Abstract
The utility model discloses a restaurant positioning system based on an RFID (radio frequency identification device). The restaurant positioning system based on the RFID comprises an active RFID label, an RFID reader, a CAN (controller area network) bus, a network device and a background computer; the active RFID label and the RFID reader are connected in a coupling manner through wireless radio frequency signals and spaces; the RFID reader and the CAN bus are electrically connected; the CAN bus is electrically connected with the network device; and the network device is electrically connected with the background computer. The restaurant positioning system based on the RFID, provided by the utility model, can easily position the positions of customers of a restaurant, has high adaptability to the environment, and is still can be used continuously after the restaurant layout is changed.
Description
Technical field
The utility model relates to a kind of locating device, particularly a kind of dining room positioning system based on RFID.
Background technology
Now a lot of dining room such as chafing dish restaurants, fast food restaurant and western-style food shop etc. are larger because managing area, table number is more, flow of the people is also large at noon or when having dinner evening, customer's location occurs after the meal often, waiter can't find seats in a restaurant, client place, the result that this situation causes is: increase the food delivery staff, increase human cost; Increase food delivery person's work difficulty and intensity, affect work efficiency; Increase client and wait for the meal time, easily cause client to produce the complaint mood to the dining room, affect dining room image and prestige.
The utility model content
The technical matters that the utility model solves is for existing deficiency, to provide a kind of dining room positioning system based on RFID.Radio RF recognition technology (Radio Frequency Idenfication, be called for short RFID) be a kind of non-contacting automatic identification technology, its ultimate principle is to utilize radiofrequency signal and Space Coupling (inductance or electromagnetic coupled) transport property, realizes being identified the automatic identification of object.
Rfid system comprises electronic tag and reader two parts at least.Electronic tag is the data carrier of radio-frequency recognition system, and electronic tag is comprised of label antenna and label special chip.According to the difference of electronic tag power supply mode, electronic tag can be divided into active electronic label (Active tag), passive electronic label (Passive tag) and half passive electronic label (Semi-passive tag).Battery is housed in active electronic label, and passive RF label does not have internal battery, and half passive electronic label (Semi-passive tag) part relies on battery operated.
Electronic tag can be divided into low-frequency electronic label, high-frequency electronic label, ultrahigh frequency electronic tag and microwave electron label according to the difference of frequency.Difference according to packing forms can be divided into special-shaped label of credit card label, linear label, paper shape label, glass tube label, circular label and specific use etc.
RFID reader (read write line) carries out radio communication by antenna and RFID electronic tag, can realize reading or write operation tag recognition code and internal storage data.Typical reader includes high-frequency model (transmitter and receiver), control module and reader antenna.
The technical solution of the utility model is: a kind of dining room positioning system based on RFID is provided, comprise active RFID tag, RFID reader, CAN bus, the network equipment and background computer, described active RFID tag is connected with Space Coupling by radio frequency signal with the RFID reader, described RFID reader is electrically connected to the CAN bus, described CAN bus is electrically connected to the network equipment, the described network equipment and hind computation mechatronics.
Described active RFID tag is taked the 2.4G frequency range.
Described RFID reader is at least three.
The described network equipment and background computer connected mode can be wired mode, also can be wireless mode.
Described background computer includes application software and database.
The beneficial effects of the utility model are: can be easy to navigate to the position at client place, dining room, and stronger to the adaptability of environment, still applicable when the dining room layout changes.
Description of drawings
Fig. 1 is hardware system structure block diagram of the present utility model.
Fig. 2 is systematic schematic diagram of the present utility model.
Fig. 3 is dining room of the present utility model schematic layout pattern.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment
as shown in Figure 1, a kind of dining room positioning system based on RFID, this system comprises active RFID tag 1, RFID reader 2, CAN bus 3, the network equipment 4 and background computer 5, described RFID reader 2 storage inside the positional information of self, and can send to information the active RFID tag 1 that enters in RFID reader 2 reading ranges by the mode of wireless transmission, when when having three or three above RFID readers that self-position information is sent to same active RFID tag 1, active RFID tag 1 by with RFID reader 2 between communicate by letter and can measure distance between active RFID tag 1 and RFID reader 2, and calculate self-position information according to this information, then by radioing to RFID reader 2, RFID reader 2 is transferred to the network equipment 4 to the positional information of active RFID tag 1 by CAN bus 3, the network equipment 4 is processed data transmission to background computer 5.Background computer 5 provides the service about label position by label information.
As shown in Figure 2, be systematic schematic diagram of the present utility model, comprise the RFID Transmit-Receive Unit, main control unit, computer background processing unit, power module.The RFID Transmit-Receive Unit comprises active RFID tag and RFID reader, both all are operated in the 2.4G frequency range, between active RFID tag and reader, by wireless connections, main control unit is communicated by letter by RS232 with computer processing unit, and power module provides circuit required power supply.
be illustrated in figure 3 as dining room of the present utility model schematic layout pattern, reader can be arranged on the top, dining room, three readers are placed in different positions, label can be embedded on dining table number plate of the personnel of having a dinner, after client enters the dining room, get a dining table number plate that contains label, after dining table number plate is put on dining table, when entering in the reading range of three readers and reader communication, and determine the positional information of oneself according to the communication of three readers, information is issued reader, reader is given the network equipment communication, the network equipment is given background computer communication, background computer is processed real-time display label positional information by software, so just facilitated the attendant to find accurately client's position.
The above has done exemplary description to the utility model by reference to the accompanying drawings; but the utility model is not subject to the restrictions described above; in Fig. 3; it is first-class that reader also can be placed on wall; so it is improved to utilize method design of the present utility model to carry out, all at claim protection domain of the present utility model and so on.
