Abstract

In order to set automatically related software in a facility management system and to start quickly and easily a state monitoring when various measuring instruments are attached to or removed from a facility to be monitored, secured, and maintained, when a sensor which is the measuring instrument is connected, a measuring-instrument reading device which is a lower level device transmits a type of the measuring instrument and a purpose of connecting the measuring instrument to a directory server, the directory server generates an instance by referring to class information and generates and registers a relation instance by referring to an inter-class relationship, the directory server transmits the generated instance to a related devices on the basis of an inter-instance relationship, and the directory server exchanges facility management data between instances on the basis of the inter-instance relationship.

Claims

1. A dynamic facility management system comprising:

a measuring-instrument reading device that performs input/output of signals from/to a measuring instrument that acquires information of a target facility handled by the system;

a first device that performs input/output of signals from/to the measuring-instrument reading device; and

a second device that has a set of software and performs input/output of signals from/to the first device,

wherein when the measuring instrument is connected to the measuring-instrument reading device, the second device determines software required by the system based on information of the measuring instrument and the second device transmits the software to the first device and the measuring-instrument reading device.

2. A dynamic facility management system comprising:

a measuring instrument that acquires information of a target facility handled by the system;

a lower level device that performs input/output of signals from/to the measuring instrument directly or through a communication network;

a higher level device that performs input/output of signals from/to the lower level device directly or through a communication network; and

a server that performs input/output of signals from/to the lower level device and the higher level device,

wherein the dynamic facility management system stores;

class information for each class including a class name comprising an item of information of the target facility handled by the system acquired by the measuring instrument and a name of an instance generated corresponding to the class name;

instance information for each instance including a name of the instance;

an arranged location of the instance, and the class name;

an inter-class relationship including a class name corresponding to higher level facility management data, a class name corresponding to lower level facility management data used to generate the higher level facility management data, how to use the lower level facility management data used to generate the higher level facility management data, and a name of a relation instance generated corresponding to a combination of a class corresponding to the higher level facility management data and a class corresponding to the lower level facility management data; and

an inter-instance relationship for each relation instance including a name of the instance arranged in the higher level device and a name of the instance arranged in the lower level device in the server,

when the measuring instrument is connected to the lower level device or the communication network that performs input/output of signals from/to the lower level device, a) the lower level device transmits a type of the measuring instrument and a purpose of connecting the measuring instrument which is an item of information of the target facility handled by the system to the server;

b) the server generates an instance by referring to the class information on the basis of the type of the measuring instrument and the purpose of connecting the measuring instrument which is an item of information of the target facility handled by the system;

c) the server searches the instance information and if the generated instance is not present, the server registers the generated instance and generates and registers a relation instance by referring to the inter-class relationship;

d) the server transmits the generated instance to the lower level device and the higher level device on the basis of the inter-instance relationship; and

e) the server exchanges the facility management data between the instances on the basis of the inter-instance relationship.

3. The dynamic facility management system according to claim 2, wherein

when the measuring instrument is removed from the lower level device or the communication network that performs input/output of signals from/to the lower level device, a) the lower level device transmits a name of the generated instance corresponding to the removed measuring instrument to the server;

b) the server updates the instance information so as to change a state of a predetermined instance to a state in which the facility management data is not processed and instructs the lower level device to delete an instance corresponding to the removed measuring instrument;

c) the lower level device deletes the instance corresponding to the removed measuring instrument; and

d) the higher level device and the server change a state of the instance corresponding to the removed measuring instrument to a state in which the facility management data is not processed on the basis of the instance information.

4. The dynamic facility management system according to claim 2, wherein all data of the relation instance are character strings.

5. The dynamic facility management system according to claim 2, wherein the target facility handled by the system is a circuit breaker in a transformer substation and the measuring device is a sensor that acquires a current passing through the circuit breaker and a palette switch operation signal as the information.
