AI Technical Summary

Problems solved by technology

During the operation of the fan, if the damper fails to close, it will cause a "surge" failure of the fan, which will affect the ventilation of the mine and seriously damage the fan; at the same time, there is a risk that the blade angle of the fan with adjustable blades will suddenly return to zero. Cause the mine to stop wind for a long time, down to the occurrence of serious safety accidents

Embodiment 1

[0024] like figure 1 As shown in the figure, a safe operation method of a mine main ventilator includes the following steps:

[0025] S100. It is detected that the fan blade actuator receives the blade zeroing instruction;

[0026] S200, judging the trigger condition of the blade zeroing instruction to determine whether to start the alarm program;

[0027] S300, according to whether the alarm program is started, determine whether to start the monitoring of the blade position of the main fan of the mine.

[0028] Specifically, after monitoring that the fan blade actuator receives the blade zeroing instruction, it judges the triggering condition of the blade zeroing instruction, and when it is judged that the triggering condition of the blade zeroing instruction is inconsistent with the preset normal blade zeroing condition, an alarm program is triggered , start the mine main fan blade position monitoring and send the video signal captured by the monitoring to the designated v...

Embodiment 2

[0037] like figure 2 As shown, a mine main ventilator safe operation system includes:

[0038] The monitoring module 100 is used for monitoring the fan blade actuator receiving the blade zeroing instruction;

[0039] The judgment module 200 is used for judging the trigger condition of the blade zeroing instruction;

[0040]The processing module 300 is used for triggering an alarm program according to the judgment result of the judgment module, starting the monitoring of the blade position of the mine main fan, and sending the video signal captured by the monitoring to the designated video receiving terminal.

[0041] Specifically, after monitoring that the fan blade actuator receives the blade zeroing instruction, it judges the triggering condition of the blade zeroing instruction, and when it is judged that the triggering condition of the blade zeroing instruction is inconsistent with the preset normal blade zeroing condition, an alarm program is triggered , start the mine...

Embodiment 3

[0050] An electronic device, comprising at least one processor; and a memory connected in communication with the at least one processor; wherein the memory stores a program of instructions executable by the at least one processor, and the program of instructions is executed by the at least one processor to cause at least one A processor can implement the mine main fan safe operation method as listed in Example 1.

[0051] Further, the instruction program includes the safe operation system of the mine main ventilator as listed in Embodiment 2.

Abstract

The invention discloses a method, system and equipment for the safe operation of a mine main fan, comprising: after monitoring that a fan blade actuator receives a blade zeroing instruction, judging the triggering condition of the blade zeroing instruction; When the condition is inconsistent with the preset normal zeroing condition of the blade, the alarm program is triggered to start the monitoring of the blade position of the mine main fan and send the video signal captured by the monitoring to the designated video receiving terminal. Increase the blade zeroing command trigger condition judgment and video monitoring. When the blade returns to zero abnormally, an alarm will be issued to remind the site personnel to restore the blade angle in time to ensure normal mine ventilation, and avoid when the power supply of the control system is powered off or the blade actuator is in manual automatic mode. When switching, no one finds in time, the mine will be in a windless state for a long time, causing huge safety production accidents in the mine, which effectively makes up for the lack of protection in the control system and ensures the safe and stable operation of the mine main fan.

Description

technical field [0001] The invention belongs to the technical field of coal mine production equipment control, and in particular relates to a safe operation method, system and equipment of a mine main ventilator. Background technique [0002] At present, the main fans of coal mines mostly use axial fans with adjustable moving blades. Generally, each air shaft is equipped with two fans, one for normal operation and one for backup to ensure the safety of air supply in the mine. During the operation of the fan, if the damper fails to close, it will cause a "surge" failure of the fan, which will affect the ventilation of the mine and seriously damage the fan. At the same time, the adjustable moving blade fan has the risk of the blade angle suddenly returning to zero. If no one finds out in time, it will It caused the mine to stop the wind for a long time, which led to the occurrence of serious safety accidents. [0003] Therefore, the existing technology still needs to be furth...
