PCM-6851R data acquisition unit
Overview
PCM-6851R data collector is a high-precision vehicle comprehensive performance test equipment with differential GPS measurement function. It adopts new technology and has a built-in GPS speed measurement module. It covers all the functions of a car tester. It can complete automobile power performance test, braking performance test, traction performance test, fuel consumption test, coastdown test, speedometer calibration, steep slope test, ABS test and other automotive road tests that meet national standards. It adopts vehicle-mounted thick aluminum alloy chassis and The German original connection socket has high reliability.
●Main Features
- Differential GPS measurement system, which can test the vehicle brake offset
- Using microcontroller + FPGA architecture, hardware trigger logic, reduce latency
- Using high-precision hardware speed measurement method, the minimum speed measurement cycle is 1ms
- The data collector has built-in AD converter, multi-channel forward and reverse counters and high-performance microprocessor. The synchronous measurement logic is constructed by a large-scale gate array, and the test accuracy is high.
●Measurement parameters
- Vehicle speed, time, distance, brake offset, fuel consumption, MFDD, pedal force, pedal displacement, brake line pressure, traction force, engine speed, wheel speed, instantaneous speed, instantaneous wheel spin (braking slip) ratio, average speed , Average wheel spin (braking slip) ratio, etc.
