Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to an efficient and traceable calibration and testing system for sensors. Background Technology

[0002] Sensors undergo testing before leaving the factory to distinguish between good and defective products. Currently, testing is conducted using a testing cabinet. However, conventional testing methods have a limited number of tests, resulting in high costs per sensor. Furthermore, the low number of sensors tested at one time increases manpower and prolongs the testing time for the entire batch, leading to slower delivery and a tighter overall production process. Additionally, it is difficult to distinguish between good and defective products after testing, making it impossible to effectively trace the products after they are sold. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model discloses an efficient and traceable calibration and testing system for sensors. This utility model sets up three test chambers in the test box to achieve the purpose of testing multiple sensors at once, reducing the cost of calibration and testing a single unit, saving labor, shortening the construction period, and speeding up the delivery speed.

[0004] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0005] A high-efficiency, traceable calibration and testing system for sensors includes a test chamber with three test compartments on one side of the chamber's opening. Each test compartment has a door at its opening. Multiple fixtures are installed inside each test compartment, and multiple sensors to be tested are installed on each fixture. Communication equipment is installed in each test compartment. The communication equipment is used by an external test computer to calibrate and test the sensors on the fixtures. The communication equipment is connected to a switch, which is connected to the external test computer. A display screen and a switch are located on the front of the test chamber. An exhaust fan is located on one side of the test chamber, and the exhaust fan's outlet has a duct that connects to the outside.

[0006] The communication device is a bidirectional serial communication hardware.

[0007] The test chamber has ventilation slots distributed on it, and the test chamber is connected to the test box through the ventilation slots. The inner wall of the test chamber is equipped with filter cotton, which covers the ventilation slots.

[0008] At least two support plates are symmetrically distributed on the inner wall of the test chamber. The fixture is installed on the corresponding two support plates and connected to the communication equipment.

[0009] The test chamber is equipped with a lighting lamp on its top surface, which is electrically connected to a switch.

[0010] A smoke generator is installed at the bottom of the test chamber, and the smoke generator is electrically connected to a switch.

[0011] The test chamber is also equipped with a stirring fan at the bottom. The stirring fan is electrically connected to the switch and is located below the smoke generator. The stirring fan and the smoke generator are set up in correspondence.

[0012] The fixture has equidistant arrays of fixing holes, and each sensor to be tested is installed in each fixing hole. Each fixing hole has an indicator light on one side.

[0020] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0021] Combined with appendix Figures 1-5A high-efficiency traceable calibration and testing system for sensors includes a test chamber 1. Three test chambers 7 are located on one side of the test chamber 1's opening. Each test chamber 7 has a door 2 at its opening. Multiple fixtures 14 are installed inside each test chamber 7, and multiple sensors to be tested are installed on each fixture 14. Communication equipment is installed inside each test chamber 7. The communication equipment is used by an external testing computer to calibrate and test the sensors on the fixtures 14. The communication equipment is connected to a switch, which is connected to an external testing computer. A display screen 3 and a switch 4 are located on the front of the test chamber 1. An exhaust fan 5 is located on one side of the test chamber 1, and the exhaust fan 5 has an air duct 6 connected to the outside.

[0022] The communication device is a bidirectional serial communication hardware.

[0023] The test chamber 7 is provided with ventilation slots 13, and the test chamber 7 is connected to the test box 1 through the ventilation slots 13. The inner wall of the test chamber 7 is provided with filter cotton 8, which covers the ventilation slots 13. The exhaust fan 5 draws air from the test box 1, which creates a negative pressure in the test chamber 7 and exhausts the air in the test chamber 7. As a result, the particulate matter in the air in the test chamber 7 is adsorbed by the filter cotton 8, which facilitates the purification of the air in the test chamber 7.

[0024] At least two support plates 9 are symmetrically distributed on the inner wall of the test chamber 7. The fixture 14 is installed on the corresponding two support plates 9 and connected to the communication equipment.

[0025] The test chamber 7 is equipped with a lighting lamp 10 on its top surface, and the lighting lamp 10 is electrically connected to the switch 4.

[0026] A smoke generator 12 is installed at the bottom of the test chamber 7, and the smoke generator 12 is electrically connected to the switch 4.

[0027] A stirring fan 11 is also provided at the bottom of the test chamber 7. The stirring fan 11 is electrically connected to the switch 4. The stirring fan 11 is located below the smoke generator 12. The stirring fan 11 is set in correspondence with the smoke generator 12. The stirring fan 11 blows the smoke generated by the smoke generator 12 onto the top of the test chamber 7, so that the smoke concentration in the test chamber 7 is uniform.

[0028] The fixture 14 has equidistant arrays of fixing holes 15, and each sensor to be tested is installed in each fixing hole 15. Each fixing hole 15 has an indicator light 16 on one side. The indicator light 16 is a dual-color light, and the color of the light emitted by the indicator light 16 can quickly distinguish between good and bad products.

[0029] The embodiment describes a high-efficiency traceable calibration and testing system for sensors. In use, the model of the sensor to be tested is first set on the display screen 3, along with the test parameters. Each sensor is then installed in the fixing holes 15 of the fixture 14. The fixtures 14 are then installed on the support plate 9 of the test chamber 7, and connected to the communication equipment within the test chamber 7. After installation, the chamber door 2 is closed, and the lighting 10, stirring fan 11, and smoke generator 12 are turned on via switch 4. The display screen 3 shows that the concentration in the test chamber 7 has reached the set value. An external testing computer then sends signals to each sensor for testing. During the test, the sensors send calibration values ​​back to the testing computer, which are recorded in the computer's database. Each qualified product can be traced using its serial number. After the test, based on the test results, the indicator lights 16 on the fixture 14 emit different colors of light depending on whether the product is good or defective, facilitating worker classification and collection.
