Each area AR of the energy map 61 shown in FIG. 9 is given a darker color as the amount of energy used in the electrical equipment 1 increases. This allows the administrator to easily grasp the amount of energy used in each area AR within the management range MR. Note that the support information generation unit 35 can also generate support information that indicates the amount of energy used in each area AR using a type of color, a numerical value, or the like, instead of the shade of color.

Further, in each area AR of the residence time map 62 shown in FIG. 9, the longer the residence time of the object 2, the darker the color. This allows the manager to easily grasp the residence time of the object 2 in each area AR of the management range MR.

That is, the manager can analyze the relationship between the energy use and the object 2 in units of areas AR in the management range MR, so that analysis can be performed effectively for energy saving and work improvement.

For example, when a production system including a plurality of electrical equipment 1 is not automated, energy consumption is often interlocked with the retention position of objects 2 such as workers, carts, materials, or products. In such a case, there is a high possibility that energy is wasted where there is a large difference in size in the same area AR. can.

Further, the support information generation unit 35 can add information indicating the average number of workers for each time period in each work area AG to the support information shown in FIG. As a result, for example, the manager can identify the work area AG that consumes a lot of energy even though there are few workers, from the support information shown in FIG. 12 . Thus, a manager can, for example, analyze the correlation between worker density and energy usage. The support information generation unit 35 can also generate information indicating the continuous residence time of the worker in each work area AG as support information based on the residence time map.

Here, an example of the method of generating the support information shown in FIG. 12 will be described. The support information generation unit 35 calculates the total residence time of all the objects 2 for each time period for each work area AG based on the residence time map information. For example, when the target object 2 is only the target object 2 ₁ , 2 ₂ , 2 ₃ , the support information generation unit 35 generates the target object 2 ₁ , 2 3 for each time period for each work area AG based on the residence time map information. Compute the sum of 2 ₂ and 2 ₃ residence times. As a result, the average number of workers for each time slot is calculated for each work area AG. The time period is, for example, a period per unit time, and can be changed by operating the operation unit 38 .

In addition, the support information generation unit 35 can calculate the amount of energy used for each time zone in each work area AG based on the energy map information. The support information generation unit 35 calculates the number of workers for each time period in each work area AG based on the average number of workers for each time period in each work area AG and the amount of energy consumption for each time period in each work area AG. Energy usage per unit can be calculated.

As a result, the manager can grasp the amount of energy used by each object 2 for each work process, and can take measures to save energy or improve work efficiency.

Here, a method of calculating the amount of energy used for each of the objects 2 ₁ to 2 ₃ will be described. FIG. 14 is a diagram for explaining a method of calculating the amount of energy used for each object according to the first embodiment; In the example shown in FIG. 14, only four areas AR ₁ , AR ₂ , AR ₈ and AR ₉ out of areas AR ₁ to AR ₄₂ are shown for ease of explanation.

The support information generator 35 first generates a dwell time map 74 for all the objects 2 ₁ , 2 ₂ and 2 ₃ from the dwell time maps 71, 72 and 73 for each of the objects 2 ₁ , 2 ₂ and 2 ₃ . For example, the support information generation unit 35 sums the residence times "50", "5", and "10" of the area AR ₁ of the residence time maps 71, 72, and 73, and calculates the residence time of the area AR ₁ of the residence time map 74. to "65".
