The following detailed description of the embodiments of the present invention is provided in connection with the accompanying drawings for the purpose of understanding and controlling the technical solutions of the present invention, so as to define the protection scope of the present invention more clearly.
In view of the functional defects of the conventional air port, the air channel air port structure of the purification system is researched and innovated by the designer, the laser projection type air port and the functional realization of the air port are provided, and the intelligent and clear display of the air quality is realized mainly by additionally arranging a sensing device on an air port base body and connecting a microprocessor and a communication module.
In order to fully and carefully show the structural features of the present design innovation, the technical outline thereof will be understood by referring to fig. 1 and 4. The laser projection type air port is provided with a body 1 which is positioned and arranged on the wall surface and is in butt joint with an air duct for ventilation, the diversity of the section shape of the air duct is better, the body is mainly in a circular sleeve shape or a rectangular sleeve shape in appearance, and the body is embedded in a wall surface preformed hole and is sealed at the periphery. In the illustrated embodiment, a circular sleeve-shaped tuyere body structure is selected, but the actual application is not limited thereto. The tuyere body 1 is further provided with auxiliary elements such as fan blades for guiding the airflow with adjustable direction, which are not important for the protection of the present application and therefore the detailed description is omitted. The characteristics as this technical innovation are dedicated to the optimization of wind gap structure and function, based on body 1 integration installed laser projection display module 2, MCU, air quality detection module 3, human response module 4, wherein air quality detection module 3 gathers air quality data and feeds back and transmits into MCU by the air current, human response module surveys human activity or action and feeds back and transmits into MCU towards the wind gap outside regionality, and MCU and laser projection display module divide the way wireless access to computer at higher level, and laser projection display module controlled orientation and wind gap relative department projection display air quality data.
Based on the scheme outlined above, the air port can simultaneously realize the real-time monitoring of the air quality of the air flow and the display of the number indicating state of the arrival identification of response personnel. Wherein, air quality detection module 3 can be according to the various microsensors that different air detection demand standards chose for use, and this type of sensor product maturity and scale are great. Including but not limited to PM2.5 detection sensor, carbon dioxide detection sensor, temperature and humidity detection sensor, TVOC detection sensor, formaldehyde detection sensor etc.. Commercially available products such as voltage type air quality sensor module QS3012, japanese figaro air quality sensor/VOC sensor-TGS 2600, etc. certainly when selecting such sensors according to differences in different duct specifications, it is also necessary to select a sensor element with a size adapted from the viewpoint of installation convenience.
The human body induction module 4 can include but is not limited to an infrared induction probe, a microwave radar induction head or the combination of the infrared induction probe and the microwave radar induction head for multiplexing, and the human body induction module is attached to the fan blade towards the air outlet direction. In the prior art, a variety of sensors for sensing human body are widely used and are widely used, such as a voice-operated sensor head or a touch sensor head in a corridor, in this embodiment, it is preferable to combine and multiplex an infrared sensing probe and a microwave radar sensor head, so that the infrared sensing probe and the microwave radar sensor head can be fully utilized and can make full use of the performance of both (detailed later), and the accuracy of sensing personnel is improved.
In addition, the air quality detection module 3 and the human body induction module 4 are both connected to the MCU, so that the electric energy supply of the corresponding sensor realization function is realized by electrifying the MCU system. In contrast, the laser projection display module 2 is not only interconnected with the upper computer through the data signal, but also inevitably provided with a power line for accessing and supplying energy together with the MCU. The energy supply and adaptive voltage transformation of the electronic device belong to the conventional technical means in the industry and are not the important characteristics protected by the application, so the description and implementation are omitted.
Above be the basic hardware of wind gap data acquisition and environment dynamic monitoring, for the user observation of being convenient for simultaneously, this scheme introduces and has integrated laser projection display module assembly 2. The current microelectronic technology development has produced many miniature projection devices, such as those widely used in smart phone cases, teaching sticks, or other small projectors for home use. And the optical imaging system of the core is actually smaller than the palm of the adult, so that the optical imaging system is easy to be integrally installed in the air port without influencing the air flow. From the perspective of display, the orientation of the air ports is often different due to the variability of the layout of the air ducts. For the condition that the air opening faces downwards, the situation that laser projection imaging is easier to observe on the ground is considered, so that the ejection direction of the laser projection display module is consistent with the axial direction of the air opening, and projection is displayed on the ground. And to the wind gap towards lateral space setting, if laser projection display module group is according to aforementioned implementation this moment, then the imaging definition will receive the distance influence and can't satisfy the requirement, and be unfavorable for the impression of observing. Therefore, the laser projection display module can be considered to form an image on the wall surface of the side wall or the top wall, so that the emergent direction of the laser projection display module is axially staggered and deviated with the air opening, and the projection is displayed on the wall surface or the top surface.
In order to further improve the practicability, the laser projection display module can be further internally provided with a remote control receiver for adjusting the developing definition, and a user can adjust the image definition in a remote control mode after the product is installed, so that the operation is performed by referring to an adjusting method of a common projector.
On the basis of the hardware and the principle, the implementation method of the laser projection type air port mainly comprises four parts of air monitoring, human body activity sensing, data interaction and laser projection imaging. Specifically, the air quality is monitored in real time, the air quality is analyzed in real time for airflow by utilizing an air quality detection module tightly attached to an air port, and data are collected by an MCU (micro control unit); human body activity induction, wherein a human body induction module is used for triggering a signal for human body activity or action outside the air outlet and transmitting the signal to the MCU; data interaction, namely polling the MCU by an upper computer at regular time to acquire air quality data and a human body induction signal, and outputting a driving signal and an image data packet containing the air quality data and the air outlet running state to the laser projection display module; and laser projection imaging, wherein the laser projection display module is driven to switch the operation mode, and the image data packet received from the computer is projected and displayed on the ground or the wall.
The details of the respective operation flows of the MCU and the higher-level computer are shown in fig. 2 and 3. Fig. 2 is a program flow chart of the MCU, which includes the following steps:
1. after the system is powered on and started, a register, an IO port and the like of the MCU are initialized, and preconditions are provided for normal operation of the system.
2. Once the upper computer of the MCU monitors the interruption of the serial port, the system can analyze whether the data is a data query instruction of the upper computer, if so, the acquired data is transmitted to the upper computer through the wireless radio frequency transceiving module, and the upper computer executes related programs.
3. Because each sensor samples for a certain period, the timer needs to time for T seconds, and then sends a sampling data instruction, and after data is obtained, the data is stored in a register for waiting calling.
4. Carry out data acquisition to microwave radar response module regularly preferentially, mainly consider that microwave radar's detection distance is far away than infrared induction, and the penetrating power is also stronger, and the response angle can reach 360 degrees, and no blind spot can pierce through glass and thin plank, and is different according to power, can also pierce through the wall of different thickness, and it still has anti radio frequency interference ability reinforce, does not receive temperature, humidity, light, air current, dust influence, can not take place the condition of erroneous judgement. When the microwave radar senses that the person approaches or moves away at a certain speed, a reaction is triggered. However, once personnel are motionless, microwave radar only senses background signal, MCU then thinks that no person is in the field false image and causes the wrong report, the system can carry out infrared detection response module data acquisition this moment, because personnel are in the detection scope, so can sense the signal, when personnel leave the back, microwave radar and infrared detection response module can not gather when personnel's signal, carry out the time delay after a period, judge that personnel are actually not in the field just to inform the system to carry out the operation that no personnel are in the field, just so the continuity of system operation has been kept, furthest reduces the production of false positive, laser projection display module has also been protected, prevent that it from constantly opening and closing.
Fig. 3 is a program flow chart of a higher-level computer, and specifically includes steps of also initializing to be a program starting point, acquiring at regular time J seconds since sampling of a lower computer is performed in a certain period and sampling is not necessarily too fast, after data is acquired, analyzing the data, turning on a projector if a person is on the spot, turning off projection if no person is on the spot, and enabling the system to enter a low-power sleep mode and only maintaining basic real-time detection so as to achieve the purpose of saving energy.
In addition, when the technology such as gesture control, an image collector and deep learning is deeply transformed, the laser projection display can also have master control controllability and can be displayed only within a preset time, and energy consumption is further saved.
The wireless radio frequency transceiver module and the wireless screen projection transceiver module are mature devices applied to the current communication technology, such as wireless radio frequency transceiver chips of CMT2380F32 and the like, and are relatively small in size and cost. The use of the communication finished product components and parts furthest provides convenience for system installation and avoids wiring troubles.
