Description

technical field [0001] The invention relates to a wireless sensor network control terminal, in particular to a wireless sensor network control terminal based on soft PLC technology. Background technique [0002] After a long period of development, the traditional PLC technology has become a mature technology. Because of its high speed, high performance and high reliability, it has been widely used in the field of industrial control. However, the traditional PLC itself has many shortcomings. [0003] The products of traditional PLC manufacturers are complementary and compatible, and there is obviously a lack of clear and consistent standards, so it is difficult to build an open hardware architecture; the programming methods of each manufacturer's products are very different, and the technology is very proprietary. It takes a long time for professional training to master the programming method of a certain product; traditional PLC manufacturers are monopolized by several manuf...

Problems solved by technology

[0006] On the other hand, in the sensor network control system, the difference in detection area range and node density results in different network scales, node failure, new node addition and node movement, etc., which will make the network topology change dynamically. The network control system is required to have strong scalability and be able to adapt to changes in the network structure. The existing sensor network is usually implemented by an embedded controller 1, which has poor scalability.
