Automotive electronics is the general term for electronic control devices for car bodies and electronic control devices for car vehicles. Vehicle body electronic control device, including engine control system, chassis control system and body electronic control system (body electronic ECU). The most important role of automotive electronics is to improve the safety, comfort, economy and entertainment of the car. Electronic control system consisting of sensors, microprocessors MPU, actuators, dozens or even hundreds of electronic components and their components

Photovoltaic energy systems typically include solar cells or components, charge and discharge control systems (or inverters), and load control. Solar cells are devices that convert solar radiant energy into electrical energy based on the principle of photovoltaic effect. Affected by weather, load and other factors, solar cells are not easy to obtain a stable DC output. Therefore, most solar energy systems need to first store energy through the battery and then supply power to the outside. The main function of the charge and discharge controller is to control the charging and discharging process of the battery in the system to prevent the battery from being damaged due to overcharging or overdischarging. The function of the inverter is to convert the low-voltage direct current output from the battery into the alternating current required by the electric appliance.

The high-frequency power supply equipment (communication power supply) system can be combined according to the system capacity rectification module, the modules are automatically balanced, and the modules can be replaced online. The system high-frequency switching power supply (communication power supply) system can select multiple rectifier modules according to the system capacity. The module automatically divides the current, and the module can be replaced online, and the system capacity is convenient to expand. The monitoring module can reliably realize the intelligent management of the power system and the battery, and is equipped with a modem, and can also perform centralized remote monitoring through a public or private telephone network.

The lighting project also includes research and manufacturing of light sources, lamps and control systems, measurement of luminosity and chromaticity, and visual evaluation. In particular, the basic theory of modern lighting, the measurement of light, electric light sources, lighting fixtures, lighting procedures and standards, as well as qualitative analysis and basic quantitative calculation of various light sources and lighting technologies.

Household appliances (HEA) mainly refer to various electrical and electronic appliances used in homes and similar places. Also known as civil appliances, household appliances. Household appliances have liberated people from heavy, trivial and time-consuming housework, creating a more comfortable and beautiful living and working environment for human beings, providing rich and colorful cultural and entertainment conditions and becoming a modern family. Necessities of life.

The basic conditions for medical equipment to continuously improve the level of medical science and technology are also important signs of modernization. Medical equipment has become an important field of modern medical care. The development of medical care depends to a large extent on the development of the instrument, and even in the development of the medical industry, its breakthrough bottleneck has also played a decisive role.

Military products have the characteristics of cutting-edge technology, high product quality requirements, small batches, and many varieties. From the processing of parts to the final assembly into products, the processing technology includes machining process, special process, electronic assembly process, and precision mechanical assembly process. Wait, there are many production links and the production process is complicated.
