Protection Functions
Photograph capture
Underground workers need to record the data or on-site pictures, can take photos through the information mine lights, the photos can be automatically transmitted to the ground, and the photos can be saved to the information mine lamp memory card, read the photos through the usb interface.
Dispatches can command mine lights to take photos automatically and transmit to the ground automatically.
Support early warning, alarm management function
The underground gas sensor and other kinds of sensor signals can be monitored, the early warning signal can be sent out in time, and the emergency warning signal can be received.
When the alarm is generated, the system provides acousto-optic display and alarm confirmation window.
The history warning and warning signals can be queried and printed according to the set conditions.
Support video surveillance real-time transmission
The video signal can be transmitted to the control center through 4g network through the information mine lamp, and the important area can be monitored in real time.
It can provide video signal setting interface to adjust the size, brightness and clarity of video interface.
The operator of the video surveillance system and their operating rights can be defined.
Information Survival Support
Information mine lights in the signal blind area voice and photos, after the signal recovery, can still be received, to ensure that the information is not lost.
Main Technical Parameters
Mining intrinsically safe informatization miner’s lamp is made up of lamp heads, cables and battery boxes. The lamp head is equipped with a main and auxiliary light source, which can be fixed on the safety helmet, and the irradiation angle is 120 degrees, which is larger than 80 degrees of the traditional mine lamp. The lamp head is equipped with intercom Mike and camera, press intercom health, can achieve intercom function.
The battery box is mainly composed of the lithium manganese acid ion battery, the rfid module 4g communication module, the key button, the mike, the horn, the camera and so on. the lithium battery is placed in separate cavities with other components, and the other components are powered by the lithium battery to consolidate the communication board control power supply.
There are four keys on the upper cover panel of the battery box of mine lamp. The four keys are: recording key, photo key and two standby keys, and the side panel consists of two keys, switch key and reset key respectively. Switch machine key is used to turn on and off communication card power, reset key can achieve fast shutdown.
The USB communication interface is used to implement USB wired communication with other electronics or PC machines in order to achieve data movement, storage and download upgrades for related programs.
Mike was protected. When he spoke, he opened the shield and then covered it.
Astigmatism and spotlight were applied to the camera’s camera to ensure that no white light appeared in the downhole。
The audio sound level intensity of the interphone shall be not less than 70 db at 1 m from the mine lamp.
Press the button on the lid of the battery box to hold the recording button. When you hear the sound of the “drop” to start recording, speak to Mike, the mine lights will be recorded, loosen the “recording” button to indicate the end of the recording, and after recording, send the information to the dispatch room through the 4G wireless base station.
Miner’s lamp are taken by hand and by receiving instructions.
Manual photography: long hold down the “photo” button, auxiliary lighting up, and then with the camera “click” sound to indicate that the photo is completed, the image automatically sent to the dispatch room through the 4G wireless base station.
accept the instructions to take photos: accept the dispatch room through the 4g wireless base station to send the photo instructions, auxiliary lighting, take photos, and automatically send the photos taken through the 4G wireless base station to the dispatch room.
