Abstract

This invention achieves power fee reckoning in time sharing using the electric meter of single free rate of old types on the basis of original computer for power monitoring computers. The technical solution of the present utility model is taking out the pulse signals of pulse or electronic electrical meters of single free rate, coupling the signals to the receiving card in the computer, reckoning automatically the time sharing value of consumed power using EXCEL form-making program in computer after programmed with software and printing automatically the time sharing month report form of consumed power. The advantages are that it not only can achieve reckoning respectively the value of consumed power in three time sections (peak, valley and normal) but also make use of the original electric meters of single fee rate, saving mush expense and keeping the data of month report forms and printing out the forms.

Description

Electric charge time division counting method by computer

Technical field

The present invention relates to cross in the kind, utilize old-fashioned single rate pulse ammeter or single rate electronic electricity meter, in the power monitoring computing machine, realize the time-shared charge function at power monitoring.

Background technology

Shanghai Electric Power office is from March, 1997, implement commercial power " peak ", " paddy ", " putting down " time-shared charge, the electricity rates difference of three periods, promptly in electricity consumption peak period, electricity price is expensive, ebb (the lowest point period) period electricity rates are low, now be generalized to also time-shared charge of residential electricity consumption, yet the ammeter that all use time-shared charge must be special-purpose ammeter, and old single rate ammeter all need be changed, for an enterprise, a large amount of old-fashioned single rate ammeters are all changed, and burden is heavy economically, wastes also very big.

Summary of the invention

Purpose of the present invention is to utilize old-fashioned single rate ammeter, on original power monitoring computing machine, realize the time-shared charge function, scheme of the present utility model is, takes out the pulse signal of single rate pulse ammeter or single rate electronic electricity meter, is connected to the receiving card in the computing machine, through software programming, utilize the EXCEL tabulation function of computing machine, calculate the power use by time shearing value automatically, and print power use by time shearing moon form automatically, described software programming, it goes on foot to gather and is:

A, definition module also begins a sub process;

B defines three global variables and is used to read three moment (moment one, the moment two, the moment three);

C defines a case statement, is used for distinguishing automatically the affiliated period of current time, jumps into corresponding implementation;

D, definition is a subprocess constantly;

E, three today, value added three aggregate-values constantly constantly, and emptied value today;

F will install actual value and give one second constantly and see number;

G, constantly one today value equal the device actual value and subtract one second moment and see number;

H is with the same procedure definition moment two, the moment three subprocess;

L defines monthly settlement process;

M, to the end of month will install actual value give total last month the device value, and empty three sections aggregate-values;

N, the process in three moment is set in definition;

O draws a window, and the user can set three constantly by the input time number in text box.

Advantage is, can reach the power consumption that calculates three periods (peak, paddy, flat) respectively, can utilize original single rate ammeter again, saved extensive fund, and can preserve the data of moon form, and printed a moon form.

Embodiment

The present invention only needs on single rate pulse ammeter or single rate electronic electricity meter, takes out a pulse signal and is connected to the interior receiving card of power monitoring computing machine, and is poly-by the aforementioned software programming step, can be on single rate ammeter, and realization time-shared charge function.

Claims (1)

1, a kind of electric charge time division counting method by computer, it is characterized in that: take out signal in the arteries and veins of single rate pulse ammeter or single rate electronic electricity meter, be connected to the receiving card in the computing machine,, utilize the EXCEL tabulation function of computing machine through software programming, automatically calculate the power use by time shearing value, and print power use by time shearing moon form automatically, and described software programming, it goes on foot to gather and is:
