Coal mine miners are generally regarded as high-risk occupations. Thanks to the improvement of mechanical automation and the development of technology, in fact, the mortality rate of coal mine accidents in China is close to that of developed countries. The widespread application ofCoal mine explosion-proof mobile phones is of great significance to the safety of mines. The mine explosion-proof mobile phone is anCoal mine intelligent terminal with MA certification. Through secondary development, it can assist in hidden trouble investigation and management, statistical analysis, hidden danger data reporting, and basic data synchronization. At the same time, it also has a downhole camera function, which can carry out on-site evidence collection of hidden dangers and "three violations", real-time entry of hidden dangers during the inspection process, and closed-loop management of hidden danger review. At the same time, after the base station is established in the well, one-click synchronization can be performed to communicate with the operating system of the PC client to achieve integration and information management of the well. In addition, in case of an emergency, the explosion-proof mobile phone matches the company's personnel positioning system, monitoring system and power supply system rubber, which can quickly lock the safety status of employees and the location of personnel. Conquer mobile phones with excellent quality and sturdy materials are widely used in emergency response industry. With the implementation of national leading safety production and emergency response implementation, there has been a huge market demand. As the leader of the three-proof custom brand, Conkasite launched Conquer the S8 explosion-proof version of the quality and safety explosion-proof mobile phones, which have passed harsh Class I and Class II explosion-proof certification, and are currently widely used in various industries; in order to meet the needs of customers, S8 accepts customized services from customers in various industries, whether it is small batch It can be flexibly matched even in large quantities.
