A kind of directed access door
Technical field
The utility model belongs to logistics and stream of people's control field in the places such as gateway, storage, buildings, particularly relates to a kind of directed access door.
Background technology
Access door is applied to the Detection & Controling of the stream of people or logistics usually, the effect of play safety precaution, keeping order.Some access doors (utility model grant number: CN 203535703 U, CN 201602041U, CN2680839, CN2780951) carry out Detection & Controling to the stream of people and logistics, are applied to the control of the places such as scenic spot, station, airport, harbour, public transport subway to the stream of people and logistics.These application scenarios allow the stream of people, logistics way moving usually, and above-mentioned access door cannot differentiate the direction of the stream of people, logistics, more cannot differentiate the stream of people, the delay of logistics, the phenomenon such as to hover.
Under some special occasions, the outlet of such as parking lot, logistics warehouse, walkway and entrance, the feature of these passages only allows one-way movement, do not allow reverse movement, do not allow people, thing is trapped in passage proximate for a long time.These application scenarios, require that access door can not only identify the stream of people or logistics, also must can provide the motion trace data of the stream of people, logistics, are the direction of motion of application system identification people, thing, find to be detained, hover, the phenomenon such as to turn back provides foundation.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of directed access door.
The purpose of this utility model is realized by following technical scheme:
A kind of directed access door, comprising:
Audible-visual annunciator, keel shoe, RFID antenna, TNC connecting line and rfid interrogator;
Described RFID antenna and rfid interrogator are arranged on described keel shoe, and a described RFID antenna is at least installed in every side of directed access door;
Described audible-visual annunciator is installed on the both sides of described keel shoe or top or bottom, and is connected with described rfid interrogator.
Compared with prior art, one or more embodiment of the present utility model can have the following advantages by tool:
Structure is simple, support is reported to the police; But also the RFID label tag that can identify through directed access door, obtain the EPC numbering of RFID label tag, obtain the movement locus of RFID label tag through access door both sides.
Accompanying drawing explanation
Fig. 1 is the structure of directed access door;
Fig. 2 is the Application Example of directed access door.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail:
As shown in Figure 1, illustrate the structure of directed access door, comprising: keel shoe 1, audible-visual annunciator 2, RFID antenna 3, TNC connecting line 5 and rfid interrogator 4; Described RFID antenna and rfid interrogator are arranged on described keel shoe; Described audible-visual annunciator is installed on the both sides of described keel shoe or top or bottom, and is connected with described rfid interrogator.
Above-mentioned TNC connecting line two ends are connected with RFID antenna and rfid interrogator respectively.
Above-mentioned RFID antenna at least includes two, and a described RFID antenna is at least installed in every side of access door, the wireless radio frequency identification signal that every side of access door is all at least launched by 1 RFID antenna cover.
Above-mentioned rfid interrogator possesses a GPIO port, an Ethernet interface and a serial ports, for the motion trace data of sender, thing, and controls audible-visual annunciator and sends alerting signal.
Above-mentioned audible-visual annunciator is connected on the GPIO port of described rfid interrogator.
As shown in Figure 2, the embodiment of directed access door is: specify the people of directed access door, thing direction of motion is a->b->c.The keel shoe of directed access door has been installed three RFID antenna, and the wireless radio frequency identification signal that RFID antenna is launched covers a, b, c region of access door both sides respectively, and can there be overlapping region in these three pieces of regions, also can zero lap region.
When carrying the people of RFID label tag, thing through directed access door, successively through c, b, a region, application system judges people, thing drives in the wrong direction, and controls audible-visual annunciator and sends alerting signal; If successively through a, b, c region, it is legal direction of motion that application system judges.
Although the embodiment disclosed by the utility model is as above, the embodiment that described content just adopts for the ease of understanding the utility model, and be not used to limit the utility model.Technician in any the utility model art; under the prerequisite not departing from the spirit and scope disclosed by the utility model; any amendment and change can be done what implement in form and in details; but scope of patent protection of the present utility model, the scope that still must define with appending claims is as the criterion.
