Description

[Technical field]

[0001] The present invention relates to a CO2 emission management system for construction vehicles that can easily and objectively calculate the amount of carbon dioxide (hereinafter referred to as "CO2") emitted from construction vehicles such as ready-mix concrete trucks from the actual traveling distance of the construction vehicle. [Background technology]

[0002] In recent years, the global warming phenomenon caused by CO2 emissions has come to be seen as a problem, and in the construction and civil engineering industries, reducing CO2 emissions from construction vehicles such as ready-mix concrete trucks has been positioned as an important environmental measure.

[0003] Various methods for calculating CO2 emissions have been proposed so far. For example, Patent Document 1 discloses an invention for a CO2 emission reduction amount calculation system that can objectively evaluate the CO2 emissions corresponding to the vehicle's traveling speed and traveling distance.

[0004] Simply put, the route section for rail travel is divided into multiple sections, and the average speed at the expected passing time for each section is calculated from the expected passing time if traveling by car. CO2 emissions are then calculated from that average speed, the CO2 emission coefficient for each speed, and the distance traveled for that section. This method makes it possible to calculate CO2 emissions that take into account the characteristics of automobiles, where CO2 emissions vary depending on the travel speed, and in particular, is able to calculate CO2 emissions that correspond to changes in speed caused by traffic congestion, making it possible to objectively evaluate CO2 emissions. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2012-14215 A [Patent Document 2] Patent No. 5864170 [Patent Document 3] JP 2007-207140 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the invention in Patent Document 1 was intended to numerically inform railway users of the amount of CO2 emissions when traveling by car, thereby raising awareness of the convenience of using railways and the importance of energy conservation, and also helping them realize their contribution to reducing CO2 emissions, and was not made for the purpose of calculating the amount of CO2 emissions from construction vehicles such as ready-mix concrete trucks.

[0007] In addition, the calculation of CO2 emissions takes into account driving conditions, such as changes in the vehicle's driving speed, which changes the amount of CO2 emissions, and does not take into account other driving conditions, such as sudden braking or sudden acceleration, which tend to result in large amounts of CO2 emissions.

[0008] The present invention has been made particularly for calculating the amount of CO2 emitted from construction vehicles such as ready-mix concrete trucks, and aims to provide a CO2 emission management system for construction vehicles that can easily and objectively calculate the CO2 emissions of a construction vehicle from the actual distance traveled, taking into account driving conditions such as sudden braking and sudden acceleration that are likely to result in large amounts of CO2 being emitted. [Means for solving the problem]

[0009] The present invention is a CO2 emission management system for construction vehicles using a construction vehicle operation management system including a data management server that accumulates operation data of a plurality of construction vehicles, a location information transmission application that transmits location information of each construction vehicle to the data management server, and an operation management web application that checks the operation data accumulated in the management server. The construction vehicle operation management system calculates an actual travel distance calculated based on the location coordinates recorded for each construction vehicle at a predetermined time, the fuel efficiency of the construction vehicle, and a set CO2 emission coefficient by the following formula (1) based on the fuel efficiency method. CO2 emissions = (mileage / fuel consumption) x CO2 emission coefficient … (1) This is characterized by calculating the CO2 emissions of each construction vehicle.

[0010] The location information transmission app can be installed on a communication terminal such as a smartphone carried by the driver of each construction vehicle.

[0011] Further, for the fuel efficiency of the construction vehicle, either the standard fuel efficiency set by the Ministry of Land, Infrastructure, Transport and Tourism or the actual fuel efficiency calculated based on the fuel actually used for the travel distance of the construction vehicle can be used.

[0012] In addition, the operations of the construction vehicle while it is traveling, such as one or more of sudden acceleration, sudden braking (sudden stop), speeding, and idling, and the number of times such operations are detected, and data regarding the detected operations is stored in the data management server to determine correlation with the actual fuel consumption, which can be used to evaluate the driving of each construction vehicle driver in terms of CO2 emissions.

[0013] At that time, the setting conditions for sudden starts, sudden braking, speeding, idling, etc. can be arbitrarily set, for example, sudden starts: when moving at 20 km / h or more for 5 seconds. In addition, the position information (coordinates) of the construction vehicle can be recorded in units of seconds or minutes, and the running speed and acceleration of the construction vehicle can be calculated and counted from that.

[0014] In addition, idling can be measured by using an acceleration sensor app on an electronic device such as a smartphone, and if the engine is running while the vehicle is stopped, the acceleration sensor can detect vibrations to measure the time the engine is stopped.

[0015] Furthermore, the actual amount of fuel used can be calculated by measuring the time and number of occurrences of sudden starts, sudden braking, speeding, idling, and the like, and the correlation can be confirmed.

[0016] For example, data can be accumulated from sudden starts: x times, sudden braking: x times, speeding: x times, actual fuel consumption l / m, etc., and the fuel consumption coefficient for each can be calculated. Note that the fuel consumption coefficient is a percentage of the standard fuel consumption set by the Ministry of Land, Infrastructure, Transport and Tourism.

[0017] In addition, the driving history can be counted for no violations, sudden starts, and sudden braking, and an evaluation rank can be set for each number of sudden starts and sudden braking from no violations, for example A, B, C, and the fuel efficiency coefficient can be set based on the actual data, such as A being 2 times, achieving eco-driving, and standard fuel efficiency x fuel efficiency coefficient x 1.2 times, B being 3 to 5 times, standard fuel efficiency x 1 times, C being 6 times or more, standard fuel efficiency x 0.8 times, etc. Note that it is also possible to set individual coefficients, for example, sudden starts: 〇 times = 1.1 times, etc.

[0018] This makes it possible to accurately and objectively calculate CO2 emissions from each driver's driving behavior, fuel efficiency coefficient, standard fuel efficiency, and actual distance traveled.

[0019] In addition, it is possible to record a history of sudden starts, sudden braking, etc. on the map every second, so the location, number of times, and time of the driver's violation can be known. Furthermore, by automatically creating hazard maps, they can be used to alert drivers and educate them on safety during morning meetings and safety training sessions. Effect of the Invention

[0020] According to the present invention, the actual travel distance calculated based on the position coordinates recorded for a construction vehicle such as a ready-mix concrete truck at a predetermined time, the fuel efficiency of the construction vehicle, and the set CO2 emission coefficient are calculated by the following formula (1) based on the fuel efficiency method. CO2 emissions = (mileage / fuel consumption) x CO2 emission coefficient … (1) This makes it possible to easily and objectively calculate the amount of CO2 emitted from construction vehicles such as ready-mix concrete trucks.

[0021] In addition, by detecting one or more of the following actions and the number of times the construction vehicle is moved while in motion, such as sudden acceleration, sudden braking, speeding, and idling, and accumulating data on the detected actions, and determining the correlation with the actual fuel consumption of the construction vehicle, the data can be used to evaluate the driving of each construction vehicle's driver in terms of CO2 emissions.
