Abstract

There is described a system for sending, via a communication network, data originating from a monitoring of equipment in a network-inaccessible location. The system comprises a first interface device to be operated in a network-inaccessible location and comprising: sensors for monitoring a first equipment; a processor connected to the sensors for generating a data packet from the monitoring; and a local input/output (I/O) device for sending the data packet. The system further comprises a second interface device, to be displaced from the network-inaccessible location to a network-accessible location, comprising a local I/O device for receiving the data packet from the first interface device; and a network-connected I/O device to deliver the data packet via the communication network.

Claims

1. A system for sending, via a communication network, data originating from a monitoring of equipment in a network-inaccessible location, the system comprising:

a first interface device for monitoring a first equipment and generating data packets from the monitoring;

a second interface device for monitoring a second equipment and generating data packets from the monitoring,

at least one other interface device adapted for mutual communication with both the first interface device and the second interface device and adapted for synchronizing the data packets of the first interface device with the data packets of the second interface device,

wherein;

the first interface device and the second interface device are adapted for mutual communication through which the data packets from the first interface device and the data packets from the second interface device synchronize;

at least one of the first interface device and the second interface device is adapted;

to be displaced to a network-accessible location;

to deliver, via the communication network, the data packets;

to receive, via the communication network, a receipt signal indicating the data packets that were delivered;

the one of the first interface device and the second interface device which received the receipt signal is adapted to communicate the receipt signal to the other one of the first interface device and the second interface device; and

upon receiving the receipt signal from one of the first interface device and the second interface device, any interface device synchronizes its data packets with the one of the one of the first interface device and the second interface device except for the data packets identified in the receipt signal.

2. A method for transmitting data originating from a network-inaccessible location to a processing center, the method comprising:

monitoring equipment by a first interface device in a network-inaccessible location;

generating an identifiable data packet from the monitoring;

recording the identifiable data packet on the first interface device;

providing a local communication between the first interface device and a second interface device, the second interface having at least another identifiable data packet recorded thereon;

upon providing the local communication between the first interface device and the second interface device, sending a receipt signal from the second interface device to the first interface device;

upon providing the local communication between the first interface device and the second interface device, sending the other identifiable data packet from the second interface device to the first interface device for recording thereon, thereby synchronizing the identifiable data packets recorded on the first interface device and excluding from the synchronizing the identifiable data packets which are identified in the receipt signal as received by at least one of the first interface device and the second interface device;

sending the identifiable data packet from the first interface device to the second interface device for recording thereon;

displacing the second interface device to a network-accessible location for sending the identifiable data packet to a processing center;

upon sending the identifiable data packet to a processing center, receiving a receipt signal of any identifiable data packet received by the processing center.

3. The method of claim 2, wherein providing a local communication between the first interface device and second interface device comprises:

providing a local communication between the first interface device and a third interface device;

sending the identifiable data packet from the first interface device to the third interface device;

providing a local communication between the third interface device and the second interface device; and

sending the identifiable data packet from the third interface device to the second interface device.

4. The method of claim 3, wherein the third interface device comprises one or more interface devices, wherein if the third interface device comprises two or more interface devices, a local communication is provided at least temporarily between two of them.

5. The method of claim 4, wherein upon providing the local communication between the first interface device and the third interface device, the third interface device sends any identifiable data packet recorded thereon to the first interface device;

and

wherein upon providing the local communication between the third interface device and the second interface device, the second interface device sends any identifiable data packet recorded thereon to the third interface device.
