Abstract

A plant management system including a terminal device provided in each factory, a server connected to the terminal device through a network, and a data base connected to the server. The server provides, to the terminal device, storage of information to the data base and reading of the information of the data base. Information about each plant of each factory and a history of movement of the plant and a history of maintenance are stored in the data base. It is possible to unitarily manage the location, movement and maintenance histories of the plant. Moreover, it is possible to unitarily manage parts for maintenance of the plant together. Furthermore, it is possible to implement a worldwide plant management at a minimum cost by utilizing the internet and the WWW browser.

Claims

1. A plant management system comprising a terminal device provided in each factory, a server connected to the terminal device through a network, and a data base connected to the server, in which the server provides, to the terminal device, storage of information to the data base and reading of the information of the data base,

wherein information about each plant of each factory and a history of movement of the plant and a history of maintenance are stored in the data base.

2. The plant management system of claim 1, wherein the movement of the plant or the execution of the maintenance is inputted from the terminal device and is stored as the history of the movement or the history of the maintenance in the data base.

3. A plant management system comprising a server connected to a terminal device in each factory through a network and a data base connected to the server,

wherein the server includes plant registering means for storing, in the data base, information about a plant inputted from the terminal device, part registering means for storing, in the data base, information about a part inputted from the terminal device, plant movement managing means for storing, in the data base, information about movement of the plant inputted from the terminal device, maintenance history managing means for storing, in the data base, information about execution of a maintenance work of the plant which is inputted from the terminal device, maintenance planning means for storing, in the data base, a maintenance plan of the plant which is inputted from the terminal device, plant structure registering means for storing a relationship between the plant and a component of the plant which are inputted from the terminal device, part stock managing means for storing, in the data base, information about receipt and discharge of the part inputted from the terminal device, master managing means for changing each master of the data base from the terminal device, term managing means for extracting from the maintenance plan a maintenance plan in which the number of days to an execution date is equal to or less than a predetermined term, mail notifying means for transmitting a guidance mail for maintenance execution to an object plant management department of the extracted maintenance plan, and retrieval reading means for retrieving information in the data base and presenting the information to be readable to the terminal device.

4. The plant management system of claim 3, wherein the term managing means extracts the maintenance plan which has not been executed after the predetermined term passes since the maintenance plan and the mail notifying means transmits a demand mail for the maintenance execution to the object plant management department of the extracted maintenance plan.

5. The plant management system of claim 3, wherein at least any of the plant registering means, the part registering means, the plant movement managing means, the maintenance history managing means, the maintenance planning means, the plant structure registering means and the master managing means has an electronic approving function for acquiring an approval from the terminal device through the network and the information after acquirement of approval is intended for the retrieval reading.

6. The plant management system of claim 3, wherein the plant registering means has a function of outputting a plant number peculiar to a plant as a bar code, and reads the bar code attached to the plant and collates the bar code with the information about the movement of the plant which is stored in the data base, thereby collating actual things of the plant.

7. A plant management system comprising a server connected to the terminal device of each factory through a network and a data base connected to the server,

wherein the data base includes a plant information table storing information about a plant, a plant history table storing a movement history of the plant, a maintenance history table storing a history of maintenance of the plant, a maintenance plan table storing a maintenance plan, a plant structure table storing a relationship between the plant and a plant component, a part information table storing a stock situation of a part in each stockroom, an ordering history table storing an ordering history of a part, and a receipt and discharge history table storing a history for receipt and discharge of the part.
