, the component mentioned in this section due to not being the utility model main points of the application, is not drawn into the accompanying drawings.
The operation principle of this wall-mounted humiture transducer：
Installation wall temperature-compensation method based on above-mentioned wall-mounted humiture transducer：If aid in temperature and humidity measurement point
It is T that temperature is measured at WS11, since auxiliary temperature and humidity measurement point WS1 designs are in the edge of transmitter wiring hole 3, T1Closely
Approximately equal to wall temperature, so T1Represent the temperature of installation wall.It is T that if temperature is measured at temperature and humidity measurement point WSsIt is if tested
Environment true temperature is T, then the temperature difference is between temperature and humidity measurement point WS and auxiliary temperature and humidity measurement point WS1：
Δ t=T1-Ts (1)。
Again due to fixing in humiture transducer space, extraneous factor is relatively uniform to its internal influence, and auxiliary humiture is surveyed
Relative position between amount point WS1 and temperature and humidity measurement point WS is fixed, therefore is met between test environment true temperature T and Δ t
Functional relation：
T=f (Δ t) ≈ K × Δ t+A (2),
Wherein K, A are constant, can be by being drawn in the actual test environment difference induction and conclusion of standard environment Imitating.
Acquiring test environment true temperature by formula (1) and (2) is：
T=K × (T1-Ts)+A (3)。
Installation wall humidity compensation method based on above-mentioned wall-mounted humiture transducer：If aid in temperature and humidity measurement point
It is RH that humidity is measured at WS11, since auxiliary temperature and humidity measurement point WS1 designs are in the edge of transmitter wiring hole 3, RH1
Wall humidity is approximately equal to, so RH1The humidity of installation wall is represented, if it is RH that humidity is measured at temperature and humidity measurement point WSSIf
The true humidity of test environment is RH, then psychrometric difference is between temperature and humidity measurement point WS and auxiliary temperature and humidity measurement point WS1：
Δ RH=RH1-RHS(4)；
Again due to fixing in humiture transducer space, extraneous factor is relatively uniform to its internal influence, and auxiliary humiture is surveyed
Relative position between amount point WS1 and temperature and humidity measurement point WS is fixed, therefore full between test environment true humidity RH and Δ RH
Sufficient functional relation：
RH=f (Δ RH) ≈ K ' × Δ RH+A ' (5),
Wherein K ', A ' are constant, can be by being drawn in the actual test environment difference induction and conclusion of standard environment Imitating；
Acquiring the true humidity of test environment by formula (4) and (5) is：
RH=K ' × (RH1-RHs)+A′ (6)。
This wall-mounted humiture transducer, by increasing an auxiliary temperature and humidity measurement point in interiors of products, with humiture
The measured value of measurement point is compared amendment, closer tested so as to compensate output to the test value of Temperature Humidity Sensor
The actual value of environment achievees the effect that compensation wall is damp and hot to transmitter environment measurement, is in dynamic in installation wall hygrothermal environment
State can in real time compensate humiture when changing, and test accuracy is high, solve existing wall-mounted humiture transducer to installation
Accuracy existing for the damp and hot compensation method of wall is low, implementation is poor, the deficiencies of cannot being compensated in real time to humiture.This practicality
Novel wall-mounted humiture transducer, in implementation process, without additionally debugging, suitable for all types of installation wall environment.
The above is only the preferred embodiment of the utility model, is not intended to limit the utility model, it is noted that
For those skilled in the art, on the premise of the utility model technical principle is not departed from, can also do
Go out several improvement and modification, these improvements and modifications also should be regarded as the scope of protection of the utility model.
