Description

Remote wireless information acquisition control device

Technical Field

The invention relates to the field of wireless irrigation control, in particular to a remote wireless information acquisition control device.

Background

In the aspect of the existing agriculture, in order to ensure the growth and development of crops, the water-requiring condition of the crops needs to be monitored and irrigated in real time; in the aspect of urban landscaping, frequent irrigation of forest flowers and plants is also needed. In the modern agricultural irrigation technology, especially in some remote areas, when some large-area crops are irrigated, a large amount of manpower, material resources and financial resources are required to be invested, so that not only is limited resources wasted, but also the agricultural production cost is increased, and the agricultural production is contused

Most of the conventional GPRS wireless irrigation controller devices only support one-way control, at most two-way control, the functions are relatively single, the expansibility is poor, when the water pressure is insufficient or irrigation needs to be separately controlled in a classified mode, or when a plurality of irrigation control nodes or soil information acquisition points need to be deployed in the same area, due to the limitation of the number of control channels and wired control, the problem can be solved only by increasing the number of controllers, a large amount of cost is increased, and the market acceptance is low.

SUMMERY OF THE UTILITY MODEL

Current situation to above-mentioned prior art, the utility model aims to solve the technical problem that a long-range wireless information acquisition controlling means is provided, through increase 485 communication interface, control interface, multiplexing expansion interface and loRa module on the hardware, solved multi-functional diversified demands such as gardens intelligence timesharing classification irrigation, soil moisture content collection, water quality monitoring, meteorological monitoring to and the too high problem of a plurality of irrigation information acquisition node cost of local deployment.

In order to solve the technical problem, the utility model discloses the technical scheme who takes is: a remote wireless information acquisition control device comprises a micro-control unit, a communication module, a communication interface and a power supply, and is characterized by further comprising a low-power local area network wireless communication module and a standby expansion interface, wherein the number of the communication interfaces is greater than 1.

Preferably, the communication interface is 4 485 communication interfaces, and can independently control four-way electromagnetic valves or contactors.

Preferably, the standby extension interface includes, but is not limited to, general GPI0, I2C, TTL serial port, ADC, and other communication interfaces for accessing other non-use devices.

Preferably, the low-power local area network wireless communication module is set as a LoRa module, and is used for communicating with LoRa nodes in a coverage area and meeting the requirement of deploying a plurality of control and acquisition nodes in a local area.

Preferably, the power source includes, but is not limited to, a battery, a solar cell, or mains electricity.

Preferably, the communication module includes, but is not limited to, a GPRS module, a 3G module, and a 4G module, and is configured to receive data information of each sensor in the coverage area and send a command to control the relevant devices in the coverage area.

Preferably, the micro control unit is set as an STM32 low-power chip.

The utility model has the advantages that:

(1) through setting up 4 485 communication interface, can insert 31 way 485MODBUS sensor devices, but four ways solenoid valve of independent control or contactor, and need not to increase the quantity of controller again.

(2) The built-in LoRa module, bigger control range, more control nodes, it is more energy-conserving again.

(3) And a standby expansion interface is added, so that a user can conveniently access other non-use equipment.
