Description
Technical field
The utility model relates to detecting instrument, is specifically related to the colliery pipeline and uses carbon monoxide transducer.
Background technology
Carbon monoxide is a kind of odorless, colourless, tasteless toxic gas.Content Law Control to carbon monoxide in the air puts teeth in, and particularly the control of the carbon monoxide content of getting working face, return aircourse, dynamo-electric cavern is particularly important to the safety in production that guarantees the colliery under the coal mine.Existing carbon monoxide transducer is made up of sample circuit, amplifying circuit, temperature-compensation circuit, analog to digital conversion circuit and displaying alarm.The sample circuit and the gas concentration that adopt are nonlinear relationship, cause measuring accuracy low; The temperature drift of probe is big, and the continuous working continuation is poor.
The utility model content
The utility model technical matters to be solved is to provide a kind of highly sensitive, stable performance, and the colliery pipeline of long service life is used carbon monoxide transducer.
The utility model technical matters to be solved adopts following technical scheme to realize,
The colliery pipeline is used carbon monoxide transducer; Comprise housing; Said housing front is provided with display screen, and said housing bottom is provided with aviation plug A and aviation plug B, and said aviation plug A is connected with sensing head on the piping system; Said aviation plug B is connected with an extraneous associate device, and said enclosure interior is provided with the data processing unit that links to each other with display screen.
Said data processing unit comprises central processing unit, and said central processing unit is made up of single-chip microcomputer and A/D converter, and said central processing unit is connected with sensing head, power supply, display, alarm and signal output apparatus through distinct interface respectively.
The beneficial effect of the utility model is: 1, adopt import high-precision sensing original paper, and long service life, moistureproof dustproof anticorrosive erosion, instrument performance is more stable;
2, adopt new single chip microcomputer and high integrated digital circuit, make circuit structure simple, dependable performance is convenient to maintenance and debugging;

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Like Fig. 1, shown in Figure 2; The colliery pipeline is used carbon monoxide transducer, comprises housing 1, and said housing 1 front is provided with display screen 2; Said housing bottom is provided with aviation plug A4 and aviation plug B5; Said aviation plug A4 is connected with sensing head 3 on the piping system 7, and said aviation plug B5 is connected with an extraneous associate device, and said housing 1 inside is provided with the data processing unit 6 that links to each other with display screen 2.After sensing head 3 detects carbonomonoxide concentration; Through aviation plug 4 signal of gathering is transferred to data processing unit 6; Data processing unit 6 is handled the signal that collects on the spot; On display screen 2, show, through aviation plug 5 data transmission is arrived associate device then, carry out remote monitoring.
Said data processing unit comprises central processing unit, and said central processing unit is made up of single-chip microcomputer and A/D converter, and said central processing unit is connected with sensing head, power supply, display, alarm and signal output apparatus through distinct interface respectively.
After the sensing head of the utility model detects carbonomonoxide concentration; Concentration signal is passed to central processing unit; A/D converter in the central processing unit becomes digital signal transfers to give single-chip microcomputer analog signal conversion on one side; Single-chip microcomputer shows the signal that collects after treatment on display, during numeral value of being above standard of showing on the display, alarm will give the alarm; Do not surpass higher limit if show numerical value, single-chip microcomputer is transferred to associate device with concentration signal through signal output apparatus again, realizes remote centralized control.The effect of power supply is to be the utility model power supply, accomplishes the pacing items of said process.
More than show and described ultimate principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
