Embodiment 1

[0042] This embodiment provides a kind of ozone opening test system, is used for carrying out ozone opening test to the built-in ozone generator in the multiple gas calibrator that lacks photometer; Ozone generator: ozone is generated by air through 185nm ultraviolet irradiation , by changing the light intensity or flow to change the concentration of ozone. Ozone opening: the opening degree of the ozone generator, the measurement unit is 0% to 100%, when the gas enters the ozone generator, the ozone generation is controlled by adjusting the power of the ozone generator or by adjusting the valve connected to the ozone generator the opening degree of the device. In the process of ozone transfer, when the multi-component gas calibrator is not equipped with a photometer, it is necessary to test the opening of the ozone value output by the ozone generator in the multi-component gas calibrator to determine the output ozone concentration value as the target concentration value.

Embodiment 2

[0053] This embodiment 2 discloses an ozone opening test method. The purpose of the ozone opening test is to clearly determine the corresponding opening value of the ozone generator under a certain target concentration value, so that when the ozone generator is applied, it is only necessary to follow the opening of the ozone generator. The ozone of the target concentration value can be obtained by releasing the ozone at the concentration value. This test method is applied to the above-mentioned ozone opening test system.

[0054] figure 1 It is a method flow chart of the ozone opening test method in Example 2 of the present invention.

[0055] see figure 1 , the test method includes:

[0056] Step 201: Obtain a target concentration value.

[0057] Step 202: Obtain the opening value of the ozone generator to be tested.

[0058] Step 203: Send an open command to the solenoid valve corresponding to the ozone generator to be tested according to the opening value to be tested,...

Abstract

The invention discloses an ozone opening degree testing system and method. The gas inlet of the ozone calibrator in the test system communicates with the gas outlet of the built-in ozone generator in each multi-component gas calibrator; a solenoid valve is arranged on the communication pipe between each ozone generator and the ozone calibrator; the industrial computer The communication interface of the multi-serial port communication card is connected to the bus interface, and the multiple ports of the multi-serial communication card are respectively electrically connected to the ozone calibrator, the digital quantity collector and a plurality of ozone generators; the multiple output interfaces of the digital quantity collector are respectively It is electrically connected with multiple solenoid valves; the industrial computer is used to output control instructions to the ozone calibrator and collect the concentration value detected by the ozone calibrator, adjust the opening value of the solenoid valve corresponding to the ozone generator to be tested, and close the ozone generator to be tested. Solenoid valve other than the solenoid valve corresponding to the generator. The ozone opening test system and method of the present invention can reduce the investment of time and effort.

Description

technical field [0001] The invention relates to the field of ozone opening test, in particular to an ozone opening test system and method. Background technique [0002] In the ozone value transfer system, when the multi-gas calibrator is not equipped with a photometer, it is necessary to test the opening of the ozone value output by the multi-gas calibrator to determine the output ozone concentration value as the target concentration value. When using a certified ozone calibrator to test the ozone opening of the multi-gas calibrator, the current technology is limited to the traditional manual method. The following is an example to illustrate the process of manual testing: the opening test of the multi-component gas calibrator is performed with the goal of outputting an ozone concentration of 100ppb from the multi-component gas calibrator. After the ozone calibrator is correctly connected to the multi-gas calibrator, the multi-gas calibrator outputs 5% of the ozone opening, ...
