DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing display device for displaying drawing data in a server on a CRT of a workstation.

[0002]

2. Description of the Related Art FIG. 6 is a block diagram showing a conventional drawing display device. In the drawing, reference numeral 1 denotes a host computer which comprises a CPU 1a, a storage device 1b, etc., and corrects equipment data, etc. A storage device 3 for storing drawing data composed of (image data) and equipment data (vector data) reads the drawing data stored in the storage device 2 and receives the corrected equipment data from the host computer 1. A server 4 for updating equipment data in the storage device 2, a LAN 4, and an EWS (workstation) 5 for reading drawing data from the server 3 and displaying the drawing data on a CRT (display device) 6.

Next, the operation will be described. EWS5 C
The drawing data to be displayed at RT6 is managed by the server 3, and when it is necessary to display the drawing data, E
By requesting the drawing data from the WS 5 to the server 3, the drawing data is transmitted from the server 3 to the EWS 5 via the LAN 4, and the EWS 5 converts the drawing data into a CR.
Display at T6.

Here, the drawing data is composed of topographic map data and equipment data. The topographic map data is image data, usually about 130 KB per screen, and the equipment data is vector data. About 50K per
It is about B. Therefore, about 70% of the drawing data is topographic map data. FIG. 7 shows an example of drawing data. In this case, the drawing data is composed of meshes M1 to M15.

When correcting equipment data, an operator or the like corrects equipment data stored in the storage device 1b of the host computer 1 from a terminal of the host computer 1. As a result, the corrected facility data is transmitted from the host computer 1 to the server 3, and the server 3 updates the facility data in the storage device 2 to complete the processing.

[0006]

Since the conventional drawing display device is configured as described above, if the equipment data stored in the storage device of the server is destroyed due to a bug in the program or the like. However, there has been a problem that there is a risk that construction or monitoring of the facility may be performed based on the destroyed facility data.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and when equipment data stored in a storage device of a server is destroyed due to a bug in a program or the like, It is an object of the present invention to provide a drawing display device capable of avoiding construction or monitoring of equipment based on destroyed equipment data.

[0008]

Means for Solving the Problems] FIG <br/> surface display device according to the invention of claim 1, the server compares the facility data equipment data and the host computer in the storage device stores, facilities
If the data does not match, an error list is presented .

Further, drawing display device according to the invention of claim 2, the server compares the facility data equipment data and the host computer in the storage device stores a plurality of times,
If the equipment data does not match, provide an error list
It is obtained as that.

[0010]

According to the first aspect of the present invention, the drawing display device compares the equipment data in the storage device with the equipment data stored in the host computer.
By providing the server that presents the error list, it is possible to recognize the quality of the equipment data .

The drawing display device according to the second aspect of the present invention compares the equipment data in the storage device with the equipment data stored in the host computer in a plurality of times,
If the data does not match, a server that presents an error list is provided to recognize the quality of the equipment data.
Will be able to

【Example】

Embodiment 1 FIG. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram showing a drawing display device according to an embodiment of the present invention. In the drawings, the same reference numerals as those in the related art denote the same or corresponding parts, and a description thereof will be omitted. Reference numeral 7 denotes a server for judging the consistency between the equipment data in the storage device 2 and the equipment data stored in the host computer 1, and reference numerals 8 and 9 denote CRTs and printers for displaying the judgment results of the server 7.

Next, the operation will be described. FIG. 2 is a flowchart showing the operation of the drawing display device of FIG. 1. The operation will be described below with reference to FIG. 2. However, the operation in which the EWS 5 receives the drawing data from the server 7 and displays it on the CRT 6 is a conventional operation. The description is omitted because it is the same as the above.

First, the server 7 sends the host computer 1
Is transmitted to the server 7 (step ST1), the host computer 1 transmits the facility data to the server 7 (step ST2). Thereby, the server 7 temporarily stores the facility data in the temporary file TM of the server 7 (step ST3).
Here, FIG. 3A shows equipment data stored in the temporary file TM.

The server 7 stores the temporary file T
M and the equipment data in the storage device 2 (FIG. 3
(B) is compared in mesh units (step ST).
4, ST5). For example, if it is the mesh M5 of the temporary file TM, it is checked against the mesh M5 of the storage device 2. If there is a mismatch in the equipment data, the mesh number (for example, M3) including the mismatched equipment data is output to the CRT 8 and the printer 9 as an error list (step ST6). This allows the operator to recognize that the equipment data has been destroyed,
Thereafter, construction and monitoring of the equipment based on the destroyed equipment data can be avoided.

Embodiment 2 FIG. In the first embodiment, the case where the server 7 requests the host computer 1 to transmit all the equipment data (meshes M1 to M15) has been described. However, as shown in the flowchart of FIG. If the verification of the equipment data whose quantity is not completed, for example, the verification of the equipment data in the meshes M4 to M15 is not completed, a transmission request for a certain amount of the equipment data (for example, the meshes M4 to M7) may be made. Here, whether or not the collation is not completed is determined by referring to the collation completion flag in FIG. 5B. By doing so, the time spent for determining consistency at one time is shorter than in the first embodiment.

[0017]

As described above, according to the first aspect of the present invention,
If, servers can compare the facility data equipment data and the host computer in the storage device stores, facilities data one
If not, an error list is provided so that the quality of the equipment data can be recognized.
As a result, the equipment data in the storage device
Even if it is destroyed due to the cause, there is an effect that construction and monitoring of the facility based on the destroyed facility data can be avoided.

[0018] According to the second aspect of the invention, servers are, because facilities data and the host computer in the storage device is configured to compare a plurality of times the equipment data stored, according to claim 1 The same effect as that of the first invention can be obtained, and the time required for one comparison process can be shortened.
