Description

TECHNICAL FIELD

[0002] The coal mine hoisting equipment is used for lifting coal and gangue, lowering materials, lifting personnel and equipment. It is one of large-scale mining equipment and occupies a particularly important position in mine production. The movable drum and the fixed drum of the winding hoist are core components of the hoisting equipment, which are related to normal operation and safe operation of the coal mine hoisting equipment. The fixed drum is synchronous with the main shaft device, and the movable drum is also synchronous with the main shaft device. When the winding hoist needs to perform special operations such as rope adjustment, the movable drum is disconnected from the main shaft device through a rope adjustment clutch, and the two are not connected. When the special operation is completed, the movable drum is connected to the main shaft device through the rope adjustment clutch again, and the two are in a synchronous state. Under normal circumstances, the fixed drum and the movable drum are synchronous with the main shaft device. However, when a fault occurs or the rope adjustment clutch malfunctions during operation, the movable drum is disconnected from the main shaft device, and the movable drum is not controlled by the main shaft device. If the uncontrolled hoisting container driven by the movable drum is not found in time, it may cause equipment damage, injury or even death of personnel in the hoisting container, serious accidents such as damage of the hoisting device, death of personnel, and shutdown of the entire mine.

The specific analysis process is as follows: The operation indicator names are categorized. When the operation indicator belongs to category one, the first operation is performed on the operation indicator to obtain the first output result; when the operation indicator belongs to category two, the second operation is performed on the operation indicator to obtain the second output result. Perform execution control on the first and second output results; The specific process of the first operation is as follows: Obtain the threshold range corresponding to the operating indicator, and determine the corresponding indicator value with the threshold range: when the indicator value does not belong to the threshold range, generate a braking execution signal; When the indicator value falls within the threshold range, the corresponding partial threshold is obtained; the difference between the indicator value and the partial threshold is calculated to obtain the deviation value, and the acquisition time of the indicator value is marked as the deviation time; all deviation values ​​are analyzed to obtain the total deviation value; when the total deviation value is greater than deviation threshold one and less than or equal to deviation threshold two, deviation overshoot signal one is generated; when the total deviation value is greater than deviation threshold two and less than or equal to deviation threshold three, deviation overshoot signal two is generated; when the total deviation value is greater than deviation threshold three and less than or equal to deviation threshold four, deviation overshoot signal three is generated; the braking execution signal, deviation overshoot signal one, deviation overshoot signal two, and deviation overshoot signal three are marked as the first output result; The specific process for analyzing all deviation values ​​is as follows: Sort the deviation values ​​according to the order of their deviation times. Then, substitute the deviation values ​​and their times into the time difference line graph. Connect two adjacent deviation values ​​to obtain the deviation line. Select the midpoint of the deviation line and draw a circle with the midpoint as the center and one-quarter of the length of the deviation line as the radius. Draw a deviation triangle with the diameter of the circle as the hypotenuse of the triangle. Calculate the area of ​​the deviation triangle and extract the area value. Mark this value as the first deviation value. Determine the angle between the deviation line and the horizontal line. When the angle between the deviation line and the horizontal line is greater than 90 degrees, mark the first deviation value as the first deviation value. When the angle between the deviation line and the horizontal line is less than 90 degrees, the three deviation values ​​are marked as the second deviation value. All the first deviation values ​​are summed to obtain the first total deviation value; all the second deviation values ​​are summed to obtain the second total deviation value; the second total deviation value is divided by the first total deviation value to obtain the deviation ratio. Calculate the time difference between the deviation times corresponding to two adjacent deviation values ​​to obtain the deviation duration corresponding to the deviation line. Mark the deviation duration of the deviation line with an angle greater than 90 degrees to the horizontal line as the first duration, and mark the deviation duration of the deviation line with an angle less than 90 degrees to the horizontal line as the second duration. Summate all the first durations and all the second durations separately to obtain the total duration one and the total duration two. Divide the total duration two by the total duration one to obtain the deviation-time ratio. Extract the values ​​of the deviation ratio and the deviation-time ratio and process them to obtain the total deviation value.
