Problems solved by technology

However, each sensor has a special shell, which is connected to the computer through a wired method, which is too large to carry
[0003] Some research institutions and universities have also developed some targeted research on wireless sensor networks, but only a small part can meet the requirements of real-time measurement in the field
And even this small part of the detection instruments that can be measured on-site has a complex structure, large volume and weight, and is forwarded to the host computer through the information gathering point fixed in the field.
Since most sensors use a timing sleep mechanism, it is not convenient for users to collect abnormal point information in real time on demand.

Abstract

The invention provides a farmland wireless sensor network based on ZigBee. The network comprises a ZigBee coordinator, a wireless sensor node and a sensor, wherein the coordinator is connected with the sensor node in a wireless manner; the sensor node has a fixed node address; and the coordinator controls the on and off of a sensor power supply through the sensor node. The farmland wireless sensor network provided by the invention is characterized in that the network has a large quantity of data and is simple, flexible, stable and reliable; and the normal operation of the network can be maintained for longer time under a certain sensor power supply.

Description

technical field [0001] The invention belongs to the technical field of wireless sensing, and in particular relates to a farmland wireless sensor network and a data collection method thereof. Background technique [0002] Real-time monitoring of farmland information is the basis of precision agriculture and is of great significance to farmland management. With the development of agricultural informatization, the real-time perception and collection of precise farmland data has become the key to the success or failure of agricultural information systems. For the particularity of farmland data collection and processing, the combination of wireless technology and sensor technology is an ideal solution. At present, the multi-sensor data information collection instruments used in agriculture include PM111 plant physiological and ecological monitor, which can detect crop information and information such as soil moisture, temperature, and environmental temperature and humidity. How...
