Abstract
The utility model discloses an air quality grade measuring device. The device comprises a calculation chip, wherein the calculation chip is respectively connected with a zero point data acquisition circuit and a data memory. The air quality grade measuring device has the beneficial effects that the air pollution grade data vary dynamically, so that the measurement result is precise.
Description
Technical field
The utility model relates to the Detection of Air Quality technology, particularly a kind of air quality level measurement device.
Background technology
The evaluation of air pollution grade is a ring important in the environmental protection data; traditional evaluation mode is; choose air sample; by gas sensor, air quality is measured; and the sample data result recorded in the data result of measurement and clean air is compared, and then draw the evaluation value of the class of pollution.But this air pollution grade numerical value is an absolute value, is not relative, and it can not adjusted automatically along with the difference of their location, and this just makes the air pollution level data accurate not.
Summary of the invention
The purpose of this utility model is in order to address the above problem, and has designed a kind of air quality level measurement device.
Realize that the above-mentioned purpose the technical solution of the utility model is, a kind of air quality level measurement device, this device comprises compute chip, and compute chip is connected with data-carrier store with the zero data Acquisition Circuit respectively.
Described zero data Acquisition Circuit is to be in turn connected to form closed-loop path by power supply, gas sensor and pull-up resistor, and is parallel with voltage table on pull-up resistor.
Described gas sensor is TGS2602 type catalytic combustion method gas sensor preferably.
Described zero data refers to the electric signal that sensor sends in clean air.
The voltage of described power supply is 5V.
The air quality level measurement device that utilizes the technical solution of the utility model to make, can realize kinetic measurement and the renewal of air pollution grade, makes the class of pollution data of air and affiliated environment combine closely, and realized that the air pollution grade dynamically evaluates.
The accompanying drawing explanation
Fig. 1 is the structural representation of air quality level measurement device described in the utility model;
In figure, 1, compute chip; 2, zero data Acquisition Circuit; 3, data-carrier store; 4, power supply; 5, gas sensor; 6, pull-up resistor; 7, voltage table.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described, as Fig. 1 is the structural representation of air quality level measurement device described in the utility model, as shown in the figure, a kind of air quality level measurement device, this device comprises compute chip 1, and compute chip is connected with data-carrier store 3 with zero data Acquisition Circuit 2 respectively.Wherein, described zero data Acquisition Circuit is to be in turn connected to form closed-loop path by power supply 4, gas sensor 5 and pull-up resistor 6, and is parallel with voltage table 7 on pull-up resistor.Wherein, the preferred TGS2602 type catalytic combustion method gas sensor of described gas sensor; Described zero data refers to the electric signal that sensor sends in clean air; The voltage of described power supply is 5V.
The order that the utility model will reach is to make gas sensor adjust automatically zero data according to current air quality, and the electric signal that in clean air, sensor sends, realize the kinetic measurement of gaseous mass.The method realized is to measure chip collection, calculating, the renewal lasting to zero data by gas sensor, makes the class of pollution of corresponding other contaminated air also can upgrade.
What catalytic combustion method gas sensor was selected is the TGS2602 type, and what characteristic curve was used is the PPM value of organic solvent pollution and the relation curve of sensor output electrical signals.It can effectively detect the air regime of the organic solvent pollutions such as formaldehyde, toluene.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art have all embodied principle of the present utility model to some changes that wherein some part may be made, within belonging to protection domain of the present utility model.
