发明名称 COMMUNICATION NETWORK FOR ANALYZING DEVICE
摘要 PURPOSE:To drive each element by a transmitting data and a data being on a communication line, and to eliminate mutual interference between units by constituting a transmitting and receiving circuit for connecting the communication line, and a control part and a part to be controlled of an analyzing device, and providing transmitting and receiving elements separated electrically, on said circuit. CONSTITUTION:A communicating system for an analyzing device is constituted of a data processing device 20 and an analyzing device 21, and can be connected to an auto sampler 22 and other accessories as necessary. A transmitting and receiving circuit 16 is connected to said devices 20, 21, the sample 22, data processing device control part 17, analyzing device control part 18, and a mechanism control part 19, respectively. Also, each transmitting and receiving circuit 16 is connected to each other by a communication line 3, a measuring sample is fed successively to the device 21 from the sampler 22, a data is measured by the device 21, and the data is processed by the device 20. Also, a transmitting photocoupler 10 and a receiving photocoupler 12 separated electrically are provided on each transmitting and receiving circuit 16, the coupler 10 is driven by a transmitting signal 1, the coupler 12 is driven by a data on the communication line 3, and a mutual interference between units is prevented.
