Abstract

PURPOSE:To improve the reliability of the whole of a terminal unit by providing a control program to control peripheral equipment, a monitoring program, a recovering program, an interface means and the like and recovering the peripheral equipment. CONSTITUTION:At a terminal unit 1, an operating system 5, a control program group 6 corresponding to peripheral equipment, a monitoring program group 7 and a recovering program group 7 and a recovering program group 8 are provided. A program 6 is activated by the system 5 as needed, the information to inform that it is normal, through interface means 9, 10 and 11 for a constant time is sent, and then, a normal flag is ON. A program 7, when the normal flag is OFF, namely, when the normal information from the peripheral equipment is not sent, increases an abnormal counter by 1. When the number of the times of abnormalities exceeds the allowable value, a recovering program 8 corresponding to each peripheral equipment is activated, the recovering processing in accordance with each peripheral equipment is executed and the reliability of the whole of the device 1 can be improved.
