With the progress of science development, the controls of various loads come into computerize gradually. Most of equipment makes use of programmable Logic Controller or Ethernet network in the past, which connect with computer. It is mature in industrial applications, but still unsuitable in the general monitoring system . The project focuses on this problem to provide a complete solution.
The fundamental structure of system runs in the environment of popular windows by personal computer, using high-level interface program between human being and machine. The operator can be easy to operate system by using high-level interface program language. It makes use of series-port output and input signals via cable to specific module, and supplies interface program between human and machine. Consequently, remote equipment can be controlled to achieve expected purpose.
