An agricultural environment information collection and control device

Abstract

The invention relates to an agricultural environment information acquisition control device. The device comprises a control circuit and a sensor interface circuit which are electrically connected with each other. The control circuit comprises an STM32F107 microprocessor U1 and a shifting register U16. A pin 23 of the microprocessor U1 is connected with a wake-up circuit. The wake-up circuit comprises a resistor R3, a capacitor C6 and a switch K1. The pin 23 of the microprocessor U1 is further connected with one end of the resistor R3, one end of the capacitor C6 and one end of the switch K1, the other end of the resistor R3 is connected with a power supply, and the other end of the switch K1 and the other end of the capacitor C6 are grounded. The shifting register U16 is electrically connected with the sensor interface circuit. Environmental parameters of an agricultural site can be monitored in real time through the device; the device has wireless access to the Internet and is convenient and flexible to use; by the adoption of distributed management of sensor nodes, various sensors can be freely combined, and therefore the system flexibility is improved; all sensor node power supplies are independently controlled, and therefore the system power consumption can be effectively reduced and the requirement for working in the field for a long time can be met.

Description

technical field [0001] The invention relates to an agricultural environment information acquisition control device, which belongs to the field of agricultural technology. Background technique [0002] Agricultural environment refers to the totality of various natural and artificially modified natural factors for the survival and development of agricultural organisms. Agricultural environmental monitoring is to monitor the environmental parameters of agricultural sites by physical and chemical means. For a long time, agricultural production has adopted extensive management, making judgments on the crop environment based on the experience of producers, and then taking corresponding measures. With the development trend of precision agriculture, more and more attention is paid to the collection of environmental information, and sensors such as soil temperature, soil humidity, and light have been used, but the manual discrete collection method is still the main method, and the wo...
