Description

Mining intelligent type expanding and broadcasting rescue system

Technical Field

The invention relates to the field of broadcasting systems, in particular to an intelligent mining broadcasting rescue system.

Background

At present, underground communication and warning of coal mines generally use a mining voice signal device, a mining flameproof and intrinsically safe voice audible and visual alarm and a mining combined electric bell. These products are simple in function and generally only have a call and dotting function. The underground coal mine environment is bad, and operators work for a long time to be boring. There is also a significant disadvantage in that the coal mine is suddenly powered down and the equipment loses communication function. And the personnel in each roadway cannot be contacted when emergency is met.

The invention aims to overcome the defects of the prior art and provides an intelligent mining expanding and broadcasting rescue system.

In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:

an intelligent mining expanding and broadcasting rescue system is characterized in that: the system comprises a plurality of mining spread phones installed in each roadway in the pit, wherein the mining spread phones in each roadway are respectively connected through CAN buses, CAN-to-Ethernet modules are respectively arranged in the pit corresponding to each roadway, the CAN buses in each roadway are respectively connected with the corresponding CAN-to-Ethernet modules, the system further comprises a network switch, a control computer and an Ethernet-to-CAN module which are arranged on the pit, the CAN-to-Ethernet modules in each roadway are respectively connected with the network switch through Ethernet, the control computer is connected with the network switch through Ethernet, and the network switch is also connected with each CAN bus in the pit through the Ethernet-to-CAN modules.

The mining intelligent expanding and broadcasting rescue system is characterized in that: the mining broadcast telephone comprises a DVM series digital voice module, wherein a microphone input interface, an audio input interface, a direct current power supply interface and a button input interface are connected to the input of the DVM series digital voice module, a loudspeaker output interface and an acousto-optic indicator lamp interface are connected to the output of the DVM series digital voice module, and an SD/TF card interface, a liquid crystal display interface, an Ethernet interface, a CAN bus interface and an RS485 interface are connected to the DVM series digital voice module in a bidirectional mode.

The mining intelligent expanding and broadcasting rescue system is characterized in that: each mining broadcast telephone is respectively provided with a standby power supply formed by connecting a plurality of storage batteries in series.

In the invention, the operations of dotting, talking and music playing can be carried out on the well and under the well, such as global voice broadcasting and global dotting broadcasting can be carried out on the well; global voice communication and dotting are carried out in each roadway in the pit; and (5) dotting, shouting and the like in the underground roadway to the well.

In order to normally communicate after power failure, 8 sections of nickel-hydrogen batteries with the voltage of 1.2V/1500mAh are connected in series, and then 15 omega/25W current limiting resistors are connected in series and are encapsulated by epoxy resin to form an intrinsic safety battery assembly, wherein Ue is 9.6V; uo: 12.0V; io 0.84A.

The emergency escape system can be arranged at positions such as a roadway, a waiting room, a Hou Cheyun conveying line, a working face and the like, and when an emergency occurs, an emergency plan is automatically called, emergency broadcasting is carried out, and the emergency escape system can help miners to evacuate in an emergency and is used as an evacuation command tool. Music and public radio can also be listened to in a waiting room or a waiting room.
