Brief description
Fig. 1 is the layout structure figure of the Event tourism system of the present invention.
Specific embodiment
In order that the technical problem to be solved, technical scheme and beneficial effect become more apparent, below tie
Close drawings and Examples, the present invention will be described in detail.It should be noted that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention, the product enabling said function belongs to equivalent and improvement, all comprises
Within protection scope of the present invention.Concrete grammar is as follows：
Embodiment 1：
The Event tourism system of the present invention is based on Internet of Things, and Internet of Things is divided into three-tier architecture, is sensing layer, network
Layer, application layer.Sensing layer is located at the bottom of Internet of Things framework, for realizing the acquisition of data message.Internet is located at centre
Layer, for being gone out information real-time Transmission by network means.Application layer is located at top layer, for realizing exchange, the information of resource
Transmission, the decision-making of scheme etc..
(1) sensing layer
Sensing layer, for perceiving and identifying the information in the external world, the extraneous event data of collection.Sensing layer is divided into master
Dynamic collection and passive collection two ways, for the information monitoring in local environment.In the present invention, sensing layer includes intelligent lamp
Tool switch, Intelligent electric socket, coulometric detector, sensor assembly.
(2) Internet
Internet is the passage of information transfer, realizes being connected with each other between modules, increased the letter between thing and thing
Breath interactive function.It can carry out physical propagation accurate, safe for the information perceiving.As fulcrum, Internet is various
The fusion of communication network, various communication networks include cable network, 3G network, WiFi network, mobile communications network, CHINA RFTCOM Co Ltd
Deng.
3) application layer
Application layer is the platform that Internet of Things realizes concrete application, is user oriented bridge, is the former of promotion technological innovation
Initiating power.Application layer mainly utilizes various terminal equipment, realizes the process of data and ingeniously should complete information technology and professional technique
Thorough fusion.Realize this target, application layer will solve sharedization of information and the safety problem of information.Internet of Things is being answered
Used time, first determine whether the attribute of object, if static attribute, the data information memory that directly object comprised, if
Dynamic attribute, then need to carry out infomation detection with sensor；Secondly, read the attribute of object, and information is carried out data and turn
Change；Finally, realize with information in must communication.
Wherein, the design of sensor, humiture, brightness are the important indicators of comfort level, and the enforcement of control strategy needs it
Data is provided to support.Traditional humiture, brightness measurement, by way of the monitoring of air-conditioning, have very big defect.Design is independent
Sensor can effectively indoor temperature, humidity be detected.
Selected humiture module needs satisfaction -20 to spend to 50 degree of temperature measurement range, (temperature measurement range of TC, 0
To 99% moisture measurement scope, and need less volume.Shadow measurement result being caused in order to avoid the temperature of circuit board
Ring, need between module and circuit board to increase gap to reduce conduction of heat.Therefore, Temperature Humidity Sensor selects SHT11 module, this mould
Block realizes temperature, moisture measurement simultaneously, is internally integrated measurement, calibration circuit it is ensured that the accuracy of data.
SHT11 module passes through serial line interface transmission data, but this serial port all improves in digital independent, energy consumption,
Incompatible with traditional change interface.The residence comfort of strong and weak impact people of the design illumination of sensor and eyestrain journey
Degree, while people are comfortable and energy saving.Show according to the study, indoor optimum illumination is 100lux, illumination is too high or mistake
Low human eye all can be damaged.
In electric power detection module, room can be realized using intelligent electric meter as the important component part in electricity system
The measurement of interior electricity, electric current, voltage, power etc., and by LCD liquid crystal display out.Traditional ammeter adopts mutual inductance mostly
Device realizing the measurement of voltage, electric current, power, has the shortcomings that certainty of measurement is low, volume is big.Intelligent electric meter adopts Novel electric quantity
Computation chip realizes the measurement of data, and this chip passes through SPI interface and main-machine communication.

During more than 5V, chip is started working.Using compensating network, improve the switching frequency of circuit, make the switching frequency of this circuit up to
500KHZ.And filter capacitor is set, reduce ripple interference, increase the work efficiency that Schottky diode improves circuit.
Intelligent gateway selects STM32F207ZET chip as MCU, and this chip is a low-power consumption, high performance process
Device, has abundant interface resource.The function of this integrated chip mainly has：Comprise abundant Ethernet resource, exclusive MAC controls
Device, supports multiple interfaces, has multiple pattern intervalometers, comprise senior, general, basic three kinds, carry multiple reset modes,
Hold USB full speed interface, have the RAM resource of 512K, see a mouthful Canis familiaris L. lamp for two.In Network Interface Module, intelligent gateway completes ether
Network data and the conversion of serial data, need mac controller and physics transceiver jointly to realize.
, as the control of indoor headend equipment, the selection of indoor controller is most important for indoor controller.One good room
Between controller not only can improve whole system performance, and the later maintenance cost of system can be reduced.Indoor controller is as room
In interior terminal unit, realize including the functions such as data acquisition, data display, data upload, Based Intelligent Control, user management.
User checks the information of indoor controller, carries out user first and logs in, and user profile input correctly can get in controller
Main interface.The main interface display house interior air quality of indoor controller, temperature, humidity, illumination etc.；Energy consumption monitoring interface
Power consumption information in display room, such as electric current, voltage, power, electricity etc.；Node state interface is used for showing light fixture, electrical equipment etc.
On off state, and manually controllable its switch；Contextual model interface is used for arranging operative scenario such as conference scenario, office scene
Deng；Timing controlled interface is used for manual setting electrical equipment, the working time of light fixture；System setting interface is used for manual modification module and believes
Breath, such as adds or deletion of node module.
It is wirelessly transferred middle use ICP/IP protocol, facilitate user to directly invoke.In the standby state, power consumption, less than 1mW, solves
The big problem of conventional radio transmission module dissipation of having determined.Not only there is abundant interface resource, have up to 16 pin mouths, interior
Put manostat, PLL assembly, built-in power amplifying unit, temperature collecting cell, temperature-compensating can be carried out, there are multiple work
Pattern, such as activation, sleep isotype are it is ensured that the low-power consumption of circuit.
