In particular, for the display lamp for displaying the sensor parameters of the equipment, when the indicator lamp displays green, the parameter represented by the indicator lamp is in a safe range; when the indicator light displays yellow, the parameter represented by the indicator light is in an unhealthy range; when the indicator light displays red, the parameter represented by the indicator light is in a dangerous range.
Fig. 2 is a flow chart of the operation of the measurement and control system of the VOC integrated processing apparatus provided in the present invention, and the operation of the measurement and control system described in fig. 1 will be described in detail with reference to fig. 2.
Firstly, after the equipment is powered on, the MCU performs self-checking to confirm that each sensor and each subcomponent control module are on-line. If the device is used for the first time, the device enters an automatic mode later because the mode parameter of the device is set to the automatic mode by default; various sensor parameters of the equipment are preset values according to corresponding national standards, and a user does not need to set the parameters by himself; the MCU of the equipment can periodically confirm whether the user changes the operation mode parameters, so that the user can change the operation mode of the equipment at any time.
Before entering the running mode, the MCU reads all sensor parameters, the MCU can preferentially confirm whether the carbon monoxide parameters exceed the standard, if the parameters exceed the standard, corresponding carbon monoxide indicating lamps on the equipment display red, and meanwhile, the buzzer buzzes uninterruptedly, so that the carbon monoxide in the environment of the user is reminded to be in a dangerous range; when the operation is performed, the equipment directly skips the operation mode and circularly performs carbon monoxide parameter judgment and alarm until the user performs further operation or the carbon monoxide parameter is reduced to be within a safe range.
And after the carbon monoxide parameter is judged to be the safety value, the MCU executes a corresponding operation mode according to the mode parameter in the flash.
In a silent mode, the MCU can adjust the power of the fan, the microwave source and the oxygen anion generating source to be the lowest through the switch control system, and the silent mode mainly focuses on the quiet degree of equipment and does not react to the change of environmental parameters.
In the full power mode, the MCU can adjust the power of the fan, the microwave source and the oxygen anion generating source to the maximum through the switch control system, and the mode mainly focuses on the purification speed of the equipment, so that the purification efficiency of the equipment cannot be controlled.
In the automatic mode, the MCU can confirm all the collected sensor parameters and dynamically control the switch control system; through the analysis of the formaldehyde parameter and the odor parameter, the MCU can correspondingly adjust the power of the microwave source so as to control the purification speed of the MW-LEP; through the analysis of PM2.5 parameters, the MCU can correspondingly adjust the power of the oxygen anion generating source and the opening number of the oxygen anion generating heads so as to control the emission number of the oxygen anions to control the purification speed of the PM 2.5; the MCU can simultaneously control the fan speed by combining the parameters.
After the device enters an operation mode, the mode parameters of the current mode are displayed on the indicator lamps for displaying the mode parameters of the device, and all the sensor parameters are displayed on the corresponding sensor parameter indicator lamps at the same time.
After performing the above operations, the device will enter a self-generating compound safety check state. For the equipment using the MW-LEP technology, the most important self-generating compound is ozone, and the detection of the concentration of ozone generated by the equipment is also an important step for judging the safety of the environment.
By confirming the parameters of the ozone sensor and comparing the parameters with the indexes prestored in the MCU, the MCU can judge the range of the ozone discharge amount of the equipment; if the ozone is in the unhealthy range and the ozone exceeds the standard, the MCU can enable the ozone indicating lamp to display yellow and simultaneously enable the buzzer to sound low, so that the ozone discharge amount of the user equipment is reminded to exceed the standard, and the user equipment needs to be temporarily away from the equipment or further operate the equipment.
After judging that ozone exceeds the standard, the MCU can also judge whether ozone exceeds the range, if so, the ozone is in a dangerous range, at the moment, the MCU can enable the ozone indicating lamp to display red, and meanwhile, the buzzer buzzes for a long time, so that the ozone discharge amount for warning the user equipment is in a first-in-range. If the user does not operate any further, the MCU starts a timer and sets the mode parameters of the equipment to be in a mute mode; if the ozone parameter is still in the dangerous range after the timer is accumulated to a preset value, the equipment can be directly and automatically shut down.
After all the operations are executed, if the device still runs normally, the MCU will start to judge whether the user changes the mode parameters again, and then enter a new cycle.
Although the present invention has been described with reference to the above embodiments, it should not be construed as being limited to the scope of the present invention. Any variations and modifications within the spirit and scope of the invention may occur to those skilled in the art to which the invention pertains.
