Between communication.
The technical solution adopted in the present invention is.
The control system is disposed with 100 multi rack hydraulic supports along fully-mechanized mining working length direction, by an emulsion pump
Stand central fluid supply, there is provided power, it completed supporting roof during working face coal mining, promoted other mechanical equipments etc. dynamic
Make.The action of hydraulic support is connected each other, mutually constrained with the motion of coal-winning machine and transporter.
The control system is made up of main control computer, sub- control machine, hydraulic support etc..Every frame hydraulic support is entered by an estrade control machine
Row is monitored and controlled, and forms a computer electrichydraulic control subsystem；The serial communication interface of main control computer and all sub- control machines is equal
It is articulated in single communications bus, forms working surface hydraulic support and calculate mechanical electronic hydraulic dcs.
The hardware of the sub- control machine by single-chip microcomputer extension drive control circuit, monitoring feedback circuit, communication interface circuit,
Keyboard, LCD display, acoustic-optic alarm etc. form.Action to this hydraulic support is realized by operator control switch disk
Control sends order through communication interface to other sub- control machines, receives the hydraulic support execution that the sub- control machine of order draws oneself up
Corresponding action.Detection feedback circuit detects to the pressure of the oil cylinder of hydraulic support of action and displacement, forms closed circuit control.
Within actuation time, hydraulic support acts in place, the action of stopping immediately；If action is not in place, acoustic-optic alarm sends failure
Alarm, display show abort situation simultaneously, allow operating personnel to be handled in time.
The up-computer signal procedure provides complete API using reception mode is interrupted under Win95 environment
Application program interface function, programmer pass through these functions and hardware interfaces.Communication functions are to interrupt driving, data
Transmission process is easier to realize, reception processing mode mainly has inquiry and interrupt mode.During using inquiry mode, CPU will be surveyed constantly
Whether examination serial ports has data, to prevent reception serial data appearance mistake, omission, efficiency low；And then need not using interrupt mode
Serial ports is tested, once there are data to reach, CPU terminates current task, completes to operate by interrupt service routine.
The beneficial effects of the invention are as follows：The control system is designed based on Panasonic's FP series of PLC and GT01 touch screen technologies
Control system, it both ensure that the flexible of van compartment automatically controlled, and human-computer interaction real-time monitored realized again, in actual motion
In crossing, compartment expanding-contracting action is quick, steady, and observation is real-time, safe operation, stable performance, and reliability is high, has promotional value.
Brief description of the drawings
Fig. 1 is the hydraulic support Distributed Computer Control System theory diagram of the present invention.
Fig. 2 is the sub- control machine hardware principle of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, control system is disposed with 100 multi rack hydraulic supports along fully-mechanized mining working length direction, by an emulsion
Pumping plant central fluid supply, there is provided power, make it complete supporting roof during working face coal mining, promote other mechanical equipments etc. dynamic
Make.The action of hydraulic support is connected each other, mutually constrained with the motion of coal-winning machine and transporter.
Such as Fig. 2, control system is made up of main control computer, sub- control machine, hydraulic support etc..Every frame hydraulic support is by an estrade control machine
It is monitored and controls, forms a computer electrichydraulic control subsystem；The serial communication interface of main control computer and all sub- control machines
It is articulated in single communications bus, forms working surface hydraulic support and calculate mechanical electronic hydraulic dcs.
The hardware of sub- control machine drive control circuit, monitoring feedback circuit, communication interface circuit, key by single-chip microcomputer extension
Disk, LCD display, acoustic-optic alarm etc. form.Action control to this hydraulic support is realized by operator control switch disk
System sends order through communication interface to other sub- control machines, receives the hydraulic support execution phase that the sub- control machine of order draws oneself up
The action answered.Detection feedback circuit detects to the pressure of the oil cylinder of hydraulic support of action and displacement, forms closed circuit control.
In actuation time, hydraulic support acts in place, the action of stopping immediately；If action is not in place, acoustic-optic alarm sends failure report
Alert, display shows abort situation simultaneously, allows operating personnel to be handled in time.
In main control computer communicates with how sub- control machine, it is ensured that reliably communicated between main frame and slave, it is necessary to assure communication connects
Mouth has identification function.And the control bit SM2 in serial port of single chip computer control register SCON is exactly to meet this requirement
And set.And SM2 control bits only just work when the work in series mode 2 of MCS51 single-chip microcomputers is with mode 3, so more
Machine can only use both modes when communicating.When serial port in a manner of 2 or mode 3 receive, if SM2 is practised, represent that putting multimachine leads to
Telecommunication function position, at this moment there are two kinds of possible situations：Receive the 9th data for 1 when, data just load SBUF, juxtaposition RI=1 to
CPU sends interrupt requests；If receive the 9th data for 0 when, do not interrupt, information is lost.If SM2-0, connect
The 9th data either 0 or 1 received all produce the interrupt identification of RI=1, and the data received are fitted into SBUF.According to this
Function, it is possible to achieve the serial communication of MCS-51 application systems.
Host computer and slave computer send address value and data, interrupt mode reception address value sum using inquiry mode
According to.Frame format is baud rate 9600, no parity check, 8 data bit, 1 stop position.When each microcomputer is to single-chip microcomputer hair data, first
Send address signal " X " (XX is slave number), after the next single-chip microcomputer receives address signal, judge whether it is identical with Self address,
If difference is abandoned receiving, otherwise hair address itself is as answer signal to microcomputer, and after up-computer receives answer signal, judgement is
Target slave sends out control instruction or data, single-chip microcomputer then carry out response operation after receiving according to instruction.So it is achieved that
The point-to-point communication of PC and specified single-chip microcomputer in bus.
Up-computer signal procedure provides complete API applications using reception mode is interrupted under Win95 environment
Program interface functions, programmer pass through these functions and hardware interfaces.Communication functions are to interrupt driving, the transmission of data
Process is easier to realize, reception processing mode mainly has inquiry and interrupt mode.During using inquiry mode, CPU will constantly test string
Whether mouth has data, to prevent reception serial data appearance mistake, omission, efficiency low；And use interrupt mode then without test
Serial ports, once there is data to reach, CPU terminates current task, completes to operate by interrupt service routine.
