Description

technical field [0001] The invention belongs to the field of testing, and more specifically relates to a method and a device for intensively simulating various environmental quantities of equipment under test. Background technique [0002] In the prior art, the centralized environmental monitoring equipment is a multifunctional module used for environmental monitoring of communication equipment, which comprehensively integrates various detection functions for environmental quantities such as humidity, temperature, flooding, anti-theft, and smoke. In the process of research and development of these functions, it is necessary to conduct multiple tests on the centralized monitoring equipment for different environments. At the same time, in order to test these functions most comprehensively, it is necessary to create various types of environmental quantity stimuli during each test. In the existing test process, the environmental sensor is usually used as the excitation input so...

AI Technical Summary

Problems solved by technology

In the existing test process, the environmental sensor is usually used as the excitation input source of the environmental power centralized monitoring equipment, so various sensors are required in the test, and various types of environmental quantities need to be manufactured to be transmitted to the sensor, for example, it is necessary to manufacture 0 %-100% different air humidity, and then need to create different ambient temperatures from -10 to 40 degrees, also need to create flooding, smoke with different concentrations, etc., so the simulation of various environmental quantities requires a very large workload , and very cumbersome

[0003] In the actual test, because different sensors are not integrated together, the mixing of sensors is easy to cause test errors and affect the test efficiency, and the establishment of the sensor test environment is also very troublesome.

[0004] At the same time, there are the following difficulties in the manufacture of these environmental quantities:

[0005] 1. It is difficult to manufacture, and some environmental quantities cannot be controlled, such as smoke concentration

[0006] 2. The amount of environment that can be manufactured cannot cover the range required for testing

For example, it is impossible to make 0% humidity, and similarly, it is very difficult to make a temperature of -10 degrees

[0007] The defects of the above-mentioned prior art have greatly affected the improvement of the test efficiency and product quality of the centralized monitoring equipment for the environment. At the same time, because the service life of some environmental sensors used in the test is very small, the cost of the test has also been greatly increased.
