Description

Radio-frequency card remote-controlled intelligent water meter

The utility model belongs to the apparatus for metering fluids technical field, is specifically related to a kind of contactless memory long-distance remote control and uses a kind of radio-frequency card remote-controlled intelligent water meter that carries out exchanges data and automatic control switch

The rotor water gauge that tradition is used needs during charge to be checked meter to the doorstep from door to door by the personnel of tabling look-up, since unmanned among a variety of causes man of inhabitation family, be a great problem of common existence in the present water supply industry; The pattern of paying dues after this first water in the process of sharing of tap water consume, is easy to occur disputing over trifles, and causes being in arrears with the situation of water rate, and is more difficult.Along with development of electronic technology, the using method of this water meter is scientific and technical personnel through beginning to have invented IC-card formula intellectual water meter the sixth of the twelve Earthly Branches: the user holds to pay dues and buys water, will block and insert in the water meter, can realize the automatic gauge automatic switch, has saved the time of checking meter.But at present several intellectual water meters that use have the following disadvantages, and cause promoting slowly: (1) IC-card intellectual water meter, bad mechanical strength can not solve protection against the tide, the waterproof problem of access hole.(2) TM card intelligence table exists card easy to wear, and the solenoid valve reliability is low.(3) infrared ray, intellectual water meter exists security low, interference resistance is poor, be subject to extraneous light and various light wave and disturb, face produces the short 20mm of misoperation command range, and remote controller need be used power supply, water meter is in the low power capabilities that the power consumption state can not guarantee water meter for a long time, battery life is reduced greatly,, just can only shorten communication distance if improve serviceable life.The gate valve that the various intellectual water meters of (4) putting on market now use has two big classes basically, a kind of is the motor valve: the motor valve is to use micromotor, drive gate valve through gear reduction and carry out the switch task, the required driving of this valve is big, the power consumption height, cause the intelligence table short serviceable life, and can only be suitable for small-bore intellectual water meter, can't satisfy bigbore intellectual water meter.Another kind is a solenoid valve; Solenoid valve is to use the magnet control pilot valve with small flow controlling large flow, but because the pilot valve of solenoid control, be easy to be subjected to external interference, unfailing performance is low, and freedom from vibration is low, because electromagnetic force is limited, the pilot valve damping hole can only be opened very for a short time, and the sediment in the water just stops up the gate valve damping hole at short notice, causes solenoid valve to lose efficacy, can not work, limit promoting the use of of intellectual water meter thus.

The purpose of this utility model is to have above-mentioned deficiency at prior art, provides a kind of employing radio-frequency card to transmit carrier as message exchange, and reading writing information safe reliability height, pilot valve adopt micromachine to drive ball valve or ceramic valve is a pilot valve; Just damping hole can be increased, effectively overcome sedimentary obstruction in the water, avoid the solenoid valve anti-vibration resistance completely, the shortcoming of interference resistance difference, compact conformation, metering is a practical and reliable intellectual water meter of new generation accurately.

The utility model is to implement like this, radio-frequency card remote-controlled intelligent water meter, mainly include housing (16), battery case (9) and mechanical water meter etc., it is characterized in that the main message recipient (11) that wantonly is provided with, telepilot (14), LCD (7) and electronic guide's diaphragm valve (2), it is assembled into telepilot, it is that control core circuit board (10) connects respectively that single-chip microcomputer is housed in the housing (16), LCD (7), message recipient (11), battery case (9), and closed assembly is in pressurized capsule, and seal with insulating gel, connect electronic guide's diaphragm valve (2) downwards respectively, mechanical water meter (17), data transducer (15), its water inlet end (19) connects the water supply line upstream, and its water side connects the water supply line downstream; After finishing, the assembling of monoblock table is installed in low plate (18) housing (16).

The utility model can also be implemented like this, and electronic guide's diaphragm valve (2) includes barrier film valve block (4), spring (5), ball valve or ceramic valve (3) and micromotor (6); Ball valve or ceramic valve spool directly are contained in the damping hole of diaphragm valve (2), and horizontal or perpendicular putting installs micromotor (6) in the upper end of diaphragm valve, connect ball valve or ceramic valve spool (3).With single chip machine controlling circuit plate (10) is core, connects liquid crystal display circuit respectively, Card read/write circuit, low-voltage identification circuit, electronic guide's diaphragm valve circuit, water yield data variation sensor circuit, information processing memory circuit.

Radio-frequency card remote-controlled intelligent water meter described in the utility model is a contactless memory radio-frequency card remote-controlled intelligent water meter, comprise: the metering mechanism in shell, radio-frequency card, the shell, integrated circuit information processor, electronic guide's diaphragm valve, and the turnover water channel is formed by combining, its collection control machinery and metering mechanism are one, are provided with in the table: radio frequency receiver, the electronic guide's diaphragm valve of micropower; With the single-chip microcomputer is control core circuit board and battery case; Sensor is housed in the water meter counter; The output of control circuit board connects motor guide diaphragm control valve; Power input connects the positive and negative electrode of battery case; Water yield friendshipization information processing end connects the sensor of rotor water meter counter.

Little power consumption motor guide diaphragm valve inlet channel connects the water delivering orifice of rotor water meter, and the water outlet of the electronic guide's diaphragm valve of little power consumption connects water delivering orifice.The electronic guide's diaphragm valve of little power consumption comprises valve body, turnover water channel, spool (ball core or ceramic core) sealing gasket, spring, guide finger and micromotor.Driven by micromotor, micro ball valve is controlled guide's flow liquid body by motor-driven micro ball valve or ceramic valve, when minimizing diaphragm valve back pressure face Inlet and outlet water pressure at two ends equates, under spring action, the rising of diaphragm valve and decline, thus finish the task of opening or closing valve.

The utility model has the advantages that:

(1) this table adopts radio-frequency card as water yield information carrier, and radio-frequency card has the excellent safety energy, security performance, and humidity resistance, interference free performance does not need power supply, is that the intellectual water meter of other several cassettes is beyond one's reach.

(2) adopt the electronic guide's diaphragm valve of little power consumption: it has all advantages of solenoid valve and motor valve, and dependable performance, interference resistance is strong, more can practically develop bigbore water meter, power consumption is little, and does not have leakage, compact conformation meets the standard installation dimension of existing mechanical water meter.

(3) adopt the radio-frequency card remote controller to make information transmission, remote control is apart from far away, and interference resistance is strong, safety and reliability, and except that can be for the operation of single table remote control system, remote monitor more, modern management levels such as team control provide effective support.
