Abstract
The utility model discloses a gas meter detection system, which comprises a camera which is arranged in front of a plurality of gas meters, a video switch which is connected with each video signal output end and is used for combining and switching the inputted multiple videography information and for outputting the video information of number 1 to number 5 channel which need to be displayed, and an image analysis computer which is connected with the video signal output end of the video switch. When in use, quantitative air is charged into an air inlet of the gas meter, the camera is used for shooting numbers of the meter, the numbers are sent to the image analysis computer one by one through the video switch, the image analysis computer identifies and calculates the measurement precision of each gas meter, and finally the gas meter with the measuring error exceeding the setup range is listed and displayed and sent to a remote management computer.
Description
Technical field
The utility model relates to flow instrument standard detection field, relates in particular to a kind of gas meter detection system.
Background technology
Corresponding gas meter needs to detect one by one before dispatching from the factory, and guarantees the reliability of the coal gas meter reading that respectively dispatches from the factory.In the prior art, often adopt the method for manual detection, promptly the air intake at gas meter pours a certain amount of gas, and reading judges whether this gas meter is qualified according to gauge outfit then.The detection efficiency of this method is lower, wastes time and energy, and is unfavorable for saving human cost.How designing a kind of gas meter detection system that is suitable for batch detection, is the technical matters that this area will solve.
The utility model content
Technical problem to be solved in the utility model provide a kind of simple in structure, cost is lower and can carry out the gas meter detection system of batch detection to gas meter.
For solving the problems of the technologies described above, the utility model provides a kind of instrument in-line calibration device, comprising: be used to be arranged on a plurality of gas meters the place ahead video camera, link to each other with the VT of each be used for will input multichannel shooting information make up the video switcher of the 1-5 road video information output of switching and will need to show and the image analysis calculation machine that links to each other with the VT of video switcher.During use, quantitative air is charged into the air intake of gas meter, video camera is taken the numeral of gauge outfit then, send into the image analysis calculation machine one by one through video switcher, discern and calculate the measuring accuracy of each gas meter by the image analysis calculation machine, the gas meter that at last measuring error is exceeded setting range is listed and is shown, is sent to the telemanagement computing machine simultaneously.
Further, described image analysis calculation machine comprises the capure card that can catch 1-5 road vision signal simultaneously that links to each other with the VT of described video switcher.
Further, described image analysis calculation machine links to each other with the telemanagement computing machine, is used for remote monitoring.
Further, video camera had both left operating personnel's working position apart from the gauge outfit 0.8-1.2 rice of gas meter, had guaranteed clear picture again, and had made enlargement factor abundant.
The utlity model has following beneficial effect: gas meter detection system of the present utility model is by to the analysis of gas meter letter disk image, discern reading automatically, finish the automatic identification and the measuring accuracy that detect data by computing machine and calculate, reach the purpose that the full-automatic coal gas meter detects.This system can reduce staff's labour intensity, improves accuracy of reading, thereby finally raises labour productivity, and reduces operating cost.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail below, wherein:
Fig. 1 is the composition frame chart of gas meter detection system of the present utility model.
Embodiment
See Fig. 1, the gas meter detection system of present embodiment comprises: be used to be arranged on a plurality of gas meter a the place ahead video camera b, link to each other with the VT of each be used for will input multichannel shooting information make up the video switcher c of the 1-5 road video information output of switching and will need to show and the image analysis calculation machine d that links to each other with the VT of video switcher c.
Described image analysis calculation machine d comprises the capure card that can catch 1-5 road vision signal simultaneously that links to each other with the VT of described video switcher c.
Described image analysis calculation machine d links to each other with telemanagement computing machine e.
Video camera b had both left operating personnel's working position apart from the gauge outfit 0.8-1.2 rice of gas meter a, had guaranteed clear picture again, and had made enlargement factor abundant.
During use, quantitative air is charged into the air intake of gas meter a, video camera b takes the numeral of gauge outfit then, send into the image analysis calculation machine one by one through video switcher c, discern and calculate the measuring accuracy of each gas meter a by the image analysis calculation machine, the gas meter a that at last measuring error is exceeded setting range lists and shows, is sent to telemanagement computing machine e simultaneously.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
