[0026]
Further, the environmental monitoring device 12 can be connected to the central monitoring device 21 provided in the facility via the connection interface 16.
[0027]
The central monitoring device 21 is a device that manages supply and use management of energy resources between a supplier of energy resources and a facility that uses and consumes energy resources. For example, the amount of power used in the facility is managed by being supplied from the power company.
[0028]

[0034]
In addition, although not shown in the environment monitoring data memory 17, usage target data for each area, each energy resource, and the like that are created and input from past usage results for each energy resource generated by the environment monitoring device 12 are also stored. It is written and stored.
[0035]
Details of each processing sequence of steps S1 to S3 processed by the environment monitoring device 12 will be described with reference to FIGS.
[0036]
First, the usage amount detection processing sequence for each unit time and energy resource in step S1 will be described with reference to FIG.
[0037]
As described above, the environmental monitoring device 12 reads the meter reading data of the sensors 1 to n of the automatic detection areas 13a to 13n and the manual detection areas 14a to 14a from the manual input 15 in step S11. The current data at predetermined time intervals are input to the meter reading data of each meter 1 to meter n of 14n.
[0038]
The environmental monitoring device 12 waits until the input of the current meter reading data in step S11 is completed in step S12, and confirms that the meter reading data for each energy resource in all areas of the facility is input, in step S13. Based on the meter reading data for each energy resource for each current area for which the input was confirmed in the step 12, and the meter reading data for each energy resource for each area detected and input for a predetermined time or unit time before the current time. The usage amount is calculated for the predetermined time or for the unit time (hereinafter simply referred to as the unit time).
[0039]
The usage data for each unit time of each facility area and each energy resource calculated in this step S13 is the time of the current year in the area 1 of the environmental data memory 17 together with the meter reading data input time in step S14. Write and store the usage data for each day, day, and month, for each facility area, for all areas, and for each energy resource used.
[0040]
When the writing and storage to the area 1 of the environmental monitoring data memory 17 in step S14 is completed, the usage amount transition for each energy resource on the current day, this week, or the current month is compared with the target usage amount in step S15. Is displayed on the environmental monitoring status display 18.
[0041]
The usage amount transition for each energy resource for the current day, this week, or the current month generated in step S15 is the time, day, and day of the current year written and stored in the area 1 of the environmental monitoring data memory 17. It is generated from the usage data for each month, facility area, all areas, and energy resources used, and is written and stored in the environmental monitoring data memory 17 on the current day, this week, or the current month facility area Every time, we compare with the usage target data for each energy resource.
[0042]
From the comparison of the amount of use up to the present time in step S15 and the target value, in step S16, the facility area where the amount of energy resource used up to the present time exceeds the target value and the presence or absence of energy resources are determined. If it is determined that there is no facility area and energy resource whose usage exceeds the target value, the process proceeds to step S2, and it is determined that there is a facility area and energy resource whose current usage exceeds the target value. Then, in step S17, the facility area and the energy resource exceeding the target value are notified, the cause analysis and the execution of countermeasures are promoted, and the process proceeds to step S2.
[0043]
Next, the emission and emission amount detection processing sequence by the used energy resource in step S2 will be described with reference to FIG.
[0044]
The environment monitoring device 12 calculates the use in each facility area and each energy resource during the current unit time calculated in step S21 in step S21 and written and stored in the area 1 of the environment monitoring data memory 17 in step S14. Calculate emissions from the volume and the volume of emissions. As described above, the calculation of the emission for each energy resource and the emission amount of the emission is performed by calculating the emission per unit amount for each energy resource stored in the area 5 of the environmental monitoring data memory 17 in advance. The calculation is based on the type and emission data for each type of emission.
[0045]
The current emission data for each facility category and energy resource calculated in step S21 and the emission amount of the emission are written in area 3 of the environmental monitoring data memory 17 together with the current time data in step S22. Remember me.
[0046]
Next, in step S23, the emission for each facility area, energy resource, and emission data for each emission calculated in step S21 and written and stored in step S22 are preset. It is displayed on the environmental monitoring status display 18 in comparison with the target value. Next, in step S24, it is determined whether or not there is a facility area that discharges waste whose amount of discharge is greater than the target value for each facility area, each energy resource, and each discharge. As a result of this comparison and determination, if it is determined that there is no facility area that has more emissions and emissions than the target value at present, the process proceeds to step S3, and the facility area that has more emissions and emissions than the target value. If it is determined that there is, step S25 is executed.
[0047]
In this step S25, the facility area indicating the amount of emission and amount larger than the target value and the emission are notified, and the cause analysis and the execution of countermeasures are urged, and the process proceeds to step S3.
[0048]
Next, the energy resource usage status analysis and usage target plan creation processing sequence in step S3 will be described with reference to FIG.
[0049]
The environmental monitoring device 12 calculates in step S31 in step S31, and writes and stores it in area 1 of the environmental monitoring data memory 17 in step S14. At least the current day from the emission for each facility area, energy resource, and the like calculated at step S21 and written and stored in area 3 of the environmental monitoring data memory 17 at step S22. Or, for each facility area for each unit time up to the present time of the current week, the usage amount for each energy resource, the emission for each energy resource, and the transition data of the emission amount for each emission are generated.
[0050]
The transition data of the facility area, the usage amount for each energy resource, the emission amount for each energy resource, and the emission amount for each emission generated in step S31 are stored in the area 2 of the environmental monitoring data memory 17 in step S32. Compared with the past data written and stored in area 4, for example, for each facility area in the previous year and the year before last, the amount used for each energy resource, the amount discharged for each energy resource, and the change data for the amount discharged for each waste Is done.
[0051]
As a result of the comparison in step S32, if it is determined in step S33 that there are no facility areas, energy resources, and emissions whose transition data up to the present time is larger than the past transition data, the process proceeds to step S37.
[0052]
If it is determined in this step S33 that there are facility areas, energy resources, and emissions whose current transition data is larger than the past transition data, the transition data up to the present is displayed in step S34. Announce facility areas and energy resources and emissions that are growing more than data, and facilitate cause analysis.
[0053]
Next, in step S35, the current energy resource usage and emission emissions are determined based on the cause analysis analyzed in step S34, rather than the past usage of energy resources and emissions. It is determined whether or not the cause of the increase in transition is clear. Judgment of the increase in the amount of energy resources used and the amount of waste generated at this time is based on, for example, improving or changing the manufacturing method, manufacturing equipment, manufacturing content, etc. Although the amount increases, it is determined whether the reason for the increase or decrease of the energy resources for each area is clear, such as the amount of energy resources used in other areas is greatly decreased.
[0054]
If it is determined in step S35 that the cause of increase is clear, the process proceeds to step S37. If it is determined that the cause of increase is not clear, in step S36, the usage amount for each facility area and energy resource, Enter the conditions for creating a reduction plan with emissions. This reduction plan condition specifies the facility area where the cause of the increase in the current energy resource usage over the past usage trend has not been clarified, and the currently set energy of the identified facility area. Set and input conditions for changing resource usage plans.
[0055]
When the reduction plan creation condition input in step S36 is performed, in step S37, after the current time, the next day, the next week, or the following month, the creation of the usage target for each facility area and each energy resource is prompted, and the target is set. And end all processing.
[0056]
As described above, the environmental monitoring system according to the present invention divides the facility into a plurality of areas, detects the amount of energy resources used in each area at predetermined time intervals, By comparing the amount used for each energy resource used with the target value and past changes in the amount used, it becomes easier to predict the current state of consumption and future consumption, and the emissions for each energy resource used, By calculating and calculating the emission amount of the emission, it is possible to grasp the influence on the environment, and when there is a difference from the target value or past transition, it becomes easy to analyze the cause and create a countermeasure plan.
[0057]
