Abstract

The invention discloses a control method of a low-power-consumption wireless sensor network system. The control method includes the following steps: a communication cycle Tcom based on time-triggered scheduling is set, communication is initiated at a moment point of any integer multiple of Tcom; Ts is a system program execution cycle, and serves as a system awakening cycle at the same time, at a moment of any integer multiple of Ts, the system is awakened, and in a subsequent tm time slot, a system program task is executed, and sensing and data sampling processing are performed; and in a fixed-cycle communication time slot tp, transmission of sensing data and a diagnosis state is performed, and the cycle of the fixed cycle is larger than that of the system program execution cycle. The control method of the low-power-consumption wireless sensor network system has the advantages that on the basis of ensuring real-time performance of the system, a low-power-consumption mode is adopted as far as possible, the energy consumption of the system is greatly reduced, the life of a battery is prolonged, and applicability and usability of a wireless network measurement and control system is greatly improved.

Description

technical field [0001] The invention relates to the field of wireless sensor technology, in particular to a control method of a low-power wireless sensor network system. Background technique [0002] Among the existing technologies, informatization and intelligence have become an important development direction in the fields of rail transit, static transportation and industrial control, and wireless sensor networks are an important technical support for informatization and intelligence. In many applications, due to constraints such as power supply and wiring, it is not realistic to use a wired measurement and control system, which requires a wireless sensor network measurement and control system that does not require external power supply and wiring. The working life of such a condition monitoring and sensing system is limited by the life of the battery power supply. [0003] The wireless sensor network measurement and control system is mainly based on battery power supply,...
