Future home intelligence Future homes may have many home appliances connected to a central device that provides overall control through a home network bus. The construction of this so-called “smart home” involves technology, standards, installation, and maintenance. work.
When people's homes are automated, various electronic devices can operate without much need for intervention. For example, automated lights and CD players can be turned on at pre-set times (such as when the owner returns home), while automated heating/cooling systems can adjust the room temperature when someone enters or exits. In fact, the day-to-day arrangements of any electrical/electronic device and individual can be automated, so that people can spend less time dealing with trivial matters at home and put more time on important issues and improve the quality of life.
The high-end intelligentization of hardware locks is the mainstream With the changes in market trends in recent years, intelligence, environmental protection, and energy saving have become new consumer concepts. Insiders said: “From the perspective of market trends in recent years, smart and environmental protection, energy saving The hardware products are getting more and more popular among consumers.China's high-end hardware products have a huge market space, and the growth trend of top-level products is particularly obvious.Users have also extended from the top international five-star hotels to the high-end residential houses project."
On the one hand, high-end locks have a high technological content, and they are more human-oriented and personalized. They are sought after by consumers. On the other hand, products with high technological content have higher profits, and businesses are naturally optimistic. Many companies in locks are deeply aware that only by increasing the technological content of products, upgrading product quality, and increasing the added value of products can they gain a foothold in this market.
At present, smart locks with high technological content, including password locks, IC card locks, and fingerprint locks, have gradually won the recognition of high-end consumers due to their unique convenience and gradual maturity of technology; Fingerprint locks have even broader market prospects due to their uniqueness, non-replicability, portability, forgetfulness, and loss-free features.

1. Do not blindly use power-consuming equipment. Please use the power-consumption equipment according to actual needs, and do not use it blindly to increase fuel consumption. Rear window heaters, auxiliary headlights, blowers and air-conditioning systems all have a large amount of electricity, which increases generator load and improves fuel consumption. For example, if the rear window heater is used for 10 hours, the overall vehicle fuel consumption will increase by 1.0 liter.
2. Choose fair pasغير مجاز مي باشدes. In all engine operating conditions, low speed and heavy load are the most fuel-efficient. When driving on urban roads, cars are often crowded and often require starting parking, which consumes a lot of fuel. Therefore, before each trip, drivers should formulate a good driving plan to understand the situation of the roads they have passed, and try to avoid rushing through busy roads during traffic peak hours so as to avoid traffic jams and fuel and time. Even if you are driving on a section of road that you know, you should always listen to traffic reports on the traffic station to understand the latest traffic information and keep the traffic smooth.
3, accurate refueling. Refueling a car is not a matter of raising the label. The higher the product model is, the better the product will be. If the product model is too high or too low, it will result in insufficient combustion. Instead, the fuel consumption will be high, and even the engine will not function smoothly. This will severely damage the engine. Ideas and other important parts. In addition, if convenient, do not add too much fuel, increasing the car's own weight, will increase fuel consumption, timing of refueling in the early hours, the oil quality is relatively good.
4, to maintain normal tire pressure levels. Lack of tire pressure, dynamic resistance will greatly increase, tire shift or excessive wear may also increase fuel consumption. Therefore, it is advisable to check the tire pressure once a month and change the tires as needed. In addition, radial tires are used, which are 6% to 8% higher than ordinary bias tires.
5, accurate shifts. Do not run the engine at an unnecessarily high speed while driving. It should be hung as high as possible. Only when the engine is running unsuccessfully, hang it into the low gear. When a car equipped with an automatic transmission is accelerating, the accelerator pedal should be slowly decelerated, and the gearbox should be selected for an economic shift program, which should be advanced into a high gear and lagged into a low gear in order to reduce fuel consumption. When parking or decelerating, use the inertia of the vehicle as much as possible to achieve the purpose of fuel economy.
6. Maintain proper driving speed. Each vehicle has its own economic speed, and it is the most fuel-efficient to maintain the economic speed around the hourly speed. In general, the car is the most fuel-efficient when the speed is 70 to 90 kilometers. When the speed is high, the car's resistance is greatly increased. According to statistics, the speed increases to 110 to 120 kilometers per hour will increase by 25%.
7. Keep the vehicle low wind resistance. At high speeds, a large part of the power is used to overcome wind resistance. Therefore, try not to load on the roof or make unfair modifications. It is estimated that adding a luggage rack on the roof will increase fuel consumption by 5%. In the high-speed state, do not think that opening the window will be more fuel-efficient than opening the air-conditioner. Opening the window will greatly increase air resistance, and it will be even more غير مجاز مي باشدtly. Should clean up unnecessary things in the car, reduce the weight of the car.
8, as far as possible to avoid emergency hurry up. The soft, smooth driving style is the most fuel-efficient. In the initial stage, you should avoid slamming the gas pedal as far as possible. The exact method is smooth acceleration. After reaching a certain speed, you should keep driving as evenly as possible. When driving on a crowded road, you must also look at the road ahead to avoid sudden braking. This not only saves fuel but also extends the life of the vehicle.
9, to avoid the engine idle for a long time. The fuel consumption of idle engine speed at idle is far longer than normal driving. Therefore, it is better to turn off the engine when parking for a long time. For example, it is better to turn off the engine when parking. In the cold start, the temperature should not exceed 1 minute, and keep for a few minutes at low speed. You can.
10, to strengthen the maintenance of the car. The adjustment and maintenance of the car affected the engine performance and car resistance. According to statistics, the fuel consumption of the poorly maintained engine will increase by 10% to 20%. The owner of the vehicle shall make regular maintenance to the auto repair factory, such as checking the tire pressure, four-wheel alignment, adjusting the brake friction plate and the brake drum clearance, and oiling the lubrication points on the chassis of the car, changing the oil regularly, and inspecting the filters. In addition, the oil in the model specified in the bill, choose the smallest visغير مجاز مي باشدity, because the greater the visغير مجاز مي باشدity, the greater the friction and increase fuel consumption.

As an advertising media carrier, LED display is reported to account for more than 60% of advertising in 2015. With the current booming commercial development, more and more attention has been paid to it. However, LED display screens have developed over the past 20 years. Currently, there are still some technical details that have not been resolved. The phenomenon of display patches is one of them.
The back side of the LED module mask is flat, and because of the problem of the light type in front, the stripe-shaped protrusion and the brim of the lamp are designed. That is, the design focus of our design should consider the previous light pattern. It is precisely because of our design, and the shrinkage of the PC material is not fully considered, resulting in the uneven distribution of the surface stress caused by the shrinkage of the material, the stripe protrusion in front of the mask shrinks more than the back plane shrinks. Similarly, the stress generated in the front is larger than the later stress, and the imbalance between the front and rear of the stress causes the mask to غير مجاز مي باشد backward.
Because the stress distribution before and after the mask caused by material shrinkage and design defects is unbalanced, and the surface stress of the mask is unevenly distributed, the stress generated by shrinkage in the middle part of the mask is larger than the edge, so the mask is generally in the middle. More concave back. Some people may say that the mask is soft. I use the bottom case of the module to raise the middle of the mask. Should this phenomenon disappear? It can be concluded that there is no other phenomenon. Due to the shrinkage of the material, the curvature of the mask surface has an effect on the curvature of light reflection, so that the feeling of the plaque on the display screen is increased visually.
It can be seen that the display plaque is caused by the mask material and design defects, then how to solve it?
First of all, we must appropriately increase the thickness of the mask so that the shrinkage stress caused by the protrusion of the front of the mask can reach a negligible level. This solution can be solved, but the first solution is to accurately calculate the thickness of the mask mask.
