Description

  The present invention relates to a safe driving analysis / diagnosis system for educating safe driving by analyzing driving information data including position information of latitude and longitude obtained from a digital driving recorder.

  In general, operation records of trucks, taxis, etc. are obtained from a tachograph (operation recorder) which is a device that continuously records the three legal elements of time, distance, and travel speed. This tachograph is currently obligated by the Ministry of Land, Infrastructure, Transport and Tourism to be mounted on commercial vehicles (trucks of 5 tons or longer, taxis in ordinance-designated cities, large sightseeing buses, etc.) and chart paper for one year.

The introduction of this tachograph began in 1959, and the analog tachograph was most popular. However, this analog tachograph type has an old design and requires experience and intuition for analysis of chart paper. In addition, due to changes in the environment surrounding the transportation and delivery industry, it has become necessary to respond to new issues such as reduction of CO ₂ emissions and fuel consumption and efficiency of office work. Therefore, an operation management method that meets the needs of the times is now required, and switching from analog tachographs to digital tachographs is progressing.

  This digital tachograph has begun to spread around 1998 and is now becoming mainstream. In addition, digital tachographs can record operations by simply inserting a memory card into a vehicle-mounted device on the premise of data analysis and management by a computer.

  Furthermore, if it is a type designation device by the Ministry of Land, Infrastructure, Transport and Tourism, simultaneous management with the conventional analog tachograph is not necessary, and it continues to advance with changes in science and technology such as addition of communication function and GPS receiver installed. Yes. In addition, digital tachographs will continue to contribute greatly to the transportation and delivery business as a means of information management and utilization in the IT era.

  By the way, since the operation record obtained from the digital tachograph is digital data, the operation record data can be used to promote driving techniques such as eco-driving and safe driving guidance.

  Therefore, for example, in Patent Document 1 below, traveling data generating means for generating a plurality of types of traveling state data indicating the traveling state of the vehicle during operation that changes every moment, and traveling state data generated by the traveling data generating means A travel state data storage means for storing a heart rate data capturing means for capturing heart rate data indicating the detected heart rate of the driver, wherein the heart rate detection means further comprises: Further, as the data storage means, there has been proposed an operation storage device that associates and stores the running state data generated by the running state data generating means and the heart rate data at which the heart rate data is taken in at that time.

  This conventional operation storage device uses a digital tachograph to collect driving conditions such as speed, engine speed, and position, and also collects information on the driver's heart rate, thereby detecting driving when falling asleep. A warning can be given to the person in real time.

  However, since the conventional vehicle operation record evaluation apparatus can give a warning to a driving driver in real time, it can prevent a drowsy driving that leads to a serious accident such as a traffic accident. It is difficult for the driver to grasp the fact, and in order to grasp the fact, the data collected from each driver must be analyzed individually, which takes enormous time and cost. Therefore, there is a problem that it is difficult to provide education that leads to safe driving.

  In addition, operation information data including position information collected from a digital tachograph that records all movable days can be easily recorded on an onboard digital tachograph by an external storage device such as an SD card. There is also a problem that analysis software etc. that analyze the price is expensive and difficult to use, and has not been introduced in small and medium-sized transportation companies.
