Description
Technical field
Supervisory systems is used the present invention relates to a kind of, and in particular to a kind of supervisory systems for electrical metering device.
Background technique
Electronic scale is the measurement instrument for belonging to state key management.Currently, the common cheating mode of electronic scale have it is following several
Kind: one, the zero point of scale is debugged at negative value, as long as this cheating mode consumer slightly pay attention to can find；Two, using remote control
Cheating, i.e. change electronic scale internal wiring, private connects remote-receiver, using being mounted on electronic scale shelter or hand-held signal is sent out
Device is sent to control weighing and price and show, this cheating gimmick destroys the hardware configuration of scale, and there are sharp traces, is easy quilt
Examination of law enforcement mechanism investigates and prosecutes；Three, it is practised fraud using software code, this is the major way of present electronic scale cheating, this mode benefit
Electronic scale controls the reserved cheat code of software or switch so that electronic scale enters cheating state, sets for example, pressing different keys
Fixed different cheating gear, by can once increase weight 5%, by weight gain 10% etc. twice, pass through One-key recovery, power-off restarting after cheating
Restore, state of normally weighing can be restored in short two or three seconds.Therefore, user, always can be light when coping with examination of law enforcement
Pine escapes.For law enfrocement official, the electronic scale of this software code cheating is most ticklish.
And the technological means for preventing electronic scale from practising fraud at present mainly has: one, the 36V Low-voltage Electronic scale customized using unification,
220V electronics cheating scale current at present is kept outside of the door；Two, fixed point maintenance, by calling for bid, specified maintenance producer undertakes maintenance industry
Business prevents stall owner from changing electronic scale chip；Three, stick on antifalsification label on scale, special lead sealing approved sample, chip are carried out to electronic scale
Stick on special anti-counterfeiting mark；Four, " 12365 " identification code is set in electronic scale chip, convenient for identifying electronic scale when examination of law enforcement
Software source；Five, standard scale is set；Six, right-safeguarding counterweight is provided.These means constrain individual illegal stall owners from hardware and use
Cheated electronic weighing scale carries out the generation of metering fraud, improves WeiZhao's Notes, ensure that market electronic scale safety.But it is anti-
Cheat method or at high cost or limitation are big, can not fundamentally solve the problems, such as above-mentioned the third cheating mode cheating.
Therefore, there is an urgent need to a kind of anti-cheating supervisory systems that can solve the third cheat method.
