The electronic threshold switch and blower gear of pipe, to realize that control blower wind speed adjusts the purpose of room temperature.
Further, in temperature controller A at a distance from fan coil farther out when, such as careat is larger or temperature controller A
With fan coil not in same interior, if fan coil at this time operates normally, temperature controller A can be examined according to temperature sensor group B
The temperature data of the different port of survey and preset temperature value adjust room temperature, at this point, the temperature phase of fan coil return air inlet
When in current indoor temperature.
Main control module A1 is additionally configured to the current indoor temperature detected according to built-in detection unit 4, preset temperature value
Judge whether fan coil is faulty using scheduled algorithm with the temperature data of each port of fan coil and determines failure letter
Breath.
In the present embodiment, as shown in figure 3, temperature controller A according to the collected temperature value of detection unit 4 built in it come really
Room temperature before settled.Four temperature sensors in temperature sensor group B acquire the supply water temperature of fan coil respectively, return
Coolant-temperature gage, supply air temperature and return air temperature.This four temperature datas of temperature sensor group B acquisition are logical through temperature collecting module A3
It crosses 485 communication modes and is sent to main control module A1.Main control module A1 is by the temperature threshold of preset four ports of fan coil
Value range and real-time reception to four ports temperature data carry out sending after special calculation process respectively control signal to
Blower 32 controls electronic threshold switch and blower gear in turn, so that room temperature reaches the preset temperature value of terminal device C.Its
In, the temperature threshold range of four different ports of preset fan coil is pre-stored in main control module A1.In temperature
During degree adjustment, if blower 32 or water valve 31 break down, it is not up to standard all to will lead to room temperature.Such as it is known for water temperature
Degree, for example general summer supply water temperature, at 10 DEG C, after being installed on water valve due to supply water temperature sensor, temperature controller A, which is issued, to be beaten
After the order of heat water valve, supply water temperature does not still change or supply water temperature variation tendency very little (for example is reduced to from 28 DEG C
26 DEG C, just no longer change), do not reach the temperature threshold range of supply water temperature, at this moment, temperature controller A judge the appearance of water valve 31
Failure either water inlet line blocking etc., property need to carry out Measuring error in time.Assuming that the normal feelings of 31 work status of water valve
Under condition, after opening water valve 31 and blower 32, supply water temperature quickly reaches the temperature threshold range of supply water temperature, but blows temperature
Degree, return air temperature, room temperature does not change, or varies less, and does not reach corresponding temperature threshold range, temperature controller
A judgement is 32 failure of blower or air duct blocking, so that user can promptly and accurately repair, and avoid blower 32 or water
31 failure bring economic loss of valve, and reduce maintenance routing inspection cost.
As shown in Fig. 2, the normal operation in order to guarantee temperature controller A, the 220V power supply unit 8 in power module A2 is provided
220V alternating current.Wherein, power supply unit 8 provides 220V alternating current directly to execution unit 6.(the exchange/straight of circuit conversion unit 7
Stream translation circuit) by 220V alternating current be converted to lower direct current supply electricity to main control module A1, temperature collecting module A3 power supply.Its
In, it is built-in with reduction voltage circuit 3 and reduction voltage circuit 12 in main control module A1 and temperature collecting module A3, for power module A2 is defeated
DC voltage out is after reduction voltage circuit to built-in other module for power supply (such as NB-IOT wireless communication unit, first processing
Unit, the second processing unit etc.).For example, by 220V alternating current by be converted to after circuit conversion unit 7 12V DC voltage to
Main control module A1, temperature collecting module A3.Then main control module A1, temperature collecting module A3 pass through reduction voltage circuit 3 or 12 respectively
12V DC voltage is converted to the DC voltage of 3.5V or so afterwards to other built-in module for power supply.It should be understood that can also will drop

Pipe.Therefore, it can be achieved that multiple temperature controllers can be controlled simultaneously by a cell phone application or public platform, this is greatly facilitated
The management of property and company's administration.Meanwhile temperature controller can be controlled to adjust room temperature by mobile phone, and can pass through mobile phone control
The operation and shutdown of temperature controller processed, as shown in figure 5, mobile phone interface can show be presently in environmental information (such as temperature information, it is wet
Spend information and pollutant load etc.), user can select to adjust environment according to the experience of current body.For example, Current Temperatures are 20
DEG C, if sendible temperature is colder, " cold in the dust " may be selected and select preset temperature, then send this information, then temperature controller
Start to automatically adjust room temperature after receiving instruction.Alternatively, relevant options are selected when there is other demands, for example, opening or closing
Hull closure etc..This to control temperature controller adjusting room temperature more rapidly, and reaches energy-efficient purpose.
When fan coil breaks down, temperature controller is set through carrier network to terminal by NB-IOT wireless communication unit
Preparation send fault alarm and shows fault message.User can submit repairing information in cell phone application or public platform by this information.
As shown in fig. 6, selection report the relevant informations such as place and type for repairment after submit, this enable the related personnel such as property promptly and accurately
Acquisition fault message, quickly cope with failure problems, saved maintenance cost and reached energy-efficient effect.It should be understood that Fig. 5
It is only exemplary with the schematic diagram of the mobile terminal of Fig. 6, actual pages can be set according to different demands.
