Patent attributes
An exemplary computer monitoring system includes a central processing unit (CPU) connected to a computer, a first microprocessor, a second microprocessor, and a select switch connected to a terminal device. The CPU is connected to the select switch via the first microprocessor and the second microprocessor respectively for transmitting data. When one of the first and second microprocessors is halted, the other one of the first and second microprocessors is selected by the select switch under the control of the CPU. The CPU sends a reset signal to the halted microprocessor to reset it. A monitoring method using the computer monitoring system for improving stability and reliability of the computer monitoring system is disclosed.
