Abstract
The utility model relates to a video camera with a gas sensitive apparatus, which comprises a gas sensitive device and an ordinary video camera. The gas sensitive device consists of a gas sensitive element, a gas sensitive induction module, an induction control module and a buffer; the electrical connection is that: one output end of the gas sensitive induction module is connected with the input end of the buffer and the input end of the gas sensitive induction module is connected with the induction control module; the gas sensitive induction element is connected with the gas sensitive induction module in doubleaction; the input end of the central processor of the ordinary video camera is connected with the output end of the buffer, and one output end of the central processor is connected with the input end of the induction control module. The video camera can judge whether a poisonous or harmful gas exists in the photographing scene or not according to the change of electrical signal caused by that the poisonous or harmful gas chemically reacts with the gas sensitive device, and can be used for accurate judging and monitoring of severe environments that can not be distinguished or touched by manpower in industrial production and fire control monitoring, thus reducing the waste of capital and manpower.
Description
Technical field
The utility model relates to a kind of electronic monitoring device, particularly a kind of camera with gas sensitive devices.
Technical background
Along with product color digital camera and the monitor and the development of technologies of supervisory control system, the monitor series of products have entered market in large quantities, and various competitions with specific function watch-dog are very fierce.Along with development of times, market has proposed harsh more requirement to the function and the performance of security product.Safety monitoring with automatic monitoring poisonous and harmful substance function also arises at the historic moment with monitor.
Summary of the invention
Demand the utility model according to market provides a kind of gas sensitive devices and monitor to link together, and judges the camera that has gas sensitive devices whether pernicious gas exists.Concrete technical scheme is, a kind of camera with gas sensitive devices, comprise gas sensitive devices and common camera, it is characterized in that: gas sensitive devices is made up of gas sensitive device, air-sensitive induction module, induction control module, buffer, its circuit is connected to, one output of air-sensitive induction module links to each other with the input of buffer, an input links to each other with induction control module output, and gas sensitive device is connected with the air-sensitive induction module is two-way; The central processing unit input of described common camera links to each other with the output of buffer, central processing unit one output links to each other with the input of induction control module.
Its principle is, special poisonous and harmful substance gas and gas sensitive device device generation chemical reaction make the electrical functionality (resistance value capacitance etc.) of gas sensitive device device change, this change to make the signal of telecommunication that is transferred to the air-sensitive induction module change (variation of the variable effect signal of telecommunication of resistance value capacitance etc.), sensed back produces special signal and enters buffer, enter central processing unit by buffer memory, central processing unit reflects special warning picture in the corresponding picture after receiving corresponding change in electric on screen.Central processing unit is collected poisonous and harmful substance gas once more by air-sensitive induction module control gas sensitive devices again when reflecting special warning picture on screen, and contrast the existence that current information confirms to exist whether really poisonous and harmful substance gas, by central processing system this information is passed to the warning output interface and be reflected on the screen associated.
Characteristics of the present utility model are, what adopt is the gas sensitive devices that toxic and harmful uses, therefore be not subjected to the interference of poisonous and harmful substance, anti-people's interference or natural disturbance ability are strong, can be used in suitability for industrialized production and the fire fighting monitoring occasion, the zone that can't distinguish for manpower and the adverse circumstances that can't touch are measured accurately and are reported to the police.
