And S50, analyzing the influence of the comprehensive working environment on the working condition of the equipment according to the first working condition information and the second working condition information.
Particularly, by configuring the control system, the temperature and humidity, the dust concentration or the water mist concentration in the test cabin can be singly adjusted and maintained or compositely adjusted and maintained after the temperature and humidity system, the air flow system and the coal dust system are started.
For example, the dust concentration is kept within a certain range by composite regulation at a specific temperature and humidity. Specifically, the range value of the dust concentration is set to be a-b in the control system, and the temperature and the humidity in the test cabin are adjusted to be a certain value through a temperature and humidity system. Then starting a coal dust system to raise dust, increasing the dust concentration in the air of the test chamber, and regulating and stopping the operation of the coal dust system and starting a spraying mode of a spraying and humidifying module of a temperature and humidity system by a control system when the dust concentration parameter acquired by a dust sensor shows that the dust concentration reaches b; when the dust concentration parameter acquired by the dust sensor shows that the dust concentration reaches a, the operation of the spraying humidification module is stopped by the control system, and the coal dust system is started again to raise dust. The dust concentration can be kept within a certain range under specific temperature and humidity by the cyclic reciprocating.
It will be appreciated that as the spray concentration of the spray humidification module increases, the dust concentration gradually decreases.
Therefore, the comprehensive operation environment under the coal mine can be simulated really, and working condition experiments of equipment and the like in various underground operation environments are facilitated.
