Description
Technical field
The utility model relates to industrial automations, and in particular to a kind of novel intelligent communication switching controller.
Background technique
When forming measurement and control network using the remote control apparatuses such as sensor, detector, what traditional measurement and control network used
Communication modes are the industrial bus of RS-232 RS485 serial ports, recycle microcontroller to carry out networking, but use this side
Formula poor universality, and it is isolated to internet.If by TCP/IP network server is equipped in every equipment, volume is big, cost
It is high and be not easily accomplished.
PLC is common equipment in remote control apparatus, and PLC often connects many acquisition equipment, if using mesh
Preceding measurement and control network carries out the transmission of data, and PLC needs to adopt the reading for carrying out data in a polling mode one by one, not only speed
Slowly, the burden of PLC is also very heavy.
Utility model content
The purpose of this utility model is that: a kind of novel intelligent communication switching controller is provided, is solved at present using PLC
Measurement and control network in, PLC needs to carry out speed slow technical problem when reading data using polling mode one by one.
The technical solution adopted in the utility model is as follows:
A kind of novel intelligent communication switching controller, the controller are separately connected actuating station and control terminal, realize and execute
The information of end and control terminal is transmitted, and the controller includes protocol converter, and the protocol converter includes processor, storage
Device, underlay communication port and upper layer communication port, the protocol converter is connect by underlay communication port with actuating station, described
Protocol converter is connect by upper layer communication port with PLC controller, the PLC controller pass through Ethernet switch with it is described
Control terminal connection, the processor that actuating station is sent data in protocol converter are unpacked, and the data after unpacking are stored up
It deposits into memory, PLC controller can directly take out data from the memory, then be transmitted to by Ethernet switch
The control terminal, equally, control terminal send data to PLC controller, and PLC controller issues control command and stores to described
In memory, processor is issued to actuating station after being packaged.
Further, protocol converter upper layer communication port includes ethernet port, the underlay communication port packet
Include RS-232 serial ports, RS-422 serial ports and RS-485 serial ports.
Further, digital input channel is additionally provided on the protocol converter.
Further, the agreement that the PLC controller transmitting order to lower levels uses is Modbus TCP, and the actuating station receives life
Enabling the agreement used is Modbus RTU.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are: using this programme can be with
Effectively the data in measurement and control network are connected into internet, while can be to avoid PLC using poll one by one using this scheme
Mode brought by disadvantage, promoted speed, mitigate the burden of PLC, increase data bandwidth, shorten data acquisition week
Phase.
