Handle Pressure Distribution Measurement System Based On LabVIEW

In recent years, owing to construction, decoration and other industries workers long-time use pneumatic nail gun to make the rate of cumulative injury incidence increased, part reason due to they long- time use poorly designed pneumatic nail gun handle. However, part of Chinese companies does not have pneumatic nail gun test system, and they are used to accord to experience to develop Handles, so the blindness is very large. Handle pressure distribution measurement system enable companies to design handle, will reduce the hand and arm injuries, also makes tools more comfortable and work more effectively.We designed handle pressure distribution measurement system, its principle is multiple of piezoresistive sensor real time data collection, use data collection card collect these pressure sensor voltage signal and then transmit to the computer using the LabVIEW software to program software systems to achieve signal processing, real-time display. The main work and achievements of this paper is as follows:1. In order to meet the high-precision pressure data collection, choose thin-film-type resistance sensor, through the sensor parameters, introduction sensor principles, Designed related data acquisition amplifier circuit for acquisition and amplify the signal, through data collection card with a computer connected to for data reception.2. Designed the system's software, including display, storage, playback modules. Filtering the collected signals, through the signal storage and playback module, the signal is stored in order to off-line analysis.3. The experimental test system has been tested to verify the correctness and reliability of the system.
