Description

Technical Field

[0001] The utility model relates to the technical field of anti-theft lead seals, in particular to an anti-disassembly electronic alarm lead seal for an industrial gas meter. Background Art

[0002] At present, one of the common methods of stealing gas by industrial and commercial gas users is to privately tamper with the gas meter parameters and destroy the meter counting structure. This method requires manual opening of the gas meter and destroying the original lead seal. The traditional lead seal adopts a metal sealing form, which has poor anti-theft performance. Management personnel need to regularly inspect the lead seal status to discover the theft of gas. At the same time, the traditional metal lead seal has no anti-copying function. The stealing gas molecules can copy and forge the metal lead seal to avoid being discovered by the inspectors. Another RFID lead seal upgraded on the basis of the traditional lead seal has an anti-copying function compared to the traditional lead seal. It can prevent the stealing gas molecules from copying the lead seal to a certain extent, but it also requires the inspectors to use special tools to detect the lead seal during daily inspections to discover the theft of gas, and it cannot locate the specific date of the theft of gas. Therefore, there is a need for a new type of electronic lead seal that can effectively prevent the stealing gas molecules from copying the lead seal information, record the date of the meter removal and theft, and actively report to the management personnel after the theft of gas occurs, without the need for the inspectors to conduct offline inspections. Summary of the invention

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-4 The utility model provides a technical solution: an anti-tampering electronic alarm lead seal for an industrial gas meter, comprising a shell 1, a first rectangular through hole is opened on the shell 1, a first card slot is provided on the shell 1, a sealing wire recovery wheel 2 is provided in the first card slot, a circular through hole is opened on the upper end of the shell 1, a convex frame 3 extending through the circular through hole is provided on the sealing wire recovery wheel 2, a sealing wire 4 is bolted in the shell 1, one end of the sealing wire 4 extends out of the shell 1, a communication line is provided in the sealing wire 4, the sealing wire 4 is overlapped with the sealing wire recovery wheel 2, and a wire inlet matching the position of the sealing wire recovery wheel 2 is opened on the shell 1.

[0015] As a preferred technical solution, further, a mainboard 5, a Bluetooth module 6 and a battery 7 are provided in the housing 1, and the mainboard 5 is connected to the Bluetooth module 6 and the battery 7 respectively.

[0016] As a preferred technical solution, further, the shell 1 is made of ABS engineering plastic.

[0017] It should be noted that:

[0018] This device is equipped with a host externally;

[0019] The box itself has an anti-tampering alarm, and the alarm contents are: cover opening alarm, low battery alarm, and on-site maintenance and inspection code scanning report; the communication host itself reports the status of the host and the supporting lead seal to the alarm data management background twice a day, and the service life of the host's built-in 20,000 mAh battery is ≥ 2 years; 4G transmission; the antenna can be extended; Bluetooth transmission information encryption is used between the host and the slave.

[0020] Bluetooth encrypted communication is adopted between the Bluetooth module 6 and the host.

[0021] It adopts many-to-one communication mode, one host corresponds to multiple slaves, and the slaves do not communicate with each other.

[0022] Internal form of electronic alarm seal: contains battery, main board, seal wire (communication wire).

[0023] The shell 1 is made of ABS engineering plastic. The diameter of the ultra-thin 4-core cable is 0.08mm.

[0024] There are 4 internal communication lines and ultra-fine signal lines. The signal lines correspond to 4 communication endpoints A / B / C / D on the mainboard. Two points are randomly generated inside as 485 communication signal lines, and the other two are receiving lines. 4 new ultra-fine wires are at the inner end of the lead seal, and the 4 cores correspond to the 4 communication endpoints. The tails of the wires extending to the outside are closed in pairs to form 2 loops.

[0025] When external damage occurs, the external sealing line of the Bluetooth seal is damaged, and the internal communication line is interrupted. The seal records the disconnection at this time and alarms the host at the same time. The alarm content is that the seal line is removed. After the alarm host receives the alarm signal, it is encrypted and transmitted to the anti-theft cloud platform

[0026] It should be noted that:

[0027] When the Bluetooth seal is damaged by someone and short-circuited, power is cut off or lost, the feedback signal is transmitted via Bluetooth to the communication control host for analysis and processing, and then the alarm signal is uploaded to the gas inspection alarm platform via the 4G / 5G network.

[0028] Disconnection Figure 4 As shown in the figure, when the signal line is interrupted, the alarm signal of the Bluetooth alarm mainboard is activated, and the alarm information is reported to the anti-theft alarm host, and the host reports to the backend

[0029] Power failure alarm: when the internal battery of the Bluetooth seal slave is powered off, the alarm host fails to communicate with the slave 4 times within 24 hours, and it will report that the Bluetooth seal is lost or powered off. The alarm background will prompt the administrator to inspect and verify.

[0030] The Bluetooth alarm seal is lost, the situation is the same as the power off alarm.

[0031] Inner Workings:

[0032] The alarm host and the Bluetooth seal use the 2.4G near-field communication frequency band for communication, and the communication content is encrypted. When the communication link is stable, the devices work normally, and the host and slave answer calls at a certain time interval.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".
