Background technique
Multimode refers to the sensor of different acquisition mode, as string type sensor, poor resistive sensing and sensor.It is all
Sensor has collection value and becomes measured value by conversion and calibration, and the sensor of different mode may have adopting for different number
Set value (difference resistance 2, string formula needs input value and multiple collection values) and different formula, while each sensor needs one
It examines and determine table and is used for calibrated meter.
Therefore, it in intelligent instrument system development process, needs in face of various sensors, while having many based on sensing
The early warning alarm of device measured value and quadratic formula calculate, and traditional algorithm needs a large amount of developments, and formula maintenance is not also very square
Just.
One, after the prior art has the disadvantage in that existing equipment acquisition data, often through acquisition terminal by the number of acquisition
According to being sent to computer, then calculate measurement result.
Two, the acquisition data source data that only support entity sensor monitors, and majority of case is to really need survey
Amount the result is that being obtained by the common survey calculation of multiple sensors.
Three, measurement value sensor is monitored the influence of environment sudden change, and unreasonable fluctuation occurs in measured value.
Four, sensor monitor value exceeds safety line, and alarm is not in time.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of measuring management method of multimode intelligence instrument, which solve
Multiple formula iteration and recursive management support the sensor of various formula to configure and examine and determine, and support virtual-sensor, public
Formula is easy to maintain.
The present invention is to solve above-mentioned technical problem by following technical proposals: a kind of measurement pipe of multimode intelligence instrument
Reason method, which is characterized in that itself the following steps are included:
Step 1, multimode intelligent instrument system are integrated into upper terminal；
The applicable calculation formula of various kinds of sensors is arranged in multimode intelligent instrument system, the normal of formula is arranged for step 2
Measure parameter and variable parameter；
Measurement point, measurement point position, the sensor of access, connection biography is arranged in step 3 in multimode intelligent instrument system
The port of sensor, the agreement for connecting sensor are configured to calculate the calculation formula of sensor measurement, configuration calculation formula
The value of middle constant parameter；
Virtual-sensor is arranged in step 4；
Step 5, the measurement range of setting various kinds of sensors acquisition data, the safe early warning value of measurement, Measurement results are previous
A fluctuation range with the latter；
Step 6, setting various kinds of sensors acquire the temporal frequency of measured value；
Temporal frequency, calculation method, the precondition of various kinds of sensors calculating achievement value is arranged in step 7；
Step 8, control acquisition terminal acquire data according to configuration result；
Step 9, the calculation formula by being arranged are calculated as producing result value according to the measured value of acquisition；
Step 10, according to the sensor measurement range automatic fitration abnormal measurement data of setting, the data of over-limit condition
Automatically alarm is provided.
Preferably, the constant parameter is the correction certified value of measurement of correlation point
Preferably, the variable parameter is the measured value of sensor.
Preferably, the calculation formula needs to quote multistage calculating achievement, needs that achievement is calculated using recursive algorithm
Value.
The positive effect of the present invention is that: invention defines the formula of dynamic measurement point and instrument calibration system
System, uses the general intelligent Pattern completion acquisition equipment of various modes formula.The present invention is using virtual-sensor and repeatedly
The virtual-sensor in generation is by the secondary calculating and management standardization of measured value, to enormously simplify based on measured value, to various
The Real-time running system for relying on measured value has obvious help.
Specific embodiment
Present pre-ferred embodiments are given below, in order to explain the technical scheme of the invention in detail.
The measuring management method of multimode intelligence instrument of the present invention the following steps are included:
Step 1, multimode intelligent instrument system is integrated into upper terminal, in ARM, PC, PDA；
The applicable calculation formula of various kinds of sensors is arranged in multimode intelligent instrument system, the normal of formula is arranged for step 2
(constant parameter is the correction certified value of measurement of correlation point for amount and variable parameter；Variable parameter is the measured value of sensor).
Measurement point, measurement point position, the sensor of access, connection biography is arranged in step 3 in multimode intelligent instrument system
The port of sensor, the agreement for connecting sensor are configured to calculate the calculation formula of sensor measurement, configuration calculation formula
The value of middle constant parameter.Measured value is that sensor is directly measured without the value Jing Guo any processing.Achievement value is sensor measurement
Value by the result that is converted to.
Virtual-sensor is arranged in step 4；Virtual-sensor is suitable for the median of one or multisensor calculating, such as single
Aggregate-value, the multiple sensors of a sensor for a period of time calculate jointly generates end value etc..The inessential setting of virtual-sensor,
Use when needing to calculate or show the achievement value that real sensor can not directly obtain.
Step 5, setting various kinds of sensors can acquire the measurement range of data, the safe early warning value of measurement, Measurement results
The previous fluctuation range with the latter.
Step 6, setting various kinds of sensors acquire the temporal frequency of measured value.
Temporal frequency, the calculation method, precondition (such as measured value of various kinds of sensors calculating achievement value is arranged in step 7
It whether there is, the other sensors measured value that need to quote or achievement value etc.)；
Step 8, control acquisition terminal acquire data according to configuration result.
Step 9, the calculation formula by being arranged are calculated as producing result value according to the measured value of acquisition.If the meter being related to
It calculates formula and needs to quote multistage calculating achievement, need that achievement value is calculated using recursive algorithm.
Step 10, can be with measurement range automatic fitration abnormal measurement data according to the sensor of setting.Over-limit condition
Data provide alarm automatically.
The present invention is integrated in equipment or the host computer of various kinds of sensors acquisition system, the sensor that measurement point is acquired
Value is converted to achievement value according to the calculating of the formula of setting.
The present invention supports the definition of measurement point formula, and multiple variable parameters are arranged for calculating achievement value, together in formula
When the instrument calibration of measurement point is completed by the configuration of constant.Calculation formula is arranged in instrument and virtual instrument, virtual instrument
Measured value can derive from the calculated result value of actual instrumentation, and then generate multilayer instrument nesting, and recursive algorithm is supported by minimum
Instrument collection result step-by-step calculation instrument calculated result value to the end.
