Abstract
Description
technical field
[0001] The invention relates to the technical field of agricultural production, in particular to a neural network-based large greenhouse PD control system and method. Background technique
[0002] With the development of the economy, people's living standards are getting higher and higher. Compared with ordinary seasonal fruits and vegetables, off-season fruits and vegetables are more popular. However, this kind of off-season products need to be very strict when planting Environmental conditions such as intensity of care, temperature, humidity, etc., people have been able to use intelligent control methods, and after training the system, they can simulate the intelligent control of the greenhouse system by humans. In the case of greatly reducing the labor force, You can also harvest more products. The traditional control method belongs to the posterior control method, the response time of the control is long and it belongs to the remedial control method. Amo...
Examples
Embodiment 1
[0069] Large-scale greenhouse PD control system based on neural network, such as figure 1 As shown, it includes acquisition terminal, user terminal, environmental regulation equipment and server, and the server includes a storage module, an error feedback module, a control parameter analysis module and a PD control module, wherein:
[0070] The acquisition terminal includes a data acquisition control module and several sensor groups arranged in the greenhouse. The sensor groups are networked through nodes, and the sensor groups are used to collect the care intensity, temperature and humidity of the greenhouse.
[0071] The data acquisition control module is used to control the sensor group to collect the internal environmental information of the greenhouse in time sequence, and the internal environmental information includes the light intensity, temperature and humidity in the greenhouse;
[0072] The user terminal is used to send the crop information of the crops planted in t...
Embodiment 2
[0103] The difference with Embodiment 1 is that: if figure 2 As shown, it also includes a blowing device arranged in the greenhouse, the wind blown by the blowing device is hot air, and the server also includes a wind control module, a pest detection module, a pest analysis module and an image acquisition control module; the acquisition terminal also includes a positioning module and A camera installed in the greenhouse;
[0104] The collection terminal is also used to collect the external environmental information of the greenhouse, which includes the light intensity, temperature and humidity outside the greenhouse;
[0105]The positioning module is used to collect the location information of farmers entering the greenhouse, and send the collected location information to the server. Specifically, the positioning module includes a Bluetooth beacon and a Bluetooth gateway laid in the greenhouse. The Bluetooth beacon in the greenhouse continuously broadcasts signals and data ...
