Description

Mine-used I. S infrared network video camera

Technical field

The utility model belongs to mine monitoring equipment, is specifically related to a kind of Mine-used I. S infrared network video camera.

Background technology

At present, infrared network video camera aboveground be a kind of comparatively ripe product, the problem of monitoring on daytime can be solved well, but underground coal mine light is more weak does not even have light, the image that down-hole meets monitoring will be caught in real time and seem more difficult.

In addition, safety of China production monitoring supervisory control system is of a great variety, mostly the monitoring and controlling system used is the supervisory control system developed in the past the nineties, extensive employing centralized configuration and client/server (C/S) structure, centralized configuration can not meet the requirement of system dynamic change and expansion, although and C/S structure solves extended problem in certain limit, but still there is load and too concentrate on the problems such as server side.The Image Compression of current use is high to network bandwidth requirement, but underground coal mine network quality is poor, and Internet Transmission packet loss and the error rate are comparatively large, especially colliery industry subsurface environment inclement condition, insufficient light.

Utility model content

The utility model provides a kind of Mine-used I. S infrared network video camera, solves current safety production monitoring of coal mine grid transmission packet loss and the larger problem of the error rate, is especially applicable to the place of the particular/special requirement of underground coal mine dim light.

For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of Mine-used I. S infrared network video camera, comprises intrinsic safety casing and is arranged on main circuit, camera lens and the intrinsic safety electric source in described casing; Described main circuit is by infrared light board, and CCD, processing module, modular converter and cascade module form.When there is no light or dim light, described infrared light board is opened automatically, camera lens gathers light and sends in described CCD, after described CCD gathers light signal, by described processing module, optical signal prosessing is become vision signal, vision signal accesses described modular converter, and described modular converter is converted into network signal vision signal, be connected with computer by the RJ45 interface of described cascade module, computer is shown image by decoding software.Power to after externally fed is carried out intrinsic safety process by intrinsic safety electric source other each module above-mentioned.

Described infrared light board is made up of 30 LED light-emitting diodes.

Described cascade module is provided with multiple RJ45 interface.

Compared with prior art, the beneficial effects of the utility model are:

1, the video data exported can select compression bit rate and pressure texture according to actual conditions, and applicability is strong, saves Signal transmissions bandwidth.

2, cascade module possesses multiple subtending port, and the multiple video camera of energy cascade, reduces the labour intensity of line arrangement, save cable, also eliminate the horn mouth of down-hole switch.

3, little, lightweight, explosion-proof, the antidetonation of compact conformation, volume, utilizes snap joint constructability to safeguard.

Embodiment

As shown in Figure 1, described Mine-used I. S infrared network video camera comprises intrinsic safety casing and is arranged on main circuit, camera lens and the intrinsic safety electric source U6 in described casing, and described main circuit is by infrared light board U1, CCDU2, processing module U3, modular converter U4 and cascade module U5 form.Use the agreements such as embedded real-time operating system compatible TCP, UDP, DHCP, SNMP, HTTP, there is Remote WEB browsing management function, can remote monitoring be realized.Described main circuit is divided into three parts, and wherein Part I is the conversion of light signal and vision signal, and Part II is the conversion of vision signal and network signal, and Part III is network signal cascade.

As shown in Figure 2, Figure 3 and Figure 4, described video camera, under the control of U1, U2, U3, U4, realizes the collection of vision signal, conversion and output, by U5 and other video camera cascades.Wherein:

Described infrared light board U1 is made up of 30 LED light-emitting diodes, and when not having light or dim light, infrared lamp is opened automatically.

Described CCDU2 gathers light signal.

Described processing module U3 becomes vision signal optical signal prosessing.

Described modular converter U4 can be converted into network signal vision signal.

Described cascade module U5 adopts 3 RJ45 interfaces, the cascade between primary responsibility video camera and access transmission network.

As shown in Figure 5, the utility model is Mine-used I. S, thus equipment power will through intrinsic safety process; Use the circuit of two-stage LM723 and peripheral power tube composition, there is perseverance and stay source and export the function such as voltage stabilizing and overcurrent protection, prevent abnormal electrical power supply from producing spark damage circuit.

The course of work: when not having light or dim light, infrared light board U1 opens automatically, camera lens gathers light and sends in CCDU2, after CCDU2 becomes vision signal by processing module U3 optical signal prosessing after gathering light signal, vision signal access modular converter U4, through high performance dsp board and filtering, vision signal is converted to network signal by the process such as amplification, save Signal transmissions bandwidth greatly, RJ45 interface again through cascade module U5 is connected with computer, show on computers by decoding software, the video data exported can select compression bit rate and pressure texture according to actual conditions.Possess multiple subtending port, the labour intensity not only reducing line arrangement saves cable simultaneously, also eliminates the horn mouth of down-hole switch.
