Abstract
The invention relates to a lead seal device, in particular to an electronic lead seal based on an electric power remote meter-reading system, which consists of signal input wires connected onto an electric energy meter, a complementary metal-oxide-semiconductor transistor (CMOS) integrated circuit board and a signal output wire. At least a pair of signal input wires A and B is led out of an electric energy meter circuit board, the rear ends of the signal input wires A and B are connected with the CMOS integrated circuit board, the CMOS integrated circuit board adopts alternative denial gate circuits including at least two signal connecting wires and a signal output wire, and the signal connecting wires are connected with the signal input wires through signal wire connectors. The signal output wire is connected with a memory chip in an acquisition system. By implementing the technical scheme, on-line monitoring can be performed to the lead seal, and when the lead seal is damaged, a user can find timely and accordingly take protective measures to minimize the loss.
Description
Technical field
The present invention relates to a kind of sealing device, relate in particular to a kind of based on the power remote meter reading system electronic lead sealing.
Background technology
The management of ammeter lead sealing is the key link of power marketing, is the important means that prevents that electric weight from being stolen.At present, China's electric energy meter lead sealing overwhelming majority is the mechanical type lead sealing, and the stealing molecule can cut off easily that the lead sealing line is laggard commits theft.Remedy electric weight and belong to " mending the fold after the sheep is lost " formula, just might come to light after causing very big economic loss.
Summary of the invention
The objective of the invention is to propose a kind of capable of automatic alarm, can't physical disturbance based on the power remote meter reading system electronic lead sealing.
The objective of the invention is to realize like this:, form by the signal input line, CMOS surface-mounted integrated circuit, the output line that are connected on the electric energy meter based on the power remote meter reading system electronic lead sealing.Draw at least one pair of signal input line A, B from electric energy meter circuit plate; After connect the CMOS surface-mounted integrated circuit; The CMOS surface-mounted integrated circuit adopts NAND gate circuit; It contains at least two signal connecting lines and an output line, and said signal connecting line is communicated with through signal wire joint with signal input line.Output line is connected with storage memory chip in the acquisition system.
Owing to implement technique scheme, can carry out real time on-line monitoring to lead sealing, when lead sealing is destroyed, can in time find, thereby take safeguard procedures, loss is dropped to minimum.
Description of drawings: concrete structure of the present invention is provided by following accompanying drawing and embodiment:
Fig. 1 is a smart electronics lead seal structure synoptic diagram;
Fig. 2 is a CMOS surface-mounted integrated circuit circuit diagram;
Fig. 3 is that the smart electronics lead sealing is installed in the structural representation on the electric energy meter;
Fig. 4 is power remote meter reading system smart electronics lead sealing overall workflow figure.
Legend: 1, electric energy meter circuit plate, 2, signal input line, 3, signal connecting line, 4, signal wire joint; 5, CMOS surface-mounted integrated circuit, 6, alarm lamp, 7, output line, 8, the storage memory chip; 9, infrared communication mouth, 10, the electric energy meter display screen, 11, gib screw.
Embodiment: the present invention does not receive the restriction of following embodiment, can confirm concrete embodiment according to technical scheme of the present invention and actual conditions.
Embodiment:, form by the signal input line (2), CMOS surface-mounted integrated circuit (5), the output line (7) that are connected on the electric energy meter based on the power remote meter reading system electronic lead sealing like Fig. 1, shown in 2.Draw at least one pair of signal input line A, B (2) from electric energy meter circuit plate (1); After connect CMOS surface-mounted integrated circuit (5); CMOS surface-mounted integrated circuit (5) adopts NAND gate circuit; It contains at least two signal connecting lines (3) and an output line (7), and said signal connecting line (3) is communicated with through signal wire joint (4) with signal input line (2).Output line (7) is connected with storage memory chip (8) in the acquisition system.Between output line (7) and storage memory chip (8), be in series with alarm lamp (6).Storage memory chip (8) can adopt host computer to substitute, and can directly on the software interface of acquisition system, increase by a sub-module, and it can store the disconnection of electronic lead sealing record.
Signal input line (2) is a copper cash, is surrounded by transparent insulation course outside it, disturbs simultaneously the switching situation that can conveniently check signal input line (2) at the shielding ambient signals.
Signal wire joint (4) adopts the crystal head technology of computer netting twine to make, and includes the compressing tablet of 2-4 parallel connections in it, and short circuit constitutes the conducting loop together between each compressing tablet.
As shown in Figure 3, signal wire joint (4) is fixed on the outer surface of electric energy metering box, and signal input line (2) is fixed on the gib screw (11), and gib screw (11) is in order to cover and casing secure bond with electric energy metering box.
When lawless people is opened electric energy metering box in violation of rules and regulations; Just must screw off two gib screws (11) earlier; At this moment the signal input line (2) that is connected on the gib screw (11) will be by extracting in the signal wire joint (4); This moment, signal input line (2) and signal connecting line (3) opened circuit, and alarm lamp (6) will light, and simultaneously the state that breaks off were stored in the storage memory chip (8).
As shown in Figure 4, utilize the data transmission channel of power remote meter reading system, the smart electronics lead sealing with data transmission of development; Be contained in that every electronic electric energy meter all has fixing physical address on the electric energy meter; With electric power copy system networking far away, the off-state of electronic lead sealing temporarily is stored in the watt-hour meter memory again; Wait to receive to check meter and be uploaded to supervisory computer with electric quantity data behind the signal; Monitoring electronic lead sealing state is in time reported to the police after lead sealing is broken off in real time, has constituted a networking lock system.Monitor watt-hour meter lead sealing opening in real time.
Above technical characterictic has constituted most preferred embodiment of the present invention, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
