Description

The IC-card gas meter, flow meter is stolen the gas recording control apparatus

The utility model relates to a kind of IC-card gas meter, flow meter, and particularly a kind of IC-card gas meter, flow meter is stolen the gas recording control apparatus.

Robber's gas mode of IC-card gas meter, flow meter mainly contains following several: first kind is that magnetic interference steals gas, and it utilizes the ferromagnetism magnetic patch to increase the resistance of magnetic gearing wheel near being placed on gas meter, flow meter, thereby reaches the purpose of stealing gas to reduce counting; Steal gas for unloading table door for second kind, it is that the table door of gas meter, flow meter is laid down, and the power wheel of dismantling is stolen gas; The third steals gas for unloading the table valve, and it is that the draft tube of gas meter, flow meter and direct connection of escape pipe are stolen gas; The 4th kind is to destroy with high-tension electricity to steal gas, and it is to utilize civilian 220 volts of alternating currents or accumulator that the circuit in the IC-card gas meter, flow meter is punctured, and it can not normally be counted steal gas; The 5th kind is slotting special-shaped card robber gas, utilizes non-special cards such as various cards such as iron plate, plastic sheet, phonecard, magnetic card disorderly slotting on deck exactly, to destroy the operate as normal of gas meter, flow meter.Anti-theft gaseous device at these several robber's gas methods also has other application on some IC-card gas meter, flow meters, but after taking place to steal the gas phenomenon, sometimes be difficult to find that what have both makes discovery, is difficult to impose a fine to stealing the gas user because of lacking to resemble to steal the gas time and steal the such evidence of gas type.

The purpose of this utility model will provide a kind of exactly and can steal the gas time and steal the gas type by accurate recording, and can in time close the IC-card gas meter, flow meter robber gas recording control apparatus of ACV Air Cut Valve.

The novel employing of this reality technical scheme as described below for achieving the above object: the IC-card gas meter, flow meter is stolen the gas recording control apparatus and is comprised singlechip CPU, IC-card deck, the I/O mouth of IC-card deck connects the p7.6 and the p7.7 end of single-chip microcomputer, the p5.5 of single-chip microcomputer and p5.6 end are respectively out valve and close the valve signal output terminal, and it also has a readable and writable memory and a calendar clock module; Two input ends of calendar clock module are connected on the p6.6 and the p6.7 end of single-chip microcomputer, and its two output terminal is connected to the input end of readable and writable memory, and the I/O mouth of readable and writable memory connects the p7.1 and the p7.2 end of single-chip microcomputer; Antimagnetic robber's gas signal, anti-unload the table gate signal, anti-ly unload the table valve signal and anti-high-tension electricity destroys p6.1, p6.3, p6.4 and the p6.5 end that signal is connected to single-chip microcomputer respectively.Steal gas, unload the table door and steal gas, unload the table valve and steal gas and high-tension electricity and destroy when stealing any phenomenon of gas when magnetic interference occurring, corresponding signal is sent to single-chip microcomputer, single-chip microcomputer is at first exported the pass valve signal, fuel gas pipeline is turn-offed, at the same time, on behalf of the code of stealing the gas type, single-chip microcomputer will send into readable and writable memory, and carry out passing single-chip microcomputer again back and having its RAM district behind the assembly coding with detailed robber's gas time that the calendar clock module is sent here; Anti-special-shaped card is stolen gas and is achieved in that as special-shaped card insertion IC-card deck, compare from the password that reads of card and with the password that pre-deposits in the RAM district in the single-chip microcomputer, if password is correct, be subscriber card, if password bad, be special-shaped card just, and will steal the gas type and steal the RAM district of gas time keeping at single-chip microcomputer through readable and writable memory.

Adopt the utility model of said structure to design ingenious uniqueness, reliable operation, can steal the gas time and steal the gas type by accurate recording, and can in time close ACV Air Cut Valve, steal the gas evidence for extraction method and approach easily are provided.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is circuit theory diagrams of the present utility model.

With reference to Fig. 1.The IC-card gas meter, flow meter is stolen the gas recording control apparatus and is comprised singlechip CPU and IC-card deck 1, the I/O mouth of IC-card deck connects the p7.6 and the p7.7 end of single-chip microcomputer, the p5.5 of single-chip microcomputer and p5.6 end are respectively out valve and close the valve signal output terminal, and it also has a readable and writable memory 2 and a calendar clock module 3; Two input ends of calendar clock module 3 are connected on the p6.6 and the p6.7 end of single-chip microcomputer, also be connected to respectively on two input ends key AN1 and AN2 are set, year, month, day, hour, min, second are set for the calendar clock module by this two button, two output terminals of calendar clock module are connected to the input end of readable and writable memory 3, and the I/O mouth of readable and writable memory 2 connects the p7.1 and the p7.2 end of single-chip microcomputer; Antimagnetic robber's gas signal, anti-unload the table gate signal, anti-ly unload the table valve signal and anti-high-tension electricity destroys signal is connected to single-chip microcomputer respectively through interface a, b, c, d p6.1, p6.3, p6.4 and p6.5 end.Prevent that magnetic interference robber gas is that the low level of utilizing a tongue tube to extract is useful signal, unloading and showing door robber gas all is that the low level of utilizing microswitch to extract is useful signal with unloading table valve robber gas, and high pressure destruction robber gas is that the high level that utilizes potentiometer to extract is useful signal.Steal gas, unload the table door and steal gas, unload the table valve and steal gas and high-tension electricity and destroy when stealing any phenomenon of gas when magnetic interference occurring, corresponding signal is sent to singlechip CPU, single-chip microcomputer at first closes valve signal from its p5.6 end output, fuel gas pipeline is turn-offed, at the same time, on behalf of the code of stealing the gas type, singlechip CPU will send into readable and writable memory 2, and carry out passing single-chip microcomputer again back and having its RAM district behind the assembly coding with detailed robber's gas time that calendar clock module 3 is sent here; Anti-special-shaped card is stolen gas and is achieved in that as special-shaped card insertion IC-card deck 1, the password that pre-deposits in the RAM district in the password that reads of card and the single-chip microcomputer is compared, if password is correct, be subscriber card, if password bad, be special-shaped card just, and will steal the gas type and steal the RAM district of gas time keeping at single-chip microcomputer through readable and writable memory.

Gas company is investigated and prosecuted when breaking rules and regulations, user's IC-card is inserted deck, this moment single-chip microcomputer RAM district in robber's gas information of writing down with regard to unloading on IC-card, this card is delivered to the host computer database of gas company, just can read the time of breaking rules and regulations and type of violation, and make historical record, after the event handling of robber's gas is intact, a processing signals is provided for user's IC-card, again this IC-card is inserted on the deck 1 of gas meter, flow meter by host computer, single-chip microcomputer reads processing signals, recovers air feed.
