Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The embodiment of the invention discloses a control method for automatic monitoring system of coal mine local ventilation, such as figure 1 As shown, it specifically includes the following steps:

[0036] Step 102: Receive the gas content, CO content and CO content at the front of the coal mine face 2 content.

[0037] In this embodiment, the gas content, CO content and CO 2 The content is compared with the set value, when the gas content, CO content and CO 2 When the content is less than or equal to the set value, the start-up of the local fan is blocked to realize energy saving of the system.

[0038] In this embodiment, it is also possible to receive the gas content within the operating range of the local ventilator; compare the gas content within the operating range of the local ventilator with the size of the set value; when t...

Abstract

The invention discloses a control method, device and processor of a coal mine local ventilation automatic monitoring system, which can receive the gas content, CO content and CO 2 content; according to gas content, CO content and CO 2 The content calculates the first speed of the local fan; receives the current speed, vibration information, flow wind speed and temperature information of the local fan, and combines the current speed, vibration information, flow wind speed and temperature information to determine the corrected speed; combines the first speed and Correct the speed to determine the second speed of the local fan. The present invention can be based on the gas content, CO content and CO content in the working face 2 content, and collect the current speed, vibration information, flow wind speed and temperature information of the local fan itself, calculate the most energy-saving and efficient fan speed, and realize the monitoring of the fan inlet switch and the main power feed switch, in the event of an unexpected power failure The efficiency is very high when the power supply and air supply are resumed after the wind is stopped.

Description

【Technical field】 [0001] The invention belongs to the technical field of coal mine ventilation, and in particular relates to a control method, device and processor of an automatic monitoring system for coal mine local ventilation. 【Background technique】 [0002] Coal mine local ventilation refers to the ventilation of the tunneling face. When mining underground shafts, in order to supply fresh air, dilute and remove smoke, dust and harmful gases from the tunneling face, and create a good working environment, general wind twist ventilation, Local ventilation methods such as diffusion ventilation, ejector and local fan ventilation. [0003] The existing local fan ventilation method uses local fan frequency conversion speed regulation technology, downhole gas sensor measurement technology, electrical monitoring PLC technology and upper computer configuration software monitoring technology, and communicates with the dual fan dual power switch through the local fan monitoring PLC...
