Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Embodiment case one:
a method of controlling a dust removal system, comprising: when the dust on the filter mechanism is more, the signal acquisition device sends a signal to the control system, the control system transmits the signal to the execution device, and the execution device changes the filter mechanism.
The signal acquisition device is a pressure sensor.
The filtering mechanism is filter cotton.
Further, the control method further includes:
when the pressure signal detected by the pressure sensor is larger than a set pressure threshold, the pressure sensor sends a pressure overrun signal to a control system, and the control system judges whether i is smaller than or equal to n or not;
if yes, neglecting the signal;
if not, the executing device changes the filter cotton;
wherein i is the actual day time after the filter cotton is replaced each time; n is the number of days of replacing the filter cotton signal that needs to be ignored after each replacement of the filter cotton.
Further, the control method further includes:
when i=n+m, and the control system does not receive the pressure overrun signal sent by the pressure sensor, namely, the pressure signal detected by the pressure sensor is continuously smaller than a set pressure threshold value, the executing device replaces the filter cotton;
wherein n+m is the number of days when the pressure overrun signal is not received but the filter cotton needs to be automatically and forcedly replaced.
The n days means that after the filter cotton is replaced once every time, the signal of the filter cotton to be replaced is received in n days to be ignored, so that the purpose of foolproof and false alarm prevention is to prevent that the filter cotton is replaced just today, and the filter cotton is blocked by dust and needs to be replaced the next day, which is not practical. The actual application scene is seen in the specific n days, the environment used at present has larger external dust and poorer conditions, and the pulp tableware products are produced, so that the requirements are higher, and the n is set for 7-30 days (the n is determined according to the specific placement position). The n+m days are that the filter cotton is automatically and forcedly replaced once in the n+m days if the pressure overrun signal is not received, and the aim is still foolproof; assuming that a certain pressure sensor is bad, a replacement signal can not be sent forever, and the corresponding dust removal module can not replace the filter cotton forever, so that the problem can be solved by setting n+m days and automatically and forcedly replacing the filter cotton once if the pressure overrun signal is not received. The specific m days depends on the application scenario and also on the magnitude of the n value. For example, if n is large, m is also large, and a small point can be set, after all, the filter cotton is used for a long time; if n is not large, m can be set to be larger, so that the user can judge whether the user needs to replace the device for a long time, and the automatic control system can be said to have a larger function.
Further, the control method further includes:
when the control system receives the pressure overrun signal sent by the K-2 times of pressure sensors, the control system transmits a signal to the touch screen, and the corresponding equipment number on the touch screen displays yellow and gives a yellow warning;
where K is the maximum capacity of the filter cotton of the roller shutter device.
Further, the control method further includes:
when the control system receives the pressure overrun signal sent by the K-1 time pressure sensor, the control system transmits a signal to the touch screen, and the corresponding equipment number on the touch screen displays red and gives a red alarm;
if the control system receives the pressure overrun signal of the pressure sensor again, the control system does not respond until new filter cotton is replaced on the roller shutter device.
When receiving the signal from the sensor for K-2 times, the curtain rolling device of the dust removing system automatically changes the filter cotton for K-1 times (one filter cotton in the current use is replaced for K times in one time), and the maximum capacity is K times, namely, one filter cotton is left, so that yellow warning prompt is given; when a signal from the sensor is received K-1 times, namely, when the roller shutter device automatically changes the filter cotton K times, one filter cotton is not available, and a red warning indicates maintenance personnel that the roller shutter device does not have spare cotton and needs to be changed in a complete set.
Implementation case two:
a method of controlling a dust removal system, comprising:

wherein J is the number of times the pressure sensor sends a pressure overrun signal; k is the maximum capacity of the filter cotton of the roller shutter device.
Further, the control method further includes:
acquiring a control mode of a control system, wherein the control mode comprises manual control and automatic control;
if the control system is manually controlled, judging whether the filter cotton needs to be replaced or not; if yes, the execution device is controlled to replace the filter cotton; if not, neglecting;
if the control system is automatically controlled, the pressure sensor acquires a pressure signal; when the pressure signal is larger than the set pressure threshold, the pressure sensor sends a signal to the control system, the control system transmits the signal to the execution device, and the execution device replaces the filter cotton.
When dust on the filter cotton is accumulated to a certain amount, the pressure sensor generates a signal, the signal is processed by the control system and transmitted to a corresponding execution mechanism on site, and the filter cotton is replaced once. To avoid mishandling, the received signal is automatically ignored within n days.
