Summary of the invention
The utility model purpose be to provide a kind of can to domestic environment detect in real time and complexity is low, cost is low, low in energy consumption, postpone short, the large and safe Smart Home EMS of network capacity, specifically realized by following technical scheme.
A kind of Smart Home EMS, this system comprises environmental detection sensor group, control module and the data exchange module that connects successively.
Described Smart Home EMS, further design is that described environmental detection sensor group comprises temperature sensor DS18B20, humidity sensor DHT11, air mass sensor MP135.
Described Smart Home EMS, further design is, described data exchange module comprises display circuit, serial communication circuit, the infrared remote controller that is connected with an external display, and this system also comprises the mini-fan and the motor-drive circuit that is connected with described direct current machine that drives with a direct current machine.
Described Smart Home EMS, further design is, described control module comprises three CC2430 chips, these three CC2430 chips are followed successively by data collection station chip, central controller and instruction outlet terminal chip, be connected with the input port of central controller after described data collection station chip is connected with described environmental detection sensor group, described central controller is connected with serial communication circuit with display circuit and is connected with infrared remote controller and motor-drive circuit by instruction outlet terminal chip.
The beneficial effects of the utility model are:
The utility model can detect in real time to domestic environment, and complexity is low, cost is low, low in energy consumption, postpone short, network capacity is large and safe; This system's scope of application is extensive, can detect various indoor environments, provides the data reference for improving indoor environment.

Embodiment
Below in conjunction with Figure of description and specific embodiment the utility model is further specified.
This Smart Home EMS comprises environmental detection sensor group, control module and the data exchange module that connects successively.The environmental detection sensor group comprises temperature sensor DS18B20, humidity sensor DHT11, air mass sensor MP135.Data exchange module comprises display circuit, serial communication circuit, the infrared remote controller that is connected with an external display, and this system also comprises the mini-fan and the motor-drive circuit that is connected with direct current machine that drives with a direct current machine.Control module comprises three CC2430 chips, these three CC2430 chips are followed successively by data collection station chip, central controller and instruction outlet terminal chip, be connected with the input port of central controller after the data collection station chip is connected with the environmental detection sensor group, central controller is connected with serial communication circuit with display circuit and is connected with infrared remote controller and motor-drive circuit by instruction outlet terminal chip.
Control module is made of the CC2430 minimum system.When the data acquisition button of central controller is pressed, central controller sends the order of data acquisition to terminal, terminal receives order and enters normal mode of operation from sleep pattern, and the collection of environmental data is periodically carried out in beginning, after each collection is finished, send the data to central controller, central controller carries out the arrangement of data and it is shown in LCD display.And make load on the load node according to these data.And control is according to arranging by the software of PC end.So just realized full-automatic home environment, all can transfer to system for most of household electrical appliances and automatically control.
Its workflow is as follows: central controller is set up ZigBee-network after the start, and the node search for networks also adds, after the networking success, and LED3 flicker on the terminal, LED3 lamp Chang Liang on the central controller.Send data-collection command, the node that many environmental sensors are housed begins every 10 minutes collection one secondary data, and after successfully collecting, send to central controller, self close all resources, enter standby mode, until inner timer wakes it up, after central controller receives data, because the air mass sensor value is subjected to temperature, humidity effect calculates compensation to it first, then it is presented on the LCD, if ambient temperature is opened motor greater than the design temperature notice with the node of respective load, human body surface is lowered the temperature, if indoor temperature is down to design temperature when following, send the motor stalling order.Network is laggard to enter sleep pattern to all terminals successfully adding, until receive the order that central controller sends.And infrared module can be used as the purpose that reaches remote controlled electrical household appliances by the coding of study domestic electrical equipment remote controller.
Sensor assembly comprises temperature, humidity, air mass sensor, and temperature, humidity, the air quality of environment detected.The data wire of temperature, humidity, air mass sensor meets respectively P1_6, P1_7, the P0_0 of CC2430.Adopt direct current machine as the control motor, the P1_1 of CC2430 has the driving force of 20mA, can drive motor.But since motor stop can be very large to the at that moment moment that begins to rotate, so need between chip 1,2 pins, add a large electric capacity, perhaps adopt ULN2003 to carry out electric current and amplify.
The display circuit Main Function is to show the information such as Current Temperatures, humidity, air quality.Serial communication mainly is to communicate by letter the RS-232 communication protocol of employing for system and computer.And infrared module can be used as the purpose that reaches remote controlled electrical household appliances by the coding of study domestic electrical equipment remote controller.
