Preferably, the cloud platform is an exempt internet of things platform ONENET.
Preferably, the human-computer interaction module comprises a display screen and an LED lamp.
The invention has the beneficial effects that:
1. the invention provides a modernized management mode of a cluster greenhouse, and one intelligent gateway can control at most 255 greenhouses in a certain range. The system is set to be a gateway single-point access internet, each acquisition control circuit is connected with the gateway, data are concentrated to the gateway and are transmitted through the gateway and the cloud platform, and the problem that the cluster greenhouse is not easy to completely cover due to the fact that the network is far away in the area is solved.
2. The intelligent gateway acquires the environmental information of each acquisition control device in a polling mode, and adopts an EDP (electronic data processing) protocol to send the environmental information to the cloud platform, so that the problem that the intelligent gateway articulates a plurality of acquisition control devices to transmit data on the same 485 bus is solved. And the user can check the line graph of the environment information through the cloud platform and perform corresponding control operation on each device.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-2, a distributed intelligent gateway for greenhouses, comprising a central processing unit, wherein the central processing unit is electrically connected with a power supply module, the power supply module is electrically connected with a 485 communication module, the 485 communication module is connected with the central processing unit through a signal line, the 485 communication module is connected with an acquisition control module through a signal line, the power supply module is electrically connected with a human-computer interaction module, the human-computer interaction module is electrically connected with the central processing unit, the power supply module is electrically connected with a Wifi module, the Wifi module is electrically connected with the central processing unit, the Wifi module is connected with a cloud platform through a wireless network, the Wifi communication module mainly completes data interaction between the gateway and the cloud platform, the 485 communication module mainly completes data transmission between the gateway and the acquisition control device, the cloud platform is a free internet of things platform oneet, the platform supports various general protocols and provides an open application, and integrated instrument is abundant, safe and reliable facilitates the use, provides webpage and cell-phone APP function, and the human-computer interaction module includes display screen and LED lamp, can show the condition that current intelligent gateway received and sent data, and intelligent gateway passes through wifi and connects the cloud platform, adopts the EDP agreement to carry out data transmission between the two. The wifi part is provided with a disconnected network reconnection function, if the wifi part detects that the wifi network is not connected, the intelligent gateway enters a waiting state, network connection requests are initiated every 1 minute, the intelligent gateway returns to normal work after the wifi network is connected, the trouble of restarting the system after the network is disconnected is avoided, the intelligent gateway can be connected with a plurality of acquisition control devices through a 485 bus, the intelligent gateway only needs to work in the wifi environment due to the fact that the intelligent gateway adopts a single-point network access mode, the acquisition control devices can work in a network-free environment, data sent by the acquisition control devices connected with the intelligent gateway need to be consistent with the data format of data received by the gateway, the data format of the environment information received by the intelligent gateway is a start symbol, an address bit, environment information, a temperature lower limit, a temperature upper limit and an end symbol, the intelligent gateway acquires the environment data from each acquisition control module in a polling mode and uploads the environment data to a cloud platform, the data format is: the start character + the address + the end character avoids data collision in the 485 bus caused by simultaneously sending data by a plurality of devices. When polling is carried out, if corresponding information is not received within 15s, the acquisition control equipment is skipped to carry out polling continuously downwards, the influence on the whole system caused by accidental conditions such as damage of individual equipment is avoided, an OLED display screen in an intelligent gateway mainly displays the address of transmitted polling data and the data of environmental information received by a gateway part, when the gateway transmits the polling data, the current polling address is displayed on the OLED screen, and when the intelligent gateway receives the environmental data, the gateway firstly analyzes the environmental data and then displays the environmental data on the OLED screen.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
