In hazardous environments such as coal mines and metal mines where explosive gases such as gas and coal dust exist, any electric spark or overheating can cause disasters. Traditional communication and data collection devices cannot be used in such environments. The intrinsically safe handheld terminal for mining is an intelligent device designed specifically for such environments. It adopts an "intrinsic safety" design to ensure that the equipment is not capable of generating sparks or high temperatures that ignite explosive gases under normal operation and fault conditions. It has become a mobile safety pioneer in achieving digitalization and intelligence of mines.

Intrinsic safety is the core, intelligence is the soul. ​Mining intrinsically safe handheld terminalIt is not a simple reinforced version of an ordinary terminal. Its circuit and structure have been specially designed to limit the internal energy (electrical and thermal) to an absolutely safe level, thereby ensuring safety from an "essential" perspective.

1. Inherent safety, born for danger

The terminal strictly follows the mining explosion-proof standards, and all electrical parameters are precisely controlled within a safe range. Even if internal components experience faults such as short circuits or open circuits, the energy generated is far below the minimum energy required to ignite gas and coal dust mixtures, fundamentally eliminating ignition sources and ensuring the safety of underground personnel and facilities.

2. Durable and sturdy, fearless of harsh environments

In addition to explosion-proof, the terminal also has a high level of protection, which can effectively prevent the invasion of underground moisture, dust, and spray. Its body has been specially reinforced to withstand multiple drops and collisions, ensuring stable operation under harsh conditions such as vibration and impact, and high reliability.

3. Integrate multiple communications for real-time data exchange

The terminal integrates multiple communication modes such as Wi Fi, 4G/5G, Bluetooth, and mining explosion-proof wireless base stations. Staff can use it to communicate in real-time with the ground dispatch center for voice calls, video scheduling, personnel positioning, task reception and reporting, achieving seamless integration of information above and below the well, greatly improving production scheduling efficiency and safety management level.

4. Mobile applications empower on-site operations

Equipped with high-performance scanning heads, RFID and cameras, it can easily complete tasks such as equipment inspection, material inventory, hidden danger investigation, and data collection. All on-site data can be uploaded to the management system in real-time, digitizing the workflow and reducing errors in paper records and secondary inputs, achieving closed-loop management of the workflow.

The intrinsically safe handheld terminal for mining is a key entry point for the construction of smart mines. It integrates safety and intelligence, not only as a tool, but also as a core equipment for transforming traditional operation modes and improving the inherent safety level of mines. It is a trustworthy "smart partner" for miners underground.
