摘要:
It is to provide a method of transferring a program to an internal memory from an external memory at a high speed and at a high efficiency. The external memory has program data to be transferred and set data of a dedicated register including wait information of the program data. A microcomputer has an internal ROM to which a transfer program for transferring data to an internal RAM from the external memory is prestored. If a CPU in the microcomputer accesses set data for the dedicated register at the head address of the external memory and receives the set data including the wait information of data to be transferred when reset is released, the data is transferred to the internal RAM via an address bus and a data bus by executing the transfer program in the internal ROM. An area of the transferred data in the internal RAM is rearranged at an area including a boot area and a vector table and the program data is executed by the CPU.
摘要:
An electricity demand prediction system includes electricity usage data collection means, production schedule storage means, model creation means, and short-term electricity demand prediction means. The electricity usage data collection means collects electricity usage data of each device and causes electricity usage data storage means to store the collected electricity usage data. The model creation means creates an electricity amount calculation model of each prescribed product type for each device on the basis of the electricity usage data stored in the electricity usage data storage means and a past production schedule stored in the production schedule storage means. The short-term electricity demand prediction means computes future electricity demand for each device on the basis of the electricity amount calculation model created by the model creation means and a future production schedule stored in the production schedule storage means.

摘要:
A control device for a rolling plant, which is capable of reducing the pouring amount of cooling water by pouring cooling water at timing of high cooling efficiency when a material being rolled is cooled, and thereby being capable of saving the energy consumption. The control device includes a plurality of rolling stands that are arranged in tandem on a rolling line to roll the material being rolled of a metallic material conveyed on the rolling line, and inter-stand cooling systems that are provided between the plurality of rolling stands to pour cooling water onto the conveyed material being rolled. The inter-stand cooling systems are configured so that the pouring amount of cooling water poured from the inter-stand cooling system positioned on the upstream side on the rolling line is larger, and the pouring amount of cooling water poured from the inter-stand cooling system positioned on the downstream side is smaller.
