Abstract
A multi-stage data logging system comprising a telecommunications stage for receiving, processing, and compressing data from one or more input channels, a recorder stage for storing said data to a memory device, a distribution stage for retrieving said stored data and distributing said data to one or more output channels, and a plurality of interface paths linking said three stages to one another. Different stages of the system can be located wide distances apart and the interface paths linking the three stages can be automatically switched to achieve fault tolerance of the system.
Claims37
A multi-stage data logging system comprising:
- a) a telecommunications (“telecom”) stage receiving input from a plurality of input channels;
- b) a recorder stage having one or more recorders, at least one recorder storing data associated with input received from at least one of said plurality of input channels;
- c) a distribution stage providing access to data stored in the recorder stage;
- d) a first interface linking the telecom and the recorder stages and a second interface linking the recorder and the distribution stages;
- wherein at least two stages of the system are physically separable and in operation can be located wide distances apart.
A multi-stage data logging system comprising:
- a) a first means for receiving signals from one or more input channels;
- b) a second means for recording data associated with received signals;
- c) a third means for retrieving stored data and distributing retrieved data to one or more output channels;
- wherein at least two of said first, second, and third means are physically separable and can operate wide distances apart.
A data logger, comprising:
- a telecommunication device receiving input from a plurality of data sources;
- a processor converting input from said plurality of data sources to one or more data formats;
- a memory for storing converted data corresponding to the received input from said plurality of data sources;
- a communication path;
- and
- a server transferring stored data from one or more of said plurality of data sources via the communication path to at least one remote user.
A method for accessing information in at least one digital logger storing data associated with input from a plurality of input channels, comprising:
- at a Web server having access to said at least one digital logger, receiving a request for retrieval of stored data from a client;
- retrieving stored data in accordance with the received request;
- and
- transferring the retrieved data to the client.
A method for operating a multi-stage data logging system having:
- a telecom stage receiving input from a plurality of input channels;
- a recorder stage having two or more recorders, at least one recorder storing data associated with input received from the plurality of input channels and at least one backup recorder;
- a distribution stage providing access to data stored in the recorder stage;
- and a first interface linking the telecom and said one or more recorders of the recorder stages and a second interface linking the recorder and the distribution stages;
- the method comprising:
- detecting a malfunctioning recorder in the recorder stage;
- automatically switching interface links from the detected malfunctioning recorder to said backup recorder to ensure uninterrupted operation of the system;
- and
- without disrupting the operation of the system replacing the detected malfunctioning recorder with a functioning recorder.
A method for increasing the recording capacity of an operating multi-stage data logging system having:
- a telecom stage having telecom blocks capturing input from at most N input channels;
- a recorder stage having one or more recorders, said recorders having maximum recording capacity of M (M≦N) channels;
- a distribution stage providing access to data stored in the recorder stage;
- a first network-based or four-wire-based interface linking the telecom and the recorder stages;
- and a second interface linking the recorder and the distribution stages;
- the method comprising:
- (a) without disrupting the operation of the system attaching to said first interface at least one recorder so that the combined capacity of the recorders in the recorder stage is equal to or exceeds N channels.
