3 thoughts on “The employment prospects of the weak electricity industry?”

Weak electricity contains many detailed categories, such as security monitoring, building intelligence, smart home, road monitoring, etc., even the communication industry you are currently engaged in, and some branch projects are also the category of weak electricity. So the employment prospects of the weak electricity industry are very good, and if your skills reach a certain level, you can become the chief of the project. It weak power engineering is a classification of power applications. The power application of electricity can be divided into two types: strong and weak electricity according to the strength of the power transmission power. Building and building groups generally refer to weak electricity below 220V50Hz. Mainly provide people with electricity and energy, and converts electrical energy to other energy sources, such as air -conditioning power, lighting electricity, power electricity, and so on.

very nice. Nowadays, in terms of weak electricity engineering, the development scope is extremely wide. The areas involved in technology include networks, communication, sensing, self -control, electronics and other aspects. Because of their high technical level, the design is very precise, so the design is very precise, so the design is very precise, so the design is very precise, so the design is very precise. The development of weak electricity technology in my country is very late, and many theories are still in the initial stage, only in a state of practice. At the same time, many places in my country have a fixed system in design. However, in the country, the industry's technical standards are not uniform, so many technical standards are uneven, which will cause many problems. It intelligent and weak electricity has developed to this day. Because there is no unified technical standard, there is no way to form a scientific and unified management model in terms of talent training. Designers have lack of professional knowledge. Due to the widespread scope involved in the intelligent and weak electricity industry, the comprehensive personnel of various majors lack high -level talents, and such problems are very common.
In fact, the weak electricity is promising, but most of them can be installed and debugged by comprehensive wiring and front -end equipment. It is not possible to install, debug and connect to the back -end computer room equipment.
