<p>PURPOSE:To prevent the entire system from being stopped if any computer fails by forming the system to transmit signals from each small size computer through a network, and operate elements attached to it in accordance with information from the small size computers. CONSTITUTION:Small size computers 6-10, 13 are respectively attached to each element 1-5, 14, and connected to each other by a network 11 provided with a network controller 12. The small size computers 6-10, 13 are the provided with communication among open another under the action of the network controller 12, and operate each element 1-5, 14 to receive data from necessary elements as necessary. Consequently, if any computer fails, the failure influences a minimum of elements, and there is no need for stopping the entire system. Since the functions of the system are decentralized, if trouble occurs, discovery of cause of the trouble is easy, and the down time of associated parts can be shortened.</p> |
