Problems solved by technology

[0002] In the continuous annealing strip production line, continuous production needs to be maintained, and there are many sensors for feedback signals in the strip cleaning section, so a lot of feedback signals will be fed back during the production process, and due to the high temperature and dust in the production environment Influence, each sensor is prone to malfunction. Once a certain sensor fails, not only will it not be able to detect normally, but the related feedback signal will also fail abnormally. What is more serious will cause the corresponding cleaning mode of the cleaning section to fail to start, which will affect the continuous annealing. The cleaning section of the strip steel production line cannot run, resulting in shutdown failures and a serious reduction in production efficiency

Embodiment 1

[0026] figure 1 It is a flow chart of the emergency treatment system and method of the strip cleaning section of the present invention, as figure 1 As shown, the emergency treatment method of the strip cleaning section signal of the present embodiment comprises the following steps:

[0027] S01. Receive a feedback signal from the strip cleaning section.

[0028] In the continuous annealing strip steel production line, there are many feedback signals in the strip steel cleaning section, which are used to detect the normal operation of the strip steel production line. In many cases, the feedback signals of the strip steel cleaning section are often affected by external factors. Shattering or signals occur, which will generate wrong fault information of the production line, resulting in unexpected stoppage of the production line, and the feedback signals of the strip cleaning section usually include the smoke exhaust mode feedback signal, the cleaning mode feedback signal and th...

Embodiment 2

[0034] As another embodiment of the present invention, figure 2 The schematic structural diagram of the emergency treatment system for the signal of the strip cleaning section provided in Embodiment 2 of the present invention, as shown in figure 2 As shown, the emergency processing system of a strip cleaning section signal provided by this embodiment includes a signal acquisition unit for receiving the feedback signal of the strip cleaning section; a signal analysis and processing unit for analyzing and processing the feedback signal and judging the feedback signal Whether there is a fault, if so, send the relevant information of the feedback signal, otherwise it will not be processed; the signal shielding button is used to eliminate the feedback signal of the strip cleaning section; the control unit is used to receive and analyze the relevant information of the received feedback signal, Start the corresponding signal shielding button.

[0035] It is worth noting that, in a...

Abstract

The invention provides a system and method for emergency processing of signals in the strip cleaning section. The system includes a signal acquisition unit, a signal analysis and processing unit, a signal shielding button and a control unit. After the signal acquisition unit receives the feedback signal, the signal analysis and processing unit It will judge the feedback signal and send out the relevant information of the feedback signal. The control unit will activate the corresponding signal shielding button to eliminate the feedback signal according to the corresponding relevant information. In the cleaning section, the abnormal feedback signal will cause the production line to stop, but the abnormal feedback signal is not Therefore, after eliminating the feedback signal, the continuous operation of the production line can be guaranteed, which has good practicability.

Description

technical field [0001] The invention belongs to the technical field of automatic control of cold-rolled strips, and in particular relates to an emergency treatment system and method for a strip cleaning section. Background technique [0002] In the continuous annealing strip production line, continuous production needs to be maintained, and there are many sensors for feedback signals in the strip cleaning section, so a lot of feedback signals will be fed back during the production process, and due to the high temperature and dust in the production environment Influence, each sensor is prone to malfunction. Once a certain sensor fails, not only will it not be able to detect normally, but the related feedback signal will also fail abnormally. What is more serious will cause the corresponding cleaning mode of the cleaning section to fail to start, which will affect the continuous annealing. The cleaning section of the strip steel production line cannot run, resulting in shutdow...
