Accompanying drawing explanation
Fig. 1 is circuit block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described.
An anti-theft device based on IC-card prepayment diaphragm gas meter, as shown in Figure 1, comprises the burglar-proof mechanism being arranged on gas meter, flow meter casing and is arranged on the theft-proofing control circuit in gas meter, flow meter casing.Electro-conductive glass in the character wheel display window that described burglar-proof mechanism comprises the anti-theft wire being arranged on gas combustion meter pipe web member, the electronic anti-theft label that is arranged on casing sealing part and is mounted on gas meter, flow meter, described theft-proofing control circuit comprises single-chip microcomputer and peripheral circuit, power management module, casing tamper testing circuit, wire testing circuit, electro-conductive glass testing circuit, magnetic interference testing circuit, valve driving circuit, IC-card module for reading and writing and alarm module.Power management module is connected with modules for its power supply, single-chip microcomputer and peripheral circuit are connected with tamper testing circuit, wire testing circuit, electro-conductive glass testing circuit, and described casing tamper testing circuit, wire testing circuit and electro-conductive glass testing circuit is connected with electronic anti-theft label, anti-theft wire and electro-conductive glass respectively and under the control of single-chip microcomputer, realizes antitheft measuring ability; Described single-chip microcomputer and peripheral circuit are connected and realize magnetic disturbance detection function with magnetic interference testing circuit, single-chip microcomputer and peripheral circuit are connected with valve driving circuit and alarm module, when antitheft situation being detected, pass through valve driving circuit valve-off, or carrying out sound and light alarm by alarm module, single-chip microcomputer and peripheral circuit are connected and realize IC-card read-write capability with IC-card module for reading and writing.
Anti-theft wire is arranged on gas combustion meter pipe web member, mainly prevents that user from privately dismantling and reequiping.User tears table open must first pull down anti-theft wire, after anti-theft wire is removed, theft-proofing control circuit automatically detects anti-theft wire by wire testing circuit and disconnects, by valve driving circuit, controlling gas meter valve closes, and user connects after anti-theft wire again can not Open valve, function card that must be by gas company can Open valve, can prevent that like this user from stealing gas and can prevent that again user from tearing table privately open.
Electronic anti-theft label is arranged on the sealing part of casing, this electronic tag is globally unique and this tag number has been inputted computing machine, this label is disposable, once open, will damage, and it is not reproducible, even internal staff goes privately to change like this, also there are data to be recorded in write by hand device, accomplish to have good grounds.Safety check is simultaneously registered one's residence and is read this label as the authority of registering one's residence while tabling look-up.Theft-proofing control circuit is opened by casing tamper testing circuit automatic detecting machine shell, controls gas meter valve close by valve driving circuit.
