PCM-6851A data collector
  • Description
  • Technical index
  • Interface

PCM-6851A data collector is a new generation of virtual instrument based on notebook microcomputer. It adopts technology and has built-in GPS speed measurement module. It covers all the functions of automobile tester. It can communicate with notebook microcomputer through USB port to complete automobile power performance testing and manufacturing. Dynamic performance test, traction performance test, fuel consumption test, coasting test, speedometer calibration, steep climbing test, ABS test and other automobile road tests that meet national standards, using vehicle-mounted thick aluminum alloy chassis and imported original connection sockets, which have a high Reliability.

●Main Features

Using microcontroller + FPGA architecture, hardware trigger logic, reducing the delay to a small

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, 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) Shift) rate and so on.
