Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of central air-conditioning intelligence detecting system.
Detailed description of the invention
As it is shown in figure 1, a kind of central air-conditioning intelligence detecting system that Fig. 1 is the present invention to be proposed.
Reference Fig. 1, the central air-conditioning intelligence detecting system that the present invention proposes, including: temperature setting unit, temperature detection list
Unit, feedback unit, control unit；
Temperature setting unit, for gathering time point and the default temperature in this room that each room central air-conditioning brings into operation
Angle value T01、T02、T03、T04……T0n；Said temperature setup unit also includes display screen, and control unit obtains each room respectively
Preset temperature value and the actual temperature value in this room, and above-mentioned preset temperature value and actual temperature value transmission are carried out to display screen
Display；Temperature in room can be watched by user by display screen, and the actual temperature value in finding room is long-time all
When not reaching preset temperature value, user can be reflected to related personnel in time, in order to professional is in time in this room
Central air-conditioning overhauls, it is ensured that the convenient use of user.
Temperature detecting unit, is used for gathering each room central air-conditioning and brings into operation t1The actual temperature in this room after time
Angle value T11、T12、T13、T14……T1n；In detected room, central air-conditioning is in normal work, above-mentioned t1Time
Be enough to make the actual temperature change in detected room to preset temperature value, so can get rid of central air-conditioning run the time shorter and
Cause refrigeration or the unconspicuous interference of heating effect.
Temperature detecting unit utilizes temperature sensor to gather the actual temperature value in each room；And can be provided with in each room
Multiple temperature sensors, then in the actual temperature value in this room is this room, the detected value of all temperature sensors is average
Value；It is arranged such, the actual temperature value in each room can be gathered accurately, it is to avoid cause more greatly collection due to room
The inaccurate problem of actual temperature value, is conducive to whether the central air-conditioning in each room is existed fault and detects.

Centre air-conditioning is after running the equal time, and the actual temperature value in j room is well below actual temperature value in i room, i.e. j room
Central air-conditioning there may be and heat fault, now control unit instruction controls feedback unit by the room identification in this room and system
Hot stall information sends to background work personnel；If T1j>3T0j/ 4, show that the heating effect of the central air-conditioning in j room is failed to understand
Aobvious, whether there is fault for the central air-conditioning in checking j room, continue to allow the central air-conditioning in this room run a period of time,
Bring into operation t at this room central air-conditioning3After time, control unit obtains actual temperature value T in this room again1j", and compare
T1j" and 5T0jThe magnitude relationship of/6, above-mentioned t2Time is more than the t of twice1Time, to ensure the abundance of time, if T1j”≤
5T0j/ 6, after showing that in j room central air-conditioning runs the long period, the actual temperature value in this room still with preset temperature
Value difference is relatively big, then the central air-conditioning in this room there may be and heats fault, and now control unit instruction controls feedback unit will
The room identification in this room sends to background work personnel with heating fault message；Be conducive to staff in time in this room
Central air-conditioning carries out fault detect.
Wherein, T0jPreset temperature value, T for j room1jBring into operation t for central air-conditioning in j room1Reality after time
Temperature value, T1j' bring into operation t for central air-conditioning in j room2Actual temperature value after time, T1j" it is central air-conditioning in j room
