The problem of, while the technical staff for also facilitating state acquisition module determines that rapidly problem starts to repair.
Detailed description of the invention
Fig. 1 is a kind of method for monitoring state of Research for Feeding Raw Materials System of the embodiment of the present invention；
Fig. 2 is the method for monitoring state of another Research for Feeding Raw Materials System of the embodiment of the present invention.
Specific embodiment
It is with reference to the accompanying drawing and specific real in order to make those skilled in the art more fully understand technical solution of the present invention
Applying example, the present invention is described in further detail.
Existing Research for Feeding Raw Materials System is provided with some state-detection points, goes acquisition state to detect by state acquisition module
The status data of point, once acquisition state data occur it is abnormal, Research for Feeding Raw Materials System just can not feeding, although of short duration be unable to feeding
It will not influence blast fumance, but be unable to feeding for a long time, the production of blast furnace will be had an impact.The analysis found that acquisition shape
There is the problem of exception is not Research for Feeding Raw Materials System itself in state data, but the problem of state acquisition module.Therefore we need
The problem of distinguishing state acquisition module simultaneously quickly solves, and ensures the normal production of blast furnace.
As shown in Figure 1, the embodiment of the invention provides a kind of Research for Feeding Raw Materials System method for monitoring state, Research for Feeding Raw Materials System
Several state-detection points are provided with, each state-detection point is provided with state acquisition module, and each state acquisition point is adopted
With following method for monitoring state, specifically include:
Pass through the measured value of state of state acquisition module timing acquiring state-detection point；
It is less than or equal to preset threshold in response to measured value of state, generates the threshold value monitored results of state-detection point；
Lower than pre-set interval minimum or it is higher than pre-set interval peak in response to measured value of state, generates state-detection point
Section monitored results.
Wherein, the time interval of the measured value of state of state acquisition module acquisition state test point is 500 milliseconds.In reality
In, the acquisition interval time can be set according to the actual situation on site.
Wherein, preset threshold, according to the technological requirements, feeding material list and the working of a furnace requirement, it is true by blast furnace furnace superintendent or technique factory director
It is fixed, it is set by shift foreman.Operating technology person is responsible for executing monitoring by monitoring interface.
Wherein, preset threshold 0 illustrates that state is adopted when the measured value of state of state acquisition module acquisition is 0 or negative value
Collection module occurs breaking or the failure of short circuit, generates corresponding monitored results, while blinking red lamp can be set；
Wherein, pre-set interval is a value range, when the measured value of state of state acquisition module acquisition is greater than preset range
The maximum value of value or minimum value less than preset range value, then it is assumed that measurement failure occurs in state acquisition module, generates corresponding
Monitored results, while can be set amber light flashing.
Such as the regular event range fascinated of chute is between 30-60 degree, pre-set interval is 15-85 degree, less than 15 degree or
Person is greater than 85 degree, then it is assumed that measurement failure occurs in state acquisition module.
Staff repairs according to monitored results notification technique personnel, and technical staff is examined accordingly according to state status
It looks into, state acquisition module can have been repaired faster.
As shown in Fig. 2, the embodiment of the invention provides another Research for Feeding Raw Materials System method for monitoring state, in above-mentioned implementation
On the basis of example, the handover information of reception state test point is further comprised, the step of switching state test point.
