Fig. 1 is a kind of schematic diagram with gas meter, flow meter of double-counting structure.
Embodiment
Referring to Fig. 1, a kind of gas meter, flow meter with double-counting structure, its inner metering circuit mainly is made up of power supply, microprocessing unit and counting unit.Above-mentioned counting unit comprises tongue tube, photo-electronic directly reading module and counting code-disc.
The counting code-disc is made of fixed support and 2 character wheels at least, and coaxial linking to each other of the central rotating shaft of these character wheels is installed on the fixed support, and forms at least one integer-bit code word and at least one decimal place code word side by side.On the anchor ring of one of them of above-mentioned character wheel magnet is installed.The N utmost point of magnet is parallel with the bearing of trend of the magnetic red sheet of tongue tube with the line direction of the S utmost point.Magnet can be installed on any one character wheel of counting code-disc, but considers that the main effect of tongue tube is to produce trigger pip, and therefore in the utility model, the character wheel that magnet is installed is the character wheel that is positioned at integer-bit code word place.Because the magnetic red tablet quality of tongue tube is light, only less magnetic force of needs just can be with its adhesive, therefore described magnet is the plates that are embedded in the annulus surface of counting code-disc, so namely can satisfy the magnetic demand, the weight of the sum counter that also can reduce cost.The shape of magnet then can design accordingly according to the size of counting sabot, as being circular piece or square plate or strip piece.All offer the light tank that at least one axially connects on the anchor ring of each character wheel.
Tongue tube is fixed on the side of the character wheel that magnet is installed, when the magnet of character wheel forwards to over against tongue tube, and the magnetic red sheet closure of tongue tube inside.Because magnet and tongue tube are when carrying out parallel installation, the adhesive district of tongue tube is directly proportional with the length of the magnetic red sheet of tongue tube, therefore the magnetic red leaf length of the tongue tube described in the utility model length that should equal or be longer than magnet, i.e. length between the N utmost point of magnet and the S utmost point two ends.In the utility model preferred embodiment, the magnetic red leaf length of tongue tube is longer than the N utmost point of magnet and the length between the S utmost point two ends, can reduce the installation difficulty of magnet or tongue tube like this, and guarantees the reliability of adhesive.On circuit connected, tongue tube one end linked to each other with power cathode, and the other end of tongue tube is divided into two-way, and one the tunnel links to each other with positive source through resistance, and another road links to each other with the trigger pulse end of microprocessing unit.
The photo-electronic directly reading module is made up of counting drive plate and 2 pairs of infrared counting groups at least.Corresponding 1 character wheel of the every pair of infrared counting group, i.e. infrared transmitting tube in the 1 pair of infrared counting group and the infrared receiving tube anchor ring both sides that are oppositely arranged on corresponding character wheel.When the light tank on the corresponding character wheel turned between infrared transmitting tube and the infrared receiving tube, the Infrared of infrared transmitting tube emission can be passed this light tank and be received by infrared receiving tube.In the utility model, the quantity of the light tank of offering on described each character wheel, with its for the infrared counting group in infrared transmitting tube and the logarithm of infrared receiving tube identical.Namely when the quantity of the light tank of offering on each character wheel is 1, with its for the infrared counting group in infrared transmitting tube and infrared receiving tube respectively be 1; When the quantity of the light tank of offering on each character wheel is 2, with its for the infrared counting group in infrared transmitting tube and infrared receiving tube respectively be 2; When the quantity of the light tank of offering on each character wheel is n, with its for the infrared counting group in infrared transmitting tube and infrared receiving tube respectively be n.In the utility model preferred embodiment, the light tank on each character wheel is 7, and these light tanks are equally distributed on the same circumference along the axle center of character wheel.Infrared receiving tube and infrared transmitting tube on this moment every pair of infrared counting group also are 7, and wherein 7 infrared transmitting tubes are installed on the same block of radiating circuit plate, are in the wherein side for character wheel; 7 infrared receiving tubes are installed on the same circuit board for receiving, are in the opposite side for character wheel.Above-mentioned 7 pairs of infrared receiving/transmission pipe centerings, 3 pairs of infrared receiving/transmission pipes are to being the coding correction bit, other 4 pairs of infrared receiving/transmission pipes are to being the coding meter digital.On circuit connected, the infrared transmitting tube of every pair of infrared counting group (when light tank when being a plurality of, being the radiating circuit plate) and infrared receiving tube (when light tank when being a plurality of, being circuit board for receiving) all linked to each other with the counting end of microprocessing unit via counting drive plate.
When gas meter, flow meter was passed through in combustion gas, magnet can be along with the rotation of counting code-disc.When magnet when the tongue tube because magnetic induction line is got back to the S utmost point from the N utmost point, the tongue tube two ends are magnetized, form the corresponding S utmost point and the N utmost point.Like this, also just formed heteropole at the contact position of tongue tube, synonyms pole attracts each other, and makes the contact adhesive of tongue tube.When magnet during gradually away from tongue tube, reed switch contact will flick.Counting code-disc revolution 1 circle, magnet be just through tongue tube 1 time, produces 1 trigger pulse at the signal end of tongue tube and send in the microprocessing unit, triggers microprocessing unit control photo-electronic directly reading module the base table data are read.The data read mode of photo-electronic directly reading module is identical substantially with prior art.Namely
The photo-electronic directly reading module has adopted 7 pairs of infrared receiving/transmission pipes right during at the data read of each character wheel, i.e. Q1, Q2, Q3, Q4, Q5, Q6, Q7; They represent 6 bits of coded respectively, i.e. D0, D1, D2, D3, D4, D5, D6; The right signal output part of these 7 pairs of infrared receiving/transmission pipes respectively corresponding and with the PA0 of microprocessing unit, PA1, PA2, PA3, PA4, PA5, PA6, the PA7 data bit links to each other.When tongue tube sends trigger pulse when needs are read the data of this character wheel, the PC1 pin PC1 of microprocessing unit sends the control signal drive circuit board, make all 7 pairs of infrared tubes of every group of infrared counting group power on (voltage is VCC), be that infrared transmitting tube is luminous, infrared receiving tube begins to receive the infrared emission signal, and drive circuit board is delivered to microprocessing unit with the signal of each character wheel and handled.Microprocessing unit is set printing opacity and is represented 0 when carrying out the data processing, does not represent 1 thoroughly.
In order the metering signal of gas meter, flow meter to be back to the gas monitor and control center, also be connected to the wireless remote transmission communication unit on the described microprocessing unit.In the utility model, described wireless remote transmission communication unit can be GPRS communication module, 2G communication module, 3G communication module, 4G communication module and/or radio-frequency module.
