Abstract
The utility model discloses an anti-interference communication device for security. The anti-interference communication device comprises a host, a door magnet, an infrared sensor, an identity recognizer, a host communication module and an active test communication module. The host communication module is in bidirectional communication connection with the active test communication module. The host communication model sends response request signals to the active test communication module at fixed time intervals, and receives reply signals sent by the active test communication module. The active test communication module receives the signals sent by the host communication module and sends the reply signals to the host communication module. According to the utility model, an active communication anti-interference function is achieved through the host communication module and the active test communication module, and the device actively alarms when the device determines that the interference exists.

Along with society and economic development, people's living standard improves constantly, and movement of population is accelerated, and household safe consciousness is also strengthened day by day.The public security outstanding problem of society, and offender's crime means thousand is very numerous, more and more brilliant, makes people hard to guard against.Therefore,, for guaranteeing safety of life and property, increasing family has introduced intelligent means-household monitoring system.
Household monitoring system is in the market mainly by an infrared alarm main frame, and some infrared eyes, some magnetic systems and telepilot form, and considers the convenience of installation, and infrared eye, a door magnetic system generally adopt powered battery.Due to the restriction of battery electric quantity, infrared eye and door magnetic system generally adopt the relatively little mode of this power consumption of wireless unidirectional communication, and cannot carry out both-way communication, can only realize the one-way communication to main frame by sensor.When using one-way communication, main frame can be received the signal being sended over by sensor, and sensor cannot receive the signal that main frame sends, when being subject to the same frequency of high-power jamming equipment or adjacent frequency and disturbing (as intercom), main frame cannot judge whether self can also receive the signal that sensor is sent, whether therefore have no way of selecting to report to the police, may occur the situation that wrong report is failed to report, household safe coefficient reduces.
Utility model content
In order to overcome the above problems, the utility model provides a kind of anti-tampering communication device for security protection, mode by active inquiry has judged whether high-power wireless electrical interference equipment, determining while existing high-power wireless electrical interference equipment to disturb by co-channel interference or adjacent frequency, initiatively reporting to the police.
The utility model adopts following technical scheme:
A kind of anti-tampering communication device for security protection, comprise main frame, door magnetic, infrared sensor, identity recognizer, host communication module and initiatively test communication module, described host communication module is installed in described main frame, and described host communication module is initiatively tested both-way communication between communication module and is connected with described;
Described host communication module, sent acknowledges requests signal and receives the described return signal of initiatively test communication module transmission to the described communication module of initiatively testing for the interval set time;
The described communication module of initiatively testing, the acknowledges requests signal sending over for receiving described host communication module, and send a reply signal to described host communication module.
Preferably, describedly initiatively test the communication module interval set time to described host communication module transmitted signal, described host communication module receives from the described signal of initiatively testing communication module.
Preferably, described identity recognizer comprises tag card recognizer and/or Fingerprint Identification Unit and/or password identifier.
Preferably, described tag card recognizer, described Fingerprint Identification Unit all also comprise input/output module, and described input/output module also disposes for inputting the button of password.
Preferably, the described communication module of initiatively testing is installed separately, or is installed in the identity recognizer that adopts external power supply power supply.
The beneficial effects of the utility model are:
The utility model comprises host communication module and initiatively tests communication module, described host communication module is initiatively tested both-way communication between communication module and is connected with described, mode by active inquiry has judged whether high-power wireless electrical interference equipment, determining while existing high-power wireless electrical interference equipment to disturb by co-channel interference or adjacent frequency, initiatively reporting to the police.

Embodiment
Below in conjunction with the Fig. 1 in accompanying drawing, the anti-tampering communication device for security protection of the present utility model is described in further detail.
The anti-tampering communication device for security protection of the present embodiment, please refer to Fig. 1, comprise main frame 100, door magnetic 300, infrared sensor 200, identity recognizer 400, host communication module 500 and initiatively test communication module 600, described host communication module 500 is installed in described main frame 100, and described host communication module 500 is initiatively tested both-way communication between communication module 600 and is connected with described;
Described host communication module 500, to the described communication module 600 initiatively test, send acknowledges requests signals and receive the described return signal of initiatively testing communication module 600 transmissions for the interval set time, if receive return signal, do not report to the police, as do not receive return signal, report to the police; Also can arrange and not receive the number of times of return signal as the condition of warning, the number of times that does not receive return signal reaches predefined value and starts warning.Described host communication module 500 can arrange to described interval time of initiatively testing communication module 600 transmission acknowledges requests signals.
The described communication module 600 of initiatively testing, the signal sending over for receiving described host communication module 500, and send a reply signal to described host communication module 500.
The anti-tampering communication device for security protection of the present embodiment, please refer to Fig. 1, on the basis of previous technique scheme, can also be, describedly initiatively test the 600 interval set times of communication module initiatively to described host communication module 500 transmitted signals, if described host communication module 500 receives within the default time, initiatively do not test the acknowledges requests that communication module 600 is sent, think that device has been subject to disturbing and has started warning.The described communication module 600 of initiatively testing can arrange to set time at described host communication module 500 transmitted signal institute intervals.
The anti-tampering communication device for security protection of the present embodiment, please refer to Fig. 1, on the basis of previous technique scheme, can be specifically, and described identity recognizer 400 comprises tag card recognizer 401 and/or Fingerprint Identification Unit 402 and/or password identifier 403.
The anti-tampering communication device for security protection of the present embodiment, please refer to Fig. 1, on the basis of previous technique scheme, can be specifically, described tag card recognizer 401, described Fingerprint Identification Unit 402 all also comprise input/output module, and described input/output module also disposes for inputting the button of password.
