Multi-channel timing sequence time interval measuring device

Abstract

The invention relates to a multi-channel timing sequence time interval measuring device. The multi-channel timing sequence time interval measuring device comprises a reference signal generating module, an input interface module, a hardware filtering circuit, a clock module, data memory module, a main control chip, a power module and a PC upper computer; the input interface module comprises 42-channel testing signals, and 42-channel timing sequence signals of the input interface module are sent into the main control chip through the hardware filtering circuit; the reference signal generating module generates reference signals, and the reference signals are sent into the main control chip through the hardware filtering circuit; the main control chip is connected with the data memory module and the clock module; and the main control module is connected with the PC upper computer through a TCP / IP. Through the high-speed programmable logic processing capability, multi-channel timing sequence time intervals are collected and measured, and the problems that as for an existing measuring means, the number of measuring channels is small, the measuring efficiency is low, and the measuring result does not meets the accuracy are solved.

Description

technical field [0001] The invention belongs to the field of automatic testing, in particular to a multi-channel timing time interval measuring device. Background technique [0002] With the development of modern weapons and equipment in the direction of long-range strike, precision guidance, digitization, and unmanned, modern military shooting ranges are required to have more advanced testing technology. As an indispensable part of testing the performance of modern weapons and equipment, timing measurement technology has been widely used in modern military weapons and equipment, social life and other fields. [0003] At this stage, most of the general timing measurement devices are single-measurement control or computer-based detection and control. Such a system has a single function, complex structure, and high cost. Timing measurement methods can no longer meet the precise test and measurement requirements for new equipment.
