Internet of Things（IOT, Internet of Things）It is generation information technology that sensor, internet and the information processing technology are highly merged, Internet of Things is widely used in industrialized agriculture, is mainly traced to the source in modern greenhouse environmental monitoring and regulation and control, product made important progress with the aspect such as pest diagnosis in recent years.And the modern greenhouse intelligent monitor system based on technology of Internet of things framework, it focuses on complete perception, stabilization transmission and 3 directions of intelligent use, and system is easy to extension, and application is strong, is the main development direction of modern greenhouse intelligent monitor system.
The content of the invention
The invention aims to construct, autgmentability is high, highly versatile greenhouse intelligent monitor system, devises a kind of greenhouse intelligent monitoring system based on Internet of Things.
The technical solution adopted for the present invention to solve the technical problems is：
Greenhouse intelligent monitoring system based on Internet of Things is mainly made up of on-site supervision subsystem, remote monitoring subsystem and the part of database subsystem 3, it is relatively independent in each subsystem design, rely on polymerism relatively low, be with good expansibility, operability and application.
Described on-site supervision subsystem is C/S frameworks, the monitoring software run on site monitoring computer is communicated by CANOpen agreements and the greenhouse data gathering based on Distributed C AN buses with control system, realizes collection and the control of equipment to the greenhouse main environment factor.Input module receives the greenhouse micro-climate factor of sensor collection（Air themperature, humidity, solar radiation etc.）With outdoor weather information（Air themperature, humidity, wind speed, wind direction, intensity of illumination etc.）, sending them in CAN, site monitoring computer is received these data and is shown in real time by CAN communication clamping, while storing in database.Output module receives the control signal from on-site supervision software by CAN, and the action of control relay, the corresponding actions of relay control environmental control of greenhouse equipment（Blower fan, skylight, wet curtain, sunshade net etc.）Start and stop.The sampling period of the Real-time Collection of greenhouse data is 1s, and in order to keep to-noise ratio higher, setting data grandfather cycle is 30s.Further need exist for being smoothed data.
Described remote monitoring subsystem is B/S frameworks, by data acquisition layer, logic application layer and performance alternation of bed are constituted, remote monitoring subsystem is built using the asynchronous data transaction mode based on Ajax technologies, entirety realizes the acquisition of greenhouse information, control command is assigned, and there is provided quick friendly user mutual logic, with user's registration management, real time environment information preview, the inquiry of historical data and derivation, equipment remote control, the functions such as video monitoring, the scientific research and administrative staff for alloing to be in strange land easily obtain greenhouse environment information, monitoring means are provided, strengthen its dynamic role and intervention capacity.
Described database is the bridge of their communications between remote monitoring subsystem and on-site supervision subsystem.On-site supervision subsystem carries out historical query with analysis by the storages such as treated real time environmental data, status information of equipment and equipment control daily record to database for user.The information that on the one hand remote monitoring subsystem will store in database shows long-distance user, and on the other hand by the control decision table of the control command write into Databasce of long-distance user, on-site supervision subsystem real time polling control decision table realizes the control to greenhouse facilities.
Described temperature system intelligent control method models the correlation theory with control using mixed-valued counter, and equipment state recognizes the image recognition technology using Zernike squares with calibration.
The beneficial effects of the invention are as follows：
Greenhouse intelligent monitoring system based on Internet of Things can not only realize automatic data collection, in real time display, visual data query and the analysis of greenhouse environment parameter, enable in particular to monitor the working condition of field apparatus, realize Based Intelligent Control, and combine the work characteristics of greenhouse facilities, greenhouse temperature system intelligent control algorithm based on mixed-valued counter model is applied in environment conditioning, the Based Intelligent Control of greenhouse facilities is realized.Image recognition technology based on Zernike squares is applied to the detection of equipment state, the automatic calibration of equipment is realized, Ajax technologies are made full use of, the real-time update of environmental data and equipment state and synchronous is realized.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is system the general frame.
Fig. 2 is system Ajax request process.
Fig. 3 is manual control flow.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As shown in figure 1, the greenhouse intelligent monitoring system based on Internet of Things is mainly made up of on-site supervision subsystem, remote monitoring subsystem and the part of database subsystem 3.On-site supervision subsystem is C/S frameworks, and the monitoring software run on site monitoring computer is communicated by CANOpen agreements and the greenhouse data gathering based on Distributed C AN buses with control system, realizes collection and the control of equipment to the greenhouse main environment factor.Remote monitoring subsystem is B/S frameworks, is made up of data acquisition layer, logic application layer and performance alternation of bed.Database is the bridge of their communications between remote monitoring subsystem and on-site supervision subsystem.
As shown in Figure 2, need to show current greenhouse data and status information of equipment in real time in remote monitoring subsystem, and it is related to the operations such as substantial amounts of the inquiry of historical data, statement analysis, parameter setting, equipment control, building remote monitoring subsystem using the asynchronous data transaction mode based on Ajax technologies herein can provide the user the data interaction experience of smoothness, and server burden can be reduced, improve network transmission efficiency.SetInterval functions are called in JavaScript timings in remote client browser, constantly trigger Ajax engines, data are sent to Web server update request, newest environmental data and front page layout is returned to JSON forms in server lookup database, so as to realize the real-time update of greenhouse data.
As shown in figure 3, the control model of devices in system is divided into and controls and automatically controls manually, can in two kinds of control models free switching.Control manually can also can both realize in Monitor And Control Subsystem on Web Terminal Server Clients at the scene, and intelligent control algorithm only operation in Monitor And Control Subsystem at the scene.Manual control process is as shown in figure 4, control instruction may be from Terminal Server Client is also possible to implement at the scene.When remote control is implemented, system is by remote control commands write into Databasce, on-site supervision software reads the control instruction of remote port, corresponding control subfunction is called to implement to control to equipment, and by the equipment state write into Databasce after renewal, Terminal Server Client reads the equipment state of passback, the page is updated, so as to complete the control to equipment.When field control is implemented, control instruction is directly assigned to on-site supervision software, calls corresponding control subfunction to realize the control to equipment, and equipment state equally returns to Terminal Server Client after changing.
