Vehicle Traveling Driving Recorder GPS device support  GSM GPRS communication modes

I System introduction

GPS Vehicle traveling recorder is a set of the high performance MCU which consists of our many years’ vehicle electronic experiences, and the high researching and developing teams, it isa digital and electric recording device which records and stores driving speed, time, mileage and other information about vehicle driving and could export data through interface. Interior integrate the GPS module and GPRS/CDMA communication module, it could be upload the location information, over-speed, fatigue driving, doubtful data, dispatching the letter information, uploading the photos etc through GPRS / CDMA. GPS vehicle traveling recorder also named DB44 all in one device.

Working principle:

when the vehicle is moving, the GPS Vehicle traveling recorder receives satellite (GPS) signals to obtain information such as longitude, latitude, altitude, time, speed, direction and satellite service conditions through calculation, and transmits the aforesaid information to the remote scheduling and monitoring center (or data center) with GPRS/CDMA network, and then the vehicle administration department conducts real-time remote scheduling, monitoring and management through a website which integrates GIS electronic map or through a GPS scheduling, monitoring and management software.

Application area:

With compacted structure, our GPS Vehicle traveling recorderis installed easily, and enjoys high stability, high performance and price ratio and low power consumption. Being available for external SOS key, oil and power failure trigger switch, monitor MIC, handset, camera or oil flow sensor, vehicle driving recorder and navigator, etc., it is suitable for logistics industry, long-distance highway passenger transportation, hazardous materials transportation, bus company, vehicle leasing industry and taxi trade.

IIPrecautions

1. Please ensure that you buy a SIM card which complies with communication requirements and provides normal service (as for GPRS, please consult your local operator to ensure that the SIM card is enabled for GPRS function; and CMnet is the APN in Chinese mainland) If for the special card, please provide the special APN. China Unicom & CDMA no need to set.

2. When connect the cables, do not put the cables into the high temperatures and the place where easily could be squeezing, meanwhile, it could not pull the cables too straightly in case broken the interior wires, the circuit of the terminals and vehicle must be packed well by insulating tape or glue protector, and keep it stable by the ribbon.

 3.Ensure that all equipment and cables are connected properly prior to connecting the terminal power supply. Do not install or disassemble the terminal when being energized; switch off the power supply at first if there is any omission or connection error.

4. Refer all installation and servicing of GPS Vehicle traveling recorder to dealers authorized by us or professional maintenance personnel of local after-sales office. The user is not allowed to remove or repair the terminal without our consent otherwise any damage caused by accordingly is excluded from the warranty.

5. Do not connect the GPS antenna to the GPRS/CDMA port of the terminal, similarly, do not connect the GPRS/CDMA antenna to the GPS port of the terminal otherwise the terminal fails to work normally.

6. As a wireless communication device, the power supply of the terminal shall be switched off when entering oil depot or sites with dangerous goods.

7.As a low power wireless transmitter and receiver, GPS Vehicle traveling recorder receives and transmits RF signal during operation. To avoid EMI or non-compatible configuration, please stop using the terminal in a place with relevant notice.

 8.Keep the vGPS Vehicle traveling recorder dry; contact local dealer or after-sales office immediately when being exposed to dripping or splashing, and do not start the vehicle prior to consultation otherwise we’ll assume no liability for any damage caused by accordingly.

 9.GPS receives signals from the satellite in the sky; as being not synchronous with the earth, the satellite keeps changing its position against the vehicle. Therefore, the receiving effect is not good in some period of time (which varies in different regions) when the relative angle of satellite is small and signal tends to be affected by shielding effect generated by obstacles such as buildings. Generally, the bad GPS positioning effect occurs almost in a same period of time each day in one region.

1. Self-check

After power-on, the data recorder will inspect system parts and
