Road is respectively connected to hand/auto state of equipment, operating status, malfunction, external interlocking and instrument port from top to bottom, and 2
Action command and acquisition shutdown command are opened in the access acquisition of DO switching channels, and 1 AI switching channels connection LED is shown；The PLC connects
Contact relay, and the relay connects actuator；The PLC link address dial-up and memory；Substation standard configuration RS485 communication
Interface, by the RS485 interface A of two core twisted-pair shielded wires and Intelligent wireless terminal B terminal connect, constitute have wireless transmission
The acquisition substation of function, wireless terminal is by being wirelessly connected central station wireless terminal, and central station wireless terminal is logical by RS485
Communication interface connects central station PLC.
Preferably, substation sends substation hand/auto state, operating status, fault state data to central station, receives simultaneously
Acquisition from central station opens, stops control instruction.
Preferably, the PLC and wireless terminal external world's 220V power supply.
A kind of intelligence instrument acquisition substation, operation include the following steps：
Step A, after hand/auto state is opened, order closing is opened when opening malfunction channel enters acquisition；When failure shape
After state is closed, the external interlocking channel of opening enters acquisition and opens order closing；Enter inter-interlock after outside interlocking channel is closed,
It opens when inter-interlock into acquisition and opens order closing, carried out in next step after inter-interlock channel is closed；
Step B, when central station issue halt instruction when, acquisition open order closing, when central station issue enabled instruction when into
Enter acquisition and open order opening, into next step；
Step C, acquisition opens order and opens countdown 5S, judges operating status, and internal connection is opened when operating status is closed
Lock；Inter-interlock is closed when operating status is opened.
The beneficial effects of the invention are as follows：The present invention with wirelessly replace it is wired so that the upgrading of old control system at
This reduction；System centre station is handled by the required state that wireless collection sends over, control function block exports result
To control equipment executing agency, while this result is sent to central station, to be monitored and operate in host computer, ensure that
The stability of system；Transformation process is carried out by equipment substep local flow improvement, is influenced on the overall operation of original system smaller or without shadow
It rings.
Detailed description of the invention
Fig. 1 is intelligence instrument acquisition substation schematic diagram of the present invention；
Fig. 2 is intelligence instrument acquisition substation control function block control flow chart of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
