<Operation of CO ₂ Emission Management System According to One Embodiment>
In the present embodiment, when the CO ₂ emission management system 1 operates, it is assumed that the picking work schedule storage unit 141 stores a picking work schedule, for example, as shown in FIG.

  In the picking work schedule of FIG. 4, the traveling order information of the forklift P in the area where picking work is performed is “area a1 in area A → area a2 → area a3 → area b1 in area B → area b2 → area b3 → area C. “Area c1 → area c2 → area c3” is stored, and as information on the number of products to be picked in each area, “10 products a1 in area a1”, “1 product a2 in area a2”, “area 6 items a3 in a3, 20 items b1 in area b1, 30 items b2 in area b2, 10 items b3 in area b3, 4 items c1 in area c1 "Individual", "Three products c2 in area c2," and "One product c3 in area c3" It is.

Processing when the CO ₂ emission management system 1 operates in a state where the picking work schedule is stored will be described with reference to the sequence diagram of FIG.

  First, when the forklift P starts to operate, the voltage measuring device 11 of the vehicle-mounted device 10 starts measuring the voltage value of the power consumed by the operation at a predetermined time interval (S1).

When measurement of the voltage value is started by the voltage measuring device 11, the CO ₂ discharged when the forklift P performs the picking operation in the CO ₂ emission calculator 12 of the vehicle-mounted device 10 based on the acquired voltage measured value. _Two quantities are calculated every predetermined time interval.

This CO ₂ emission amount is calculated by the following equation (1), for example.

[Equation 1]
CO ₂ emissions (kg.CO ₂ ) = electric consumption (Kwh) × CO ₂ coefficient (kg.CO ₂ / Kwh) (1)
Here, electricity consumption (kwh) = (measured voltage value) ² / R
CO ₂ coefficient (kg.CO ₂ / Kwh) = 0 to 1 coefficient (coefficient disclosed by each electric power company)
It is.

The calculated CO ₂ emission amount is acquired by the CO ₂ emission amount acquisition unit 142 of the vehicle management device 14, and is sequentially transmitted to the central management device 20 via the wireless antenna 15 (S2).

In the central management device 20, the CO ₂ emission amount transmitted from the vehicle-mounted device 10 is received via the wireless antenna 21 and recorded in the CO ₂ emission amount recording unit 221 (S3).

  When the forklift P starts to operate, the speed measuring device 13 of the onboard device 10 of the forklift P starts measuring the moving speed of the forklift P at a predetermined time interval (S4).

FIG. 7 is a graph showing the correspondence between the CO ₂ emission amount at a predetermined time interval recorded in the CO ₂ emission amount recording unit 221 and the work time information recorded in the work time information recording unit 222.

FIG. 7 shows the picking work of the product a1 in the area a1 in the area A → the picking work of the product a2 in the area a2 in the area A → the picking work of the product a3 in the area a3 in the area A with time. This shows the change in the amount of CO ₂ emitted in one cycle.

In next area-specific emission calculating unit 231, from the information CO ₂ emissions and the working time information associated with a predetermined time interval, CO ₂ emissions of each area A~C by picking operations is calculated.

The CO ₂ emission amount for each of the areas A to C is calculated by integrating the corresponding CO ₂ emission amount between the picking work start time and the work end time of each area.

The CO ₂ emission amount for each area A to C thus calculated is recorded in the area-specific emission amount recording unit 223 of the recording unit 22 of the central management apparatus 20 (S17).
