Description
Technical field
This utility model relates to a kind of key warning system, particularly a kind of simple and practical ultrahigh frequency RFID key warning system.
Background technology
In daily life, often occur forget on door by key or look about the thing of key, such as because but door has been locked in worried working has forgotten to pull key, owing to the volume of key is very little, it is just that key chain is also easily fallen in the place being not easily seen, being away from home, key is also easily lost or stolen. For anti-theft and finding key, market occurring in that, key is tracked and record by two schemes, the first is that the key chain adopting and the functions such as GSM, GPS, GIS, bluetooth being integrated into one is by wireless signal real-time tracking key, although this mode is powerful, but there are four reasons can cause the inconvenience in life: one is that the mode of key chain is widely known by the people, and key chain can directly be lost by the people taking key; Two be track and localization due to the accuracy problem of technical limitations, in the small-sized complex environments such as family, it is not easy to search out key; Three is that this scheme needs timing to change compact battery, because the electricity sending positional information needs is a lot; Four is expense, buys Mobile phone card to use GSM network to need, uses cellular service. The second is to use high-frequency RF ID Technology design key management box, this method is that high frequency RFID reader is placed in each position in an internal medium, when key occurs in the scope of this reader, reader automatically reads and uploads the time of reading, following the tracks of the path of key in this way, but this mode also has two shortcomings: one is that the method can only carry out in a closed environment, two is want placement reader as much as possible, cost is high, poor practicability.
Utility model content
Technical problem to be solved in the utility model is in that to provide a kind of less costly, simple and practical ultrahigh frequency RFID key warning system, is convenient for people to give key for change, overcomes prior art not enough.
For solving above-mentioned technical problem, the technical solution of the utility model is as follows:
A kind of ultrahigh frequency RFID key warning system, it is made up of ultra-high frequency RFID label and rfid interrogator two parts, and ultra-high frequency RFID label is fixedly connected on the shank of the key, and rfid interrogator is placed in mobile phone draw-in groove; Being provided with alarm modules of locking a door, location alarm modules and alert control module, alarm modules of locking a door and location alarm modules in mobile phone and connect alert control module, alert control module connects rfid interrogator; Lock a door alarm modules and location alarm modules are respectively arranged with vibration alarm device, audio alarm and flicker warning devices.
In above-mentioned ultrahigh frequency RFID key warning system, it is preferred that ultra-high frequency RFID label adopts passive ultra-high frequency RFID label, rfid interrogator adopts SD card-type rfid interrogator, and rfid interrogator is placed in mobile phone SD draw-in groove.
Beneficial effect: compared with prior art, core technology of the present utility model is based on ultra-high frequency RFID technology, and this technology can ensure that middle distance wireless communication is unobstructed, avoids the dependence to electric energy of the tracked end as far as possible, reduces energy consumption. This utility model needs passive ultra-high frequency RFID label is attached to the shank of the key when in use, SD card-type rfid interrogator is placed in mobile phone SD draw-in groove, the distance of mobile phone and key is judged by reading the energy power of signal, then corresponding alarm, the problem that prompting key owner quickly processes key are realized. This utility model has the following characteristics that the passive ultra-high frequency RFID electronic tag that (1) adopts does not need supporting power supply, and energy consumption is low; (2) ultrahigh frequency RFID key warning systems can manage the key of multiple electronic tag simultaneously, it is easy to extension, easy to use; (3) system is smaller and more exquisite, hidden, it is to avoid life inconvenience; (4) system cost is low, low in energy consumption, simple and practical; (5) automatically being identified destination object by radio frequency identification signal and obtain related data, without manual intervention, recognizable high-speed moving object also can identify multiple RFID tag simultaneously, swift and convenient to operate.

Fig. 3 is system pie graph of the present utility model.
Below in conjunction with the drawings and specific embodiments, this utility model is further described.
Detailed description of the invention
Embodiment 1. As shown in Figure 1, it is made up of ultra-high frequency RFID label and rfid interrogator two parts, ultra-high frequency RFID label adopts passive ultra-high frequency RFID label, passive ultra-high frequency RFID label is pasted onto on the shank of the key, rfid interrogator adopts SD card-type rfid interrogator, and rfid interrogator is placed in mobile phone SD draw-in groove. As it is shown on figure 3, be provided with alarm modules of locking a door, location alarm modules and alert control module in mobile phone, alarm modules of locking a door and location alarm modules connect alert control module, and alert control module connects rfid interrogator; Lock a door alarm modules and location alarm modules are respectively arranged with vibration alarm device, audio alarm and flicker warning devices.
Operation principle: this utility model can realize two functions: one is alarm of locking a door; Two is location alarm, and every kind of alarm has three kinds of type of alarms: vibration alarm, audio alarm, flicker alarm. The realization of its function judgement that to be based between rfid interrogator and ultrahigh frequency RFID electronic tag signal strong and weak, when the signal is strong, illustrates that distance is closely between the two;When signal is weak, illustrate that distance is remote between the two, realizes the realization to the anti-lost of key and positioning function by both modes. Under conventional sense, system default is locked a door alarm, if desired for finding key, then can manual switching to positioning alarm function. System implements process such as shown in following two examples:
(1) when making employment lock the door away, if key does not pull out from door, when making employment exceed restriction distance (generally can set that about 4m), mobile phone will indicate that lamp flicker/vibrations/jingle bell is reminded, and warning makes employment forget the key pulling out on door; (2) when make employment have forgotten key somewhere time, then can handheld mobile phone, function is switched to location warning mode, move in the position being likely to lose, when rfid interrogator and ultrahigh frequency RFID label signal transmit, it indicates that lamp flicker/vibrations/jingle bell is reminded, and along with distance between the two is shorter and shorter, remind frequency or intensity to be stepped up, help the determination to key position.
Embodiment of the present utility model is not limited to above-described embodiment, and the various changes made under the premise without departing from this utility model objective belong within protection domain of the present utility model.
