[Problem that the idea aims to solve]

By the way, from the perspective of stable energy policy, energy consumption by time of day and day of the week is important. It is necessary to know the different usage distribution accurately. To do this, draw a usage distribution curve It is necessary to collect the necessary information. In addition, recently, efforts have been made to use energy effectively. From the perspective of the service based on the premise, each consumer pays their energy usage fees fairly. The question is whether or not they are paying for it. For example, central heating systems with hot water For example, if a building is equipped with a There were offices that had little heating and mainly heated at other times. If so, the fee per unit amount of hot water used for heating at that office during that time period and other charges shall be paid. It would be unfair if the charges per unit amount of hot water used for heating in an office were the same. There is a case. In order to eliminate this inequity, it is necessary to create a fee structure based on time of day. In order to operate this rate system, it is necessary to calculate the energy consumption of each tenant or office depending on the time of day. It is necessary to know the amount of energy used.

[0007] In this way, it is important to implement stable energy policies and ensure fair services. needs to know the amount of energy used by time of day and day of the week. However, traditional inspection With the needle device, you can only check the cumulative value of the energy used up until now, and the above-mentioned There was a problem in the implementation of this attempt that made it impossible to contribute. Therefore, the present invention has been developed to perform integrated measurement by time of day or day of the week without complicating the configuration. The purpose is to provide a meter reading device that can also check values.

[0008]

[Means to solve the problem]

In order to achieve the above purpose, the meter reading device according to the present invention includes a plurality of measuring instruments and a meter reading device according to the present invention. multiple correspondences for each of these scales or for a specific scale. For the remaining scales, there are multiple scales, and for the remaining scales, there is one scale. multiple buffer memories that hold the integrated measurement values of the weighing instruments, and one weighing instrument. An accumulation period band is set for each of the buffer memories provided in correspondence with each other. The integration period band setting device to set each and the storage in each buffer memory for each measuring instrument. It is equipped with a meter reading board for reading the accumulated weight value held.

[0009]

[Effect]

The number of buffer memories provided in correspondence with each other in one measuring instrument is calculated as follows: For example, set it to 2, and use the integration period setting device to store one buffer memory during the daytime, for example in the morning. The accumulated weight value for the time period from 5 o'clock to 6 o'clock in the evening is held, and the other buffer Set the integration period so that the memory retains the integrated weight values for the remaining time period. By doing so, it becomes possible to accurately know the integrated metric value for each time period.

【Example】

Examples will be described below with reference to the drawings. FIG. 1 shows a meter reading device according to an embodiment of the present invention.

[0011] In the figure, 11a, 11b, 11c, etc. are provided for each customer and represent common measurement targets. A measuring instrument with a transmitting output for weighing is shown. These measuring instruments 11a, 11b, 11c The output ends of... are connected to three terminal devices 13a, 3 each via connection terminals 12a, 12b,... 13b,...

0012 The terminal devices 13a, 13b, . . . include four buffer memories 14a, 14b, . 14c and 14d are provided. Taking the terminal device 13a as an example, the buffer memory 1 4a and 14b are connected to the measuring instrument 11 via a gate circuit (not shown) and a connecting terminal 12a. a, and the buffer memory 14c is connected to the output terminal of the terminal 12a through the connection terminal 12a. It is connected to the output end of the measuring instrument 11b, and the buffer memory 14d is connected to the connection end. It is connected to the output end of the measuring instrument 11c via the terminal 12a. Similarly, terminal device 1 Buffer memories 14a, 14b, 14c, and 14d in 3b are also connected in the illustrated relationship. ing.

[0013] On the other hand, there is one meter-reading device located at a distance from the terminal devices 13a, 13b,... A board 15 is provided. This meter reading board 15 periodically or irregularly checks each terminal. Each buffer memory 14a, 14b, 14c, etc. is accessed by accessing the devices 13a, 3b, . 14d.

[0014] Each of the terminal devices 13a, 13b, . . . is provided with an accumulation period band setting device 16. ing. This integration period band setting device 16 is configured to each buffer memory 14a, 14b, 14. Of c and 14d, two buffers are provided in correspondence with one measuring instrument. It switches and controls the memory gate circuit, and includes the clock circuit 17 and the calendar circuit. 18 and a setting circuit 19. Now, only the terminal devices 13a and 13b are connected. For example, by operating the meter reading board 15, the buffer in the terminal device 13a is Provided at the input ends of the memory 14a and the buffer memory 14c in the terminal device 13b. For example, by opening the gate circuit only from 5 a.m. to 6 p.m. During the remaining time period, the buffer memory 14b in the terminal device 13a and the terminal device 13 Opening only the gate circuit provided at the input end of the buffer memory 14d in I can do that. Of course, settings can also be made at the day of the week level.

[0015] With such a configuration, the above-mentioned cumulative time can be set using the cumulative period band setting device 16. If it is set in advance in the band, the buffer memory 14a in the terminal device 13a is The integrated measurement value of the measuring instrument 11a is held during the time period from 5 a.m. to 6 p.m. . Similarly, the buffer memory 14c in the terminal device 13b is also stored from 5 a.m. to 6 p.m. The integrated measurement value of the measuring instrument 11f is held during the time period. Furthermore, the terminal device 1 The buffer memory 14b in 3a is used to store the totalizer of the measuring instrument 11a during the remaining time period. Similarly, the buffer memory 14d in the terminal device 13b also stores the remaining time value. The integrated measurement value of the measuring device 11f is held in the interval. And other buffer notes In other words, the buffer memories 14c and 14d in the terminal device 13a and the terminal device The buffer memories 14a and 14b in the storage 13b store the corresponding clocks regardless of the time zone. Holds the integrated measurement value of the meter.

[0016] Therefore, when the meter reading board 15 is operated, the measuring instruments 11a and 11f are The cumulative weight value for the time period from 5:00 to 6:00 p.m. and the cumulative value for the remaining time period. The calculated weight value is read separately, and for other weighing instruments, the accumulated weight value up to the current time is read out. will be read. For this reason, customers using the measuring instruments 11a and 11f It is possible to collect detailed metrological data by time of day.

[0017] In the embodiment described above, the specific measuring instruments, that is, the measuring instruments 11a and 11f We are trying to separate the integration time periods for the weighing scales, but we are also trying to separate the integration time periods for other measuring instruments. It's okay. In addition, the division of time zones is not limited to divisions such as daytime and nighttime, but also 24-hour division. The period may be divided into three or more, or may be divided by day of the week.

[0018]

[Effect of the idea]

As described above, according to the present invention, usage information of consumers by time of day or day of the week is provided. Since you can accurately know the information, you can implement stable energy policy and improve service. It can contribute to the implementation of attempts to level the playing field. Also, existing measuring instruments can be used as is. Therefore, it is possible to suppress an increase in the cost of the entire device.
