Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a flowchart of an emergency processing system and method for a strip steel cleaning section according to the present invention, and as shown in fig. 1, the emergency processing method for signals of the strip steel cleaning section of the present embodiment includes the following steps:
and S01, receiving a feedback signal of the strip steel cleaning section.
In a continuous annealing strip steel production line, a strip steel cleaning section has a plurality of feedback signals, the feedback signals are used for detecting the normal operation of the strip steel production line, and in many times, the feedback signals of the strip steel cleaning section are often affected by external factors to generate jitter or signals, so that wrong production line fault information can be generated, and the production line is accidentally stopped, and the feedback signals of the strip steel cleaning section generally comprise a smoke exhaust mode feedback signal, a cleaning mode feedback signal and a heating mode feedback signal which respectively represent the operation states of a smoke exhaust section, a cleaning section and a heating section. In the smoke discharging section, the cleaning section and the heating section, the operation feedback signals of the monitoring fan, the pump, the flow feedback signals, the temperature feedback signals, the liquid level feedback signals, the pressure feedback signals and other feedback signals can be divided, and each feedback signal can be received by the emergency processing system.
And S02, analyzing and processing the feedback signal, judging whether the feedback signal has a fault, and if so, sending relevant information of the feedback signal.
In step S02 of this embodiment, after the emergency processing system receives the various feedback signals in step S01, the emergency processing system analyzes various related information of the feedback signals, where the related information includes fault information and location information, such as a temperature feedback signal existing in the heating section, and once the temperature feedback signal information fails, data is abnormal or interrupted, the emergency processing system captures the information, and then obtains a time length of the temperature feedback signal failure, compares the failure time of the feedback signal with a preset time of the feedback signal, and if the failure time of the feedback signal is less than or equal to the preset time of the feedback signal, the failure is automatically eliminated; and if the fault time of the feedback signal is greater than the preset time of the feedback signal, a fault exists. For example, the failure time is 3 seconds, and after 3 seconds, the signal failure disappears, which indicates that the influence of the outside on the signal disappears and the signal returns to normal. Therefore, normally, a preset time is set, for example, 15 seconds, when the actual fault time length is greater than 15 seconds, it is indicated that the fault of the feedback signal cannot automatically disappear, and the faulty feedback signal may cause the production system of the strip steel to perform a false action of stopping production, so that the production line is stopped for maintenance, and the production efficiency is reduced, at this time, the emergency processing system may send related information of the feedback signal. And when the actual fault time length is less than the preset time, the fault of the feedback signal disappears automatically, the production system of the strip steel cannot be caused to stop producing, and therefore the emergency treatment system does not process the fault.
And S03, receiving and analyzing the received relevant information of the feedback signal, and starting a signal shielding button corresponding to the received relevant information to eliminate the feedback signal of the strip steel cleaning section.
In step S03 of this embodiment, when the emergency processing system receives and analyzes the relevant information of the received feedback signal, it can know which feedback signal is in problem according to the relevant information, so as to start the corresponding signal shielding button and eliminate the signal, so that the feedback signal in problem does not affect the normal operation of the strip steel production line.
Example two
As another embodiment of the present invention, fig. 2 is a schematic structural diagram of an emergency processing system for strip steel cleaning section signals according to a second embodiment of the present invention, and as shown in fig. 2, the emergency processing system for strip steel cleaning section signals according to the present embodiment includes a signal obtaining unit, configured to receive a feedback signal of a strip steel cleaning section; the signal analysis processing unit is used for analyzing and processing the feedback signal and judging whether the feedback signal has a fault or not, if so, sending out relevant information of the feedback signal, and if not, not processing; the signal shielding button is used for eliminating a feedback signal of the strip steel cleaning section; and the control unit is used for receiving and analyzing the related information of the received feedback signal and starting a signal shielding button corresponding to the received feedback signal.
It is worth noting that besides the control unit controls the signal shielding button, the field staff can see the relevant information of the feedback signal sent by the signal analysis processing unit, and can also control the signal shielding button manually to actively eliminate the feedback signal of the strip steel cleaning section.
Further, the signal analysis processing unit is further configured to compare the failure time of the feedback signal with a preset time of the feedback signal, and if the failure time of the feedback information is less than or equal to the preset time of the feedback signal, the failure is automatically eliminated; if the fault time of the feedback signal is longer than the preset time of the feedback signal, a fault exists, and the feedback signal generally comprises a smoke exhaust mode feedback signal, a cleaning mode feedback signal and a heating mode feedback signal which respectively represent the operation states of a smoke exhaust section, a cleaning section and a heating section. In the smoke discharging section, the cleaning section and the heating section, the operation feedback signals of the fan, the pump, the flow feedback signals, the temperature feedback signals, the liquid level feedback signals, the pressure feedback signals and other feedback signals are monitored, for example, the temperature feedback signals exist in the heating section, once the temperature feedback signals fail, data is abnormal or interrupted, the emergency processing system can capture the data, then the time length of the temperature feedback signals is obtained, for example, the failure time is 3 seconds, the signal failure disappears after 3 seconds, the influence of the outside on the signals disappears, and the signals are recovered to be normal. Therefore, normally, a preset time is set, for example, 15 seconds, when the actual fault time length is greater than 15 seconds, it is indicated that the fault of the feedback signal cannot automatically disappear, and the faulty feedback signal may cause the production system of the strip steel to perform a false action of stopping production, so that the production line is stopped for maintenance, and the production efficiency is reduced, at this time, the emergency processing system may send related information of the feedback signal. And when the actual fault time length is less than the preset time, the fault of the feedback signal disappears automatically, the production system of the strip steel cannot be caused to stop producing, and therefore the emergency treatment system does not process the fault. That is, if the failure time is less than or equal to the preset time, the signal analysis processing unit does not process the failure time; and if the fault time is greater than the preset time, the signal analysis processing unit sends out relevant information of the feedback signal, wherein the relevant information comprises fault time information and position information.
To sum up, the embodiment of the invention provides an emergency processing system and method for a strip steel cleaning section, when a signal acquisition unit receives a feedback signal, a signal analysis processing unit can judge the feedback signal and send out relevant information of the feedback signal, a control unit starts a corresponding signal shielding button according to the relevant information to eliminate the feedback signal, and in the cleaning section, the production line is stopped due to abnormal feedback signal, but the fault of the production line is not caused by the fault of the production line, so that after the feedback signal is eliminated, the continuous operation of the production line can be ensured, and the system and method have good practicability.
