Abstract

PURPOSE:To eliminate the need for the patrol of a building for the purpose of periodic metering by applying a transmission request of a metering data from a monitor center installed at the outside of the building via a telephone line to a metering terminal equipment installed in the building and recording a data of the terminal equipment to the center automatically. CONSTITUTION:An electric installation 1 installed in a building 9, a gas installation 2, a water supply equipment 3 send a data to a CPU 7 of a building management equipment 5 via a metering meter 4 and store at a designation time by a clock 6 of a building management equipment 5 into a storage device 8. A monitor center 11 installed at the outside of the building uses a built-in clock 12 and a receiving-originating equipment 17 applies a data request to the building management equipment 5 via a telephone line 18 at a designated date. The building management equipment 5 sends the data stored in the storage device 8 to the monitor center 11 by a receiving-originating equipment 9 and the CPU 7 erases the data of the storage device 8. The monitor center 11 stores the data in the storage device 14, reads out the data from the storage device 14 at the designated date of receipt issue for each building and prints out the metering data and receipt by a printer 15.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a meter reading system for equipment in a building.

[Conventional technology]

In small buildings and tenant buildings, building management systems were installed, and managers visited each building to collect data recorded by this system.

Recently, building management systems have become increasingly unmanned by remote monitoring.

[Problem to be solved by the invention]

In the conventional technology, no consideration was given to unmanned management, resulting in the following problems.

The meter reading dates for electricity, gas, and water vary.
For example, the water supply service is used once every two months, and the other services are used once every two months. Furthermore, the storage capacity of the terminal side is limited, and data is erased after a certain time, so if you forget to read meter reading data, records may be lost.

In addition, since it is necessary to go to the site to manage the measured values,
The system is not suitable for unmanned management.

An object of the present invention is to automatically read and record measurement data on a terminal side from a monitoring center outside a building on a customer-specified day in meter reading for electricity, gas, and water, making it suitable for unmanned management.

Furthermore, the aim is to reduce memory on the terminal side, improve the efficiency of meter reading operations, and simplify management.

[Means to solve the problem]

The above object can be achieved by providing a device that automatically reads and records meter reading data recorded by a terminal device inside the building via a telephone line from a monitoring center outside the building on a date specified by the customer.

[Effect]

A monitoring center installed outside the building requests the meter reading terminal device installed inside the building to send meter reading data via a telephone line, and the data from the terminal side is automatically recorded at the center side.

This prevents an increase in memory capacity on the terminal side, and also eliminates the need to visit buildings for periodic meter readings.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

The electrical equipment 1, gas equipment 2, and water equipment 3 installed in the building 9 are connected to the CP of the building management device 5 through meter reading meters 4, respectively.
Send data to u7. This data is stored in the storage device 8 at a specified time by the clock 6 of the building management system M5.

A monitoring center 11 installed outside the building uses a built-in clock 12 to cause a receiving/transmitting device 17 to request data from the building management device 5 via a telephone line 18 at a specified date and time.

The building management device 5 that has received the data request sends the data stored in the storage device 8 to the monitoring center 11 using the receiving and transmitting device 9. Thereafter, the CPU 7 erases the data in the storage device 8.

The monitoring center 11 that received the data stores it in the storage device 14. Further, the clock 12 reads data from the storage device 14 at the bill issuance date and time designated for each building, and prints out the meter reading data and the bill 15.

This will be explained with reference to FIG. 2, which shows twisting without flow.

In steps 001 and 002, the meter reading date for each customer and meter, and the measurement pulse unit are set in the monitoring center 11 in steps 001 and 002. In step 101, it is checked whether it is a meter reading day or not. If it is a meter reading day, the telephone line is connected in step 003, and the terminal is called in step 004.

In step 005, terminal data is read and recorded. In step 006, the date and time data is checked, and in step 102, it is checked whether or not it is the invoice issue date. If it is the date, the current month's public usage of the building is calculated. (Step 007) Proceed to step 008 and record in the usage ledger file 14c. Next, the amount to be billed for usage by tenant and meter reading item is calculated and recorded in the bill ledger 14d in step 01.0. In step 011, a bill is created.

According to this embodiment, since meter reading data can be automatically aggregated from the monitoring center on a set date, it is possible to eliminate omissions in meter readings and to suppress an increase in memory capacity on the terminal side.

Furthermore, it has the effect of reducing the amount of work the administrator has to do for each building on each meter reading date.

〔Effect of the invention〕

According to the present invention, since meter reading data for each building can be recorded periodically and automatically at an external monitoring center, it is possible to suppress an increase in memory capacity on the terminal side, and it is also possible to prevent forgetting to read meter reading data. be.

Furthermore, there is no need for managers to visit each building to manage meter reading data, reducing administrative work.
