Description
Technical field
This utility model belongs to intellectual water meter technical field, concrete for a kind of control system for water meter.
Background technology
The existing intellectual water meter of China can be divided into pre-payment water meter and remote transmitting water meter.Wherein pre-payment water meter is divided into TC card water meter, TM card water meter, IC Card Water-Instrument, Code water-meter, and these water meters are general only equipped with lithium ion battery, or only equipped with aneroid battery, consume energy very much, and battery reserve of electricity is the most limited, cannot use when exhausting again；Wherein remote transmitting water meter is divided into impulse type remote communication water meter, direct reading remote watermeters, and these water meters use alternating current power supply, and typically cannot work under power-off condition.
And the most do not use clean energy resource solar energy, in the case of solar energy is not enough, just use the control system for water meter of stand-by power supply；So being badly in need of one both environmental protection and energy saving on market, saving again on and off switch hardware cost, improving the product of on and off switch motility.
Utility model content
Goal of the invention of the present utility model is: in order to solve water meter power consumption and the problem without stand-by power supply in prior art, or solve water meter and have stand-by power supply, but power supply is not environmentally, on and off switch hardware cost is high and the inflexible problem of on and off switch, the utility model proposes a kind of control system for intellectual water meter.
The technical solution of the utility model is: a kind of control system for intellectual water meter, including: sun-generated electric power, power-supply system, stand-by power supply, the first transistor, transistor seconds, third transistor, not gate, single-chip microcomputer；Described sun-generated electric power one end ground connection, the other end is connected with the source electrode of the first transistor；The grid of described the first transistor exports with the A end of single-chip microcomputer and is connected, and drain electrode is connected with power-supply system；Described not gate input is connected with Chip Microcomputer A end, and outfan is connected with transistor seconds grid；The drain electrode of described transistor seconds is connected with power-supply system, and source electrode is connected with one end of stand-by power supply；The other end ground connection of described stand-by power supply: the grid of described third transistor is connected with the B end of single-chip microcomputer, and source electrode is connected with power-supply system, drain electrode is connected with operational module water meter.Preferably, described the first transistor, transistor seconds, third transistor are NMOS tube.
The beneficial effects of the utility model are: this system makes water meter use sun-generated electric power under normal conditions, use stand-by power supply, it is achieved that environmental protection and energy saving in the case of solar energy is not enough.This system passes through single-chip microcomputer high level and low level control, it is achieved that the on-off control to operational module.This system is also by single-chip microcomputer high level and low level control simultaneously, it is achieved that the switching of clean energy resource sun-generated electric power to stand-by power supply, saves on and off switch hardware cost, improves on and off switch motility.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of control system for intellectual water meter, including: sun-generated electric power, power-supply system, stand-by power supply, the first transistor, transistor seconds, third transistor, not gate, single-chip microcomputer；Described sun-generated electric power one end ground connection, the other end is connected with the source electrode of the first transistor；The grid of described the first transistor exports with the A end of single-chip microcomputer and is connected, and drain electrode is connected with power-supply system；Described not gate input is connected with Chip Microcomputer A end, and outfan is connected with transistor seconds grid；The drain electrode of described transistor seconds is connected with power-supply system, and source electrode is connected with one end of stand-by power supply；The other end ground connection of described stand-by power supply: the grid of described third transistor is connected with the B end of single-chip microcomputer, and source electrode is connected with power-supply system, drain electrode is connected with operational module water meter.
Described the first transistor, transistor seconds, third transistor are NMOS tube.
Below in conjunction with above-mentioned particular circuit configurations, the operation principle for the control system of intellectual water meter of the present utility model is described further.
When main power source is normal, the A end output high level of single-chip microcomputer, the first transistor turns on, and transistor seconds ends so that sun-generated electric power is powered to power-supply system, and stand-by power supply is not powered.When single-chip microcomputer detects that sun-generated electric power occurs under-voltage, the A end output low level of single-chip microcomputer, the first transistor ends, and transistor seconds turns on so that stand-by power supply is powered to power-supply system, and sun-generated electric power is not powered.It is achieved thereby that sun-generated electric power purpose of switching flexibly under undervoltage condition.
When operational module water meter needs work, the B end output high level of single-chip microcomputer, third transistor turns on, and operational module water meter works under power-supply system effect；When operational module water meter need not work, the B end then output low level of single-chip microcomputer, third transistor cut-off, operational module water meter quits work.This achieves the switch of operational module water meter, saves the energy.
Concrete control realization of the present utility model is prior art, and this utility model only provides system structure design technical scheme.
These are only preferred embodiment of the present utility model; it is not intended to limit protection domain of the present utility model; therefore, all any modification, equivalent substitution and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
