DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display instruction by confirming a deviation between an actual indicated value actually indicated by a power meter or the like and a display indicated value when an image of the indicated value of the meter is displayed on a monitoring center or the like. The present invention relates to a measured value maintenance method and a measured value maintenance device for correcting a value.

2. Description of the Related Art In a building or the like having many tenants, the amount of equipment such as electricity, gas, water, etc. used by each tenant differs.
Therefore, in each tenant room, a meter to measure each usage amount is installed for the purpose of managing the usage amount, and the meter readings from all tenant rooms are converted into electric signals such as pulse signals and transmitted to the monitoring center. I was The monitoring center converts the transmitted electric signals into meter readings, calculates the equipment usage fee for each tenant, displays the calculation results on an image, prints out the results, and centralizes the usage. I was going. As such a centralized management system, there is an automatic building management system called “MELBAS” developed by Mitsubishi Electric.

However, since an electric signal indicating the meter reading is transmitted from each tenant room to the monitoring center using a communication cable or the like, noise is mixed in the electric signal during transmission and is generated due to the length of the communication cable. Due to the influence of the voltage drop of the electric signal or the like, a deviation may occur between the actual power consumption indicated by the meter and the power consumption transmitted to the monitoring center in the form of the electric signal.

[0004] When such a deviation occurs, the electricity rate paid by the tenant is affected, so that the reliability is lacking. Therefore, in order to ensure reliability, the deviation between the power consumption indicated to the meter and the power consumption transmitted to the monitoring center and displayed as an image is detected once a year and transmitted. The power consumption was corrected and the measured values were maintained.

FIG. 4 is a diagram showing a system for implementing a conventional measurement value maintenance method. In the figure, reference numeral 1 denotes, for example, a power meter installed in a tenant room in a building. The power meter 1 indicates power consumption in an analog system or a digital system, and converts the power consumption into a pulse signal. The data is transmitted to a building management device (described later) in the building via the communication cable 4.

[0006] 2 is a building management device that receives a pulse signal transmitted via the communication cable 4 and converts it into digital power consumption, and 3 displays an image of the digitized power consumption, A personal computer that calculates and stores and prints out the electricity bill from the power consumption, 13 is a transceiver that transmits the power consumption read from the power meter in the tenant room to the building management device 2 by voice, and 14 is transmitted by the transceiver 13. This is the transceiver on the building management device 2 side that receives the consumed power consumption.

Next, a conventional measurement value maintenance method will be described. First, one maintenance worker carries the transceiver 14 and goes to a building management room (not shown) to operate the personal computer 3 to display an image of the power consumption of each tenant. On the other hand, the other maintenance worker carries the transceiver 13 and goes around each tenant room in a predetermined order, reads the power consumption from the power meter, and sends it to the building management room with the transceiver 13 together with the room number of the tenant. Inform the waiting maintenance workers.

When the power consumption and the room number are transmitted, the maintenance worker compares the power consumption with the power consumption corresponding to the room number displayed on the image, and receives the power consumption displayed on the image. Modify the power consumption stored in the personal computer to match the power consumption. When the correction is completed, the maintenance worker in the building management room informs the maintenance worker in the tenant room via the transceiver 14 that the maintenance has been completed, and moves to the next tenant room.

[0009]

As described above, according to the conventional measurement value maintenance method, the maintenance worker transmits the read power consumption to the other maintenance worker in the building management room by using the transceiver to transmit the power consumption. Was working on a fix.
Therefore, if there was a place where radio waves could not be transmitted to the building management room due to the structure of the building, the maintenance worker moved away from the power meter to a place where radio waves could be transmitted and reported the power consumption.

As a result, there is a problem that a difference occurs between the time when the power consumption is read and the time when the power consumption is transmitted, so that the power consumption corresponding to the real time cannot be transmitted, and an accurate correction operation cannot be performed. Furthermore, since at least two maintenance workers are required, there is a problem that the operation efficiency of the personnel is poor in dividing the contents of the work.
