Abstract
The invention uses conductive plastic with conductive stuff as electric seal line, wherein when the line is inserted into the main body of electric seal, it will be connected to the connector, spring, tooth bar, controller and battery of electric detector in the main body, to form integral circuit loop; when the line is cut off and drawn outside the electric seal, the former closed loop will be broken. Therefore, by detecting the circuit change of line, it can detect the state of electric seal.
Description
Affiliated technical field
The present invention is as the e-seals cord material with conductive plastic, when rope inserts the e-seals main body, rope is connected with joint, control element, the battery of electronic detecting device in the e-seals main body, form complete electric loop, different circuit states during by the connection of detection rope, disconnection change, unlatching, the closure state of identification e-seals, the legitimacy of judgement e-seals opening prevents to fake; Adopting PS, PC, ABS, PA, PBT, PPO, polysulfones, polyphenylene oxide, polyphenyl ether ether ketone, PPS, Nylon, PE, POM, PP and PC is the conductive plastic product of base material, as the e-seals cord material.
Background technology
At present, e-seals mostly adopts the on/off that detects strip of paper used for sealing in-to-in electricity loop (magnetic loop), judges the opening of e-seals.Rope inserts the strip of paper used for sealing main body, forms corresponding electric loop (magnetic loop), and after the loop was destroyed, the e-seals priming was reported to the police, and finishes detection thus; E-seals electricity return circuit detection method can utilize the method at the other wire jumper in two ends, loop to crack; The break-make method of inspection of magnetic loop can substitute by other magnetic conductors and crack, and causes the difficulty of supervision.
Summary of the invention
In order to improve existing product, solve the monitor closely problem in the security product use to e-seals anti-theft alarm sensitivity, real-time degree and the deficiency of monitoring.The invention provides a kind of being difficult to cracks, plastic electronic seal technology simple in structure, that cost is low, easy to use, adopt the method that detects conductive plastic rope resistance variations, sensitive identification rope is opened and any intentional destruction and cheating action that the e-seals rope is carried out, and can in time record in the e-seals data.
The technical solution adopted for the present invention to solve the technical problems is: adopt conductive plastic as the e-seals cord material, after rope inserts the e-seals main body, form complete electric loop by main body nipple, spring, tooth bar, control element, battery, whether whether e-seals can be by judging and writing down strip of paper used for sealing rope integraty and destroyed by the resistance variations, electric current, the electronic impulse that detect this electric loop; The backstage system is provided with e-seals by wireless signal to execute the envelope monitor state, and detect, write down the resistance of rope ends and increased resistance value in real time whether in the predetermined threshold value scope by control element, stored record stores to e-seals control element data, thereby judges the integraty of e-seals.
The invention has the beneficial effects as follows: utilization linear resistance method of inspection, can detect rope and open and any intentional destruction that the strip of paper used for sealing rope is carried out, whether whether utilization electric current, electronic impulse can be destroyed by judgement of strip of paper used for sealing rope and record strip of paper used for sealing rope integraty.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Working state figure when Fig. 1 prevents that for e-seals the open detection device is closed.
Working state figure when Fig. 2 opens for the anti-open detection device of e-seals.
(1) rope (outsourcing insulator) among Fig. 1, Fig. 2, (2) exposed conductive part, (3) spring, (4) tooth bar, (5) battery, (6) control element, (7) e-seals main body.
The specific embodiment 1
In the embodiment shown in fig. 1, in e-seals main body (7), spring (3), tooth bar (4) touch mutually with control element (5), when rope (1) during by outer importing e-seals main body (7) two ends, tooth bar (4) compression spring (3), rope (1) can import smoothly along the direction of tooth, exposed conductive part (2) up to rope (1) contacts with tooth bar (4), because the effect of spring (3) and the back-off structure of rope exposed conductive part (2), rope (1) is locked, can not directly extract.Rope this moment (1) forms electric loop with control element by tooth bar (4), the resistance that detects rope (1) two ends by the detecting device in the control element (6) is steady state, status information is stored in the storage data of control element (6), storage data can be read by background system, at this moment, the e-seals background system is provided with e-seals by wireless signal and enters and execute the envelope monitor state, and e-seals writes down the resistance value of current strip of paper used for sealing, and beginning detects resistance variations in real time.
In embodiment illustrated in fig. 2, e-seals is honored as a queen via the backstage proper solution, along A rope (1) is cut off, rope (1) remainder can be extracted out along the B direction, control element this moment (6) can detect resistance change and be in the predetermined threshold value scope, and record in the storage data of control element (6), when e-seals be unlocked without the backstage deblocking, when destroying, resistance variations surpasses (being lower than) predetermined threshold value, e-seals control element (6) record data with alert, the detected increased resistance value of control element (6) has following three kinds of states:
When A. resistance change exceeded predetermined threshold value, e-seals was the unauthorised broken state, and record data;
When B. resistance change was lower than predetermined threshold value, e-seals was illegal wire jumper serviceability, and the record related data.
When C. resistance change was in the predetermined threshold value scope, e-seals was normal deblocking, unlatching.
All relevant status informations are stored in the storage data of control element, can be accessed by background system at any time, thereby judge the legitimacy that e-seals is operated.
Claims (6)
