Abstract

A safety protection alarming system capable of automatically identifying identities and alarming for illegal intrusion includes that a computer or a single-chip system or a logic processor judges if the output information of traditional safety protection equipments and RF ID monitoring at the same monitor region is the illegal intrusion or a legal enter and alarming for the illegal intrusion.

Description

Automatically the identification identity is also judged the safety alarm system that trespasses

Affiliated technical field

What the present invention relates to is a kind of safety alarm system, the specifically a kind of warning system that can distinguish internal staff and cracker.System normally enters the monitored area to inner staff and only writes down and do not report to the police, and can in time send alerting signal to entering then of illegal invasion person.

Background technology

Along with science and technology development, traditional guard and alarm field begins to occur numerous safety alarm systems based on different technologies,, induction type alarm device antitheft such as infrared ray or the like.These The application of new technique provide favourable support for safeguarding work, yet these technology also exist a common shortcoming: promptly can't differentiate " enemy and we ", external cracker triggers alarm, and the staff of our unit or night watching security personnel enter monitoring range and also can trigger alarm.In order to prevent internal staff's false touch alarm, can only after opening, safety device forbid that anyone enters the relevant range, this has brought trouble for normal business and security work, has influenced the efficient of work.

Summary of the invention:

The objective of the invention is provides a kind of intelligent safety alarm system that can discern identity at the problems referred to above.This system can send alerting signal to illegal invasion targetedly, and normal discrepancy of internal work personnel and security personnel can not be triggered alarm during guarded region.This just effectively prevents that the internal staff from triggering the false alarm phenomenon that causes, under the prerequisite of guaranteeing the normal operation of warning system, native system greatly facilitates the routine work of these units.

The present invention divides detection, information processing, alarm three big modules.The unlatching of the output signal of detection module control alarm after message processing module is handled.

Detection module is made up of Safety defence detector (1) and RFID identity recognizer (3), and Safety defence detector (1) is identical with the supervision scope of RFID identity recognizer (3).

Safety defence detector (1) can be an infrared anti-theft device, also can be other circumferences or Zonal moving body sniffer formula detectors such as video, induction.Safety defence detector when the people enters the supervision scope (1) is triggered and sends a unusual fluctuation signal to message handler (2).

RFID identity recognizer (3) can receive in certain distance and be worn on the radio-frequency identification code that staff's radio frequency ID (identity number) card (4) is on one's body sent based on the principle of radio-frequency (RF) identification.Radio frequency ID (identity number) card (4) is made up of pin-saving chip and radiating circuit, the radio-frequency identification code of every card forms one-to-one relationship with the staff who wears card, so the radio-frequency identification code that sends by RFID identity recognizer (3) received RF ID (identity number) card (4) of system just can be judged the staff's who wears this card identity.

When the staff who wears radio frequency ID (identity number) card (4) entered the supervision zone, RFID identity recognizer (3) received the radio-frequency identification code that radio frequency ID (identity number) card (4) is sent, and sends the signal that receives to message handler (2).And if undisclosed illegal invasion person swarms into, because do not wear the radio frequency ID (identity number) card, RFID identity recognizer (3) just can not be triggered, and also can not transmit signal to message handler (2).

Message handler (2) can be a computer system, also can be based on record, analysis, the opertaing device of single-chip microcomputer, if do not need writing function, simple logic control circuit also can meet the demands.Message handler (2) comes recording events and has determined whether the cracker by the signal that receives above-mentioned two-way detecting module and send.At first, your entering all will be triggered Safety defence detector (1), and the internal work personnel that only wear radio-frequency identification card just can trigger RFID identity recognizer (3) simultaneously, so message handler (2) method that can judge between right and wrong according to the output signal of above-mentioned two-way detecting module is invaded or the internal work personnel normally enter the supervision zone, thereby determines that according to the rule of prior setting whether opening warning horn (5) gives the alarm.Such as having only Safety defence detector (1) to be triggered in the two-way detecting module, then can judging extraneous the forcible entry arranged, message handler (2) will be opened warning horn immediately.

The access period information that further, can comprise the internal work personnel in the rule that message handler (2) is set in advance.Can only enter the supervision zone between at 4 in afternoon at 8 in the morning such as certain staff, when if RFID identity recognizer (3) detects the identification code that radio frequency ID (identity number) card that these personnel wear sends in this period so, message handler (2) all will be judged to be normally, and recording events is for future reference simultaneously.And if the identification code that the radio frequency ID (identity number) card that the time detecting of RFID identity recognizer (3) outside this period worn to these personnel is sent, message handler (2) will be opened alarm immediately.

Summary is got up, when entire system operates.If the internal work personnel normally enter guarded region, Safety defence detector (1) is just given (2) unusual fluctuation signals of signal processor, RFID identity recognizer (3) has also sent identification signal to signal processor (2) simultaneously, and signal processor (2) can not trigger alerting signal according to rule.If unauthorized person enters, then signal processor (2) is had to the trigger pip of Safety defence detector (1), opens alarm (5) immediately according to rule and reports to the police.

The invention has the advantages that: modern design, traditional safety detection technology is combined with radio RF recognition technology, identity and the intelligent alarm function that forcible entry is reported to the police have creatively been realized to judge automatically, thereby eliminate false alarm and unnecessary confusion, guarantee staff's operate as normal, improve the level and the efficient of management and security.In addition, the present invention can realize on the existing warning system basis of repacking, effectively protect the investment of existing equipment.

Embodiment

The present invention is a kind of by automatic identification identity and judge whether to send the safety alarm system of alerting signal.According to the present invention, the embodiment of System Operation is described as follows:

At first, set card, set up personnel and the one-to-one relationship of wearing and blocking, determine admittable regulation and input information processor simultaneously for the internal staff that may enter the supervision zone allots radio frequency.Must wear identification card when requiring the staff to enter the supervision zone.

Safety defence detector and RFID identity recognizer are installed in the supervision scope then, and the effective supervision zone of the two should be the same area.Above-mentioned detector and recognizer are connected with alarm with message handler.

Following implementation step please also refer to the system's composition diagram of accompanying drawing 1 and the process flow diagram of accompanying drawing 2:

Embodiment 1, as the staff who wears radio frequency ID (identity number) card (4), when entering the supervision zone:

At this moment, Safety defence detector (1) and RFID identity recognizer (3) move as step S1.Then, detect the information that unknown object enters, be transferred in the message handler (2) as step S2 Safety defence detector.Simultaneously, RFID identity recognizer (3) receives the identification code of radio frequency ID (identity number) card (4) emission, and sends the signal that receives to message handler (2).As step S3, message handler (2) is made the judgement that the personnel of entering are authorized persons.At last, note staff's identity and entry time as step S4 message handler (2).In the case, alarm (5) does not receive alerting signal, will not send alarm sound.

Embodiment 2, when illegal invasion person enters search coverage:

Identical the from the 1st to 2 step such as the embodiment 1.At step S3, owing to there is not RFID identity recognizer (3) that radio frequency ID (identity number) card signal is transferred to message handler (2), message handler (2) will be made the judgement of the personnel of entering for the unauthorized personnel.Last message handler (2) will send a signal to alarm (5) as step S5, and alarm (5) sends alerting signal.

The present invention has a wide range of applications in every profession and trade, has considerable social benefit and economic benefit.Such as the logistics warehouse does not allow the idler arbitrarily to come in and go out for security consideration, and the warehouse often has staff's turnover simultaneously, and this has just brought trouble to security protection work.If common infrared protection alarm device is installed, the frequent staff such as porter that come in and go out can often trigger warning device inevitably and cause wrong report.If employing the present invention, then the porter can freely come in and go out, and in a single day illegal effractor enters and will in time be found.
