1. General
Radio Frequency Identification RFID
is the acronym for radio frequency identification, commonly known as RFID.
Radio Frequency Identification RFID is a non-touch automatic identification
technology, radio frequency signal through the automatic target recognition and
access to relevant data, to identify without human intervention, it can work in
a variety of harsh environments. RFID technology can identify the high-speed
moving objects, also identify multiple tags, the operation is quickly and
conveniently.
Shenzhen eTel technologies co., ltd.
according to market demand of the wireless internet of things GPRS RFID,
develop ET7138 RFID GPRS Module, it able to real time send RFID TAG information
via the GPRS network to data center. Data center platform will receive the data
and save into database, users can just use browser to access data and view all
information.
ET7138 RFID GPRS module is mainly
applied to RFID TAG information send to center via GPRS network, it help user make
minimizes R&D, and providing stable, high-speed wireless transmission
channel.
2. Feature
· Industrial Design
ET7138 GPRS Module is industrial design which built-in
watchdog chipset to ensure the system work continuously, Watchdog monitoring the
GPRS module and CPU all the time, if the GPRS module or CPU does not response
for long time, Module will restart automatically. Module is very suitable for
long-term continuous work applications.
· Main and backup data center
ET7138 GPRS Module support main and backup data center, user can set both
main data center IP address or domain name, when Module fail to connect with main data center, it will
try to connect backup data center automatically.
· TAG buffer
ET7138 GPRS Module can save the TAG card information in the NVRAM buffer,
if the GPRS network is abnormal, the Module will save data in the NVRAM, when
the network returns to normal, the data will be sent immediately. NVRAM has
feature for save data even power lose, so even Module power lose, Tag data will
still save in the NVRAM. Reader buffer can save max 2000 TAG information.
· TAG Packet Series Number
All TAG data packet include serial number, Data center need to reply a
corresponding serial number of the ACK packet after received TAG packet, Modules
receive the ACK packet, then delete the TAG information from the buffer,
otherwise it will resend TAG packet (as specified time interval and frequency).
This feature is based on the GPRS network feature, to ensure TAG data doesn't
lose.
· SMS Remote Restart
ET7138 RFID GPRS Module supports SMS remote control, users
can query the device working status through SMS, and also user
can reboot Module through SMS.
· DO port programmable output
ET7138 RFID GPRS Module DO (digital output) port supports programmable
output, according to the requirement of user site, the level of output level,
switching time, times would be programmable.
· Clock synchronization
ET7138 Module support clock synchronization; it can read the clock from
SMS or get clock from management platform by GPRS.
· Graphical configuration software
ET7138 RFID GPRS Module provides full graphical
software configuration, easy to use, and supports import or export
configuration file; so users just simply click a few icons to quickly setup RFID
system.
4.Applications
ET7138 RFID Reader products can be used for many industrial applications, such as:
· Logistics such as container management, pallet management, asset tracing etc.
· Ticketing access control
· School access system
· Office of the access control, security systems
· Government office access control, security systems
· Supermarket access control, security, vending system
· Remote machine room Management System
