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...

The invention discloses a control method and device of a coal mine local ventilation automatic monitoring system and a processor. The method comprises the steps of receiving the gas content, the CO content and the CO2 content of a coal mine work face driving face; according to the gas content, the CO content and the CO2 content, calculating a first rotating speed of a local ventilator; receiving acurrent rotating speed, vibration information, a flow wind speed and temperature information of the local ventilator, and in combination with the current rotating speed, the vibration information, the flow wind speed and the temperature information, determining a correction rotating speed; and in combination with the first rotating speed and the correction rotating speed, determining a second rotating speed of the local ventilator. According to the gas content, the CO content and the CO2 content in the work face, in integration with the current rotating speed, the vibration information, the flow wind speed and the temperature information of a local ventilator body, the most-energy-saving highest-efficiency fan rotating speed can be calculated, monitoring of a fan incoming switch and a power total feed switch can be achieved, and after accidental power and wind failure, efficiency for recovering air supply and wind supply is quite high.
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...
