Abstract
Description
Technical Field
[0001] The invention relates to the technical field of steel production, and more particularly to a control method and system for a signal of a clamping device in a rear area of a double-high wire. Background Art
[0002] It is very important for the finished coil transport chain in the rear area of the double-high line of the rolling mill to hook normally, because if the hook is not hooked normally, it will directly lead to production interruption, which will lead to a decrease in output and an increase in the production cost per ton of steel. The existing fault is generally the signal failure of the clamping device in the rear area of the double-high line, which leads to the inability to hook in the entire area, which will lead to production interruption. First, the signal failure of the clamping device in the rear area of the double-high line will lead to the inability to hook in the entire area, which will lead to full coverage of the relevant fault analysis points. In this way, the troubleshooting of the fault points will be as many as 200 points, which requires a lot of time to troubleshoot, which will lead to a significant reduction in output and waste of related energy media consumption. Then, the signal failure of the clamping device in the rear area of the double-high line will lead to the inability to hook in the entire area. The entire processing process is all high-altitude operations, and the entire investigation area is very large, which will bring great safety risks to the entire troubleshooting process, and then increase the safety risks of personnel in related process positions and equipment maintenance positions. Finally, a signal failure at the clamping device in the rear area of the double-high line will cause the entire area to be unable to hook. Due to differences and uncertainties in the relevant order of troubleshooting, timing logic errors may cause chain damage during local trials, further leading to the expansion of the fault and an increase in spare parts costs.

[0006] When the real-time position of the clamping element is the open position, a first open position signal is output, and the open position signal of the clamp is collected at the same time, and the open position signal is compared with the first open position signal. When the open position signal is inconsistent with the first open position signal, an open fault signal is output and a second correction mechanism is triggered.
[0007] As a further improvement, when the clamping fault signal is received, a clamping failure alarm is issued.
[0008] Furthermore, the first correction mechanism is: replacing the clamping-in-place signal with a first clamping position signal, and performing a clamping-in-place operation on the clamper according to the first clamping position signal.

BRIEF DESCRIPTION OF THE DRAWINGS
[0022] Figure 1 This is a flow chart of the control method of the clamping device signal of the rear area workstation of the double high line of the present invention. DETAILED DESCRIPTION

Any limited number of modifications made by anyone within the scope of the claims of the present invention are still within the scope of the claims of the present invention.
[0024] See also Figure 1 The present invention provides a control method for a clamping device signal of a double-high-line rear zone workstation, the method comprising:
[0025] The real-time position of the clamping element of the clamp is obtained to achieve accurate quantification of the position of the clamping element.
[0026] When the real-time position of the clamping element is the clamping position, the first clamping position signal is output, and the clamping position signal of the clamp is collected at the same time, and the clamping position signal is compared with the first clamping position signal. When the clamping position signal is inconsistent with the first clamping position signal, a clamping fault signal is output and the first correction mechanism is triggered, so as to realize the control and efficient diagnosis of the clamping position signal.
[0027] When a clamping fault signal is received, a clamping fault alarm is issued to quickly remind the user of the clamping fault signal.
[0028] The first correction mechanism is: replacing the clamping in place signal with the first clamping position signal, and performing a clamping in place operation on the clamper according to the first clamping position signal, thereby achieving replacement and optimization of the clamping in place signal.
[0029] When the real-time position of the clamping element is the fully opened position, the first open position signal is output, and the fully opened signal of the clamp is collected at the same time, and the fully opened signal is compared with the first open position signal. When the fully opened signal is inconsistent with the first open position signal, an open fault signal is output and the second correction mechanism is triggered, so as to realize the control and efficient diagnosis of the fully opened signal.
[0030] When an opening fault signal is received, an opening fault alarm is issued to realize a quick reminder of the opening fault signal failure.
[0031] The second correction mechanism is to replace the fully opened signal with the first open position signal, and perform fully opened operation on the clamp according to the first open position signal.
[0032] The working status of the power supply of the clamp is obtained through the visualized conversion output, and the working status of the power supply of the clamp can be displayed on the central control screen. When the working status of the power supply of the clamp displayed on the central control screen is a fault state, the clamp is shut down to obtain the power supply fault state and handle the fault, thereby reducing the risk of damage to the clamp due to power supply.
[0033] A control system for a clamping device signal at a rear workstation of a double-high line, the system comprising:
[0034] The first proximity switch is installed at the fully opened position of the clamp and is used to output a fully opened signal when the clamping element approaches the fully opened position.
[0035] The second proximity switch is installed at the clamping position of the clamp and is used to output a clamping signal when the clamping element approaches the clamping position.
[0036] The position sensor is installed on the clamping element and is used to obtain the real-time position of the clamping element and output the real-time position signal of the clamping element.
[0037] The controller is used to receive the opening position signal, the clamping position signal and the real-time position signal of the clamping element.
[0038] The controller performs opening and clamping operations on the clamp according to the above-mentioned control method for the clamp signal of the rear area workstation of the double-high line through the opening position signal, the clamping position signal and the real-time position signal of the clamping element.
[0039] The system realizes efficient control over the opening and clamping of the clamps at the winding station, and implements emergency operations for the clamping signal failure state and the opening signal failure state, thus avoiding the situation where the entire area cannot release the hook due to the clamping signal failure, and improving work efficiency.
[0040] The above is only a preferred embodiment of the present invention.
