KT852 mine wireless communication system is an integrated communication system developed by our company for coal mine wireless communication system and specific environmental applications. The wireless access of this system adopts LTE wireless transmission technology, which is mature and stable, and the core network adopts soft switching technology, so the upgrade of subsequent products is smoother, the integration of networking is more flexible, and the investment value is effectively guaranteed. The main transmission network of the system adopts the mining intrinsically safe Ethernet, which effectively reduces the construction cost of the system and reduces the maintenance workload. The system has powerful fusion dispatching function, visual multimedia command dispatching system, visual multimedia conference system and high-definition video monitoring system The underground intrinsically safe substation of the system supports VoLTE high-definition voice and video calls, and is equipped with wifi 6 communication module, UWB precise positioning module, gigabit optical port, gigabit Ethernet electrical port and 100m optical port, which can be used in various scenarios.

Constant pressure liquid supply: PID algorithm controls variable frequency drive to ensure constant pressure liquid supply Automatic proportioning: precise control of oil proportion Balance wear: automatically switch the work and rest time of the equipment, and balance the wear of the main and standby equipment Reduce pipeline impact: the frequency converter starts smoothly, solves the impact of starting pipeline and prolongs the service life.

By adopting the TDLAS laser technology, the methane and the carbon monoxide gas can be simultaneously detected, the detection precision, the stability and the reliability are high, and is with IP65 protection, suitable for harsh environment, ultra-long standby, in line with mining intrinsic safety certification.

A sensing module that can perform long range non-contact detection of methane gas without specific reflective surface conditions, used for early warning and monitoring of scenarios such as sudden changes in gas concentration and pipeline leaks.

A non-contact handheld gas detection device that facilitates remote monitoring of methane component gas, suitable for hazardous gas warning products in multiple industries.

The product uses diffuse reflection monitoring technology without specific reflective devices. Based on the rotary pan-tilt design, it can realize methane monitoring in a circular area with a radius of 100 meters. It is suitable for monitoring scenarios with complex environments and concentrated valves and pipelines (e.g., station production areas). If the reflective device is set, it can achieve monitoring in the range of 200 meters. In addition, the product is equipped with a high-definition video camera, which can provide real-time video surveillance of the site area. Also, it can customize a variety of AI software algorithms based on video data, and intelligently analyze, record, and alarm abnormal images on the spot (such as the trespassing on the plant area, etc.).

A highly sensitive and accurate laser gas detection module applied to a -20-50 °C environment in the non-coal field.
