The warning interlocking corresponding with described sequence step is labeled as " 1 ", and not corresponding with described sequence step warning interlocking is labeled as " 0 ";
Arrange according to the order contrary with the interlocking of reporting to the police all " 1 " and " 0 ", forms assignment binary number;
Described assignment binary number is converted to decimal number, obtains the decimal number of giving for described sequence step.
It should be noted that, a corresponding warning interlocking of sequence step is for one or more, the corresponding sequence step of interlocking of reporting to the police can be also one or more, the corresponding decimal number of multiple sequence step can equate also can be unequal, even if two sequence step correspondences identical warning interlocking, described two corresponding decimal numbers of sequence step also can equate or be unequal.
Step b, described decimal number is converted to binary number, and using " 1 " in described binary number and " 0 " respectively as the All Alerts corresponding activation condition of interlocking, go to step d.
Concrete, described binary number is identical with assignment binary number, according to the order identical with forming described assignment binary number, using " 1 " in described binary number and " 0 " respectively as the All Alerts corresponding activation condition of interlocking, , first chain activation condition of reporting to the police is first that binary number is counted from right to left, namely lowest order, second chain activation condition of reporting to the police is the second that binary number is counted from right to left, namely time low level, the rest may be inferred, last chain activation condition of reporting to the police is binary number last position of number from right to left, namely most significant digit, so, in step a, arrange according to the order contrary with the interlocking of reporting to the police " 1 " and " 0 " all in described assignment binary number.Now, if described warning interlocking is warning interlocking corresponding to described sequence step, " 1 " in described binary number as with the described warning corresponding activation condition of interlocking; If described along the interlocking of reporting to the police for not corresponding with described control step warning interlocking, " 0 " in described binary number as with the described warning corresponding activation condition of interlocking.
Step c, the parameter of interlocking according to described warning, produce trigger value " 1 " or the trigger value " 0 " of reporting to the police and interlocking, and goes to step d.
Concrete, need to first obtain the parameter that described warning is interlocked, described warning interlocking parameter can utilize the various instrument on the equipment of being arranged on to obtain; Whether the parameter that then judges described warning interlocking reaches default alarm criteria, if so, produces the trigger value " 1 " of the interlocking of reporting to the police, and if not, produces the trigger value " 0 " of the interlocking of reporting to the police.
D, described trigger value and described activation condition are done to AND operation, if operation result is " 1 ", report to the police, if operation result is " 0 ", do not do any operation.
When equipment is carried out to technological improvement, if need to change the warning interlocking of equipment, due to composing for sequence step decimal numeral time, its assignment is according to having comprised all warning interlockings of equipment, only need to revise the corresponding decimal number of sequence step, can the conversion to binary number by decimal number, and then revise the activation condition that needs the warning interlocking of changing, can increase or delete the warning interlocking that described sequence step is corresponding.For example, need to increase warning interlocking corresponding to described sequence step, only need to, by the activation condition of described warning interlocking, by original " 0 ", be revised as " 1 ", the interlocking of this can being reported to the police is increased in described numerical control step.
Visible, the method of the sequence warning interlocking that the embodiment of the present invention provides, with a decimal number and the binary number that equates with it, replace the activation condition of existing sequence warning interlocking method, and " 1 " in described binary number and " 0 " are respectively as the All Alerts corresponding activation condition of interlocking, when revising the interlocking of reporting to the police, can directly revise decimal number corresponding to sequence step, by decimal number is converted to binary number, can revise accordingly the activation condition of the interlocking of reporting to the police, can increase or delete the warning interlocking that described sequence step is corresponding, do not need as prior art just like that, need to multiple steps or multiple warning interlocking be done repeatedly and be deleted, and then reduce and revise the workload of reporting to the police while interlocking, reduce wrong generation.
Further embodiment of this invention discloses a kind of method of concrete reduction furnace sequence warning interlocking, in the sequence process of described reduction furnace, supposes that described reduction furnace has eight interlockings of reporting to the police (actual conditions not only have eight warnings to interlock) altogether, is respectively:
TCS flow deviation, H2 flow deviation, N2 flow deviation, mixed feeding pressure is low, and exhaust temperature is high, and infrared thermometer temperature is low, and high-temperature water pressure is low, and high-temperature water pressure is high.
As shown in Figure 3, the method comprises:
Step a1, according to eight report to the police interlocking, for sequence step, give decimal number 210, go to step b1.
Concrete, by the All Alerts permanent order of interlocking, that is: TCS flow deviation, H2 flow deviation, N2 flow deviation, mixed feeding pressure is low, and exhaust temperature is high, and infrared thermometer temperature is low, and high-temperature water pressure is low, and high-temperature water pressure is high.
Warning interlocking corresponding to described sequence step has four, is respectively:
H2 flow deviation, exhaust temperature is high, and high-temperature water pressure is low, and high-temperature water pressure is high.
Not corresponding with described sequence step warning interlocking also has four, is respectively:
TCS flow deviation, mixed feeding pressure is low, and exhaust temperature is high, and infrared thermometer temperature is low.
The warning interlocking corresponding with described sequence step is labeled as to " 1 ", and not corresponding with described sequence step warning interlocking is labeled as " 0 ", can be accordingly:
TCS flow deviation ... 0
H2 flow deviation ... 1
N2 flow deviation ... 0
Mixed feeding pressure is low ... 0
Exhaust temperature is high ... 1
Infrared thermometer temperature is low ... 0
High-temperature water pressure is low ... 1
High-temperature water pressure is high ... 1
Arrange by the order contrary with the interlocking of reporting to the police above-mentioned all " 1 " and " 0 ", forms assignment binary number 11010010, transforms the decimal system and be: 210, and decimal number corresponding to described sequence step is 210.
Because the value volume and range of product (needing to report to the police and do not need the warning interlocking of reporting to the police) of warning interlocking corresponding to multiple described sequence steps is likely identical, likely not identical yet, therefore,, for multiple sequence steps, the decimal number of giving can be also similar and different.
Step b1, described decimal number 210 is converted to binary number 11010001, described binary number 11010001 is identical with assignment binary number 11010001, and distribute activation condition, , using " 1 " in described binary number 11010010 and " 0 " according to the order identical with forming assignment binary number 11010010 respectively as TCS flow deviation, H2 flow deviation, N2 flow deviation, mixed feeding pressure is low, exhaust temperature is high, infrared thermometer temperature is low, high-temperature water pressure low with high eight the corresponding activation conditions of interlocking of reporting to the police of high-temperature water pressure, now, first activation condition of reporting to the police chain TCS flow deviation is several 11010010 first from right to left of binary number, namely lowest order 0, the activation condition of second chain H2 flow deviation of reporting to the police is the second that binary number 11010010 is counted from right to left, namely time low level 1, the rest may be inferred, last high activation condition of chain high-temperature water pressure of reporting to the police is binary number 11010010 last position of number from right to left, namely most significant digit 1, so, eight report to the police interlocking and activation condition be corresponding thereto:
TCS flow deviation ... 0
H2 flow deviation ... 1
N2 flow deviation ... 0
Mixed feeding pressure is low ... 0
Exhaust temperature is high ... 1
Infrared thermometer temperature is low ... 0
High-temperature water pressure is low ... 1
High-temperature water pressure is high ... 1
Now, only need distribute in order, needn't optionally distribute again, to facilitate alarm flow.
Then, go to step d1.
Step c1, according to TCS flow deviation, H2 flow deviation, N2 flow deviation, mixed feeding pressure is low, and exhaust temperature is high, and infrared thermometer temperature is low, high-temperature water pressure is low, the parameter of high eight interlockings of reporting to the police of high-temperature water pressure, gives binary number " 1 " or " 0 " for described warning interlocking, then goes to step d1.
For example, for the warning interlocking of TCS flow deviation, if default normal TCS flow is 300Nm3/h ± 10Nm3/h, the alarm criteria of default TCS flow deviation is for being less than 290Nm3/h and being greater than 310Nm3/h.When the instrument of monitoring TCS flow records TCS flow and is less than 290Nm3/h or is greater than 310Nm3/h, can produce a trigger value 1, when the instrument of monitoring TCS flow records TCS flow within the scope of 300Nm3/h ± 10Nm3/h time, can produce a trigger value 0.
Concrete, with H2 flow deviation, TCS flow deviation and exhaust temperature height are example, in step a1, the warning of H2 flow deviation is interlocked corresponding activation condition for " 1 ", the warning of TCS flow deviation is interlocked corresponding activation condition for " 0 ", the warning that exhaust temperature is high is interlocked corresponding activation condition for " 1 ", if in step c1, H2 flow deviation warning interlocking trigger value is " 1 ", the trigger value of TCS flow deviation warning interlocking is " 1 " or " 0 ", the high trigger value of reporting to the police interlocking of exhaust temperature is " 0 ", to described H2 flow deviation, the warning that TCS flow deviation and exhaust temperature are high interlock corresponding activation condition and described H2 flow deviation, the trigger value of the warning interlocking that TCS flow deviation and exhaust temperature are high does AND operation, that is:
H2 flow deviation: 1 ∩ 1=1;
TCS flow deviation: 0 ∩ 1=0 or 0 ∩ 0=0;
Exhaust temperature is high: 1 ∩ 0=0.
Visible, for the warning interlocking of needs warning, as H2 flow deviation warning interlocking, as long as its warning interlocking parameter reaches alarm criteria, its warning interlocking trigger value is " 1 ", can report to the police; For the warning interlocking that does not need to report to the police, as TCS flow deviation, report to the police and interlock, no matter it is reported to the police, interlocking parameter is how, its operation result is " 0 ", all can not report to the police; For the warning interlocking of reporting to the police for needs, the interlocking of reporting to the police as exhaust temperature is high, as long as it reports to the police interlocking, parameter does not reach alarm criteria, its interlocking trigger value of reporting to the police is " 0 ", can not report to the police.
The sequence that the embodiment of the present invention provides is reported to the police in the method for interlocking, if need to increase the warning interlocking of the TCS flow deviation of reduction furnace, only need to revise the corresponding decimal number of sequence step.
When sequence step is given a decimal number for this reason, need to change the former mark " 0 " of the warning interlocking of TCS flow deviation into " 1 ", become:
TCS flow deviation ... 1
H2 flow deviation ... 1
N2 flow deviation ... 0
Mixed feeding pressure is low ... 0
Exhaust temperature is high ... 1
Infrared thermometer temperature is low ... 0
High-temperature water pressure is low ... 1
High-temperature water pressure is high ... 1
Arrange by the order contrary with the interlocking of reporting to the police above-mentioned all " 1 " and " 0 ", form assignment binary number 11010011, the conversion decimal system is: 211, and decimal number corresponding to described sequence step changes 211 into, can complete the modification to described sequence step warning interlocking.For other sequence steps of TCS flow warning interlocking correspondence, also only need to change accordingly the decimal number of giving to it, can complete the modification to described sequence step warning interlocking activation condition.
Visible, described reduction furnace is being done to technological improvement, when interlocking is reported to the police in change, not needing the each warning interlocking to each sequence step to do increases or deletes again, only need to change to the decimal number of giving of corresponding sequence step, then can the conversion to binary number by decimal number, and then modification needs the activation condition of the warning interlocking of changing, compared to the method for existing sequence warning interlocking, the disclosed method of the embodiment of the present invention, in the technological improvement of making reduction furnace, can greatly reduce workload, raise the efficiency and be not prone to mistake.
It should be noted that, the report to the police method of interlocking of sequence disclosed in this invention, is not limited in the sequence that is applied in reduction furnace and reports to the police in interlocking, and any sequence that needs is reported to the police in the equipment of interlocking, all can apply the report to the police method of interlocking of sequence disclosed in this invention.
