Abstract
The invention discloses a power line carrier communication based temperature and humidity acquisition system which comprises a temperature and humidity sensor for acquiring in-situ temperature and humidity. The temperature and humidity sensor is connected into a power grid through a power line carrier modulator used for modulating digital signals to electric signals capable of being transmitted on a power line, and a power line demodulator which is used for demodulating the electric signals transmitted in the power line to the digital signals is connected with the power grid and also connected with a monitoring center. Data information transfer between the temperature and humidity sensor and the monitoring center can be completed only with the power line through the 220V power grid, and the system is simple in structure, low in cost, convenient to install, and convenient for operation and maintenance management.
Description
Technical field
The present invention relates to industrial control field, be specifically related to a kind of humiture acquisition system based on power line carrier communication.
Background technology
All kinds of civilian, Industry Control is on-the-spot, the situation of ambient temperature and humidity is important parameter, therefore, to ambient temperature and humidity accurately, in time monitoring, significant.
Power line carrier communication is to take the communication of power system of the transmission medium that transmission line of electricity is carrier signal.Because transmission line of electricity possesses very firmly supporting construction, and set up 3 above conductors (generally having three-phase good conductor and one or two aerial earth wire), so when power transmission line is carried power current, the transmission carrier signal of using, not only economy but also very reliable.This comprehensive utilization becomes the preferential peculiar means of communication adopting of all power departments in the world already.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical matters to be solved is for providing a kind of humiture acquisition system based on based on power line carrier communication.
To achieve these goals, the present invention adopts following technical scheme:
A kind of humiture acquisition system based on power line carrier communication, the Temperature Humidity Sensor that comprises collection site temperature and humidity, described Temperature Humidity Sensor by one for the power line carrier modulator access electric power network that is the electric signal that can transmit on line of electric force by digital signal modulated, one is connected the connection of ，Bing Yu Surveillance center for the electric signal transmitting at line of electric force being demodulated into the line of electric force detuner of digital signal with described electric power network.
Further, the model of described Temperature Humidity Sensor is SHT11.
Further, described power line carrier modulator is arranged on Temperature Humidity Sensor inside.
Further, described power line carrier detuner is arranged on Surveillance center inside.
Further, described Surveillance center is provided with alarm device.
The invention has the beneficial effects as follows: between Temperature Humidity Sensor and Surveillance center, only need to utilize line of electric force, by 220V electrical network, just can complete data information transfer, system architecture is simple, with low cost, be convenient to install convenient operation and maintenance management.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is elaborated:
Fig. 1 is the circuit structure block diagram of humiture acquisition system of the present invention.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of humiture acquisition system based on power line carrier communication, the Temperature Humidity Sensor that comprises collection site temperature and humidity, Temperature Humidity Sensor by one for the power line carrier modulator access electric power network that is the electric signal that can transmit on line of electric force by digital signal modulated, one is connected the connection of ，Bing Yu Surveillance center for the electric signal transmitting at line of electric force being demodulated into the line of electric force detuner of digital signal with electric power network.
The model of described Temperature Humidity Sensor is SHT11.Described power line carrier modulator can be arranged on Temperature Humidity Sensor inside, forms a product.Described power line carrier detuner can be arranged on Surveillance center inside.Described Surveillance center is provided with alarm device.
In use, Temperature Humidity Sensor Real-Time Monitoring environment temperature and humidity, and Real-Time Monitoring value is transferred to the power line carrier modulator being attached thereto, by electric power network, transmit again, power line carrier detuner is processed the data that transmit, then be transferred to Surveillance center, the watch-dog of Surveillance center is by the temperature and humidity that shows that Temperature Humidity Sensor samples.
The alarm device that meets or exceeds preset value Shi， Surveillance center when humiture will send sound and light alarm, to point out user, user can be taken appropriate measures in time.
Above-described embodiment is just to allow one of ordinary skilled in the art can understand content of the present invention and implement according to this for technical conceive of the present invention and feature being described, its objective is, can not limit the scope of the invention with this.Every equivalent variation or modification that according to the present invention, the essence of content has been done, all should be encompassed in protection scope of the present invention.
