Abstract
The invention discloses an electronic handcuff anti-disassembling device based on IO level fluctuation. The device comprises a handcuff wrist strap, a connecting portion and a processor; the handcuff wrist strap comprises a signal line and a confusing line which are arranged around the handcuff wrist strap, and the signal line and the confusing line are the same in thickness, color and material; the handcuff wrist strap and the processor are connected through the connecting portion; and the processor comprises a wireless communication module. Whether the handcuff wrist strap is opened or not and clipped or not can be detected through the electronic handcuff anti-disassembling device in real time, and the confusing line is arranged, so that a wear can be prevented from identifying the effective signal line; and a signal line bypass is arranged to break an anti-disassembling line, and therefore it can be ensured that an electronic handcuff can correctively and effectively run.
Description
Technical field
The present invention relates to handcuffss device, be specifically related to a kind of electronic handcuff antiwithdrawal device based on the change of IO level.
Background technology
In the prior art, the one-time formed foundry engieering of employing that similar handcuffss detatching-proof system has, what have has installed the structure of tamper proof screws, but these all can not the signal that is removed to handcuffss of detecting real-time.Some technology are also had to have employed the method be injected into by supply lines in handcuffss wrist strap, detecting real-time is carried out to the state whether handcuffss are removed, but because power line requires certain width and the electric current wherein flow through is larger, be easy to be identified by wearer and be increased bypass and crack, then handcuffss can effectively be removed and detection of out-tricking.
Summary of the invention
For the deficiencies in the prior art, the invention discloses a kind of electronic handcuff antiwithdrawal device based on the change of IO level.
Technical scheme of the present invention is as follows:
Based on an electronic handcuff antiwithdrawal device for IO level change, comprise handcuffss wrist strap, coupling part and processor; Described handcuffss wrist strap comprises holding wire around handcuffss wrist strap and fascination line, described holding wire and to confuse the thickness of line, color, material identical; Described handcuffss wrist strap is connected by coupling part with described processor; Described processor comprises wireless communication module;
Described coupling part comprises the first resistance and the second resistance; The first end of described first resistance connects high level, and the second end is connected with warning pin and the first holding wire pin; The first end ground connection of described second resistance, the second end is connected with secondary signal wire pin; Second end of described first resistance and/or the second end of the second resistance are provided with fascination wire pin; Described holding wire two ends connect described first holding wire pin and secondary signal wire pin respectively; Described fascination line one end connects fascination wire pin, and the other end is vacant; Described warning pin connects described processor.
Its further technical scheme is: the resistance of described first resistance is 2M Ω.
Advantageous Effects of the present invention is:
Whether the present invention can be opened to handcuffss wrist strap, by the state of cutting off, and by arranging fascination line, avoiding wearer and identifying effective holding wire or the bypass of signalization line cracks tamper circuit by detecting real-time.The present invention is also provided with current-limiting resistance, ensures that the electric current in holding wire is very small, is difficult to detect with instrument, prevents wearer to use current detecting instrument to detect electric current, and then identification signal line, cracks tamper circuit.The present invention can guarantee that electronic handcuff system can correctly effectively run.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of coupling part.
Detailed description of the invention
The present invention includes handcuffss wrist strap, coupling part and processor.Handcuffss wrist strap comprise around handcuffss wrist strap holding wire and fascination line, then to cut off or take apart handcuffss wrist strap, then holding wire can disconnect simultaneously.The features such as the fascination color of wire pin, thickness and material are all identical with holding wire pin.Handcuffss wrist strap is connected by coupling part with processor.
Fig. 1 is the schematic diagram of coupling part.The present embodiment is provided with two fascination lines.Coupling part comprises resistance R138 and resistance R121, resistance R138 one end connects high level VDD_BT, the other end is connected with warning pin ALARM, holding wire pin TP131 and fascination wire pin TP132, resistance R121 one end ground connection, the other end is connected with holding wire pin TP133 and fascination wire pin TP134.The two ends connection signal wire pin TP131 and holding wire pin TP133 respectively of holding wire.One end of first fascination line connects fascination wire pin TP132, and the other end is vacant; One end of second fascination line connects fascination wire pin PT134, and the other end is vacant.Warning pin ALARM connection handling device.
At normal operation, holding wire pin TP131 and holding wire pin TP133 links together by holding wire, warning pin ALARM is in low level state, once handcuffss wrist strap is cut off or is removed, namely holding wire disconnects, namely holding wire pin TP131 and holding wire pin TP133 disconnects, and warning pin ALARM is driven high high level state instantaneously, and warning pin ALARM sends the state that this level changes to processor.
Spy software and wireless communication module are installed in processor.Spy software is an interrupt handling routine, when processor receives the information of warning pin ALARM level change, processor calls spy software code, after the level that spy software confirms warning pin ALARM is effectively changed, alarm signal can be sent to intelligent machine or other external equipments by wireless communication module, do further process by the latter.
Outside removing is directly cut off, handcuffss wrist strap also has a kind of common crack method, is holding wire and arranges bypass, then, after handcuffss wrist strap is cut off, holding wire, by bypass UNICOM, makes tester cannot discover handcuffss wrist strap by the situation of cutting off.But in the present invention, holding wire is only used to signal transmission, thus can do very thin, and can be when mounted, holding wire is bent repeatedly, simultaneously fascination line is set holding wire is other, because the features such as the color of holding wire and fascination line, thickness and material are all identical, then wired mixed in together, holding wire is made extremely to be difficult to identification, avoid wrist strap wearer and choose holding wire separately, bypass is arranged to it, abolish this situation of alarming apparatus.The present invention is provided with two fascination lines, also can arrange more fascination lines, increase identification difficulty.
When being difficult to directly recognize holding wire, the wearer of handcuffss wrist strap can also judge effective holding wire by the current information detected in each electric wire, in order to prevent the generation of this situation, the invention allows for more excellent technical scheme, namely the resistance of resistance R138 is set to 2M Ω, namely resistance R138 is as current-limiting resistance, can ensure that the electric current in holding wire is enough little like this, even if use instrument to be also difficult to detect, prevent the wearer of handcuffss wrist strap from detecting current information by using instrument and then judging useful signal line.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive without departing from the spirit and concept in the present invention or associate, all should think and be included within protection scope of the present invention.
