Description
Technical field
The utility model belongs to metering field, and in particular to a kind of electromagnetism that super low-power consumption is realized by intelligent dormant technology
Flowmeter.
Background technology
Battery powered electromagnetic flowmeter needs that electromagnetic flowmeter operating power consumption is greatly reduced.Traditional low power consumption electromagnetic
Flowmeter uses low consumption circuit and low-power consumption IC except electric circuit and display, is also exactly to reduce exciting current and gap is adopted
The technology of sample realizes low-power consumption.But gap this scheme of sampling can lose certain measurement accuracy.
Utility model content
In order to solve above-mentioned technical problem present in prior art, the utility model provides a kind of Low-power-consumptiodormancy dormancy electricity
Magnetic flowmeter, including：MCU circuits, sample circuit, excitation control circuit, empty pipe detection circuitry, display circuit, touch key-press, institute
Sample circuit is stated, excitation control circuit, empty pipe detection circuitry, display circuit, touch key-press is connected with MCU circuits respectively, described
MCU circuits use MKM34Z128CLL5 low power processors；The display circuit uses low-power consumption LCD；The touch key-press is adopted
IC is touched with CY8C20140-SX2I；The excitation control circuit uses super low-power consumption MOSFET.
The utility model is analyzed by the dynamic analysis to flow and the intelligence and dynamic of blank pipe full packages.There are the feelings of flow
Under condition in the case of flowed fluctuation is smaller or compares smoothly, system increases the sampling interval automatically, to reduce power consumption.Otherwise such as
The normal low-power consumption mode of fruit flow big ups and downs switchback.If the system detects that 0 flow or empty pipe condition, system shutdown excitation electricity
Stream arrives until normal discharge signal.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As illustrated in fig. 1 and 2, Low-power-consumptiodormancy dormancy electromagnetic flowmeter of the present utility model, including：MCU circuits 1, sample circuit
2, excitation control circuit 3, empty pipe detection circuitry 4, display circuit 5, touch key-press 6, sample circuit 2, excitation control circuit 3 is empty
Pipe detects circuit 4, and display circuit 5, touch key-press 6 is connected with MCU circuits 1 respectively.
As shown in figure 3, MCU circuits 1 use MKM34Z128CLL5 low power processors, sampled, shown, excitation control
The realization of the intelligent function such as system and traffic trends judgement.
Sample circuit 2 is sampled to electrode signal, and then obtains flow and changes in flow rate trend.
As shown in figure 4, display circuit 5 is shown using low-power consumption LCD can realize intelligent display and closing.
As shown in figure 5, touch key-press 6 is using touch IC（CY8C20140-SX2I）Induced key partition capacitance changes messenger
Machine interactive operation.Enter optimization low-power consumption mode comparing system when long-time is not operated（Such as close display reduction CPU works
Working frequency etc.）.
As shown in fig. 6, excitation control circuit 3 is controlled using super low-power consumption MOSFET (FDN327N) by the intelligence of MCU circuits 1
The switch of magnet exciting coil 7 processed carries out precise controlling and the management of power with clearance control, when flowed fluctuation is big, increases electric current.
As shown in fig. 7, empty pipe detection circuitry 4 is to electrode signal dynamically analysis and the pre- judgement of trend.If passing through electrode
The amplitude of variation and rate of change size of signal judge that flowed fluctuation diminishes by increasing sampling interval reduction power consumption but energy fully
Ensure the precision of sampling；If it is determined that the fluctuation to flow has the trend of increase to reduce in the case where controlling magnet exciting coil power
Excitation interval ensures precision.Minor swing and steady flow amount situation account for the ratio of whole operating mode in the case of actual flowed fluctuation
Example is that comparison is high.Can highly effective reduction Overall Power Consumption by this measure.
If the system detects that flow is zero within the long time.System will turn off excitation and enter super low-power consumption
Pattern（The monitoring of flow signal is only kept to recover sampling when there is flow）.
When empty pipe detection circuitry 4 determines empty pipe condition, system will further decrease power consumption（Close flow signal prison
Control）, until pipeline is restored to the common low-power consumption mode of full packages.
