Description
Technical field
The utility model belongs to water meter and copies and accepts the apparatus structure technical field.
Background technology
Separated time system pulse water meter is concentrated and copied and accepted mode is that a kind of electronic water meter commonly used is copied and accepted mode, and it uses the electronic information technology to equip with arms standard machinery formula water meter, makes the standard machinery water meter become electronic water meter.Existing concrete data of water meter is copied and accepted process following (referring to Fig. 1): the magnetosensitive sensing device is installed on the water meter, can be converted into voltage pulse signal to the rotation of user's indicator of water gauge, these voltage pulse signals arrive collector by cable transmission, collector is responsible for gathering and measure the pulse signal from sensor of water meter, and is the pulse conversion of signals actual used water amount.Each water meter acquiring device can be gathered the data of some water meters simultaneously.Data concentrator is interconnected as main frame and each collector of water meter network, the responsible water meter water usage data of gathering in the collector of each dispersion is concentrated copied and accepted and is stored in its storer, uploads to long-range host computer or server by computer network, telephone network or wireless network at last.
Yet for a long time, it is indoor that domestic meter is installed in the user, and there is following shortcoming in separated time system centralized automatic meter-reading mode:
1, need to enter the user to the pulse signal-line of collector indoor for water meter, is not intended to easily or deliberately destroys;
2, to lay distance from user's water meter to collector to the pulse signal-line of collector longer for water meter, and pulse signal is easily disturbed to cause miscount;
3, the magneto sensor that is installed on the magneto-dependent sensor on the water meter adopts tongue tube to realize, in the time of near water meter magnetic pointer forwards tongue tube to, and the tongue tube adhesive, otherwise, in the time of near water meter magnetic pointer leaves tongue tube, tongue tube discharges, so just produced pulse signal.Yet, when the tongue tube closed and disconnected, can produce signal jitter, cause measuring mistake easily;
4, tongue tube damages easily, and the life-span differs greatly.The mechanical contact of tongue tube is in operating state for a long time, damages easily.The shell of tongue tube is very crisp, breaks because of vibration or other reason easily;
5, the collector of copying and accepting device of separated time system pulse water meter is before only gathered the single channel pulse transducer, so just may cause two kinds of situations to occur, and causes water consumption metering mistake.A kind of situation is: when near the water meter strong magnetic interference being arranged, cause the water meter pulse normally to export, cause few metering phenomenon; Another kind of situation is: when backwater during through water meter, the also normal output pulse signal of water meter pulse transducer causes many metering phenomenons;
Summary of the invention
The purpose of this utility model is the device of realizing that a kind of reliable and stable separated time system pulse water meter data centralization is copied and accepted.This device focuses on multi-user's water meter in the meter box, and to add triple channel on every water meter be the pulse transducer of core with the Hall switch element.The power lead of these pulse transducers and signal wire are interconnected with the relevant interface of collector respectively, have improved the shortcoming that the separated time system pulse water meter described in the technical background hurdle is concentrated the mode of copying and accepting.
Device of the present utility model is made up of meter box, water meter group and collector, it is characterized in that, is made up of meter box, water meter group and the collector that is connected, and wherein, every water meter of water meter group all adds the triple channel Hall element; Water meter acquiring device is made up of circuit board and last electronic components mounted thereof; Comprise by its function branch: Power Management Unit, sensor interface unit, microprocessor unit and communication unit; The triple channel signal wire of every sensor of water meter and power lead are interconnected with an interface of sensor interface unit respectively among the water meter group; One end of communication unit and the communication port of microprocessor unit are interconnected, and the other end is linked the outer data of meter box and copied and accepted network; The Power Management Unit that other circuit unit in collector and sensor of water meter provide electric energy is made up of battery and voltage transitions and mu balanced circuit; Sensor interface unit comprises several interfaces and pulse signal change-over circuit; A sensor of water meter among each interface and the water meter group is interconnected; And each interface comprises three pulse signal acquisition pin and two supply pins; Microprocessor unit is responsible for carrying out embedded program, is each circuit unit contact a complete functive; Communication unit one end links to each other with microprocessor unit, and the outer data of the other end and meter box are copied and accepted the network interconnection.
A magnet steel is installed on the some pointers in the water meter, three Hall elements in three Hall elements respectively at interval certain angle be placed in magnet steel and rotate near the formed circumference.In water meter, there are current out-of-date, the just and then rotation of pointer of magnet steel is installed.Like this, when magnet steel rotates a circle, three Hall elements are just by along triggering once, and every pulse signal-line is all exported a pulse signal successively.Collector comes the metering water meter water consumption by pulse pattern and the order discerned on these three pulse signal-lines.When the forward current were arranged in the water meter, collector added water consumption to respective meter, during anti-stream, then subtracted water consumption to respective meter.When high-intensity magnetic field occurring near the sensor, sensor middle distance two Hall elements far away will have the state that is in triggering level simultaneously, and this moment, collector was write down error condition, and when data are copied and accepted, uploaded state.
Microprocessor unit is converted into real water meter water usage data to it again by analyzing the pulse signal on each sensor of water meter pulse signal-line, is recorded in the storer in the microprocessor unit.Copy and accept when data and to issue in the network when copying and accepting order, microprocessor unit is sent to data by communication unit and copies and accepts network being recorded in its storer water usage data, finally uploads on the correlated digital equipment such as computing machine.
The utlity model has following advantage:
1, this device and water meter are installed in the meter box of regulation, are difficult for being damaged;
2, collector in this device and water meter all are installed in the same meter box, therefore do not exist pulse signal-line to pass by long and easy to be disturbed situation that occur;
3, this device is allowed use Hall and other active signal source, can avoid the tongue tube life problems;
4, this device connects triple channel pulse input, can effectively provide strong magnetic interference to report to the police.
5, this device connects triple channel pulse input, can effectively discern backflow phenomenon, and does corresponding subtraction counting or report when checking meter as warning message.
Further set forth the utility model content below in conjunction with Figure of description.
