Description
Technical Field
The utility model belongs to the technical field of the sensor, specifically be a testing arrangement of sensor uniformity.
Background
The consistency of the sensors refers to whether the response amplitudes and the response times of a plurality of sensors of the same type to the same signal source are consistent, which is particularly important when positioning measurement or multi-point simultaneous measurement is performed. TVOC sensor, PM2.5 sensor and CO2 sensor are widely applied in the technical field of air purification. Many transportation links are carried out in the process of purchasing the sensor, so that whether the performance of the sensor is intact before the sensor is used is unknown. The most common method of testing sensor consistency is to leave a single room for testing in a closed space, usually a laboratory, and throw in a source of contamination, release the contamination, and when the concentration reaches the desired value, record the readings of the various sensors. The drawbacks of this method are mainly: 1) operating in large spaces, the concentration values of pollutants are often uncontrollable; 2) the amount of contaminants required is large, it is desired that the contaminants be uniform, it takes a long time to wait, and it is difficult to make the contaminants uniform even by stirring.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problems that 1, the concentration of pollutants with consistency of a sensor is tested in a large space and is uncontrollable; 2. the contaminants are not uniform in a large space.
In order to solve the technical problem, the utility model discloses a technical means is:
a sensor consistency testing device is a closed box body, a pollution source feeding hole is formed in the upper panel of the box body, a stirring fan is arranged on the rear panel of the box body, and a fan replacing and an anion generator are arranged on the side panel of the box body; the front panel of the box body is provided with a control panel which is connected with a stirring fan, a fan replacing fan and a control circuit of the negative ion generator; the box body is internally provided with a plurality of sensors, each sensor is independently provided with a display screen, and the sensor numerical value display screen is arranged on the front panel.
The utility model discloses the advantage: 1. the test device has small volume and small occupied space; 2. the amount of pollutants in the testing device is controllable; 3. the testing device has small space and is provided with a stirring fan to uniformly stir the pollutants; 4. the operation is simple.
The utility model discloses an optimal scheme has:
the pollution source throwing hole is provided with a tobacco flake throwing cylinder, the tobacco flake throwing cylinder is arranged in the box body, the cylinder body is uniformly provided with air holes, the top of the tobacco flake throwing cylinder is sleeved with the pollution source throwing hole, and the cylinder opening is provided with a sealing plug.
The upper panel of the box body is designed into a detachable sealing cover structure.
Drawings
FIG. 1 is a view showing an internal installation structure of a cartridge;
fig. 2 is a perspective view of the testing device.
Description of reference numerals: the device comprises a box body 1, a stirring fan 2, a sealing plug 3, a tobacco flake putting barrel 4, negative ions 5, a ventilation fan 6, a control panel 7, a sensor numerical value display panel 8 and a sensor 9.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
the sensor consistency testing device shown in figures 1 and 2 is a closed box body 1, a pollution source feeding hole is arranged on the upper panel of the box body 1, a stirring fan 2 is arranged on the rear panel of the box body 1, and a fan exchanging 6 and an anion generator 5 are arranged on the side panel of the box body; the front panel of the box body 1 is provided with a control panel 7, and the control panel 7 is connected with a stirring fan 2, a ventilation fan 6 and a control circuit of the anion generator 5; a plurality of sensors 9 are arranged in the box body 1, each sensor 9 is independently provided with a display screen, and a sensor numerical display screen 8 is arranged on the front panel.
In order to avoid the direct problem of scattering the clearance of being not convenient for in the box body of cigarette ash after the smoked sheet burning, the utility model discloses a section of thick bamboo 4 is put in to the smoked sheet, and section of thick bamboo 4 is put in the pollution sources and is thrown in the hole, and in the barrel body sunk into the box body, the smoked sheet was put in 4 barrels and is established even gas pocket, and the hole connection is put in at the barrel top and pollution sources, and the bung hole is equipped with sealing plug 3, and sealing plug 3 resumes 1 encapsulated situation of box body after the smoked sheet drops into the flue gas and forms.
The utility model discloses a box body is for convenient maintenance, inside parts installation, and its top panel sets up to the sealed structure of dismantling.
Fig. 1 is a perspective view of the testing device, and the process of detecting the consistency of the sensors is as follows:
1) a plurality of sensors are connected in the device, and data lines of the sensors are led out from the rear side of the box body and connected on a display screen capable of displaying the concentration of a plurality of groups of sensors simultaneously.
2) The tobacco flakes or other pollution sources are thrown into the throwing hole, and then the throwing hole is plugged and sealed by a rubber plug.
3) The concentration of the pollutants in the box body is set to be a designated value. Since the amount of the contaminants released when the contaminants are thrown into the tank from the inlet is large, the concentration of the contaminants in the tank needs to be reduced if the concentration of the contaminants in the tank is desired to reach a specified value. At the moment, the ventilating fan and the negative ion generator start to work, and because the filtering element is arranged in the ventilating fan, the air introduced by the ventilating fan is clean air, and meanwhile, the negative ion generator plays a role in purifying the air in the box body. The rubber plug on the putting hole is pulled out, so that the polluted air in the box body can be discharged. When the concentration of the pollutants in the box body is diluted to be close to a specified value, the stirring fan is automatically started to uniformly stir the air in the box body, and when the concentration of the pollutants in the box body reaches the specified value, the ventilation fan and the negative ion generator stop working.
4) The readings of the various sensors on the display screen are observed and compared.
5) And comparing a plurality of groups of values by the same method to obtain whether the consistency of the sensor is qualified or not.
The utility model discloses beneficial effect: 1. the test device has small volume and small occupied space; 2. the amount of pollutants in the testing device is controllable; 3. the testing device has small space and is provided with a stirring fan to uniformly stir the pollutants; 4. the operation is simple.
