Description

Technical Field

[0001] The utility model relates to the technical field of anti-theft electronic alarm lead seals, in particular to a resistance-type anti-theft electronic alarm lead seal. 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

[0014] 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.

[0015] See also Figure 1-5 The utility model provides a technical solution: a resistance-type anti-theft electronic alarm lead seal, comprising a shell 1, the shell 1 is provided with a Bluetooth module, the shell 1 is provided with an outlet, the lower wall surface of the shell 1 is bolted with a first sealing wire 3, the first sealing wire 3 is conductive plastic (graphite fiber) inside and insulating skin outside, the side wall of the shell 1 is provided with an inlet above the outlet, a partition 4 is installed in the shell 1 and between the inlet and the outlet, a first one-way buckle 5 is provided on the partition 4, an electrode scraper 6 is provided on the partition 4 and behind the first one-way buckle 5, and a locking button 2 is provided on the shell 1 and above the electrode scraper 6.

[0016] As a preferred technical solution, further, a battery and a main control circuit board are installed in the shell 1, the battery is directly connected to the main control circuit board through a battery holder, and the main control circuit board is fixed in the inner shell.

[0017] As a preferred technical solution, further, the locking button 2 is provided with a second one-way buckle.

[0018] This device is connected to a host:

[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 used between the Bluetooth slave 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 the Bluetooth slave: Contains battery, main board, sealing wire (sampling resistor wire), electrode scraper.

[0023] The shell 1 is made of ABS engineering plastic, and the inside of the sampling resistor wire is made of conductive plastic material. The resistivity is stable and does not change with the ambient temperature and humidity. The outer skin of the sealing wire 3 is wrapped with an insulating sheath. When in use, the electronic lead seal sealing wire 3 can be stored in the lead seal return groove. There is a locking buckle in the return groove. After pressing the buckle, the sealing wire 3 cuts into the electrode scraper notch, and the scraper cuts into the inside of the sealing wire 3, splitting the insulating outer skin to keep the electrode metal layer and the conductive area of ​​the sampling resistor wire in contact. After contact, the main board records the resistance value of the sampling resistor, and encrypts the resistance value signal and uploads it to the monitoring host. The host saves the data. When the lead seal finds that the previously saved resistance value is inconsistent with the recorded value, the alarm program is started when the error is greater than the threshold.

[0024] The screws between the sampling resistor and the circuit board are metal self-tapping screws, which can penetrate into the conductive graphite fiber layer inside the sampling resistor to ensure stable electrical contact.

[0025] There is a one-way buckle in the cable storage slot. When the cable tie is put into the storage slot, the one-way buckle locks the cable tie to prevent it from moving outward.

[0026] There is a one-way buckle on the start button. After being pressed tightly, it cannot move outward and will not pop open naturally unless it is broken into.

[0027] The above structure can quickly complete the on-site lead sealing operation, reduce the operation of the staff, and improve the operation efficiency.

[0028] When the Bluetooth seal is damaged by someone, causing a short circuit, power outage or loss of connection, 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.

[0029] 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 background.

[0030] 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.

[0031] The Bluetooth alarm seal is lost, the situation is the same as the power off alarm.

[0032] Inner Workings:

[0033] 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.

[0034] 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.
