Details of the exclusive flag will be described later. Usually, only one map data table 25 is provided.

The system data table 26 is provided as system data storage means and stores a unique index number for each system data for each system included in the entire map. In each system data, at least pointer information to each facility data included in the system, pointer information to map data to which the system belongs, pointer information to other system data in the same map, and an exclusive flag are set at least. Is done. In the exclusion flag, when equipment on the corresponding system is subject to construction and exclusive control is performed at the system level, that fact is set at that time, but other information such as pointer information is set in advance. System data table 26
Usually, only one is provided.

Here, the exclusive flag will be described. In the present embodiment, the exclusive control unit is a map, a system, and a facility.
The feature is that the exclusion range for performing the exclusion control on the hierarchy level, that is, the facility, is set to three levels. The exclusion flag is flag information for indicating the exclusion control unit. Therefore, if the exclusion target range is a map unit, the exclusion flag of the corresponding map data in the map data table 25 is set to “ON”, and the exclusion flag of the corresponding system data in the system data table 26 is set to “OFF”.
On the other hand, if the exclusion target range is a system unit, the exclusion flag of the corresponding system data in the system data table 26 is set to “O”.
N ", and the exclusive flag of the corresponding map data in the map data table 25 is set to" OFF ".

The equipment data table 27 is provided as equipment data storage means, and stores a unique index number for each piece of equipment data for each equipment included in the entire map. Each piece of equipment data contains pointer information to the map data to which the equipment belongs, pointer information to the system data to which the equipment belongs, pointer information to other equipment data in the same system, At least an execution type as identification information and an exclusion type indicating a hierarchy level when exclusive control of the facility is performed are set. The construction work number and the exclusion type are set at the time of construction and cleared when the construction is completed. At this time, the construction number is set to the construction number for which the equipment is to be constructed, and the exclusion type is set to the hierarchical level that is the unit of exclusive control, that is, one of “map”, “system”, and “equipment”. Is done.

In the present embodiment, the data tables 24 to 27 have the data structure in which the system data and the equipment data have pointer information and the data is chained from the head data. Each system data and each facility data may be directly related. For these data structures,
This is a design matter.

A feature of the present embodiment is that a range to be excluded is hierarchically provided with a map, a system, and a facility. Is to go through the stages. In other words, the exclusion target area, which was initially the entire map (section) in a certain construction, is disassembled when another construction request is made within the same map, and reconstructed into a range that can be gradually combined with the system and equipment. With this configuration, it is possible to accept a later construction request while maintaining exclusion, and to perform detailed exclusive control when another construction request occurs, without using unnecessary exclusive control processing. I'm done.

Next, the exclusive control process according to this embodiment will be described with reference to the flowchart shown in FIG. Here, when the construction is not performed in the map A shown in FIG.
2 A21 and A22 are rehabilitated (hereinafter referred to as “construction A”), followed by facilities A13 of system A1 in map A.
Renovation work (hereinafter referred to as “Construction B”)
Will be described by taking as an example a case where processing ends first.

At the client terminal 10, a construction request is made to the server 20 by designating a range to be constructed on the display screen.

In the server 20, the construction management unit 21
When a construction request is received from the client terminal 10 (step 101), it is confirmed that the request is a construction request (step 102). Then, the exclusion type of the equipment requested for the construction request is confirmed (step 103). The equipment data of the equipment targeted for the construction, in this example, the setting contents of the exclusion type of each equipment data of the equipments A11, A21, A22 are acquired. If nothing is set, it means that it is not subject to other construction. In this example, since the construction A is the first construction request in the map A, nothing is set in the equipment data, but any of the equipment data includes “map”, “system”,
If any of the “equipment” is set, the corresponding equipment has already been the subject of another construction, so that the construction cannot be performed. Therefore, in such a case, the fact is returned to the client terminal 10 (steps 104 and 10).
5).

When the construction management unit 21 determines that construction is possible (step 104), it generates a construction management data table 24 relating to the construction (step 106). The construction management data table 24 includes the facilities A11, which are the construction targets identified based on the construction request from the client terminal 10,
A21, A22 pointer information, unique construction number assigned to the construction request (in this example, "KM-S246-02
A ”).

Next, the exclusive control processing unit 22 performs setting processing of various data tables 25 to 27 and setting of exclusive information such as generation of an exclusive key of the construction management data table 24 in order to perform exclusive control (step 107). . Details of this processing will be described with reference to the flowchart shown in FIG.

Target equipment A of construction management data table 24
Equipment A in the equipment data table 27 linked from 11
11 based on the data 27-1
25-1 of map A in the map and system data table 2
Reference is made to the state of the exclusion flag set in each of the data 26-1 of the system A1 in Step 6 (Step 201,
02). Since the construction A is the first construction in the map A, both exclusive flags are “OFF”. Therefore, it can be determined that the exclusion target range in the construction A can be generated using the "map A", which is the widest area, as the exclusion key. In this case, the exclusive flag of the data 25-1 of the map A is set to "ON" (step 203). In addition, the exclusion type of each facility in the facility data table 27 including the other facilities A21 and A22 is set to “map”, and the construction work number is the construction number of the construction A (“KM-S246-02A” in this example). (Step 204). Then, "map A" is registered as an exclusive key of the construction management data table 24 (step 205). FIG. 7 is a diagram showing the transition of the exclusion target range and the exclusion key. As shown in the left diagram of FIG.
In the construction A, the entire map A is set as the exclusion target range. FIG. 8 shows a schematic diagram of the exclusive relationship between the systems and facilities included in Map A at this time.

Next, an operation when the server 20 receives a request for repair work for the work B in this state, that is, for the equipment A13 of the system A1 in the map A, will be described.

In FIG. 5, the construction management unit 2 of the server 20
When confirming that the request is for construction B from the client terminal 10 (steps 101 and 102), 1 checks the exclusion type of the target facility (facility A13) in construction B (step 103). In this example, since nothing has been set yet for the exclusion type of the facility A13, it is determined that construction is possible, and the construction management data table 24 for construction B is generated (step 106). In the construction management data table 24, pointer information of the facility A13 to be constructed identified based on the construction request from the client terminal 10 and a unique construction number assigned to the construction request are set.

Subsequently, the exclusive control processing unit 22 sets various data tables 25 to 27 and generates an exclusive key of the construction management table 24 in order to perform exclusive control (step 107). First, the map data table 25 based on the data of the equipment A13 in the equipment data table 27 linked from the target equipment A13 of the construction management data table 24.
25-1 of map A in the map and system data table 2
Reference is made to the state of the exclusion flag set in each of the data 26-1 of the system A1 in No. 6. As a result of the exclusion control process for the construction A, the exclusion flag of the map A is “ON” and the exclusion flag of the system A1 is “OFF”. The exclusive key of the previous construction A is registered in "map A", but the facility A1
It has been confirmed that the exclusion type of No. 3 has not been set and that the construction is possible. Therefore, the hierarchy level of the exclusion control of the construction A is set to a lower level, that is, the system or the facility is reset, so that the construction B is also in the same period as the construction A. It can be seen that exclusive control can be performed. Therefore, it is necessary to reconfigure the setting contents of the exclusive control for the construction A. This resetting is performed as follows.

First, the construction of the exclusive key "map A" for which the construction area is the same as the construction B, and the exclusion type is "map"
The equipment A11, A21, and A22 are referred to by referring to the data of each equipment in the equipment data table 27.
Can be specified (step 211). Next, the facilities A11, A21, and A22 and the facility A1 in the construction B
Then, it is compared whether the three systems do not overlap (step 21).
2). The system to which each facility belongs can be obtained from the belonging system data of the data of each facility. Here, equipment A1
1 and equipment A13 have the same system.
"Equipment A11" is registered as the exclusive key (step 213). At this time, the original “Map A” is deleted. Further, the exclusion type of the data of the facility A11 is updated from "map" to "facility" (step 214).

On the other hand, since the systems of the facilities A21 and A22 and the facility A13 do not overlap, "system A2" is further registered as an exclusive key of the construction A (step 218). Then, the exclusion type of the data of the facilities A21 and A22 is updated from "map" to "system" (step 219). Further, the exclusive flag of the data of the map A in the map data table 25 is updated to “OFF”, and the exclusive flag of the data of the system A2 in the system data table 26 is updated to “ON” (steps 220 and 221). It should be noted that, in the flowchart, the processing for updating the exclusive flag of the data of the map A in the map data table 25 to “OFF” is illustrated as another processing depending on whether or not the system of the equipment is overlapping. Although indicated by reference numeral 220, when both processes are performed as in the present embodiment, the exclusion flag may be updated in either of the processes.

After the setting contents of the exclusive control of the construction A are reconfigured as described above, the exclusive control of the construction B is set. First, the exclusion type of the data of the facility A13 is
When the map, the system, and the equipment are considered in stages, the equipment is changed to “equipment” from the existence of the equipment A11 under construction (step 21).
6). Also, “equipment A13” is registered as an exclusive key of construction B (step 217). If the exclusion type of the construction B is the system, the steps 222 and 2
23, but as in the present embodiment,
If the exclusion type is performed at the same time as the processing for equipment, the processing is not performed. FIG. 6 is a flowchart schematically illustrating each setting process of exclusive information according to the present embodiment.
To 205, steps 213 to 217, step 218 to
233, steps 241 to 245) do not necessarily have to be processed in this order. The state of the exclusion target range and the exclusion key after the above exclusion control processing is shown in the center of FIG. FIG. 9 shows a schematic diagram of the exclusive relationship between the systems and facilities included in the map A at this time.

As described above, according to the present embodiment, a plurality of works are performed simultaneously and in parallel in the case of work on other facilities even within the same map or even within the same system. be able to. Exclusive control is not always performed for each unit of equipment, but it is verified whether or not it can be excluded step by step with maps, systems, and equipment. There is no need to perform control processing. For this reason, unnecessary exclusive control processing need not be performed, and the system load can be reduced.

Next, the server 20 is connected to the client terminal 10.
Exclusive control processing when a notice of the end of the construction B is received from will be described.

When the construction management unit 21 of the server 20 receives the completion notice of the construction from the client terminal 10 (steps 101 and 102), the exclusive information relating to the construction B is released and the exclusive information relating to the construction A is reconfigured. The information is reconfigured (step 108). The details of this process will be described with reference to the flowchart shown in FIG.

First, the exclusion control management unit 22 clears the exclusion type of the data of the facility A13 which is the target facility of the construction B. Specifically, the exclusion type set as “equipment” is updated with the initial value “none”. Also, the construction work number in the data of the facility A13 is cleared (step 301).

Here, when the exclusion type before updating the data of the facility A13 is "system", the exclusion flag of the data of the system A1 in the system data table 26 is set to "OFF" (steps 302, 303, 304). Further, the construction management data table 24 for construction B is deleted (step 306). As a result, the exclusive key is also deleted. When the exclusion type is “map”, the exclusion flag of the map A data in the map data table 25 is set to “OFF”.
(Step 305), the construction management data table 24 for construction B is deleted (step 306). Also,
When the exclusion type is “equipment” as in the above example,
Since the exclusive flags of the data of the system A1 in the system data table 26 and the data of the map A in the map data table 25 are both "OFF", the construction management data table 24 relating to the construction B is simply deleted here (step). 306).

After the deletion of the exclusion information on the construction B is completed, it is necessary to reconfigure the exclusion information on the exclusion construction A (step 307). This can be reconfigured by performing the exclusive information setting process based on FIG. 6 described above. In this example, the exclusive flag of the data 25-1 of the map A in the map data table 25 and the exclusive flag of the data 26-1 of the system A1 in the system data table 26 are both "OFF". The exclusive information of the construction A is set in the same manner as in the case of the setting. The detailed description of this setting process is the same as that described above, and will not be repeated. The state of the exclusion target range and the exclusion key after this processing is shown in the right diagram of FIG. 7. As is clear from FIG. 7, the state returns to the same state as before the request for the construction B. The exclusive relationship between the systems and facilities included in Map A at this time is shown in FIG.
Will be the same as

Finally, the server 20 is connected to the client terminal 1
The processing when the completion notification of the construction A is received from 0 is basically the same as the processing of the construction B. However, in the processing shown in FIG. 10, since the exclusion type of the data of each of the facilities A11, A21, and A22 is "map", the exclusion type is set to "none", and the data of each of the facilities A11, A21, and A22 is processed. By clearing the construction number and deleting the construction management data table 24 for the construction A, the exclusive key is deleted.

As described above, according to the present embodiment, exclusive control can be performed for each facility, so that different facilities on the same system in the same map may be different simultaneously and in parallel. You can do the construction.

[0045]

According to the present invention, the exclusive control unit is hierarchized and the exclusion-exclusive hierarchical level is determined by verifying from the upper level, so that unnecessary exclusive control processing is not required. In other words, if the hierarchy level is drawing, system, and equipment, and if there is no equipment that is exclusively controlled by another construction in the same drawing, the construction is excluded at the map level, and If there is no facility that is exclusively controlled by other works on the same system, the work is excluded at the system level, and even if it is on the same system in the same drawing, When exclusive control is not performed by construction, exclusion is performed at the facility level for the construction. As described above, exclusive control is initially performed in a rough range, and detailed exclusive control processing is performed when a construction request is made from the other construction to the same map and the same system. Can perform exclusive control on a facility basis. In addition, since exclusive control processing can be performed at a required level, unnecessary detailed exclusive control processing is not required, so that the system load can be reduced.

Further, even if facilities not subject to construction, such as a map or a system, are included in the scope of exclusive control in the preceding construction, the hierarchical level is gradually lowered to finally achieve exclusive control in units of facilities. Can be set, so that exclusive control of later construction can be accepted.
