Embodiment Construction

[0012] The content of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] 1. The overall framework of the system

[0014] like figure 1 As shown, a ventilation fan air divider closure detection system, the system includes: monitoring layer, control layer, implementation layer, detection layer.

[0015] The detection layer includes a gas sensor, a carbon dioxide sensor, an air volume sensor, a wind speed sensor, an infrared camera, and a rotary encoder to collect gas content, carbon dioxide content, air volume, and wind speed of the excavation face in real time, to identify personnel, and to detect the gas content in the closure adjustment device. The telescopic distance of the telescopic rod, and transmit the relevant information to the PLC controller of the control layer, to realize the online monitoring of the wattage content, carbon dioxide content, air volume, wind speed, explosive consumption, and the number of ...

Abstract

The invention relates to a method for detecting the closure degree of an air distributor of a ventilator, and the method comprises the steps: installing a closure degree adjustment device in the air distributor through the structural design and layout mode of the air distributor, analyzing the characteristics of different layouts of baffles, adjusting the closure degree of the air distributor through the device, and detecting the number of rotation turns of a shaft through a rotary encoder, calculating the closure degree of the air distributor through a displacement-closure degree mathematical model, controlling a single brushless direct current motor through cascade PID, achieving position synchronization between the two motors through a cross coupling control algorithm, and making the closure degree of the air distributor to be within the required error range, and achieving automatic detection and control of the closing degree of the air distributor through the closing degree adjusting device.

Description

technical field [0001] The invention relates to the ventilation field of an underground ventilator used in mines, in particular to a method for detecting the closure degree of an air divider of a ventilator. Background technique [0002] Gas is an inevitable harmful gas in the process of coal mine production. In addition, mine coal dust and dust also affect the safety of mine production. Conventional ventilation management systems generally rely on manual operation and control by relevant personnel, which can easily cause safety management loopholes and safety production accidents. Therefore, the intelligence and visualization of the ventilation management system can greatly improve the reliability of the ventilation safety management system, and can minimize the probability of safety production accidents and the consumption of safety management costs. The automatic switching of the air distributor of the local ventilator, the air supply on demand and the flexible adjustmen...
