Rugged Design (for In-Vehicle GW)




Challenges 
Unstable and poor quality power  source. The voltage transient will cause critical damages to in-vehicle devices. Other power challenges include load dump, jump start, cold crank, and low power consumption if vehicle is off.
Vibration and shock environment. Vibration is caused while vehicles are moving over rugged terrain. In-vehicles devices will easily get problems because of continuous vibration.
Extreme temperature. It’s easy to reach very cold or very high temperature in vehicle environment. It will cause in-vehicle device overheat or can’t be activated.
Electromagnetic interference by other in-vehicle devices.
•Zcomax  Solution
DC 9-36V wide-range power input, compliant with ISO7637-2 and SAE J1113 cold crank requirement.
Advanced power management with ignition sense for delay power on and delay power off features.
Ruggedized metal case with mounting bracket, compliant to MIL STD-810G vibration/shock regulations.
Industrial-grade components selection that can support -20~60°C or -30~70°C working temperature.
Compliant to E-Mark or SAE J1113 electromagnetic susceptibility requirements.

GNSS (Global Navigation Satellite System)

Function for
Retrieve GNSS data from satellites and send to remote operation center periodically or save in local storage.
Global positioning with multiple GNSS systems, including GPS, and optional for GLONASS, Galileo, or BeiDou
Mandatory for varieties of LBS (Location-Based Service) applications, such as advertisement, emergent call.
Easy integration with AVL (Automatic Vehicle Location) applications, for managing fleet of service vehicles.
Other value-added applications, such as asset tracking, electronic toll collection, intelligent transport system.  
Implemented by
Activate GNSS feature in gateway and finish settings of cellular WAN.
Indicate remote host, time interval, TCP/UDP, and type of GPS data that would be sent. 
Support NMEA 0183 (compatible to 3.0) protocol, and allow customized prefix and suffix.
Configurable GPS data logging on local microSD card storage for route record tracking.
Available SDK for 3rd party to request GNSS data from remote flee management system.

OBD-II Data Acquisition

Function for
Retrieve varieties of vehicle information from OBD-II connector and send to remote center periodically.
Multi-Protocol support, including ISO 15765-4, ISO 14230-4, ISO 9141-2, SAE J1850 VPW, SAE J1850 PWM.
Diagnostic Trouble Codes(DTCs) interpreter, identify trouble instantly without heading to service center.  
User-defined real-time alerts, such as over speed limit, aggressive acceleration, hard braking, or idling.
Increase uptime of business operation, and pre-detect problems before they become expensive failure.
Decrease overall operational costs, including pay for overtime-work, fuel, maintenance, and insurance.
Implemented by
Connecting OBD cable to OBD-II connector (optional J1939) of vehicle and finish setting of cellular WAN. 
Configure real-time alerts, and indicate remote host, time interval, type of OBD data that would be sent. 
Configurable OBD data logging on local microSD card storage for driving record tracking.
Available SDK for 3rd party to request OBD data from remote flee management system.
