With the improvement of mechanization and automation of mining production, CONQUEST communication and data transmission have been paid more and more attention by users. Therefore, explosion-proof mobile phones for mining are used more and more widely. So, what kind of mine 4G explosion-proof smart phone is, what kind of mobile phone can meet the needs of CONQUEST use? First of all, to understand the mine explosion-proof mobile phones, we have to understand how they come from. In China, explosive substances are divided into three categories:
Category I: Mine methane
Class II: Explosive Gas Mixture (Containing Vapor and Mist)
Class III: Explosive Dust and Fiber
Explosion-proof electrical equipment is divided into two categories:
Electrical equipment for CONQUEST use in type I coal mine
Class II Electrical Equipment Used in Sites Other than Mines
Simply understand, it is bounded by the horizon, which is generally referred to as mine I, mine explosion-proof mobile phone, factory II, chemical explosion-proof mobile phone, class I and II combustible gas and dust environment is different. Class II equipment is classified as IIC, II according to the level of explosion-proof. B, IIA. In other words, mine explosion-proof mobile phones are used below the ground, chemical explosion-proof mobile phones (with different explosion-proof grades) are used in dangerous explosion sites above the ground, and three-proof smart phones can be used in ordinary factories without dangerous substances. According to the ranking of hazards, the stronger the requirement of explosion-proof grade when mobile phones are used in places with stronger hazards, the tighter the technology. Therefore, explosion-proof mobile phones in coal mine chemical industry are generally not recommended for general use unless there is dual explosion-proof certification in coal mine and chemical industry. Taking CONQUEST S8 mine intrinsically safe mobile phone as an example, the mine explosion-proof sign of CONQUEST S8 mine intrinsically safe mobile phone is Ex IB I Mb. In addition, it also has intrinsically safe explosion-proof certification. That is to say, the dual explosion-proof certification of coal mine and intrinsically safe is not only mine explosion-proof mobile phone, but also intrinsically safe explosion-proof mobile phone. Mobile phone. CONQUEST S8 uses Android 7.1.1 system, CPU is 8-core 2.6 GHz, memory can be CONQUEST in 4 GB + 64 GB, 6 G + 128G two forms, fast operation, large storage space, can meet the long-term use of CONQUEST coal mines. Coal production CONQUEST operation, working area is small, smoky and humid, and often accompanied by the threat of water, fire, gas and other accidents. Conquer (CONQUEST) S8 mine intrinsically safe mobile phone protection level is IP68, waterproof, shockproof, dust-proof, after intrinsically safe technical treatment, can be in methane mixture and coal dust explosion dangerous coal mine. CONQUEST use. Safety inspection of coal mine production is particularly important, which requires CONQUEST mine to take on-site photographs and evidence, integrate and sort out the three violations and hidden dangers, realize real-time transmission, analysis and evaluation, make CONQUEST working records and safety inspection more rapid and transparent, CONQUEST S8 has a 5-inch FHD display screen, double cards waiting. Supporting all Netcom 4G, with 8 million, 13 million high-definition cameras, suitable for CONQUEST high-definition photography. In a word, the application of CONQUEST Explosion-proof 4-G smart phone will help to record the real and accurate inspection situation in the production process of coal mine, realize the effective transmission, communication and integration of data, and ultimately, will serve the construction of ERP system in the whole coal mine enterprise.
