In recent years, natural gas and oil prices have risen rapidly, and as a result, electricity costs have also risen sharply. rose. Government agencies or other organizations can reduce energy waste and Various efforts and programs are being made with the intention of developing efficient energy sources. has been raised. General consumers of electrical energy, especially general households and factory owners People are gradually becoming aware of the need to conserve energy.

However, despite the above situation, consumers of electrical energy It is not impossible, if not impossible, to easily and continuously check the amount of energy present. It is true that it is difficult. The cost of energy consumed is usually 1 power month Consumers are not informed until the total is released, and by the time the total is released, the electric energy has already been used. rugi are consumed and often paid. Notice of such final costs The delay in If you accidentally leave it on for a long period of time (this will be a problem).

Consumers can check their own power consumption by reading the meter readings regularly. Of course, it is possible to check the data and calculate the charges, but this kind of work is surprisingly difficult. This is cumbersome and therefore not a practical method.

Additionally, current systems include feedback controls that reduce, average, or cut off the hexagonal power. does not have a control circuit and therefore ceases to be used within the limits of the desired amount of energy. I can't do that.

Summary of the invention In one embodiment of the invention, utilities such as electrical energy, e.g. The usage cost of item i) is calculated and displayed to the consumer, and To provide a system for controlling the amount of utilities consumed over time. the system detects the utility flow rate consumed and provides a digital indication of utility usage.

Carantal circuit accumulates pulse streams to indicate current energy usage Provides display signals. The lock generator circuit uses a digital signal to indicate real time. The real-time pulse stream is cumulative to the time counter circuit. It is also shown on the display unit.

The computer circuitry responds to the energy usage count and time count7 and determines the current usage status ( Based on this, an estimated total amount is generated indicating the expected utility usage for the set period of time.

The comparator circuit sends a control signal in response if the estimated total amount is greater than the set amount. generate a number. This control signal can be used to issue an alarm to the user or to notify the utility. change the amount of energy used.

To explain the present invention with a more specific example, the amount of energy consumed by the system within a certain set period is It is equipped with an optical electronic circuit that monitors the amount of electrical energy being generated through an electricity meter. Equipped with

Accumulates the number of pulse digital signals within a set period using a microprocessor Performs digital signal processing such as counting.

A display unit is provided to numerically display the number of pulses during the set period. Also In another embodiment, the microprocessor described above is used to calculate energy usage. Calculate energy usage, convert it into an equivalent dollar amount, and estimate it over a given period of time. Calculate the energy price, compare the preset maximum price with the expected price, and if If the predicted price is higher than the set price, a control signal is generated.

The invention described above brings significant benefits to energy consumers. Consumers monitor Get up-to-date information about your energy usage with the ring system. I can do it. Data on accumulated energy prices are issued and displayed continuously. shown.

For a set period of time (estimated prices are shown to users at any time during that period) This allows users to instantly change their energy consumption to meet a predetermined budget amount. can be set. energy in the accounting period by using feedback control means. It is also possible to automatically change the energy consumption.

The flowchart is executed by a microprocessor to provide a predetermined output. It specifically shows the process by which this happens. These operating steps are applied to a hard-wired circuit. It is understood that even in this case, the same result will be achieved as described later.

The main processes of the microprocessor unit are shown in FIG. Figure 6 7 show the interrupt process, which is described in detail below. It operates simultaneously with the main program and changes the main program.

In FIG. 5, the parameters of the microprocessor are firstly reset signal I 3 (Figure 2), and the program will start immediately after being reset. Ru. When the parameters are initialized, the input/output ports are opened. next para Manually keying the meter into the microprocessor's memory (storage device) Desired: TIME indicating the current time, DATE indicating the current day, YEA indicating the current year. R, RATE, which indicates the current cost of energy, and the date on which energy usage aggregation begins. BILL DATE indicating the number of days in the month, DAYS indicating the number of days in the month, and the number of days within the aggregation period. BUDGET 0 is the maximum allowable cost for energy usage The BILL parameter indicating the current energy usage cost during the aggregation period will be described later. It starts with zero and is cumulative.

The next step is to determine whether the TIME UPDATE (latest time) flag is 0 or 1. It is to make a decision. If the flag is 0, the program starts the next set in the sequence. Toni move. If the flag is 1, the TIME parameter is incremented by 1 minute and sampled. to determine if the day has ended. Sequence if not finished move to the next set of When the end of the day is reached, the DATE parameter is 1 day. is increased and NEXT BILL (next bill) is calculated. This calculation is currently Based on the current usage amount for the period that has passed, the remaining amount of the aggregation period (1 month in this case) This is to calculate the cost of energy usage. The calculation formula used here is: It is as follows.

Finally, when the display key is pressed on the keyboard, the display selection flag is set and the process Return to start.

If no keys are pressed on the keyboard, the system enters an automatic display multiple sequence. Transition. TIME/BILL timer increases every 5 seconds and the TIME parameter and BILL parameters are displayed alternately. If the current display is B ILL parameter If the alarm flag is set in this case, the display will flash and the energy usage will be indicated. Warn the user that the limit has been exceeded.

Figure 7 shows a simple process for interrupting the latest bill. This sequence is completely A counting operation is performed when the energy cost reaches 1 kilowatt hour.

In the system according to the present invention, as shown in FIG. Each 256 DATA pulses perform. When the pulse count is finished, BILL UP The DATE flag is set and the path begins counting again. Shown in Figure 5 , when the BILL UPDATE flag is set, this is 1 watt at one time. This means that electricity was used during the period, and the total amount is calculated by dividing the current costs by 1,000. , then calculate that watt-hour by adding that amount to the current tally and collect Keep the totals up to date.

The only other interrupt operation in the system according to the invention is a manually performed interrupt. , in which case the keyboard is used. Keyboard interrupt signals are generated by key presses. input by line (72) σe which sets the flag.
