Description

A kind of method of humiture being monitored based on the wireless senser networking

Technical field

The present invention relates to wireless monitoring method, relate in particular to the method for humiture being monitored based on the wireless senser networking.

Background technology

In people's daily productive life, in the time of will realizing the temperature acquisition of multiple spot such as a large granary or green house of vegetables, need to connect a lot of and complicated transmission line to main frame from each sensor node according to the wire transmission scheme, green house of vegetables need to keep certain humiture, get off for a long time and can cause corrosion to transmission line, damage, thereby affect the normal operation of whole system, the in addition data volume transmitted of multi-point Temperature Acquisition System and little, and the requirement to message transmission rate is not high yet, and the collection transmission of therefore adopting wireless mode to carry out signal is very good.

Summary of the invention

The invention provides a kind of method of humiture being monitored based on the wireless senser networking, the method may further comprise the steps:

The sensor data acquisition step is obtained the humiture data with the SHT10 chip;

Data realize the radio communication of sensor at the transmitting step of zigbee network with radio frequency unit CC2430 chip;

The Data Integration step of aggregation node;

The server data treatment step uses MSP430 as processor, realizes the processing to data;

Air-conditioning control step based on the infrared modulation demodulation principle;

The inventive method utilizes Radio Transmission Technology to realize data transfer, realizes simultaneously accurately the processing in real time of humiture collection data of warehouse, the factory building of various scales by node for data forwarding; Can realize accurately humiture is maintained in advance setting value by the infrared control system simultaneously.

Fig. 2 is SHT10 chip internal structure figure.

Fig. 3 is the wireless communication module synoptic diagram.

Embodiment

SHT10 chip internal structure figure as shown in Figure 2, the flow chart of steps of the inventive method as shown in Figure 1, at first utilize two sensors to produce respectively relative humidity, temperature signal when gathering humiture information, then through amplifying, deliver to respectively A the D converter carry out mould/number conversion, calibration and error correction, left backly by the two-wire serial interface data of relative humidity and temperature are delivered to μ C, utilize μ C that reading value is carried out nonlinear compensation, when environment temperature TA ≠+25 ℃, need to carry out temperature compensation to relative humidity sensor.

After the SHT10 chip obtains the humiture data, use radio frequency unit CC2430 chip to realize the radio communication of sensor, the wireless communication module synoptic diagram as shown in Figure 3.

By the stage of converging it is integrated after the data transmission.

Be sent to processor MSP430 behind the Data Integration, realize the processing to data.

By the control of infrared adjustment demodulator circuit realization to air-conditioning equipment, thereby reach stable humiture environment.
