Abstract

The invention provides a wireless sensor network communication system, which comprises a sink node and at least one wireless sensor, and is characterized in that the sink node sends a wake-up signal to the wireless sensor, and the wake-up signal comprises address information of a sensor to be waken up; the wireless wake-up unit receives the wake-up signal, and if the address information in the wake-up signal is the same as the address information of the wireless sensor to which the wireless wake-up unit belongs, an interrupt signal is sent to the processor; the processor receives the interrupt signal, sends a starting signal to the communication unit, and activates the communication unit through the starting signal; the sink node sends data information to the wireless sensor; the communication unit receives the data information and sends feedback information to the sink node according to the data information, and the processor and the communication unit enter a dormant state. According to the wireless sensor network communication system provided by the invention, the service life of the wireless sensor is prolonged through the wake-up mechanism, and the wake-up signal contains the address information of the sensor to be waken up, so that the wireless sensor is accurately waken up.

Description

technical field [0001] The invention relates to the field of wireless sensor technology, in particular to a wireless sensor network communication system. Background technique [0002] With the development of energy transformation and electric power digitalization, the power grid has put forward higher requirements for the depth, breadth and density of information perception. The wireless sensor network has the advantages of massive connections and low cost. It is the most economical and convenient way to obtain basic data such as power grid operation, equipment status, and environment. It can effectively support the energy Internet and the digital and intelligent construction of the power grid. However, when the wireless sensor network is applied to the power grid, due to the difficulty in obtaining power in application scenarios such as substations and transmission lines, most sensor deployment environments do not have power supply conditions, and the requirements for power...
