| Abstract: | With an example of elevator remote monitoring system,introduced the technology of serial communication between the computer and the PLC,and the technology of communication between computers through the PSTN. The application was developed by using VC6 0. The system used a multimedia timer to make the elevator running status data being collected on time. These methods enhanced the real time capability and the reliability of the system. |
