Specific embodiment
In order to further explain the feature of the utility model, please refer to detailed description below in connection with the utility model with
Attached drawing.Institute's attached drawing is only for reference and purposes of discussion, is not used to limit the protection scope of the utility model.
As shown in Figure 1, present embodiment discloses a kind of heat supply water supply data acquisition devices, comprising: occupy utility meters 10, master control
Device 20, electronic switch 30 and NB circuit 40 processed；Master controller 20 by UART interface respectively with occupy utility meters 10, NB circuit 40
Connection；The I/O interface of master controller 20 is connect by electronic switch 30 with NB circuit 40, and electronic switch 30 is connected with power supply 50.
Wherein, occupying utility meters 10 includes water meter, ammeter, hotlist, gas meter etc..The acquisition of master controller 20 occupies in utility meters 10
Data, and data are transmitted to server by NB circuit 40, without wiring and external power supply, without devices such as concentrators,
Work progress is simple.Meanwhile master controller 20, electronic switch 30 and NB circuit 40 form low consumption circuit, master controller 20 is logical
The on/off that electronic switch 30 controls electric current in NB circuit 40 is crossed, in practical applications, what NB circuit 40 was periodically read occupies utility meters
When 10 data report to server, during NB circuit 40 reads data and uploads data, electronic switch 30 is closed, and is NB circuit
40 power supplies；After the completion of data report, the power supply power supply of NB circuit 40 is cut off by electronic switch 30, so that the electricity of NB circuit 40
Stream is 0, reduces current loss, the electric current of entire acquisition device is accomplished minimum.
As further preferred scheme, NB circuit 40 is connect by base station with server.And do not have to deployment radio network gateway,
It is directly transmitted using base station, reduces construction cost.
As further preferred scheme, the electronic switch 30 in the present embodiment uses AO3401, follow current 4.2A,
The power demands of NB circuit 40 can be met in normal work, while during data report, the electric current of whole device can be dropped
Down to 5uA or so.
