An embodiment of the present invention provides a kind of 7 fault handling method of high pressure sensor, applied to humidity control system 1, uses
In the method that after the failure of high pressure sensor 7, actual measurement high-voltage value is replaced with the virtual high-voltage value being calculated so that temperature
Degree regulating system 1 still can continue to work normally.Referring to Fig. 2, at 7 failure of high pressure sensor provided in an embodiment of the present invention
The flow chart of reason method.7 fault handling method of high pressure sensor includes：
Step S301：Obtain multigroup operating parameter and multiple second that the first temperature adjustment module is in different time points
Second actual measurement high-voltage value of temperature adjustment module.
It should be noted that every group of operating parameter is used to react the first temperature adjustment when gathering this group of operating parameter
The operating status of module.And every group of operating parameter include outdoor environment temperature, the first actual measurement high-voltage value, condenser into tube temperature
Degree, outlet pipe temperature.
In addition, the inlet pipe temperature of condenser, outlet pipe temperature, outdoor environment temperature, the first actual measurement high-voltage value are respectively first
The first temperature sensor 4, second temperature sensor 5, three-temperature sensor 6 and the high pressure sensor 7 of temperature adjustment module
Gather and transmit；Second actual measurement high-voltage value is gathered and transmitted for the high pressure sensor 7 of second temperature adjustment module.
Step S302：Based on multigroup outdoor environment temperature, first actual measurement high-voltage value, condenser inlet pipe temperature, go out tube temperature
Degree calculates the first proportionality coefficient and the second proportionality coefficient.
Specifically, the first proportionality coefficient and the second proportionality coefficient can be calculated by following formula respectively：
M=(Tout1*Tc2-Tout2*Tc1)/(Tin2*Tout1-Tin1*Tout2)
N=(Tout1*Tc2-Tout2*Tc1)*(Tin1-Tin2)/(Tin2*Tout1-Tin1*Tout2)/(Tout1-Tout2)
Wherein, m is the first proportionality coefficient, and n is the second proportionality coefficient, Tout1、Tin1And Tc1Respectively the first moment into
Tube temperature degree, outlet pipe temperature and the first actual measurement high-voltage value, Tout2、Tin2And Tc2Inlet pipe temperature, the outlet pipe at respectively the second moment
Temperature and the first actual measurement high-voltage value.
It is to be appreciated that the first actual measurement high-voltage value is homogeneously associated with inlet pipe temperature and outlet pipe temperature, and meet in theory

With reference to coefficient, τ is outdoor environment temperature, TinFor inlet pipe temperature, ToutFor outlet pipe temperature.
When due to the first proportionality coefficient and the second proportionality coefficient being based on the first temperature adjustment module normal operation
Parameter be calculated, in conjunction with the current operating parameter of the first temperature adjustment module, i.e., current inlet pipe temperature, outlet pipe temperature
Just the virtual high-voltage value under current state can be calculated, which is actually the reason that high pressure sensor 7 should be measured
By high-voltage value.
Step S305：Virtual high-voltage value is corrected based on the multiple second actual measurement high-voltage values.
To avoid the deviation of virtual high-voltage value that calculates excessive, thus by the multiple second actual measurement high-voltage values to virtual high
Pressure value is modified so that the virtual high-voltage value for finally replacing the first actual measurement high-voltage value can more meet it is actual, more accurate,
The first actual measurement high-voltage value that more fitting high pressure sensor 7 should actually measure.
Referring to Fig. 3, the particular flow sheet for step S305.

Value.
Maximum actual high-voltage value and minimum actual high-voltage value are selected from the multiple second actual measurement high-voltage values, so that it is determined that empty
Intend the scope of high-voltage value.

S3053；If it is not, then perform sub-step S3054.
Sub-step S3053：Virtual high-voltage value is replaced with maximum actual high-voltage value.
When virtual high-voltage value is more than maximum actual high-voltage value, with the maximum actual high-voltage value of closest virtual high-voltage value
As new virtual high-voltage value, so that more to meet reality also more accurate for new virtual high-voltage value.
Sub-step S3054：Judge whether virtual high-voltage value is less than minimum actual high-voltage value, if it is, performing sub-step
S3055；If it is not, then perform sub-step S3056.
Sub-step S3055：Virtual high-voltage value is replaced with minimum actual high-voltage value.
When virtual high-voltage value is less than minimum actual high-voltage value, with the minimum actual high-voltage value of closest virtual high-voltage value
As new virtual high-voltage value, new virtual high-voltage value is equally set more to meet reality also more accurate.
Sub-step S3056：Keep virtual high-voltage value constant.
When virtual high-voltage value is greater than or equal to minimum actual high-voltage value and is less than or equal to maximum actual high-voltage value, show
Virtual high-voltage value, at this time without change, keeps virtual high-voltage value constant in normal range (NR).
Step S306：Revised virtual high-voltage value is substituted into the first actual measurement high-voltage value to maintain the first temperature adjustment module
Normal work.
First actual measurement high-voltage value is substituted by revised virtual high-voltage value, virtual high-voltage value is transmitted to processor 2, is made
First temperature adjustment module and humidity control system 1 being capable of normal operations.
Step S307：Reduce priority of first temperature adjustment module in humidity control system 1.
Usually, humidity control system 1 includes multiple temperature adjustment modules 3, works when only needing a temperature adjustment module 3
During with regard to that can meet the needs of users, processor 2 would generally control the temperature adjustment module 3 of highest priority to run to adapt to user
Demand；Thus after the first temperature adjustment module breaks down, the priority level of the first temperature adjustment module is turned down, can
To avoid when humidity control system 1 only needs a temperature adjustment module 3 to work, processor 2 controls the first temperature adjustment module
Run and cannot meet the situation of user demand.
