Data acquisition system and transmission control device
First Claim
1. A data acquisition system for collecting data over a network, from data generator devices at a plurality of respective data generating points, into a data utilization device at a data utilization point, comprising at least:
- a plurality of transmit-side transmission control devices, each including a CPU, on the data generating point side of the network for sending data generated by the data generator devices to the data utilization point side; and
a receive-side transmission control device, including a CPU, on the data utilization point side for aggregating the data from the plurality of transmit-side transmission control devices, and sending the data to the data utilization device,wherein the transmit-side transmission control devicereceives notification of an allowable data transmission quantity from the receive-side transmission control device,retains that allowable data transmission quantity,adjusts the data quantity sent from the data generator device so as to fit within that allowable data transmission quantity range,generates a request to change the allowable transmission data quantity based on a transfer need request from a data generator device among the data generating points, andsends the request to change the allowable transmission data quantity to the receive-side transmission control device,wherein the receive-side transmission control deviceretains the respective allowable data transmission quantities for the plurality of transmit-side transmission control devices,upon receiving the request to change the allowable transmission data quantity, reallocates the allowable data transmission quantities among the transmit-side transmission control devices to fit within the data processing load range within the data utilization point, andnotifies the corresponding transmit-side transmission control devices of the reallocated allowable data transmission quantities.

Abstract
A transmit-side transmission control device for sending data generated by a data generator device to a data utilization point receives and retains notification of the allowable data transmission quantity from a receive-side transmission control device, and adjusts the data quantity sent from the data generator device so as to fit within that allowable data transmission quantity range, and/or when a request is issued to change that data transmission quantity, the receive-side transmission control device is notified of that allowable data transmission quantity change request. The receive-side transmission control device retains the respective allowable data transmission quantities for transmit-side transmission control device, and when a change request is issued, reallocates the allowable data transmission quantities for all transmit-side transmission control devices to fit within the data processing load range stored beforehand within the data utilization point, and notifies the corresponding transmit-side transmission control device of these reallocated allowable data transmission quantities.
