Friends who are reading this article at this moment, if the coordinates are near Beijing and North China, may you look at the window? What mood?
On the 19th, the Central Meteorological Observatory continued to issue an orange warning. As of today, the country has a heavy impact area of ​​580,000 square kilometers, reaching the most extensive, longest, and strongest embarrassing process this year. The smog and the smog, can't stop for a while, wait until 2017, let's make another appointment?
While dressing up like a biohazard every day, I found such a problem: wearing a mask while driving is inconvenient and overly cute, and there are a lot of bugs in the car air purifier and the pm2.5 filter. And after all, the car is sitting in an old and small, so the smog and other air pollution can not be ignored in the driving scene.
There is an opportunity for demand, and the air inside the car may be a huge entrepreneurial opportunity, or more explicit: life-saving industry. In general, the traditional model of this field is full of problems, and the existing technological solutions have yet to be boldly revolutionized and quickly improved.
In fact, car companies have long noticed the problem of air inside the car. Whether it is a new filter against PM2.5 or a car air purifier with a lot of price, there are already many car companies and startup teams doing it. But as far as the current popular technical solutions are concerned, the overall problem is still very much:
1. Instantaneous pollution problems when opening the window. Be aware that the instantaneous soaking ability of the haze is very strong. The PM2.5 can be filled with the entire car in the instant of opening the window. Moreover, the opening and closing rate of the door window during daily driving is quite high, which also causes the effect of purifying the air in the air filter and the like is not good, and the coverage of the filtering device based on the air inlet and outlet is also very limited.
2, air purification dead angle problem. At present, the air outlets of various car air purifiers are all oriented, and the devices such as seats in the car cause many possible dead angles in the flow of clean air. Even with air quality testing, there are several levels of air quality in a car.
3. High-speed pollution problems. As a car that has been exposed to strange air pollution sources such as smog and exhaust gas for a long time, the air pollution rate is quite high. The general high-quality air filter and car air purifier filter materials can not be polluted or blocked by the air outlet for a long time. For the average home user, it is almost impossible to change the air filter frequently.
From these points of view, there are a large number of comprehensive problems in the current air purification devices for mainstream models and external distribution markets. In the future, this field needs to be upgraded to meet the general needs of the “Suizhong peopleâ€. There may be several solutions:
What are the current "small car rescue black technology"?First, the super large filter
One idea is to still think of ways on the filter. It is only different from the filter size and material of the traditional car, and it adopts the filter setting of super protection level.
This kind of thinking sounds simple and rude and has no technical content, but it is the method that Musk uses on Tesla. The oversized HEPA filters used by Model X and Model S are not only domineering in appearance, but have also proven to be resistant to military-grade biochemical attacks in various experiments. The internal circulation system on the external full-sealed frame is certainly much safer, but it is still difficult to solve the air pollution contact brought by the frequent switches, and in fact the pollution of the haze is not so serious, how much equipment against chemical weapons A little bit of "cannon to fight mosquitoes" the color of the show.
But in any case, the future car has definitely adopted the super-filter is also a fact of nailing, just to combine something smarter.
Second, intelligent detection and purification control system
The Chinese and American Internet industries generally believe that the commercial revolution of AI is about to come in 2017, and it is naturally the case in the pioneering field of the Internet of Things, especially the core proposition of health.
An idea of ​​using AI to solve air pollution in a car is to place an air environment monitoring device at various positions of the car, and use artificial intelligence and deep learning technology to analyze the air purification needs of each position, and adjust the starting surface through artificial intelligence. The car air purification system performs real-time airless air improvement.
This kind of solution is not too difficult to meet technically. What is needed is the integrated depth of monitoring and new strip street system, and the depth of adaptation with the car AI. Since the demand for air purification in vehicles in North America and Europe is not obvious, the air monitoring and purification of AI+ vehicles has not become the main proposition of the Internet in the United States. However, such technology is very suitable for the hard-hit areas such as China and India, and China's Internet car companies may have great opportunities. Corresponding monitoring components, purification components, and operating systems also have opportunities.
Third, the vehicle air purification system
Similar to the previous idea, some people have proposed a way to configure the vehicle air purification system and connect the vehicle intelligent system. However, unlike artificial intelligence-controlled air purification, the vehicle air purification system can be deeply connected with energy, power and other systems, and completely hidden into the vehicle as a whole, without occupying the external space of the vehicle. And the vehicle has no dead angle effect, and the effect can be clearly projected onto the vehicle terminal.
But this technology also requires that the car must be a new energy car like Tesla, so that there is room for a comprehensive purification system. In addition, this must allow car companies to consider smart air purification when designing models.
Fourth, negative oxygen ion + ultraviolet sterilization
The other way is more radical than air purification. It is the release of sterilizing gas or light from the vehicle's equipment, which kills or offsets the air pollution when it enters the car. This is against the pollution of the internal circulation system and the long-term use of pollutants to corrode the air purification equipment. problem.
Today, Volvo and other models already have application-grade devices for anaerobic ion sterilization. However, in many "black technology" scenarios, negative oxygen ions are released as a hedge gas for driving doors and windows, and harmful gases at close range of the vehicle are killed to avoid the damage caused by instantaneous pollution.
In combination with this, it is to solve the pollution problem of the car in the non-driving and unmanned state. The vehicle itself emits strong germicidal rays such as ultraviolet rays, and is sterilized and disinfected at a time in an unmanned state in the vehicle to resist the adhesion of long-term air pollution.
The technical difficulty of the corresponding equipment is still very high. If it can really appear in the commercial version, it can be said that it is absolutely "black technology".
5. Intelligent regulation of internal and external circulation
Taking a step back, there is also a relatively simple artificial intelligence solution to the air pollution program, which is not to place new equipment on the air filtration and monitoring side, but to make a small upgrade according to the existing internal and external circulation system of the vehicle. Use artificial intelligence to automatically monitor when and where to perform air filtration and circulation scenarios.
The characteristic of this method is that it is not costly, and the adaptability is very high. Many relatively old models can also be upgraded. The intelligent switching and efficient filtering of internal and external circulation can solve most air pollution problems. However, the problem of this kind of scheme is still obvious: when there is serious pollution everywhere, the efficiency is not high, and the dead angle still exists.
ConclusionTo be honest, the haze is bound to be a long-term survival. This is the price of developing and neglecting the environment. The debt period is always longer than the human imagination, and it is also suffering.
So instead of cursing the environment and looking forward to the north wind, it is better to think about it. If black technology is black, it is still very popular. Especially according to this year's trend, the scope of smog is spreading rapidly. In other words, the "smog economy" of the radiation circle is also growing rapidly.
