Description of the drawings
Fig. 1 is existing control system software architecture diagram；
Fig. 2 is the system construction drawing of the present invention.
Specific implementation mode
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
As shown in Fig. 2, the present invention provides a kind of control system calibration method, can this method just by examining and determine control software
Really identification and processing input signal, realize the calibrating to control system, need to establish input signal map section, defeated for storing
Enter signal；Output signal map section is established, for storing output signal；The control software of control system, which obtains, comes from input signal
The signal of map section, the control output signal obtained after control software is handled are stored in output signal map section.Input signal
For live input signal or analog input signal, the mode that output signal map section exports output signal is physics output or mould
Quasi- output.
Wherein, live input signal is according to signal caused by live physical device, and analog input signal is to utilize meter
Signal caused by the various live input signals of calculation machine simulation.The mode of the live input signal of simulation is also varied.Simulation
There are three types of modes for input signal：Stochastic simulation, automatic imitation and semi-automatic simulation.Detailed annotation is as follows：
Stochastic simulation：
I.e. on computers, various live input signals are artificially simulated.Such as：Motor running signal, electromotor overload letter
Number and the signals such as motor three-phase operating current/voltage.
Automatic imitation：
Such as moisturizing pond water level control：When small pump motor start-up, simulation moisturizing pool water level is risen by certain speed,
When moisturizing pool water level reaches termination of pumping water level, moisturizing pump motor is out of service；After moisturizing pump motor is out of service, according to
Preset speed, moisturizing pond water level decreasing；When moisturizing pond water level decreasing is to specified water level, start moisturizing pump motor moisturizing.
Simulation in cycles in this way, so that it may realize that simulation moisturizing pool water level automatically controls, to examine whether controlling software design meets
Design requirement.
Semi-automatic simulation：
The signal for being exactly is automatic imitation, signal be artificial stochastic simulation.It is with moisturizing pond water level control above
Example：Water level automatic imitation, but the various failures of moisturizing motor then stochastic simulation.Such as moisturizing electromotor overload, under-voltage and phase shortage
Etc. failures, to examine whether controlling software design meets design requirement.
The principle of the present invention is：No matter all it is first to be stored in input letter from live input signal or analog input signal
Number map section.Control software obtains the signal from input signal map section, and the control obtained after control software is handled is defeated
Go out signal and is stored in output signal map section.According to working method determine the signal of output signal map section be physics output or
Simulation output.Four kinds of working methods can be generated based on the present invention：Prototype mode, half analog form A, half analog form B and complete
Analog form.Four kinds of operating mode detailed annotations are as follows：
Prototype mode：
Signal from scene is not quoted directly in control software directly, but is first stored in input signal map section
In.Control software is the signal quoted in input signal map section, and indirect input signal of the reference from scene.
The output control signal of generation is stored according to the signal of input signal map section by processing by control software
In output signal map section.
Physics output will export the signal transmission in map section to various output control modules, control the fortune of various equipment
Row, to realize true physical control.
Half analog form A：
Various signals from scene are not quoted directly in control software directly, but are first stored in input signal and are reflected
It penetrates in area.Control software is the signal quoted in input signal map section, and indirect input signal of the reference from scene.
The output control signal of generation is stored according to the signal of input signal map section by processing by control software
In output signal map section.Simulation output is passed in the signal transmission in output signal map section to simulation output area
Transport to various output control modules.
Since output control signal is there is no just true output to control output module, physical equipment will not be controlled, therefore
In testing and control software process, any damage will not be generated to physical equipment, ensure that the safety of physical equipment.
Half analog form B：
The various signals from scene are simulated using miscellaneous equipment, the signal at these simulation scenes is stored in input map section
In, control software is also that simulation on-site signal is obtained from input signal map section.
The output control signal of generation is stored according to the signal of input signal map section by processing by control software
In output signal map section.
Physics output will export the signal transmission in map section to various output control modules, to realize true physics control
System.
Full analog form：
The various signals from scene are simulated using miscellaneous equipment, the signal at these simulation scenes is also to be stored in input to reflect
It penetrates in area, control software is also to obtain on-site signal from input signal map section.
The output control signal of generation is stored according to the signal of input signal map section by processing by control software
In output signal map section.Simulation output is passed in the signal transmission in output signal map section to simulation output area
Transport to various output control modules.
Since output control signal is there is no just true output to control output module, physical equipment will not be controlled, therefore
In testing and control software process, any damage will not be generated to physical equipment, ensure that the safety of physical equipment.
No matter under which kind of working method, input signal map section, control software and output signal map section are all public
's.Exactly this reason can examine the correctness of control software, while can ensure that the safety of physical equipment again.
When carrying out signal calibrating to control system, some analog signals need to detect its variation speed in detection process
Degree can send out alarm signal and block signal, these signals are to participate in controlling automatically after signal intensity speed is more than certain value
System.
Or by taking moisturizing pond water level control as an example：It is more than certain to be such as set according to actual conditions moisturizing pond SEA LEVEL VARIATION speed
After value, judges water level transmitter exception, send out water level transmitter abnormal alarm signal at this time, while being latched moisturizing pump motor.
After setting moisturizing pond SEA LEVEL VARIATION velocity anomaly value in control software, it can be examined by changing SEA LEVEL VARIATION speed
Can control software accurately detect moisturizing pond SEA LEVEL VARIATION speed, when its pace of change is more than the moisturizing pond set in control software
When SEA LEVEL VARIATION velocity anomaly value, can control software send out water level transmitter abnormal alarm signal and can be latched moisturizing electronic
Machine, to achieve the purpose that examine and determine water level transmitter abnormal identification and processing.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, it is noted that all
All any modification, equivalent and improvement made by within the spirit and principles in the present invention etc. should be included in the guarantor of the present invention
Within the scope of shield.
