Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many other forms than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention.
The electronic commodity price tag comprises a metal fixing frame 1 and an ink screen 3, wherein the middle of the metal fixing frame 1 is hollowed out and used for exposing the ink screen 3; the back of the metal fixing frame 1 is provided with an upper support fixing section bar groove 5 and a lower support fixing section bar groove 5 which are used for fixing the whole equipment and can be fixed on the upright post through external accessories. Ink screen 3 contains protection frame 2 and back casing 7, and the transparent portion is used for the presentation of ink screen 3 content in the middle of the protection frame 2, protects ink screen 3 simultaneously, and back casing 7 is fixed around with protection frame 2 through backshell theftproof bolt 8. The rear end of the ink screen 3 is fixedly provided with a PCB (printed Circuit Board) 10, and the ink screen 3 is fixed on a section bar behind the metal fixing frame 1 through a machine core fixing anti-theft bolt 6. A joint of the PIPE antenna 4 is reserved below the ink screen 3, the PIPE antenna 4 is externally connected, and a main body of the PIPE antenna 4 is fixed on the side edge of the metal fixing frame 1.
The metal fixing frame 1 is made of an aluminum shell material, and the protective outer frame 2 is made of an acrylic plate. A front shell 9 is arranged between the ink screen 3 and the protective outer frame 2, and a switch rear cover 11 is movably arranged on the rear shell 7.
This electronic commodity price tag's battery passes through the power management chip and is 3 power supplies for drive module and ink screen, and wherein the model of power management chip is: LDO, ME6210A33PG, DC-DC SY8088AAC, PMIC, TPS651851RSLR.
The PIPE module is directly powered by a battery, and the electronic switch is controlled by the PIPE module to turn on and turn off the power supply of the driving board. The antenna is connected with the PIPE communication module, and the PIPE communication module is connected with the driving module through the parallel SPI interface. When the price information needs to be updated, after the gateway sends a price updating instruction, the PIPE module starts to receive price information data sent by the gateway, the power supply of the driving module is started after the data are received, and the display content of the ink screen 3 is refreshed into new price information through the SPI. After the update is completed, the power supply of the driving module and the power supply of the ink screen 3 are cut off, and the model of the driving module is as follows: IT8951E DX LQFP128 (14X 1.4 mm).
