Automatic throttle control system and control method based on man-tramcar identification

Abstract

The invention provides an automatic throttle control system based on man-tramcar identification. A hydraulic air cylinder is installed below each throttle, a pressure sensing track is arranged below each throttle, and a laser sensor used for sensing tramcars and a temperature infrared detector used for sensing pedestrians are installed on the front and rear sides of each throttle respectively; when the sensor on the front side of each throttle senses that the tramcars or the pedestrians are about to pass through, the corresponding hydraulic air cylinder opens the throttle; when the sensor on the rear side of each throttle senses that the tramcars or the pedestrians pass through the throttle, the corresponding hydraulic air cylinder closes the throttle; logic OR linkage between the two throttles is designed, and when one throttle is opened, whether or not the other throttle stays in a closed state is determined at first. The invention also provides an automatic throttle control method based on the man-tramcar identification. The method includes the steps of using the laser sensors and pressure sensors for sensing the tramcars, using the temperature infrared detectors for sensing thepedestrians, opening the corresponding throttle when there are advancing objects in front of the throttle, and closing the corresponding throttle automatically after the advancing objects pass through the throttle. Not only can the tramcars be identified, but also men can be identified, the system and method are more intelligent, and the structure of the system is suitable for an underground workenvironment.

Description

technical field [0001] The invention relates to an underground damper control system, in particular to a damper control system which can be recognized by people and vehicles. Background technique [0002] The present invention applies the intelligent design theory to the design of the multi-system intelligent control system of the automatic damper, and designs different identification systems for the passing of the mining vehicles and people, distinguishes the mining vehicles and personnel, and analyzes the complex situations of personnel passing. Analyze and identify it, and take appropriate action. In addition, a fault diagnosis and alarm program is designed according to the system characteristics, which realizes the intelligentization of the control system at a lower cost and improves the operation reliability. [0003] Mine underground automatic dampers often need to take into account the passage of personnel and mine cars, and the operation situation is relatively comp...
