Unique Wellhead Attendance Management System
The unique wellhead attendance management system is used for attendance management of underground personnel, integrating the iris/face biometric identification, RF identification, computer and other techniques. It is mainly composed of the system software, monitoring host, biological attendance management base station, iris/face recognition device, exciter, gate and the like. Its core function is to prevent underground personnel from carrying no card or carrying faulty cards, incorrect cards or excess cards. In addition, the system can be expanded for alcohol detection, body temperature detection, and helmet detection.
KJ641 Mine Vehicle Management System
The KJ641 mine vehicle management system is an intelligent dispatching management system integrating vehicle positioning, attendance management, speed measurement, voice call, driving video monitoring, traffic light control, dispatching and parking, “Didi taxi”, etc., to prevent the access of illegal vehicles, reduce violations of underground driving and improve transportation and dispatching capabilities. It can also further improve the underground personnel and vehicle safety as well as the vehicle operation efficiency, and provide a technical guarantee for energy saving, energy consumption reduction, efficiency improvement, cost decrease, and scientific dispatching.
Equipment Lifecycle Management System
The equipment lifecycle management system based on ZigBee positioning technology is mainly used for mining equipment management within the whole lifecycle from procurement, storage, distribution, use and maintenance to scrapping.
Equipment Health Management and Intelligent Analysis System
The equipment health management and intelligent analysis system based on the sensing technology, wireless transmission technology, computer technology and other technologies is used for online operation monitoring, analysis, warning and alarm of equipment within the whole lifecycle, by collecting the vibration and temperature parameters of rotating equipment, thereby ensuring the stable and healthy operation of equipment.
KT661 Wireless Communication System (5G)
The KT661 (5G) wireless communication system for mines is mainly composed of the three-layer 10G switches, station controllers (BBU), multimedia edge gateways, integrated service switches, dispatching servers, recording servers, and 5G core network.
KT552 Wireless Communication System (4G) for Mine
The KT552 wireless dispatching communication system for mines is designed to improve the production dispatching level and safety of coal mines. It can be used to integrate and transmit high-speed data to support the construction of an advanced, stable and reliable system platform for intelligent digital mines.
KT403 Wireless Communication System (WiFi) for Mine
The KT403 wireless communication system for mines is a new-generation internal communication system, with the standard SIP protocol as the core, integrating the advanced call control, audio processing, QoS guarantee and other technologies. The system is mainly composed of the underground AP, integrated business management platform, voice gateway, ground WIFI base station, AC controller, touch screen dispatcher, WiFi mobile phone, etc.
KT670Broadcast Communication System for Mine
The KT670 broadcast communication system for mines is, based on the VoIP technology and standard SIP protocol, used for underground emergency broadcasts and voice calls. It is mainly composed of the broadcast system software and server, broadcast substation, etc. Main functions of the system include the triggered broadcast, instant broadcast, scheduled broadcast, voice broadcast, music broadcast, text broadcast and record broadcast. This system supports multicast and unicast modes. Due to the built-in dynamic multicast technology, the system supports the broadcast priority. In addition to broadcasts, the system also supports IP calls for voice communication between the broadcast substations as well as between the broadcast substation and dispatching center.
KJ1416 Mine Water Level and Flow Monitoring System
With the 24GHz millimeter radar wave as the carrier signal, the intelligent monitoring system can be used for non-contact real-time measurement of water levels of mine sumps, roadways, surface rivers, open channels, reservoirs, sewage pipeline networks, flood control and warning, etc.
