Since ancient times, frescoes have been used to decorate houses, and many high-privileged ministers have used them to demonstrate their personal status. Unlike modern mural paintings, ancient frescos are carved directly on the walls, while modern paintings are made on the wall. Invisible murals are a very popular form of frescoes in recent years. How is the invisible fresco charged? Next, Xiao Bian told everyone about the invisible mural charges and the design of invisible murals . First, how does the invisible mural charge? 1. The invisible mural is the use of various colors of paint, and draws a variety of patterns and patterns, such as animals, flowers, etc., by hand-painting. As for the price is mainly determined by the pigment, most of the invisible murals are non-toxic and odorless. The pigments, the pigments are made of special materials, so the price will be higher. Some fluorescent pigments are mostly between 100-180 yuan. Of course, this price range is limited to pigments with a weight of about 180 grams. 2. People who have mastered the technique of painting can make their own materials, but most people are responsible to the decoration company. The decoration company charges the mural according to the square meter, and the painting price per square meter. Will be affected by the use of materials and design patterns, the general price per square meter is more than one hundred yuan, and some well-known decoration company's price is even as high as thousands of yuan per square meter. The above price is for your reference only, the specific price suggested that you consult with the local decoration company. Second, the three major points in the design of invisible murals 1. The color and pattern of murals should be matched with the design style of the house. If your home is Chinese style decoration, you can choose traditional colors such as red, black and gold. Patterns can be selected with Chinese traditional patterns or patterns that are often found in Chinese painting. The modern decoration style house is more realistic in the fresco pattern, and the colors are relatively bright. 2. The design of the invisible mural is related to the location of the mural. It is recommended that you do not paint the entire room with frescoes. This will make the space look complicated. You can paint large-area frescoes on the walls of important locations in your home, which will give you a great visual impact. In addition, you can also draw murals in a space with special characteristics, such as drawing flowers and plants on a stairwell. 3. Invisible murals are not limited in their design style. They are not only suitable for use in homes but also are suitable in some public places. The common invisible murals include patterns, landscapes, cartoon characters, and plants. Different styles of murals have different visual effects. We can tell designers about their preferences and expectations. Xiao Bian summary: The above is the invisible mural is how to charge and design the invisible mural of the three main points of the relevant content, I believe we see here have some understanding of invisible murals. It's better to draw a hidden mural in your home. You can feel the cinematic atmosphere in your home and it is very interesting to think about it.
The vibration sensor(Vibration Transmitter) is one of the key components in the testing technology of Vibration Measurement. Its main function is to receive the mechanical quantity and convert it into a proportional electric quantity. Because it is also an electromechanical conversion device. So we sometimes call it a transducer, a vibration pickup, etc.
Commonly used vibration sensors are as follows:
1. Piezoelectric resonant
The piezoelectric sheet is used to receive the vibration signal, and the resonance frequency of the piezoelectric sheet is relatively high. In order to reduce the resonance frequency, it is realized by increasing the mass of the piezoelectric sheet vibrating body, and using a spring ball instead of an appendage to reduce the two resonance frequencies and enhance the vibration effect. Its advantages are high sensitivity and simple structure. However, the signal needs to be amplified and sent to a TTL circuit or a single-chip microcomputer circuit, but it is enough to use a triode single-stage amplification
2. mechanical vibration
In the traditional vibration detection method, after being vibrated, the spring ball vibrates at a reduced amplitude for a long time, and this vibration is easy to be detected by the detection circuit. The vibration output switch signal is determined by the output impedance and the resistance value of the matching output. According to the input impedance of the detection circuit, it can be made into a high-impedance output mode.
3. Micro Vibration Sensor
The mechanical vibration sensor is miniaturized, the vibration body is carbonized and sealed, and its working performance is more reliable. The output switching signal is directly connected with the TTL circuit and or the input circuit of the single-chip microcomputer, and the circuit structure is simple. The output impedance is high, and the quiescent working current is small.
Advantages of Vibration Sensors
1. Small size and light weight. It can be applied to some vibration test systems that are greatly affected by the additional mass.
2. It has a wider response frequency range of 4Hz-2000Hz than the magnetoelectric speed sensor, and the mechanical moving parts are not easy to damage
