Specific embodiment
The utility model is described in further detail below with reference to embodiment and referring to attached drawing.
Embodiment 1:
One embodiment of the utility model is a kind of sensor device for being suitable for shallow water water level detecting.It is so-called shallow
Water generally refers to the occasion that water level is not higher than 50cm, as reservoirs and tanks water level detecting in building water supply system and road product flood are deep
Degree detection etc..
Sensor structure is as shown in Figure 1, external is sensor outer housing 1.Sensor outer housing 1 is made of ABS plastic material.
There are two sensor fixing threaded holes 3 for 1 lower section of sensor outer housing, divide left and right settings, can will be passed by the sensor fixing threaded hole
Sensor is firmly fixed.Sensor internal is provided with U-shaped measuring flume 5, is equipped with deflector hole 4, measuring flume in the lower section of measuring flume 5
5 pass through deflector hole 4 and external environmental communication to be measured.
Sensor realizes water level detecting, respectively left measuring rod 2 and right measuring rod 3 using two measuring rods.Such as Fig. 2 institute
Show, left measuring rod 2 is inserted in the left side of measuring flume 5, is made of the copper bar of diameter 5mm, draws wiring and ground terminal from the measuring rod
Connection.Left measuring rod 2 is able to maintain the structural focus balance and stability effect of measuring device, in addition some measurement occasions can be
Scale is directly identified on left measuring rod 2, direct eye-observation needs that the corresponding area of observation coverage is arranged at this time on shell.
Right measuring rod 6 is inserted in the right side of measuring flume 5, and using diameter 5mm ambroin bar as supporter, surface applies poly- silicon
For the super-hydrophobic dosage form of oxygen alkane at hydrophobic interfaces, which can prevent water after repeatedly measuring from remaining in influence survey in resistance wire
Then accuracy of measurement uses area of section 1mm2Nichrome resistance wire is wound on bar.
The electrical schematic diagram of sensor is as shown in Figure 3.Wiring is drawn from the upper end of right measuring rod 6, as water-level simulation amount
Output point S1, S1 are connected by current-limiting resistance R1 with positive pole.In addition, distinguishing at the different height of right 6 shaft of measuring rod
Wiring is drawn, as water level switch amount output point S2, S3, S4, water level switch amount output point S2, S3, S4 pass through pull-up electricity respectively
Resistance R3, R4, R5 are connected with positive pole.The lower section of right measuring rod 6 then passes through wiring and connect with ground terminal.In the present embodiment, power supply
For+5V, 51 Europe of resistance value of R1, it is also 51 Europe that R2, which is the resistance wire resistance value of right measuring rod 6, and the resistance value of R3, R4, R5 are 10k.
The water-level simulation measurement principle of sensor is as follows: in tested water body is from deflector hole 4 into measuring flume 5, S1 point
Output voltage values V can be calculate by the following formula:
V=5* (R2 '+R2 " //R)/(R1+R2 '+R2 " //R)
In above formula, R1 is current-limiting resistance value, and R2 ' is resistance value of right 6 resistance wire of measuring rod in water surface above section, R2 "
For the resistance value of right 6 resistance wire of measuring rod part below the water surface, R is the resistance value of water, and R2 " //R indicates that R2 " is in parallel with R
Resistance value.
Due to the resistance value R very little of water, and it is much smaller compared to R2 ", therefore S1 point output voltage values calculation formula can be into one
Step simplifies are as follows:
V=5* (R2 ')/(R1+R2 ')
Therefore, right 6 resistance wire of measuring rod can be found out in the resistance R2 ' of water surface above section, then root by measuring V value
Water depth can be found out by accounting for entire R2 ratio according to R2 ', specific formula is as follows:
H=H* (R2 '/R2)
In above formula, h is water depth, and H is the height of right measuring rod 6.
The water level switch measurement principle of sensor is as follows: before water flooding S2, S3, S4 output switch parameter point, this
A little point output high level, after flooding, these point output low levels, therefore by the detection to S2, S3, S4 switching value can be with
Understand water level and is presently in section.
The concrete application mode of the present embodiment is as follows: being first fixed on sensor by sensor fixing threaded hole 3 tested
Water bottom opens deflector hole 4, connects the extraction of left measuring rod 2 and is wired to ground terminal, connect right measuring rod 6 draw wiring respectively with
Positive pole, ground terminal and corresponding water-level simulation amount and switch acquisition point pass through acquisition equivalent water level analog quantity and water level
Switching value is converted into respective water depth.
Although the utility model has been described by way of example and in terms of the preferred embodiments, embodiment is not for limiting the utility model
's.In the spirit and scope for not departing from the utility model, it is practical new to also belong to this for any equivalent change or retouch done
The protection scope of type.Therefore the protection scope of the utility model should be mark with the content that claims hereof is defined
It is quasi-.
