Description of drawings
Fig. 1 is a circuit block diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1: the present invention includes infrared carbon sulfur analyzer host side single chip circuit and coreless induction furnace end single chip circuit, host side single chip circuit and coreless induction furnace end single chip circuit all are connected with optical transmission circuit and optical receiving circuit respectively, and the optical transmission circuit of host side single chip circuit and optical receiving circuit are connected the optical receiving circuit and the optical transmission circuit of coreless induction furnace end single chip circuit respectively by one road light transmitting fiber.
This device has used 1 group of light transmitting fiber, totally 2, sends signal and received signal separately; Single chip circuit in the host machine part sends the command signal of control coreless induction furnace work, and optical transmission circuit is the circuit that electric signal is transformed into light signal, and optical receiving circuit is the circuit that light signal is transformed into electric signal; The status signal of the work of each valve and reception manual operation coreless induction furnace sent to main frame and the light signal that receives main frame by light emission and light-receiving then when the single chip circuit of coreless induction furnace part was the control high-frequency combustion.
Principle of work is as follows: the kindling signal that is at first received a coreless induction furnace by the single-chip microcomputer of HFS, single-chip microcomputer just sends to optical transmission circuit with this signal, by optical transmission circuit this electric signal is transformed into corresponding light signal, this light signal is by the optical receiving circuit of fiber optic transmission to host machine part, optical receiving circuit will receive to such an extent that light signal is reduced into electric signal and gives single-chip microcomputer then, after the single chip circuit of host machine part receives this signal, send operation instruction signal and give optical transmission circuit, optical transmission circuit becomes light signal to this digital signal transition, this light signal is given the optical receiving circuit of coreless induction furnace part by light transmitting fiber, this optical receiving circuit is transformed into electric signal with the light signal that receives, then this electric signal is sent to single-chip microcomputer, the single chip circuit of coreless induction furnace part is controlled each valve working on the coreless induction furnace according to this electric signal, to reach the analysis requirement.
