| Abstract: | The Service-evaluating System Based on AT89C series single-chip computer consists of a host, a lot of window evaluating device, and a PC. Evaluating host is composed of main control, data storage, 232 level conversion unit, power input and 485 bus interface. Window evaluating device and PC is used as slave, it receives and processes data from host, and relevant LED is controlled according to star-level information in local data. The communication between host and slave is realized through polling mode. |
