A kind of agricultural environment information collection and control device with wireless interface circuit

Abstract

The invention relates to an agricultural environment information collection and control device with a wireless interface circuit. The device comprises a control circuit, the wireless interface circuit, and a GPS and GPRS communication interface circuit which are all electrically connected, and a wireless sending interface circuit is connected with a 433 MHz wireless transmitting module and used for sending an instruction to wireless sensor nodes; a wireless receiving interface circuit is connected with a 315 MHz wireless receiving module, and a soil moisture sensor interface circuit is adopted for being connected with a TDR-3 type soil water sensor to detect soil moisture in the position close to the collection and control device; the wireless interface circuit is adopted in the position far away from the collection and control device to be connected with the wireless transmitting module and the wireless receiving module, the wireless transmitting module and the wireless receiving module are connected with the soil moisture sensor to detect the soil moisture, the frequency of the wireless transmitting module is different from the frequency of the wireless receiving module, and interference caused between transmitting and receiving of wireless signals is avoided.

Description

technical field [0001] The invention relates to an agricultural environment information collection control device with a wireless interface circuit, belonging 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 stil...

Problems solved by technology

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 workload is heavy, and real-time and long-term monitoring is not possible. Making judgments about the agricultural environment
