Abstract
The utility model discloses an optoelectronic direct reading M-BUS remote transmission intelligent water meter, which comprises a water meter valve, a valve power switch, an optoelectronic direct reading module, an optoelectronic collecting plate and a microprogrammed control unit (MCU) and further comprises a valve drive circuit and a plugging rotation detection circuit. The valve drive circuit and the plugging rotation detection circuit are connected with the MCU which is connected with the valve power switch, and the MCU controls the valve drive circuit, detects signals of the plugging rotation detection circuit, and controls the valve power switch to control the water meter valve to turn on and off. The optoelectronic direct reading M-BUS remote transmission intelligent water meter can control the water meter valve to turn on and off by controlling the valve power switch in a long-distance mode, remind users to timely pay money by closing the valve, and enable the management to be more scientific and initiative.
Description
Technical field
The utility model relates to a kind of photo-electronic directly reading M_BUS teletransmission intellectual water meter.
Background technology
Mainly form based on the M-BUS teletransmission intellectual water meter of photo-electronic directly reading technology at present by base table and photoelectricity collection plate; Wherein base table has water meter valve, photo-electronic directly reading module, and the photoelectricity collection plate has MCU and photo-electronic directly reading control module, because photo-electronic directly reading is the information of directly gathering the gauge outfit character wheel; Circuit module must embed in the gauge outfit character wheel; Gauge outfit and valve are two independent sectors, can't use a circuit board to realize valve and two functions of data acquisition, and former photo-electronic directly reading water meter all is not to be with valve control function; This water meter can his-and-hers watches reading carry out teletransmission; Can not cut off the water by valve-off but be in arrears with the user under the situation of water rate, thereby make management work start from passive situation, can't effectively handle the arrearage situation.
The utility model content
It is a kind of with the photo-electronic directly reading M_BUS teletransmission intellectual water meter that can control valve switch that the utility model provides.
This photo-electronic directly reading M_BUS teletransmission intellectual water meter that the utility model provides; Comprise water meter valve, valve power switch, photo-electronic directly reading module, photoelectricity collection plate, MCU; Also comprise valve driving circuit and stall testing circuit, valve driving circuit is connected with MCU with the stall testing circuit, and MCU is connected with the valve power switch; By MCU by-pass valve control driving circuit and detect the stall circuit signal, the by-pass valve control power switch is controlled the break-make of water meter valve.
Said MCU adopts two, and one is that secondary MCU is used to control the photoelectricity collection plate and carries out data acquisition, and one is that main MCU is used for being responsible for correspondence with foreign country, uses serial communication mode to carry out exchanges data between the major-minor MCU.Said valve driving circuit mainly contains six switching tubes to be formed, and adopts a type bridge-type structure.Said stall testing circuit mainly is made up of positive and negative two stall detection transistor.
The utility model is owing to increased valve driving circuit and stall testing circuit on existing photo-electronic directly reading M_BUS teletransmission intellectual water meter; Detection transistor has very big electric current in the time of the valve stall; MCU detects the IO mouth and high electricity occurs, with the valve-off power switch, thereby plays the effect of controlling water meter valve closing or unlatching; Can remind the user to pay the fees through closing the water meter valve to the arrearage family thus on time, make and manage science and active more.
Description of drawings
Fig. 1 is that M_BUS valve control teletransmission intellectual water meter is formed structural representation.
Fig. 2 is the valve driving schematic diagram.
Embodiment
As can beappreciated from fig. 1 the utility model comprises master control borad and electro-optical package.Because water meter structure and space limit, adopt two MCU frameworks, two MCU use serial communication mode to carry out exchanges data.Main MCU is responsible for correspondence with foreign country, the power supply power supply of each module, valve control and detection etc.Secondary MCU be control electro-optical package carry out data acquisition, with main MCU be serial communication.Because main MCU correspondence with foreign country also needs a serial ports,, main MCU adopt IO mouth simulative serial port to realize so communicating by letter with secondary MCU.Master control borad comprises power supply unit, main MCU, valve driving circuit unit.Power supply unit is the total system power pack, comprises M_BUS receiving chip (TSS721A), and to the high-level efficiency BUCK chip (LM5007) of valve power supply.Main MCU is a water meter master process chip, has adopted up-to-date little power consumption, VLSI chip Atmega48PA as master chip.Valve driving circuit is to adopt a type bridge-type structure, the common-mode phenomenon can not occur.Secondary MCU be control electro-optical package carry out data acquisition, with main MCU be serial communication.Because main MCU correspondence with foreign country also needs a serial ports,, main MCU adopt IO mouth simulative serial port to realize so communicating by letter with secondary MCU.
As can beappreciated from fig. 2 valve driving by 6 switching tubes form (V11, V13, V14, V15, V17, V18).When having only the V11 conducting, V14, just conducting of V18, when having only the V17 conducting, V13, just conducting of V15, this structure does not have the common-mode phenomenon with respect to the H bridge, so need not consider the actuation time of switching tube.V10, V16 are the positive and negative stall detection transistor of valve, in the time of the valve stall, have very big electric current; And cause V14, V15 to be in magnifying state, as this triode Vce during greater than 0.7V; V10, V16 will conductings, and main MCU is as long as judge in the switch valve process whether detect the IO mouth high level occurs; Valve-off power switch at once occurs behind the stall, prevent to drag down bus voltage and cause system to be in abnormal work., valve has an instantaneous large-current when starting, so behind Open valve, need the time-delay certain hour just to judge.Because V10, V16 not conducting is a high-impedance state, can adopt line or mode, only needs to detect with an IO mouth.
