Description
Technical field
The present invention relates to a kind of with the timing sequence control method for realizing multiple devices is counted, and belongs to automatic control technology neck
Domain.
Technical background
Timing sequence control to starting, the stopping of multiple devices, is the difficult point of this field, it is easy to cause frequently to open,
Stop same equipment.For to the opening, stop sequential control of three water pumps, it is ideal require be: exist guaranteeing that pipeline pressure is stablized
In zone of reasonableness, start idle time longest pump when pipeline pressure is low；Start one pump after after a period of time, pipeline pressure
It is also low, continue to start next pump, and so on；The time longest pump out of service when pipeline pressure is high, if stopping one
After collapsing after a period of time, pipeline pressure is also high, continues to stop next pump, and so on.Open, termination of pumping during follow and open
Idle time longest pump, time out of service longest pump are moved, avoids frequently opening, stop same pump and be used for a long time and deactivate
Same pump.But prior art realizes that the control of multiple devices is those skilled in the art there is no such technical solution
Technical problem urgently to be resolved.
Summary of the invention
It is an object of that present invention to provide a kind of with the timing sequence control method for realizing multiple devices is counted, by equipment
Starting, stopping number record numerical value, to reflect the operation of equipment or the length of dwell time；If reaching starting device item
Can judge that dwell time longest equipment should be started when part；If reach can judge to answer when stopping appointed condition it is out of service
Time longest equipment；It avoids and frequently opens, stops same equipment, equipment is made to be effectively protected in the application, solve existing skill
The above problem existing for art.
The technical scheme is that
A kind of timing sequence control method counting realization multiple devices passes through the starting to equipment, the number of stopping records
Numerical value, to reflect the operation of equipment or the length of dwell time；If can judge start when reaching starting device condition
The longest equipment of dwell time；If reaching can judge to answer time out of service longest equipment when stopping appointed condition.
The problem of equipment is water pump, and the time is recorded the runing time or dwell time length of water pump and in PLC,
It converts the starting of water pump, stop enumeration problem；By judge water pump starting, stop counting variable maximum value learn operation
Time or the longest water pump of dwell time；In the case where meeting condition of starting or stoping, water pump is carried out to start or stop control
System；Rising edge when being started using water pump is resetted to starting counting variable and other variables add 1 operation；Under when being stopped with water pump
It drops to reset along the stopping counting variable to water pump and adds 1 operation with other variables.
The present invention compares the control method for realizing that complicated timing is compared with simple counting, by starting to equipment,
The number of stopping records numerical value, to reflect the operation of equipment or the length of dwell time；If energy when reaching starting device condition
Enough judge that the longest equipment of dwell time should be started；If reaching can judge to answer the time out of service most when stopping appointed condition
Long equipment.It avoids and frequently opens, stops same equipment, equipment is made to be effectively protected in the application.
Numerical value is recorded the invention has the advantages that: the number by starting, stopping to equipment, to reflect the operation of equipment
Or the length of dwell time.If can judge that dwell time longest equipment should be started when reaching starting device condition；If reaching
To can judge to answer time out of service longest equipment when stopping appointed condition.It avoids and frequently opens, stops same equipment, make to set
Standby to be effectively protected in the application, the method can be suitable by the timing of the complicated multiple devices of the simple programming realization in PLC
Sequence control.
Detailed description of the invention
Fig. 1 each button grade display picture figure when being system initialization of the embodiment of the present invention；
Fig. 2 is PLC programming block diagram of the embodiment of the present invention；
Fig. 3 is the schematic diagram that the embodiment of the present invention judges counting variable maximum value.
Specific embodiment:
Below by embodiment, in conjunction with attached drawing, the invention will be further described.
In embodiment, a kind of with the timing sequence control method for realizing multiple devices is counted, the equipment is 3 water
Pump, comprises the following steps:
1. three water pumps are installed to scene, for controlling pipeline pressure；The electrical control cabinet of PLC controller and water pump is mounted on
In electric panel room, active station is mounted in master control room, and electrical control cabinet, PLC controller, the active station of pump are connected with each other；
2. establishing corresponding starting counting variable for every water pump, stopping counting variable；
3. to the starting counting variable of every water pump and stopping counting variable progress just in active station first before starting water pump
Beginningization assignment, it is necessary to start-up operation could be carried out to pumping system after being initialized, otherwise can not be started；Start in water pump system
Afterwards, variable can not be initialized again when in operating status, only water pump changes corresponding counting in starting, stopping
Variable；
4. " the starting variable " of three pumps carries out size comparison, when pipeline pressure is low, satisfaction opens water pump condition, starting " starting
Its corresponding " starting variable " is reset to " 0 " this water pump using water pump starting rising edge and corresponded to by that maximum water pump of variable "
" stop variable " add " 1 "；And " the starting variable " of other two water pumps and " stopping variable " all add " 1 "
5. " the stopping variable " of three pumps carries out size comparison, when pipeline pressure is high, meet pump condition of cutting off the water, stops " stopping
That maximum water pump of variable " stops failing edge using water pump and is reset to that " 0 " is corresponding " to open its is corresponding " stopping variable "
Dynamic variable " adds " 1 "；And " the starting variable " of other two water pumps and " stopping variable " all add " 1 "；
6. whole system only needs a water pump starting intervalometer and a pump to stop intervalometer, it can be completed three
The starting of pump stops needing.
The present invention passes through the variable size for judging every water pump, is started to the maximum water pump of variate-value, is stopped operation；
Using the variation of water pump run signal when starting, stopping, " 0 " is carried out respectively to " the starting variable " of water pump and " stopping variable "
Reset and add " 1 " operation.Reach the starting longest water pump of dwell time in any condition, time longest water pump out of service
Purpose.
Referring to Fig.1 it may first have to starting counting variable, stop counting variable initialization, then system start button
It can work, carry out system start-up operation, system is in operating status.If it is maximum to meet pump startup condition, starting counting variable
That pump using the starting rising edge of pump be that the starting variable of this pump is reset to 0, this pump stops variable and other pumps
Starting variable, stopping variable all adding 1, and every a pump startup interval time, pipeline pressure is also low, i.e. pump startup condition also meets
Just start the maximum pump of next counting variable automatically, and so on.The stopping control process of pump is identical to the starting control of pump
Process.
The present embodiment control block diagram, the block diagram such as attached drawing 2, attached drawing 3 for judging counting variable maximum value.
