01 · The Challenge
Unforgiving Mobile Environments
Deploying computing hardware inside the control cabins of heavy-duty specialized vehicles presents severe engineering challenges. Standard commercial—or even entry-level industrial—boards routinely fail due to four primary environmental stress factors.
Dirty Power
Vehicle electrical systems are notoriously unstable. Engine cranks, alternators, and heavy mechanical equipment cause sudden voltage drops and spikes.
Spatial Constraints
Control cabins have limited physical space for IT equipment. Complex wiring often leads to messy deployments and increases the risk of cable disconnection over time.
Electromagnetic Interference (EMI)
Heavy-duty trucks generate significant electrical noise, threatening the signal integrity of crucial vehicle telemetry data transmitted via CAN bus.
Continuous Vibration & Thermal Stress
Daily operation on varying road conditions subjects the hardware to constant mechanical shock and temperature fluctuations.
02 · The BITECH Solution
Engineered for the Field
To address the specific requirements of this mobile deployment, BITECH provided the AX-234BT industrial motherboard, explicitly designed to sustain high-performance computing in harsh edge environments while preventing EOL (End-of-Life) integration risks.
Overcoming Power Fluctuations
The AX-234BT is engineered with a DC 9-36V wide-voltage power input integrated with Over-Voltage and Over-Current Protection (OVP/OCP). This allows the motherboard to absorb severe power fluctuations and load dumps from heavy-duty vehicle batteries without needing external voltage regulators.
Streamlined Integration
By positioning all critical interfaces (1× HDMI, 1× DP, 4× USB, 2× RJ45, 1× RS232, 1× RS485+CAN, and Audio/Mic) on one edge of the board, system architects can drastically simplify cable routing, reduce enclosure footprint, and decrease overall deployment time.
Safeguarding Vehicle Telemetry
We strictly adhere to the 60Ω impedance matching rule for the CAN bus architecture. Both RS485 and CAN interfaces feature 4000V galvanic isolation( Option) , successfully protecting logic circuits from high-voltage transients and ensuring zero data loss during high-EMI conditions.
03 · Quality Control
Verifying Reliability Before Deployment
A design is only as good as its testing data. To guarantee the AX-234BT would survive the Danish fleet’s daily operations, BITECH subjected every unit to a rigorous, multi-stage QC procedure prior to shipment.
Thermal Burn-In (-40°C to 70°C)
Each populated board (CPU, RAM, SSD) underwent an exhaustive 18-to-24-hour thermal burn-in cycle at extreme temperature thresholds (-40°C to 70°C) to validate thermal stability and component resilience.
Full-Load I/O Diagnostic
Following the burn-in phase, boards were subjected to a 100% full-interface diagnostic under sustained maximum compute inference and data transfer loads.
Data-Driven Verification
Using a dedicated 4-monitor QC workstation, technicians verified the continuous throughput of the dual 2.5GbE RJ45 ports, the stability of display outputs, and the structural integrity of every serial interface.
04 · The Result
A Robust, Lower-TCO Deployment
By integrating the BITECH AX-234BT, the Danish system integrator successfully deployed a robust vehicle-mounted control solution that meets the demands of round-the-clock logistics and waste management operations. Wide-voltage power delivery, isolated industrial communication, and strict pre-shipment burn-in testing combined to minimize field failures and lower the Total Cost of Ownership.
