[Operation of First Embodiment]
Next, operations of the device management system 1 and the device management apparatus 10 according to the present embodiment will be described with reference to FIG. FIG. 2 is a sequence diagram illustrating a target device specifying operation according to the first embodiment.

  Here, a case where three devices 20A, 20B, and 20C are connected to the device management apparatus 10 via the communication line L will be described as an example. These devices 20A, 20B, and 20C have the same configuration as the device 20 shown in FIG. Further, here, a case where the conditions used for the inquiry include a condition for specifying the content of the abnormality history included in the abnormality history information indicating the abnormality detected by the device 20 among the device information stored in the device 20. This will be described as an example.

  First, the device inquiry unit 16 of the device management apparatus 10 acquires a condition input from the operation input unit 12 by an operator (step 100), and is a target device having target history information (target information) that matches the condition. An inquiry message for inquiring whether or not there is is transmitted from the communication I / F unit 11 to each of the devices 20A, 20B, and 20C via the communication line L (step 101). At this time, the inquiry message is transmitted to each of the devices 20A, 20B, and 20C in parallel by multicast.

In response to the inquiry message, the inquiry response unit 26 of the devices 20A, 20B, and 20C retrieves target history information that matches the condition specified in the inquiry message from the abnormality history information stored in its own storage unit 25. (Step 102).
In this example, it is assumed that the target history information exists in the devices 20A and 20B and the target history information does not exist in the device 20C (step 103).

  Thus, the devices 20A and 20B in which the target history information exists, that is, the inquiry response unit 26 of the target device, sends a response message including its own address preset in the storage unit 25 to the communication I / F unit 22 and the communication A reply is sent to the device management apparatus 10 via the line L (steps 104 and 105). A response message is not returned from the device 20C for which no target history information exists.

In response to the response message from the devices 20A and 20B received by the communication I / F unit 11, the target device specifying unit 17 of the device management apparatus 10 specifies the devices 20A and 20B that transmitted the response message as target devices ( Step 106), identification information such as a device name indicating these target devices is displayed on the screen display unit 13 (step 107).
As a result, a target device that matches the input condition is identified from each device 20 and displayed on the screen display unit 13.

  Thereafter, when the operation input unit 12 detects a collection instruction operation for instructing collection of device information from the target device (step 110), the device information collection unit 18 of the device management apparatus 10 is identified as the target device. From the devices 20A and 20B, part or all of the device information stored in the devices 20A and 20B is sequentially collected via the communication line L.

  First, the device information collection unit 18 sends an information request message for requesting abnormality history information related to the abnormality history specified by the collection instruction operation from the communication I / F unit 11 via the communication line L as device information used for management control. To the device 20A (step 111).

  In response to the information request message from the device management apparatus 10 received by the communication I / F unit 22, the device information transmission unit 27 of the device 20 </ b> A specifies the specified abnormality history from the abnormality history information stored in the storage unit 25. The abnormality history information on the information is acquired and transmitted to the device management apparatus 10 via the communication I / F unit 22 and the communication line L by an information response message (step 112).

  In response to the information response message from the device 20A received by the communication I / F unit 11, the device information collection unit 18 extracts the abnormality history information of the device 20A from the information response message and stores it in the storage unit 14 (step S1). 113).

  Subsequently, the device information collection unit 18 sends an information request message for requesting abnormality history information related to the abnormality history designated by the collection instruction operation from the communication I / F unit 11 to the communication line L as device information used for management control. To the device 20B (step 114).

  In response to the information request message from the device management apparatus 10 received by the communication I / F unit 22, the device information transmission unit 27 of the device 20 </ b> B uses the specified abnormality history from the abnormality history information stored in the storage unit 25. Is acquired and transmitted to the device management apparatus 10 via the communication I / F unit 22 and the communication line L by an information response message (step 115).

  In response to the information response message from the device 20B received by the communication I / F unit 11, the device information collection unit 18 extracts the abnormality history information of the device 20B from the information response message and stores it in the storage unit 14 (step S1). 116).

After collecting the abnormality history information from each of the devices 20A and 20B in this way, the device information collecting unit 18 is stored in the storage unit 14 in accordance with the confirmation operation input from the operation input unit 12 by the operator. The abnormal history information of each of the devices 20A and 20B is displayed on the screen display unit 13 (step 117).
Thereby, the part designated by the collection instruction operation in the abnormality history information stored in each device 20 is collected from each device 20 and presented to the operator.

Next, with reference to FIG. 3, the conditions used for specifying the target device will be described. FIG. 3 is a condition example for specifying the target device according to the first embodiment.
First, in the setting example of FIG. 3A, “2014/02/14 or later” is set as a condition regarding “occurrence date and time” indicating the date and time when an abnormality has occurred among items registered in the abnormality history information. “Error B is set as a condition relating to the“ error type ”indicating the type of the error that has occurred. According to this setting example, an error that occurred in“ 2014/02/14 or later ”and“ error ” Abnormal history information relating to an abnormality of the error type “B” is specified as the target history information.

  Next, in the setting example of FIG. 3B, among the items registered in the abnormality history information, “2014 / “02/14 or later” is set, and “error B is set as a condition relating to“ error type ”indicating the type of the abnormality that has occurred. With this setting example,“ 2014/02/14 or later ”is finally generated. Abnormality history information relating to an abnormality of the date and time and an error type “Error B” is specified as the target history information.

  Next, in the setting example of FIG. 3C, “this month” is set as the condition regarding “occurrence month” indicating the year and month when the abnormality occurred among the items registered in the abnormality history information. “Error B” is set as a condition regarding the “error type” indicating the type of abnormality that has occurred. According to this setting example, the abnormality history information related to the abnormality of “error B” and the abnormality type having the last occurrence date and time “current month” is specified as the target history information.

  FIG. 4 is an explanatory diagram showing an abnormality history management state in the device. When the abnormality history information indicating the abnormality detected by the control monitoring unit 23 of the device 20 is recorded in the storage unit 25, the presence / absence of the error type of the abnormality may be managed for each month. The occurrence of these errors is initialized at the beginning of the next month. In the example of FIG. 4, error A has occurred in the middle of last month, and errors B and C have not occurred. It can also be seen that error B has already occurred in the period up to the current position of this month. If the presence / absence of such an error is managed by each device 20, it is possible to respond immediately when an inquiry is made under the conditions of FIG. 3C, and it is not necessary to search all abnormality histories.

[Effect of the first embodiment]
As described above, according to the present embodiment, in the device management apparatus 10, the device inquiry unit 16 determines whether each device 20 is a target device that includes target information that matches the input condition in its own device information. The inquiry and target device specifying unit 17 specifies and displays the device 20 that has returned a response indicating that it has target information in response to the inquiry as the target device that is subject to management control corresponding to the condition. It is what I did.

  As a result, if the condition related to the device information related to the abnormality to be investigated is input as the condition, the target device having the device information to be confirmed by the worker is identified, and the device information data to be confirmed by the worker The amount is reduced. Therefore, when checking the device information stored in each device 20, it is possible to reduce the burden on the worker and improve the work efficiency.

  For example, when dealing with an abnormality that has occurred, if a condition for specifying the contents of the abnormality history related to the abnormality is input, the target device having the abnormality history information to be confirmed by the operator can be identified very easily. . Therefore, out of all the abnormality history information stored in each device 20, only the abnormality history information is collected from these target devices, and the abnormality history information necessary for maintenance can be presented to the operator accurately and easily. Can do. For this reason, it is possible to easily and significantly reduce the amount of abnormality history information required for determining whether or not the maintenance is required for the device 20 or the equipment, and to improve the work efficiency required for checking the abnormality history information. .

  Further, in the present embodiment, the device inquiry unit 16 distributes an inquiry message for inquiring whether or not there is target information that matches the condition to the devices 20 in a multicast manner at the time of inquiry, and the inquiry response of each device 20 When the target information exists in its own device information, the unit 26 returns the address of the device 20 as a response, and the device information collection unit 18 returns the address of the device 20 as a response among the devices 20 20 may be specified as the target device, and device information may be requested from the target device based on the addresses of the target devices.

Thereby, the device management apparatus 10 can easily acquire the address of the target device having the target information, and the address of each device 20 connected to the communication line L is not set in the device management apparatus 10 in advance. It is also possible to collect device information.
In addition, since the multicast method is used, the inquiry message can be distributed to each device 20 in a lump even when addresses are given discontinuously to each device 20.

In general, in a facility management system that monitors and controls equipment installed in various locations such as buildings and plants, equipment (controllers) is installed in accordance with the scale and configuration of the facility. There are many cases where it is installed. In some cases, each device 20 is managed by being divided into sub-networks using different communication lines L, and the number of devices 20 connected may be different for each subnet.
Therefore, since the configuration of the device 20 connected to the communication line L may change due to addition / deletion / address change of the device 20, all the devices connected to the communication line L in the device management apparatus 10. Address management work for managing the 20 latest addresses is a heavy burden on the operator.

  According to the present embodiment, among the devices 20 connected to the communication line L, since the device management apparatus 10 can automatically grasp the address of the target device having the target information, the address management work is not required. It is possible to reduce the burden on the worker, and it is possible to reliably avoid omission of collection of target information due to an address setting error, and it is possible to accurately collect and present the target information to be confirmed by the worker. It becomes.

[Second Embodiment]
Next, the device management system 1 and the device management apparatus 10 according to the second embodiment of the present invention will be described with reference to FIG. FIG. 5 is a sequence diagram illustrating a target device specifying operation according to the second embodiment.

  In the first embodiment, the condition used for the inquiry is the condition that specifies the content of the abnormality history included in the abnormality history information indicating the abnormality detected by the device 20 out of the device information stored in the device 20. The case has been described as an example. In the present embodiment, as an example, the condition used for the inquiry is a condition that specifies the setting content included in the setting information used for the processing operation in the device 20 among the device information stored in the device 20. explain.

When applying changes to the setting information registered in each device 20 for specifying the processing operation of the device 20, it is necessary to check the setting contents. It will be specified by. For this reason, if an operator knows which device 20 has such setting information, the device 20 to which the change or correction of the setting information is to be applied can be easily specified.
For this reason, in the present embodiment, as shown in FIG. 5, until the target device is identified by the response returned from each device 20 in response to the inquiry from the device management apparatus 10, The configuration is as follows. Other configurations in the present embodiment are the same as those in the first embodiment, and a detailed description thereof is omitted here.

[Operation of Second Embodiment]
Next, operations of the device management system 1 and the device management apparatus 10 according to the present embodiment will be described with reference to FIG.
Here, a case where three devices 20A, 20B, and 20C are connected to the device management apparatus 10 via the communication line L will be described as an example. These devices 20A, 20B, and 20C have the same configuration as the device 20 shown in FIG. Here, a case will be described as an example where the conditions used for the inquiry include conditions for specifying the setting contents included in the setting information used in the device 20 among the device information stored in the device 20.

  First, the device inquiry unit 16 of the device management apparatus 10 acquires a condition input from the operation input unit 12 by an operator (step 200), and is a target device having setting information (target information) that matches the condition. An inquiry message for inquiring whether or not is transmitted from the communication I / F unit 11 to each of the devices 20A, 20B, and 20C via the communication line L (step 201). At this time, the inquiry message is transmitted to each of the devices 20A, 20B, and 20C in parallel by multicast.

In response to the inquiry message, the inquiry response unit 26 of the devices 20A, 20B, and 20C searches the setting information stored in its own storage unit 25 for target setting information that matches the condition specified in the inquiry message. (Step 202).
In this example, it is assumed that the target setting information exists in the devices 20A and 20B, and the target setting information does not exist in the device 20C (step 203).

  Thereby, the devices 20A and 20B in which the target setting information exists, that is, the inquiry response unit 26 of the target device, sends a response message including its own address preset in the storage unit 25 to the communication I / F unit 22 and the communication A reply is sent to the device management apparatus 10 via the line L (steps 204 and 205). Note that a response message is not returned from the device 20C for which target setting information does not exist.

In response to the response message from the devices 20A and 20B received by the communication I / F unit 11, the target device specifying unit 17 of the device management apparatus 10 specifies the devices 20A and 20B that transmitted the response message as target devices ( Step 206), identification information such as a device name indicating these target devices is displayed on the screen display unit 13 (step 207).
As a result, the target device that matches the input condition, that is, the target device having the setting content specified by the condition is identified from each device 20 and displayed on the screen display unit 13.

Next, with reference to FIG. 6, conditions used for specifying the target device will be described. FIG. 6 is a condition example for specifying a target device according to the second embodiment.
First, in the setting example of FIG. 3A, “XXXX” is set as a condition relating to “differential constant” indicating a parameter used in PID control or the like among the setting contents registered in the setting information. With this setting example, the device 20 having the setting information whose setting value related to “differential constant” is “XXXX” is specified.

Therefore, before applying the setting change, if an inquiry is made under the above conditions using the setting value “XXXX” up to that point, the device 20 that is the target of the setting change can be specified.
Also, for example, based on the operator's operation, an instruction is transmitted from the device management apparatus 10 device setting unit 15 to the device information setting unit 24 of the device 20 whose setting is to be changed, and the setting value of the parameter is set to “YYYY”. After making the change, if an inquiry is made under the above conditions using the previous setting value “XXXX”, it is possible to identify the device 20 in which the previous setting value “XXXX” remains set due to a setting change error.

  Next, in the setting example of FIG. 3B, “XXXX” is set as a condition regarding “differential constant” indicating a parameter used in PID control or the like among the setting contents registered in the setting information. “001 to 099” is set as a condition regarding “address range” indicating a range of 20 addresses. With this setting example, the device 20 having the setting information related to the “differential constant” is “XXXX” and the setting information included in the “address range” in which the address of the device 20 is “001 to 099” is specified. .

Generally, in a facility management system for managing a building, as a device (controller) 20 arranged on each floor, an address assignment is made so that the device 20 on the floor can be recognized from the address by assigning an upper digit for each floor. Used.
Therefore, in the case where the device 20 arranged on a specific floor among the devices 20 arranged across a plurality of floors is targeted, the device 20 on the desired floor is used using the condition of “address range”. Should be specified. Note that the condition of “address range” can be similarly applied to the first embodiment.

[Effect of the second embodiment]
