans and cargo trucks carrying loads are required to install a driving recorder to prevent traffic accidents and determine accidents in case of an accident.

In the conventional tachograph, data measured through a speed sensor, a fuel sensor, and an RPM sensor (engine speed sensor) as shown in FIGS. 1 and 2 are transferred to a computer operating program by a separate memory device or a small output RF device. The electronic speed recorder or the circular paper, which is transmitted and analyzed, is exchanged on a daily or weekly basis to record the daily speed on paper, but has been used independently by an analog tachograph.

However, in the case of electronic, it contributed to the computerization to some extent, but it was impossible to track the location of cargo and vehicle and to direct the remote dispatch due to the lack of functions such as location tracking and remote communication. Due to the difficulty of recording the contents of the call and the excessive communication cost due to frequent calls, it contributed to the increase of transportation cost.

In addition, there is little difference between the driving record and the management record due to the manual driving report creation, and there is little friction between the driver and the managerial staff. It was a cause of dropping, and there was a limit of service to customers because location tracking and cargo tracking were impossible.

On the other hand, tachographs that are recorded on paper are cumbersome to change papers, and the reliability of the data is degraded due to forgetting the time of exchange or the driver's manipulation of the needle. .

In addition, computerization of cost rises and analysis of recorded data is not possible at all, depending on imports, but only formally attached to legal aspects.

Therefore, in the case of both the electronic tachograph or tachograph, the driving daily must be prepared by hand, and various driving receipts (for example, fuel injection, expenses, travel expenses, allowances, repair expenses, etc.) must be submitted. The daily cost and various receipts were inputted into the computer, which made it possible to analyze the transport cost and the operation of the bus.

The conventional vehicle location tracking system has a general function of tracking the location of a vehicle through GPS and sending and receiving a message by an SMS communication method, which is a problem of SMS service in a mobile phone network. It is difficult to realize the accuracy of transmission and information transmission. Especially, due to the simplicity of the system from simple vehicle location tracking, the complexity of business cannot be satisfied, and the transportation cost analysis is more difficult due to the lack of the function of the tachograph.

In addition, the traffic information collection using the vehicle location tracking system can be used as traffic information only through frequent information transmission and modification of the transmitted data by the estimation algorithm in the server. There were many difficulties due to the accuracy of the information, the redundancy and inaccuracy caused by the error of the location information.

In addition, due to the failure to collect information about the driving status and the status of the vehicle itself, there are many problems in efficient driving management.In addition, with the development of information and communication, various functions of the Internet, email, and other information are not provided. The demand was not met.

Daily driving daily report is automatically based on daily operation input from driver as well as driving cost analysis and safe driving management, efficient management of personnel as well as driving status information and vehicle operation information, current location of vehicle, route of vehicle and cargo. It supports computerized output and generates section information using GPS and GIS information. It is possible to calculate the traffic information for each section, and to provide an advanced vehicle information terminal capable of sending and receiving e-mail, Internet and other information through porting of other communication programs.
