Internet of Things signal anti-interference transmission system for breeding

Abstract

The invention discloses an Internet of Things signal anti-interference transmission system for breeding. The Internet of Things signal anti-interference transmission system is characterized by comprising a signal processing module, a data processing unit and a protocol processing unit which are connected in sequence, wherein the signal processing module is used for reading analogue quantity signals or communication protocols with different types, which are input by each agricultural environment sensor, carrying out digital-to-analogue conversion or communication protocol conversion and then transmitting converted digital quantity information to the data processing unit; the data processing unit is used for carrying out algorithm transformation on the received digital quantity information.According to the Internet of Things signal anti-interference transmission system for breeding, the wire arrangement cost and the post-period maintenance coat can be greatly reduced; furthermore, the deployment cost and difficulty are simplified and a lightning stroke problem is avoided; therefore, the Internet of Things signal anti-interference transmission system has very good operability and practicability, and an application level of an agricultural Internet of Things sensor can be improved.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an anti-interference transmission system for signals of the Internet of Things for farming. Background technique [0002] In the current farming industry, it is increasingly common to use the Internet of Things to collect various key sensor data in the animal growth environment in real time. In different environmental control systems, it is generally required to use dedicated sensor devices. If you want to replace or increase the sensor peripherals of the environmental control system, you often need to modify the control system hardware and software itself, which is costly and takes a long time, and the implementation is not flexible. The environmental data collection of the Internet of Things in the breeding process generally uses physical or chemical sensing elements for various characteristics to transform the perceived environmental index change information in...

Problems solved by technology

The main problems of the existing farming IoT sensor application mode are as follows: 1. The access formats are diverse and the data interface is not uniform, which requires high customization of the environmental controller and is not easy to expand in the future; the environmental controller must be based on its own hardware structure To customize and use these sensors with the communication protocol, it is necessary to clarify the type, quantity and hardware processing circuit of the sensor connection when the product is finalized, and it is difficult to make flexible changes and expansions in the future; 2. The sensor deployment method generally uses analog signals Direct connection, the site construction specifications and wire standards are high, the communication distance is short, and the anti-interference is poor; the current mainstream agricultural environmental sensors generally directly convert the original analog signal, or through the processing circuit, forward the custom Digital signal in communication format; 3. The sensor device is directly connected to the environmental controller, and there is no electrical isolation and necessary lightning protection measures in the middle, which will easily lead to lightning strikes entering the controller circuit from the line, resulting in greater equipment loss
