To achieve the above object, the technical solution adopted in the utility model is that annular IO control systems include IO master controls
Device, multiple I O board and communication line, I O board include IO inlet wires, signal output interface and signal input interface, multiple I O boards according to
It is secondary to be connected by communication line, wherein the signal output interface of previous I O board connects the signal input interface of next I O board, first
The signal input interface of individual I O board connects I/O master by communication line, and the signal output interface of last I O board passes through
Communication line connects I/O master, and IO inlet wires connect unit under test respectively.
Communication line is optical fiber.
Operation principle of the present utility model is：I O board connects external equipment and carries out data acquisition by IO inlet wires, and I O board is adopted
The data for collecting are connected to I/O master by optical fiber telecommunications line, after the data message in each I O board of I/O master comprehensive analysis
Control instruction is sent by optical fiber telecommunications line respectively to each I O board, the control to external equipment is realized.
The beneficial effects of the utility model are：Annular IO control systems of the present utility model, will by optical fiber telecommunications line
Each I O board is connected and connects I/O master, forms the IO control systems of annular, can effectively utilize the communication capacity of fiber optic communication,
Complicated various wiring in traditional I/O control system is reduced, the energy loss of circuit is reduced, is easy to system maintenance.
Brief description of the drawings
Fig. 1 is the schematic diagram of this annular IO control system.
Specific embodiment
In conjunction with accompanying drawing, the utility model is described in further detail.
As shown in figure 1, annular IO control systems, include I/O master, multiple I O boards and communication line, I O board is included
IO inlet wires, signal output interface and signal input interface, multiple I O boards pass sequentially through communication line series connection, wherein previous I O board
Signal output interface connects the signal input interface of next I O board, and first signal input interface of I O board passes through communication line
Connection I/O master, the signal output interface of last I O board connects I/O master by communication line, and IO inlet wires connect respectively
Connect unit under test.
Communication line is optical fiber.
I O board connects external equipment and carries out data acquisition by IO inlet wires, and the data that I O board is collected pass through optical fiber communication line
Road is connected to I/O master, and each I O board is given by optical fiber telecommunications line after the data message in each I O board of I/O master comprehensive analysis
Control instruction is sent respectively, realizes the control to external equipment.
Preferred embodiment of the present utility model described in detail above, it will be appreciated that the ordinary skill people of this area
Member just can make many modifications and variations without creative work according to design of the present utility model, therefore, all this technology necks
