Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention monitors a plurality of governors (pressure regulators) provided at various points in a fluid supply network for supplying a fluid, and collects governor information relating to the operation of the governor from the plurality of governors. The present invention relates to a governor monitoring system provided with possible information collecting means.

[0002]

2. Description of the Related Art As such a governor monitoring system, there can be mentioned a governor monitoring system provided at various parts of a city gas supply network.

For the purpose of stable supply of city gas to each area, a governor having a predetermined capacity is arranged at each predetermined position of the city gas supply network, and city gas supplied from the factory side at a high pressure is supplied to a medium pressure, Furthermore, while adjusting the pressure to a low pressure, it serves to stabilize the gas pressure of the city gas supplied downstream from the governor.

Such a governor usually has a function of adjusting the gas pressure between the primary side and the secondary side, a function of shutting off a gas flow path, and a function of detecting gas leakage near the governor. . Therefore, with these functions, for each governor, information such as whether the governor is in a shut-off state, governor leak information whether a gas leak occurs near the governor, and equipment provided in the governor. Power supply information of the governor whether or not power is supplied, primary pressure information which is a fluid pressure supplied to the governor, secondary pressure information which is a fluid pressure regulated and sent out from the governor,
While the opening degree information is obtained, such governor information is sent to monitoring means (comprising a monitoring computer system) provided for monitoring the governor, and monitoring in a normal form is performed. Will be

[0005] Monitoring in the normal state is useful for operation and maintenance management mainly for the purpose of good city gas supply.

[0006]

FIG. 6 shows an outline of a governor monitoring system that has been conventionally employed. Conventional governor monitoring is performed for each grouped governor. Such grouping is based on governor performance (medium pressure A2 and medium pressure B
The grouping according to 3) and the grouping for each region within the medium pressure B are typical.

Conventionally, the governor belonging to the group A2 of medium pressure is connected to a central command system 7 of a central command via a security radio 5, and a monitoring system using the central command system 7 as a core has been established.

On the other hand, the governor belonging to the medium-pressure B3 group usually collects this information for each governor station in each region on the basis of information obtained by an on-site inspection by an operator, and compiles the collected information by telephone line. 8, the maintenance of the city gas supply network is sent to monitoring systems 9 and 10 (which form the core of the monitoring means in the conventional system) whose main business is a local unit.

However, when the above-mentioned system is adopted, for example, when an earthquake occurs, it has been found that there are the following problems. 1. Since monitoring of the governor is performed for each group of governors, for example, a plurality of governor operating states generated due to the occurrence of an earthquake cannot be satisfactorily viewed in a centralized manner. 2 Conversely, if a system is established that has a governor that is currently being monitored and managed by each business unit, etc., which is currently divided into a plurality of groups, the amount of information that can reach the center of this system Are limited at the same time, so that accurate and prompt response is not possible.

Furthermore, if it is attempted to collect governor information sequentially for all governors having a large number of governors, it takes a certain amount of time, and an area where it is expected to be urgently damaged, such as when an earthquake occurs. Collection of governor information related to the above may be delayed, and it is practically impossible to determine when information collection in such an area is completed.

3 At the same time, when a disaster such as an earthquake occurs, unexpected failures (line disconnection, local equipment failure, etc.) may occur, but such information cannot be collected.
It is likely to be an obstacle to accurate situational understanding.

An object of the present invention is to provide a governor monitoring system which can solve the above problems and can respond quickly and accurately when an earthquake occurs.

[0013]

According to the present invention, a plurality of governors provided at various points in a fluid supply network for supplying a fluid are monitored, and the plurality of governors are related to the operation of the governor. As described in claim 1, the characteristic configuration of the governor monitoring system including the information collecting means capable of collecting the governor information is capable of collecting the earthquake information of the points corresponding to the installation positions of the plurality of governors. With the earthquake information collecting means, in the earthquake information collecting means, when earthquake information satisfying a preset earthquake mode transition condition is collected, from the plurality of governors,
An earthquake governor information collecting means for automatically collecting governor information according to the earthquake information collected by the earthquake information collecting means.

In this monitoring system, earthquake information (typically seismic intensity information) corresponding to the position where the governor is installed is collected by the earthquake information collecting means, and is associated with the position where the governor is installed. ) Etc. can be obtained.

The earthquake information collected in this way is compared with a preset earthquake mode transition condition, and when this condition is satisfied, the system transitions to a mode corresponding to the occurrence of an earthquake.

In this mode, the collection of governor information is performed under the governor information collection means at the time of earthquake, and the collection is performed in accordance with the earthquake information. For example, information is collected in order from the governor with the highest seismic intensity information. In this way, it is possible to grasp governor information in the order of priority with the occurrence of an earthquake, and it is possible to quickly respond according to the degree of urgency.

Further, in the above structure, the plurality of governors are grouped according to a predetermined standard, and the governor information is collected by grouping according to the group. Is preferred.

Governors to be monitored in the event of an earthquake are:
There are many, and their types, regions, etc. will be separated. Therefore, similarly, even when collecting governor information according to earthquake information, not only information is collected for each governor, but also for each governor group divided into a predetermined group,
By collecting governor information, it is possible to collect effective governor information with classification according to its model, region, and the like.

Further, as described in claim 3,
In the above configuration, in order to automatically collect the governor information, the collection order is automatically set for a plurality of target governors to be collected, and the governor of the plurality of target governors is plural times according to the automatically set collection order. Preferably, the information is collected automatically.

In the present application, automatic collection is performed based on earthquake information (for example, seismic intensity information). Here, the collection order is automatically set, and the governor information of the governor to be collected is collected. The collection is automatically performed a plurality of times in the above order. In this way, it is possible to collect governor information in an order based on a certain standard according to the earthquake information, and, for example, when the damage caused by the earthquake is severe, it becomes impossible to collect the governor information. In such a case, when the environment is sequentially restored and the governor information can be collected, it is possible to respond while automatically collecting the governor information. In this case, the processing may be performed for each governor group.

Further, in the above structure, the plurality of governors are divided into at least two groups according to a pressure regulation ability, and the governors belonging to one group and the governor belonging to one group are provided. It is preferable that the information communication with the governor information collecting means is via a telephone line.

Although the number of governors installed in the present invention is enormous, information communication using telephone lines is simple and inexpensive at present. By using an information communication network, it is possible to construct the system of the present invention simply and inexpensively, and in the system of the present invention, a relatively large number of governors can be targeted, and the monitoring accuracy is much more remarkable than before. Can be raised.

On the other hand, as described in claim 5,
A plurality of governors provided at various points of a fluid supply network for supplying a fluid are to be monitored, and information collecting means capable of collecting governor information related to the operation of the governor is provided. In the case of a governor monitoring system including a monitoring unit for monitoring each group, the system is provided with earthquake information collecting means capable of collecting earthquake information at points corresponding to the installation positions of the plurality of governors, and In the means, when earthquake information satisfying a preset earthquake mode transition condition is collected, from a plurality of monitored governors set across the groups, according to the earthquake information collected by the earthquake information collecting means. It is preferable to include a governor information collecting means at the time of earthquake which automatically collects governor information.

As described in the section of the prior art, in a situation where no disaster such as an earthquake has occurred, a gas governor group (for example, a medium-A governor group) of relatively high importance is targeted for gas. If monitoring of the supply network is sufficient, governors that are less important than this (eg medium B governors)
It is enough if it is subject to daily maintenance, and the monitoring system has been constructed in a separate system according to its purpose, and has been functioning sufficiently well until now. That is, individual monitoring means is provided for each group.

However, if a quick response at the time of an earthquake is targeted only to a governor group having a high importance, there may be a case where it is not possible to take an adequately appropriate response, and at the same time, a unitary response covering details. There is a problem. Therefore, in the processing of the governor information collection means during an earthquake, the collection of governor information between groups equipped with monitoring means is permitted, and monitoring is performed for almost all governors under the jurisdiction. Response is possible.

The governor information may include:
As described in, governor shutoff information, governor leak information, governor power related, governor primary pressure information,
Governor secondary pressure information, governor opening degree information, and the like can be targeted.

Also, as described in claim 7,
With respect to the governor information, temporal fluctuation of each governor information,
It is preferable that the regional spread of the temporal fluctuation is monitored. In the event of a disaster such as an earthquake, the operating conditions of individual governors change over time, so for appropriate grasp of such information, the temporal fluctuation of each governor information or the regional spread of temporal fluctuations Can be detected and monitored so that appropriate measures can be taken.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of a governor monitoring system 1 of the present application will be described below with reference to the drawings. As shown in FIG. 1, the system 1 of the present application monitors about 300 medium-pressure A governors 2 and about 2700 medium-pressure B governors 3 and monitors the medium-pressure A governor 2 at a position corresponding to the installation position of the medium-pressure A governor 2. , And a seismometer 4 which is almost the same. The monitoring target area of the governor monitoring system 1 specifically covers the city gas supply area of the applicant of the present application.

The medium-pressure A governor 2 and the seismograph 4 are connected to a central command system 7 via a wireless communication system 5 and a centralized data server 6.
A structure is adopted in which all information of the medium-pressure A governor 2 is collected at intervals of several minutes, updated to the latest value, and always obtains governor information in the latest state. This collection mode is a state of the black portion shown in FIG. FIG. 2 shows an operation mode of the system of the present application at the time of an earthquake. The horizontal axis shows items that occur with time, such as an earthquake, the start of an earthquake mode, the determination of a seismograph, and the setting of an earthquake mode. Indicates completion. Hereinafter, description will be made with reference to this drawing.

In FIG. 2, information collection on the seismometer 4 and information collection of a middle block, which will be described later, are performed through the wireless communication system 5.

On the other hand, regarding the medium-pressure B governor 3, the telephone line 8, the data collection device 9, and the general data server 6
Is connected to the backbone central command system 7 through the network. That is, the medium-voltage B governor 3 connected via the telephone line 8 can acquire the current information by issuing an alert to the data collection device 9 and collecting data from the data collection device 9 to the general data server 6. Have been.
As shown in FIG. 2, this information is taken in a later-described little block, and is a portion indicated by oblique lines. Further, the data collection device 9 and the output terminal 10
Is a part that functions as a monitoring means. In this system, monitoring of a governor under the jurisdiction is enabled.

Further, on the lower side of the centralized data server 6, in parallel with the above-mentioned central command system 7,
Desired information is configured to be able to be taken out at the output terminal 10 or the like belonging to each business headquarters that monitors the supply status of city gas, and the output provided at the branch office in each region via a predetermined in-house LAN 11. The terminal 10 can also retrieve information.

Information handled in this system 1 is information related to governor operation, and includes primary pressure information, secondary pressure information, opening degree information, shutoff information, leak information, governor power supply information, and the like of the governor. At the same time, with regard to these various types of information, we also cover information on those temporal fluctuations, or the regional spread of such temporal fluctuation information (information on the extent to which predetermined fluctuations have been reached). It has become something.

Further, as for each governor, these governors are configured to individually execute an automatic shut-off operation. For example, when an earthquake is detected, when a gas leak is detected near the governor, For example, emergency shutoff is automatically performed.

As for a plurality of governors to be monitored by the governor monitoring system 1, governors are classified into super blocks, middle blocks, and little blocks based on a condition regarding an installation area as a main grouping standard. .

Here, the super block means a company-wide block, and can be said to be a block for each supply area. The middle block can be said to be a block having a basic unit of the medium pressure B conduit network (blocking for the area where the pressure is controlled and managed by each medium pressure A governor). In addition, a little block means a blocking of the low pressure conduit network.

Regarding the blockage of these blocks, a separate remote blocker (not shown) is provided for each block with respect to the super block, and a unique block system is provided. On the other hand, the middle block is blocked by a remote blocking device (not shown) attached to the medium-pressure A governor 2. Further, the little block is shut off by a seismic isolation device (not shown) provided in the medium-pressure B governor 3.

With the above-described block configuration, the governor monitoring system 1 can handle the governor information of each governor individually, and can execute the super block unit, the middle block unit, or the little block unit. Therefore, a configuration capable of handling governor information is adopted.

The above is an overview of the governor monitoring system 1 of the present application. The feature of the governor monitoring system 1 of the present application lies in the function at the time of occurrence of an earthquake. Such an operation will be described below.

As described above, the system includes the seismometers 4 at various locations, collects and collects detection information from these seismometers, and converts the collected earthquake information into a database. Has been built. Earthquake information collection is a function of the earthquake information collection means A of the present application, which is mainly a seismic information collection function unit of a computer provided in the seismograph 4 and the general data server 6 for data collection, organization, and storage. 12 is constructed.

Further, the system changes the operation mode of the system from the normal monitoring mode to the earthquake mode when the earthquake information collecting means A collects the earthquake information satisfying the preset earthquake mode transition condition. And a mode changing means 13.

The conditions for shifting to the earthquake mode are as follows:
For example, when the little blocks are viewed as a unit, two or more little blocks whose SI values detected by the seismometer 4 exceed 30 kine are used.

In the transition from the normal monitoring mode to the earthquake mode, as shown in FIG. 2, the detection information from the seismometer 4 is continuously taken, and the governor related to the middle block is operated. The continuous acquisition of information is performed. The governor information thus captured is stored in the governor information storage unit 15. Of course,
This collection result can be output in real time by the central command system 7 and other output terminals 10.

Regarding the little block, the system 1 is configured to collect information on the medium pressure B governor 3 related to the little block according to the following mode. That is, an earthquake governor information collecting means 14 for automatically collecting governor information according to the earthquake information collected by the earthquake information collecting means A is provided.

The operation of the earthquake governor information collecting means 14 will be described in further detail. The seismograph obtained in relation to these blocks in units of little blocks with the shift to the above-mentioned earthquake mode is described. According to the measurement values of the fourth order, the little blocks are rearranged in descending order, and according to the measurement values of the seismometer 4, the governor information (operating status) of the medium-pressure B governor 3 is automatically collected in order from the block estimated to have the greatest damage. The governor information is collected in the governor information storage means 15 provided in the general data server 6. Naturally, this collection result can be output in real time at the central command system 7 and other output terminals 10. In this state, collection of governor information in the little block employs a so-called polling collection form.

Further, the collection of the governor information is performed by a seismograph 4
In the case of performing in descending order based on the measurement value of
The earthquake governor information collecting means 14 collects governor information again while keeping the collection order set once. In FIG. 2, these automatic operations are described as the first automatic operation and the second automatic operation for the little block.

Such automatic information collection is performed in an automatically set order with respect to all the little blocks, which are monitoring objects and exceed the preset measurement values of the seismometer 4.
As a result, for example, the function of the medium-pressure B governor 3 belonging to the little block is temporarily interrupted, and when the function is recovered, the predetermined information is appropriately collected in the second automatic collection of governor information. Is obtained.

As shown in FIG. 2, after the earthquake mode is completed, the mode automatically returns to the normal monitoring mode. Such a return is performed by the mode changing means 13 described above.

The main configuration of the governor monitoring system 1 of the present invention has been described above. The operation of the governor monitoring system 1 will be briefly described below with a lapse of time from the occurrence of an earthquake. 1 When the seismometer 4 detects an earthquake, it automatically shifts to the earthquake mode. This transition condition is based on the condition that there are two or more little blocks having an SI value of 30 kine. 2 related information of the medium pressure A governor 2
Automatically collected using. 3. Automatically determine the collection order of the medium-pressure B governor 3 based on the value measured by the seismometer 4. The collection order is set in descending order of the measured value. In this case, the information related to the medium pressure B governor 3 is collectively polled and collected, and the latest information is sequentially distributed to the entire company. With the configuration described above, in this governor monitoring system 1, the collected information of the system can be taken out by each business headquarters at intervals of several minutes, collected as appropriate as the latest value, and the collected contents can be shared in real time by any department. Becomes possible.
