Abstract

PURPOSE:To facilitate electric power charge calculation by providing an electric power charge calculation processor having a storage unit for storing the occupancy ratio of tenants, a storage unit for storing the previous values of watt- hours and an arithmetic unit for calculating electric power charges from the current values of watt-hours, the stored occupancy ratio and the previous values of watt-hours. CONSTITUTION:When the floor areas of tenants A and B are (a) m<2> and (b) m<2>, a ratio calculating unit 2 calculates the occupancy ratios a/(a+b) and b/(a+b), respectively. The values of those ratios are stored in a first storage unit 3. A calculating unit 6 receives the values of watt-hours Pi from a read unit 5, the values of watt-hours Pi-1 from a second storage unit 7 which have been stored during calculating of previous electric power charges, the names of the tenants from the first memory unit 3 and the occupancy ratios of the tenants, then calculates the electric power charge of each tenant based on the unit price of electric power. As a result, electric power charges of the tenants A and B are represented by unit price X (Pi-Pi-1)/a(a+b) and unit price X(Pi-Pi-1)b/(a+b), respectively. Thus, charge calculation is facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electricity bill calculation processing device, and particularly to an electricity bill calculation processing device when one integrating wattmeter is provided for a plurality of tenants.

[Conventional technology]

Traditionally, this type of electricity bill calculation process involves calculating the total amount of electricity used by multiple tenants for a period from the difference between the previous and current readings using an integrating wattmeter, and calculating the amount of electricity used by each of the multiple tenants separately determined. A method that is often used is to allocate this total power consumption to each tenant according to the distribution ratio, and then multiply the unit price of electricity by the allocated power amount.

[Problem to be solved by the invention]

The disadvantage of the conventional electricity bill processing described above is that it is complicated, as it requires recording and storing the previous reading of the integrated wattmeter and the power usage distribution ratio in a ledger, etc., or performing calculations using a calculator, etc. There is.

[Means to solve the problem]

The electricity rate calculation processing device of the present invention includes an integrating wattmeter capable of obtaining an electrical measurement output, an input means for inputting a plurality of tenant names and the used floor area of each tenant, and input from this input means. a first storage means for calculating and storing the usage area ratio for each tenant; a second storage means for storing the integrated power amount of the integrated power meter when the charge was calculated last time; and the integrated power meter. and a calculation means for calculating and outputting an electricity charge for each tenant according to the usage area ratio from the difference between the cumulative power consumption and the cumulative power consumption stored in the second storage means and the usage area ratio. Consisted of.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, in which a keyboard 1. Ratio calculation section 2. First storage unit 3゜integrating power meter 4. Reading section 5. Arithmetic unit 6. It is composed of a second storage section 7 and a printer 8. The keyboard 1 is for inputting the names of tenants using one integrated wattmeter and their respective used floor areas, and the ratio calculation section 2 is for calculating the used floor area ratios for each of the input tenants. For example, if tenants A and B use floor areas of a m" and bm", respectively, tenant A will have a / a +
b, as tenant B b/a + b (7)
Do the calculations. The first storage unit 3 is a storage device that stores the above ratio calculated by the ratio calculation unit 2.

The integrated wattmeter 4 is capable of displaying the integrated amount of power used and outputting the integrated amount as electrical output. The reading section 5 reads the electrical output of the integrated wattmeter 4 in response to an instruction when calculating the electricity bill, and outputs it to the calculation section 6. The calculation unit 6 receives the integrated amount PI from the reading unit 5 and the current integrated amount P +- stored at the time of calculating the previous electricity bill from the second storage unit 7.
1, the tenant name and the used floor area ratio from the first storage unit 3, and calculates the electricity rate for each tenant based on the predetermined electricity unit price @.

That is, to quote the above example, tenant A has @×(PI
P'+-H) a/a+b, tenant B has @X (P
+ -P+-t)b/a+b is calculated. The results are also output to the printer 8 and typed out.

With the above configuration, if the tenant configuration changes, you can simply input the tenant name and used floor area from the keyboard 1 and give instructions when calculating the charges, and the electricity charges for each tenant from the previous time to the current time can be calculated. is obtained.

〔Effect of the invention〕

As explained above, the present invention allows a single integrating wattmeter to print out the distribution of electricity charges to multiple tenants based on the tenant's used floor area and automatic reading of the integrating wattmeter. This has the effect of eliminating the complexity of allocation calculation.
