The working principle and control method of system.
Summary of the invention
To solve the above problems, the present invention will be explained in detail the more Can plate collection control dresses of flame-proof type level Four band conveying multi-touch screen
The control method set.
The technical solution that the more Can plate centralized control equipment control methods of flame-proof type level Four band conveying multi-touch screen of the present invention use
It is:
Flame-proof type level Four band conveys the more Can plate centralized control equipment control methods of multi-touch screen, including SIEMENS PLC, and following N can
It is 1,2,3,4, it is characterized in that: load MODBUS, parking and picture secondary control method；
N can be 1,2,3,4, respectively represent 1,2,3,4 grade of band conveying.
(1), load parking, picture and MODBUS grade control method；
Contain load MODBUS, parking and picture secondary control method in this control method.
(1.1) MODBUS grade control method described in includes: after powering on, to be instructed by MBUS_CTRL, and MODBUS is arranged
The mode of main equipment communications protocol, baud rate, even-odd check, time-out time, starting circulation read-write timer；
After being electrically connected on centralized control equipment, instructed by MBUS_CTRL, the mode of setting MODBUS main equipment communications protocol,
Baud rate, even-odd check, time-out time parameter, and start circulation read-write timer；
It is instructed, the field control of the digital quantity input port on PLC, console is controlled, manually, certainly by BLKMOV_B
Dynamic, emergent stopping, reset, upper key, lower key, left button, right key, confirmation key, N is opened at scene, N is stopped at scene, console
Open N, console stops N, contact feedback N, band-type brake N, smog N, coal piling N, the starting acousto-optic early warning of digital output port, motor N,
Communication failure N, watering N, the discrete data in bit memory area, analog quantity/digital quantity conversion expansion module output port voltage
And current digital quantity data, it is moved in the variable store area of PLC；
By the reading instruction of MBUS_MSG, by each pullswitch on Can-1, Can-2, Can-3 and Can-4 plate
Location, preceding sideslip N, middle sideslip N, rear sideslip N, speed N, motor N temperature, roller N-1 temperature, roller N-2 temperature and roller N-3
Temperature data is read in the variable store area of PLC；
Again by the write command of MBUS_MSG, the above-mentioned data in the variable store area of PLC are write into touch screen N respectively again
Register in, and touch screen N communication failure occur when outputting communication failure n-signal；
By BLKMOV_B data block move, by the data of the input and output side of PLC and analog quantity/digital quantity
The conversion collected voltage and current data of expansion module are moved in the variable store area of PLC, then are read by MBUS_MSG
The each pullswitch address acquired on Can-1, Can-2 and Can-3 plate, preceding sideslip N, middle sideslip N, rear race are read in instruction fetch
The variable that inclined N, speed N, motor N temperature, roller N-1 temperature, roller N-2 temperature and roller N-3 temperature data read PLC is deposited
Reservoir area；Then by MBUS_MSG write instruction, the above-mentioned data in the variable store area of PLC are respectively written into touch again
In the register for shielding N, and the outputting communication failure n-signal when touch screen N communication failure occurs.
This control method is using PLC as main website, and each touch screen is slave station, carries out data biography by MODBUS communications protocol
Defeated.
(1.2), the parking secondary control method includes: emergency mobile forces stop signal and disastershutdown signal；
In two kinds of situation, one is stopping in emergency, one is disastershutdowns for parking.
If emergency mobile forces stop signal includes: master console, local control box, emergency stop switch or pullswitch are any on touch screen
It presses, then emergency mobile forces stop signal=1；After reset key on master console or touch screen, emergency mobile forces stop signal=0；
It stops in emergency and refers to when there is emergency, press master console, local control box, the emergency stop switch on touch screen
Or press with each pullswitch being arranged on pipeline, all band conveyings shut down, avoid that bigger accident occurs.
If disastershutdown signal includes: disastershutdown n-signal=1, disastershutdown signal=1；
The disastershutdown n-signal includes: contact feedback N control method, after centralized control equipment starting and delay, if N
There is contact fault in grade band conveying, if keeping monitoring, disastershutdown N=1, if cancelling monitoring, disastershutdown N=0；Electric current
Overcurrent N and overcurrent time are to, under-voltage or over-voltage and the under-voltage or over-voltage time arrives, is band-type brake N, smog N, coal piling N, speed N, preceding
