Problems and development trend of Appliance Switches market

The strategic goal is 2020. With sensors, elastic components, optical components, dedicated circuit as the key object, sensor and meter components field should strive to achieve the three strategic objectives: in industrial control, automotive, communications, environmental protection for the key service areas. Develop original technology and products with independent intellectual property rights; 2 based on the MEMS technology, based on integration, intelligence and network technology, strengthen the manufacturing process and the development of new sensors and instrumentation components, to leading products and close to the advanced level of similar foreign products; In order to increase the variety, improve the quality and economic efficiency, and accelerate the industrialization, the domestic sensors and meter components are up to 70% - 80% of the high-end products are up to 60%.

With a microprocessor. The combination of sensor integration and microprocessor. The general intelligent robot's sensory system consists of multiple sensors, capable of collecting, processing and exchanging information. The information collected needs to be processed by computer, and the use of Appliance Switches can be used to disperse information and reduce costs. Compared with the general sensor, the Appliance Switches has the following three advantages: the software technology can realize the high precision information acquisition, and the cost is low; Have certain programming automation ability; Versatility.

The manufacturing basis of Appliance Switches is micromachining technology. Different encapsulation techniques are used to encapsulate and process silicon in mechanical, chemical and welding processes. In recent years, a LIGA process has been developed (deep X-ray lithographic electroplating and sensitive film) for the manufacture of sensors. Electrical switches are usually very real-time, especially dynamic measurements that require data collection, calculation, processing and output in a few microseconds. A series of functions of electrical switches are supported by programs. If the function, basic performance, easy to use, and reliable work, mostly depend on software design and its quality, these software mainly have five categories. Including scale conversion, digital zero, nonlinear compensation, temperature compensation, digital filtering technology.

The research of Appliance Switches is mainly concentrated in professional institutes and universities. In the late 1980s, the results were reported. In the early 1990s, it started in the mid-1980s. Several domestic research institutions using hybrid integrated technology successfully developed a practical Appliance Switches, indicates that the study of the Appliance Switches of our country has entered the international ranks, but compared with foreign advanced technology, there are large gaps. According to Honeywel industrial measurement and control of product manager TomGriffith definition: a good electrical switch driven by microprocessor sensors and instruments' suits, and communication and on-board diagnosis and for monitoring and control system and/or operators to provide relevant information, in order to improve the work efficiency and reduce maintenance costs. Appliance Switches integrated with sensor, intelligent instrument all functions and part of control function, has the very high linearity and low temperature drift, reduce the complexity of the system and simplifies the system structure.

Appliance Switches have been widely used in various fields such as aerospace, aviation, defense, science and technology and industrial and agricultural production. For example. The Appliance Switches makes the robot have the five senses and the brain function, and the robot field has a wide application prospect. Can perceive various phenomena, complete various movements. But compared with foreign countries of sensors and instrumentation components product varieties and quality level, still cannot meet the needs of the domestic market, the level of the overall level is still in the abroad in the early 1990 s. Main problems are: scientific and technological innovation is poor, the core technology of manufacturing seriously lags behind foreign countries, with independent intellectual property rights of products, variety is not complete, the product technology level and foreign 15 years or so. The investment intensity is low, the research equipment and production process equipment lag, the result level is low, the product quality is poor. The disconnection between science and technology and production affects the transformation of scientific research results. The comprehensive strength is low and the industrial development is insufficient.
