Abstract

The invention relates to a node device and a control method of a wireless sensor network, and the node device comprises a power source, a sensor that collects data, a wireless radio frequency unit, a sensor interface unit, an intercepting unit that intercepts a time synchronizing frame from the network, a storage unit that temporally stores data, and a main control unit that cuts off the power source of the devices except the main control unit and leads the devices to rest when the time synchronizing frame is intercepted or after data is sent out, electrifies the sensor interface unit so as to implement data acquisition after reaching a preset time, and electrifies the wireless radio frequency unit and sends data to a management device after data acquisition is implemented for a plurality of times. The control method controls the node device to send data after the data acquisition is implemented for a plurality of times and to rest after a preset time. When the node device is applied into farmland information collecting, the node device saves power sources due to low power consumption mechanism, prolongs service life, and realizes synchronous resting and waking of all nodes in the sensor network.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to wireless sensor network node equipment and a control method suitable for farmland information collection. Background technique [0002] Precision agriculture is one of the hot fields of agricultural science research in the world in recent years. The meaning of precision agriculture is to finely and accurately adjust soil and crop management measures according to the specific conditions of each operating unit in the field, and to maximize the optimization of various agricultural inputs in order to obtain the highest yield and maximum economic benefits, while protecting the agricultural ecological environment and protecting the agricultural environment. Agricultural natural resources such as land. Precision agriculture is an organic combination of existing agricultural production measures and newly developed high-tech. At present, precision agriculture is mainly ...
