2. adopt digital optical signal output, can be by star-like, bus-type or the transmission of belt Ethernet, long transmission distance, dispose convenient, the video camera that has solved analog optical signal output needs past point-to-pointly aboveground laying optical cable, has the problem that networking model is single, quantities is big, networking cost is high.Adopt the output of WLAN wireless ethernet, can realize wireless transmission, solved the problem of wiring by wireless ethernet.
3. the digital video monitor system of being made up of web camera is simple in structure, assembly is few, has solved the too much problem of mining analog video supervisory control system assembly.
4. the big capacity storage of digital signal, inquiry simply, have conveniently solved the problem of mining analog video supervisory control system storing queries difficulty.
5. the backup battery of web camera has solved the problem in mining analog video supervisory control system power backup without issue pond.
6. web camera is to the support of Simple Network Management Protocol, and having solved mining analog video supervisory control system can't telemanagement, the problem of configuration.
For solving the problems of the technologies described above, the utility model is realized by the following technical solutions:
Network camera for mining is made up of camera lens, image-forming module, coding and control module, Ethernet transport module, flameproof enclosure, power module, described camera lens connects image-forming module, image-forming module connects coding and control module, coding is connected the Ethernet transport module with control module, above-mentioned module is installed in the flameproof enclosure, forms network camera for mining.
Described web camera, power module is the Uninterruptible Power Module of band backup battery, system can operate as normal in the power failure or the environment that temporarily cuts off the power supply.
Described web camera, ethernet module can be selected optical fiber transceiver module or WLAN wireless ethernet module.
Described web camera is equipped with infrared lamp in the flameproof enclosure.
Described web camera, the image-forming module that uses be that coloured silk changes black module.
Described web camera is supported measured simple network management snmp protocol.
Described web camera uses the Hi3510 chip as the communication medium processor chips.
The utility model has the advantages that:
1. network camera for mining output is Ethernet digital optical signal or WLAN wireless ethernet signal, and transmission group net is simple, long transmission distance, picture quality is good, reliability is high, cost is low;
2. storage, demonstration, inquiry, easy maintenance.
3. have backup battery, still can work under the power failure that temporary interruption, urgent disaster cause.
4. have remote browse, management, maintenance, configuration feature.
5. satisfy explosive gas atmosphere electrical installation requirement under the coal mine.
