Having the beneficial effect that of technique scheme prevents, by sealed groove, leakage of supplying water.
Described turbine flowmeter also includes LCD display 10；
LCD display 10 is installed in effusion meter instrument 1 side, is used for showing water consumption.
Have wire inlet loop monitoring in collection in worksite device, important feeder line is monitored, contact loop is monitored and commonPath monitoring, the energy consumption platform applied for a patent, comprise about water consumption monitoring system: turbine flowmeter,Harvester, server platform, harvester is exactly Multifunctional collector: gathers turbine flowmeter, then gathersDevice is uploaded onto the server data base, and platform is the data display of data base out.
Turbine flowmeter connects harvester by 485 lines, gathers and sends data to clothes by netting twine TCP/IPBusiness device, data are carried out integrating and being displayed for inquiry by platform.
485 directly link turbine flowmeter, read turbine flow by the program in harvester and count, soThe information that rear parsing receives, is being transferred to server, by DLT 645-1997 protocol analysis character string,Obtaining data, DLT 645-1997 agreement is standard communication protocol.
As shown in figure 11, water consumption monitoring system, including: N number of turbine flowmeter, MCU controller,Memory element, crystal oscillator unit, power circuit, N >=1；
Each turbine flowmeter data transmission terminal connects MCU controller data receiving terminal, MCU controllerStorage communication ends connects memory cell data transmission ends, the water usage data that will be gathered by MCU controllerBeing stored by memory element, MCU controller crystal oscillator communication ends connects crystal oscillator unit communication end, MCUController power source end connects power subsystem feeder ear.
Technique scheme have the beneficial effect that the building that some turbine flowmeters are arranged in heavy construction every layerSpace water supply line output end of main, thus gather the output water yield value of pipeline, can after water yield value is gatheredAdding up accurately, thus obtain the overall water consumption of this heavy construction, the metering of this turbine flowmeter is more accurateReally, cost reduces, and without manned surveys, saves human cost.
Also include: the 1st turbine flowmeter data transmission terminal passes through to N turbine flowmeter data transmission terminalCAN controller carries out data transmission.
Having the beneficial effect that of technique scheme is transmitted controlling by CAN, and its data are transmittedMore stable.
Also include: network interface and cloud server；
MCU controller network data transmission terminal connects cloud server data receiver by network interface.
Water usage data is transferred to cloud service by network interface by having the beneficial effect that of technique schemeDevice, can remotely monitor water consumption service condition.
Also include LCD display unit；
MCU controller video data end connects LCD display unit data receiver.
