What are the functions of mine explosion-proof mobile phone

Explosion-proof mobile phones are the communication tools used by the mine staff in the mine. However, with the continuous improvement of the mine safety requirements, new requirements are also put forward for explosion-proof mobile phones.
At present, it is common to use 5G/4G network and underground WIFI to meet the needs of mine staff to conduct voice calls and video chat with the ground. What are the functions of mine explosion-proof mobile phones?

1、 Intercom function

1. Explosion-proof mobile phones in coal mines can realize uninterrupted voice call, two-way intercom, support shouting, and have functions such as one-button call for help, positioning, etc.

2. Mine explosion-proof mobile phones also support networking intercom. An explosion-proof mobile phone can be divided into multiple groups, and each group can set multiple call numbers (different incoming and outgoing calls can be set);
If there is a call between different groups, you can use the multicast function.

3. The mine explosion-proof mobile phone also has the function of multiple groups of calls: only one group of users are allowed to talk at the same time;
Each group of users can only call in or out once;
When the user's position changes, the system will automatically reestablish the call relationship of the group.

4. Explosion-proof mobile phones for mining use support hand-held and sub-controlled intercom, and also have a variety of voice coding methods and public address methods, with strong anti-interference ability.

2、 Voice communication function In the coal mine, it communicates with the ground through cables.
This requires the explosion-proof mobile phone to have the wireless voice transmission function, as well as the group call and call forwarding function, which can call and call forwarding through the ground voice broadcast.
In this way, coal mine accidents can be well avoided in the mine, and it can also ensure that the mine personnel can receive the instructions of the ground command center in time, so as to avoid being unable to be rescued in the first time in case of accidents.

3、 Video call function Video call is a communication means that must be used by underground workers when conducting underground command, dispatching and other important work.
Through video call, you can have a voice conversation with the commanders on the ground in the monitoring center, and see the pictures of the underground on the large screen. You can also locate the various points of the mine through mobile phone APP, and master the mine operation status in real time. Now, there are many explosion-proof mobile phones using 5G/4G network and underground WIFI on the market, which can meet the needs of voice calls and video chat between underground personnel and ground commanders.
However, such explosion-proof mobile phones need 5G/4G network and WIFI as support.
In addition, when using this kind of explosion-proof mobile phone, you need to wear a positioning device and a monitoring system to use it normally.

4、 Location service function The mine explosion-proof mobile phone can realize the accurate positioning of the coal mine operators, and with the positioning card worn by the upper and lower personnel, it can quickly and accurately provide real-time and dynamic location information for the coal mine operators.
Through the application of the communication function in the positioning card, the mine explosion-proof mobile phone can conduct real-time two-way transmission with the ground monitoring center.
Establish a reliable connection with the ground monitoring center through two-way positioning. At the same time, by reasonably setting the communication module installed in the positioning card worn by the underground personnel, the precise positioning of the underground personnel in different roadways and different operation locations can be realized;
When the explosion-proof mobile phone has a certain communication function, it can realize accurate and real-time two-way and multi-directional communication to underground operators.
Make mine explosion-proof mobile phone play a greater role in mine safety production. 5、 Emergency alarm function Due to the harsh underground environment, the staff will inevitably encounter some emergencies. At this time, there will be an emergency alarm button on the mine explosion-proof mobile phone. Users can report the situation to the ground monitoring center, the well management personnel, rescue personnel and leaders at the first time by pressing the button gently.

6、 Explosion-proof function In fact, the explosion-proof mobile phones used in coal mines are all waterproof, dust-proof and fall-proof mobile phones. Previously, they were usually used in coal mines. Explosion-proof mobile phones are basically upgraded from handheld terminals on the market. According to the explosion-proof transformation, the electric pool, flashlight, capacitor and other parts of handheld terminals are very easy to burn and even explode,
It prevents the ignition of flammable gas or smoke in flammable and explosive places when the parts are invalid.
