Singular perturbation theory-based agaricus bisporus cultivation greenhouse remote monitoring system

Abstract

The invention discloses a singular perturbation theory-based agaricus bisporus cultivation greenhouse remote monitoring system. The system comprises a greenhouse, a detection sensor group, an environment adjustment device, an LQR controller, a GPRS module, a monitoring gateway, a data forwarding repeater, a data platform, a high-definition camera and a mobile terminal; the detection sensor group acquires environmental parameters and transmits the environmental parameters to the LQR controller through the data forwarding repeater; the high-definition camera is connected with the data platform through a TD-LTE network; the LQR controller is connected with the monitoring gateway through the GPRS module and controls the environment adjustment device; the monitoring gateway is connected with the data platform; and the mobile terminal is connected with the data platform through the TD-LTE network. According to the agaricus bisporus cultivation greenhouse remote monitoring system of the invention, a wireless data acquisition and remote control mode is adopted, so that the problems of complex greenhouse wiring and poor control stability can be solved. The system of the invention has the advantages of convenient control, high reliability, high precision and the like.

Description

technical field [0001] The invention relates to the field of Agaricus bisporus cultivation, in particular to a remote monitoring system of a Agaricus bisporus cultivation greenhouse based on the singular perturbation theory. Background technique [0002] Existing studies on remote monitoring of edible mushroom greenhouse environments rarely involve Agaricus bisporus cultivation. The existing greenhouse remote control system mainly has two methods: ①Transmit the greenhouse environmental parameters collected by the detection sensor group to the remote data platform through the network, provide parameter query and alarm functions, and do not provide real-time control functions; and the transmission of video signals is due to The high requirements of the network lead to poor versatility of mobile terminal services. ②Use single-chip microcomputers, PLCs and other controllers to send greenhouse environmental parameters to mobile terminals through wireless modules, and mobile termi...

Problems solved by technology

[0006] The purpose of the present invention is to provide a remote monitoring system for the Agaricus bisporus cultivation greenhouse based on the singular perturbation theory, which solves the problems encountered in the environmental monitoring of the traditional Agaricus bisporus cultivation greenhouse: complex wiring in the greenhouse; high investment and maintenance costs; greenhouse control Poor accuracy; poor versatility of remote services; poor intuition and interactivity of the monitoring system; real-time environmental conditions of the growth of Agaricus bisporus cannot be tracked in real time. Through the application of the singular perturbation theory, the LQR controller is adopted according to the control requirements of the growth environment of Agaricus bisporus , through the LQR controller, the environment of the Agaricus bisporus greenhouse is automatically adjusted at different stages to improve the accuracy of the greenhouse environment control; the environment of the Agaricus bisporus greenhouse is remotely monitored through the mobile terminal, making the cultivation of the Agaricus bisporus greenhouse more intelligent
