Embodiment Construction

[0026] figure 2 A flow chart of the method in an embodiment is provided, including the following steps:

[0027] S1. Multiple Zigbee sensor nodes perform sparse sampling on crop growth environment information.

[0028] The data collected in this embodiment is temperature information, and the size of the data set is U=20, I=60, that is, there are 20 sensor nodes, and each node collects 60 times for one data recovery. Set the sampling rate f=0.2, and give the random sampling matrix E 20×60 , then the proportion of element 1 in the matrix is ​​20%.

[0029]

[0030] It is set to collect data every one minute, and it takes one hour to collect 60 times. Therefore, each data recovery is to recover the temperature data within one hour.

[0031] Sparse sample data A collected in a certain time 20×60 Such as image 3 As shown, it can be seen that the data set is sparse, only a small part of the real data collected, and the others are zero.

[0032] S2. The collected crop grow...

Abstract

The invention discloses a wireless sensor network (WSN) crop growth environment information sparse acquisition and transmission method based on NB-IoT and FPGA and applied to smart agriculture. The method mainly comprises the steps that crop growth environment information is collected in a sparse sampling mode through Zigbee wireless sensor nodes; the collected sparse data information is sent to an FPGA core control end, and a matrix filling algorithm is executed in the FPGA to fill the sparse data set matrix; data recovered to be complete is sent to the cloud platform end in the NB-IoT mannerand is displayed at the cloud end, so that the functions of collecting, transmitting and monitoring the crop growth environment information are finally realized. According to the invention, a sparsesampling theory is applied to the wireless sensor network, and a matrix filling algorithm is realized by hardware, so that lower power consumption of sensor nodes and higher data recovery speed can beensured.

Description

[0001] 【Technical field】 [0002] The present invention relates to the field of hardware acceleration and wireless sensor network algorithms, and more specifically, to a WSN crop growth environment information collection and transmission method based on NB-IoT and FPGA. [0003] 【Background technique】 [0004] At present, my country is a large agricultural production country, but it is not a strong agricultural production country. The main reason is that the level of agricultural modernization is lacking, and there is a big gap with developed countries. It still adopts the operation mode of relying on the sky, and lacks effective technical means to realize the intelligentization of agriculture. and unmanned management. [0005] With the development of my country's narrowband Internet of Things technology and the maturity of sensors and other technologies, the above problems can be effectively solved. The use of modern scientific and technological means to achieve the collection ...
