Further, given threshold time, the given threshold time are longer than the predetermined time.
Further, when throughput average value is more than setting percentage lower than early warning value within the given threshold time,
Then it is determined as that electric machine assembly air inlet blocks.
Further, when throughput average value is lower than setting percentage lower than early warning value within the given threshold time,
Then the threshold time recalculates.
Further, the predetermined time is shorter than the threshold time of the setting.
Further, process instruction includes that control dust catcher adjusts working condition.
Further, process instruction includes the control instruction that control issues alarm signal.
A kind of dust catcher air flow detecting device, including flow sensor, controller, the flow sensor and the control
Device processed carries out data docking, for detecting the throughput of electric machine assembly air inlet, and will test data and is sent to the control
Device, the controller are lower than the early warning for calculating predetermined time interior air-flow amount average value, and in the throughput average value
When value, process instruction is issued.
A kind of dust catcher, including electric machine assembly and above-mentioned dust catcher air flow detecting device, the flow sensor is set
It is placed in the air inlet of electric machine assembly.
It further, further include warning device, the warning device is connect with dust catcher air flow detecting device signal, is used
In the process instruction for receiving controller sending.
Further, warning device is set on dust catcher.
Further, warning device includes the intelligent terminal being wirelessly connected with dust catcher.
The present invention provides a kind of dust catcher air-flow quantity measuring method, acquires the air-flow of motor of dust collector component air inlet
Amount；Predetermined time interior air-flow amount average value is calculated, and is compared with setting early warning value, whether judges the throughput average value
Lower than early warning value；When the throughput average value is lower than the early warning value, process instruction is issued, is realized to motor of dust collector group
The detection of part upstream air duct flow is adjusted when air duct dust accumulation is more or its flow is caused to reduce even zero for blocking by feedback
Section reduces power or the shutdown of motor, reaches the protection under abnormality to dust catcher and its motor.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of dust catcher；
Fig. 2 is the flow chart of dust catcher air-flow quantity measuring method.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, is clearly and completely retouched to the technical solution in the present invention
It states, it is clear that the described embodiments are merely a part of the embodiments of the present invention, instead of all the embodiments.
As shown in Figure 1, a kind of dust catcher air flow detecting device, including flow sensor 1, controller 2, the flow pass
Sensor 1 carries out data with the controller 2 and docks, and for detecting the throughput of electric machine assembly air inlet, and will test data
It is sent to the controller, the controller is averaged for calculating predetermined time interior air-flow amount average value, and in the throughput
When value is lower than the early warning value, process instruction is issued.
As shown in Figure 1, a kind of dust catcher, including electric machine assembly 3, above-mentioned dust catcher air flow detecting device, alarm dress
4 are set, the flow sensor 1 is set to the air inlet of electric machine assembly 3；The warning device 4 is detected with dust catcher throughput
Device signal connection, for receiving the process instruction of the sending of controller 2.
Warning device is set on dust catcher, such as signal lamp, voice broadcasting system, passes through signal lamp flashing or voice broadcast
Remind user；Or warning device includes the intelligent terminal being wirelessly connected with dust catcher, dust catcher connects network, cell phone application, control
The signal of device can be issued by cell phone application, remind user；It realizes under abnormality, control module feeds back abnormal signal, and then not
Power of motor with degree is reduced until relationship, avoids motor temperature rise is excessively high from burning.
As shown in Fig. 2, a kind of dust catcher air-flow quantity measuring method,
S1: the throughput of acquisition motor of dust collector component air inlet；
Flow sensor is set in the upstream air duct of motor of dust collector component, for acquiring, detecting the stream at this in real time
Collected real-time flow data is sent to controller module and handled by magnitude n, flow sensor；
S2: predetermined time interior air-flow amount average value is calculated, and is compared with setting early warning value, judges that the throughput is flat
Whether mean value is lower than early warning value；
Namely control module is by flow value n1, n2, n3 ... in the 1s time, and the stream being calculated in this time
Average value N is measured, prevents dust catcher from judging by accident；Control module judges the size relation of flow value N Yu early warning value Nn；If N >=Nn,
Then dust catcher state is normal；If N < Nn, dust catcher abnormal state；
The threshold time of given threshold time, the setting are longer than the predetermined time, as the predetermined time be 1s when, given threshold
Time is 1min, and whether statistics 1min interior air-flow amount average value is more than setting percentage lower than early warning value；
When throughput average value within the given threshold time lower than early warning value lower than setting percentage when, then the threshold
The value time is recalculated；
S3: when the throughput average value is lower than the early warning value, process instruction is issued；
When throughput average value is more than setting percentage lower than early warning value within the given threshold time, then it is determined as
The blocking of electric machine assembly air inlet, issues process instruction；
Process instruction includes controlling dust catcher to adjust the power or dust catcher shutdown that working condition includes adjusting reduction motor；
Or control issues the control instruction of alarm signal, user is reminded such as in the form of signal lamp or by dust catcher
Voice system reminds user, reaches the protection under abnormality to dust catcher and its motor.
The present invention is calculated in the predetermined time and is put down in air duct by the detection to motor of dust collector component upstream air duct flow
Equal throughput improves the detection accuracy of dust catcher, prevents erroneous judgement situation, when air duct dust accumulation is more or blocking causes its stream
When amount reduces even zero, power or the shutdown of motor are reduced by feedback regulation, reach under abnormality to dust catcher and its
The protection of motor.
It above are only preferred embodiment of the invention, but the design concept of the present invention is not limited to this, all benefits
It is made a non-material change to the present invention, should all be belonged to behavior that violates the scope of protection of the present invention with this design.
