Abstract An electric equipment drive control system for controlling the drive of the electric equipment, wherein the drive control equipment includes a pulse signal generator for generating a pulse signal having the pulse signal corresponding to the voltage value at the power source, a microprocessor circuit which acts synchronously with the pulse signal outputted from the pulse signal generator and which executes a program prepared with a prerequisite that the voltage at the power source is a predetermined voltage, and a drive circuit for turning on and off the connection of each circuit in the electric equipment and the power source. The pulse signal generator increases the frequency of the pulse signal when the power voltage is higher than the predetermined voltage, and decreases the frequency of the pulse signal when the power voltage is lower than the predetermined voltage.
An electric equipment drive control system comprising an electric equipment and a drive control equipment for controlling the drive of the electric equipment by using a microcomputer, wherein said drive control equipment is provided with a pulse signal generator for generating a pulse signal having a predetermined frequency when the power voltage at said electric equipment presents a predetermined voltage, for generating a pulse signal having a higher frequency when said power voltage is higher than said predetermined voltage, and for generating a pulse signal having a lower frequency when said power voltage is lower than said predetermined voltage, wherein said drive control equipment is provided with a microcomputer for receiving the pulse signal as clock signal output from said pulse signal generator, for executing a program prepared with a prerequisite that the voltage at said power source is said predetermined voltage, and for determining the timing and time interval to apply a current to each circuit in said electric equipment, and wherein said drive control equipment is provided with a drive circuit for turning on and off the connection of each circuit in said electric equipment and said power source on the basis of the timing and time interval determined by the microprocessor.
