Description
Technical field
The utility model belongs to intelligent gas meter technical field, especially a kind of based on Hall element and small-sized magnet steel
Intelligent anti-theft gas meter.
Background technology
When usual intelligent gas meter uses internal battery, all can install Anti-theft-dismounting device additional at electronic control unit, work as user
Table tool will be caused when privately changeing battery normally not use.At present, domestic gas meter, flow meter uses the mode of machinery seal mostly
Prevent from user from stealing to tear open, although this device is prevented from the private of a part of user and tears behavior open, but machinery seal is stolen tear open after,
Gas meter self can not make any reaction, still can normally use.It is difficult to discovery as administrative department, it is impossible to have
Effect supervision.
Content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of reasonable in design, stable performance and peace
Complete reliably based on the Intelligent anti-theft gas meter of Hall element and small-sized magnet steel.
The utility model solves it and technical problem is that and take techniques below scheme to realize:
A kind of Intelligent anti-theft gas meter based on Hall element and small-sized magnet steel, including upper casing, lower casing and interior
The gas meter, flow meter control circuit in portion, described upper casing and lower casing are installed together, at upper casing with lower casing relative to position difference
Being provided with small-sized magnet steel and Hall element, small-sized magnet steel and Hall element composition anti-theft monitoring and control module are simultaneously connected to
In gas meter, flow meter control circuit.
Described gas meter, flow meter control circuit include single-chip microcomputer and peripheral circuit, power supply, post circuit, RS232 communication interface,
IrDA communication interface, IC-card read-write interface, EEPROM, alarm circuit, anti-theft monitoring and control module；Described power supply uses
Lithium battery is that modules is powered, described post circuit, RS232 communication interface, IrDA communication interface, IC-card read-write interface,
EEPROM, alarm circuit are connected with single-chip microcomputer and peripheral circuit, this single-chip microcomputer and peripheral circuit also with anti-theft monitoring and
Control module is connected, and this anti-theft monitoring and control module are connected with valve.
Advantage of the present utility model and good effect be:
The utility model is mounted opposite low-power consumption Hall element and small-sized magnet steel in gas meter, flow meter upper casing and lower casing
And under the control of corresponding gas meter, flow meter control circuit, it is achieved Anti-theft-dismounting function, once find robber tear open, gas meter can first when
Between make a response, close valve on table, forcing robber to disassemble and use family must the circular management department acceptance of punishment being used by administrative department
Dedicated management card carries out restorative valve opening, thus realizes the requirement of intelligent gas meter Anti-theft-dismounting, and it is stable and reliable for performance.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is circuit diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
A kind of Intelligent anti-theft gas meter based on Hall element and small-sized magnet steel, including the gas meter, flow meter of casing and inside thereof
Control circuit.As it is shown in figure 1, described casing is installed together by upper casing 1 and lower casing 4, relative with lower casing at upper casing
Position is separately installed with small-sized magnet steel 2 and Hall element 3, small-sized magnet steel and Hall element composition anti-theft monitoring and control mould
Block is simultaneously connected in gas meter, flow meter control circuit.Owing to Hall element is a kind of COMS nonpolarity highly sensitive low-power consumption unit
Part, therefore, it is very little on battery power consumption impact.
As in figure 2 it is shown, gas meter, flow meter control circuit includes single-chip microcomputer and peripheral circuit, power supply, post circuit, RS232 communication
Interface, IrDA communication interface, IC-card read-write interface, EEPROM, alarm circuit, anti-theft monitoring and control module.Described electricity
It is that modules is powered that source uses lithium battery, and described post circuit, RS232 communication interface, IrDA communication interface, IC-card read-write connect
Mouth, EEPROM, alarm circuit are connected with single-chip microcomputer and peripheral circuit and realize gas meter, flow meter basic control function, this single-chip microcomputer
And peripheral circuit also forms anti-theft monitoring with by small-sized magnet steel and Hall element and control module is connected, this anti-theft monitoring and
Control module is connected with valve, by small-sized magnet steel and Hall element, single-chip microcomputer monitors whether upper and lower enclosure separates (robber
Tear open), when single-chip microcomputer detects that robber tears situation generation open, closed valve by anti-theft monitoring and control module and send warning, combustion
Gas meter can not normally use.After administrative department uses dedicated management card to safeguard, single-chip microcomputer opens valve by control module, extensive
Resume combustion gas meter normally uses.
Operation principle of the present utility model: small-sized magnet steel and Hall element are separately mounted to relative position in casing,
Small-sized magnet steel forms magnetic sensor with Hall element.In normal use, small-sized magnet steel acts on Hall element, makes Hall
Sensor remains under channel status.If housing is illegally taken apart, small-sized magnet steel is away from Hall element so that it is be in
Off state, is detected by single-chip microcomputer, it is possible to determine that steals and tears open.Therefore, open circuit once detected, single-chip microcomputer pass through anti-theft monitoring and
Control module starts close valve state immediately, even if user restores to the original state again, table tool is still within closed mode, it is impossible to continue normal
Use.User can only circular management department, restore with special management card.
It is emphasized that embodiment described in the utility model is illustrative, rather than determinate, therefore this reality
Include being not limited to the embodiment described in detailed description of the invention with novel, every new according to this practicality by those skilled in the art
Other embodiments that the technical scheme of type draws, also belong to the scope of the utility model protection.
