Abstract
Disclosed is an intrinsic safety type anti-explosion three-channel communication base station. The intrinsic safety type anti-explosion three-channel communication base station comprises a fiber interface, a cable interface and a wireless receiving antenna, optical signals or electrical signals received by the fiber interface, the cable interface and the wireless receiving antenna are transmitted to a receiving unit, the receiving unit is connected with a communicating unit, the communicating unit sends processed optical signals or electrical signals to a retransmission module, and the retransmission module is connected with an optical antenna and a radio antenna. By means of the technical scheme, an optical interface and a wireless interface are added on the basis of a prior communication base station, and namely, the communication base station comprises the cable interface, the fiber interface and the wireless interface. Accordingly, when the cable interface can not be used due to the fact that the underground environment is bad, the cable interface can be directly switched to the fiber interface to work, a wireless mode can also be used for communication, thereby continuous and normal usage of the underground communication base station can be guaranteed, and the underground work efficiency is improved.
Description
Technical field
The utility model relates to a kind of communication base station.
Background technology
Existing communication base station only has a cable interface usually.When this communication base station is applied in coal mine lower time, because environment is abominable, situation about rupturing often appears in cable, causes communication base station normally to use, and has brought great inconvenience for the exploitation work of down-hole.
Summary of the invention
The purpose of this utility model is to provide a kind of intrinsic safety type anti-explosion three-way road communication base station that comprises cable interface, optical interface and wave point, guarantees the normal use of underground communica tion base station.
For achieving the above object, the utility model is by the following technical solutions:
A kind of intrinsic safety type anti-explosion three-way road communication base station, it comprises optical fiber interface, cable interface and wireless receiving antenna, described optical fiber interface, cable interface and wireless receiving antenna are sent to receiving element with light signal or the signal of telecommunication that receives, and receiving element is connected with communication unit; Light signal or the signal of telecommunication after communication unit will be processed are sent into retransmit module, and retransmit module connects optical antenna and wireless aerial.
Described communication unit comprises band pass filter I, low noise amplifier, mixting circuit, band pass filter II, amplifier, A/D modular converter, digital down converter and the baseband processor that connects successively.
Adopt the utility model of technique scheme, increased optical interface and wave point on the basis of original communication base station, namely communication base station of the present utility model had both comprised cable interface, comprised again optical fiber interface and wave point.Like this, when subsurface environment badly causes cable interface to use, can be directly switch into optical fiber interface work, also can adopt wireless mode communication to use, thereby guarantee normal use the continuously of underground communica tion base station, improve underground work efficient.
Description of drawings
Fig. 1 is theory diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of dual-channels communication base station, it comprises optical fiber interface 1, cable interface 2 and wireless receiving antenna 8, above-mentioned optical fiber interface 1, cable interface 2 and wireless receiving antenna 8 are sent to receiving element 3 with light signal or the signal of telecommunication that receives respectively, and receiving element 3 is connected with communication unit 4; Light signal or the signal of telecommunication after communication unit 4 will be processed are sent into retransmit module 5, and retransmit module 5 connects optical antenna 6 and wireless aerial 7.
Operation principle of the present utility model is: the state of the real-time detection fiber interface 1 of receiving element 3, cable interface 2 and wireless receiving antenna 8.When the cable disconnection, when cable interface 2 can not use, receiving element 3 switched to the signal that receives the light signal that optical fiber interface 1 transmits; Light signal is sent into communication unit 4 by after the processing of receiving element 3, and last light signal sends by retransmit module 5 and optical antenna 6.
When cable interface 2, optical fiber interface 1 and wireless receiving antenna 8 can normally use, system default was preferentially selected cable interface 2.
