Description
Technical Field
The utility model relates to a calibrating device, especially a carbon dioxide incubator calibrating device.
Background
The carbon dioxide incubator is an instrument for culturing tissues, cells and bacteria. It is an important device essential for scientific research. To ensure that the experimental data and experimental results are accurate, the CO must be measured and calibrated frequently2The concentration in the incubator is ensured to be consistent with the set concentration. The current calibration device generally only has one carbon dioxide detector, and has slow calibration and insufficient accuracy.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims to solve the technical problem that to prior art not enough, provide a carbon dioxide incubator calibrating device.
In order to solve the technical problem, the utility model provides a carbon dioxide incubator calibrating device, including four telescopic links, contained angle between the two adjacent telescopic links is 90 degrees, four telescopic links form the base, and the central point of base puts the department and is equipped with the middle part lifter, and the tip of four telescopic links corresponds respectively and is equipped with a tip lifter, corresponds respectively on middle part lifter and the tip lifter and is equipped with a couple, and the correspondence is equipped with a carbon dioxide detector on every couple.
The utility model discloses in, the carbon dioxide detector is infrared carbon dioxide detector.
The utility model discloses in, all be equipped with the scale on middle part lifter and the tip lifter.
The utility model discloses in, the carbon dioxide detector passes through AD converter electric connection to CPU, and CPU receives the RS485 signal that comes from the carbon dioxide detector to convert serial ports signal and upload to CO2Gas concentration display for displaying CO2The real-time concentration of the gas.
In the utility model, CO2The gas concentration display is powered by 24VDC, which is converted to 5VDC power for the CPU and carbon dioxide detector.
The utility model discloses in, still be equipped with anti-jamming circuit between 24VDC and the 24V commentaries on classics 5V for prevent outside electromagnetic interference and because the wrong report police that electrostatic pulse arouses.
Has the advantages that: book coverCan effectively measure CO in the carbon dioxide incubator2The concentration of (c).
Drawings
These and other advantages of the invention will become apparent from the following more detailed description of the invention, when taken in conjunction with the accompanying drawings and detailed description.
FIG. 1 is a schematic structural diagram of an embodiment;
FIG. 2 is a schematic diagram of the electrical connections of the carbon dioxide detector.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Example (b):
as fig. 1, this embodiment provides a carbon dioxide incubator calibrating device, including four telescopic links 1, the contained angle between the two adjacent telescopic links is 90 degrees, four telescopic links 1 form base 2, and base 2's central point puts the department and is equipped with middle part lifter 3, and the tip of four telescopic links corresponds respectively and is equipped with a tip lifter 4, corresponds respectively on middle part lifter and the tip lifter and is equipped with a couple 5, corresponds on every couple and is equipped with a carbon dioxide detector 6.
In this embodiment, the carbon dioxide detector 6 is an infrared carbon dioxide detector.
In this embodiment, all be equipped with the scale on middle part lifter and the tip lifter, the height of convenient control regulation carbon dioxide detector 6.
Referring to fig. 2, in this embodiment, the carbon dioxide detector is electrically connected to the CPU through the AD converter, and the CPU receives an RS485 signal from the carbon dioxide detector, converts the signal into a serial port signal, and uploads the serial port signal to the CO2Gas concentration display for displaying CO2The real-time concentration of the gas.
In this example, CO2The gas concentration display is powered by 24VDC, which is converted to 5VDC power for the CPU and carbon dioxide detector.
In this embodiment, an anti-interference circuit is further disposed between 24VDC and 24V to 5V to prevent external electromagnetic interference and false alarm due to electrostatic pulses.
The present embodiment is also equipped with an infrared remote control for setting, testing, performing calibration steps, etc.
This embodiment is when using, height adjustment middle part lifter 3 and tip lifter 4 of measuring as required for carbon dioxide detector 6 reaches suitable height, then closes the incubator, and carbon dioxide detector 6 begins to measure through infrared remote controller control, and carbon dioxide detector passes through AD converter electric connection to CPU, and CPU receives the RS485 signal that comes from carbon dioxide detector, and converts serial ports signal upload to CO to2Gas concentration display for displaying CO2And (4) carrying out reading calibration on the real-time concentration of the gas.
The utility model provides a carbon dioxide incubator calibrating device, the method and the way of specifically realizing this technical scheme are many, above only the utility model discloses a preferred embodiment should point out, to the ordinary skilled person in this technical field, not deviating from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements and moist decorations, these improvements should also be regarded as with moist decorations the utility model discloses a protection scope. All the components not specified in the present embodiment can be realized by the prior art.
