Road.The temperature data that temperature sensor is detected is sent to control unit, when temperature is more than setting value, by control unit
Into external control cabinet, micro computer transmits control signal, it is made to cut off the power supply of the driving coil of charge gun.Temperature sensing
Although device is not in driving coil device 1, since the heat-conducting glue being connected as a single entity can conduct heat, slightly lower temperature control is being set
Can equally be realized under target conditions prevents the purpose of thermo-field thoery.Meanwhile the heat-conducting glue being connected as a single entity is by driving coil and institute
There are circuit board, cable to be wrapped in inside, the electronic component inside charge gun can thoroughly be avoided to cause liquid when generating electric spark
Change gas station and fire or explosion occurs.Accordingly, with respect to the prior art, the utility model can realize temperature duplicate protection, reach
The explosive-proof protector grade of glue envelope " ma ".
The operation principle of the utility model：
Intelligence (is arranged on by the radio wave energy electron label of the card reading unit transmitting specific frequency of inflation gun apparatus
RFID chip on angle valve), to drive electronic tag circuit by Inner portions number and data send out, card reading unit receives this volume
Number and data.The special of electronic tag is battery-free, contact-free, exempts to swipe the card therefore not be afraid of the dirty, long-life, and chip password
It can not uniquely be replicated for the world, safe anti-counterfeiting technology is strong；Control unit uses 32 bit processors of ARM, can reach
72MHz working frequencies.In addition to master data analytic operation function, some defencive functions can also be included, for example, it is over-pressed, deficient
Pressure, overcurrent, overtemperature etc., it can be achieved that defencive function realization method see Fig. 5.Communication unit uses two-wire system RS485 communication modes,
It is responsible for the communication of control panel and micro computer in control cabinet, RS485 communication modes strong antijamming capabilities, transmission is stablized.This practicality is new
In type, communication and power cable are connected (including communication and 5V, 36V power supply) by using a cable bellows with control cabinet,
Specifically optional high-low temperature resistant flexible cable.
(refer to that the angle valve on steel cylinder is mounted with RFID chip and can be triggered by driving coil device 1 equipped with intelligent angle valve
Realize open and close overfill-limiting device) new liquefied gas bottle be sent to liquefied gas station after, pass through the gas station by liquefied gas gas-filling station personnel
Permission identity carries out gas cylinder data input, including gas cylinder number, date of manufacture, gas cylinder property information, gas cylinder user identity letter
Breath etc., therefore the charge gun at gas station can only fill the liquefied gas bottle registered in systems.
The utility model for ease of understanding, the intelligent angle being used cooperatively with reference to one with charge gun in the utility model
The topology example of valve is illustrated：Intelligent angle valve includes drive component and limit fills component；Drive component includes a root long bar shaped
Iron core, outside sheathed spring；The outer end of iron core is equipped with several groups of permeability magnetic material beckets；Limit, which fills component, includes phase interworking
The spool and valve core case of conjunction, sheathed spring on the outside of spool, valve core case are located in the gas passage of steel cylinder interface；Spool is equipped with recessed
Sunken slot can drive spool displacement when iron core end is inserted into slot, and the passage and the blow vent for making steel cylinder interface connect
It is logical.Overfill-limiting device closes the passage of steel cylinder interface for being engaged under non-released state by spool with valve core case.When to steel cylinder
In need to use the charge gun with driving coil device 1 when filling liquefied gas, the driving coil device 1 for being passed through alternating current is close
The drive component of valve.The becket of drive component is made of special low-density permeability magnetic material, is generated in driving coil device 1
Variation magnetic field effect under, becket can generate a magnetic force opposite with its magnetic direction, thus with dynamic iron core
Against the force of the spring generates transverse movement, makes in the groove on iron core end insertion spool, and spool is lifted up.It is inflating
In the process, since the position-limiting action of iron core makes the spool of overfill-limiting device remain opening state.When lpg filling is completed,
Charge gun is removed, away from drive component, spool is returned in situ and matched somebody with somebody with valve core case driving coil device 1 under the action of the spring
Close the passage of closing steel cylinder interface.Iron core end of drive component is extruded during this, and is returned under the action of the spring initial
Position.
When the intelligent angle valve that charge gun is docked on cylinder for liquefied gas, which carries out card rifle, to be filled, the rifle mouth of charge gun
12 are docked to the inflatable interface of intelligent angle valve.At this point, control unit driving card reading unit reads the RFID on intelligent angle valve
Chip information.For RFID chip there are four encrypted storage sector, solution is identified to each memory block respectively in charge gun control panel
After close, gas cylinder data (such as gas cylinder number, date of manufacture, gas cylinder property information) are read.Control unit carries out steel cylinder information
Primary data analysis, and pass through communication unit and data are issued to micro computer in control cabinet.Micro computer stores institute of liquefied gas station
Some gas cylinder data, by mainly generating following two results after data comparison and processing：
(1) system confirms that gas cylinder data are normal and meet burner structure --- it is single that micro computer will inflate signal transmission control
Member, progress corresponding state indicating concurrent send inflation signal to give control cabinet 36V electric power driving modules after control unit receives signal；
Output pulse ac supplies electricity to driving coil device 1 after 36V electric power driving modules receive signal, and driving coil device 1 receives power supply
Strength variation magnetic field is generated afterwards, and changing magnetic field power makes the overfill-limiting device in intelligent angle valve generate magnetic force and realizes in filling process
Overfill-limiting device is in opening state, and liquefied gas can be filled with gas cylinder.
(2) system confirms gas cylinder data exception or is unsatisfactory for that burner structure --- such as gas cylinder annual test date transfinites or gas
Bottle information owns for non-our station, and gas cylinder abnormal signal is issued control unit by micro computer, and control unit is received after signal by aobvious
The abnormal state of air cylinders alarm of showing device (such as indicator light or alarm buzzer) display, 36V electric power driving modules, which can not receive, at this time wants
Seek the signal of power supply, the overfill-limiting device in intelligent angle valve is being closed, and liquefied gas can not be filled with gas cylinder at this time.
Micro computer in control cabinet forms inflation record and sends data to cloud server end, and Cloud Server stores each liquid
Change the gas cylinder information at gas station and inflation record data, Cloud Server and its platform software can be by internets to each liquefied gas
Data of standing carry out unified storage, management, and relevant enterprise, correlation superintendent office of government can be carried out by corresponding platform software interface
Data access.
Therefore, the actual range of the utility model not only include the disclosed embodiments, be additionally included in claims it
Under be practiced or carried out all equivalent schemes of the utility model.
