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 GPS location management, Combine with GPRS RFID
function, develop ET7903 GPS&GPRS UHF RFID Reader, it able to real time
send GPS location and 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.
ET7903 GPS&GPRS HF Reader is
mainly used in school bus, government bus, factory bus, shuttle bus etc.
2. Feature
· Industrial Design
ET7903 RFID Reader 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, Reader will restart automatically. Reader is very suitable for
long-term continuous work applications.
· GPS locating
Real-time checking the location of the vehicles, terminal
device will automatically report position, monitoring Center will automatically
pop-up map showing the current location of vehicles.
· Oil and Electricity enable/disable
If special case, Monitoring center can remote control to
cut off any vehicle's circuits and gas immediately, of course, you can restore
electricity supply at any time.
· Emergency help
When vehicle face emergency situation and need help,
after the drive press emergency button, within 1 second, the alarm information
will upload the location to monitoring center. It will be in accordance with
the relevant procedures.
· Over speed alarming
Monitoring center can set the max speed of any of the
vehicle, will alarm to the monitoring center if over speeded.
· Main and backup data center
ET7903 RFID Reader support main and backup data center, user can set both
main data center IP address or domain name, when Reader fail to connect with main data center, it will
try to connect backup data center automatically.
· TAG buffer
ET7903 RFID Reader can save the TAG card information in the NVRAM buffer,
if the GPRS network is abnormal, the reader 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 reader power lose, Tag data will
still save in the NVRAM. Reader buffer can save max 3000 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,
readers 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.
· Embedded Temperature sensor
ET7903 RFID Reader built-in temperature sensor can real-time monitoring of
environment temperature, and the outside TE port can be extended to the user
device surface to monitoring equipment temperature.
· SMS Remote Restart
ET7903RFID reader supports SMS remote control, users
can query the device working status through SMS, and also user
can reboot reader through SMS.
· DO port programmable output
RFID Reader 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.
· Zone type
DI ports
support zone type setting which can be set to as common zone, delay zone,
intelligent zone, emergency zone, home zone, according to the user site
conditions and sensor type, set the correct zone type to prevent false alarm,
missing alarm.
· SMS Backup
Communication with the RFID data center through GPRS; if GPRS disconnect,
FAM can send the TAG information via SMS for backup tunnel.
· SMS password, RFID TAG, Keypad password, Fingerprint Authentication,
Timing Arm/Disarm
Reader support multiple Arm/Disarm function, it can perform a specified
time every day to Arm/Disarm; FAM also support any mobile phone number via a
password to Arm/Disarm; RFID TAG way to Arm/Disarm; Fingerprint authentication
to Arm/disarm. After the instruction is executed successfully, FAM will send
the Arm/Disarm information to the administrator phone as well.
· USSD calls fee inquiry, AGPS base station location
Reader
supports USSD way to check SIM card calls fee and inquiries AGPS base station
positioning. through AT commands, we can check SIM card calls fee, and
recharger SIM card on time to prevent arrears that affect the normal operation;
also, we can use AT command to check base station code, it is able to locate
the position of the device.
· LED indicator to display Arm and Disarm
Reader DO
port can be connected to 12V dual color LED lights, and displays the current
Arm and Disarm status. Red indicates the FAM is ARM status, Green indicates FAM
is Disarm status.
· TAG link to DO output
Reader
support TAG link to DO port output function, with the DO programming output
function, we can connect a LED and buzzer on DO port, and then we would know
TAG result according to the LED light and buzzer.
· Clock synchronization
RFID Reader support clock synchronization; it can read the clock from SMS
or get clock from management platform by GPRS.
· Graphical configuration software
ET7903 RFID Reader 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.
