A dangerous attitude detection device and detection system for workers in a fully mechanized mining face

Abstract

The invention discloses a detection device and a detection system for the dangerous posture of workers in a fully mechanized mining face, belonging to the field of automatic control systems of fully mechanized mining equipment. The detection device includes a main controller, a wireless MESH transceiver, a depth sensor, an infrared transmitter, an infrared The camera, the Doppler frequency shift receiver, and the detection system include a hardware layer consisting of a detection device and a hydraulic support, and a human fusion positioning unit, an infrared image matching unit, a Doppler frequency shift analysis unit, and a human body dangerous posture recognition unit. Composed of software layers, the hardware layer and software layer communicate through the wireless MESH network. The present invention detects whether the current posture of the staff in the fully mechanized mining face is in a safe state and gives an alarm in a dangerous state, and prevents the occurrence of malignant accidents from the operating specifications of the staff; the present invention does not need to reform the fully mechanized mining face and does not require staff Wearing any auxiliary device, the posture of the worker can be detected.

Description

Technical field [0001] The invention relates to a posture recognition device and system, in particular to a dangerous posture detection device and a detection system for workers in a fully mechanized mining face, and belongs to the field of automatic control systems for fully mechanized mining equipment. Background technique [0002] Coal mining has always been a high-risk industry. Fully-mechanized mining automation and safe and efficient mining have always been key research issues. In particular, the national "863" and "973" plans have listed the safe and efficient mining of coal resources as key funding projects. Although the safety of coal mining has received widespread attention, the coal mining industry still has different levels of casualties every year. According to the National Coal Mine Safety Supervision Bureau, there were as many as 20 safety accidents in 2014 alone. Occurred, the death toll reached 101 people. [0003] However, as coal mining operations are becoming m...

AI Technical Summary

Problems solved by technology

[0003] However, as coal mining operations are becoming more and more automated today, the development of intelligent equipment for fully mechanized mining automation systems is in full swing, but there are very few studies on safety issues caused by irregular actions or operations of staff, let alone fully mechanized mining face work. Provide special detection devices or systems for personnel safety to prevent dangerous accidents
