Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, when a natural disaster in the lifeline field where automatic meter reading such as water supply, gas, electric power, etc. occurs, pipeline breakage detection that investigates the damage situation such as water outage, gas outage, power outage, etc. for each house over a wide area The present invention relates to a management center apparatus in the system.
[0002]
[Prior art]
In recent years, in many water supply systems that supply drinking water to each house, an automatic meter reading system is used to manage the amount of water used in each house and to automate charge calculation and the like.
[0003]
In this case, in a general automatic meter reading system, the amount of drinking water supplied to each house is measured by an automatic meter meter provided for each house, and the meter reading result is sent to a water supply via a general public line. It is transmitted to the management center side of the station, and the water charge for each house is calculated on this management center side, thereby eliminating the meter reading work by the meter reader and reducing the meter reading cost and eliminating the meter reading mistake. ing.
[0004]
[Problems to be solved by the invention]
However, in the above-described automatic meter reading system, as a basic function, there is only a function of automatically performing meter reading and transmitting the meter reading data obtained by this meter reading processing, and therefore water breakage or the like occurs. However, there was a problem that it was difficult to detect this.
[0005]
Therefore, as a method to solve such problems, automatic meter reading meters have been developed that have a water break detection function that detects when water breaks occur. Because it is assumed that the detection results will be transmitted to the management center using a public telephone line for general households. At the same time, public telephone lines for general households are often disconnected.
[0006]
For this reason, even if water breakage is detected on the automatic meter-reading meter side, this cannot often be transmitted to the management center side, making it difficult to cope with water breakage caused by a large-scale earthquake. When a large-scale earthquake occurs and an accident such as a water outage occurs, after the earthquake occurs, manually investigate the site, write the survey results on a drawing, and collect the collected data There was a problem that it took a long time to recover because it was necessary to identify the location of water shut-off.
[0007]
As prior art related to such a problem, an “automatic meter reading system” disclosed in Japanese Patent Application Laid-Open No. 8-163262 and a “pipe breakage detection system” disclosed in Japanese Patent Application Laid-Open No. 9-23483 have been proposed.
[0008]
In the “automatic meter reading system” disclosed in JP-A-8-163262, as shown in FIG. 10, the data of the gas meter 103 provided on each consumer 102 side is transferred to the PHS master station 105 side via the PHS slave unit 104. By processing the data obtained by each gas meter 102 by the center 106 connected to the PHS master station 105 side, the labor and cost of installing the equipment are reduced, and the communication cost is reduced. ing.
[0009]
Further, in the “pipe break detection system” disclosed in Japanese Patent Application Laid-Open No. 9-23483, as shown in FIG. 11, each pipe 111 constituting the pipe network 110 has a wireless communication function and a water leakage estimation function. Intelligent sensors 112 are installed, and each sensor 112 cooperates with the adjacent sensors 112 to detect water leaks in a distributed manner, transmit the detection results obtained thereby, and the communication device on the management center 113 side 114, the detection result is received, an alarm is generated, and the monitoring person 115 is informed of water outage, and on the basis of the water leakage information, the water distribution control device 116 remotely controls each valve, whereby the pipeline 111 is broken. When this is detected quickly, the worker 117 is informed of the damaged part of the pipeline 111, and the water-dissipated part is restored at an early stage so that the water pipe network or gas pipe network can be recovered. Which life line network to be maintained in the normal state.
[0010]
However, in the technology disclosed by the “automatic meter reading system” disclosed in Japanese Patent Application Laid-Open No. 8-163262, each PHS uses the parent-child communication function possessed by each PHS slave unit 104 and the PHS master unit 105. Since the slave unit 104 only has a function of transmitting the data of the gas meter 103 to the PHS master unit 105 side, it is difficult to increase the distance between each PHS slave unit 104 and the PHS master unit 105, and a large-scale earthquake occurs. When it occurs, there is a problem that it is impossible to detect whether the water pipe is broken over a wide range.
[0011]
Further, in the technique disclosed by the “pipe break detection system” disclosed in Japanese Patent Application Laid-Open No. 9-23483, when water leaks from a part of the pipe 111 due to an earthquake or the like, the pipe 111 of the pipe network 110 is used. A plurality of sensors 112 arranged on the top exchange data with each other, estimate the location of water leakage, and transmit the estimation result to the management center 113 side. There is a problem that the cost of the system is increased by that amount.
[0012]
In view of the above circumstances, the present invention can quickly and automatically specify a location where a pipe line is broken over a wide range without manpower, thereby enabling quick first aid and restoration work. It is an object of the present invention to provide a management center device in a pipe breakage detection system capable of performing the above.
[0014]
