Market condition.By the on/off for the high/low Automatic level control relay contact that main control chip output terminal exports, it is outer to be achieved in control
The ON/OFF of circuit closer equipment.Fly-wheel diode can make relay be attracted after energy in coil pass through fly-wheel diode shape
Into circuit be released, reduce its interference to main control chip, the stability of strengthening system.
WiFi has Three models：STATION, AP, STATION+AP correspond to client, server-side (WiFi heat respectively
Point), connection upper level Wi-Fi hotspot and establish the WIFI hot spot of this level-one.Entire circuit can so be caused to adapt to different families
Situation is occupied, the circuit after networking can be connected into home router, and user is received as a whole set of circuit by the module for being connected into router
The entrance of instruction.It, can be using one of module in circuit as primary module by router in the environment for having router
LAN connected with circuit, user is connected into router LAN by mobile phone, and the control to circuit is can be achieved with by APP
System.In the environment of no router, then the hotspot name of one WiFi module of manual modification is needed, i.e., a self-defined reception refers to
The module of order, the module are also the starting point of networking, and next stage or the module with level-one pass through STATION patterns or AP+
STATION patterns being linked on primary module layer by layer.
Further, emitter of the cathode of each fly-wheel diode respectively with a NPN triode is correspondingly connected with,
The collector of NPN triode connects power supply, the output terminal of the base stage connection main control chip.It can be promoted by NPN triode
The driving force of main control chip.
Further, the data terminal of main control chip is connected with Temperature Humidity Sensor, the power end of Temperature Humidity Sensor and institute
The power interface connection of 5V is stated, to obtain temperature/humidity information of environment.
Further, regulated power supply is connected between the power interface and main control chip, regulated power supply is as electricity
Switching Core element is pressed, 5V voltage output 3.3V voltages is inputted, operating voltage is provided for main control chip.
The distributed internet-of-things terminal control circuit of the present invention, can be directly connected to various electrical equipments by interface, letter
Single convenient realize controls various household electric appliances equipment, and can each household electric appliances equipment be formed LAN and carried out
It is uniformly controlled.
Specific embodiment with reference to embodiments is described in further detail the above of the present invention again.
But the scope that this should not be interpreted as to the above-mentioned theme of the present invention is only limitted to following example.Think not departing from the above-mentioned technology of the present invention
In the case of thinking, the various replacements or change made according to ordinary skill knowledge and customary means should all be included in this hair
In bright scope.
Description of the drawings
Fig. 1 is the circuit diagram of the distributed internet-of-things terminal control circuit of the present invention.
Specific embodiment
The distributed internet-of-things terminal control circuit of the present invention as shown in Figure 1 has the master control core connected by I/O interfaces
Piece U4 and AccessPort module J 1.Main control chip U4 uses the control module of ESP8266WIFI models.The output of main control chip U4
End connects 3 control external equipments and opens/the switch unit of pipe respectively, and being respectively equipped with control terminal in each switch unit passes through IN4007
The sustained diode 1, D2 of type, D3 is connected with the output terminal of main control chip U4, output terminal is correspondingly connected with switch interface J2, J3, J4
Relay U1, U2, U3.Each sustained diode 1, D2, the cathode of D3 respectively with a NPN triode Q1, the transmitting of Q2, Q3
Pole is correspondingly connected with, NPN triode Q1, Q2, and the collector of Q3 connects power supply VCC, the output of the base stage connection main control chip U4
End.The power interface J5 that the power port of main control chip U4 passes through regulated power supply U5 connections 5V.The data terminal of main control chip U4 connects
The Temperature Humidity Sensor J6 of DHT11 models is connected to, the power end of Temperature Humidity Sensor J6 is connected with the power interface J5 of the 5V.
The control circuit of Fig. 1 single household electric appliances in order to control, the wifi that multiple control circuits can be passed through 2.4GHz
Network mutually establishes connection, and by the LAN of one information interchange mode for being similar to crotch of udp broadcast connection setup, often
