The preset mode is an environment mode set by a user and can be adjusted according to the use habit of the user.
In one embodiment, as shown in fig. 2, the purification control system further includes a cloud server and an internet of things communication module;
the sensing data acquired by the monitoring module also comprises equipment working parameters;
the cloud server is communicated with the control module through the Internet of things communication module;

and the cloud server analyzes the service condition of the equipment according to the first environment parameter and the equipment working parameter to obtain an improved report of the equipment product.
In the invention, the sensors of the monitoring module comprise a wind sensor, a photosensitive sensor, a temperature and humidity sensor, a laser particle counting sensor, an ammeter, an RFID card reader and a fan control panel; the data acquired by the monitoring module comprises a first environmental parameter and an equipment working parameter. The first environmental parameters comprise wind power intensity, illumination intensity, temperature data, humidity data and air pollutant concentration; the equipment working parameters comprise voltage, current, power factor and other electrical parameters of the electric meter, RFID information and fan working parameters.
In the invention, the wind sensor is mounted on the system bus through standard RS 485. Through bus query, the control system app on the android system can acquire the wind power condition of the current air outlet. Whether the fan normally operates or not can be judged according to the condition of wind power, and whether the filter screen needs to be replaced or not after being used for a long time. The wind sensor adopts a hot wire type wind speed sensing principle, has good measurement accuracy for low wind speed, and can detect the change of the wind speed within 1 second as the reaction speed is very fast.
In the present invention, the light sensitive sensor is a sensor configured to implement a user comfort algorithm. The main function of the device is to monitor the illumination intensity in the current environment, determine the backlight brightness of the liquid crystal display screen by the illumination intensity, and determine whether the screen needs to be turned off or not by combining the Beijing time, so that the light pollution is reduced under the condition that a user needs to have a rest. Meanwhile, the operation of the fan is reduced, so that the noise is reduced, and the comfort algorithm of the user is realized. The sensor is also hung on a system bus in an RS485 bus mode, so that the plug and play of the sensor is realized.
In the invention, the temperature and humidity sensor is used for environment detection and has two functions. One is to detect the humidity, and under the condition of overhigh humidity, the service life of the filter screen is greatly reduced, so the maintenance is needed to be carried out in advance, and the service life of the filter screen under the condition of no humidity can be obtained through long-time analysis; the other is temperature detection, and when ambient temperature was lower relatively, because the wind that the clarifier produced can let the human sensation relatively cold, in order to improve user's travelling comfort under this condition, can suitable reduction amount of wind, under the circumstances of guaranteeing the comfort level, accomplish the balance of purification efficiency. The sensor is also hung on a system bus in an RS485 bus mode, so that the plug and play of the sensor is realized.
In the invention, the laser particle counting sensor is an external movable sensor. It is connected with the system by a 2.4G wireless communication mode. Since it is not an on-board sensor, it can be placed at any desired location to test the particle counts of PM0.5 and PM2.5 in air. The level of cleanliness of the air in the current environment can be converted by acquiring the amount of PM0.5 particulate matters. The control system can control the purification efficiency of the equipment according to the requirements of users, and the cleanliness grade required by the users is achieved.
In the invention, the electric meter is mainly used for monitoring the electricity utilization condition of the whole system. It is mounted on the system bus through RS 485. The health condition of the whole system can be known by monitoring voltage, current, power factor and other electrical parameters of the system in real time, if the current, power and power factor of the electric equipment such as a fan and the like are changed beyond a certain range in the switching process, the problem of the electric equipment is possibly caused, and the electric equipment is required to be reported, maintained, detected and replaced in time.
In the invention, the RFID card reader is used for acquiring the identity information of the current consumable filter screen and updating the service life of the filter screen. By adding RFID on the filter network, relevant data of the RFID is recorded into the system during production. Both the date of manufacture and the shipping direction are written to the RFID at the time of shipment. Once the filter screen is installed on the equipment, the RFID card reader can read the information of the RFID and compare the information with the original data on the cloud server through the network. The production, sale, use and other processes of the filter screen can be traced through the RFID. Meanwhile, once the filter screen is invalid, the RFID can be added with an invalid mark, and once the RFID card reader reads the filter screen, the equipment cannot be started, so that secondary pollution is effectively prevented. It is also mounted on the system bus through RS 485.
In the invention, the fan control board is specially designed for a special purification fan customized by the company. The control command of the fan can be acquired from the system bus by RS485, and the current running state of the fan can be sent to the system. It is the only strong electrical system in this system.
In the invention, the Internet of things communication module solves a network communication problem. The system can be independent of wifi, and can communicate with a cloud server as long as a mobile data network is owned. The updating of app application, the updating of advertisement pictures and videos, the uploading of device data and the like are realized.
In the invention, one part of monitoring data acquired by the monitoring module is stored in a local database, and the other part of the monitoring data is uploaded to a cloud server. By analyzing these data, the difference in the use condition of the equipment, the use frequency, and the air cleanliness before and after use can be understood. By collecting the information, the product improvement can be made for the future.
In one embodiment, as shown in fig. 3 and 4, the decontamination control system further includes a mobile monitoring device; the mobile monitoring device is connected to the control module, replaces the monitoring module and is used for controlling the wind power intensity and the temperature and humidity of a local area;
a wind sensor and a temperature and humidity sensor are arranged in the mobile monitoring device; the mobile monitoring device moves in a local area, collects second environment parameters at a plurality of fixed points, and sends the second environment parameters to the control module;
the control module calculates wind strength and temperature and humidity data in the local area according to the second environment parameters; and if the wind power intensity and the temperature and humidity data do not accord with the historical air environment data and the preset mode, sending an adjusting control signal to the purification module.
In the invention, the wind power intensity is controlled by the fan; the humidifier and the dehumidifier are matched with the air conditioner to control the indoor temperature and humidity.
In the invention, the monitoring module is used for monitoring the whole environment, and the control module controls the parameters of the whole environment, such as temperature, humidity, illumination intensity, air cleanliness and the like according to the first environment parameter. However, in practice, the temperature distribution in the space is not uniform, for example, the temperature near the sunshine windowsill is higher than the temperature elsewhere in the room, so that the temperature at the position of the sensor is problematic to replace the overall environmental problem. Therefore, the mobile monitoring device replaces the monitoring module, and aims to control local ambient temperature, humidity and wind strength so as to adjust current environmental parameters and enable the current environmental parameters to meet the requirements of users. When the number of people in the room is less, just can start mobile monitoring device, its beneficial effect has two points: firstly, the comfort level of a user is improved; secondly, the working power of the unmanned area equipment can be properly reduced, and the electric energy is saved.
In one embodiment, as shown in FIG. 5, a configuration sub-module is provided within the control module;
a preset mode is arranged in the configuration submodule and comprises a working mode and a rest mode;
the working mode is used for controlling environmental parameters of a working period;
the rest mode is used for controlling environmental parameters in a non-working period, judging whether the ambient light changes through the photosensitive sensor, and if the illumination intensity is reduced, reducing the working power of the fan and turning off all the display screens;
and if the ambient temperature in the working mode and the rest mode is to be controlled, the air volume of the fan is preferentially controlled.
In the invention, the configuration submodule can cut the module according to different requirements of the equipment so as to meet the requirements of blind users. Through the module configuration page of the app application, the corresponding module hung on the equipment can be selected in a multi-selection mode, and after the module is selected, the software function corresponding to the module can be selected. For example, after the wind sensor and the electric meter are added, software functions such as air quantity display, electric parameter alarm, filter screen service condition detection and the like can be added. Different functions are realized through different configurations, and the requirements of users are finally met.
Besides providing a purifying effect, the purifying device also needs to ensure that the purifying device does not cause trouble to users. The purification devices on the market today have several problems:
first, noise problems. The purification process generates larger noise, which affects the rest of the user.
Second, light contamination. When a user has a rest at night, the rest of the user is influenced by light generated by an indicator lamp, a display interface and the like of the equipment, and particularly, the light is dazzling.
Third, ambient temperature is too cold. In the environment with relatively low temperature, the wind generated by purification influences the body feeling, so that the client has the possibility of blowing and catching a cold.
The invention can solve the problems of noise, light pollution and over-low temperature at night by setting the rest mode:
first, with respect to the noise problem, noise is generated as long as the apparatus is operated, but the noise can be reduced by reducing the air volume. Aiming at the rest habit of the user, a low air volume working mode is adopted in the rest period, and the noise is reduced. And the photosensitive sensor is used for automatically judging ambient light to judge whether a low air volume mode is required or not. Because a person generally turns off a light, pulls a window curtain and the like once the person needs to take a rest, once the environment is dark, the person can be regarded as a premise that the user needs to take a rest.
Secondly, for the problem of light pollution, a timing mode is also adopted to combine with light detection, and all displays are switched to a screen-off state in the rest time and under the condition of low light. If the equipment needs to be awakened, the screen-off state can be recovered within 30 seconds after no operation as long as the display screen is touched.
Finally, for the problem of wind, the current air temperature is detected by using a temperature sensor, and when the temperature is not too low in the non-rest time, the large air volume is allowed, and if the temperature is low, the air volume is adjusted. In the rest time, the low air volume operation is adopted, so that the problem of wind during the sleep of a user is reduced, and the wind catching cold is caused.
In one embodiment, as shown in fig. 5, the control module is further provided with a maintenance sub-module;
the maintenance sub-module obtains the working parameters of the equipment, obtains standard working parameters of the equipment from the cloud server, and judges whether the working parameters of the equipment are abnormal or not according to the standard working parameters;
if the cloud server is abnormal, sending alarm information to the cloud server;
and if the first environmental parameter and the equipment working parameter are normal, collecting the first environmental parameter and the equipment working parameter, analyzing the service condition of the equipment, and obtaining an improved report of the equipment product.
In the invention, when the system monitors that the fan is abnormally operated, the filter screen needs to be replaced or the module works abnormally, the maintenance sub-module sends alarm information to the background cloud server through the Internet of things module, the alarm information is automatically forwarded to maintenance service personnel of the equipment, and a maintenance work order is automatically generated. After receiving the maintenance information and the work order request, the maintenance personnel need to go to the equipment field within 1 day to check the specific operation condition of the equipment, and carry out treatment such as filter screen replacement, module maintenance, problem troubleshooting and the like on the equipment according to the condition. After the work is finished, completing the information completion of the work order at the mobile phone end, and recording and updating the current maintenance work.
In one embodiment, as shown in fig. 2, the control module determines the usage status of the filter screen through a multi-sensor fusion technique:
the control module controls the fan to improve the air quantity, the change rate of the wind power intensity of the air outlet of the filter screen is obtained through the wind power sensor, the change rate of the air pollutant concentration is obtained through the laser particle counting sensor, and the change value of the fan power parameter is obtained through the ammeter; and judging the service life of the filter screen according to the change rate of the wind power intensity, the change rate of the air pollutant concentration and the change value of the power parameter.
In the invention, the actual service life of the filter screen is judged by adopting a multi-sensor fusion technology. At present, filter screens of a plurality of manufacturers adopt a mode of fixing the service life of the filter screens to prompt the replacement of the filter screens, but the method is not very accurate, the service life of the filter screens in a clean environment is longer, but in a polluted environment, the service life of the filter screens is short, and secondary pollution is generated if the filter screens which are used for a long time are used.
Through the multi-sensor fusion technology, the data of the wind sensor, the electricity meter and the laser particle counting sensor are fused, and the judgment on the use state of the relatively real filter screen can be given by judging the size of the wind power of the air outlet of the filter screen, the power and power factors of the fan, the reduction conditions of particles of PM05 and PM2.5 in the air and combining the use duration of the filter screen.
When the filter screen reachd life, the amount of wind of air outlet can reduce because the inside jam of filter screen, and the fan is in order to provide sufficient wind pressure simultaneously, and power also can rise, and power factor can improve, and the purification efficiency of particulate matter can reduce in the whole environment, and these all are the life's of differentiateing the filter screen basis. The single sensor data is taken as the basis, the misjudgment condition exists, but the accuracy can be improved with high probability by overlapping a plurality of sensor data through the multi-sensor fusion technology.
In one embodiment, as shown in FIG. 5, the decontamination control system further includes a display screen; the control module also comprises an advertisement sub-module;
the display screen realizes man-machine interaction, and controls the control module through a touch key for equipment control;
and the display screen enters a dormant state and enters an advertising mode through the advertising submodule for product propaganda.
In the invention, the liquid crystal display screen with touch control is an important ring of man-machine interaction, the previous key type control mode can be omitted through touch control, and people who often use smart phones and pads are more accustomed to.
