Problems solved by technology

In addition, in the current soil moisture guidance irrigation system, when querying soil moisture information, the concern is not the difference between 45.33% and 45.44%, but the difference between 45% and 30%, and use this to get the 30% point soil low humidity
The sensing accuracy error of the current soil moisture sensor is about 4%, which determines that the transmission of high-precision soil moisture information does not make much sense

Embodiment 1

[0051] This embodiment specifically describes a soil moisture sensor network system provided by the present invention, figure 1 It is a structural block diagram of the system of the present invention, the system includes soil moisture sensing equipment, data collection equipment, data remote transmission equipment and system management equipment; the data collection equipment consists of a soil moisture sensor not connected to the soil moisture sensor on hardware Sensing equipment is realized. The data remote transmission equipment is designed and implemented based on BenQ's M23G GPRS modulation module, and exchanges data with the data collection equipment through the RS232 serial interface.

[0052] The power of data collection equipment and data remote transmission equipment is supplied by solar power system. The data collection equipment, data remote transmission equipment and solar power supply system together form the field gateway equipment.

[0053] The soil moisture ...

Embodiment 2

[0061] This embodiment specifically describes a method for obtaining soil moisture information provided by the present invention using the system provided in Embodiment 1, and the method includes the following steps:

[0062] Step 1: divide the soil moisture value into different gradient intervals, and number the different gradient intervals;

[0063] The gradient interval can be adjusted through the system management equipment according to specific application needs;

[0064] When the accuracy of the soil moisture value is low in the application, the gradient interval can be adjusted larger; when the accuracy is required to be higher, the gradient interval can be adjusted smaller;

[0065] When the monitoring accuracy of the soil moisture sensor connected to the soil moisture sensing device is high, the gradient interval can be adjusted to be small; when the monitoring accuracy is low, the gradient interval can be adjusted to be large.

[0066] After the soil moisture sensin...

Abstract

The invention relates to a soil humidity sensor network system and a method for acquiring soil humidity information, which belong to the technical field of wireless sensor networks. In order to realize the effective acquisition of the soil humidity information in farm fields, the invention provides a soil humidity sensor network system based on interval adjustment, which comprises soil humidity sensing equipment, data collection equipment, data teletransmission equipment and system management equipment. After the system and the method are adopted, the network size can be enlarged effectively and transmission data can be pressed effectively according to application requirements and the sensing accuracy of an external sensor, so unnecessary resource waste is avoided and the optimization of the sensor networks is realized based on application. The practical application proves that the system and the method can cooperate with an irrigation system better to achieve the good effect of automatic irrigation.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a soil moisture sensor network system and a soil moisture information acquisition method. Background technique [0002] Precision agriculture is one of the hot fields of agricultural scientific research in the world in recent years. It is an organic combination of existing agricultural production measures and newly developed high-tech. Adjust soil and crop management measures to maximize the optimization of various agricultural inputs to obtain the highest yield and maximum economic benefits; at the same time protect the agricultural ecological environment and protect agricultural natural resources such as land. At present, precision agriculture is mainly carried out from two aspects, one is precision agriculture based on sensor technology; the other is based on geographic information system (Geographic Information System, GIS), Global Positioning System (Global ...
