Router 3 connects ESP8266 terminal device 4 by WIFI signal；
ESP8266 terminal device 4 is separately connected relay 7, Temperature Humidity Sensor 9, optical sensor 10 and smog sensing
Device 11；
Relay 7 is separately connected air-conditioning 5, fan 6 and television set 8；
Wherein, it is installed in raspberry pie main control module 2 and runs Raspbian system, Raspbian is one, and to simplify be tree
The linux system of certain kind of berries group design.By building HomeAssistant server and MQTT server in Raspbian system,
It is set using the data acquisition of MQTT protocol realization Temperature Humidity Sensor 9, optical sensor 10 and smoke sensor device 11 and relay
Standby switch control.HomeAssistant is the domestic automation system based on Python.
When environment measuring control system works, raspberry pie main control module 2 and 4 node of ESP8266 terminal device pass through WIFI
It is connected to router 3 and realizes a local area network building.Temperature Humidity Sensor 9 (DHT11) is used for the indoor temperature and humidity of real-time monitoring,
Optical sensor 10 (GY-30) monitors intensity of illumination, and smoke sensor device 11 (MQ-2) monitors kitchen CH4, CO gas concentration.
DHT11 is connected with the D4 of ESP8266NodeMCU mouth in concrete scheme, the D1 of GY-30 and ESP8266NodeMCU,
D2 mouthfuls are connected, and MQ-2 is connected with the D9 of ESP8266NodeMCU.DHT11, GY 30, MQ-2 are by ESP8266NodeMCU
3.3V and GND power supply.ESP8266 module can be connected to router according to the program setting being burnt in chip after powering on, and will pass
The data of sensor acquisition are sent to ESP8266 by I/O port, and ESP8266 is sent to MQTT server by MQTT agreement.
Communication between ESP8266 and Home Assistant is as shown in Figure 2.
As shown in Fig. 2, ESP8266NodeMcu hardware module passes through the MQTT on MQTT protocol communication channel and raspberry pie
Server (MQTT-Broker) connection, Home Assistant server pass through MQTT protocol communication channel and MQTT server
Connection.
MQTT, that is, message queue telemetering transport protocol, is one of Machine To Machine (M2M) and Internet of Things connection protocol, it
It is designed to a very publication for lightweight and subscribing mode and carries out message transmission.In client and server communication process
In, client sends the data to MQTT-Broker first and will do it after MQTT-Broker receives the message of client publication
The filtering of message.There are mainly three types of modes for message screening: filtering, content-based filtering based on theme, the sieve based on type
Choosing.MQTT-Broker carries out that specific message can be sent to the client for having subscribed the message after message screening.In this way,
Circulation carries out the transmission for constantly completing data between client and MQTT-Broker.
As shown in figure 3, in the present system, ESP8266, Home Assistant are clients, MQTT-Broker is service
Device.ESP8266 can be arranged after opening according to the good program of burning, first carry out system initialization, the router specified in connection；So
ESP8266 issues the data that sensor acquires by MQTT agreement afterwards, and the data of publication are stored to MQTT-Broker,
MQTT-Broker can give received data forwarding the client for having subscribed particular message.Meanwhile ESP8266 can also be subscribed to
Specific message.Home Assistant connects specified home gateway automatically after opening, carry out system initialization；Then pass through
Monitoring event (detection MQTT-Broker whether give out information, whether the system page has interactive operation), when detecting MQTT-
Broker has issued message and HomeAssistant also has subscribed this message, and HomeAssistant can be MQTT-
Data transmitted by Broker are stored into its included database, and front end page calls the corresponding contents in database to be shown
Show, the content that user can then show according to front end at this time checks corresponding information or carries out control operation.When user is in page
When face controls relay switch.Such as: when opening relay, HomeAssistant can will open the news release of relay
It just will receive the instruction that relay is opened from MQTT-Broker to MQTT-Broker, the ESP8266 for having subscribed this message,
Open relay.
The utility model ESP8266 circuit design is as shown in Figure 4, Figure 5, and whole plate is powered by the USB interface of 3.3V, root
According to the characteristic of ESP8266 itself, corresponding pin function is set, and whole plate is not related to the use of analog interface, mainly with number
Interface come acquire sensor and relay feedback data.If Fig. 4, D1 and D2 are the coffrets of serial data, mainly for
It is designed in the characteristic of optical sensor；D3 is used for the reseting interface of core board；D4 is used to acquire DHT11 Temperature Humidity Sensor
Data are transferred on MQTT server by the data of feedback using the data processing in software program by MQTT agreement；D7
It is mainly used for controlling the relay of two low levels triggering with D8, since ESP8266 pin output voltage is smaller and relay
Device needs 5V voltage to trigger, so being amplified by signal of the triode to output to reach and be controlled relay
Effect.J3 and J4 is respectively two connecting terminals, is mainly used to connect controlled control equipment.
Those of ordinary skill in the art will understand that the embodiments described herein, which is to help reader, understands this reality
With novel implementation method, it should be understood that the protection scope of the utility model is not limited to such special statement and implementation
Example.Those skilled in the art can make according to the technical disclosures disclosed by the utility model various does not depart from this reality
With novel substantive various other specific variations and combinations, these variations and combinations are still in the protection scope of the utility model
It is interior.
