  • Description
  • Technical index
  • Interface

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 communicates with a notebook computer through a USB port. It can complete automobile power performance test, braking performance test, traction performance test, fuel consumption test, taxi 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 access signal of the fuel consumption test interface is a quadrature TTL double pulse signal, which has the function of anti-reverse jitter

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 slip (slip) rate, average speed , Average slip (slip) rate, etc.
