Abstract
The present invention is that one kind can be by the soil temperature sensor of 220V power line transmission signals.It is not required to rearrange signal wire using this sensor, under the premise of guaranteeing reliability, largely reduces engineering construction cost.
Description
Technical field
The present invention is that one kind can be by the soil temperature sensor of 220V power line transmission signals.Technical field is related to electricity
Line of force carrier communication and measuring instrument.
Background technique
Present invention is mainly used for the measurements in wisdom agricultural production to the soil moisture, it can also be used to other fields.
Wisdom Agricultural Monitoring is bound to be related to the transmission method of signal, this method be related to the system construction cost and
Reliability.At present using it is more be the wire transmission method of layout data line and the radio transmitting method of Zigbee mode.
The wireless transmission of Zigbee mode is a kind of wireless telecommunications similar to femto cell, the construction cost of this wireless communication mode
To be lower than the wire communication of data line.But stability, reliability are difficult to compare with wire communication, are especially disastrous days
Gas is often affected.
Electric line carrier communication is a traditional technology.It is applied in 35kV high pressure and 10kV medium voltage network compares into
It is ripe.Electronic equipment on 380V/220V low-voltage power line due to carrying is too many, and network noise is too big, is difficult to be used for signal
Transmission.Although technologies such as existing powerline remote meter readings, effect is all undesirable, so not being widely popularized.
Strong and weak electricity data converting function module of the invention has strong anti-interference ability.It is preferable for the first time in the world
It solves under high-noise environment, signal real-time Transmission and reception, stable signal transmission, nothing interferes with each other.The present invention, largely
Save data line arrangement.Under the premise of guaranteeing reliability, the construction of wisdom agricultural monitoring system is largely reduced
Cost.
Summary of the invention
A kind of soil temperature sensor based on power carrier communication, it is characterised in that: including soil temperature sensor
(1), carrier wave measurement port module (2), D.C. regulated power supply (3), the measuring signal output port of soil temperature sensor (1) with
The measuring signal input port of carrier wave measurement port module (2) connects, and D.C. regulated power supply (3) gives soil temperature sensor respectively
(1) it powers with carrier wave measurement port module (2).Soil temperature sensor (1) be the thermistor measured for the soil moisture or
Thermocouple etc..Carrier wave measurement port module (2) includes analog/digital signal conversion functional module (2-1), address code functional module
(2-2), strong and weak electricity data converting function module (2-3), with signal input port, light current input port and 220V forceful electric power end
Mouthful, digital signal can pass in and out carrier wave measurement end mouth mold from 220V forceful electric power port by strong and weak electricity data converting function module (2-3)
Block (2).D.C. regulated power supply is that 220V can be flowed the device that alternating current is converted into low-voltage DC, is given soil temperature sensor (1)
Electric power is provided with carrier wave measurement port module (2).
The analog signal of soil temperature sensor (1) measurement, passes through the analog/digital in carrier wave detection port module (2)
Function switching signal module (2-1) is converted to digital signal first, then adds address code by address code functional module (2-2), most
It is reached on power line by strong and weak electricity data converting function module (2-3) afterwards.At strong and weak electricity data converting function module (2-3)
The signal managed, can reach the controller of wisdom agricultural control system by 220V power line, and controller can be known according to address code
Not Chu measuring signal from where issue.
The present invention is application of the power carrier communication in measuring instrument, which can also be used for 380V three-phase
Under communication environment.
Detailed description of the invention
Fig. 1 is structure chart of the invention.
Specific embodiment
Soil temperature sensor is made with thermistor.D.C. regulated power supply uses AC/DC Switching Power Supply, and it is straight to provide 12V
Galvanic electricity.Analog/digital signal conversion functional module, address code functional module, strong and weak electricity data converting function module are made respectively
IC chip.Structure chart according to the invention is assembled into the soil temperature sensor based on power carrier communication.
