Description
Technical field
The invention belongs to intelligent seal technology field more particularly to a kind of seal tamper destroying systems.
Background technique
Intelligent stamper machine reduces the workload of user, while certain by carrying out intelligent automatic management to seal
Prevent lack of competence personnel from abusing seal in degree.But traditional stamper machine does not have the measure of protection seal safety, seal is very
It is easy to be taken privately.To solve this problem, there is a kind of stamper machine with alarm module in market, when stamper machine by
It can be sounded an alarm in time when improper disassembly or malicious sabotage, improve the safety of seal.However, such seal-affixing machine according to
It cannot so guarantee the safety of seal from source, if nobody perceives alarm, seal is equally easily stolen to be taken.For this purpose, market
On have also appeared and improve seal safety using WIFI module, video camera anti-theft device or setting tamper physical mechanical structure
Measure, but the difficulty that seal is appropriated public property for personal use or dismantled only all is improved, seal can not be avoided to flow out from the root.
Summary of the invention
To solve this problem, the present invention provides a kind of seal tamper destroying system, the pin when monitoring that seal is stolen and tearing open
Chapter face is ruined, the risk that seal is illegally used is reduced.
To achieve the above object, the invention adopts the following technical scheme:
A kind of seal tamper destroying system, including tamper warning module, destruction control circuit module and destruction execution module；
The tamper warning module and destruction control circuit module are electrically connected, and tear wind open with the presence or absence of robber for monitoring seal
Enable signal is destroyed to destroying control circuit module in the presence of issuing when stealing and tearing risk open in confirmation in danger；The destruction control circuit mould
Block include the destruction controller being electrically connected with tamper warning module and with destroy controller and to destroy execution module electric respectively
Property connection destruction control switch, destroy controller and receive the destruction enable signal that tamper warning module issues, and pass through destruction
The movement of execution module is destroyed in control switch control, realizes that seal is destroyed.The destruction controller preferably destroys control monolithic
Machine, destroying control switch is preferably MOS switch.
Further, the destruction control switch is provided with delayed start-up circuit.Further, the destruction controller setting
There are delay time setting module and/or alarm module.
Further, the destruction execution module includes heating resistance wire.Further, it is additionally provided with current-limiting protection circuit.
Further, the tamper warning module includes infrared light supply and the infrared optical sensor that is correspondingly arranged.Preferably, institute
Stating infrared optical sensor includes infrared photodiode.
Beneficial effects of the present invention: mutual by destroying control module, destruction execution module, destruction warning module three parts
Cooperation realizes that seal face is destroyed when confirming that seal tears risk open in the presence of robber, and it is safe to achieve the purpose that protection is impressed.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the invention seal tamper destroying system；
Fig. 2 is a kind of light-sensitive element schematic diagram of embodiment.
Specific embodiment
The present invention will be described in detail with reference to the accompanying drawings and detailed description.
It is the structural schematic diagram of seal tamper destroying system of the present invention, including tamper warning module, destruction control referring to Fig. 1
Circuit module processed and destruction execution module.
Wherein, tamper warning module and destruction control circuit module are electrically connected, and are torn open for monitoring seal with the presence or absence of robber
Risk, when confirmation destroys enable signal to destroying control circuit module in the presence of issuing when stealing and tearing risk open.
Destroying execution module includes heating resistance wire, by high current fever meltdown seal chapter face, is additionally provided with current limliting guarantor
Protection circuit guarantees safety in utilization.Destroy control circuit module include with heating resistance wire be electrically connected MOS switch and with
Destruction control single chip computer is electrically connected in tamper warning module and MOS switch, and when destroying control single chip computer, to receive tamper pre-
When the destruction enable signal that alert module issues, control MOS switch is connected with heating resistance wire, and seal face is thoroughly melted down.Using
Single-chip microcontroller controls MOS switch, and with the use of hot melt destruction mode, can quickly melt down seal face after switch connection,
The destruction time is short, and the seal after destruction is possible there is no repairing, and it is safe that seal can be effectively ensured.
To prevent maloperation, safety in utilization is further increased, control switch is destroyed and is additionally provided with delayed start-up circuit, sell
Ruin controller and be provided with alarm module and delay time setting module, set delay time (such as 500ms, 1s, 2s, 4s,
8s, 10s etc.) after, if destroying control single chip computer receives destruction enable signal, can first alarm, at this time delayed start-up circuit
It does not turn on, until being just connected after reaching delay time, then carries out seal destruction.
As one embodiment of the present invention, the tamper warning module includes infrared light supply and is correspondingly arranged infrared
The displacement signal of components in seal disassembly process is converted to electric signal using photoelectricity transformation principle by light-sensitive element.To avoid
Because shell loosens, causes to judge by accident, certain deflection yoke is set between infrared light supply and infrared optical sensor, is preferably provided with simultaneously
Infrared optical sensor more than two.The setting orientation of infrared optical sensor is moved according to the necessary components that seal disassembly may occur
Emotionally condition determines, for example, scalable trigger element can be arranged by wall inside the shell, more than two infrared optical sensors are arranged
On the different location of scalable trigger element, in seal normal use, infrared light correspondence is radiated on infrared optical sensor,
When seal is disassembled, the movement of shell makes scalable trigger element drive infrared optical sensor mobile, causes infrared photosensitive member
The received infrared light intensity of part changes, and both ends output voltage generates difference, which is converted to destruction enable signal
Single-chip microcontroller is output to be handled.To realize above-mentioned control process, can be realized using light-sensitive element shown in Fig. 2, it is photosensitive
Area is two infrared photodiodes in parallel, and SIG1 and SIG2 are the two-way voltage signals of output.Infrared light is radiated at sense
When light area, the resistance value very little of two infrared photodiodes, resistance R1 and R2 partial pressure are larger, and the voltage signal of SIG1 and SIG2
It remains unchanged.When infrared light is blocked, infrared photodiode receives the strength reduction of infrared light, so that resistance value increases, makes
It changes at the output voltage at the both ends SIG1 and SIG2, which is converted to destruction enable signal and is output to monolithic
Machine is handled.The conversion regime of voltage change signal is not particularly limited in this programme, can use side well known in the art
Method, such as be converted to by hysteresis loop comparator and destroy enabling pulse signal.
The above examples are only used to illustrate the technical scheme of the present invention and is not intended to limit it, all without departing from the present invention
Any modification of spirit and scope or equivalent replacement should all cover in the range of inventive technique scheme.
