To shown in Figure 4,1 is the location terminal bodies referring to Fig. 2; 2 is the changeability bend pipe; 3 is reflector; 4 are the location terminal; 5 is testee.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the utility model is drawn together main frame mainly by processor, LCD lcd touch display, and the AC97 sound card, the WIFI module, the MCU one chip microcomputer, infrared module, the RF module is formed, and bar code reader is formed.
Processor is the S3C6410 chip based on the ARM11 kernel, the built-in DDR internal memory that is used to deposit the NAND FLASH internal memory of code and data and is used for operation code, and save as the activation member of 256M in the NAND FLASH, and main frame adopts WINCE 6.0 Embedded System Design as main frame.
Because service terminal can be installed on the shopping cart in sub-supermarket and also can carry, so adopted 10.2 cun widescreen LCD, adopts touch mode of operation in addition, so be furnished with corresponding touch-screen.
Present existing similar products generally adopt ultrasonic wave location, light track and localization, WIFI location, bluetooth location, indoor GPS location.
Ultrasonic wave location will rely on the testing base station on three or the above horizontal level just to determine the position of a positioning equipment, in shelf such as market, indoor environment that personnel are numerous, and ultrasonic wave or be blocked, reflect, the ultrasonic wave location can not be carried out.Ultrasonic wave location will rely on radio to communicate by letter and could work between positioning equipment and testing base station, and cost is higher.When positioning equipment was numerous, mutual interference was also comparatively serious.
The light track and localization traces into positioning equipment by detector, requires between positioning equipment and the detector linear visual; A detector can only be followed the tracks of an equipment in a time, when positioning equipment more for a long time, the light track and localization can't position each equipment; The data that the light track and localization obtains are at the detector end, owing to can't distinguish the identical positioning equipment of profile, so locator data is invalid.
The WIFI location positions by the decay of WIFI signal and the relation of distance, and this mode positioning accuracy is low, and the decay of WIFI signal and barrier and air humidity all have relation in addition, so its accuracy is affected by environment big.
The bluetooth location is subjected to the influence of barrier and air humidity equally, and precision is low, and the bluetooth positioning cost is very high in addition.
The indoor GPS location, because the positioning accuracy of GPS itself is just very low, gps signal is in the big within doors high attenuation of building, in order to obtain higher signal sensitivity, just need to prolong the time of staying in each code delay, so the indoor GPS location, positioning accuracy is low, the location time-delay is big, and cost height and power consumption greatly also limit its application in addition.
And the utility model employing is infrared location technology, realize location to product will containing infrared carrier signal and converting the RF signal to by infrared commentaries on classics RF module, can directly connect infrared remote control, convert wireless transmission to, wireless transmission distance can reach more than hundred meters.
As shown in Figure 2, location terminal 4 is housed above the shelf of super incity, location terminal 4 is locating information reflectors, comprises location terminal bodies 1, changeability bend pipe 2 and reflector 3, and location terminal bodies 1 comprises control circuit and power supply.Changeability bend pipe 2 is convenient position and directions of adjusting reflector, and this part also can be omitted.Reflector 3 is the parts that send locating information, and the reflector 3 general infrared emission heads that adopt are as original paper.
Realize the location in big zone, just need a plurality of location terminal to form transmitting base station.The locating area of single location terminal is round, accomplishes region-wide location, needs overlapping locating area, and the combination of transmitting base station is including but not limited to the form of accompanying drawing 3.In the overlapping region, the coordinate of positioning equipment is averaged.In use the adjacent times of transmitting several or several groups of location terminals need be staggered, avoid the signal of overlapping region to disturb.Because the framing signal of location terminal is the vertical direction transmission, efficiently solve shelf, the interference of personnel to locating.
Terminal of the present utility model is bound intrasystem position and each or every group of ID that locatees terminal, location terminal emission is than the id information alternative site information of short data, shortened launch time, reduce the transmitting power of emission terminal, also in order to reduce the occurrence probability of interference.
As shown in Figure 4, location terminal 4 utilizes infrared transmission mode or similar fashion emission to contain the signal of locating information, location terminal 4 is placed on the top of testee, downward radiation is the zone necessarily, when being in its radiation areas by side object 5, infrared module can receive the radiofrequency signal of location terminal 4, and become the RF signal by the RF module converts, carry out Signal Processing through the MCU one chip microcomputer then, and the result after will handling sends processor to, and terminating machine is according to receiving the position that locating information is determined testee.Difference in height is relevant between the locating area size of location terminal 4 and emission angle, location terminal and positioning equipment, and it is the positioning accuracy of locating terminal that the round diameter of locating area is generally three meters.
It is long-range with new and safeguard that a kind of customer service terminal that the utility model provides, the LAN data that the wireless network module by WIFI comes reception server to provide are carried out system or data.The utility model can allow client according to oneself the merchandise news that needs to select, watch or report needs, and the locating module of taking is not only simple in structure, with low cost, good stability and accuracy is higher compared to existing technology.
