Abstract
The utility model discloses a mining intrinsic-safe-type infrared camera and relates to a mining monitoring and inspecting device. The mining intrinsic-safe-type infrared camera includes an intrinsic-safe-type power source module connected with an infrared lamp board, a CCD image sensor, a processing module and an optical fiber transceiver successively and supplying power for the above modules. When light in dim, the infrared lamp board is switched on automatically. A lens collects and sends light to the CCD image sensor. The CCD image sensor converts optical signals to video signals and sends the video signals to the processing module for processing. The processing module processes the video signals into RS485 signals and network signals. The network signals are connected to the optical transceiver. The optical transceiver is connected with a computer through an RJ45 and/or realizes long-range transmission through an optical fiber patch cord. The mining intrinsic-safe-type infrared camera provided by the utility model has an advantage that normal working can be realized in underground coal mine without light and a direct and reliable means is provided for safe production, regulation and decision making of a coal mine.
Description
Technical field
The utility model relates to mining monitoring equipment, it specifically is a kind of mine intrinsic safety type infrared video camera, be not only applicable to have under the coal mine environment of gas, coal dust explosion hazard, also be suitable for using in the industry ground adverse circumstances such as coal, metallurgy, chemical industry, building materials, traffic, electric power, grain, can directly include industrial Ethernet ring network system in.
Background technology
At present, it is of a great variety that China's downhole safety is produced monitoring and controlling system, and mostly the monitoring and controlling system of use is what developed the nineties in the past, and supervisory control system extensively adopts centralized configuration and C/S structure, can not satisfy the requirement of system's dynamic change and expansion, load too concentrates on the server.The present Image Compression of using is to the network bandwidth requirement height, but the coal mine lower network is of poor quality, and network transmission packet loss and the error rate are bigger.
Summary of the invention
The utility model provides a kind of mine intrinsic safety type infrared video camera, solve present Safety of Coal Mine Production supervisory control system network transmission packet loss and the big problem of the error rate, reduce the place that network transmits packet loss and the error rate and do not have light under coal mine, also can operate as normal.
The utility model is realized with following technical scheme: a kind of mine intrinsic safety type infrared video camera, comprise the housing that meets the coal mine downhole safety standard and be installed in the interior change-over circuit of housing, described change-over circuit comprises infrared lamp plate, ccd image sensor, processing module and the fiber optical transceiver that connects successively; Give the intrinsic safety electric source module of above-mentioned each module for power supply; Under the situation of dim light, infrared lamp plate is opened automatically, camera lens is gathered light and is sent in the ccd image sensor, ccd image sensor converts light signal to vision signal and sends into processing module and handle, processing module is treated as RS485 signal and network signal to vision signal, network signal is linked into fiber optical transceiver, and fiber optical transceiver directly links to each other or/and grow Distance Transmission by optical patchcord with computer through RJ45.
The beneficial effects of the utility model are:
1, video data has the requirement that high compression ratio satisfies storage and transmission, can select compression bit rate and pressure texture according to actual conditions, and applicability is strong, the saving hard drive space.
2, just can control the focal length of camera in the control room, regulate the quality of image.
3, little, in light weight, explosion-proof, the antidetonation of compact conformation, volume, protection against the tide are suitable for using under the coal mine, have good market prospects.
4, the place that does not have light under coal mine also can operate as normal, for Safety of Coal Mine Production, scheduling and decision-making commander provide directly perceived, means reliably.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.

Among the figure: U1, infrared lamp plate, U2, ccd image sensor, U3, processing module, U4, fiber optical transceiver, U5, intrinsic safety electric source module.
Embodiment
As shown in Figure 1, mine intrinsic safety type infrared video camera is by infrared lamp plate U1, ccd image sensor U2, and processing module U3, fiber optical transceiver U4 and intrinsic safety electric source module U5 form.Above-mentioned module is installed in the housing that meets the coal mine downhole safety standard, and housing is the seal casinghousing by metal or nonmetal preparation.Use agreements such as embedded real-time operating system compatible TCP, UDP, DHCP, SNMP, HTTP, have independently I/O interface, have remote web browsing management function.
As shown in Figures 2 and 3, video camera is at U2, and U3 under the control of U4, realizes collection of video signal, storage and transmission.Wherein: infrared lamp plate U1 is made up of 48 LED light-emitting diodes, and when low-light (level) (0 Lux), infrared lamp plate U1 opens automatically.
Ccd image sensor U2 can convert light signal to vision signal.
Processing module U3 becomes RS485 signal and network signal to Video processing.
Fiber optical transceiver U4 can change into light signal to network signal and grow Distance Transmission.
Intrinsic safety electric source module U5 adopts the AC-DC module, mainly is responsible for other each modules corresponding power supply is provided.
The course of work: under the situation of dim light, infrared lamp plate U1 opens automatically, and camera lens is gathered light and sent in the ccd image sensor U2, and ccd image sensor U2 converts light signal to vision signal, can directly be connected in display through the BNC head and show image.Processing module U3 is treated as RS485 signal and network signal to vision signal, network signal is linked into fiber optical transceiver U4, fiber optical transceiver U4 can directly link to each other with computer through RJ45, and the computer expert crosses decoding software image is shown, and also can grow Distance Transmission by optical patchcord.
