Abstract
An electronic shelf label (ESL) system has a wake-up function using magnetic field detection, which detects a magnetic field output from an input unit, e.g. reader, and allows an ESL in a sleep mode to automatically wake up when the input unit approaches the ESL. Included is an input unit (10) having a magnetic field generation unit (11), an ESL (20) having a magnetic field detection unit (21) detecting the magnetic field generated by the generation unit, and a communication module (22) waking up and communicating with the input unit when the field is detected by the detection unit. The detection unit may be a Hall sensor generating a voltage corresponding to an intensity of a magnetic flux when the latter is generated. The detection unit may repeat a wake-up mode and a sleep mode according to a first period, and the communication module may repeat a wake-up mode and a sleep mode according to a second, longer, period.

Therefore, the ZSL receives power using a coin battery or the like. tocordingly, it is very important to reduce the power consumption of the E$L itself in order to continuously use the ESL for several years (a,gt, 5 years or snore) while only using * single battery.

S £0036] The magnetic field datection unit 23. may repeat a sleep pode and a wake-up mode according to a preset first. period so as to reducepower consujnptjon. That is, the magnetic ditection unit 21 repeats the sleep mode and wake-up mode by periodically stipplying or cutting oft a pair voltage or power current to the magnetic field detection unit 21. Since the conununicatiot module 22 should wake up immediately according to a user' s demand, the wake-up period of the magnetic field detectiox wiit 21 may be set to be relatively short a L00271 The communication module 22 may include a switch unit 22l a rnicreprocesor (MCZI) 222, and a transceiviar 2fl tim switch imit 2Z3. aflows.a power voltage or power current provided tram the power siapplyunit 23 to be supplied or cut of f according to whether a magnetic field is detected by the magnetic field detection wilt 21 The micz'oprtceasor 222 operates by receiving the power voltage or power current through the switching operation of the switch unit 231, and controls the overall operation of the ES1, 20. The transceiver 223 crpetates by receiving the power voLtage or power current through the switching operation of tte switch mit 221, arid wirelessly ccttuüaiCateS iitith the input unit 10.

That is1 in the case where the magnetic field detection unit 21 is ccmtigured with the hail sensor as illustrated Sn FIG. 3, the output voltage 7q outpitt from the hail sensor may be used as the control signal of the switch unit 221. U the output voltage Va output from the hall sensor is higher than a preset reference voltage, th switch unit 221 determines that the input unit 10 exists at a position adjacent thereto, and connects the power supply unit 23 to the transceiver 223 and the.xai 222. Thus, the powtt voltage or power Curreflt is supplied. ta the transceiver 223 and the ptT 222 to thereby wake up the commimi cationmodtle 22.

(0034] After the tenain*tLon of the initializing operatou ($41.), a transce$ytng ç,peraflon gr receiving 4ata related to convents tt be ieplayed on the LCD 25 is pertonied by the transceiver 223 ($42), and information corresponding to the data received by the LCD. driving unit 24 is updated to the LCD Page 12 (343). me data transceiving operatton (2) may be performed by wireless communication network to which the Z$Z.
belongs, or by a portable input unit 10 of a manager like the ESL systent according to the embodiment of the present invetmtign.
(0935] During the $nitializing operation ($41), the data transceiving operation (342), and the LCD updating operation ($3), the switeti tmit 221 keeps its connection state Sfl: order for thepower supply unit 23 to supply the power voltage qr power current to the Met) 222 or the transceIver 223.
£00363. As the initializing operation 34l), the data tratceiytng operation (242) and the LCD updating operation (233 are performed, information, for goods to be displayed on the LCD 25 of thi ESt 20 is diS1ayed. Then, the switch unit 221 cuts off the power vottage or powet current *upplied. .Vxom the power unit 23, aflotnq the. communicat ion module 22 to enter a sleep mode (s443. The tration of the Sleep mode ($44) may be determitted &ccordinc to the second period, i. e *, the wake-up period determined by a wireless cuamutsication:networ)c incl'uded In theESL2O Also, during the.sleep mode (244), themagnetic field detection unit 21 tries to detect a peripheral magnetic field while repeatedZy waking up at every first pexio& (09373 As illustrated in 11G. 4, if the sleep mode is continued according to the preset second period even after the duration of the sleep mode (645), the magnetic detection unIt 21 tries rage ia to detect a peripheral magnetie field (S46). If th magnetic detection unit 21 detects a magnetic field, the switch, unit 221 may wake up the communication module 22 by supplying the power voltaqe or power currtt to the MCU 222 and the transceiver 223 tram the power supplyunit 23 ($4flt The waken-up cosuflitatibu zuodule 22 detertaines tether data to be transcelved by the adjacent input unit 10 exist or not (S48} It the data exist the data transceiving operation tS4Zj is performed, and it data do not exiat the canmuxztcation module 22 enters the sleep m!=e again tS44).

IL the data exist, the data transceiving operation (942) is perfortted, and if data do not exist, the coitunitation module 22 enters the sleep todt aflitt 44) 100391 Accordjng to the embodiment of the present inventjon, gfl can wake up automatically by detecting a magnetic field generated fran an input 4eviae without manual triggering when Page 14 the input unit tratsneitt big data exists near the ESI, thateby re4ucing an operator's inconvettence.
