Among the various modern high-end machinery and equipment, the importance of sensors is self-evident, whether it is in the automation industry or smart city construction, including the Internet of Things, intelligent transportation, robots, construction machinery, aerospace, military, etc. There are extremely important applications in various fields, and its development has also received people's attention.

Sensors are also called electrical features, which are the main devices for people to obtain various information in the fields of nature and production. With the vigorous development of my country's modernization, the sensing technology is changing with each passing day, and its application fields are becoming more and more extensive. Its position in the field of municipal fire protection is even more significant.

Automotive pressure sensors are usually used to measure the pressure of liquids and gases in vehicles, so they can be used in many vehicle systems. Segmented by application, the automotive pressure sensor market can be divided into transmission systems, engine control systems, power steering systems, heating, ventilation and air conditioning systems (HVAC), airbags, anti-lock braking systems (ABS) and direct tire pressure monitoring systems ( directTPMS). Engine control systems are expected to occupy the largest share of the automotive pressure sensor market. Automotive pressure sensors in engine control systems are often used in engines, fuel injection pumps, and exhaust. And ABS is expected to become the fastest growing application field in the automotive pressure sensor market. The main factor promoting the growth of this field is the regulations related to safety and safety performance. For example, India has mandated the installation of ABS in cars since 2018, and this regulation can promote the growth of the market for automotive pressure sensors.

The high-end equipment manufacturing industry such as construction machinery is an important basic pillar industry in my country, and it occupies an important position in the national economy. Hunan Province is a large and powerful province in the construction machinery industry, and its industrial scale ranks first in the country. The mechanical driving force of high-end equipment is mainly provided by the hydraulic system with large driving force, flexible control and long service life. Pressure-sensitive chips and sensors with high pressure resistance, long service life and high precision are the key elements for realizing precise and intelligent hydraulic control and ensuring safety. Device.

With the vigorous development of rail transit and frequent safety accidents during the construction process, an intelligent monitoring system for rail transit based on wireless sensor network is designed. For data information, the wireless network is used to transmit the data information to the monitoring platform, so that managers can understand the construction information in real time from a distance, and effectively ensure the safe progress of the construction.
