Abstract

A data acquisition system having a plurality of remote data gathering devices each of which communicates according to a respective defined communications protocol. An object database memory containing data for all of the data gathering devices is provided. Protocol drivers stored in the memory may be retrieved and stacked to form a layered protocol driver in accordance with established ISO/OSI standards. A common messaging interface is interposed between adjacent protocol drivers in the stack and a common database interface is interposed between the protocol drivers and the database memory.

Claims

1. A data storage and management system for use with a data acquisition system including a plurality of remote data gathering devices, each of the plurality of remote data gathering devices communicating according to a respective defined communications protocol, the data storage and management system comprising:

a machine having a memory containing an object database for storing information representing a plurality of device objects each associated with a respective data gathering device, each device object including;

(a) at least one protocol stack defining the communications protocol of the respective data gathering device;

(b) at least one poll configuration defining the data to be retrieved from the respective data gathering device; and

(c) at least one device data folder defining the groups of data found within the respective data gathering device.

2. The data storage and management system according to claim 1 wherein the database further contains information representing the history of the remote data gathering devices and each device object further includes at least one device history which defines history objects for the respective data gathering device.

3. The data storage and management system according to claim 1 wherein each of said at least one protocol stack contains a respective ordered list of protocol drivers defined according to ISO/OSI protocol layering definitions.

4. The data storage and management system according to claim 3 wherein the database stores action data, parameter data and event data for each of the defined protocol drivers.

5. The data storage and management system according to claim 1 wherein the database stores at least one folder containing a plurality of device objects.

6. The data storage and management system according to claim 1 wherein the database stores in each device object information characterizing the respective data gathering device, including its manufacturer and model type.

7. The data storage and management system according to claim 1 wherein the database stores for each device object an audit device object containing alarm and event information for the respective data gathering device.
