Background

In an equipment monitoring system that monitors the status of a plurality of pieces of equipment collectively, when an abnormality occurs in the equipment, it is necessary to promptly and accurately notify a maintenance worker or the like of the abnormality to restore the abnormality.

Japanese patent laid-open No. 8-227491 describes the following technique: a central monitoring device of a building management device has an in-building database which stores a floor plan of each floor of a building to be monitored and two-dimensional and/or three-dimensional data relating to the arrangement of equipment. Here, in the case of a fire alarm device whose monitoring target is 2 layers, for example, on the monitoring screen, the monitoring status is also displayed on the layout chart for 1 layer and 3 layers above and below the fire alarm device.

Japanese patent laid-open publication No. 2014-50096 describes the following system: in this system, the remote monitoring terminal can also perform operations of a keyboard, a display, and a mouse by using a central monitoring terminal of a building management system that manages building facilities. When an alarm is issued, an enlarged highlight monitoring screen mail of text data information of the alarm issuance site displayed on the remote monitoring terminal is transmitted to a relevant person registered in advance, and the relevant person who has received the mail calls the remote monitoring terminal to confirm the details of the alarm issuance site.

Japanese patent laid-open publication No. 2009-92594 describes the following techniques: a network (Ad-Hoc network) based on a short-range wireless communication means is constructed between a wireless device which cannot utilize GPS in a building and cannot know its own position information and a plurality of other wireless devices which can utilize GPS, and the own position of the wireless device is estimated.

In the related art, when an abnormality occurs in an equipment device to be monitored, the occurrence of the abnormality is reported to a relevant person by mail or the like, but the report indicates the contents of the abnormality by a fault code, a fault name, or the like, for example. Therefore, the person who receives the mail needs to inquire of a monitoring center or the like in order to obtain detailed information such as a place where the abnormality occurs.

Disclosure of Invention

An object of the present invention is to provide a facility monitoring system capable of coping with an abnormality of a facility to be monitored only by a mail or the like to be transmitted.

The instrument monitoring system of the present invention is characterized by comprising: a local controller that monitors the states of a plurality of pieces of equipment in a facility to be monitored, and determines a failure ID (identifier) assigned in advance to each piece of equipment when a failure occurs in the facility; a failure database that stores failure content names and configuration location information of the equipment instruments in association with the failure IDs; a plurality of operator terminals having a mail transmission/reception function; a mail server which transmits and receives mails to and from the operator terminals; and a management server connected to the local controller, the failure database, and the mail server, wherein the management server receives the failure ID from the local controller, acquires the failure content name and the arrangement position information of the equipment device corresponding to the received failure ID from the failure database, transmits the acquired failure content name and the arrangement position information of the equipment device to each operator terminal via the mail server, acquires a failure response reply from the operator terminal via the mail server, registers failure response operator information, and transmits the registered failure response operator information to each operator terminal via the mail server.

In the equipment monitoring system according to the present invention, it is preferable that the management server transmits, as the equipment placement position information, the wide-area placement position information on the building name and the building floor in the facility and the detailed placement position information on the building floor via the mail server.

In the equipment monitoring system according to the present invention, it is preferable that the wide-area arrangement position information and the detailed arrangement position information are image information indicating an arrangement position of the equipment.

In the plant monitoring system according to the present invention, it is preferable that the failure handling reply includes information on the current position of the operator terminal to which the reply is made.

In the equipment monitoring system according to the present invention, it is preferable that the management server acquires a trouble handling support reply from an operator terminal other than the operator terminal having performed the trouble handling reply via the mail server, registers support operator information, and transmits the registered support operator information to each operator terminal via the mail server.

The equipment monitoring system of the present invention has a management server connected to a failure database storing failure content names and configuration location information of equipment. When receiving a failure ID related to an equipment device, the management server acquires a failure content name and equipment device placement position information corresponding to the failure ID from the failure database, and transmits the equipment device placement position information together with the failure content name to each operator terminal. Each of the received maintenance workers can determine whether or not the job is to be performed by checking the failure content name and the arrangement position information of the equipment. Further, since the maintenance worker who has received the information can perform the trouble-handling reply when it is determined that the trouble-handling is possible, the management server registers the trouble-handling worker information and transmits the information to each worker terminal. In this way, since the information on the arrangement position of the equipment is transmitted, the maintenance worker can determine that the work can be dealt with only by looking at the information.

In the equipment monitoring system according to the present invention, the management server transmits, as the equipment arrangement position information, the wide-area arrangement position information on the building name and the building floor in the facility and the detailed arrangement position information on the building floor. Each of the received maintenance workers can view the name of the failure content and the detailed arrangement position information of the equipment, and therefore, the worker can deal with the failure content only according to the content.

In the equipment monitoring system according to the present invention, the wide-area arrangement position information and the detailed arrangement position information are image information indicating the arrangement position of the equipment, and therefore the maintenance worker who receives the information can quickly determine whether or not the work can be dealt with.

In the plant equipment monitoring system according to the present invention, the failure response reply includes the current position information of the operator terminal that has performed the reply, and therefore, by transmitting this information to the other operator terminal, the received other maintenance operator can determine whether or not support is available.

In the plant monitoring system according to the present invention, when a trouble response support reply is acquired from a worker terminal other than the worker terminal that performed the trouble response reply, the information is also transmitted to each worker terminal, so that all the relevant persons can share the trouble response event information.

Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Hereinafter, a wireless communication type portable terminal carried by a maintenance worker is described as an operator terminal, but this is an example for explanation and any communication terminal may be used as long as it has a function of transmitting an email with an image. For example, a desktop communication terminal that performs wired communication may be used. In the following, the hierarchical information for specifying the wide-area arrangement position information of the building and the floor and the detailed arrangement position information of the place on the floor is described as the arrangement information on the equipment, but this is an example for explanation, and when the scale of the monitoring target facility is small, only 1 type of arrangement information may be used, whereas when the scale is large, 3 or more types of hierarchical information may be used.

The types of equipment and the contents of information described below are examples for explanation, and may be changed as appropriate in accordance with the specifications of the equipment monitoring system. In the following, the same elements are denoted by the same reference numerals throughout the drawings, and redundant description thereof will be omitted.

Fig. 1 is a block diagram showing the structure of an equipment instrument monitoring system 10. The plant instrument monitoring system 10 is a system as follows: the state of a plurality of equipment 14 in a facility 12 to be monitored is monitored collectively, and when an abnormality of any equipment is detected, the abnormality is notified to a maintenance worker promptly and accurately, and a trouble coping work is performed to recover the trouble state.

The equipment monitoring system 10 includes

local controllers

26a, 26b provided on the facility 12 side,

worker terminals

30a, 30b on the maintenance worker side, and a central monitoring center 40. The central monitoring center 40 includes a monitoring terminal 42, a management server 44, a failure database 46, a mail server 50, and a network device 54. Each device in the central monitoring center 40 is connected by a LAN (Local Area Network) or the like. The network device 54 of the central monitoring center 40 is connected to the

local controllers

26a, 26b via a public network 28 such as the internet.

The facility 12 is an area or a space where the equipment 14 to be monitored is disposed, and is, for example, a factory, a store, a house, or the like. Hereinafter, a 1-building 6-story building integrated store will be described as the facility 12, but this is an example for explanation.

The equipment 14 is a monitoring target installed in the facility 12. In fig. 1, as an example of the equipment instrument 14, a water supply and drainage apparatus 16 shown as W, a lighting apparatus 18 shown as L, a preventive/disaster prevention apparatus 20 shown as a, a distribution substation apparatus 22 shown as P, and other apparatuses 24 shown as M are illustrated. These are examples, and may include elevators, escalators, air conditioners, and the like.

The

local controllers

26a, 26b shown as LC1, LC2 are local monitoring devices that monitor the status of a plurality of equipment instruments 14 within the facility 12, and when any of these equipment instruments 14 fails, determine a failure ID (identifier) that is previously assigned to each equipment instrument 14. In fig. 1, two

local controllers

26a and 26b are shown, but depending on the scale of the facility 12, 1 local controller may be provided, and in the case of a large-scale facility such as a 6-story building integrated store described as an example, the local controllers may be arranged for each story. Further, in the case where the equipment instruments 14 are provided in addition to the respective floors, on a roof deck, outdoors, or the like, it is preferable to configure a local controller for monitoring them.

The determined fault ID is transmitted to network device 54 of central monitoring center 40 via public network 28 and from network device 54 to devices within central monitoring center 40. The contents of the failure ID and the like will be described later using fig. 2.

In the case where there are a plurality of

local controllers

26a, 26b, the central monitoring center 40 collectively monitors the states of a plurality of equipment instruments 14 to be monitored collectively using them. The central monitoring center 40 collectively gives instructions and the like to a plurality of maintenance workers who perform failure recovery, maintenance, and the like of the equipment 14. The central monitoring center 40 is provided at a place which is separate from the place of the facility 12 and is convenient for maintenance equipment, maintenance workers, and the like. In some cases, a central monitoring center 40 may be provided in the facility 12.

The monitoring terminal 42 is a terminal device that allows a monitoring person to input, output, and read data to, for example, the failure database 46. The monitoring terminal 42 is constituted by a personal computer or the like.

The management server 44, shown as a MS, is a central control device connected to the

local controllers

26a, 26b, the fault database 46, the mail server 50 via the network equipment 54. The management server 44 receives the failure ID transmitted from the

local controllers

26a and 26b, searches the failure database 46, and acquires the failure content name and the location information of the failed equipment 14. Then, the contents are notified to the

respective operator terminals

30a and 30b via the mail server 50, and responses from the

respective operator terminals

30a and 30b are received, so that the trouble-handling work and the like are collectively managed. Next, the flow of information between the elements around the management server 44 will be described with reference to fig. 3.

The failure database 46 shown as DB is a storage device that stores a failure data file 48, and the failure data file 48 is obtained by associating data relating to a failure with a failure ID. The failure data file 48 is a data file in which the failure content name and the arrangement position information of the equipment 14 are associated with the failure ID.

Fig. 2 shows the contents of the fault data file 48. The fault data file 48 is configured to contain a fault data table 60, and wide-area image data 62 and detailed image data 64 relating to the location where the equipment 14 is disposed.

The fault data table 60 shown in fig. 2 (a) is a lookup table in which the relationships between the fault ID, the fault content name, and the arrangement position information of the equipment 14 are summarized into a list. The failure ID is an 8-digit number string, which facilitates data transmission, but when only the number string is viewed, the contents of the failure and the device 14 in which the failure occurred cannot be read.

The failure content name is a name indicating the content of a failure corresponding to the failure ID. The fault content name indicates the fault content and the faulty equipment 14 in brief by a few characters. In the example of fig. 2 (a), the "L-1A failure" is shown as the failure content name corresponding to the failure ID of 00001101. As described with reference to fig. 1, "L" of "L-1A failure" indicates the lighting device 18. "1" of "1A" represents "1 floor" of 1 building in facility 12. "a" is an identification symbol indicating the arrangement position in "1 layer". If the marking method of the failure content name is known, "it is a failure of the lighting devices 18 in 1 floor of the building 1 within the facility 12". However, in the lighting devices 18 of the "1 layer" plurality, it is not known where the lighting device 18 having generated the failure is located.

The fault data table 60 corresponds to 4 pieces of information on the arrangement position of the faulty equipment 14 in association with the fault ID. Two of which are wide area configuration location information. The wide area arrangement position information is information of the wide area image data 62 and the wide area arrangement place. In fig. 2, when the failure ID is 00001101, the wide area image data 62 is 1001.JPG, and the wide area location is "1 floor 1".

Fig. 2 (b) shows wide-area image data 62 for the entire facility 12 as a 6-story building integrated store. The wide area image data 62 of the entire facility 12 is composed of image data representing the arrangement state of each floor, such as image data 1001.JPG representing the arrangement state of 1 floor, image data 1002.JPG representing the arrangement state of 2 floors, image data 1003.JPG representing the arrangement state of 3 floors, and image data 1004.JPG representing the arrangement state of 4 floors, and image data 1007.JPG representing the arrangement state of the roof deck. The wide area image data 62 corresponding to the failure ID 00001101 is 1001.JPG, and is image data indicating the arrangement status of "1 lot 1 floor" as a wide area arrangement location.

Returning to fig. 2 (a), the remaining two of the 4 pieces of information relating to the configuration position of the equipment instrument 14 associated with the failure ID are detailed configuration position information. The detailed placement position information is information of the detailed image data 64 and the detailed placement location. In fig. 2, when the failure ID is 00001101, the detailed image data 64 is 1001001.JPG, and the detailed placement location is "tenant X side".

Fig. 2 (c) is detailed image data 64 showing the arrangement state of each lighting device 18 in "1 floor" of the facility 12 as the 6-floor building integrated store. The detailed image data 64 indicates where the respective illumination apparatuses 18 in the "1 layer" are arranged in 1001.JPG, which is wide area image data on the "1 layer". The location of the lighting device 18 whose failure content name corresponds to the "L-1A failure" is a location blacked out in 1001001.JPG as detailed image data, and this location is a detailed location "tenant X side". Similarly, the location of the lighting device 18 where the failure content name corresponds to the "L-1B failure" is a location blacked out in 1001002.JPG, which is detailed image data. The location of the lighting device 18 where the failure content name corresponds to the "L-1C failure" is a location blacked out in 1001003.JPG, which is detailed image data.

Although not shown in fig. 2 (c), detailed image data 64 indicating the arrangement state of each lighting device 18 in "2 floors" of the facility 12, which is an integrated store having a 6-floor building, is also stored. When the failure ID is 00001102, the failure content name is "L-2A failure", the wide area image data 62 is 1002.JPG, and the wide area configuration site is "1 span 2 layers". The detailed image data 64 at this time is detailed image data indicating the arrangement state of each lighting device 18 in the "2-tier" of the facility 12.

In this way, the failure data file 48 of the failure database 46 is configured to include the failure data table 60, the wide area image data 62, and the detailed image data 64.

Returning again to fig. 1, mail is transmitted and received between the mail server 50 shown as mS and the

operator terminals

30a and 30 b. The communication device 52 is a transmitting/receiving device that performs wireless communication between the mail server 50 and each of the

operator terminals

30a and 30 b. The

worker terminals

30a and 30b on the opposite side of the mail transmission/reception are worker terminals registered in advance. The registration is performed by the management server 44.

The ID of the registered operator terminal to which the mail should be transmitted and the content to be transmitted are transmitted from the management server 44 to the mail server 50. In the transmission of the mail by the mail server 50, the mail content transmitted from the management server 44 is transmitted to the registered

operator terminals

30a, 30b via the communication device 52.

When the mail server 50 receives mails from the registered

operator terminals

30a and 30b via the communication device 52, the received mail contents are transmitted to the management server 44 together with the IDs of the transmitted operator terminals.

Fig. 3 is a diagram showing the processes performed in the elements in time series in association with the process of the management server 44 in the plant monitoring system 10 having the above-described configuration. In fig. 3, the elements are arranged along the horizontal axis, and the information flow is shown by a wavy arrow with the vertical axis as time passes.

Local controllers

26a and 26b, a management server 44, a mail server 50, and

worker terminals

30a and 30b are arranged as the respective elements.

As an example, the following will be described: among the plurality of equipment instruments 14 of the facility 12 of the equipment instrument monitoring system 10, a failure occurs in the lighting equipment 18 disposed on the side of the tenant X of "level 1" which is the monitoring range of the local controller 26 a. Which is an example used to illustrate figure 3.

When the local controller 26a detects an abnormality of the lighting apparatus 18 as the apparatus instrument 14 (S10), the local controller 26a determines a failure ID assigned in advance to the lighting apparatus 18 in which the abnormality is detected, and outputs the determined failure ID to the management server 44 (S12). Here, since the lighting device 18 disposed on the tenant X side of "level 1" has a failure, the output failure ID is 00001101.

The management server 44 receives the failure ID 00001101 from the local controller 26a (S14). Then, based on the received failure ID of 00001101, the failure data file 48 of the failure database 46 is searched (S16), and the failure data is acquired (S18). The failure data is the failure content name and the configuration location information of the equipment instrument. The information on the arrangement position of the equipment includes wide-area image data, a wide-area arrangement location, detailed image data, and a detailed arrangement location.

As described in fig. 2, the failure content name corresponding to the failure ID 00001101 is "L-1A failure", the wide area image data is "1001. JPG", the wide area arrangement location is "1 tenant 1 tier", the detailed image data is "1001001. JPG", and the detailed arrangement location is "tenant X side".

The management server 44 transmits the acquired failure content name and the information on the arrangement position of the equipment to the mail server 50, and the mail server 50 simultaneously transmits the content to the

operator terminals

30a and 30b of all the registered operators (S20). Each maintenance worker receives the mail through each of the

worker terminals

30a and 30b, and confirms the contents of the trouble and the location of the arrangement (S22).

Fig. 4 (a) shows a display screen of mail contents received by the

operator terminals

30a and 30 b. The display screens of the

operator terminals

30a and 30b are the same. On the display screen, a title of "device trouble", "20150520" as a date when trouble occurred, and "15: 00 ", L-1A total failure as the failure content name, and 4 pieces of information as the configuration position information of the equipment.

The arrangement position information of the equipment is 4 pieces of "1 st floor" as a wide area arrangement place, "1001. JPG" as wide area image data, "tenant X side" as a detailed arrangement place, and "1001001. JPG" as detailed image data. For the display of "1001. JPG", which is wide-area image data, the corresponding image data may be highlighted or the like in the entire arrangement state of 1 layer. In "1001001. JPG" as the detailed image data, "tenant X side" may be blackened or the like as described in fig. 2 (c).

Each maintenance worker can specifically grasp the contents of the trouble and the location where the lighting device 18 should be disposed in response to the trouble by looking at the display screen of each

worker terminal

30a, 30 b. Based on the grasped condition, whether the fault can be coped with by going to the fault site is judged. For example, when the maintenance worker who carries the worker terminal 30a determines that the trouble coping work can be dealt with, the maintenance worker clicks a frame "return with current position" displayed on the lower side of the display screen of fig. 4 (a).

Fig. 4 (b) is a reply contact display screen displayed on the operator terminal 30a by clicking the "reply with current position". Here, the title of "contact by device trouble responder", the date and time of trouble occurrence, and the trouble content name are displayed, and a column of "current position xxxxxx", which is the current position of the write responder, is also displayed.

Returning to fig. 3, the user who carries the operator terminal 30a and who has determined that the user can handle the trouble-handling work returns the current position of the user after writing the current position in the column of "current position xxxxxx" (S24). The mail server 50 receives the mail from the responder (S26) and transmits it to the management server 44. The management server 44 acquires the response to trouble from the operator terminal 30a, confirms the current position of the responder (S28), and registers the worker information for trouble handling.

Subsequently, the management server 44 outputs the registered worker information to be handled (S30) and transmits the same to the mail server 50, and the mail server 50 simultaneously transmits the worker information to be handled to all the

worker terminals

30a and 30b of the registered workers (S32).

Fig. 4 (c) is a display screen of each of the

operator terminals

30a and 30b that has received the trouble handling operator information. Here, the title of "equipment trouble responder contact", the date and time when the trouble occurred, the trouble content name are displayed, and "shantian taro work coping reservation" and "current position xxxxxx" are also displayed as trouble responder information. Thus, each maintenance worker can confirm the worker to be handled (S34), and the worker to be handled information can be shared.

When a maintenance operator other than the "shantian taro" registered as the trouble handling operator confirms the screen of (c) in fig. 4 and determines that it is preferable to perform the trouble handling support by himself/herself, a "trouble handling support reply" indicating that fact is transmitted from the operator terminal 30b of himself/herself. The mail server 50 receives the reply and transmits it to the management server 44, and the management server 44 registers the support operator information based on the transmitted "reply to the failure handling supporter". The registered support operator information is transmitted to the

operator terminals

30a and 30b simultaneously via the mail server 50 again. Thus, the "shantian taro" can know that other maintenance workers are driving to the support, and can share the support worker information.

For comparison, fig. 5 shows a display screen of the worker terminal 31 that receives a mail generated by a failure in the related art. In the related art, only the title of "device failure", failure generation date and time information, and failure content name are transmitted. Since the configuration information of the equipment 14 having a failure is not transmitted, the maintenance worker who has received the mail needs to access the monitoring terminal 42 of the central monitoring center 40 in order to know the detailed information, and cannot perform the trouble-handling work quickly and cannot share the information of the trouble-handling worker.
