Dynamic correlation technology of wireless control device for hydraulic support
More Information
Abstract
In order to solve problem of safety operation of wireless control device for hydraulic support, working principle of the wireless control device for hydraulic support was analyzed, and a scheme of dynamic correlation of the wireless control device for hydraulic support was proposed based on infrared pyroelectric human body sensing technology. Human body sensing device for working face was developed to realize dynamic correlation of the wireless hand-held controller and hydraulic support driver, which improved operation safety of the wireless control device. Test results show that detection angle of the human body sensing device is 110°, detection distance is 10.6 m. In dynamic correlation action, communication connection delay time is about 1.1 s, and blocking action delay time is about 0.3 s, which can meet the requirements.
