Description

Detailed Description of the Invention

  The present invention is an electricity bill reduction warning system associated with power liberalization.

Change electricity usage by electricity consumers, that is, by electricity usage hours, seasons, days of the week, Saturdays and holidays (hereinafter referred to as seasons) and maximum demand electricity.
In addition, the unit price is changed in accordance with the purchase amount and purchase consumption form of the electric foreign merchandise purchased by electricity consumers,
In combination with each other, the power company sets a plurality of types of electricity price menus.
It is desirable that the electricity consumer compares the electricity price menu and selects the electricity price menu that provides the lowest price. (Hereafter, the lowest price electricity price menu to select is called the contract menu)

  In this electricity rate menu, the usage rate is changed according to the season of electricity, especially in the electricity consumption mode, so if you use the same amount of electricity, it is better to avoid using it at a higher rate. Electrical loads without time zone restrictions should be used when metered prices are cheap.

  In addition, when an electric consumer purchases electricity and an electric foreign merchandise, the electric price menu is based on a combination of the amount of electric foreign merchandise purchased and the form of consumption and the electric consumption. The selection process is complicated and time-consuming.

In Patent Literature 1, for various devices installed in a factory, in order to avoid exceeding the contract power, the power consumption amount for a predetermined time is predicted, and when the prediction exceeds the contract power, the priority is low. An invention for stopping the device is disclosed. This is to minimize the contract power by avoiding excess contract power and to reduce the basic electricity charge between the manager and the electric utility.

JP 7-274394 A

The invention described in Patent Document 1 is a device installed in a factory, so that the state of all devices can be easily grasped. However, if the operating state of the device to be stopped is unknown, the desired power consumption cannot be reduced. In addition, there are many variations in the form of power consumption among general households, and it is not theoretically applicable like factory equipment.
Furthermore, when applied to ordinary households, not only the fairness of each consumer is impaired depending on how to determine the priority order to be stopped, but also there is a possibility that even daily life may be hindered.

In particular, the usage rate of electricity is changed according to the season of electricity, so if you use the same amount of electricity, it is better to avoid using it at a higher rate. Electrical loads without time restrictions should be used when the metered rate is as low as possible.

Since the alarms according to the shut-off level are output regardless of whether there is an obstacle to the daily life of the electricity consumer,
Also, instead of the two-step recognition behavior of listening to the incoming ringtone of the email and then reading the content of the email, the first-stage recognition behavior is based on the difference in the sound type due to the sound of the alarm sound or alarm melody.
The task is to easily determine how much electrical load should be cut off and be able to practice quickly.

  Furthermore, the need to strengthen and promote energy conservation is increasing as each and every employee increases their willingness to save energy, such as in response to increasing energy consumption and global warming.

  Therefore, the present invention has been made in view of the above-mentioned problems, and further minimizes the consideration paid by electricity consumers, thereby further enhancing the energy saving awareness of each individual and contributing to energy saving of the entire society. It is an issue to provide.

In addition, if a home energy management system (HEMS) is constructed using information appliances incorporating digital communication technology, the status of individual devices in a general household can be grasped and controlled remotely. It is expensive to construct a HEMS from replacement equipment and existing equipment, and it still takes time to disseminate it to ordinary households. Therefore, it is an object to construct a simple system that is manually operated until then.

In order to solve such a problem, the electricity rate reduction warning system accompanying the power liberalization according to claim 1 of the present invention includes a server that can receive ED information from a smart meter installed in an electricity consumer, Based on the received information, information as a basis for selecting the lowest electricity price menu for the server according to claim 2;

Moreover, the electricity rate reduction warning system accompanying the power liberalization according to claim 2 of the present invention is:
Information obtained from the server of claim 1 for electricity consumers from a wide variety of electricity price menus, the amount of purchase and consumption form of electricity external merchandise,
Based on the above, it is possible to calculate and compare which electricity price menu is the lowest price for the electricity consumer, and to save the selection.

In addition, the electricity rate reduction warning system associated with the liberalization of power according to claim 3 of the present invention is expected to exceed the target upper limit of the price set by the electricity consumer,
How much electricity in what time zone based on the information obtained from the server of claim 1 of the electricity consumer, the purchase amount and purchase consumption form of the electric foreign merchandise, and the characteristics of the contract menu selected in claim 2 A function is provided for calculating whether the load should be cut off and outputting a corresponding alarm signal for each cut-off level.

  According to a fourth aspect of the present invention, there is provided an electric charge reduction alarm system associated with the liberalization of electric power, which receives an alarm signal according to a cut-off level output from the function of the third aspect, and the sound type of an alarm sound according to the level. It is easy to determine how much electrical load should be cut off by installing a device that is devised to change the sound and changing the difference between the sound type of the alarm sound or the alarm melody. It is equipped with a function that can judge and quickly implement blocking.

In addition, the electric charge reduction alarm system accompanying the liberalization of electric power according to claim 5 of the present invention is based on the alarm level-specific alarm signal output from the function of claim 3 and the contents, subject, and attachment of the mail according to the level.
