Brief description of the drawings
Fig. 1 is the overall theory diagram of control system of the present invention；
Fig. 2 is signal conditioning circuit theory diagram of the invention.
Embodiment
Technical scheme is described in further detail with reference to specific embodiment.
A kind of irrigation automation control system as shown in Figure 1, including PLC, Temperature Humidity Sensor, signal condition
Circuit, automatic valve, inlet channel road, outlet conduit road, wireless transceiver and display, the Temperature Humidity Sensor is through signal
Modulate circuit and the signal acquisition input of PLC are connected, the control signal output connection automatic valve of PLC controllers
The control circuit of door, automatic valve is located between inlet channel and outlet conduit, and wireless transceiver gathers the number of PLC controllers
According to transferring data to display by being wirelessly transferred and shown, the inlet channel stretches into water storage away from automatic valve one end
In pond, outlet conduit is shone away from automatic valve one end connection flower, and the flower shines to be shone for automatic rotary flower, the PLC controllers
It is also associated with hand/automatic change-over.
Signal conditioning circuit theory diagram as shown in Figure 2.Including sensor, pre-amplifying module, current monitoring module,
Current rectifying and wave filtering circuit, power supply, A/D modular converters, voltage detection module, master controller, reminding module and memory module, it is special
Levy and be：Sensor is connected with pre-amplifying module, current detection module, A/D modular converters, reminding module；Sensor is also
It is connected with current rectifying and wave filtering circuit and power supply；Power supply is connected with master controller, master controller and voltage detection module and memory module
It is connected.The master controller is single-chip microcomputer.
The basic procedure of sensor signal conditioning is：The physical quantity signal of sensor is converted into electric signal, by amplifying,
After filtering, AD converters are sent into, data signal is converted to and is handled.Fig. 1 gives the exemplary flow of signal conditioning circuit
Cheng Tu, including preposition amplification, two grades of amplifications, Signal Pretreatment（Filtering, rectification, amplitude adjusted etc.）, signal recently enters AD
Converter, can all introduce noise in the links of signal condition.Current AD converter input voltage scopes are 03V
Or 0~5V is, it is necessary to sensor signal be amplified to make full use of AD input range, and filter to weaken noise.
For some sensors, such as thermopile sensor device, output voltage signal, scope is micro- to hundreds of in more than ten microvolts
Volt.So the operational amplifier for doing preposition amplification is particularly significant, suitable parameter is selected, to reduce making an uproar for amplifier itself introducing
Sound.Three main noise sources are：Voltage noise, the current noise of amplifier, the thermal noise (Johnsonnoise) of resistance.One
As the noise profile feature of amplifier be：White noise is presented in intermediate frequency, low frequency is the 1/f noise (square root of spectral density and frequency
It is inversely proportional), 1/f noises are the Main Noise Sources of dc-couple measurement.Amplifier with Auto zeroing (auto-zero) feature
1/f noises can be weakened significantly, while having minimum input offset voltage (several uV), low frequency is best suited for or straight
Flow the measurement of small-signal.
