Detailed Description
The invention is further described with reference to the following figures and examples.
FIG. 1 is a view of the structure of an anti-tamper monitoring seal in an embodiment of the present invention; fig. 2 is a block diagram of a circuit for detecting the state of the wire lock lever according to an embodiment of the present invention.
Please refer to fig. 1 and fig. 2, the utility model discloses an anti-disassembly monitoring seal, including joint sealing lock body 1, joint sealing lock core 2 and steel wire locking lever 3, 2 cards of joint sealing lock core are established in joint sealing lock body 1, steel wire locking lever 3 passes joint sealing lock body 1 and is connected with joint sealing lock core 2, be equipped with the MCU control panel in the joint sealing lock body 1, prevent tearing open inductor and power supply battery, prevent tearing open the inductor and include first magnetic ring and second magnetic ring, first magnetic ring is passed to steel wire locking lever 3's one end, and the other end passes the second magnetic ring to seal by the steel wire in the joint sealing lock core and connect and form closed circuit, the output of MCU control panel and the both ends of first magnetic ring link to each other and carry alternating current signal to produce magnetic field, the induced electromotive force signal that the both ends of second magnetic ring and the input of MCU control panel linked to carry and monitor. The side of the box sealing lock body 1 is provided with an external interface 5, the box sealing lock body 1 is externally provided with an upper cover and a bottom cover, and a sealing ring 4 is arranged at the joint of the upper cover and the bottom cover.
The utility model discloses prevent tearing open monitoring strip of paper used for sealing, MCU control panel and signal reception antenna link to each other, signal reception antenna includes GPS antenna and GPRS antenna, the MCU control panel passes through GPS antenna receiving position signal, the MCU control panel passes through GPRS antenna receiving control signal and sends monitoring information and alarm signal. The GPS antenna acquires the position information in real time, the GPRS antenna transmits the monitoring information in real time, and the transportation process is completely transparent.
The utility model discloses prevent tearing open monitoring strip of paper used for sealing, through preventing in the joint sealing lock body that the difference of tearing open the received signal of inductor judges the state of steel wire locking lever 3. The disassembly-preventing inductor comprises a first magnetic ring and a second magnetic ring, two ends of the steel wire lock rod 3 penetrate through the first magnetic ring and the second magnetic ring respectively and then are clamped in the box sealing lock cylinder 2, two ends of the second magnetic ring are connected with the input end of the analog-to-digital converter through a detection circuit, the detection circuit is composed of a diode D1 and a capacitor C1, and the output end of the analog-to-digital converter is connected with the MCU control board.
With continued reference to fig. 2, L1 and L3 are inductances of the first magnetic ring and the second magnetic ring, respectively, L2 is an inductance of a closed loop formed by the steel wire lock rod 3 and the steel wire seal in the lock cylinder 2, and L1, L2 and L3 form an electromagnetic energy transfer chain. The diode D1 and the capacitor C1 form a detection circuit; the ADC is an analog-to-digital converter and measures voltage; the MCU control board is an embedded processor, reads out the voltage measured by the ADC and carries out judgment processing.
When the wire lock lever 7 is closed: the MCU control board transmits an alternating current signal into the L1, a magnetic field is generated in the L1 magnetic ring, induction current is generated on the closed L2 penetrating through the L1 magnetic ring, and when the current penetrates through the L3 magnetic ring, induced electromotive force is generated at the L3. The electrical energy is stored at C1 via a detector circuit consisting of D1/C1.
When the wire locking lever 3 is sheared or not locked: an alternating current signal is transmitted into the L1, a magnetic field is generated in the L1 magnetic ring, but an induced current cannot be generated because the steel wire lock rod 3 is opened. There is also no induced current at L3. In the subsequent D1/C1 circuit, the C1 has no power.
When the wire lock rod 3 is switched from the closed state to the shearing state: the electrical energy in C1 will self-discharge.
