Function control device managing energy consumption for a mobile system powered by a battery
First Claim
1. A function control device in a mobile system for crime and disaster prevention, said mobile system being propelled by an electric motor and utilizing a battery as a sole power source, said function control device comprising:
- the power source;
a microcomputer for continuously controlling overall operation of the mobile system;
motor driving means, connected to said microcomputer, for moving said mobile system by rotating the electric motor;
first comparator means, connected to said power source and said microcomputer, for comparing a voltage level of said power source with a motor driving minimum reference voltage, said microcomputer deactivating said motor driving means when said first comparator means outputs a signal indicating that said voltage level of said power source is below said motor driving minimum reference voltage.

Abstract
A function control device for a mobile system which uses a battery. The control device includes a microcomputer for controlling an overall operation of the mobile system, a first voltage comparing portion for comparing a voltage level of the power source with a motor-driving minimum reference voltage and a second voltage comparing portion for comparing the voltage level of the power source with a gas sensor minimum reference voltage. The device also includes a motor driving portion for moving the mobile system, a gas sensing portion for sensing gas leaks an intruder sensing portion for sensing whether an intruder is present, a fire sensing portion for sensing fires and an alarm for generating a warning sound when at least one of the above problems is sensed. When the voltage level of the battery falls below the gas sensing reference voltage and/or the motor driving reference voltage, the system deactivates the gas sensor and/or the motor driver.
