Advantage of the present utility model: enhance the reliability of data transmission in automatic control system, extend the distance of data transmission so that in automatic control system, each parts layout at the scene is wider, and position is more flexible, reduce position limitation, it is simple to management, debugging maintenance safe and reliable.
Accompanying drawing explanation
Fig. 1 is that structure of the present utility model forms schematic diagram.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
In traditional automatic control system, the output of rotary encoder is usually direct-connected with PLC, longer in both distances, or when on-the-spot electrical Interference is more, the data that rotary encoder reads often are difficult to transmit smoothly to PLC.
The automatic control system using high speed counting module that the utility model proposes, as it is shown in figure 1, include: PLC, master station module, high speed counting module, fieldbus, rotary encoder, converter and motor；
PLC uses Rhizoma Sparganii Q series of PLC, and master station module uses Rhizoma Sparganii Q series CC-Link master station module, and rotary encoder uses PEPPERL FUCHS rotary encoder, and high speed counting module just Rhizoma Sparganii CC-Link high speed counting module, fieldbus is Rhizoma Sparganii CC-Link fieldbus；PLC connects master station module, and master station module connects each high speed counting module by CC-Link fieldbus；High speed counting module is as the substation of master station module, by CC-Link fieldbus and master station module communication；Each high speed counting module is connected with one or two rotary encoder, and the A phase of rotary encoder exports with B phase and connects corresponding high speed counting module.
Principle of the present utility model is: there is the photoelectric code disk of axle at rotary encoder You Yige center, the groove that annular is logical, dark is had on it, photoemission and receiving device is had to read, obtain four groups of sine wave signals and be combined into A, B, C, D tetra-phase, 90 degree of phase contrasts (being 360 degree relative to a cycle) of each sinusoidal wave difference, by C, D signals reverse, be superimposed upon A, B biphase on, stabilization signal can be strengthened；Separately often transfer out a Z phase pulse to represent zero reference position.Due to the biphase difference of A, B 90 degree, to differentiate the forward and reverse of encoder, by zero pulse, the zero reference position of encoder can be obtained by comparing A phase in front or B phase front.In this example, A.B two is connected high speed counting module, for forward backward counter, judges forward and reverse and tests the speed.
In actual connection, 5 feet of Rhizoma Sparganii CC-Link high speed counting module connect the A phase of rotary encoder and export, and 8 feet connect the B phase of rotary encoder and export.
The data of rotary encoder pass through substation, and---delivering path of CC-Link fieldbus----master station module---PLC, so that data transmission is reliable, transmission range increases.
It addition, master station module connects converter by Rhizoma Sparganii CC-Link fieldbus, converter connects motor as the substation of master station module, converter.Converter is obtained in that the data of motor, is transferred to PLC by CC-Link fieldbus, and the transmission of motor data (voltage, electric current etc.) is the most more stable reliably.
This utility model can obviously improve the reliability of data transmission in automatic control system, extend the distance of data transmission so that in automatic control system, each parts layout at the scene is wider, and position is more flexible, reduce position limitation, it is simple to management, debugging maintenance safe and reliable.
