Specific embodiment
Combined with specific embodiments below, the present invention is furture elucidated, and embodiment is under the premise of the technical scheme of the present invention
Implemented, it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.
Embodiment 1:
As shown in figures 1 to 6, the screen replacing warning device of the new blower of the permanent system of one kind three of the application, including control cabinet,
Monitoring center, the pressure sensor 3 being arranged at the strainer 2 of new blower 1, pressure sensor are separately positioned on the front side of strainer 2
With the air pressure of 2 front and back of rear side detection strainer, air velocity transducer 4, pressure sensor, wind speed sensing are additionally provided in new blower 1
Device, monitoring center connect with control cabinet respectively.
Control cabinet is the control cabinet of three permanent systems, and central processing unit is provided in control cabinet, and central processing unit and pressure pass
Sensor 3, air velocity transducer 4 connect.Central processing unit uses single-chip microcontroller, and the AT89S51 single-chip microcontroller of Atmel company can be used, and leads to
The pressure difference P that 2 front and rear sides of strainer are calculated in central processing unit is crossed, wind speed is measured by the air velocity transducer in blower 5
Fspeed has obtained the number of filter net jam degree Z by testing for a long time by pressure difference and wind speed the two major influence factors
It according to table, is being calculated in real time via central processing unit, is comparing, reach the chocking-up degree of real-time monitoring strainer 2, when reaching setting value
After alarm, remind user and engineer to replace strainer.
The replacement cycle of strainer not instead of a regular time, is influenced by factors, as outside air is clear
Clean degree and air pressure, rotation speed of fan, the resistance of ducting, blower case size etc..Here it is why strainer in different user man
Replacement cycle variant reason.The utility model brings these factors into two applicants by testing the public affairs obtained for a long time
The purpose of formula, first formula are Fspeed=f (x1, x2 ...), wherein x1, and x2 ... is disturbing factor, the formula is to pass through center
Processor, which first calculates, there emerged a wind speed correction coefficient, the pressure fan when normal work that wind speed compensation coefficient, that is, system at this calculates
The air speed value of system needs is further calculated in the mean wind speed of air-supply.Second formula is Z=Z (P, Fspeed), will
Do not stop to compare the corresponding data form of P and Fspeed by central processing unit, it can be deduced that 2 chocking-up degree digital representation of strainer,
After reaching the filter net jam degree excessive value that test obtains, system will be will call the police, and be reminded user and engineer to replace strainer, be saved
Artificial extraction strainer judges the trouble of service condition, realizes strainer intelligently replacement alarm technique.
Pressure sensor 3 includes first pressure sensor 31 and second pressure sensor 32,31 He of first pressure sensor
The probe of second pressure sensor 32 is separately positioned on front side and the rear side of strainer 2, first pressure sensor 31 and second pressure
Sensor 32 is connect with central processing unit, and central processing unit is measured by first pressure sensor 31 and second pressure sensor 32
Pressure value calculate the pressure difference P of the front and back of strainer 2.
First pressure sensor 31 and second pressure sensor 32 are using diffusion silicon pressure sensor or ceramic pressure drag pressure
Force snesor, as shown in Figure 5.Diffusion silicon pressure sensor is that impressed pressure is passed by the silicone oil of stainless steel diaphragm, inner sealing
It is delivered on sensitive chip, sensitive chip is not directly contacted with measured medium.Height is exported with its sensitivity, dynamic response is good, measurement essence
Degree is high, and stability is good, is easy to minimize, and is conveniently applied in the three new blowers of permanent system.
The air outlet side of pressure fan 5 is arranged in air velocity transducer 4, and air velocity transducer 4 is sensed using pitot tube type wind speed
Device, hot-wire array sensor, propeller air velocity transducer, Hall effect electromagnetism air velocity transducer or ultrasonic wind speed sensing
Device etc..For example, by using the AVDT25 wind speed transducer of the auspicious crystalline substance REGIN of Sweden.
Monitoring center connect with the mobile terminal that maintenance staff are held, and filter net jam data are transmitted in monitoring by control cabinet
The heart, and it is transmitted to the mobile terminal of maintenance staff.It alarms after reaching setting value, user and engineer is reminded to replace filter
Net.It is provided with warning device in control cabinet, when strainer needs replacing, is reminded, or can also be by being connect with control cabinet
The clean-up performance of master control screen real-time display strainer reminded when strainer needs replacing.
Embodiment 2:
The content identical as the basic content of embodiment 1 of embodiment 2, the difference is that the setting of pressure sensor 3 is different, this reality
The pressure sensor 3 for applying example uses a micro-pressure-difference transmitter, and micro-pressure-difference transmitter includes low pressure port 33 and high-pressure mouth 34, installation
When, high-pressure mouth 34 is connected to the front side of strainer 2, and the rear side of strainer is arranged in low pressure port 33.Micro-pressure-difference transmitter directly measures filter
The pressure difference P of front and back is netted, micro-pressure-difference transmitter is connect with central processing unit, does not stop to compare P and Fspeed pairs by central processing unit
The data form answered, it can be deduced that filter net jam degree digital representation, after reaching the filter net jam degree excessive value that test obtains,
System will will call the police, and user and engineer is reminded to replace strainer.
Micro-pressure-difference transmitter uses LFM108 micro-pressure-difference transmitter or TRD-150 wind pressure transmitter.LFM108 micro-pressure-difference
Transmitter is suitable for the measurement of air or neutral gas, detects differential pressure or gauge, and this pressure difference is converted to proportional
Electricity output.LFM108 has the high level output of 0~5/10VDC or 4~20MA, is suitable for Heating,Ventilating and Air Conditioning (HVAC), energy source capsule
Reason system, VAV and fan control, environment pollution control static state pipeline and clean chamber pressure, fume hood control, baking oven pressurization and furnace
The fields such as Ventilation Control.The range of TRD-150 wind pressure transmitter is 0-0.06~± 100kpa, measures non-conductive free from corrosion Jie
Matter can be used for pressure difference, pressure, negative pressure measurement simultaneously, can satisfy the use of new blower fan screen net, and shape is exquisite, can easily pacify
At the strainer of new blower, when surveying clean gas, high-pressure mouth and low pressure port can be installed towards any direction.Survey moist, visceral-qi
When body, interface is necessarily perpendicular to ground installation.
