Synchronous acquisition instrument for load and opening signals of winch hoist

Abstract

The invention provides a synchronous acquisition instrument for load and opening signals of a winch hoist. The synchronous acquisition instrument consists of a singlechip, a small scale integration (SSI) angle encoder module, a pressure sensor module, a security digital (SD) card memory, a keyboard control module, a status indication module, a universal serial bus (USB) communication module, a calendar clock module and a multipath power modules. The output end of the SSI angle encoder, the output end of the pressure sensor module, four communication ports of the SD card memory, the output end of the keyboard control module, the input end of the status indication module, the USB communication module and the output end of the calendar clock module are connected through input / output (I / O) ports of the singlechip; and the output ends of the multipath power module are connected to voltage input ends of the singlechip and the SD card. The instrument synchronously acquires data, provides data support and reference for reasonable utilization and accurate scheduling of water resources, and has the characteristics of high memory capacity, small volume, high adaptability, simplicity, reliability, convenience for use, high portability and the like.

Description

technical field [0001] The invention relates to a signal synchronous acquisition instrument, in particular to a signal synchronous acquisition instrument for the load and opening of a winch type gate hoist. Background technique [0002] At present, in the winch gate hoist system, the accurate measurement and control of the lifting capacity (load, load) and opening (lifting height) of the hoist, door machine, crane and other hoisting equipment is an important task for various water conservancy projects. It is an indispensable and important condition for the safe operation and safe production of automation engineering. In recent years, the hoist hoist uses a conventional height load meter, which usually only measures the height and load extensively. There are only some simple overcurrent protection, upper and lower limit switch protection, and tensile load protection, etc., which have major technical hidden dangers. . The synchronous acquisition of load and opening signal is...

Problems solved by technology

In recent years, the hoist hoist uses a conventional height load meter, which usually only measures the height and load extensively. There are only some simple overcurrent protection, upper and lower limit switch protection, and tensile load protection, etc., which have major technical hidden dangers.

The synchronous collection of load and opening signals is not paid attention to, and the relationship is not accurate
