The technical solution of the present invention will be described in detail with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Example 1
The utility model provides an air separation plant key process parameter circulation alarm device, refers to fig. 1, including interconnect's alarm module and timing module, alarm module can report to the police, and the timing module can assist alarm module circulation to report to the police, can realize that key parameter is according to the time cycle alarm of setting for after transfiniting, reminds operating personnel.
Specifically, the alarm module is used for generating alarm information to alarm when the process variable exceeds a first preset value, and it can be understood that in the existing control systems of the air separation device DCS or PLC and the like, when the process technological parameters exceed the limit, the alarm module needs to give an alarm to remind workers to adjust in time, so that the safety is ensured.
In the scheme, the alarm module comprises a detection unit, a trigger unit and a processing unit, wherein the detection unit is used for detecting whether a process variable exceeds a first preset value and generating a trigger signal when the process variable exceeds the first preset value; the RS trigger is used for responding the trigger signal and outputting alarm information; and the alarm unit is used for responding to the alarm information and giving an alarm.
It can be understood that the detection unit is used for detecting whether the process variable exceeds a first preset value in real time, namely whether the process variable exceeds a limit value, if so, a trigger signal is generated and transmitted to the RS trigger, the RS trigger outputs alarm information, the alarm unit is triggered to alarm, and the overrun alarm is realized.
It should be noted that, in order to realize the circular alarm, the scheme is provided with a timing module, the timing module is used for responding to alarm information for timing and generating reset information after the preset time is exceeded, and the RS trigger responds to the reset information for resetting and generates the alarm information again for alarm when the process variable exceeds the first preset value.
It can be understood that the RS trigger in the alarm module is reset in response to the reset information, and the detection unit detects whether the process variable exceeds the first preset value after the RS trigger is reset, and generates the trigger signal again when the process variable exceeds the first preset value. After the RS trigger is reset, even if an operator carries out silencing operation or suspends operation, after the preset time, the RS trigger can respond to the trigger signal again to generate alarm information, alarm again and cycle in sequence until the process parameters are recovered to be normal.
The preset time may be, for example, 5 minutes, which is not limited by the present disclosure.
In practical application, the input end of the RS trigger is connected with the detection unit, and the output end of the RS trigger is connected with the alarm unit. On the basis, the timing module comprises a TON timer, and the TON timer is connected with a reset pin of the RS trigger.
For example, referring to fig. 1, taking the cyclic alarm of the CO2 content after the air exits the purifier as an example, when the process variable air _1201 value is greater than 1, the RS trigger is set, the Q1 output is output, the molecular sieve CO2 high alarm is output, the flow chart picture flickers, and an alarm sound is emitted. After 300S the RS flip-flop is reset and if the value of AIRA _1201 is still >1, the alarm is triggered again. If the AIRA _1201 value is less than 1, the RS trigger is reset, the alarm signal disappears, and after the operator confirms or silences the alarm signal, the alarm is triggered again if the AIRA _1201 value is greater than 1 after the set time of 300S.
It should be noted that the timing module utilizes a TON timer to time, and generates information after exceeding a preset value, which belongs to the prior art, and there is no software improvement, and many timers in the prior art can implement the above functions, and are not described herein again; in a similar way, the detection unit is used for detecting whether the process variable exceeds a first preset value or not, generating a trigger signal when the process variable exceeds the first preset value, and only judging whether the value exceeds a threshold value or not.
Example 2
Compared with the embodiment 1, the air separation device key process parameter circulating alarm device is characterized in that an alarm module is also used for generating early warning information for alarming when a process variable exceeds a second preset value; wherein the degree to which the second preset value deviates from the normal operating value is less than the degree to which the first preset value deviates from the normal operating value.
It will be appreciated that the present solution may be used to set a pre-alarm for important parameters, and may set a pre-alarm value (second preset value) that deviates from normal operating values but does not far reach the alarm value. When the process parameter reaches the pre-alarm value due to some abnormal reason, the operator is reminded to process the process parameter, so that more serious accidents are avoided.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications or substitutions do not depart from the scope of the invention in its corresponding aspects.
